Enhancing automatic control learning through Arduino-based projects     

Hanafy M. Omar 《European Journal of Engineering Education》2018,43(5):652-663

Systems dynamics and automatic control is classified as one of the toughest courses in the college of engineering at Qassim University according to the statistical analysis of the final grades. This motivated us to think about a new approach to teach this course by extending the design term project to include experimental part beside the theoretical analysis. This approach has become feasible due to the publicity of the low-cost microcontrollers such as the Arduino in the recent years. In this paper, we present our experience in conducting Arduino-based projects and how we used them to support the teaching of all the automatic control subjects in the course such as the mathematical modelling, the stability analysis, the controller design and the implementation of the PID controller. It was found that the new approach improves the attention and the overall performance of the students in the course which was reflected in the students’ marks in the quizzes and exams. Moreover, it motivated the students to be creative by utilising the control theory to design new systems that can be useful for their local community.  相似文献

Knowledge heterogeneity and social network analysis – Towards conceptual and measurement clarifications     

Mohamed El?LouadiEmail author 《知识管理研究与实践》2008,6(3):199-213

This literature review highlights some Social Network Analysis (SNA) concepts applicable to the study of organizational knowledge and, more particularly, to knowledge heterogeneity. Knowledge being all at the same time decentralized and distributed, knowing up to what point knowledge can be heterogeneous or homogeneous across organizational units becomes as important as the question of knowing how to structure the organization. SNA applied to knowledge management thus seems a stimulant for future research in the fields of management.  相似文献   

Systemic Change in Vocational Training Institutions in France     

Abbas Moallem  Mahnaz Moallem 《International Journal of Disability, Development & Education》1998,45(1):17-33

The Specialised Vocational Training Institutions (IMPro) in France have recently entered into a difficult, but important period of time. During the past few years, IMPro have faced increasing demand from the public and government to provide quality service to adolescents with intellectual disabilities. IMPro have been also faced with the challenge of being accountable for the low employment rate of adolescents with intellectual disability and their failure to obtain and/or maintain jobs due to lack of technical and social skills. The purpose of the present work was to respond to the increasing and urgent needs in IMPro by designing and developing a training system to enhance organisational productivity, increase employment rate, and eliminate the problems faced by workers with intellectual disabilities. This article describes the process of organisational changes in IMPro using systems thinking. It discusses the model, methods, tools, and techniques used in designing, developing, implementing, and evaluating the new system of training in IMPro in an attempt to improve the quality, effectiveness, and efficiency of their training programs.  相似文献   

“To be or not to be”: the double consciousness of the Tamil Muslims during the early 20th century     

Yunush Ahamed Mohamed Sherif 《Inter-Asia Cultural Studies》2016,17(2):316-323

When the nation building process was gaining momentum during the early 20th century, all the communities in British India had to participate in the process and the Muslims were no exception. Although the Muslim community in British India was as diverse as any other community, there was an attempt to unite its members under the identity of “Muslims” during the first half of the 20th century. But the Tamil Muslims remained aloof from the idea of an “Indian Muslim Community.” They had a double consciousness of being a Tamil as well as a Muslim. They highlighted their “Tamilness” more than their “Muslimness.” More than the Muslim League, their involvement with the Dravidian Movement was substantial. They supported both the movement for Dravidasthan as well as Pakistan. This paper will look into the process of “nation making,” particularly a “Muslim nation” and the anxiety of the Tamil Muslims during these processes. It will analyse the reasons behind the Tamil Muslims being alienated from the other Muslims, the British colonialist denying the identity of “pure” Muslims to the Tamil Muslims and their involvement in the Dravidian Movement.  相似文献

A diagnostic dilemma in Jordan: two child abuse case studies     

H Nazer  T Daradkeh  S Mohamed  A Q Shamayleh  O Marei 《Child abuse & neglect》1988,12(4):593-599

Child abuse was diagnosed in two Jordanian children. The first was a 15-month-old female infant admitted with a history of convulsions and loss of consciousness. The child had previous head and limb injuries resulting in bilateral subdural hematomas and fractures at different stages of healing of femur and pelvis. The second was a 3-year-old male admitted with history of head injury due to an alleged fall. Examination revealed fractured ribs, bruised eye and face, hemothorax, subperiosteal and subdural hematomas. Both children have sustained physical and mental handicaps. This is the first report of child abuse in Jordan. In Jordan, as in the rest of the world, a high index of suspicion is needed to diagnose child abuse early enough to save the affected child its serious sequelae.  相似文献   

Mitigating the urban–rural educational gap in developing countries through mobile technology-supported learning     

Sharifullah Khan  Gwo-Jen Hwang  Muhammad Azeem Abbas  Arshia Rehman 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(2):735-749

One form of educational inequality is the disparity that exists between urban and rural settings. Equal distribution of quality education is a challenge for developing countries due to the unavailability of resources. Various approaches to equal distribution are distance learning, telecast learning and e-learning; however, these approaches cannot achieve the desired objectives due to their limitations. This research aimed to investigate the interesting question of whether mobile technology can bring urban and rural settings closer together. A mobile application for learning Urdu grammar was designed to measure the learning gains of fourth-grade students at two different schools from urban and rural settings. A quantitative technique, the quasi-experimental pre-test and post-test method, was used to measure the effectiveness of the mobile application. The comparison of the students’ performances at the urban and rural schools illustrated the role of mobile technology in mitigating the educational gap. The present study provides evidence that children from different social backgrounds may benefit equally from mobile technology.  相似文献   

Problems of drinking water treatment along Ismailia Canal Province, Egypt     

Geriesh MH  Balke KD  El-Rayes AE 《Journal of Zhejiang University. Science. B》2008,9(3):232-242

The present drinking water purification system in Egypt Uses surface water as a raw water supply without a pre-liminary filtration process.On the other hand,chlorine gas iS added as a disinfectant agent in two steps,pre- and post.chlorination.Due to these reasons most of water treatment plants suffer low fltering effectiveness and produce the trihalomethane (THM) species as a chlorination by-product.The Ismailia Canal represents the most distal downstream of the main Nile Rivet.ThUS its water contains all the proceeded pollutants discharged into the Nile.In addition.the downstream reaches of the canal act as an agricultural drain during the closing period of the High Dam gates in January and February every year.Moreover,the wide in-dustrial zone along the upstream course of the carlal enriches the canal water with high concentrations of heavy metals.The obtained results indicate that the canal gains up to 24.06×106m3 of water from the surrounding shallow aquifer during the closing period ofthe High Dam gates,while during the rest ofthe year,the callal acts as an influent stream losing about 99.6×106m3 of its water budget.The reduction oftotaI organic carbon(TOC) and suspended particulate mattes(SPMs)should be one of the central goals of any treatment plan to avoid the disinfectants by-products.The combination of sedimentation basins.gravel pre-filtration and slow sand filtration,and underground passage with microbiological oxidation-reduction and adsorption criteria showed good removal of parasites and bacteria and complete elimination of TOC.SPM and heavy metals.Moreover,it reduces the use of disinfectants chemicals and lowers the treatment costs.However,this purification system under the arid climate prevailing in Egypt should be tested and modified prior to application.  相似文献
