Large-amplitude torsional oscillations in a nonlinearly suspended beam: A theoretical and numerical investigation

We consider the forced sine-Gordon equation on a bounded domain, which models the torsional oscillation of the main span of a suspension bridge. We use Leray-Schauder degree theory to prove that, under small external forcing, the undamped equation has multiple periodic solutions. Using physical constants from the engineers' reports of the collapse of the Tacoma Narrows Bridge, we solve the damped equation numerically and observe that multiple periodic solutions exist and that whether the span oscillates with small or large amplitude depends only on its initial displacement and velocity. Moreover, we observe that the qualitative properties of our solutions are consistent with the behavior observed at Tacoma Narrows on the day of its collapse. We also consider a nonlinear system which models the coupled vertical-torsional motion of the main span. Again, we prove the existence of multiple periodic solutions to the undamped system via a Leray-Schauder degree theory argument. We solve the damped system numerically and replicate the phenomena that were observed at Tacoma Narrows on the day of its collapse. 2001 ACKNOWLEDGEMENTS I wish to express my sincere gratitude to my major advisor, Joe McKenna.

Guide for SCAMPI Appraisals: Accelerated Improvement Method (AIM)

Abstract : The Software Engineering Institute's Accelerated Improvement Method (AIM) incorporates a new version of the Team Software ProcessSM (TSP SM) The Team Software Process Plus (TSP+). TSP+ is a project-based implementation of many of the specific and generic practices of Capability Maturity Model Integration (CMMI) for Development. Organizations using AIM for their improvement approach will be implementing similar processes with similar artifacts. Since these implementations of CMMI start from a common base, the work of appraising such organizations against a specific model scope should benefit from this commonality of approach. This document therefore provides guidance to lead appraisers and appraisal teams unfamiliar with TSP+ when conducting Standard CMMI Appraisal Method for Process Improvement (SCAMPISM) appraisals within organizations that use the TSP+ as a foundational operational practice. The intended benefits of this guidance are (1) to shorten the time needed to prepare and conduct such appraisals; (2) to provide information helpful for appropriate interpretations; (3) and to familiarize SCAMPI leads and appraisal teams with a powerful, proven, and available technology.
Comparative Assessment of Fuel-Based Systems for Space Heating

Replacing fossil fuels by biofuels and increasing energy efficiency are often considered to be options for reducing the net emission of greenhouse gases. This thesis presents the results of analyses of energy efficiency, emission and cost of whole energy system chains, from the natural resource to the end user when heating detached houses in a Swedish context. External costs and taxes of the energy systems were analysed. District heating using cogeneration, fuel-based electric heating and local boilers were considered. The electricity production was seen from a marginal perspective. The method and assumptions used are of great importance for the results. Therefore, a range of alternatives was analysed. The heat-pump and district-heating systems are found to be the most energy-efficient, followed by the local boiler systems. A reduction in the primary energy use typically leads to a reduction in emissions and cost. The wood-fuel-based systems emit about one tenth of the CO2 emitted by the fossil-fuel-based systems. CO2 sequestration does not reduce the CO2 emission from natural-gas-based systems to the low level of the wood-fuel-based systems and, in addition, makes the natural-gas-based systems more expensive than the wood-fuel-based systems. The fossil-fuel-based local boiler systems are found to be the most cost-efficient, followed by the heat-pump and district-heating systems. Systems based on natural gas are less expensive than the corresponding wood-fuel-based systems, but the difference in cost between the same types of wood-fuel- and fossil-fuel-based systems is less than 12%. External costs are highly uncertain, but applying external costs that were estimated based on a high cost level can make the wood-fuel-based systems the most cost-efficient. Taxes levied on all fossil-fuel-related emission and fuel use in the systems will tend to lower energy use and CO2 emission. Consumer electricity and heat taxes have an impact on the total cost, regardless of the fuel used, and benefit local boiler systems. (Less)

Rapid Differential Detection of H1 and H3 Subtype Swine Influenza Viruses by a TaqMan-MGB Based Duplex One-Step Real Time RT-PCR Assay

