Multi Objective Optimization of Multimodal Two-Way Roundtrip Journeys
Authors: Gündling Felix , Hoch Pablo , Weihe Karsten
Published: April 2019

Multi modal journeys often involve two trips: one outgoing and one return trip, as in many cases, the traveller would like to return to his starting point. If a car or bike was used in combination with public transportation (i.e. park \& ride), this introduces a dependency between outward and return trip: both must include the same parking place. Optimizing both trips independently may yield suboptimal results. We consider the multi modal two-way roundtrip problem and propose several algorithms. All proposed algorithms compute journeys that are optimal regarding multiple criteria. Our study with realistic scenarios based on real data shows promising results.

Published: April 2019

World oil prices affect the stock market in developed and developing countries, including Indonesia. Therefore, development of the Indonesian economy is affected by the shocks of world oil prices and the stock market. This study characterized the impact and causal relationship between oil price shocks and stock market in Indonesia from 1996 to 2016. In this research, there are nine sectors of the stock market, there are sector agriculture, basic, consumer, finance, infrastructure, mining, miscellaneous industry, property, and trade. To analyze the impact of oil price shocks to Indonesia stock market, we employed an autoregressive vector model (VAR) methodology involving different lags for each regime. We examined that the dynamic relationship between changes in oil prices and stock market in Indonesia in each regime varied which was indicated by impulse response and variance decomposition value. The Granger Causality test found that there were one-way relationship between oil variable with infrastructure sector variable, oil variable with agricultural sector variable and oil variable with basic sector variable in Regime 2, Regime 3 there was one way relationship significantly between oil variable with infrastructure sector variable and Regime 4 also there were one-way relationship. One-way relationship significantly between oil variable with property sector variable, but not significant in Regime 1.

Marketplace is one of the most popular digital business in Indonesia. One of the category that grow in Marketplace X is shops that sell baby equipment or better known as babyshop. In order to provide the best service and keep the credibility of babyshop specialty shops, important to do qualitry monitoring on of them through clustering. Clustering based on store reputation assessment indicators consisting of variables that are categorical and numerical in scale. This study aims to classify babyshop on Marketplace X based on the characteristics of the store using cluster analysis with cluster ensemble based mixed data clustering (CEBMDC) based on the weigthed squeezer algorithm. This study use the stream data from 218 babyshop at Marketplace X which consists of service factors, reputation level, type and location of the babyshop. The optimal cluster results was into three clusters in which cluster one consists of 21% babyshop, cluster two 48% babyshop, and 31% babyshop at cluster three. The first cluster is a cluster with the tendency of the babyshop to be classified as good, the cluster two tend to have a normal (neutral) reputation, while members of cluster three has a for poor reputation.

Published: April 2019

Indonesia is pluralist a country with multi ethnics, cultures and religions. Religion is believed to provide guidance’s for humans life, however in other occasion it could become source of conflict. This happened due to monolithic belief which provides no space to accept the truth of other religions and cultures. This paper presents the meaning of ritual Perang Topat and lessons learned from the tradition of Sasak tribe who are Muslims and ethnic Bali who are Hindus.Perang Topat could be meaningful lessons learned in developing tolerance amongst different ethnics, culture and religions. It demonstrates that the Sasak ethnic and Balinese ethnic are able to live together in harmony both in daily lives and ritual ceremonies. Open communication and mutual understanding amongst ethnics is the key to sustain defferences. Therefore every one within the community do not provoc ofensive behaviour to other. Dialogue to find win win solutions is suggested as it it is demonstrated in the ritual. Thus this ritual need to be delivered so that it become lesson learnt in protecting unity.  Values of the ritual should be explored and deseminated so that community understand and implement  them. Key words: perang topat, lesson learnt, unity and differences

Estado, capitalismo y comunidades rurales. Procesos de producción de desigualdades sociales en Campeche, México
Authors: Dzib Can Ubaldo
Published: April 2019

Exploro los procesos de formación de ciertos grupos sociales, el Estado y el capital en una zona rural del Sur de Campeche. Argumento que el Estado no ha sido el creador primo de la vida social de los sujetos, sino parte de los procesos de ésta, en los que las formas y categorías del Estado han sido producidas de manera desigual por los grupos y clases para fijar las asimetrías creadas entre ellos. En Campeche, el Estado es el resultado institucional de la producción de categorías como nativos y colonos, mayas y mestizos, patrones y clientes, como grupos jerarquizados. Por lo tanto, el Estado no debe ser el punto de partida del análisis, ni de la democracia, si no se consideran las disparidades de las que procede y ayuda a producir.

