Case Report: Dermoscopic features of oral lichen planus - the evolution of mucoscopy
Authors: Sonthalia Sidharth , Varma Sangeeta , Jha Abhijeet Kumar , Jakhar Deepak , Kaliyadan Feroze
Published: March 2018

Dermoscopy, a non-invasive technique for cutaneous diagnosis is being increasingly studied in various disorders of the skin, nails and scalp. However, it has been under-utilized for the diagnosis and characterization of mucosal disorders. The dermoscopic characterization of cutaneous lichen planus and its variants has been well documented with Wickham’s striae constituting the hallmark of the condition. However, the dermoscopic features of oral lichen planus with hand-held or videodermoscopy remain to be elucidated. We present the case of a young adult man who presented with asymptomatic white lacy lesions over a bluish-black background over the tongue, patchy hyperpigmentation of the buccal mucosae and gingivae, and longitudinal melanonychia involving some nails. History of intake of any drugs preceding the lesions, smoking, chewing of betel nut and dental implants was negative. Family history was non-contributory. There were no cutaneous lesions suggestive of lichen planus. Mucoscopy (dermoscopy of the mucosa, oral in this case) and onychoscopy were done followed by biopsy from the tongue that confirmed the diagnosis of lichen planus. Oral mucoscopy of the tongue revealed a tri-colored pattern with structureless veil-like grey-white areas (modified Wickham’s striae), well-demarcated red glossy erosions, and violaceous-to-brown clods. Additionally, vascular pattern of dotted and linear to curved vessels along the borders of leukoplakia-like areas and erosions were observed. Onychoscopy confirmed lichen planus-associated melanonychia. Dermoscopy also proved useful in conveniently ruling out other disorders typified by mucosal and nail pigmentation such as Laugier Hunziker syndrome and drug-induced changes. Although direct oral microscopy has been used in defining features of oral lichen planus, to the best of our knowledge this case is the first report on mucoscopy or dermoscopy of oral lichen planus

In this article – based on selected examples and with no certainty that they have been aptly chosen – I would like to point out and make a preliminary analysis of certain positions in Polish public discourse which currently display striking elements of transference in the sense of Dominick LaCapra’s meaning of the term. They reverberate with reflections of Polish imagined community’s experiences from the Occupation period. In this description, I shall rely on the classic categorisation introduced by Raul Hilberg, successively discussing the identification of subjects with the positions of perpetrator, victim and witness.
Zwój Estery a Szoa
Authors: Plichta Paweł
Published: March 2018

The article contains an analysis of the construction of the narrative of the Shoah, using motifs from the Book of Esther. Non‑fiction book: Code of Esther, 2013 (Le Code d’Esther, 2012), written by French journalists: Bernard Benyamin and Yohan Perez is a record of investigative journalism. During the investigation various interpretations of the “enigmatic” words of Julius Streicher – a Nazi war criminal in the context of the biblical text are recalled. The title of the book and its cover’s design predicts sensation while the attractiveness of the communication is achieved by using of multimedia elements (online videos illustrating the described events, accessible through QR codes placed in the book), and an invitation to interact through thematic websites, social networking sites like Facebook and Twitter. The authors, belonging to the “second generation”, derive knowledge and experiences through mediation, which is the reason of the treatment of the book in terms of post‑memory.
Tanatoturystyka: doświadczenie, pamięć, etyka

Published: March 2018

The aim of this paper is to introduce dilemmas and challenges connected with presenting the past and history to thanatourists. For this purpose, we will explain the main features of dark tourism, which deals with the so called difficult/dissonant heritage. This characteristic will help to pay attention to the difficulties with exhibiting dark objects, which, in the course of time, become more and more commercialized. The last problem, raised in this article, is confrontation between tour guides’ narration about history and its perception among tourists representing different cultures. Information derived from non‑directive interview with Cracow tour guides will serve as examples for theoretical reflection.
"Jeśli my zapomnimy, kto będzie pamiętał?"
Authors: Kabrońska Joanna
Published: March 2018

The text is an attempt to determine the relationship between post‑memory (or – in other words – “vicarious memory”) and art. Particular attention is given to visual arts. The works of artists of the younger generation, such as Libera, Bałka, Żmijewski, and to some extent Betlejewski, who explored the memory of the Shoah, were discussed. Their works can be considered a form of manifestation of post‑memory. Assuming that the analysis of artistic phenomena is not possible without reference to the social context in which art is created and its social responsibility, the works of these artists were confronted with the material traces of memory (including Jedwabne, Kolno, Jeleniewo) that shape the social background of artistic creativity, its reception and debate about it.
Kto ma pamięć podziurawioną?
Authors: Ciarkowska Anna
Published: March 2018

