Roxy Music Break Up, Ready Box Sets of First Two Albums
By Evan Minsker on November 3, 2014 at 10:19 p.m. EST
Roxy Music reformed in 2001—their most recent set of reunion dates took place back in 2011. When Bryan Ferry talked to Pitchfork in 2010, he discussed a hypothetical new Roxy Music album, saying it would be "more abstract and experimental" if it would ever happen. Apparently, that's not going to happen. Phil Manzanera told Rolling Stone that after the 2011 reunion, the band broke up. "I think our job is done," he said.
Roxy Music to Release Career-Spanning Box Set
By Carrie Battan on January 26, 2012 at 11:01 a.m. EST
In celebration of the band's 40th anniversary, Roxy Music will embark on a career-spanning reissue campaign. On April 2, Virgin will put out an eight-CD/four-DVD box set called Roxy Music: The Complete Studio Recordings 1972-1982. It includes eight Roxy Music studio albums: 1972's Roxy Music, 1973's For Your Pleasure and Stranded, 1974's Country Life, 1975's Siren, 1979's Manifesto, 1980's Flesh and Blood, and 1982's Avalon, along with "high-resolution audio" versions of the albums on DVD.
Bryan Ferry Talks New Solo Album, Roxy Music

"Met Bryan Ferry last night. Know what's cooler than meeting Bryan Ferry? Being Bryan Ferry." James Murphy-- a guy who knows a thing of two about coolness-- wrote that last month. And he's right. When I recently talked to the sometime Roxy Music frontman and ageless ambassador of chic, he had just returned to his London studio after a birthday celebration in Seville, Spain. And while he claims to be "much older than you'd care to imagine" at 65, Ferry could easily pass for a man in his 40s, his hair full and just wily enough, his suits bespoke.
The forthcoming Olympia is Ferry's 13th solo studio album, and his first record of mostly original material since 2002's Frantic. It finds him collaborating with an all-star cast including Radiohead's Jonny Greenwood, Scissor Sisters, Nile Rodgers, Primal Scream's Mani, Flea, Groove Armada, and Pink Floyd's David Gilmour. Not to mention Roxy Music buddies Brian Eno, Phil Manzanera, and Andy Mackay. We chatted with him about the record, Olympia cover star Kate Moss, and Roxy Music's still-potent legacy:
Bryan Ferry Recruits Brian Eno, Jonny Greenwood for New Album Olympia
By Tom Breihan on July 12, 2010 at 12:50 p.m. EDT
Last year, we reported that Roxy Music leader Bryan Ferry was working on an album with an interesting lineup of contributors that included Radiohead's Jonny Greenwood, Red Hot Chili Peppers bassist (and sometime Thom Yorke sideman) Flea, and legendary disco mastermind and Chic frontman Nile Rodgers. But that's only part of the story. Ferry's new album Olympia hits October 25 via Virgin in the UK and a whole more people will help out. UPDATE: It will be released October 26 in the U.S. via Astralwerks.
In addition to Greenwood, Flea, and Rodgers, the roster of contributors also includes the Scissor Sisters, Pink Floyd's David Gilmour, and Primal Scream's Mani. Also, Ferry teams up with old Roxy Music bandmates Phil Manzanera, Andy Mackay, and (yup) Brian Eno for the first time on an album since For Your Pleasure in 1973.

Ethanol mandate criticized in hearing held by Oklahoma Rep. James Lankford
The last few years, however, have seen a boom in domestic crude and natural gas production, along with falling demand for fuel.
And some critics, including the oil and gas industry, have called for repeal of the standard. Opponents also have blamed the standard for rising costs of feed and food, since so much corn is used to produce ethanol.
Lankford, the subcommittee chairman, did not invite a witness from the renewable fuels industry, though he had a panel of three strong critics of the standard.
In a written statement, Bob Dinneen, president and CEO of the Renewable Fuels Association, called the standard "the single most effective energy policy this country has ever known."
He called Lankford's hearing biased and said "Big Oil" had created the barrier to using more ethanol in gasoline and was now complaining about it.
"They have had years to prepare and comply with the (Renewable Fuel Standard)," Dinneen said. "Instead, they've hired PR firms and lawyers to maintain their monopoly over the fuel market."
No definition
The EPA can waive requirements of the fuel standard for a variety of reasons, including severe harm to the economy of a state, region or the United States.
Rep. Jim Jordan, R-Ohio, asked Grundler how the agency would define "severe," and Grundler said the agency had no established definition.
"Then how are you going to make a decision?" Jordan said.
"We're going to do the best we can based on what the law states," Grundler said.

With sadness and affection we mourn the passing of our friend Hugh Lloyd, who died last week. He was of course well known for his trademark comedy characterisation which evolved from his association with Tony Hancock and then Terry Scott.

Hi there peeps
We've been having some fun with some of Ashley's sets. Here's a couple of images of the lighting rig which sits above the Main Control Room. It seems the lights can flash in sequence or randomly. An ability to dim is also predicted but Ashley forgot to wire that up before we took these shots.
Modelwork is progressing!
A good question indeed. Well obviously we'd like to finish Devious. Another year has started and it's not yet done. Doubtless there's a news item like this each year. Still, Ashley has started his next lot of modelwork now (ie he's worked out what he's doing and he's sized up the materials) and David is looking at the edits trying to look for the main effects areas and Stephen has the audio work in hand.

