An Adaptive neural network for understanding website usage patterns
As the importance of the Internet rises, the need to create more adaptive and more usable web sites also grows. Most improvements to a website requires some knowledge of the site\u27s users and how they are interacting with the pages. However, web professionals today have relatively few good options for capturing this information. Certainly, there are software and services to help summarize the basic information from the web site logs. This could mean keeping track of the frequency of visits for the individual web pages that make up a site counting how many times the overall web site is visited from a specific web location, or other basic statistics
CAROTID ARTERY INTIMA-MEDIA THICKNESS AND 10-YEAR RISK OF HEART DISEASE IN DIABETIC PATIENTS: A COMPARATIVE STUDY
Objective: The aim of the present study was to assess the factors affecting carotid artery intima-media thickness (CIMT) and 10-year risk of heart disease in diabetic patients classified according to CIMT.
Methods: This was an analytical cross-sectional study conducted on 92 patients for 1 year. 10-year risk of heart disease was calculated using the American College of Cardiology/American Heart Association Guideline on the Assessment of Cardiovascular Risk. Based on CIMT, the subjects were classified into two groups. Group 1 contains subjects with CIMT <0.9 and Group 2 contains subjects with CIMT ≥0.9. The Mann–Whitney U-test, Pearson’s correlation, and descriptive statistics were used to compare and describe the data. The level of statistical significance was taken at p<0.05.
Results: Patients with 51–60 years of age group are high in number. Males were predominantly high than their counterparts. There is a statistically significant association between total cholesterol (p=0.001), high-density lipoproteins (p=0.000), low-density lipoproteins (p=0.001), postprandial blood sugar (p=0.000), and hemoglobin 1Ac (p=0.035) with CIMT. The mean 10-year risk of heart disease in Groups 1 and 2 is 13.13±15.40 and 23.63±17.57, respectively. There is statistically highly significant association (p=0.000) of 10-year risk of heart disease between two groups. There is a positive correlation (r=0.45, p<0.0001) between CIMT and risk of heart disease.
Conclusion: Our study found that greater the CIMT, greater the risk of the heart of disease
MCSA based mechanical fault analysis of three phase squirrel cage induction motor
This paper deals with mechanical fault analysis of
three phase induction motor using Motor Current Signature
Analysis. This is a reliable technique that can be used to monitor
the health of three phase induction motor. Three phase induction
motor is used to find the Current Signature before and after the
fault occurs. The FFT of Current signal is analyzed using
Advanced Signal processor to find harmonics present before and
after the fault occur. This data is used to detect the mechanical
faults way before they cause harm to the motor and power
system. Ball bearing fault is created practically to find the
harmonics components in the current drawn. Most of the
practical results match with the theoretical values obtained from
the literature
Beliefs and expertise in sequential decision making
This work explores a sequential decision making problem with agents having diverse expertise and mismatched beliefs. We consider an N-agent sequential binary hypothesis test in which each agent sequentially makes a decision
based not only on a private observation, but also on previous agents’ decisions. In addition, the agents have their own beliefs instead of the true prior, and have varying expertise in terms of the noise variance in the private signal. We focus on the risk of the last-acting agent, where precedent agents are selfish. Thus, we call this advisor(s)-advisee sequential decision making. We first derive the optimal decision rule by recursive belief update and conclude, counterintuitively, that beliefs deviating from the true prior could be optimal in this setting. The impact of diverse noise levels (which means diverse expertise levels) in the two-agent case is also considered and the analytical properties of the optimal belief curves are given. These curves, for certain cases, resemble probability weighting functions from cumulative prospect theory, and so we also discuss the choice of Prelec weighting functions as an approximation for the optimal beliefs, and
the possible psychophysical optimality of human beliefs. Next, we consider an advisor selection problem where in the advisee of a certain belief chooses an advisor from a set of candidates with varying beliefs. We characterize the decision region for choosing such an advisor and argue that an advisee with beliefs varying from the true prior often ends up selecting a suboptimal advisor, indicating the need for a social planner. We close with a discussion on the implications of the study toward designing artificial intelligence systems for augmenting human intelligence.https://arxiv.org/abs/1812.04419First author draf