Henri Raczymow’s term of mémoire trouée – memory with holes – is often understood as a synonym to Marian Hirsch’s “postmemory”. Even though there is a semantic connection between these two concepts, it seems important to point out differences between them. Mémoire trouée concept was presented by Raczymow in 1986 on the Jewish Writers Conference. The essay became a collective voice of Jewish immigrants in France. What is this “hole” in the memory? How did it appear? What are literary methods of description of this void? Most of all, this void has its “double” – emptiness in the “shtetl memory” and emptiness in the “Shoah memory”. The aim of this article is to analyze Raczymow’s essay, especially his conception of “the second generation’s” writing; to interpret voids in the memory in the Jewish experience and literary transposition of mémoire trouée in Raczymow novels.
Pamięć wielkiej wojny ojczyźnianej w narracjach młodzieży

Published: March 2018

The present paper confronts the dual nature of the Great Patriotic War narrative − the official (collective) and the personal − young people’s memory of that war. The author, by pointing out the discrepancies between the official myth and individuals experience − as reconstructed by students based on their relatives’ narratives (grandmothers’ or grandfathers’) − emphasizes the importance of a personalized war experience pieced together by young people. She draws the reader’s attention to the de‑ideologization and the de‑composition of the ruling myth by young people. She discusses their attempts to make the official narrative more authentic − through the eyes of individual witnesses. She also emphasizes the students’ efforts to recover the memory of The Great Patriotic War exposing the elements outside the realm of mainstream remembrance propaganda. She stresses the fact that it is necessary for young people to endure the trauma of personal narratives.

Published: March 2018

The national parliament is crucial institution in a contemporary European states, which guarantees a legitimacy of a power and regime. At the same time, the effectiveness of a parliament is one of the most important hallmark of a democratic political system. The democratic legitimacy, which comes from a national parliament is one of the sphere of the national system of implementing European policy. The author, using the system approach in European studies research, analyze the evolution of the role and functions of the Polish Sejm and Senate in the pre‑accession period, i.e. before the year 2004. The role of Polish parliament is analyzed through the two research perspectives – historical and functional. In this way it is clearly observed a growing role of the Sejm and Senate in the relations with other political institutions within a national system of implementing European policy.

International relations science research space In this article the research problem is connected to relations between the change of international reality on the one hand, and the science of international relations, its theory, methodology and the terminology, on the other. International relations under conditions of globalization processes are subject to a radical, qualitative change encapsulated in the formula of the late‑Westphalia order. Meanwhile theories of international relations, methodology of examining them came into existence in qualitatively other reality called the Westphalia system of international relations. Essential question is whether theories as well as research methods, but also a terminology which rose in conditions and for the purposes of explaining the Westphalia reality, are able to analyse and to explain late‑Westphalia reality? There is an analysis of the influence of the change of international reality, i.e. the subject of the research on applied theories, methodology and the terminology. In the methodological meaning the change of international relations is treated as an independent variable, and the change of the theory, methodology and the terminology is a dependent variable. The hypothesis is subjected to the verification, according to which a pluralism and hybrydity of the late‑Westphalia order is accompanied by a pluralism and an eclecticism of theories and research methods within the science of international relations. For the need of analysis of the taken research problem – what is also finding expression in the title of article – it has been acknowledged that talking about the research space is more justified, than about border disciplines. It has been acknowledged that the research space of international relations as the discipline has multi‑layered structure composed of the subject of the research, theories, methodological assumptions and methods, and language of discipline. These four elements determine the structure of the identity of the international relations as the discipline. The analysis has been focused on changing ontology of international relations and its impact on epistemology, methodology and terminology.
Dlaczego pytanie o granice politologii jest ważne?
Authors: Ulicka Grażyna
Published: March 2018

Why is the question about limits of political science important?

