The character and origin of the manuscripts in the present edition
1995
In the following I try to provide the reader with all the details needed to insert the Godel essays appearing here in the broader context of the rest of his unpublished work, as well as everything about my personal work on them. I start with a short description of what can be found in the Godel Nachlass in Princeton, USA, by referring to the catalogue prepared by John Dawson. Then I attempt to justify the particular selection I made of the manuscripts which I finally decided to study, reconstruct and publish. Such an explanation seems to be advisable given the great amount of Godel’s material unpublished but still extant. Also, I describe some of the historical details relevant to understan…
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…
A new ATLAS muon CSC readout system with system on chip technology on ATCA platform
2015
The ATLAS muon Cathode Strip Chamber (CSC) backend readout system has been upgraded during the LHC 2013-2015 shutdown to be able to handle the higher Level-1 trigger rate of 100 kHz and the higher occupancy at Run 2 luminosity. The readout design is based on the Reconfigurable Cluster Element (RCE) concept for high bandwidth generic DAQ implemented on the Advanced Telecommunication Computing Architecture (ATCA) platform. The RCE design is based on the new System on Chip XILINX ZYNQ series with a processor-centric architecture with ARM processor embedded in FPGA fabric and high speed I/O resources together with auxiliary memories to form a versatile DAQ building block that can host applicati…
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…
Performances of the Fault Decoupling Device when unbalanced and multiple faults occur on distribution systems.
2005
Nowadays industrial processes are largely based on electronic devices such as programmable logic controllers and adjustable speed drives. Consequently, industrial equipments became less tolerant towards power supply disturbances. Voltage dips due to faults are surely among the worst disturbances for industrial equipments. A paper machine can be affected by disturbances of only 10% voltage drop lasting for 100 ms. A voltage dip of 75% (of the nominal voltage) with a duration shorter than 100 ms results in material loss in the range of thousands of US Dollars for semiconductors industry [1].
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…
Computer-assisted preparation in conference interpreting
2017
Preparation has been proposed in the literature as one of the most important phases of an interpreting assignment, especially if the subject is highly specialised. Preparing an assignment in advance aims at bridging the linguistic and extra-linguistic gap between conference participants and interpreters and at reducing the cognitive load during interpretation. For these reasons it is considered crucial in ensuring higher interpreting quality. Yet, preparation is generally time-consuming and interpreters may often experience the feeling of not knowing exactly how to perform this task efficiently. Information technology could change this. Even though the first computer-assisted interpreting s…
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…
