A Framework to Enhance Security in Nemo Environment Using AAA Mechanisms
Authors: J Isac Gnanaraj , . Sriram
Published: June 2018

One of emerging trends in the mobile network era is Network Mobility (NEMO). It was standardized by the Internet Engineering Task Force (IETF) and gained attention of the researchers because of research opportunities that it provides. Though it was developed based on MIPv6, there are few spots that must be analyzed and rectified, especially in the security aspects. According to the literatures, NEMO lacks in providing a robust Authentication, Authorization and Accounting (AAA) services to its users. AAA operations must be performed for all the players of the mobile network, because a hacker may reside at any place and try to access the mobile network by hiding behind valid or genuine nodes’ addresses. This research work aims to provide an AAA framework for NEMO by comprising three different mechanisms which are developed for Local Mobile Node (LMN), Visiting Mobile Node (VMN) and Mobile Router (MR). Simulation and performance analysis are done.

Authors: Panda Dhyanadipta
Published: June 2018

Women are considered as goddess in Indian culture. But till today in every sphere of life women have been humiliated like anything in the society. In India many rules and legislation has been made for women since independence but till today a woman is fighting for her fundamental right. Women empowerment is the only way by which it can be possible to give equal status to women in a male dominated society like India. To be empowered, women should come forward and realize that they are not second grade citizen of the society and at the same time also equally capable with men in all aspect of livelihood. In this context, the present study analyses different issues of women empowerment and reasons behind not successful implementation of women empowerment programs in the country.  Education, financial independence, equal recognition in work place, change of mind set among men can help to accelerate the process of women empowerment in India.

Published: June 2018

The project deals with an attempt of developing an advanced atomizer concept to control the spray formation for mixed spray combustion is examined. The aim is to improve the spray structure that preserves the flame height and modifies the width of the flame. The atomizer concept for development of a modified spray combines a swirling liquid film generation that is atomized by an external swirling gas flow. To investigate the main characteristics of the combined atomizer, experiments and numerical simulations of the flow operation with different geometric nozzle parameters (number of gas holes) and process parameters (flow rate of fuel and air ) as well as fuel properties are carried out to produce a modified, enlarged and steady spray of small droplets. In this work, fuel (kerosene) is used as the liquid phase and air as the gas phase. In the simulations, the multiphase flow is modelled using k-epsilon model with transient flow and the turbulence of the gas phase is 10% and fluid is used as dispersed medium and gas as constant fluid at Standard Temperature and Pressure (STP). The goal of the numerical simulations is to investigate the cone angle and flow behaviour of the fuel injector, impingement of surrounding air on the fuel is noticed and the morphology of the spray is examined and the fuel injector is made as prototype design and fabrication work is carried and tested in the laboratory and compared with the CFD analysis..

This situation can escalate during the times of disaster events due to their cascading effects damaging the water storage and supply network infrastructure. Under this study, integrated water management has been emphasized as a comprehensive approach to address the crisis during extreme events. The process of integrated water management is described not only from water management perspective but also from perspectives of disaster management and Sustainable Development Goals. Emphasis on technological and institutional reforms for efficient and effective implementation during disaster event has been given. Along with this, the role of community participation is also considered as an integral component to make the proposed integrated approach sustainable. Results of an impact assessment study on human lives, economic and environmental conditions can be used to create holistic response plans which subsequently may result in disaster risk reduction and thus increased resilience towards vulnerability in disaster scenarios.
Non-Linear Analysis of Cable Stayed Bridges
Authors: Ahmed Zuber , Ahmed Esar
Published: June 2018

