This paper has presented a review on different image segmentation techniques. The image segmentation; segments a given image into separate regions and objects. It is widely used in various vision applications like face detections, motion detection etc. The overall objective of this paper is to review various techniques of image segmentation. The short comings of image segmentation techniques will also be evaluated. This paper ends up with the analytical solution to overcome the problems of the existing techniques.

The problem of capacitor allocation in electric distribution systems involves maximizing energy and peak power loss reductions by means of capacitors installation. This paper presents a novel approach using reinforcement learning (RL) algorithm to determine suitable candidates' nodes in a distribution system for capacitor placement. The problem formulation considers two distinct objectives related to total cost of power loss and total cost of capacitors including the purchase and installation costs. The proposed method of this article uses RL for sizing and placing of capacitors in radial distribution feeders. The proposed method has been implemented in a software package and its effectiveness has been verified through a 9-bus radial distribution feeder, 34-bus radial distribution feeder along with 33-bus and 66-bus distribution systems. A comparison has been done among the proposed method of this paper and similar methods in other research works that shows the effectiveness of the proposed method of this paper for solving optimum capacitor planning problem.

Workplace deviant behaviors have caused organizations to suffer losses. As such this study explored the relationships between employees’ personality trait of emotional intelligence and workplace intelligences. One hundred and sixty-two participants completed the Self-Administered Schutte Self-Report Emotional Intelligence Test (SSREIT) and workplace deviance test. The findings showed a negative but significant relationship between emotional intelligence and workplace deviant behaviors. Also discussed were the level of respondents’ emotional intelligence and workplace deviance according to demographic factors. Possible implications for intervention and treatment efforts are discussed.

This paper tries to view monetary policy and national economy. Economic growth is simple defined as a positive quantitative increase in the country output of goods and services (Onwukwe 2003). Produced in a country within a specified period of time. Monetary policy is of importance to every developing nation. Every economy strives to achieve sustainable economic growth and development-explained in terms of positive sustainable increase in Gross Domestic Product (GDP) using the OLS Regression Analysis It was observed that the money supply (m2) contributed positively to the growth of the economy while nominal exchange rate and inflation have a negative impact on GDP which implies that inflation is a constrain to Exchange rate being negative implies that high rate of depression of naira is affecting production capacity especially as most production inputs are being imported and as such the paper recommends amongst others that a Persistent rise in general price level of goods and services must be controlled by the government in order to fight against inflation. This will boost the growth of the economy.

Texture segmentation is the process of partitioning an image into regions with different textures containing similar group of pixels. Texture is an important spatial feature, useful for identifying object or region of interest. In texture analysis the foremost task is to extract texture features, which efficiently embody the information about the textural characteristics of the image. This can be used for the segmentation of different textured images. This paper presents a new approach for color texture segmentation using Haralick’s features extracted from color co-occurrence matrices. The originality of this approach is to select the most discriminating color texture features extracted from the color co-occurrence. Symbolic Object Approach is used for achieving texture segmentation.

Kalamkari work is an art form of textile tradition, using modrants and natural dyes. Kalamkari started off during the Mughal dynasty and presently Andhra Pradesh is the largest producer of Kalamkari fabric. With the emergence of high quality machine looms and acceptance for printed textiles, Kalamkari art came on the verge of extinction. However, printed Kalamkari is a new craze among the current generation as it is a combination of traditional and modern trends. Present study is to analyse the perception of customers towards kalamkari products with respect to four marketing mix elements. Statements related to product, price, promotion and place were offered to customer and their responses, further analysed to summarise and draw inferences.

There is a growing demand for the need of alternative fuels for transportation. Increasing the efficiency and reducing the exhaust gases in engines have been dominant in the fields of research. The exhaust gases contain numerous pollutants that are extremely harmful though in chronic conditions. Hence, Electromagnetic engines were created that uses the combined power of an electromagnet as well as a permanent magnet. While these engines have already proven their worth as alternative sourced engines, non-polluting and eco-friendly, the current challenge is to make them more efficient, reliable and cost effective.

Web Services describes an identical way of integrating Web-based applications. For satisfying users demands these services have higher probability. All these services are publicly offered as a web data in the web repository. Web Services are of two kinds likely SOAP and REST offer different methods to invoke a service. Mobile and cloud applications, social networking websites, and automated business processes are among the drivers fueling the need for RESTful Web APIs. A survey on approach that is to be applied for analyzing and selecting web services from the number available web service is be conducted.

Hyperlipidemia is commonly ascribed to obesity. In the current study, the association of anthropometric profile with hyperlipidemia after adjustment for important confounding variables such as smoking, alcohol intake, and diabetes in volunteers with elevated lipoproteins was analyzed. Anthropometric assessment included measurement of weight, height, waist and hip circumferences. Serum levels of total cholesterol (TC), High- density lipoprotein-cholesterol (HDL-C) and triglyceride (TG) were measured. Low-density lipoprotein-cholesterol (LDL-C) was calculated by the Friedewald formula. Statistical analysis was done to examine the associations between anthropometric variables and lipids. The mean age of the study population was 63.31±9.56 years (30-80 yrs). Majority of individuals (51.5%) were in the age group of 61-70 years. Nearly 75.7% and 64.7% of the male and female population of the study respectively had BMI >30 kg/m2. Overall analysis of data revealed that HDL-C and BMI were correlated negatively (r= -0.25, p<0.05), whereas other lipid sub fractions did not have any significant association with the markers of obesity.

Abdominal pregnancy is a very rare obstetric complication which is extremely dangerious to the mother as well as the fetus. The diagnose can be difficult using ultrasounds beyond the first trimester,even then a high index of suspicion remains necessary. In this report, we present a primigravida woman accounted for pelvic pain and late periods into the Emergency room.
