AbstractIn this paper we develop an augmented Lagrangian method to determine local optimal solutions of the reduced‐ and fixed‐order H∞ synthesis problems. We cast these synthesis problems as optimization programs with a linear cost subject to linear matrix inequality (LMI) constraints along with nonlinear equality constraints representing a matrix inversion condition. The special feature of our algorithm is that only equality constraints are included in the augmented Lagrangian, while LMI constraints are kept explicitly in order to exploit currently available semi definite programming (SDP) codes. The step computation in the tangent problem is based on a Gauss–Newton model, and a specific line search and a first‐order Lagrange multiplier update rule are used to enhance efficiency. A number of computational results are reported and underline the strong practical performance of the algorithm. Copyright © 2003 John Wiley & Sons, Ltd.

This paper presents theoretical, simulation, and experimental study of the brushless doubly fed twin stator induction generator (BDFTSIG) dynamics under vector control based on the orientation on the power machine stator flux. A complex transfer function is derived which links the control current and power winding current space vectors in the field coordinates. Based on this result, the transient response of the BDFTSIG to step changes in the control current is examined theoretically. The oscillatory transients are explained in detail and linked to control flux transients triggered whenever operation point of the generator is changed. Furthermore, BDFTSIG operation with closed loop control of the power machine active and reactive powers is examined theoretically and experimentally. It is shown that in the closed loop operation, the system damping may be reduced so that the PI controller gains must be properly selected to achieve a good transient response.

A new treatment of second-order self-similarity and asymptotic self-similarity for stationary discrete time series is given, based on the fixed points of a renormalisation operator with normalisation factors which are not assumed to be power laws. A complete classification of fixed points is provided, consisting of the fractional noise and one other class. A convenient variance time function approach to process characterisation is used to exhibit large explicit families of processes asymptotic to particular fixed points. A natural, general definition of discrete long-range dependence is provided and contrasted with common alternatives. The closely related discrete form of regular variation is defined, its main properties given, and its connection to discrete self-similarity explained. Folkloric results on long-range dependence are proved or disproved rigorously.

This paper presents a methodological approach to design dynamic output feedback sliding-mode control for a class of uncertain dynamical systems. The control action consists of the equivalent control and robust control components. The design of the equivalent control and the sliding function are based on the pole-placement technique. Linear functional observers are developed to implement the sliding function and the equivalent control. Stability of the resulting system under the proposed control scheme is guaranteed. A numerical example is given to demonstrate its efficacy.

This paper presents the tuning of the structure and parameters of a neural network using an improved genetic algorithm (GA). It will also be shown that the improved GA performs better than the standard GA based on some benchmark test functions. A neural network with switches introduced to its links is proposed. By doing this, the proposed neural network can learn both the input-output relationships of an application and the network structure using the improved GA. The number of hidden nodes is chosen manually by increasing it from a small number until the learning performance in terms of fitness value is good enough. Application examples on sunspot forecasting and associative memory are given to show the merits of the improved GA and the proposed neural network.

This paper presents a neural network with a novel neuron model. In this model, the neuron has two activation functions and exhibits a node-to-node relationship in the hidden layer. This neural network provides better performance than a traditional feedforward neural network, and fewer hidden nodes are needed. The parameters of the proposed neural network are tuned by a genetic algorithm with arithmetic crossover and nonuniform mutation. Some applications are given to show the merits of the proposed neural network.

Electric load forecasting is, essential to improve the reliability of the ac power line data network and provide optimal load scheduling in an intelligent home system. In this paper, a short-term load forecasting realized by a neural fuzzy network (NFN) and a modified genetic algorithm (GA) is proposed. It can forecast the hourly load accurately with respect to different day types and weather information. By introducing new genetic operators, the modified GA performs better than the traditional GA under some benchmark test functions. The optimal network structure can be found by the modified GA when switches in the links of the network are introduced. The membership functions and the number of rules of the NFN can be obtained automatically. Results for a short-term load forecasting will be given.

