Basis pursuit (BP) with $ell_{1}$-norm criterion received much attention in the past. One of its obvious applications is the discrete-time sparse signal acquisition. In this work, two alternative forms of the BP optimization are presented. Both are intended to perform the same task as the BP but are expressed as linear programming (LP) frameworks. The performance of the LP expressions, which are equivalent to the BP, is observed and then compared to that given by the typical BP. It is found that the error performance of the equivalent BP methods in terms of LP is the same as that of the BP algorithm. One of the BP-equivalent LP problems takes the same computational time as the BP, while another lasts longer in computation. In the same manner, the first BP-equivalent LP problem consumes nearly the same amount of required memory as the BP, whereas another occupies significantly more memory space during the computation.

Breath monitoring of sedated and under-treatment patients is a key clinical procedure in hospitals. Non-invasive de-vices are preferable to perform a comfortable screening, and they assume greater importance in case the patients are newborns. Ultra High Frequency (UHF) Radio Frequency IDentification (RFID) breath sensors are passive devices that can enable low-invasive and wireless monitoring of respiration. By embedding temperature sensors within their Integrated Circuits (ICs), these devices are compact and can record temperature signals that can be correlated with typical flow-based signals. This paper aims at assessing the feasibility of involving RFID breath sensors for the monitoring of newborns breathing temperature in a real hospital ward. A pediatric disposable facemask was sensorized with a T-match dipole antenna. Following a preliminary evaluation of its electromagnetic performance and safety, in-hospital breath monitoring was performed on a newborn undergoing mild hypothermia treatment. Compared to traditional flow meter measurements, RFID results are promising and the ease-of-use and the wireless transmission of the data permit the monitoring of patients without interfering with the undergoing treatments.

Decentralized trigeneration (solar heating-cooling) for residential and commercial applications is being researched and adapted extensively. The transition from traditional uni-directional grids to bidirectional smart grids has motivated energy engineers to develop novel decentralized architectures that fully exploit distributed generation technologies. Solar heat and light stimulated trigeneration system is modeled, simulated, and analyzed over one year for subtropical climate conditions of Melbourne, Australia. The architecture replaces an electrical compressor of traditional chillers with solar heat stimulated absorption chiller. A residential building is scheduled as per standard living trends of a family of 5 individuals. The goal was to maintain livable thermal conditions (PID controlled: 26°C) and meet essential electronic needs at best. A detailed thermal and electrical performance analysis is documented using parameters such as solar fraction, collector thermal efficiency, fractional non-purchased energy, and others. The architecture was designed to meet all energy loads, thermal and electrical, with minimal auxiliary or grid energy expenditure. The analysis revealed that this unique combination of active and passive solar electro-thermal technologies has the potential to improve the overall performance and save considerable space for residential build environments. The solar photovoltaics produced power in the range 200 kW to 519 kW, active solar evacuated tube collectors produced hot water in the range 60-80°C, and passive solar thermal wall recorded storing heated air up to 70°C in summers and 40°C in winters. Heated water passed through solar heat stimulated absorption chillers to produce chilled air in range 17-19°C. An excess of 1500 watts on some summer days was recorded while no excess was available in peak winters. Solar fraction and fractional non-purchased energy showed slightly better performance than the same systems without a thermal wall.

Monitoring the performance of athletes is crucial for improving exercise quality and planning new training goals. Specifically, boxing sports demand strength and balance, requiring concentration and coordination when training with a speed bag. With a speed bag, the boxer has to strike the bag repeatedly while the bag moves fast and maintains a rhythm of hits. A monitor system for this type of training is challenging because it must be unobtrusive to keep the boxer focused on the exercise. This study introduces a methodology to get the frequency of the speed bag, which is a crucial feature to get insight into the boxer's performance. Our approach takes advantage of UHF Radio Frequency Identification (RFID) technology. RFID tags are small and can easily be embedded in the speed bag without hindering the activity of the boxer. Our methodology uses the phase of the backscattered signal as the tag and bag move together, allowing to extract the oscillation frequency. Performed simulations reflect the bag motion at an indicated frequency of 4 Hz and up to 4 meters of tag-to-reader separation. This preliminary study establishes the system's applicability, which can obtain the oscillation rate without human intervention.

Batteries of plug-in electric vehicles (PEVs) can be used in vehicle-to-grid (V2G) systems for controlled bidirectional power flow between the vehicles and the power grid. Some benefits of V2G include the use of PEVs to provide ancillary services to the grid. However, there are concerns about PEV use for these services, particularly about the degradation of vehicle batteries due to frequent charging and discharging. In this study, a model is used to calculate the total cost of battery degradation for a significant number of vehicles as a result of V2G. Battery degradation is considered to be caused by cycling aging because this type of aging occurs during the V2G process. Simulation is conducted to determine how the battery degradation cost changes based on competing objectives. This study demonstrates the importance of considering PEV battery health during V2G operation and shows how battery degradation can be affected by the different objectives of the aggregator and PEV owners.