Published: April 2019

Aim: We aimed to investigate the association of eNOS gene with Glu298-Asp and T-786C polymorphisms with Coronary artery disease (CAD) and to contribute to the elucidation of the genetic factors involved in the development of CAD. Patients and Methods: A total of 200 patients were evaluated. Severe CAD was defined as ≥ 50% stenosis in at least one of major coronary arteries and these patients were taken into the CAD group (n=144). Patients without stenosis were included in the control group (n=66). Results: After the evaluation of T-786C polymorphism, there was no significant dif-ference between TT (p=0,660), TC (p=0,73) and CC (p=0,634) genotypes between CAD and control groups. There was no significant difference between the groups in both dominant (p=0,439) and recessive (p=0,622) model comparisons. When Glu 298-Asp polymorphism was examined, there was no statistically significant difference between GG (p=0,836), GT (p=0,581) and TT (p=0,767) genotypes when the groups were compared according to genotype distributions. The groups were statistically similar according to both dominant (p=0,697) and recessive (p=0,485) model com-parisons. 

Conclusion: There was no statistical correlation between T-786 C and Glu 298-Asp polymorphisms and CAD. Similar studies with larger study populations should be conducted to clarify the role of T-786 C and Glu 298-Asp polymorphisms.

Background: Aplastic anemia (AA) is a hematologic disorder characterized by hypoplastic bone marrow and peripheral pancytopenia. The main symptoms are fatigue and bleeding. In the oral cavity, gingival bleeding is the common complaint.Case Management: A 18-year-old female patient referred from internal medicine department due to swelling of palate since 2 days before that interrupted eating activity. She routinely consumes Sandimun®100 mg tablets. A 2 x 1 cm black blood clot in anterior hard palate and ulcerative lesion at dorsal tongue regio 45 surrounded by necrotic area were found on intra oral examination. Patient was diagnosed with necrotizing ulcer-related neutropenia accompanied by AA-associated hemorrhagic bullae in the hard palate. Patient treated with mouthwash containing 0.1% hyaluronicacid and 1% feracrylum.Discussion: Immunosuppressant is the AA gold standard therapy. Cyclosporine (CsA) as imunosupressant is common drug to prevent T cells from attacking stem cells in bone marrow. The side effects of CsA is gingival hiperplasia.Conclusions: Gingival bleeding and gingival hiperplasia due to thrombocytopenia and the use of cyclosporine are vicious circles that need to be aware. With comprehensive management, good oral conditions will be obtained, therefore the quality of life can increase.
THE ROLE OF VITAMIN D SUPPLEMENTATION FOR HEAD AND NECK CANCER : A LITERATURE REVIEW
Authors: Permatasari Dewi Kania Intan , Sufiawati Irna
Published: April 2019

Background: Vitamin D has several roles, namely physiological function of calcium and bone metabolism, cell growth and differentiation, immune and cardiovascular function. Vitamin D deficiency can cause the risk of cancer. Head and neck cancer is one of the cancers that occur due to vitamin D deficiency in the body. This literature review was to asses and evaluate the impact and benefits of vitamin D supplementation for head and neck cancer.Discussion: A study found an association between vitamin D supplementation and a low risk of recurrence in conditions of high total vitamin D levels. Another study found a significant increase in quality of life (QOL). The primary mechanism of vitamin D action is mediated through binding of either 1,25(OH)2D3 (active form) or 25(OH)D (less active form) to the VDR, which is a member of the nuclear receptor superfamily of steroid and thyroid hormones with gene-regulatory and consequent anti-proliferative properties.Conclusions: Vitamin D supplementation provides a role in improving the condition of patients with head and neck cancer. Both in terms of suppressing recurrence and in terms of increasing quality of life

Physical Laws and Human Behavior: A Three-Tier Framework
Authors: Mousavi Shabnam , Sunder Shyam
Published: April 2019

Social sciences start by looking at the social-psychological attributes of humans to model and explain their observed behavior. However, we suggest starting the study of observed human behavior with the universal laws of physics, e.g., the principle of minimum action. In our proposed three-tier framework, behavior is a manifestation of action driven by physical, biological, and social-psychological principles at the core, intermediate, and top tier, respectively. More broadly, this reordering is an initial step towards building a platform for reorganizing the research methods used for theorizing and modeling behavior. This perspective outlines and illustrates how a physical law can account for observed human behavior and sketches the elements of a broader agenda.

