There is a persistent problem that continues to be a relevant demand for the chemical, oil, food and pharmaceutical industries, the fouling detection in ducts systems. This work shows the early tests to develop a platform for detecting fouling in pipes and analyze specific locations using the impact hammer test based on a wireless sensor network communication. To minimize the costs of maintaining...
In IoT, numerous group of mobile nodes need to be located simultaneously, for instance, robots in industrial environment, military drill and tourism and the like. To address the issue mentioned above, a novel method of group - positioning was proposed, group partition algorithm and RSSI filter algorithm were designed and implemented. The algorithm was verified under the simulation of the group partition...
Microgrids can be controlled to optimize the generation and consumption of energy in a bounded geographical area which, in the global current scenario, facilitates the integration of distributed energy resources to the main grid. Additionally, some ancillary services, such as support of grid instabilities or power quality improvements, can be also obtained modifying the microgrid control scheme. In...
Many industrial application could benefit from the use of wireless sensor networks technology in safety critical context. This paper analyses the existing platforms to determine if they are suitable for a safety related application, analyses the possible modification to fulfill the requirements and propose an architecture that combines costs, performances and reliability.
In process industry, combination forecasting methods have been proposed to be applied to evaluate product quality. In this paper, multivariate statistical combination forecasting models based on individual forecasting methods which contain principal component regression method (PCR), partial least squares regression method (PLSR) and modified partial least squares regression method (MPLSR) are established...
This paper aims at presenting a simple and efficient single target tracking approach, which is suitable for the applications for modern smart glasses. Specifically, a novel set-to-set similarity measurement is proposed, which takes the critical appearance cues, the contextual structure of the points inside the set and the points' coordinate related to the bounding box into consideration jointly. In...
The increasing availability of sensor data leads to new integration problems in Cyber Physical Systems (CPS). In this paper we present an automatable approach to model CPS systems with common Linear, Time-Invariant processes. We show how this approach can be used to model the thermal processes in a room as well as complex measurements like thermal comfort. We demonstrate our approach for a real building...
It is difficult to obtain high-precision thermal geometric parameters of large hot forgings online because of the harsh measurement condition, the high-temperature and large-sized targets. To solve these problems, an online measurement method for thermal geometric parameters of hot forgings based on laser-aided multi-view stereo vision is proposed in this paper. The core content of the method is to...
Binocular vision measurement technology is widely used in large object measurement, such as large hot forging. However, the traditional method cannot satisfy the requirement of the binocular measurement system in the workshop, which is complex and fast-paced processing. Therefore, an improved binocular measurement system for large hot forging calibration method is proposed in this paper. The binocular...
Accurate extraction of solder bumps in radiographs is a key factor in improving device quality. The conventional method, X-ray-energy subtraction, needs detailed research to determine parameters by numerous experiments and rich human experience. The parameters, however, are not published and are thus not considered general-purpose. Two automated methods were implemented with blind-source separation...
in this work described the basic idea of data transferring in the group of robots while they move in area with high density of obstacles for increasing their movement speed by creating and synchronizing an area map that made by each robot separately. This paper provides a brief review of existing robotic swarm projects and definition of problems in robots teamwork, represents pathfinding methods and...
In controlling ball-screw driven stages of machine tools, industrial robots, and welfare robots, they are modelled as two-inertia systems to consider their transmission characteristics such as low rigidity and nonlinearity. To obtain precise position at the load side, the number of devices with load-side encoders is increasing. The precise joint torque control method and the load-side torque control...
A reconfigurable digital polar transmitter (TX) for Sub-GHz applications is presented. Open-loop phase modulator with high resolution phase interpolator (PI) provides high bandwidth modulation in phase path. The interpolation filters are integrated to push away and suppress spectral aliases. The transmitter has been implemented in 65-nm CMOS. The RF/analog/digital co-simulation shows that the transmitter...
Probabilistic modeling of background is extensively used for foreground detection in computer vision. Gaussian Mixture Models (GMM) is famous choice for detecting foreground in video sequences owing to ability of adapting background variation. However, GMM is prone to camouflage effect i.e. foreground object and background having same pixel intensity. This paper proposes foreground detector based...
A new Technical Vision System for target detection using a Laser Scanner and the Dynamic Triangulation measurement method was developed at the engineering institute of UABC, which presents a single-sensor, high-speed and low-cost laser scanning system, to determine 3D spatial coordinates of any object under observation. Previous research has shown the existence of serious disadvantages, when using...
MicroGrids (MGs) include spatially distributed generation (DG) systems and loads that may require operating autonomously in islanded mode. The operation of islanded MGs can benefit from consensus theory and practice, which are the foundations of distributed control. One of the main features of consensus strategies is that they rely on a cooperative scheme where inverters are required to communicate...
Although a diversity of approaches towards Non-Intrusive Load Monitoring (NILM) are now available, complementary studies must be carried out in order to improve load modeling and consequently increase load recognition accuracy. This paper presents a study on active power appliances' modeling when only low-frequency granularities are considered. The approach analyzes the distribution of power changes...