This paper introduces a bagging ensemble classifier, built from support vector machines (SVM), for predicting lightning flashovers on overhead distribution lines (OHL). Support vectors from the underlying SVM give rise to the so-called curve of limiting parameters (CLP), which features prominently in the statistical method of insulation coordination. Proposed machine learning-based approach enables a straightforward derivation of the line's CLP-from simulations or actual measurements data gathered by the lightning location systems-for its subsequent use in insulation coordination studies. It also facilitates computing the risk of insulation flashover. Both these aspects fully endorse statistical approach to the insulation coordination and flashover performance analysis of OHLs.

Electric Vehicles (EVs), as well as the number of applications for their management, are rapidly increasing due to the fact that Internet of Vehicles (IoV) becomes more informative and industrialized. According to the literature, IoV requires decentralization towards the energy Demand Response (DR) management, with secure energy trading, efficient charging scheduling, and incentives for making the drivers to participate. Blockchain and Distributed Ledger Technologies (DLTs) can be used to enable a foundational environment to support DR management. However, and to the best of our knowledge, none of the existing research works discussed in the literature adopts a holistic approach to address them. As such there is a demand for exploring a unified blockchain-based framework for distributed DR management. Therefore, the aim of this work is focused on the blockchain adoption in IoV-assisted smart cities. More specifically, we propose a blockchain based approach, to be used for building a secure and user-centric DR management framework. Our proposition aims to address the DRP in IoV through charging scheduling based on the generation of EV driving profiles, and optimal Vehicle-to-Vehicle/Grid (V2V | V2G) energy trading.

Skin prick testing (SPT) is a reliable method to diagnose IgE-mediated allergic disease in patients with rhino conjunctivitis, asthma, urticaria, anaphylaxis, atopic eczema and suspected food and drug allergy. Due to the the lack of wheals public available dataset and related diameters and due to expen-sive acquisition system, in this work we investigate the feasibility to have high performance and low cost device for wheals detection and measurements. Having cheap acquisition device, it would be easier to have more acquisition stations per clinic, also speeding up the process of building the dataset. Proposed paper aims to automate the wheals measuring process, by detecting multiple wheals and by isolating them from the rest of the image, which is an essential step for the dataset building. We also proposed a cheap acquisition system made by a consumer type depth camera, Intel Realsense d435, a 3D printed arm support, a touchscreen panel displaying a GUI for the acquisitions, a Raspberry Pi 4 computer. Preliminary results showing promising performance even if they are acquired with a very cheap acquisition station proposed.

The energy and water demand is growing at an increasing rate on a global scale. This trend is especially pronounced in urban areas, which expand rapidly in size and population. At the same time, there is strong evidence to suggest that urban buildings are a major contributor to the resource and emissions footprint of human activity. For this reason, there are a number of initiatives, on a global and national level, to assess and improve the energy efficiency of buildings. This paper presents the development of a fast method for modelling the electricity, water consumption and indoor air temperature of a municipal kindergarten building in Sofia, Bulgaria. The models utilise a hybrid approach to analysing the data and successfully represents its trend. The use of statistical methods results in highly interpretable results, which can be built upon with more sophisticated techniques to achieve increased accuracy.

Urban Digital Transformation opens many opportunities for cities, but there are also risks that the evolution of our cities may be driven by the unforeseen effects of emerging technologies or by the interests of technology corporations, rather than by the ethical values and real needs of society. The active engagement of citizens can be the key for an effective alignment between technological progress and societal progress. However, most citizens are essentially unaware of changes, much less of their more profound future implications. There is also scarcity of contexts where they can engage in informed discussions about the future of their city and the cocreation of new services. In this work, we explore how Future Thinking and Responsible Research and Innovation may provide a methodological background for promoting systematic reflection about possible futures and elicit generic policy guidelines for novel urban digital services. The goal is to help closing the gap between science, policy makers and society, by helping to shape strategic agendas for innovation on Smart Cities. The key contribution is a thorough analysis of the key motivations associated with this type of societal reflection and the proposal of a novel framework for the responsible design of digital services for cities. The proposed framework is conceived to work as a large-scale and open science project, where multiple stakeholders could concurrently add contributions to this reflection framework.

The goal is to help closing the gap between science, policy makers and society, by helping to shape strategic agendas for innovation on Smart Cities. The key contribution is a thorough analysis of the key motivations associated with this type of societal reflection and the proposal of a novel framework for the responsible design of digital services for cities. The proposed framework is conceived to work as a large-scale and open science project, where multiple stakeholders could concurrently add contributions to this reflection framework.","PeriodicalId":295373,"journal":{"name":"2022 7th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127628665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