The concept of cable-stayed bridges dates back to the seventeenth century. Due to their aesthetic appearance, efficient utilization of material, and availability of new construction technologies, cable-stayed bridges have gained much popularity in the last few decades. After successful construction of the Sutong Bridge, a number of bridges of this type have been proposed and are under construction, which calls for extensive research work in this field. Nowadays, very long span cable-stayed bridges are being built and the ambition is to further increase the span length using shallower and slender girders. In order to achieve this, accurate procedures need to be developed which can lead to a thorough understanding and a realistic prediction of the bridge’s structural response under different load conditions.In the present study, an attempt has been made to analyze the seismic response of cable stayed bridges with single pylon and two equal side spans. This study has made an effort to analyze the effect of both static and dynamic loadings on cable-stayed bridges and corresponding response of the bridge with variations in span length, pylon height and pylon shape. Comparison of static analysis results have been made for different configuration of bridges - their mode shapes, time period, frequency, pylon top deflection, maximum deck deflection; and longitudinal reaction, lateral reaction and longitudinal moment at pylon bottom. Time history analysis results have been investigated for different configuration of bridges under the effects of three earthquakes response spectrum (Bhuj, El Centro and Uttarkashi) - axial forces in stay cables, deck deflections and stress diagrams at maximum peak ground acceleration of the above mentioned earthquakes.

It is vital to maintain the efficacy of this data the need of data recovery services is highly essential. Cloud computing is anticipated as the vital foundation for the creation of IT enterprise and it is an impeccable solution to move databases and application software to big data centers where managing data and services is not completely reliable. Our focus will be on the cloud data storage security which is a vital feature when it comes to giving quality service. It should also be noted that cloud environment comprises of extremely dynamic and heterogeneous environment and because of high scale physical data and resources, the failure of data centre nodes is completely normal.Therefore, cloud environment needs effective adaptive management of data replication to handle the indispensable characteristic of the cloud environment. Disaster recovery using cloud resources is an attractive approach and data replication strategy which attentively helps to choose the data files for replication and the strategy proposed tells dynamically about the number of replicas and effective data nodes for replication. Thus, the objective of future algorithm is useful to help users together the information from a remote location where network connectivity is absent and secondly to recover files in case it gets deleted or wrecked because of any reason. Even, time oriented problems are getting resolved so in less time recovery process is executed.

Authors: Saleh Muhammad , Imansyah Fitri , Gani Usman A. , . Hardiansyah
Published: June 2018

This paper proposes a novel and efficient hybrid algorithm based on combining particle swarm optimization (PSO) and gravitational search algorithm (GSA) techniques, called PSO-GSA. The core of this algorithm is to combine the ability of social thinking in PSO with the local search capability of GSA. Many practical constraints of generators, such as power loss, ramp rate limits, prohibited operating zones and valve point effect, are considered. The new algorithm is implemented to solve combined environmental economic dispatch (CEED) problem in power systems considering the power limits. The CEED is to minimize both the operating fuel cost and emission level simultaneously while satisfying the load demand and operational constraints. The effectiveness of the proposed algorithm has been tested on 10-unit system and the results were compared with other methods reported in recent literature. The simulation results show that the proposed algorithm outperforms previous optimization methods.

Authors: Khan Irum , Kasliwal Neeti , Joshi Mahesh Chandra
Published: June 2018

Over the past decades, concern about the environment has become not only a significant public issue but also a crucial topic in academic research. A sharp rise in environmentalism has emerged. Despite an increase in consumer expectations for business to do more for society than deliver on economic conditions and many firms' increasingly adopting socially-responsible stances, marketplace behaviour highlights a gap between what consumers report they expect from firms and what they are prepared to reward. This paper discusses the review of past papers to identify the gaps and to frame a conceptual model as per the consumer and firm’s expectation from CSR policies.

Authors: Jeyan J. V. Muruga Lal , Rupesh Akhila , Lal Jency
Published: June 2018

The aerodynamic module combines the three-dimensional nonlinear lifting surface theory approach, which provides the effective propagated incident velocity and angle of attack at the blade section separately, and a two-dimensional panel method for steady axisymmetric and non-symmetric flow has to be involved to obtain the 3D pressure and velocity distribution on the wind mill model blade. Wind mill and turbines have become an economically competitive form of efficiency and renewable work generation. In the abroad analytical studies, the wind turbine blades to be the target of technological improvements by the use of highly possible systematic , aerodynamic and design, material analysis, fabrication and testing. Wind energy is a peculiar form of reduced form of density source of power. To make wind power feasible, it is important to optimize the efficiency of converting wind energy into productivity source. Among the different aspects involved, rotor aerodynamics is a key determinant for achieving this goal. There is a tradeoff between thin airfoil and structural efficiency. Both of which have a strong impact on the cost of work generated. Hence the design and analysis process for optimum design requires determining the load factor, pressure and velocity impact and optimum thickness distribution by finding the effect of blade shape by varying thickness on the basis of both the aerodynamic output and the structural weight.

