A Technology Survey Of Emergency Recovery And Flight Termination Systems For Uas, Richard Stansbury, Wesley Tanis, Timothy Wilson

Richard Stansbury

For safe flight in the National Airspace System (NAS), either under the current interim rules or under anticipated longer-term regulatory guidelines facilitating unmanned aircraft system (UAS) access to the NAS, the UAS must incorporate technologies and flight procedures to ensure that neither people nor property in the air, on the ground, or on or in the water are endangered by the failure of an onboard component, by inappropriate unmanned aircraft (UA) response to pilot commands, or by inadvertent entry by the UA into prohibited airspace. The aircraft must be equipped with emergency recovery (ER) procedures and technologies that ensure that …

Automatic Detection Of Slip-Induced Backward Falls, Jian Liu, Thurmon E. Lockhart

Jian Liu

Falls are the leading cause of injury deaths among people 65 years and older. The National Safety Council reported that in 2005, 17,700 Americans met their death by falling, and of these deaths, the majority (over 80%) were people over 65 years of age [1]. It is certainly desirable to avoid the fall accidents altogether through developing a comprehensive fall prevention program [2]. However, in case of unavoidable falls, an effective injury-prevention technology is critical to minimize/reduce fall-related physical injuries. Recently, the concept of wearable airbag [3] emerged as one viable and promising injury-prevention approach.

Supply System’S Technology Configuration As A Contributor To End-User Vulnerability, Lindsay Robertson, Katina Michael, Albert Munoz

Professor Katina Michael

Individuals requiring goods and services essential to their mode of living, are increasingly vulnerable to failures of the complex, interlinked, and inhomogeneous technological systems that supply those needs. Extant analysis techniques do not adequately quantify, from an end-user’s perspective, the vulnerability that is contributed by such technological systems. This study explores the significance of inherent weaknesses of inhomogeneous technological systems and proposes an approach for measuring vulnerability as the individual end-user ‘exposure level’ for each service. The measure of "exposure" that is developed, is mapped directly from the configuration of a technological system. This measure of exposure allows quantitative evaluation …

Permeable Reactive Barrier (Prb) Technology: An Innovative Solution For The Remediation Of Acidic Groundwater From Acid Sulphate Soil (Ass) Terrain, Laura Banasiak, Buddhima Indraratna

Laura J Banasiak Dr

The remediation of acidic groundwater contaminated with potentially toxic metals such as aluminium (Al) and iron (Fe) resulting from the oxidation of sulphidic materials in acid sulphate soils (ASSs) is a challenging geo-environmental problem that requires innovative engineering solutions. In low-lying coastal floodplains, the remediation strategies of groundwater manipulation (e.g. fixed-level weirs) and tidal buffering (e.g. two-way modified floodgates) are not feasible due to the risk of flooding during heavy rainfall events and their inability to prevent pyritic oxidation. In view of this in 2006, the first pilot subsurface permeable reactive barrier (PRB) using recycled concrete for the remediation of …

Increasing National Space Engineering Productivity And Educational Opportunities Via Intrepreneurship, Entrepreneurship And Innovation, Jeremy Straub

Jeremy Straub

Research and educational efforts related to space engineering or requiring access to space face significant startup costs. The cost of developing a 1-U (10 cm × 10 cm × 11 cm) CubeSat from scratch can be approximately $250,000. Those buying a kit must pay amortized vendor development costs on a per-mission basis, creating a lower per-mission barrier. Kit users are also constrained by being unable to make changes to vendor subsystems without incurring substantial redevelopment costs or vendor charges. The Open Prototype for Educational NanoSats (OPEN) is changing this by providing freely available design documents for a 1-U CubeSat class …
