Dual-band integrated Wi-Fi PAs with load-line adjustment and phase compensated power detector

A load-line adjusted 2.4GHz PA is designed to operate in full power (18dBm/150mA) & mid power (7dBm/19mA) in OFDM with ~130mA saving. To improve network throughput in dense environment with per-packet TX power control, the phase-compensated power detector achieves ±0.6dB accuracy for the entire 5GHz band over 2:1 VSWR and 16dBm±0.25dB over channel flatness in VHT80MCS9. The chip area is 0.21mm2 for load-line adjusted 2.4GHz PA and 0.13 mm2 for 5GHz PA with power detector.
Event‐related brain activity associated with auditory pattern processing

ONE of the basic properties of the auditory system is the ability to analyse complex temporal patterns. Here, we investigated the neural activity associated with auditory pattern processing using event-related brain potentials. Participants were presented with a continuously repeating sequence of four tones with rare changes in either the frequency or timing of one of the tones. Both frequency- and time-deviant sounds generated mismatch negativity (MMN) waves that peaked at midline central electrode sites and inverted in polarity at inferior temporal and occipital sites, consistent with generators in the supratemporal plane. The MMN scalp topography was similar for the frequency- and time-deviant stimuli, suggesting that both spectral and temporal relations among elements of an auditory pattern are encoded in a unified memory trace.
Rolling boles, optimal XML structure integrity for updating operations

While multiple techniques exist to utilize the tree structure of the Extensible Markup Language(XML) regarding integrity checks, they all rely on adaptions of the Merkle Tree: All children are acting as one slice regarding the check-sum of one node with the help of an one-way hash concatenation. This results in postorder traversals regarding the (re-)computation of the integrity structure within modification operations. With our approach we perform nearly in-time updates of the entire integrity structure. We therefore equipped an XHash-based approach with an incremental hash function. This replaces postorder traversals by adapting only the incremental modifications to the check-sums of a node and its ancestors. With experimental results we prove that our approach only generates a constant overhead depending on the depth of the tree while native DOMHash implementations produce an overhead based on the depth and the number of all nodes in the tree. Consequently, our approach called Rolling Boles generates sustainable impact since it facilitates instant integrity updates in constant time.
Laboratory experiments for exploring the surface plasmon resonance

The surface plasmon wave is a surface wave confined at the interface between a dielectric and a metal. The excitation of the surface plasmon resonance (SPR) on a gold thin film is discussed within the Kretschmann configuration, where the coupling with the excitation light is achieved by means of a prism in total reflection. The electromagnetic principles are detailed and a simple experimental setup is described that can be used for laboratory experiments for senior students in the third or fourth year of university. This experiment allows accurate determination of the angle of plasmon extinction and discussion of the principles of biosensors based on the SPR. A slight modification of the setup allows the investigation of the dependence of SPR on wavelength and illustrates the damping of SPR due to its coupling with the interband transitions of the gold thin film.
Energy-aware application scheduling based on genetic algorithm

As cloud computing is expected to expand rapidly in the coming years, the large-scale computing and data centers are becoming more and more widespread in the world. Energy consumption of these distributed systems has become a urgent problem and received much attention. Application Scheduling can alleviate this problem by reducing the number of running nodes and effectively maximizing total system efficiency. This paper focuses on scheduling applications in large-scale data centers using genetic algorithm. Specifically, we present the design and implementation of the cost function, the modification of the genetic operators and the choice of the data transition weight. The algorithm is studied via simulation and implementation in a large-scale data center. Test results and performance discussion justify the feasibility of the scheduling algorithm. From the results, we know that the proposed application scheduling method can be useful in practice, which can reduce the running nodes and minimize the cost of data transferred among the nodes efficiently.
AN INVESTIGATION OF CONTEXT-DEPENDENT AND HYBRID MODELING TECHNIQUES FOR VERY LARGE VOCABULARY ON-LINE CURSIVE HANDWRITING RECOGNITION

This paper addresses a very challenging topic in on-line handwriting recognition. It deals with the problem how to further improve a baseline very large vocabulary HMM-based handwriting recognition system with a vocabulary size of 200.000 German words. The use of sophisticated HMM-technology allows the construction of such a baseline system. It is however an extremely difficult task to further improve such a system, because the very large vocabulary size leads to implementation problems related to memory and search space limitations. The paper investigates some advanced modeling techniques for further improvement of such systems and demonstrates how several special effects of these techniques can be exploited in order to increase the recognition performance without enlarging the requirements for memory allocation or search space. This is mainly achieved by introducing a novel hybrid Connectionist/HMM-approach to handwriting recognition, based on the use of so-called Maximum Mutual Information Neural Networks (MMINN) which serve as neural vector quantizer for the HMM-based handwriting recognition system. The result of this investigation is one of the first available 200k writer-dependent on-line handwriting recognition systems, which can be demonstrated on a PC and has achieved recognition rates of more than 90% for several test writers.
A Research Model for Investigating Human Behavior Related to Computer Security

