Study on implementation of Secure HTML5 Local Storage

HTML5 has developed not to have browser dependancy considering interoperability as same as maintaining compatability with lower versions of HTML. HTML5, the newest web standardization is on going of being structured. Along with the smart phone boom, HTML5 is spotlighted because it can be applied to cross platforms in mobile web environments. Specially the local Storage that has been listed in new features in HTML5 supports offline function for web application that enables web application to be run even when the mobile is not connected to 3G or wifi. With Local storage, development of server-independent web application can be possible. However Local storage stores plaintext data in it without applying any security measure and this makes the plaintext data dangerous to security threats that are already exist in other client side storages like Cookie. In the paper we propose secure Local storage methods to offer a safe way to store and retrieve data in Local storage guaranteeing its performance. Suggested functions in this paper follow localStorage standard API and use a module that provide cryptographic function. We also prove the efficiency of suggested secure Local storage based on its performance evaluation with implementation.
A transformerless five level cascaded inverter based single phase photovoltaic system

This paper describes the current control method and the switching scheme of a cascaded five level inverter based grid connected single phase photovoltaic system. For the current control a dual polarised ramptime zero average current error control method is applied, which provides good current regulation, and a narrow ripple current frequency band. Simulation results which demonstrate the method are presented. The redundant inverter states of the five level cascaded inverter allow for a cyclic switching scheme which minimises the switching frequency, equalises stress evenly on all switches and minimises the voltage ripple on the DC capacitors. Simulation and experimental results of a multi carrier PWM voltage controller showing the effectiveness of the switching scheme are presented.
Evaluation of Risk Management Strategies for a Low-Cost, High-Risk Project

This paper summarizes work in progress to define and implement a risk management process tailored to a low-cost, high-risk NASA mission–the Microrover Flight Experiment (MFEX, commonly called the Mars microrover). The tailored risk management process is described along with the extensive data collection, documentation, and quantitative analyses that are being performed. This effort has the explicit purpose of trying, evaluating, and documenting new risk management techniques so as to help not only the MFEX mission, but future missions in the same risk class.
A neural network approach to failure diagnostics for underwater vehicles

The author addresses the proposed use of Kalman filters and artificial neural networks to provide the detection and isolation of impending system failures. Such system health diagnosis is necessary for the overall success of mission controllers for autonomous underwater vehicles (AUVs). Two examples of network designs are given. The first addresses the identification of anomalous changes to the vehicle's acceleration behavior resulting from possible propulsion system changes or loss of propulsion efficiency from fouling. The second example relates to the identification of excessive frictional loads in the propulsion drive train that may cause motor failure. In each case, the training method and the resulting decision surface characterization of the networks so designed are described. <<ETX>>
A comparison of two scoring procedures with the NASA task load index in a simulated flight task

Two issues which pertain to NASA task load index (TLX) application procedures and scoring techniques were investigated. One issue concerned the procedure used to combine ratings on the TLX dimensions into one overall rating. The second issue dealt with the delay of TLX workload ratings for a time period subsequent to completion of a rated flight segment. Participants flew several simulated flight missions under three difficulty levels and rated the workload either immediately following a flight segment or after 15-minute or 48-hour delays. Overall workload ratings were derived through the use of either a weighted or an unweighted combination of TLX dimensions. The results of the scaling techniques were highly correlated (r=0.94), and analyses revealed no differences between the resulting scaling procedures. It was found that the time-consuming use of weighting scales is not necessary and that delaying TLX reports up to 15 minutes does not significantly interfere with recall of workload ratings. <<ETX>>
Adoção de Práticas de Gestão de Segurança da Informação: um estudo com gestores públicos

This paper aims to identify which factors influence the adoption of management security information advanced practices by state public managers in Brazil. Argues that information has increasingly proeminent role in organizations, being imperative to use management techniques that give greater security to its use. The theoretical reference of the paper was based on the postulates of the Technology Acceptance Model - TAM authored by Davis, Bagozzi, Warshaw (1989) and the procedures recommended in accordance with ISO/IEC 27011. Methodologically, was adopted a quantitative aproach of analysis using descriptive and inferential techniques, like measures of central tendency, factor analysis and linear regression. The results show that the average age of managers is approximately 43 years and that 70% have some type of postgraduated course completed. About the results of inferential analysis, the constructs "perceived usefulness of adopting safety practices", "attitude toward the safety practices" and "intention to use safety practices" confirmed to be influential in the acceptance of PNAGE's state managers on the practice more advanced access control and control of human resources for information security. Only the construct 'ease of use' was not a good predictor of the level of agreement with the practices recommended by ISO / IEC 27001. It is hoped that this study can support future information security policies, especially when formulated for adhesion to the managers of this research focus areas (planning and management).
Characterization of methods for surveillance by optimality