The text discusses the following issues: how limits of political science are defined, how their comprehension determines the strategies adopted by individual researchers and collective bodies representing the discipline, at what stages of the discipline development and at what critical moments in its development the question about the limits becomes particularly important. What determines the topicality of the question about the limits of the discipline is issues such as: the necessity to fully engage in international cooperation, in particular the European one; the need to establish proper relations with the political science sub‑disciplines which make attempts at becoming independent; the necessity to combine the discipline development with labour market needs. According to the Author, this requires that Polish political science should cross the limits of those areas which have not fallen into the domain of its broader interests to date: especially empirical and comparative research on political systems, economics of politics (political economics), historical sociology of politics.
Normatywne i empiryczne teorie demokracji
Authors: Antoszewski Andrzej
Published: March 2018

Normative and empirical theories of democracy The phenomenon of democracy may be considered either as some desired political project or some kind of political reality. This paper focuses on normative and empirical theories of democracy. They are both essential in the research of it. The main task of normative theories is to deliver the vision of political system based on such values as liberty, equality and dignity of individuals, protecting civil and political freedoms, and making the government accountable to the citizens. Empirical theories describe and explain the mechanisms of such a systems. Without normative theories we lack the knowledge about how should democracy function. Without empirical theories we do not know how and why does it really work. What we really need in order to understand democracy is the uniting of both approaches.

Research problem
A problem is a question which concerns some lack of knowledge. A number of research problems types may be distinguished. The questions about facts are fundamental. However, they are particularly significant in natural sciences. In social sciences (e.g., what is the structure of the ruling elite in prerogative states?) their significance is considerably smaller. Then, there is the type of classificatory questions, i.e., these questions relate to the distinctive features of the class of beings, phenomena of facts fulfilment by being, phenomenon or fact. Indeed, the questions about relations between dependent and independent variables are the most prevalent in social sciences. The last type of questions is formulated on the basis of the model of antinomic behavioural ideal types. This type is characterized by the high extent of applicability to research (i.a., qualitative analyses). It is useful because offers frameworks to determining distances between being/phenomenon/fact and its behavioural ideal type.

Nauki o polityce i ich usytuowanie w systemie nauk
Authors: Janusz Grzegorz
Published: March 2018

As the political science has been assigned to new field and domain of social science in 2011 instead of being assigned to humanities, it has caused astonishment and some kind of discomfort in many centres of political science. It was similar to introducing of a new field called public policy science. Assessment of the environment was quiet diverse. As far as by the public policy science one can notice lack of interest, by the new assignment of policy science one can distinguish three contentions: inclusion of the political sciences in the domain of social science, renewed assignment of policy sciences to humanities and assignment of the political sciences to both domains (management studies alike). The third solution is the most supported one in the environment of political scientists. On the same time statements of politicians about reportedly demanded education of welders instead of political scientists and diminished interest with political studies have made the environment of policy analysis anxious. It is to be emphasised that we are not newly formed field of science and any discussions about status of our domain are an ancient history. At the present day staff of the centres of political sciences is outweighed by people, who graduated political studies and their scientific development together with their tittles of professor have been connected with investigations on the field of political studies. This way the environment grows stronger. A few dangers to political science can be pointed out. First of all there is an aspiration to autonomy of some subfields. Second, there is lack of scientific discussion in the environment. Third, there is a western technique of mechanical “scaling”, “measuring” and other ways of evaluation of one’s academic background, which does not fit to Polish reality and also pervert valuable academic backgrounds.

Behavior-Based Pricing in Marketing Channels
Authors: Li Krista J.
Published: March 2018

With behavior-based pricing (BBP), firms use customers’ purchase history data to price discriminate between past and new customers. Prior research has examined BBP in a non-channel setting. In this paper, we investigate BBP in a channel setting in which manufacturers sell to customers through exclusive retailers. We examine how channel members’ adoption of BBP affects wholesale and retail prices, profits, consumer surplus, and social welfare. We find that BBP decreases channel members’ profits when retailers use BBP and manufacturers use uniform pricing. However, BBP increases channel members’ profits when manufacturers and retailers use BBP. In addition, BBP by retailers alone increases consumer surplus, whereas BBP by manufacturers and retailers decreases consumer surplus. When manufacturers also use BBP, BBP decreases social welfare to a greater degree than when only retailers use BBP. Furthermore, when manufacturers cannot use BBP, their profits are higher with long-term wholesale price contracts. When manufacturers can use BBP, short-term wholesale price contracts yield higher profits for manufacturers and retailers.

