Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...

A side channel attack is a means of security attacks that tries to restore secret information by analyzing side-information such as electromagnetic wave, heat, electric energy and running time are unintentionally emitted from computer system. The focuses on the cryptosystem specifically named “timing attack”. Timing relatively easy carry out, particularly threatening for tiny systems used in sm...

The multi-pad PICOSEC-Micromegas is an improved detector prototype with a segmented anode, consisting of 19 hexagonal pads. Detailed studies are performed data collected in muon beam over four representative We demonstrate that such device, scalable to larger area, provides excellent time resolution and detection efficiency. As expected from earlier single-cell device studies, we measure approx...

We propose an attentive device for synchronous groupware systems to mitigate information overload. The opportunity seeker device leverages the users’ natural alternation between doing individual work and attending to the group to dynamically manage the delivery timing and quantity of group awareness information that each user is exposed to. We describe how this device can be implemented in an e...

Introduction: Galvanic skin conductance (GSC) measurement has been used since the late 1880 [1] some times for “lie detectors”, but later in psychological research for reliable monitoring of arousal and changes in arousal due to applied stimuli [2]. The galvanic skin resistance (GSR) method relies on the fact, that arousal causes excretion by the perspiratory glands, which in turn increases the...

It has recently been shown that fair exchange, a security problem in distributed systems, can be reduced to a fault tolerance problem, namely a special form of distributed consensus. The reduction uses the concept of security modules which reduce the type and nature of adversarial behavior to two standard fault-assumptions: message omission and process crash. In this paper, we investigate the f...

In order to respond appropriately to environmental stimuli, organisms must integrate over time spatiotemporal signals that reflect object motion and self-movement. One possible mechanism to achieve this spatiotemporal transformation is to delay or lag neural responses. This paper reviews our recent modeling work testing the sufficiency of delayed responses in the nervous system in two different...

This paper describes the method used in the design of a 26 million transistors chip at BULL to verify the timing performance using the hierarchical timing analysis tool HiTas as well as the interactive path browser Xtas. Those tools have been designed at UPMC and are now commercialized by AVERTEC. The complexity is handled by partitioning the analysis according to the hierarchical partitioning ...

We discuss the di erent ways of de ning channel capacity for certain types of illicit communication channels. We also correct some errors from the literature, o er new proofs of some historical results, and give bounds for channel capacity. Special function techniques are employed to express the results in closed form. We conclude with examples.
