Carrier Interference Compensation using PSO algorithm.

The Single Carrier Frequency Division Multiple Access (SC-FDMA) faces a major drawback of Inter Carrier interference (ICI) due to frequency offset mismatch between the transmitter and the receiver. This results in the disruption of the orthogonality in the system. In this paper, an uplink MIMO SC-FDMA is designed with the perfect knowledge of the Cyclic Frequency Offsets (CFO). Particle Swarm Optimization (PSO) algorithm which is a population-based meta heuristic algorithm is used to mitigate the effect of ICI without the assumption of CFO. The system provides better performance when compared to the other existing systems from the results obtained through simulation.
Which Evaluations Uncover Sense Representations that Actually Make Sense?

Text representations are critical for modern natural language processing. One form of text representation, sense-specific embeddings, reflect a word’s sense in a sentence better than single-prototype word embeddings tied to each type. However, existing sense representations are not uniformly better: although they work well for computer-centric evaluations, they fail for human-centric tasks like inspecting a language’s sense inventory. To expose this discrepancy, we propose a new coherence evaluation for sense embeddings. We also describe a minimal model (Gumbel Attention for Sense Induction) optimized for discovering interpretable sense representations that are more coherent than existing sense embeddings.
Optimal memory utilization and wire length minimization for reducing energy consumption of VLSI circuits

—the main component of computation model are energy, space, and time. Minimizing them is challenging in building efficient processing design. This work overcomes the problem of using caching utilizing reversible logic circuits (RLC). Further, high communication overhead among cache and main memory affects performance and incurs high heat in VLSI component such as GPU, CPU etc. Thus, limiting or efficient usage of memory resource is most desired. For using RLC, it is important to reduce the delay and wire length of VLSI circuit. This work present an Information processing unit (IPU) using logically reversible circuit using adiabatic reversible Toffoli gate. For minimizing path delay due to presence of faults in circuit design Elmore model is used both at switch level and at wire level and linear model is used at the gates. Further, for bringing tradeoff between memory minimization and delay (processing time) requirement a delay aware rectilinear Steiner minimum tree (RSMT) is created. Experiment are conducted on industrial circuits in the ISPD98 benchmark data. The outcome attained show the proposed model reduces wire length, processing time and memory usage when compared with existing model. Thus, our model aid in improving thread-level and instruction-level parallelization under shared memory environment such as GPU.
Transfer learning for question answering on SQuAD

This paper focuses on the beneﬁts of transfer learning on question answering tasks. We show how transfer learning improves the results of state of the art question answering system on evaluation set focused on a speciﬁc domain not contained in the training data. We perform several experiments on the Stanford Question Answering Dataset (SQuAD). We use transfer learning approach to retrain model trained with a large amount of generic data on smaller topic speciﬁc datasets. We evaluate the change in performance of the system with regards to the size of the new training set and type of data used in training.

Analysis of Active and Passive Mechanism for Image Forgery Detection

—With the expanding accessibility of carefully put away data and the advancement of new multimedia services, security questions are ending up considerably more critical This paper shows a procedure ready to check digital image (DI) with an invisible and undetectable emit data, called the watermark. This procedure can be the premise of a total copyright security system. The procedure initial step comprises in delivering a discharge picture. The initial segment of the mystery dwells in essential data that structures a parallel picture. That picture is then recurrence adjusted. The second piece of the mystery is decisively the frequencies of the bearers. The two insider facts rely upon the character of the copyright proprietor and on the first picture substance. They got picture is known as the stamp. The second step comprises in balancing the adequacy of the stamp as per a concealing basis originating from a model of human observation. That excessively hypothetical basis is adjusted by methods for morphological apparatuses situating in the photo the spots where the measure is assumed not to coordinate. This is trailed by the adjustment of the level of the stamp at those spots. The so shaped watermark is then added to the first to guarantee its security. That watermarking strategy permits the identification of watermarked pictures in a surge of DI, just with the information of the photo proprietor's insider facts.
Prevalence of Different Mould Genera in Meat and Meat Products with Some Reduction Trials using Essential Oils