An Analysis of Price vs. Revenue Protection: Government Subsidies in the Agriculture Industry
Authors: Alizamir Saed , Iravani Foad , Mamani Hamed
Published: March 2018

The agriculture industry plays a critical role in the U.S. economy, and various industry sectors depend on the output of farms. To protect and raise farmers’ income, the U.S. government offers two subsidy programs to farmers: the Price Loss Coverage (PLC) program, which pays farmers a subsidy when the market price falls below a reference price, and the Agriculture Risk Coverage (ARC) program, which is triggered when farmers’ revenue is below a threshold. Given the unique features of PLC and ARC, we develop models to analyze their impacts on consumers, farmers, and the government. Our analysis generates several insights. First, while PLC always motivates farmers to plant more acres compared to the no-subsidy case, farmers may plant fewer acres under ARC, leading to a lower crop supply. Second, despite the prevailing intuition that ARC generally dominates PLC, we show that both farmers and consumers may be better off under PLC for a large range of parameter values, even when the reference price represents the historical average market price. Third, the subsidy that increases consumer surplus results in higher government expenditure. Finally, we calibrate our model with U.S. Department of Agriculture (USDA) data and provide insights about the effects of crop and market characteristics on the relative performance of PLC and ARC. We provide guidelines to farmers for enrolling crops in the subsidy programs, and show that our guidelines are supported by farmers’ enrollment statistics. We also show that if the economic and political frictions caused by running the subsidy programs is significant, the subsidy that benefits both consumers and farmers may actually result in lower social welfare.

Joint Dynamic Pricing and Order Fulfillment for E-commerce Retailers
Authors: Lei Yanzhe (Murray) , Jasin Stefanus , Sinha Amitabh
Published: March 2018

We consider an e-commerce retailer (e-tailer) who sells a catalog of products to customers from different regions during a finite selling season and fulfills orders through multiple fulfillment centers. The e-tailer faces a joint pricing and fulfillment (JPF) optimization problem: at the beginning of each period, the e-tailer needs to jointly decide the price for each product and how to fulfill an incoming order (i.e., from which warehouse to ship the order). The objective of the e-tailer is to maximize its total expected profits defined as total expected revenues minus total expected shipping costs. (All other costs are fixed in this problem.) The exact optimal policy for JPF is difficult to solve; so, we propose two heuristic controls that have provably good performance compared to reasonable benchmarks. Our first heuristic control directly uses the solution of a deterministic approximation of JPF as its control parameters. Our second heuristic control improves the first one by adaptively adjusting the original control parameters according to the realized demand. An important feature of the second heuristic control is that it decouples the real-time pricing and fulfillment decisions, making it easy to implement. We show theoretically and numerically that the second heuristic control significantly outperforms the first heuristic control and is very close to a benchmark that jointly reoptimizes the full deterministic problem at the beginning of every period.

Effects of Assortment Breadth Announcements on Manufacturer Competition
Authors: Heese H. Sebastian , Martínez-de-Albéniz Victor
Published: March 2018

Retailers typically use assortment planning to maximize store profits given product characteristics. We study the manufacturers’ price-setting interactions and how these can be manipulated by the retailer’s assortment strategy. We show that constraining the breadth of the assortment has two main effects on retailer profits: First, a larger assortment may intensify competitive pressure and decrease prices because manufacturers need to fight harder for market share. Second, a smaller assortment may also reduce manufacturer prices because manufacturers want to ensure that they are included in the chosen assortment, which may lead to higher profits despite lower variety and possibly lower revenues. We optimize retailer assortment strategies, taking into account these two effects. We find that when the manufacturers’ products are very different in terms of attractiveness, the first effect dominates while the second effect is stronger when products are comparable. Finally, our findings require that retailers communicate the assortment strategy properly: retailers should not disclose the identity of the chosen manufacturers, but should commit to a given assortment breadth.
Trinta anos da escala Clinical Dementia Rating: o que sabemos sobre o CDR?
Authors: Pinto Roberta Borlido Ribeiro , Perez Mariangela
Published: March 2018