Different criteria of optimality are discussed. The shortcomings of some criteria of optimality are demonstrated by their implications. The correspondences between some criteria of optimality and some methods are examined. The situations and parameter values for which some commonly used methods have certain optimality properties are thus illuminated. A linear approximation of the full likelihood ratio method, which satisfies several criteria of optimality, is presented. This linear approximation is used for comparisons with the exponentially weighted moving average method. Via these comparisons it is possible to illuminate the influence of different criteria of optimality on the "optimal" parameter of a method. A uniform presentation of methods, by expressions oflikelihood ratios, facilitates the comparisons between methods.

Using Multi-Function Constructed Wetland for Urban Stream Restoration

In 2007, a 2.8-ha multi-function constructed wetland was successfully built in Pingtung County, Taiwan to improve the water quality of local stream and ecosystem of the surrounding environment. The mean inflow rate was approximately 1,350 m3/day. The major influents of the wetland come from the local drainage ditches and streams mainly containing returned water from upstream farmlands and secondary wastewater from hog farms located in the upper catchment of the wetland. Thus, the influents contain moderate to high concentrations of organics and nutrients. The mean measured hydraulic loading rate, hydraulic retention time, water depth, and total volume of wetland system were 0.1 m/day, 5.5 days, 0.7 m, and 7,800 m3, respectively. In this study, water, sediment, and plant samples were collected and analyzed quarterly for each wetland basin during the two-year investigation period. Results show that more than 77% of total coliforms (TC), 78% of biochemical oxygen demand (BOD), 88% of total nitrogen (TN), and 96% of ammonia nitrogen were removed via the constructed wetland system. Thus, the wetland system has a significant effect on water quality improvement and is able to remove most of the pollutants from the local stream through natural attenuation mechanisms. Except for stream water quality improvement and rehabilitating the natural ecosystem, this wetland also offers more water assessable eco-ponds and eco-gardens for public. This constructed wetland has become one of the most successful multi-function constructed wetlands in Taiwan.
Influence of the Off the Street, On the Ball Midnight Football Program on Physical Fitness, Self-Esteem and Quality of Life in Youth-at-Risk

The main aim of this study was to investigate the influence of the “Off the Street, On the Ball” Midnight Football Program on physical fitness components, self-esteem and perception on quality of life between baseline and post-program in youth-at-risk. A total of 58 male participants in the pilot project “Off the Street, On the Ball” Midnight Football Program organized by the Social Responsibility Department, Asian Football Confederation (AFC) were recruited as the subjects of this study. They were aged 14-19 years, with a mean age of 16.72 (SD= 1.24) years. Instrumentations employed in this study were Yo-Yo Intermittent Test, Single Sprint Test, and Balsom Agility Test to measure aerobic endurance, speed and agility of the subjects on baseline and post-program. Two questionnaires were administered, the Influence on Quality of Life Scale (IQLS) and Rosenberg Self-Esteem Scale (RSES) to collect perception on quality of life and self-esteem on baseline and post-program. Between the baseline and post-program, all subjects were divided into eight groups followed four weeks of soccer-specific periodized training programme and controlled by certified coach assigned to them. Results of present study revealed that all physical fitness components (aerobic endurance, speed and agility) were significant difference between baseline and postprogram at p < . 05. For the self-esteem, results indicated significant differences favouring the post-program (t=-19.82, df=91, p<.05). An analysis of the individual items on the IQLS indicated that vast majority of the subjects either agreed or strongly agreed that involvement in the midnight football program positively influenced their perception on quality of life. Overall, the results of the current study lend additional support to the use of football program to develop positive self-esteem and creating opportunities to experience positive perception on quality of life. Thus, positive self-esteem and positive perception on quality of life are significantly more likely to reduce social risk factors for juvenile delinquency and serious antisocial behaviour in youth-at-risk in Asia, especially in Malaysia.
Research of the VLF Atmospheric Noise Statistical Prediction