Article: Draft Genome Sequence, and a Sequence-Defined Genetic Linkage Map of the Legume Crop Species Lupinus angustifolius L[Show abstract] [Hide abstract]
ABSTRACT: Lupin (Lupinus angustifolius L.) is the most recently domesticated crop in major agricultural cultivation. Its seeds are high in protein and dietary fibre, but low in oil and starch. Medical and dietetic studies have shown that consuming lupin-enriched food has significant health benefits. We report the draft assembly from a whole genome shotgun sequencing dataset for this legume species with 26.9x coverage of the genome, which is predicted to contain 57,807 genes. Analysis of the annotated genes with metabolic pathways provided a partial understanding of some key features of lupin, such as the amino acid profile of storage proteins in seeds. Furthermore, we applied the NGS-based RAD-sequencing technology to obtain 8,244 sequence-defined markers for anchoring the genomic sequences. A total of 4,214 scaffolds from the genome sequence assembly were aligned into the genetic map. The combination of the draft assembly and a sequence-defined genetic map made it possible to locate and study functional genes of agronomic interest. The identification of co-segregating SNP markers, scaffold sequences and gene annotation facilitated the identification of a candidate R gene associated with resistance to the major lupin disease anthracnose. We demonstrated that the combination of medium-depth genome sequencing and a high-density genetic linkage map by application of NGS technology is a cost-effective approach to generating genome sequence data and a large number of molecular markers to study the genomics, genetics and functional genes of lupin, and to apply them to molecular plant breeding. This strategy does not require prior genome knowledge, which potentiates its application to a wide range of non-model species.PLoS ONE 05/2013; 8(5):e64799.

Article: The genome of Prunus mume[Show abstract] [Hide abstract]
ABSTRACT: Prunus mume (mei), which was domesticated in China more than 3,000 years ago as ornamental plant and fruit, is one of the first genomes among Prunus subfamilies of Rosaceae been sequenced. Here, we assemble a 280M genome by combining 101-fold next-generation sequencing and optical mapping data. We further anchor 83.9% of scaffolds to eight chromosomes with genetic map constructed by restriction-site-associated DNA sequencing. Combining P. mume genome with available data, we succeed in reconstructing nine ancestral chromosomes of Rosaceae family, as well as depicting chromosome fusion, fission and duplication history in three major subfamilies. We sequence the transcriptome of various tissues and perform genome-wide analysis to reveal the characteristics of P. mume, including its regulation of early blooming in endodormancy, immune response against bacterial infection and biosynthesis of flower scent. The P. mume genome sequence adds to our understanding of Rosaceae evolution and provides important data for improvement of fruit trees.Nature Communications 12/2012; 3:1318.

Article: The draft genome of watermelon (Citrullus lanatus) and resequencing of 20 diverse accessions[Show abstract] [Hide abstract]
ABSTRACT: Watermelon, Citrullus lanatus, is an important cucurbit crop grown throughout the world. Here we report a high-quality draft genome sequence of the east Asia watermelon cultivar 97103 (2n = 2× = 22) containing 23,440 predicted protein-coding genes. Comparative genomics analysis provided an evolutionary scenario for the origin of the 11 watermelon chromosomes derived from a 7-chromosome paleohexaploid eudicot ancestor. Resequencing of 20 watermelon accessions representing three different C. lanatus subspecies produced numerous haplotypes and identified the extent of genetic diversity and population structure of watermelon germplasm. Genomic regions that were preferentially selected during domestication were identified. Many disease-resistance genes were also found to be lost during domestication. In addition, integrative genomic and transcriptomic analyses yielded important insights into aspects of phloem-based vascular signaling in common between watermelon and cucumber and identified genes crucial to valuable fruit-quality traits, including sugar accumulation and citrulline metabolism.Nature Genetics 11/2012; 45(1).

Article: Rapid development of molecular markers by next-generation sequencing linked to a gene conferring phomopsis stem blight disease resistance for marker-assisted selection in lupin (Lupinus angustifolius L.) breeding.[Show abstract] [Hide abstract]
ABSTRACT: Selection for phomopsis stem blight disease (PSB) resistance is one of the key objectives in lupin (Lupinus angustifolius L.) breeding programs. A cross was made between cultivar Tanjil (resistant to PSB) and Unicrop (susceptible). The progeny was advanced into F(8) recombinant inbred lines (RILs). The RIL population was phenotyped for PSB disease resistance. Twenty plants from the RIL population representing disease resistance and susceptibility was subjected to next-generation sequencing (NGS)-based restriction site-associated DNA sequencing on the NGS platform Solexa HiSeq2000, which generated 7,241 single nucleotide polymorphisms (SNPs). Thirty-three SNP markers showed the correlation between the marker genotypes and the PSB disease phenotype on the 20 representative plants, which were considered as candidate markers linked to a putative R gene for PSB resistance. Seven candidate markers were converted into sequence-specific PCR markers, which were designated as PhtjM1, PhtjM2, PhtjM3, PhtjM4, PhtjM5, PhtjM6 and PhtjM7. Linkage analysis of the disease phenotyping data and marker genotyping data on a F(8) population containing 187 RILs confirmed that all the seven converted markers were associated with the putative R gene within the genetic distance of 2.1 CentiMorgan (cM). One of the PCR markers, PhtjM3, co-segregated with the R gene. The seven established PCR markers were tested in the 26 historical and current commercial cultivars released in Australia. The numbers of "false positives" (showing the resistance marker allele band but lack of the putative R gene) for each of the seven PCR markers ranged from nil to eight. Markers PhtjM4 and PhtjM7 are recommended in marker-assisted selection for PSB resistance in the Australian national lupin breeding program due to its wide applicability on breeding germplasm and close linkage to the putative R gene. The results demonstrated that application of NGS technology is a rapid and cost-effective approach in development of markers for molecular plant breeding.Theoretical and Applied Genetics 10/2012; DOI:10.1007/s00122-012-1997-1 · 3.51 Impact Factor

