This paper investigates the utilization of satellite broadcast signals such as DVB-S and DVB-S2 as illuminator of opportunity for passive radar imaging techniques like SAR or ISAR. It includes an analysis of the key elements of the structure of the...
This work analyzes a mmWave single-cell network, which comprises a macro base station (BS) and an overlaid tier of small-cell BSs using a wireless backhaul for data traffic. We look for the optimal number of antennas at both BS and small-cell BSs that...
Abstract Ordered arrays of silicon nano- to microscale pillars are used to enable biomolecular trafficking into primary human cells, consistently demonstrating high transfection efficiency can be achieved with broader and taller pillars than reported to...
Advanced Functional Materials, 2017, 27, 1604310 Abstract In this work the authors report on the controlled electrochemical etching of high-aspect-ratio (from 5 to 100) structures in silicon at the highest etching rates (from 3 to 10 μm min1) at room...
Electrochimica Acta 187 (2016) 552–559 Abstract In-silicon hierarchical networks of ordered out-of-plane macropores interconnected by high-density secondary in-plane pores are prepared by controlled electrochemical etching of n-type silicon in HF:H2O2...
U-PHOS (Upgraded PHP Only for Space) is a project developed by a team of students from the University of Pisa with the goal to analyze and characterize the behavior of a Pulsating Heat Pipe (PHP), one of the most attractive two phases passive systems...
In the last decades, smart power wheelchairs have being used by people with motor skill impairment in order to improve their autonomy, independence and quality of life. The most recent power wheelchairs feature many technological devices, such as laser...
ABSTRACT: Tridimensional reconstruction of areas and objects of interest from images acquired from aerial drones plays a key role in numerous fields, from the less critical, like urban planning and archeological area survey, to the most critical, like...
ABSTRACT: We developed an algorithm for automatically detecting small and poorly contrasted (dim) moving objects in real-time, within video sequences acquired through a steady infrared camera. The algorithm is suitable for dierent situations since it...

Abstract —The experimental characterization of a new DC/DC converter for high voltage, up to 60 V, automotive applications is proposed in the paper. A summary description of the inductorless converter is showed to understand the measurement results. The...
Abstract —Practical techniques to reduce electromagnetic interference (EMI) for integrated DC/DC converters are discussed in the paper. As application case study a 48 V DC/DC converter for electric/hybrid cars is considered. Firstly, an EMI filter with...
Abstract. DC/DC applications in automotive market are expected to require new system speci cations in next years. Because of the spreading of electrical cars, the power line at 48 V will be very common. Moreover, the converter chips and external...
Abstract. The paper analyses the trend in packaging for low-power integrated circuits (IC) and the principal failures that can occur. A Fault-tree (FT) analysis is proposed, as well an analysis of the failure distribution (FD), which can be useful in...
This study describes an actuated bioreactor which mimics the pulsatile contractile motion of the intestinal barrier using electro-responsive elastomers as smart materials that undergo deformation upon electrical stimulation. The device consists of an...
The study of nanomaterial translocation across epithelial barriers is often hindered by the low permeability of transwell membranes to nanoparticles. To address this issue ultra-thin poly(L-lactic acid) nanofilms with zero tortuosity micropores were...
The location of Internet hosts is frequently used in distributed applications and networking services. Examples include customized advertising, distribution of content, and position-based security. Unfortunately the relationship between an IP address...
Robots are gradually but steadily being introduced in our daily lives. A paramount application is that of education, where robots can assume the role of a tutor, a peer or simply a tool to help learners in a specific knowledge domain. Such endeavor...
This paper presents the EU EASEL project, which explores the potential impact and relevance of a robot in educational settings. We present the project objectives and the theorectical background on which the project builds, briefly introduce the EASEL...
This work introduces the concept of "personality-friendly" objects. Its goal is to investigate the relationship that can exist between specific interactive products and the users' personalities. Nowadays, it seems that every object being advertised and...
