Studies in a multidisciplinary optimization frame work have been carried out to show the benefit of span extension for High Altitude Long Endurance (HALE) Unmanned Aerial Vehicles (UAV) in terms of increasing their loiter performance. Various aspects have been considered in a multidisciplinary optimization framework such as extension mechanism weight penalties, wet wing fuel tank capacity reductions, and lift distribution over the wings. These considerations are made in terms of empirical relations to check feasibility and optimum span extension. The purpose of this paper is to generate a detailed design of a wing tip extension mechanism for a HALE UAV. Load estimates that drive the extension mechanism dimensions are discussed. Based on these load values, appropriate mechanism driving toques and powers have been calculated and hence appropriate motor selections have been done. Actual results of the detailed design can be compared to empirical estimates cited in earlier work. The final paper will describe the calculation procedure followed and the detailed results.

Introduction of Electric Vehicles (EVs) as a main means of transport forms a major initiative globally amidst the concerns of continuing availability of conventional fuels, pollution levels and long term sustainability. Providing reliable and assured levels of energy for charging a huge population of EVs is the main challenge to be faced when shifting from conventional fuel based vehicles to EVs. Charging EVs without putting burden on grid is main challenge. This paper presents an assessment of the possible means of providing power to individual EVs along with a comparison of different related aspects. A special case is sought to be made for using fuel cell based system from among the alternatives for structuring a localized power supply system. An exercise in estimating the inputs and the costs involved in creating a plant with 600 Kw systems as an example is presented.

The kidney stone, also known as renal calculus can be identified by Computed Tomography imaging. There are various problems associated with this imaging technique such as blurry image, the low resolution of CT scan image, the similarity of renal calculi with other parts near kidney and prediction of stone in the image of the kidney. Computed Tomography takes X-rays through the required slices from the body. The image first goes through various preprocessing stages, then it is segmented and finally, the number of stones and their respective area are identified to help the doctor to analyze the patient's condition. This study has developed an automatic renal calculi detection system using the digital image processing techniques in CT scan images.

In combustion chambers due to coupling between unsteady heat release and pressure fluctuations the thermoacoustic instabilities are developed. These instabilities create structural vibration and damage. Therefore, there is a need to develop a technique which can effectively control these instabilities. The present work focuses on passive control using Helmholtz Resonator. The Rijke tube setup has been developed for characterization of thermos-acoustic instabilities. The study has been carried out with open-open ended steel Rijke tube of L/D ratio as 1. The preliminary results show that for LPG pre-mixed burner position at $x$/L = 0.2, maximum thermos-acoustic instabilities were observed. The instability of 2nd and 3rd mode at a frequency of 500 Hz and 800 Hz respectively were observed for the different air-fuel ratio. The Helmholtz Resonator was designed and placed at the different position from one of the end. The maximum suppression of thermo-acoustic instabilities was observed at Helmholtz resonator position $x$/L = 0.6. The experimental results show that approximately 10 dB reduction for the 2nd mode of instability was achieved whereas, the Helmholtz Resonator was not effective for 3rd mode as there is a change in heat source location and frequency of instability.

For designing intelligible and natural Text-to-Speech systems (TTS) researchers all over the world are studying relation between prosodic features and emotions in various languages. The objective of this research is to study acoustic correlates between prosodic features including duration, F0 and intensity for vowels and various emotions in Marathi language. Also, these prosodic features are analyzed for vowels in words non-final and final syllables. Pause durations occurring between words for various emotions are also studied. Marathi sentences spoken by a female speaker are recorded in five emotion styles: anger, fear, happy, sadness and neutral. For every sentence vowel mean duration, mean F0 and mean intensity are calculated. Long pauses, mid-pauses and short pauses for all the five emotions are analyzed. The ANOVA analysis for F0 and intensity with p<0.001 indicate that these parameters can be used as cue for various emotion styles for Marathi language. Short vowel duration and large number of short pauses are observed for angry emotion whereas long vowel duration and short, mid and long pauses are observed equally for happy emotion. Above observations related to prosodic features and pauses would be useful to model Marathi TTS system.

The amount of vehicle damage and ride comfort of the passengers is mainly determined by suspension system which plays a major role in automotive vehicle dynamics. Leaf springs are found to be durable and inexpensive. They are good at isolating road incited vibrations and support vertically acting loads. This is the reason that the static and dynamic examination of the leaf spring is exceptionally fundamental to anticipate the quality and vibration properties. Stacking sheets of metal having extensive thickness of various lengths are arranged in a manner by which the more extended leaves are on the top of the shorter leaves banding them together with the assistance of a centre bolt, two U braces and four rebound clips which frames a leaf spring. The behavior of leaf spring is complicated because of its effects caused by the clamps and contact between the leaves. It is inferred from literature that, for the suspension arrangement of the passenger vehicles the excitation frequencies range from 1Hz to 800 Hz because of road irregularities which have to be damped to prevent passenger discomfort. This research work predominantly focuses on the static and modal examination to discover the mode shapes and their individual natural frequencies and validated by the experimental results with the assistance of LMS Test Lab. The modal analysis is done with the same three-dimensional model leaf spring of Maruti Suzuki Omni passenger vehicle using FEA. The design optimization is performed based on finite element analysis which helps in weight reduction by maintaining similar modal behavior and strength. Consequently, the natural behavior of leaf spring is investigated up to 10 mode shapes. The actual behavior of the leaf spring under road irregularities is recreated by road testing. The results obtained are analyzed and compared with standards and suitable damping is suggested to control vibrations.

Mobile Adhoc Network (MANET) are the networks where network nodes uses wireless links to transfer information from one node to another without making use of existing infrastructure. There is no node in the network to control and coordinate establishment of connections between the network nodes. Hence the network nodes performs dual function of both node as well as router. Due to dynamically changing network scenarios, absence of centralization and lack of resources, MANETs have a threat of large number of security attacks. Hence security attacks need to be evaluated in order to find effective methods to avoid or remove them. In this paper malicious behavior of Blackhole attack and Rushing attack is studied and analyzed for QoS metrics.

Enormous size of climate data has posed a difficulty in terms of storage since a long time. Principal Component Analysis is a well known method used for data compression. This paper gives a brief idea about the compression of climate data using Principal Component Analysis by modifying the data obtained from the weather station. A minor modification in handling data led to a high compression ratio. This compressed file can then be processed to retrieve the data again with a significant accuracy. The data obtained from the retrieval using compressed file almost matched the real time data.