Southern Hemisphere Breeding Stock D humpback whale population estimates from North West Cape, Western Australia
Authors: Kent Chandra Salgado , Jenner Curt , Jenner Micheline , Bouchet Phil J , Rexstad Eric
Published: April 2019

Estimates of the abundance of Breeding Stock D humpback whales (Megaptera novaeangliae) are key to the conservation and management of what is thought to be one of the largest populations of the species. Five years (2000, 2001, 2006, 2007 and 2008) of aerial surveys carried out over an eight-year period at North West Cape (Western Australia) using line transect methodology allowed trends in whale numbers to be investigated, and provided a base for comparison with estimates made approximately 400km south at Shark Bay (Western Australia). A total of 3,127 whale detections were made during 74 surveys of the 7,043km 2 study area west of NWC. Pod abundance for each flight was computed using a HorvitzThompson like estimator and converted to an absolute measure of abundance after corrections were made for estimated mean cluster size, unsurveyed time, swimming speed and animal availability. Resulting estimates from the migration model of best fit with the most credible assumptions were 7,276 (CI = 4,993–10,167) for 2000, 12,280 (CI = 6,830–49,434) for 2001, 18,692 (CI = 12,980–24,477) for 2006, 20,044 (CI = 13,815–31,646) for 2007, and 26,100 (CI = 20,152–33,272) for 2008. Based on these data, the trend model with the greatest r 2 was exponential with an annual increase rate of 13% (CI = 5.6%–18.1%). While this value is above the species’ estimated maximum plausible growth rate of 11.8%, it is reasonably close to previous reports of between 10–12%. The coefficient of variation, however, was too large for a reliable trend estimate. Perception bias was also not accounted for in these calculations. Based on a crude appraisal which yielded an estimated p(0) of 0.783 (from independent observer effort, CV = 0.973), the 2008 humpback population size may be as large as 33,300. In conclusion, the work here provides evidence of an increasing Breeding Stock D population, but further surveys are necessary to confirm whether the population is indeed increasing at its maximum rate.
CLASSICAL AND NEW ASPECTS IN DEGRADATION OF AROMATIC XENOBIOTICS
Authors: Vasileva Evgenia , Parvanova-Mancheva Tsvetomila , Beschkov Venko
Published: April 2019

Organic chemical mixtures are prevalent in waste waters from industrial and municipal sources as well as in contaminated groundwater. Phenols are pollutants found in wastewaters from oil refineries, chemical plants, explosives, resins and coke manufacture, coal conversion, pesticide and textile industries. The main contaminants of refinery wastewater include phenols, polycyclic aromatic hydrocarbons (PAHs) as well as heavy metals. Among these toxic pollutants, phenols are considered to be the most hazardous ones, and they are certainly the most difficult to remove. Phenolic compounds are toxic at relatively low concentration. Because of these low concentrations the most suitable methods for their removal are the microbial ones. The present work is a review of biodegradation of phenol. Degradation of phenol occurs as a result of the activity of a large number of microorganisms including bacteria, fungi and actinomycetes. There are reports on ma33ny microorganisms capable of degrading phenol through the action of variety of enzymes. These enzymes may include oxygenases, hydroxylases, peroxidases, tyrosinases, oxidases etc. Batch experiments were carried out in a different bioreactors. Biodegradation of organic chemicals by microbes using pure cultures can produce toxic intermediates. This problem may be overcome by the use of mixed cultures that have a wider spectrum of metabolite degradation properties.
In this revew we described also some new technology for biodegradation of phenol like: different immobilization, FISH (Fluorescence in-situ hybridization) analysis, nanobiotechnologies and etc.
Key words: phenol, biodegradation, microorganisms, enzymes, immobilization, FISH analysis, nanobiotechnologies

Published: April 2019

The present work is an account of an ongoing work on biogas production from animal wastes at LEREA (Laboratoire d’enseignement et de recherche en énergétique appliquée) in Mamou, Guinea. The work consists of biogas production from anaerobic digestion and co-digestion of cow dung and droppings. We focus in this report on the determination of the physico-chemical characteristics of the experimental setup. We have carried out three experiments of anaerobic digestion each one lasting 45 days at mesophilic temperature (temperature was maintained in the range 27°C - 28°C). Biogas - 28.4 liters have been obtained from droppings, 22.6 liters from cow dung and 38.7 liters from co-digestion of the previous two wastes. The following physico-chemical characteristcs were observed for cow dung: humidity 43%, dry matter 20.83%, organic matter 57%, density 625kg/m3, carbon content 31%, nitrogen content 1.46%, nitrogen-carbon ratio 21/30. For droppings we measured: humidity 35%, dry matter 65%, organic matter 62%, density 250 kg/m3, carbon content 36%, nitrogen level 1.83%. This characterization was carried out on a sample of 3 g of each type of substrate. These results agree with those of the literature that we were able to compare with.

