Environmental Data Processing by Clustering Methods for Energy Forecast and Planning
2011
This paper presents a statistical approach based on the k-means clustering technique to manage environmental sampled data to evaluate and to forecast of the energy deliverable by different renewable sources in a given site. In particular, wind speed and solar irradiance sampled data are studied in association to the energy capability of a wind generator and a photovoltaic (PV) plant, respectively. The proposed method allows the sub-sets of useful data, describing the energy capability of a site, to be extracted from a set of experimental observations belonging the considered site. The data collection is performed in Sicily, in the south of Italy, as case study. As far as the wind generation…
Toward fast and accurate emergency cases detection in BSNs
2020
International audience; In body sensor networks (BSNs), medical sensors capture physiological data from the human body and send them to the coordinator who act as a gateway to health care. The main aim of BSNs is to save peoples' lives. Therefore, fast and correct detection of emergencies while maintaining low-energy consumption of sensors is essential requirement of BSNs. In this study, the authors propose a new adaptive data sampling approach, where the sampling ratio is adapted based on the sensed data variation. The idea is to use the modified version of the cumulative sum (CUSUM) algorithm (modified CUSUM) that they previously proposed for wireless sensor networks to monitor the data v…
Datorzinātne un informācijas tehnoloģijas: Informācijas apstrādes automatizācija
2004
The first volume in the new series " Automation of Information Processing""contains recent results of young researchers, most of them doctoral students at the University of Latvia. Though the topics of the papers are quite different, they are all centered around the problem of providing theory, methodology, development tools and supporting environment for the development of information systems. All the papers in the volume are related to the most up-to-date issues in the respective area.
Wireless Sensor Network Software Design Rules
2014
Bezvadu sensoru tīkli (BST) pēdējā desmitgadē sevi pierādījusi kā daudzsološa pieeja viedā planētas izpētē, piedāvājot risinājumus savvaļas dabas un dzīvnieku novērošanai, drošības sistēmu izstrādei, pacientu veselības stāvokļa kontrolei, industriālajai ražošanai un citām sfērām. Sensoru tīklu savstarpējai savietojamībai un programmatūras pārnesamībai trūkst vienotu standartu un vienotas metodoloģijas. Eksistē ievērojams skaits operētājsistēmu (OS), virtuālo mašīnu, vaicājumu valodu un citu rīku sensoru tīklu programmēšanai. Ir izstrādāta virkne dažādu komunikācijas protokolu. Tomēr praksē sensoru tīklu projektētāji un programmētāji joprojām saskaras ar problēmām jaunu platformu un lietotņu…

The previous chapter contained presentations of several relevant collaboration methods. Section 3.1 indicated that the evolution in e-collaboration was associated with a number of technological breakthroughs.
Energy Consumption/Generation Model: Data collected, architecture conceived and scenarios addressed
2014
The paper provides the data collected, the architecture and the conceived scenarios for the development of an Energy Consumptions/Generations Model. This model is suitable for the modeling, processing, analyzing and forecasting of energy consumption and generation at home, building and neighborhood level. Data are from the Census Returns, Electoral Registers & Council of the real town of Loughborough (U.K.). The architecture conceived describes the real distribution system which supplies the Loughborough geographic area. The scenarios considered take into account both traditional dwellings (equipped with dumb appliances) and new dwellings (equipped with smart networked appliances) © 2014 IE…
Rough Set Theory for Supporting Decision Making on Relevance in Browsing Multilingual Digital Resources
2017
Browsing digital library (DL) collections seems to pose a challenge for a user owning to the number of factors like for instance, operability of the system, interface readability or clarity, and retrieval efficiency directly related to it, or the number of digital items within the user’s domain. However, when it comes to searching for an item in a foreign language to the user, the number of the factors arises even more which translates proportionally to the growing number of clicks aimed to retrieve the target item. Such a procedure usually leads to disheartening the user from browsing the digital collections. Our study into the user’s behavior interacting with multilingual DL system is set…
dSDiVN: A Distributed Software-Defined Networking Architecture for Infrastructure-Less Vehicular Networks
2017
In the last few years, the emerging network architecture paradigm of Software-Defined Networking (SDN), has become one of the most important technology to manage large scale networks such as Vehicular Ad-hoc Networks (VANETs). Recently, several works have shown interest in the use of SDN paradigm in VANETs. SDN brings flexibility, scalability and management facility to current VANETs. However, almost all of proposed Software-Defined VANET (SDVN) architectures are infrastructure-based. This paper will focus on how to enable SDN in infrastructure-less vehicular environments. For this aim, we propose a novel distributed SDN-based architecture for uncovered infrastructure-less vehicular scenari…
Electricity demand management by optimising the use of HVAC and HWS through AMI
2017
The consumption of electricity is increasing with consistent increase in demand of electricity. Advance metering infrastructure (AMI) is a part of energy management system (EMS) that can pro-actively control the consumption of electricity by engaging with utilities for demand management in real-time. The analysis of the electricity consumption pattern of an Australian house is conducted in this study. The investigation reveals that Heat Ventilation Air conditioning (HVAC) and Hot Water System (HWS) consume approximately 50% of the total electricity consumption. Optimised utilization of these two systems efficiently using AMI can help in reduction of electricity consumption. The study also i…
Review of information and communication technologies for smart micro-grid automation
2017
The growing challenges of Smart Micro-Grid can only be met if secure and fast information and communication technology (ICT) solutions are developed. In this paper, some of the ICT techniques are reviewed for smart micro-grid automation. Firstly, an overview of the role of ICT in grid distribution is explained with respect to electricity value chain in power distribution. Further, each domain in the value chain is analyzed with respect to ICT applications in power generation, transmission, distribution and consumption. ICT stands as a prominent driving force to enhance trustworthiness, security, and productivity of the power distribution through information exchange, regulated generation, d…
