Air-to-water heat pumps are attractive as a replacement of inefficient fossil fuel-based heating systems in thermally renovated buildings. If existing radiator not replaced during renovation, high flow temperatures limit the efficiency pump. For such we analysed possibility to reduce grid electricity consumption by combining pump with photovoltaic system, thermal storage (water tank) and an intelligent rule-based control system that enables targeted operation on-site PV electricity. Detailed...
The evidence supporting the presence of individual brain structure correlates externalizing spectrum (EXT) is sparse and mixed. To date, large-sample studies brain-EXT relations have mainly found null to very small effects by focusing exclusively on either EXT-related personality traits (e.g., Hyatt et al., 2022) or disorders/symptoms Mewton 2022). In this preregistered study using IMAGEN data (N = 1,370), we investigated structural EXT factors that comprise both antagonism) psychopathology...
The rise of autonomous weapons technology in recent conflicts demonstrates the increasing militarisation artificial intelligence. rapid development new technologies, such as AI-based targeting systems and systems, poses significant challenges to international community. On one hand, there are potential threats associated with militarised other ethical dilemmas related algorithmic decision-making legal liability. While efforts have been made over past decade establish a regulatory framework...
This paper presents results from the national Austrian project "Highly efficient combinations of solar thermal and heat pump systems (SolPumpEff)". In this different energy are considered through dynamic system simulations in TRNSYS [1]. such can be used on one hand directly to charge buffer storage other as source for evaporator (HP). work systems, which is only (parallel operation HP) using collectors also a HP analysed compared conventional air systems. With combined parallel performance...
Thermal energy storage is a key technology that can support the transformation of our system to renewable sources. Compared sensible systems commonly used in heating, ventilation and air conditioning, phase change material (PCM) based offer significantly higher capacities due latent solid-liquid change. In this work, we analyzed PCM using commercially available modules with special, non-spherical shape. For future performance analysis cooling application by means simulations, simulation...
Engineering principles and new applications for the nascent field of synthetic biology are just beginning to be explored. Here, we report engineering four novel biological systems: (1) a Bacterial Dynamo, generating electricity using modified magnetotactic bacteria on microfabricated device; (2) Cancer StickyBots, targeting destroying tumour cells engineered Escherichia coli cells; (3) Human Encryption, an information encoding, storage, retrieval scheme potential security medical diagnostic...
Due to recent changing climate conditions and glazing of building facades, a rapid increase in the requirement cooling systems can be observed. Still main energy source for are fossil fuels. In this article we report on fully integrated approach running heat pump actively test room by electric energy, generated facade photovoltaic modules, “COOLSKIN” system. Photovoltaic facades emission free operation phase, efficiently utilize otherwise unused surfaces, portray favorable method terms...
Heat pumps are increasingly used for thermal energy supply in multi-family buildings. However, especially case of central domestic hot water preparation systems, high temperatures at least 60 °C required because the risk legionella growth. This leads to lower efficiency and, due operational limits air-source heat pumps, often also increased operation electrical backup heater. In this study, we analyse effect a desuperheater integrated pump, enabling be provided comparatively low condensation...
