Agile-SD is one of the latest versions of loss-based Congestion Control Algorithm (CCA), which has been proposed to improve the total performance of TCP over high-speed and short-distance networks. It has introduced a new mechanism, called Agility Factor Mechanism (AFM), which shortens the epoch time to reduce the sensitivity to packet losses and in turn to increase the average throughput. Agile-SD has only been tested via simulation, however, it has not been mathematically proven or evaluated. The contribution of this paper is twofold: First, a new mathematical model for the throughput of NewReno and Agile-SD is proposed. This model is designed using the well-known Markov chains to validate the correctness of Agile-SD and to show the impact of buffer size, multiplicative decrease factor and maximum limit of agility factor (λmax) on the total performance. Second, an Automated Algorithm Configuration and Parameter Tuning (AACPT) technique is employed to optimize and automate the configuration of λmax. Further, the numerical results for both NewReno and Agile-SD are compared to the simulation results in which the validity of the proposed model is confirmed. Moreover, the output of AACPT is exploited to formulate a new equation which calculates the optimal λmax from a given β in order to conserve the standard interface of TCP. This equation increases the scalability of Agile-SD and improves its total performance. Copyright © 2017, The Authors. All rights reserved.

Load testing is the process of applying ordinary stress to a software system to determine the system performance under normal conditions. In a typical load testing lifecycle, three kinds of service tools are involved: test case recording service tools that make testers easier to generate test cases through a web browsing-like behavior;test case execution service tools that exercise test cases with simulations of a large number of concurrent users;system resource monitoring service tools that provide information of system footprints during the test case executions. However, using these three kinds of service tools one by one to complete a load testing may require extra effort on operating and configuring each service. In this paper, we proposed a framework for composing the three types of service tools as an integrated service for load testing. A raw test case recorded by Badboy tool is automatically converted into an expanded test case that can be executed by JMeter. JMeter and Cacti are then automatically invoked by the framework. The execution time period of JMeter is automatically identified as the input to Cacti for resource monitoring of the system under test. The test report together with system footprints is also automatically generated. In the experimental evaluation, the result shows that the framework significantly save time on operating and configuring the load testing service tools than the traditional approach under a t-test. © 2016 Taylor & Francis Group.

We study the robustness of an evolving system that is driven by successive inclusions of new elements or constituents with m random interactions to older ones. Each constitutive element in the model stays either active or is temporarily inactivated depending upon the influence of the other active elements. If the time spent by an element in the inactivated state reaches TW, it gets extinct. The phase diagram of this dynamic model as a function of m and TW is investigated by numerical and analytical methods and as a result both growing (robust) as well as non-growing (volatile) phases are identified. It is also found that larger time limit TW enhances the system's robustness against the inclusion of new elements, mainly due to the system's increased ability to reject "falling-together" type attacks. Our results suggest that the ability of an element to survive in an unfavorable situation for a while, either as a minority or in a dormant state, could improve the robustness of the entire system.

The hot streak, loosely defined as winning begets more winnings, highlights a specific period during which an individual’s performance is substantially higher than her typical performance. While widely debated in sports1–3, gambling4–7, and financial markets8–10 over the past several decades, little is known if hot streaks apply to individual careers. Here, building on rich literature on lifecycle of creativity11–23, we collected large-scale career histories of individual artists, movie directors and scientists, tracing the artworks, movies, and scientific publications they produced. We find that, across all three domains, hit works within a career show a high degree of temporal regularity, each career being characterized by bursts of high-impact works occurring in sequence. We demonstrate that these observations can beexplained by a simple hot-streak model we developed, allowing us to probe quantitatively the hot streak phenomenon governing individual careers, which we find to be remarkably universal across diverse domains we analyzed: The hot streaks are ubiquitous yet unique across different careers. While the vast majority of individuals have at least one hot streak, hot streaks are most likely to occur only once. The hot streak emerges randomly within an individual’s sequence of works, is temporally localized, and is unassociated with any detectable change in productivity. We show that, since works produced during hot streaks garner significantly more impact, the uncovered ho t streaks fundamentally drives the collective impact of an individual, ignoring which leads us to systematically over- or under-estimate the future impact of a career. These results not only deepen our quantitative understanding of patterns governing individual ingenuity and success, they may also have implications for decisions and policies involving predicting and nurturing individuals with lasting impact.

IEEE 802.11e standard introduces HCF Controlled Channel Access (HCCA) to support quality of service (QoS) for multimedia traffics. In HCCA, the traffics scheduled according to their mean characteristics which favors the Constant Bit Rate (CBR) trans- mission approach. However, it does not efficiently cope with the fluctuation of the Variable Bit Rate (VBR) video streams where the traffic shows deviation from its mean during the traffic lifetime. In this paper, we propose a packet based polling mechanism to enhance the scheduling of pre-recorded VBR video streams in HCCA function. Our approach exploits feedback information about the arrival time of the subsequent video frame obtained through cross-layering approach to accurately schedule the uplink traffics. Simulation experiments reveal the efficiency of the proposed mechanism in providing less delay and high throughput while maintaining medium channel.

A concept of Cloud Radio Access networks (C-RANs) with Power over Fiber (PoF) is expected to work as a post-disaster access network architecture. In this architecture, since external power is supplied to Remote Radio Heads (RRHs) through the optical-fiber cable for data communication, RRHs can operate even when power cables are disrupted due to disasters. This network, however, needs to reduce the power consumption for RRH operation and consider Quality of Experience (QoE) to provide sustainable service with enough user satisfaction. To this end, we propose user position guidance approaches which give advices of the best position to users. Our proposed approaches are able to achieve high sustainability while satisfying the QoE constraint. Furthermore, the effectiveness of our proposed approaches is evaluated by numerical calculation.

Graphene Quantum Dots (GQD) is used for detecting lard substance. It is discovered that the fluorescence for a GQD with a size approximately 5nm in size will have a peak at 675nm. Introducing lard substance to the GQD will induce a broad fluorescence spectrum at the range of 415 till 715nm. Higher fluorescence is observed from 760nm till 860nm showing the dynamics fluorescence changes when lard is applied. These fluorescence dynamics when lard is introduced is due to the functional groups of Carbon-Carbon interaction between GQD and lard. © 2016 IEEE.

Centrality is widely recognized as one of the most critical measures to provide insight in the structure and function of complex networks. While various centrality measures have been proposed for single-layer networks, a general framework for studying centrality in multilayer networks (i.e., multicentrality) is still lacking. In this study, a tensor-based framework is introduced to study eigenvector multicentrality, which enables the quantification of the impact of interlayer influence on multicentrality, providing a systematic way to describe how multicentrality propagates across different layers. This framework can leverage prior knowledge about the interplay among layers to better characterize multicentrality for varying scenarios. Two interesting cases are presented to illustrate how to model multilayer influence by choosing appropriate functions of interlayer influence and design algorithms to calculate eigenvector multicentrality. This framework is applied to analyze several empirical multilayer networks, and the results corroborate that it can quantify the influence among layers and multicentrality of nodes effectively.
