Geotechnical centrifuges can simulate the behavior of soil material, with a high accuracy. One of the main aspects of centrifuge tests is sample monitoring during the test. Picture transfer is a useful way of gaining data from the sample. In this study, a vertical nailed slope was tested. Its side wall is meshed by target points and lines. The displacements of the points and deformation of the target lines are continually monitored. By triangulation of the points with an assumption of a linear displacement field, the magnitude of shear strain was calculated. Considering the peak points of strain curve in a longitudinal profile of the side wall, the position of the failure surface (zone) can be determined. Considering the deformation of line targets, the calculated surface is compared with reality. The results show good agreements.
Due to large computation cost and low accuracy of traditional angel measurement in single-beam mechanical scanning radar, a new application of monopulse techniques is proposed. First of all, this paper introduces the ...

A characteristic of the new criteria for TAC/ABET accreditation is the assessment requirements. This part of the new criteria seems daunting to many people. However, assessment of the outcomes of education has always been a part of the university experience through the use of grading. The conventional criteria evaluated this assessment by requiring the school to capture graded student work and create course books with these captured samples in them. By looking at the assessments of the students done by the teachers during a course, an evaluator could come to some conclusions about the quality of teaching being done. The old method is adequate for capturing the outcomes that are directly related to what is now called Criterion 1 Subsection A. The new criteria are more specific about what should be measured and this new specificity is captured in Criterion 1 Subsections B-K Criteria. The new criteria also require assessment data to be presented in a new form, summarized and collated according to the program outcomes;i.e., the new criteria require alignment between the stated outcomes of a program and the curriculum being taught. It is these outcomes that require assessment, and not the sometimes nebulous content of a course that may or may not directly contribute to them. This paper documents a method to begin capturing assessment of our program outcomes by using WebCT on-line testing.

The underground copper cable wire is filled and pressurized with a filling compound in order to stop water from entering the cable. The fault mostly appears on the closure of the joint. Normally, the plastic shield wrapped inside will be the first to retard the water after first coming into the cable. The connector can protect the water absorption for a period of time;however, the water can make its way to the inner core of the joint, thus damaging the cable. The research was meant to design a detector which will be installed inside the closure and warn the maintenance technicians of the possible adversity. sensor to detect water or liquid.

Two aspects of the dispersion of pollutants from aircraft are reviewed. The first is the dispersal of aircraft exhaust emissions in the vicinity of airports;the second is the dispersal of exhaust trails in the upper atmosphere. Techniques available for modeling this dispersal and how they might be applied to the airport problem are discussed. Field studies of airport pollution are then reviewed to assess current pollutant levels around airports and the aircraft's contribution to those levels. The possibility of contrail formation from jet emissions at high altitude is then considered and the effect of uncertainties in the trail mixing processes evaluated.