Introdução: Há uma crescente demanda por instrumentos padronizados, tanto para o rastreio quanto para o diagnóstico de demência, em ambientes de assistência e de pesquisa.  A escala Clinical Dementia Rating (CDR) foi desenvolvida há 30 anos, permite uma avaliação global cognitiva e funcional, e foi submetida a adaptações ao longo dos anos. Objetivos: Detalhar o desenvolvimento do CDR, com ênfase na cronologia das principais publicações e nas validações disponíveis no Brasil. Método: Revisão narrativa por meio de busca eletrônica no Pubmed e em referências bibliográficas dos artigos identificados. Foram selecionados 23 artigos. Resultados: O CDR foi desenvolvido por Hughes no Memory Aging Project, da Universidade de Washington, em 1977, e publicado no Bristish Journal of Psychiatry, em 1982. É composto por um questionário estruturado e uma escala que avaliam seis domínios cognitivos: memória, orientação, julgamento e resolução de problemas, assuntos da comunidade, casa e lazer e autocuidado. Os indivíduos são classificados em quatro categorias: 0 = ausência de demência; 0.5 = demência questionável; 1 = demência leve; 2 = demência moderada; e 3 = demência avançada. Em 2008, uma simplificação da pontuação foi proposta e validada, usando a soma de cada domínio, chamada Sum of Box (CDR-SOB). No Brasil, foram identificados dois estudos de validação do CDR e um estudo do uso do CDR-SOB. Conclusões: O CDR é um instrumento útil com alta confiabilidade na avaliação das demências, com duas validações disponíveis no Brasil. As versões mais recentes parecem possibilitar uma melhor avaliação dos estágios iniciais dos quadros demenciais.Descritores: Clinical Dementia Rating; Validação; Demência.

Identifying the Correlates and Barriers of Future Planning Among Parents of Individuals With Intellectual and Developmental Disabilities
Authors: Burke Meghan , Arnold Catherine , Owen Aleksa
Published: March 2018

Although individuals with intellectual and developmental disabilities (IDD) are living longer lives, fewer than half of parents of individuals with IDD conduct future planning. The correlates and barriers to future planning must be identified to develop targeted interventions to facilitate future planning. In this study, 388 parents of individuals with IDD responded to a national, web-based survey. Participants who were older, more educated, attended more parent training and support activities, and had children with fewer functional abilities, were more likely to engage in future planning. Reported barriers to future planning included: (a) lack of available services, (b) financial challenges, (c) reluctance of family members, (d) lack of time, (e) the emotional nature of future planning, (f) inertia, and (g) a lack of family members to be caregivers. Implications for policy, practice, and future research are discussed.

Authors: Karpelyev Vladimir A. , Philippov Yury I. , Averin Artem V. , Boyarsky Maxim D. , Gavrilov Dmitriy A.
Published: March 2018

Background: The efficacy of the treatment of type 1 diabetes can be markedly improved using artificial pancreas (AP), which is a technology to automatically control blood glucose levels.
Aim: In this paper, we propose the construction of a controller for controlling the automated delivery of insulin in AP based on a proportionalintegralderivative (PID) algorithm using intraperitoneal (IP) insulin delivery.
Methods: The project used rapid-acting insulin in the IP space when setting up a PID controller with feedback to ensure the safe and efficient delivery of insulin. The controller was configured to satisfy feedback insulin present in blood. Controller check was performed In Silico using the metabolic simulator UVA|Padova T1DMS on 10 virtual patients.
Results: The proposed controller design has time to reach 83% within the glycaemic range of 70140 mg/dl (3.97.8 mmol/l), without time spent in hypoglycaemia.
Conclusions: In a future study we plan to test this controller in vivo to evaluate its performance in vivo.

Published: March 2018

Human action recognition is a vibrant area of research with multiple application areas in human machine interface. In this work, we propose a human action recognition based on spatial graph kernels on 3D skeletal data. Spatial joint features are extracted using joint distances between human joint distributions in 3D space. A spatial graph is constructed using 3D points as vertices and the computed joint distances as edges for each action frame in the video sequence. Spatial graph kernels between the training set and testing set are constructed to extract similarity between the two action sets. Two spatial graph kernels are constructed with vertex and edge data represented by joint positions and joint distances. To test the proposed method, we use 4 publicly available 3D skeletal datasets from G3D, MSR Action 3D, UT Kinect and NTU RGB+D. The proposed spatial graph kernels result in better classification accuracies compared to the state of the art models.
Indian classical dance action identification using adaptive graph matching from unconstrained videos
Authors: V.V. Kumar K , V.V. Kishore P
Published: March 2018

Extracting and recognizing complex human movements from unconstraint online video sequence is a challenging task. In this work the problem becomes complicated by the use of unconstraint video sequences belonging to Indian classical dance forms. A new segmentation model is developed using discrete wavelet transform and local binary pattern features for segmentation. We also explore multiple feature fusion models with early fusion and late fusion techniques for improving the classification process. The extracted features were represented as a graph and a novel adaptive graph matching algorithm is proposed. We test the algorithms on online dance videos and on an Indian classical dance dataset prepared in our lab. The algorithms were tested for accuracy and correctness in identifying the dance postures.

