Design and performance analysis of adaptive neuro fuzzy controller for load frequency control of multi-power system

This paper presents an adaptive neuro fuzzy (ANFIS) based load frequency control for multi-area non-reheat turbine power system. It can handle the non-linearity of the system and react to situation faster than the conventional controller. The changes in frequency and Tie-line power are subjects be controlled for 3-area power system. The system response with proposed controller is compared to that of with conventional controllers presented in literature. The comparison is carried-out in terms of over-shoot, under-shoot and settling-time of frequency and tie-line power. It is proposed that the intelligent controller (ANFIS) provides encouraging result as compared that of with PID controllers in literature. The robustness of the proposed controller is considered for a wide range of change in load.
A Spectrum Selection Method Based on Recurrent Neural Network for OTHR

A spectrum selection method for OTHR is presented. We first establish electromagnetic environment database using the data that frequency monitoring system have observed. Then we define spectrum selection consisting of two steps: spectrum state prediction and frequency band selection. Finally, we introduce a method based on recurrent neural network (RNN) for spectrum prediction which has a good effect on the short-term fluctuations of the band status sequence. Experiment with observed data are provided to demonstrate the effectiveness of the proposed method.
Do Color Blindness and Multiculturalism Remedy or Foster Discrimination and Racism?

This article offers insight from psychological science into whether models of diversity (e.g., color blindness and multiculturalism) remedy or foster discrimination and racism. First, we focus on implications of a color-blind model. Here, the literature suggests that while color blindness appeals to some individuals, it can decrease individuals’ sensitivity to racism and discrimination. Furthermore, the literature suggests that, with some exceptions, color blindness has negative implications for interracial interactions, minorities’ perceptions and outcomes, and the pursuit of diversity and inclusion in organizational contexts. Second, we examine circumstances under which a multicultural approach yields positive or negative implications for interracial interactions, organizational diversity efforts, and discrimination. The research reviewed coalesces to suggest that while multiculturalism generally has more positive implications for people of color, both models have the potential to further inequality.
The benefits of search costs in multiagent exploration

Humans and software agents alike spend considerable time and effort in searching. Search enables finding the things that better fit and agent's goals. But search can also be a costly process. Search costs can either come in the form of direct monetary payments, or in the form of time and resources spent. In general, the searcher must balance between the benefits provided by longer and broader search, on the one hand, and the associated increased cost, on the other.
A NEW METHOD FOR SOLVING THE PERIODIC STEADY STATE OF NONLINEAR CIRCUITS

The periodicity condition of state variable ensures the circuit periodic steady state. Circuits with linear dynamic elements and nonlinear resistors can be solved iteratively using the method of equivalent sources, by replacing the nonlinear resistors with controlled sources having constant resistance throughout the iterations. The final values of the state variables appear as affine functions of their initial values and only the additive term changes iteratively. By imposing a periodicity condition the initial values of the state variables are obtained by solving a linear system of equations in which the system matrix remains unchanged during each iteration and only the right hand side is modified. This matrix is inverted only once before the iterations begin.
A Secure Relay Protocol for Door Access Control

Physical keys are easy to use but difficult to manage securely for large institutions. Digital replacements have been created, but dedicated hardware such as smartcards or RFID tags can have the same problems as physical keys. Several commercial products try to solve this by using the users' Bluetooth-enabled mobile devices as keys, but the built-in security of the Bluetooth standard is insufficient. Furthermore, to manage a varying set of users, such systems may require the door locks to be connected to the Internet which may require expensive infrastructure. We present a cryptographic protocol and a prototype implementation that solves these problems by letting door locks communicate with a central server using the Internet connections of the users' mobile devices. The protocol is specified formally in the applied π-calculus and security through secrecy and authenticity is verified using the cryptographic protocol verifier ProVerif. A prototype of the system is implemented for Android smartphones.
dOTM: A Mechanism for Distributing Centralized Multi-party Video Conferencing in the Cloud

One of the key factors for a given application to take advantage of cloud computing is the ability to scale in an efficient, fast and reliable way. In centralized multi-party video conferencing, dynamically scaling a running conversation is a complex problem. In this paper we propose a methodology to divide the Multipoint Control Unit (the video conferencing server) into more simple units, broadcasters. Each broadcaster receives the media from a participant, processes it and forwards it to the rest. These broadcasters can be distributed among a group of CPUs. By using this methodology, video conferencing systems can scale in a more granular way, improving the deployment.
THE MAJOR HISTOCOMPATIBILITY COMPLEX RESTRICTED ANTIGEN RECEPTOR ON T CELLS

