Generalization Capabilities of Feedforward Neural Networks for Pattern Recognition

This paper studies the generalization capability of feedforward neural networks (FNN).The mechanism of FNNs for classification is investigated from the geometric and probabilistic viewpoints. It is pointed out that the outputs of the output layer in the FNNs for classification correspond to the estimates of posteriori probability of the input pattern samples with desired outputs 1 or 0. The theorem for the generalized kernel function in the radial basis function networks (RBFN) is given. For an 2-layer perceptron network (2-LPN). an idea of using extended samples to improve generalization capability is proposed. Finally. the experimental results of radar target classification are given to verify the generaliztion capability of the RBFNs.

An Investigation of Chinese Undergraduates’Ability to Translate Chinese Cultural Items into English and Predictors of Such Ability

College English teaching in China has long focused on importing cultures of English countries while neglecting to enhance students’English competence in home culture.The present research aims to investigate Chinese non-English major undergraduates’competence in translating Chinese cultural items into English and the significant predictors of such competence.With a test and a questionnaire as research instruments,this study was conducted to assess 82 undergraduates’ability to translate three different levels of Chinese culture-specific items into English and explored the factors which might have affected the students’home culture translation ability.The results show that the participants did well in translating the surface layer cultural items,but their performance in sub-surface and deep layer culture translation tasks was far from being satisfactory.It was also found that students had positive attitudes towards Chinese culture and were willing to learn to express Chinese culture in English,but their English learning motivation in general was not strong enough,and they were not given much input on Chinese culture in their English class.Students’Chinese cultural knowledge and their awareness of the importance of learning Chinese culture in English were found to be the two significant factors that can predict their performance in the translation tasks.These findings have implications for the teaching of culture and cross-cultural communications in EFL classes.

The optimal power distribution in cooperative communication relay system

In order to optimize power utilization of relay nodes in cooperative communication,a power allocation algorithm with objective function to maximize system capacity is proposed.Based on the convex optimization theory,an ellipsoid algorithm is used to solve this problem,which could simplify the subgradient choosing steps and improve convergence stability,so that an optimized power allocation algorithm is presented.Theoretical analysis and simulation results show that the algorithm can effectively distribute the power of each node with lower complexity,and ensure the transmission capability of relay nodes in cooperative communication.

Using Social Media to Promote Intercultural Communication Between Chinese and American University Students

This paper reports a five-year computer-mediated intercultural exchange project between Chinese and American university students that explores the use of various social media tools with WeChat application as the main medium in collaborative intercultural assignments. The study combines quantitative and qualitative approaches by using questionnaires and action research, to investigate how Chinese EFL and American CFL learners increase their intercultural communication competence by assessing their knowledge, awareness, attitudes, and skills of discovery and awareness. The findings reveal their changes and progress in the following variables: knowledge about the variety and subtlety of both the home and target cultures, a different worldview, and cultural study methods;awareness of the importance of differences and similarities between the home and target cultures, their negative reactions to these differences(e.g., fear, ridicule, disgust, feeling of superiority, etc.) and therefore, critical evaluation of the target and home cultures;attitudes from excitement or blind admiration of the target culture to confusion, anxiety or frustration about the cultural differences, later to toleration and appreciation of cultural differences, adaptation to the target culture, and eventually to openness and readiness to suspend disbelief about other cultures and belief about one’s own;skills to contrast the target culture with their own, to demonstrate a capacity to interact appropriately in a variety of different social situations in the target culture and resolve cross-cultural conflicts and misunderstandings. This research will serve as a valuable reference for computer-mediated intercultural communication teaching and open up new possibilities to extend classroom teaching by bridging the gap between second-hand knowledge and hands-on experience.

