Visibility-Aware Navigation Among Movable Obstacles
… of visibility-aware robot navigation among movable obstacles (VANAMO). A variant of the well-known NAMO robotic planning problem, VANAMO puts additional visibility constraints on robot motion and object movability. This new problem formulation lifts the restrictive assumption that the map is …

Conceptual design of a building with movable parts
… height and follows the shape of a "T", it has a movable structure on its top that can rotate 360 degrees. Because of the changing geometry of the building due to the rotation of the upper part, two assumptions can be made in the structural analysis: a. that the changing geometry drastically …

Brill-Noether-type theorems with a movable ramification point
The classical Brill-Noether theorems count the dimension of the family of maps from a general curve of genus g to non-degenerate curves of degree d in projective space Pr. These theorems can be extended to include ramification conditions at fixed general points. This thesis deals with the problem …

3-D Numerical Simulation Of Dam-Break Flows Over Movable Beds
Irvin Cooper was a prominent music educator in boys’ adolescent voice change research. Dr. Cooper developed the Cambiata concept as a method for teaching boys to sing throughout the voice change. This method was starkly different from the traditional model that encouraged the changing voice to be …

Laterally Movable Gate Field Effect Transistor (LMGFET) for microsensor and microactuator applications
Laterally Movable Gate Field Effect Transistor (LMGFET) invented at LSU as a microactuator is the subject of study in this research. The gate moving in lateral direction in a LMGFET changes channel width but keeps the channel length and the gap between the metal gate and the gate oxide constant. …

Supramolecular NanoStamping (SuNS) : fabricating nano/bio devices using DNA as a movable type
When a useful device is developed, it always requires a mass-production technique to industrialize it. In the era of nano/biotechnology, the development of printing techniques has not followed the speed of the inventions of novel devices. One of the main challenges is handling at the same time the …

A continental shelf bottom boundary layer model : the effects of waves, currents, and a movable bed
A simple model for the bottom boundary layer on the continental shelf is presented. The governing equations are developed for a stratified, turbulent Ekman layer in a combined wave and current flow over a moveable sediment bed. An eddy diffusivity closure scheme that includes the effect of …

Infants' Reasoning About Objects in the Physical World
… 9-month-olds use to distinguish between movable and immovable objects. The results from these experiments revealed that 9-month-olds attended to both verticality and object width. Furthermore, with the addition of width, verticality was elaborated to take width into account. Thus, for …

Two-dimensional Mapping of Interface Thermal Resistance by Transient Thermal Impedance Measurement
… value in TABLE 2 3. The working principle of the movable thermal sensor – Zth measurement and its structure function analysis – was then evaluated by sequence. The Zth measurement was evaluated by measuring the Zth change of devices induced by degradation in sintered silver die-attach layer during …
