Adaptive Optimal Control of Space Tether System for Payload Capture via Policy Iteration

The libration control problem of space tether system(STS)for post-capture of payload is studied.The process of payload capture will cause tether swing and deviation from the nominal position,resulting in the failure of capture mission.Due to unknown inertial parameters after capturing the payload,an adaptive optimal control based on policy iteration is developed to stabilize the uncertain dynamic system in the post-capture phase.By introducing integral reinforcement learning(IRL)scheme,the algebraic Riccati equation(ARE)can be online solved without known dynamics.To avoid computational burden from iteration equations,the online implementation of policy iteration algorithm is provided by the least-squares solution method.Finally,the effectiveness of the algorithm is validated by numerical simulations.

A composite particle swarm algorithm for global optimization of multimodal functions

During the last decade, many variants of the original particle swarm optimization （PSO） algorithm have been proposed for global numerical optimization, hut they usually face many challenges such as low solution quality and slow convergence speed on multimodal function optimization. A composite particle swarm optimization （CPSO） for solving these difficulties is presented, in which a novel learning strategy plus an assisted search mechanism framework is used. Instead of simple learning strategy of the original PSO, the proposed CPSO combines one particle＇s historical best information and the global best information into one learning exemplar to guide the particle movement. The proposed learning strategy can reserve the original search information and lead to faster convergence speed. The proposed assisted search mechanism is designed to look for the global optimum. Search direction of particles can be greatly changed by this mechanism so that the algorithm has a large chance to escape from local optima. In order to make the assisted search mechanism more efficient and the algorithm more reliable, the executive probability of the assisted search mechanism is adjusted by the feedback of the improvement degree of optimal value after each iteration. According to the result of numerical experiments on multimodal benchmark functions such as Schwefel, Rastrigin, Ackley and Griewank both with and without coordinate rotation, the proposed CPSO offers faster convergence speed, higher quality solution and stronger robustness than other variants of PSO.

The optimal strategy of the college English teaching is the combination of the language teaching and the knowledge teaching

The requirements of the college English curriculum teaching put forward the teaching objectives to cultivate the English comprehensive application abilities of the students, and improve their cultural qualities and their abilities of the independent learning, which pointed out the direction for the reform of the college English teaching. The language teaching mode based on the contents of the subject advocates that the knowledge learning and the language learning with the combination of the contents of the discipline, to develop the students＇ independent learning abilities, is a feasible and effective way to achieve the goal of the college English teaching. To cultivate the students＇ practical ability of using English is the basic task of the English teaching and learning. But China＇s current college English education failed to organically and effectively combine the teaching of the language knowledge and the cultivation of the language abilities and the teaching of the knowledge, leading to the existence of the obvious price scissors in the students＇ language knowledge and the language abilities. Therefore, the key to the reform of the college English teaching is to correctly position the roles of the foreign language teachers, change the classroom teaching into the process of the two-way interaction between the teachers and the students, focus on the cultivation of the students＇ intercultural communicative competence, so that the students＇ language knowledge and their language abilities can promote each other, and obtain the coordinative development, to better adapt to the requirements of the times.

Exploring English Language Learning Policies in Iran Based on Secondary School Course Books for Learning English in Light of Globalization and Culture

With the globalization of English, the macro and micro cultures of the users of English around the world interact intensively. Considering these conditions, the local and global cultural interface seems an important issue which needs to be clarified in the materials and books used for learning English. Thus, the focus of this study was to explore the language learning policy of the new Iranian English course book at high schools, Prospect 1, recently published and taught for a year in Iran, in light of globalization and culture. This qualitative study was conducted through carrying out semi-structured interviews. The participants of this study were 30 teachers of Ministry of Education, who had the experience of teaching Prospect I for a year and they were mostly chosen from Mashhad and the rest from other cities of Khorasan province, Iran. The interview contained four main questions which were posed to the teachers. The findings of the study indicate that the language learning policy of Iran need to pay more attention to the learners＇ intercultural communicative competence because it mainly attempts at teaching English language focusing on the home culture in the Iranian context. The article ends with some pedagogical implications and more recommendations for developing research studies.

Multi-species particle swarms optimization based on orthogonal learning and its application for optimal design of a butterfly-shaped patch antenna

A new multi-species particle swarm optimization with a two-level hierarchical topology and the orthogonal learning strategy(OMSPSO) is proposed, which enhances the global search ability of particles and increases their convergence rates. The numerical results on 10 benchmark functions demonstrated the effectiveness of our proposed algorithm. Then, the proposed algorithm is presented to design a butterfly-shaped microstrip patch antenna. Combined with the HFSS solver, a butterfly-shaped patch antenna with a bandwidth of about 40.1% is designed by using the proposed OMSPSO. The return loss of the butterfly-shaped antenna is greater than 10 d B between 4.15 and 6.36 GHz. The antenna can serve simultaneously for the high-speed wireless computer networks(5.15–5.35 GHz) and the RFID systems(5.8 GHz).

From Learning English to Learning in English:A Comparative Study of the Impact of Learning Contexts upon Chinese EFL Learners' Strategy Use

The past three decades have witnessed a proliferation of research on Chinese English as a foreign language （EFL） learners＇ use of learning strategies, but little has been examined about the potential influence of learning contexts upon their strategic engagement. This paper reports on the findings of an investigation of the impact of learning contexts upon the use of learning strategies of two cohorts of EFL learners in China. Both cohorts were non-English majors, one from a university where English is the medium of instruction （EMI） and the other from an EFL university. The data were collected using questionnaires and semi-structured interviews. Results reveal that learners from the EMI university demonstrated a higher level in their overall use of learning strategies over their counterparts from the EFL university. Independent T-test shows that the two cohorts were significantly different in their use of cognitive, meta-cognitive, affective and social strategies. These findings were discussed from a socio-cultural perspective. Implications are presented for the reform of English language education in China and beyond.

Life in extreme environments: Approaches to study life-environment co-evolutionary strategies

The term ＂extreme environments＂ describes the conditions that deviate from what mesophilic cells can tolerate. These condi- tions are ＂extreme＂ in the eye of mankind, but they may be suitable or even essential living conditions for most microorgan- isms. Hypertherrnophilic microorganisms form a branch at the root of the phylogenetic tree, indicating that early life originated from extreme environments similar to that of modern deep-sea hydrothermal vents, which are characterized by high-tempera- ture and oxygen-limiting conditions. During the inevitable cooling and gradual oxidation process on Earth, microorganisms developed similar mechanisms of adaptation. By studying modem extremophiles, we may be able to decode the mysterious history of their genomic evolution and to reconstruct e~,rly life. Because life itself is a process of energy uptake to maintain a dissipative structure that is not in thermodynamic equilibrium, the energy metabolism of microorganisms determines the path- way of evolution, the structure of an ecosystem, and the physiology of cells. ＂Following energy＂ is an essential approach to understand the boundaries of life and to search for life beyond Earth.

LANGUAGE LEARNING STRATEGIES AND LANGUAGE ACHIEVEMENT: ACROSS-CULTURAL STUDY

This study explored the relationship between LLS and LA in two different cultural contexts. The findings revealed that the differences between Australian and Chinese university students tend to lie more in their language proficiency levels than in cultural factors. This study also compares learners' strategy use and its relationship to LA in two different educational systems. It is evident that the difference in teaching methods, learning tasks and achievement assessments would have an impact upon learners' strategy use and its relationship to LA.
