An important transition in IT service delivery today is buzzword Cloud Computing. The tools, building blocks and best practices are evolving for cloud computing which in turn increases challenges to deploy the best suited cloud solutions. Initially the big players like Google, Microsoft, Amazon set the stage for how to deploy web applications & pay for their use on the web. Thus with number of platforms and services available to for a cloud it is hard to make a reasonable choice for at least a novice who has just entered into cloud. The paper is intended to provide an insight into few cloud providers’ services with respect to their features and scenarios. This comparison may help in the selection of a platform and may leverage as a starting point for a researcher.

The purpose of the study is to explore the more fields of customer based brand equity in Pakistan telecom sector. Moreover, an effort has made to view the existence of relationship between the brad equity factors. The questionnaire was distributed among the respondents by following the simple random sampling technique. Questionnaires were distributed among 315 respondents. Out of which only 207 were capable for properly filled. Data was analysed through SPSS and relationships between proposed variables was checked through Structural Equation Modelling (SEM). The findings of this study show a significant positive relationship among the four factors of brand equity. The relationships among perceived quality, brand awareness and brand associations are found to be quite strong while the relationship between these three variables and brand loyalty was relatively weaker. This research study highlights the area where companies should focus to gain a sustainable competitive advantage. Further research can be done to find out the root causes of the factors that weaken the relationship of brand loyalty with other variables.

The purpose of this study was to extend the existing body of knowledge on course stress related with university students. A conceptual framework which illustrates four dimensions of coursework stress including coursework worries, lack of skills to perform coursework, dis-likeness towards coursework and attitudinal problems in performing coursework was developed. The present research was a descriptive study which used an indigenous research instruments to measure the coursework stress in the context of university students. The study was carried out on a sample of 100 university students which explored the impact of demographic variables including gender, age, and discipline, employment of the students and level of education on determining the level of coursework stress. Result of the study revealed that the phenomenon of coursework stress does exist among the university students. Female students and younger students experience higher coursework stress, as compared to male and older students. The findings also indicated that different demographic variables contribute significantly in determining the level of coursework stress among M. Phil and PhD. students.

Composites are finding increased use in structural applications, in particular for aerospace and automotive purposes. Fiber reinforced composite possess high strength and stiffness. Some of these materials perform equally well or better than many traditional metallic materials. In addition, fatigue strength-to-weight ratios as well as fatigue damage tolerance of many composite laminates are excellent. To analyze metallic structures, properties of metals are easily available, but for composite structures properties of composite material are not readily available. Composite material is nothing but a laminate made from number of different lamina, and the properties of laminate depends on properties of lamina. The material properties of composite are required for carrying out stress analysis and fatigue analysis which in turn predicts the life of component. Objective of present work is to study the behavior of composite materials. This investigation deals with lamina composed of polymer matrix and carbon fibers. The aim of this study is to determine following properties. • Elastic properties, thermal properties and strength properties of transversely isotropic lamina by all methods of Micromechanics. • Properties of orthotropic lamina using Method of Cells. • Verifying the results predicted by Method of Cells with the other micromechanics methods like Composite Cylinder Assemblages (CCA) method, Rule of Mixture, Halpin-Tsai, Chamis method and Zing-ming Huang method.

There is an optimum time for implementing field operation of various crops in each region. If the operation is accomplished sooner or later, it will cause a reduction in yield quantity and quality. The cost of this reduction is named “timeliness cost”. Annual timeliness cost is estimated by an equation reported in ASAE standards. MF285 tractors have low reliability in Iran. Generally, low tractor reliability has an uncertainty in implementation of farm operation which it is not considered in ASAE equation for calculating of timelines cost. This uncertainty causes a cost being a part of timeliness cost and is produced due to tractor failure within farm operation. The purpose of this study was to determine the reliability function of MF285 tractors operated in Debal Khazaei Agro-Industry Co. in Khuzestan province of Iran. Thus, in this study a function-fit model for reliability of farm tractors was determined. Afterwards, tractors working times to a failure (hours) in tenth year of tractor life were fitted with normal, exponential, lognormal, poisson and weibull age distribution functions using moment estimation. Depending on Chi square test, the best reliability function for this given situation was exponential distribution function with ? = 0.025.

