OBJECTIVE The aim of this study was to develop a self-diagnostic scale that could distinguish smartphone addicts based on the Korean self-diagnostic program for Internet addiction (K-scale) and the smartphone's own features. In addition, the reliability and validity of the smartphone addiction scale (SAS) was demonstrated. METHODS A total of 197 participants were selected from Nov. 2011 to Ja...

We present the design and test of a portable multichannel neural data acquisition system. Each analog channel features a low noise (10nV/√Hz), high CMRR (83.4dB) input stage, a 4 order bandpass filter and a selectable gain (60.8dB – 100.8dB). An automatic DC restoration circuit in the input stage rejects the electrodes DC voltage mismatch. The multichannel analog signals are sampled, digitized ...

This paper presents a sensitivity-based test generation tool for analog multifrequency testing and diagnosis. The test generation procedure is based on sensitivity analysis and on fault simulation. This tool generates minimal test sets that maximize the coverage of soft, large and hard component faults and that enhance the coverage of interconnect shorts. An introduction to the problem of analo...

A Wideband Frequency Synthesizer for Built-in Self Testing of Analog Integrated Circuits. (August 2004) Wenjian Yan, B.S., Texas A&M University Chair of Advisory Committee: Dr. Jose Silva-Martinez The cost to test chips has risen tremendously. Additionally, the process for testing all functionalities of both analog and digital part is far from simple. One attractive option is moving some or all...

In previous work, we have proposed a framework for black-box conformance testing of realtime systems based on timed automata specifications and two types of tests: analog-clock or digital-clock. Our algorithm to generate analog-clock tests is based on an on-the-fly determinization of the specification automaton during the execution of the test, which in turn relies on reachability computations....

p. atlantica subsp. kurdica, with the local name of baneh, is a wild medicinal plant which grows in kurdistan, iran.  the identification of resistance gene analogs holds great promise for the development of resistant cultivars. a pcr approach with degenerate primers designed according to conserved nbs-lrr (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (r) gene...

a-chip (SoC) architectures, demands for short time to market and rich functionality have driven design houses to adopt a new core-based SoC design flow. A core-based SoC incorporates multiple complex, heterogeneous components on a single piece of silicon; these can include digital, analog, mixed-signal, RF, micromechanical, and other kinds of systems. This blurring of the boundaries between dif...

This contribution deals with an application of three different algorithms which optimize a group delay of analog filters. One of them is a part of the professional circuit simulator Micro Cap 7 and the others two original algorithms are developed in the MATLAB environment. An all-pass network is used to optimize the group delay of an arbitrary analog filter. Introduced algorithms look for an op...

Testing of analog and mixed signal circuit has often given bottleneck in the system design. Studies based on the simulation results have been presented by many authors. In this study an intelligent virtual instrument system design for the diagnosis of parametric faults in mixed signal analog circuit is presented. A benchmark R2R digital to analog converter mixed signal circuit is used for fault...
