Development of an urban health and wellbeing index for work precincts: A comparative study in Sydney, Australia

Work precincts are recognized for their significant role as generators of employment and associated commerce within urban areas. This study describes a method for analyzing the physical characteristics of urban work precincts in promoting the health and wellbeing of their occupants. The following physical parameters are analyzed: public transport accessibility, green and blue spaces, food environments, fitness facilities, supermarkets, and grocery stores. The parameters are assessed using quantitative spatial analysis based on street network data, as well as point of interest data acquired from OpenStreetMap (OSM). The streets and their intersections are stored in the OSM database as links and nodes, respectively. The evaluation of the performance metrics involves measuring the street network distance from each node to the closest node of interest for each parameter. The metrics are then combined, forming an urban health and wellbeing index (UHWI), which can be used to compare the performance of different precincts. The method was tested by investigating four work precincts in Sydney, Australia, all hosting a large office building belonging to the same business institution. Our results identified two of the four precincts with a high UHWI and resulted in the identification of one underperforming precinct

Radiation Tolerance of CMOS Monolithic Active Pixel Sensors with Self-Biased Pixels

CMOS Monolithic Active Pixel Sensors (MAPS) are proposed as a technology for various vertex detectors in nuclear and particle physics. We discuss the mechanisms of ionizing radiation damage on MAPS hosting the the dead time free, so-called self bias pixel. Moreover, we discuss radiation hardened sensor designs which allow operating detectors after exposing them to irradiation doses above 1 Mra

Double pion production in np and pp collisions at 1.25 GeV with HADES

The results of double pion production in np and pp collisions at an incident beam energy of 1.25 GeV with the HADES spectrometer at GSI are presented. The np-reactions were studied in d p collisions at 1.25 GeV/u using Forward Wall hodoscope aimed at registering spectator protons. High statistic invariantmass and angular distributions are obtained within the HADES acceptance which are compared with phase-space distributions

Resonance production in p+p, p+A and A+A collisions measured with HADES

The knowledge of baryonic resonance properties and production cross sections plays an important role for the extraction and understanding of medium modifications of mesons in hot and/or dense nuclear matter. We present and discuss systematics on dielectron and strangeness production obtained with HADES on p+p, p+A and A+A collisions in the few GeV energy regime with respect to these resonances

New data on the differential cross section of the dp-elastic scattering at 2.5 GeV obtained with HADES detector

New results on the differential cross section in deuteron-proton elastic scattering are obtained at the deuteron kinetic energy of 2.5 GeV with the HADES spectrometer. The angular range of 69°-125° in the center of mass system is covered. The obtained results are compared with the relativistic multiple scattering model calculation using the CD-Bonn deuteron wave function. The data at fixed scattering angles in the c.m. are in qualitative agreement with the constituent counting rules prediction

Investigation about the influence of the mechanical properties of lead core and brass jacket of a NATO 7.62 mm ball bullet in numerical simulations of ballistic impacts

In the present work a validated numerical approach has been used in order to build a robust and reliable FE model of the impact of a NATO 7.62 mm ball bullet, against an aluminium transmission shaft. The bullet is a full metal jacket type, with a lead alloy core and a brass jacket. Target shaft is made by an Al6061-T6 aluminium alloy. According to the soft core (lead alloy) of the bullet, most effort has been spent in order to evaluate the effect of bullet materials mechanical properties on the numerical results. Numerical analyses, carried out using the non-linear dynamic finite element solver Abaqus∖Explicit 6.10, have been performed focusing on core and jacket material behaviour (target material, Al6061-T6, has been previously calibrated by the authors). Thus numerical analyses have been performed considering for the mechanical behaviour of the bullet both a simplified approach (as reported in literature) and new material data (with strain rate effect) obtained by means of experimental tests on the two materials (lead and brass) with specimens cut directly from the bullet. Finally the results of the analyses have been compared with real experimental ballistic tests

Real-time interactive multimodal systems for physiological and emotional wellbeing

There has been lately significant progress in the design of clinically assistive technologies for physiological and emotional wellbeing, driven by developments in Human Computer Interaction, Virtual Reality systems for rehabilitation and social interaction and Rehabilitation Robotics. The clinical, task-driven nature of such systems though often affects negatively the user acceptance of technology, resulting in lesser interactions with the user. At the same time, interactive environments which are not constructed for strictly medical applications, can also instigate interaction dialogues which generate physiological and emotional benefits for the user, while also incorporating a more playful dimension. As there is currently lack of communication channels between Clinically Assistive technologies and Socially Interactive Design Systems, the chapter attempts to merge these domains by identifying parameters related to physiological and emotional wellbeing that could inform the design of interactive systems for health and wellbeing at variable scales. These parameters are presented as a set of guidelines for Interaction design for healthcare and wellbeing, and the chapter elaborates on their practical application through three case studies: RoboZoo, Textrinium and Reflectego. All the presented case studies operate as public indoor or outdoor installations and have been tested in different contextual conditions, in Netherlands, Spain and France
