Traffic congestion has become a serious problem that arises in our cities; this is due to rapid population growth, the rapid increase in the number of cars. Therefore, there is an infernal traffic jams. It is in this light, it is imperative to eliminate or at least reduce traffic congestion through the adoption of the policy of ITS (intelligent transport systems). The objective of this paper is to propose a study on the problem of congestion in cities, by reducing traffic congestion.

Point matching is a problem of finding the optimum matching between two sets of key points which are extracted from the surfaces of objects. A popular approach represents the features of a set of points with a graph model. Traditionally, the measurement applied in the graph model is the Euclidian distance, which is not suitable for objects with non-rigid deformations. In this paper, we propose a novel graph model called the geodesic graph model (GGM) which uses a geodesic-like distance as its measurement. GGM can better tackle non-rigid deformations because the geodesic-like distance is a kind of invariant structural feature during non-rigid deformations. The building process of the GGM is justified under the assumption that all the key points are spanning on a manifold. To further handle the deviations of key point locations, we come up with a feature weighting process to increase our algorithm's robustness. We conduct several experiments on different kinds of deformations over several widely used datasets. Experimental results demonstrate the effectiveness of our algorithm.

Delay defects under high temperature have been one of the most critical factors to affect the reliability of computer systems, and the current test methods don't address this problem properly. In this paper, a temperature-aware software-based self-testing (SBST) technique is proposed to self-heat the processors within a high temperature range and effectively test delay faults under high temperature. First, it automatically generates high-quality test programs through automatic test instruction generation (ATIG), and avoids over-testing caused by nonfunctional patterns. Second, it exploits two effective powerintensive program transformations to self-heat up the processors internally. Third, it applies a greedy algorithm to search the optimized schedule of the test templates in order to generate the test program while making sure that the temperature of the processor under test is within the specified range. Experimental results show that the generated program is successful to guarantee delay test within the given temperature range, and achieves high test performance with functional patterns.

Resource utilization is one of the emerging problems in many-chip SSDs. In this paper, we propose Sprinkler, a novel device-level SSD controller, which targets maximizing resource utilization and achieving high performance without additional NAND flash chips. Specifically, Sprinkler relaxes parallelism dependency by scheduling I/O requests based on internal resource layout rather than the order imposed by the device-level queue. In addition, Sprinkler improves flash-level parallelism and reduces the number of transactions (i.e., improves transactionallocality) by over-committing flash memory requests to specific resources. Our extensive experimental evaluation using a cycle-accurate large-scale SSD simulation framework shows that a many-chip SSD equipped with our Sprinkler provides at least 56.6% shorter latency and 1.8 -2.2 times better throughput than the state-of-the-art SSD controllers. Further, it improves overall resource utilization by 68.8% under different I/O request patterns and provides, on average, 80.2% more flash-level parallelism by reducing half of the flash memory requests at runtime. © 2014 IEEE.

Solid State Disk (SSD) arrays are in a position to (as least partially) replace spinning disk arrays in high performance computing (HPC) systems due to their better performance and lower power consumption. However, these emerging SSD arrays are facing enormous challenges, which are not observed in disk-based arrays. Specifically, we observe that the performance of SSD arrays can significantly degrade due to various array-level resource contentions. In addition, their maintenance costs exponentially increase over time, which renders them diff cult to deploy widely in HPC systems. To address these challenges, we propose Triple-A, a non-SSD based Autonomic All-Flash Array, which is a self-optimizing, from-scratch NAND f ash cluster. Triple-A can detect two different types of resource contentions and autonomically alleviate them by reshaping the physical data-layout on its f ash array network. Our experimental evaluation using both real workloads and a micro-benchmark show that Triple-A can offer a 53% higher sustained throughput and a 80% lower I/O latency than non-autonomic SSD arrays Copyright © 2014 ACM.

In this paper, the off-body performance of a single-input single-output (SISO) system was evaluated in Non-Line-of-Sight (NLOS) situations and compared with measurements done with a clear Line of Sight (LOS) link. The obstructed link study takes into account the human shadowing effect, usually caused by close by miners interrupting the transmitter-receiver link. Measurement campaigns were performed using Monopole antennas in an underground gold mine. The off-body channels were characterized in terms of the channel impulse response, RMS delay spread, and coherence bandwidth. The channel capacity was determined using the well-known Shannon formula for LOS and NLOS situations. The variation of the channel parameters in the different measurement scenarios was analyzed.

eHealth governance and regulation are necessary in low resource African countries to ensure effective and equitable use of health information technology and to realize national eHealth goals such as interoperability, adoption of standards and data integration. eHealth regulatory frameworks are under- developed in low resource settings, which hampers the progression towards coherent and effective national health information systems. Ontologies have the potential to clarify issues around interoperability and the effectiveness of different standards to deal with different aspects of interoperability. Ontologies can facilitate drafting, reusing, implementing and compliance testing of eHealth regulations. In this regard, we have developed an OWL ontology to capture key concepts and relations concerning interoperability and standards. The ontology includes an operational definition for interoperability and is an initial step towards the development of a knowledge representation modeling platform for eHealth regulation and governance. © Springer-Verlag Berlin Heidelberg 2014.

Prior mobile malware defensive means is usually retroactive, which may either lead to high false negatives or can hardly recover systems states from malware activities. PreCrime is a proactive malware detection scheme that detects and stops malware activities from happening. PreCrime creates mirrors of a mobile device in a resource-rich and trusted cloud, which speculatively executes multiple likely user operations concurrently to detect potential tampering and information leakage. Our preliminary evaluation shows that PreCrime introduces small performance overhead on smartphones and feasible delay during speculative execution on the cloud. © 2014 ACM.
