Evaluation of the Detection Capabilities of the ONOS SDN Controller

The process of monitoring the network, especially for larger ones, is very complex and contains many pitfalls. For instance the balance between granularity of information and their performance impact on the network. With the help of SDN this challenge can become easier, as it offers new methods, mechanisms and opportunities. One of the current most important Open Source controllers is the ONOS SDN controller. According to its developers it is a production ready controller that offers high availability due to its logically centralized and physically distributed architecture. But, as our investigations show, it is unable to cope with hazardous network conditions such as sporadic or recurring packet loss. It either does not detect packet loss or only detects it after long time periods, failing all common network availability targets.

Out-of-Pocket Medical Expenditures in the United States: Evidence from the Health and Retirement Study.

We use data from the Health and Retirement Study (HRS) to document the distribution of out-of-pocket medical spending among individuals aged 55 and over in the US. The HRS data permit us to examine out-of-pocket spending close to the end of life and to analyse the components of spending in more detail than has been done in previous studies. We find that spending risk rises sharply at older ages and near the end of life. While the median individual spent $6,328 out-of-pocket in the last year of life, 5 per cent were reported to have spent over $62,040. Our results also indicate that out-of-pocket spending is highly concentrated, with the top 10 per cent of spenders accounting for 42 per cent of all spending, and persistent, even over periods spanning many years. Finally, while certain categories of spending are very responsive to income and wealth, we do not find overall spending to be highly concentrated along these dimensions. Viewed within the international context, our results suggest that the fraction of households facing very high out-of-pocket spending is substantially greater in the US than in other developed countries.
Development of an Impedance Spectroscopy Measurement Circuit Board for Protein Detection

This study reports the results on the development of an electrical impedance-based protein detection circuit board for the protein detection biochip. A digital quadrature phase shift module, which can generate two sine waves with 90-degree difference in phase in a large frequency range is employed for lock-in amplifier block for impedance profiling. A microcontroller is used for frequency selection and data acquisition. The measurement module is connected with a computer to display the impedance profile. The implemented board were applied to protein detection biochip to detect the presence of the protein of interest in an essay sample. Experiment is performed for 10 μM Bovine serum albumin (BSA) labeled with fluorescein isothiocyanate (FITC-BSA) protein sample in 10 mM PBS medium solution with the frequency range from 10 kHz to 200 kHz. The measured results reveal a clear impedance change between before and after trapping protein on the microelectrodes of the biochip. The developed electrical impedance spectroscopy board enables rapid and effective protein detection at low concentration.

Elegant Placing Scheme Using Arduino Uno

The provocation that we are facing in everyday life is placing of the car in social places. When we stay distinct social areas such as the workplace, market, multiplex film lobby etc it is very difficult to find the possibility of placing space. This position signals for the demand for an elegant car placing a scheme which is furnished with sensors (Infrared) and microcontroller (Arduino UNO) to regularly calculate the cars placed in the space. In this paperwork, we are moving to build and make a model of elegant car placing a scheme which will be established on a computer network of properties. This introduces a scheme that advises customers to regularly search the empty accessible area in the placing location over the infrared sensors that are placed in every placing area and the customer can search the empty placing spaces using android apps of mobile gadget through the server. In other words, we can tell that it's an advanced method of conversation among the people and the properties. These all properties are concluded with the advice of current automation established on the computer network of properties.
Experimental Setup for the Evaluation of the Duty Cycle Influence over the Distorting Regime

This paper deals with specific aspects related to the PWM supplying of a load that consists of a uncontrolled rectifier, filtering elements (a coil and capacitor), a chopper with MOSFET and a DC motor. An original experimental setup was conceived. It allows the study of the influence exercised by a simple PWM technique's operational parameter (namely the duty cycle) along with the LC filter over the harmonic distortions of the waveforms acquired from the load terminals. Various operational contexts were addressed. The MATLAB/Simulink package was employed in order to design, simulate and implement the algorithm used in the control side. An interface relying on ControlDesk was conceived. Afterward, the algorithm was implemented in a real time setup by using the dSPACE controller board. An analysis of certain power quality indices (power factor, THD and distorting power factor) was made and conclusions were drawn.
Overload-Capability Analysis of PMSM Servo- and Robot-Drives Using DTC-SVM Methods: Part 1