This paper introduces Neighbor Aware Adaptive Power flooding, an optimized flooding mechanism used in mobile ad hoc networks (MANETS) that employs several mechanisms (neighbor coverage, power control, neighbor awareness and local optimization) to limit the broadcast storm problem, reduce duplicate packet reception and lower power consumption in both transmission and reception. Upon receiving an optimized broadcast, a relay determines a new set of possible relays (to continue the flood) based upon local neighbor information and the previous optimized broadcast. Additionally, neighboring relays only consider the shared neighbors they are closest to. A relay may perform local optimization (to reduce power consumption and isolate broadcasts) by substituting one high power broadcast with two or more low power broadcasts, thereby introducing additional hops, We show that compared to blind flooding and multipoint relaying, NAAP in a static environment greatly reduces the problems associated with the broadcast storm problem, duplicate packet reception and power consumption.

The advances in computer vision, which is a branch of artificial intelligence that focuses on providing computers with the functions typical of human vision is discussed. Computer vision has produced important application in fields such as robotics, biomedicine, industrial automation and satellite observation of Earth. The basic idea behind the use of computer vision in HCIs is that it can be instructed more naturally by human gestures than by using keyboard or mouse. The potentiality of computer vision in improving plant and public safety is attracting increasing attention in security concious community.

AbstractThis paper discusses computational techniques and the way to provide the boundary conditions in order to derive the transfer function of the vocal tract by a three‐dimensional finite element analysis of vocal tract acoustic analysis in a short time. With regard to computational techniques, a solution of the simultaneous equations by successive use of iterative solution, taking the solution at a certain frequency as the initial value, and the use of the finite difference method in part of the analysis domain, are discussed. With regard to the method of providing the boundary condition, the boundary condition at the lip radiating section is discussed. By combining the techniques proposed in this paper, the derivation of the vocal tract transfer function can be accelerated by a factor of as much as 14. © 2003 Wiley Periodicals, Inc.

A method is developed for the automatic detection of the onset of scaling for long-range dependent (LRD) time series and other asymptotically scale-invariant processes. Based on wavelet techniques, it provides the lower cutoff scale for the regression that yields the scaling exponent. The method detects the onset of scaling through the dramatic improvement of a goodness-of-fit statistic taken as a function of this lower cutoff scale. It relies on qualitative features of the goodness-of-fit statistic and on features of the wavelet analysis. The method is easy to implement, appropriate for large data sets and highly robust. It is tested against 34 time series models and found to perform very well. Examples involving telecommunications data are presented.

This paper presents the core loss calculation in soft magnetic composite (SMC) samples and a claw pole permanent magnet machine with SMC stator. By using finite-element analysis of the magnetic field, the total core loss is computed by separating the hysteresis (alternating and rotational, both purely circular and elliptical), eddy current, and anomalous losses in each element when the rotor rotates. The coefficients for each loss component are determined by a loss separation procedure and the experimental data obtained by a single sheet two-dimensional core loss testing system.

This paper presents a new route update strategy for performing proactive route discovery in Mobile Ad hoc Networks (MANETs). In this strategy, the rate at which route updates are sent into the network is controlled by how often a node changes its location by a required distance. We refer to this updating strategy as Minimum Displacement Update Routing (MDUR). We implemented MDUR on top of the Fisheye State Routing (FSR) protocol and investigated its performance by simulation. The simulations where performed in a number of different scenarios, with varied network mobility, density, traffic and boundary. Our results indicate that MDUR has lower levels of control overhead than FSR and achieves higher levels of throughput as the density and the level of traffic in the network is increased.

In this paper, we present a unified framework for semantic shot classification in sports videos. Unlike previous approaches, which focus on clustering by aggregating shots with similar low-level features, the proposed scheme makes use of domain knowledge of a specific sport to perform a top-down video shot classification, including identification of video shot classes for each sport, and supervised learning and classification of the given sports video with low-level and middle-level features extracted from the sports video. It is observed that for each sport we can predefine a small number of semantic shot classes, about 5-10, which covers 90-95% of sports broadcasting video. With the supervised learning method, we can map the low-level features to middle-level semantic video shot attributes such as dominant object motion (a player), camera motion patterns, and court shape, etc. On the basis of the appropriate fusion of those middle-level shot classes, we classify video shots into the predefined video shot classes, each of which has a clear semantic meaning. The proposed method has been tested over 4 types of sports videos: tennis, basketball, Volleyball and soccer. Good classification accuracy of 85-95% has been achieved. With correctly classified sports video shots, further structural and temporal analysis, such as event detection, video skimming, table of content, etc, will be greatly facilitated.