Computer security issues have typically been approached from the perspective of building technical countermeasures to reduce risk. Recently, researchers have recognized that computer users play an important role in ensuring secure systems by implementing those technical countermeasures. As a means of encouraging safe computing practice, user training and awareness have been touted. However, simply providing training and awareness does not ensure that users will always use safe practices. This paper introduces a model of user behavior that emphasizes the factors relating to the user’s perception of risk and the choice based on that perception. As research in progress, we also briefly describe an ongoing study to further investigate this model. We will present results from this study at the conference.
Innovating to Create IT-Based New Business Opportunities at United Parcel Service

Although the role of information technology (IT) in enabling competitive advantage is well established, many organizations still find it a challenge to convert IT investments and assets into new business opportunities. The case study in this article describes how United Parcel Service (UPS) has used IT investments to create IT assets and IT competencies, which have led to business capabilities, then to new business opportunities. These opportunities were identified by examining the value network that links UPS’s internal value chain with its customers to uncover information and IT needs of various business partners.

In addition, advanced procedure for SIP based seamless handover in heterogeneous network using congestion detection was described. Its performance was evaluated using the described simulation model. The results have shown that, by using the CAHP C procedure, we can significantly improve the user experience for VoIP application when performing seamless handover in heterogeneous networks.
Assessment of the Relationship between Lipid Parameters and Obesity Indices in Non-Diabetic Obese Patients: A Preliminary Report

Background The aim of this cross-sectional study was to examine the relationship between obesity and lipid markers. Material/Methods We divided 66 non-diabetic adult obese patients (mean age: 55.8±11.6 years) into 3 groups according to body mass index (BMI). All patients were measured for waist circumference (WC), hip circumference (HC), body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body adiposity index (BAI), and visceral adiposity index (VAI). Serum levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) were determined, and lipid indices TC/HDL, LDL/HDL, and TG/HDL were also estimated. Results TC and LDL-C in Group III were lower than in Group I (5.0±1.0 vs. 6.0±1.0 mmol/L, and 2.9±0.9 vs. 3.8±1.2 mmol/L; p<0.05 for both). Negative correlations were found between: BMI and TC, LDL, and HDL (r=−0.291; r=−0.310, r=−0.240, respectively); and WC, WHR, VAI, and HDL (r=−0.371, r=−0.296, r=−0.376, respectively). Positive correlations were found between WC, WHR, and TG/HDL (r=0.279, r=0.244, respectively) and between VAI and: TC (r=0.327), TG (r=0.885), TC/HDL (r=0.618), LDL/HDL (r=0.480), and TG/HDL (r=0.927). Conclusions Obesity is associated with lipid disturbances, especially with HDL-C reduction, in obese non-diabetic patients. VAI is strongly related to lipid profile and thus may be the most valuable obesity index in obese patients with dyslipidemias.
UV‐induced DNA damage and melanin content in human skin differing in racial/ethnic origin

DNA damage induced by UV radiation is a critical event in skin photocarcinogenesis. However, the role of racial/ethnic origin in determining individual UV sensitivity remains unclear. In this study, we examined the relationships between melanin content and DNA damage induced by UV exposure in situ in normal human skin of different racial/ethnic groups, phototypes, and UV sensitivities. The minimal erythema dose (MED) was established for each subject exposed to UVA/UVB radiation, and skin was biopsied before as well as 7 min, 1 day, and 1 wk after UV exposure. There was great variation among individuals in the amount of DNA damage incurred and rates of its removal. The results show that after exposure to 1 MED of UV, the skin of subjects from all groups suffered significant DNA damage, and that increasing content of constitutive melanin inversely correlated with the amount of DNA damage. It is clear from these results that measured erythemal UV sensitivity of the skin (MED) is a more useful predictor of DNA photodamage than is racial/ethnic origin or skin phototype and that rates of DNA damage removal following UV radiation may be the critical determinant of the UV sensitivity (including predisposition to cancer) of the skin.
A Dynamic Graph Watermark Scheme of Tamper Resistance

