Nanostructured Pb electrode for innovative lead-acid battery
2017
Lead-acid batteries are widely used for energy storage, due to a well-established and reliable technology. Over the years, various studies for improving the performance of this battery have been performed. The main goal is to replace conventional plates with innovative electrodes having good stability, high capacity and high surface area. In particular, it is necessary to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface, and to guarantee good electrical continuity during repeated charge/discharge cycles. To achieve these goals, the attention was focused on nanostructured electrodes. Up-to-date, two principal approaches have been followed. In t…
The upgraded HADES trigger and data acquisition system
2011
The HADES experiment is a High Acceptance Di-Electron Spectrometer located at GSI in Darmstadt, Germany. Recently, its trigger and data acquisition system was upgraded. The main goal was to substantially increase the event rate capability by a factor of up to 20 to reach 100 kHz in light and 20 kHz in heavy ion reaction systems. The total data rate written to storage is about 400 MByte/s in peak.In this context, the complete read-out system was exchanged to FPGA-based platforms using optical communication. For data transport a general-purpose real-time network protocol was developed to meet the strong requirements of the system. In particular, trigger information has to reach all front-end …

Performance evaluation of non volatile memories with a low cost and portable automatic test equipment
2017
This paper presents a versatile and portable test equipment, called portable ATE for research and development of non-volatile memories functionalities. The system is based on STM32-NUCLEO assembled with a custom designed daughter board, in order to host non-volatile memories test-chips, to manage the needed power supplies and generate suitable signals stimuli for correct operations. The system is controlled and programmed by a personal computer, via USB interface. In particular the system can perform: memory reading, writing and erasing, with settings flexibility on time and voltage levels; Electrical Stress Tests (Drain, Gate and Bulk Stress); Cycling Tests; debugging algorithms (erase or …

Agronomic Evaluation of Ethiopian Mustard (brassica Carinata A. Braun) Germplasm and Physical-energy Characterization of Crop Residues in a Semi-arid…
2017
Brassica carinata A. Braun is one of the most interesting oilseed crops suited to arid and semi-arid areas for energy purposes. Several studies have highlighted the possibility of introducing this species into cropping systems, typical of Mediterranean region. The aims of this study were to evaluate the agronomic performance of Brassica carinata germplasm under Mediterranean climatic conditions and to assess the physical and energy characteristics of crop residues and pellets made from the residues. A total of 20 different accessions of Brassica carinata were compared in a semi-arid area of Sicily (Italy). In the two-year test period, the main morphological and yield parameters of the acces…
FlexibleSUSY—A spectrum generator generator for supersymmetric models
2019
This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We introduce FlexibleSUSY, a Mathematica and C++ package, which generates a fast, precise C++ spectrum generator for any SUSY model specified by the user. The generated code is designed with both speed and modularity in mind, making it easy to adapt and extend with new features. The model is specified by supplying the superpotential, gauge structure and particle content in a SARAH model file; specific boundary conditions e.g. at the GUT, weak or intermediate scales are defined in a separate F...

Parallelization of adaptive MC integrators
2019
Abstract Monte Carlo (MC) methods for numerical integration seem to be embarrassingly parallel on first sight. When adaptive schemes are applied in order to enhance convergence however, the seemingly most natural way of replicating the whole job on each processor can potentially ruin the adaptive behaviour. Using the popular VEGAS-Algorithm as an example an economic method of semi-micro parallelization with variable grain-size is presented and contrasted with another straightforward approach of macro-...
