No full textEfficient Urban Coverage for Relay Aided Smart Energy Wireless Networks
No full textPower grids deployed in every city worldwide have served relatively well in providing power supply of electricity. Nevertheless, today a new set of challenges is arising, such as the depletion of primary energy resources, the diversification of energy generation and the climate change. Traditional power grids are rapidly evolving into a new form under the name of smart grids, which encompass new technologies to meet the specific application requirements such as costs savings and energy efficiency. The key elements of this revolution are (i) the smart meters, i.e., devices which include communications and computations capabilities and are able to form a distributed network, and (ii) on purposely designed relay nodes, placed in strategic locations, to guarantee the necessary network coverage for the delivery of the report measurements to a central processing and decision unit. In this paper we propose the use of a ray tracing model for network planning, to support such an efficient coverage of relay nodes in a real urban use case. Preliminary results show accurate radio coverage estimations using different frequency bands, which has the potential to pave the way to the massive usage of smart grid networks
AI-Assisted GIS Toward GEO-AI: Trends and Innovations Overview
No full textThis paper explores the convergence of Geographical Information System (GIS) and Artificial Intelligence (AI) in the current context. While GIS has revolutionised geospatial information management and analysis, AI has opened new frontiers in advanced data processing and forecasting. This technological synergy offers unprecedented opportunities for policymakers to understand and shape (smart) communities in more effective, sustainable and liveable ways. The paper delves into the transformative impact of AI and geodata, exploring applications, benefits and challenges, and future prospects. The intersection of GIS and AI is giving rise to emerging trends that promise to transform the way we perceive and use Geographic Information (GI)
Occupational risks in grocery stores
No full textConclusions: Musculoskeletal disorders continue to be the most recurrent health problem between the grocery store workers (particularly low back pain and carpal tunnel syndrome among cashiers). Many technical documents and international recommendations are present to prevent these kinds of disorders. Psychosocial risk factors and risk of workplace violence should deserve further investigation.Aim: This work provides an overview of the spectrum of possible occupational risk factors in the retail grocery store/supermarket workplace.Method: Literature on this theme, obtained consulting PubMed database and Google Scholar, was checked. We also explore results from the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA).Results: Contacts with objects, use of dangerous equipment (cutter, food slicer) and falls to the same level (slips, trips and falls) are the mainly described workplace hazards. Exposure to chemical (flour dust, components of detergents or disinfectants, volatile organic compounds and contact with nickel) and physical agents (cold exposure, nonionizing radiation and whole body vibration) are reported by many authors. Relations between biomechanical and ergonomic risk factors and musculoskeletal disorders represent the main subjects of study. Few studies are found about biological agents (particularly among butchers). Data regarding psychosocial risks factors in this setting are still limited
Communication, control and driving assistance to a platoon of vehicles in heavy traffic and scarce visibility.
No full textA decentralized communication and control system is presented for driving assistance and automation along designated highway segments. This paper is based on a hybrid dynamical model describing vehicular motion, and the structure of a safe controller is presented. A ranging and communication system provides information for a vehicle and its nearest neighbors. The system is capable of handling sudden changes of regime, overtakes, reentries, as well as a number of maneuvers dictated by safety requirements under partially unpredicted events. A user-friendly interface, based on a palmtop computer, is developed to assist drivers visually and acousticall
Comparison of ML Solutions for HRIR Individualization Design in Binaural Audio
No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
SDR SAR Target: Corner Reflector and Communication
No full textThis paper presents a novel target, based on software-defined radio (SDR) technology, that allows the support of remote sensing processes and enables a transparent communication link in synthetic aperture radar (SAR) systems. Nowadays the integration of communication services in technologies that are not developed for this purpose can be an interesting solution for the increasing communication demand. The novel target acts in two different ways for SAR systems: as software-defined corner reflector (SDCR) for localization and calibration support, but also as SAR target to integrate a transparent communication link for target identification and tracking
