Electromagnetic and ultrasonic investigations on a Roman marble slab
2011
The archaeological museum of Rome asked our group about the physical consistency of a marble slab (second to third century AD) that recently fell during its travel as part of an exhibition. We decided to use different methodologies to investigate the slab: namely a pacometer (Protovale Elcometer) to individuate the internal coupling pins, and ground-penetrating radar (GPR) (2000 MHz) and ultrasonic (55 kHz) tomographic high-density surveys to investigate the internal extension of all the visible fractures and to search for the hidden ones. For the ultrasonic data, tests were carried out to optimize the inversion parameters, in particular the cell dimensions. Surely, the choice of cell size …
Mobila sirdsdarbības novērošanas ierīce
2015
Pēc slimību profilakses un kontroles centra datiem Latvijā galvenais nāves iemesls joprojām ir sirds un asinsvadu slimības. Viens no galvenajiem sirds un asinsvadu slimību noteicošajiem testiem ir elektrokardiogrammas veikšana ar elektrokardiogrāfa palīdzību. Šo testu var veikt trīs veidos – stacionāri, slodzes un ilglaicīgi. Stacionārais tests ir visvairāk pielietotais, bet ilgst mazāk par minūti. Slodzes testu veic, ja pacientam ir sūdzības par sirdsdarbību nodarbojoties ar fiziskām aktivitātēm. Ilglaicīgo testu veic, lai novērotu sirdsdarbību ilgākā laika periodā, piemēram, 24 stundas. Izmantojot Holter sistēmu pacientam ir neērti, jo pēc testa šī ierīce ir jāatgriež ārsta kabinetā, kur …
Monitoringa sistēmas pilnveidošana
2017
Bakalaura darba “Monitoringa sistēmas pilnveidošana” mērķis bija pilnveidot jau esošu monitoringa sistēmu uzņēmumā “X”. Monitoringa sistēmu nepieciešams pilnveidot, lai tā pilnīgāk un precīzāk veiktu infrastruktūras resursu monitoringu, kā arī precīzi ziņotu par problēmām, papildus nepieciešams izveidot vizualizācijas, kas vizualizētu infrastruktūras uzbūvi. Darba gaitā tika veiktas darbības, kas uzlaboja Zabbix servera veiktspēju, tika izveidoti nelieli skripti, kas ļauj dažādus procesus nedaudz automatizēt, izveidotas vizualizācijas, kas uzskatāmi attēlo notikumus uzņēmuma būtiskākajos infrastruktūras resursos, kā arī novērstas citas nepilnīb…
3 RTPS kritisko funkciju monitoringa nodrošināšana ar Zabbix rīkiem
2017
Kvalifikācijas darba mērķis ir ātra problēmu identificēšana sistēmās, ko iespējams panākt izveidojot grafikus un paziņojumus, kas ļaus administratoram un lietotājiem pārraudzīt esošos procesus centralizēti. Darbs tiks izstrādāts izmantojot Zabbix 3.0 pārvaldības sistēmu, lietojot Orabbix, kas ļaus monitorēt sistēmas procesus. Orabbix tiks ievietoti attiecīgi pieprasījumi, dati tiks iegūti no datubāzēm, kas tiks nosūtīti uz Zabbix, lai tiktu izveidoti grafiki vai saņemti atbilstoši paziņojumi. Ieviesta ērtāka grafiskā vide Grafana, kas dod iespēju aplūkot vairākus grafikus uz viena ekrāna un atspoguļos tos saprotamāk. Darba rezultātā tika izveidots divdesmit viens pieprasījums, no kuriem dar…
A Decision support system for sustainable operations management in small power plants
2014
The importance of environmentally-friendly electricity production is recognized as one of the most important challenges of our future, covering a broad context of research topics and promoting future scenarios based on renewable energies and new technologies. In the short term, however, energy generation will still be largely relying on power plants fired with fossil fuels whose emissions of pollutants are regulated by the industrial emissions directive in the EU legislation. Such directive does not apply to small and medium combustion plants, which until now, have only been subject to national regulations. As part of its air quality package from December 2013, the EU Commission has propose…
Building energy demand assessment through heating degree days: the importance of a climatic dataset
2019
Abstract The weather is one of the main factors to consider when designing a building because it represents the most important boundary condition to affect the dynamic behaviour of the building. In the literature, many studies use the degree day to predict building energy demand. However, linking the results obtained from a generic building simulation tool with defined degree days, will not give reliable energy evaluation. The goal of this study is to demonstrate that the assessment of building energy demand through the use of the degree day is correct only if the determination of the climate index is a function of the same weather data. The relationship between Heating Degree-Day and heati…
Building energy performance forecasting: A multiple linear regression approach
2019
Abstract Different ways to evaluate the building energy balance can be found in literature, including comprehensive techniques, statistical and machine-learning methods and hybrid approaches. The identification of the most suitable approach is important to accelerate the preliminary energy assessment. In the first category, several numerical methods have been developed and implemented in specialised software using different mathematical languages. However, these tools require an expert user and a model calibration. The authors, in order to overcome these limitations, have developed an alternative, reliable linear regression model to determine building energy needs. Starting from a detailed …
Implementation of a knowledge-based methodology in a decision support system for the design of suitable wastewater treatment process flow diagrams.
2011
In light of rapid global change, the demand for wastewater treatment is increasing rapidly and will continue to do so in the near future. Wastewater management is a complex puzzle for which the proper pieces must be combined to achieve the desired solution, requiring the simultaneous consideration of technical, economic, social and environmental issues. In this context, a knowledge-based methodology (KBM) for the conceptual design of wastewater treatment plant (WWTP) process flow diagrams (PFDs) and its application for two scenarios is presented in this paper. The core of the KBM is composed of two knowledge bases (KBs). The first, a specification knowledge base (S-KB), summarizes the main …
An integrated information system for the acquisition, management and sharing of environmental data aimed to decision making
2012
This paper reports the first results of the Project SESAMO - SistEma informativo integrato per l’acquisizione, geStione e condivisione di dati AMbientali per il supportO alle decisioni (Integrated Information System for the acquisition, management and sharing of environmental data aimed to decision making). The main aim of the project is to design and develop an integrated environmental information platform able to provide monitoring services for decision support, integrating data from different environmental monitoring systems (including WSN). This ICT platform, based on a service-oriented architecture (SOA), will be developed to coordinate a wide variety of data acquisition systems, based…
GPS Monitoring of the Scopello (Sicily, Italy) DGSD Phenomenon: Relationships Between Surficial and Deep-Seated Morphodynamics
2015
The Scopello area, which is located along the north-western Tyrrhenian coastal sector of the Sicilian chain (Italy), is widely affected by Deep-seated Gravitational Slope Deformation (DGSD) phenomena, which are mainly the result of a geomorphologic setting marked by the outcropping of an overthrust plan, limiting a brittle fractured carbonate slab, laid onto a ductile marly-clayey substratum. Due to the very advanced stage of the deformation phenomena, a coupled morphodynamic style has established between shallow landslides and DGSD phenomena, affecting the exhumed ductile substratum and the overlaying rigid dismantled slab, respectively. A GPS network was realized for monitoring the Scopel…
