The research project provides for the advancement of knowledge of and methodology for fretting phenomena modeling specific to nuclear fuel rod systems to preclude component failures. Grid-to-rod-fretting (GTRF) remains the most common cause of fuel rod failures and associated performance issues in pressurized water reactors (PWR). GTRF denotes the deterioration of the surface integrity of nuclear fuel rods and supporting spacer grid systems attributed to the cumulative effects of surface contact dynamics.
The objective of the proposed research is to investigate novel solid-state materials that have potential for hydrogen storage applications in fuel cell electric vehicles. Of interest are materials that can store hydrogen at ambient conditions and low pressures, have high gravimetric and volumetric hydrogen capacities, and can be safely packed into a hydrogen storage tank for automotive use. The research will focus on assessing the feasibility of threedimensional structures consisting of two-dimensional layered nanomaterials such as graphene as viable media to store hydrogen.
Fine particulate air pollution is recognized as causing health problems globally, but health researchers are just starting to understand where people receive their exposure, which will influence policies and regulations. There is a need for size-resolved particle measurements using a device that can be carried easily by a person. Nanozen has built such a device, and it could be used also for workplace ventilation control. However, first the sensor response to a wide range of particle sizes and compositions must characterized.
Cold Spray is a coating additive manufacturing process relying on the particle kinetic, with particles plastically deforming upon impact with the substrate and adhering to it. While the production of thin aluminum/aluminum alloys coatings (below 1mm) by Cold Spray is fairly common, the production of thick coatings (> 1mm) and large net-shape parts has been more challenging. Equispheres patent-pending atomization technology produces free-flowing, uniform spherical metal powders, with narrow particle size distribution, excellent sphericity and flowability.
There have been many new operational drivers that require changes to the traditional training processes in small and medium companies, i.e. the advancement of technology, the mass retirement of the baby boomer generation, and the ever more dynamically-changing values of the web-generation workforce. Dealing with bridging the skill gaps may deem to uproot the company paradigm and demand for a new and more efficient model. Is there a solution to reduce the growing pain of workforce renewal?
Continuous fibre (CF) aerospace preforms exhibiting excellent mechanical performance possess low formability characteristics and are confined to simple shell-like geometries with minimal curvatures. On the other hand, short fibre preforms such as randomly oriented strands (ROS) offer high formability but exhibit low mechanical performance. The manufacturing of composites involves time and huge costs.
The new generation of complex composites structures that will be developed by Hutchinson and its partners will integrate several functions, as esthetic interior panel, acoustic, thermal and vibration isolation, in addition to mechanical and robustness contribution brought by the integrated structure. These new technologies will allow to reduce the amount of parts, and also to reduce the amount of operations required to build an assembly, generating an energy saving in the global process.
Business aircraft seats are typically designed to provide maximum comfort to the occupant, while adhering to strict certification requirements. This tends to result in the designed seat becoming heavy and costly due to conservative tradeoff analysis, and a dependence upon legacy design techniques. With the advent of more powerful computer aided design techniques it is possible to design a seat that meets both the comfort requirements of the occupant, and strict regulatory requirements.
Ciena Corporation is a global supplier of telecommunications networking equipment. It develops this equipment in a high product mix, low volume environment. Due to this environment and the short cycle times of its products, the company has product categories, which are highly dynamic both in volume and number of customers. Ciena wishes to be more agile in managing its supply chain. It also wishes to better predict the dynamics of product volume and product end-of-life over short timeframes.
Modern air seeders in their simplest form involve an air supply system that receives granular product (seed and fertilizer) from a large holding tank, propels the product through several distribution lines, and delivers the product to the soil. Currently the conveying air runs faster than is usually required to reduce the risk of plugging. However, this results in wasted power in the air supply system, and also wasted inputs through either damage or misplacement.
