This paper explores how a scaled aircraft can be used to model a full-scale aircraft sonic boom. All scales from 5 to 100% are investigated. To create a scaled pressure profile that represents the full-size aircraft, the Mach number, static margin, angle of attack, and canard incidence angle are set equal to the full-size aircraft's parameters. By setting these parameters, the scaled unmanned aircraft creates an F-function proportional to the square of the scaling ratio. To scale the acoustic advance, the propagation distance must be reduced. One way to accomplish this scaling is to fly at a lower altitude; however, to generate the proper wing loading, a pull-up maneuver must be performed. Alternatively, the subscale vehicle can be flown at the full-scale aircraft cruise altitude, and data are recorded at an intermediate altitude by a chase aircraft with a pressure probe. Using this method, the test aircraft properly models the shape of the full-scale aircraft sonic boom. The duration and overpressure of its sonic boom are respectively linearly and quadratically proportional to its scale. The lower bound in size is explored by considering manufacturing, data acquisition, and molecular relaxation. Copyright © 2011 by the American Institute of Aeronautics and Astronautics, Inc.

The following paper presents the concept of matching social network and corporate hierarchy in organizations with stable corporate structure. The idea allows to confirm whether social position of an employee calculated on the basis of the social network differs significantly from the formal employee role in the company. The results of such analysis may lead to possible company management improvement enabling to gain a competitive edge. In order to perform this task the authors have made experiments with the use of two real-life datasets: Enron and mid-sized manufacturing companies showing which social network metrics may be suitable to match organizational structure and social network with good results. © 2011 Springer-Verlag.

Advanced Steel Construction | Year: 2014
Over twenty six percent of the bridges in the United States are structurally deficient or functionally obsolete. Corrosion of steel used in structures like bridges and buildings is a problem that has gained increased interest and focused concern. Steel is often the metal that is preferred for use in such applications due to a synergism of ease of availability, acceptable mechanical properties and cost effectiveness. Through the years, titanium has grown in strength, stature and significance to be recognized as an emerging high performance metal that is both stronger and lighter than steel. A distinctive property of titanium and its alloys is its non-corrosive nature. However, a major drawback in the selection and use of pure titanium or its alloy counterpart is the prohibitively high cost. Therefore, it may be possible to combine steel and pure titanium and/or its alloy in structures by restricting steel for bulk of the structure and selectively using titanium and its alloys for the critical but low volume elements, such as, gusset plates and bearings. A hybrid use of titanium in conjunction with steel for structural members will result in better performance while concurrently proving to be both cost-effective and economically affordable. The synergistic use of structural steel and titanium in close proximity with each other could result in accelerated corrosion of steel in the immediate vicinity of titanium. The corrosion performance of titanium plates coupled with steel members is presented. A few viable strategies for minimizing galvanic coupling effects between steel and titanium are discussed. Corrosion experiments were conducted to measure the severity of corrosion when titanium and steel form a galvanic couple, and copper and steel was a comparative system. The study revealed that adequate precautions are needed to minimize localized corrosion when titanium gusset plates are coupled with structural steel members.

In the last few years, the collaboration between research institutions and industry has become a well established process. Transfer of Knowledge (ToK) is required to accelerate the development of both sides and to enable them to unlock their full potential. European Commission within the Marie Curie Industry and Academia Partnerships & Pathways (IAPP) programme supports the cooperation between these two sectors at the international scale by funding research projects that as one of the objectives aim at enhancing human mobility. IAPP projects offer people from different institutions the possibility to move sector and country in order to provide, absorb and implement new knowledge in a professional industrial-academic environment. In this paper, one of such projects is presented and both academia and industry perspectives in regard to opportunities and challenges in Transfer of Knowledge are described. Computational Intelligence Platform for Evolving and Robust Predictive Systems (INFER) is the IAPP project that serves as a case study for this paper. © Springer-Verlag Berlin Heidelberg 2013.
News Article | April 13, 2016
Last fall, the Ford Motor Company announced a $4.5 billion investment in EV and battery R&D, and now the company has upped the ante on itself. For the first time since the 1950s, Ford is embarking on a complete do-over of its product operations and global headquarters in Dearborn, Michigan, that seems aimed at soaking the entire company in EV culture. The effort will transition the company’s current roster of 70 buildings into two “green” campuses that will double as showcases and test beds for cutting edge mobility products, much of which revolves around EV technology and connectivity. And yes, Ford’s eBikes will be part of it. First things first — it’s true, Ford eBikes are a thing. In January CleanTechnica visited the North American International Auto Show in Detroit as a guest of Ford, which provided the opportunity to pepper Dr. Ken Washington, the company’s VP for Research and Advanced Engineering, with questions about Ford’s recent ventures into pedal-power. The answer was “very serious.” In fact, e-bikes were one of only two mobility solutions that made the cut for particular attention from Ford, after the company explored more than a score of other mobility options for marketing potential (the other area of focus is non-traditional/shared vehicle ownership). So, the new Product Campus will serve as a pilot location enabling Ford to test out its Ford-branded eBike in action, along with autonomous vehicles and on-demand shuttles. The Product Campus is also designed as an all-weather walkable community — an important consideration for chilly Michigan winters — so covered walkways are featured along with trails and biking/walking paths. Of course, for the foreseeable future, the bulk of Ford’s products will run on liquid fuel (fossil petroleum or biofuel), but the new Product Campus will pickle many of the company’s 30,000 employees in EV culture by focusing on sustainability. We’re calling it EV culture because after all, the whole point of the EV revolution is to make things better. Ford is extending that concept past simply reducing airborne air pollutants, to include overall health and wellness as well as new mobility options that have the potential to embrace populations far beyond the car-owning public. The new Product Campus replaces the 1953 Research and Engineering Center… That roundish building near the foreground sports a rooftop full of solar panels. That’s clearly not enough to power the whole campus, but it’s a start. The main sustainable energy technology is geothermal heating and cooling. Construction is beginning this month, with completion slotted for 2023. The other campus will preserve the iconic Ford World Headquarters building, but update its surroundings to encourage walking and biking. The company will renew its commitment to the 1960s era Arjay Miller Arboretum at the site, and focus on native plantings and more green space throughout. Renovations are expected to begin in 2021. Overall, the two campuses are not striving for the highest level in LEED building energy efficiency standards, most likely due to the unique demands of functional operations. However, the company is aiming for at least Gold certification, partly through energy savings: …increased building insulation, new glazing systems, state-of-the-art lighting and daylighting, and heat recovery will reduce overall energy use in new buildings by approximately 50 percent annually. Rainwater capture and treatment is also a main feature at both campuses, along with smart metering and high efficiency fixtures to reduce potable water use. Rainwater retention areas and lavish tree canopies are also part of the water management plan. With an eye on future improvements, the plans include a net-zero waste, energy, and water Sustainability Center that goes beyond LEED to meet the Living Building Challenge for net zero construction. The challenges of true net-zero construction can be daunting, and they include health issues such as indoor air quality. However, it seems that Ford already has a head start on ensuring that the wellness of building occupants is a major feature of the Sustainability Center. The designer of the new campuses, SmithGroupJJR, already has an impressive stock of green projects under its belt, and has incorporated the WELL Building Standard® into its design.