Direct torque control with space vector modulation (DTC-SVM) is one of the best methods for controlling the electromagnetic torque of permanent magnet synchronous motor (PMSM) drives. This method grants excellent dynamic closed-loop torque-control performance. In this article (in Part 1) a new DTC-SVM method is presented which has excellent overload-capabilities, significantly exceeding even those of the original (classical) DTC-SVM method. The overload-capabilities of the new method are analyzed for both motor-mode and braking-mode.
A Closer Look at Real-World Patches

Bug fixing is a time-consuming and tedious task. To reduce the manual efforts in bug fixing, researchers have presented automated approaches to software repair. Unfortunately, recent studies have shown that the state-of-the-art techniques in automated repair tend to generate patches only for a small number of bugs even with quality issues (e.g., incorrect behavior and nonsensical changes). To improve automated program repair (APR) techniques, the community should deepen its knowledge on repair actions from real-world patches since most of the techniques rely on patches written by human developers. Previous investigations on real-world patches are limited to statement level that is not sufficiently fine-grained to build this knowledge. In this work, we contribute to building this knowledge via a systematic and fine-grained study of 16,450 bug fix commits from seven Java open-source projects. We find that there are opportunities for APR techniques to improve their effectiveness by looking at code elements that have not yet been investigated. We also discuss nine insights into tuning automated repair tools. For example, a small number of statement and expression types are recurrently impacted by real-world patches, and expression-level granularity could reduce search space of finding fix ingredients, where previous studies never explored.
Dispersion Based Highest-Modulation-First Last-Fit Spectrum Allocation Scheme for Elastic Optical Networks

This paper proposes a spectrum allocation scheme based on highest modulation-first last fit (LF) for elastic optical networks in order to suppress the call blocking in the network. The proposed scheme searches the available spectrum slots from the highest indexed spectrum slots and selects the slot position with the modulation level as high as possible, which guarantees the least spectrum slots consumption. It provides higher preference of the less robust modulation technique in order to minimize the number of required slots. The last fit spectrum allocation policy is used to keep lower indexed position slots available as much as possible, which have less dispersion effect, for incoming lightpath requests and gives them the opportunity to use the less number of slots. We introduce a dispersion-based highest modulation-first LF algorithm for allocation lightpath requests. The numerical results indicate that the proposed scheme outperforms the conventional schemes in terms of blocking probability, modulation usage ratio, and average number of required spectrum slots.
An Efficient Implementation of WiFi-Based High Availability Intelligent Power Cloud Platform

WiFi is one of the brightest areas of the communications business. With the popularization of mobile terminals and intelligent robots in provincial electric power companies' substations and power supply business halls, the problem how to manage various terminals has caused great concern in the academic and industrial circles. Therefore, it is necessary to set up a unified WiFi-based power cloud platform which satisfies provincial electric power companies' security standard. In this paper, we propose a WiFi-based high availability intelligent power cloud platform. It can effectively satisfy the unified management requirements for multi-faceted, geographically distributed WiFi network devices. The WiFi-based high availability intelligent power cloud platform has been successfully applied in a provincial electric power company.
Reframing Convergent and Divergent Thought for the 21st Century

Convergent thought is defined and measured in terms of the ability to perform on tasks where there is a single correct solution, and divergent thought is defined and measured in terms of the ability to generate multiple different solutions. However, this characterization of them presents inconsistencies, and despite that they are promoted as key constructs of creativity, they do not capture the capacity to reiteratively modify an idea in light of new perspectives arising out of an overarching conceptual framework. Research on formal models of concepts and their interactions suggests that different creative outputs may be projections of the same underlying idea at different phases of this kind of 'honing' process. This leads us to redefine convergent thought as thought in which the relevant concepts are considered from conventional contexts, and divergent thought as thought in which they are considered from unconventional contexts. Implications for the assessment of creativity are discussed.
On Current THD Extreme Switching Sequences for a Single-Phase Cascade H-Bridge Inverter with Phase-Shifted PWM and Non-Equal DC Sources

