Abstract:
The designs of active buckets are analyzed. It is revealed that dynamic impact of buckets on the rock mass can be vibrational or impact. The entire bucket, its front wall, or individual vibration impact devices mounted in the front wall can serve as a dynamic actuator. The drive of the active elements can be electromagnetic, hydromechanical, pneumatic or hydraulic. It is noted that the most successful design of the active bucket is the impact teeth built into the bucket with a pneumatic drive. It is concluded that the most productive idea is an active bucket with built-in impact devices and a hydraulic drive.

Abstract:
This paper presents the unscented transform (UT) applied to uncertainty modeling of manufacturing tolerances at the design stage of microwave passive devices. The process combines the UT with electromagnetic simulations and assumes that the numerical sources of error are negligible in comparison to the imperfections due to the manufacturing process. The technique was validated with the simulation, construction, and test of several sets of identical microstrip filters with very good results. Although the combination of UT and electromagnetic simulators was presented for microstrip filters, it can also be used for different types of microwave devices.

Abstract:
"Nanophotonics technology is the study of the confinement of electromagnetic fields on a subwavelength scale and surface plasmons plays a major role in advancing this arising field. They can take various forms, ranging from freely propagating electron density waves along metal surfaces to localized electron oscillations on metal nanoparticles. The interaction between the free electrons' oscillations and electromagnetic waves of light gives the surface plasmons their appealing characteristics. Their ability of light confinement and propagation through subwavelength structures grants the construction of photonic devices with minimum size, hence the characterize and design of plasmonic devices can be resolved using numerical simulation. This review starts with general introduction about Plasmonic photonic crystal fiber. This is followed by a historical background and literature review of Plasmonic PCF. Some types of designs are illustrated. Finally, the applications of Plasmonic PCF are mentioned dependent on the types of design including the circular plasmonic photonic crystal fiber technique.

Abstract:
Sprung translation mechanisms driven by electromagnetic force actuators are often used to produce controllable motions. This paper is concerned with one family of such devices incorporating linear spring mechanisms suitable for short-range, high-precision applications. In these, a permanent magnet is attached to the movable translating stage which is, in turn, surrounded by a solenoid coil attached to a fixed datum. Design considerations are discussed, principally an optimum dimensional design for a uniformly wound circular cylindrical coil. Design models are verified by the construction of a simple device in steel and aluminium which demonstrates an open-loop positional accuracy of better than 0.5 per cent over a displacement range of 100 nm to 50 μm.

Abstract:
The work is devoted to the creation of a modern web-oriented software platform for designing magnetic systems of special devices and electric machines of new generations that are built on the basis of permanent magnets. To solve the problem of increasing the accuracy of the performed calculations it is necessary to develop new mathematical models that take into account the shielding effect of structural elements on physical processes in electromechanical devices. To obtain mathematical expressions for the calculation of strength components of the magnetic field at given points of piecewise homogeneous space, the method of secondary sources is applied. The studied system is of a generalized design of a magnetic suspension built on the basis of the connected permanent magnets that are facing each other. The entire structure is placed in the shielded housing. Since the electromagnetic system of the device contains parts of a complex shape in its design and has non-linear characteristics of the environment, in order to obtain a mathematical model, an approach is suggested that is based on that a task of calculating the magnetic field for a piecewise homogeneous medium can be formulated in the form systems of Fredholm linear integral equations of the second kind. In accordance with the method of secondary sources, the solution to the field calculation problem is divided into two stages: first the distribution of additional sources is found, the effect of which is equivalent to the influence of a heterogeneous environment on physical processes in work zone, and, at the next stage, based on the principle of superposition of fields, the total magnetic field caused by the presence of primary and secondary sources is calculated. Based on the obtained mathematical model, a calculation algorithm was developed and a web-oriented software system for modeling magnetic field characteristics was created. Using the developed software application, numerical experiments were conducted to simulate the magnetic field in the work zone of an electrical device according to the given electrophysical and geometric design parameters. The proposed approach can be used to solve other similar problems when it is necessary to calculate the characteristics of a system containing permanent magnets in the conditions of a piecewise homogeneous environment.

