RSRP: A Robust Secure Routing Protocol in MANET

Abstract In this paper, we propose a novel algorithm RSRP to build a robust secure routing protocol in mobile ad-hoc networks (MANETs). This algorithm is based on some basic schemes such as RSA_CRT for encryption and decryption of messages; CRT for safety key generation, Shamir’s secret sharing principle for generation of secure routes. Those routes which are free from any malicious node and which belong to the set of disjoint routes between a source-destination pair are considered as probable routes. Shamir’s secret sharing principle is applied on those probable routes to obtain secure routes. Finally, most trustworthy and stable route is selected among those secure routes. Selection of the final route depends on some criteria of the nodes present in a route e.g.: battery power, mobility and trust value. In addition, complexity of key generation is reduced to a large extent by using RSA-CRT instead of RSA. In turn, the routing becomes less expensive and most secure and robust one. Performance of this routing protocol is then compared with non-secure routing protocols (AODV and DSR), secure routing scheme using secret sharing, security routing protocol using ZRP and SEAD depending on basic characteristics of these protocols. All such comparisons show that RSRP shows better performance in terms of computational cost, end-to-end delay and packet dropping in presence of malicious nodes in the MANET, keeping the overhead in terms of control packets same as other secure routing protocols.
Impacts of cognitive media attributes and motivation on IPTV adoption: exploring the moderating effects of agricultural information

The agricultural and food industries are excited by and looking forward to employing Internet Protocol Television (IPTV) as they see it as a viable means of promoting their markets. Based on the Stimulus-Organism-Response (S-O-R) framework, this study investigates how the technological and ambient environments of media characteristics influence viewer cognitive and emotional states, and how experiences subsequently affect their responses. This study examines whether the effects of media attributes and motivations affect viewer cognitive necessity and usefulness with respect to adopting specific media. The results of our survey of 254 observations collected indicate that interactivity has a significant positive impact on flow, relaxation, and enjoyment. Ease of use is significantly associated with flow, relaxation, and enjoyment. Senses of both professionalism and familiarity are found to significantly influence viewer cognitive and emotional states. This study finds that the gathering of agricultural information moderates the relationship between the three factors of cognitive and emotional states and behavioral intention to adopt IPTV such that the relationships are stronger for those factors that are related to a stronger sense of information gathering. The results should enable agricultural and food related business owners to obtain insight into using interactivity effectively to propel their businesses forward.
Research and Publication Patterns in Library and Information Science

The research and publication patterns of thirty-four topranking researchers in library and information science (LIS) in Africa were surveyed. The researchers produced 294 papers during the 1990–1995 period which were considered for this study. The findings reveal that majority of the researchers were from universities and were based mainly in Nigeria and South Africa. The principal research centres, however, were the Department of Library and Information Studies, University of Botswana and the Faculty of Information Sciences, Moi University, Kenya. The research investigations concentrated mainly on professional education, information science, library management and information technology. Of the fifteen top ranked journals used by the researchers, only two were published in Africa.
English as a foreign language learners’ perception of mobile assisted language learning: a cross-national study

While mobile devices are gradually starting to play an important role in the everyday lives of students, learning English on mobile phones is no longer a novelty for English as a foreign language (EFL) learners. While there is a wealth of literature that discusses the application of information and communication technologies (ICTs) in EFL education, studies on mobile assisted language learning (MALL) are still needed. This study aims to investigate the end-user's perception of MALL through cross-cultural analyses. Forty-five participants (n = 45) from seven different countries/regions voluntarily participated in this project. Cross-cultural analyses were conducted with three proposed constructs: technological affordances, applicability and the constructivism of MALL. Results of the Kruskal–Wallis ANOVA and Dunnett's T3 multiple comparison revealed that significant differences did exist among participants with different cultural backgrounds. Even so, all participants agreed that MALL is a potential tool for constructivism in EFL learning.

Bacterial Profile Associated with Dental Caries in Jos, Nigeria

Aims: The study was aimed at determining bacterial prevalence and their susceptibility to commonly used antibiotics. Study Design: The research was a cross sectional study which cuts across all age group and gender. Place and Duration of Study: The study was carried out at the Bacteriology Laboratory of Original Research Article Okopi et al.; AIR, 4(6): 371-377, 2015; Article no.AIR. 2015.091 372 Department of Medical Microbiology, Federal College of Veterinary and Medical Laboratory Technology, Vom, Jos, Nigeria, between July and September 2014. Methodology: We included 150 patients (30 men, 120 women; age range 11-70 years) who gave consent to be included in the study. Swabs were taken from dental plaque and inoculated on basal salt medium containing yeast and bacterial colonies obtained were identified biochemically according Bergey’s Manual of Systematic Bacteriology. Antibiotic susceptibility test was then conducted on the isolates identified. Results: Ninety-five (63.3%) patients had cavities located at the molars, forty-five (30%) between molar and premolar and ten (6.7%) located at the gingival margin. One hundred and twenty (80%) samples were obtained from female patients and thirty (20%) from male patients. Lactobacillus species had the highest occurrence (28.8%). The least was Fusobacterium species (0.7%). The antibiotic susceptibility test revealed that Enterobacter species was resistant to all the three antibiotics used in this study. Bacillus subtilis and Staphylococcus were resistant to erythromycin and vancomycin but sensitive to all the three antibiotics. Conclusion: A few common acidogenic bacteria known to colonize dental plaque were identified. Susceptibility of the various bacterial isolates to the selected antibiotics varied. Further studies on susceptibility of these bacteria to commonly used antibiotics, antibacterial mouth washes and toothpastes are necessary in order to understand their epidemiology, to limit the spread of resistant bacteria. Larger sample size studies with better isolation, identification and characterization methods are needed. These studies could lead to the identification of strategies for effective biological interventions in the caries process and thereby contribute to improved prevention and treatment.

