Clustering Analysis of Greedy Heuristic Method in Zero_One Knapsack Problem
Authors: Selvi V.
Published: June 2018

Knapsack problem is a surely understood class of optimization problems, which tries to expand the profit of items in a knapsack without surpassing its capacity, Knapsack can be solved by several algorithms such like Greedy, dynamic programming, Branch & bound etc. The solution to the zero_one knapsack problem (KP) can be viewed as the result of a sequence of decision. Clustering is the process of resolving that type of applications. Different clustering application for grouping elements with equal priority. In this paper we are introducing greedy heuristic algorithm for solving zero_one knapsack problem. We will exhibit a relative investigation of the Greedy, dynamic programming, B&B and Genetic algorithms regarding of the complexity of time requirements, and the required programming efforts and compare the total value for each of them. Greedy and Genetic algorithms can be used to solve the 0-1 Knapsack problem within a reasonable time complexity. The worst-case time complexity (Big-O) of both algorithms is O(N). Using the greedy method, the algorithm can produce high quality clusters while reduce time the best partioning avoid the memory confinement problem during the process.

Authors: Gumber Gunjan , Rana Jyoti
Published: June 2018

In India, the concept of organic food is gaining widespread acceptability. Consumers are becoming more conscious about their health and are looking for food that serves as a promising alternative. Corporates, NGOs, Spiritual leaders and Government are also promoting this food, as it is free from irradiation, chemicals and artificial additives. A number of organic food brands are available in the market. The main objective of this study is to find out the level of brand awareness and its influence on purchase of organic grocery. The data was collected from 150 organic consumers in National Capital Region (Delhi, Gurgaon, Faridabad and Noida) through a structured questionnaire. Questions related to brand recall, brand recognition and purchase of organic grocery were asked. It was found that in general, there is a low level of brand awareness among consumers, and those who have high level of awareness; they consume organic grocery more often. The study will help corporates to make effective communication and brand-building strategies.

Effective Non-Linear Prefiltering Method for Coloured Edge Detection of Noisy Images
Authors: Kaur Ranveer , Dhaliwal Gurleen Kaur
Published: June 2018

This paper addresses a method to obtain color edge detection for images corrupted with Gaussian noise and impulse noise, to correctly reproduce distinct, continuous edges based on non-linear prefiltering followed by block-by-block rotations to locate the edges in all orientations. In this work our major goal is to eliminate the noise from noisy image as edges are the most important detailing areas in an image and addition of noise corrupt these edges which result in lack of clarity. In our proposed work we are proposing a efficient hybrid algorithm to preserve the edges of image based upon Canny operator. Our proposed scheme is based on rotation, median filtering and performing morphological thinning. This scheme is evaluated on basis of FOM(Figure Of Merit) parameter and our result are efficient than previous technique. This paper is divided into some sections.

Intrapersonal Conflict: The Autoimmunity in Women Entrepreneurship
Authors: Mitra Anindita
Published: June 2018

India has created economic opportunities and provided economic liberalization to Indian women by empowering them through entrepreneurship prominently since the Sixth Five Year Plan (1980-85). The male dominated society has since then seen a pronounced reduction of socio-cultural tax paid by women and a widespread improvement in women literacy, employment, financial independence and government’s entrepreneurial development schemes. Yet, the representation of women entrepreneurs in the economy especially from the urban sector is considerably low. Among the problems a woman entrepreneur encounters, a crucial challenge that hinders decision making and repels her natural success gene is her conflict with self; the intrapersonal conflict. There has not been much probe into this particular aspect that works slowly within and may eventually extinguish the urge of economic independence.  Hence this theoretical study is an effort to highlight the fact that, while psychological traits such as aspiration, confidence, self-worth, self-esteem, self-actualization and internal locus of control stimulate women to dart towards economic independence, the conflict among them can also hold them back from it, creating the “autoimmune system” in the process. Reviews from various research and e-books and secondary data from Ministry of Statistics and Program Implementation (MOSPI), National Sample Survey Office (NSSO), 6th Economic Census have been used to substantiate the facts.

