Formation of double ring patterns on Co2MnSi Heusler alloy thin film by anodic oxidation under scanning probe microscope
Double ring formation on Co2MnSi (CMS) films is observed at electrical
breakdown voltage during local anodic oxidation (LAO) using atomic force
microscope (AFM). Corona effect and segregation of cobalt in the vicinity of
the rings is studied using magnetic force microscopy and energy dispersive
spectroscopy. Double ring forma-tion is attributed to the interaction of
ablated material with the induced magnetic field during LAO. Steepness of
forward bias transport characteristics from the unperturbed region of the CMS
film suggest a non equilibrium spin contribution. Such mesoscopic textures in
magnetic films by AFM tip can be potentially used for memory storage
applications.Comment: 7 pages, 5 figure
MRI image segmantation based on edge detection
Cílem této práce je představit základní segmentační techniky používáné v oblasti medicínského zpracování obrazových dat a pomocí 3D prohlížeče schopného zobrazit 3D obrazy implementovat segmentační modul založený na hranové detekci a vyhodnotit výsledky. Navrhovaný prohlížeč je sestavený v prostředi Matlab GUI a je schopen načíst objem 3D snímků představující lidskou hlavu. Navrhovaný segmentační modul je založen na použití hranových detektorů, zejména Cannyho detektoru.The aim of this thesis is to present the basic segmentation techniques uses in the field of medical image processing and by using a 3D viewer able to visualize 3D images, implement a segmentation module based on edges detection and evaluate the results. The proposed viewer is a 3D viewer build using matlab GUI and is able to load a volume of images representing the human head. The proposed segmentation module is based on the use of edge detectors particularly the Canny algorithm.

The mirror, as a self-awareness enhancing tool, which can modify food consumption behaviours
Many health problems are linked to obesity and being overweight, however there is little evidence that the diet industry is actively helping people to lose weight. Additionally, some weight-loss plans have even caused medical harm such as fatigue, hair loss, dizziness, and other negative symptoms (National Institute of Health, 1992). Moreover, there is a clear relationship between the physical environment and food consumption. As research by Melin and Gotestam (1981) stated minor changes in the physical environment can promote therapeutic changes in eating behaviour. Therefore, environmental manipulation and altering design elements may affect food consumption. In addition, weight loss programs are difficult to apply due to time constraints, motivational issues or cost. In this study the researchers aimed to investigate the design of the physical environment by including a mirror and considering its relationship to food consumption. The sample consisted of 30 females from Jeddah City, Saudi Arabia. The Paired T-test was employed to assess consumption time before and after the implementation of the mirrors. Firstly, the researchers measured the food before and after consumption. Secondly, they measured time spent consuming food. In addition there was an observation of eating behaviours. The results found the presence of the mirror made the participants eat less and spent more time adjusting and modifying their behavior such as eating quickly and chewing food. Self-awareness seems to be crucial in instigating a change of eating behaviour. The practical applications of this study are potentially wide reaching and should demonstrate the benefit of using mirrors to encourage a healthier society and help people changing the bad eating habits and lose weight. There is a high statistical difference (P=0.001) between eating time in front of the mirror and without the mirror. Keywords: Mirror, Food consumption, self-awareness, interior design, behavior
Redesigning the Indian food security system through e-governance: the case of Kerala
The link between e-governance and development has been widely leveraged for policy formulation in India, however, little is known about its application to food security. This paper fills the gap with a study of Kerala, where the Public Distribution System (PDS), the main national food security program, has been digitalized in its main functions. Findings reveal that the digital program has been purposefully devised to combat the problem of diversion ("rice mafia") of PDS goods to the market: however, issues of partial coverage and mistargeting remain. Lessons are drawn for other states computerizing the PDS and their social safety nets
