We present the Optimization Method for Electron Multiplying Charge-Coupled Devices (EMCCDs) of Acquisition System SPARC4 (OMASS4). The OMASS4 uses as figures merit signal-to-noise ratio (SNR) and acquisition rate (AR) a function operation mode CCDs. Three different modes optimization are included in OMASS4: (1) SNR only; (2) AR (3) both simultaneously. first two calculate an analytical maximiza...

the steady state effect of vertical fins is assessed on a photovoltaic/thermal solar air heater having a double pass configuration in which fins are placed in the lower channel perpendicular to the direction ofair flow. air passes through the upper channel of the air heater and before passing in the opposite direction through the lower channel. the effects of design, climatic and operating para...

Thermodynamic analysis of a novel combined system which is combination of methane fired gas turbine cogeneration system (CGAM) with a supercritical CO2 recompression Brayton cycle (SCO2) and an Organic Rankine Cycle (ORC) is reported. Also, a comprehensive parametric study is performed to investigate the effects on the performance of the proposed system of some important parameters. Finally, a ...

In a modern operating room, usually a plethora of imaging devices is available. These come with at least one monitor each and additional, wall-mounted monitors are often available to review patient data and pre-operative imaging. Due to sterility constraints and limited space in the operating room (OR), most of these devices have to be organized around the operating table with some distance. Th...

The CHORUS open microkernel technology is being extended to address the specific needs of real-time embedded systems. This effort results from a concerted action between telecommunication systems manufacturers, hardware technology providers, and Chorus Systems. It is performed in the context of the STREAM project, supported by the European Union Esprit Program. This paper outlines the decomposi...

the steps taken in designing a loop reactor for bulk propylene polymerization are discussed. the roles played by several parameters like particle growth factor, catalyst activity and solid fraction on reactor volume at different operating conditions are investigated. at first, based on a fixed production capacity and specific rate of catalyst, reactor volume is determined. next, the length and ...
