One of the most challenging issues for next generation cellular networks is the provision of Quality of Service (QoS) guarantees to the high number of multimedia applications with different Service Level Agreement (SLA). To improve the utilization of network resources and facilitate management and control, source types are organized into different traffic classes. Each traffic class requires different treatment from the network in terms of allocated bandwidth, delay, jitter, and packet loss. Due to this, traffic classification/differentiation is a main issue in network level QoS. Hence it is required to analyze the issues related to the design of AC, service class differentiation, scheduling mechanisms and compensation scheme. This paper proposes a framework for QoS provisioning and also considers how the key requirement of coexistence between fuzzy based admission control, scheduling and compensation technique could be accommodated in a cellular network system with experimental results.

The main purpose of this paper is to analyze the operation and nature of a low-voltage AC microgrid with various distributed energy resources (DERs). First, a 400 V low-voltage AC microgrid integrated with a 30 kW microturbine generator, a 13 kW photovoltaic generation system, a 10 kW fuel cell generation system, and a 10 kVA wind turbine generator was employed as the sample system. Second, a sequential three-phase power flow program was developed by implicit ZBUS Gauss method. The program was tested in the Matlab environment to ensure its accuracy. Finally, system natural and steady-state operations of the proposed microgrid were analyzed and discussed by using the developed three-phase power flow program. The outcomes of this paper are helpful for researchers to realize the operation characteristics of AC low-voltage microgrids.

This paper presents a novel unknown input observer (UIO) design method for fault detection and isolation (FDI) of a class of nonlinear affine systems with disturbance. By using Lie geometry and sum-of-squares (SOS) theory as the main tools, a simple and systematic design procedure is proposed. Compared with the traditional UIO design, the rank constraint is much relaxed. Meanwhile, we show that the threshold can be easily obtained from a L2 gain result using a SOS formulation.

Automobile industry requires 100% inspection of every electronic component used. If a wire bonding device has a failure rate of 1ppm, it would have the consequence of 15 of 1000 cars would fail. In this paper, we propose a method for tracing and inspecting 3D wire loops in a sealed semiconductor device using X-ray CT. 3D primitives are detected in predefined planes with a subpixel transition detection algorithm. Potential wire centroids are then calculated with deformable generalized cylinders employing an adaptive shape constraint to minimize the interferences from beam-hardening artifacts. Tracing of wires are performed in 2D projection space and mappings are done to find 3D correspondences. To test the capability of the software, we scanned semiconductor wirebond devices with a low resolution X-ray CT system and process slices at present of large amount of artifacts. It is shown that wire loops can be detected reliably with sub-voxel accuracy. The processing time for 10 wires is 30 seconds (using a laptop with Intel dual core 1,6G processor).

A fuzzy backstepping controller design for permanent magnet synchronous motor (PMSM) is presented in this paper. In order to gain good dynamics and robustness, the parameters of nonlinear controller based on backstepping technique is adjusted by fuzzy logic control, and the fuzzy logic control is optimized by adaptive weighted particle swarm optimization (PSO). The adaptive weighted PSO is efficient for multi-objective and multi-dimensional problem. The proposed optimal controller is verified by simulation, and the results show that the controller has robust and good dynamic response.

This paper presents a simple continuous-time linear vaccination-based control strategy for a SEIR (susceptible plus infected plus infectious plus removed populations) propagation disease model. The model takes into account the total population amounts as a refrain for the illness transmission since its increase makes more difficult contacts among susceptible and infected. The control objective is the asymptotically tracking of the removed-by-immunity population to the total population while achieving simultaneously that the remaining populations tend asymptotically to zero.

This paper presents time series analysis for short-term Singapore electricity demand forecasting. Two time series models are proposed, namely, the multiplicative decomposition model and the seasonal ARIMA Model. Forecasting errors of both models are computed and compared. Results show that both time series models can accurately predict the short-term Singapore demand and that the Multiplicative decomposition model slightly outperforms the seasonal ARIMA model.

We develop a layered argumentation system (LAS) for efficient implementation of Fuzzy automation controllers. LAS extends a logic based proposal of argumentation with subsumption concept and varying degree of confidences in beliefs. We show that this argumentation system can be used to model Fuzzy automation controllers. The argumentation system is based on a nonmonotonic logic, the computational complexity of which is known to be linear to the size of the knowledge base. LAS theories can also be mapped into RTL-VHDL (Register Transfer Level-VLSI Hardware Description Language) or RTL Verilog for very efficient hardware implementation of Fuzzy automation controllers.

This paper presents a novel multi-level approach for bleeding detection in Wireless Capsule Endoscopy (WCE) images. In the low-level processing, each cell of K×K pixels is characterized by an adaptive color histogram which optimizes the information representation for WCE images. A Neural Network (NN) cell-classifier is trained to classify cells in an image as bleeding or non-bleeding patches. In the intermediate-level processing, a block which covers 3×3 cells is formed. The intermediate-level representation of the block is generated from the low-level classifications of the cells, which captures the spatial local correlations of the cell classifications. Again, a NN block-classifier is trained to classify the blocks as bleeding or non-bleeding ones. In the high-level processing, the low-level cell-based and intermediate-level block-based classifications are fused for final detection. In this way, our approach can combine the low-level features from pixels and intermediate-level features from local regions to achieve robust bleeding detection. Experiments on real WCE videos have shown that the proposed method of multi-level classification is not only accurate in both detection and localization of potential bleedings in WCE images but also robust to complex local noisy features.

This paper describes a 3D shape reconstruction method using vision sensors targeted at domestic robotics applications. We propose a new method to fuse stereo disparity map and Shape from “Silhouette” (SFS). What we mean by silhouette in this paper is different from the existing silhouette definition. The silhouette here is not obtained from back projecting the object contour to the image plane but rather foreground/background stereo segmentation. Therefore, we impose the restraint that objects must be placed on a richly textured background. Furthermore, we use only three views to obtain the SFS. Preliminary results on domestic objects suggests that our method can distinguish objects such as cylinder, box and ball shapes.