Discusiones sobre la autonomía en la recepción de los aportes dependentistas al campo de las Relaciones Internacionales y contribuciones recientes desde el enfoque de cadenas globales de valor
Authors: Treacy Mariano
Published: June 2018

La teoría de la dependencia es reconocida en el mundo de las Relaciones Internacionales como una de las principales contribuidoras al Campo desde los países de América Latina. En este trabajo nos proponemos el objetivo de identificar las características de la recepción de los aportes dependentistas bajo la hipótesis de que esta ha estado mediada por los desarrollos de la Escuela de la Autonomía Latinoamericana y no por las contribuciones de quienes son considerados los autores dependentistas canónicos en el campo de la Economía Política. Lo que observaremos es que el concepto de autonomía que se trabaja desde la escuela latinoamericana es considerablemente diferente del que se trabaja desde la Economía Política. Además de un balance crítico, se realiza una propuesta para incorporar al marco del análisis de la autonomía la problemática de las cadenas globales de valor
Decolorization and Biodegradation of basic violet dye by fungal- bacterial consortia
Authors: Deivasigamni Manimaran Rajavelu , Ramalingam P.
Published: June 2018

The present study was aimed to test the ability of Penicillium citrinum MTCC 8009, Aspergillusterreus MTCC 3006, Bacillus cohnii and their consortia to decolorize basic violet dye. Different parameters such as initial dye concentration, dye to inoculum ratio and period of incubation were studied for the decolourization of the dye. The developed fungal-bacterial consortia exhibited maximum percent decolorization (92%) ability when compared to the treatment of dyes by individual microbes. Percent decolorization of basic violet dye (92%) was more efficient using fungal-bacterial (Penicillium citrinum and Bacillus cohnii) consortia than with individual cultures. Phyto-toxicity results indicated that bacterial-fungal consortia (Penicillium citrinum and Bacillus cohnii) treatmentÂ  was believed to degrade the dyes to non-toxic intermediates. The FTIR analysis also revealed that decolorization of basic violet dyes was due to its degradation.

The aim of this article is to explore teaching in a leisure-time centre based on teaching as an entity of care, learning and development. Reforms that characterized Swedish educational systems since the 1980s have in many ways changed the leisure-time centre; and, in The Education Act and the national curriculum, a shift from care to education can be noticed. A revised task for the leisure-time center lifts concepts such as teaching and achievement in line with the primary school's task. The article focuses on a policy process where a specific activity is planned, implemented, documented, evaluated and followed up by teachers in the leisure-time center. The enactment of teaching is analyzed through policy enactment theory, and data is generated by ethnographical method in a case study in a leisure-time centre. The result shows an entity of care, learning and development when teaching focuses on play and development of social and relational abilities, in line with the leisure-time center's task.

Authors: Lopes Paulo Roberto do Canto , Gaspar MaDu , Cavalcante Gomes Denise Maria
Published: June 2018

A retomada recente da pesquisa arqueológica no sambaqui Porto da Mina (PA-SA-5), litoral do Pará, foi feita a partir da abordagem metodológica proposta pela Arqueologia Estratégica, buscando compreender aspectos associados à formação do registro arqueológico. O primeiro autor analisou a coleção formada por Mário Simões nas décadas de 1960/70 e obteve novos dados com o estudo da seção de perfil de uma das áreas escavadas e com a análise de material da coluna zooarqueológica retirada do sambaqui. A análise da cerâmica proveniente das duas pesquisas destaca a inexistência de vasilhames inteiros e pequenas dimensões dos fragmentos, características que levaram a considerar a hipótese de que os vasilhames cerâmicos foram utilizados em diversas atividades rotineiras e, posteriormente, seus fragmentos reutilizados como material construtivo para consolidação do sambaqui.

