The compass uses a set of three magnetic sensors, which give a stable and accurate three-axis measurement of the Earth's magnetic field vector H. This measurement has been used to solve algebraically for the magnetic heading given roll and pitch attitude measurements from some external source such as a mechanical artificial horizon (AH) gyroscope. A major research aim has been to make the compass independent of external roll and pitch measurements. It has been found that, given the pitch, the roll and heading angles can be estimated in actual flight via an innovative algorithm which minimizes the quadratic norm error between H (measured) and H/spl circ/ computed using the estimated roll and heading.","PeriodicalId":199600,"journal":{"name":"Southcon/96 Conference Record","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130643862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Managers and executives have been surprised to learn that failing to move steadily forward in the 1990s is equivalent to falling behind. The concept of the continuous improvement cycle has undergone several transformations as various catch names have come in and out of vogue. Total quality management (TQM) has endured largely because of its broad acceptance at the time of the program's inception and the wide availability of supporting documentation and implementation guidelines. This paper details some of the TQM program's successes and failures in a defense industry, electronics and processing plant over an 18 month period and guidance for anyone wishing to implement such a program.","PeriodicalId":199600,"journal":{"name":"Southcon/96 Conference Record","volume":"79 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124506362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That means you have to speed up your development process. In order to deliver the best products, your process must allow for a well thought out and implemented feature set that will appeal to the market segment you are targeting. Here, the author describes how a well-defined product development process is crucial to reducing the amount of time it takes to introduce a new product to the marketplace. You need to look at all the aspects of introducing a new product right from the start. Your chances of being successful in the marketplace depend on a well thought out product and all aspects associated with it. He argues that it is important to take a holistic approach to the development of any new product. This will make your products easier to design, market, sell, maintain, and support and will increase your overall chances of initial success. In the long run, this same development process will ensure that you can bring second and third generation products to the market before your competitors can begin to achieve the same acceptance level as your first generation products.","PeriodicalId":199600,"journal":{"name":"Southcon/96 Conference Record","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127998347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