Swine influenza is not only an economically important respiratory disease in swine, but also constantly poses a threat to human health. Hence, developing a rapid, sensitive and efficient detection method of swine influenza virus (SIV) is highly essential. By aligning the HA gene sequences of SIV circulating in China in recent 10 years, a H1 primer-probe set targeting both Eurasian avian-like H1N1 (EA H1N1) and Pandemic 2009 H1N1 (Pdm09 H1N1) lineages plus a H3 prime-probe set targeting the prevalent human-like H3N2 (HL H3N2) subtype were designed, respectively. Further, a TaqMan-MGB based duplex one-step real time RT-PCR (RRT-PCR) assay was established and evaluated. The duplex RRT-PCR possessed the detection limit of 5 copies/μL HA plasmid for each of the EA H1N1, Pdm09 H1N1 and HL H3N2 subtype SIVs, and matched an overall detection sensitivity of 100% and specificity of 91.67% with traditional virus isolation through chicken embryo inoculation using experimentally infected mice lung samples. Besides, the method showed high repeatability both within-run and between-runs, and no cross-reactivity against some commonly circulated porcine viruses in China. Furthermore, the duplex RRT-PCR method revealed a relatively higher prevalent rate of H1 than H3 subtype SIV in 166 nasal swabs from pigs in some slaughterhouse during October ~ December, 2019. This developed assay could be very helpful for rapid differential detection and routine surveillance of EA H1N1, Pdm09 H1N1 and HL H3N2 subtype SIVs in China.
Saddle height positioning for triathletes ssing road cyclist methods

Triathlon is the combined sport of swimming, cycling, and running. Cycling is normally the longest portion of the race. Therefore, maintenance of comfort and efficiency while maintaining high power output is essential for success in the cycling portion. Several methods are currently used for determination of height for road cyclists. It has yet to be determined if these methods are applicable to triathletes. Because of the different geometry of a triathlon bicycle, the question remains whether road-saddle fitting techniques can be an applied and work for the triathlon bicycle. This thesis evaluated the participant’s current saddle height in addition to four different road-cycling fitting methods with regard to oxygen consumption while in an aerodynamic position on a triathlon-specific bicycle. It was determined that there was no statistically significant difference between the recreational male and female triathletes’ current saddle heights or those of the four different methods.
From fall-risk assessment to fall detection: inertial sensors in the clinical routine and daily life

Falls are caused by complex interaction between multiple risk factors which may be modified by age, disease and environment. A variety of methods and tools for fall risk assessment have been proposed, but none of which is universally accepted. Existing tools are generally not capable of providing a quantitative predictive assessment of fall risk. The need for objective, cost-effective and clinically applicable methods would enable quantitative assessment of fall risk on a subject-specific basis. Tracking objectively falls risk could provide timely feedback about the effectiveness of administered interventions enabling intervention strategies to be modified or changed if found to be ineffective. Moreover, some of the fundamental factors leading to falls and what actually happens during a fall remain unclear. Objectively documented and measured falls are needed to improve knowledge of fall in order to develop more effective prevention strategies and prolong independent living. In the last decade, several research groups have developed sensor-based automatic or semi-automatic fall risk assessment tools using wearable inertial sensors. This approach may also serve to detect falls. At the moment, i) several fall-risk assessment studies based on inertial sensors, even if promising, lack of a biomechanical model-based approach which could provide accurate and more detailed measurements of interests (e.g., joint moments, forces) and ii) the number of published real-world fall data of older people in a real-world environment is minimal since most authors have used simulations with healthy volunteers as a surrogate for real-world falls. With these limitations in mind, this thesis aims i) to suggest a novel method for the kinematics and dynamics evaluation of functional motor tasks, often used in clinics for the fall-risk evaluation, through a body sensor network and a biomechanical approach and ii) to define the guidelines for a fall detection algorithm based on a real-world fall database availability.

