Out of multiple research issues of VANETs, efficient routing is a major concern. Effective routing is needed because VANETs are applied to critical applications like accident alerts, driver assistance during vague weather. For this reason, a fast vehicle to vehicle communication is required. In this study, a lane based low overhead unicast procedure is proposed particularly for VANETs. The overhead is minimized by omitting the continuous GPS readings and using a novel position estimation scheme. The entire network is designed by using graphs for the comprehension of the problem. The proposed model is described by using Formal Methods. Formal Methods (FM) is one of the novel mathematical techniques used to prove the correctness and consistency of the model. Vienna Development Method-Specification Language (VDM-SL), a FM, is used for the detailed level description of the protocol. The proposed unicast algorithm is then formalized through VDM-SL. Static and dynamic properties, syntax and semantics of the proposed algorithm is verified through VDM-SL Toolbox.","PeriodicalId":203936,"journal":{"name":"2017 Fifth International Conference on Aerospace Science & Engineering (ICASE)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115463906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pump had to be chosen in such a manner that its cost efficiency, determined by the power consumption of the pump, was enhanced as much as possible. The basic construction and working of different types of pumps and their relative advantages and disadvantages were taken into account. Effect of a range of design parameters on performance and efficiency of the centrifugal pump was analysed on the basis of seminal works on the subject. Accordingly, the control, independent and dependent parameters were chosen for this work. The algorithm was developed for calculation of the dependent parameters and data was generated through iterative method by varying the independent parameters one at a time. The data was analysed and the most cost efficient centrifugal pump was chosen out of a wide range of options on the basis of best results. In the process, the pump selection was generalized based on pump parameters governing the performance of the pump using a simplified technique. The achievement is that now any problem having same setup or scenario can be easily dealt with by using the designed work sheet, where one simply has to plug in the values of different parameters. In turn one gets the power input and cost results without solving numerous equations that govern the working of the centrifugal pump as the calculation part is taken care of by the software.","PeriodicalId":203936,"journal":{"name":"2017 Fifth International Conference on Aerospace Science & Engineering (ICASE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126329761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, these are metal alloys and display typical features of metals like resistance, stiffness, and workability etc. The blend of all these properties makes it easy to know why these materials are smart in the grounds of engineering and ascend to a new way of thoughts about the design of mechanical systems. The present study aims to develop Cu-Zn-Al based shape memory alloy by melting route, finding out the transformation temperatures and the development of shape memory effect. The design and methodology approach includes the mixture of test material which is chips of pure Copper (99.9%), Zinc (99%) and Aluminum (85%). All these chips are mixed and melted. Furthermore, the melt was die casted in open air in a capsule shape. X-ray fluorescence (XRF) was carried out to check the estimated composition and afterwards spectroscopy was done to check the actual composition of the alloy. In addition, the alloy, in a capsule form, was cold rolled up to 1 mm thickness with inter pass annealing at 350°C to form a wire. After that the thermal properties of the wire were examined by a custom made experiment following the principles of Differential Scanning Calorimeter (DSC). The final wire was then heat treated 830C° for 18 minutes followed by step quenching and then aging at 150C° for 90 minutes followed by quenching to induce the shape memory effect (SME) in the alloy.","PeriodicalId":203936,"journal":{"name":"2017 Fifth International Conference on Aerospace Science & Engineering (ICASE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129124241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Undergraduate students are used to develop the mathematical models of such classic control problems. In this project we theoretically design the PID controller and implement it on a very cheap and cost effective hardware. PID controller for this project is a dedicated design and implementation of a system which balances a ball at a particular point on a beam using a PID controller. The ball is free to move on the beam in any direction due to force of gravity. Here, the PID controller set the angle of the beam to make sure that the ball gets stable at our specified set point by eradicating the error between the current position and the reference point. The whole system could be implement by employing a servo motor, an ultrasonic distance sensor, a microcontroller and a support assembly. We used “MATLAB R2013a” to draw the theoretical response of multiple controller and “Arduino 1.6.8” to draw the real time response of ball & beam setup. This system is prior edge towards correlating our theoretical concepts with real time experimental environment and helps towards sophisticated system in grasping and development.","PeriodicalId":203936,"journal":{"name":"2017 Fifth International Conference on Aerospace Science & Engineering (ICASE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128344617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Like all Electromagnetic signals, the GPS signals are also affected by the interferences. Usually the general purpose GPS receivers has the accuracy of 10 ∼ 20 meters. However, the evolution of Real Time Kinematics (RTK) resolved the problem to millimeter accuracy by employing the double differenced carrier phase measurements. RTK positioning is very popular because it provides a precise and efficient way of differential positioning. RTK technique is based on the ambiguity resolution, which is so far the most intricate part. Long initialization time and cycle slips during operation is the main drawback of this technique which increases under obstructive environmental conditions, like power outage due to tree cover and strong multipath in urban canyon. As RTK is a differential technique which uses a base station at a known location and moving rover. The distance between the rover and base station receivers directly affects the accuracy. However, at Zero Baseline which uses the same antenna for the base station and receiver, thus having same environmental effects, provides a trivial but the best possible scenario and all real life uses are more challenged than this. This paper discusses an empirical analysis of the technique during the high environmental effects on the system (Base + Rover) by employing a Zero Baseline condition. The result of the zero base line tests gives an upper bound to the accuracy of the system in any environment. To measure the accuracy, the setup was taken to the varying environmental conditions in the field and their outputs were analyzed using RTK technique.","PeriodicalId":203936,"journal":{"name":"2017 Fifth International Conference on Aerospace Science & Engineering (ICASE)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132912725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In MIMO radar system, linearly independent waveforms are transmitted using different propagation paths via multiple antennas. The waveforms reflected from different targets are also linearly independent with each other which allows to apply the several well-known robust adaptive algorithms to achieve high resolution and interference rejection. These algorithms reject the external interferences as well as accurately estimate the target location and amplitude. Before the advent of digital hardware, the beamformers were implemented using mechanical systems. Today, field programmable gate array (FPGA) has become powerful enough to perform the massive number of operations. FPGA is also a reconfigurable digital hardware which and can reuse for different applications. In this paper, authors investigate the Robust Capon Beamformer (RCB), Doubly Constrained Robust Capon Beamformer (DCRCB) in reconfigurable medium FPGA for MIMO radar systems. The hardware implementation deals with the complex 32-bit single precision floating point values in Virtex5 FPGA at 180 MHz clock. This realization takes input from 10 channels and computes the adaptive weight vector.
