OSM 1.0 - Obstacle Surmounting Mechanism for Mobile Robotic Platform
No full textImprovement of robotics and or robotic movement is a continuing pursuit. The robotic platform should be able to move between areas of interest quickly and safely but there movement is restricted due to unstructured surfaces such as stairs and hurdles which are higher than the radius of the wheels. In this paper a novel Obstacle surmounting mechanism is designed for high performance locomotion over various terrains for mobile robotic platform. Initially, here we have incorporated the proposed mechanism in two wheeled robot with a trailing link. Proposed mechanism for surmounting obstacles utilizes four bar mechanism with such dimensional relations and arrangements that it enables mobile robotic platform for encountering hurdles which are higher than the diameter of the wheel. The actual approach is to encounter the hurdles through single degree of freedom obstacle surmounting mechanism and placing the wheels over the hurdle smoothly. Each wheel is powered by independent motors
Database Marketing: OLD WINE IN A NEW BOTTLE!!!
No full textThe database marketing field is growing day by day.Lots of people have their inboxes filled on a daily basis withemail messages advertising items that they might want to buy.The list is produced by companies who conduct studies and isthen sold to other companies who market yet more businessesproducts. The current availability of on-line direct marketingdatabases provides numerous opportunities for marketingprofessionals to improve their marketing strategies and tactics.Database marketing is as old as the World Wide Web.It is no longer merely a case of shopping for a database oftelephone numbers and cold calling them in the hopes ofcreating a sale. Data base marketing, now a days is being usedas the foundation for developing a market segmentationapproach to identify new prospects and thus providing amechanism for organizing the company's marketing activities.Lifetime value analysis, a concept that plays a major role inCRM, is used to group prospects into 'good', 'better,' and 'best'categories and thus provide an understanding of the likelyresponsiveness of these segments. Emphasis is a new marketing program to appeal to these prospective customers.Many people also see a disadvantage in the database approachof marketing by believing it is too intrusive. Databasemarketing involves large amounts of information aboutcustomers that is used as a basis for future advertising.However, proponents claim there is nothing wrong with usingcompiled information about customers, and deny anyintrusion.This paper, which will be a descriptive one, author ishighlighting the recent trends of database marketing. how itcan be more effective, what are the bottlenecks, in doing thesame. Further the paper will also argue, about the origin andusage of these so called new and efficient efforts
Nonlinear Static and Dynamic Analysis for Assessment of Progressive Collapse Potential in intermediate RC frame structures
No full textThrough accident or act of terrorism, structures may be subject to conditions that could lead to progressive collapse. A large part of common reinforced concrete (RC) structures are designed as intermediate moment resisting frames. In this study, based on the acceptance criteria of the last edition of UFC 4-023-03 document, the influence of some external column removal cases are evaluated by nonlinear procedures in all stories of a regular structure. Nonlinear static and nonlinear dynamic analyses are conducted to estimate the progressive collapse resistance of the building subjected to column failure. Results show that after column removal in top stories, in both nonlinear static and dynamic analysis, the structure hinges exceeds CP level of performance. Compared to dynamic analyses, it is concluded that static analyses are more conservative in the estimation of total number of plastic hinges and shear force in beams
Application of Void Filler method for restoration of structure
No full textIn this paper we deals with method of injectiongrouting which is useful for filling micro and fine cracks instructures. So Many times pressure injected crack lookedfine, but six inches over, a new crack developed. Coring ofthe existing repaired crack could reveal the new crackemanates from, and because of, the partially filled fracture atthe leading edge of the epoxy. Can anyone argue, “The morecomplete the fill, the more permanent the repair� and goodluck with trying to rectify an incomplete crack fill. Even ifthe pressure advocates had a method, epoxy will not stick toepoxy. its back to that basic physics law when it comes tomaterial penetrations, you cant put two things in the sameplace at once. If there is moisture in the pore structure,there is moisture in the pore structure. Nothing will get inunless the moisture is displaced. Pressure applied to thecrack will not do it. The flow and roll of the repair resinalong the interior walls of the fracture may pull some of itout but what happens to the moisture? We have found tha

Pulse densitymodulation technique’s performance evaluated and despite theneed to higher bandwidth in modulator the performance of thismethod is good
AUTONOMOUS DRIVEN CAR
No full textIn order to achieve autonomous operation of a vehiclein urban situations with unpredictable traffic, several real timesystems must interoperate, including environment perceptionplanning and control. In addition a robust vehicle platform withappropriate sensors, computational hardware, networking andsoftware infrastructure is essential

No full textThis paper deals with the summary of theliterature reviewed for the purpose of the doctoral researchon the investigation of lean tools to enhance productivity inmanufacturing sector. The review shows that theimplementation of lean manufacturing techniques promisesto enhance the productivity and Value Stream Mapping is amust-to-be- used tool to identify the root cause of theproblem and the right tool to rectify it
Qualitative Perspective of cohesion and coupling to optimize the refactored code
No full textIn order to improve the design of object orientedsoftware internally, key design principles are to be applied byrefactoring the existing code [1] partially delivering thefulfillment of the concept low coupling and high cohesion withbetter adherence to open closed principle. The open closedprinciple is extended by applying changes in internalstructure without affecting external behavior of objectoriented software. The refactoring technique is useful toadhere to open closed principl
Function Overloading Implementation in C++
No full textIn this article the function overloading in object-oriented programming is elaborated and how they are implemented in C++. The language supports a variety of programming styles. Here we are describing the polymorphism and its types in brief. The main stress is given on the function overloading implementation styles in the language. The polymorphic nature of languages has advantages like that we can add new code without requiring changes to the other classes and interfaces (in Java language) are easily implemented. In this technique, the run-time overhead is also introduced in dynamic binding which increases the execution time of the software. But there are no such types of overheads in this static type of polymorphism because everything is resolved at the time of compile time.

Neural Network Approach to Measure Reliability of Software Modules: A Review
No full textAbstract: - Software reliability is a key part in software quality. It is the ability of the software to perform its specified function under some specific condition. Reliability can be associated with both hardware and software. The hardware reliability can easily be evaluated since hardware get wear out but in case of software it be very difficult. So neural networks have been used for the last few decades in a broad variety of applications reliability of neural network based and made a review.. In this paper we have studied the softwar
