Outage Analysis of Clustered Cooperative Networks in Generalized Fading and Shadowing

Telfor Journal, 2016
In this paper, the outage probability of a noise-limited decode-and-forward wireless cooperative network cluster, subject to the Nakagami-m multipath fading and Gamma shadowing is investigated.

Impact of Hardware Impairments on Outage Performance of Hybrid Satellite-Terrestrial Relay Systems

IEEE Access, 2019
The hardware impairments of transceiver nodes that generate signal distortions degrade the reliability performance of communication systems. This paper investigates the impact of hardware imperfections on the outage performance of hybrid satellite ...

Exact and metaheuristic approaches to minimizing makespan in parallel machine scheduling with conflicting jobs

International Transactions in Operational Research, EarlyView.
Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

Outage Performance of Two-Hop OFDM Systems With Spatially Random Decode-and-Forward Relays

IEEE Access, 2017
In this paper, we analyze the outage performance of different multicarrier relay selection schemes for two-hop orthogonal frequency-division multiplexing (OFDM) systems in a Poisson field of relays. In particular, special emphasis is placed on decode-and-

Outage Probability Analysis of FSO Links Over Foggy Channel

IEEE Photonics Journal, 2017
Outdoor free-space optic (FSO) communication systems are sensitive to atmospheric impairments, such as turbulence and fog, in addition to being subject to pointing errors.

Make or Buy Decisions and Data Sharing

The Journal of Industrial Economics, EarlyView.
ABSTRACT Firms can share data to discover potential synergies between their data sets and algorithms, eventually leading to more efficient mergers and acquisitions (M&A) decisions. However, data sharing also modifies the competitive balance when firms do not merge, and a company may be reluctant to share data with potential rivals.

Outage probability of a cognitive cooperative relay network with multiple primary users under primary outage constraint [PDF]

, 2016
In this paper, we consider a cognitive cooperative relay network (CCRN) that utilizes a decode-and-forward relay in the presence of multiple primary users.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

Mathematical Finance, EarlyView.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Outage probability of hybrid CDMA network with spatial Poisson traffic [PDF]

, 2011
In this paper we study the outage probability of a hybrid CDMA wireless network in path loss channel. In the considered hybrid network an infrastructure of base stations is considered in order to improve the ad hoc network connectivity. Base stations are

The effects of far‐UVC irradiation on the presence and concentration of ESKAPEE pathogens on hospital surfaces: Study protocol for a multi‐site, double‐blinded randomized controlled trial in La Paz, Bolivia

Photochemistry and Photobiology, EarlyView.
The protocol of a multi‐site, double‐blinded, clustered randomized controlled trial (cRCT) with a binary outcome of the presence of viable presumptive ESKAPEE pathogens on surfaces in and around hospital sinks is to be implemented in two Bolivian hospitals.
