Lab-on-a-chip technologies and the μTAS have gained importance in recent years. The integration of all functions and components needed for the analysis of a sample in a microfluidic system has to be achieved. Magnetic materials are widely used in these systems for various applications such as magnetohydrodynamic pumps and valves. Especially, in terms of separation and detection of biological sa...

CDMA (Code Division Multiple Access) is a multiple access technique based on spread spectrum methods. In a downlink signal processing, only the code of the mobile phone user is known, while the codes of the interfering users are unknown. In addition, the number of sources (users and paths) is usually larger than the code length. In this case, linear methods such as matched lter fail to estimate...

In this paper we discuss, in some depth, our restricted implementation of privilege separation for the Condor system ([1], [2]) (in the Linux environment), and, in addition, we describe our proposed architecture for communication between privilege separated daemons in the Condor system. This architecture, if adopted, would allow each daemon to conform to principle of least privilege, thus signi...

In this paper, reliability block diagram of a sounding rocket separation system is determined and also, FMEA analysis of its spring mechanism is performed. This system is based on the flexible linear shape charge crosssection system and a spring mechanism to accelerate separation. In this investigation, reliability block diagram of the separation system include mechanical and electrical mechani...

With the growing number of severe system disturbances and blackouts around world, controlled separation is becoming an increasingly important integrity protection scheme (SIPS) to save electric power from a complete or partial disintegration. A successful splitting approach should at least tackle following two well-known interrelated problems: “when split?” “where split?”. Multiple previous pub...

As the demand for the civil aviation has been growing for decades and the system becoming increasingly complex, the use of systems engineering and operations research tools have shown to be of further use in managing this system. In this study, we apply such tools in managing landing operations on runways (as the bottleneck and highly valuable resources of air transportation networks) to handle...

liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 k. the studied systems exhibit two types of liquid-liquid equilibrium (lle) behavior. the system consisting of benzyl alcohol displays type-1 lle behavior, while a type-2 behavior is exhibited by the other s...

the membrane separation technology by relying on microfiltration ultrafiltration, and reverse osmosis methods are becoming more important among consulting engineers, designers of environmental pollution control system, and industrial factories. the advantages of this technology together with its emphasis on recycling the fluid to the system and reusing the membranes have caused the membranes to...
