KIND-DAMA: A modular middleware for Kinect-like device data management

2018

In the last decades, we have witnessed a growing interest toward touchless gestural user interfaces. Among other reasons, this is due to the large availability of different low-cost gesture acquisition hardware (the so-called “Kinect-like devices”). As a consequence, there is a growing need for solutions that allow to easily integrate such devices within actual systems. In this paper, we present KIND-DAMA, an open and modular middleware that helps in the development of interactive applications based on gestural input. We first review the existing middlewares for gestural data management. Then, we describe the proposed architecture and compare its features against the existing similar so…

Internet of things: why we are not there yet

2014

Twenty-one years past since Weiser's vision of ubiquitous computing (UbiComp) has been written, and it is yet to be fully fulfilled despite of almost all the needed technologies already available. Still, the widespread interest in UbiComp and the results in some of its fields pose a question: why we are not there yet? It seems we miss the 'octopus' head. In this paper, we will try to depict the reasons why we are not there yet, from three different points of view: interaction media, device integration and applications.

Body Area Networks and Healthcare

2014

Derived from Wireless Sensor Networks, Body Area Networks, comprise a wide range of typologies with sensor nodes placed on, close to, or implanted in the body that measure physiological signs. The availability of compact mobile computing devices makes it possible to integrate traditional healthcare with new powerful means. New paradigms in public health are arising from these developments, such as e-health and mHealth, and new converging applications can be envisioned. Physiological data acquisition provided by BANs may give care providers a unobtrusive real-time view on patient’s health. On the other hand, the patient may be informed, assisted and even given the proper treatment by care pr…

Through Different Eyes. Feminine Science and Literature in Early Modern Culture

2016

The question of a dominant model of vision will be at stake in this essay, which will try to provoke other questions on the ways in which non-dominant models of vision have tried to spread out in a particularly revolutionary and dramatic period. This century is the 17th and the non-dominant model of vision is that of the female gaze. Particularly the works of three English writers – Margaret Cavendish, Aphra Behn, Eliza Haywood – and their commitment with the matter of gaze will be analysed.

La Sicilia negli Orsi di Dino Buzzati e Lorenzo Mattotti

2022

Nella fiaba illustrata di Dino Buzzati La famosa invasione degli orsi in Sicilia (1945) e nella sua trasposizione filmica ad opera di Lorenzo Mattotti (2019) l’ambientazione siciliana è determinante. In entrambi i casi la Sicilia è un’isola con un grande vulcano – trasfigurata in un ambiente fantastico o riscritta secondo alcuni stereotipi – che i due autori utilizzano con accezioni diverse nella costituzione dell’ecosistema delle loro narrazioni. Soltanto attraverso una comparazione tra le due opere sarà possibile distinguere la rappresentazione delle due Sicilie che vengono raccontate con un intervallo di circa settanta anni. Se non si considera la storia degli Orsi soltanto una fiaba per…

Premessa a: Cultura visuale in Italia : immagini, sguardi, dispositivi

2022

Questo volume raccoglie le riflessioni maturate durante il convegno internazionale “Cultura visuale in Italia. Prospettive della ricerca” svoltosi a Palermo tra il 19 e il 21 marzo 2018. Si è trattato di un incontro che ha visto la partecipazio- ne di molti dei protagonisti della ricerca italiana in quell’ambito “indisciplinato” – per usare una felice espressione di W.J.T. Mitchell – che è la cultura visuale, accademica e non, un campo di studi che ha ormai solide tradizioni internazionali e anche notevoli ricadute accademiche, come dimostra la presenza a Palermo di docenti che, pur provenendo da “altre” discipline, la comparatistica letteraria, l’estetica, la storia dell’arte, la mediologi…

Interventionist research in management accounting: promoting engagement through face-to-face dialogues

2023

PurposeThis paper explores face-to-face dialogues between practitioners and interventionist researchers in the management accounting (MA) field during real-time interactions for the development of accounting devices. It aims to shed light on whether and how these dialogues can affect the construction of meanings around the devices, thereby influencing the course of interventionist research (IVR) projects.Design/methodology/approachThis study presents a reflective analysis (both in itinere and ex-post) of an IVR project conducted by one of the authors within a healthcare organisation. It draws on a dialogical perspective to delve into the conversations between the author and the organisation…

A Configuration of 3-phase Traction Inverter Employing {SiC} Devices

2022

In the scenario of a more and more sustainable society, an increasing electrification in different fields, such as mobility and industrial applications, is foreseen in the next decades. As far as power electronics is concerned, a challenging perspective is represented by achieving higher and higher switching frequencies while maintaining high voltage and low power losses. To do that, emerging semiconductor technologies are supposed to be increasingly employed, as well as innovative topologies of connections among switching devices. Among them, the cascode configuration can notably contribute to achieve high levels of dV/dt without losing efficiency. In this paper, a 3-phase Pulse Width Modu…

GaN and SiC Device Characterization by a Dedicated Embedded Measurement System

2023

This work proposes a comparison among GaN and SiC device main parameters measured with a dedicated and low-cost embedded system, employing an STM32 microcontroller designed to the purpose. The system has the advantage to avoid the use of expensive laboratory measurement equipment to test the devices, allowing to obtain their behavior in operating conditions. The following KPIs (Key Performance Indicators) are measured and critically compared: threshold voltage, on-resistance and input capacitance. All the measurements are carried out in a short time interval and on a wide range of switching frequencies, ranging from 10 kHz to 1 MHz. This investigation is focused on the deviation of the figu…