Published: March 2018

A compact circularly polarized antenna having x-slot in the parasitic patches have been proposed in this article. Four driven patches which are capacitively loaded with the help of the feeding loop and four parasitic patches which generate circular polarization because of the sequentially rotated structures are noticed in the proposed modal. With combination of the CP mode with the feeding loop we can observe the broadened axial ratio bandwidth. Comparative analysis has been observed for each side facing driven elements and side and edge facing parasitic elements with X-slot have been observed. The proposed antenna works at the bands of 5.04-5.83GHz and 6.34-6. 81GHz which works for WLAN application. The proposed modal and its iterations have been analyzed using ANSYS EM Software. The results show an enhanced impedance bandwidth of 22 percent and axial ratio bandwidth of over 15percent has been noticed in the proposed modal. A constant gain has been noticed all over the analyzed modals.
Enhanced replica detection scheme for efficient analysis of intrusion detection in MANET
Authors: Bakeyalakshmi P. , Mahendran S. K.
Published: March 2018

Nowadays, detection scheme of intrusion is placing a major role for efficient access and analysis in Mobile Ad-hoc network (MANET). In the past, the detection scheme of Intrusion was used to identify the efficiency of the network and in maximum systems it performs with huge rate of false alarm. In this paper, an Effective approach of the Enhanced Replica Detection scheme (ERDS) based on Sequential Probability Ratio Test (SPRT) is proposed to detect the malicious actions and to have a secure path without claim in an efficient manner. Also, provides strategies to avoid attacker and to provide secure communication. In order to have an efficient analysis of intrusion detection the proposed approach is implemented based on the anomaly. To achieve this, the detection scheme is established based on SPRT and demonstrated the performances of detection with less claim. The simulation results of control overhead, packet delivery ratio, efficient detection, energy consumption and average claims are carried out for the analysis of performance to show the improvement than the existing by using the network simulator tool. Also, the performance of the proposed system illustrated the detection of intrusion in the normal and attacker states of the network.
Measuring distinct regions of grayscale image using pixel values
Authors: Jeyalaksshmi S. , Prasanna S.
Published: March 2018

Grayscale is a series of shades of gray without apparent color. The total absence of transmitted or reflected light, which is the darkest shade, black. The total reflection or transmission of light at all observable wavelengths, which is nothing but lightest possible shade i.e., white. Intermediate shades of gray are characterized by equal brightness levels of the primary colors (red, green and blue) for transmitting light, or equal amounts of the three primary pigments (magenta,cyan, and yellow) for reflected light. This paper focuses mainly on measuring the properties of objects in a grayscale image using Regionprops to calculate the standard Deviation. This is achieved by segmenting a grayscale image to get objects of a binary image. Although, the common problem of including chromatic values to a grayscale image has objective solution,not exact, the present approach tries to provide an approach to help minimize the amount of human labor required for this task. We transfer the source’s whole color “mood” to the target image by matching texture information and luminance between the images rather than selecting RGB colors from a group of colors to an individual color components. We pick out to transfer only chromatic information and retain the target image’s original luminance values. Further, the procedure is improved by permitting the user to match areas of the two images with rectangular swatches. It is essential to develop grayscale image pixel value, resultant to each object in the binary image to inspect the original grayscale image.Based on the original grayscale image pixel values, the pixel value properties in grayscale image are used to do routine calculations.

Aluminium/graphite composites are the need of modern times for addressing the fuel saving issues. The graphite in such composites act as solid lubricant and it reduce external fuel requirements. But such composites are having degraded mechanical properties due to the graphite content in composite. In order to solve the negative effect of graphite on mechanical properties of LM13/Gr self-lubricating composite this study was conducted to find out the mechanical properties of LM13/B4C/Gr Metal Matrix Composites. Boron carbide was selected as reinforcement because of its better reinforcement properties compared to alumina and silicon carbide. The properties of the hybrid composites were compared with the LM13/Gr self-lubricating composite to study the enhancement in mechanical properties that has been caused by the boron carbide particles. Using computerized universal testing machine and rock-well hardness tester mechanical properties such as hardness and tensile strength were tested. Pin on disk testing machine was used to analyse the wear behavior. The test results indicates that by raising weight % of boron carbide particles in the LM13, tensile strength and hardness of the hybrid composites was increased compared to self-lubricating composite accompanied by better tribological properties.

