Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

This paper aims to focus on solving the path optimization problem by modifying the probabilistic roadmap (PRM) technique as it suffers from the selection of the optimal number of nodes and deploy in free space for reliable trajectory planning.

Traditional PRM is modified by developing a decision-making strategy for the selection of optimal nodes w.r.t. the complexity of the environment and deploying the optimal number of nodes outside the closed segment. Subsequently, the generated trajectory is made smoother by implementing the modified Bezier curve technique, which selects an optimal number of control points near the sharp turns for the reliable convergence of the trajectory that reduces the sum of the robot’s turning angles.

The proposed technique is compared with state-of-the-art techniques that show the reduction of computational load by 12.46%, the number of sharp turns by 100%, the number of collisions by 100% and increase the velocity parameter by 19.91%.

The proposed adaptive technique provides a better solution for autonomous navigation of unmanned ground vehicles, transportation, warehouse applications, etc.

The purpose of this paper is to investigate the impact of reciprocity in privacy settings on the compromises and losses in utility encountered by users. The authors base our study on WhatsApp because of the inherent reciprocity in its privacy settings to understand users’ preferences and reasoning in choosing a particular setting in light of its reciprocal consequence.

The authors present a qualitative study whereby we conducted a series of in-depth interviews with 15 individuals, representing a range of ages, nationalities, work experience and WhatsApp usage frequency. The interviews were semi-structured and thematic analysis was employed.

The results showed that reciprocity has a strong influence on privacy choices, and users over time adjusted their settings continuously in various ways to balance the overall utility of the application and their privacy. Type of contacts, usage frequency and underlying intent in using the application significantly impact privacy choices.

The findings recommend improved design for Mobile Instant Messaging that enables flexible privacy configurations that can be controlled separately for different groups and for individual contacts.

The paper provides original insights into how reciprocity affects the utility of the application and the privacy choices of the users. The investigation is unique in that the authors know of no other study that looked into the notion of reciprocity and how it affects users’ privacy choices and preferences when built in to Mobile Instant Messaging applications. Overall, the authors believe that this paper adds significantly to a growing body of research on privacy and social media.

Under the constraints of given passenger service level and coupling travel demand with train departure time, this study optimizes the train operational plan in an urban rail corridor to minimize the numbers of train trips and rolling stocks considering the time-varying demand of urban rail passenger flow.

The authors optimize the train operational plan in a special network layout, i.e. an urban rail corridor with dead-end terminal yard, by decomposing it into two sub-problems: train timetable optimization and rolling stock circulation optimization. As for train timetable optimization, the authors propose a schedule-based passenger flow assignment method, construct the corresponding timetabling optimization model and design the bi-directional coordinated sequential optimization algorithm. For the optimization of rolling stock circulation, the authors construct the corresponding optimization assignment model and adopt the Hungary algorithm for solving the model.

The case study shows that the train operational plan developed by the study's approach meets requirements on the passenger service quality and reduces the operational cost to the maximum by minimizing the numbers of train trips and rolling stocks.

The example verifies the efficiency of the model and algorithm.

The intention of this paper is to compare the performance of five Chipmunk aircraft, and to investigate the assumption that the performance of any operational aircraft can be considered to be representative of that type of aircraft. All the aircraft were tested, with the same instrument panel fitted, and were weighed in order to determine the variation in weight and centre of gravity. Flight tests were then conducted to investigate the following aspects of performance: turning, climbing, drag, engine power, stalling and spinning. The results, reduced from the readings taken during flight tests, showed that there are two main causes of variation between the performances of the aircraft. First the age and condition of the engine were seen to affect the power dependent aspects of performance. Secondly there was a wide variation of profile drag which was probably due to distortion of the airframes.

This paper explores the ability of the capital asset pricing model, as well as the firm specific factors, to explain the cross‐sectional relationship between average stock returns and risk in Athens Stock Exchange (ASE). The objective of this study is to investigate the cross‐section of stock returns in the Greek stock market for the period from July 1993 to June 2001. A methodology similar to that of Fama and French (1992) is employed, by taking into account the constraints imposed by a smaller sample both in time and in terms of number of stocks. Our findings indicate that in the Greek stock market there is not a positive relation between risk, measured by β, and average returns. On the other hand, there is a “size effect” on the cross‐sectional variation in average stock returns.

Sees the objective of teaching financial management to be to help managers and potential managers to make sensible investment and financing decisions. Acknowledges that financial theory teaches that investment and financing decisions should be based on cash flow and risk. Provides information on payback period; return on capital employed, earnings per share effect, working capital, profit planning, standard costing, financial statement planning and ratio analysis. Seeks to combine the practical rules of thumb of the traditionalists with the ideas of the financial theorists to form a balanced approach to practical financial management for MBA students, financial managers and undergraduates.

This study focuses on handling times of turn round cycles and on the adjustments of airports and processes in order to get ready for the A380. Turn round time (TRT) is defined as the time spent between arrival and departure at a handling facility or gate. First, analyses were done on current aircraft handling processes and whether these could be used for the A380. The study then focuses on alternative handling methods for the A380, and recommendations are made.

Path planning is a fundamental and significant issue in robotics research, especially for the legged robots, since it is the core technology for robots to complete complex tasks such as autonomous navigation and exploration. The purpose of this paper is to propose a path planning and tracking framework for the autonomous navigation of hexapod robots.

First, a hexapod robot called Hexapod-Mini is briefly introduced. Then a path planning algorithm based on improved A* is proposed, which introduces the artificial potential field (APF) factor into the evaluation function to generate a safe and collision-free initial path. Then we apply a turning point optimization based on the greedy algorithm, which optimizes the number of turns of the path. And a fast-turning trajectory for hexapod robot is proposed, which is applied to path smoothing. Besides, a model predictive control-based motion tracking controller is used for path tracking.

The simulation and experiment results show that the framework can generate a safe, fast, collision-free and smooth path, and the author’s Hexapod robot can effectively track the path that demonstrates the performance of the framework.

The work presented a framework for autonomous path planning and tracking of hexapod robots. This new approach overcomes the disadvantages of the traditional path planning approach, such as lack of security, insufficient smoothness and an excessive number of turns. And the proposed method has been successfully applied to an actual hexapod robot.

THERE are times when a great accretion of the resources available to man changes the human environment. This country experienced such a change two centuries ago and it lives in history books as the Industrial Revolution. It didn't happen overnight for the various factors, from Kay's flying shuttle to Watt's steam engine, covered something like fifty years. In the end it completely altered the character of the country. Cottage industry was eliminated and factories spread rapidly. There was a vast increase in the population and the expansion of industrial production made all previous progress insignificant.
