Secure indoor positioning is critical to successful adoption of location-based services in buildings. However, positioning based on off-the-air signal measurements is prone to various security threats. In this paper, we provide an overview of security threats encountered in such indoor positioning systems, and particularly focus on the relay threat. In a relay attack, a malicious entity may gain unauthorized...
There are several modern ICT applications which suffer from what we call overabundance of capabilities, that is the selection and use of systems with excessive capabilities than those required for the efficient execution and operation of applications and services. Embedded systems comprise a modern promising ICT technology which counteracts this fact via an alternative development paradigm, which...
This paper describes the development of a remote laboratory in the area of automatic and robotic engineering. The laboratory is based on an educational platform around a robotic arm that allows emulating a practical laboratory in which engineering students can confirm their theoretical results comparing them with the real paths traced by the robot. Thus, the research work presented in the article...
Heating, ventilation, and air conditioning (HVAC) control is used to effectively reduce energy consumption in a home energy management system (HEMS). For the HVAC control, it is necessary to evaluate the indoor comfort level because the HVAC operation is significantly related to indoor environmental conditions. Although there are some indices for indoor comfort, individuals have different comfort...
The current tendency to embed computational resources on quotidian objects transforms them into smart objects. This is the vision of Internet of things, where many different devices collect and process information from different sources to both control physical processes and interact with human users. Initially wireless sensor networks and Internet of things concepts were used with the same meaning...
This paper describes the development of a multiple ontology workspace management system and its performance assessment. This management system provides users with their own ontology workspace as a repository. It aims to facilitate the storage and manipulation of ontology models for knowledge driven manufacturing execution systems. The system uses Jena TDB API to maintain the file system on the server...
Although home automation (HA) systems in the wired domain are widely accepted by consumers, in today's industry, the mega trend is steering HA systems along a wireless way. Theoretically, wireless solutions are able to provide HA systems with more flexibility and thus reducing engineering costs. In practice, however, deploying wireless HA systems actually requires more costs and efforts due to the...
Cyber-physical systems are an emergent paradigm to design complex, adaptive and smart systems, combining computational applications with physical hardware devices. Multi-agent systems play an important role in such systems to provide flexibility, robustness and adaptation, but their alignment will require the integration of agents with physical devices. This process is usually complex and time consuming...
The NSF EPSCOR funded Solar Nexus Project is a collaborative effort between scientists, engineers, educators, and technicians to increase the amount of renewable solar energy in Nevada while eliminating its adverse effects on the surrounding environment and wildlife, and minimizing water consumption. The project seeks to research multiple areas, including water usage at power plants, the effect of...