The nature of the vlf atmospheric noise can have a dramatic effect on the performance of the vlf receivers. To understanding how the receivers will perform in different locations and time, the key is proper predicting the critical parameters of the vlf atmospheric noise. Based on the purpose, according to the historical data and the corresponding frequency and parameter variation chart, established the data fitting algorithm to predict the critical parameters of the vlf atmospheric noise. By simulating and comparing with the measured data, testified the effectiveness of the vlf atmospheric noise prediction method. To grasp the change rule of critical vlf noise parameters with time and geographical position is helpful to improve the vlf communication effectiveness.
Damage identification in civil engineering structures utilizing PCA‐compressed residual frequency response functions and neural network ensembles

This paper presents a non‐destructive, global, vibration‐based damage identification method that utilizes damage pattern changes in frequency response functions (FRFs) and artificial neural networks (ANNs) to identify defects. To extract damage features and to obtain suitable input parameters for ANNs, principal component analysis (PCA) techniques are applied. Residual FRFs, which are the differences in the FRF data from the intact and the damaged structure, are compressed to a few principal components and fed to ANNs to estimate the locations and severities of structural damage. A hierarchy of neural network ensembles is created to take advantage of individual information from sensor signals. To simulate field‐testing conditions, white Gaussian noise is added to the numerical data and a noise sensitivity study is conducted to investigate the robustness of the developed damage detection technique to noise. Both numerical and experimental results of simply supported steel beam structures have been used to demonstrate effectiveness and reliability of the proposed method.

Design of robust signal and clock networks

As technology scales down into the nanometer region new design challenges emerge. Wire delays become the performance bottleneck in VLSI circuits. Copper is introduced as new wiring material because of its low sheet resistivity, hence low signal propagation delay. The main defect mechanism shifts from shorts to opens due to the different manufacturing process for copper wires. Open defects limit functional yield. Parametric yield decreases because of timing uncertainties emerging from manufacturing variation. Clock skew variation becomes critical because it may shorten the cycle length of the critical path. The variation of signal nets has to be considered simultaneously avoiding overly pessimistic designs. Design techniques which reduce the variation of design parameters avoid over design and increase parametric yield.
Local spectral and temporal characterizations of a wave

Many waves exhibit characteristics that depend on time and/or frequency. For example, the frequencies of a pulse propagating in a dispersive medium travel at different velocities. This kind of dependency gives rise to the need for joint time- frequency analysis and methods for describing the local temporal and spectral nature of waves, particularly pulses and transients. Useful concepts arising for this description from time-frequency theory are the average frequency at each time of a wave, and the spread about that average. These quantities are obtained as conditional moments of a time-frequency density (TFD). We explore the conditional variances of some common TFDs, and determine when these are positive (which isn't always the case). We also investigate local characteristics of a wave, in terms of these conditional moments, and show through experimental results that they robustly characterize the time-frequency behavior of transients and pulses.
DESIGN OF SERIES FED PRINTED ARRAYS

A new approach to the design of series-fed printed arrays is proposed, taking into account both the mutual coupling between the patches and the patch-feedline interaction. This approach relies on a small set of design equations, describing in a concise way the array behaviour. Each patch, and the mutual coupling, is modelled using an accurate form of the transmission-line model. The model parameters, as well as the feed-structure ones, enter in the design equations thus allowing an effective array design. Both pencil-beam and shaped-beam aperture distributions can be synthesized. The presented approach has been validated using both Method of Moments simulations and experimental responses.
Application of datamining techniques for power cable diagnosis

The insulation ageing is related to the absolute age, the type, the history and the laying conditions of a network (sub) component. The processing of the information about condition assessment in combination with technical specifications as well as the history of maintenance actions is of importance in decision support for asset management. In this paper aspect of generic approach in use of database support for maintenance of distribution power cables is discussed. In particular the knowledge rules generation and datamining as important asset management tools are discussed in this paper.
High-bandwidth 220 GHz experimental radar