| This study aimed to observe the hygienic status of raw meat, fresh minced meat, luncheon, beef burger and sausage (40 each) retailed in Zagazig city, Sharkia Governorate, Egypt. Total mould count, prevalence of mould species as well as the ability of the most fungal isolates to produce lipase and protease enzymes had been conducted. The antifungal potential of clove, thyme, garlic (0.5%, 1%) essential oils and potassium sorbate 0.3% had been evaluated. The highest mean (log10 cfu/g) total mould count (2.85 ± 0.12) was recorded in sausage. The most prevalent species recovered from the examined meat and meat product samples were Aspergillus, Penicillium and Cladosporium while Alternaria, Fusarium, Mucor, Rhizopus, Sporotricum, Thamnidium and Curvularia species were recovered at low percentages. A. niger was the most predominant Aspergillus spp isolated from sausage, luncheon, raw meat, fresh minced meat and beef burger with prevalences of 50%, 45.5%, 44.4%, 41.4% and 33.3% respectively. Among 262 tested isolates, 216 (82.4%) could produce protease, 233 (88.9%) produce lipase. Essential oils caused significant inhibition on fungal growth. Clove (Syzygium Aromaticum) oils 1% and thyme (Thymus Vulgaris) oils 1% were found to be more effective than the others, although Clove 1% gave the best result in inhibition of A. flavus growth, but the odour of thyme is more palatable than that of clove. In conclusion, the obtained results revealed inadequate hygienic measures during transportation, processing, storage and distribution of meat and meat products. Therfore, strict hygienic practices should be followed. Moreover, clove, thyme and garlic (Allium Sativum) have the potential to be used as flavoring and natural preservatives in food. AminA H.A.

Human Osteogenic Adipose-Derived Progenitor Cells as a Source of Vascular Endothelial Growth Factor

Cell-based therapies have shown particular promise in several difficult-to-treat conditions and diseases [5-7]. Human adipose-derived stem cells (ASCs) hold unique qualities for use in regenerative medicine. A well-known benefit of ASCs lies in their unique ability to differentiate along with several mesodermal and endothelial lineages as human adipose-derived progenitor cells (APCs) [8,9]. APCs may directly repair, replace, or regenerate multiple cell types in the cardiac myocardium [10-13]. In addition to the regenerative benefit of multi-differentiation, ASCs also secrete several cytokines that promote angiogenesis. One of the most well studied angiogenic cytokine is vascular endothelial growth factor (VEGF) [8,9,14,15]. VEGF is involved in several angiogenic functions, to include endothelial cell migration, mitogenesis, vascular sprouting, and vascular tube formation [16,17]. VEGF-A is the most active multi-tasking factor among the VEGF family of proangiogenic cytokines and is essential for cardiovascular development and function [18,19].
Knowledge Valuation Management System – Design of a Holistic System for Strategic Knowledge Planning

Knowledge can be identified as one of the fundamental elements of business success. The real challenge of the “Knowledge Age” is the effective handling of this resource within the management cycle. This cycle can be described through planning, realisation, and control. Planning reflects the strategic aspect, the actual realisation is the operative component and control represents the verification of both. The strategic part is especially underdeveloped today. Strategic knowledge planning forms the basis for all further activities. It allows us to verify the attainment of knowledge goals and gives advice for handling the identified results. The aim of this process is a strategic plan with milestones for the operative part of the knowledge management cycle. In our opinion, support is necessary using an information technology system for the elements of the described cycle. A large number of tools can be found for the operative aspect of knowledge planning. Information systems for the strategic part are seldom and mostly just for presentation without any kind of integration into an existing corporate system landscape. One solution to this problem is the “Knowledge Valuation Management” (KVM) Architecture. The architecture supports the process of knowledge planning through the valuation of knowledge. The aim is to verify the attainment of knowledge goals. The architecture is subdivided into four layers (presentation, business, integration, and data) and five modules (interface description, knowledge measurement, knowledge basis, knowledge valuation, and knowledge analysis). With the help of this architecture the mostly unstructured knowledge planning process now has a tool for the continuous verification of the achievement of knowledge goals in order to better handle knowledge as a valuable resource. Our paper describes the support of the complex process of knowledge planning through an information system. This holistic approach based on the achievement of knowledge goals and integrates all supporting activities (methodical as well as technical). The proposed architecture represents a new way for the corporate management to handle this process in a better manner.
Sticking with Landlines? Citizens' Use and Perception of Social Media in Emergencies and Expectations Towards Emergency Services in Germany

