In this letter, we address the performance analysis of underlay selective decode-and-forward (DF) relay networks in Rayleigh fading channels with non-necessarily identical fading parameters. In particular, a novel result on the outage probability of the considered system is presented. Monte Carlo simulations are performed to verify the correctness of our exact closed-form expression. Our propos...
This paper investigates the simultaneous wireless information and power transfer (SWIPT) for twohop orthogonal frequency division multiplexing (OFDM) decode-and-forward (DF) relay communication system, where a relay harvests energy from radio frequency signals transmitted by the source and then uses the harvested energy to assist the information transmission from the source to its destination. ...

background: following the outbreak of eltor cholera in iraq’s kurdistan, iran was threatened through the western border. therefore, the aim of the present study was to evaluate the health system response of marivan city in kurdistan province (iran) as a risky gateway for the outbreak of eltor cholera epidemic in iran. materials and methods: this cross-sectional study was implemented in marivan ...
In terms of modern applications of wireless sensor networks in smart cities, relay terminals can be employed to simultaneously deliver both information and energy to a designated receiver by harvesting power via radio frequency (RF). In this paper, we propose time switching aware channel (TSAC) protocol and consider a dual-hop full-duplex (FD) relaying system, where the energy constrained relay...
Although the application of data fusion in information retrieval has yielded good results in the majority of the cases, it has been noticed that its achievement is dependent on the quality of the input result lists. In order to tackle this problem, in this paper we explore the combination of only the n-top result lists as an alternative to the fusion of all available data. In particular, we des...
The weight distribution {W C }w=0 of a linear code C ⊂ Fq is put in an explicit bijective correspondence with Duursma’s reduced polynomial DC(t) ∈ Q[t] of C. We prove that the Riemann Hypothesis Analogue for a linear code C requires the formal self-duality of C and imposes an upper bound on the cardinality q of the basic field, depending on the dimension and the minimum distance of C. Duursma’s...
Stone-Weierstrass-type theorems for groups of group-valued functions with discrete range or discrete domain are obtained. We study criteria for a subgroup of the group of continuous functions C(X,G) (X compact, G a topological group) to be uniformly dense. These criteria are based on the existence of so-called condensing functions, where a continuous function φ : G → G is said to be condensing ...

This paper follows on from a group of internationally published papers in the area of investigating anthropomorphic user interface feedback. In this paper an experiment is described which aims to examine the effectiveness and user approval issues of anthropomorphic versus non-anthropomorphic user interface feedback. This experiment is highly relevant to the research community as Computer Scient...