Neo-industrialization models and industrial culture of small towns
Authors: Pipan Tomaž
Published: June 2018

In the last 30 years the global supply chains and containerization transformed the world of production and stretched it across the globe. With the exodus of Process and Assembly (P&A) segment of industrial production from the developed countries, the “global north” not only lost the production capacity itself, but more importantly, the know-how in making that is a basis of industrial culture.

The neoliberal attitudes in industrial production were the main force behind slow but persistent abandonment of the automotive industry in Detroit, or closing down of the coal and iron industry in the Ruhr region in Germany. Contemporary urban renewal strategies of industrial areas rely on injection of tourism based on design, popular art, cultural and leisure activities, like the Emscher Landschaftspark in Ruhr region, Germany. However, tourism-based redevelopment is economically questionable in small industrial towns. For such areas we need to envision alternative agencies that industrial past and industrial production can offer. One of the most underrated aspects of industrial production is the know-how imbedded in the P&A segment of industrial process. We argue for the industrial production know-how as a relevant part of the new innovation economy of small towns and of the local culture. This paper will trace the capacity of industrial production for culture-making by referring to production-innovation models described in regional geography. Firstly the paper identifies the P&A know-how worth reshoring. Secondly, it describes two models of neo-industrialization in order to thirdly identify a new hybrid type of a regional model and its culture.

Institutionalization of the development management system in Poland
Authors: Sługocki Waldemar
Published: June 2018

Institutionalization of the development management system in Poland The Polish development policy was shaped along with the process of political transformation and integration with the European Union. After 1990, the management of development policy had a provisional character, in fact the system did not exist. At the national level, there was certain lack of the legal framework, strategic documents, institutional framework and financing. The progressively progressing process of European integration, the transfer of pre-accession funds and the prospect of EU membership and also the possibility of implementing cohesion policy have enabled the adoption of solutions appropriate for many EU Member States. In the first phase, in 1998, exactly on 5 June, the law on voivodship and poviat level self-government was adopted. The following year, the act on departments was adopted, on the basis of which the office of the minister competent for development was established, and in 2000 the fundamental act of law was adopted, namely the act on the principles of supporting regional development. Along with the possibility of cohesion policy implementation, a strategic planning system was adopted, primarily for the purpose of taking advantage of the European funds, and the corresponding institutional set-up was created. However, it was only in 2008, at the initiative of the Strategic Advisory Group at the Prime Minister, that the solutions at that time were reviewed and changes were recommended in the area of strategic management of Poland’s development. The justification for the changes was the need to have a new “compass of development”, which after the period of implementation of accession goals and short-term needs characteristic of societies in the transformation phase prevented the so-called “development drift” situation, that is, stable growth, but too weak to compare to the most developed Western countries. After the adoption of the document “Assumptions of the development management system of Poland” by the Council of Ministers on 27 April 2009 and as a result of further work, a national development management system was developed.

Authors: Gorączkowska Jadwiga
Published: June 2018

The impact of business support organizations on the innovative activity of Lubusz industrial enterprises Business support institutions are one of the institutional solutions that are aimed at stimulating innovation, and influenced by innovation policy. The aim of the article was to determine the impact of business support institutions on the innovative activity of enterprises that use their services in comparison to entities that do not. However, the research hypothesis was that institutions will increase the chances of running innovation activity and cooperation, but the impact will be diversified. 756 industrial enterprises from the Lubusz voivodeship took part in the survey. It was carried out in 2014 for the years of 2011-2013. The multifactorial logit modelling was used as the research model. As a result of the conducted analyses, it was established that technology parks and training and consulting centres are a strong link of supporting the innovation of industrial enterprises in the region. In addition, innovation centres, such as technology parks, technology incubators, technology transfer centres and business angel networks increase the chances of incurring expenditures on research and development activities. In the voivodeship, the institutions also initiate cooperation in the area of new solutions. Entrepreneurs are more likely to cooperate with each other than to transfer knowledge from the sphere of science to business.

