results the prevalence of excessive mobile phone use was 36.7% on the students. there was a significant relation between the prevalence of excessive mobile phone use and mental health status in general (p > 0.05), and also somatization (p < 0.05), anxiety and depression specifically (p < 0.05), but no significant relation was found between the excessive mobile phone use and social dysfunction (...

During the coking process in coal chemical industry, the stability of gas collector pressure is an important guarantee for the normal production of coke oven. This paper combines the adaptive fuzzy control algorithm and the fuzzy decoupling rule to control the gas collector pressure, and coordinates the entire system through the establishment of pre-header suction supervisory control. The speci...

We propose an effective methodology in which a distributed garbage collector may be derived from a distributed termination algorithm and a centralized garbage collector in a manner that preserves interesting properties of the original collector, such as completeness. To illustrate our technique we show how two distributed termination algorithms, credit recovery and task balancing, may be suitab...

 We are working on scheduling of garbage collector as a concurrent thread for time-constrained applications in Common Language Infrastructure (CLI). We have implemented an incremental garbage collector with fine-grained write barrier in MONO, an opensource implementation of CLI. Our collector is based on existing conservative garbage collector of Boehm et al. By conducting benchmarking experim...

Common to many high-level, declarative and object oriented languages are the use of dynamic dispatch and garbage collection. Dynamic dispatch is the mechanism by which the selection of a method to run, based on both its signature, and the type of one or more of its arguments, is made. A garbage collector is responsible for efficient ‘recycling’ of memory that is no longer needed, termed ‘garbag...

In this paper, we report the development of a high breakdown voltage InGaP/GaAs HBT process for low-to-mid power and high-voltage power amplifier operation. To achieve the high-breakdown InGaP HBT, two different collector designs and collector-etch processes were investigated. The first device process approach uses a thick GaAs collector with low n doping. The process challenges and considerati...

First, the limits of low-level parallelism for a collection of real-world programs are investigated and Wall's results are veri ed. Maximum parallelism of symbolic benchmarks is investigated on both superpipelined and superscalar architectures. E ects of register renaming are considered. We then examine the e ects of garbage collection strategies on low-level parallelism. In particular, we exam...

A four stage asymmetric type depressed collector has been designed for the Israeli mm-wave FEM that is driven by a 1.4MeV, 1.5A electron beam. After leaving the interaction section the spent beam has an energy spread of 120 keV and 75pmmmrad normalized beam emittance. Simulations of the beam transport system from the undulator exit through the decelerator tube into the collector have been carri...

The shape of a solar collector is an important factor in solar-to-thermal energy conversion. Conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. Flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. The present study is an experimentally investigated of the performance of the solar coni...

PURPOSE To determine the composition and investigate the elastin fiber system in the juxtacanalicular tissue adjacent to and between collector channel orifices in normal human eyes. METHODS Normal human eyes (71.0 ± 8.6 years; mean ± SD; n = 4) were perfusion fixed at low (10 mm Hg) and high pressure (20 mm Hg) with 3% paraformaldehyde/0.1 M phosphate buffer. Frontal serial sections were cut ...
