Characterization of I/O channels, signal quality, and supply noise in 3-D packaged systems is very challenging due to the small footprint and complex 3-D interaction. This paper presents several enabling techniques to allow on-chip signal and power integrity characterization for the 3-D packaged systems. They provide comprehensive in-situ characterization capabilities for measuring overall link...

Adaptive Packet Filters (APFs) are motivated by the proliferation of distributed servers and the lack of Quality-of-Service (QoS) management solutions for them. APFs merge packet-filtering and server load monitoring into a novel load-sensitive packet-filtering abstraction for overload protection and QoS differentiation. They integrate well into network protocol stacks and firewalls, scale to la...

Power costs are very significant for data centers. To maximally utilize the provisioned power capacity, data centers often employ over-subscription, that is, the sum of peak consumptions of individual servers may be greater than the provisioned capacity. Power budgeting methods are employed to ensure that actual consumption never exceeds capacity. However, current power budgeting methods enforc...

This paper describes a pulsed electron gun that can be used as an FEL, as an injector for electron linear accelerators or for rf power generation. It comprises a 1 to 5 MeV, 1 to 2 ns pulsed power supply feeding a single diode, photoexcited acceleration gap. Beam quality of a ~ 1nC charge in ~ 1 GV/m field was studied. Computations of the beam parameters as a function of electrode configuration...

To meet the requirements of resource-limited video sensors, low-complexity video encoding technique is highly desired. In this paper, we propose a lowcomplexity power-scalable multi-view distributed video encoding scheme by using the correlations among video frames from adjacent video sensor nodes via robust media hashing extracted at encoder and using the global motion parameters estimated and...

The article discusses the issues of creating contactless switching devices for automatic quality control and operation modes power supply systems, using developed thyristor voltage relays, characterized by high reliability speed, combining a sensitive system powerful final controlling element. Schemes with operating principles experimental characteristics are given. It is proposed to use it aut...

Continued population growth, coupled with increased per capita consumption of resources, poses a challenge to the quality of life of current and future generations. We cannot expect to meet the future needs of society simply by extending existing infrastructures. The necessary transformation can be enabled by a sustainable IT ecosystem made up of billions of service-oriented client devices and ...
