We tackle the problem of a network switch enforcing fair bandwidth sharing of the same link among many TCP-like senders. Most of the mechanisms to solve this problem are based on complex scheduling algorithms, whose feasibility becomes very expensive...
The emerging trend of network devices with configurable data planes is pushing software switches as convenient playgrounds for experimenting novel programming paradigms and abstractions. OfSoftSwitch is a popular tool for carrying on such...
The large availability of multi--gigabit network cards for commodity PCs requires network applications to potentially cope with high volumes of traffic. However, computation intensive operations may not catch up with high traffic rates and need to be...
The evolution of commodity PCs towards multi– core processing platforms equipped with high–speed network interfaces makes them reasonable and cost effective targets for the implementation of generic network functions. In addition, the availability of...
This demonstration allows attendees to experience skin stretch as haptic feedback in conjunction with a prosthetic hand to handle and complete tasks with everyday objects. The closure position of the Pisa/IIT SoftHand is indicated to the user through...
Grasp and manipulation is a complex task, deceivingly simple to accomplish for humans in everyday life, yet challenging when it has to be implemented in a robotic hand. There is a trend in literature to use information obtained from studies on human...
Human hands are capable of a variety of movements, thanks to their extraordinary biomechanical structure and relying on the richness of human tactile information. Recently, soft robotic hands have opened exciting possibilities and, at the same time, new...
Myoelectric prostheses have seen increased application in clinical practice and research, due to their potential for good functionality and versatility. Yet, myoelectric prostheses still suffer from a lack of intuitive control and haptic feedback, which...
An effective robotic wrist represents a key enabling element in robotic manipulation, especially in prosthetics. In this paper, we propose an under-actuated wrist system, which is also adaptable and allows to implement different under-actuation schemes....
As robotic devices are applied to problems beyond traditional manufacturing and industrial settings, we find that interaction between robots and humans, especially physical interaction, has become a fast developing field. Consider the application of...

The rich variety of human upper limb movements requires an extraordinary coordination of different joints according to specific spatio-temporal patterns. However, unvealing these motor schemes is a challenging task. Principal components have been often...
Despite the importance of softness, there is no evidence of wearable haptic systems able to deliver controllable softness cues. Here, we present the Wearable Fabric Yielding Display (W-FYD), a fabric-based display for multi-cue delivery that can be worn...
Humans are able to intuitively exploit the shape of an object and environmental constraints to achieve stable grasps and perform dexterous manipulations. In doing that, a vast range of kinematic strategies can be observed. However, in this work we...
ABSTRACT: Detecting and tracking moving objects in real-time from an airborne infrared (IR) camera offers interesting possibilities in video surveillance, remote sensing and computer vision applications, such as monitoring large areas simultaneously,...
A simulator of weather radar signals can be exploited as useful reference in many applications, such as weather forecasting and now-casting models or training for aircraft trajectory optimization to reduce flight hazard. However, it must be well...
In this study, we investigate some counterintuitive but frequent performance issues that arise when doing high-speed networking (or I/O in general) with Virtual Machines (VMs). VMs use one or more single-producer/single-consumer systems to exchange I/O...
A compact differential voltage reference cell, which combines an original switched capacitor integrator with a digitally programmable bandgap core, is presented. The two-stage integrator maintains an always-valid output voltage while performing...
Network Function Virtualization has been touted as the silver bullet for tackling a number of operator problems, including vendor lock-in, fast deployment of new functionality, converged management, and lower expenditure since packet processing runs on...
A compact sub-1V class-AB operational amplifier to be used as a building block for low-voltage switched-capacitor architectures is presented. The proposed amplifier works properly with supply voltages in the range 0.9 V - 1.4 V, providing a...