ABSTRACT: We have sequenced and assembled a draft genome of G. raimondii, whose progenitor is the putative contributor of the D subgenome to the economically important fiber-producing cotton species Gossypium hirsutum and Gossypium barbadense. Over 73% of the assembled sequences were anchored on 13 G. raimondii chromosomes. The genome contains 40,976 protein-coding genes, with 92.2% of these further confirmed by transcriptome data. Evidence of the hexaploidization event shared by the eudicots as well as of a cotton-specific whole-genome duplication approximately 13-20 million years ago was observed. We identified 2,355 syntenic blocks in the G. raimondii genome, and we found that approximately 40% of the paralogous genes were present in more than 1 block, which suggests that this genome has undergone substantial chromosome rearrangement during its evolution. Cotton, and probably Theobroma cacao, are the only sequenced plant species that possess an authentic CDN1 gene family for gossypol biosynthesis, as revealed by phylogenetic analysis.Nature Genetics 08/2012; 44(10):1098-103.

Article: Application of next-generation sequencing for rapid marker development in molecular plant breeding: a case study on anthracnose disease resistance in Lupinus angustifolius L.[Show abstract] [Hide abstract]
ABSTRACT: In the last 30 years, a number of DNA fingerprinting methods such as RFLP, RAPD, AFLP, SSR, DArT, have been extensively used in marker development for molecular plant breeding. However, it remains a daunting task to identify highly polymorphic and closely linked molecular markers for a target trait for molecular marker-assisted selection. The next-generation sequencing (NGS) technology is far more powerful than any existing generic DNA fingerprinting methods in generating DNA markers. In this study, we employed a grain legume crop Lupinus angustifolius (lupin) as a test case, and examined the utility of an NGS-based method of RAD (restriction-site associated DNA) sequencing as DNA fingerprinting for rapid, cost-effective marker development tagging a disease resistance gene for molecular breeding. Twenty informative plants from a cross of RxS (disease resistant x susceptible) in lupin were subjected to RAD single-end sequencing by multiplex identifiers. The entire RAD sequencing products were resolved in two lanes of the 16-lanes per run sequencing platform Solexa HiSeq2000. A total of 185 million raw reads, approximately 17 Gb of sequencing data, were collected. Sequence comparison among the 20 test plants discovered 8207 SNP markers. Filtration of DNA sequencing data with marker identification parameters resulted in the discovery of 38 molecular markers linked to the disease resistance gene Lanr1. Five randomly selected markers were converted into cost-effective, simple PCR-based markers. Linkage analysis using marker genotyping data and disease resistance phenotyping data on a F8 population consisting of 186 individual plants confirmed that all these five markers were linked to the R gene. Two of these newly developed sequence-specific PCR markers, AnSeq3 and AnSeq4, flanked the target R gene at a genetic distance of 0.9 centiMorgan (cM), and are now replacing the markers previously developed by a traditional DNA fingerprinting method for marker-assisted selection in the Australian national lupin breeding program. We demonstrated that more than 30 molecular markers linked to a target gene of agronomic trait of interest can be identified from a small portion (1/8) of one sequencing run on HiSeq2000 by applying NGS based RAD sequencing in marker development. The markers developed by the strategy described in this study are all co-dominant SNP markers, which can readily be converted into high throughput multiplex format or low-cost, simple PCR-based markers desirable for large scale marker implementation in plant breeding programs. The high density and closely linked molecular markers associated with a target trait help to overcome a major bottleneck for implementation of molecular markers on a wide range of germplasm in breeding programs. We conclude that application of NGS based RAD sequencing as DNA fingerprinting is a very rapid and cost-effective strategy for marker development in molecular plant breeding. The strategy does not require any prior genome knowledge or molecular information for the species under investigation, and it is applicable to other plant species.BMC Genomics 07/2012; 13:318.

