Change processes at the school building level are considered in order to formulate a number of locally based strategies, derived from research, for significantly improving schools and classrooms. Part I of the three-part analysis examines, through illustration, what is known about successful change processes at the school and classroom levels. Four particularly revealing studies are reviewed: (1) Huberman's case study of the ECRI reading program, (2) Stallings's program on improving the...

A study investigated at what point during eye fixations visual information is used in furthering the reading process. The study identified two aspects of information processing: registration, in which a light pattern on the retina triggers a pattern of neural activity in the visula cortex; and utilization, in which the registered pattern has an effect on the reading comprehension process. Specifically, the study sought to determine when this utilization of information occurs. Sixteen college...

Research involves the validation of the arm x-ray procedure for quantifying total body fat in samples of young and older men and women grouped by fitness category. Tests were completed on 200 subjects. Body fat was determined densitometrically, fatfolds and girths were taken of the right upper arm according to procedures outlined on the Phase 1 report ( ), and fitness was assessed by a treadmill test for maximal oxygen consumption (maxVO2). Subjects were placed into high and low fitness...

Pressed compacts were made of spray dried alumina containing water soluble polyvinyl alcohol or cellulose derivative binder. The burning out of organic binder on gradual heating was investigated by visual and microscopic observations of the cross section and by thermogravimetry. Burning out proceeds inward from the peripheries, gradually reducing the size of the black core, which first consists of a dark boundary layer and later turns uniformly black with a sharp boundary. A detailed mechanism...

A mathematical model is developed to determine the heat transfer rate of a cylindrical condenser section of a rotating heat pipe. This model is coupled to an existing code and an analysis is accomplished on both a smooth and axially finned condenser. The results of this analysis are compared to those of a similar analysis performed on a tapered condenser heat pipe using identical geometric and operating parameters. Results of the comparison indicate cylindrical condensers have a lower heat...

Further development of power transistor and power Darlington current carrying and voltage blocking capabilities led to the application of new General Electric devices in a 40 KVA Pulse Width Modulated DC Link VSCF system. The results indicate that the power Darlington devices selected exhibit large losses at the switching frequencies studied. Because of these losses, the devices (in their present status) are considered unacceptable for use in a DC VSCF system. (Author)

Computerized models are developed to predict the spreading, movement, evaporation, and dissolution of floating slicks formed by accidental spills of insoluble chemicals. Separate models are developed for continuous and instantaneous spills. The waterway can be a river, channel, lake, or coastal water. The models emphasize the dynamics of the thick slick (i.e., the gravity-viscous spreading phase) since the thick slick contains nearly all the spilled chemical and represents the most prolonged...

De Bruijn sequences have been the subject of recurring interest since their discovery over a century ago. Recent developments in radar ranging, error correcting codes, secure or limited access code generators, and mathematical modeling have made application of de Bruijn sequences because of their properties. The binary shift registers readily model digital computers with electronic states where 1 indicates the on state and 0 indicates the off state.

Networks were conceived in the 1950's, born in the 1960's and grew up in the 1970's. Today they constitute a technology with applications in a myriad of disciplines. Information sharing has been one of the areas greatly aided by computer networks. The Community On-Line Intelligence System (COINS) is an information sharing network in th-a U.S. intelligence community. CCINS offers batch and interactive services which are separate and independant of each other. The information acquisition process...

Values of three mean velocity components and six turbulence stresses measured in a turbulent shear layer upstream of a simulated wing-fuselage juncture and immediately downstream of the start of the juncture are presented nd discussed. Two single-sensor hot-wire probes were used in the measurements. The separated region just upstream of the wing contains an area of reversed flow near the fuselage surface where the turbulence level is high. Outside of this area the flow skews as it passes around...

Direct drag measurements were obtained on a flat plate with a spanwise row of vortex generators near the leading edge, to produce an array of stream wise vortices within the approaching turbulent boundary layer. The object was to explore the possibility of modifying the large scale structure of the boundary layer through embedded longitudinal vortices with a view to obtaining a reduction in wall shear. Both obstacle and vane type vortex generators were tested at free stream velocities 40 ft/sec...

An analysis and survey with conjecture supporting a preliminary data base design is presented. The data base is intended for use in a Computer Image Generator visual subsystem for a rotorcraft flight simulator that is used for rotorcraft systems development, not training. The approach taken was to attempt to identify the visual perception strategies used during terrain flight, survey environmental and image generation factors, and meld these into a preliminary data base design. This design is...

Wind-tunnel measurements were made of the wing-surface static-pressure distributions on a 0.237 scale model of a remotely piloted research vehicle equipped with a thick, high-aspect-ratio supercritical wing. Data are presented for two model configurations (with and without a ventral pod) at Mach numbers from 0.70 to 0.92 at angles of attack from -4 deg to 8 deg. Large variations of wing-surface local pressure distributions were developed; however, the characteristic supercritical-wing pressure...

The one-dimensional classical scalar string equation which involves linearization about a horizontal reference or equilibrium position is derived. We then derive a model for small motion about a nonhorizontal reference. The implications of our findings to modeling of flexible antenna surfaces such as that in the Maypole Hoop/Column antenna are discussed.

The development of missiles from early history to present time is put in perspective. The influence of World War II in accelerating the development of guided missiles, particularly through German scientists, is discussed.

The feasibility of reducing the atmospheric drag of low orbit solar powered satellites by operating the solar-cell array in a minimum-drag attitude, rather than in the conventional Sun pointing attitude was determined. The weights of the solar array, the energy storage batteries, and the fuel required to overcome the drag of the solar array for a range of design life times in orbit were considered. The drag of the array was estimated by free molecule flow theory, and the system weights were...
