Today, video cameras are a very common way to gather data from physical processes also thanks to the technological evolution, seen both for the acquisition devices and the visualization/elaboration ones, which brought high quality at low costs. The video world, unfortunately, still suffers from the legacies of the early analog video era, so that engineers(More)
Biometric identification systems are defined as systems exploiting automated methods of personal recognition based on physiological or behavioural characteristics. Among these, fingerprints are very reliable biometric identifiers. Trying to fasten the image processing step makes the recognition process more efficient, especially concerning embedded systems(More)
An accelerator based on field-programmable gate array (FPGA) technology accelerates double-precision floating-point operations present in the energy calculation of Monte Carlo-Metropolis simulations. The accelerator uses COTS components and is scalable in terms of clock frequency, memory capability, and number of computing units. It could also be part of a(More)
Peach was domesticated in China more than four millennia ago and from there it spread world-wide. Since the middle of the last century, peach breeding programs have been very dynamic generating hundreds of new commercial varieties, however, in most cases such varieties derive from a limited collection of parental lines (founders). This is one reason for the(More)
Binary traits are often encountered in plant (and animal) breeding. These include resistance/susceptibility to diseases or the presence/absence of a given characteristic. Root vigor in sugar beet is related to nutrient uptake from the soil and sugar yield and can be classified as either high or low, thus providing an example of binary trait of agronomic(More)
Genomic selection based on genotyping-by-sequencing (GBS) data could accelerate alfalfa yield gains, if it displayed moderate ability to predict parent breeding values. Its interest would be enhanced by predicting ability also for germplasm/reference populations other than those for which it was defined. Predicting accuracy may be influenced by statistical(More)
In recent years, the use of genomic information in livestock species for genetic improvement, association studies and many other fields has become routine. In order to accommodate different market requirements in terms of genotyping cost, manufacturers of single nucleotide polymorphism (SNP) arrays, private companies and international consortia have(More)
Genotyping-by-sequencing (GBS) is a rapid and cost-effective genome-wide genotyping technique applicable whether a reference genome is available or not. Due to the cost-coverage trade-off, however, GBS typically produces large amounts of missing marker genotypes, whose imputation becomes therefore both challenging and critical for later analyses. In this(More)
Biometric identification systems exploit automated methods of recognition based on physiological or behavioural people characteristics. Among these, fingerprints are very affordable biometric identifiers. In order to build embedded systems performing real-time authentication, a fast computational unit for image processing is required. In this paper we(More)
