DESIGN AND FABRICATION OF MAGLEV WIND TURBINE

Abhishek Ghare, Abhishek Patil, Bhushan Padgal, Akshay Palve, JS Patil
2017 International Journal of Advanced Research  
The traditional wind turbine need very high structures to allow room for their massive blades, hence Maglev Turbines are an ideal solution. It is estimated that renewable sources might contribute about 20%-50% to energy consumption in the later part of the 21st century. Maglev wind turbines have several advantages over conventional wind turbines. For instance, they're able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, they could operate in winds exceeding 40
more » ... At present the largest conventional wind turbines in the world produce only five megawatts of power. However, one large maglev wind turbine could generate one GW of clean power, enough to supply energy to 750,000 homes. The paper aims to make a systematic analysis of design and fabrication processes to find out optimum output from the Vertical Axis Maglev Wind Turbine and by also using solar panel for using the solar energy to generate electricity. Copy Right, IJAR, 2017,. All rights reserved. ...................................................................................................................... Introduction:- Combining latest MagLev technology with PV (Solar) panels gives the best of both worlds for greater independence from costly grid electricity bills. From apartments to street lighting, hybrid systems are starting to bring consistent power to areas worldwide, MagLev turbines are an ideal solution to the traditional wind turbine, which need very high structures to allow room for their massive blades. MagLev technology (so called due to the 'magnetic levitation' friction free drive) has been around for a while as we know from the Magnetic Levitation high speed trains. Using MagLev technology in VAWT's (Vertical Axis Wind Turbine) means less moving parts, less maintenance, smaller profile and most importantly, very little wind to start working due to the lack of friction. Objective of Maglev:-1. Design of a new method of generation of electricity using the wind energy generated by the moving vehicles on the highways, roads, etc. 2. Incorporation of more renewable energy to the power system. 3. Development Stand-alone system for providing the power to the highways. 4. Combination of the two natural powers to make desired output. Wind Power:- Wind is known to be another form of solar energy because it comes about as a result of uneven heating of the atmosphere by the sun coupled with the abstract topography of the earth's surface. With wind turbines, two categories of winds are relevant to their applications, namely local winds and planetary winds.

In this paper we have developed a system for visually impaired people using OCR and machine learning. Optical Character Recognition is an automated data entry tool. To convert handwritten, typed or printed text into data that can be edited on a computer, OCR software is used. The paper documents are scanned on simple systems with an image scanner. Then, the OCR program looks at the image and compares letter shapes to stored letter images. OCR in English has evolved over the course of half a

This may not be the case for Indian languages, as they are much more complex in structure and computation compared to English. Therefore, creating an OCR that can execute Indian languages as suitably as it does for English becomes a must. Devanagari is one of the Indian languages spoken by more than 70% of people in Maharashtra, so some attention should be given to studying ancient scripts and literature. The main goal is to develop a Devanagari character recognition system that can be implemented in the Devanagari script to recognize different characters, as well as some words.

Bluebot: Asset tracking via robotic location crawling

Abhishek Patil, Jonathan Munson, David Wood, Alan Cole
2008 Computer Communications  
Asset tracking -knowing what you have and where it is located -is essential for the smooth operation of many enterprises. From manufacturers, distributors, and retailers of consumer goods, to government departments, enterprises of all kinds are gearing up to use RFID technology to increase the visibility of goods and assets within their supply chain and on their premises. However, RFID technology alone lacks the capability to track the location of items once they are moved within a facility.
more » ... s paper presents a prototype automatic location sensing system that combines RFID technology and off-the-shelf Wi-Fi based continuous positioning technology for asset tracking in indoor environments. The system employs a robot, with an attached RFID reader, which periodically crawls the space, associating items it detects with its own location determined with the Wi-Fi positioning system. We propose three algorithms that combine the detected tag's reading with previous samples to compute its location. Our experiments have shown that our positioning algorithms can bring a two to three fold improvement on the raw accuracy provided by the positioning technology.

Finite Projective Geometry based Fast, Conflict-free Parallel Matrix Computations [article]

Shreeniwas Sapre, Hrishikesh Sharma, Abhishek Patil, B. S. Adiga and Sachin Patkar
2011 arXiv   pre-print
Matrix computations, especially iterative PDE solving (and the sparse matrix vector multiplication subproblem within) using conjugate gradient algorithm, and LU/Cholesky decomposition for solving system of linear equations, form the kernel of many applications, such as circuit simulators, computational fluid dynamics or structural analysis etc. The problem of designing approaches for parallelizing these computations, to get good speedups as much as possible as per Amdahl's law, has been

For the problem of conjugate gradient algorithm, the approach looks at an alternative data distribution based on projective-geometry concepts. It is proved that this data distribution is an optimal data distribution for scheduling the main problem of dense matrix-vector multiplication. For the problem of parallel LU/Cholesky decomposition of general matrices, the approach is motivated by the recently published scheme for interconnects of distributed systems, perfect difference networks. We find that projective-geometry based graphs indeed offer an exciting way of parallelizing these computations, and in fact many others. Moreover, their applications ranges from architectural ones (interconnect choice) to algorithmic ones (data distributions).

2021 bioRxiv   pre-print
Plant invasions pose an unprecedented threat to biodiversity and ecosystems at different spatial scales, especially for a biodiversity-rich developing nation like India. While country-level checklists are considered as the first step for effective management of plant invasions, databases having biological and ecological attributes of these plant species are of paramount importance for facilitating research activities and developing policy interventions concerning alien plant invasion in a

Though checklists with the names and basic details of alien plant species are available for India, a database aggregating attributes relevant to the understanding of the invasion continuum is lacking. We have curated data for 13 variables related to ecology, biogeography, introduction history, socio-economy and environmental niche of 1747 alien vascular plant species from 22 national and global sources to produce the Indian Alien Flora Information (ILORA) version 1.0 database. This paper describes the detailed methodology of curating these data along with the logic behind selecting these variables to be included in the database. The database, first of its kind for the Indian alien flora, will provide easy access to high quality data, offer a ready reference to comprehend the existing scenario of alien plant species in the country and provide opportunities to identify, scrutinize and prioritize the management of these species. The database is dynamic and will be continuously updated with the availability of new data. It has the provision for bidirectional information exchange with the users, which will allow increasing the resolution of the database as well as the expansion of its capacity. All data will be associated with the source information and ILORA will encourage users to refer to the primary sources to give the contributors full credit and acknowledgement. The database is, therefore, envisaged to become a nationwide collaborative platform for a wide spectrum of stakeholders involving the scientific community, citizens, and policymakers. ILORA is freely accessible via an online data repository as well as through a dedicated website (https://ilora2020.wixsite.com/ilora2020).
