a quantum chemical investigation was carried out to study the properties of intermolecular f•••f, br•••br and br•••o interactions in crystalline 1-bromo-2,3,5,6-tetrafluoro-nitrobenzene (bfnb). this system was selected to mimic the halogen-halogen as well as halogen bonding interactions found within crystal structures as well as within biological systems. we found that fluorine atoms have weak ...

Wireless ad-hoc networks are based on shared medium technology where the nodes arrange access to the medium in a distributed way independent of their current traffic demand. This has the inherent drawback that a node that serves as a relay node for transmissions of multiple neighboring nodes is prone to become a performance “bottleneck”. In the present paper such a bottleneck node is modeled vi...

This paper formulates a problem of embedded real-time system re-engineering and presents a systematic solution. Embedded real-time system re-engineering is defined as an understanding and alteration of a legacy system to guarantee newly imposed performance requirements. The performance requirements may include a real-time throughput and an input-to-output latency. The proposed approach is based...

Resource provisioning considering scientific or realistic workload in a heterogeneous internet of things (IoT) environment presents significant challenges terms execution time and energy consumption. These arise due to the dynamic nature realistic-time workloads diverse characteristics IoT devices. In this study, we propose resource model that takes into account real-time environment. <br /&...

Many real projects complete through the realization of one and only one path of various possible network paths. Here, these networks are called alternative stochastic networks (ASNs). It is supposed that the nodes of considered network are probabilistic with exclusive-or receiver and exclusive-or emitter. First, an analytical approach is proposed to simplify the structure of t...