Abstract:
The integrated motor pump-jet (IMP) propulsion system is a form of modern underwater vehicle propulsion that uses a modular design paradigm. The integrated motor propulsor is a compact construction consisting of a permanent magnet (PM) and a pump-jet propulsor, as well as the propulsion and electrical systems. Compactness, great reliability, and low noise are the most significant features of this technology. The primary technology research status and main application configurations of propulsion devices with an integrated motor were examined based on the working principles and attributes of the devices. The theoretical and experimental research on the design, performance analysis, and control of IMPs is discussed, covering electric motors; bearing structures; hydrodynamic design; and hydrodynamic, electromagnetic, and bearing coupling design technology. This research investigates the most recent research goals, progress, and applications of IMPs, which includes their hydrodynamic performance, cavitation, and gap flow. Finally, the future essential technologies of high power, low vibration, water-lubricated bearings, electromagnetic and bearing coupling design, and IMP antipollution and antidamage capacity are summarized.

Abstract:
Efficient and optimal design of radar-based Advanced Driver Assistant Systems (ADAS) needs the evaluation of many different electromagnetic solutions for evaluating the impact of the radome on the electromagnetic wave propagation. Because of the very high frequency at which these devices operate, with the associated extremely small wavelength, very fine meshes are needed to accurately discretize the electromagnetic equations. Thus, the computational cost of each numerical solution for a given choice of the design or operation parameters, is high (CPU time consuming and needing significant computational resources) compromising the efficiency of standard optimization algorithms. In order to alleviate the just referred difficulties the present paper proposes an approach based on the use of reduced order modeling, in particular the construction of a parametric solution by employing a non-intrusive formulation of the Proper Generalized Decomposition, combined with a powerful phase-angle unwrapping strategy for accurately addressing the electric and magnetic fields interpolation, contributing to improve the design, the calibration and the operational use of those systems.

Abstract With the rapid development of modern science and technology, ship design and construction are becoming more and more large-scale, professional and intelligent, and the degree of integration, intelligence and modularization of port and terminal equipment is also getting higher and higher. Smart ships and wisdom The construction of ports has become an important trend in the development of the shipping industry. Although the rope materials of modern ships have been greatly improved, the main mooring method of ships still relies on the traditional operation method of manual mooring [1], which has low operation efficiency, high degree of danger and high risk factor. This article mainly studies the use of electromagnetic technology to realize the automatic berthing and unberthing of ships. The electromagnetic mooring device is controlled by the remote control system to realize the automatic berthing and unberthing operations of the ship, and the height and angle are automatically adjusted according to the tide and loading conditions to realize berthing monitoring.

Abstract:
The article is devoted to the methods and rules of electronic design of radio electronic devices, which provide high stability and electromagnetic compatibility. The author considers how interferences may be caused by the unsuccessful design decisions when constructing discrete-analog channels of information conversion. The paper gives practical recommendations for choosing appropriate element base, grounding and power sources. The urgency of these tasks is caused by the requirements for increasing the speed of semiconductor devices and electronic circuits in general and reducing the amplitude of the working signals of digital devices, as well as by the problems of increasing the impact of interconnections and the assembly of nodes on the stability and speed of electronic devices and systems, by the problems of reducing the production complexity, material and time consumption, and of finding and eliminating the causes of low noise immunity of electronic devices. With the growth of the speed and layout density of the elements, ensuring the immunity of the electromagnetic interaction between different devices and systems becomes the most important task in construing the radio electronic systems in general. When designing any electronic circuit, one should inevitably allow for addi¬tional parasitic parameters of resistive, inductive and capacitive nature, which may unacceptably impair the performance and noise immunity of the actual design, or even lead to complete loss of functionality. Design and installation have a particular effect on the work of super-high-speed (high frequency) circuits and de¬vices – here the provision of system speed, noise immunity and electromagnetic compatibility become the main criteria for the quality of electronic design. The analysis of the special characteristics of the element base and of the experience of designing power sources and grounding, should help the developers of the electronic devices to reduce the noise in the shaped channels of high-speed data processing

