Achievable data rates and power allocation for frequency-selective fading relay channels with imperfect channel estimation
(Springer Science+Business Media, 2012-12)
In this article, we investigate the information-theoretical performance of a cooperative orthogonal frequency division multiplexing (OFDM) system with imperfect channel estimation. Assuming the deployment of training-aided ...
Enhanced energetic reasoning-based lower bounds for the resource constrained project scheduling problem
(Elsevier, 2012-05)
We present new and effective lower bounds for the resource constrained project scheduling problem. This problem is widely known to be notoriously difficult to solve due to the lack of lower bounds that are both tight and ...
FPGA based particle identification in high energy physics experiments
(IEEE, 2012)
High energy physics experiments require on-the-fly processing of signals from many particle detectors. Such signals contain a high and fluctuating rate of pulses. Pulse shape hints particle type, and the amplitude relates ...
Cooperative communication techniques for future-generation HF radios
(IEEE, 2012-10)
When Hurricane Katrina hit the Gulf Coast of the United States in 2005, it severely damaged the telecommunications infrastructure, isolating the area from the outside world. With all the high-end emergency communication ...
Metaheuristics for the traveling salesman problem with pickups, deliveries and handling costs
(Elsevier, 2012-05)
This paper studies the Traveling Salesman Problem with Pickups, Deliveries, and Handling Costs. The subproblem of minimizing the handling cost for a fixed route is analyzed in detail. It is solved by means of an exact ...
Search for a light charged Higgs boson in top quark decays in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-07)
Results are presented on a search for a light charged Higgs boson that can be produced in the decay of the top quark t -> H(+)b and which, in turn, decays into tau(+)nu(tau). The analysed data correspond to an integrated ...
Yüksek-ölçekli mobil iletişim verilerinin açık-kaynak hadoop çerçevesi kullanılarak paralel ve iş-hatlı işlenmesi
(IEEE, 2012)
The fast increase in mobile device and bandwidth usage is generating big workloads on the IT infrastructures of mobile service providers and increasing management costs. These providers collect log files continuously and ...
Seyrek matris-vektör çarpımı için koşut zamanda özelleşmi̇ş kod üreti̇mi̇ ve deneysel opti̇mi̇zasyon
(IEEE, 2012)
Bu çalışmada seyrek matris-vektor çarpımı için matris içeriğine göre özelleşmiş, yüksek hızlı program üretimi yapan bir kütüphane tasarımı anlatılmaktadır. Kütüphane sinyal işleme uygulamaları, bilimsel hesaplamalar, sonlu ...
Verification and analysis of domain-specific models of physical characteristics in embedded control software
(Elsevier, 2012-12)
ContextA considerable portion of the software systems today are adopted in the embedded control domain. Embedded control software deals with controlling a physical system, and as such models of physical characteristics ...
Observation of Z decays to four leptons with the CMS detector at the LHC
(Springer Science+Business Media, 2012-12)
The first observation of the Z boson decaying to four leptons in proton-proton collisions is presented. The analyzed data set corresponds to an integrated luminosity of 5.02 fb(-1) at root s = 7 TeV collected by the CMS ...