Sports video has been widely studied due to its tremendous commercial potentials. Despite encouraging results from various specific sports games, it is almost impossible to extend a system for a new sports game because they usually employ different sets of low-level features appropriate for the specific games and closely coupled with the use of game specific rules to detect events or highlights. There is a lack of internal representation and structure to be generic and applicable for many different sports. In this paper, we present a generic mid-level representation framework for semantic sports video analysis. The mid-level representation layer is introduced between the low-level audio-visual processing and high-level semantic analysis. It allows us to separate sports specific knowledge and rules from the low-level and mid-level feature extraction. This makes sports video analysis more efficient, effective, and less ad-hoc for various types of sports. To achieve robustness of the low-level feature analysis, a non-parametric clustering, mean shift procedure, has been successfully applied to both color and motion analysis. The proposed framework has been tested for five field-ball type sports covering duration of about 8 hours. Experiments have shown its robust performance in semantic analysis and event detection. We believe that the proposed mid-level representation framework can be used for event detection, highlight extraction, summarization and personalization of many types of sports video.

Color is very useful in locating and recognizing objects that occur in artificial environments. The color histogram has shown its efficiency and advantages as a general tool for various applications, such as content-based image retrieval and video browsing, object indexing and location, and video segmentation. However, due to the lack of any spatial and context information, the histogram is not robust and effective for color characterization (e.g. dominant color) in large video databases. In this paper, we propose a nonparametric color characterization model using mean shift procedure, with an emphasis on spatio-temporal consistency. Experimental results suggest that the color characterization model is much more effective for video indexing and browsing, particularly in the domain of structured video (e.g. sports video).

In this paper, a parallel and distributed algorithm on Spiral Architecture for edge- detection is proposed. The proposed algorithm is based on Master-Slave model. The master node uniformly separates an image using a Spiral Multiplication and sends each slave node a sub-image. Each slave node performs edge detection on the sub-image based on the gradient of image brightness function. Image noise is suppressed by a convolution with Gaussian kerne! before edge points are detected. The gradient consists of three components in three diagonal directions. This detection scheme guarantees a well-balancing load among the slave nodes. Its processing speed is greatly reduced through simultaneous and parallel processes on sub-images. Its accuracy is enhanced by a better approximation of the gradient component.

Spiral Architecture is a new and powerful approach to a general-purpose machine vision system. Earlier research on the Spiral Architecture focused on the properties of undistorted translation, rotation and scaling. The research reported here uses the properties of the pixel address labelling scheme. The property of interest is the physical proximity of the hexagonal pixels with neighbouring addresses. Rectangular systems may, for instance, have vertical physically adjacent pixels but the address distance is the length of a scan line. It is demonstrated that in the Spiral Architecture, unlike the rectangular system, many images have the property that neighbouring pixels have similar intensities thus giving opportunities for better compression.

Active networks present a novel approach to network customization and service deployment. However, they introduce serious security, scalability, and performance compromises at the heart of networks that render their use onto commercial platforms impractical. In this paper, we present a programmable architecture that is capable of deployment onto commercial platforms, while providing service accommodation with secure user separation in an extensible control plane and verified access to a realtime forwarding plane. We envision the architecture as an enabling framework that facilitates the transfer of programmable network technology to the real world.

Internet packet data is analysed to determine the relationship between the arrival process of packets, and of TCP flows of packets. Viewed as point processes, second order properties of the two processes are studied using wavelets, and each is found to have long-range dependence. A new result is given directly linking flow durations to the onset scale of the long range dependence in the flow process. Using this result a mechanism is described whereby the flow level structure could in principle influence the packet level structure, and it is shown and explained why this is not the case currently. The circumstances under which the flow structure could impact on the packet process, and therefore become important for the modeling of the packet level dynamics, are given.

© 2003 IEEE. Starting from the principle of delay constancy requirements of quality of service (QoS) for real-time applications, this paper defines a framework for analysing both the statistical and deterministic end-to-end delay performance in packet switched networks. The framework is based on a novel general queueing model and virtual session server. The paper shows that overall variable packet delay can be decomposed into three separate components; each characterizes and isolates specific factors that constitute the delay components. This separation allows us to derive an expression for the end-to-end delay bound in a packet switched networks of arbitrary topology.

n automated visual surveillance applications, detection of suspicious human behaviors is of great practical importance. However due to random nature of human movements, reliable classification of suspicious human movements can be very difficult. Artificial neural network (ANN) classifiers can perform well however their computational requirements can be very large for real time implementation. In this paper, a data-based modeling neural network such as modified probabilistic neural network (MPNN) is introduced which partitions the decision space nonlinearly in order to achieve reliable classification, however still with acceptable computations. The experiment shows that the compact MPNN attains good classification performance compared to that of other larger conventional neural network based classifiers such as multilayer perceptron (MLP) and self organising map (SOM).

