Wireless Engineering and Technology 2011年第3期2卷 212-220页

作者： Kalpana Chaudhari Upena dalal rakesh Jha Department of Electronics Engineering Sardar Vallabhbhai National Institute of Technology

The Information and Communication Technologies play an important role in rural development. The Empowerment of rural communities is crucial for the development of the rural region. Bringing the people in the rural region in the mainstream of the digital technologies to access and adopt modern technologies is a major concern now. Rural Development implies both, the economic development of the people and greater social transformation using electronic governance (e-governance). In order to provide the rural people in Maharashtra with better prospects and opportunities for economic development, agricultural development and management, marketing management, increased participation of rural people in usage and adoption of information and communication technologies (ICTs) is envisaged. This paper aims to explore the nature, role and relevance of the Electronic/Digital Governance using ICTs and wireless technologies for agriculture and rural development in the rural regions. It also aims to study the impact of e-governance on rural development and methods for improving local environmental governance having regard particularly to the range of interests and actors involved in e-governance. The paper examines the current status of electronic governance in Jalgaon district in India. It focuses on development of the model using ICTs/wireless technologies for e-governance of Jalgaon district in Maharashtra state, India.

Properties of filaments in solar cycle 20-23 from McIntosh Archive

引用

Research in Astronomy and Astrophysics 2019年第6期19卷 43-50页

作者： rakesh Mazumder Center of Excellence in Space Sciences India Indian Institute of Science Education and Research Kolkata

A filament is a cool, dense structure suspended in the solar corona. The eruption of a filament is often associated with a coronal mass ejection(CME), which has an adverse effect on space weather. Hence,research on filaments has attracted much attention in the recent past. The tilt angle of active region(AR)magnetic bipoles is a crucial parameter in the context of the solar dynamo, which governs the conversion efficiency of the toroidal magnetic field to poloidal magnetic field. Filaments always form over polarity inversion lines(PILs), so the study of tilt angles for these filaments can provide valuable information about generation of a magnetic field in the Sun. We investigate the tilt angles of filaments and other properties using McIntosh Archive data. We fit a straight line to each filament to estimate its tilt angle. We examine the variation of mean tilt angle with time. The latitude distribution of positive tilt angle filaments and negative tilt angle filaments reveals that there is a dominance of positive tilt angle filaments in the southern hemisphere and negative tilt angle filaments dominate in the northern hemisphere. We study the variation of the mean tilt angle for low and high latitudes separately. Investigations of temporal variation with filament number indicate that total filament number and low latitude filament number vary cyclically, in phase with the solar cycle. There are fewer filaments at high latitudes and they also show a cyclic pattern in temporal variation. We also study the north-south asymmetry of filaments with different latitude criteria.

The present study investigates the vulnerability assessment of the prototype revised Mandatory Rule of Thumb(MRT)buildings initially designed and detailed for three storeys bare frame building;later modified through variable number of storeys(three,four,and five)and different arrangement of infill walls(bare frame,soft-storey,irregular infilled,and fully infilled).The application of infill walls increases the fundamental frequencies,stiffness,and maximum strength capacity,but reduces the deformation capability than the bare frame *** vulnerability was also reduced through infill walls,where the probability of exceeding partial-collapse and collapse damage reduced by 80% and 50%,***,the increased in storeys(three to five)also increases the failure probability,such that partial-collapse and collapse for fully infilled increases by almost 55% and 80%,*** obtained results and discussions concluded that the structural sections and details assigned for MRT building is not sufficient if considered as bare frame and *** increase in number of storeys causes building highly vulnerable although the infill walls were considered.