My bf and I discovered we were pregnant in November and though not prepared or expecting the surprise we were both ECSTATIC. I have always wanted a little baby girl of my own an motherhood is just my calling. After almost 19 weeks of normal checkups and ultrasounds and praying for a girl we went to the anatomy scan- the only worry on our minds being it might be a boy (who we would love and be just as excited for). The beginning was so amazing, put me to tears of joy actually seeing our baby so big and moving so much and finding tht it was indeed a girl. But all came crashing down as the gender statement was followed by finding that my baby girl has a clubbed foot, the other foot swollen with fluid, a heart defect, her hands were clenched, the head was an abnormal shape and her brain not only had fluid in it but was missing brain tissue that should have developed by now. We went to a specialist who just confirmed these abnormalities and i did an amnio to find out what was wrong. My fish results came back normal and now I'm waiting for my kariotype results
Which I should hear in about 2 days.
I am so scared of what the results will tell me, and of what the future holds. With that many abnormalities how can my baby girl survive? Idk if she will make it to birth or make it a few weeks or months after birth, I have no idea. All I know is that this is my first born, and I finally got my baby girl.. And now I am told that she is not okay.. I could not mentally handle a still birth, but termination seems like it would be just as mentally hard if she were not to survive.
I guess I just need prayers and a miracle quite frankly.

A method and control system that monitors the high frequency or commonly referred to as the "noise" component of a measurement signal to detect plugging conditions in fluid flow systems monitored by DP-cell based sensors. This high frequency component has contributions from the process factors like disturbances, user actions and random effects like turbulence. A test statistic θ(t) has been developed that monitors the proportion of variance introduced by the first two factors and the third factor. By monitoring this proportion, it is possible to detect a frozen sensor that is characterized by a dramatic reduction in the variance due to process factors over a sufficiently long detection window. The method has successfully detected a frozen level sensor using historical data from a large petrochemical plant. Unlike spectral analysis, this method works with measurements sampled at frequencies commonly achievable in a process environment. This increases the practical utility of the method. In addition, relatively simple calculations make it computationally attractive.

[0001] This invention relates to a control system and method for detecting plugging in differential pressure cells.
[0002] Sensors that provide accurate and reliable measurements are crucial in today's world of highly automated and integrated operations. Sensor failure is one of the biggest nightmares of an operator. A sensor failure is defined as the loss of proper sensing action, that is, the sensor fails to respond correctly to changes in the measurement variable it is sensing. Often a sensor failure goes undetected until it escalates into a process problem. It may then be too late to take any preventive action. The process industry is filled with real-life case studies, in which a catastrophic incident can be traced back to a failed sensor.
[0003] A differential pressure cell (DP-cell) is commonly used to measure process variables like flow and level. The DP-cell is often located close to the ground for ease of maintenance and, hence, is connected to the process through long impulse lines. These impulse lines are easily blocked by accumulation of suspended particles in the process fluid, or by uneven steam flow during tracing, or by poor insulation. As used herein, the term "frozen sensor" is used to indicate the state of a sensor (either flow or level) that contains a blocked DP-cell. A blocked DP-cell measures incorrect pressure and, thus, provides an incorrect indication of flow or level. Unlike the failure of a temperature sensor that results in the measurement reading either pegged at a constant value or widely oscillating between lower and upper limits of a range of the instrument, a frozen sensor is more subtle to detect.
[0004] Traditionally, there are two ways of detecting a frozen sensor. First, an operator may suspect a frozen sensor based on his or her experience. Second, a spectral analysis may be performed to monitor changes in the high-frequency component of a measurement signal. Pressure p(t) described at a molecular level measures the net energy transferred by random impact of atoms and molecules at any point. The pressure p(t) at any time t is given by:
p(t)={overscore (p)}(t)+p′(t) (1)
[0005] where, p′(t) represents fluctuations introduced because of turbulence and electrical interference and {overscore (p)}(t) resents the ensemble average of the instantaneous pressure calculated over a very small measurement volume. These fluctuating components of a measurement signal can often provide valuable insights into the state of the measuring device. Although the use of spectral analysis to monitor these fluctuations and deduce diagnostic states has been successful in laboratory setups, most methods require measurement frequencies in the range of 200-1000 Hz, which is rarely practical in process industries.
[0006] Thus, there is a need for an automated and predictive plugging detection system and method.
[0007] The method of the present invention detects a plugging condition in the impulse lines of a DP-cell. The DP-cell provides a sensor signal proportional to the pressure drop and, hence, the velocity of a fluid in a system. A variance factor is developed for the variance fluctuating component of the sensor signal that is mainly due to turbulence effects of the fluid; compared with a baseline value using a predetermined threshold. An occurrence of the plugging condition is signaled in response to the change in this variance factor.
[0008] The method of the invention works with well-established and prevalent sampling rates as compared to frequency based methods that require high sampling rates. Thus, the method can be deployed within established distributed control systems without changing sampling rates or data collection frequency.
[0009] According to one embodiment of the method of the invention, the sensor signal is also processed to detect a zero mean velocity condition of the fluid. The occurrence of the plugging condition is signaled when the variance factor and a non-zero mean velocity condition are developed simultaneously.
[0010] According to another embodiment of the method of the invention, the comparison is with a current value of the sensor signal, and a baseline value based on a value of the sensor signal that is calculated earlier in time than the current value. Preferably, the baseline value is dynamically updated.
[0011] According to another embodiment of the method of the invention, the current value is based on a window of N samples of the sensor signal that advances at least one sample at a time to provide a plurality of windows. The comparison of the current value and the baseline value is repeated for each of the plurality of windows. The baseline value is dynamically updated preferably based on a value of the baseline developed prior to the window of the current value. More preferably, the baseline value is updated during each of the windows over a detection window that spans a plurality of the sample windows. Most preferably, the baseline value is updated using an exponentially weighted moving average of the plurality of sample windows.
[0012] According to another embodiment of the method of the present invention, the variance factor uses only the high frequency component of the sensor signal. Preferably, the variance factor closely corresponds to turbulence effects and substantially eliminates effects due to low frequency process effects. Comparing the variance factor with the baseline value substantially eliminates effects due to working conditions of the system.
[0013] According to another embodiment of the method of the invention, the variance factor is compared to with a baseline value and a predetermined threshold. An occurrence of the plugging condition is signaled in response to the variance factor. The baseline value is dynamically updated.
[0014] The control system of the present invention includes a controller that comprises a processor, a memory and a program that causes the processor to perform a plurality of operations that correspond to the steps of the method of the invention.