Published: June 2018

Este trabalho versa sobre a ocupação da região da laguna de Santa Marta, litoral sul catarinense, por grupos construtores de sambaquis. O período considerado vai aproximadamente de 7.5 a 0.9 cal ka aP, ao longo do qual a região esteve continuamente ocupada pelos grupos sambaquieiros. O resultado mostra que a dinâmica do processo de construção de sambaquis na região pode ser dividida em fases, uma de expansão, entre 7.5 e 3.0 ka aP, e outra de retração, de 3.0 a 0.9 ka aP. Ao longo de todo o período percebe-se um padrão de agregação dos sítios, com a região sendo particionada e compartilhada por vários focos de ocupação. Este padrão de territorialidade se manteve ao longo do tempo.
O Termo de Ajuste de Conduta entre as práticas do IPHAN para a Arqueologia: avaliação de uma década de conflitos e negociação

Published: June 2018

O artigo interroga a recorrência ao termo de ajustamento de conduta (TAC) dentre as práticas do IPHAN direcionadas à proteção do patrimônio arqueológico no âmbito do licenciamento ambiental. Utilizo a abordagem oferecida pelo institucionalismo histórico, e partilho da ideia de que o TAC pode atuar como um mecanismo flexibilizante às etapas asseguradas pelo licenciamento. Por meio de um levantamento realizado junto às Superintendências do IPHAN, são debatidas características pungentes dos casos concentrados entre o período de 2002 e 2012, como a proeminência das obrigações compensatórias sobre as demais soluções oferecidas pelo ajuste, e a proposição de medidas que escapam à proteção do patrimônio arqueológico ameaçado.

To date, only several microporous, and even fewer nanoporous, glasses have been produced, always via post synthesis acid treatment of phase separated dense materials, e.g. Vycor glass. In comparison, high internal surface areas are readily achieved in crystalline materials, such as metal-organic frameworks (MOFs). It has recently been discovered that a new family of melt quenched glasses can be produced from MOFs, though they have thus far have lacked the accessible and intrinsic porosity of their crystalline precursors. Here, we report the first glasses that are permanently, and reversibly porous toward incoming gases, without post synthetic treatment. We characterized the structure of these glasses using a range of experimental techniques, and demonstrate pores in the 4-8 angstrom range. The discovery of MOF-glasses with permanent accessible porosity reveals a new category of porous glass materials, that are potentially elevated beyond conventional inorganic and organic porous glasses, by their diversity and tunability.

The tests were carried out with the iperf3 network bandwidth measurement tool, and while transferring data using the FTP protocol over both IPv4 and IPv6.
Numerical Evaluation of Electromagnetic-wave Penetration at Normal Incidence through an Inhomogeneous-wave Approach
Authors: Calcaterra Alessandro , Frezza Fabrizio , Simeoni Patrizio , Tedeschi Nicola
Published: June 2018

This paper presents numerical scenarios concerning penetration in a lossy medium that can be obtained by radiating inhomogeneous electromagnetic waves. Former papers approached this problem, both analytically and numerically, ﬁnding requirements and limits of the so-called “deeppenetration” condition, which consists of a wave transmitted in a lossy medium having an attenuation vector whose direction forms the angle of ninety degrees with the normal to the separation surface. The deep-penetration condition always requires an oblique incidence, therefore is not practical in many applications. For this reason, we are interested here in ﬁnding whether an inhomogeneous wave guarantees larger penetration than the one obtainable with homogeneous waves, even when the incident wave is normal to the separation surface between two media, i.e. when the deep-penetration condition is not satisﬁed. We are also interested in verifying numerically whether the lossy-prism structure may achieve larger penetration than the one obtainable through traditional leakywave antennas, and we also wish to propose a lossy-prism design more realistic than the one previously presented in the literature.

