Austin Model 1
Austin Model 1, or AM1, is a semi-empirical method for the quantum calculation of molecular electronic structure in computational chemistry. It is based on the Neglect of Differential Diatomic Overlap integral approximation. Specifically, it is a generalization of the modified neglect of differential diatomic overlap approximation. Related methods are PM3 and the older MINDO. AM1 was developed by Michael Dewar and co-workers and published in 1985. AM1 is an attempt to improve the MNDO model by reducing the repulsion of atoms at close separation distances. The atomic core-atomic core terms in the MNDO equations were modified through the addition of off-center attractive and repulsive Gaussian functions. The complexity of the parameterization problem increased in AM1 as the number of parameters per atom increased from 7 in MNDO to 13-16 per atom in AM1. The results of AM1 calculations are sometimes used as the starting points for parameterizations of forcefields in molec ...

Boeing Model 1
The Boeing Model 1, also known as the B & W Seaplane, was a United States single-engine biplane seaplane aircraft. It was the first Boeing product and carried the initials of its designers, William Boeing and Lt. Conrad Westervelt USN. Design The first B & W was completed in June 1916 at Boeing's boathouse hangar on Lake Union in Seattle, Washington. It was made of wood, with wire bracing, and was linen-covered. It was similar to the Martin trainer aircraft that Boeing owned, but the B & W had better pontoons and a more powerful engine. The first B & W was named ''Bluebill'', and the second was named ''Mallard''. They first flew on June 15, 1916, and in November, respectively. Operational history The two B & Ws were offered to the United States Navy The United States Navy (USN) is the naval warfare, maritime military branch, service branch of the United States Department of Defense. It is the world's most powerful navy with the largest Displacement (ship), displac ...

Breese-Dallas Model 1
The Breese-Dallas Model 1 or Breese model X was a prototype single engine airliner that rapidly changed hands throughout the 1930s. It was also known as the Michigan Aircraft Company Model 1, and the Lambert Model 1344. Design and development Vance Breese partnered with Detroit auto salesman, Charles Dallas to produce a modern, transcontinental, all-metal construction cargo aircraft. The aircraft was engineered by Art Mankey with some part-time design work by Jerry Vultee, who would go on to develop a slightly larger concept called the Vultee V-1. The aircraft is a six-passenger, all-metal, single-engine, low-wing monoplane with hydraulically retractable conventional landing gear. The center fuselage is welded steel tubing. The cockpit used a split forward slanting windshield popular on large aircraft of the period, with rearward sliding canopy panels over the pilots. There is a large passenger doorway just behind the right wing. The aircraft was constructed around an eight-inch ...

Fleet Model 1
The Fleet Model 1 (originally the Consolidated Model 14 Husky Junior) and its derivatives are a family of two-seat trainer and sports biplanes produced in the United States and Canada in the 1920s and 1930s. They all shared the same basic design and varied mainly in their powerplants. Development The Fleet Model 1 and its derivatives were all orthodox biplanes with staggered, single-bay wings of equal span and fixed tailskid undercarriage. Accommodation was provided for two in tandem, originally sharing a single open cockpit, but in most examples in separate open cockpits. The fuselage was made of welded steel tube with triangular-layout Warren truss construction pattern side structures typical of the time, and the wings had a wooden spar with duralumin ribs, the entire aircraft being fabric-covered. Despite a superficial resemblance to Consolidated's highly successful Trusty and Husky designs (hence the "Husky Junior" nickname), the Model 14 was an all-new design. Original ...

JSP Model 1 Architecture
In the design of Java (programming language), Java Web applications, there are two commonly used design models, referred to as Model 1 and JSP model 2 architecture, Model 2. In Model 1, a request is made to a JavaServer Pages, JSP or servlet and then that JSP or servlet handles all responsibilities for the request, including processing the request, validating data, handling the business logic, and generating a response. The Model 1 architecture is commonly used in smaller, simple task applications due to its ease of development. Although conceptually simple, this architecture is not conducive to large-scale application development because, inevitably, a great deal of functionality is duplicated in each JSP. Also, the Model 1 architecture unnecessarily ties together the business logic and presentation logic of the application. Combining business logic with presentation logic makes it hard to introduce a new 'view' or access point in an application. For example, in addition to an ...
