Abstract: This study is concerned with riverbank erosion and population migration which has more impact on Bangladesh. The study is highly subject to riverbank erosion. Origin and Destination survey method are used for finding population migration and resettlement pattern and tracking population migration and resettlement. Riverbank erosion is causing socio-economic and environmental problems in Bangladesh. Different research had identified that people who suffered from riverbank erosion ended up as landless migrated people and this migration is a major contributory factor to recurrent poverty in Bangladesh. The study was found that two-third people migrate permanently one union to another union because they get support from their neighbors, relatives, friends and they also stay here due to low living cost comparatively another area. There are no specific policies to rehabilitate the erosion-hit people. Thus, it is time to formulate policies to address prevention of riverbank erosion as well as to rehabilitate the river-erosion migrants.

Abstract: The analysis of survey data becomes difficult in the presence of missing data. By the use of Least Squares and Stein Rule method, estimator for the parameters of interest can be obtained. In this study, proposed convoluted Weighted Least Squares and Stein Rule method is compared with some existing techniques where the data is considered missing completely at random (MCAR). The results show that other techniques are occasionally useful in estimating most of the parameter, but proposed (LSSR) technique perform better regardless of the percentage of the missing data under MCAR assumption.

Abstract: In this article we propose a method of using the extended Kalman filter combined with an inertial navigation system and a camera to assist in determining the location and calculate the parameters of a helicopter. These observations are combined with an inertial measurement instrument which uses the Kalman filter to collect accurately and promptly information about the location of a plane. The algorithms is simulated on Simulink and hardened by using dsPIC33F256 chip.

Abstract: Although Ethiopia is a young country with 46 per cent of the population under the age of 14, over five per cent of the 81 million Ethiopians are aged 60 years or more. This proportion of older persons is anticipated to nearly double to nine per cent by 2050. There are several factors that could hinder old people access to food such as income, health status, household size, disability and others (HAIE, 2011). This objective of this study was to assess the old people access to food and its determinants in Dire Dawa city. Total samples of 947 old people were taken by using cluster sampling over proportional allocation to each kebele. Quantitative and qualitative data has been collected from aged persons in Dawit Aid for Aged persons Association, Asegedech Association and other appropriate enumeration areas. The descriptive analysis resulted that 72.76% were members of the associations. Most (74.3%) members of the organization have medium and above food access. Additionally their life have been improved in terms of obtaining medical, clothing and counseling service after they joined the organizations. The ordinal logistic regression identified income source, occupation, owning a house and type of membership organization as determinants of daily food access for the elderly.

Abstract: With the increasing aging problem, house-for-pension program is attracting more and more people’s attention in China. As an important financial tool, reverse mortgage has been developed quite well in a number of developed countries across the globe. Therefore, with reference to the developed countries, it could be convenient and effective way to learn these mature and valuable experiences to develop old-age care products and systems which accord with the situation of China. The key of the practice of reverse mortgage relies on its pricing. The article therefore emphasizes on the pricing of reverse mortgage to research and expound. This paper tries to use a hybrid model to make a relatively comprehensive introduction of the product mix, pricing principle and the risk control of housing reverse mortgage. The potential issues that may confront during the course are discussed for future implementation.
