A general evaluation methodology development and application process (EMDAP) paradigm is described for the resolution of\r\nsevere accident safety issues. For the broader objective of complete and comprehensive design validation, severe accident safety\r\nissues are resolved by demonstrating comprehensive severe-accident-related engineering through applicable testing programs,\r\nprocess studies demonstrating certain deterministic elements, probabilistic risk assessment, and severe accident management\r\nguidelines. The basic framework described in this paper extends the top-down, bottom-up strategy described in the U.S Nuclear\r\nRegulatory Commission Regulatory Guide 1.203 to severe accident evaluations addressing U.S. NRC expectation for plant design\r\ncertification applications....
Moving averages are one of the most popular and easy-to-use tools available to a technical analyst, and they also\r\nform the building blocks for many other technical indicators and overlays. Building a moving average (MA) model\r\nneeds determining four factors of (1) approach of issuing signals, (2) technique of calculating MA, (3) length of MA,\r\nand (4) band. After a literature review of technical analysis (TA) from the perspective of MA and some discussions\r\nabout MA as a TA, this paper is structured to highlight the effects that each of the first three factors has on\r\nperformance of MA as a TA. The results that based on some experiments with real data support the fact that\r\ndeciding about the first and second factors is not much critical, and more attention should be paid to other factors....
In the frame of the CEA, EDF, and AREVA coordinated research program launched in 2007 for the development of Generation\r\nIV sodium-cooled fast reactors (SFRs), the improvement of in-service inspection and repair (ISI&R) capabilities was identified as\r\na major issue. Within the French-associated multiannual SFR research program, the periodic examination and repair are looked\r\nat through the following main R&D axes: (i) improvement of the primary system conceptual design in order to ease periodic\r\nexamination and repair, (ii) development of inspection techniques (periodic inspection tools and associated simulation), (iii)\r\naccessibility and associated robotics, and (iv) development and validation of repair processes. Associated needs are being defined\r\nthrough an iterative method between designers and inspection specialists: adaptation of the SFR design to ISI&R requirements,\r\nvalidation of the ultrasonic transducers, of associated ultrasonic nondestructive examination techniques, of laser repair processes,\r\nof associated robotic equipment. International collaboration is also running for some specific items such as ultrasonic visualization\r\nunder liquid sodium....
The present article makes a short introduction in the legal and practical aspects of the computer\r\nscience investigation. It is well known the fact that a computer can represent an invaluable source of pieces of\r\nevidence, both in the civil cases as well as in the criminal ones because it contains data regarding the activities\r\ncarried out by the suspect with the help of the IT equipment....
Recent research reveals a gap in determining the effect of problem-based learning (PBL) on students� critical thinking ability.\r\nExisting evidences from previous research have been equivocal to be deemed conclusive, especially in across multiple educational\r\ndisciplines. This paper investigates the effect of PBL on students� critical thinking ability, as compared to conventional approach.\r\nThe study employed an experimental pretest and posttest with control group design. The participants were 53 undergraduate\r\nstudents in electrical engineering course, who attended Electrical Technology Module (ET101) in their first semester. Participants\r\ncompleted the pretest and posttests of the translated version of the Cornell Critical Thinking Test Specimen set. The results\r\nsuggested that students� critical thinking ability in the PBL group had not been significantly different from their counterparts in the\r\nconventional approach group. This paper further discusses the implication of problem-based learning in engineering education....
