We present a new graphic language which can serve, for instance, as models for VLSI and control systems. Its primitives are based on standard timing diagrams, and this is a great advantage over other formalisms since designers can rapidly master it. The semantics is rigorously defined in the formalism of the theory of automata on infinite words. Using this formalism, we are able to give a rathe...

For a homecare electrocardiogram (ECG) monitoring device, it is important to extract the features of the signal in real-time. The objective of this abstract is to report a successfully development of a parallel processing, real-time ECG features extraction algorithm that could be implemented using Field programmable Gate Array (FPGA) device. The implemented System on Chip (SOC) using FPGA that ...

background and purpose: many workers are exposed to workplace hazards. many occupational diseases are preventable by personal protective devices (ppds). though many workers do not use ppds or their protection by ppds is not sufficient. this study was designed to assess the quality of ppds usage among industrial workers. materials and methods: in a cross-sectional study, 648 workers from four ma...

investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...

We describe a timing analysis algorithm which can achieve the efficiency of RC tree analysis while retaining much of the generality of Asymptotic Waveform Estimation. RC tree analysis from switch level simulation is generalized to handle piecewise linear transistor models, non tree topologies, floating capacitors, and feedback. For simple switch level models the complexity is O(n). The algorith...

This technical note will first review the studies that were done for the Gun Test Facility (GTF) at SSRL, where a photoinjector similar to the one proposed for the LCLS is being tested. In Section 3 the maximum charge out of the gun for a single rf pulse is calculated. In Section 4, PARMELA simulations are used to track the beam from the gun to the end of the photoinjector. Finally in Section 5...
