Abstract:
The SAFE Interference Diagram is shown to be useful in the design reliability evaluation of shrouded blading, including long-arc shrouding construction. This method provides an alternate method to the widely used Campbell diagram and also brings in more information for easier design evaluation. The SAFE diagram uses the natural frequencies of an entire bladed disk rather than individual blade or packet frequencies. In addition, it compares frequencies, mode shapes, and speed to evaluate whether a resonance occurs. Theoretical arguments are provided for the validity of the SAFE Diagram and its usefulness is shown by practical examples. This method provides an easier means to show why long-arc shrouding works and also when it might not.

Abstract:
The paper gives out the calibration method of the sensitivity and phase to a vector hydrophone; it analysed the data from the lake trial and the sea trial. The results indicate that, in the isotropic noise field, the sound pressure and the velocity are not related, but the signals are completely relevant. When there is no coherent interference, both the average sound intensity device and the diagram of the target orientation estimation can efficiently estimate the target orientation; when there is the interference of a strong line spectrum, the average sound intensity device cannot work properly, but the diagram can still effectively estimate the target position; when the target radiates spectrum, the line spectrum of the target orientation estimation can still have very good performance.

Abstract:
In this article, the contact behavior of a shrink-fitted joint in a rotor assembly at different spin speeds is studied, using the three-dimensional solid finite element approach. A custom frictionless contact model is proposed and extensively tested by means of simulation. The theory for solving pre-stressed damped eigenvalue problem is presented and implemented, and the results are presented in Campbell diagram form. Two sample rotor assemblies are studied. In addition, experimental modal analysis results of a shrink-fitted joint with various interferences are presented and numerically studied. The reduction of the interference of the shrink-fitted joint due to centrifugal forces at high-speed operation as well as the contact status are updated at each rotational speed step. The inclusion of stress-stiffening effect is studied in detail. The comparison of the Campbell diagram results with the results obtained using a commercial finite element software (Ansys) shows a good agreement.

Abstract:
The article investigates the problem of providing high noise immunity radar under the influence of passive and intentional interference. The purpose of radio operation of the radar is to create conditions that would impede the operation of systems and minimize its effectiveness. The main method of radio transmission is still creating (staging) interference. Modern radar systems must solve the tasks in terms of electronic suppression using, including intentional interference and under severe time constraints. It is shown that the most effective way to improve the noise immunity of radar systems designed to operate in multipoint space, including non-stationary, interference is adaptive space-time processing of the received signals, based on the angular selection of targets, due to the formation of zeros in the directional diagram in the direction of interference sources. This problem is solved by determining the accuracy of the direction finding of interference sources and is achieved by the joint operation of the antenna array and multi-channel signal processing devices, namely the separation of interference signals on different receiving channels.

Abstract:
Context. When protecting radar stations from active noise interference acting along the side lobes of the antenna directional pattern, spatial filtering of signals is used, which is realized by using antennas that are spaced apart in space. In this case, the difference in the directions of reception of the useful signal and the interference makes it possible to form the optimal value of the weighting coefficients of the adaptive spatial filters to suppress the interference. However, if the interfering source moves into the main beam region, then the spatial differences between the wanted signal and the interference are reduced. This leads to significant distortion of the main antenna radiation pattern. As a result, the accuracy of measuring the angular coordinates deteriorates, as well as the sensitivity of the radar receiver. The article proposes a structural-parametric method for adapting a spatial filter, which ensures effective operation of the radar when exposed to the active noise interference both from the direction of the side lobes and from the direction of the main beam. Goal. Improving the efficiency of the radar when the active noise interference source is shifted from the direction to the side lobes to the direction of the main beam. Method. The proposed method makes it possible, due to the structural adaptation of the multichannel spatial filter, to exclude the distortion of the main beam of the radiation pattern of the radar antenna and to ensure its operation under conditions of possible interference from the main beam. Structural adaptation of the spatial filter is realized by the current analysis of the weighting coefficients of the compensation blocks. Results. The structural diagram of the multichannel spatial filter by the Gram-Schmidt method with structural-parametric adaptation, as well as the structural diagram of the compensation block, has been improved. As a result of the simulation, the possibility of eliminating distortions of the radiation pattern of the main antenna of the radar in conditions of the possible impact of the active noise interference along the main beam of the radiation pattern of the radar has been confirmed. Conclusions. The scientific novelty of the work consists in the improvement of the signal-processing algorithm at spatial filtering both when exposed to the active noise interference from the direction of the side lobes, and when the interference source is shifted to the direction of the main beam of radar. The practical novelty of the work lies in the development of a structural diagram and a mathematical model of an improved spatial filter with structural-parametric adaptation.