A number of recent publications have suggested that the antigen called T4 or Leu-3 in man or L3T4 in mouse is intimately involved in the recognition of antigen (Ag)' in association with Class II products of the major histocompatibility complexes (MHC) of the respective species . Thus T4 monoclonal antibodies block T cell proliferation in response to Class II alloantigens in man, and also block killing mediated by recognition of Class II molecules (1-7) . Similar findings have been obtained in mouse (8, 9) . In these respects the Leu-3, T4 or L3T4 molecule seems to serve a function for Class II-restricted T cells analogous to the function of Leu-2 or T8 molecules in man or Lyt-2 molecules in mouse for Class I-restricted T cells (10-16) . These results have been used by several authors to support theories which propose that these apparently nonvariant molecules act in recognition of antigen by T cells by binding to some nonpolymorphic molecule, or perhaps some nonpolymorphic region of Class I or Class II molecules . By so binding they are presumed to increase the overall avidity of the T cell for its target cell (3, 5, 16, 17) . Thus T cell binding to Ag presenting cells is presumed to be mediated by clone-specific receptors on the T cell for Ag/MHC, and also by the T4, L3T4 or T8, Lyt-2 molecules . Distribution studies, and perhaps common sense, predict that T4, L3T4 would be present on and enhance binding of Class I1-restricted T cells . Other interpretations of the data are possible, however . For example, these nonpolymorphic molecules might serve an anchoring, or signaling, function for
Enforcing Relational Matching Dependencies with Datalog for Entity Resolution

Entity resolution (ER) is about identifying and merging records in a database that represent the same real-world entity. Matching dependencies (MDs) have been introduced and investigated as declarative rules that specify ER policies. An ER process induced by MDs over a dirty instance leads to multiple clean instances, in general. General "answer sets programs" have been proposed to specify the MD-based cleaning task and its results. In this work, we extend MDs to "relational MDs", which capture more application semantics, and identify classes of relational MDs for which the general ASP can be automatically rewritten into a stratified Datalog program, with the single clean instance as its standard model.
2015 Ieee International Conference on Big Data (big Data) Holistic Entity Matching across Knowledge Graphs

—Entity matching is the problem of determining if two entities in a data set refer to the same real-world object. In the last decade a growing number of large-scale knowledge bases have been created online. Tools for automatically aligning these sources would make it possible to unify them in a structured knowledge and to answer complex queries. Here we present Holistic Entity Matching (HolisticEM), an algorithm based on Personalized Page Rank for aligning instances in large knowledge bases. It consists of two steps. First, a graph of potential matching pairs is constructed; second, local and global information from the relationship graph is propagated via Personalized Page Rank. We demonstrate that HolisticEM performs competitively and can efficiently handle databases with 110M and 203M entities accurately resolving 1.6M of matching entity pairs. I. INTRODUCTION A common prerequisite for knowledge discovery is accurately combining data from multiple, heterogeneous sources into a unified, mineable knowledge graph. An important step in creating such a graph is entity matching. Entity matching is the problem of determining if two entities in a data set refer to the same real-world object. It is a complex and ubiquitous problem, that appears in numerous application domains including information extraction, data integration, language processing. As an example consider two toy knowledge graphs in Figure 1ab. Nodes in these graphs are actor, movie, character, performance entities, and their attributes. Edges between nodes correspond to Resource Description Framework (RDF) triples (s, p, o) and are annotated with predicates p. For example, triple (p1, played by, a1) represents an edge between performance p1 and actor a1, meaning that performance p1 was played by an actor a1. A growing body of work has shown that incorporating global information can improve the performance. Some examples are simultaneous coreference in [18], [19], jointly modeled record and field coreference in [6], dirichlet process for modeling interactions between dataset entities in [2], [12], distribution of wrong entries in input datasets for data fusion in [7], probabilistic ontology alignment in [20]. Main limitations of the above techniques are requirements for prior domain knowledge for modeling, data for training, and/or probabilistic inference, which makes these methods computationally infea-sible for large data sets. Missing or incomplete information in the database is another challenge in the entity matching process, e.g. actors a1 and
Examining Reciprocal Relationships between Leader Humility and Team Voice

There is a scarcity of research on antecedents of leader humility and how team members may help leaders to become humble over time. We examine a longitudinal model on reciprocal relationships between leader humility and team voice, and how team voice carries through the effect of humble leaders on team collective turnover intention. We also investigate the moderating role of team procedural justice climate. Using three waves of repeatedly measured data from 411 work teams, we found positive, reciprocal relationships between leader humility and team voice over time (i.e., an upward spiral). The positive effect of leader humility on subsequent team voice is stronger when team procedural justice climate is high. In contrast, the positive effect of team voice on subsequent leader humility is stronger when procedural justice climate is low. Furthermore, team voice mediates the effect of leader humility on subsequent turnover intention of the team as a collective.
Pattern Matching with Variables: Fast Algorithms and New Hardness Results

