A study on forecasting electricity production and consumption in smart cities and factories
2019
Abstract The electrical power sector must undergo a thorough metamorphosis to achieve the ambitious targets in greenhouse gas reduction set forth in the Paris Agreement of 2015. Reducing uncertainty about demand and, in case of renewable electricity generation, supply is important for the determination of spot electricity prices. In this work we propose and evaluate a context-based technique to anticipate the electricity production and consumption in buildings. We focus on a household with photovoltaics and energy storage system. We analyze the efficiency of Markov chains, stride predictors and also their combination into a hybrid predictor in modelling the evolution of electricity producti…
<title>Webometrics: Can we measure the Internet?</title>
2004
This paper refers issues connected with webometrics -- science, which allow conducting various researches over model and content of the Internet, especially WWW sites. Webometrics methodology connections with other disciplines and numerous examples of various, sometimes completely different Internet measures were shown. This paper presents the state of the art in webometrics.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
Graduate of Riga Polytechnic Institute, Engineer, Inventor and Athlete Arno Līcis
2019
The article summarizes the career of a graduate of the Faculty of Mechanics (1964) of Riga Polytechnic Institute Arno Līcis. The article reveals and describes his work while being an engineer at the Riga Electromachine Building Factory (RER), at the Latvian Scientific Research Institute of Trauma- tology and Orthopaedics (LSRITO) and in the printing house «Jāņa sēta», as well as being an inventor. It has been discovered that he had promoted orienteering sports and had significant achievements in competitions of various scale, inclu- ding mass competition named «Magnēts» managed by him, which had been taking place since 1969. This is the first research on the life and professional activities…
Fault diagnosis and modeling of the liquids packaging process. A research based on Petri Nets
2008
Searching for solutions to manufacture industries, which every day deal with problems of faults in their process, that generate economics and humans main losses, an algorithm to construct a Petri Nets based model and diagnoser to isolate and fault detection of discrete events systems is presented. This algorithm is developed in a real process of liquids packaging, where we can see that its implementation allows detecting individuals, simultaneous and dependents faults. The process to construct the model and diagnoser is systematic and useful, and it reduces the problems of combinational explosion, which is the main problem present in other investigations. This research has an excellent proj…
Entrepreneurship in the Middle East and North Africa: A Bibliometric Analysis
2018
Bibliometrics is an important field of information science that enables bibliographic material to be studied quantitatively. Using bibliometric techniques, this chapter offers an overview of entrepreneurship research in the Middle East and North Africa. Using the Web of Science and Scopus databases, we identify the most relevant research in this field, classified by the most influential authors and the top papers, journals and countries. The sample includes 657 articles published from 1963 to 2016, from 387 different sources. The findings show that studies addressing this topic have been published mainly in non-JCR-indexed journals. In contrast, it is important to note that the top papers (…
Relevance of Big Data for Business and Management. Exploratory Insights (Part I)
2018
Abstract Over the last few decades Big Data has impetuously penetrated almost every domain of human interest/action and it has (more or less consciously) become a ubiquitous presence of day to day life. The main questions this exploratory paper seeks to address (throughout its two parts) are the following: What is the (actual) impact of Big Data on Business & Management and How can businesses (through their management) leverage the potential of Big Data to their benefit? A gradual, step by step approach (based on literature review and a variety of secondary data) will guide the paper in search for answers to the abovementioned questions: starting with a concise history of the topic Big …
Bias of library preparation for virome characterization in untreated and treated wastewaters
2020
The use of metagenomics for virome characterization and its implementation for wastewater analyses, including wastewater-based epidemiology, has increased in the last years. However, the lack of standardized methods can led to highly different results. The aim of this work was to analyze virome profiles in upstream and downstream wastewater samples collected from four wastewater treatment plants (WWTPs) using two different library preparation kits. Viral particles were enriched from wastewater concentrates using a filtration and nuclease digestion procedure prior to total nucleic acid (NA) extraction. Sequencing was performed using the ScriptSeq v2 RNA-Seq (LS) and the NEBNext Ultra II RNA …
La transparencia en la Unión Europea
2012
Este estudio versa sobre la formación histórica y vigencia del marco jurídico europeo, en materia de transparencia. Se centra en el derecho de la Unión Europea, por constituir un referente básico de los Estados miembros, en cuanto a la influencia en los ordenamientos jurídicos internos de los mismos. El estudio comprende los Tratados y el derecho derivado, junto a otros actos relacionados con la materia que nos ocupa, durante el periodo de vigencia de cada Tratado, con referencias a la jurisprudencia comunitaria. Además, los estudios sobre la Carta de los Derechos Fundamentales de la Unión Europea y los Códigos de Buena Conducta Administrativa, efectuados por separado, a efectos de mayor cl…
On the power and the systematic biases of the detection of chromosomal inversions by paired-end genome sequencing
2013
One of the most used techniques to study structural variation at a genome level is paired-end mapping (PEM). PEM has the advantage of being able to detect balanced events, such as inversions and translocations. However, inversions are still quite difficult to predict reliably, especially from high-throughput sequencing data. We simulated realistic PEM experiments with different combinations of read and library fragment lengths, including sequencing errors and meaningful base-qualities, to quantify and track down the origin of false positives and negatives along sequencing, mapping, and downstream analysis. We show that PEM is very appropriate to detect a wide range of inversions, even with …
Notice of Violation of IEEE Publication Principles: Distributed Multimedia Digital Libraries on Peer-to-Peer Networks
2007
This paper presents an original approach to image sharing in large, distributed digital libraries, in which a user is able to interactively search interesting resources by means of content-based image retrieval techniques. The approach described here addresses the issues arising when the content is managed through a peer-to-peer architecture. In this case, the retrieval facilities are likely to be limited to queries based on unique identifiers or small sets of keywords, which may be quite inadequate, so we propose a novel algorithm for routing user queries that exploits compact representations of multimedia resources shared by each peer in order to dynamically adapt the network topology to …