Redshifts and the hypothesis of variable particle masses
Authors: Narlikar Jayant V.
Published: April 2019

There are ideas in literature which seek to understand particle masses at a more fundamental level [1-3]. Mach's principle has been one of the motivators of such efforts. This talk will highlight a new way of looking at the conventional cosmological redshifts. It has its origin in the Hoyle-Narlikar theory of conformal gravity in which particle masses arise from other particles in a Machian fashion [4]. It will be argued that instead of an expanding universe, one may talk of a static Minkowski universe in which masses of elementary particles vary with epoch. All the features of the standard cosmology can be understood this way. Additionally it will be shown that delayed matter creation can lead to the so-called anomalous redshifts found by Arp and others [13,14]. The underlying theory for this phenomenon was proposed as the ‘Variable Mass Hypothesis’ by the author [8]. This theory will be described and its further development briefly discussed.
Digital outline of elementary particles via a root space diagram approach
Authors: Trell Erik
Published: April 2019

In the immediate intuitive as well as penetrating logical contemplation, the universe stands forth as an ever-present entity; consisting solely of itself, and fulfilling solely itself. A truism and a truth, and also a conclusion by proxy because its shape expressions are covered by curvilinear mathematical functions which completely exhaust their solution spaces, displacing any ‘parallel’ universes to isolates of less perfection since the fundamental formative categories of straight and round are thereby already consummated by our version. My first impression, under the northern light upon the velvet screen in starry polar nights of childhood Lapland, still holds, then, of the shining moon continuously swirling along with me and everything else from our preceding moment into our next, with the advancing now-slice flanked by the blackened archive of used and pending slices always restoring precisely enough room for the whole past and future at the one and same time. This vision and its lingering question may here be resolved by a facts and findings-based scientific testing which I feel is facilitated by my meantime experience as a rational researcher in a related field of descriptive natural history as well as by another archetypal arctic apprehension hard to miss when witnessing the instant change of water to ice from hence isotropically dispersed origins at once inflated over the entire surface of a freezing lake: it is a phase transition, where one uniform element alone is simultaneously spanned into an alternative principal form of space-filling alignment and where dynamics flares up in that timeless quantum fluctuation. Like the partial derivatives of differential equations the irreducible unit in question is the infinitesimal straight line undergoing the classical three-dimensional Euclidean space Lie algebra transformation of its orientation “between the Plücker line geometry and a geometry whose elements are the space's spheres”. Coming back later to the ontology and prescribed machinery of this, the fully and easily reproducible outcome comprises the complete observed elementary particle spectroscopy with detailed mass numbers, charge levels and angular momentums organized in a continuously space-filling polyhedral space frame lattice architecture that over sequential levels of self-expansion meets up with presently disclosed nanotechnological structures so as to directly making up matter in a binary digital mode which is essentially that of dialectics and logic, too, consorting the Cartesian cut between concrete and abstract; matter and mind; structure and language from the very start. As actual realization as well as computational method, the only, and prior, and equally definite and uncircumventable parallel is professor Santilli's revolutionary iso-. geno- and hypermathematics, whereas for structure the only parallel to straight is-straight, leaving scant latitude at least for a simpler workable universe.
Optimal control on nonholonomic black holes

This paper studies a nonholonomic black hole system as kernel of a Gibbs-Pfaff form or by the span of four appropriate vector fields. Joining techniques from Riemannian geometry, optimal control and thermodynamics, we create a new geometrical model for black holes systems that produce meaningful results. We give the solution of a two-time optimal control problem describing the torsion of a nonholonomic black hole, taken as parameters of evolution the entropy and the angular momentum. Also we prove that the nonholonomic black holes systems can be controlled by uni-temporal or bi-temporal bang-bang controls.

Ripple effect in object oriented programs
Authors: Mansour Nashat , Salem Hani
Published: April 2019

Upon introducing a local change in a method or a class in an object oriented program, the ripple effect gives a measure of the amount by which this change may affect other methods/classes. That is, the ripple effect shows maintainers the ramifications of any change they may make before that change is actually implemented. In this paper, we propose techniques for measuring the ripple effect in object oriented programs and use it to compute an indicator of logical stability. First, we investigate object oriented dependences and illustrate how these dependences and some metrics can be used to determine change impact and propagation. Then, we use matrix arithmetic techniques for computing the ripple effect in object oriented programs and show their application at the intra-class, inter-class and architectural levels.

