The Southwest Research Institute (SwRI) Peak Power Tracker (PPT) solution is the enabling technology for power constrained Small Satellite missions. The SwRI PPT solution combines 35 years of experience developing electronics for space flight on NASA Discovery, MIDEX, and SMEX missions with internal research and development. SwRI has delivered 8 flight model PPT modules for the NASA CYGNSS mission...
Muscle tissue bioreactors are devices which are employed to guide and monitor the development of engineered muscle tissue. These devices have a modern history that can be traced back more than a century, because the key elements of muscle tissue bioreactors have been studied for a very long time. These include barrier isolation and culture of cells, tissues and organs after isolation from a host organism;...
The illustrated case studies in Part III were prepared to help solidify the decision-making required for patients who are diagnosed with chondral disease of the knee. The cases are organized by level of complexity, taking into consideration substantial comorbidities such as tibiofemoral and patellofemoral malalignment, ligament disruption, and meniscal deficiency. The cases are presented in increasing...
A three million pixels photon counting area detector for the coherent diffraction imaging beam line (I13) of Diamond Light Source has been developed by a joint team of Diamond and STFC staff. The detector is the state of the art of X-ray detection technology since it exploits the latest generation of Medipix ASICs family that introduced a number of innovations. The specifications required by the beam...
In this paper, we analyze software that we inherited from another party. We analyze its architecture and use common design principles to identify critical changes in order to improve its flexibility with respect to a set of planned extensions. We describe flexibility issues that we encountered and how they were addressed by a redesign and re-implementation. The study shows that basic and well-established...
There is a large population of ageing distribution plant and equipment installed on electricity companies' networks and in many industrial and commercial locations. In order to achieve effective utilisation of these assets and make sound decisions on maintenance strategies, asset refurbishment or replacement, it is necessary to have reliable information on the condition of existing plant. The trend...
Phyllosilicate clays are assemblies of nano-plates of silicate with the dimension of height to length being 1 : 100 nm or more. The preferential face-to-face stacking of these silicate plates via van der Waals forces leads to formation of lamellar, layered structures. The exfoliated (delaminated) structures of these lamellar clays offer advantages as precursor for formation of nano-structured materials...
