An Embedded Processor for Metabolic Networks Optimization

2011

In recent years biological processes modelling and simulation have become two key issues in analyzing complex cellular systems. The computational requirements suggest to investigate alternative solutions to the common supercomputers and clusters in order to optimize and overcome computational bottleneck. The goal of this work is the design and the realization of an embedded processor for metabolic networks optimization in order to examine their behaviour and robustness under malfunctions of one or more nodes. The embedded processor has been prototyped on the Celoxica RC203E board, equipped with programmable FPGA technologies. A case studied outlining the E. Coli bacteria metabolic network i…

Robust and Efficient Data Gathering for Wireless Sensor Networks

2006

This paper describes a new strategy for data gathering in wireless sensor networks that takes into account the need for both energy saving, typical of such networks, and for a reasonable tradeoff between robustness and efficiency. The proposed algorithm implements an efficient strategy for retransmission of lost packets by discovering alternative routes and making clever use of multiple paths when necessary; in order to do that we build upon the general framework presented in recent works, that provided a formulation of duplicate and order insensitive aggregation functions, and by taking advantage of some intrinsic characteristics of the wireless sensor networks, we exploit implicit acknowl…

An evaluation of recent local image descriptors for real-world applications of image matching

2019

This paper discusses and compares the best and most recent local descriptors, evaluating them on increasingly complex image matching tasks, encompassing planar and non-planar scenarios under severe viewpoint changes. This evaluation, aimed at assessing descriptor suitability for real-world applications, leverages the concept of approximated overlap error as a means to naturally extend to non-planar scenes the standard metric used for planar scenes. According to the evaluation results, most descriptors exhibit a gradual performance degradation in the transition from planar to non-planar scenes. The best descriptors are those capable of capturing well not only the local image context, but als…

An Evolution of the Non-Parameter Harris Affine Corner Detector: A Distributed Approach

2009

A parallel version of a new automatic Harris-based corner detector is presented. A scheduler to dynamically and homogeneously distribute high computational workload on heterogeneous parallel architectures such as Grid systems has been implemented to speedup the whole procedure. Experimental results show the robustness of the underlying scheduler, which can be easily exploited in various automatic image analysis systems.

Biologically Inspired Hardware: Status and Perspectives (Invited Talk)

2012

Biologically Inspired Computing places its emphasis on robustness, adaptability, and emergent organization considering the interaction of many processes. Bio-inspired algorithms exhibit strength and flexibility in poorly defined or time-variable tasks, as well as when the global behaviour is achieved by simple interacting of species or agents. The above philosophy links various disciplines such as artificial and computationally intelligence, evolutionary computation, bio-robotics, agent-based systems, and Digital Ecosystems. In this paper, the main branches of bio-inspired computing are briefly discussed. Successively, the impact of the bioinspired paradigm on innovative hardware structures…

Lo strano caso di Cornelia Bandi (1731). Un dibattito sulla «combustione spontanea» nel XVIII secolo

2014

Il saggio ricostruisce il dibattito di matrice medico-scientifica scaturito da un caso di cronaca avvenuto a Cesena nel 1731, quando il cadavere della nobildonna Cornelia Bandi veniva trovato in stato di parziale incenerimento in una camera da letto che non presentava tracce alcune di rogo. Emergeva nel mondo scientifico ed erudito dell’epoca un dibattito che coinvolgeva alcuni dei personaggi più influenti della cultura coeva, da Giuseppe Bianchini a Scipione Maffei e Ludovico Antonio Muratori, sino a Immanuel Kant, e che più avanti, in un contesto culturale profondamente mutato, raccoglieva l’interesse di Giacomo Leopardi e Charles Dickens. Appare con tutta evidenza la differenza tra la pe…

Fast Channel Estimation in the Transformed Spatial Domain for Analog Millimeter Wave Systems

2021

Fast channel estimation in millimeter-wave (mmWave) systems is a fundamental enabler of high-gain beamforming, which boosts coverage and capacity. The channel estimation stage typically involves an initial beam training process where a subset of the possible beam directions at the transmitter and receiver is scanned along a predefined codebook. Unfortunately, the high number of transmit and receive antennas deployed in mmWave systems increase the complexity of the beam selection and channel estimation tasks. In this work, we tackle the channel estimation problem in analog systems from a different perspective than used by previous works. In particular, we propose to move the channel estimati…
