Design and Development of Commuter Services Model in Trains using Cloud
Manne Sai Rakesh,S. Venkatesh Sundarasetty,P. Ramesh Pasupuleti,A. Umamakeswari
Journal of Artificial Intelligence , 2013,
Abstract: The cloud technology is becoming ubiquitous and making the things easier. The idea is to seep this technology into the trains and other transport systems also. Without technology, transport system is more complicated and boring and these can compensated with cloud. A central server on the train, with memory, processing capacity, internet connectivity and with a local network throughout the train (access points in each compartment or use directional antennas) could be of great use to passengers, railway authority and police. The technology improvement goes in hand with the use of clouds on train. With help of Global Positioning System (GPS) and internet, cloud can predict the train clash possibility and alert the concerned authority. This cloud can be used for some of the services like software as a service, infrastructure as a service, etc., and also enjoy on demand services like video streaming, etc., locally. The server can also be used by railway authority for updating the passenger details and know about vacancy of berths and other information which makes it easy for them to know anything at the snap of the finger, even when there is no connectivity between bogies. The cloud can be used to collect the information about the surroundings and give the notifications to the user/whoever is connected to the server.
Development and Installation of High Pressure Boilers for Co-Generation Plant in Sugar Industries  [PDF]
Kolar Seenappa Venkatesh, Aashis S. Roy
Smart Grid and Renewable Energy (SGRE) , 2010, DOI: 10.4236/sgre.2010.11008
Abstract: The sugar cane containing minimum 30% fiber was referred as bagasse and used the generation of power required for the operation of sugar mill. The bagasse is fired in the boiler for producing steam at high pressure, which is extracted through various single high capacity turbines and used in the process. The installation of high pressure boilers and high pressure turbo-generators has provision for the operation of co-generation plant during the off-season also that enhances the power generation from 9MW to 23MW. The annual monetary benefits achieved are Rs. 204.13 million and this was based on cost of power sold to the grid @ Rs 2.548 per unit, sugar season of 219 days and off season of 52 days. This required an investment of Rs 820.6 million. The investment had an attractive simple payback period of 48 months.
Supracutaneous Locking Compression Plate for Grade I & II Compound Fracture Distal Tibia—A Case Series  [PDF]
S. K. Venkatesh Gupta, Shyam Prasad Parimala
Open Journal of Orthopedics (OJO) , 2013, DOI: 10.4236/ojo.2013.32021
Abstract:

Background: Supracutaneous plating using a locking compression plate (LCP) as an external fixator in compound periarticular areas is facilitated by the development of anatomical plates. The soft tissue around the distal tibia is easily compromised by trauma and subsequent operative fracture treatment posing a definitive challenge in the distal tibia compound fractures. The purpose of this report is to describe our successful results using the metaphyseal locking compression plate (LCP) as an external fixator in the treatment of Grade I & II compound fractures of distal tibia. Methodology: A total of five (05) patients underwent “supracutaneous plating” of the tibia using a metaphyseal locking compression plate. Average age was 36 years. Regular screw tract dressings were done. Average period of follow-up was 15 months. Results: The plate was in situ for an average of 24 weeks. There were no clinically significant screw site infections. In all five patients the plate was kept in place until there was complete consolidation both clinically and radiologically. At the latest follow-up (average 15 months), all patients were fully weight bearing with a fully healed tibia. All patients were infection-free with well-healed wounds. Conclusion: Routinely, after initial debridement and temporary bony stabilization is provided by external fixation in compound fractures of the distal tibia with significant soft tissue injury. Most external frames for the lower leg are bulky and cumbersome, causing significant problems for the patient. To circumvent these issues, we have successfully used an anatomically-contoured supracutaneous metaphyseal locking compression plate as external fixator in a series of five patients for grade I & II compound fracture of the distal tibia.

Management of Tibial Metaphyseal Fractures by Hybrid External Fixator  [PDF]
S. K. Venkatesh Gupta, Gottipati Sunil
Open Journal of Orthopedics (OJO) , 2014, DOI: 10.4236/ojo.2014.43014
Abstract: Introduction: The Hybrid External Fixator combines the advantages of the monolateral pin fixators and the circular Ilizarov wire fixators. Principle of early motion has been touted as the functional savior of major intra articular injuries in application of hybrid external fixation. Materials & Methodology: 48 patients were considered for the study with tibial fractures admitted in Mamata General Hospital from May 2011 to May 2013. Results: The union and functional outcome of hybrid external fixator in simple and complex proximal and distal metaphyseal fractures of tibia in adults was evaluated at our centre. The fractures of the proximal tibia united with an average of 13.3 weeks (12 - 16 weeks). The fractures of the distal tibia united with an average of 14.42 weeks (13 - 22 weeks) with minimal complications. Conclusion: Our study shows high satisfaction rate after fixation, provides adequate stability and allows early motion of the joint. It is also effective in extra articular fractures occurring within 5 cm of the joint as the IM nails often do not provide enough stability and plating requires extensive soft tissue dissection.
Is Ultrasound Effective in Diagnosing Internal Derangements of the Knee?  [PDF]
S. K. Venkatesh Gupta, Sugnanam Sirish Aditya
Open Journal of Orthopedics (OJO) , 2013, DOI: 10.4236/ojo.2013.38059
Abstract:

Internal derangement of knee significantly affects daily activities of patients and management of such cases with accurate diagnosis and early treatment is of utmost importance. This study determines the benefits of arthroscopy directly and also compares the sensitivity and specificity of ultrasound, MRI and arthroscopic findings in diagnosing internal derangements of the knee. This is a prospective study of 50 cases that includes patients having knee pain and instability of joint for more than 6 weeks, symptoms of locking of knee joint or effusion and having no bony injury as confirmed by X ray. Results were analysed and sensitivity and specificity were calculated. The present study supports that the clinical diagnosis is of primary necessity, while ultrasound and MRI are additional diagnostic tools in diagnosing IDK. Arthroscopy combines more accurate diagnosing tool and therapeutic modality, which is a more convenient, economical and convincing technique to both surgeon and patient alike. Although ultrasound is less accurate than MRI, it is cost effective and available at most of the peripheral centres. So it is better to do ultrasound rather than MRI for diagnosing IDK in peripheral centres and refer to specialty clinics or tertiary centres for further diagnosis and treatment.

 

A Case Series of Various Swelling of Fingers in Adults  [PDF]
S. K. Venkatesh Gupta, Srujith Kommera
Open Journal of Orthopedics (OJO) , 2014, DOI: 10.4236/ojo.2014.412052
Abstract: Patients commonly present to their general practitioner with swellings of the hand. These include a variety of diagnoses with certain lesions (for example, ganglion) being more common than others. Some may even be familiar as they are often site-specific. This article aims to provide general practitioners with clear and concise information regarding swellings to be ruled out before suspecting giant cell tumor of tendon sheath. Swellings of the hand are commonly encountered in a general practice with different diagnosis. They may arise from any tissue in the hand including skin, subcutaneous fat, muscle, nerves, vessels, tendon, bone and cartilage. Fortunately, most are benign, asymptomatic and may not require surgical intervention. Ganglions, epidermoid inclusion cysts, giant cell tumours of the tendon sheath, and swellings associated with arthropathy comprise the majority of lesion. This study includes 16 cases which are presented with similar history and presentation of finger swellings as that of giant cell tumor tendon sheath but the final diagnosis has varied.
QoS Aware Routing Protocol to Improve Packet Transmission in Shadow-Fading Environment for Mobile Ad Hoc Networks  [PDF]
T. Sangeetha, K. K. Venkatesh Venkatesh, Rajesh  , M. S. K. Manikandan
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53B2110
Abstract:

In Shadow-Fading model, it is difficult to achieve higher Packet Delivery Ratio (PDR) due to the effects of large scale fading. The main goal of this paper is to improve the PDR in Shadow-Fading environment. To achieve this objective a protocol has been proposed that discovers backup routes for active sessions. These backup routes salvage the packets of active session in case of active route failure. It is found by research that proactively maintaining backup routes for ac-tive sessions can noticeably improve the PDR in Shadow-Fading environment. This protocol has been implemented with a mechanism of having backup routes and simulations have been conducted by using both node disjoint paths and link disjoint paths. Comparisons have been made between new protocol as well as AODV protocol. Simulation has been carried out using Network Simulator 2 (NS2) and the results show that the proposed QoSAR protocol exhibits higher PDR than AODV protocol in Shadow-fading environment.

S. Anandamurugan,C. Venkatesh
International Journal of Advances in Engineering and Technology , 2012,
Abstract: Fast growth of wireless services in recent years is an indication that considerable value is placed on wireless networks. Wireless devices have most utility when they can be used anywhere at any time. One of the greatest challenges is limited energy supplies. Therefore, energy management is one of the most challenging problems in wireless networks. In recent years, Wireless Sensor Networks have gained growing attention from both the research community and actual users. As sensor nodes are generally battery-energized devices, so the network lifetime can be widespread to sensible times. Therefore, the crucial issue is to prolong the network lifetime. In this paper, various Energy Efficient Schemes for Wireless Sensor Networks (WSN) has been compared. Many techniques like Aggregation, Scheduling, Polling, Clustering, Efficient node deployment scheme, Voting and efficient searching methods are used to increase the network life time. In the deployment of nodes using Multi Robot deployment of Nodes method, the result shows that the percentage of reduction in energy consumption is 4%. The Aggregation routing method, analysis shows that the percentage of reduction in energy consumption was 21%. The percentage of reduction in energy consumption is 26% in the effective search technique called Increasing ray search method. In the Voting Scheme, the result gives that the percentage of improvement in energy savings is 34%. The improvement in energy saving is 51% in the Polling method. As per the analysis, polling scheme was very much effective in terms of reducing the energy consumption in Wireless Sensor Networks.
