As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...

This thesis proposes architectures and algorithms for digital acquisition of parametric signals. It furthermore provides bounds for the performance of these systems in the presence of noise. Our simple acquisition circuitry and low sampling rate enable accurate parameter estimation to be achieved economically. In present practice, sampling and estimation are not integrated: the sampling device ...

The growth of Multi-Protocol Label Switching (MPLS) as the emerging choice for provisioning and managing core networks has placed significant emphasis on MPLS based recovery mechanisms. The present global protection frameworks require extensive involvement of Label Switching Routers (LSRs) in the protection framework. The LSRs are involved in failure propagation and maintenance of information r...

creation of urban identity is the important subject in architecture and urban design. so, this article foci’s on the creation of identity in urban context with participation approach in architecture and urban design. corporate architecture is an architectonic discipline which focuses on designing and constructing buildings, spaces or environments with the aim of meeting the needs of a business ...

This paper contributes to the studies of design activities in information systems development. It provides a case study of a large agile development project and focusses on how customers and users participated in agile development and design activities in practice. The investigated project utilized the agile method eXtreme Programming. Planning games, user stories and story cards, working softw...

Software engineering is a practical discipline, which requires competencies to develop economical and feasible solutions. Undergraduate students must be educated and trained to perform the roles required for software development in order to create that kind of solutions. Practice and training in real world are important factors to achieve the required level of competencies. Collaboration betwee...

Cloud computing is a style of computing which is formed from the aggregation and development of technologies such as grid computing distributed computing, parallel computing and service-oriented architecture. And its aim is to provide computing, communication and storage resources in a safe environment based on service, as fast as possible, which is virtually provided via Internet platform. Con...

The presented project aims at the examination of the relation of the deaf and hard of hearing people with the new technologies in Greece. The research was conducted through the construction and delivery of an online questionnaire to the members of two deaf organisations in Athens and refers to the motives, for the use of the internet services by deaf people. Particularly, the subject of this pr...

Using high-strength steels for pressure shafts and tunnel liners and taking into account significant rock mass participation allows the design of comparatively thin steel liners in hydropower projects. Nevertheless, during emptying of waterways, these steel linings may be endangered by buckling. Compared with traditional measures such as increased steel liner thickness and stiffeners, pressure ...
