In order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. In this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. Two elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-d...

   This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...

Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...

Order reduction is a common theme within the simulation, control, and optimization of complex physical processes. The mathematical models used in these computations often result in large-scale systems. For example, such systems arise due to accuracy requirements on the spatial discretization of fluids or structures, in the context of lumped-circuit approximations of distributed electronic circu...

Architecture and circuit design are the two most effective means of reducing power in CMOS VLSI. Mathematical manipulations have been applied to create a power efficient architecture of an FFT. This architecture has been implemented in asynchronous circuit technology that achieves significant power reduction over other FFT architectures. Multirate signal processing concepts are applied to the F...

background: gabaergic interneurons in the hippocampal ca1 area are mutually communicated by gap junctions (gjs) composed of connexin36 (cx36). we examined the role of cx36 in ca1 in manifestation of kindled seizures and hippocampal kindling in rats. methods: quinine, as the specific blocker of cx36, was injected into ca1, and kindled seizures severity was examined 10 min afterward. moreover, qu...