Abstract:
This paper shows the effect of process damping—caused by the interference between the cutter and the previously cut surface—on the stability of drillstrings. The method of including process damping in the calculation of the stability diagram is outlined. Previously published stability diagrams of drillstrings equipped with drag bits showed decreased stability at low cutting speeds, and that the addition of a shock absorber decreased the size of stability pockets. In this paper, we show that the introduction of process damping confirms field observations of increased stability at low speeds. We also show that a properly designed shock absorber produces large stability pockets where drilling is most effective.

Abstract:
Chaotically modulated signals are used in various engineering areas such as communication systems, signal processing applications, automatic control systems. Because chaotically modulated signal sequences are broadband and noise-like signals, they are used to carry binary signals especially in secure communication systems. In this thesis, a target tracking problem under interference at chaotic communication systems is investigated. Simulating the chaotic communication system, noise-like signal sequences are generated to carry binary signals. These signal sequences are affected by Gaussian channel noise and interference while passing through the communication channel. At the receiver side, target tracking is performed using Optimum Decoding Based Smoothing Algorithm. The estimation performances of optimum decoding based smoothing algorithm at one dimensional chaotic systems and nonlinear chaotic algorithm map are presented and compared with the performance of the Extended Kalman Filter application.

Abstract:
La Modulation Spatiale MIMO (Multiple Input Multiple Output) SM-MIMO est apparue pour répondre à la fois aux besoins croissants de forts débits binaires et d’efficacité énergétique des dispositifs connectés pour l’Internet des objets (IoT) et les réseaux sans fil (5G, Wi-Fi, etc...). Elle se caractérise par l’emploi d’un réseau d’émetteurs. Chaque élément du réseau d’émetteurs code pour un symbole particulier. Mais cette solution n’est pas envisageable pour l’implémentation de petits objets connectés. Dans la première partie de la thèse, nous avons développé plusieurs antennes reconfigurables. Pour nos applications, une antenne reconfigurable possède différents diagrammes de rayonnement codant chacun pour un symbole binaire particulier. Les premiers prototypes fabriqués reposent sur une ligne méandre en couplage avec des résonateurs parasites. Pour accroître la compacité de l’antenne, nous avons conçu une antenne à anneaux fendus générant 8 différents diagrammes de rayonnement décorrélés à la fréquence de 2.45GHz. Pour estimer la fiabilité de la transmission radio, nous calculons numériquement et évaluons expérimentalement la probabilité d’erreurs de transmission (BER) en fonction du rapport Signal-sur-Bruit (SNR). Nos antennes présentent des résultats prometteurs dans l’implémentation d’une communication numérique en environnement indoor. Dans une deuxième partie de la thèse, pour transmettre une donnée vers un récepteur, nous avons exploité les ondes électromagnétiques ambiantes comme sources d’opportunité. Cette nouvelle technique de communication numérique repose sur un rétrodiffuseur capable de commuter entre différents états d’impédance et module le champs électrique ambiant. Ces réseaux sont sujets à des interférences. En particulier, on montre que le diagramme d’interférences entre une source d’onde, un rétrodiffuseur et un récepteur dépend fortement de leur localisation dans l’espace. Nous estimons le BER de la communication par rétrodiffusion et démontrons qu’il dépend du contraste de puissance estimé par le récepteur. A la fin du manuscrit, on donne des axes de recherche possibles pour améliorer la sensibilité du récepteur vis-à-vis du rétrodiffuseur et augmenter le débit binaire de cette communication numérique
The Spatial Modulation MIMO (Multiple Input Multiple Output) SM-MIMO has emerged to meet both the growing need for high data rates and energy efficiency of connected devices for the Internet of Things (IoT) and wireless networks (5G , Wi-Fi, etc ...). It is characterized by the use of a network of transmitters. Each element of the transmitter network encodes a particular symbol. But this solution is not conceivable for the implementation of small connected objects. In the first part of the thesis, we have developed several reconfigurable antennas. For our purposes, a reconfigurable antenna has different radiation patterns whose each of them codes for a particular binary data. The first prototypes manufactured are based on a meander line in coupling with parasitic resonators. To increase the antenna’s compactness, we have developed a split-ring antenna generating 8 different decorrelated radiation patterns at the frequency of 2.45GHz. To estimate the reliability of the radio transmission, we numerically compute and experimentally evaluate the probability of errors of transmission (BER) as a function of the Signal-to-Noise Ratio (SNR). Our antennas show promising results in the implementation of a digital communication in indoor environment. In the second part of the thesis, in order to transmit data to a receiver, we have exploited ambient electromagnetic waves as sources of opportunity. This new digital communication technique is based on a backscatter capable of switching between different states of impedence and thus modulating the ambient electric field. These networks are subject to deep fadings. In particular, it is shown that the interference pattern between a wave source, a backscatter and a receiver strongly depends on their location in space. We estimate the BER of backscatter communication and demonstrate that it depends on the power of contrast estimated by the receiver. At the end of the manuscript, possible search axes are given to improve the sensitivity of the receiver towards the backscatter and to increase the data rate of this digital communication

