The Low-Emittance Transport (LET) region of a linear collider includes all of the beamlines between the exit of the main damping ring and the interaction point. Generically, the LET includes the bunch compressor, main linac, and beam delivery sections of the linear collider. The principal luminosity requirements of the LET are: preservation of the small emittances generated by the main damping ...

In the developed world a very small proportion of work tasks are done using paper and pen and yet most high-stakes assessment in schools continue to use this primitive technology. While employers and community leaders call for schools to produce students with 21 Century skills and deep conceptual understanding of content the main driver of curriculum and pedagogy, assessment, continues to focus...

For the sake of simplicity in resource sharing, Grid services only expose a function access interface to users. However, some Grid users want to know more about the performance of services in planning phase. Problem emerges since the Grid simply has no means in obtaining how well the system will cope with user demands. Current Grid infrastructures do not integrate adequate performance assessmen...

Hamming codes can detect up to two simultaneous bit errors, and correct single-bit errors; thus, reliable communication is possible when the Hamming distance between the transmitted and received bit patterns is less than or equal to one. By contrast, the simple parity code cannot correct errors, and can only detect an odd number of errors. We will analyze hamming code with simulations (using Ha...

The ability to distinguish between objects is the fundamental to learning and intelligent behavior in general. The difference between two things is the information we seek; the processed information is actually the base for the knowledge. Automatic extraction of knowledge has been in interest ever since the advent of computing, and has received a wide attention with the successes of data mining...

We explore the utility of functional Near Infra Red (fNIR) technology in providing both empirical support and a basis for assessing and predicting dynamic changes in cognitive workload within the theoretical context of computational cognitive modeling (CCM). CCM has had many successes and in recent years has expanded from a tool for basic research to one that can tackle more complex real-world ...

Swimming performance tests of fish have been integral to studies of muscle energetics, swimming mechanics, gas exchange, cardiac physiology, disease, pollution, hypoxia and temperature. This paper describes a flexible protocol to assess fish swimming performance using equipment in which water velocity can be controlled. The protocol involves one to several stepped increases in flow speed that a...

Laboratory activities are very important in engineering education. Performance assessment of students’ laboratory work is time consuming and an ongoing challenge for teachers. Laboratory work performance assessment is traditionally done by the teacher grading students’ written report of the laboratory activity, despite the fact that the report is often 'doctored'. Assessment of laboratory work ...

The challenge that is often faced by companies how to find solutions can be used evaluate the performance of their employees. purpose this study design a service-based appraisal system with ticket support employee appraisals in company. By using assessment system, carried out objectively based on what employees have done, possible because parts and roles company been mapped, where each role has...

Few jurisdictions have a robust common approach to assessing the quantitative and qualitative dimensions of physician performance. In this article, we examine the need for 360-degree physician performance assessment and review the literature supporting comprehensive physician assessment. An evidence-based, "best practice" approach to the development of a 360-degree physician performance assessm...
