Diez años de smartphones. Un análisis semiótico-comunicacional del impacto social de la telefonía móvil
2018
El teléfono móvil con conexión a Internet (o smartphone) es la tecnología que más rápidamente se ha difundido en la sociedad actual y ha producido hábitos decisivos en los estilos de vida de la ciudadanía. Esta investigación examina desde una perspectiva semiótica-comunicacional la relación de diferentes sectores de la sociedad de hoy con estos dispositivos. Se sirve del universo narrativo del programa “Conectados” de la serie Salvados, programa dedicado precisamente al uso social de esta tecnología justo a los diez años de la aparición del primer smartphone. A través del análisis de los contenidos volcados por los diversos actores que intervienen –adolescentes, adultos, familias, escuela y…
Field testing of repurposed electric vehicle batteries for price-driven grid balancing
2019
Abstract As electric cars become more widespread, the disposal and recycling of used batteries will become an important challenge. Typically, vehicle batteries are replaced if their capacity drops to 70–80% of initial capacity. However, they may still be useful for stationary applications. In this paper, results from a field test of a molten salt high-temperature electric vehicle battery repurposed as stationary storage for grid balancing are presented. In a previous study, we have shown that a mixed integer linear programming control strategy driven by a spot-market price for electricity is best suited for an implementation on hardware with limited computational resources. A 14-day experim…
Helical Shift Mechanics of Rubber V-Belt Variators
2011
A very common configuration of V-belt variators for motorcycles considers the correction of the belt tensioning depending on the resistant torque by means of suitable helical-shaped tracks allowing the driven half-pulleys to close/open. The theoretical model for belt-pulley coupling is rather complex for this configuration, where one half-pulley may run in advance and the other one behind with respect to the belt, and requires the repeated numerical solution of a strongly nonlinear differential system by a sort of shooting technique, until all the operating conditions are fulfilled (angular contact extent, torque, and axial force). After solving the full equations, the present study develop…
Informācijas Tehnoloģiju iespēju izmantošana būvniecības projektu tāmēšanas pārvaldībā
2016
Būvniecības tāmju izstrādē visplašāk izmantotā lietojumprogramma ir MS Excel lietotne, kas nodrošina tāmēšanai nepieciešamo izklājlapu tabulāro formu un aprēķinu formulu veidošanu, kā arī datu kopēšanas un citu tekstuālu un skaitlisku datu apstrādes funkcionalitāti. Lai arī MS Excel programmatūra ir vispār atzīta tāmētāja darba vietas platforma, izklājlapu programmatūra ir limitēta un nesniedz visu tāmēšanas darbu pārvaldībai nepieciešamo atbalstu, ko ir iespējams nodrošināt ar informācijas tehnoloģiju risinājumiem. Lai identificētu konkrētas tāmēšanas procesa efektivizēšanas iespējas, darba ietvaros veikta būvniecības tāmju izstrādē ietverto procesu apskats un analīze, veikta izpēte par ti…
Economic Robustness Analysis of Adaptive Chart Schemes for Monitoring the Total Nonconformities Number in Inspection Units
2015
In recent years, a variety of enhanced schemes for the c chart have been developed aimed at the effectiveness improving of the related statistical process control (SPC) procedures. However, the performance of such chart schemes can be very sensitive to values assumed for some operating and cost parameters, in particular to the considered process shift magnitude arising from out-of-control conditions. In such a circumstance, the effectiveness of such chart schemes can be subjected to substantial reductions when they are implemented in operative contexts given that, in practice, such value is unknown and it can be very difficult to accurately estimate. For this reason, in the present paper i…
Real-time data processing in the ALICE High Level Trigger at the LHC
2019
At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/$s$. The ALICE High Level Trigger (HLT) system pioneered the use of FPGA- and GPU-based algorithms to reconstruct charged-particle trajectories and reduce the data size in real time. The results of the reconstruction of the collision events, available online, are used for high level data quality and detector-performance monitoring and real-tim…
Il governo del capitale intellettuale attraverso il raccordo tra modelli contabili e di System Dynamics. Una prospettiva di programmazione e controll…
2004
Il presente scritto tenta di far luce sul tema del capitale intellettuale in una prospettiva economico-aziendale, focalizzando in particolare il concetto di governo della conoscenza aziendale. La tesi sostenuta dagli autori è che i processi inerziali di sviluppo e declino della conoscenza non devono essere astrattamente ignorati, relegando l’area Organizzazione e Sistemi al rango di centro di spesa discrezionale. Questa semplicistica prospettiva di analisi può indurre il management all’adozione di politiche miopi, che portino cioè a rinviare investimenti necessari in sviluppo della conoscenza, con l’unico obiettivo di non deprimere i risultati reddituali di breve andare. A tal riguardo, si …
A hardware skin-segmentation IP for vision based smart ADAS through an FPGA prototyping
2017
International audience; In this paper we presents a platform based design approach for fast HW/SW embedded smart Advanced Driver Assistant System (ADAS) design and prototyping. Then, we share our experience in designing and prototyping a HW/SW vision based smart embedded system as an ADAS that helps to increase the safety of car's drivers. We present a physical prototype of the vision ADAS based on a Zynq FPGA. The system detects the fatigue state of the driver by monitoring the eyes closure and generates a real-time alert. A new HW/SW codesign skin segmentation step to locate the eyes/face is proposed. Our presented new approach migrates the skin segmentation step from processing system (S…
Effects of statins, fibrates, rosuvastatin, and ezetimibe beyond cholesterol: the modulation of LDL size and subclasses in high-risk patients.
2007
Increasing evidence suggests that the quality-rather than just the quantity-of low-density lipoproteins (LDLs) exerts a great influence on cardiovascular risk. LDLs comprise multiple subclasses with discrete size and density, and different physicochemical composition, metabolic behaviors, and atherogenicity. Individuals generally cluster into 2 broad subgroups. Most have a predominance of large LDLs, and some have a higher proportion of small particles. Small, dense LDLs are good predictors of cardiovascular events and progression of coronary artery disease. Their predominance has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Tre…
"Młodzi na progu" - propozycja kerygmatyczno-mistagogicznego przygotowania do sakramentu bierzmowania
2017
Katecheza inicjacyjna obejmuje różne formy nauczania i wychowania prowadzące do przygotowania do przyjęcia sakramentów wtajemniczenia chrześcijańskiego. Ten rodzaj katechezy jest realizowany w ramach programu Młodzi na progu jako materiał do pracy z młodymi ludźmi przygotowującymi się do sakramentu bierzmowania w swoich parafiach. Jest to swoisty sposób by odpowiedzieć na pytanie: Jak pomóc bierzmowanym pozostać w Kościele i być Kościołem? Zasadniczym celem programu jest zachęcenie uczestników spotkań formacyjnych do pracy nad własnym rozwojem, zarówno intelektualnym, jak i duchowym. W tym programie najbardziej dominującymi aspektami są aspekty egzystencjalne, kerygmatyczne i mistagogiczne.…
