Animal Tracking Telemetry Circuit using Low Power FM Transmitter
Get PDFThere are many rare animals in every countries. Like here in Bangladesh Royal Bengal Tiger is one of them. They need to be protected from being disappeared. Detail information such as their number or their location is also necessary to be collected as they are our national resource. So in this project, a wireless telemetry circuit for animal tracking will be designed, built and tested. The project includes a tone generator, a Low power FM transmitter, and a Spectrum Analyzer. The purpose is to help scientist track and locate animals by sending and receiving radio wave pulses from the FM Transmitter attached to the animal
A New Method to Measure the Job Satisfaction Level of an Employee
Get PDFJob satisfaction can simply be defined as the feelings people have about their jobs. As most people spend a major part of their adult life at work, job satisfaction is an important element of individual wellbeing. Employers always try to maintain high level job satisfactions of their employees to get best services of them, because job satisfaction inspires the workforce to work honestly and efficiently. There are many factors which play vital role in the job satisfaction of an employee. We summarize them by five factors namely payment, supervision, promotion opportunities, environment of the workplace and the work itself. Using these facets, we establish a new method to measure job satisfaction level of an employee in percentage. We illustrate our method with the help of an example
Machine Learning and Artificial Intelligence in Online Fake Transaction Alerting
Get PDFArtificial Intelligence (AI) is one of the most promising and intriguing innovations of modernity. Its potential is virtually unlimited, from smart music selection in personal gadgets to intelligent analysis of big data and real-time fraud detection and aversion. At the core of the AI philosophy lies an assumption that once a computer system is provided with enough data, it can learn based on that input. The more data is provided, the more sophisticated its learning ability becomes. This feature has acquired the name "machine learning" (ML). The opportunities explored with ML are plentiful today, and one of them is an ability to set up an evolving security system learning from the past cyber-fraud experiences and developing more rigorous fraud detection mechanisms. Read on to learn more about ML, the types and magnitude of fraud evidenced in modern banking, e-commerce, and healthcare, and how ML has become an innovative, timely, and efficient fraud prevention technology
Digital India with E-Commerce Revolution in Rural India: Transform India Digitally and Economically
Get PDFThe E-Commerce is prospered and stands for booming growth in Rural India. Their success depends on the understanding of the market, quantity of consumers and offering various features. This paper gives an impact of digital India in the future of E-Commerce in Rural India; represent the various opportunities for vendors, consumers, E-Commerce Industries and factors influencing trust in rural Indians. We found that the Overall E-Commerce will increase drastically coming years in the emerging market. While rural area availability of internet or broadband is lower as compare to urban area but Government’s dream project Digital India will control or fixed this gap which increases the mass of consumers for E-Commerce world through spreading business using social commerce (Facebook Commerce, Twitter Commerce), mobile commerce etc. with adopting Digital India project features like creation of digital infrastructure and digital literacy. Combination of E-Commerce and Digital India project make easier contact can be made to anywhere in the world in seconds. By online trading, businesses open themselves in global marketplace. Indians should call Digital India Vision or Digital Bharat Vision or Digital Hindustan Vision projects moving forward. This paper is concerned with current scenario of internet users in India, how government campaign “Digital India” can connect maximum number of rural Indians to all over the world through Internet and how E-Commerce Industries can convert this mass of rural Indians for trading.
 
Brain Tumour Segmentation using Level Set Method and Affected Area Calculation
Get PDFMedical image processing is the most important and challenging field now days. MRI image processing is one of the parts of this field. Brain tumour segmentation in magnetic resonance imaging (MRI) has become an emergent research area in the field of medical imaging system. In this paper we proposed a variational level set method and some morphological operation to segment the brain tumour from MRI image by using MATLAB. Actually we describe variational formulation on geometric active contours that forces the level set function at zero level to be close to signed distance function and without re-initialization process. The variational formulation uses energy function and partial diferential equation to evolve the level set function. Tumour shape area is connected component in binary image and calculated this connected area using some properties of morphological operation
Electromagnetic Radiations: A Possible Impact on Population of House Sparrow (Passer Domesticus)
Get PDFThe modern world is a full of contamination of radiofrequency (RF), “electrosmog” in the urban centers especially after the rapid introduction of mobile telecommunications systems. The aim of this study is to determine the impact on population of house sparrow, Passer domesticus by electromagnetic radiation (microwaves) from phone antennae. By monthly monitoring in urban and rural area, it is found that the population of house sparrow is declining in the urban area, where cell phone towers are more as compared to the rural area in every season.
 
Modeling Transfer of Electrons between Energy States of an Electrolyte and CdS Thin Films using Gerischer Model
Get PDFA number of models have been developed to describe electron transfer between electrolytes and group II–VI binary semiconductors. In this report, a study was conducted to describe and model electron transfer between an inorganic semiconductor, (i.e. CdS) and a ferric oxidizing/reducing agent [i.e. K3Fe(CN)6/K4Fe(CN)6]. We describe the interfacial electron transfer using the semi-classical theory approaches as described by Marcus and later developed by Gerischer and therefore called Gerischer model as it is applied to heterogeneous electron transfer in a semiconductor - electrolyte interface. CdS thin films were grown by electro-deposition method on the indium tin oxide (ITO) substrates and were used as electrodes. The data collected was used to determine the kinetic constant rates and re-orientation energies as measured in the solutions with different concentration of redox system, Fe+3/ Fe+2. Experiments showed that when concentration of oxidized species increased and causing an increase in activity, the kinetic constant rates decreases inversely. Equally light induced current at 0.0V/Ag was higher when the ratio of the oxidant-reductant (i.e. 2/0.02 and 0.2/0.02) was high. EIS studies revealed that for the two ratios of. 2/0.02 and 0.2/0.02, the difference of current density was comparable to the transfer of the charge carriers for the oxidant-reductant electrolyte at 2/0.02 with respect to 0.2/0.02
Application of Bradford’s Law of Scattering to the Scientific Publications of Energy and Environment Research
Get PDFThis study has been made an attempt to describe the one of the most essential bibliographic laws i.e. Bradford law of scattering to test the scholarly publications of energy and environment in Australia. A total of 2802 papers published, out which 83.4% were journal articles and 99.7% were in the English language. According to Australian research, the output of Environmental Sciences Ecology (13.807%) account for the largest increase and it is occupied in the first place and Energy Fuels (6.208%) is in the 6th place during the present study. The three most productive journals with high citations were ‘Ecological Applications’ (= 4, 2721 citations), ‘Astrophysical Journal’ (= 44, 1614 citations), and ‘Monthly notes of the Royal Astronomical Society’ (= 38, 1389 citations) and the maximum number of citations contributed by ‘BAZZAZ FA’ from Harvard University, USA. In this study, based on the speculative aspects of Bradford’s Law of Scattering is tested and identified that the ratio depicts that it does not fit into the Bradford’s law of distribution
Effect of Hematocrit Level on the Blood Flow through Stenosed Artery: A Theoretical Study
Get PDFIn the paper we have focused the effect of Hematocrit on flow parameters, such as resistance, frictional resistance, and skin friction due to stenosis in the artery taking blood as non-Newtonian fluid. It has been found that resistance increases with the increasing of hematocrit level and stenosis height. It is also shown that a skin-friction increase with increasing of stenosis height and decreases with the decreasing of stenosis height. Moreover the effect of stenosis shape parameter is observed on resistance and skin-friction due to different hematocrit level. Finally we compare our result graphically
