Rail inspection is an important task in railway maintenance. The speed and loads of trains have been increasing greatly in recent years, and these factors inevitably raise the risk of producing rail defects. Mainly the discrete surface defects impact the riding quality and safety of a railway system. However, it is a challenge to inspect such defects in a vision system because of illumination inequality and the variation of reflection property of rail surfaces. This project presents a realtime VIS for discrete surface defects of rail heads. VIS comprises the Image Acquisition Subsystem (IAS) and the image analysis subsystem. IAS acquires gray rail images for the surface of a rail head, and the latter processes rail images and detects possible defects. This paper propose the Local Normalization(LN) method to enhance the distinction between defects and background in a rail image, considering illumination inequality and the variation of reflection property of rail surfaces
A Smart City is the integration of technology into a strategic approach to sustainability. 21st Century has brought with it a new global trend of “sustainable urban development” and this concept adds new dimensions to urbanization which require a quick need to upgrade existing cities. The concept of a smart city is a relatively new one. Throughout the years, with the significant contribution from various technologies like computer science, information technology, remote sensing, advance multimedia world etc, GIS evolved from traditional geographer’s or cartographer’s tool for surveying and planning to a rapidly expanding primary technology for understanding our planet and related geospatial opportunities to foster a sustainable world. This paper describes smart city projects in India and thoroughly explores the existing and extended capability of GIS to include modeling and visualization in order that decision makers will be able to
This paper assesses the net welfare associated with the adoption of Bench Terraces (BT), Contour Bunds (CB), and Napier Grass Strips (NGS) in the Saba Saba sub-catchment of the Upper Tana catchment in Kenya. An agro-economic survey and informal interviews were conducted in the Saba Saba sub-catchment to elicit farm level quantitative data for the Cost Benefit Analysis (CBA). Financial functions in excel were used to analyze the on-site costs and benefits of adopting the identified SWC technologies on farms with crops such as maize, coffee, and tea. In this research CBA was used as a decision tool after the computation of all cost and benefits were valued in local currency to obtain the Net Present Value (NPV) or net welfare. The results show that investment in SWC measures may not be a feasible short-term option from farmers’ perspective. There is, therefore, a strong case for intervention, especially in the initial years where SWC adoption yields negative returns.
Multi-attribute analysis is a useful tool in many economical, managerial, constructional, etc., problems. There is usually some uncertainty involved in all multi-attribute model inputs. The objective of this work is to demonstrate how simulation can be used to reflect fuzzy inputs, which allows more complete interpretation of model results. A case study is used to demonstrate the concept of general contractor choice of on the basis of multiple attributes of efficiency with fuzzy inputs applying COPRAS method. The work has concluded that the COPRAS method is appropriate to use.
Occupational stress is considered to be a main health problem for both individuals and organizations. This study has investigated the measurement of occupational stress among Management Information Systems (MIS) Users in different banks in the Kingdom of Bahrain. Furthermore, to identify their high job stressor factors and increase understanding of the impact of individuals differences in occupational stress. A descriptive, cross sectional survey was performed in five banks. Using quota sampling, MIS users’ from different divisions were asked to complete questionnaires- including demographic data, job stress and stressor factors. Six main stress factors were identified among MIS users banker staff: 1) intrinsic work characteristics (job design); 2) work culture and function; 3) managerial role; 4) career development; 5) relationships at work and 6) home-work interface. A total of 250 self-administrated questionnaires were distributed (hand delivery) to the banks divisions. The overall response rate was 80.8% (202/250) and the result suggested that over a third of MIS users in banks reported that their jobs were highly stressful. The bankers are exposed to high job stressors such as job design (overload, long working hours, deadlines and time pressure, repetitive task and lack of variety, and shortages of staff); and career development (under promotion and working at a level below their level of abilities and skills). However, the result of this research can be applied for improving sources of occupational stress and further, precluding severe stress and concern was expressed that such findings should be considered when delivering stress management programs.

Increasing website traffic is the main motive of SEOs and in order to approach this goal SEO companies in India make every possible effort to render the highest website ranks in search engines.
As the world runs fast, its our duty to run with the world compensating its speed. There is an urge to prove everyone unique. Hence time management play a worthless role in the daily work of a person. At morning it is a herculean task to wake up from the bed. “Let me sleep for some more time” is the first slogan of everyone every morning. But feeling guilty for not waking up in the morning is also encountered in several cases. In this paper we propose a novel “Murderer Algorithm” based automatic waking up system that helps to wake up every morning. The uniqueness of the system is to make the person in the bed to wakeup and get away from the bed. The device employs simple capacitive touch sensor to sense the presence of a person and also a brig
If you thought that your responsibility ends after you’ve purchased your dream car then you are wrong. The responsibility starts then. Maintaining your car is a task you should take up as a daily routine. It is only then that you can do justice to your priced possession.
The welding machine has really made the tough job of welding two different materials easy. Previously, welding two different metals was a Herculean task, and it used to take a lot of time and pressure, but with the modern invention of welding equipment, the task of welding has dramatically changed.
