Extensive single event effects tests were performed on a new generation, the R6 process, of radiation-hardened 600-volt and 250-volt power metal-oxide semiconductor field-effect transistors (MOSFETs) from international rectifier using two different ions (krypton and xenon) at many different beam energies, Bragg peak positions, and drain and gate biases.(More)
One hundred and thirty eight unselected hemodialysis patients were screened for allergic symptoms, atopy, total IgE, eosinophil count, specific IgE against ethylene oxyde (ETO), formaldehyde (FA) and isocyanates (Iso) and delayed hypersensitivity to formaldehyde. Six patients demonstrated hypersensitivity to formaldehyde. Six patients demonstrated(More)
This paper discusses issues concerning single-event burnout (SEB) and single-event gate rupture (SEGR); explains and provides a basic overview of the preferred test conditions and procedures that would yield the most meaningful test results in evaluating power MOSFETs’ SEB susceptibilities, describes how to correctly identify SEB and SEGR failure modes to(More)
A [55,16,191 binary Goppa code is used to construct [57,17,171, [58,17,181, [59,17,191, and [a, 17,201 codes. The first two codes have smaller redundancy than previously known codes (linear or nonlinear) of the same length and minimum distance, while the last two codes have parameters previously attained only by nonlinear codes.

Life cycle costing is an important consideration for new concrete structures. It is also an integral part of asset management and in achieving sustainable construction. Cost effectiveness is the key driver. This paper presents an overall approach to formulate a strategy for protection of reinforced concrete structures against steel corrosion. The objectives(More)