Cross-Age Study Of The Understanding Of Some Concepts In Chemistry Subjects In Science Curriculum

The alternative ideas and misconceptions of the students play an important role in the studies of chemistry education in science. Among these, the cross-age studies could easily point out the comprehension levels of students from different age groups. The basis of the chemistry education is constructed at schools through having the students understand and use the concepts of atom and molecule. The cross-age study was conducted with a total of 239 students (138 male, 101 female) aged 11, 12, 13 and 14 from 6 th , 7 th and 8 th
Landscape Metrics and Visual Topology in the Analysis of Landscape Preference

Recognition of the value of landscapes, environmentally, economically, and to quality of life—and, importantly, the embedding of these concepts in legislation such as the European Landscape Convention—has led to the need for an ‘objective’ assessment of these values and the potential impact of changes to them. But studies relating preference information to metric analysis of planimetric viewsheds have so far provided only limited explanation of preference. It has been suggested that this is due to the effect of perspective on the visual topology of the view generating different metrics in perspective from those on the flat map. The completion of the Pan European Study under the EU Framework 5 Visulands project provided a large sample of preference responses to a limited number of computer-generated simple landscape scenarios. As such this is an ideal opportunity to test the significance of perspective on metric correlation with preference. This paper considers the degree to which metrics are altered by a panoramic or viewshed analysis, and the significance of this for any correlation with the preference scores. The implications for the role of the respective media in planning are considered, including that of 3D visualisation as a means for eliciting opinion on landscape preference.

The human side of the triangle: using green textile standards to address social responsibility

Textile specification in the interior design field has evolved to include attributes in addition to aesthetics, cost, building occupant health and safety, and specialized performance criteria. Initially, “green” specifications addressed environmental impact reduction through renewable, recycled, recyclable, nontoxic and low-emitting materials. Worldwide, third-party certifications continue to expand sustainable attributes to include social equity impacts on human health, safety, training and compensation throughout the product life cycle. Comprehension of these new assessment tools is essential for designers to effectively balance economic, environmental, and social responsibility. Although social responsibility has been discussed in the context of global sustainable development since the 1970s, third-party evaluation attempts to systematically connect the effects of product manufacture, use, and disposal to the human condition are relatively recent. Environmental and social impacts are interrelated, but not interchangeable. Social equity criteria are not addressed uniformly in textile certifications. This paper presents research on designers’ perceptions of social responsibility, awareness of social issues in the textile life cycle, and prioritization of textile specification criteria. The study also considers to what extent designers take responsibility for sustainable design decisions, and if sustainable design is becoming a standard practice. The analysis focuses on responses generated by a questionnaire distributed through an online interior design publication based in Texas (USA) and distributed internationally.
Moving‐image simulation for high‐quality LCD TVs

Abstract— A simulation system incorporating pixel response and eye‐trace integration was developed to evaluate the moving‐image performance of high‐quality LCD TVs. A simple formula was derived for moving‐edge simulation, which can be used to evaluate the visual effects of arbitrary response waveforms. A model of exponential decay with dynamic time constants is proposed for the LC response to perform moving‐image simulation. The model was used to evaluate the visual effects of various motion‐blur‐reduction techniques. Six different motion‐blur‐reduction techniques were evaluated in terms of their visual effects. Among them, three basic techniques show certain defects, which are further analyzed by simulation. The other three advanced techniques show excellent performance, and, therefore, are recommended for use in high‐quality LCD TVs.
Automatic feature template generation for maximum entropy based intonational phrase break prediction

The prediction of intonational phrase (IP) breaks is important for both the naturalness and intelligibility of Text-to- Speech (TTS) systems. In this paper, we propose a maximum entropy (ME) model to predict IP breaks from unrestricted text, and evaluate various keyword selection approaches in different domains. Furthermore, we design a hierarchical clustering algorithm for automatic generation of feature templates, which minimizes the need for human supervision during ME model training. Results of comparative experiments show that, for the task of IP break prediction, ME model obviously outperforms classification and regression tree (CART), log-likelihood ratio is the best scoring measure of keyword selection, compared with manual templates, templates automatically generated by our approach greatly improves the F-score of ME based IP break prediction, and significantly reduces the size of ME model.
Integration of process planning and scheduling through adaptive setup planning: a multi-objective approach

