A system and method for locating radiation sources

A radiation detection system is disclosed comprising of number of detector elements arranged in a regular pattern that allows for directional information to be collected based on the number of radiation interaction events in each detection element. This system is mounted to an unmanned vehicle. ... Oregon State University

Methods and systems for generating polycubes and all-hexahedral meshes of an object

A method for generating a polycube representation of an input object comprises: receiving an input volumetric representation of the input object; deforming the input volumetric representation to provide a deformed object representation; and extracting, by the processor, a polycube representation of the object from the deformed object representation. Deforming the input volumetric representation to provide the deformed object representation comprises effecting a tradeoff between competing objectives of: deforming the input volumetric representation in a manner which provides surfaces having normal vectors closely aligned with one of the six directions aligned with the set of global cartesian axes; and deforming the input volumetric representation in a manner which provides low-distortion deformations. ...

Routerless networks-on-chip

The disclosed technology concerns methods, apparatus, and systems for designing and generating networks-on-chip (“nocs”), as well as to hardware architectures for implementing such nocs. The disclosed nocs can be used, for instance, to interconnect cores of a chip multiprocessor (aka a “multi-core processor”). ... Oregon State University

Apparatus and method for electric hot water heater primary frequency control

. . An energy storing apparatus is provided which comprises: a first region having a thermostat which includes: a temperature sensor; a controller coupled to the temperature sensor; and a power-converter coupled to the controller; and a second region thermally coupled to the first region. An apparatus is provided which comprises: an interface to be coupled to an electric grid; a temperature sensor; a controller coupled to the temperature sensor; and a power-converter coupled to the controller, wherein the power-converter is to couple via passive devices to a heating element, wherein the power-converter is to apply power to the heating element according to a temperature sensed by the temperature sensor and a frequency of the electric grid.. ...
