Presented in this paper is a study of the capacity evaluation of various multiuser MIMO schemes in cellular environments. The throughputs per user of the generalized zero-forcing with rank adaptation and vector perturbation schemes are compared with the capacity bound of the Gaussian MIMO broadcast channel, obtained by dirty paper coding under proportional fairness scheduling. The average cell ...

Garbled circuits is a cryptographic technique, which has been used among other things for the construction of two and three-party secure computation, private function evaluation and secure outsourcing. Garbling schemes is a primitive which formalizes the syntax and security properties of garbled circuits. We de€ne a generalization of garbling schemes called reactive garbling schemes. We conside...

Wireless sensor networks (WSNs) are a comparatively new revolutionary technology that has the potential to revolutionize how we live together with present system. To enhance data archiving, WSNs frequently used in scientific studies. Many applications have proved value of wired sensors; however, they prone wire cutting or damage. While preventing tangles and damage, wireless provide autonomous ...

We explore few-shot learning (FSL) for relation classification (RC). Focusing on the realistic scenario of FSL, in which a test instance might not belong to any target categories (none-of-the-above, [NOTA]), we first revisit recent popular dataset structure pointing out its unrealistic data distribution. To remedy this, propose novel methodology deriving more from available datasets supervised ...

Visual specification of software is gaining popularity, but its usage is restricted by the lack of precise semantics of visual languages. In the present work, precise semantics of visual languages is defined. Three kinds of deep semantics of schemes are presented as different ways of usage of attribute models of schemes. Attribute models of a wide class of schemes are defined and higher-order a...
