Security is an extremely important issue in the development of distributed systems. This applies in particular to Web-based systems, which communicate over an open network. Failures of security mechanisms may cause very high damage with financial and legal implications. Security concerns, both on the part of enterprises and consumers, are one of the major reasons why new technologies such as E-...

A vibration isolation module with zero-power magnetic suspension is developed to retrofit a passive vibration isolation system to improve the performance against direct disturbance. In the module, the zero-power magnetic suspension mechanism is connected in series with a normal spring through a middle mass. This structure can generate zero compliance to direct disturbance while the transmitted ...

I have done my master thesis project on autonomic computing at Amadeus, a major provider of online travel booking systems. Autonomic computing is an effort to decrease the cost of owning an IT infrastructure through self-management of systems. The approach is to develop an infrastructure for an external autonomic manager which can interact with legacy systems. This infrastructure is implemented...

Abstract Nowadays, retrofitting-damaged buildings is an important challenge for engineers. Finding the optimal placement of Viscous Dampers (VDs) between adjacent structures prone to earthquake-induced pounding can help designers implement VDs with optimizing cost construction and achieving higher performance levels both structures. In this research, linear nonlinear 3-story, 5-story, 9-story S...

Eco-certification schemes are usually launched with various incentives provided by local governments to facilitate green building development and energy retrofits. A number of barriers retrofitting have been identified in previous literature, while the eco-certification existing buildings under-researched. Drawing on a set data retrievable from BEAM Society other sources, we carried out an anal...

Electric retrofitting (e-retrofitting) is a viable option for accelerating the renewal of heavy-duty vehicle fleets to reduce related emissions. We introduce simulation-based assessment e-retrofitting strategies vehicles. Our simulation tool, an electric fleet toolbox, comprises three modules, namely driving cycles, dynamics, and profiles. The first allows creation realistic cycles based on GPS...