Abstract:
This paper aims to reduce the heating of the electromagnetic actuators of a magnetic bearing. The electrical current of the coils was above normal, so the need for a new coil design to reduce heating due to high currents. In this scenario, the proposed methodology allows minimizing copper losses using Particle Swarm Optimization, so that the best result of the design parameters will be used in the construction of the new coil for the actuator. For the development of this work, it was decided to use a computational tool for public use, FEMM (Finite Element Method Magnetics) to simulate the electromagnetic device. In the simulations, the densities of magnetic fluxes in the core and in the air gap are shown, as well as the energies, electromagnetic forces and losses in the copper of the electromagnetic actuator winding. Finally, an optimal model of the actuator is obtained through the use of optimization techniques. Therefore, the results obtained demonstrate that the proposed methodology is configured as an interesting strategy for the purpose of this work.

Abstract:
Microvalves are essential components of the miniaturization of the fluidic systems to control of fluid flow in a variety of applications as diverse as chemical analysis systems, micro-fuel cells, and integrated fluidic channel arrangements for electronic cooling. Using microvalves, these systems offer important advantages: they can operate using small sample volumes and provide rapid response time. This PhD dissertation presents the world first electromagnetically actuated microvalve fabricated on a single wafer with CMOS compatibility. In this dissertation, the design, fabrication, and testing results of two different types of electromagnetic microvalves are presented: the on/off microvalve and the bistable microvalve with latching mechanism. The microvalves operate with power consumption of less than 1.5 W and can control the volume flow rate of DI water, or a 50% diluted methanol solution in the range 1 - 50 µL in. The leaking rate of the on/off microvalve is the order of 30 nL/min. The microvalve demonstrated a response time for latching of 10 ms in water and 0.2 ms in air. This work has resulted in a US patent, application no. 10/699,210.Other inventions that have been developed as a result of this research are bidirectional, and bistable-bidirectional microactuators with latching mechanism, that can be utilized for optical switch, RF relay, micro mirror, nano indenter, or nano printings.

Full text
Abstract:
When faced with a new design problem, Engineers most often tend to rely on their accumulated knowledge of science, mathematics, and appropriate experience to reach suitable solutions. Case-Based Reasoning is a new engineering paradigm that reflects this fact by suggesting solutions to novel problems based on the recall and reuse of specific experiences. Such a paradigm relies on previous successful design solutions that are stored in the form of separate cases in a database.
The aim of this thesis is to develop a process that will provide examples which can be used to set up a database of optimized designs for various electromagnetic devices such as loudspeakers and actuators. Each stored design will represent an optimum solution to a specific set of requirements for an electromagnetic device. These designs will eventually be used by a case-based reasoning system to reach a solution for possible requested future designs. The process will also involve developing a parameterization of a particular class of devices as well as testing optimization processes to be applied to the initial designs in order to ensure that the solutions stored in the case database represent effective and realistic devices which satisfy the requirements. This thesis also presents test results that illustrate how each optimized design conforms to certain requirements set as an input objective.

Abstract:
Numerical analysis of the electromagnetic fields in large, complex structures is very challenging due to the high computational overhead. Recently, it has been shown that a new method called Trefftz-FLAME ( Flexible Local Approximation MEthod) is suitable for problems where there exist a large number of similar structures.
This thesis develops Trefftz-FLAME in two areas. First, a novel 2D Trefftz-FLAME method incorporates the modal analysis and port boundary condition that are essential to an accurate calculation of reflection and transmission coefficients for photonic crystal devices. The new technique outperforms existing methods in both accuracy and computational cost.
The second area pertains to the 3D, vector problem of electromagnetic wave scattering by aggregates of identical dielectric particles. A methodology for the development of local basis functions is introduced, applicable to particles of any shape and composition. Boundary conditions on the surface of the finite FLAME domain are described, capable of representing the incident wave and absorbing the outgoing radiation. A series of problems involving dielectric spheres is solved to validate the new method. Comparison with exact solutions is possible in some cases and shows that the method is able to produce accurate near-field results even when the computational grid spacing is equal to the radius of the spheres.

