The Mathematical Model

The power and brake performance of wheeled construction machinery are separately detected on different test equipment in present chassis detection line. A new method is put forward in the veiw of high cost, large area occupied and low treatment efficiency of the traditional line. A DC dynamometer is provided as the power absorbing device and the reverse drag device to combine the two separate platforms in the proposed method, and the mathematical model of DC dynamometer is built based on the principle of chassis performance test. The parameter of dynamometer is determined by calculating, and power and brake detection integration of the wheeled construction machinery is achieved on the integrated test platform.

New Method

Abstract We define jet transition values for the anti-$$k_{\bot }$$k⊥ algorithm for both hadron and $$e^+e^-$$e+e- colliders. We show how these transition values can be computed and how they can be used to improve the performance of clusterization when jet resolution parameters are varied over a larger set of values. Finally we present a simple performance test to illustrate the behavior of the new method compared to the original one.

Water Wheel

Waterwheel has been developed over two millennia to be efficient hydraulic machine but have weaknesses due to his inability to increase the torque although the flow of water has been increased - because the efficiency of this water wheel is only dependent on the volume of buckets and gravitational those are always constant. In this study demonstrated a new method to improve the torque of overshot waterwheel (OWW) by recapturing overflow of water from the buckets and the excess flow from the channel to be converted into kinetic energy through the nozzle and then squirt against to the curve vane in the buckets by using hydraulic ram pump system. The result of performance test proved that OKDN using hydraulics ram able to improve their efficiency more than conventional overshot wheel.

Accurately predicting software bugs is one of software engineering’s great tasks. Current bug prediction algorithm take one aspect of software for granted, while neglecting the other aspect. This paper extracted static and dynamic features from software, which were used to predict bugs using relevance vector machine algorithm. Experimental results show that the new method outperforms others to a great extent.

Specific Orientation

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.

Noise Test

The purpose of this article is to propose 4 dimensions for consideration in hearing aid fittings and 4 tests to evaluate those dimensions. The 4 dimensions and tests are (a) working memory, evaluated by the Revised Speech Perception in Noise test (Bilger, Nuetzel, & Rabinowitz, 1984); (b) performance in noise, evaluated by the Quick Speech in Noise test (QSIN; Killion, Niquette, Gudmundsen, Revit, & Banerjee, 2004); (c) acceptance of noise, evaluated by the Acceptable Noise Level test (ANL; Nabelek, Tucker, & Letowski, 1991); and (d) performance versus perception, evaluated by the Perceptual–Performance test (PPT; Saunders & Cienkowski, 2002). The authors discuss the 4 dimensions and tests in the context of improving the quality of hearing aid fittings.
