An Improved Partitioned Clustering Technique for Identifying Optimum Number of Dissimilar Groups in Multimedia Dataset

Sreedhar Kumar S and Madheswaran M
Abstract:
This paper presents an improved partitioned clustering technique called Optimum N-Means (ONM), aims to robotically identify finest number of dissimilar groups in a large multimedia (gray scale image) dataset based on distinct number of centroid objects for deeper data elements enrichment without predetermined number of clusters. It involves two stages, in the first stage, a method Search Distinct Centroid Objects (SDCO) is introduced and it inevitably identifies optimum number of centroid objects in the input image dataset based on rate of object repetition in the image dataset. After, it divides the image dataset into appropriate number of unrelated clusters based on distinct centroid objects which is obtained by SDCO stage and finally it follows to validate the clustering result by cluster validation scheme. Experimental results show that the ONM technique is better and efficient for inevitably identifying the optimum number of dissimilar clusters over the grey scale image with higher intra thickness and lesser intra separation compared to existing K-Means technique.

Touré Awa, Konan Akissi Germaine, Kouakou Nanan Joseph and Ipou Ipou Joseph
Abstract:
Dans les systèmes agricoles, hormis les contraintes liées aux conditions socio-économiques, aux facteurs biotiques (maladies et ravageurs) et abiotiques, les contraintes dues aux adventices entrainent d’énormes pertes de productions agricoles. Pour accompagner de manière efficiente les agriculteurs vers des systèmes et des pratiques de gestion durable des mauvaises herbes, il faut d’abord connaître leurs techniques dans la maîtrise de ces plantes avant de proposer des innovations. L’objectif de cette étude a été de mettre en relief les pratiques paysannes actuelles dans la gestion de l’enherbement du manioc dans le département de Toumodi au Centre de la Côte d’Ivoire. A l’aide d’un questionnaire, 130 producteurs de manioc ont été interrogés. Des relevés floristiques ont été également effectués par la méthode du tour de champ. Dans cette localité, les itinéraires techniques de désherbage sont encore traditionnels. Quarante-et-cinq pourcent (45p.c.) des producteurs de manioc dans le département de Toumodi pratiquent le défrichement manuel, 78,85p.c. labourent manuellement et tous désherbent manuellement avec comme outil la machette ou la daba. Seulement 3p.c. pratiquent le défrichement chimique, 1p.c., le défrichement mécanique, 19,23p.c. pratiquent le labour motorisé et 1,92p.c. ne pas font de labour.
Keywords: Mauvaises herbes, Méthodes de désherbage, Culture de manioc, Département de Toumodi, Côte d’Ivoire.

Ismail S Iriqat
Abstract:
The purpose of the study is evaluating the effectiveness of applying Transformational leadership within the role of administrative leaders in Palestinian universities as perceived by beneficiaries such as faculty members in Beirzait University and Al-quds University, to spread awareness and increasing faculty members' knowledge of transformational leadership traits as it contributes in instilling excellence principles in the institutional work through applying the domains of transformational leadership, consequently; exploring similarities and differences between them.
The sample contained two groups, the first was faculty members from Beirzait university totaling (100) faculty members as they are the most important beneficiaries and able to determine the application of Transformational leadership within the role of administrative leaders in Palestinian universities, the second was a group of faculty members from Al-quds university totaling (100) faculty members.
In general, the findings related to individual consideration showed that there were no differences in the opinions of both universities about the application of Transformational leadership within the role of administrative leaders in Palestinian universities except for the second item provided that (the administrative leadership in the university cares about the feelings of employees through encouragement and advise) in favor of faculty members in Beirzait universities. Moreover, item 970 provided that (administrative leadership spends time in training others), item (10) provided that (administrative leadership works on training and developing the abilities of employees in favor of Beirzait university; this indicates the decrease in job satisfaction of Al-quds university faculty members especially in training and development; this goes with inspiration domain for item (3) related to the inspiring of employees by the administrative leadership and intellectual simulation domain for item (60 related to the determination of weakness and strength points by administrative leadership to treat them, this indicates the accuracy and agreement of respondents answers.
Therefore, the findings of the study showed that the administrative leadership in al-quds University should listen to its employees and take careful attention to their needs and goes over its personal interests to the interests of the group. Moreover, the determination of weakness and strength points by administrative leadership to treat them through adopting evaluation and positive enforcement strategy.

