Efficient Genre-Specific Semantic Video Indexing Abstract? Large video collections such as YouTube contain many different video genres, while in many applications the user might be interested in one or two specific video genres only. Thus, when users are querying the system with a specific semantic concept like AnchorPerson, and MovieStars, they are likely aiming…
A Two-Level FH-CDMA Scheme for Wireless Communication Systems over Fading Channels Abstract– Efficient margin adaptive scheduling for MIMO OFDMA systems. In this paper we address the problem of margin adaptive scheduling in the downlink of an orthogonal frequency division multiple access (OFDMA) multiple-input multiple-output (MIMO) system. Optimal resource allocation in MIMO systems requires the joint…
Efficient method for events detection in phonocardiographic signals Abstract?The auscultation of the heart is still the first basic analysis tool used to evaluate the functional state of the heart, as well as the first indicator used to submit the patient to a cardiologist. In order to improve the diagnosis capabilities of auscultation, signal processing…
Efficient Motif Discovery for Large-Scale Time Series in Healthcare Abstract? Analyzing time series data can reveal the temporal behavior of the underlying mechanism producing the data. Time series motifs, which are similar subsequences or frequently occurring patterns, have signi?cant meanings for researchers especially in medical domain. With the fast growth of time series data, traditional…
Efficient Multi-User Computation Offloading for Mobile-Edge Cloud Computing Abstract? Efficient Multi-User Computation Offloading for Mobile-Edge Cloud Computing. Mobile-edge cloud computing is a new paradigm to provide cloud computing capabilities at the edge of pervasive radio access networks in close proximity to mobile users. We first study the multi-user computation offloading problem for mobile-edge cloud computing…
Efficient Optimal Algorithm of Task Scheduling in Cloud Computing Environment Abstract? Cloud computing is an emerging technology in distributed computing which facilitates pay per model as per user demand and requirement. Cloud consist of a collection of virtual machine which includes both computational and storage facility. The primary aim of cloud computing is to provide…
Efficient Prediction of Difficult Keyword Queries Abstract?Efficient Prediction of Difficult Keyword Queries. Keyword queries on databases provide easy access to data, but often suffer from low ranking quality, i.e., low precision and/or recall, as shown in recent benchmarks. It would be useful to identify queries that are likely to have low ranking quality to improve…
Efficient Range – Based Storage Management for Scalable Datastores Abstract?Scalable datastores are distributed storage systems capable of managing enormous amounts of structured data for online serving and analytics applications. Across different workloads, they weaken the relational and transactional assumptions of traditional databases to achieve horizontal scalability and availability, and meet demanding throughput and latency requirements….
Efficient Register Renaming and Recovery for High-Performance Processors Abstract?Quantum-dot cellular automata (QCA) are an attractive emerging technology suitable for the development of ultra-dense low-power high-performance digital circuits. Efficient solutions have recently been proposed for several arithmetic circuits, such as adders, multipliers, and comparators. Nevertheless, since the design of digital circuits in QCA still poses several…
Efficient Register Renaming and Recovery forHigh-Performance Processors Abstract-Efficient Register Renaming and Recovery forHigh-Performance Processors. Modern superscalar processors implement register renaming using either random access memory (RAM) or content-addressable memories (CAM) tables. The design of these structures should address both access time and misprediction recovery penalty. Although direct-mapped RAMs provide faster access times, CAMs are more…
Efficient Resonant Frequency Modeling for Dual-Band Microstrip Antennas by GaussianProcessRegression Abstract? Efficient Resonant Frequency Modeling for Dual-Band Microstrip Antennas by Gaussian Process Regression. A methodology based on Gaussian process regression (GPR) for accurately modeling the resonant frequencies of dual-band microstrip antennas is presented. Two kinds of dual-band antennas were considered, namely a U-slot patch and…
Efficient Spread Spectrum Communication without Preshared Secrets Abstract– Efficient Spread Spectrum Communication without Preshared Secrets. Spread spectrum (SS) communication relies on the assumption that some secret is shared beforehand among communicating nodes to establish the spreading sequence for long-term wireless communication. Strasser et al. identified this as the circular dependency problem (CDP). This problem is…
