20100111736 | ROOTS-TYPE BLOWER ROTOR ALIGNMENT METHOD AND APPARATUS - Roots-type blowers with helical cycloidal rotors exhibit variation in leakback flow with angular position intrinsic to these rotor geometries. Calibration of individual blowers using a combination of high-resolution alignment and enhanced detection of residual noise phenomena permits noise in as-produced blowers to be significantly attenuated. Intrinsic lower limits of noise induced by leakback variation are associated with manufacturing tolerances, necessary clearances, and particular geometric considerations. Gross alignment errors (excluding contact between rotors) produce a characteristic noise pulse rate that is three times the shaft rate. Proper alignment suppresses this and reveals a pulse sequence at double this rate and at about half of the amplitude of faulty alignment. The novel process explains the error mechanisms and defines repeatable calibration methods for a mass-production environment, introducing appropriate gauges and methods for the task. | 05-06-2010 |

If you only wanted MP2 with MP3 graphics, then indeed this is not the game for you, and you are a terrible gamer.
Games change and evolve, just like people do. Max Payne was not pathetic in MP2 and MP1, but now he is. He has changed because of the death of his beloved, for he is a person, not a comic book one dimensional character.
You should never ask for the same game using "new tech." Hell that is the major issue of Call of Duty series today (which you ironically criticized here and asked for too!). CoD games are almost all the same. There is no major change. Why? Because if it is not broken, do not fix it. It is a lazy approach, but it is a safe one, financially speaking.