In this work, our research focuses on a design for request distribution and associated security attacks in dense vehicular ad hoc networks (VANET) and also sparse VANET that creates a delay tolerant network (DTN). Generally vehicles are stratified into clusters; we presented a reliability based clustering which has been designed for VANET. Cluster creation is according to complicated clustering metric that considers density of relation graph, link value and also traffic conditions. Since the ones in specific time and location are always affecting with the similar pattern of the direction and also velocity. A vehicle communicates with other vehicles or it’s nearest Road Side Unit (RSU), which provides an access for a local cloud for sending appeals. We define the formal security model k-anonymization of privacy preserving aggregated transmission evidence generation (ATEG) in our proposed trust based VANET network (TBVN). It is required that both the individual vehicle velocity and the average velocity of vehicle clusters should be well protected from the semi-trusted vehicular cloud and the malicious running vehicles. Therefore, except for the traditional security requirements such as data secrecy and authentication, unique safety and privacy concerns are emergently should be rectified.

Recognition of face has been turned out to be the most important and interesting area in research. A face recognition framework is a PC application that is apt for recognizing or confirming the presence of human face from a computerized picture, from the video frames etc. One of the approaches to do this is by matching the chosen facial features with the pictures in the database. It is normally utilized as a part of security frameworks and can be implemented in different biometrics, for example, unique finger impression or eye iris acknowledgment frameworks. A picture is a mix of edges. The curved line potions where the brightness of the image change intensely are known as edges. We utilize a similar idea in the field of face-detection, the force of facial colours are utilized as a consistent value. Face recognition includes examination of a picture with a database of stored faces keeping in mind the end goal to recognize the individual in the given input picture. The entire procedure covers in three phases face detection, feature extraction and recognition and different strategies are required according to the specified requirements.

The general undertaking of the product building is to guarantee conveyance of superb programming to the end client. To ensure great programming, it is required to test programming. Testing is a critical constituent of programming building. In programming testing there are number of fundamental issues like compelling age of experiments, prioritization of experiments which should be handled. This mechanized test structure predominantly relies upon these four angles: test system, experiment age, test execution and test assessment. Test methodology is an accumulation of systems that decides the testing way to deal with be trailed by the testing group. The experiment age alludes to the age of experiments in light of the given application. The test execution briefs about the execution of those tests at that point contrasting the normal outcome and genuine outcome. The test assessment explores the experiments and causes us to produce test rundown report and programming quality confirmation report consequently. The aim of delivering this device is to produce test cases naturally and to diminish the cost of testing notwithstanding collect the season of determining experiments physically. Subsequently this framework enhances general nature of the product.

Mutation testing is a modern approach which gives more appropriate results. In comparison to traditional approaches, it gives high quality output. Previously it is not used mostly because of its high cost factor. This is because mutation testing deals with white box testing. White Box testing checks every module of the software in detail. If we use this it takes a lot of time and money. Recent approaches which came in mutation testing made it easy to implement for any software. Mutation take a look ating could be a fault based mostly testing technique within which mutants area unit generated within the program and apply totally different test cases on the mutants. Some mutants are killed and some are alive. On the bottom of killed and alive mutants, mutant score is calculated. Based on the mutants which are alive the test cases can be improvised there by the quality of the source code is increased. we propose a tool which gives more effective output of testing. We propose a tool which takes the outputs of various static tools available and combines it with the outputs of dynamic tools available. Our proposed tool includes outputs of available tools like Jester, Mujava, PMD to effectively detect the vulnerabilities and produce high quality software as output.

Record Linkage and Deduplication are the two process that are used in matching records. Matching of records is done to remove the duplicate records. These duplicate records highly influence the outputs of data mining and data processing. If the matching of records is done on the single database, it is called Deduplication. In Deduplication we check for the duplicate records in the single database. Unlike deduplication if the matching of the records is done on the several databases it is called as record linkage. In this paper we also discuss about the indexing technique called as traditional blocking which is used to remove non matching pairs that leads to the less number of record pair to be compared.
