Recently we presented a method for modeling a quantum system to a bath that explicitly correlates the system with the individual bath modes. We do this through representation of the bath by locally propagating Gaussians (LPG), which change in position and momentum but remain Gaussian in form. The explicit correlation of the system to the bath modes enters through the simultaneous use of a di†er...

The ambient index and temperature effects on the spectral profiles of two sets of long period gratings (LPGs) of different periods were investigated. The shorter period LPGs were found to be more sensitive than the longer period LPGs over identical ambient index ranges but less sensitive over identical temperature ranges. The coupling wavelength shifts due to temperature are also seen to be lin...

BACKGROUND Preoperative histologic grading was used to decide the length of the margin of resection in adenocarcinoma of colon and rectum. OBJECTIVES The aim of the present study was to determine the accuracy of preoperative histologic grading by comparison with postoperative histologic grading. MATERIAL AND METHOD Preoperative and postoperative histologic grading of patients with adenocarc...

For visual grading experiments, which are an easy and increasingly popular way of studying image quality, hitherto used data analysis methods are often inadequate. Visual grading analysis makes assumptions that are not statistically appropriate for ordinal data, and visual grading characteristic curves are difficult to apply in more complex experimental designs. The approach proposed in this pa...

This well-designed site has links that cover multiple aspects of testing and grading from a basic introduction to testing and measurement to such specific issues as improving multiple choice tests and advice on writing and grading essay questions. Assessment Terminology: A Glossary of Useful Terms (New Horizons for Learning). This site contains clear definitions of assessment terms from account...

Computer grading of hardwood lumber promises to avoid regrading of the same lumber because of disagreements between the buyer and the seller. However, the first generation of computer programs for hardwood lumber grading simplify the process by modeling defects on the board as rectangles. This speeds up the grading process but can inadvertently put a board into a lower grade because rectangular...

AIMS To assess the cost-effectiveness of an improved automated grading algorithm for diabetic retinopathy against a previously described algorithm, and in comparison with manual grading. METHODS Efficacy of the alternative algorithms was assessed using a reference graded set of images from three screening centres in Scotland (1253 cases with observable/referable retinopathy and 6333 individua...

Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...

A large amount of the role of the land surveyor, land registries and land information systems is concerned with building and maintaining a land administration infrastructure where one of its primary tasks is to support the operation of an efficient and effective land market. This includes cadastral surveys to identify and subdivide land, land registry systems to support simple land trading (buy...

Land Information System is a tool for legal, administrative and economic decision making as well as an aid for planning and development. The present land administration system in Pakistan is entirely based on paper land records and maps lacking standards with outdated information stored at different administrative levels. Such practice restricts the usefulness of reliable and quality land infor...
