Abstract Smart systems adapt to the surrounding environments in a number of ways. They are capable scavenge energy from available sources, sense and elaborate external stimuli adequately react. Electro Active Polymers playing main role realization smart for applications if fields such as bio inspired autonomous robotics, medicine, aerospace. This paper focus on possibility use Ionic Polymer Metal Composites class materials relevant post silicon systems. The three aspects this new technology,...

In this paper, a new model describing the human immunodeficiency virus (HIV)-acquired immuno deficiency syndrome (AIDS) epidemic spread is proposed. The improvement with respect to known models has been driven by recent results obtained from historical data collection and suggestions given World Health Organization: characteristics of diffusion, mainly body fluids, imply trivial fact that wise behaviors healthy subjects fast timely recognition positive diagnosis should reduce quite fast....

The present work deals with an Ordinary Differential Equation (ODE) model specifically designed to describe the COVID-19 evolution in Italy. is particularised on basis of National data about infection status Italian population obtain numerical solutions that effectively reproduce real data. Our epidemic a classical SEIR incorporates two compartments infected subpopulations, representing diagnosed and undiagnosed individuals respectively, additional quarantine compartment. Possible control...

This work reports the design of a 1x2 photonic logic gate controlled by an electrically metasurface, induced rectangular array points where refractive index is locally changed through application external bias. The device simulated BPM and FDTD algorithms structure under evaluation amorphous silicon MMI, joined to arrayed MOS Al/SiNx/a-Si:H/ITO be used in active-matrix pixel-fashion control output gate. MMI couplers, based on self-imaging multimode waveguides, are very compact integrated...

This work reports the design of a 1x2 photonic digital switch controlled by an electrically induced metasurface, configurated rectangular array points where refractive index is locally changed through application external bias. The device simulated using Beam Propagation Method (BPM) and Finite Difference Time Domain (FDTD) algorithms structure under evaluation amorphous silicon multimode interference (MMI), joined to arrayed Metal Oxide Semiconductor (MOS) Al/SiNx/a-Si:H/ITO be used in...

As many studies show, there is a relation between the tissue's mechanical characteristics and some specific diseases. Knowing this relationship would help early diagnosis or microsurgery. In paper, new method for measuring viscoelastic properties of soft materials at microscale proposed. This approach based on adoption microsystem whose structure can be reduced to compliant four bar linkage where connecting rod substituted by tissue sample. A procedure identify both stiffness damping...

A Brain Computer Interface (BCI) is a useful instrument to support human communication, frequently implemented by using electroencephalography (EEG).Regarding the used communication paradigm, very large number of strategies exist and, recently, self-induced emotions have been introduced.However, in general actual emotion-based BCIs are just binary, since they capable recognizing single emotion.A crucial node introduction more than emotional state for improving efficiency BCI.In order be...

This paper is dedicated to the relationship between external force applied on a point of robot end-effector and its consequent displacement in static conditions. Both are herein considered Euclidean space E(3). fact represents significant simplification approach, since it avoids some problems related absence natural positive definite metric Special Group SE(3). On other hand, such restriction allows method find closed-form solutions large class statics. The peculiar goal this investigation...

An epidemic multi-group model formed by interconnected SEIR-like structures is formulated and used for data fitting to gain insight into the COVID-19 dynamics role of non-pharmaceutical control actions implemented limit infection spread since its outbreak in Italy. The single submodels provide a rather accurate description evolution each subpopulation an extended SEIR including class asymptomatic infectives, which recognized as determinant disease diffusion. structure specifically designed...

We describe the architecture of a small remote laboratory made available by means web-based adaptive system (Mindlab2). The supports hands-on e-learning experiences with robotics and automation, performed via internet. It allows learners to access solve "problems", submit their solutions have them evaluated. problems are defined teacher, also specifying instructional aspects, such as learner's skills involved in producing solution. For each individual learner personal Student Model is...

State feedback and diffeomorphism on a given nonlinear plant to get finitely discretizable dynamics are used as first step of digital design procedure. Links with nilpotent nilpotentizable Lie algebras pointed out. The effectiveness the control procedure is demonstrated basis case study.

The present investigation is dedicated to the study of static balance at tip a planar RR robot. For this case, configuration can be interpreted, in sense, as isotropic when any force applied robot wrist yields small displacement which theoretically parallel (no matter how directed on plane). This characteristic offers many advantages and considered an optimal design goal. Unfortunately, conditions achieve such property manipulators are very restrictive, until now, only one solution adopted,...

Images and their analysis play an important role in several field of human science applications the more technology contribute to enhance capabilities possibilities, application fields grow up number importance.This multidisciplinary nature image brings different specific problems, peculiar for each area, which at a first sight can lead ways approach problem.Leaving visual and, some sense, based information extraction problems importance experiences skills are almost only support process,...

Mathematical modeling represents a useful instrument to describe epidemic spread and propose control actions, such as vaccination scheduling, quarantine, informative campaign, therapy, especially in the realistic hypothesis of resources limitations. Moreover, same representation could efficiently different scenarios, involving, for example, computer viruses spreading network. In this paper, new model describing an infectious disease possible complication is proposed; after deep-model...

A hybrid scheme is proposed for the cone guration control of a space multibody structure actuated by internal forces. The controller results from combined action continuous inner loop and digital external one. feedback designed to obtain computable sampled model; then multirate strategy computed inverting input-to-state map achieve desired orientation. Simulation are presented emphasize performances scheme.

In this paper the problem of modeling and controlling measles epidemic spread is faced.A new model proposed analysed; besides categories usually considered in modeling, susceptible, exposed, infected, removed and, less frequently, quarantine individuals, two are herein introduced: immunosuppressed subjects, that can not be vaccinated, patients with an additional complication, risky by itself but dangerous if caught togeter measles.These novelties taken into account designing scheduling...