Development of Control Algorithms for a Humanoid Robot

This paper describes the work developed in a final course project, aiming at the development of control algorithms for a small-size humanoid robot using off-theshelf technologies. The main focus is placed on the implementation of low-level control strategies for both locomotion and balancing tasks. The main features of this implementation are the distributed control approach and the relevance given to the sensorial information. Some practical issues on servomotor control are given since that turned out necessary before entering higher levels of control. Particular attention is given to the low-level control of RC servomotors and the enhanced performance achieved by software compensation. The distributed set of controller units is the key element towards a control system that compensates for large changes in reflected inertia and providing position and velocity control. Furthermore, an intermediate local-level controller is implemented based on force sensing, providing robust and adaptive behaviour to changes in a slope surface.
An Interoperable Integration Model for Bluetooth Devices in the Internet of Things

The Internet of Things (IoT) provides the ability for humans and computers to interact with billions of devices such as sensors, actuators, and other objects connected to the Internet. Considering the consumer electronic market, one of the main adopted wireless network protocols is Bluetooth and, nowadays, the Bluetooth Low-Energy (BLE) version. Therefore, the development of new services that interact with BLE-enabled devices is an interest topic for IoT. Specially when considering BLE-enabled devices that uses GATT protocol for communication. In this paper is proposed a solution based on the use of a flow-based programming tool, Node-RED, that allows data provided by BLE-GATT devices to be available to Internet services in an easy to implement way using widely used protocols, such as MQTT. Also, regarding interoperability between devices, it is proposed the use of oneIoTa data model to allow standardized communication between BLE devices and Internet services. Therefore, the presented solution should easier the integration of BLE devices with Internet services, and keep interoperability using a public data model.
Next-Generation Sequencing Identi�es Potential Actionable Targets In Pediatric Sarcomas

BACKGROUND Pediatric bone and soft-tissue sarcomas represent 13% of all pediatric malignancies. International contributions to introduce next-generation sequencing (NGS) approaches into clinical application are currently developing. We present the results from the Precision Medicine program for children with sarcomas at a reference center. RESULTS Samples of 70 pediatric sarcomas were processed for histopathological analysis, RT-PCR and NGS with a consensus gene panel. Pathogenic alterations were reported and if existing, targeted recommendations were translated to the clinic. Seventy pediatric patients with sarcomas from 10 centers were studied. Median age was 11.5 years (range 1-18). Twenty-two (31%) had at least one pathogenic alteration by NGS. Thirty pathogenic mutations in 18 different genes were detected amongst the 22 patients. The most frequent alterations were found in TP53, followed by FGFR4 and CTNNB1. Eighteen actionable variants were detected and six patients received targeted treatment observing a disease control rate of 78%. Extrapolating the results to the whole cohort, 23% of the patients would obtain clinical bene�t from this approach. CONCLUSIONS Pediatric sarcomas have a different genomic landscape when compared to adult cohorts. Incorporating NGS targets into pediatric sarcomas’ therapy is feasible and allows personalized treatments with clinical bene�t in the relapse setting.
LOUISIANA PORT PRIORITY PROGRAM: AN APPLICATION OF BENEFIT-COST ANALYSIS TO PROJECT APPRAISAL

In this study Louisiana's Port Construction and Development Priority Program and the methodology utilized therein to evaluate capital investments are described. The program is designed to allocate state funds, with incentives for participation by public ports and the private sector. To ensure maximum participation by stakeholders, several measures were adopted at the program formulation stage, and continuing outreach efforts were made to assist ports throughout implementation of the program. The experience gained from operating this program is thought to be unique for several reasons: first, the multifaceted role of public ports both as commercial enterprises and as agents of economic development differs from the role of other public transportation providers, requiring adjustments in project appraisal methodology; second, competitive and cooperative postures among private and public port terminals raise unique policy dilemmas for public intervention in the market; and third, working with small to medium-size, semiautonomous local port authorities for program implementation requires various adjustments in policy prescriptions. Also discussed are the program provisions specifically designed to address these structural characteristics in the maritime sector. The evaluation methodology that was developed takes into account social, economic, environmental, and other impacts from the state's point of view. Over the initial 5-year period, 75 public port projects valued at about $166 million have been evaluated and funded. The program has been successful, with broad acceptance from public ports and the state legislature.