In recent years a number of new devices and systems have become available in the electricity industry that perform continuous, online monitoring of key parameters or indicators of the condition of high voltage plant. 'Online condition monitoring', as it is known, has the potential to generate significant impact in the areas of condition assessment and asset management strategies. However, these benefits will only be realised when analysis can be performed to extract the meaning of the data provided by the devices and systems. This paper describes the steps TransGrid is taking to effectively implement online condition monitoring, with particular focus on some of the analysis that can be performed on online monitoring information.

After a decade of research and development, IP multicast has still not been deployed widely in the global Internet due to many open technical issues: lack of admission control, poorly scaled with large number of groups, and requiring substantial infrastructure modifications. To provide the benefits of IP multicast without requiring direct router support of the presence of a physical broadcast medium, various application level multicast (ALM) models have been attempted. However, there are still several problems with ALM: unnecessary coupling between an application and its multicasting supports, bottleneck problem at network access links and considerable processing power required at the end nodes to support ALM mechanisms. This paper proposes an architecture to address these problems by delegating application-multicasting support mechanisms to smart edge devices associated with the application end nodes. The architecture gives rise to an interesting edge device any-casting technology that lies between the IP-multicasting and the application layer multicasting and enjoys the benefits of both. Furthermore, the architecture may provide sufficient cost-benefit for adoption by service providers. The paper presents initial results obtained from the implementation of a video streaming application over the testbed that implements the proposed architecture.

We consider the problem of reducing a model in a way that preserves a partition of the system states. This is motivated, for instance, in situations where state variables are associated with the topology of a networked system. In earlier work we proposed an LMI method based on block-structured generalized controllability and observability gramians; to make such strategy feasible, coprime factor model reduction was employed. In this paper, we consider the frequency-weighted version of the problem. This is motivated by the usual desire to have model accuracy vary with frequency, but also by the fact that the feasibility of our LMI method can be greatly enhanced through frequency weighting. We show that block-structure can be imposed directly in gramians for frequency weighted problems, and often gives a feasible solution without the need to resort to coprime factors. We also explore the coprime factor version, and give comparisons to other related work in this area.

Bessel beams can be used as optical tweezers, to trap and manipulate small particles, including biological specimens. Here we demonstrate the use of such beams to trap and manipulate particles simultaneously that may reside in completely separate sample chambers, separated by distances that preclude trapping with a Gaussian beam. This also demonstrates another property of the Bessel beam, in that since it is a set of rings it can trap both low and high refractive index particles. The distance behind the particle that the Bessel beam reconstructs is dependent on the properties of the particle, and this may be useful in cell characterisation. We also demonstrate the generation of more complex patterns of nondiffracting light beams, by using interfering Bessel beams. We generate these by using a Mach-Zender interferometer in which each of the arms has a Laguerre-Gaussian beam of differing handedness. © 2003 IEEE.

In this paper, we propose an effective fusion scheme of visual and auditory modalities to detect events in sports video. The proposed scheme is built upon semantic shot classification, where we classify video shots into several major or interesting classes, each of which has clear semantic meanings. Among major shot classes we perform classification of the different auditory signal segments (i.e. silence, hitting ball, applause, commentator speech) with the goal of detecting events with strong semantic meaning. For instance, for tennis video, we have identified five interesting events: serve, reserve, ace, return, and score. Since we have developed a unified framework for semantic shot classification in sports videos and a set of audio mid-level representation with supervised learning methods, the proposed fusion scheme can be easily adapted to a new sports game. We are extending this fusion scheme to three additional typical sports videos: basketball, Volleyball and soccer. Correctly detected sports video events will greatly facilitate further structural and temporal analysis, such as sports video skimming, table of content, etc.

