Multiple components detection in motherboard using Mask R-CNN
Object detection is one of the main requirements during motherboard assembly process, especially when using SMT technology. Human fatigue is the major cause of error making while manual inspection. The grasp success rate will enhance if robot can get exact position of objects than relative to the end manipulator. With the advent of deep learning techniques the accuracy for object detection has increased drastically. A major challenge in many of the object detection systems is the dependency of other computer vision techniques for helping the deep learning based approach, which will lead to the slow and non-optimal performance. In this project a completely deep learning based approach to solve the problem of object detection in an end-to-end fashion. The method, called Mask R-CNN, extends Faster R-CNN by adding a branch for predicting an object mask in parallel with the existing branch for bounding box recognition. The model developed with a pre-trained model ResNet 101 and data collected from Computer Vision Lab. Mask R-CNN is easy to generalize to other tasks and also it shows better results with COCO dataset for instance segmentation, bounding box object detection and person key point detection.

Literature review on depth estimation using a single image
Depth estimation is an important component of understanding geometric relations within a scene. Different depth estimation techniques using a single image are analyzed in this survey paper. Depth estimation from a single image is often described as an ill-posed and inherently ambiguous problem. Recovering depth information in applications like 3D modeling, robotics, autonomous driving, etc. is more important when no other information such as stereo images, optical flow, or point clouds are unavailable. For the task of depth estimation using single images, learning based methods have shown very promising results.

An exploratory study to assess the stress and coping pattern among the employees of insurance company at Gwalior (M. P.)
An exploratory study to assess the stress and coping pattern among the employees of insurance company at Gwalior (M.P). To assess the levels of stress among the employees of insurance company. To assess the coping pattern among the employees of insurance company. To find out the relationship between the stress and coping pattern among the employees of insurance company. To find out the relationship of stress level with variables such as age Religion, education, type of family, marital status, head of family and economic status. To find out the relationship of coping pattern with variables such as age, religion, education, type of family, marital status, head of family and economic status. For the present study exploratory approach was considered appropriate. The purposive sampling method was adapted to collect the sample. Majority of employees have moderate stress (95%) and (5%) have mild stress. Majority of employees in insurance company have positive coping pattern (82%) and (18%) have negative coping pattern. Relationship between stress and coping pattern among employees of insurance company was having negative correlation (-.142) and statistically non-significant. The employees from selected insurance company have positive coping pattern as there age advances. The findings were also statistically significant at p level. The employees from joint family have positive coping pattern as compared to nuclear and extended family. These findings were also statistically significant at p level. The employees who are head of the family their coping pattern was negative as compare to others. These findings were also statistically significant at p level. Those employees who are (separated, divorced, spouse not living, spouse living) clubbed together as separated, had positive coping pattern as compared to married. These findings were also statistically significant at p level. The employees with adequate economic status their coping pattern was positive as compared to those who have inadequate economic status. These findings were also statistically significant at p level.

A single-phase integrated onboard battery charger using three-phase AC motor for plug-in electric vehicles with PFC
The growing market of plugin hybrid electric vehicle has certain limitations like more charging time, less driving range and fewer charging stations. PHEV chargers are classified as off-board and on-board chargers. Off-board chargers provide fast charging takes 20 mins to 1 hour while onboard chargers provide office daytime or home overnight charging takes 4 to 10 hours to fully charge a PEV battery. In this paper, a single-phase integrated onboard charger, using the PEV three phase ac machine and its traction converter, is proposed. The charging process enables Power Factor Correction (PFC) at the source end. Three phase winding of the AC machine is utilized as a mutually coupled inductor to produce a two-channel boost converter. A 3-kW prototype using a 220-Vrms, 3-phase PMSM is built to experimentally verify the performance of the proposed integrated charging approach. A nearly unity Power Factor (PF) and 3.96% Total Harmonic Distortion (THD) of input ac current is acquired with a maximum efficiency of 93.1%.

Formulation and evaluation of alfuzosin hydrochloride extended release tablets
Purpose The aim of the study was to design extended release tablets capable of producing a 20 h extended release profile there by eliminating the use of immediate release tablets which require a frequent administration of three tablets containing 2.5 mg of alfuzosin hydrochloride of daily dose. The present study deals with formulation of Alfuzosin Hydrochloride extended release tablets. Benign prostatic hyperplasia is a noncancerous prostate problem in which the normal elements of the prostate gland grow in size and number, requires an alpha-adrenergic blocker which is having optimum therapeutic window concentration for a prolonged duration. With the above characteristics Alfuzosin Hydrochloride was selected as active therapeutic agent. Methods. Alfuzosin HCl extended release matrix tablets were prepared by direct compression method by employing hydrophilic polymer HPMC K 100 M and Crosslinked xyloglucan (XG).The crosslinked XG was prepared by crosslinking of natural polysaccharide i.e XG with crosslinking agent Sodium trimetaphosphate (STMP). Simplex centroid design was applied for the optimization process. The prepared tablets were evaluated for various physicochemical parameters by official procedures. The in-vitro release study of matrix tablets was carried out in 0.01N HCl for 24 hours. Results. The tablets exhibited acceptable physicochemical characteristics and extended drug release pattern was observed for about 20h. Analysis of drug release data from the matrix system indicated that the drug release follows zero order kinetics by anomalous (non-fickian) diffusion. Conclusion. The crosslinked XG alongwith HPMC K 100M & DCP showed the potential for prolonged delivery of Alfuzosin over a 20 h period and therefore may be a suitable candidate for use in sustained release drug delivery system.

Availability of physical and infrastructure resources facilitating agricultural commodity trading in north Karnataka
Today in current scenario agriculture markets are the hub of the rural economy. Agricultural marketing today means more than linking the producer with the consumer, it includes the creation of a favorable economic environment for farmers to enthuse them to grow more and get proceeds from transactions. Many alternative forms, such as cooperative marketing, group marketing, contract marketing, futures trading, direct marketing, and e-commerce are in vogue. Agricultural produce markets are nerve centers from where marketing impulses are transmitted to put all the marketing activity on track and safeguard the interest of both farmers and consumers. Finally efforts should be made in terms of setting up proper marketing infrastructure that will facilitate the market participants to carry out the trading activities and also provide awareness, training, practical experiences, support needed to small, marginal and medium farmers at village/rural areas in terms of newer ways of agriculture marketing channels so that every farmer will be able to adopt better marketing techniques like common online platforms for selling their produce and get the remunerative prices for the same.