Authors: Sabri Tahmid
Published: June 2018

Internalizing the value of character in primary school children is fundamental, but the reality in school teachers is still difficult to do because of the inappropriateness of the approach used. The solution needs to be addressed by a scientific approach so that this study is expected to describe the design of learning to its implementation. This research uses the method of description through class action done by students peer teaching fellow colleagues. The findings show that the design of value internalization in scientific learning can be done well by the students from the mapping of themed concepts and sub-themes to the determination of KI, KD, Indicator, objective formulation, activities, and integrated evaluation of attitudes, skills, and knowledge in an integrated manner. Similarly, the well-packed implementation of the initial activity, the core activities to the final activity, it looks the scientific nuances that deliver the internalization of values on the participants of learning that will personally on themselves as individuals who are pious, noble, intelligent, skilled, creative , discipline, independence, responsibility and democratic. This achievement cannot be separated from the various obstacles experienced by students but can be overcome, so as not to reduce the acquisition of expected learning outcomes. The results of this study are expected to be used as a basic capital for the development of thematic learning either for the needs of students who are teaching in elementary school or for the development of integrated therapeutic learning in elementary school.
Statistical Monitoring and Optimization of Electrochemical Machining using Shewhart Charts and Response Surface Methodology
Authors: Maged Ahmed , Haridy Salah , Shamsuzzaman Mohammad , Alsyouf Imad , Zaied Roubi
Published: June 2018

The response surface methodology (RSM) and Shewhart control charts have been widely used in manufacturing to reduce variation, improve quality and optimize the output. This article proposes an application of individuals & moving range chart (I&MR) and RSM in electrochemical machining. The Shewhart-type I&MR control chart and RSM are combined together in an effective way to successfully guarantee the statistical control of the surface roughness (Ra) of the items produced by wire electrochemical turning, and meanwhile optimize Ra by exploring the optimal values of the machining parameters including applied voltage, wire feed rate, wire diameter, rotational speed and overlap distance. The conducted experiments reveal that the optimal values of the aforementioned factors are 23.67, 0.5, 0.2, 900 and 0.02, respectively.  A second-order regression model is also developed to predict the output (Ra) at different combinations of the input parameters. The developed regression model can predict the output values with a determination coefficient (R2) of 96.9%. The proposed combined scheme of Shewhart charts and RSM can be employed in other manufacturing processes and even in different service sectors to efficiently enhance the performance and reduce the cost.

Published: June 2018

The aim of this research was to evaluate the level of greenhouse gas emission from broiler chicken farming industry in Malaysia. In order to achieve that, Life Cycle Assessment method was chosen as a framework to complete the task. A case study was conducted at a broiler chicken farm to gather the data and information related to the broiler chicken production. Cradle-to-gate assessment including distribution stage was conducted based on the ISO14040/1044 guidelines. Inventory data for this case study was gathered in collaboration with one of the selected case study broiler chicken farm company. Greenhouse gas emission that consists of several most affected gases such as carbon dioxide, methane and nitrous oxide was studied. Result shows that the highest carbon dioxide emission came from manure, which accounted for 1,665,342 kg CO2 equivalent per total broilers while the highest methane emission came from feed, which accounted for 126,207.84 g CH4 equivalent per total broilers. For nitrous oxide emission, the highest values came from bedding which accounted for 20,316.87 g N2O equivalent per total broilers in the commercial modern broiler chicken farm. In this case study, it can be concluded that manure gives the most prominent effect to the greenhouse gas emission followed by feed and bedding materials.
Effect of UV Radiation on Degradation of Durian Skin Fibre Composite
Authors: Abd Rashid Siti Munirah Salimah , Anuar Hazleen , Mohd Apandi Siti Nur E'zzati , Buys Yose Fachmi
Published: June 2018

Durian skin fibre (DSF) reinforced high-density polyethylene (HDPE) composite was fabricated by melt-blending and then compression moulded. As DSF is polar and hydrophilic in nature, while HDPE is non-polar and hydrophobic, thus the adhesion between them is low. Therefore, maleic anhydride-grafted-polyethylene (MAPE) was added to enhance the interaction of HDPE and DSF. This paper highlight the effect of MAPE on UV degradation exposure on HDPE/DSF composite. DSF content from 10, 20, 30 and 40 wt% were immersed in water for 70 days. In the absence of MAPE, water absorption increased with DSF loadings. Furthermore, tensile properties of HDPE/DSF composite was degraded after 500, 1000 and 2000 h of UV radiation exposure. Morphological observation under SEM showed that the fibre and matrix became less interacted after exposed to UV radiation. Voids and gaps between HDPE and DSF in the presence of MAPE were reduced as revealed under SEM micrographs. The colour index of the HDPE/DSF composite was increased and became whiter with UV radiation exposure. This showed that MAPE significantly improved the interaction of HDPE/DSF composite.

