Abstract The quantization-based approaches not only are the effective methods for solving problems of approximate nearest neighbor search, but also effectively reduce storage space. However, many usually employ fixed nprobes to search process each query. This will lead extra query consumption. Additionally, we observed that as number points in cluster center product quantization increases, cost...

introduction: pulmonary tuberculosis is major problem worldwide and it is estimated one third the world population are already infected and each year 9 million people develop full blown tuberculosis of these 3 million die of the disease, annually. delay in diagnosis and treatment are major problems that play a significant role in all aspect of the disease from patient treatment to transmission ...

in this study, the effect of audit quality on agency costs and information asymmetry has been examined. among the accepted companies 99 ones in tehran stock exchange were selected for statistical samples from 1385 to 1392 in order to attain the research purposes. to measure the audit quality, it has been used the observable variables such as the percentage of institutional investors, the type o...

Due to technology scaling and increasing clock frequency, problems due to noise effects lead to an increase in design/debugging efforts and a decrease in circuit performance. This paper addresses the problem of efficiently and accurately generating two-vector tests for crosstalk induced effects, such as pulses, signal speedup and slowdown, in digital combinational circuits. We have developed a ...

An Early Completion technique is developed to significantly increase the throughput of NULL Convention self-timed digital systems without impacting latency or compromising their self-timed nature. Early Completion performs the completion detection for registration stagei at the input of the register, instead of at the output of the register, as in standard NULL Convention Logic. This method req...

The asymmetry in the time delay for light rays propagating on opposite sides of a spinning body is analyzed. A frequency shift in the perceived signals is found. A practical procedure is proposed for evidencing the asymmetry, allowing for a measurement of the specific angular momentum of the rotating mass. Orders of magnitude are considered and discussed. A well known effect of gravity on the p...

This paper addresses the problem of efficiently and accurately generating two-vector tests for crosstalk induced effects, such as pulses, signal speedup and slowdown, in digital combinational circuits. These effects are becoming more prevalent due to short signal switching times and deep submicron circuitry. These noise effects can propagate through a circuit and create a logic error in a latch...

We study the escape rate of a particle in metastable potential presence dissipative bath coupled to momentum particle. Using semiclassical bounce technique, we find that this is exponentially enhanced. In particular, influence dissipation depends on slope barrier tunneling through. investigate also baths position, and particle, respectively. case exhibits non-monotonic behavior as function coup...