Crisis informatics has examined the use, potentials and weaknesses of social media in emergencies across different events (e.g., man-made, natural or hybrid), countries and heterogeneous participants (e.g., citizens or emergency services) for almost two decades. While most research analyzes specific cases, few studies have focused on citizens’ perceptions of different social media platforms in emergencies using a representative sample. Basing our questionnaire on a workshop with police officers, we present the results of a representative study on citizens’ perception of social media in emergencies that we conducted in Germany. Our study suggests that when it comes to emergencies, socio-demographic differences are largely insignificant and no clear preferences for emergency services’ social media strategies exist. Due to the widespread searching behavior on some platforms, emergency services can reach a wide audience by turning to certain channels but should account for groups with distinct preferences.
Woman’s Attitude as a Victim of Violence: Extending or Narrowing the Gender Gap

This paper discusses the findings of a European Project DAPHNE III in the Cyprus context. Its twofold aim regards: a) the uncovering of the woman‟s attitude as a victim of violence in relation with her feelings and her conscience on the indirect impact of violence against her upon her children if exposed and b) the extracting of an elaborate understanding on the way gender gap is either extended or narrowed by the woman‟s attitude. What the research points out is that: a) violence against women mostly results in survivor behavior focused only on ensuring survival and not on leaving from the abusive relationship and b) the predetermined gendered roles for men and women contribute to the dynamic of violence against women and to the formation of their attitude as victims. The main methodology performed is based on the Project‟s initial phases: a) Data collection from women‟s written testimonies and b) Data Collection from semi-structured interviews with women; both cases concern women who have suffered violence and are mothers. So, 28 women‟s written testimonies and 17 transcribed interviews with women have been analyzed using content, thematic and discourse analysis techniques. Results indicate that the woman‟s attitude as a victim of violence is mainly determined by the discourses of powerlessness, of tolerance, of denying, of blaming self and of compassion. Findings are discussed in the light of Domestic Violence and Gender Studies debate and frameworks.
Bounding the Joint Distribution of Disability and Employment with Contaminated Data

Understanding the relationship between disability and employment is critical and has long been the subject of study. However, estimating this relationship is difficult, particularly with survey data, since both disability and employment status are known to be misreported. Here, we use a partial identification approach to bound the joint distribution of disability and employment status in the presence of contaminated data. Allowing for a modest amount of contamination leads to bounds on the labor market status of the disabled that are not overly informative given the relative size of the disabled population. Thus, absent further assumptions, even a modest amount of contamination creates much uncertainty about the employment gap between the non-disabled and disabled. However, additional assumptions considered are shown to have some identifying power. For example, under our most stringent assumptions, we find that the employment gap is at least 15.2% before the Great Recession and 22.0% afterwards.
Representing Objects in Video as Space-Time Volumes by Combining Top-Down and Bottom-Up Processes

As top-down based approaches of object recognition from video are getting more powerful, a structured way to combine them with bottom-up grouping processes becomes feasible. When done right, the resulting representation is able to describe objects and their decomposition into parts at appropriate spatio-temporal scales. We propose a method that uses a modern object detector to focus on salient structures in video, and a dense optical flow estimator to supplement feature extraction. From these structures we extract space-time volumes of interest (STVIs) by smoothing in spatio-temporal Gaussian Scale Space that guides bottom-up grouping. The resulting novel representation enables us to analyze and visualize the decomposition of an object into meaningful parts while preserving temporal object continuity. Our experimental validation is twofold. First, we achieve competitive results on a common video object segmentation benchmark. Second, we extend this benchmark with high quality object part annotations, DAVIS Parts 1, on which we establish a strong baseline by showing that our method yields spatio-temporally meaningful object parts. Our new representation will support applications that require high-level space-time reasoning at the parts level.
ON HIGHER RANK INSTANTONS & THE MONOPOLE COBORDISM PROGRAM