© 2003 IEEE. Semantic sports video analysis has attracted more and more attention recently. In this paper, we present a basketball event detection method by using multiple modalities. Instead of using low-level features, the proposed method is built upon visual and auditory mid-level features i.e. semantic shot classes and audio keywords. Promising event detection results have been achieved. By heuristically mapping semantic shot classes and by aligning audio keywords with semantic shot classes, we have been able to detect nine basketball events. Experimental results have shown our proposed method is effective for basketball event detection.

This paper presents a novel framework called audio keywords to assist event detection in soccer video. Audio keyword is a middle-level representation that can bridge the gap between low-level features and high-level semantics. Audio keywords are created from low-level audio features by using support vector machine learning. The created audio keywords can be used to detect semantic events in soccer video by applying a heuristic mapping. Experiments of audio keywords creation and event detection based on audio keywords have illustrated promising results. According to the experimental results, we believe that audio keyword is an effective representation that is able to achieve more intuitionistic result for event detection in sports video compared with the method of event detection directly based on low-level features.

Current Internet architecture is based on the Best Effort (BE) model, where packets can be dropped indiscriminately in the event of congestion. This architecture attempts to deliver all traffic as soon as possible within the limits of its abilities, but without any guarantees about throughput, delay and packet loss etc. Though such a model works well for certain traditional applications such as FTP, E-mail and less QoS constrained applications, it can be intolerable for newly emerged real-time, multimedia applications such as Internet Telephony, Video-Conferencing and Video on-Demand. This paper is based on the on-going research activities being carried out by various researchers in the area of QoS and proposes a Policy Based Network (PBN) architecture for the Differentiated Services (Diff-serv) Network. Policy Based Networking received much attention recently as the devices within the networks can be implemented with greater control. Our proposed architecture ti based on the functionalities defined within the existing IETF/DMTF Policy architecture, with an objective to achieve QoS through proper Resource management techniques.

Delayed-Multicast is a novel transmission technique to support Video-on-Demand. It introduces buffers within the network to bridge the temporal delays between similar requests thus minimizing the aggregate bandwidth and server load. This paper introduces an improved online algorithm for resource allocation with Delayed-Multicast by utilizing prior knowledge of each clip's popularity. The algorithm is intended to be simple so as to allow for deployment at multiple levels in a distribution network. The result is greater backbone traffic savings and a corresponding reduction in the server load.

© 2003 IEEE. Edge detection is an essential tool in image analysis. It is a process of identifying significant discontinuities in light intensities in order to form an outline of the object of interest. Spiral Architecture provides powerful computational power as a method of image data representation. Gaussian multi-scale theory was employed as the mathematical model for edge detection. The parallel processing algorithm was implemented in the form of a master-slave model. Spiral Architecture enables an image to be uniformly partitioned and distributed to slave processors after spiral multiplication. Concurrent processing is facilitated by inter-process communication and socket interface programming tools of Linux operating system.

This paper extends a scalable to lossless compression scheme to allow scalability in terms of sampling rate as well as quantization resolution. The scheme presented is an extension of a perceptually scalable scheme that scales to lossless compression, producing smooth objective scalability, in terms of SNR, until lossless compression is achieved. The scheme is built around the Perceptual SPIHT algorithm, which is a modification of the SPIHT algorithm. An analysis of the expected limitations of scaling across sampling rates is given as well as lossless compression results showing the competitive performance of the presented technique.

This paper proposes a technique for scalable to lossless audio compression. The scheme presented is perceptually scalable and also provides for lossless compression. It produces smooth objective scalability, in terms of SegSNR, from lossy to lossless compression. The proposal is built around the Perceptual SPIHT algorithm, which is a modification of the SPIHT algorithm and is introduced in this paper. Both objective and subjective results are reported and demonstrate both perceptual and objective measure scalability. The subjective results indicate that the proposed method performs comparably with the MPEG-4 AAC coder at 16, 32 and 64 kbps, yet also achieves a scalable-to-lossless architecture.

Wideband WI coders incorporating this modification and operating at 4 kbps and 6 kbps are described. Subjective testing of these coders, shows that WI is a promising approach to low bit rate wideband speech compression.

In this paper, a modified control strategy for permanent magnet synchronous motor by introducing a space vector modulation conception to a direct torque control (DTC) systems was presented in order to minimize the torque and flux linkage ripples and fix the variable switching frequency in the basic DTC system. The simulation results showed that the steady state performance of the proposed DTC was improved dramatically while keeping the dynamic performance almost as same as that of the basic DTC.