A novel approach of dynamic graphic software watermark is proposed. In this scheme, many fake watermarks created through encoding multi-constant, which's structure is similar to the only true one's, are introduced to enhance the stealth and anti-attack ability of dynamic graph watermark and keep software from sabotage. Meanwhile, a detailed analysis in theory is made in terms of the principle, feasibility and merits of this approach. A series of tests are made on the basis of the prototype system, analyzing the two sub-systems separately about their validity, robustness and performance overload caused by watermark embedding. Moreover, bit-rate of the three graph watermark structures in the system is analyzed in theory.
OBPR Guidance Note – Cost-Benefit Analysis July 2013 Guidance note-Cost-benefit analysis in Regulation Impact Assessment

The Australian Government is committed to the use of cost-benefit analysis (CBA) to assess regulatory proposals to encourage better decision making. A CBA involves a systematic evaluation of the impacts of a regulatory proposal, accounting for all the effects on the community and economy: not just the immediate or direct effects, financial effects or effects on one group. It emphasises, to the extent possible, valuing the gains and losses from a regulatory proposal in monetary terms.
Gender Equity in Materials Science and Engineering

At the request of the University Materials Council, a national workshop was convened to examine 'Gender Equity Issues in Materials Science and Engineering. ' The workshop considered causes of the historic underrepresentation of women in materials science and engineering (MSE), with a goal of developing strategies to increase the gender diversity of the discipline in universities and national laboratories. Specific workshop objectives were to examine efforts to level the playing field, understand implicit biases, develop methods to minimize bias in all aspects of training and employment, and create the means to implement a broadly inclusive, family-friendly work environment in MSE departments. Held May 18-20, 2008, at the Conference Center at the University of Maryland, the workshop included heads and chairs of university MSE departments and representatives of the National Science Foundation (NSF), the Office of Basic Energy Sciences of the Department of Energy (DOE-BES), and the national laboratories. The following recommendations are made based on the outcomes of the discussions at the workshop. Many or all of these apply equally well to universities and national laboratories and should be considered in context of industrial environments as well. First, there should be a follow-up process by which the University Materials Council (UMC)more » reviews the status of women in the field of MSE on a periodic basis and determines what additional changes should be made to accelerate progress in gender equity. Second, all departments should strengthen documentation and enforcement of departmental procedures such that hiring, promotion, compensation, and tenure decisions are more transparent, that the reasons why a candidate was not selected or promoted are clear, and that faculty are less able to apply their biases to personnel decisions. Third, all departments should strengthen mentoring of junior faculty. Fourth, all departments must raise awareness of gender biases and work to eliminate hostile attitudes and environments that can make academic and national laboratory careers unattractive to women. Fifth, with respect to raising awareness among faculty, staff and students, a new type of training session should be developed that would be more effective in conveying the facts and consequences of gender bias than the conventional presentations typically available, which seem not to be highly effective in changing attitudes or behaviors. Sixth, it is proposed that the UMC establish a certification of 'family-friendly' or 'gender equivalent' institutions that would encourage organizations to meet standards for minimizing gender bias and promoting supportive work environments. Seventh, novel approaches to adjusting job responsibilities of faculty, staff, and students to permit them to deal with family/life issues are needed that do not carry stigmas. Finally, faculty and national laboratory staff need to promote the benefits of their careers to women so that a more positive image of the job of materials scientist or materials engineer is presented. « less
Life-course and entry to entrepreneurship:embedded in gender and gender-egalitarianism

ABSTRACT Prior research has suggested that low gender egalitarianism results in a gender gap in entrepreneurship participation, as it provides men and women with different opportunities and constraints. However, this research has primarily relied on an unrealistic assumption, namely that gender-related opportunities and constraints occur evenly throughout different life stages. This paper details an institutional life-course model that explains gender-related patterns in individuals’ propensity to enter entrepreneurship and contingencies related to the level of gender-egalitarianism in society and individuals’ life stages. We test our conceptual model on a unique integrated dataset from the Global Entrepreneurship Monitor and the World Value Survey, encompassing a total of 672,781 adults in 71 countries.
Decision-Feedback Closest Lattice Point Search for UMTS HSPA System

This letter considers a low-complexity multiuser detection based on the closest lattice point search (CLPS) for high speed packet access (HSPA) system. Instead of attempting to solve the ML detection problem in the presence of intersymbol and inter-cell interference, we utilize interference cancelled chips obtained from a bidirectional decision feedback operation to detect symbols. As a result, the worst case complexity of the CLPS is bounded to a controllable level irrespective of multipath spans. From the simulation on single and multi cell downlink communications in HSPA systems, we show that the proposed method offers substantial performance gain over conventional RAKE and MMSE equalizer.

