Report on industrial lands focus groups

87 pp. Bookmarks supplied by UO. Tables, appendices. Published July 15, 1998. Captured January 13, 2008.Davis & Hibbitts, Inc. (DHI) is pleased to present a summary of key points based on focus group research conducted for a consortium of organizations working on a regional industrial lands strategy. The purpose of the research was to solicit opinions about industrial land availability and industry location considerations from six perspectives â geographic, warehousing/ distribution, business park/flex space, manufacturing, large campus industrial, and land use/environment/agriculture. This focus group research is part of a larger, broader effort to reach consensus on an industrial lands strategy for the region. The Port of Portland is leading this planning effort, along with the Oregon Economic Development Department, Portland Development Commission, Columbia River Economic Development Council, Commercial Real Estate Economic Coalition, Metro, and Portland General Electric. The full report presents in much more detail the key ideas and themes that emerged from the discussions which may be useful in deciding what additional research and planning needs to be done. Because this was a qualitative study, the information describes, rather than quantifies, the variety of views among focus group participants.

Manufacturing Industrial Development for the Alternative Energy Systems-Final Report

NCMS identified and developed critical manufacturing technology assessments vital to the affordable manufacturing of alternative-energy systems. NCMS leveraged technologies from other industrial sectors and worked with our extensive member organizations to provide DOE with two projects with far-reaching impact on the generation of wind energy. In the response for a call for project ideas, 26 project teams submitted ideas. Following a detailed selection criteria, two projects were chosen for development: Advanced Manufacturing for Modular Electro-kinetic (E-K) Wind Energy Conversion Technology - The goal of this project was to demonstrate that a modular wind energy technology based on electrohydrodynamic wind energy principles and employing automotive heritage high volume manufacturing techniques and modular platform design concepts can result in significant cost reductions for wind energy systems at a range of sizes from 100KW to multi-MW. During this program, the Accio/Boeing team made major progress on validating the EHD wind energy technology as commercially viable in the wind energy sector, and moved along the manufacturing readiness axis with a series of design changes that increased net system output. Hybrid Laser Arc Welding for Manufacture of Wind Towers - The goal of this research program was to reduce the cost of manufacturing wind towers through the introduction of hybrid laser arc welding (HLAW) into the supply chain for manufacturing wind towers. HLAW has the potential to enhance productivity while reducing energy consumption to offset the foreign low-cost labor advantage and thereby enhance U.S. competitiveness. HLAW technology combines laser welding and arc welding to produce an energy efficient, high productivity, welding process for heavy manufacturing. This process leverages the ability of a laser to produce deep weld penetration and the ability of gas metal arc welding (GMAW) to deposit filler material, thereby producing stable, high quality, welds on joints with gaps and mismatches typical of those seen in heavy manufacturing. Wind towers utilize varying thicknesses of steel throughout their structures to meet the mechanical load requirements while keeping material costs low. A typical tower might have as many as twelve different material thicknesses. Joining each thickness requires a unique joint design and welding approach to enable the management of quality, productivity, and mechanical properties. In this program, laser joining of materials with thicknesses ranging from 12mm to 35mm were evaluated against the standard quality and mechanical requirements for General Electric wind tower components. The joining processes demonstrated showed the ability to meet key requirements with the appropriate process controls in place

Time resolution of the plastic scintillator strips with matrix photomultiplier readout for J-PET tomograph

Recent tests of a single module of the Jagiellonian Positron Emission Tomography system (J-PET) consisting of 30 cm long plastic scintillator strips have proven its applicability for the detection of annihilation quanta (0.511 MeV) with a coincidence resolving time (CRT) of 0.266 ns. The achieved resolution is almost by a factor of two better with respect to the current TOF-PET detectors and it can still be improved since, as it is shown in this article, the intrinsic limit of time resolution for the determination of time of the interaction of 0.511 MeV gamma quanta in plastic scintillators is much lower. As the major point of the article, a method allowing to record timestamps of several photons, at two ends of the scintillator strip, by means of matrix of silicon photomultipliers (SiPM) is introduced. As a result of simulations, conducted with the number of SiPM varying from 4 to 42, it is shown that the improvement of timing resolution saturates with the growing number of photomultipliers, and that the 2 x 5 configuration at two ends allowing to read twenty timestamps, constitutes an optimal solution. The conducted simulations accounted for the emission time distribution, photon transport and absorption inside the scintillator, as well as quantum efficiency and transit time spread of photosensors, and were checked based on the experimental results. Application of the 2 x 5 matrix of SiPM allows for achieving the coincidence resolving time in positron emission tomography of $\approx$ 0.170 ns for 15 cm axial field-of-view (AFOV) and $\approx$ 0.365 ns for 100 cm AFOV. The results open perspectives for construction of a cost-effective TOF-PET scanner with significantly better TOF resolution and larger AFOV with respect to the current TOF-PET modalities.Comment: To be published in Phys.

Intelligent control for energy-positive street lighting

The paper investigates the application of solar energy in public lighting for realizing a street lighting sub-grid with positive yearly energy balance. The focus is given to the central controller, which ensures the adaptive behavior of the overall system and provides smart city services to the end users via its web-based user interface. A functionality of the controller of special interest is the optimization of the energy management of the system, i.e., determining when to sell and buy electricity to/from the grid, in order to minimize the cost of electricity (or to maximize the profit) subject to a given, time-of-use variable energy tariff. This requires precise forecasts of the energy produced and consumed, as well as appropriate robust optimization techniques that guarantee that the system bridges potential power outages of moderate duration in island mode

Examining legitimatisation of additive manufacturing in the interplay between innovation, lean manufacturing and sustainability

In response to hypercompetition, globalisation and increasing consumer expectations, many manufacturing firms have embraced lean manufacturing (LM). The primary goal of LM is to reduce/eliminate waste (muda). There is broad consensus as to what constitutes waste, but not on LM implementation. Implementation is not prescriptive with each firm relying on a different combination of administrative, process and routine change/innovation. Lean manufacturing brings about incremental change relying on administrative, process and routine levers. It best fits mass production where process variability is low and demand is high and stable. Lean manufacturing can significantly reduce waste but not eliminate waste, and the attained benefits have not always lived up to expectations. Additive manufacturing (AM) promises to revolutionise manufacturing beyond recognition by eliminating or drastically removing the waste thereby achieving sustainability. But AM is at its formative stage – the space between the concept and growth - where many promising breakthrough technologies fail. To reach its full potential, it needs to achieve high-scale adoption. In this paper, we examine how AM can significantly reduce/eliminate waste and how it can deliver triple bottom line on an unprecedented scale. We contend that AM, if adopted deeply and widely, will take LM to its final frontier, but there are a number of impediments to this end. We identify legitimation as critical to its wide diffusion and develop a number of propositions expediting AM's legitimation. Legitimation of AM will ensure its deep and broad diffusion and should this happen, waste will be a thing of the past an important stride towards sustainable future
