Background subtraction (BS) is one of the key techniques in video surveillance applications. To cope with the variations occurred in a scene, including illumination change, the background (BG) model should be updated timely to adapt to those changes. Generally, the BG model is updated by a linear moving average scheme, but this will produce “ghost” trails in the evolved BG model since foreground objects may be merged into the BG model during the updating. In this paper, we propose a novel nonlinear BG updating scheme: the updating rate of the BG model is modified by the absolute difference between the current input and the BG model at the previous moment, and this can suppress the artificial “ghost” trails behind the moving objects in the updated BG model. In order to study the effect of the nonlinear BG updating scheme on the detection results and the evolved BG model over time, we integrate it into two representative BS algorithms: the frame difference and the ViBe algorithm. The nonlinear BG updating scheme can not only extend the discrete updating states in the ViBe algorithm to a continuous one, but also implicitly provide a multi-temporal scale for complex scene. We evaluate the proposed nonlinear BG updating scheme on a database which consists of over 60,000 frames in 21 videos representing 4 scenario categories, and the experimental results demonstrate its efficiency.

In the era of increasing connectivity driven by IoT and CPS concepts, wireless networks are gaining importance in industrial applications. One of their obvious benefits is the support of mobile clients. In complex network infrastructures consisting of many access points, roaming becomes an important aspect because many applications rely on realtime communication and therefore need seamless handover between access points. In IEEE 802.11 WLANs, however, the roaming today is mostly reactive, i.e., a connection is kept as long as the quality of the link provides the possibility to transmit data. If the quality decreases too much the connection is lost, and the client must scan the wireless channels and look for a new access point in order to establish a new connection. The scanning procedure typically takes a long time and thus prohibits seamless roaming. This paper investigates a simple, proactive roaming method using the IEEE 802.11k standard to collect information about the wireless environment prior to roaming. Actual handover is then based on an assessment of the signal strength (RSSI). Experimental results show that the proposed method can reduce the handover time by a factor 30.

In this paper, the authors present a trailer lateral position controller for a non-collocated tractor-trailer system, using steering rate instead of steering angle as control input variable to reduce the tracking error when reference path is a curve. Coordinate transformation is defined at each control sample. Linear quadratic regulator (LQR) is used to eliminate lateral position error. The constraints on steering rate, steering angle and angle difference between tractor and trailer are considered. Simulation results show that the system is able to track lines and curves for both forward and backward motion.

Measurement of the fluid movement in a Magnetohydrodynamic system is an important source of information for design micro-mixers and micro-reactors. The importance of Magnetohydrodynamic systems is that they do not involve mechanical elements which require constant maintenance or parts replacement due to wear. This motivates to experiment with the effects of electric intensity and magnetic fields induced in a fluid, by means of the flow speed measurement. In order to obtain such a measurement, we are designing a Machine Vision System to acquire the velocity fields present in a fluid based on Particle Image Velocimetry (PIV). The conventional PIV systems consisting of a strobe light, a CCD camera, and a cylindrical tower-shaped tank containing seed particles where they flow to the surface. This conventional PIV is not functional for our system, in such a way a customized PIV is needed since the fluid to be analyzed is an electrolyte on an electromagnetic stirrer, whose characteristics differ from a conventional PIV system.

The communication between different partners to handle the different tasks during the life cycle of buildings is far from being perfect. Fragmented engineering, lack of data consistency, insufficient system documentation or sensitivity for data sharing are only a few of many problems in this field that have not been efficiently handled through researches as well as in practice. This paper focuses on a deeper analysis of these problems mainly in the planning and engineering phases (they are the basis for all other phases) from both technical and economical point of view. An approach to handle these problems will be presented and thoroughly discussed.

Particle Swarm Optimization (PSO) is a widely used algorithm to solve complex optimization problems with non-linear objective functions. PSO usually requires powerful and expensive computers to achieve reasonable execution times. Sometimes the price or size of the computing system is unacceptable, forcing designers to simplify the objective function or to discard PSO. To overcome this limitation, this paper proposes the implementation of PSO in Field Programmable Systems-on-Chip (FPSoCs). FPSoC devices combine in the same chip powerful processors and reconfigurable logic (FPGA fabric). Experimental results are presented demonstrating that the proposed system achieves a performance similar to that of a desktop computer for a fraction of cost and size. It can be clearly concluded that the proposed system is a good option for running PSO both at design and final application deployment levels.

This paper proposes a new series of brushless and permanent magnet-less synchronous machines. The main synchronous machine (SM) and the exciter machine are embedded in the same machine structure. Thus two different windings are put in the stator and rotor respectively. The exciter machine may be an induction or a synchronous machine but wound with different number of poles to have magnetic decoupling. Thus, these two machines can be independently controlled. However, the rotor winding (i.e. the field or excitation coils of the synchronous machine) is fed from the rotor windings of the exciter machine through a rotating rectifier. The rectifier converts the induced ac voltage/current to dc to feed the field of the SM. Depending on the type of exciter machine, two different types of machines result. This paper shows the performance of such machines. While details of performance in generating mode are considered, motoring operation is also possible. This paper shows some preliminary analytical and simulation results. Proposed machines have good potential and will definitely increase the use of synchronous machines in future.

The advent of Energy Management (EM) and Electric Vehicles (EV) have completely changed the use of batteries. Accurately estimating the remaining power in batteries has become increasingly important. In order to estimate precise battery state of charge (SOC)/state of health (SOH) value, accurate parameter identification is essential when constructing an accurate battery model. Even though we are able to exactly identify battery parameters offline, the precision of online parameter identification usually suffers from measurement noise, which is an unavoidable phenomenon. In this paper we investigate how battery parameter identification is influenced by measurement noise. The selection of a low pass filter is also discussed and a fourth order Butterworth filter is adopted to effectively reject high frequency measurement noise. This algorithm can help with the identification of battery parameter that rejects measurement noise and maintains the accuracy of online battery parameter identification for future online model-based battery SOC/SOH estimation.

To improve the dynamic performance of voice coil motor, a single position loop control method based on active disturbance rejection control is proposed in this paper. The feedback law is sufficiently analyzed and well designed considering both sinusoidal input and step reference input. Moreover, stability analysis is conducted on the basis of a state-space model and Routh-Hurwitz criterion, which is proved to be stable and convergent under proper parameter arrangement. Further, simulation and experimental validation indicate that the proposed control strategy has faster step response and better tracking accuracy compared with traditional three-loop PI controller with only one eighth of settling time and less than half of the tracking error compared to PI controller.
