Component Based Development relies on already existing components to develop the system. It offers various advantages as increase in productivity, reduced development effort and time. The biggest challenge is to select the appropriate component from number of alternatives based on the quality parameters. In this paper COTS component selection is reduced to a multi criteria decision problem by quantifying it with PROMETHEE method. PROMETHEE is an outranking method which better supports the evaluation and selection from various alternatives based on the functional and non-functional requirements. The aim of this paper is to show the application of PROMETHEE in evaluating, analysing and selecting the appropriate COTS component with respect to requirements. The paper also discusses the procedure and benefits of using PROMETHEE method over the other MCDA methods.
COTS based development is becoming a popular software development approach for building large organizational software using existing developed components. COTS based approach provides pre-developed components either as in house or commercial off the shelf components, which reduces effort and cost for developing the software. There are potential challenges, risks and complexities in using COTS components. This paper provides an analysis of risks and challenges faced during developing software using CBSD approach. The risks under various phases are identified, categorized and prioritized the risks in various phases of CBSD and provide the mitigation strategy to manage the risks.
At present time data communication is a keyword to our life. It’s a time of IOT revolution. Lots of devices around us communicate with each other or they send data to internet. Some of the popular data communication protocols are like Bluetooth, Zigbee, Infrared, wifi, Wlan etc. In this project a similar type of wireless data communication system is designed. Some of the key factors of data communications systems are wireless, covered distance, data transfer speed, security or encryption etc. In this paper we have proposed a RGB color based data communication system. In this system each device is a transceiver. Each device contains of 16bit RGB color sensing module and RGB led. To transfer data from one device to another transmitting module encode raw data to a 16bit combination. This 16bit combination is transferred to RGB led and the color of this 16bit combination will glow. The receiving module will read this color and decode the color into 16bit data. This data is the raw data which we want to receive from the transmitter.
This paper contains certain considerations on the High-Speed Railway (HSR) Station’s area and its surroundings, as well as the reasons and effects thereof. The complexity and wide range of possible scenarios require a more specific context pertaining to medium-sized cities and a specific location of the station in those cities, i.e., the city centre. From the analysis based on the fieldwork carried out in certain stations in Germany, as well as from the study of their accessibility level, German cases are compared to other examples in Europe, especially to examples in a country in which HSR was implemented at the same time: Spain. It can be concluded that there are material differences on the ways to approach the revitalisation of stations and the urban surroundings thereof in order to take advantage of the building’s renovation project and the reorganisation of the railway environment as an important engine of urban renovation.
Today, the effective inventory management plays an important role in the success of the organizations in the new business environment. It is not clearly possible for the organizations that store hundreds of inventory items to economically design an inventory management policy for each inventory item separately. To have an efficient control of a huge amount of inventory items, traditional approach is to classify the inventory into different groups. Different inventory control policies can then applied to different groups. The well-known ABC classification is simple to understand and easy to use. Moreover, various inventory items may play quite different roles in the business of the organization. Hence, the managers need to classify these items in order to control each inventory category properly based on its importance rating. In this thesis we consider a model of college hostel mess stores items (grocery and vegetables) for inventory management through ABC analysis. This research is composed of the following sections: In the first section, the criteria affecting the evaluation of the inventory control system of the studied mess stores and the priority of each one of them will be identified, in the second section, the priority of each criterion such as cost of item, annual demand for an each item hence find annual consumption cost in each inventory category (A, B, C) is Calculated based on conventional model, in the third section, presents an alternative way of classifying the different productive items of accompanies and this ABC model compares with the classic Pareto classification, which ranks productive items according to their importance in terms of frequency and costs whereas rankings obtained using the classical method are based on information about costs and demand over a period in the past "A-items" that result from this new classification.
The paper focus on the concept of community participation on water scheme without being wholly controlled by the State Water Corporation, rather the communities are empowered to play more active roles in safeguarding and sustaining development programme, emphasising on purpose, decision making, training, operation and maintenance, participation model and benefits, with the aid of SPSS version 21 statistical package. Therefore, the communities are expected to influence and share control over development initiatives, decision and resources that affect them.
Background: Posterior cruciate ligament (PCL) impingement following anterior cruciate ligament (ACL) reconstruction can often lead to post-operative graft instability and loss of knee range of motion. Purpose: The purpose of this study was to evaluate whether drilling a femoral tunnel through an anteromedial portal led to a decreased incidence of ACL-PCL impingement compared to trans-tibial methods during ACL reconstruction. Methods: Eight cadaveric knees were evaluated arthroscopically. Femoral tunnels used for ACL reconstruction were then drilled using both an anteromedial portal technique as well as a trans-tibial technique. Qualitative and quantitative comparisons of each technique’s ability to center a femoral tunnel in a non-PCL impinging position within the native ACL femoral footprint were then recorded. Results: Of eight tunnels drilled through an anteromedial portal, none showed signs of PCL impingement and all were centered in the native ACL footprint. Three tunnels (37.5%) drilled trans-tibially showed signs of potential PCL impingement starting at 90 degrees flexion, and all were displaced superior to the center of the native ACL footprint by an average of 3.25 mm. Conclusion: Femoral tunnels drilled through an anteromedial portal technique were consistently placed in the center of the ACL femoral footprint, and no potential impingement by the PCL was noted. Femoral tunnels drilled trans-tibially had a tendency to displace superiorly and three showed signs of impinging against the lateral border of the PCL.
This study aims to analyze the production efficiency and identify scale properties of shrimp poly-culture farms in Tam Giang-Cau Hai Lagoon, Thua Thien Hue Province, Vietnam by applying Data Envelopment Analysis under inputorientated approach. In addition, the extension Cross Efficiency Method was undertaken to have better ranking of farm performance, to which the comparisons of the uses of inputs between the truly efficient and inefficient farms were made in order to help farms to properly adjust their input combination to optimal level. It is found that if farmers follow the recommendation by this study, the optimization of inputs configuration tends to decrease the total costs of production by 141.85%, and increase the benefit-cost ratio by 58.79%.
Wood polyacrylonitrile composite (WPC) from neem and cork woods were synthesized. The process was carried out through benzoyl peroxide(0.05mol/l) catalyzed impregnation polymerization of acrylonitrile 2mol/l, 4mol/l, 6mol/l into neem and cork woods in benzene medium at 75+-10c.The properties of WPC over untreated wood was evaluated. Loading of PAN into cork woods as ascertained through TGA, DTGA and DTA as well as Scanning Electron Microscopy (SEM) was found to increase the resistance against thermo-oxidation of WPCs in comparison to untreated wood. Themogravimteric analysis (TGA) is one of the techniques used to determine the thermal properties of wood.Wood polyacrylonitrile composite (WPC) from, mango and cork wood was synthesized. The process was carried out through benzoyl peroxide (0.05moll) catalyzed impregnation polymerization of acrylonitrile, 4mol/l, 6moll into cork wood and mango wood in benzene medium at 75+-10c. The properties of WPCs over untreated woods were evaluated in terms of Thermo gravimetric analysis (TGA) in Nitrogen. Thermo gravimetric analysis were improved with impregnation of polyacrylonitrile. Impregnation of polyacrylonitrile (PAN) into, mango, cork woods were confirmed through scanning electron microscope. In the present research effects have been made to develop such polyacrylonitrile impregnated composites in Benzene medium having improved thermal stability for there commercial exploitation for desirable purposes.
