Study of roles of remote manipulator systems and EVA for shuttle mission support, volume 1

Alternate extravehicular activity (EVA) and remote manipulator system (RMS) configurations were examined for their relative effectiveness in performing an array of representative shuttle and payload support tasks. Initially a comprehensive analysis was performed of payload and shuttle support missions required to be conducted exterior to a pressurized inclosure. A set of task selection criteria was established, and study tasks were identified. The EVA and RMS modes were evaluated according to their applicability for each task and task condition. The results are summarized in tabular form, showing the modes which are chosen as most effective or as feasible for each task/condition. Conclusions concerning the requirements and recommendations for each mode are presented

Development and validation of methods for man-made machine interface evaluation

The alternate methods of conducting a man-machine interface evaluation are classified as static and dynamic, and are evaluated. A dynamic evaluation tool is presented to provide for a determination of the effectiveness of the man-machine interface in terms of the sequence of operations (task and task sequences) and in terms of the physical characteristics of the interface. This dynamic checklist approach is recommended for shuttle and shuttle payload man-machine interface evaluations based on reduced preparation time, reduced data, and increased sensitivity of critical problems

Multifunctional Agriculture, Quality of Life and Policy Decisions: an Empirical Case

The TOP-MARD research project (Toward a Policy Model of Multifunctional Agriculture and Rural Development), that will be here described in its Italian version, links farmers’ behaviour with their economic, social and environmental effects, showing the difference between a behaviour guided by market profitability only and one guided by the interest of a broader social group. It was financed by EU in 11 European countries, and it took place in 2006-2008. The TOP-MARD research defined a 10-modules model (POMMARD), that links use of land and production techniques to several dimensions of a context (quantitative and qualitative, from economic to social and environmental) and to the quality of life of its population. STELLA, a Systems Thinking software, has been used in order to develop the POMMARD model. The POMMARD model is partially supply-driven with demand constraints: land use and its dynamics produce a mix of marketable and non-marketable goods, that impact other sectors and the territory through an I-O or a SAM, and through the consequences of their production on the quality of life. Labour requirements and demography can produce – therefore – immigration, and contribute to job creation and dynamics. Public intervention influences local resources and human behaviour. Farmers can choose their style of production and land use, that are the “key drivers” of change: when land is converted from a land use to another or from a conventional to a non-conventional style of production, there occurs a change in the vector of inputs (means of production and workers) and in the vector of outputs, that also comprehends public goods. Provision of public goods increases the quality of life. Rural areas become therefore more attractive to younger generations, encouraging them to stay rather than migrate, and attracting new-comers. Tourism can also be influenced by the attractiveness of the area, which can contribute further income, within the limits of tourism capacity and seasonality. Starting from the actual systematic links, the model considers the main variables (population, income, …) under different policy scenarios: providing suggestions to policy makers about the possible effects of exogenous shocks, such as policy measures, on rural development and quality of life.Multifunctional Agriculture, Quality of Life, Policy Decision., Agribusiness, Agricultural and Food Policy, Community/Rural/Urban Development, Food Consumption/Nutrition/Food Safety, Labor and Human Capital,

Actualizing agency through smart products: Smart materials and metaphors in support of the ageing population

Technological innovation is increasingly contributing to the development of Smart Products- SPs-, meant as autonomous devices augmented by sensing, processing and network capabilities. Given the reduced familiarity that the ageing population has with technological products, it is deemed appropriate to deploy SPs to enhance the experience with technologies of this population segment. Recent studies in interaction design demonstrate how analogies and metaphors, powerful learning tools for written, verbal and visual communication, can be physically embedded into products to improve the interaction with the users. Metaphors, that can trigger established knowledge domains, allow users to create bridges between old and new products making the product more intuitive. This study proposes that Smart Materials (SMs) may be more successful for embedding multi-sensorial metaphors into novel SPs, increasing the chance of adoption among ageing users. A novel device has been designed using four different SMs families in order to evaluate which design would be more intuitive among the users. 62 participants (N=31 under-60 years-old and N=31 over-60 years-old) assessed the 32 interactions designed. Findings reveal how age impacts the selection of the preferred interaction and how SMs can embed metaphors to support the users re-establishing their own subjective awareness, hence control, of the world around them.This research study has been supported by the EU-funded FP7 collaborative research project Light.Touch.Matters (LTM), under agreement n°31031

Evaluation of lens distortion errors in video-based motion analysis

In an effort to study lens distortion errors, a grid of points of known dimensions was constructed and videotaped using a standard and a wide-angle lens. Recorded images were played back on a VCR and stored on a personal computer. Using these stored images, two experiments were conducted. Errors were calculated as the difference in distance from the known coordinates of the points to the calculated coordinates. The purposes of this project were as follows: (1) to develop the methodology to evaluate errors introduced by lens distortion; (2) to quantify and compare errors introduced by use of both a 'standard' and a wide-angle lens; (3) to investigate techniques to minimize lens-induced errors; and (4) to determine the most effective use of calibration points when using a wide-angle lens with a significant amount of distortion. It was seen that when using a wide-angle lens, errors from lens distortion could be as high as 10 percent of the size of the entire field of view. Even with a standard lens, there was a small amount of lens distortion. It was also found that the choice of calibration points influenced the lens distortion error. By properly selecting the calibration points and avoidance of the outermost regions of a wide-angle lens, the error from lens distortion can be kept below approximately 0.5 percent with a standard lens and 1.5 percent with a wide-angle lens

