Mobile ad hoc networks are becoming very popular in wireless communications due to the latest advances in technology. This has allowed millions of people to communicate with each other over wireless networks using mobile devices. Moreover, the latest models of many vehicles are equipped with communication devices which allow them to form a new type of ad hoc wireless networks, called Vehicular ad hoc Networks (VANETs). The main goal of VANETs is to increase the road safety and to reduce the human casualties by communicating critical data between vehicles thereby facilitating time-critical actions, as well as, entertaining the passengers. In this paper, we study the performance of many hybrid routing protocols in vehicular ad hoc networks to communicate multimedia traffic. © Research India Publications.

Cancer is one of the deadliest diseases which require immediate attention by the sufferer as well as his doctors and hospital support staff. Its cure may not be completely possible for a number of reasons. Patients and their attendants undergo series of decision making processes to carry out its treatment. Experiences of patients are therefore considered very important for the best handling of this disease. In third world countries like Pakistan; choice of hospitals, expenses, amount of travel to the hospital by patients and treatment given by the doctors and nurses at hospital plays a vital role in early recovery. Data of patients is recorded in medical logs as well as reports of their handlers. This information is of considerable importance for new patients aspiring to have sound treatment in any hospital. Present research was focused on 30 cancer patients undergoing cancer treatment at two premier hospitals of Islamabad Pakistan for over an year. Their experiences were recorded through a questionnaire answered. It lead to inferences about various factors such as waiting time for treatment, expenses on tests, travel to hospitals, attention given by the hospital staff and doctors and administrative problems faced. This research provides information on various factors for selecting a hospital for patients and hospital management staff to understand the expectations to help them provide better services.

In this paper, we introduce the notion of a partially a-contractive self mapping and prove the existence and uniqueness of a fixed point for such mapping. Our results improve and generalize many results in S-metric spaces. © 2016 NSP Natural Sciences Publishing Cor.


Undoubtedly, climate change is one of the greatest problems facing today’s world. Despite this, traditional research has ignored the market response to, and accountability for, climate change reporting in developing countries. Hence, this study critically examines climate change reporting practices in the most affected countries in the world, with specific reference to Bangladesh. In the study, 32 semi-structured interviews and 71 annual reports are evaluated. Using legitimacy theory, the study contributes to building an understanding of companies’ attitude toward stakeholder accountability regarding climate change. The study finds that Bangladeshi companies are reporting climate change information on an average of 2.23 %. More specifically, the study demonstrates that large companies are reporting on more climate change issues than others because of their legitimized positions in the market. Again, a lack of regulation and a culture of low social accountability among the companies contribute to a very low level of disclosure on climate change. Surprisingly, multinationals are not providing satisfactory disclosure. The study has policy implications in developing countries for both local policy makers (the government) and international policy makers (the Intergovernmental Panel on Climate Change, the European Union, the World Bank, the UN Environment Programme, the International Energy Agency and the World Economic Forum) as to how to engage local companies so that they become more socially accountable to climate change reporting. © 2015, Springer Science+Business Media Dordrecht.


The left-sided truncated normal distribution is especially important in quality engineering where we remove the left side of the distribution, for example, due to estimation of the life of used products. Although the theoretical background of truncated normal distribution is already established, there is very little work on mathematical approximation of the probability density and the cumulative probability density functions. In this article, a high accuracy mathematical approximation of the left-sided truncated normal distribution is proposed. A full analysis of errors and recommendations for implementation using Microsoft Excel are provided at the end of this article. © 2016 Taylor & Francis Group, LLC

Azam et al. (2011), introduce the notion of complex valued metric spaces and obtained common fixed point result for mappings in the context of complex valued metric spaces. Rao et al. (2013) introduce the notion of complex valued b-metric spaces. In this paper, we generalize the results of Azam et al. (2011), and Bhatt et al. (2011), by improving the conditions of contraction to establish the existence and uniqueness of common fixed point for two self-mappings on complex valued b-metric spaces. Some examples are given to illustrate the main results. © 2014 Aiman A. Mukheimer.

The purpose of this article is to analyze current vision-based systems from a soccer video semantic point of view such as video summarization, features analysis, and provision of augmented information. Currently, computer vision techniques are applicable in a challenging soccer context. Scene interpretation is performed based on the complexity of the semantic. For each area of vision-based systems, computer vision methodologies are analyzed along with their strengths and weaknesses. We have also investigated whether the existing approaches are equally applicable for real-time soccer video semantic analysis. © 2013 Taylor & Francis Group, LLC.

Recent studies in different parts of the world have highlighted that phrasal verbs constitute a learning difficulty for English language learners despite their confirmed significance and high productivity in English. Proposed explanations include cross-linguistic differences, the complex nature of phrasal verbs, low language proficiency and psychological factors. The present study examines this difficulty among an Arabic-speaking population of Egyptian undergraduates in a foreign language context. To this end, a total of 407 Egyptian undergraduates in a private English-medium university completed a paraphrase task, two gap-filling tasks and a survey. The results confirm the difficulty highlighted in earlier studies, particularly at the production level. The results also show that the under-representation of phrasal verbs in the participants’ production can be interpreted in terms of cross-linguistic differences, passive learning for comprehension and limited language exposure. The study thus supports a multi-faceted model for the explanation of the limited use of phrasal verbs by English language learners, and calls for a revision of the English language teaching programs in Egypt. © 2016, Australian International Academic Centre PTY LTD.

This paper proposes a new approach to extract global image features for the purpose of texture classification. The proposed texture features are obtained by generating an estimated global map representing the measured intensity similarity between any given image pixel and its surrounding neighbors within a certain window. The intensity similarity map is an average representation of the texture-image dominant neighborhood similarity. The estimated dominant neighborhood similarity is robust to noise and referred to as image dominant neighborhood structure. The global rotation-invariant features are then extracted from the generated image dominant neighborhood structure. Features obtained from the local binary patterns (LBPs) are then extracted in order to supply additional local texture features to the generated features from the dominant neighborhood structure. Both features complement each other. The experimental results on representative texture databases show that the proposed method is robust to noise and can achieve significant improvement in terms of the obtained classification accuracy in comparison to the LBP method. In addition, the method classification accuracy is comparable to the two recent LBP extensions: dominant LBP and completed LBP. © 2011 IEEE.

Purpose – The purpose of this paper is to investigate a lean manufacturing metric called Takt time as a benchmark evaluation measure to evaluate a public hospital’s service quality. Lean manufacturing is an established managerial philosophy with a proven track record in industry. A lean metric called Takt time is applied as a measure to compare the relative efficiency between two emergency departments (EDs) belonging to the same public hospital. Outcomes guide managers to improve patient services and increase hospital performances. Design/methodology/approach – The patient treatment lead time within the hospital’s two EDs (one department serves male and the other female patients) are the study’s focus. A lean metric called Takt time is used to find the service’s relative efficiency. Findings – Findings show that the lean manufacturing metric called Takt time can be used as an effective way to measure service efficiency by analyzing relative efficiency and identifies bottlenecks in different departments providing the same services. Originality/value – The paper presents a new procedure to compare relative efficiency between two EDs. It can be applied to any healthcare facility. © Emerald Group Publishing Limited.
