Anomaly detection is a domain that represents the key for the future of data mining. We will try to present some key anomaly detection methods applicable in the data mining process. Some methods are existing techniques as the DBSCAN algorithm and some have just been presented to the public recently and could be the answer to future anomaly detection development. One example is the filtering-and-refinement...
Intelligent climate systems have the role to offer appropriate climate conditions in a certain environment. One of the most important parameters which have to be monitored and controlled is the temperature. This paper presents a solution a distributed intelligent climate system for indoor locations. Embedded systems connected to a local network sense the temperature and send the data to a server....
Access systems verify and validate accesses made by users to different resources according to some rules. Access systems can be implemented using IT infrastructure. A classical implementation refers to door access in large buildings. Such a system controls and validates the access in the rooms of a building (such as a company, an institution) according to some policies or access rights. This paper...
Smart metering is a modern topic with a rapid and continuous development. Smart metering offers the advantages of software running systems in measuring and managing the building utilities such as: energy, water, gas etc. The advantages of the smart metering concept are: low metering costs, energy efficiency, possibility to use variable pricing schemes, easier detection of the fraud, remote control...
Ad hoc network does not have an infrastructure, all the nodes have the same functionality and they act not only as sender or destination of a message but also as routers. The lack of infrastructure and the equality of the nodes are not always desirable. This paper proposes a layered architecture for ad hoc networks. It consists in a three layers structure. The first layer consists in a server connected...
Wireless sensor networks have become an important field in our daily lives. A particularly important issue is prolonging the network lifetime using energy saving schemes. This article focuses on tuning an energy saving scheme using coverage metrics. We proposed the energy saving scheme in a previous work. It is based mainly on sensors redundancy combined with graph theory. We introduced best obstacle...
This paper proposes a new method for real-time distributed image acquisition through wireless networks of traffic monitoring cameras. The goal is to provide comprehensive image acquisition in the presence of dynamic disturbances, which obstruct the field of view (FOV) of the cameras. The paper presents a collaborative online algorithm, which (upon FOV loss) identifies an optimized set of cameras that...
Wireless sensor networks have gained importance in various domains due to their rapid development in the past years. However, their greatest limitation remains energy. The lifetime of the sensor network depends on the amount of energy consumption that reflects the amount of data processing done locally in the sensor network. Limited energy resource to the sensor becomes an obstacle for its applications...
This paper presents some of the design decisions that had to be taken and solutions that were adopted during the development of a compiler for a subset of Object Pascal programming language. The compiler is part of a project that has the purpose of facilitating the rapid development of Palm OS applications. The paper details the structure and functions of the compiler's components. The final part...
Although there are certain "preferred" languages for real-time system design, such as C, C++, Ada 95, and increasingly Java, many real-time systems are still written in Fortran, assembly language, and even Visual BASIC. The purpose of this article is to synthesize the theoretical basis of real-time distributed systems in order to facilitate the definition and implementation a new programming...
The executive that is presented in this paper is part of a system of programs designed for rapid development and execution of handheld computer applications. The executive has two versions, one that executes applications on a Windows platform, and another that executes applications on a Palm OS platform. The two executives execute virtual object code generated by an Object Pascal compiler that is...