Quadrature mirror filter (QMF) bank with multi-criterion constraints such as minimal aliasing and/or minimal error coding is among the most important problems in filter bank design, for solving which linear algebra-based methods are still heuristic and do not always work, especially for large filter length. It is shown in this paper that when filters are of nonlinear phase this problem can be reduced to convex linear matrix inequality (LMI) optimization, which can be very efficiently solved either by the standard LMI solvers or our previously developed solver. The proposed computationally tractable optimization formulations are confirmed by several simulations.

The advantage of IIR filters over FIR ones is that the formers require a much lower order to obtain the desired response specifications. However, the existing deterministic techniques for IIR filter bank design based on heuristic usually lead to too high order IIR filters and thus cannot be practically used. In this paper, we propose new method to solve the low-order IIR filter bank design, which is based on LMI optimization. Our focus is the QMF bank design, although other IIR filter related problems can be treated and solved in similar way.

View description>>

Flux-weakening of permanent magnet motors is commonly introduced above a base speed beyond which constant power is required. It is shown that lower inverter rating is achieved by also flux-weakening at the base speed. The motor should operate with equal currents and equal power factors at the extremes of the constant power range, with the current lagging the voltage at the base speed and leading the voltage at the maximum speed. Though arbitrarily high inverter utilisation is possible with high currents, it is suggested that a good compromise is to set the current advance angle at the base speed equal to the power angle there. For the broad constant power range limit, the resulting inverter rating is reduced by 23% compared to flux-weakening only above the base speed.

Gradient-based edge detection is a straightforward method to identity the edge points in the original grey-level image. It is consistent with the intuition that in the human vision system the edge points always appear where the change of grey-level is greatest within their neighbourhood. In this paper, triple-diagonal gradient-based edge detection is introduced. It is based on the features of Spiral Architecture and computes the gradients in three diagonal directions instead of approximating the gradient in one direction only as the traditional methods do. Essentially, it improves the accuracy for locating edge points. As a result, it does not need any supplementary processing to enhance the edge map.

Edge map is considered as an important entity containing most of object features in an image. Many computer vision systems rely on the use of the boundary line information to perform the object recognition tasks. However, with the exception of images acquired from highly restricted environment, common edge detectors do not guarantee the production of continuous boundaries of objects. In this paper, a local processing based edge-linking algorithm is proposed. We set a criterion involving multiple properties of the pixel to find the best candidate points for edge linking. In addition, this algorithm is implemented on Spiral Architecture.

Uniform image partitioning has been achieved on Spiral Architecture, which plays an important role in parallel image processing on many aspects such as uniform data partitioning, load balancing, zero data exchange between the processing nodes et al. However, when the number of partitions is not the power of seven like 49, each sub-image except one is split into a few fragments which are mixed together. We could not tell which fragments belong to which sub-image. It is an unacceptable flaw to parallel image processing. This paper proposes a method to resolve the problem mentioned above. From the experimental results, it is shown that the proposed method correctly identifies the fragments belonging to the same sub-image and successfully collects them together to be a complete sub-image. Then, these sub-images can be distributed into the different processing nodes for further processing. © Springer-Verlag Berlin Heidelberg 2003.

In this paper, some new results on the capacity of a typical M-ary pulse position modulation (M-PPM) time hopping (TH) Ultra- Wideband (UWB) system are presented. Previous results using a 'pure PPM model' are proven to exaggerate the real capacity of a UWB system. Based on an extended model containing correlator and soft decision decoding, the capacity is evaluated in the single-user case and in the case of a system with asynchronous multiple user interference (MUI) when the inputs are equiprobable. It is found that only when bit- signal-to-noise ratio (bit-SNR) is high enough, larger M leads to higher capacity; and for a specific M, the optimal values of PPM time offset parameter Td, which maximize the capacity, are independent of bit-SNR. The influence of MUI on capacity is detrimental, especially in the case of high bit-SNR.

The measurement of core losses with 3D magnetic fluxes is discussed. In a magnetic material with an alternating (ID) or two dimensional (2D) rotating magnetic field, the magnetic flux is three dimensional due to the rotation of magnetic domains. The understanding and modeling of the magnetization process in a magnetic material is complete only when the 3D magnetic properties are taken into account.