[0028] According to the present invention, a test statistic is developed that measures the variance of fluctuating (high frequency) components of a sensor signal that is monitored to provide insights into the diagnostic state of the sensor. Unlike conventional statistical hypothesis testing, domain knowledge in terms of the actual sensor model is used. A 2�2 covariance matrix is constructed for the measurement of the variance introduced due to turbulence and process effects. The eigen values of this covariance matrix are monitored to provide diagnostic information. By way of example, the method of the invention is illustrated using historical data from a level sensor in a petrochemical plant. For this example, the method of the invention is capable of detecting a frozen level sensor hours before it results in a process upset.
[0029] Referring to FIG. 1, a measurement system 20 includes a DP-cell 22 that is connected via a pair of impulse lines 24 and 26 to a pair of spaced apart points on a pipe 28 to measure the flow of a fluid therethrough. A flange arrangement 30 is disposed on pipe 28 to facilitate the connection of impulse lines 24 and 26 to pipe 28. For the indicated flow direction, impulse line 24 is a high-pressure line and impulse line 26 is a low pressure line. The fluid pressure, velocity and elevation on the high pressure side are denoted by p1, u1 and z1, respectively. The fluid pressure, velocity and elevation on the low-pressure side are denoted by p2, u2 and z2, respectively. First and second flange arrangements each disposed on a respective impulse line 24 and 26 flank DP-cell 22. The first and second flange arrangements operate to facilitate the service of DP-cell 22. DP-cell 22 is operative to provide a pressure signal that is a difference between p1 and p2. According to Bernoulli, the pressure drop p1−p2 can be modeled as:
p1−p2=ρ/2(u22 −u12)+ρ(z2−z1) (2)
[0030] where ρ is the average density.
[0031] Referring to FIG. 2, another test setup 40 includes a DP-cell 22 that is connected via impulse lines 24 and 26 to a pair of spaced apart points on a process vessel 42 for the measurement of a level of liquid 44 contained in process vessel 42. Impulse line 24 is connected to process vessel 42 in the liquid containing portion of thereof, and preferably near the bottom of process vessel 42. Impulse line 26 is connected to a vapor-containing portion of process vessel 22.
[0032] Referring to FIG. 3, a level maintenance system 50 includes a liquid distillation column 52 (or any drum for that matter) that is interconnected with a sensor 54, a level controller 56 and a drain valve 58 for the maintenance of the level of liquid 44 at a desired level in distillation column 52. Sensor 54 is a DP-cell based sensor that provides an output signal proportional to a difference in pressure between the liquid containing portion and the vapor containing portion of column 52. It also converts the pressure difference signal to a level signal. Level controller 56 compares the level signal from the level transmitter 54 to a level set point. Level controller 56 provides an output signal to valve 58 to control drainage of liquid 44 from column 52 to maintain the level of liquid 44 at the set point level. The level set point is provided by a user or an advanced control application. Level controller 56 includes a computer with a processor, a memory and a plugging detection program that controls either the valve opening or the set point for a low-level flow regulatory controller. It also provides an indication of the plugging state of the DP-Cell contained in sensor 54.
[0033] Referring to FIGS. 4 and 5, traces are shown for a normal and a frozen temperature sensor (a resistance thermocouple in this case), respectively. The x-axis represents sample numbers collected at a 1-minute frequency. As shown in the FIGS. 4 and 5, there is a marked difference between a normal and a malfunctioning temperature sensor, thereby making detection of a frozen temperature sensor rather easy.
[0034] Referring to FIGS. 6 and 7, the traces of the output of level sensor 54 are shown under normal and frozen conditions, respectively (the conclusion that the sensor was frozen was deduced from what happened later on in the process). The x-axis represents sample numbers collected at a 1-minute frequency. Unlike the temperature sensor traces shown in FIGS. 4 and 5, detecting problems in a level sensor is more difficult as there is very little difference between the normal and frozen conditions. To a casual observer, the trace under normal conditions appears to be more flat-lined. A small transient around sample numbers 500-700 in FIG. 7 provides contradictory evidence to the fact that the sensor is indeed frozen. This is because the frozen DP-cell may respond to changes in upstream or downstream static pressure changes, albeit incorrectly.
[0035] Referring to FIGS. 8 and 9, traces of the output of level sensor 54 and the output of level controller 56, respectively, show the subtlety of the frozen sensor detection problem. FIGS. 8 and 9 are continuations of FIGS. 6 and 7, respectively. From FIGS. 8 and 9, it is clear that level controller 56 starts to windup as a result of the frozen sensor around sample number 4250. This process continues and leads to a loss of level and subsequent process upset. It is at this point, that the operator realizes that the level sensor was frozen. This is a commonplace occurrence in the process industry, wherein an apparently small sensor problem leads to major upsets.
[0036] Referring to FIGS. 3 and 10, a separate level sensor translator 60 is provided to translate or convert the output of sensor 54, which is the DP-cell signal p(t). Level sensor translator 60 converts the differential pressure signal p(t) into a level signal L(t), which is provided to level controller 56. Level sensor translator may also include an analog to digital converter to convert level signal L(t) to a digital signal for use by level controller 56. Level controller 56 then operates on the level signal L(t) to provide an output signal m(t). The controller output signal m(t) is proportional to the error between the actual measurement L(t) and the set point Lset(t). Under a condition of a constant set point, the level-to-flow relationship can be described using the following set of model equations:
L(t)=ƒ1(p(t); m(t)=ƒ2(L(t)) (3)
[0037] Unless stated explicitly, L(t), m(t) refer to appropriately scaled values, typically with respect to the nominal range of the instrument. Since pressure is a gross effect of randomly colliding atoms and molecules, the instantaneous value of p(t) consists of two components as given by equation (1). These fluctuations in the pressure introduce corresponding fluctuations in the level measurement and the controller output as given by:
L(t)={overscore (L)}(t)+L′(t) (4)
m(t)={overscore (m)}(t)+m′(t) (5)
[0038] The component {overscore (L)}(t), {overscore (m)}(t) is an ensemble average and corresponds to a net effect of measured/unmeasured disturbances acting on the process and user initiated set point changes. These disturbances are collectively called process factors herein. The rate of change of this component is relatively slow compared to the sampling rate Δt. The component L(t)′, m(t)′ is a net effect of turbulent flows and transducer noise. The rate of change of this component is relatively fast compared to the sampling rate. The method of the present invention monitors the variance introduced by process effects compared to that introduced due to turbulence effects. A frozen sensor is signaled by a drastic change in their relative proportions.
[0039] A test statistic θ(t) that monitors various statistical properties of these fluctuations is derived below. This test statistic forms the basis of either accepting or rejecting the frozen sensor hypothesis. Mathematically, the frozen level sensor test is formulated as:
Null hypothesis H 0: Sensor is frozen
accept H 0: θ(t)>δf (6)
[0040] where, θ(t) is a function of L(t), m(t) and δf is the threshold for acceptance.
[0041] The method of the invention monitors the variance introduced by process factors and turbulence by comparing their statistical properties. This is done by applying a high-pass filter in the form of a first difference to the measurement signal. Although, the first difference may not completely remove the effect of process factors, it will reduce its influence considerably and thus make it statistically comparable to the variance introduced by turbulence. Secondly, the first difference has the effect of statistically amplifying the variance introduced by turbulence (The variance is doubled). Let ΔL(t) and Δm(t) denote the first difference, which is defined as follows.
[0042] where, t−1 denotes the instantaneous value at the previous sample. Similarly,
Δm(t)=Δ{overscore (m)}(t)+Δm′(t) (8)
[0043] Let SL 2(t), Sm 2(t) denote the variance calculated using N previous samples. Thus:
S L 2(t)=var(ΔL(t),N) (9)
S m 2(t)=var(Δm(t),N) (10)
[0044] where, the var(�) of a uniformly sampled time series variable y(t) is defined by:
[0045] Suppose N is chosen such that statistically:
[0046] In order to establish this criterion, with about 90% confidence, a minimum of 10 samples must be collected within Tmin/3 time windows, where Tmin is the smallest process time constant. For example, if the process time constant is of the order of an hour, then sampling every minute will satisfy the above criterion. For this example, 10 samples are collected every 20 minutes (one hour/3 time windows) so that at least one sample is collected every two minutes. Substituting equation (12) in the definition of S2, L(t) and S2
[0047] m(t) gives:
[0048] Equations (13) and (14) clearly show that, for an appropriate number of samples N and a sampling interval Δt, the variance of the first difference of a sampled times series measurement y(t) is composed of two components:
[0049] 1. The first component, Sy 2(t),
[0050] corresponds to a variance introduced as a result of process effects. In other words, over a window of N samples,
[0051] represents the fraction of the variance that is accounted by process factors.
[0052] 2. The second component, Sy′ 2(t), corresponds to a variance introduced as a result of turbulence and transmitter circuits. In other words, over a window of N samples, Sy′ 2(t), corresponds to a variance introduced as a result of turbulence and transmitter circuits. In other words, over a window of N samples, Sy′ 2(t) represents the fraction of the variance that is accounted by random effects like turbulence.
[0053] In addition to the physical interpretation, the two components are different mathematically. Although, the occurrence of process factors cannot be determined once they occur, the net effect on the process is systematic. The effect of turbulence, on the other hand, is random. This mathematical difference is exploited in the formulation of θ(t).
[0054] Define X(t)=└SL 2(t) Sm 2(t)┘T and the 2�2 covariance matrix cov X(t) as follows:
[0055] where, M is called the frozen sensor detection window and M>>N. Typically, M is an order of magnitude larger than N.
[0056] Consider a principal component analysis (PCA) of the covariance matrix of equation (15). A PCA decomposition of cov X(t) gives:
[Σ(t) V(t)]=pca(cov X(t)) (16)
[0057] Eigen Values: Σ(t)=[σ1(t) σ2(t)]
[0058] Eigen Vectors: V(t)=[ν1(t) ν2(t)]
[0059] Finally, define the test statistic θ(t) as follows:
[0060] At every instant, X(t) is made up of four components:
[0061] SL′ 2(t), Sm′ 2(t), of which two of these components
[0062] are due to process effects and the remaining two components (SL′ 2(t) and Sm′ 2(t)) are due to random turbulence effects. The singular values of the covariance matrix are a composite measure of these four components over the detection window M.
[0063] Consider the case such that the over the entire detection window M, Δ{overscore (L)}(t), Δ{overscore (m)}(t)≈0, thus making
[0064] From the sensor model equation (4 & 5) we get,
Sm′ 2(t)∝SL′ 2(t)∝Sp′ 2(t) (18)
m′(t)∝L′(t)∝p′(t) (19)
[0065] That is, the sample-to-sample variation in p(t), and hence in L(t) and m(t), is solely due to random turbulence effects.
[0066] Now let us examine the covariance matrix under above mentioned condition.
[0067] This makes cov X(t) singular (σ2(t)→0) and θ(t)→∞. This key result, upon which the frozen detection test is based, is re-stated formally as follows:
[0068] Theorem: Frozen sensor test statistic.
[0069] For level sensor translator 60 of FIG. 6, if {overscore (p)}(t)→0, then {overscore (L)}(t), {overscore (m)}(t)→0. The test statistic θ(t) is given by equation (16)→∞.
[0070] However, if the sensor were not frozen and was responding to process factors, each element of the covariance matrix will have contributions from
[0071] making it non-singular and resulting in a smaller value for θ(t). The theorem provides a sufficient condition under which a frozen sensor results in
[0072] and, hence, θ(t)→∞.
[0073] The frozen sensor theorem is interpreted physically as: over the entire detection window M, there was insignificant contribution to the overall variance due to process effects. If M is chosen to be large enough, then this is very unlikely to occur, unless there is some loss in the sensor response. In other words, the detection window M is chosen to ensure that the process is subjected to a minimum of one disturbance within MΔt time interval. This puts a minimum bound on the detection window M. The question that needs to be answered before choosing M is: how often do process disturbances occur? A typical value of 4-6 times the dominant time constant is a good first guess.