We present a method of the double-sided Feynman diagram for studies of quantum interference phenomena such as electromagnetically induced transparency, interacting dark resonance, electromagnetically induced absorption, and others in more complex schemes. This method not only provides an alternative to predict the phenomena, but also clearly reveals their physical pictures. Complex schemes that several coherent fields form a chain can be efficiently analyzed with the method. In this work, we have derived role of spontaneous coherence transfer in the propagator of a double-sided Feynman diagram, and demonstrated the systematic approach of the diagram to predict several examples of quantum interference phenomena. Our predictions are in agreement with those from the approach of solving the optical Bloch equation of density matrix operator.

HDMI (high-definition multimedia interface) is a digital interface to transfer image and sounds. It is a common output device for the development technology in recent years. However, EMI (Electromagnetic Interference) is an important issue in such high speed transmission and a lot of problems need to be resolved. Some techniques without extra cost for reducing EMI issues deteriorate eye diagram and some techniques increase the cost by placing numerous shielding on metal chassis. In this thesis, we will focus on the research for note book using Intel processer with HDMI output. It provides a few modification parameters to adjust the signal strength in the Basic Input/Output System (BIOS). It is found that, without increasing the cost and changing the layout, the eye diagram and EMI could be compromised by our proposed techniques for adjusting the level output of BIOS as the following: 1. To satisfy the criteria for eye diagram, the level strength can be set as the default value 1000mV0.0dB or reduce to 800mV0.0dB. 2. To satisfy the criteria for EMI, the level strength can be set as 800mV0.0dB or 600mV0.0dB. 3. To satisfy the criteria for both eye diagram and EMI, the level strength must be set as 800mV0.0dB. Finally, compared to the conventional techniques, our proposed techniques can improve both eye diagram and EMI without increasing the cost and changing the layout.

Abstract:
This thesis proposes a CFD strategy for the aerodynamic and aeromechanic design and verification of axial compressor for gas turbine engines characterized by a combined use of steady and unsteady numerical simulations in order to significantly increase the design accuracy keeping industrial design time requirements.In particular, the stall margin prediction and the forced response assessment are the key aspects of this procedure. An unsteady analysis of the whole compressor is capable of predicting a stall margin comparable to the measured one and, at the same time, of evaluating the complete blade forcing spectrum on each row from the unsteady solution. The spatial decomposition theory introduced in this thesis applied to the overall unsteady aerodynamic forcing allows to separate the contributions of the different nodal diameters. The proposed improved use of the Interference Diagram is able to detect additional possible resonances in the operating range of turbomachines trying to avoid many unexpected vibrations during compressor validation tests.

Abstract:
This textbook is designed for use in a standard physics course on optics at the sophomore level. The book is an attempt to reduce the complexity of coverage found in Modem Optics to allow a student with only elementary calculus to learn the principles of optics and the modern Fourier theory of diffraction and imaging. Examples based on real optics engineering problems are contained in each chapter. Topics covered include aberrations with experimental examples, correction of chromatic aberration, explanation of coherence and the use of interference theory to design an antireflection coating, Fourier transform optics and its application to diffraction and imaging, use of gaussian wave theory, and fiber optics will make the text of interest as a textbook in Electrical and bioengineering as well as Physics. Students who take this course should have completed an introductory physics course and math courses through calculus Need for experience with differential equations is avoided and extensive use of vector theory is avoided by using a one dimensional theory of optics as often as possible. Maxwell’s equations are introduced to determine the properties of a light wave and the boundary conditions are introduced to characterize reflection and refraction. Most discussion is limited to reflection. The book provides an introduction to Fourier transforms. Many pictures, figures, diagrams are used to provide readers a good physical insight of Optics. There are some more difficult topics that could be skipped and they are indicated by boundaries in the text.

