Information theoretic analysis of hybrid-ARQ protocols in coherent free-space optical systems
(IEEE, 2012-05)
Automatic retransmission request (ARQ) is a feedback-based data link layer technique which enhances the reliability of communication in fading channels. In this paper, we investigate the performance of hybrid-ARQ (H-ARQ) ...
Realtime healthcare services via nested complex event processing technology
(The ACM Digital Library, 2012)
Complex Event Processing (CEP) over event streams has become increasingly important for real-time applications ranging from healthcare to supply chain management. In such applications, arbitrarily complex sequence patterns ...
Measurement of the top-quark mass in t(t)over-bar events with dilepton final states in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2012-10)
The top-quark mass is measured in proton-proton collisions at root s = 7 TeV using a data sample corresponding to an integrated luminosity of 5.0 fb(-1) collected by the CMS experiment at the LHC. The measurement is performed ...
Modelling and solving an m-location, n-courier, priority-based planning problem on a network
(Springer Nature, 2012-01)
In this paper, we study an m-location, n-courier, priority-based planning problem on a network, which we refer to as the Courier Planning Problem (CPP). The CPP arises on a daily basis in the context of planning the ...
Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
(IEEE, 2012)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the resence of sparse underwater acoustic ...
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 ...