Cascade H-bridge inverter with Phase-Shifted Pulse Width Modulation (PS-PWM) is an attractive choice for integration of DC sources of different nature. Non-equal DC sources compromise current Total Harmonic Distortion (THD) by introducing undesirable low frequency subharmonics. This paper suggests that, for more than 3 H-bridges, there are two unique current Total Harmonic Distortion (THD) extreme DC source switching sequences on a PWM period-the best that minimizes undesirable low frequency current harmonic content (minimal THD) and the worst that delivers maximal current THD. These extreme sequences depend solely on DC source voltage inequality relationships.
Investigation on Dielectric Properties of Glucose Aqueous Solutions at 500 KHz-5MHz for Noninvasive Blood Glucose Monitoring

Noninvasive blood glucose monitoring (NBGM) provides patient with diabetes a prospective approach with the characteristics of painless and sustainable monitoring. In this study, the dielectric properties of glucose aqueous solutions, namely, deionized water solutions and saline solutions were studied. Specifically, the conductivity and the dielectric constant were measured by using impedance analyzer in the frequencies range of 500 KHz to 5MHz at 25°C. The results showed that both the dielectric constant and the conductivity for the two types of glucose aqueous solutions decreased with the increase of glucose concentration in the above frequency band. By comparing the two solutions with human blood, it was found that the dielectric properties of physiological saline are closer to that of human blood. In the study, saline solution was adopted as research object. In order to formulate the relationship between the dielectric properties of saline solutions and glucose concentration, the third-order Cole-Cole model for each glucose concentration was developed and the coefficient of determination R2 was as higher as 0.99. In addition, a second-order polynomial is used to model the glucose concentration dependence for the Cole–Cole parameters. The result indicates that the NBGM at low frequencies has potentials in practical applications.
Human Herpesvirus 6 and Malignancy: A Review

In order to determine the role of human herpesvirus 6 (HHV-6) in human disease, several confounding factors, including methods of detection, types of controls, and the ubiquitous nature of the virus, must be considered. This is particularly problematic in the case of cancer, in which rates of detection vary greatly among studies. To determine what part, if any, HHV-6 plays in oncogenesis, a review of the literature was performed. There is evidence that HHV-6 is present in certain types of cancer; however, detection of the virus within tumor cells is insufficient for assigning a direct role of HHV-6 in tumorigenesis. Findings supportive of a causal role for a virus in cancer include presence of the virus in a large proportion of cases, presence of the virus in most tumor cells, and virus-induced in-vitro cell transformation. HHV-6, if not directly oncogenic, may act as a contributory factor that indirectly enhances tumor cell growth, in some cases by cooperation with other viruses. Another possibility is that HHV-6 may merely be an opportunistic virus that thrives in the immunodeficient tumor microenvironment. Although many studies have been carried out, it is still premature to definitively implicate HHV-6 in several human cancers. In some instances, evidence suggests that HHV-6 may cooperate with other viruses, including EBV, HPV, and HHV-8, in the development of cancer, and HHV-6 may have a role in such conditions as nodular sclerosis Hodgkin lymphoma, gastrointestinal cancer, glial tumors, and oral cancers. However, further studies will be required to determine the exact contributions of HHV-6 to tumorigenesis.
Downlink Outage Analysis for Cognitive Cooperative Radio Networks Employing Non-Orthogonal Multiple Access

In this paper, we employ power-domain non-orthogonal multiple access (NOMA) to simultaneously transmit signals to both a primary user (PU) and a secondary user (SU) of a cognitive cooperative radio network (CCRN). Higher priority is given to the PU over the SU by keeping the power allocation coefficients at the base station (BS) and relay (R) above a certain threshold. In this way, similar as the interference power limit imposed by the PU in a conventional underlay CCRN, the power allocation coefficients at the BS and R of the CCRN can be controlled to maintain a given outage performance. Analytical expressions of the cumulative distribution function of the end-to-end signal-to-interference-plus-noise ratios at the PU and SU are derived and then used to assess the outage probabilities of both users. Numerical results are presented to study the impact of system parameters on outage performance of the CCRN with power-domain NOMA. In addition, it is illustrated that increased downlink performance can be obtained by combining power-domain NOMA with CCRNs.
A Distributed Mode Selection Approach Based on Evolutionary Game for Device-to-Device Communications

