Blow flies are among the most important insects in forensic entomology casework. Identification of blow fly species can be a time consuming and difficult task, especially at their early development stages. Present DNA-based technologies provide a promising identification method for these forensically important calliphorids. The cytochrome oxidase subunit I(More)
A method to obtain the local heat transfer coefficients of carbon dioxide at supercritical pressures in vertical multi-port mini-channels and in a vertical small tube under cooling conditions was presented through the combination of experiments and numerical simulation in this paper. The CFD code FLUENT 6.1 was used to simulate the convection heat transfer(More)

Zigzag paths in sports ball trajectories are exceptional events. They have been reported in baseball (fromwhere theword knuckleball comes from), in volleyball and in soccer. Such trajectories are associatedwith intermittent breaking of the lateral symmetry in the surrounding flow. The different scenarios proposed in the literature (such as the effect of(More)
The stable operation of a system is restricted by the intrinsic characteristics, namely harmonious matching among and between structure parameters and operation parameters. In this paper, we put forward an analysis method of the dynamic stability of the refrigeration system based on the First Approximation Theory of Lyapunov Stability Theorem and the(More)
Based on shadowgraph technique, a visual research for an ejector in transcritical CO2 refrigeration cycle has been conducted. The mixing process and the changes of the flow structure in suction chamber was recorded. A visualization test platform with rectangular ejector was builted to collect experiment data about the performance of ejector. And images of(More)
An adaptive genetic algorithm of service selection in pervasive computing is presented in this paper. By means of matrix encoding, this algorithm carries out selection, crossover and mutation operations of genetic algorithm, with matrix as individual chromosome and matrix array as gene. Based on the elitism selection strategy and adaptive strategy, this(More)