A pattern (i. e., a string of variables and terminals) maps to a word, if this is obtained by uniformly replacing the variables by terminal words; deciding this is NP-complete. We present efficient algorithms\footnote{The computational model we use is the standard unit-cost RAM with logarithmic word size. Also, all logarithms appearing in our time complexity evaluations are in base 2. } that solve this problem for restricted classes of patterns. Furthermore, we show that it is NP-complete to decide, for a given number k and a word w, whether w can be factorised into k distinct factors; this shows that the injective version (i.e., different variables are replaced by different words) of the above matching problem is NP-complete even for very restricted cases.
Learning Kernels for Semantic Clustering: A Deep Approach

In this thesis proposal we present a novel semantic embedding method, which aims at consistently performing semantic clustering at sentence level. Taking into account special aspects of Vector Space Models (VSMs), we propose to learn reproducing kernels in classification tasks. By this way, capturing spectral features from data is possible. These features make it theoretically plausible to model semantic similarity criteria in Hilbert spaces, i.e. the embedding spaces. We could improve the semantic assessment over embeddings, which are criterion-derived representations from traditional semantic vectors. The learned kernel could be easily transferred to clustering methods, where the Multi-Class Imbalance Problem is considered (e.g. semantic clustering of definitions of terms).
Applying Inspection to Object‐Oriented Code

The benefits of the object‐oriented paradigm are widely cited. At the same time, inspection is deemed to be the most cost‐effective means of detecting defects in software products. Why then, is there no published experience, let alone quantitative data, on the application of inspection to object‐oriented systems? This paper describes the facilities of the object‐oriented paradigm and the issues that these raise when inspecting object‐oriented code. Several problems are caused by the disparity between the static code structure and its dynamic runtime behaviour. The large number of small methods in object‐oriented systems can also cause problems. This is followed by a description of three areas which may help mitigate problems found. Firstly, the use of various programming techniques may assist in making object‐oriented code easier to inspect. Secondly, improved program documentation can help the inspector understand the code under inspection. Finally, tool support can help the inspector analyse the dynamic behaviour of the code. In conclusion, while both the object‐oriented paradigm and inspection provide excellent benefits on their own, combining the two may be a difficult exercise, requiring extensive support if it is to be successful.
Short-term effects of a multi-disciplinary cardiac rehabilitation programme on psychological well-being, exercise capacity and weight in a sample of obese in-patients with coronary heart disease: A practice-level study

Given that many patients referred to cardiac rehabilitation (CR) are obese, diet therapy, exercise training, nutritional and psychological counselling for both obesity and psychological distress should be included as important components in all CR programmes. In this practice-level, observational study we evaluated the short-term within-group effects of a four-week multi-factorial inpatient CR programme specifically addressed to weight loss, fitness improvement and psychological health increase on 176 obese in-patients with coronary heart disease (CHD). Outcome measures were exercise capacity measured with estimated metabolic equivalents (METs), body mass index (BMI) and psychological well-being (PGWBI). Results show statistically significant improvements in all the PGWBI sub-scales and total score, except in general health (p = 0.393). No moderation effects were found for BMI class, age, diabetes and ejection fraction (EF). METs significantly increased by 30.3% (p < 0.001) and BMI decreased by 1.37 points (p < 0.001). Significant correlations were found between BMI and weight reductions with PGWBI anxiety and total score improvements. This multi-disciplinary CR programme including diet therapy, exercise training and psychological counselling provides indication for short-term within-group effectiveness on functional exercise capacity, BMI and PGWBI in a sample of obese in-patients with CHD. However, controlled studies are needed to corroborate the results we found.
Improving the Use of Evidence-Based Instructional Practices for Paraprofessionals

Coaching has been shown to improve the use of evidence-based instructional practices (EBIPs), but relatively few studies have been conducted to assess the effectiveness of coaching for adults belonging to minority groups and paraprofessionals in public elementary school settings. In this study, a multiple probe design across participants was used to assess the effectiveness of coaching and the provision of feedback on the use of prompting procedures and associated practices for three adults supporting three young students with autism in a self-contained elementary school setting. Results showed improved use of target practices and increased student engagement. More research is needed regarding the training and coaching of teaching teams and the use of evidence-based coaching and feedback practices to assist paraprofessionals in implementing EBIPs with small groups of students and in a variety of educational settings.
Influence of solder microstructure and oxide layers on high frequency electrical losses of WL-CSP Pb-free interconnections

