Most of the existing hydraulic cylinder internal leakage detection methods are laboratory testing methods, mainly pressure-holding method, measurement settlement and measuring cup method. The affects damping characteristics control system. Therefore, real-time plays an important role in characteristics. This paper first proposes a wavelet analysis-based extraction fault eigenvalues for analysis...

The most research on the power consumption of circuits has been concentrated on the switching power and the power dissipated by the leakage current has been relatively minor area. In today‟s IC design, one of the key challenges is the increase in power dissipation of the circuit which in turn shortens the service time of battery-powered electronics, reduces the longterm reliability of circuits ...

GMR sensors are widely used in many industrial segments such as information technology, automotive, automation and production, and safety applications. Each area requires an adaption of the sensor arrangement in terms of size adaption and alignment with respect to the field source involved. This paper deals with an analysis of geometric sensor parameters and the arrangement of GMR sensors provi...

This study evaluated the basic dosimetric characteristics of a Dynamic Multi Leaf Collimator (DMLC) using a diode detector and film measurements for Intensity Modulated Radiation Therapy Quality Assurance (IMRT QA). The EGSnrc Monte Carlo (MC) simulation system was used for the determination of MLC characteristics. Radiation transmission and abutting leaf leakage relevant to the LinaTech DMLC H...

The Triple gate FinFET architecture has emerged as a viable contender for the ultimate scalability of CMOS devices. FinFET structure offers better control over device leakage currents than the conventional bulk MOSFET structure. In this paper, we present the 6 transistor (6T) SRAM cell implementation using the 22 nm gate length FinFET devices modeled using a 3-D device simulator. The performanc...

The lightning current waveform has a major influence on the dynamic performance of ground electrodes. While high lightning current intensity improves the dynamic grounding performance due to ionization of the soil, very fast fronted pulses might worsen the performance in case of inductive behaviour. The previous analysis has often been based on quasistatic approximation that is not applicable t...

As the aspect ratio of the devices shrinks down, the power supply voltage should be reduced to meet low power requirements, and the threshold voltage should also be reduced to achieve high performance. This, however, leads to exponential increase in leakage current; hence the circuit’s reliability is also affected. A new domino circuit is proposed with reduced power and lower leakage for wide f...

In multi-cast scenario, all desired users are divided into K groups. Each group receives its own individual confidential message stream. Eavesdropper group aims to intercept K confidential-message streams. To achieve a secure transmission, two secure schemes are proposed: maximum group receive power plus null-space (NS) projection (Max-GRP plus NSP) and leakage. The former obtains its precoding...

As the technology is continuously scaled, leakage currents become a major contributor to the total power dissipation. A reduction in power supply voltage is necessary to reduce dynamic power and avoid reliability problems in deep sub-micron (DSM) regimes. Threshold voltage reduction accompanies supply voltage scaling to maintain the performance, but it exponentially increases the subthreshold l...

Fault detection and isolation (FDI) is a useful tool to investigate proper performance of dynamic systems. With respect to hydraulic actuators, as they are extensively used in industry, and are responsible for producing accurate displacements and high forces, FDI role is crucial. One of the phenomena that can affect the internal leakage detection is the variation in the value of fluid effective...