Witten’s conjecture suggests that the polynomial invariants of Donaldson are expressible in terms of the Seiberg-Witten invariants if the underlying four-manifold is of simple type. A higher rank version of the Donaldson invariants was introduced by Kronheimer. Before even having been defined, the physicists Mariño and Moore had already suggested that there should be a generalisation of Witten’s conjecture to this type of invariants. We study a generalisation of the classical cobordism program to the higher rank situation and obtain vanishing results which gives evidence that the generalisation of Witten’s conjecture should hold.
CASTLES’ TRADE-OFF REVISITED: INDIVIDUAL AND INSTITUTIONAL DETERMINANTS OF OLD-AGE POVERTY

In this paper, we use ECHP-data in order to provide a more elaborate empirical test of the so-called trade-off hypothesis suggested by Kemeny (1981) and Castles (1998), which implicates the existence of a possible trade-off between the extent of home-ownership and the generosity of old-age pensions. To this end, we evaluate the impact of a range of institutional arrangements referring to both pension and housing policies on the old-age poverty risk, the most important addition to previous research being the inclusion of social housing provision as an important alternative to the encouragement of home-ownership. Although we find substantial empirical evidence in favour of the trade-off hypothesis, our results point at several avenues for further discussion and research. Firstly, we find that neither generous pensions nor high ownership rates have the strongest poverty-reducing potential, as this role is mainly fulfilled by social housing policies for the elderly. Furthermore, our results point at the existence of a group of elderly who are faced with a double disadvantage, in the sense that in high-ownership countries, the elderly who do not possess their own homes also tend to receive smaller pension benefits. Although this effect at least partly arises as a result of selection – the larger the ownership sector, the more selective the group of people who do not own their homes –, the concomitant higher poverty risk for the group of ‘non-owners’ does not seem to be countered by the pension system.
Three-Phase Four-Wire Distribution System Utilizing Unified Power Quality Conditioner

Retrieval Number: B1726074214/2014©BEIESP 83 Published By: Blue Eyes Intelligence Engineering & Sciences Publication Abstract— This paper presents a novel structure for a threephase four-wire (3P4W) distribution system utilizing unified power quality conditioner (UPQC). The 3P4W system is realized from a three-phase three-wire system where the neutral of series transformer used in series part UPQC is considered as the fourth wire for the 3P4W system. A new control strategy to balance the unbalanced load currents is also presented in this paper. The neutral current that may flow toward transformer neutral point is compensated by using a four-leg voltage source inverter topology for shunt part. Thus, the series transformer neutral will be at virtual zero potential during all operating conditions. The simulation results based on MATLAB/Simulink are presented to show the effectiveness of the proposed UPQC-based 3P4W distribution system.
MPPT OF PV SYSTEMS UNDER PARTIAL SHADED CONDITIONS BY USING DIFFERENTIAL EVOLUTION AND PSO

With the increasing demand of energy, renewable energy sources such as wind, solar are getting more attention as compared to conventional energy sources because of fuel cost, global warming, depletion of fossil fuels and lesser noise. Among different renewable energy sources, the photovoltaic generation is the most attractive research during the past decades. The major issue involved in solar PV system is low conversion efficiency; further the efficiency reduces under partial shaded conditions (PSC). Thus there is need of control algorithms which can extract the maximum power from this system irrespective of the environmental conditions such as temperature and irradiations. Numerous control algorithms have been proposed in recent years like PSO, Firefly and Differential evaluation. The performance of PSO and DE algorithms in terms of tracking speed, initial oscillations and tracking efficiency is validated through simulation studies and hardware implementation.