In private cloud during FFCS registration large amount of students are trying to register their subject at same time from different places so heavy load is departing to server due to this heavy load to resources the server unable to give where response to students which lead to the problem student can’t register properly within given time or wait for long time until server recover from this problem. This problem can be solved by allocating the resources properly to server this comes under the infrastructure as a service (IaaS) we can use and allocate a various kind of resources. This paper proposed solved this problem efficiently according virtual machine is distributed in hierarchical architecture using dynamic round robin algorithm[DRR] , resources will be allocate efficiently so the load will be distributed to various virtual machine then student need not to wait for long time and they can register properly within a given time. Finally implemented on Simulator Cloudsim 3.0. Experiment result show DRR can achieved resource allocation efficiently in cloud computing.

Our information-gathering behavior has always been to find out what other people think. Opinion-rich resources such as online review sites and personal blogs are growing rapidly which provide new opportunities and challenges, as people can actively use information technologies to seek out and understand the opinions of others. People share their experiences on-line, express their opinions, frustrations about anything. The huge amount of available data creates opportunities for automatic mining and analysis. It can be considered as a classification task: their feelings can be positive, negative or neutral. People don’t directly express sentiment, They can also use a diverse range of other methods to express their emotions. Authors may mix objective and subjective information about a topic, or write down psots about other topics than the one we are investigating. And also there is a lot of noise in the data gathered from the Web pages. Due to this the task of automatic recognition of the sentiment in on-line text becomes more difficult. The content we are interested in this paper is, what is sentiment analysis, how the sentiment analysis was useful for a bank, how can it be applied in market intelligence and what are the challenges that could be faced in Indian scenario.

While since a rather long time ago teacher feedback has received a lot of attention in learning a foreign language, quite recently, a gradual but prominent shift has taken place within the field of education, resulting in greater emphasis on learners and learning and less stress on teachers and teaching (Hismanoglu, 2000). An outcome of this event has been more emphasis on language learning strategies (Oxford, 1990). As another sign of increasing emphasis on learners, many studies have focused on the use of journals in EFL classes (Park, 2003). However, the present researcher failed to find any published research on how teacher feedback on EFL students’ journals can contribute to strategies they use for learning English as a foreign language. Thus, this study was conducted to explore contributions of teacher constructive feedback on Iranian EFL students’ journals to their use of language learning strategies. A group of EFL learners received a 3-month treatment of feedback-based journal writing and a control group did not receive any treatment. Prior to and following the treatment, the SILL was administered to the groups. Then, they were required to write journals which were followed by teacher constructive feedback for eight sessions. Pertinent statistical analyses showed that feedback-based journal writing does not have any significant effects on the use of learning strategies by EFL learners. However, longitudinal studies are suggested so that further realities of mental processing can be explored.

Dynamism pumps the blood to the body of society; therefore, the dynamic and communicative nature of language can not only be considered integral in teaching, but also in assessing a language. Recently, all over the world traditional ways of assessment are trading place with more communicative ones. The primary purpose of this study was to investigate whether dynamic and formative assessment had significantly different impact on improving the listening skills of Iranian EFL Learners. To do so, 90 intermediate male and female learners from a language school in Tehran were elected. A piloted PET was administered as homogeneity test and 60 learners were selected as the participants and randomly assigned into two groups of thirty. To make sure that there is no statistically significant difference between the performances of the two groups in the beginning of the research a listening pretest of PET was administered in both experimental groups. In one group dynamic assessment, through teaching metacognitive strategies, was administered on learners' listening skills, while the other group's listening skill was assessed formatively. After fourteen sessions a posttest of PET was administered for both groups. The evaluation of the findings showed that the dynamically assessed group outperformed the formative one.
