Finite Difference Time Domain (FDTD) is applied to study the characteristics of electromagnetic interference for power plane-battery management system (PP-BMS) enclosure, for modeling the coupling of an incident electromagnetic pulse (EMP) with a conducting wire through a BMS enclosure and aperture on it. Simulation and analysis are done by radius of the wires, incidence angles of EMP in the co...

The design of future large optical telescopes must take into account the wind-induced vibration of the telescope structure that is caused by large-scale flow structures and turbulence inside the telescope enclosure when the aperture in the enclosure dome is open. However, estimating the resulting degradation in image quality is difficult due to our relatively poor understanding of the flow insi...

A new type of range searching problem, called the partial enclosure range searching problem, is introduced in this paper. Given a set of geometric objects S and a query region Q, our goal is to identify those objects in S which intersect the query region Q by at least a fixed proportion of their original size. Two variations of this problem are studied. In the first variation the objects in S a...

More than 60% of accidents in Iran occur within 30 kilometers of cities entrance roads. Therefore the number of accidents per kilometer in these regions, in contrast to the other parts of roads is very considerable. The city of Tehran, as the capital of Iran, is the cross point of major arterials of passenger and freight transportation. Thus the evaluation of road safety, entering and exiting t...

Literature about entropy generation analysis of a wavy enclosure is scare. In this paper. a FORTRAN cod using an explicit finite-volume method was provided for estimating the entropy production due to the natural convection heat transfer in a cosine wavy absorber solar collector. The volumetric entropy generation terms both the heat transfer term and the friction term were straightly calculated...

The enclosure, lighting and equipment of existing residential buildings have been determined. Therefore, the occupancy behavior has a great influence on energy consumption air conditioning in buildings. In this paper, building was selected as research object, long- term sorted out. Then through calculation correction with actual data, characteristics which are related to personnel timetable, co...

A simple technique for the measurement of the shielding efficiency of a symmetric enclosure is presented. It allows measurements in the symmetry plane of the enclosure without the need of introducing cables which could interfere with the results. Comparisons with simulation results are shown. Limits of the concept of shielding efficiency of enclosures at high frequencies are also briefly discus...

in this paper, shielding effectiveness (se) of a perforated enclosure with imperfectly conducting walls is evaluated. to this end, first, an accurate numerical technique based on method of moments (mom) ispresented. in this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. then, the impedance boundary condition on the imperfectly conductin...