[0074] The next question to be asked is whether the frozen detection theorem provides the necessary condition. A zero value for
[0075] does not necessarily imply that the sensor is frozen. Consider the following example of a uniform ramp y(t)=kt:
[0076] Therefore, the above mentioned trivial case needs verification before applying the frozen detection theorem.
[0077] The principle of the detection algorithm is described graphically in FIG. 11.
[0078] Referring to FIG. 11, the test statistic θ(t) at current time t is calculated over a window 62 consisting of N sensor signal samples. This is compared with the baseline statistic developed based on a window 64 of samples taken at an earlier time T. As stated earlier, the comparison is of a ratio of a variance contribution due to process effects and a contribution due to turbulence effects with those established by the baseline. Ideally the baseline is established in a laboratory by careful calibration. However, in practice, the baseline value is preferably updated to take into account the natural aging of the physical device and associated pipes. Thus, when window 62 slides right upon arriving of a new reading, the baseline calculation is also updated using a exponential weighted moving average window scheme. Thus, the frozen sensor detection comparison is relative to baseline established T samples ago.
[0079] According to the method of the invention, the sliding baseline calculation is implemented using a recursive covariance matrix. The recursive formula is given by:
[0080] The ramp test given by equation (21) is done using a z-statistic, which tests whether the mean of the first difference is statistically non-zero.
[0081] Referring to FIG. 12, a plugging detection program 70 at step 72 obtains a series of N samples of the DP-cell sensor. Consecutive windows advance by at least one sample. Step 74 calculates a mean of the N samples of a window. Step 76 tests the mean to determine a zero velocity condition. That is, step 76 determines whether the fluid velocity is zero. For this determination, step 78 generates a Z statistic and step 80 tests the Z statistic for the zero velocity condition.
[0082] Step 82 calculates the variance of the N samples collected over the window. Step 86 updates the baseline based on the output of step 82, a frozen detection window M provided by step 88 and a previous baseline provided by step 90 by using equation (22). Step 92 implements the frozen detection theorem. That is, it develops a variance factor using the most recent N values of the sensor signal, compares it with an updated baseline value and a specified threshold. If the result of this comparison exceeds the threshold, the variance factor or yes flag is generated. Step 94 develops the eigen values by using equation (16). Step 96 uses the eigen values in equation (17) to develop the test statistic θ(t). Step 98 compares the test statistic θ(t) with the threshold and if greater, generates the variance factor flag.
[0083] Step 100 gives a frozen sensor notice or alert when the zero fluid velocity condition and the variance factor flag are simultaneously developed.
[0084] During the frozen sensor development phase, the decisions about the following parameters are made:
[0085] 1. The number of samples, N, used in the calculation of the sample variance given by equations (13) and (14)
[0086] 2. The detection window size, M. As mentioned earlier, the larger the size, the less likely of false positives.
[0087] 3. The detection threshold, σf.
[0088] The method of the invention was applied to an example of a petrochemical plant, with a sampling rate of 1 min. For this example, N=10 and a detection window of M=50�N=500 samples was chosen. In order to determine the detection threshold, σf, the test statistic θ(t) was calculated using data segments over a two year period for which the operator reported no anomalies.
[0089] FIGS. 13-16 show traces of the test statistic θ(t) for four normal modes of operation for the level sensor. As shown in FIGS. 13-16, θ(t) is relatively the same for the four traces. A threshold of 1.6 was chosen based on visual inspection. The traces of FIGS. 4-7 were developed from this same example. As shown in FIGS. 4-7 and discussed above, it was quite a challenge for the operator to detect a frozen sensor.
[0090] Referring to FIG. 17, traces 110 and 112 of the test statistic θ(t) for the same sensor is shown under normal and frozen conditions, respectively, for the same value of N, M. Trace 112 demonstrate that the test statistic θ(t) for the sensor is approaching a frozen condition as its magnitude for the frozen condition is an order of magnitude higher than trace 110 for a normal sensor (remember that the test statistic uses a logarithmic scale). Using a threshold of 1.6, the problem could have been detected at least a day in advance. As discussed earlier, frozen sensor detection is a very subtle problem. Heretofore, the operator was able to detect this only when the controller wound-up completely. In other words, for about a day, the process was operating with an incipient problem, oblivious to the operations team.
[0091] As mentioned earlier, the method and control system of the present invention monitors the relative proportion between the variances introduced due to process effects and due to turbulence. If the sensor is responding to process effects, additional variance is added to the covariance matrix making it less singular. This is evident from the scatter plot shown in FIG. 18. There is no dominant direction along which the variance is scattered indicating that the covariance matrix is not singular. On the other hand, as explained earlier, the covariance matrix for a frozen sensor approaches singularity. This implies that there a dominant direction along which the variance can be explained, making the columns of the covariance matrix redundant. This can be seen in FIG. 19, which clearly shows a dominant direction and hence absence of any cross-directional scatter that is normally introduced when the sensor is responding to changes in the process factors.
[0092] The present invention having been thus described with particular reference to the preferred forms thereof, it will be obvious that various changes and modifications may be made therein without departing from the spirit and scope of the present invention as defined in the appended claims.

