A Follow-Up Study of the Business Students Who Graduated from Intermountain School From 1966-68

Brigham City, Utah, is the location of the largest boarding school sponsored by the United States Bureau of Indian Affairs. This institution, Intermountain School, is for the disadvantaged Navajo student who has resided on the Navajo reservation, which is located in the states of Utah, Arizona, and New Mexico. Intermountain School is divided into different departments, such as guidance, elementary, high school, and vocational. Within the Vocational Department are several training programs. One of these programs is the Business Department. Students who select business as their vocational training program enroll during their junior year for three hours each day and during their senior year for the same number of hours per day. During the junior year, the business students take two semesters of typewriting, two semesters of general business, nine-weeks of office machines, nine weeks of filing, and one semester of selling. Senior year students take two semesters of accounting, one semester of retailing, two semesters of typewriting, and one semester of data processing and office practice

The Role Of Perennial Grasses In Sustaining Production In Semi-Arid Areas

A GP article on the role of perennial grasses in sustaining production in semi-arid areas.In much of Africa, including large parts of Zimbabwe, the rainfall is too low and erratic to sustain successful agricultural cropping so that economic production depends upon using herbivores (e.g. cattle) to convert natural vegetation into products which are of value to man (e.g. meat, milk, hides). In Africa, significant and increasing human deprivation is occurring In these semi-arid savanna range-lands. Solutions to these problems are complicated as they involve interactions between socio-political, economic, financial and ecological factors, often operating under very different time scales

Aerodynamic configuration development of the highly maneuverable aircraft technology remotely piloted research vehicle

The aerodynamic development of the highly maneuverable aircraft technology remotely piloted research vehicle (HiMAT/RPRV) from the conceptual design to the final configuration is presented. The design integrates several advanced concepts to achieve a high degree of transonic maneuverability, and was keyed to sustained maneuverability goals while other fighter typical performance characteristics were maintained. When tests of the baseline configuration indicated deficiencies in the technology integration and design techniques, the vehicle was reconfigured to satisfy the subcritical and supersonic requirements. Drag-due-to-lift levels only 5 percent higher than the optimum were obtained for the wind tunnel model at a lift coefficient of 1 for Mach numbers of up to 0.8. The transonic drag rise was progressively lowered with the application of nonlinear potential flow analyses coupled with experimental data

Bifurcation in Rotational Spectra of Nonlinear AB2_2 Molecules

A classical microscopic theory of rovibrational motion at high angular momenta in symmetrical non-linear molecules AB$_2$ is derived within the framework of small oscillations near the stationary states of a rotating molecule. The full-dimensional analysis including stretching vibrations has confirmed the existence of the bifurcation predicted previously by means of the rigid-bender model. The formation of fourfold energy clusters has already been experimentally verified for H$_2$Se and it has been demonstrated in fully-dimensional quantum mechanical calculations using the MORBID computer program. We show in the present work that apart from the level clustering, the bifurcation produces physically important effects including molecular symmetry-breaking and a transition from the normal mode to the local mode limit for the stretching vibrations due to rovibrational interaction. The application of the present theory with realistic molecular potentials to the H$_2$Te, H$_2$Se and H$_2$S hydrides results in predictions of the bifurcation points very close to those calculated previously. However for the lighter H$_2$O molecule we find that the bifurcation occurs at higher values of the total angular momentum than obtained in previous estimations. The present work shows it to be very unlikely that the bifurcation in H$_2$O will lead to clustering of energy levels. This result is in agreement with recent variational calculations.Comment: latex, 19 pages including 2 figures provided as *.uu fil

Implementing Racing AI using Q-Learning and Steering Behaviours

Artificial intelligence has become a fundamental component of modern computer games as developers are producing ever more realistic experiences. This is particularly true of the racing game genre in which AI plays a fundamental role. Reinforcement learning (RL) techniques, notably Q-Learning (QL), have been growing as feasible methods for implementing AI in racing games in recent years. The focus of this research is on implementing QL to create a policy which the AI agents to utilise in a racing game using the Unity 3D game engine. QL is used (offline) to teach the agent appropriate throttle values around each part of the circuit whilst the steering is handled using a predefined racing line. Two variations of the QL algorithm were implemented to examine their effectiveness. The agents also make use of Steering Behaviours (including obstacle avoidance) to ensure that they can adapt their movements in real-time against other agents and players. Initial experiments showed that both types performed well and produced competitive lap times when compared to a player