In this work, the normalized interference pattern produced by a coherence interferometer system was represented as a complex function. The Laplace transform was applied for the transformation. Poles and zeros were determined from this complex function, and then, its pole-zero map and its Bode diagram were proposed. Both graphical representations were implemented numerically. From our numerical results, pole location and zero location depend on the optical path difference (OPD), while the Bode diagram gives us information about the OPD parameter. Based on the results obtained from the graphical representations, the coherence interferometer systems, the low-coherence interferometer systems, the interferometric sensing systems, and the fiber optic sensors can be analyze on the complex s-plane.

Abstract The population size of one species is affected by the population sizes of other species, which may include predators, prey, parasites, mutualists, and competitors. These interactions are usefully modeled by a path diagram, where arrows indicate how the change in one species’ population size would affect that of another species. This chapter focuses on competition, showing how competition between species affects not only population size but also geographical distribution of species, even at continental scales. In many cases, both exploitation (resource reduction) and interference (aggressive interactions) are involved in competition between species. The concept of the niche is introduced, where in the case of exploitation competition species coexist because each can efficiently exploit at least one resource most efficiently. In the case of interference competition, dominant species gain access to abundant resources but cannot persist where resources are less abundant. Alternative models of coexistence beyond niche partitioning are introduced.

"• Lord Bridge felt no doubts about the decision of the Court of Appeal over statute. • Lord Bridge refers to an earlier point in para 15 that it is wise to ‘refrain from interference’ in matters of legitimate judicial difference (see Appendix 1, p 313, para 15). • ‘If I were making the original decision, I should conclude without hesitation that it would not be fair or reasonable to allow the appellants to rely on the contractual limitation of their liability.’ • Appeal dismissed. A quick review of the paragraphs begins to show the patterns of argument delivery. Re-reading the paragraphs looking at the statutory diagrams (Figures 4.16 and 4.17, above) allows the argument to be reviewed whilst looking at the entire provision. The paragraph approach has also allowed the common law issue and the statutory issue to be isolated. Reviewing Figure 4.12, above, dealing with the facts, issues and procedural history enables the appreciation of the differences between the reasoning in the Court of Appeal and the House of Lords, although both courts reached the same decision. It should be possible at this stage to identify the precise rationale behind the court’s view of the common law issue and the statutory issue. In relation to the statutory issue, it should be possible to pinpoint precisely the statutory areas of relevance and how the court dealt with the issue. A summary of this information has been put into diagrammatic form in Figure 4.18, below. As proficiency is developed, it is possible to read carefully and move straight away to a diagrammatic representation, although, ultimately, a brief conventional textual note should be made to supplement the diagram.

Abstract:
We have designed metal-dielectric heat mirrors by using admittance diagram1-2. We find from the admittance diagram that a low loss metal film is necessary in order to have high transmittance for visible light and a high refractive index film is need in order to have high reflectance in IR. We chose silver as the metal and TiO2 as the dielectric.

Abstract:
The direction cosine space representation of angles relates more directly to fundamental physics than the more common θ and ϕ specifications. Consequently, geometrical optics, radiometry, diffraction, and interference can be better unified. Directions and ranges of directions can be displayed with a simple diagram. If (α, β, γ) are the direction cosines, points in an (α, β) coordinate system represent directions and areas show ranges of direction. Many basic results can be obtained trivially with this diagram. For example, it is easily seen that brightness is conserved by refraction at plane surfaces and single-order diffraction by gratings. In addition, many quantities are actually in direction cosine space without this being realized. For example, the pupil function is properly represented in this space, as are computations involving it, for example, the evaluation of the OTF. The fundamental radiometric quantity ∫dΩ cosθ is an area in the cosine space diagram, as is π sin2θ, a radiometric quantity associated with imaging systems. The direction-cosine space diagram also facilitates understanding of multidimensional phase space, which can be represented by a diagram of diagrams involving both position and direction.

