Enabling Multimodal Interaction in XPL – the eXtensible Presentation Language

2007

This paper introduces the multimodal extension of the eXtensible Presentation architecture and Language (XPL), a framework aimed at streamlining multi-channel interface design process and enabling full component reuse. XPL incorporates a presentation language based on design pattern paradigm, which supplies a clear distinction between the presentation layer and the corresponding programming logic, promoting contents aggregation and a variety of event handlers described without relying on a (procedural) scripting language. In this paper, the design pattern concept is extended to voice-based interaction, and two verbal design pattern (VeDP) are introduced along to their visual counterparts. T…

Brevi note sulla qualificazione giuridica dei beni costituenti la rete ferroviaria

2015

The paper synthetically describes how Italian courts and scholars interpret- ed the legal transformations occurred to the railway market, and notably to the rail-network’s infrastructure components property regulation, since the end of the twentieth century. The authors refute the (prevailing) opinion assuming a substantial continuity between the current stage of regulation and the regime of public property provided by the 1942 civil code; they show the reasons why, on the contrary, the rail-network components have to be considered as goods sub- ject to private property law both on the formal and the substantial floor. For this purpose, the paper emphasizes how the public interests aimed by…

The role of working memory on writing processes.

2021

Literature has extensively demonstrated the coordination role of working memory (WM) in complex tasks such as writing. However, previous studies mostly concentrated on the relation between passive WM (e.g., WM span) components and specific writing tasks (e.g., dictation). Here, we aimed to investigate the relationship between different writing skills and the performance on a WM updating task measuring the more active components of WM. From a pool of 160 Italian pupils (grades 3–5), we selected 46 children divided in two groups based on their WM updating performance. The first group consisted of 21 children with low WM updating performance (≤10th percentile), the second group consisted of 25…

A multidimensional hydrodynamic code for structure evolution in cosmology

1996

A cosmological multidimensional hydrodynamic code is described and tested. This code is based on modern high-resolution shock-capturing techniques. It can make use of a linear or a parabolic cell reconstruction as well as an approximate Riemann solver. The code has been specifically designed for cosmological applications. Two tests including shocks have been considered: the first one is a standard shock tube and the second test involves a spherically symmetric shock. Various additional cosmological tests are also presented. In this way, the performance of the code is proved. The usefulness of the code is discussed; in particular, this powerful tool is expected to be useful in order to study…

Spatial noise-aware temperature retrieval from infrared sounder data

2020

In this paper we present a combined strategy for the retrieval of atmospheric profiles from infrared sounders. The approach considers the spatial information and a noise-dependent dimensionality reduction approach. The extracted features are fed into a canonical linear regression. We compare Principal Component Analysis (PCA) and Minimum Noise Fraction (MNF) for dimensionality reduction, and study the compactness and information content of the extracted features. Assessment of the results is done on a big dataset covering many spatial and temporal situations. PCA is widely used for these purposes but our analysis shows that one can gain significant improvements of the error rates when using…

Blind multi-user detection by fast fixed point algorithm without prior knowledge of symbol-level timing

2003

We consider the estimation of the source process of the desired user an the downlink of a code-division multiple access (CDMA) communication system. In downlink signal processing, only the code of the mobile telephone user is known, while the codes of the interfering users are unknown. Blind source separation or independent component analysis is an approach offering the solution to this problem. In this work we apply the fast fixed point algorithm to the separation problem. The algorithm is based on fourth-order statistics optimization. Knowledge about the symbol level timing has to be known only coarsely.

PPG/ECG Multisite Combo System Based on SiPM Technology

2019

Two versions of a PPG/ECG combined system have been realized and tested. In a first version a multisite system has been equipped by integrating 3 PPG optodes and 3 ECG leads, whereas in another setup a portable version has been carried out. Both versions have been realized by equipping the optical probes with SiPM detectors. SiPM technology is expected to bring relevant advantages in PPG systems and overcome the limitations of physiological information extracted by state of the art PPG, such as poor sensitivity of detectors used for backscattered light detection and motion artifacts seriously affecting the measurements repeatability and pulse waveform stability. This contribution presents t…

Ein Nadelelektroden-Isolationsverstärker für biomechanische Untersuchungen - An Isolation Amplifier for Biomechanical Investigations with Needle Elec…

1994

In our laboratory for biomechanics, a new isolation amplifier was developed with which to record the electromyographic activity of muscles inaccessible to surface electrodes, in particular that of the rotator cuff. Our basic premisses were maximum safety for the patient or subject investigated, and optimal signal processing. These were achieved by a triple galvanic separation of the patient/subject from the battery power supply and the signal cables and by careful selection of the electronic components.

Identification des gènes impliqués lors de l'établissement de Lactobacillus casei dans l'intestin et caractérisation de l'opéron LSEI_0219-0221

2014

In bacteria which are in direct contact with their environment, genes transcription and proteins synthesis are efficiently regulated at each change of environmental parameters to allow cell survival. For intestinal commensal bacteria, these regulations must also allow symbiotic interactions and colonization whose molecular mechanisms, so far little known, are probably related, among others, to the bacteria surface (molecules exposed and secreted…). Lactobacillus casei, a commensal bacterium, has about 330 predicted genes involved in the composition and functionality of the cell surface. To have a global view of the whole genes involved in the establishment of L. casei in the gut, a reverse …