Using action research to evaluate a nursing orientation program in a multicultural acute healthcare setting

Objectives:Competence motivates newly employed nurses to provide high-quality care,which leads to appropriate patient care and satisfaction.A nursing orientation program can have a positive impact on new nurses who are joining healthcare organizations.The research examined the orientation program for new nurses in a multicultural setting to redesign the program.Methods:The study was carried out in a multicultural tertiary setting.Action research was used as a research strategy with qualitative content analysis and quantitative evaluation.Seventy nurses were part of the orientation program.The competence of the nurses was assessed using the Nurse Competence Scale.Focus-group discussions were also conducted to find the views of the beneficiaries about the program.Results:The study revealed that the overall competence was high,and there was an overall gain in the competence score(5.48%)among the nurses.Among their competence in different dimensions,new nurses had a maximum gain in competence for the dimension of ensuring quality.However,they showed low competence gain in teaching coaching.The results show that the difference in the overall pre-and post-test scores was statistically significant(P<0.05)in all dimensions except teaching coaching and managing situations,and the program was effective.However,a few challenges were identified in the program.Conclusions:New nurses were found to be competent,and the orientation program had a significant impact on the competence of the nurses.The findings emphasized the need for modification of some content and strategy for future programs.The strategies developed from the findings were presented.This helps hospitals to consider examining specific aspects of the orientation program and redesigning it so it can enrich the experiences of new nurses.

Optimization of air quantity regulation in mine ventilation networks using the improved differential evolution algorithm and critical path method

In mine ventilation networks, the reasonable airflow distribution is very important for the production safety and economy. Three basic problems of the natural, full-controlled and semi-controlled splitting were reviewed in the paper. Aiming at the high difficulty semi-controlled splitting problem, the general nonlinear multi-objectives optimization mathematical model with constraints was established based on the theory of mine ventilation networks. A new algorithm, which combined the improved differential evaluation and the critical path method （CPM） based on the multivariable separate solution strategy, was put forward to search for the global optimal solution more efficiently. In each step of evolution, the feasible solutions of air quantity distribution are firstly produced by the improved differential evolu- tion algorithm, and then the optimal solutions of regulator pressure drop are obtained by the CPM. Through finite steps iterations, the optimal solution can be given. In this new algorithm, the population of feasible solutions were sorted and grouped for enhancing the global search ability and the individuals in general group were randomly initialized for keeping diversity. Meanwhile, the individual neighbor- hood in the fine group which may be closely to the optimal solutions were searched locally and slightly for achieving a balance between global searching and local searching, thus improving the convergence rate. The computer program was developed based on this method. Finally, the two ventilation networks with single-fan and multi-fans were solved. The results show that this algorithm has advantages of high effectiveness, fast convergence, good robustness and flexibility. This computer program could be used to solve lar^e-scale ~eneralized ventilation networks o^timization problem in the future.

Power system stabilizer design using hybrid multi-objective particle swarm optimization with chaos

A novel technique for the optimal tuning of power system stabilizer (PSS) was proposed,by integrating the modified particle swarm optimization (MPSO) with the chaos (MPSOC).Firstly,a modification in the particle swarm optimization (PSO) was made by introducing passive congregation (PC).It helps each swarm member in receiving a multitude of information from other members and thus decreases the possibility of a failed attempt at detection or a meaningless search.Secondly,the MPSO and chaos were hybridized (MPSOC) to improve the global searching capability and prevent the premature convergence due to local minima.The robustness of the proposed PSS tuning technique was verified on a multi-machine power system under different operating conditions.The performance of the proposed MPSOC was compared to the MPSO,PSO and GA through eigenvalue analysis,nonlinear time-domain simulation and statistical tests.Eigenvalue analysis shows acceptable damping of the low-frequency modes and time domain simulations also show that the oscillations of synchronous machines can be rapidly damped for power systems with the proposed PSSs.The results show that the presented algorithm has a faster convergence rate with higher degree of accuracy than the GA,PSO and MPSO.

