Fast spiking neural network architecture for low-cost FPGA devices
2012
Spiking Neural Networks (SNN) consist of fully interconnected computation units (neurons) based on spike processing. This type of networks resembles those found in biological systems studied by neuroscientists. This paper shows a hardware implementation for SNN. First, SNN require the inputs to be spikes, being necessary a conversion system (encoding) from digital values into spikes. For travelling spikes, each neuron interconnection is characterized by weights and delays, requiring an internal neuron processing by a Postsynaptic Potential (PSP) function and membrane potential threshold evaluation for a postsynaptic output spike generation. In order to model a real biological system by arti…
Digital background calibration algorithm and its FPGA implementation for timing mismatch correction of time-interleaved ADC
2019
Sample time error can degrade the performance of time-interleaved analog to digital converters (TIADCs). A fully digital background algorithm is presented in this paper to estimate and correct the timing mismatch errors between four interleaved channels, together with its hardware implementation. The proposed algorithm provides low computation burden and high performance. It is based on the simplified representation of the coefficients of the Lagrange interpolator. Simulation results show that it can suppress error tones in all of the Nyquist band. Results show that, for a four-channel TIADC with 10-bit resolution, the proposed algorithm improves the signal to noise and distortion ratio (SN…
A novel digital control for DC/DC converters to improve steady-state performances
2006
This paper describes an innovative digital PWM control implementation for low voltage, high current DC-DC converters. The proposed technique, based on the use of a low resolution DAC, improves steady-state performances, minimizing limit cycle effects. The novel technique is tested on a FPGA-based single phase buck converter operating at 250 kHz. A detailed description of the proposed architecture is given and test results, simulation and experimental ones, are shown

Muzejpedagoģija vizuālās mākslas programmas īstenošanā 1.-6.klasē
2018
Muzejpedagoģija ir izglītības joma, kuras aktualitāti nosaka vizuālās mākslas mācību standarts, programma, projekts „Kompetenču pieeja mācību saturā” un Sarmītes Sedliņas maģistra darbs ar nosaukumu „Muzejpedagoģija vizuālās mākslas programmas īstenošanā 1.- 6. klasē” izstrādāts ar mērķi veicināt muzejpedagoģijas izmantošanu mācību procesā. Maģistra darba pētījuma problēma ir muzejpedagoģijas realizācija vizuālās mākslas mācību satura apguvē, un par pētījuma objektu tiek izmantots vizuālās mākslas saturs un organizācijas formas sākumskolā. Pētījumā analizēts muzejpedagoģijas piedāvājums vizuālās mākslas apguvei Latvijā un veikta vizuālās mākslas skolotāju un muzejpedagogu viedokļu apkopošan…
MODELLI DI SYSTEM DYNAMICS PER IL MIGLIORAMENTO DELLA PERFORMANCE AZIENDALE. VERSO UN SISTEMA DI PROGRAMMAZIONE E CONTROLLO PER LO SVILUPPO SOSTENIBI…
2009
Il libro affronta il tema del governo dello sviluppo sostenibile e del miglioramento della performance aziendale attraverso sistemi di programmazione e controllo che si avvalgano di modelli di system dynamics. Il testo è corredato da numerosi casi applicativi e modelli di simulazione. I casi e i modelli riportati derivano da applicazioni realizzate presso aziende operanti in settori diversi (es. telecomunicazioni, assicurazioni, tessile, servizi bancari, produzione su commessa, commercio all’ingrosso) e con riferimento a problematiche differenti. Gli ambiti decisionali analizzati con i modelli riportati nel libro tendono a coprire gli aspetti maggiormente critici della gestione strategica e…
Šaha taktikas treniņprogramma
2017
Kvalifikācijas darba mērķis ir izstrādāt programmatūru, kas palīdzēs šahistiem uzlabot savas šaha taktiskās domāšanas spējas interaktīvi risinot šaha uzdevumus. Projekta ietvaros tika izveidota programmatūras prasību specifikācija un programmatūras projektējuma apraksts, tika veikta testēšana un tā tika aprakstīta dokumentācijā. Programma tiek veidota lai šahisti varētu trenēt sava taktiskās domāšanas spējas ar datora palīdzību, tādejādi papildinot savu trenēšanās iespēju klāstu un paātrinot treniņu procesu, jo atšķirībā no ierastās šahistu trenēšanās metodes, kur šahist izpēta jau izspēlētas šaha spēles reāla galdiņa, šaha situācijas tiek veidotas grafiskajā vidē, aiztaupot laiku, kas tiek…
The readout system and the trigger algorithm implementation for the UFFO Pathfinder
2012
Since the launch of the SWIFT, Gamma-Ray Bursts (GRBs) science has been much progressed. Especially supporting many measurements of GRB events and sharing them with other telescopes by the Gamma-ray Coordinate Network (GCN) have resulted the richness of GRB events, however, only a few of GRB events have been measured within a minute after the gamma ray signal. This lack of sub-minute data limits the study for the characteristics of the UV-optical light curve of the short-hard type GRB and the fast-rising GRB. Therefore, we have developed the telescope named the Ultra-Fast Flash Observatory (UFFO) Pathfinder, to take the sub-minute data for the early photons from GRB. The UFFO Pathfinder has…
La Terra Vacua tra destino, rinuncia e stato d’animo
2020
La vasta area di quello che abitualmente chiamiamo, e certamente non appropriatamente, piazza Magione o piano della Magione, la Terra Vacua, ovvero il grande vuoto nel cuore della Kalsa, come più poeticamente è stato definito da Carmelo Lo Curto, con le sue molteplici contraddizioni, per essere il risultato di travagliate vicende tragiche e luttuose, obliteratrici di una condizione diametralmente opposta a quella percepibile sinesteticamente oggi o nel recente passato, può considerarsi più che mai una vera e propria sineddoche e figura metonimica della città. Cioè la parte rappresentativa del tutto. La parte che incarna in sé, nella sua odierna scena di condizione talvolta caratterizzata da…