For the chat thread people it is.
Good thing I don't go there.
I went to this thread to escape. >.>
Well, I can't really say I've come here to escape, since I don't post very often outside of this part of the forum anyway. xD
I go here, the chat thread and, The Garden Grotto, BW2 and VG. That it, lol. oh and The War Room when I actually play a mafia game.
I go here, a few other F&G threads, and two private RPs I'm in. Aside from that, all my chatting is done in VMs and social groups.
I also talk over VM and PM, thats it, I dont even go to social groups.
There are two or three I'm in that were made for the sole purpose of group chatting. ^^; In fact, I own one of them.

Classic Studio Postmortem: Lucasfilm Games
Before LucasArts, there was Lucasfilm Games. From a small startup within a medium-sized (and very famous) film company, this group grew from 1982 to 1990 to become one of the most popular game companies of its day.

Monkey Island, ahhh such happy memories. And let's not forget Tie Fighter, and X-Wing either.
Great studio, that is sorely missed.
Monkey Island series, Loom, Indiana Jones and the Fate Of Atlantis, Sam & Max. Fond memories, playing with the lights off and a cup of coffee in the middle of the night, the glowing light from a CRT... those were the times
Rubber chicken with the pulley in the middle. Incredibly creative guys! :D I see the same spirit in Double Fine right now. Just watch Amnesia Fortnight videos.
Sadly about the only game I played from the early LucasArts games was Maniac Mansion on NES....
game kicked ass though, never did beat it but I was able to get most of it figured out....
I really came in about when Dark forces came out....one of the best Star Wars games for me was SOTE on N64, I could still play the crap out of it....also Rogue Squadron was one of my faves....
It's cool hearing what went on behind the scenes like this....
I would love to see another Tie-Fighter game.
Sam & Max Hit the Road was the best point-n-click adventure game back in the day!
You know what would be great? An updated version of Maniac Mansion for Steam and PS4. Hell, how bout the whole Monkey Island series for a re-release?
Ah, I freakin love their games so much. They need to get the old crew back together and do a new one already.
@jonnyc0mbat Man I feel bad for having not played any of those games yet....
I was so deprived as a kid. ^_^ Although I did spend like half my childhood playing Dark Forces.
@Patohua1 Monkey Island 1 has special edition, the same with MI2. MI3 is still beautiful, because it looks like cartoon. The rest of these game were released in the 2000's. But I agree that they need their place on GOG.com.
