Advanced Energy-Resolving Imaging Detectors for Applications at Pulsed Neutron Sources

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Department of Energy
Topic: 09A-2013
Budget: 01/01/13 - 12/31/13
PI: Mr. W. Bruce Feller

A number of unique non-destructive testing techniques and fundamental research studies are enabled by the modern bright pulsed neutron sources. In addition to all the methods previously developed at continuous neutron sources the pulsed structure of neutron beam enables a number of novel methods with the measurement of neutron energy th...

New Mobile Game-based Application for Reliable Neurocognitive Assessment

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Army
Topic: A12A-T029
Budget: 08/31/12 - 03/30/13
PI: Alexandra Geyer

Superior cognitive function is necessary for Warfighters to be able to critically assess their surrounding environment, quickly and effectively solve problems, make decisions, and adapt to changing situations. Reliable assessment of cognitive status changes is not only important for Soldier performance, but could be critical for diagnosing vario...

Bonded Joint Analysis Method

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Navy
Topic: N12A-T004
Budget: 08/15/12 - 03/15/13
PI: Dr. Akhilesh Jha

Adhesive bonds are increasingly finding their applications in aerospace and automotive structures. The adhesive bonding gets rid of fasteners, thus reducing stress concentrations and damage initiation sites. In addition, elimination of fasteners results in significant weight savings. In order to use adhesive bonding with confidence and certify i...

High frequency (HF) direction-finding (DF) system based on an array of high-Tc superconducting quantum interference devices (SQUIDs)

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Air Force
Topic: AF10-BT40
Budget: 11/15/11 - 08/15/12
PI: Dr. Stuart Berkowitz

ABSTRACT: In Phase I, we will analyze and design a physically small superconducting antenna for HF DF. We will develop a set of target antenna specifications. We will model and simulate a superconducting antenna for this application, including control electronics. We will complete an array design and device fabrication. We will measure noise pro...

High frequency direction-finding system based on high-Tc Ion-Damaged Josephson Junction SQUID arrays

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Air Force
Topic: AF10-BT40
Budget: 07/15/11 - 04/14/12
PI: Georgy Prokopenko

ABSTRACT: The overall goal of this project is to develop a small size, weight and power Direction Finding (DF) system based on SQUID array technology. High sensitivity, linearity, wide bandwidth of SQUID arrays antenna sensors will be enable close spacing of smaller antennas even for HF range. The SQUID arrays will be fabricated using high-tem...

Probabilistic and Relational Inferences in Dynamic Environments (PRIDE)

Phase 2 STTR

Institution: University of California, Berkeley

Agency: Defense Advanced Research Projects Agency
Topic: ST081-004
Budget: 01/18/11 - 04/15/13
PI: Avi Pfeffer

Uncertainty on the modern battlefield makes mission planning and decision making extremely complex for field commanders. Mission planners can be aided by initial and ongoing situation assessment, future state estimation, assessment of the current plan s probability of success, what-if analysis, and suggestions for decisions. At present, few auto...

Probabilistic Prediction of Location-Specific Microstructure in Turbine Disks

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Navy
Topic: N10A-T028
Budget: 06/28/10 - 04/30/11
PI: Dr. Shmuel L Weissman

Turbine efficiency improves with increased operating temperature. Consequently, the rim zone of disks operates at high temperatures where creep is the main concern. The bore and web zones operate at lower temperatures, where strength is the driving design criterion. Procedures to produce disks that can meet both demands include dual heat-treatme...

Buoyant Active Sensor System (BASS) for Riverine Mapping

Phase 1 STTR

Institution: University of California, Berkeley

Agency: Navy
Topic: N10A-T024
Budget: 06/28/10 - 04/30/11
PI: Eric Wemhoff

There is need for fast, easy-to-operate, and low-risk methods for mapping geography, velocity, and bathymetry of rivers. River charts can be nonexistent or inadequate because of changes in water volume, tides, sediment transport, flooding, and other events. This is a hindrance and a hazard for navigation and other operations. Currently, procedur...

Robust Model for Behavior of Complex Materials during Spin Testing

Phase 2 STTR

Institution: University of California, Berkeley

Agency: Air Force
Topic: AF08-T013
Budget: 03/31/10 - 03/31/12
PI: Dr. Shmuel L Weissman

The objective of this project is to develop a practical finite element-based simulation of spin-pit tests of disks. The performance of disks in spin-pit tests critically depends on localized effects, such as residual stresses, dislocations, and microstructure gradients. Therefore, a two-scale modeling approach is adopted. At the global-scale, th...