We present a system architecture and a set of control techniques that allow heterogeneous software design tools to collaborate intelligently and automatically. One of their distinguishing features is the ability to perform concurrent processing. Systems based on this architecture are able to effectively solve large electromagnetic analysis problems, particularly those that involve loose coupling between several areas of physics. The architecture can accept any existing software analysis tool, without requiring any modification or customization of the tool. This characteristic is produced in part by our use of a neutral virtual representation for storing problem data, including geometry and material definitions. We construct a system based on this architecture, using several circuit and finite-element analysis tools, and use it to perform electromagnetic analyses of several different devices. Our results show that our architecture and techniques do allow practical problems to be solved effectively by heterogeneous tools.

Abstract:
In recent years, due to growing environmental awareness regarding global warming, green cars, such as hybrid electric vehicles, have gained a lot of importance. With the decreasing cost of rare earth magnets, brushless permanent magnet motors, such as the Interior Permanent Magnet Motor, have found usage as part of the traction drive system in these types of vehicles. As a design issue, building a motor with a performance curve that suits both city and highway driving has been treated in this thesis as a multi-objective problem; matching specific points of the torque-speed curve to the desired performance output. Conventionally, this has been treated as separate problems or as a combination of several individual problems, but doing so gives little information about the trade-offs involved. As a means of identifying the compromising solutions, we have developed a stochastic optimizer for tackling electromagnetic device optimization and have also demonstrated a new innovative way of studying how different design parameters affect performance.

Abstract:
This thesis presents an automated topological design system for low frequency electromagnetic devices, e.g. an interior permanent magnet motor. The automated design is carried out through a topological shape optimization process: first, the system employs a topological sensitivity analysis to examine the design domain and to determine the optimal topology (distribution of source and materials); second, the system uses a shape optimizer to further improve the design; these two steps are performed alternately until the optimality condition is satisfied. The robustness of a topology with respect to small variations on its geometries is studied and a robustness measure is defined, originally in the thesis, as the worst case performance of an objective function for the topology and shape optimization. Therefore, the idea of robust design can be applied to the conceptual design (topological design) of electrical machines. Other than the application to motor design, the topology optimization algorithm developed in the thesis, was used originally in the non-destructive testing for quickly location and accurately shape reconstruction of cracks.
Cette thèse présente un système automatique de conception topologique pour les dispositifs électromagnétiques à basse fréquence, par exemple, un moteur à aimant permanent intérieur. La conception automatisée est effectuée par un processus d'optimisation topologique de la forme : d'abord, le système emploie une analyse de sensibilité topologique pour examiner le domaine de la conception et déterminer la topologie optimale (répartition des sources et des matériaux); Deuxièmement, le système utilise une optimisation de forme pour améliorer la conception, les deux étapes étant effectuées alternativement jusqu'à ce que la condition d'optimalité est satisfaite. La robustesse de la topologie par rapport à de petites variations est étudiée et une mesure de robustesse est défini, à l'origine dans cette thèse, comme la performance de la fonction objectif, dans le pire des cas, pour l'optimisation topologique de la forme. Le concept de conception robuste peut donc être appliquée à la conception (conception topologique) des machines électriques. Autre que l'application de la conception du moteur, l'algorithme d'optimisation topologique, développé dans la thèse, a été utilisé à l'origine dans le contrôle non destructif pour trouver rapidement les fissures et preciser la forme optimale.

