Software reliability is closely influenced by the creation, manifestation and impact of software faults. Consequently, software reliability can be improved by treating software faults properly, using techniques of fault tolerance, fault removal, and fault prediction. Fault tolerance techniques achieve the design for reliability, fault removal techniques achieve the testing for reliability, and ...

grid computing is an emerging computing paradigm that will have significant impact on the next generation information infrastructure. due to the largeness and complexity of grid system, its quality of service, performance and reliability are difficult to model, analyze and evaluate. this paper proposes a virtual tree-structured model of the grid service. this model simplifies the physical struc...

Along with the social development, CNC machine tool is becoming more and more complex in its structure, while its reliability is becoming more and more important in the market. Since CNC machine tool functional reliability is more significant than its mechanical structural reliability, and the whole machine tool system’s functional reliability is guaranteed by every meta-action’s reliability, a...

Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...

BACKGROUND Psychosocial evaluation is an important part of the live organ donor evaluation process, yet it is not standardized across institutions, and although tools exist for the psychosocial evaluation of organ recipients, none exist to assess donors. OBJECTIVE We set out to develop a semistructured psychosocial evaluation tool (the Live Donor Assessment Tool, LDAT) to assess potential liv...

Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...

BACKGROUND The outcome of assessments is determined by the standard-setting method used. There is a wide range of standard-setting methods and the two used most extensively in undergraduate medical education in the UK are the norm-reference and the criterion-reference methods. The aims of the study were to compare these two standard-setting methods for a multiple-choice question examination and...

The Accreditation Board for Engineering and Technology in 2000 revised accreditation criteria to require program assessment according to eleven outcomes that all require critical thinking skills. Critical thinking can be incorporated into engineering classes in a variety of ways including writing assignments, active learning strategies, project-based design experiences, and course redesign. Cle...

BACKGROUND This study tried to develop an Asian Stroke Disability Scale (ASDS) and compared its interrater reliability with modified Rankin Scale (mRS) and Barthel Index (BI). METHODS Three items including self-care, mobility, and daily activities were selected as variables for development of the ASDS. The variables were provisionally graded on a 2- to 4-point scale based on the importance of...
