A high resolution programmable thermal test chip
… the need for more accurate and fine-grained thermal characterization methods. While numerical simulation remains a powerful tool for predicting on-chip temperature distributions, its accuracy ultimately depends on model assumptions and boundary conditions. To bridge this gap, A design and …

Geothermal systems in the Chalk of the south east of England: methods of predicting thermal transport in a fractured aquifer
… aquifer beneath London to supply "open loop" geothermal systems (Environment Agency, 2007). However, there has been little research conducted on how the water re-injected by these systems, which often differs in temperature by as much as 10°C, will interact with the fractured Chalk aquifer in …

Encapsulation of nanomagnetite within polycaprolactone microspheres for bone replacement
… behaviour when analysed using SQUID. In the thermal test, magnetite nanoparticles display smooth curves both in the heating and cooling processes and do not shows significant heat loss. Scanning electron microscopy and chemical analysis showed that the magnetite nanoparticles were evenly …

Ring motor front wheel for electric motorcycle applications
… simulation software such as Motor-CAD, and a thermal test for heat pipes is performed. A concept for packaging it is presented at the end. The machine is designed as a permanent magnet synchronous motor with an outer rotor. Minimizing weight while retaining performance was achieved by using …

Adaptive thermal modeling architecture for small satellite applications
… simply scaled to fit the mission. The varying thermal environment in space is particularly important to spacecraft design and operation because of its affect on hardware performance and survivability. The Adaptive Thermal Modeling Architecture (ATMA) discussed in this thesis is meant to bridge …

Long-Distance Flux Mapping Using Low-Cost Collimated Pyranometers
Concentrating solar thermal power tower plants with capacities of 100 MWe or greater require large heliostat fields with heliostats over 1,500 m (nearly a mile) away from the tower. The accuracy and performance of these heliostats must be evaluated and understood as new heliostat designs emerge to …

Data assimilation for verification of dry storage cask content
… indicator χ². Conventional statistical tests using the χ² value can be used to eliminate proposed cask loadings which are too-inconsistent with experimental measurements, but cannot be used to accept any particular cask loading and therefore lack the predictive capability to identify any …

Computational modeling and simulation of composite materials based on tomographic images
The goal of this work is to enable automated thermal and mechanical finite element analysis of heterogeneous composite materials based on tomographic images of material specimens. Of particular interest are microvascular materials containing embedded micro-channnels through which a coolant or …

Refurbished and 3D Modeled Thermal Vacuum Chamber
<p>Spacecraft testing includes acoustics, vibrations, and thermal vacuum. Cal Poly’s Space Environments Lab is equipped with multiple vacuum chambers, but no thermal vacuum chamber. The purpose of this thesis is to incorporate an ATS Chiller system with the HVEC vacuum chamber so students are able …

Somatosensory processing by rat medial pontomedullary reticular formation neurones : responses to innocuous and noxious thermal and mechanical stimuli
… particular emphasis on the response to cutaneous thermal stimuli. Thermal test stimuli were employed as these were deemed to be more precisely quantifiable than other forms of cutaneous stimulation. Activity was recorded from 235 PMRF neurones in 94 female Long Evans rats (270 to 320 g) …
