On improving recovery performance in erasure code based geo-diverse storage clusters Abstract-Erasure code based distributed storage systems are increasingly being used by storage providers for big data storage since they offer the same reliability as replication with significant decrease in the amount of storage required. But, when it comes to a storage system with data…
On Increasing the Slow-Fading Channel Diversity Using Block-Coded MIMO-OFDM With Reconfigurable Antennas Abstract? A new block coding scheme to increase the diversity gain of multiple-input?multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems over slow-fading wireless channels.We assume that the antenna elements at the transmitter are reconfigurable and capable of independently changing the physical characteristics of their…
On Learning of Choice Models with Interactive Attributes Abstract? approach to infer the unique and complex decision making process of a decision-maker (DM), which is characterized by the DM?s priorities and attitudinal character, along with the attributes interaction, to name a few. On the basis of exemplary preference information in the form of pairwise comparisons…
On Learning of Choice Models with Interactive Attributes Abstract? Introducing recent advances in the machine learning techniques to state-of-the-art discrete choice models, we develop an approach to infer the unique and complex decision making process of a decision-maker (DM), which is characterized by the DM?s priorities and attitudinal character, along with the attributes interaction, to…
On Maximizing Diffusion Speed Over Social Networks With Strategic Users Abstract? A variety of models have been proposed and analyzed to understand how a new innovation (e.g., a technology, a product, or even a behavior) diffuses over a social network, broadly classified into either of epidemic-based or game-based ones. In this paper, we consider a…
On Summarization and Timeline Generation for Evolutionary Tweet Streams Abstract? Abstract?Short-text messages such as tweets are being created and shared at an unprecedented rate. Tweets, in their raw form, while being informative, can also be overwhelming. For both end-users and data analysts, it is a nightmare to plow through millions of tweets which contain enormous…
On the Achievable Rate of OFDM With IndexModulation Abstract? Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a recently developed transmis-sion technique that extends the principle of spatial modulation to OFDM sub carriers.In this paper,the performance of OFDM-IM is studied in terms of the achievable rate assuming an -ary constellation and that channel state…
On the Energy Efficiency and Effective Throughput Tradeoff of Fading Channels Abstract? The tradeoff between the energy efficiency (EE) and the effective throughput (ET) of fading channels. In particular, we consider the case of zero channel state information (CSI) at the transmitter, and thus, the receiver can only successfully decode the source messages with certain…
On the Performance of Non-Orthogonal Multiple Access in 5G Systems with Randomly Deployed Users Abstract-In this letter, the performance of non-orthogonal multiple access (NOMA) is investigated in a cellular downlink scenario with randomly deployed users. The developed analytical results show that NOMA can achieve superior performance in terms of ergodic sumrates; however, the outage performance…
On the Permanence of EEG Signals for Biometric Recognition Abstract? Brain signals have been investigated for more than a century in the medical field. However, despite the broad interest in clinical applications, their use as a biometric identifier has been only recently considered by the scientific community. We focus on the permanence across time of…
On the use of Split-Ring Resonators and Complementary Split-Ring Resonators for Novel Printed Microwave Elements: Simulations, Experiments and Discussions Abstract?Making use of either split-ring resonators (SRRs) or complementary split-ring resonators (CSRRs). As an example in this paper, simple 50-? microstrip lines are loaded with SRR and CSRR, and very compact band-reject filters have been obtained….
Online Agricultural based Home Shopping & Guidance system Abstract-The main idea is to help the farmers regarding ?Agriculture? in order to give awareness by conducting camps Admin will create accounts for professors, village representatives, students. The articles are written by the professors in the Agriculture college/University. Students can enroll as volunteers who help to conduct…