As one of the key technologies for the fifth generation (5G) mobile networks, device-to-device (D2D) communications offer promising benefits such as high spectrum efficiency, traffic offloading, and enhanced coverage. Depending on the resource sharing between D2D users and regular cellular users, a D2D user equipment (UE) can dynamically switch its communication mode to improve the quality of service (QoS) and user experience. Mode selection is an essential issue to ensure the QoS of D2D UEs while maximizing the system capacity. In this paper, we investigate the D2D mode selection problem from a novel perspective. In addition to the classic cellular mode and direct reuse mode, we further consider a relay mode for D2D UEs. Moreover, in order to address a potentially large population of D2D UEs, we propose an evolutionary game-based approach for D2D mode selection. The evolutionary game is formulated with a utility function that takes into account both the achievable throughput of D2D UEs and the radio resource consumption. Based on the evolutionary game formulation, we implement selection dynamics, i.e., replication by imitation, in a device-controlled mode selection algorithm. To evaluate the performance of the proposed mode selection algorithm, we conduct simulations to compare it with three baseline schemes, including an approach based on maximum signal-to-interference-plus-noise, a distance-based approach, and a random approach. As shown in the simulation results, the proposed approach achieves higher utilities than the baseline schemes.
Factors Influencing Intention to Use Cloud Storage Services Amongst Postgraduate Students in Malaysian Technical Universities

The purpose of this research is to supply empirical evidence about the acceptance of Cloud Storage Services (CSS), by attempting to build an enhanced research framework with based on the Technology Acceptance Model (TAM) to identify factors that affect postgraduate students' intentions to use CSS. Factors examined are cloud storage service support, cloud storage self-efficacy, perceived usefulness and perceived ease of use on intention to use CSS. Using convenience sampling method, a total of 219 postgraduate students from 4 Malaysian technical universities participated in the study. Structured equation modelling was used to analyse the data and findings indicate that CSS support have a significant positive relationship with “perceived usefulness”, and “cloud storage self-efficacy” have significant positive relationship on the “perceived ease of use”. Both “perceived usefulness” and “perceived ease of use” have a significant relationship on students' intention to use CSS. The findings of this study can help the service providers to develop successful strategic plans for usage of CSS. Universities should also have policy and guidelines in using services to ensure the security when access information from intranet.

Normative Reference Values for High School-Aged American Football Players: Proagility Drill and 40-Yard Dash Split Times.

McKay, BD, Miramonti, AA, Gillen, ZM, Leutzinger, TJ, Mendez, AI, Jenkins, NDM, and Cramer, JT. Normative reference values for high school-aged American football players: Proagility drill and 40-yard dash split times. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this short report was to provide test- and position-specific normative reference values for the 10- and 20-yd split times (10YD and 20YD) during the 40-yd dash (40YD) as well as 10-yd split times during the proagility drill (PA) based on a large, nationally representative sample of high school-aged American football players in their freshman, sophomore, and junior classes. Cross-sectional performance data were obtained from 12 different high school American football recruiting combines between March 7, 2015, and January 9, 2016, across the United States. The sample included (n = 7,478) high school-aged American football athletes in their freshman (n = 1,185), sophomore (n = 2,514), and junior (n = 3,779) classes. Each player self-classified their American football positions as defensive back, defensive end, defensive linemen, linebacker, offensive linemen (OL), quarterback (QB), running back, tight end, or wide receiver. The results of the freshman, sophomore, and junior class were aggregated to generate test- and position-specific normative values. Mean differences were found among classes for all positions and all measurements (p ≤ 0.05) except for OL and QB PA split time (p > 0.05). Greater percent differences for all 3 variables were observed between freshman and sophomore years than between sophomore and junior years. These normative reference values will be useful for athletes, parents, coaches, and high school strength and conditioning professionals to set realistic goals for young American football athletes.