The paper aims to improve understanding of the role played by accounting in its function of governmentpractice, considering the interfacing function of the Real Albergo dei Poveri of Palermo charity. Michel Foucault’sgovernmentality framework is adopted in order to explore the labour organisation within the Real Albergo deiPoveri of Palermo, where a silk manufacturer, the Real Opificio delle Sete (Royal Silk factory), was establishedin 1790 to exploit the workforce hosted in the institution. The paper analyses the accounting system established tomanage the commodified and forced labour of poor female inmates in relation to a central issue—the social controlpromoted by central government. The idea is to demonstrate that work was the means to carry on the social controlof people considered alien and not integrated by the society of the time, while the accounting system was the tool.The study uses documents from Palermo’s State Archive about the foundation and internal organisation of theReal Opificio delle Sete and account books from the institution and silk manufacturer to verify the role of labourand its measurement, highlighting accounting based on the checking and reporting system. Furthermore, the paper,by means of the accounting system, examines the organisation of work and internal management, and the allocationof wealth in the form of healthcare, social security and housing.

A proposal of the model of international marketing research as information basis in game theory
Authors: Stanetić Vedran
Published: June 2018

Analyzing the theory of games it can be noticed that the moves and strategy of the players are not sufficiently based on the relevant information. Most often, the only information that game strategy methodologists advocate is rationality, which certainly does not have to be the case in all games. In addition, the greater practical representation of game theory is avoided by the numerous assumptions and limitations set by the particular model of a particular game, and whose practical foundation does not always have to be realistic.

An interdisciplinary combination of international marketing research and game theory would create a new quality for one and the other discipline. However, the biggest benefit would be for business or marketing decision makers, especially in industrial marketing. The aim of the paper is to present a new model that, in conditions of globalized business, will provide information support from the international market for business decision making using the theory of games. The proposed model is in the form of an information system for international marketing research in support of business decision-making.

The first part of the paper is devoted to the analysis of game theory, in particular the analysis of assumptions and limitations for its greater practical application. A model that would partially overcome the described problems is proposed in the second part of the paper. The methodology used in the paper is also characteristic of marketing research and game theory.

Public services are provided by government and have been traditionally supply-oriented. Changing citizen expectations put pressure on government agencies and public sector organizations to be accountable for efficiency and effectiveness. Further, the quest to enhance international competitiveness by ranking high in the echelons of world’s best governments, led to the adoption of proven marketing philosophy and methodologies in the domain of public service as well. The present study aims at examining the impact of Service quality, Reputation and Consumer Engagement on Customer Perceived Value, Satisfaction and Loyalty for an important public service viz., Dubai Metro which operated in an intensely competitive market. The study aimed at developing and empirically testing a structural model of travel behavior based on variables such as satisfaction, value, quality, reputation and engagement that have been found to drive loyalty in various industry settings. An understanding of the drivers of satisfaction contributes to the government’s aim of delivering services that rival the best in the private sector; contributes to the neglected public service context in the service management literature and captures insights that help the shift to service-dominant thinking within the public sector.

Women entrepreneurship is today one of the major factors contributing to a country’s prosperity and to the global market in general. However, females still own and manage significantly fewer businesses than men. Especially, women in developing countries face disadvantages and discrimination. Compared to their male counterparts, women in developing countries have a lower level of education and skill training. Another important challenge for female entrepreneurs in developing countries is the issue of safety and protection of women, especially those operating in the informal economy. The most female entrepreneurs in developing economies are motivated to start their businesses out of necessity, reflecting lack of employment alternatives or dissatisfaction with existing employment. The overall nature and extent to which female entrepreneurship can develop in developing economies is greatly influenced by project to strengthening them. In line with this, the aim of our research was to explore the impact of one of these programmes -GWIN project and its effect to empowering women in Nigeria. Based on the findings, it was concluded that GWiN project plays a significant role in the economic development of women in Nigeria through the benefits of various supports to them.

