A Computationally Efficient Online/Offline Signature Scheme for Underwater Wireless Sensor Networks
2022
Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computation requirements. In this researc…

The Promise and Deception of Participation in Welfare Services for Unemployed Young People
2018
This study examined the role of welfare services in the participative citizenship of young people under 30 years of age outside the labour market. Thematic content analysis of the government’s white papers regarding participation policies, as well as participatory action research projects in two Finnish towns, were used to identify factors that enable or hinder participation for this group of service users. The paradigm of participation was critically examined with reference to the theoretical framework of Max Horkheimer and Theodor Adorno’s “dialectic of Enlightenment”, which proposes the parallel existence of the promise and the deception of Enlightenment. The results indicated that user …
Sustainable Working Life in a Swedish Twin Cohort : A Definition Paper with Sample Overview
2021
Background: A unified or consensus definition of “sustainable working life” remains lacking, although studies investigating risk factors for labour market exit are numerous. In this study, we aimed (1) to update the information and to explore a definition of “sustainable working life” via a systematic literature review and (2) to describe the working life trajectories via the prevalence of sickness absence (SA), disability pension (DP), and unemployment in a Swedish twin cohort to provide a sample overview in our Sustainable Working Life-project. Methods: A systematic literature review was conducted to explore the studies with the search phrase “sustainable working life” in PubMed, PsycInfo…

Promoting Students’ Health at University: Key Stakeholders, Cooperation, and Network Development
2021
Background: Cooperation among university units is considered a cornerstone for the promotion of students' health. The underlying mechanisms of health-promoting networks at universities have rarely been examined so far. Shedding light on partnerships is generally limited to the naming of allied actors in a network. Objectives and Methods: In this study, we used network analysis intending to visualize and describe the positions and characteristics of the network actors, and examine organizational relationships to determine the characteristics of the complete network. Results: The network analysis at hand provides in-depth insights into university structures promoting students' health comprisi…
IEA EBC Annex83 Positive Energy Districts
2021
At a global level, the need for energy efficiency and an increased share of renewable energy sources is evident, as is the crucial role of cities due to the rapid urbanization rate. As a consequence of this, the research work related to Positive Energy Districts (PED) has accelerated in recent years. A common shared definition, as well as technological approaches or methodological issues related to PEDs are still unclear in this development and a global scientific discussion is needed. The International Energy Agency’s Energy in Buildings and Communities Programme (IEA EBC) Annex 83 is the main platform for this international scientific debate and research. This paper describes the challeng…
Urban Flood Prediction through GIS-Based Dual-Coupled Hydraulic Models
2022
Propagation of pluvial floods in urban areas, occurring with return time periods of few years, can be well solved using dual models accounting for the mutual relationship between the water level in the streets and the discharges inside the sewer pipes. The extended WEC-flood model (EWEC), based on the use of unstructured triangular meshes and a diffusive formulation of the momentum equations in both the 2D and the 1D lower domains, is presented along with its novelty, limits, and advantages. The model is then applied to a small computational domain in the Palermo area, where only some ‘hard’ data given by one rain gauge has been used for calibration and validation, along with ot…
Nonlinear black-box models for short-term forecasting of air temperature in the town of Palermo
2011
Weather data are crucial to correctly design buildings and their heating and cooling systems and to assess their energy performances. In the intensely urbanized towns the effect of climatic parameters is further emphasized by the Urban Heat Island (UHI) phenomenon, known as the increase in the air temperature of urban areas, compared to the one measured in the extra-urban areas. The analysis of the heat island needs detailed local climate data which can be collected only by a dedicated weather monitoring system. The Department of Energy and Environmental Researches of the University of Palermo (Italy) has built up a weather monitoring system that works 24 hours per day and makes data availa…
The impact of urban transformations on the morphology of streets networks
2017
This research takes place in the field of quantitative analysis of historical streets networks.During the last decades, many studies have used network analysis or space syntax approachin a diachronic perspective, either to observe the interdependence between networkconfigurations and land-use, or to explore the link between network configurations and knownurban phenomena, such as densification, dispersal or expansion. These researches often focuson one single transformation rather than on the long time evolution of networks. In this work,we will explore the evolution of the street network of Paris, between 1300 and 1871, and linkthis evolution to all the transformations that occurred in the…