Numerical Analysis of the High Skew Propeller of an Underwater Vehicle

A numerical analysis based on the boundary element method （BEM） was presented for the hydrodynamic performance of a high skew propeller （HSP） which is employed by an underwater vehicle （UV）. Since UVs operate at two different working conditions （surface and submerged conditions）, the design of such a propeller is a cumbersome task. This is primarily due to the fact that the resistance forces as well as the vessel efficiency under these conditions are significantly different. Therefbre, some factors are necessary for the design of the optimum propeller to utilize the power at the mentioned conditions. The design objectives of the optimum propeller are to obtain the highest possible thrust, minimum torque, and efficiency. In the current study, a 5-bladed HSP was chosen for running the UV. This propeller operated at the stern of the UV hull where the inflow velocity to the propeller was non-uniform. Some parameters of the propeller were predicted based on the UV geometrical hull and operating conditions. The computed results include the pressure distribution and the hydrodynamic characteristics of the HSP in open water conditions, and comparison of these results with those of the experimental data indicates good agreement. The propeller efficiency for both submerged and surface conditions was found to be 67% and 64%, respectively, which compared to conventional propellers is a significantly higher efficiency.

Risk Analysis for Mega Shopping Mall Projects in Egypt

Mega shopping mall projects have seen dramatic growth and great development in recent years in Egypt. Many new mega shopping mall projects are under construction and expecting to start working in the few coming years. In the absence of researches studying the Egyptian mega shopping mall projects, this study tries to highlight the most critical risks that face these projects and the associated most effective response methods to be employed. The scope covers the analysis from different perspectives by including owners/developers, designers, consultants, project managers, and contractors that have previous experience in large-scale projects such as shopping mall projects. In this study, 30 construction project risks are classified into six main categories according to their type and 150 risk mitigation/elimination measures are introduced to overcome the impact of risks under each of these risk categories. The results reveal that the main risk category that faces the mega shopping mall projects in Egypt is the one including the financial risk factors. The most critical risk factor that faces these projects is the financial ability of the client. These results are similar to findings by previous researches conducted for large projects in other countries.

Reading Developmental Trends in Early Years： The Influence of Word Identification Skills and Target Langauge Oral Ability to Comprehension

Language, reading, and reading-related tasks were administered to 148 children from lower primary （Standard 1, 2, and 3） in Kenyan schools. The aim was to investigate the literacy developmental trends across the years and establish which of the two variables, word identification skills or target language oral proficiency influenced reading comprehension performance. The results indicated that word identification skills independently influenced reading comprehension performance in both standard 2 and standard 3 classes, but target language oral skills did not. Further, the analysis of invented spelling task performance revealed evidence of transfer of alphabetic coding skills of first language to English orthography. The spelling errors reflected letter-sound patterns not found in English orthography. Analysis of the miscues in the spelling task revealed that children rely on first language phonological processes to spell target language unfamiliar words as long the languages have a common alphabetic system.

Design and Validation of Leadership Education Integrating Simulation and Project Based Learning

All engineering students need to develop their important skills of leadership in project management. Many students have never been leaders in their social and school lives. A leading role is unimaginable to them and hence they cannot imagine how to achieve it. The purpose of this paper is to report a result of a new leadership education program which links a variety of simulated experiences with real actions of students in project based learning （PBL） to develop their leadership ability. The first step is for graduate students to gain knowledge in the leadership arena. Then, they utilize simulation to experience leadership actions many times. Simulation provides a safe environment in which they can try out many different approaches in taking leadership in various situations. In the next step, students as a team utilize PBL, so that the above simulated experiences can help them to actually take leadership. Students can apply trained leadership to actual projects. It is highly effective to apply conscious leadership to a project aimed at a specific goal in limited circumstances. This education repeats both of the steps above, raising leadership abilities in an upward spiral. In terms of students＇ evaluation of leadership education in project management, 360-degree assessments were carried out by teachers, senior, and junior students before and after the course, and authors compare their assessments thoroughly. As a result, authors are assured that students not only gained knowledge but also raised leadership abilities in their actions after this education. Six months after the time of leadership education employing simulated experiences and PBL, follow-up interviews were conducted on its effects. Authors recognized the cyclic period that students apply simulated experiences to PBL and that they seek different approaches in simulation for solving problems found in reality. This research concludes that this cycle of simulator and PBL can produce effective leadership actions.