Within the context of OO, there are a lot of interactions among different objects that result in many communication activities. Besides the feed-forward communication activities, many bypassing activities are generated in the pipeline structure.

In this paper, we present a performance model that analyzes and evaluates the execution and communication times of OO software that runs on pipeline architecture. The model realizes both the feed-forward and the bypassing communication. We utilize the model to restructure the target software to achieve better performance. The restructuring algorithm has two phases; the first phase is concerned with maximizing the throughput. The second phase aims to minimize the latency and fully exploit the system resources.

Recently an efficient clustering protocol has been reported [1] for mobile ad-hoc networks (MANET). The proposed clustered network has been shown to be more stable than the clustered networks as reported in [3,4]. In this paper, we have proposed a distance vector based multicast routing protocol for MANETs that are clustered following the idea of [1]. The proposed scheme needs much less amount of information exchange compared to the distance vector routing scheme designed for unclustered network. Because of significant reduction in distance vector routing table size and its adaptable nature to the changing ad-hoc network topology caused by node mobility this proposed multicasting routing protocol has been shown to offer efficient utilization of both limited memory and bandwidth for MANET. Besides, we have also shown how our clustered network can offer efficient resource utilization when CBT routing strategy is used.
De Icaza a Arcos: el puente de intertextualidades que atravesó Andrés Chiliquinga
Authors: Avalos Flórez Edison Duván
Published: April 2019

Este texto identifica, analiza y evalúa, desde el enfoque teórico de Gérard Genette, las relaciones intertextuales presentes en las novelas Memorias de Andrés Chiliquinga, de Carlos Arcos Cabrera (2013), y Huasipungo, de Jorge Icaza (1934). Su objetivo es  proponer algunas ideas respecto a los procesos de creación y de lectura de ambas obras, especialmente de la obra de Arcos. Entre otras cosas, señala el modo como Arcos, en su novela, le otorga nuevos significados a los sentidos que no fueron resueltos por Icaza en Huasipungo.
Los desempeños de comprensión en estudiantes de tercero de bachillerato de la unidades educativas fiscales de la ciudad de Tulcán
Authors: Enríquez Vizcaino Justo Pastor
Published: April 2019

Los desempeños de comprensión de alumnos de educación secundaria constituyen el objeto de estudio de diversas investigaciones, ya que el futuro de los nuevos profesionales del Ecuador está enmarcado en procesos educativos que despliegan las Instituciones Educativas especialmente las de nivel secundario. La presente investigación pretende determinar los desempeños de comprensión de estudiantes de Tercero de Bachillerato General Unificado de las Unidades Educativas Fiscales de la ciudad de Tulcán, basado en dos aspectos: niveles de comprensión de los escolares y el accionar académico de los docentes. En la presente investigación se aplicó una encuesta a los educandos, que hace referencia actividades con diversa demanda cognitiva, obteniendo como resultado que   la mayoría (85,61%) evidencian un nivel de comprensión ingenua, seguido por el de principiante, luego de aprendiz y por último de maestría. También se aplicó una encuesta a maestros de las cuatro áreas fundamentales y entrevista a vicerrectores, ambas técnicas tienen el mismo enfoque, en las que se tomaron algunos indicadores como referentes investigativos, dando como resultados notables, que la labor docente limita la mejora de los desempeños de comprensión, ya que los discentes en el proceso educativo, no se desenvuelven con flexibilidad, no presentan la información de nueva manera, los conocimientos no responden al contexto y a solución de problemas reales, las tareas no promueven investigación y no se vincula con otras disciplinas, no realizan proyectos de investigación y se da mayor énfasis a la evaluación sumativa. Finalmente se plantea un nuevo direccionamiento de lineamientos curriculares.

Estados Unidos es uno de los principales socios económicos de Ecuador, ya que su mercado es el destino de la mayor parte de exportaciones petroleras. A lo largo de la historia, Ecuador ha intentado fomentar las exportaciones para tener una balanza comercial positiva a través de distintas políticas comerciales. En el presente artículo se hace un análisis de la evolución de la política comercial del país y su impacto en las importaciones y exportaciones con Estados Unidos. Además, se determina los nuevos escenarios de cómo las nuevas políticas de los dos países influirán en la evolución de las relaciones comerciales y los potenciales productos a exportarse.

