This paper presents a stochastic model predictive control (SMPC) for stop maneuver of autonomous vehicles considering perception uncertainty of stopped vehicle. The vehicle longitudinal motion should achieve both driving comfortability and safety. The comfortable stop maneuver can be performed by mimicking acceleration profile of human driving pattern. In order to implement human-like stop motion, we propose a reference safe inter-distance and velocity model for the longitudinal control system. The SMPC is used to track the reference model which contains the position uncertainty of preceding vehicle as a chance constraint. We conduct simulation studies of deceleration scenarios against stopped vehicle in urban environment. The test results show that proposed SMPC can execute comfortable stop maneuver and guarantee safety simultaneously.

They favor healthy fashion items and think much of exercise, nutrition, and rest. They pursue the natural and comfortable style, whose ideas came from simple exercises such as health training and yoga and the easy and comfortable look observed at resorts. Their fashion style can be divided into three of fitness fashion, yoga fashion and resort fashion. First, the boxer fashion is characterized by the relaxing design and practicality. The major items of the fashion include running shirt-styled upper clothes, training pants, hooded shirts and sneakers. Simple and comfortable look should be induced from the combination of the items. Second, the yoga fashion was motivated by the comfortable yoga wear. It advocates stress-free spirit and comfortable and stable naturalism. Along with the advantages of the good feeling to wear and the functionality to help exercise better, the yoga fashion gives the wearer enough room to move around in, using the unique lines. Third, the resort wear refers to the kinds of clothes you tend to wear at the beach and the park. There are various kinds of the resort look; bathing suits, the beach wear you can wear with the bathing suit, the resort evening wear, the full-side look that you try on top of the bathing suit and is made of the same material of the bathing suit, and the marine look, the symbol of the summer. In short, the study attempted to investigate many trends occurring as the result of human recent increasing interest and concern in the quality of life, and the impacts of them on the fashion world. This kind of research that examines the background of the times and society will help to grasp with the fashion trends of the present and the future. And more studies should be conducted on the development of new and original design in clothes fashion, which reflects the characteristics identified in this kind of research.

Environment friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials we, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For examples, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural materials. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21century through recycled and reused materials.
