We employ a novel method to analyze Euclidean correlation functions entering the calculation of hadron energies in lattice QCD. The is based on sampling all possible solutions allowed by spectral decomposition correlators. demonstrate applicability studying nucleon excited states positive- and negative-parity channels over pion mass range about 400 150 MeV. results are compared standard variational approach routinely used study within main advantage our new its ability unambiguously...
This paper builds on and extends the R&D work techno-economic analysis of cogeneration desalinated water electricity by Cyprus Institute (2012) (Solar Thermal Cogeneration Electricity Water: Research Development study for a Concentrated Solar Power—Desalinization Sea Water (CSP–DSW) C.N. Papanicolas & G. Tzamtzis editors. The Institute, Nicosia, Cyprus, 2012. ISBN: 978-9963-2858-0-8). Three different Power (CSP) plant configuration options operating in are examined this paper: an...
The Cyprus Institute's Pentakomo Field Facility (PFF) is a major infrastructure for research, development and testing of technologies relating to concentrated solar power (CSP) seawater desalination. It located at the south coast near sea its environmental conditions are fully monitored. provides test facility specializing in CSP systems suitable island coastal environments with particular emphasis on small units (<25 MWth) endowed substantial storage, use isolation or distributed grids....
Concentrating solar thermal power coupled with energy storage is considered as one of the leading technologies to address decarbonization sector. The use molten salt (60–40% b.w. NaNO3-KNO3) heat transfer fluid and medium current commercial practice, alternative mixtures being under evaluation for next-generation higher-temperature systems. main drawback salts their high freezing temperature; active means are required preheating of- prevent from in- lines. In this article we present...
This Colloquium addresses the issue of shape hadrons and, in particular, that proton. The concept microcosm is critically examined. Special attention devoted to properly define meaning for bound-state systems near massless quarks. ideas lead expectation nonsphericity hadrons, calculations predict it, and experimental information obtained from recent high-precision measurements are Particular emphasis given study electromagnetic transition between nucleon its first excited state,...
This paper examines the thermal comfort conditions during summer and winter in an existing office building urban context. It investigates correlates results obtained from a questionnaire survey, conducted winter, with two models – for mechanically ventilated spaces non-mechanically ones - order to determine most appropriate one energy performance evaluation of buildings coastal Mediterranean region.

Decarbonisation of national economies to mitigate climate change requires transformation the entire energy system. Investments in renewable technologies electricity supply system are increasing, but substantial effort is called for other sectors, such as transport. While European Union member states have submitted their integrated National Energy and Climate Plans, this paper focuses on partial electrification transport sector a measure reduce carbon dioxide emissions isolated grid Cyprus...
The paper presents the architectural, engineering and energy design of a laboratory building located in Cyprus. is designed to meet near-zero consumption criteria using advanced conservation measures, smart management solar thermal photovoltaic systems cover remaining load. techniques used result reduced by almost 70% compared with conventional building, while 27% heating-, cooling- lighting load covered photovoltaics.

We explore a novel method for tomographic image reconstruction in the field of Single Photon Emission Computerized Tomography (SPECT) imaging. Deep Learning methodologies and more specifically deep convolutional neural networks (CNN) are employed new method, which is referred to as "CNN Reconstruction - CNNR". Projection data were obtained from software phantoms used evaluate efficacy method. The resulting images compared those produced by "Maximum Likelihood Expectation Maximization" (MLEM)...

This hybridization would be undertaken installation PV arrays under mirrors, so that is able either reflect...
Solar concentration systems are usually deployed in large open spaces for electricity generation; they rarely used to address the pressing energy needs of built environment sector. Fresnel technology offers interesting and challenging CSP pathways suitable environment, due its relatively light weight (<30 kg.m−2) low windage. The Cyprus Institute (CyI) Consorzio ARCA cooperating such a research program; we report here construction integration 71kW system into HVAC (Heating, Ventilation, Air...
In Europe, 27% of final energy use occurs in residential buildings and another 14% tertiary buildings, making the "building sector" largest end-use consumer with over 40% total. The consumed within European averages to 70-230 kWh/m2 per year. Achieving a nearly zero (NZE) target is both necessary crucial.