Life Cycle Assessment (LCA) in Environmental Impact Assessment (EIA): principles and practical implications for industrial projects This article discusses the theoretical and practical aspects of the application of the life cycle assessment (LCA) technique in the environmental impact assessment (EIA) process. LCA enables to consider the environmental impacts of the whole production system, including upstream and downstream processes and to estimate their consequences already at the project planning stage. It was illustrated using the case study of the planned furniture production plant representing the industrial sector. The conventional simplified cradle-to-gate LCA analysis, using SimaPro software and the ReCiPe Endpoint method, was performed. It revealed that unlike the findings of EIA made with the support of traditional methods, not waste, airborne emissions and noise, but the particleboard and the fibreboard used by the planned furniture production plant have the most detrimental impact on the environment in all impact categories. The greatest damage it causes in the areas of protection of resources followed by ecosystems. The research proved high applicability of EIALCA approach for the evaluation of the environmental impacts of planned industrial projects.

Published: June 2018

The study assessed the relationship between social capital and contraceptive use among rural dwellers in Akwa Ibom State, Nigeria. Data obtained from one hundred and sixty rural dwellers, using multi-stage sampling procedure, were analyzed using descriptive statistics. Results show that 51.3% of the respondents, with an average age of 40 years, were females and 71.3% were married. Majority of the respondents (96.2%) had formal education with an average monthly income of N28,900.50. Results also reveal that a high level of social capital exists among 56.9% of the respondents; and that the most utilized contraceptive methods by the rural dwellers were barrier methods, hormonal contraceptives and abstinence. A simple linear regression shows that social capital positively influences contraceptive use by rural dwellers in the study area. Hence, social capital should be taken cognizance of by policy makers in the study area when formulating policies aimed at controlling the rural populace via contraceptive use.
The sensitivity of contact stresses in the mandibular premolar region to the shape of Zirconia dental implant: A 3D finite element study
Authors: Velmurugan Duraisamy , Alphin Masilamany Santha , Tony Benedict Jain AR
Published: June 2018

Background: Implant thread profile plays a vital role in magnitude and distribution of contact stresses at the implant-bone interface. The main goal of this study was to evaluate the biomechanical effects of four distinct thread profiles of a dental implant in the mandibular premolar region.

Methods: The dental implant represented the biocompatible Zirconia material and the bone block was modelled as transversely isotropic and elastic material. Three-dimensional finite element simulations were conducted for four distinct thread profiles of a dental implant at 50%, 75%, and 100% osseointegration. An axial static load of 500 N was applied on the abutment surface to estimate the stresses acting within the bones surrounding the implant.

Results: Regions of stress concentration were seen mostly along the mesiodistal direction compared to that in the buccolingual direction. The cortical bone close to the cervical region of the implant and the cortical bone next to the first thread of the implant experienced peak stress concentration. Increasing the degree of osseointegration resulted in increased von-Mises stresses on the implant-cortical transition region, the implant-cancellous transition region, the cortical bone, and the cancellous bone.

Conclusion: The results show that the application of distinct thread profiles at different degrees of osseointegration had significant effect on the stresses distribution contours in the surrounding bony structure. Comparing all four thread profiles, a dental implant with V-thread profile induced lower values of von-Mises stresses and shear stresses on the implant-cortical transition region, implant-cancellous transition region, cortical bone, and cancellous bone.

Introduction: Jaws-Only Intensity modulated radiation therapy (JO-IMRT) is a technique uses the collimator jaws of the linear accelerator (LINAC) to delivery of complex intensity patterns. In previous studies, pretreatment patient specific quality assurance for those JO-IMRT were also performed using ionization chamber, MapCHECK2, and Octavius 4D and good agreements were shown. The aim of this study is to further verify JO-IMRT plans in 2 different cases: one with the gantry angle set equal to beam angle as in the plans and the other with gantry angle set to zero degree.

Materials and Methods: Twenty-five JO-IMRT, previously verified, were executed twice for each plan. The first one used a real gantry angle, and the second one used a 0° gantry angle. Measurements were performed using Octavius 4D 1500.