Mankind caused a lot of harm to their environment unintentionally during agriculture. Thus nowadays production techniques that are compatible with nature, making the right use of the resources, targeting sustainable development, looking after animal welfare are beginning to spread throughout the world. Especially organic agriculture among those techniques gained a seat as it depends on customer preference. Organic agriculture that has the following five fundamental features: compatibility to nature, self sufficiency, sustainability, welfare, traceability began with the production of dried grape, dried figs, dried apricots and nuts in our country during the 1980s with the contractual agriculture system intending to export. During the following years, hardshell and dried fruits, frozen fruits and vegetables, fresh fruits and vegetables, spices and legumes followed the previous ones in export. Also, production and exportation of rose water, rose oil, olive oil, cotton and textile products increased considerably. In our country where there is a wide variety of products for organic agriculture, in eastern black sea region tea and nuts are the most cultivated products. Organic agriculture is carried out in every province of the region, the contribution of provinces in percentage as follows: Rize 42%, Ordu 25%, Artvin 13%, Trabzon 10%, Gumushane and Giresun 5%. Organic stock raising is done only in Gumushane and Ordu. Gümüşhane has the most promising potential for organic stock raising.
Light-Weight Integration of SAT Solving into First-Order Reasoners – First Experiments
Authors: Schulz Stephan
Published: June 2018

We describe a light-weight integration of the propositional SAT solver PicoSAT and the saturation-based superposition prover E. The proof search is driven by the saturation prover. Periodically, the saturation is interrupted, and all first-order clauses are grounded. The resulting ground problem is converted to a propositional format and handed to the SAT solver. If the SAT solver reports unsatisfiability, the proof is extracted and reported on the first-order level. First experiments demonstrate the viability of the approach and suggest future extensions. They also yield interesting information about the structure of the search space.
Using Vampire with Support for Algebraic Datatypes in Type Soundness Proofs
Authors: Grewe Sylvia , Pacak André , Mezini Mira
Published: June 2018

In our ongoing project VeriTaS, we aim at automating soundness proofs for type sys- tems of domain-specific languages. In the past, we successfully used previous Vampire versions for automatically discharging many intermediate proof obligations arising within standard soundness proofs for small type systems. With older Vampire versions, encoding the individual proof problems required manual encoding of algebraic datatypes via the theory of finite term algebras. One of the new Vampire versions now supports the direct specification of algebraic datatypes and integrates reasoning about term algebras into the internally used superposition calculus.

In this work, we investigate how many proof problems that typically arise within type soundness proofs different Vampire 4.1 versions can prove. Our test set consists of proof problems from a progress proof of a type system for a subset of SQL. We compare running Vampire 4.1 with our own encodings of algebraic datatypes (in untyped as well as in typed first-order logic) to running Vampire 4.1 with support for algebraic datatypes, which uses SMTLIB as input format. We observe that with our own encodings, Vampire 4.1 still proves more of our input problems. We discuss the differences between our own encoding of algebraic datatypes and the ones used within Vampire 4.1 with support for algebraic datatypes.
An Inference Rule for the Acyclicity Property of Term Algebras
Authors: Robillard Simon
Published: June 2018

Term algebras are important structures in many areas of mathematics and computer science. Reasoning about their theories in superposition-based first-order theorem provers is made difficult by the acyclicity property of terms, which is not finitely axiomatizable. We present an inference rule that extends the superposition calculus and allows reasoning about term algebras without axioms to describe the acyclicity property. We detail an indexing technique to efficiently apply this rule in problems containing a large number of clauses. Finally we experimentally evaluate an implementation of this extended calculus in the first-order theorem prover Vampire. The results show that this technique is able to find proofs for difficult problems that existing SMT solvers and first-order theorem provers are unable to solve.