I don't remember the last time i've actually cursed out loud at a video game since the days of the unbeatable super AI of Kintaro on Mortal Kombat 2 for the genesis. And things are not made better by the fact that I recently played max payne 2 and i'm sorry, but why did they have to ruin such a masterpiece of gameplay? MP2 was an emotional experience for me. I really got into the story because of the way it was presented.Max's monologues were poetic and philosophical. There were some cliches, but the atmosphere was engrossing. Mostly, it was one of the few shooters that actually made me WANT to kill the enemies. I wanted them to SUFFER. For what they did. I was taking revenge on them just as much as Max was. The game was a generator of hatred. It was genius. The gameplay was genius. I never cleaned a room the same way twice. Which made the game infinitely replayable. It was like a murder sandbox with a million different ways to clean a room. I could jump from high to low, or from low to high. I could wound the enemies first in bullet time, then finish them with a leap. I could blow their chest with the shotty while flying above them , then switch to double uzis and swiss cheese the other two guys while i'm still laying on the floor , the uzis spitting bullets like a pair of fiery devils. The catharsis, the emotional release of energy was incomparable. I could do whatever the hell I wanted to do and the game LET ME do it. It was okay to do it. The story was awesome too. Max's monologues were cool. They put all the senseless violence of the city in a timeless, almost spiritual perspective. Something that did not have meaning was given meaning. In MP3 all the old Max does is gripe , gripe , gripe and complain , then drink , drink and drink (in every single cut scene) , then gripe and complain some more. Kind of like me now , but with less variety. He has ONE point to make - "I suck. Life sucks. I messed up. Here I go again." And also, in MP2 we chased a beautiful woman. There was sexual tension. There was chemistry. In MP3 we try to save the equivalent of Paris Hilton, who I would personally let be killed. We have the task of protecting some of the most cliched, repulsive , "i want to punch you in the face" type of characters i have ever seen in a video game (even the over-the-top pricks from the gta series are not as bad). None of the MOTIVATION for caring about them is here. Maybe except for the pregnant girl (who didn't stop crying in my ear the whole time). Killing enemies is more like a chore than a destiny in this game. There is none of the passion , none of the anger , none of the sadness and despair , the anguish. None of the "you killed my wife! She was my companion, she was my friend. She was my everything! And my little girl. My beautiful little angel. YOU BASTAAAARDS !!!! DIE !!! None of that , not even a trace of that can be found in Max payne 3. Taking that away , what do we have left? Gears of war with normal guns and bullet time? Why did they have to do that? But here is the things I absolutely cannot stand about this game , starting with the worst : 1. Way , way , way toooo many enemies. These are frickin ARMIES! Seriously. And that's on the lowest difficulty. The ghettos in Brazil apparently have numbers to take over north america. They keep coming. And keep coming. And more. It is unrealistic. I've never been to the favellas, but I doubt that there are that many people there as are enemies in the game. Seriously. And for a game so hell bent on absolute realism, the number of enemies would be more appropriate for an arcade game like saints row or something. And more and more over there. And more! AND MORE! With rifles, grenades and AK's! Against that I got a nine milimeter! Yeehaw! Take that , armies of foul , insult hurling portuguese speaking DEMONIZED brazillians. (seriously, after playing this game, I AM NEVER GOING TO BRAZIL! EVER!) 2. I mentioned that most enemies are "over there". The ones that are "over there" (which is most enemies in the room) , they are several pixels big, so head shots and one shot kills are a matter of pixel hunting like an old school point and click adventure, rather than good reflexes. The leap is basically reduced to moving from cover to cover. And yes, my most hated video game innovation of all time apart from the weapon limit (oh , wait , there is a weapon limit in MP3, how weird!) 3. The cover system has removed all creativity and tactics from the gameplay of MP2. In that game, you could decide how to enter and best clean up a room. The enemies were numbered and the result was a dance of death , the beautiful and poetic motion of the grim reaper. In MP3 , there is no such creativity. Especially from the middle to the end where it degenerates into something like the shooting gameplay of GTA IV. There are very few things that I hate in games today more than COVER! Ugh. ITS SOOOO BORING! AAAAARGHHH! 4. Where did the cool noir comics go? Oh, you mean the story telling device that made the original games absolutely unique? Why, we got rid of it! Of course we did. Better to do absolutely pointless cut-scenes with the game engine where max either drinks and gripes, or just walks through the worst areas on Earth like some tourist. I mean , that's like strolling through compton armed only with a glock. WTF?! And he keeps talking about making dumb decisions. Max was never pathethic. He was tortured, made mistakes , unlucky, pained. But he was never pathethic. Well, he is now. 5. I paid money for this game. I paid money for it and it crashed! I had to spend an hour trying to get it to work. This is a brand new product with stability issues. You pay for it and it doesn't work. Not to mention how heavy the game is. My rig handles CRYSIS with hd mods on super ultra graphics but Payne3 gives my RAM a run for its money. Not sure why either. 6. Max Payne is a senior bad ass detective and a hard boiled cop, YET , he takes orders and allows himself to be BOSSED AROUND by that so called partner of his, who later turns traitor. Every time he tried to boss me around I would shout at the screen and shoot at him. Max Payne works ALONE! This is not CALL OF DUTY, Rockstar! There is no , "FOLLOW". 7. I have the easiest time playing the game on whatever difficulty. I can aim, shoot and get headshots whenever I damn feel like it. That's because I'm a big fps fan so that's why I can. I used to kick Xaero's ass in Quake 3 on the hardest difficulty and was for the longest time an avid counter strike player. So no, it's not because I suck at the game that I hate it. It's not because it's easy or hard. It is because they have made it sooo booooring! They took every single cool thing about the last game and REMOVED IT! I wanted max payne 2 with max payne 3 graphics, but that was too much to ask for , I guess. Whatever. I had such high hopes for the game. And either way, I wanted to vent. I'm sure somebody will agree with me. Although most of you like the game. I actually feel better that I got that off my chest. And now that i've vented the venom out of my system into the clear blue waters of the ocean of the internet , i'll play a PROPER max payne. I'll play MAX PAYNE TWO! And I'll uninstall this ridiculous game. Peace! GrayMatter
I think your're missing the point. MAx has gone down hill and is in the pit of self loathing. He is going gun blazing because he really has a deathwish. SO I quite liked the story. MP2 was pretty stupid. The Russian gangster Vald and the commission whatever it was, silly cliched nonsense.
I agree with you about the tedious cutscences, why cant they have a short cut? Also agree that some more open world or freedom of movement would have been better than corridors. But on the whole a gritty, edgy outing for max.
I did like your post, as it reads well, I just dont agree with the bulk of it.

I agree with you. This is a crappy forced-path game, without any possibility for tactics, and without any immersion. Having played Skyrim, Dishonored, Crysis 2 and 3, FEAR 3 etc lately, MP3 comes off as a badly constructed paint-by-numbers game. Both MP1 and MP2 were excellent in comparison. Luckily I purchased it at a Steam sales.

the acacia; rock-thorn, the southern cliff in the Wady es-Suweinit, a valley south of Michmash, which Jonathan climbed with his armour-bearer ( 1 Samuel 14:4 1 Samuel 14:5 ). The rock opposite, on the other side of the wady, was called Bozez.
same as Senaah
(thorn ), the name of one of the two isolated rocks which stood in the "passage of Michmash," ( 1 Samuel 14:4 ) 6 1/2 miles north of Jerusalem.
se'-ne (ceneh; Senna):
This was the name attaching to the southern of the two great cliffs between which ran the gorge of Michmash (1 Samuel 14:4). The name means "acacia," and may have been given to it from the thorn bushes growing upon it. Josephus (BJ, V, ii, 1) mentions the "plain of thorns" near Gabathsaul. We may hear an echo of the old name in that of Wady Suweinit, "valley of the little thorn tree," the name by which the gorge is known today. The cliff must have stood on the right side of the wady; see BOZEZ. Conder gives an excellent description of the place in Tent Work in Palestine, II, 112-14.