In this paper, results of study of the effects of microstructures and thick surface oxide layers of near eutectic Sn3.8Ag0. 7Cu solder alloy on high-frequency losses from 500 MHz to 50 GHz are presented. To analyze the high frequency losses in the solder alloy, a new test method was employed. The test modules consisted of lead-free microstrip lines (SnAgCu) mounted on a low-loss liquid crystal (LCP) polymer substrate. The experimental results showed that the colony size or the high dispersion of the Ag3Sn and Cu6Sn5 intermetallics do not have a significant influence on the high frequency losses. On the contrary, the conductor loss increased when thick oxide layer was present on the surface of the solder alloy. A design rule for insertion loss estimation for hot components was also determined. By making use of the theoretical and experimental results on the annealed SnAgCu specimen the correction coefficient value of 1.4 for the conductor loss was obtained. The increase of conductor loss of the WL-CSP interconnections, having a pitch of 500 mum and bump diameters of 300 mum, was calculated to be about 40% higher for differential and single-ended signaling when the thick oxide layers are present
High Order Spatial Audio Capture and Its Binaural Head-Tracked Playback Over Headphones with HRTF Cues

A theory and a system for capturing an audio scene and then rendering it remotely are developed and presented. The sound capture is performed with a spherical microphone array. The sound field at the location of the array is deduced from the captured sound and is represented using either spherical wave-functions or plane-wave expansions. The sound field representation is then transmitted to a remote location for immediate rendering or stored for later use. The sound renderer, coupled with the head tracker, reconstructs the acoustic field using individualized head-related transfer functions to preserve the perceptual spatial structure of the audio scene. Rigorous error bounds and Nyquist-like sampling criterion for the representation of the sound field are presented and verified.
Utilization of Spinal Manipulation in a Case of Adolescent Idiopathic Scoliosis (AIS)

This study describes the utilization of spinal manipulation in a case of Adolescent Idiopathic Scoliosis (AIS). A 15- year-old female presented to the clinic with musculoskeletal back pain, and cosmetic concerns regarding progression of her scoliosis. After clinical exam and radiographic studies, an angle of 18° of Idiopathic Dextroconvex Scoliosis of the thoracolumbar spine was recognized, with obvious muscle asymmetry and body deconditioning. Spinal manipulation was utilized as primary interventional procedure for a 6-month period of treatment. Adjunctive therapies for body conditioning, such as therapeutic exercises, and nutritional counselling was suggested. By the end of the treatment plan, the magnitude of the scoliotic curve was reduced by 7°, remaining virtually unnoticeable, and asymptomatic.
FlexForward: Enabling an SDN manageable forwarding engine in Open vSwitch

This paper presents FlexForward, an approach for dynamically manage SDN data plane forwarding mechanisms. This feature leverages SDN flexibility in two aspects: (i) it provides a new management method, in which topological infrastructure requirements are satisfied by the most appropriate forwarding mechanism, residing in each managed network element; (ii) further decoupling between control and data planes in SDN by offering tableless forwarding support. As proof of concept, an implementation with different forwarding methods is carried out in Open vSwitch. Results show that FlexForward is able to achieve seamless switchover between forwarding methods. It also allows efficient tableless forwarding implementations, improving by up to 31% in latency, and 90% in throughput, when compared to regular OpenFlow.
A Conceptual Model for Bidirectional Service, Information and Product Quality in an IS Outsourcing Collaboration Environment

This paper advances theory on the process of collaboration between entities and its implications on the quality of services, information, and/or products (SIPs) that the collaborating entities provide to each other. It investigates the scenario of outsourced IS projects (such as custom software development) where the extent of collaboration between a client and vendor is high. Using the social exchange theory, the proposed conceptual model tries to establish the "bidirectional" nature of SIP quality in a collaborative environment, where the SIPs exchanged are possibly "dependent" on each other, and if any entity wishes to receive high SIP quality then it should make efforts to provide high SIP quality in return too. Furthermore, it advocates increasing efforts to link financial stakes (tangible or intangible monetary benefits or risks) to the quality of SIP being continuously exchanged throughout the project lifecycle.
Introduction to Lessons from the Financial Turmoil of 2007 and 2008

Global fi nancial markets have now been in turmoil for over a year. The crisis began to unfold around the time of last year’s Conference, with adverse news about the US sub-prime mortgage market gaining prominence in June and July 2007. By August, problems in credit markets had become widespread and spreads in interbank markets had increased signifi cantly. While it was recognised towards the end of last year that these events may still have a while to play out, it was thought that it would be useful to make an early assessment of the nature of the crisis, consider its possible causes and discuss the merits of various policy responses.
A Hazard-Free Delay-Insensitive 4-phase On-Chip Link Using MVCM Signaling

In this paper, we introduce a 3valued MVCM 4- phase link, where cores at each end of the link use 4-phase dual-rail protocol. The dual-rail N-bit data are encoded onto N+1 wires on the link, thus reducing the number of interconnects between cores and improving power and crosstalk features. We show that it is impractical to encode a 2- phase dual-rail asynchronous data bit onto one wire using MVCM signaling, which was used in previous works, as it generates an unavoidable hazard at the receiver end. The main advantage of our design is that it does not generate any hazards. To evaluate our claim, we use a simple transmitter and receiver implemented in 130 nm technology. Results show a hazard-free communication over different link lengths in contrast to previous works.
