Surprising Observation

This paper focuses on the improvement in the quality of computation provided by parallelism. The problem of interest is that of computing the maximum of a nonlinear feedback function in a real-time environment. We show that the solution obtained in parallel is significantly, provably, and consistently better than a sequential one. It is important to note that our purpose is not to demonstrate merely that a parallel computer can obtain a solution to a computational problem that is of higher quality than one derived sequentially. The latter is an interesting (and often surprising) observation in its own right, but we wish to go further. It is shown here that the improvement in quality due to parallelism can be arbitrarily high. To be specific, the ratio of the parallel solution to the sequential one is typically superlinear in the number of processors used by the parallel computer. This result is akin to superlinear speedup—a phenomenon itself originally thought to be impossible.

The nanometric scale researches results can be found, in present, in every industry domains, due to the effects of the new products, obtained on the basis of this researches. In the concrete industry, the research goal at this level is to obtain, finally, a material with new features, whose structural behavior to be considerably better than of the current one. Basically, it aims to achieve, using nanotechnologies, a new structural material for constructions, starting from the current concrete advantages (good compressive strength, durability, etc.), eliminating the disadvantages (low tensile resistance, cracks, etc.), and controlling, in the same time, the costs. Thus, in this paper are presented the required parameters in order to obtain this kind of material, by highlighting the nanocomponents characteristics and the quantities that are used to achieve the expected quality requirements. The real time influence of these nanocomponents on the quality of the studied material can be observed using a dedicated software, specially developed for this purpose.

The P2P technology consumes the largest proportion of network traffic and is usually encrypted, which is lack of supervision. Accurate and rapid identification of encrypted P2P traffic, represented by the famous Skype, is of great significance to improve the network quality of service and enhance security control. In this paper, a trends-aware protocol fingerprints model is proposed based on the statistical signatures of signaling interactions and content transfer phase of Skype. The proposed method can sense traffic trends by trends-aware weighting functions and identify Skype traffic with anomaly scores in real-time. Experimental results show that the precision and real-time performances of the proposed algorithm is better than several state-of-art encrypted traffic identification methods, such as the protocol fingerprints and C4.5 algorithm.

Aims: To assess the quality of real time elastography as a differential diagnosis tool for breast nodules and to compare it with standard ultrasonography. Material and methods: In this prospective study we enrolled 174 patients in which 174 dominant breast nodules were considered for the final diagnosis. The results of ultrasonography and real time elastography, both qualitative and quantitative, were compared with pathology findings from the biopsy specimens. Results: Pathology examinations determined 102 nodules were benign and 72 malignant. Qualitative elastography had a better diagnostic performance (82.4% sensitivity and 81.9% specificity) than ultrasonography plus Doppler evaluation (70.3% sensitivity and 73.5% specificity). Quantitative elastography, assessed using the fat-to-lesion ratio, was a good discriminant for malignancy (AUROC = 0.93, p < 0.001). Our results pointed to an optimal threshold for malignancy of > 4.88; by using this threshold, the diagnostic reliability of the fat-to-lesion ratio was better than both ultrasonography and qualitative elastography (86.5% sensitivity and 90.4% specificity). Conclusion: Real time elastography is superior to ultrasonography in diagnosing malignant breast nodules. The evaluation of nodules using a fat-to-lesion ratio was a better discriminant for malignancy than qualitative elastography.

The purpose of this study is (1) to analyze public perception on urban services before and after the expansion of the region, (2) analyze the level of people's satisfaction with urban services, and (3) analyze the determinants of the variables that determine what level of people's satisfaction urban services. This study concluded that first, after the expansion, the quality of urban services in South Tangerang City is better than before. Secondly, however, public satisfaction with the services only reached 48.53% (poor scale). Third, by using a Cartesian Diagram, the second priority that must be addressed are: (1) clarity of service personnel, (2) the discipline of service personnel, (3) responsibility for care workers; (4) the speed of service, (5) the ability of officers services, (6) obtain justice services, and (7) the courtesy and hospitality workers.

The compaction quality of the subgrade is directly related to the service life of the road. Effective control of the subgrade construction process is the key to ensuring the compaction quality of the subgrade. Therefore, real-time, comprehensive, rapid and accurate prediction of construction compaction quality through informatization detection method is an important guarantee for speeding up construction progress and ensuring subgrade compaction quality. Based on the function of the system, this paper puts forward the principle of system development and the development mode used in system development, and displays the development system in real-time to achieve the whole process control of subgrade construction quality.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.
