Hybrid-Wing-Body Vehicle Composite Fuselage Analysis and Case Study

Recent progress in the structural analysis of a Hybrid Wing-Body (HWB) fuselage concept is presented with the objective of structural weight reduction under a set of critical design loads. This pressurized efficient HWB fuselage design is presently being investigated by the NASA Environmentally Responsible Aviation (ERA) project in collaboration with the Boeing Company, Huntington Beach. The Pultruded Rod-Stiffened Efficient Unitized Structure (PRSEUS) composite concept, developed at the Boeing Company, is approximately modeled for an analytical study and finite element analysis. Stiffened plate linear theories are employed for a parametric case study. Maximum deflection and stress levels are obtained with appropriate assumptions for a set of feasible stiffened panel configurations. An analytical parametric case study is presented to examine the effects of discrete stiffener spacing and skin thickness on structural weight, deflection and stress. A finite-element model (FEM) of an integrated fuselage section with bulkhead is developed for an independent assessment. Stress analysis and scenario based case studies are conducted for design improvement. The FEM model specific weight of the improved fuselage concept is computed and compared to previous studies, in order to assess the relative weight/strength advantages of this advanced composite airframe technolog

Form Based Codes and Economic Impacts: A Multivariate Regression Analysis and Case Study

After a 100-year history, traditional zoning practices are being challenged as a contributing factor in a number of social, heath and economic problems facing cities in the United States. In this context, form based codes have emerged as a possible alternative way for cities to guide development. Growing out of the New Urbanist movement, form based codes frequently mix uses, allow for a greater variety of housing types and encourage development that is both denser and more compact. Despite an established literature which links land-use regulations, and zoning in particular, to fiscal outcomes, the impacts that form based codes have on public finance in the growing number of cities which have adopted them has yet to be fully investigated. The goal of this research is to examine if and how form based codes alter property tax and sales tax generation in the cities that adopt them. To examine the relationship between form based codes and public finance a series of two multivariate regression analyses were conducted using historic property and sales tax data. The first regression analysis was performed using the full list of 122 cities which have adopted form based standards from between 1984 and 2009. In an attempt to limit the diversity of sample cities and improve the ability to generalize results a second regression analysis was performed using a smaller list of 47 cities with populations between 50,000 and 200,000 thousand that had adopted form based standards between 1984 and 2009. The results of the first analysis established that a statistically significant positive relationship existed between the presence of form based standards which were implemented citywide and observed property tax revenue both in total and on a per capita basis. Similarly, a statistically significant positive relationship between the presence of form based standards implemented at the neighborhood level and total property tax revenue was observed. No significant relationship was found between the presence of neighborhood level standards and per capita property tax revenue. Further no significant relationship was found between form based standards and sales tax revenue. In general, these findings support the theory that form based codes and the development they allow, does alter the amount of property tax a city collects, but does not support the theory that form based codes affect sales tax revenues by facilitating the development of a more conducive urban, walkable environment or for any other reason. The results of the second regression analysis using data from cities with populations between 50,000 and 200,000 showed a significant positive relationship between the presences of citywide form based standards and total property tax revenue and per capita property tax revenue. Analysis of sales tax data showed a positive relationship between total sales tax revenue and the presence of form based standards at the neighborhood level. No other significant relationship between form based standards and sales tax revenue was observed. Similar, to analysis of all cities, the results for cities with population of 50,000 to 200,000 support the theory that form based codes and the development they allow does alter the amount of property tax a city collects, and that form based codes do not affect sales tax revenues except in the case of codes adopted at the neighborhood level, where a generally positive relationship was identified at the 10% confidence interval. Following this multivariate regression analysis, a case study of Saratoga Springs, New York was completed. Located in the far reaches of the Albany Metropolitan Area, Saratoga Springs developed as a popular tourist destination in the mid 1800’s. After experiencing economic decline in line with that of its peer cities in the mid to late 20th century, Saratoga Springs has experience a boom and now boast some of the highest home values in Upstate New York. In 2003 the city was one of the first in country to adopt form based standards, which have guided a significant amount of development in the city’s historic downtown as the city re-emerged as a popular tourist destination. Since the adoption of form based standards in Saratoga Springs both property tax and sales tax receipts have doubled

Developing a model of mental health self-care support for children and young people through an integrated evaluation of available types of provision involving systematic review, meta-analysis and case study

