  2. 1. An Interactive Traction Motors Design and Selection Software

    Author : Hasan El Hinaoui-Hamze; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

    Abstract : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. READ MORE

  4. 2. Performance Aspects of Databases and Virtualized Real-time Applications

    Author : Christine Niyizamwiyitira; Lars Lundberg; Mikael Svahnberg; Richard Chbeir; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SQL and NoSQL database; Bigdata management systems; Structured and non-structured Database Evaluation; Voice-driven web; Multicore performance prediction; Hard real-time Scheduling; Virtual Multiprocessor Scheduling;

    Abstract : Context: High computing system performance depends on the interaction between software and hardware layers in modern computer systems. Two strong trends that effect different layers in computer systems are that single processors are now more or less completely replaced by multiprocessors, which are often organized into clusters, and virtualization of resources.

  5. 3. Indiscernibility and Vagueness in Spatial Information Systems

    Author : Karim Oukbir; KTH; []
    Keywords : indiscernibility; vagueness; rough sets; fuzzy sets; information systems;

    Abstract : We investigate the use of the concept of indiscernibilityand vagueness in spatial information systems. To representindiscernibility and vagueness we use rough sets, respectivelyfuzzy sets. We introduce a theoretical model to supportapproximate queries in information systems and we show howthose queries can be used to perform uncertain classi. READ MORE

  6. 4. Querying Data Providing Web Services

    Author : Manivasakan Sabesan; Tore Risch; Roberto V. Zicari; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; views of web service operations; web service queries; adaptive parallelization; query optimization; Computer science; Datalogi; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Web services are often used for search computing where data is retrieved from servers providing information of different kinds. Such data providing web services return a set of objects for a given set of parameters without any side effects. READ MORE

  7. 5. Querying mediated web services

    Author : Manivasakan Sabesan; Tore Risch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Web services provide a framework for data interchange between applications by incorporating standards such as XMLSchema, WSDL, SOAP, HTTP etc. They define operations to be invoked over a network to perform the actions. These operations are described publicly in a WSDL document with the data types of their argument and result. READ MORE