Results: The results were analyzed using Verisoft software. The results show that the Gamma average was 97.32 ± 2.21% for IMRT with a 0° gantry angle and 94.72 ± 2.67% for IMRT with a true gantry angle.

Conclusion: In both cases, gamma index of more than 90% were found for all of our 25 JO-IMRT treatment plans.

Probabilistic Model on Buying Decision of Higher Education Services
Authors: Blaga Radu Lucian , Blaga Alexandru
Published: June 2018

Buying decisions are determined by two key factors: endogenous factor that belongs to the buyer (which is present at least the attitudinal variable) and exogenous factors such demo-economic, sociological, psychological, marketing mix, linked all more or less by the product or the service offered for purchase and consumption. The study aims to use Rasch’s model to express the likelihood that a consumer will make the decision to purchase a higher educational service. Applied to item solving, Rasch probabilistic model, on which the research methodology study is largely supported, states that the probability of success in solving an item depends on two factors. The one belongs to that who solves the item - the human factor, called the latent trait, and the other belongs to the item, called the facility of the item The purchase decision approach using the Rasch model results validity is mainly based on the isometry of the two situations The results of the study describe behavioral probability situations where customers who make university education services purchasing decisions can themselves be found. We recommend the educational marketing strategies based on the analysis made on the applied model, which may increase the students’ enrolled number in a particular university.

Authors: Karakikes Ioannis , Hofmann Wladimir , Mitropoulos Lambros , Savrasovs Mihails
Published: June 2018

Simulation modelling tools have been widely adopted for the evaluation of alternatives in transport planning, management and logistics. The complexity that underlies in transport systems and logistics necessitate the integration of different models that are capable of overcoming limitations that may exist individually to each model. Towards this direction, this paper aims to integrate two simulation software and use the integrated model for the evaluation of traffic and logistics measures in the wider area of Volos Port, Greece. The built model is able to simulate the traffic conditions on a transport network along with port’s intra-logistics processes and is used to evaluate a set of measures in the year 2030, by comparing it with the situation in the year 2030 without having implemented any new measure. For the evaluation, a set of indicators is used to gauge the environmental and transport impacts. The analysis is completed by using a multi-criteria decision making tool to generate the Logistics Sustainability Index (LSI) to summarize the information that is provided by the indicators. The results show that the use of integrated simulation models can provide a holistic impact evaluation of complex decisions with a high level of accuracy.

Objetivo: Estudos têm demonstrado mudanças nospadrões de prescrição de antipsicóticos nas últimas duasdécadas, com destaque para o aumento na utilização deantipsicóticos atípicos em relação aos típicos. O objetivodeste estudo foi avaliar longitudinalmente a tendênciade prescrição de antipsicóticos típicos e atípicos (excetoclozapina) e sua associação com o tempo médio deinternação em um hospital psiquiátrico. Métodos: Este foi um estudo ecológico. Dados sobre aprescrição de antipsicóticos e tempo médio de internaçãohospitalar de janeiro de 2007 a dezembro de 2014 foramfornecidos pela farmácia e pelo Serviço de ArquivoMédico e Estatística do Instituto de Psiquiatria de SantaCatarina, respectivamente. Utilizaram-se análises deregressão linear simples para avaliar a associação entreas variáveis independentes e o desfecho. Resultados:Durante os 8 anos de observação doestudo, houve um aumento da prescrição de antipsicóticosatípicos [coeficiente B = 0,0037; intervalo de confiançade 95% (IC95%) 0,0033 a 0,0041; p < 0,001] e reduçãoda prescrição de antipsicóticos típicos (coeficiente B= -0,009; IC95% -0,01 a -0,008; p < 0,001) medidosem dose diária definida. Não houve associação entreprescrição de antipsicóticos, típicos ou atípicos, e tempomédio mensal de internação hospitalar. Foi observadoum aumento na taxa de ocupação hospitalar no período,com frequente sobrelotação. Conclusão: O padrão mundialmente observadode aumento na prescrição de antipsicóticos atípicostambém foi constatado neste estudo. Não houve associação entre esse aumento e o tempo médio deinternação hospitalar. Apesar de não ser objetivo desseestudo, a sobrelotação observada merece atenção dosgestores públicos.

