The EPC Class-1 Generation-2 (Gen2 for short) is a Radio Frequency IDentification (RFID) technology that is gaining a prominent place in several domains. However, the Gen2 standard lacks of verifiable security functionalities. Eavesdropping attacks can, for instance, affect the security of applications based on the Gen2 technology. To address this problem, RFID tags must be equipped with a robu...

GANs excel at learning high dimensional distributions, but they can update generator parameters in directions that do not correspond to the steepest descent direction of the objective. Prominent examples of problematic update directions include those used in both Goodfellow’s original GAN and the WGAN-GP. To formally describe an optimal update direction, we introduce a theoretical framework whi...

We consider hermitian dissipative mappings δ which are densely defined in unital C∗-algebras A. The identity element in A is also in the domain of δ. Completely dissipative maps δ are defined by the requirement that the induced maps, (aij) → (δ(aij)), are dissipative on the n by n complex matrices over A for all n. We establish the existence of different types of maximal extensions of completel...

In this paper for the first time a precise theoretical analysis of efficiencies and power densities for nano-scaled thermionic vacuum gap devices is presented. Plane electrodes with nano-gaps will be treated first. With nonplanar electrodes (nanotips) enhanced electron field emission occurs, giving rise to new design options. The theories of field and thermionic emission are combined by calcula...

A key objective of multidimensional dataset analysis is to reveal patterns of interest to users, but can be difficult to conduct due to the challenges of both presenting and navigating large datasets. This work explores how initial summarizations of multidimensional datasets can be generated (designed to reduce the number of data points which would need to be displayed), using summarization pol...

Getting polymorphism and effects such as mutation to live together in the same language is a tale worth telling, under the recurring refrain of copying vs. sharing. We add new stanzas to the tale, about the ordeal to generate code with polymorphism and effects, and be sure it type-checks. Generating well-typed–by–construction polymorphic let-expressions is impossible in the Hindley-Milner type ...

a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...

we investigate the stability of generalizedderivations on banach algebras with a bounded central approximateidentity. we show that every approximate generalized derivation inthe sense of rassias, is an exact generalized derivation. also thestability problem of generalized derivations on the faithful banachalgebras is investigated.

in the restructured environment of electricity market, firstly the generating companies and the customers are looking for maximizing their profit and secondly independent system operator is looking for the stability of the power network and maximizing social welfare. in this paper, a one way auction in the electricity market for the generator companies is considered in both perfect and imperfec...

Let $mathfrak{A}$ be an algebra. A linear mapping $delta:mathfrak{A}tomathfrak{A}$ is called a textit{derivation} if $delta(ab)=delta(a)b+adelta(b)$ for each $a,binmathfrak{A}$. Given two derivations $delta$ and $delta'$ on a $C^*$-algebra $mathfrak A$, we prove that there exists a derivation $Delta$ on $mathfrak A$ such that $deltadelta'=Delta^2$ if and only if either $delta'=0$ or $delta=sdel...
