Описание: ThisvolumeconstitutestheproceedingsoftheSixthInternationalConferenceon Flexible Query Answering Systems, FQAS 2004, held in Lyon, France, on June 24-26, 2004. The overall theme of the FQAS conferences is innovative query systems aimed at providing easy, ?exible, and intuitive access to information.
This volume contains some lecture notes of the 12th Reasoning Web Summer School (RW 2016), held in Aberdeen, UK, in September 2016.
In 2016, the theme of the school was "Logical Foundation of Knowledge Graph Construction and Query Answering". The notion of knowledge graph has become popular since Google started to use it to improve its search engine in 2012. Inspired by the success of Google, knowledge graphs are gaining momentum in the World Wide Web arena. Recent years have witnessed increasing industrial take-ups by other Internet giants, including Facebook's Open Graph and Microsoft's Satori.
The aim of the lecture note is to provide a logical foundation for constructing and querying knowledge graphs. Our journey starts from the introduction of Knowledge Graph as well as its history, and the construction of knowledge graphs by considering both explicit and implicit author intentions. The book will then cover various topics, including how to revise and reuse ontologies (schema of knowledge graphs) in a safe way, how to combine navigational queries with basic pattern matching queries for knowledge graph, how to setup a environment to do experiments on knowledge graphs, how to deal with inconsistencies and fuzziness in ontologies and knowledge graphs, and how to combine machine learning and machine reasoning for knowledge graphs.

Описание: The electric power industry is undergoing the most profound technical, economic and organisational changes since its inception some one hundred years ago. This paradigm change is the result of the liberalisation process, stipulated by politics andfollowedupbyindustry. Formanyyearstheelectricpowerindustrywasch- acterized by a vertically integrated structure, consisting of power generation, transmission/distributionandtrading. Theliberalisationprocesshasresultedinthe unbundlingofthisorganizationalstructure. Nowgenerationandtradingareorg- ised in separate business entities, subject to competition, while the transm- sion/distribution business remains a natural monopoly. Since the trading of el- tric energy happens on two levels, the physical level and the contractual level, it has to be recognized that these two levels are completely different. However for understanding the electricity market as a network based industry both levels have to be considered and understood. The fundamental properties of electric energy areasfollows: - Electricityalwaysneedsanetworkfortransportationanddistribution. - Electricitycannot be storedin asubstantialamount, hence production andc- sumptionhavetobematchedateachinstantoftime. - The physical transport of electricity has nothing to do with the contracts for tradingwithelectricity The role of the electric network is of prime importance within the electric energy business. Its operation is governed by physical laws. The electric network has a fixed structure consisting of different voltage levels; the higher levels are for transmission purposeswhereasthe lower levelsareused for the distributiontasks. Eachnetworkelementhasafinitecapacity, limitingtheamountofelectricitytobe transported or distributed. As a consequence of the liberalisation process the - eration of the networks has beenpushedcloser towardsitstechnicallimits. Hence thestressonthesystemisconsiderablybiggerthaninthepast. Theefficientuseof all network elements is of prime interest to the network operator because the cost constraints have also become much tighter than in the past.

Описание:
The extended and revised second edition of this successful monograph presents advanced modeling, analysis and control techniques of Flexible AC Transmission Systems (FACTS). The book covers comprehensively a range of power-system control problems: from steady-state voltage and power flow control, to voltage and reactive power control, to voltage stability control, to small signal stability control using FACTS controllers.
In the six years since the first edition of the book has been published research on the FACTS has continued to flourish while renewable energy has developed into a mature and booming global green business. The second edition reflects the new developments in converter configuration, smart grid technologies, super power grid developments worldwide, new approaches for FACTS control design, new controllers for distribution system control, and power electronic controllers in wind generation operation and control. The latest trends of VSC-HVDC with multilevel architecture have been included and four completely new chapters have been added devoted to Multi-Agent Systems for Coordinated Control of FACTS-devices, Power System Stability Control using FACTS with Multiple Operating Points, Control of a Looping Device in a Distribution System, and Power Electronic Control for Wind Generation.
