Scientia Iranica is a peer-reviewed scientific journal published by Sharif University of Technology (Tehran, Iran). It was established in 1991 and covers theoretical and experimental research in technical sciences and engineering. Starting in 2011, the journal is published open access. The editor-in-chief is Abolhassan Vafai (Sharif University of Technology). Background The journal is divided in 6 sections called "Transactions". Transactions A: Civil Engineering This section covers civil engineering, which includes, but is not limited to, structural engineering, engineering materials, coastal and harbor engineering, construction management, environmental engineering, geotechnical engineering, highway engineering, information technology, railroad engineering, surveying and geospatial engineering, transportation engineering, tunnel engineering and water engineering. Emphasis is on analytical, experimental and numerical works. Transactions A is published bimonthly. Transactions B: Mechanical Engineering This section covers mechanical engineering, which includes, but is not limited to, aerodynamics, automation and control, biomechanics, design and manufacturing, fluid and hydromechanics, kinematics and dynamic systems, mechanics of continua, mechanisms and robotics, mechatronics, microelectromechanical systems, and thermal systems. Emphasis is on analytical, experimental, and numerical works. Transaction B is published twice a year. Transactions C: Chemistry and Chemical Engineering Ths section is divided into two subsections: "Chemistry" and "Chemical Engineering". It covers all aspects of applied and theoretical chemistry. Transactions C is published biannually. Scientia Iranica has published a special issue in this section dedicated to the lifelong achievements of George V. Chilingar. Transactions D: Computer Science & Engineering and Electrical Engineering This section is also divided into two subsections: "Computer Science & Engineering" and "Electrical Engineering". The first covers computer science and engineering, which includes, but is not limited to, artificial intelligence, compilers, computer architectures, computer dependability and security, computer networks and distributed systems, data management, design automation and configurable computing, digital signal processing, embedded systems, operating systems, processor and system architectures, real-time systems, soft computing, software engineering, theoretical computer science, verification, test and design for test. The second subsection covers electrical engineering, which includes, but is not limited to, information theory, encryption secure communications, wireless communications, satellite and radar, control systems, quantum electronic devices, microelectronics, RF integrated circuits and systems, biomedical engineering and imaging, power electronics, energy management systems, photonics, nanophotonics, electromagnetic, antenna and propagation, optical networks and communications, communication theory, and data networks. The subsection on electrical engineering has published special issues dedicated to the lifelong achievements of John G. Webster and Lotfi A. Zadeh. Transactions D is published twice a year.
