Pique-niquer in Paris
2015
Una antica tradizione rinnova il rapporto tra Parigi e i suoi abitanti: l’uso sociale e pubblico di prati, giardini, scalinate, sponde dei canali e lungofiume per consumare, con estrema nonchalance, il rito del picnic. Pique-niquer è un verbo francese che abbina piquer (prendere, rubacchiare, spilluzzicare) con nique (piccola cosa di poco valore). La città gli tributa generosamente i suoi spazi pubblici dove si riversano coppie, gruppi, famiglie, attrezzati di tutto punto per godere di un pranzo o soltanto di uno spuntino all’aperto, immersi tra i panorami urbani più suggestivi. An old tradition renews the relationship existing between Paris and her inhabitants: the social and public use…
Barcelona’s Urban Markets; I mercati urbani di Barcellona
2016
I mercati non sono solo potenti dinamizzatori dell’economia urbana come luoghi del commercio di prossimità, dell’occupazione e dell’imprenditorialità, ma svolgono un importante ruolo di aggregazione sociale e di promozione culturale che concorre ai processi di rigenerazione urbana. Ben consapevole di tali funzioni, l’Ajuntament de Barcelona ha istituito nel 1991 un organismo autonomo per la gestione diretta e l’amministrazione dei mercati di Barcellona, l’IMMB (Institut Municipal de Mercats de Barcelona), che provvede anche alla modernizzazione dei mercati attraverso il miglioramento delle infrastrutture e dei servizi alla persona, l’adeguamento dell’offerta merceologica in base alle nuove …
Cascaded Multilevel Inverter-Based Asymmetric Static Synchronous Compensator of Reactive Power
2022
The topology of the static synchronous compensator of reactive power for a low-voltage three-phase utility grid capable of asymmetric reactive power compensation in grid phases has been proposed and analysed. It is implemented using separate, independent cascaded H-bridge multilevel inverters for each phase. Every inverter includes two H-bridge cascades. The first cascade operating at grid frequency is implemented using thyristors, and the second one—operating at high frequency is based on the high-speed MOSFET transistors. The investigation shows that the proposed compensator is able to compensate the reactive power in a low-voltage three-phase grid when phases are loaded by highly asymmet…
Conceptualisation et évaluation d'une typologie de lotissement vertical pour un aménagement urbain durable
2020
The current urban development process is the result of a paradoxical situation. On the one end, families prefer individual housing, which finds the favourable conditions to its spreading in the more or less distant from towns outskirts, while wishing to benefit from services (proximity to amenities, public transport offers, etc…) which are rather the corelate of dense urban centralization. On the other hand, in order to fight against environmental, social and economic costs of urban sprawl, and also aim towards a more sustainable city, the urban renovation and compact city projects lead to some density levels that only collective housing enables to reach. So, the equation - control of the u…
Artura Šniclera daiļrade mūsdienu kontekstā: Šniclera darbu recepcija Latvijā pēc 1991. gada
2018
Bakalaura darbs apskata Artura Šniclera daiļradi mūsdienu kontekstā, īpaši akcentējot Šniclera darbu recepciju Latvijā pēc 1991. Bakalaura darba mērķis ir analizēt Artura Šniclera darbu recepciju Latvijā laika periodā no 1991. gada līdz 2018. gadam. Tā kā šajā laika periodā divas reizes ir tulkots un izdots darbs ar nosaukumu „Sapņa novele” un četras reizes uzvesta luga „Riņķa dancis”, ir pamats uzskatīt, ka šie darbie tiek interpretēti ļoti dažādi. Analizējot teātra kritiķu recenzijas, tiek secināts, ka režisori Latvijā interpretē Šniclera darbu, izmantojot dažādus teātra paņēmienus, tādējādi atklājot skatītājiem autora darbu ikreiz no cita skatpunkta. Tāpat tiek secināts, ka Šniclera darb…
Energy and environmental assessment of residual bio-wastes management strategies
2021
Abstract This paper assesses the potential energy and environmental impacts of an anaerobic digester coupled with a combined heat and power plant powered with bio-wastes from the agri-food sector. The analysis is carried out through the Life Cycle Assessment methodology following a “cradle-to-grave” approach and is based mostly on primary data. The anaerobic digester - combined heat and power plant is analysed considering a twofold perspective: one more energy – oriented where the main function of the system is to generate renewable electricity and a waste – oriented one in which the main function is treating bio-wastes. In addition, the environmental indirect effects related to potential c…
Manure as a potential source of renewable energy: The behaviour and characterisation of biofuels generated from three animal manure types when subjec…
2020
Regions with high livestock density lack sufficient land on which to apply manure without exceeding the legal limits set by the European Union Directives. The lack of manure processing alternatives aggravates the situation, especially in the case of islands. Consequently, manure becomes a liability rather than an asset. Results indicate that pyrolysis is an option for manure processing. However, a significant limitation is the moisture content of the starting material, that could compromise the process efficiency. Yields of biogas, bio-oil and biochar, all of which have a potential use as biofuels, are particular to animal type and manure handling system. The conversion of manure to biofuel…
Numerical and experimental investigation of a cross-flow water turbine
2016
ABSTRACTA numerical and experimental study was carried out for validation of a previously proposed design criterion for a cross-flow turbine and a new semi-empirical formula linking inlet velocity to inlet pressure. An experimental test stand was designed to conduct a series of experiments and to measure the efficiency of the turbine designed based on the proposed criterion. The experimental efficiency was compared to that from numerical simulations performed using a RANS model with a shear stress transport (SST) turbulence closure. The proposed semi-empirical velocity formula was also validated against the numerical solutions for cross-flow turbines with different geometries and boundary c…
Technological and legislative status point of stationary energy storages in the EU
2019
Abstract European renewable generation has been supported through several policy instruments in the last decades, and this has caused a significant growth of the renewable energy sector, spurred by the ambitious climate and energy policy targets. Despite this impetuous growth, the electricity infrastructure is not yet ready to accept increasing shares of variable renewable energy sources (RES) generation, and this is causing grid balance challenges, due to the inherently variable nature of the PV and wind energy. In order to overcome this issue, allowing higher shares of renewable generation in the energy sector, energy storage (ES) systems are becoming increasingly competitive in the globa…
Optimizing the generation system in a microgrid with power, thermal energy and mobility demands
2021
Microgrids are widely known to be the future of generation and distribution systems. This paper presents a method to optimize the size of the main components in a microgrid to supply the demands for electricity, heating and hydrogen for mobility through an Energy Hub model. The electricity production from a wind turbine, a CHP and a fuel cell satisfies the local electricity demand. The green hydrogen produced in the hub from renewable power in off-peak hours is used to feed the fuel cell or to meet the mobility demand. The heating power from CHP and fuel cell is used to feed the local district heating network.
