Horizons in Computer Science Research. Volume 17 (Horizons in Computer Science)

This compilation opens with a study wherein state of the art publications on Big Data Analytics are analyzed in order to create an updated classification scheme with several orthogonal dimensions of classification. These dimensions include stages of application, challenges, solution origins, specialization of technologies, purpose, ownership, data processing, data types applied and intended user types. The authors propose that we need an effective data extraction method to gather required data and present it in a meaningful form for further analysis. Next generation interactive data analysis with real time responses requires scalable complex data processing methods to generate meaningful insights. Thus, powerful visualization methods should be designed to allow users to generate reports based on various parameters in a comprehensible way. The authors also outline highly modular framework for the generation and realization of multimodal natural communication incorporating embodied conversational agents, male or female. The personification of the machine responses is achieved through automatic generation and visualization of co-verbal behavior, based on the behavior generation engine, and the physical realization via behavior realization engines based on Unity Game engines core. When a designer is confronted with multi-stakeholders scenarios of use in which the needs of one user group may clash with, compete or be orthogonal to others, the responsibility of sorting, prioritising and including user needs in the user interface solely remains within designers domain. As such, this collection proposes that in an integrated technology ecosystem, user interface designers must have the ability to to uncover user needs that may make an impact on peoples digital experience. The following paper analyzes the basic forms of the legal protection of graphical user interfaces in the European Union, describing the basic principles of protecting registered community designs. The authors deal with the copyright protection of graphical user interfaces, highlighting the advantages and disadvantages of such regimes of protection and their possible overlap. The penultimate chapter outlines the need, terminology, features, types, architecture, uses, and security tools available for data warehouse. The importance of security tools for data warehouse is greater than ever before, so the strategies, and economics of security measures are discussed and the types and effectiveness of security measures are evaluated. Lastly, the authors consider the problem of auto speed scaling scheme optimization for elastic cloud computing platforms. It is observed that there is a tradeoff between performance and cost, i.e., the highest performance and the lowest cost cannot be achieved simultaneously. To analyze this, a queueing model to study a vertically scalable cloud platform, i.e., a multiserver system with variable speed, where both the performance and cost can be characterized effectively.