Romantic relationships at the beginning of emerging adulthood. Some antecedents and correlates of satisfaction with romantic partners

Se exploró el lugar que ocupa la pareja en la red de vínculos íntimos en una muestra aleatoria de 400 jóvenes argentinos estudiados desde los 14-16 hasta los 18-21 años. A comienzos de la adultez emergente casi la mitad tenía una pareja amorosa; en dicho grupo, el novio/a era, por primera vez, la principal fuente de admiración, intimidad (junto al amigo/a íntimo) y amor (al mismo nivel que la madre) en el Inventario Red de Relaciones de Furman y Buhrmester. Sin embargo, los vínculos familiares y con el mejor amigo se veían como más duraderos que la relación de pareja. En coincidencia con la postura de que los distintos lazos íntimos se suman y complementan más que compiten entre sí, tener o no una pareja no mejoraba ni empeoraba la percepción de los vínculos con la familia y con el mejor amigo. De acuerdo con la continuidad entre la relación con los padres y con la pareja postulada por la teoría del apego, una relación amorosa menos satisfactoria se asociaba con peores relaciones contemporáneas con padre, madre, hermana/o y mejor amigo, por un lado, y con mayor violencia de ambos padres hacia el hijo a lo largo de la adolescencia, por el otroThe place of romantic partners in the network of close relationships was explored in a random sample of 400 Argentinean young people followed up from 14-16 to 18-21 years old. At the beginning of emerging adulthood almost half of them had a romantic partner and among this group, boy/girl friends were rated as first providers of admiration, intimacy (tied with best friends) and love (tied with mothers) on Furman and Buhrmester’s Network of Relationships Inventory, for the first time. Bonds with family members and best friends, however, were rated higher on reliable alliance than the romantic bond. The fact that having or not a romantic partner neither improved nor worsened the quality of relationships with parents, siblings and best friends suggests that different close relationships are elements of an expanding network in which their influences are complementary rather than conflicting. In line with the continuity between parent and romantic relationships proposed by attachment theorists, those less satisfied with their romantic relations were less satisfied with their contemporaneous bonds with mother, father, sibling and best friend, on the one hand, and had undergone more parental violence across adolescence, on the other hand.Fil: Facio, Alicia Cristina.

Envisioning a Post-Conflict Tripoli: The Inclusive Urban Strategy and Action Plan for Bab Al-Tabbaneh and Jebel Mohsen

The Inclusive Urban Strategy and Action Plan is a study conducted by a multi-disciplinary international team focused on the post-conflict area of Tripoli, the second largest city of Lebanon. The project includes the neighbourhoods of Bab Al-Tabbaneh and Jebel Mohsen and the conflict zone in between where hostilities ended thanks to the implementation of a security plan in 2014. The aim of the proposal is to initiate and foster peace and reconciliation between the conflicting communities, while addressing spatial, social and economic segregations by a holistic and tactical urban approach.The strategy results from a deep study and understanding of the actual fragile conditions in Tripoli, and derives its guidelines from the fractures and the intrinsic resources of the place. It is structured in three main layers (urban armature, functional injections and placemaking) and envisions the possibility to establish new relations and synergies inside the hugely fragmented environment.Instead of proposing concrete solutions, the strategy aims at initially generating the necessary conditions to trigger processes of recovery and therefore development, encountering positive outcomes and opportunities as well as possible threats. Adaptability and retrofitting thus became keywords in developing a realistic strategy that can take into consideration the difficulty of programming and making decisions in the context of post-conflict reconstruction

Use of infrared telemetry as part of a nonintrusive inflight data collection system to collect human factors data

The objective of this paper is to present a methodology and rationale for development of a Nonintrusive Inflight Data Collection System (NIDCS) to collect Human Factors (HF) data during a space mission. These data will enable the research team to identify and resolve issues. This paper will present the background and history of the NIDCS, the methodology and techniques employed versus those in current use on Earth, initial results of the effort--including a brief description of the equipment, and, finally, a discussion of the scientific importance and possible future applications of this system elsewhere. The schema for the NIDCS includes a collection of three types of data: behavioral, physiological, and biomechanical. These will be collected using videotape of crew members' activities, bioelectric signal measurement, and measurement of kinematics and kinetics, respectively. This paper will focus on the second type of data, physiological activity as determined by changes in bioelectric potentials as crew members perform daily assignments

Valence band excitations in V_2O_5

We present a joint theoretical and experimental investigation of the electronic and optical properties of vanadium pentoxide. Electron energy-loss spectroscopy in transmission was employed to measure the momentum-dependent loss function. This in turn was used to derive the optical conductivity, which is compared to the results of band structure calculations. A good qualitative and quantitative agreement between the theoretical and the experimental optical conductivity was observed. The experimentally observed anisotropy of the optical properties of V_2O_5 could be understood in the light of an analysis of the theoretical data involving the decomposition of the calculated optical conductivity into contributions from transitions into selected energy regions of the conduction band. In addition, based upon a tight binding fit to the band structure, values are given for the effective V3d_xy-O2p hopping terms and are compared to the corresponding values for alpha'-NaV_2O_5.Comment: 6 pages (revtex),6 figures (jpg