The integration of process planning and scheduling is considered here as a multi-objective optimisation problem in reconfigurable manufacturing settings where more than one machines (3-axis, 4-axis and 5-axis machine configurations) are available to manufacture a part. In this research, machining features are grouped according to tool approach direction considering the criteria such as makespan, machining cost and machine utilisation. We have also addressed adaptive characteristics of process plan associated with setup i.e. a cross-machine setup planning to capture the different configuration of machines. To solve this type of multi-objective problem, a meta-heuristic, non-dominated sorting algorithm (NSGA-II) is applied to take into account the computational intractability of the problem. Further, a fuzzy set theory approach is developed to extract one of the Pareto-optimal solutions as the best compromising one. Illustrative examples are trialled to demonstrate the capability of the proposed model. The results confirm that the proposed multi-objective optimisation model gives robust performance in developing optimal adaptive setup plan.
The Principles of Selection

AbstractThe fundamental of cartographic generalisation, the reduction of the amount of information which can be shown on a map in relation to reduction in scale, is examined. The Principle of Selection was first proposed by Topfer in 1961, and is expressed as an equation relating the number of occurrences of a particular feature at source map scale and at derived map scale. The application of this to small-scale maps involves the introduction of two constants to represent symbolic exaggeration and symbolic form. Examples are given and illustrated. The paper is accompanied by explanatory notes by Dr D. H. Maling, who presented the paper on behalf of the authors at the XX International Geographical Congress London 1964, Section IX, Cartography.
Retaining the Online Learner: Profile of Students in an Online MBA Program and Implications for Teaching Them

Research regarding student cohorts entering the Georgia WebMBA$$ program (an online MBA program in the University System of Georgia) shows consistent demographic characteristics as well as students' reasons for joining the program, experience with online learning, and perceptions of teamwork. The program has a high retention rate, and in this article the authors focus on retaining online learners. They discuss the profile of program students and the teaching approaches that have been successful in addressing potential attrition issues with these learners. To retain virtual learners, the program provides a cohort- and team-based learning experience with extensive faculty feedback and interaction to address isolation concerns, provide application-based content and activities, and help students meet expectations for personal and professional growth. The authors also stress the need to offer a well-managed program and faculty members who are both interested and competent in teaching in the online learning environment.
Simulation of the suspension of a vehicle using Chebyshev series

This article presents approximate analytical solutions of the differential equation system governing the vertical dynamics of a vehicle, using an approximation through expansions in Chebyshev series. These solutions allow faster solution processing than do the traditional numerical methods. The Lanczos τ method is used in order to obtain lower-degree polynomials with much reduced errors for the simulation times proposed. Finally, an analysis of the computational efficiency of the outcomes is carried out, comparing the time spent in processing exact and numerical solutions of the system with the time taken by this expansion method using Chebyshev series. It can be checked that the calculations of these polynomials are far more efficient with low-degree excitations.
Analysis of Pressure Tests Through the Use of Instantaneous Source Response Concepts

A general method of analysis for pressure transient tests is presented. This technique is based on the pressure response of an instantaneous source and it provides a mean to compute the first and second derivatives of the influence function (unit flow rate response) of the well-reservoir system. This information is basic in identifying the flow regimes occurring during the test. This method eliminates the effect of producing time on pressure buildup data. An explicit and stable procedure is discussed to compute both the derivatives of the influence function and the initial reservoir pressure. This technique is suitable for DST and Repeat Formation Tests as well as for pressure buildup and fall off tests with long shut in period; variable flow rate before shut in can be taken into account. Examples of application are presented.
The Growth of Phonological Awareness by Children With Reading Disabilities: A Result of Semantic Knowledge or Knowledge of Grapheme-Phoneme Correspondences?

According to the Lexical Restructuring Model (Metsala & Walley, 1998), children move from holistic representations of words, to syllabic representations, and finally to phonemic representations through a restructuring process driven by their developing lexical base. In contrast, the psycholinguistic grain size theory put forth by Ziegler and Goswami (2005) suggests that the awareness of individual phonemes is not possible without direct literacy instruction. The purpose of this study was to examine whether semantic knowledge and/or knowledge of grapheme/phoneme correspondences influenced the acquisition of word-blending skills by a sample of children with a reading disability. Participants were 211 second-grade and third-grade students from public elementary schools who were assigned to a reading intervention. Hierarchical Linear Modeling techniques were used to model individual growth curves of word-blending skills. Overall, findings support the psycholinguistic grain size theory of reading and suggest that instruction in the relationship between orthographic patterns and their corresponding sounds is necessary for the development of phonological awareness.