Background The mental health of children and young people (CYP) is a major UK public health concern. Recent policy reviews have identified that service provision for CYP with mental health needs is not as effective, responsive, accessible or child-centred as it could be. Following on from a previous National Institute for Health Research (NIHR) study into self-care support for CYP with long-term physical health needs, this study explored self-care support’s potential in CYP’s mental health. Objectives To identify and evaluate the types of mental health self-care support used by, and available to, CYP and their parents, and to establish how such support interfaces with statutory and non-statutory service provision. Design Two inter-related systematic literature reviews (an effectiveness review with meta-analysis and a perceptions review), together with a service mapping exercise and case study. Setting Global (systematic reviews); England and Wales (mapping exercise and case study). Participants (case study) Fifty-two individuals (17 CYP, 16 family members and 19 staff) were interviewed across six sites. Main outcome measures (meta-analysis) A measure of CYP’s mental health symptomatology. Data sources (literature reviews) MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, All Evidence-Based Medicine (EBM) Reviews, Applied Social Sciences Index and Abstracts (ASSIA) and Education Resources Information Center (ERIC). Review methods Titles and abstracts of papers were screened for relevance then grouped into studies. Two independent reviewers extracted data from studies meeting the inclusion criteria. A descriptive analysis and meta-analysis were conducted for the effectiveness review; descriptive analyses were conducted for the perceptions review. These analyses were integrated to elicit a mixed-methods review. Results Sixty-five of 71 included studies were meta-analysable. These 65 studies elicited 71 comparisons which, when meta-analysed, suggested that self-care support interventions were effective at 6-month [standardised mean difference (SMD) = −0.20; 95% confidence interval (CI) −0.28 to −0.11] and 12-month (SMD = −0.12; 95% CI −0.17 to −0.06) follow-ups. However, judged against Cochrane criteria, the studies were mostly low quality. Key elements of self-care support identified in the perceptions review were the acquisition of knowledge and skills, peer support and the relationship with the self-care support agent; CYP also had different perceptions from adults about what is important in self-care support. The mapping exercise identified 27 providers of 33 self-care support services. According to the case study data, effective self-care support services are predicated on flexibility; straightforward access; non-judgemental, welcoming organisations and staff; the provision of time and attention; opportunities to learn and practise skills relevant to self-care; and systems of peer support. Conclusions Mental health self-care support interventions for CYP are modestly effective in the short to medium term. Self-care support can be conceptualised as a process which has overlap with ‘recovery’. CYP and their families want choice and flexibility in the provision of such interventions and a continued relationship with services after the nominal therapy period. Those delivering self-care support need to have specific child-centred attributes. Future work Future work should focus on under-represented conditions (e.g. psychosis, eating disorders, self-harm); the role of technology, leadership and readiness in self-care support; satisfaction in self-care support; the conceptualisation of self-care support in CYP’s mental health; and efficacy and cost-effectiveness

Current approaches to the development of airport retail : a sales performance analysis and case study

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2002.Includes bibliographical references (leaves 43-45).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.During the 1990s, a number of airports around the United States radically changed the way they managed the retail space in their terminals. Departing from the traditional master concessionaire/operator model, airports began experimenting with branded direct leasing programs and outsourcing to third party developers. Serving over 700 million domestic airline passengers annually, and until recently overlooked by the retail development community at large, the airport network presents a significant market for retail development. We review the issues surrounding airport retail management, the genesis of the branded, mall- style and developer-run programs, and evaluate the relative performance of different management models both quantitatively and qualitatively, based on recent sales data and case studies of a number of airports. Data for this report was collected June/July 2002 in the form of publicly available data from industry trade groups and journals, interviews with members of airport business offices, developers active in airport retail, and firms providing concessionaire service to airports.by Ahron B.

A heuristic explicit model predictive control framework for Eco-trajectory planning: Theoretical analysis and case study

The trajectory planning problem (TPP) has become increasingly crucial in the research of next-generation transportation systems, but it presents challenges due to the non-linearity of its constraints. One specific case within TPP, namely the Eco-trajectory Planning Problem (EPP), poses even greater computational difficulties due to its nonlinear, high-order, and non-convex objective function. This paper proposes a heuristic explicit predictive model control (heMPC) framework to address the eco-trajectory planning problem in scenarios without lane-changing behavior. The heMPC framework consists of an offline module and an online module. In the offline module, we build an optimal eco-trajectory batch by optimizing a series of simplified EPPs considering different system initial states and terminal states, which is equivalent to the lookup table in the general eMPC framework. The core idea of the offline module is to finish all potential optimization and computing in advance to avoid any form of online optimization in the online module. In the online module, we provide static and dynamic trajectory planning algorithms. Both algorithms greatly improve the computational efficiency of planning and only suffer from a limited extent of optimality losses through a batch-based selection process because any optimization and calculation are pre-computed in the offline module. The latter algorithm is also able to face possible emergencies and prediction errors. Both theoretical analysis and numerical are shown and discussed to test the computational quality and efficiency of the heMPC framework under a mixed-traffic flow environment that incorporates human-driving vehicles (HDV) and connected and automated vehicles (CAV) with different market penetration rates (MPR)
