We have analyzed high velocity resolution HI synthesis observations of the nearly face–on Sc galaxy NGC 1232. The neutral gas distribution extends well beyond the optical extent of the galaxy. As expected, local peaks in the HI column density are associated with the spiral arms. Further, the HI column density drops precipitously near the center of the galaxy. Closed contours in the velocity fie...

The paper focuses on new ways of organising product development projects in the construction industry. We discuss two such projects, one in Denmark and one in Finland where different forms of ‘network organisation’ have been tried out. The paper looks at how the existing structure in the construction industry affects the product development projects ‘organised-as-networks’. INTRODUCTION AND PUR...

the rapid and intensive progress in science and technology in the world, despite its abundant advantages and gifts of welfare and comfort for the mankind, in many ways, it has pushed human security to face grave tragic events. to give an example, the progress in chemistry before the great war, made it possible to produce and use toxic gases including phosgene gas causing enormous deaths of both...

A new type of spherical robot, called KisBot, is presented that includes arms and two types of driving mode: rolling and wheeling. In the rolling mode, the robot uses its arms as pendulums and works like a pendulum-driven robot, while in the wheeling mode, it extends its arms to the ground and works like a one-wheel car. The basic design idea of KisBot is introduced and a prototype is implement...

Automobiles are required to be even lighter for further achieving environmental protection through fuel economy improvement, as well as safety feature enhancement and drivability improvement. Automotive suspensions are also required to reduce their weight and thus more aluminum is being adopted. Aluminum forgings, in particular, are often applied because of their significant weight reduction ef...
