Selecting the appropriate parameters for an indoor positioning system may be a difficult task due to the large number of parameter combinations. It is more complex in realistic multi-building multi-floor environments, where severe wrong building and floor errors occur but they are not highlighted in the main evaluation metric. Moreover, a selected parameter configuration, that may seem appropriate...
The need to integrate automatic communication systems in daily applications and technology progress has encouraged speech synthesis sector development. Many variety of voice systems synthesis exist but diphones concatenation method appears to be efficient to contribute to speech synthesis of many languages. The first task in any development of speech synthesis system is to prepare the data base used...
The article presents a case study of applying data cleansing methods and segmentation procedures in order to correct and enhance the structure of the domain corpus of fire service. During the study we present our approach and the results in the task of correcting the misspellings, as well as the method of segmenting the corpus into sentences.
Service-oriented architecture (SOA) is realized by independent, standardized, and self-describing units known as services. This architecture has been widely used and verified for automatic, dynamic, and self-configuring distributed systems such as in building automation. This paper presents a building automation system adopting SOA paradigm with devices implemented by device profile for web service...
Cloud computing provides the possibility of a solution to the problems caused by the massive amounts of data. As an open source cloud computing platform, Hadoop has been widely used in the commercial. MapReduce model is one of the important parts of Hadoop, and it can support parallel computing and schedule tasks automatically. Because of these, it can improve the efficiency of the configuration while...
Cloud services allow for hosting applications partially or completely in the Cloud by migrating their components and data. Especially with respect to data migration, a series of functional and non-functional challenges like data confidentiality arise when considering private and public Cloud data stores. In this paper we identify some of these challenges and propose a set of reusable solutions focusing...
SQL Injection (SQLI) is an attack method that is easy to achieve but often leads data leak and malicious control of the system, so anti SQLI is very important for applications using database. This paper proposes an algorithm for detecting SQLI based on statements sequence digest (SSD). Abstract SQL statement, SSD and its calculating method are defined; algorithms for building SSD and detection SQLI...
Modern applications are increasingly dynamic and heterogeneous and their lifecycle is more and more governed by autonomic managers that are also getting more and more complex. The purpose of this paper is to present a service-oriented framework that facilitates the development and management of dynamically extensible autonomic managers. More precisely, we propose an architecture based on the opportunistic...
This paper presents the first attempt at building a complete diphone based text-to-speech system for the Croatian language using the Festival environment. To collect the target diphones we generated 855 nonsense words and recorded their pronunciations. Diphones were labeled both automatically and manually. Modules for textual and linguistic analysis were developed and discussed. A speech quality evaluation...
Improvements in Internet-based database connectivities and interactive interfacing allow for real-time interaction between users. While, Internet-based learning platforms facilitate, in general, exchange of text, image, and movie files, academic education in design-oriented domains needs support in knowledge exchange with respect to design related issues such as 2D drafting and 3D-4D modeling. In...
Within the MACE project, we support simple access to and retrieval of digital learning resources in exploratory architectural education. In order to facilitate the improved access, we introduce a digital representation of real world objects through an extension of the LOM based MACE application profile, named entity recognition and the combination of various databases. Automatically grouping learning...
Main area of interest is in a system enhancement for locating and tracking users of our information system inside the buildings. The developed framework as it is described here joins the concepts of location and user tracking as an extension for a new type of mobile information systems. The experimental framework prototype uses a WiFi network infrastructure to let a mobile device determine its indoor...
