The reliability of a power converter can be improved using a well-dimensioned cold plate. At this aim it is necessary to realize a state of the art cold plate by means of thermal-fluid dynamic numerical analysis and ad-hoc designed experimental test bench. Features and metrological characterization of test bench for cold plate design and verification will be discussed in this paper.
Devices used in future experiments at LHC will be called to work in very hostile environment. Power supply is a key aspects in this scenario and new converter will be re-designed in order to meet the future requirements. In this paper a main DC-DC power converter, developed by authors in the framework of the APOLLO R&D project, has been proposed and the experimental activity devoted to its characterization...
Nowadays the world energy infrastructure is subjected to a progressive transformation. In fact it is already possible to notice the growing number of distributed small generation units, based on different technologies, directly connected to the power grid. At present the energy that can be produced by the sun and wind seem to be the most promising renewable energy sources. The use of the solar energy...
In recent years, radio frequency identification (RFID) systems have been increasingly used in critical domains such as medical field or real-time processing domains. Although important efforts have been made to make this technology more reliable and fault-tolerant, more research is needed to meet the increasing dependability requirements. In this article, we propose a dependability approach consisting...
The constant evolution of technologies involves a large amount of problems during and after Flash memory manufacturing. In this context, manufacturers must develop methods and design solutions to improve reliability especially for automotive applications. For this purpose, ECC and BISR are probably the most efficient concepts to enhance memory reliability. However, such techniques are limited to correct...
This work presents SAPOTI (Dependable TCP/IP application servers - in portuguese: servidores de aPlicacoes cOnfiaveis Tcp/Ip), a distributed tool that guarantees the availability of TCP/IP application servers, in particular of Web servers. The tool is based on the SNMP framework and is executed on a group of Web servers running on a set of hosts that are monitored by a dependable distributed network...
The test executivepsilas primary purpose is to control the flow of testing on a given piece of automated test equipment. It accomplishes this by loading and executing a test programpsilas compiled executable code. Code execution enables the test executive to control the instruments, make decisions and direct the testing in accordance with the instructions contained in the test program. In addition...