Study of Effects of Elliptic Plates and Comparison with Other Lubrication Models Using Incompressible Second-Order Fluid

Sundarammal Kesavan and Nisha
Abstract:
A near investigation of non-Newtonian consequences for different parallel plates contrasted with endlessly/infinite long rectangular, circular, elliptical, equilateral triangular plates lubricated by incompressible second order fluids on the performance characteristics by squeeze film bearing are displayed. This model is the least difficult sort of model which accurately represent where the oil is subjected to quickly changing conditions along its streaming way, such time reliance is the second order fluid. The fundamental lubricant equations are found from the original conditions. It is discovered that as in Newtonian liquids, squeeze is continuously quicker as we go from rectangular plates to equilateral triangular plates and the span required declines as the second-order parameter increments.

Abstract:
Geographic Information Science is applied in the domain of Hydrology and Hydrogeology to address geology-related environmental problems, reflecting the wide scope, societal, educational and human implications of the cross-cutting nature of water scarcity in such a geological context. This study focuses on the class analysis of various parameters influencing aquifer recharge in a crystalline basement medium. Those parameters are slope, drainage density, fracturing density and permeability (hydraulic conductivity). The results using Landsat 8 and SRTM images ground resistivities and boreholes dataset show that, areas with slope less than 12° are favorable for infiltration of water. For the drainage density, areas with values less than 0.246 km/km2 are favorable for recharging of the aquifer. Regions where the hydraulic conductivity ranges between 17.1 and 61.00 m/day are also favorable for infiltration. The map of fracturing density shows that localities with values greater than 2.3 km/km2 are favorable for charging of the aquifers.

Imane EL Adnani, Abdelkader Younsi, Khalid Ibno Namr, Abderrahim El Achheb and El Mehdi Irzan
Abstract:
Research on groundwater quality and usage in the Cenomanian aquifer in a near-coastal agricultural region in Morocco was conducted in 2005 and in 2016. This study was undertaken to determine the characteristics of water quality in this aquifer in order to identify the sectors most affected by different types of pollution due mainly to the increase in human activities in this region.
Forty-six wells in the vicinity of the landfill site were sampled and analyzed for parameters including: temperature, electrical conductivity, pH, chloride, sulphate, nitrate, sodium, potassium, calcium, magnesium and bicarbonate, in addition to the depth of the water table. The concentrations of most of the chemical elements exceed drinking water standards such as chloride, sodium, nitrate and sulphate (4535, 2411, 264 and 851 mg/l respectively); these wells are located either near the Moulay Abdellah landfill or in the agricultural and coastal areas.
The analysis of the overall quality of the water revealed that just 20 % of the monitored wells are of good quality, with the quality of the rest ranging from medium to very bad quality. Poor water quality in the Cenomanian aquifer is associated with lithological, marine and anthropogenic sources of chemical constituents.

Dismissal of People in Junior Enterprise: Relation Between Expectactions and Reality

Esther Azevedo Reis and Max Leandro de Araújo Brito
Abstract:
Junior enterprises are organizations in the universities that are formed by students and have as goals provide business experience and apply knowledge acquired. The turnover and the dismissals in these companies will be presented together with their causes, for example, employee satisfaction, the presence of other extracurricular activities and the failure to meet the expectations of the members. Thus, the work aims to analyze the people’s dismissal in the junior enterprise of the Universidade Federal de Itajubá (Unifei) – campus Itabira from the comparison between the member’s expectation according to the organization when he enters and the reality lived during the permanency. The research was based on qualitative evidences with the data collection through interviews and the exam consisted in content analysis that provided the information’s understand that was obtained in the interviews. It was found that the students mostly expect from the junior enterprise consulting in their specific areas of graduation, training, leaders and mentors and report that the company demands a lot of time that makes difficult to reconcile with the universities’ activities. Thus, the junior enterprise must analyze the expectations when the members join the company to determine ways to meet them and, consequently, reduce the voluntary dismissals.

Unfair Inequalities in Health Care: A Critical Appraisal Under A Multifarious Approach

Estela Barbosa Capelas, Antônio Pires Barbosa, Márcia Mello Costa De Liberal and Chennyfer Dobbins Abi Rached
Abstract:
Many factors can influence inequalities in health care, for example, its unequal opportunities in education or employment. It is believed the social determinants of health are causal factors for which inequalities are unjust. Measuring causal variables in this context requires measuring unfair inequalities in four distinct categories, namely: legitimate effort, legitimate circumstance, illegitimate effort, and illegitimate circumstance. Lifestyle is a classic example of inequality as a legitimate circumstance because people have the chance to choose. Evaluating measures as well as unjust inequality measures in health and care delivery are necessary because the distribution of the variables may reflect fairness. Therefore, the aim of this study is to reflect on the methods of measuring inequality in health care. It is an analysis of these methods as the presence of unjust inequalities are no longer exclusivity of the so-called Third World or Developing Countries. We conclude that there are various methods of analyzing unfair inequalities in health and health care, but the method of multifarious analysis is more appropriate to allow different ethical positions.
