The dense instrumentation of future smart buildings enables the implementation of advanced control techniques which are aimed at the dual objectives of energy efficiency/cost savings and occupant comfort. One of the essential functions and prerequisite consists of robust dynamic occupancy detection and prediction which allows improved estimation of active thermal zones and internal loads, as compared...
In Internet of Things (IoT) environments, there are multiple sensors and devices monitoring different metrics and producing massive amounts of data. Monitoring of metrics can be done at different frequencies. Systems and applications that consume monitoring data typically use constrained IT resources, e.g., constrained network facilities, storage, display, processing/computing power, and energy. Given...
Proactive monitoring of one's health could avoid serious diseases as well as better maintain the individual's well-being. In today's Internet of Things (IoT) world, there has been numerous wearable technological devices to monitor/measure different health attributes. With the increasing number of attributes and wearables, it becomes unclear to individuals which ones they should be using. The aim of...
In dissonance with the limitations of present substation monitoring system, this paper introduced a Zigbee based wireless network system in traditional online monitoring system and the wireless online monitoring system. This system is constituted by a Zigbee sensor network nodes.and a zigbee coordinator node. The sensor terminal nodes are comprised by different type of sensors and Zigbee wireless...
This paper presents an approach to the evaluation of Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (AAL) e-Health platform, supporting the care of people with special needs (elderly or with health problems) thus improving their quality of life. The proposal is initially verified with the Siafu simulator in an AAL scenario where the users health is monitored with information...
In internet of things (IT) environment, a sensor interface device is essential for data collection in wireless sensor network (WSN) system for water quality monitoring (WQM) as the water pollution is a critical issue globally. This paper presents the design of a WSN based reconfigurable smart sensor interface device for WQM system in an IoT environment. The system consists of Field Programmable Gate...
Context awareness plays an important role that is implemented in smart application. It increases the productivity of smart home as well as pervasive and mobile application. For improving the performance of monitoring human activity that leads us to solve the problem and in order to reduce energy use in case the user forgets to turn off the light, or if we have to take time to walk to the installation...
Wireless sensor network (WSN) plays an important role in monitoring applications in many areas. This paper presents a WSN called EN-Nets which is based on a newly designed small-size and low-power sensor node (EN-Node) for monitoring real-time environmental conditions. Detailed design and implementation of the sensor node for sensing and communicating environmental parameters are described. A power...
Because air pollution had a negative influence on the environment and human health, monitoring its quality has become a necessity. The air quality index is measured on different scales using data collected from devices that are sensitive to 3 up to 8 pollutant agents according to the different national standards. As the forth atmospheric gas in order of concentration, carbon dioxide (CO2), is proven...
Healthcare is one of important factors for persons to keep their happiness during daily life. In order to maintaining good health conditions, daily continuous health monitoring is effective to find small symptoms before causing severe conditions. In this study, wearable, healthcare sensor sheets are proposed to monitor health conditions and activity, simultaneously, consisted of a skin temperature...
The introduction of Internet of Things (IoT) and smart cities is widely viewed as a great opportunity that stimulated the modern view of wireless sensor networks (WSNs). Up to this point, WSNs were application-driven systems with well defined challenges and requirements. The idea of IoT and smart cities increased the amount of available data and magnified the hardware and software challenges of sensor...
Self-awareness is the foundation for many of the nowadays desired system characteristics, such as self-optimization and self-adaption. This awareness is rooted in observation and sensory data obtained by the system regarding itself and its environment. Given the important role which data collection plays in creating this awareness, we believe that it merits more attention than it has so far received...
This paper summarizes the work performed by the authors on development of the sensor network for thermal parameters measurements, as well as structure health monitoring in modern buildings. The described work was carried out as a part of a workpackage within the EC FP7 project SESBE.
The paper deals with the development and the performance characterization of model-based health-monitoring algorithms for the detection of faults in an electro-mechanical flight control actuator for unmanned aerial system flight controls. Two real-time executable position-tracking algorithms, based on predictors with different levels of complexity, are developed and compared in terms of false alarms...
Within the context of bilateral cooperation between Turkey and Tunisia, a Project called “Development of Intelligent Control Modules for Nano Satellites” was initiated in May 2015. Due to political changes in both countries the Project could effectively start on May 2016. The project aims at developing nanosatellite based water quality monitoring within the MENA region. Turkish side consists of researchers...
Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be used for fish conservation. The system consists of a floating node, equipped with sensors, that is...
Our homes, offices, and other spaces are expected to evolve into smart spaces served by devices having varying requirements and capabilities. To efficiently control and manage these devices, their controllers needs to be designed using the correct abstraction for the devices. In this paper, we present an abstraction for the devices in smart spaces, and we use this abstraction to present a 5D—deploy,...
Traditionally, distributed computing concentrates on computation understood at the level of information exchange and sets aside human and organizational concerns as largely to be handled in an ad hoc manner. Increasingly, however, distributed applications involve multiple loci of autonomy. Research in multiagent systems (MAS) addresses autonomy by drawing on concepts and techniques from artificial...
Cold chain is a term related to the equipment and processes used to keep the correct temperature, in which the products, such as food, vaccines, blood, tissues, amongst others, should be stable to be preserved. Any change in temperature can cause a damage in the specific properties in products. Because of that, it is mandatory to constantly monitor temperature and log it to offer traceability. Furthermore,...
Thermogravimetry (TG) or Thermogravimetric Analysis (TGA) is a widely used technique to obtain information about thermal stability and composition and to monitor different thermal processes of materials. The TGA analysis is frequently used to monitor the deposition/sublimation and absorption/desorption processes of volatiles compounds in different environments: outgassing rates from degassing in space...
