In this paper, we study the problem of multi-robot perimeter patrol in adversarial environments, under uncertainty. In this problem, the robots patrol around a closed area, where their goal is to patrol in a way that maximizes their chances of detecting an adversary trying to penetrate into the area. Uncertainties may rise in different aspects in this domain, and herein our focus is twofold. Fi...

– Until recently it has been believed that the superconductivity in Sr2RuO4 is described by p-wave pairing. However, both the recent specific heat and the magnetic penetration depth measurements on the purest single crystals of Sr2RuO4 appear to be explained more consistently in terms of f-wave superconductivity. In order to further this hypothesis, we study theoretically the thermodynamics and...

alzheimer's disease is the most common degenerative disease of brain. nowadays, the most common treatment being used to slow down disease progression, include donepezil , rivastigmine and galantamine, which all of them act as inhibitors of acetyl cholinesterase. general purpose of our study was to show effects of treatment with donepezil and rivastigmine, as two drugs that commonly used for tre...

Penetration testing is one of the oldest methods for assessing the security of a computer system. The idea behind penetration testing methodologies is that the penetration tester should follow a pre-scripted format during test as dictated by the methodology. A penetration testing methodology was proposed in this research. It is also important to consider a policy that should be followed by both...

Penetration testing is widely used to help ensure the security of web applications. Using penetration testing, testers discover vulnerabilities by simulating attacks on a target web application. To do this efficiently, testers rely on automated techniques that gather input vector information about the target web application and analyze the application’s responses to determine whether an attack ...

Recently, Liaw et al. proposed a hash based electronic traveler’s check system. They claimed that their scheme is secure. However, after analyses, we found that their scheme is vulnerable to key compromise impersonation and parallel session attack. Further, we will improve their scheme to avoid such an attack.

We describe two efficient methods of estimating the fluid permeability of standard models of porous media by using the statistics of continuous Brownian motion paths that initiate outside a sample and terminate on contacting the porous sample. The first method associates the ‘‘penetration depth’’ with a specific property of the Brownian paths, then uses the standard relation between penetration...

This paper studies the impacts of vehicular communications on efficiency of traffic in urban areas. We consider a Green Light Optimized Speed Advisory (GLOSA) application implementation in a typical reference area, and present the results of its performance analysis using an integrated cooperative ITS simulation platform. In addition, we study route alternation using Vehicle to Infrastructure (...

Cybersecurity classes should be focused on building practical skills along with the development of the open mindset that is essential to tackle the dynamic cybersecurity landscape. Unfortunately, traditional lecture-style teaching is a poor match for this task. Peer instruction is a non-traditional, active learning approach that has proven to be effective in many fundamental courses of computer...
