Electronic Energy Meter Based on a Tunnel Magnetoresistive Effect (TMR) Current Sensor
2017
In the present work, the design and microfabrication of a tunneling magnetoresistance (TMR) electrical current sensor is presented. After its physical and electrical characterization, a wattmeter is developed to determine the active power delivered to a load from the AC 50/60 Hz mains line. Experimental results are shown up to 1000 W of power load. A relative uncertainty of less than 1.5% with resistive load and less than 1% with capacitive load was obtained. The described application is an example of how TMR sensing technology can play a relevant role in the management and control of electrical energy.

Two-particle transverse momentum correlations in pp and p-Pb collisions at energies available at the CERN Large Hadron Collider
2023
Two-particle transverse momentum differential correlators, recently measured in Pb--Pb collisions at energies available at the CERN Large Hadron Collider (LHC), provide an additional tool to gain insights into particle production mechanisms and infer transport properties, such as the ratio of shear viscosity to entropy density, of the medium created in Pb-Pb collisions. The longitudinal long-range correlations and the large azimuthal anisotropy measured at low transverse momenta in small collision systems, namely pp and p-Pb, at LHC energies resemble manifestations of collective behaviour. This suggests that locally equilibrated matter may be produced in these small collision systems, simil…
Electrooxidation of diesel fuel in alkaline electrolyte
2016
In recent decades the demand of energy has increased significantly.Providing more and more energy is an essential task of today’s energetic industry. In the last few years, addition to traditional methods of energy production, alternative energy sources have been developing fast.One of these sources is fuel cell, mainly due to their high efficiency. Generally fuel cells are powered by hydrogen. However, problems with the storage of hydrogen are the reason for the search of new fuels for fuel cells. Moreover, fuel cells can provide an additional/emergency electricity source in energy systems using combustion engines. So, it is important using the main fuel for powering the fuel cell. One of …
Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.
2014
Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, hi…
Aprendre a la ciutat a través de la deriva
2014
La deriva ha estat la inspiració i el camí per a profunditzar en l¿apre- nentatge que suposa caminar la ciutat. Els passos que anàvem donant ens han portat a replantejar-nos diferents aspectes educatius que transcendeixen les nostres pretensions inicials. Partim dels estudis crítics i postcrítics del currí- culum, i així, a poc a poc, hem anat aproximant-nos a la recerca, la pedagogia o la didàctica. Tota aquesta experiència gira al voltant del taller «Educar la mirada/Documentar la ciutat» amb el qual hem caminat per diferents indrets de la nostra ciutat, al costat del professorat i l¿alumnat de diferents estudis de grau de les universitats valencianes. Volem pensar la ciutat a través del …
Postpandemic Urban Habitat in the Age of Contamination
2020
The challenge for post-pandemic urban habitats will be to recover their natural polycentrism, the diversity of their neighborhoods which, ceasing to be fragile suburbs, return to being places of lives and not just of homes, bridging the educational, working, cultural, digital divides, acquiring micro-places of public health and self-sufficient energy communities. I imagine cities of a renewed urban proxemic made up of "augmented urban communities" (according to the principles I described earlier) that reduce their frantic centripetal mobility and that facilitate a more measured mobility guaranteeing the answer to many needs within 15 minutes from home (the “15-minute city”, as already launc…
Wybrane przykłady realizacji koncepcji miasta-ogrodu oraz możliwości implementacji ich elementów we współczesnej tkance miejskiej
2020
Praca stanowi przekrój myśli urbanistycznej, jaką jest koncepcja miasta- ogrodu. Celem pracy jest przedstawienie sposobu kształtowania współczesnej tkanki miejskiej w odniesieniu do założeń garden city na przykładzie miasta Opole. Obecne tendencje w planowaniu przestrzennym miast zdają się nie uwzględniać szeroko rozumianego krajobrazu jako waloru. Niniejsza praca powstała z myślą o przybliżeniu założeń opartych na zasadzie połączenia środowiska zbudowanego z naturalnym, pokazując, że mogą być one funkcjonalnymi i kompletnymi tkankami miejskimi
Social Media as Platform for Stimulating Urban Changes
2016
Images have always been an important part of city planning – current images of place, images with planned improvements, maps and sketches. Some time ago all that was a private property of stakeholders like planner and client. But nowadays this confidentiality rather much has vanished – no copyrights or competition is noteworthy. Plans do not have their privacy anymore. They are exposed even before they got implemented. This article will display why city planners share the images of their ideas, of their dreams in public (mostly in blogs and social networks) – why it is important for them and what kind of feedback they are waiting for. This article is based on case study where 12 respondents…
