In this paper, we aimed to build the Abnormal Behavior Profiling (ABP) of IoT devices to supplement other studies that focused on the abnormal behavior detection of IoT devices with a high accuracy rate by a wide variety of machine learning algorithms. ABP will integrate all types of abnormal behavior detection and possess a key role for the purpose of IoT security in the future. Our technical motivation...
Meeting peak electricity demand in Qatar has become a major priority as the consumption levels have been increasing dramatically during the last years. The primary source of customer demand is air conditioning which is a necessity during sweltering summer months. Even though, decision-makers have initiated energy efficiency measures, demand response programs which aim to reduce customer demand during...
In the recent years more and more attention has been directed to the study of potential application of ferrite nanoparticles as the humidity sensing materials. In this paper, we reports the humidity sensing characteristics of yttrium orthoferrite (YFeO3) nanoparticles synthesized by a mechanochemical route from mixture of Y2O3 and α-Fe2O3 powders in a planetary ball mill. Structural analysis of ultrafine...
Lamb wave gas sensor has broad industrial application prospects in gas sensing due to its multi-mode characteristic. Lamb wave gas sensor is now still in fundamental academic research period and its performance remains to be determined and verified experimentally. However, there is a lack of test system that can fully meet the test requirements of Lamb wave gas sensor. In this paper, a test system...
Planar coulometric sensors were tested in humidified synthetic air at various gas temperatures. Generated frost point temperature in the gas ranged from −30 °C to −60 °C and were measured by coulometric sensors and in addition by a calibrated dew point hygrometer. The gas temperatures, which were measured by a calibrated Pt100 sensor, were set to −20 °C, 0 °C, 23 °C, 40 °C, 50 °C, and 60 °C during...
For active temperature controlled quartz resonant dew point sensors, the combination of Peltier and quartz crystal resonators (QCR) is a key factor in the design of sensor structures. A structure in which the Peltier and the QCR are surface to surface combined with single-sided cooling has unstable vibration when environmental parameters continuously change. In order to achieve continuous and accurate...
Paper proposes a kind of multiple environmental parameters monitoring system for granary that is based on ZigBee network and takes ARM controller as core. With regard to hardware, monitoring circuits for temperature, humidity, CO2 concentration and grain water content are designed. With regard to control program, fuzzy intelligent algorithm is designed and transplanted to ARM controller. The test...
A wireless monitoring system, which operates autonomously for up to several years, is discussed. Measurement techniques for temperature and humidity, acceleration and strain are reviewed. Data transmission is carried out by RFID and Bluetooth radio interfaces. The operation algorithm of the wireless monitoring system is reported.
This research would be the early stage in saving and managing energy, especially electrical energy in a miniature. The research has been done in the assembly of components, namely temperature, humidity, lighting and electric active power sensors, where they were equipped by 4–20 mA transmitters. These transmitters entered to the four channel analog module of programmable logic controller (PLC). From...
This paper presents the results of using the Least-Squares Support Vector Machines (LS-SVMs) framework for estimating CO2 levels at the Holst Center building in the Netherlands. Within the IoT framework, a Wireless Sensor Network (WSN) consisting of seven sensors is currently deployed at the third floor of the building. Each sensor node provides measures of temperature, relative humidity and CO2 levels,...
In Japan, about 50 thousand heat stroke patients are emergency transported and die more than 0.1% (about 50–100) patients every year[1]. This study describes the development of the system that gives warning with consideration of high temperature and humidity so that operators at construction sites do not get heatstroke. This system does not only measure the temperature and the humidity near an office...
For the implementation of a 6LoWPAN Home Automation Network with sensor nodes, router, border router, home automation server and user interfaces a sensor node was required. An application which includes temperature, humidity and soil moisture measurement is a plant sensor. From such a sensor node platform, simple room temperature or humidity sensor nodes can be derived. The values of the sensor are...
The article deals with justification to choose optimal thermodynamic condiions to generate porous ammonium nitrate in the vortex granulators. Advantages of granules modification are justified by way of humidification and further thermal treatment. The necessity to improve technologies for porous ammonium nitrate generation is shown with aim to form meso- and macropores on the surface of the granule...
The railway market increasingly requires a longer useful life for the vehicles and a reduction of the maintenance operation, as well as the better prediction of possible failures of the various components. In this context, sensible components are the signal connectors used to transmit information along the train both in fixed and in detachable configuration. Therefore, the paper, after a brief analysis...
PoP or (Point of Presence) is a part of the outermost infrastructure of an ISP that is used to connect the ISP to the customer. PoP is a room which contains servers and aic conditioners. The air conditioners are used to make room remains cool and prevent servers from overheat. In most PoP out there, the operator monitors room every month in order to ensure the cool temperature. In this research, a...
Mine cooling and ventilation systems ensure favourable working conditions underground. Mines are hesitant to reduce the Bulk Air Cooler (BAC) water flow as doing so raises safety concerns. Previous studies on this topic compared the measured wet-bulb temperatures to the maximum allowable wet-bulb temperature of 27.5°C. This paper investigates how the temperature of the underground network is affected...
This article presents the design and develop of a weather station for educational purposes, which can be monitored continuously under different kinds of climatological changes and works autonomously to the energy network. The proposal of this design is based mainly on the measurement of temperature, humidity, wind, UV radiation and rain parameters using low cost commercial sensors compatible with...
A USB cable can be triboelectrically charged by rubbing it against a piece of clothing, such as a sweater. If a charged cable is inserted into a connector, an ESD event can upset or damage attached equipment. To investigate charge levels and estimate the resulting voltages on a USB cable, a set of experiments has been performed in a climate chamber under five different environmental conditions. These...
One of the important factors that support the advance of agriculture system is the quality of the soil, which is used as a medium for growing the plant. The soil quality is a fertile soil and able to give a productive harvest. There are several environmental factors which influence the soil conditions, such as temperature, soil humidity, light, pH of the soil, etc. In this paper, we are designing...
With an increase in the number of warehouses, cold storage units and factories in today's industrialized and automated world, the need for monitoring various attributes in such factories has become a thing of great necessity. With advances in technology, and in particular, the various sensors to measure different parameters such as temperature, gases, humidity etc. have become more viable and affordable...
