In the framework of the ESS activity in progress at INFN-LASA, we are designing and developing 704.42 MHz Medium (β=0.67) and High (β=0.86) beta prototype cavities plug compatible with the ESS cryomodule design. The cells of one Medium and one High beta cavity are fabricated with high quality CBMM Large Grain Niobium (480 mm dia. Ingot, RRR=300, sliced by Heraeus) while a Medium beta cavity is ...

Purpose: The aim of this study was to design and validate a high school technological competency curriculum model. Methodology: This study had an integrated strategy. To answer the questions, the research was conducted in four phases. The first phase was conducted with a qualitative approach and the other phases were conducted with a quantitative approach. In the first phase of this research, ...

This study aims to explain and elaborate a new model for the business environmental hostility in small and medium enterprises in the science and technology park in Kermanshah (Iran). The research method is a mixed method. Content analysis was used in the qualitative part, and a confirmatory factor analysis was used in the quantitative section. In the qualitative section for the environmental ho...

background: extensive full-thickness burns require replacement of both epidermis and dermis. in designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. methods: in the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...

Abstract The article considers the issue of modern engineering training with use CDIO-approach (Conceiving, Designing, Implementing, and Operation) aimed to balance goals practice teaching at higher technical institutions. Modern pedagogical technologies innovative methods enable create such an education medium where students will obtain profound knowledge, manage process designing exploiting n...

Designing navigable electronic environments usually involve looking at navigation from various perspectives. This paper describes some of the views that have to be considered when designing for navigation in electronic worlds with special reference made to shared spaces. Current ongoing projects involving issues related to navigation in shared electronic spaces are also briefly described. These...

The design of a physical space can and should take advantage of information architecture (IA) deliverables, in particular when designing an integrated model of IA. The user must be able to easily-consult [...] technology-dependent environments, e.g. digital medium or printed paper catalogue, in line with the information flow conveyed through the website. Conveying the relevance of information t...

In the paper we examine one of the issues in designing, specifying, implementing and formally verifying a small operating system kernel — how to provide a productive and iterative development methodology for both operating system developers and formal methods practitioners. We espouse the use of functional programming languages as a medium for prototyping that is readily amenable to formalisati...

We describe a methodology for designing the optimal gain profiles for gain-based, tunable, broadband, slow-light pulse delay devices based on stimulated Brillouin scattering. Optimal gain profiles are obtained under system constraints such as distortion, total pump power, and maximum gain. The delay performance of three candidate systems: Gaussian noise pump broadened (GNPB), optimal gain-only,...

XML itself does not support hypermedia, but the XLink standard has been defined to make XML usable for hypermedia. One of XLinks most interesting features is its support for external links and linkbases, which makes it possible to create links between resources without having to change the resources. In order to use these links, user agents must access linkbases and query them for relevant link...
