A magnetic pulsed launcher (MPL) system is a method for launching a projectile in a smooth linear motion. It applies the basic theories of electromagnetism and circuit theory. This MPL system is basically divided into two categories, one using a coil launcher and the other an induction launcher. In this paper, a small scale MPL system is developed based on the coil launcher technology. A small capacitor (330 muF, 400 V) and a single coil (16 mH) are used in the design whereas the reviewed paper uses a big capacitor and multiple coils. Experiments and simulations have been done to compare and study the relationship between voltage, capacitance, and projectile initial position for optimization of the system. An algorithm is designed based on the experimental data and it is used to optimize the MPL efficiency by changing the value of voltage, capacitance, and projectile position. The MPL have a highest efficiency of 10.05% at 1 cm projectile position when it is supplied with 286 muF, 680.2 V capacitor banks for horizontal motion while 2.55% for vertical motion. The projectile have a highest speed of 23.07 ms-1 for horizontal motion while 11.62 ms-1 for vertical motion.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131994944","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}

To control weed, different weed type would require different herbicide formulation. Consequently the weed must be identified and classified accordingly. In this work, weed images were classified as either broad or narrow weed type. A fundamental problem in weed image recognition using planar curve analysis is to detect curve. It is difficult to successfully extract curve from the image of weed edges since the appropriate scale to use for extraction is not known a priori. As such, this paper considers a curve detection method based on the quadratic polynomial technique which include the use of the region-of- interests (ROI) technique. The ROI technique creates image subsets by selecting regions of the displayed image. The ROIs are typically used to extract statistics for image operations such as classification. As such, the objective of this paper is to present a novel application of curve detection feature extraction technique in weed classification.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134349389","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 infra-red LEDs which emits IR lights is captured by the CCD and is used as the reference. In this system the absolute positioning and orientation were made with the help of a PosEye. The PosEye is normally fixed on a robot arm or the object which requires orientation of its own position in correspondence to its reference points in the working area. This paper discusses general ideas about reference markers, set-up procedures, and issues behind the sensor. This mainly includes the principles of PosEye sensor, basics of vision and cameras. The paper details the experiments in which results were obtained through the PosEye system with the help of electronics and PosEye camera. In the experimental setup, the connection of PosEye with the electronic application is presented, the usage of PosEye and the robot control system communication with the PosEye system using coordinate system. The working of the PosEye system is observed by taking images on the reference plate and finding the co-ordinates (x, y, z). The manipulation of the obtained images to the robot for a movement is also studied.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133812244","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 growth of cellular users' increase every year world wide. GSM as the second generation still exist as the famous technology and soon the third generation comes as a competitor. This technology has delivered an opportunity to communicate to anyone, anywhere and anytime wherever the service is available. In terms of services, many network operators have expanded the service coverage to cope with the increased of user density in a certain service area and improved services to enhance quality of service. In this paper, three control mobility schemes of user movement using a certain threshold level are proposed to investigate user mobility behavior. Each of these schemes incorporates equal cell size and examines in similar mobile environment based random mobility model. Every user can move in any direction with equal probability. Based on hexagonal cell model, 49 cells have been developed as a service area for simulation environment. Two mobility characteristics: user distribution and direction are considered as parameters to analyze user behavior in the certain service area. Simulation results using three mobility control schemes: scheme A, scheme B and scheme C; have shown that in time domain analysis. Result shows that the direction of each MS for any implemented scheme is unique. In term of mobility characteristic, we find that 90% of service area are occupied by MS for both balanced and un-balanced strategies while in cell strategy approach the distribution for all the schemes the result is less that the above strategies in terms of service.","PeriodicalId":443652,"journal":{"name":"2007 5th Student Conference on Research and Development","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115328477","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}
