Evolutionarily, man is a terrestrial mammal, adapted to land. Aviation and now space/microgravity environment, hence, pose new challenges to our physiology. Exposure to these changes affects the human body in acute and chronic settings. Since skin reflects our mental and physical well-being, any change/side effects of this environment shall be detected on the skin. Aerospace industry offers a u...

Aerospace industry is a value-added and technology integrated industry. Sheet metal parts are important portion of aerostructures. The sheet metal production line combines five different routing types together. This study tries to make a comparison between job shop layout and cellular layout with lean concept. According to precedence diagram of sheet metal fabrication process, the model and mea...

Aerospace medicine is the medical discipline responsible for assessing and conserving the health, safety, and performance of individuals involved in air and space travel. With the upward trend in airline travel, flight-related oral conditions requiring treatment have become a source of concern for aircrew members. Awareness and treatment of any potential physiological problems for these aircrew...

Lean techniques are having a major impact on aerospace manufacturing. However, the cost and value of aerospace (and many other) products is determined primarily in product development. Migrating lean to engineering processes is ongoing in the industry, and a subject of study at the MIT Lean Aerospace Initiative. This paper summarizes findings to date, with references to both research literature...

Six years after Congress began reducing defense outlays, small California machine shops and aircraft parts suppliers remain highly dependent on the aerospace industry. Many firms in these two segments of the state's small defense aerospace supplier base have not branched into production of cutting-edge products for commercial customers. And other firms in these segments also may face shortages ...