An experimental radar at 220 GHz has been developed which is capable of delivering an instantaneous bandwidth of 8000 MHz. The solid-state radar uses an FM-CW waveform. The development is based on experience with a 94 GHz broadband measurement radar. The data undergo an ISAR imaging process to derive high-resolution scattering centre distributions for targets measured in tower/turntable configuration. High-resolution processing algorithms have been developed which result in scattering centre distributions with a resolution better than 2 cm at ranges of and exceeding 200 m. The radar will be used for investigations on target signatures of small objects for stand-off detection of concealed weapons and other threat material.
Estimation of the traffic accidents costs in Serbia by using dominant costs model

Abstract This paper presents estimation of the traffic accident costs in Serbia, based on original dominant costs model. Dominant costs model uses human capital approach and this model is developed for simple and quick calculation of the traffic accidents costs, because other simple methods as 1 million rules, are not suitable for estimation of the traffic accident costs in the countries with a low GDP per capita. Knowing the costs of traffic accidents is of crucial importance for establishing traffic safety to the level defined by the size of costs made as a consequence of unsafely. So, politicians, decision makers and stakeholders in the field of traffic safety often need quick estimation of the traffic accident costs and economic effects of the particular measures which are applied for decreasing the number and severity of traffic accidents. The estimation of the level of the traffic accidents costs in Serbia, based on the official data (from the Ministry of Interior of the Republic of Serbia) about tr.
PD-1 overexpression determines the disproportion of circulating Th1/Th17/Treg cells and clinical outcome of multiple myeloma

Background The role of particular immune checkpoints in the induction of systemic immunosuppression, which severely complicates the clinical course and prognosis in multiple myeloma (MM), is still unresolved. Only a subset of MM patients treated with checkpoint inhibitors derive benefits, suggesting differential participation of relevant receptors in the inhibitory signaling pathway. This study was undertaken to identify an immune checkpoint playing a key role in systemic T-cell-related immune deficiency in MM in the context of Th1/Th17/Treg cell distribution.Methods We used flow cytometry assay to examine the expression of PD-1, BTLA, and CTLA-4 in peripheral blood (PB) CD4 + , CD4 + CD127 + (Teff), and CD4 + CD127 - (Treg) T cell subsets as well as the balance of Th1/Th17/Treg cells. The study group consisted of 40 untreated (newly diagnosed or relapsed/refractory) myeloma patients in different clinical stages. The obtained results were compared to those observed in 20 healthy controls.Results Among immune checkpoints studied, only PD-1 was expressed on a significantly increased proportion of circulating Teff and Treg cells in MM; we also noted a positive correlation of PD-1 expression with clinical stage. Furthermore, the percentage of PD-1 + Teff cells was correlated with beta2-microglobulin serum concentration and shorter overall survival (OS). We also found higher Th17 and Treg compartments in PB irrespectively of tumor stage; however, in some studied subsets, a decrease at stage III was observed. Moreover, PB Th1 deficit (more pronounced in advanced disease) was also observed. Except for the PD-1 + Teff subset, none of the examined cell population was related to OS.Conclusions The study indicates that PD-1 expression on circulating T cell subsets may contribute to the imbalance in PB Th1/Th17/Treg cell distribution and systemic immunosuppression in MM. PD-1 seems to be the only immune checkpoint determining clinical behavior of patients, thereby strengthening the therapeutic potential for inhibitors.
A Cascaded Multi- and Single-Mode Fiber Transporting for Laser Beam

A model to calculate the butt-joint coupling efficiency between a multi-mode fiber to a single-mode fiber is presented based on a mode field coupling theory. The dependence of the coupling efficiency between the multi- and single-mode fibers on the core radius of the multi-mode fiber is investigated. A experiment is conducted with 532nm laser to measure the butt joint coupling efficiency of a multi-mode fiber to a single-mode fiber. Good agreement is obtained between the experimental results and the theoretical predictions. A cascaded multi- and single-mode fiber relay system is proposed to transport a laser beam with high power and good beam quality.
Switched capacitor system for automatic series battery equalization

A clocked switched-capacitor circuit can exchange charge between adjacent batteries in a series string. This exchange drives all batteries to identical voltages, without regard to component values, battery technology, or state of charge. This equalization process can proceed while the batteries are in use or under charge, or separately. Transformer-based and transformerless implementations are given, and results of experimental tests are provided. The process is much faster and less stressful than the conventional approach, and is simpler than some active approaches.