Abstract:
This thesis investigates the design and optimisation of constrained electromagnetic energy harvesters. It provides optimal design guidelines for constrained electromagnetic energy harvesters under harmonic and random vibrations. To find the characteristics of the vibration source, for instance vertical motion of a boat, the spectrum of the excitation amplitude should be obtained. Two Kalman filter based methods are proposed to overcome the difficulties of calculating displacement from measured acceleration. Analytical models describing the dynamics of linear and rotational electromagnetic energy harvesters are developed. These models are used to formulate a set of design rules for constrained linear and rotational energy harvesters subjected to a given sinusoidal excitation. For the sake of comparison and based on the electromechanical coupling coefficient of the systems, the maximum output power and the corresponding efficiency of linear and rotational harvesters are derived in a unified form. It is shown that under certain condition, rotational systems have greater capabilities in transferring energy to the load resistance and hence obtaining higher efficiency than linear systems. Also, the performance of a designed rotational harvester in response to broadband and band-limited random vibrations is evaluated and an optimum design process is presented for maximizing the output power under these conditions. It is furthermore shown that the profile of the spectral density of the measured acceleration signal of a typical boat can be approximated by a Cauchy distribution which is used to calculate the extracted power extracted by the proposed energy harvester in real conditions. In order to increase the operational bandwidth of rotational energy harvesters, subjected to time-varying frequency vibrations, a variable moment of inertia mechanism is proposed to adaptively tune the resonance frequency of harvester to match the excitation frequency. Also, the effects of combining the variable moment of inertia mechanism and adjusting the load resistance to increase the operational bandwidth of the system for constrained and unconstrained applications are studied. Finally, a ball screw based prototype is manufactured and the experimental results of its testing are presented which confirm the validity of the design and the derived dynamic equations of the system.

Abstract:
Design is concerned with the question of how to construct an artifact or system to meet the desired specification and is normally categorized as either routine, non-routine or creative. Up until now, the study of knowledge-based design has concentrated on routine or non-routine design. In order to explore creativity in design, a new computational model based on the combination of case based reasoning (an approach to solving new problems based on the solutions of similar past problems) and soft computing techniques (such as machine learning, data mining and optimization), is proposed in this thesis. The new model is able to deal with the four challenging issues related to creativity: generation of a design prototype from incomplete requirements, judgment and improvement of system performance given a sparse initial case base library, extraction of pivotal features from a given feature space, adaptation of retrieved previous solutions to similar problems for deriving a new innovative solution to a given design task. The core principle underlying this model is that different knowledge from various level cases can be explicitly explored and integrated into a practical design process.In addition, in order to demonstrate the practical significance of our proposed computational model, a design system for electromagnetic devices which is capable of deriving a new design prototype from a real-world device case base with high dimensionality has been developed.
La conception en général s'intéresse à savoir comment construire un objet ou un système à partir d'une spécification et est normalement classée soit comme routine, non-routine ou créative. Jusqu'à présent, l'étude de la conception basée sur la connaissance est largement concentrée sur la conception routine et non routine. Afin d'explorer la classe créative de la conception, un nouveau modèle computationnel basé sur la combinaison de raisonnement par cas en fonction (une approche pour résoudre de nouveaux problèmes avec l'aide d'une base de solution à des problèmes similaires) et des techniques du «soft computing» (tels que l'apprentissage automatique, l'exploration de données et d'optimisation) est proposé dans cette thèse. Ce nouveau modèle est capable de traiter quatre difficultés associées à la conception créative: la génération d'un prototype à partir d'une spécification incomplète, le raisonnement et l'amélioration de la performance d'un système avec un manqué d'exemple dans la bibliothèque de base de cas, l'extraction de caractéristiques clés d'un espace central de caractéristique donnée, l'adaptation de solutions trouvées à des problèmes similaires pour proposer une nouvelle solution innovante pour une tâche de conception donnée. Le principe de base au sein de ce modèle est que la connaissance de différents cas à des différents niveaux peuvent être précisément exploré et intégré dans un processus de conception pratique. En outre, afin de démontrer l'importance pratique de notre modèle computationnel proposé, un système pour la conception des dispositifs électromagnétiques capable de générer un prototype de conception nouveau à partir d'une base de cas réel à haute dimensionnalité a été développé.

