Increasing test efficiency by risk-driven model-based testing
(Elsevier, 2018-10)
We introduce an approach and a tool, RIMA, for adapting test models used for model-based testing to augment information regarding failure risk. We represent test models in the form of Markov chains. These models comprise ...
Energy sensing strategy optimization for opportunistic spectrum access
(IEEE, 2012-06)
This paper introduces a correlator-based energy sensing strategy for opportunistic spectrum access in a slow, flat-fading channel. The correlator provides weighted energy accumulation in time. We assume that the noise ...
Fast two-pick n2n round-robin arbiter circuit
(IEEE, 2012-06)
A regular (one-pick) round-robin arbiter circuit picks one active requester (if any) out of n requesters. A two-pick round-robin arbiter selects up to two requesters. An n2n two-pick round-robin arbiter indicates the picked ...
Integrated blood collection and appointment scheduling
(Institute of Industrial Engineers, 2012)
Considering the processing requirements of donated blood, we study an integrated blood collection and appointment scheduling problem. We develop a mixed integer programming model to maximize the amount of donated blood ...
Practical implementation and performance study of a hard-switched hybrid FSO/RF link under controlled fog environment
(IEEE, 2014)
The availability and performance of terrestrial free-space optical (FSO) communication systems are heavily deterred by the fluctuating conditions of the atmospheric channel, particularly in the presence of visibility-limiting ...
Multi-hop relaying over the atmospheric poisson channel: outage analysis and optimization
(IEEE, 2012-03)
In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ...
Outage performance of MIMO free-space optical systems in gamma-gamma fading channels
(IEEE, 2013)
In this paper, we consider a MIMO Free-Space Optical (FSO) communication system over gamma-gamma turbulence channels and derive a closed-form analytical expression for the outage probability taking into account the effects ...
Energy optimized routing with directional antennas and tagging for multimedia sensor networks
(IEEE, 2018-04-24)
Several routing optimization strategies have been proposed in research for Wireless Multimedia Sensor Network (WMSN), because of unavailability of the external power source. In this paper, a global energy optimization ...
Outage performance analysis of mth best path selection protocol in FSO communications
(IEEE, 2014)
In this paper, we investigate the performance of free space optical (FSO) systems with parallel multihop relaying and path selection. Specifically, we consider an FSO communication system which employs M parallel relaying ...
A chance constraint based multi-item production planning model using simulation optimization
(IEEE, 2016)
We consider a single stage multi-item production-inventory system under stochastic demand. We had previously proposed a production planning model integrating ideas from forecast evolution and inventory theory to plan work ...
