Modern frameworks for development of graphical interfaces are using the native controls of the operating system. Because of that they are using operating system events model for inter-component communication. We consider a method to increase inter-component communication speed by sending messages from one component to the other passing over the operating system. Besides the messages subscriptio...

This note evaluates several hardware platforms and operating systems using a set of benchmarks that test memory bandwidth and various operating system features such as kernel entry/exit and file systems. The overall conclusion is that operating system performance does not seem to be improving at the same rate as the base speed of the underlying hardware. Copyright  1989 Digital Equipment Corpo...

Recent technology trends have emphasized low power, single supply operation. The LT1016, although capable of such operation, does not include ground in its input range. As such, it must be biased into its operating common mode range for practical single supply use. A new device, the LT1394, maintains the speed and application civility of its predecessor while including ground in its input opera...

Nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. Inthis research, the application of Response Surface Methodology (RSM) was highlighted to investigate the effects of biodiesel-diesel blends (B0, B20, B50 and B100), engine operating parameters (engine load and  speed) on CO2 emission of a diesel engine. The experiments were conducte...

The core methodology of the Highway Capacity Manual (HCM) 2010 for freeway analyses is based on Free-Flow Speed (FFS). Moreover, weaving segments are major elements of freeway facilities that form where two one-way traffic streams intersect by merging and diverging maneuvers. Hence, this study used three different methods to compute FFS of a ramp-weaving segment, and then employed the proposed ...

BACKGROUND Cells are not mixed bags of signaling molecules. As a consequence, signals must travel from their origin to distal locations. Much is understood about the purely diffusive propagation of signals through space. Many signals, however, propagate via signaling cascades. Here, we show that, depending on their kinetics, cascades speed up or slow down the propagation of signals through spac...

In this paper we present a design procedure for disturbance attenuation with internal stability of a rotor supported by mag netic bearings over the whole interval of the rotor operating speeds The nonlinear gyroscopic equations can be simpli ed to a set of linear time varying di erential equations owing to the linear dependence of the rotor speed in the plant dynam ics For rotors operating in h...

In this investigation, roll compaction/dry granulation (RCDG) process was optimized for formulation of model amorphous drug candidate with fine-fluffy nature and poor flowability. Three operating parameters the roller speed, the hydraulic pressure and the granulator speed on the Alexanderwerk WP 120 Pharma Roll Compactor were varied. The planned response variable for study was % retention over ...

In this paper, we proposed a methods of implementation of intelligent controller for speed control of an induction motor using indirect vector control method has been analyzed in detail. Induction motor is used in many industrial applications of the total used electrical energy. This paper proposes a new control scheme based on artificial neural networks to obtain certain torque and speed opera...