Abstract:
Adaptive systems usually implement the entire cycle of measurement and data acquisition, signal conditioning and processing as well as process control. Especially, for the design of adaptive signal processing and control algorithms detailed insight into the interaction between the system components is of crucial importance. System level simulations are a suitable way to gain insight and to support algorithm design and test. However, an adequate mathematical representation of the system behavior is needed to take advantage of this method. In the paper a generic methodology for behavioral modelling is introduced. Important steps of the modelling process are described and illustrated by two examples. For a gyro sensor system the combination of different modeling methods is demonstrated. Network modeling and in particular an approach for the construction of network models for magnetic systems is discussed for an electromagnetic switching device.

Abstract:
Micro-electro-mechanical systems (MEMS) and nanotechnology are a fast developing technology which combines very small mechanical structures with microelectronics circuits. These devices range in scale from nanometers (10−9 m) to several millimeters, and they are fabricated using the established techniques of microelectronics construction. Due to the increasingly large size and opportunities in these fields, it is becoming necessary to offer course work with small systems for students at the undergraduate and graduate level. A course in MEMS/NEMS small systems was taught at the University of Nevada, Reno in the spring of 2002. The course used the text written by Hsu [1] along with supplementary material. Problems and examples of applying fundamental principles from mechanics, electromagnetism, thermodynamics and optics among others to problems in MEMS design, fabrication and actuation were considered. The course is primarily designed to introduce both engineering undergraduate and graduate students to the possibilities of this exciting new engineering field. Also, current MEMS, NEMS, and microfluidic applications, such as sensors, actuators, heat exchangers, and chemical/biological analysis systems, were discussed. The course introduced a broad spectrum of topics related to small system development including basic engineering science for small system design, engineering mechanics, thermofluid engineering, scaling laws, materials for small systems, fabrication technologies, small system design, advanced nano-materials (molecular motors, nanotubes, polymer nanocomposites), standard characterization techniques: SEM, TEM, AFM, and applications (MEMS, NEMS and microfluidics).

Full text
Abstract:
The Mechanistic-Empirical Pavement Design Guide (MEPDG) has been employed for pavement design by the Indiana Department of Transportation (INDOT) since 2009 and has generated efficient pavement designs with a lower cost. It has been demonstrated that the success of MEPDG implementation depends largely on a high level of accuracy associated with the information supplied as design inputs. Vehicular traffic loading is one of the key factors that may cause not only pavement structural failures, such as fatigue cracking and rutting, but also functional surface distresses, including friction and smoothness. In particular, truck load spectra play a critical role in all aspects of the pavement structure design. Inaccurate traffic information will yield an incorrect estimate of pavement thickness, which can either make the pavement fail prematurely in the case of under-designed thickness or increase construction cost in the case of over-designed thickness. The primary objective of this study was to update the traffic design input module, and thus to improve the current INDOT pavement design procedures. Efforts were made to reclassify truck traffic categories to accurately account for the specific axle load spectra on two-lane roads with low truck traffic and interstate routes with very high truck traffic. The traffic input module was updated with the most recent data to better reflect the axle load spectra for pavement design. Vehicle platoons were analyzed to better understand the truck traffic characteristics. The unclassified vehicles by traffic recording devices were examined and analyzed to identify possible causes of the inaccurate data collection. Bus traffic in the Indiana urban areas was investigated to provide additional information for highway engineers with respect to city streets as well as highway sections passing through urban areas. New equivalent single axle load (ESAL) values were determined based on the updated traffic data. In addition, a truck traffic data repository and visualization model and a TABLEAU interactive visualization dashboard model were developed for easy access, view, storage, and analysis of MEPDG related traffic data.