A CRITICAL STUDY ON THE PROBLEMS OF ESL STUDENTS
Second-language instruction has come a long. Still, it has a long way to go. Collecting information from different approaches has been the method followed from the beginning. Probably this is the suitable approach as we propose many styles of learning and events to train the students in a better way. Further, a free approach allows teachers to glean the effective elements from many methods that really work in the classroom. Language learning methodologies worth when they succeed. Working with ESL issues is a bit difficult and tiring and also confusing at times. However, ESL students often show pleasure themselves to work on it. They know that they need to improve their English; usually they are quite well-prepared and show willingness to work. Language acquisition is a slow, painful process, but a bit of effort eventually adds up to fluency or at least a get through in a composition course. Things may move very slowly in the sessions with ESL students as they might work on it slowly till he/she gets a little bit command over it. The teacher needs to spend more time talking to the ESL students than he or she spends with the other students because the teacher needs to focus on the students with much interest and it needs a lot of attention. The paper benefits the teacher as well as the student as it gives a solution for the teachers to teach it in a better and an easy way. It makes easy for the students so that they can find a solution for their problems
Surat 2006 Floods: A Citizens’ Report
Surat is situated at the mouth of the river Tapi where it meets the Arabian Sea and has for centuries been a flood-affected area. The most recent floods however, were different because of the magnitude of their effect. Nearly 90 per cent of the households were affected; six of the seven wards of the city had water standing for days. It crippled the economy and affected people's coping abilities. In the wake of the floods the Department of Human Resource Development of the Veer Narmad South Gujarat University and the Centre for Social Studies conducted a study looking at how people coped with the disaster and the impact of the flood on their lives and the economy. It offers some pointers about how the impact can be mitigated in similar situations in the future

SIMULATION AND IMPLEMENTATION OF ELLIPTICAL MICRO STRIP ANTENNA AT 750MHZ
In telecommunication industry, several types of antennas are used. The most common of which are the micro strip patch antennas (also known as printed antennas) or patch antenna. Patch antennas can be used in many types of communications links that may have varied requirements. A single patch antenna provides a maximum directive gain of around 6-9 dBi. We can design it to work at multiple frequencies. It is available in various shapes and configuration, most common of which is a rectangular micro strip antenna (RMSA).In this project we are designing single fed annular ring micro strip ntenna. The software used to model and simulate the micro strip patch antenna is ZeelandInc’s IE3D software. IE3D is a full-wave electromagnetic simulator based on the method of moments. It analyzes 3D and multilayer structures of general shapes. It has been widely used in the design of MICs, RFICs, patch antennas, wire antennas, and other RF/wireless antennas. An evaluation version of the software will be used to obtain the results
Nutrient Utilization in Buffalo Bulls Fed Crop Residue Based Complete Rations Supplemented With or Without Yeast Culture
The present investigation was carried out to study the effect of feeding crop residue based complete rations supplemented with and without live yeast culture on nutrient utilization in buffalo bulls. In 4 x 4 LSD, four graded Murrah buffalo bulls (6 years; 330.7±30.63 kg) were randomly allotted to four dietary treatments viz., maize stover based complete ration (T1), T1 supplemented with yeast culture (T2), jowar stover based complete rations (T3) and T3 supplemented with yeast culture (T4). The complete rations were prepared by mixing maize or jowar stover and concentrate mixture in 60:40 proportions. The live yeast culture containing Saccharomyces cerevisiae at 6 x 1010 cfu/g was supplemented at the recommended level of 10 g/animal/day. Results revealed that the dry matter intake expressed as kg/d or as % of BW was similar among the four dietary treatments. The digestibility co-efficients of dry matter, organic matter, crude protein, ether extract, crude fibre, neutral detergent fiber, acid detergent fiber, hemi-cellulose, cellulose (P<0.01) and nitrogen-free extract (P<0.05) were higher in T2 when compared to others. All the buffalo bulls were in positive nitrogen, calcium and phosphorus balance. The digestible crude protein and total digestible nutrient content expressed as % in the diet consumed or kg/d was higher (P<0.01) in T2 as compared to other treatments. Thus, it is concluded that the performance of animals was better on maize stover based complete ration supplemented with live yeast culture (T2) as evidenced by higher plane of nutrition
