This paper focuses on the research on the state of the art for sensor fusion techniques, applied to the sensors embedded in mobile devices, as a means to help identify the mobile device user’s daily activities. Sensor data fusion techniques are used to consolidate the data collected from several sensors, increasing the reliability of the algorithms for the identification of the different activities. However, mobile devices have several constraints, e.g., low memory, low battery life and low processing power, and some data fusion techniques are not suited to this scenario. The main purpose of this paper is to present an overview of the state of the art to identify examples of sensor data fusion techniques that can be applied to the sensors available in mobile devices aiming to identify activities of daily living (ADLs).

This article describes the evolutionary process and the state of the art of podcasting from a theoretical and analytical perspective. This work integrates the main results of several researches carried out by the author in different countries, whose main conclusions show that podcasting has acquired a transmedia narrative texture that goes beyond the monomedia model from its beginnings, giving way to a new medium, transpodcast, which presents complex structural systems characterized by a specific multiplatform grammar and a high diversity of contents. Transpodcast is supported by the development of robust affinity communities, users and fans. These communities are built as peer-to-peer communication spaces and algorithmic environments where an evident automation of the fandom takes place.

<p>Recent and dramatic events occurred on the Italian transport networks have pointed out the urgent need for assessing the actual state of health along the national transport assets. Analogous considerations can be addressed towards the high exposition and vulnerability of the transport system to major natural events, such as floods or earthquake.</p><p>Recently, the administrations and managing companies have increasingly made use of non-destructive techniques for achieving a denser knowledge about the health of the asset.</p><p>However, one of the major limitations concerning these methods is that each technology, according to its specific features, is usually suitable for a single specific application and has very limited effectiveness for other tasks. Accordingly, the integration of datasets collected with different NDTs stands as a viable approach to fill technology-specific gaps, thereby ensuring a more comprehensive assessment of the infrastructure [1-3]. Data fusion logic can also potentially allow for further data interpretation from merging different information [4].</p><p>The EXTRATN project aims at overcoming the state-of-the-art research in the field of non-destructive monitoring of linear infrastructures and, through a “data fusion” logic, at achieving a comprehensive rate of knowledge about the actual condition of the asset. The addressed concept is a “fully sensed infrastructure”, being sensed by different technologies and with different scopes. Specifically, interferometric synthetic aperture radar (DInSAR), Laser Imaging Detection and Ranging (LiDAR), Ground-penetrating Radar (GPR) and Falling Weight Deflectometer (FWD) are considered to the purpose.</p><p>A system of transport infrastructure being located in the Province of Salerno (IT), within an area subjected to hydrogeological risk, has been selected as a study case for the integrated approach. This system includes a motorway, a rural highway and a railway.</p><p>As a major advantage with respect to the state-of-the-art, such a methodology allows for analysing the evolution trend of the on-going distresses, meaning a significant upgrade of the monitoring activities that may provide valuable information for a priority-based scheduling of the maintenance.</p><p>Moreover, such an approach enables to simultaneously monitor exogenous and endogenous events that may lead to a decrease of the safety, functionality or strength conditions.</p><p>The research is supported by the Italian Ministry of Education, University and Research under the National Project “Extended resilience analysis of transport networks (EXTRA TN): Towards a simultaneously space, aerial and ground sensed infrastructure for risks prevention”, PRIN 2017, Prot. 20179BP4SM.</p><p> </p><ol><li>Liu W, Chen S, Hauser E (2011) LiDAR-based bridge structure defect detection.

This paper is a general description of the state-of-the-art on the European and colonial building techniques found in wooden buildings that currently exist. The description of the use and diffusion of the wooden structures is made by a brief explanation of the relative structural systems, as well as the peculiarities of the elements that compose it, its operating principles, the points of weakness and the joints used. Thus, the English and German techniques of structural timber frameworks are described in detail. On the other hand, other structural techniques and their evolution are presented through a review of works and documents that describe them accurately.

The purpose of this paper is to provide a review and an assessment of the state-of-the-art in the area of statistical and equivalent linearization in the analysis of nonlinear stochastic systems. Included in the discussion are systems subjected to stationary and nonstationary excitations as well as parametrically excited systems. A variety of linearization criteria are discussed together with accuracy associated with these procedures. This review also includes some applications of equivalent linearization to the study of dynamics of mechanical and structural systems subjected to environmental loads such as wave loads and earthquake excitations. Limitations of current procedures of equivalent linearization are mentioned and suggestions for areas of further research are made.