text: BMW M3 stars in live-action Grand Theft Auto 4 film During the spring of 2013 the hotly anticipated Grand Theft Auto V, the latest entry in the highly popular game series, is due for release across markets worldwide. As anticipation for its release rises, a short live action flick by Gevorg Karensky has been released earlier this month, based on Grand Theft Auto 4 and featuring the exciting BMW M3. One of the exciting aspects of the Grand Theft Auto series is all the multiple car and motorbike chases the player can get involved in and this aspect of the game amongst other things aim to be recreated faithfully in this CGI-filled movie. The popular BMW M3 (which comes into action around the 1 minute 37 seconds mark) features centrally around the film's on-road action. WARNING - Contains some violent material and language which may possibly be deemed unsuitable for younger viewers or public viewing. http://www.youtube.com/watch?v=M94Bl06p9K4

By giving up control of its supply chain, Boeing had lost the ability to oversee each step of production. Problems sometimes weren't discovered until the parts came together at its Everett, Wash., plant.
Fixes weren't easy, and cultures among the suppliers often clashed.
"It seemed like the Italians only worked three days a week. They were always on vacation. And the Japanese, they worked six days a week," said Jack Al-Kahwati, a former Boeing structural weight engineer.
Even simple conversations between Boeing employees and those from the suppliers working in-house in Everett weren't so simple. Because of government regulations controlling the export of defense-related technology, any talks with international suppliers had to take place in designated conference rooms. Each country had its own, separate space for conversations.
There were also deep fears, especially among veteran Boeing workers, that "we were giving up all of our trade secrets to the Japanese and that they would be our competition in 10 years," Al-Kahwati said.
As the project fell further behind schedule, pressure mounted. It became increasingly clear that delivery deadlines wouldn't be met.
Each success, no matter how small, was celebrated. The first delivery of a new part or the government certification of an engine would lead to a gathering in one of the engineering building atriums. Banners were hung and commemorative cards — like baseball cards — or coins were handed out.
Those working on the plane brought home a constant stream of trinkets: hats, Frisbees, 787 M&Ms, travel mugs, plane-shaped chocolates, laser pointers and lapel pins. Many of the items can now be found for sale on eBay.
"It kept you going because there was this underlying suspicion that we weren't going to hit these targets that they were setting," said Matt Henson, who spent five and a half years as an engineer on the project.
The world got its first glimpse of the Dreamliner on July 8, 2007. The date was chosen not because of some production milestone but for public relations value. It was, after all, 7/8/7.
Tom Brokaw served as the master of ceremonies at an event that drew 15,000 people. The crowd was in awe.
It was "beyond experiencing a rock star on stage," said Dressler, a former Boeing designer. "This thing is so sexy, between the paint job and the lines and the fact that it's here now and you can touch it."
But like so much of show business, the plane was just a prop. It lacked most flight controls. Parts of the fuselage were temporarily fastened together just for the event. Some savvy observers noted that bolt heads were sticking out from the aircraft's composite skin.
Boeing CEO Jim McNerney told the crowd that the plane would fly within two months.
Instead, the company soon announced the first of what would be many delays. It would be more than two years before the plane's first test flight.
To overcome production problems, Boeing replaced executives and bought several of the suppliers to gain greater control. Work continued at breakneck pace.
"We were competing against time. We were competing against the deadline of delivering the first airplane," said Roman Sherbak, who spent four years on the project.
Then on a cold, overcast morning in December 2009, it all came together.
A crowd gathered at Paine Field, the airport adjacent to Boeing's factory. The Dreamliner climbed deftly into the sky for a three-hour test flight.

A few days remain before I present my internship report to get a master's degree. I have a few questions:
- My field advisor insulted me several times during my internship period. (He is mean, he gets angry very easily, he is bad-tempered and most importantly he is ignorant; he never knew what I must do as a trainee; it is me who proposes the tasks to him. Now that I finished the main task of my internship, he says it is useless). So I decided not to write an acknowledgement in my report: is this a bad thing to do? I mean, will the jury ask me why I did not write an acknowledgement?
- If the jury asks about my appreciation of the company where I did the internship: should I be honest in telling them what happened and that my advisor is too incompetent? Or should I lie and tell them everything was fine?
