In this paper, we investigate an efficient scheme for data multicasting in narrowband public safety radio systems. The proposed scheme uses fountain encoding, in order to avoid feedback messages for each individual packet. We first propose a multistage estimation scheme that is based on slotted random access and that does not require any prior knowledge of number of users. The rest of the proposed scheme consists of iterative transmission and feedback/estimation phases. In feedback phases, the base station estimates the number of users that did not decode the data file yet, and determines the number of additional fountain encoded packets required. This phase does not require any channel state information. The proposed scheme lasts until all the users in the group decode the message. We show that the proposed estimation scheme is accurate and computationally efficient. The overall multicast scheme performs very close to an optimistic lower bound, which makes it a promising multicast approach in public safety radio systems such as APCO P25.

Effective induction of gene regulatory networks using a novel recommendation method Ozsoy, Makbule Gulcin; Polat, Faruk; Alhajj, Reda (2019-01-01) In this paper, we introduce a method based on recommendation systems to predict the structure of Gene Regulatory Networks (GRNs) making use of data from multiple sources. Our method is based on collaborative filtering approach enhanced with multiple criteria to predict the relationships of genes, i.e., which genes regulate others. We conduct experiments on two data sets to demonstrate the applicability and sustainability of our proposal. The first data set is composed of microarray data and Transcription Fa...
Hybrid Approach for Mobile Couriers Election in Smart-cities Al-Turjman, Fadi (2016-11-10) In this paper we propose a hybrid heuristic approach for public data delivery under ultra-large-scale smart-city settings. In this approach, public transportation vehicles are going into election process to be utilized as Mobile Couriers (MCs) that read public Access Points (APs) data loads and relay it back to a central processing base-station. We also introduce a cost-based fitness function for the MCs election in the smart-city project which forms a real implementation for the Internet of Things (IoT) pa...
A new algorithm and computation approach for economic dispatch with prohibited operating zones in power systems Cetinkaya, N; Urkmez, A; Erkmen, İsmet; Yalcinoz, T (2005-01-01) This paper presents a new algorithm and computation approach to solve the economic load dispatch (ELD) in electrical power systems. We applied a new power formula to solve the LLD problem. If production units cost Curves are represented property then ELD becomes More Correct. In this respect we assumed that production units have prohibited operating zones. Cost curves of the production units are generally accepted as piece-wise quadratic function. The power production is cheaper since we do not use the prod...
Effective PET and ICT switching of boradiazaindacene emission: A unimolecular, emission-mode, molecular half-subtractor with reconfigurable logic gates Coskun, A; Deniz, E; Akkaya, EU (American Chemical Society (ACS), 2005-11-10) We report a unimolecular system functioning as a combinatorial logic circuit for half-subtractor. The emission characteristics can be modulated by chemical inputs, and when followed at two different wavelengths, two functionally integrated logic gates XOR and INHIBIT are obtained. Both logic gates function in the emission mode, and with very large differences in the signal intensity allowing unequivocal assignment of logic-0 and logic-1.
Reliable Transmission of Short Packets Through Queues and Noisy Channels Under Latency and Peak-Age Violation Guarantees Devassy, Rahul; Durisi, Giuseppe; Ferrante, Guido Carlo; Simeone, Osvaldo; Uysal, Elif (Institute of Electrical and Electronics Engineers (IEEE), 2019-04-01) This paper investigates the probability that the delay and the peak-age of information exceed a desired threshold in a point-to-point communication system with short information packets. The packets are generated according to a stationary memoryless Bernoulli process, placed in a single-server queue and then transmitted over a wireless channel. A variable-length stop-feedback coding scheme-a general strategy that encompasses simple automatic repetition request (ARQ) and more sophisticated hybrid ARQ techniq...