Applying Interface-Contract Mutation in Regression Testing of Component-Based Software

Regression testing, which plays an important role in software maintenance, usually relies on test adequacy criteria to select and prioritize test cases. However, with the wide use and reuse of black-box components, such as reusable class libraries and COTS components, it is challenging to establish test adequacy criteria for testing software systems built on components whose source code is not available. Without source code or detailed documents, the misunderstanding between the system integrators and component providers has become a main factor of causing faults in component-based software. In this paper, we apply mutation on interface contracts, which can describe the rights and obligations between component users and providers, to simulate the faults that may occur in this way of software development. The mutation adequacy score for killing the mutants of interface contracts can serve as a test adequacy criterion. We performed an experimental study on three subject systems to evaluate the proposed approach together with four other existing criteria. The experimental results show that our adequacy criterion is helpful for both selecting good-quality test cases and scheduling test cases in an order of exposing faults quickly in regression testing of component-based software.
Directional entropy feature for human detection

In this paper we propose a novel feature, called directional entropy feature (DEF), to improve the performance of human detection under complicated background in images. DEF describe the regularity of region by computing the entropy value of edge pointspsila spatial distribution in specific direction, so DEF has the discriminating power for regular and random pattern. We combine histogram of oriented gradient (HOG) feature with DEF to construct a human detection classifier to test DEFpsilas performance. Experimental results show that DEF can help HOG to decreases false alarms caused by random complicated and rigid shaped background.
Toward Effective Movie Recommendations Based on Mise-en-Scène Film Styles

Recommender Systems (RSs) play an increasingly important role in video-on-demand web applications -- such as YouTube and Netix -- characterized by a very large catalogs of videos and movies. Their goal is to filter information and to recommend to users only the videos that are likely of interest to them. Recommendations are traditionally generated on the basis of user's preferences on movies' attributes, such as genre, director, actors. Preferences on attributes are implicitly detected by analyzing the user's past opinions on movies. However, we believe that the opinion of users on movies is better described in terms of the mise-en-scène, i.e., the design aspects of a film production affecting aesthetic and style. Lighting, colors, background, and movements are all examples of mise-en-scène. Although viewers may not consciously notice film style, it still affects the viewer's experience of the film. The mise-en-scène highlights similarities in the narratives, as filmmakers typically relate the overall film style to reflect the story, and can be used to categorize movies at a finer level than with traditional film attributes, such as genre and cast. Two films may be from the same genre, but they can look different based on the film style. In this paper, we present an ongoing work for the development of a novel application that offers a personalized way to search for interesting multimedia content. Instead of using the traditional classifications of movies based on attributes such as genre and cast, we use aesthetic movie features derived from film styles as determined by filmmaker professionals. Stylistic features of movies are extracted with an automatic video analysis tool and are used by our application to generate personalized recommendations and to help users in searching for interesting content.
A Lithium-ion battery energy storage system using a bidirectional isolated DC-DC converter with current mode control for More Electric Aircraft

The present trends in the aircraft industry is a shift towards a “More Electric” architecture, in which electrical power drives aircraft flight surfaces. With the increase in electrical power requirement, a high energy density battery energy storage system (BESS) is required in a More Electric Aircraft (MEA). This paper describes the design and operation of a 50 kW, 6.4 kWh Lithium ion BESS in detail, wherein the circuit parameters are designed considering the required power sharing and the limitation of ripple in voltage and current. A current mode control technique is proposed for the integration of the proposed high energy density Li-Ion BESS with 270 V DC power distribution bus. A bidirectional isolated DC-DC converter is used for the integration. In order to achieve the high performance of the isolated bi-directional DC-DC converter, the system output voltage must maintain good tracking of its reference command, despite transient events and varying operating conditions. The proposed battery configuration is verified under different dynamic conditions using the proposed current mode control with variations in the output current (load). The circuit modeling is done in PSIM simulation environment, and simulation results are presented and discussed in the paper.
Analysis of InAs-Si heterojunction nanowire tunnel FETs: Extreme confinement vs. bulk

Extremely narrow and bulk-like p-type InAs-Si nanowire TFETs are studied using a full-band and atomistic quantum transport simulator based on the sp3d5s* tight-binding model and a drift-diffusion TCAD tool. As third option, the WKB approximation has been adapted to work in heterostructures through a careful choice of the imaginary dispersion. It is found that for ultra-scaled InAs-Si nanowire TFETs, the WKB approximation and the quantum transport results agree very well, suggesting that the former could be applied to larger hetero-TFET structures and considerably reduce the simulation time while keeping a high accuracy.