Con el objetivo de evaluar la agrobiodiversidad existente en tres fincas en la parroquia de Peñaherra, Cotacachi, se realizó un inventario de las especies y variedades vegetales que tienen algún uso conocido dentro del agroecosistema; de esa forma se identificaron 97 especies. La riqueza de especies por finca fue de 46, 30 y 65, mientras que el índice de diversidad de Margalef arrojó que la finca 3 tiene una diversidad superior a 5, lo que se considera alta, mientras que la finca 2 cuenta con una diversidad media. En este estudio se empleó por primera vez en Ecuador el índice de Agrobiodiversidad (IDA), para lo cual la diversidad de la finca fue clasificada en cuatro grupos (alimentación humana, alimentación animal, alimentación del suelo y diversidad complementaria) y se les asignó un valor teniendo en cuenta la importancia dentro del ecosistema, al realizar el cálculo, se obtuvo que la finca 3 es la de mayor IDA, aunque no llega a los valores adecuados descritos en la literatura; es por ello que los agricultores deben tomar en cuenta los subíndices calculados para que incluyan en su finca plantas que eleven los subíndices deficientes, solo así se podrá llegar a un agroecosistema sostenible.

Se busca establecer con esta investigación el grado de aplicabilidad en torno al manejo de los procesos en la parte productiva y comercial en las empresas florícolas del cantón Pedro Moncayo (Tabacundo), el concepto de mapa de procesos lo determinan como una representación gráfica de los procesos que están presentes en una organización, mostrando la relación entre ellos y sus relaciones con el exterior (AITECO CONSULTORES, 2016), de lo cual se estableció según la investigación que un número considerable de empresas florícolas no hacen levantamiento de procesos, siendo sus principales procesos críticos las áreas de poscosecha y gestión comercial sin diseños de flujos de procesos con líneas de tiempos, viéndose afectados en sus costos y entregas Justo a tiempo (Just Time). Por lo tanto es necesaria la aplicación inmediata de un mapa de procesos, levantamiento de procesos, identificación de procesos críticos y diseño de flujos de procesos con limitaciones de tiempos.
Optimized Fuzzy Cmeans – Fuzzy Covariance – Fuzzy Maximum Likelihood Estimation Clustering Method Based on Deferential Evolutionary Optimization Algorithm for Identification of Rock Mass Discontinuities Sets
Authors: Esmaeilzadeh Akbar , Shahriar Kourosh
Published: April 2019

Detecting of joint sets (clusters) is one of the most important processes in determining properties of fractures. Joints clustering and consequently, determination of the mean value representing each cluster is applicable to most rock mass studies. It is clear that the accuracy of the clustering process plays a key role in analyzing stability of infrastructures such as dams and tunnels and so on. Hence, in this paper, by reviewing several methods proposed for clustering fractures and considering their advantages and disadvantages, a three-stage hybrid method is developed which contains Fuzzy c-means, Fuzzy covariance and Fuzzy maximum likelihood estimation that by utilizing the modified orientation matrix had been optimized. This method is optimized by the Differential Evolutionary algorithm using a new and strong cost function which is defined as the computation core. In addition, using three clustering quality comparing criteria, the new developed method of differential evolutionary optimized of fuzzy cmeans - fuzzy covariance - fuzzy maximum likelihood estimation clustering method (DEF3) is compared with other base and common methods using field data. After doing the calculations, the developed method by giving the best values for all the criteria provided the best results and good stability in meeting different criteria. The DEF3 method was validated using actual field data which mapped in Rudbar Lorestan dam site. The results revealed that DEF3 acquired the best rank among the other method by getting the value of 0.5721 of Davis-Bouldin criterion, 1403.1 of Calinski-Harabasz criterion, and 0.83482 of Silihotte as comparing criteria of clustering methods.

In today’s competitive market providing products only in low cost and high quality is not enough.  Environmental concern in manufacturing is also an important issue now. To attract investors and customers organizations need to practice environmental manufacturing. This study is focused to present the relationships between some specific environmental manufacturing practices and their relative specific competitive outcomes in the important and vast industry of garment’s knitting sector in Bangladesh. Although there are several studies on the impact of environmental practices on the organizations outcomes but they are less construable due to many limitations. This study explores the environmental manufacturing practices under two categories pollution prevention and product stewardship and shows their relative competitive outcomes and establishes the relation between them. Based on the surveys and research it is found that some competitive outcomes are positively affected by some of the practices. These findings are believed to motivate the companies to turn towards the green manufacturing.
