Novel Energy Efficient Schemes for Wireless Sensor Networks Utilizing Mobile Sensors
2022
Wireless sensor networks (WSNs) facilitate many applications in different fields and are well-known in both academic and industrial areas. The networks mainly include sensors, networking parts and a data processing center to collect data for a variety of purposes. However, the energy consumption problem in the networks is always a critical problem that many researchers are looking for good solutions. In this paper, we propose a data collection method that uses mobile sensors attached with bigger energy storages to collect data from static sensors. In addition, we propose a hybrid energy harvesting scheme to harvest energy from ambient environments to support static sensors to prolong the ne…
Is naturalistic driving research possible with highly instrumented cars? Lessons learnt in three research centres.
2011
This paper provides an overview of the experiences using Highly Instrumented Cars (HICs) in three research Centres across Europe; Spain, the UK and Greece. The data collection capability of each car is described and an overview presented relating to the relationship between the level of instrumentation and the research possible. A discussion then follows which considers the advantages and disadvantages of using HICs for ND research. This includes the obtrusive nature of the data collection equipment, the cost of equipping the vehicles with sophisticated Data Acquisition Systems (DAS) and the challenges for data storage and analysis particularly with respect to video data. It is concluded th…
Municipal waste management in Sicily: practices and challenges.
2006
There are numerous problems yet to be solved in waste management and although efforts towards waste recovery and recycling have been made, landfills are still the most common method used in the EU and many other industrialised countries. Thermal disposal, particularly incineration, is a tested and viable alternative. In 2004, only 11% of the annual waste production of Italy was incinerated. Sicily, with over five million inhabitants, is the second largest region in Italy where waste management is now a critical problem. The use of landfills can no longer be considered a satisfactory environmental solution; therefore, new methods have to be chosen and waste-toenergy plants could provide an a…
Data gathering and mathematical modelling for pitch stabilisation of a high speed catamaran
2011
This paper deals with the data gathering phase for a 21-foot long planing catamaran. The boat experiences a take-off phenomenon at high speed which needs to be countered. An overview of stability problems in high speed hydroplanes is described with possible solutions recommended. A subsequent gathering of data using laser scanning and computational fluid dynamics (CFD) analysis of the boat are described. The paper ends with a look at the initial developments of stabilising systems for the boat.
Product-related information for sustainable use of laundry detergents in Finnish households
2007
Abstract The purpose of this paper is to report on research on how product-related information can guide sustainable product use in the context of laundry detergents. More precisely, the purpose of the study was designed to analyse how the detergent package information and dosing instructions are read, understood and followed in the Finnish households. Data collection methods included interviews in 340 Finnish households in 2004 and 299 households in 2005 with a standardised questionnaire. Results show that the majority of respondents did not know if the washing water is hard or soft, which indeed has a direct effect on dosing amounts. However, package information per se was found to be eas…
An expert system for vineyard management based upon ubiquitous network technologies
2011
Vineyard operations for quality wines production are currently based upon costly and time-consuming manual sampling operations required to assess the maturity phases of grapevines. The ripening process however is significantly influenced by the environmental parameters which nowadays can be effectively monitored by means of ubiquitous computing technologies. Besides the possibility of gathering data, hence, suitable tools are required to support the vineyard management process. The present research concerns the development of an expert system to effectively manage the vineyard operations. The methodology is based on the analysis of the time series of indices related to the maturation phases…
Hybrid moving bed biofilm reactors: a pilot plant experiment.
2008
The growing increment of the urbanization and on the other hand, the even more strict effluent limits imposed by the Water Framework Directive for the receiving water body quality state have lead to a need of upgrading several existing WWTP. With this respect HMBBR systems are an innovative solution since allow to upgrade existing high loaded WWTP without building new tanks. However, some uncertainties in their design, maintenance as well as performance have to be addressed due to their recent acquisition compared with well consolidated technologies such as activated sludge systems. In this light, a data gathering campaign on a HMBBR pilot plant has been performed. The aim was to detect the…
Proposal of geographic information systems methodology for quality control procedures of data obtained in naturalistic driving studies
2015
The primary goal of naturalistic driving studies is to provide a comprehensive observation of the driver's behaviour under real-life conditions by measureing a great number of parameters at high temporal frequencies. Achieving this goal, however, is a complex endeavor that faces many challenges such as the complexity of the vehicle instrumentation during the phase of data collection, and the difficult handling of large data volumes during the phase of data analysis. These drawbacks often cause episodes of data losses. Improving the technical aspects of the collection of naturalistic data is of paramount importance to increase the return of the investment made in it. An aspect to consider is…
Working Environment in the New EU Member State of Lithuania: Examining a ‘Worst Case’ Example
2008
Using recent survey data from Lithuania, it is suggested that post-communist countries such as Lithuania, admittedly a 'worst case' example, have specific legacies of serious health and safety problems. On a range of general health and occupational safety and health indicators, some three years after joining the European Union, Lithuania is currently a poor performer, and on key indicators the poorest in the European Union. Yet, formally, Lithuania has comprehensive health and safety legislation in line with EU requirements. Survey data suggest, however, a work regime of intensification and an absence of a participative working environment in which employees have a 'voice' in the safety man…
Experiencing Urban Mining in an Italian Municipality towards a Circular Economy vision
2017
Abstract Selective waste collection in Italy has undergone significant changes over the last decade, highlighting very different approaches from one region to another. Research results presented in this paper are underlying differences between geographical regions and use them as a model of good practices to improve the less optimized systems. In the last decade, the Trento City Council has established a goal – the optimization of selective municipal solid waste collection – that led to a very low amount of recyclable materials in the residual fraction. More than that, for the first time sanitary textiles have been considered as a separable fraction at the source; for a long time this type …