Risks of Preterm Labour among Women Who Attend Public Antenatal Care Clinics
Authors: Fourie Naomi , Du Rand Suzette , Morton David G
Published: June 2018

Preterm births are the leading cause of perinatal morbidity and mortality worldwide. Complications of prematurity are the single largest cause of neonatal death and the second leading cause of deaths among children under the age of five years. The study aimed to identify the possible causes for preterm labour among women who attend antenatal care clinics in the East London area of the Buffalo City Metropolitan Health District in South Africa. A quantitative, explorative, descriptive, and retrospective design was used. The target population was women who delivered preterm infants in the year 2014. Patient files were used to collect the data and simple random sampling was used to select patient files. The sample only included women who delivered preterm infants who received antenatal care at primary healthcare clinics. An audit tool was developed and used to collect data. The findings suggest that many of the women did not receive quality antenatal care with certain tests and procedures being omitted and underreported by nurses, leading to some conditions being poorly monitored or even undiagnosed. In conclusion, many preterm births could be prevented among women who attend antenatal care clinics, provided that they attend early, adhere to return dates and experience quality basic antenatal care services.
Exploration of Mothersâ€™ Expectations of Care during Childbirth in Public Health Facilities in Kumasi, Ghana

It is well established that clientsâ€™ past healthcare experiences influence their further use of that particular service, as well as their recommendations of that service. This also applies to the use of facility-based childbirth services which contribute to reducing maternal and infant mortality rates. This paper explores what mothersâ€™ want from care in public health centres during childbirth. Knowing mothersâ€™ expectations will contribute to improving their future childbirth care experiences. In this explorative qualitative study, 56Â women were recruited from four public health centres. In-depth individual interviews were digitally recorded and transcribed in full, and subjected to content analysis. Themes emerged, revealing participantsâ€™ desire for both â€œrespectful careâ€ and â€œsafe careâ€. From our findings, we posit that respectful care should be characterised by adequate communication between the healthcare provider and patient, and involvement of the patient in care decisions. Participants expected safe care, which results from health facilities with adequate resources. Health services generally concentrate on clinical care which aligns with mothersâ€™ expectations of respectful and safe care. However, soft skills need much attention in nursing and midwifery education. There is also a need to orient midwives to a patient-centred approach to care that meets mothersâ€™ expectations for childbirth care.
The Use of Variables in a Patterning Activity: Counting Dots
Authors: Maj-Tatsis Bożena , Tatsis Konstantinos
Published: June 2018

The present paper examines a patterning activity that was organised within a teaching experiment in order to analyse the different uses of variables by secondary school students. The activity presented in the paper can be categorised as a pictorial/geometric linear pattern. We adopted a student-oriented perspective for our analysis, in order to grasp how students perceive their own generalising actions. The analysis of our data led us to two broad categories for variable use, according to whether the variable is viewed as a generalised number or not. Our results also show that students sometimes treat the variable as closely linked to a referred object, as a superfluous entity or as a constant. Finally, the notion of equivalence, which is an important step towards understanding variables, proved difficult for our students to grasp.
Assessment of School Image

Published: June 2018

There seems to be a gap in the literature on educational management that focuses on school image and its assessment. This paper addresses this issue by reviewing the state of the art regarding school image and communication with the public.School image can be defined as the overall impression and mosaic synthesised from numerous impressions of individuals of school publics (pupils/students, teachers and deputies of schoolmanagement, parents, and other stakeholders). School image is not what the headteachers understand it to be, but the feelings and beliefs about the school and its educational programme that exist in the minds of theschool publics. The present study contributes to the literature by providing an overview of school image and by providing a practical application of a useful tool for assessing the content of corporate image. Semantic differential scales are used for marketing purposes and as a useful technique for measuring and assessing school image. Communication with publics and the development and sustainability of a positive school image influence not only the marketing of the school but also the educational process in the school. Today, shaping and maintaining a school image is even more important because of the curriculum reform, focusing on higher study process outputs, quality assessments, and accountability. The findings of this study have important implications for school marketing experts and researchers, headteachers, education policymakers, as well as teachers at schools.