Abstract:
Interference diagrams can be used to avoid the potential excitation of a particular mode of vibration for centrifugal compressor impellers, thus reducing the risk of fatigue failures. Such diagrams are an excellent tool to combine information on impeller natural frequencies and mode shapes, excitation sources and operating speed of the machine on the same graph. Once the impeller design has been finalized in terms of aerodynamic performance, structural assessments and therefore geometry, Finite Element Analysis can be used to predict its natural frequencies and mode shapes (i.e. nodal diameters). Results can therefore be shown on a chart, together with the operating speed range of the machine. The need to plot on a single diagram this whole set of data arises from the mathematical evidence to consider the frequency of vibration together with the mode shape and the shape of the exciting force, while analyzing resonances. Typical Campbell diagrams are unable to provide this information at a glance. A common source of excitation for the first impeller of centrifugal compressors is the IGV set. Inlet Guide Vanes produce an exciting frequency that is directly proportional to the number of vanes N, where N represents also the shape of the excitation. The interference diagram can therefore be used: • to design and optimize the IGV for a new machine; • to choose between two different designs; • to evaluate the impact of a new IGV for the impeller of an existing compressor. A case study will be introduced, in order to show the application of interference diagrams to avoid potentially dangerous resonances between an IGV set and the first impeller during the re-design phase for a centrifugal compressor already in operation.

Full text
Abstract:
Transmissive color filters, in the form of gels, plastics and thin-films, are employed in various lighting systems. To reproduce or match a particular color for the end-user, the filter must have nearly identical spectral transmission properties and the same light source. Additional factors affect the appearance of color, but are not covered in this paper. For any light source (e g. equal-energy, 3200K temperature, etc), the properties of color filters can be quantified using a variety of well established methods, such as 1931 Commission Internationale de l’Eclairage (1931 CIE) or L*a*b*. Using the 1931 CIE method, chromaticity coordinate (x,y) can be calculated from tristimulus values. Furthermore, the dominant wavelength and saturation color performance of a filter can be determined graphically from a chromaticity diagram, or by numerical computation.

Full text
Abstract:
Abstract A complex planar mechanism is usually represented by its simplified schematic representation, called the kinematic skeleton, in both synthesis and analysis. Unfortunately, interferences between links may not be evident from the kinematic skeleton. This paper presents a computer aided top-down technique to design the geometry of an interference free mechanism. The method is intended to replace intuitive and trial and error link geometry design techniques. The geometric design of the links of a mechanism is initiated after the kinematic skeleton diagram is created using existing synthesis and analysis techniques. The solution to the interference problem is initialized by placing links into different layers. To ensure a link, called a reference link, does not interfere with other links within its layer, the work space of those links with respect to the reference link is generated. The resulting domain, called a “swept area”, establishes an illegal region whose complement identifies the feasible region to place the geometry of the reference link. The new method is demonstrated with an example.

Abstract:
The structural integrity and reliability of impeller–shaft assembly in a centrifugal air compressor or any turbo machinery is of at most importance for the trouble free operation. It is thus necessary to avoid any excitation that can cause a resonance for the impeller–shaft system. Considering above, a study on the resonance due to excitation from impeller–stator interaction is undertaken. This paper deals with the construction of impeller interference diagram from the nodal diameters predicted from the cyclic symmetric model of a prototype impeller using ABAQUS. The excitations frequencies arising from impeller–diffuser and impeller–scroll tongue interactions are identified and calculated for the given impeller, diffuser and scroll system. These excitation frequencies are validated for a similar impeller through noise testing and concluded as potential excitation to be considered in design. Stress analysis was carried out to study stresses caused due to centrifugal forces & aerodynamic forces. A nonlinear Static analysis was carried out to account for dynamic stiffening due to centrifugal forces, prior to natural frequency extraction. The Campbell and SAFE diagrams are constructed and the interfering frequencies are identified from the plots constructed in a spread sheet. The nodal diameter versus harmonic force matrix is constructed to understand the forces that can excite a particular nodal diameter for both impeller and impeller–diffuser. From this analysis, it was inferred that diffuser pass frequency was exciting the impeller nodal diameter. Further, analysis was performed to evaluate dynamic stress by carrying out harmonic analysis. Study was carried out to shift natural frequencies of impeller without significantly affecting aerodynamic performance. Iteratively disk back face design, disk thickness, blade thickness & blade geometry were modified to shift frequencies. Frequency extraction procedure was automated by developing user defined macro in ABAQUS. After carrying out study and evaluating possible design Iterations, modifying the impeller blade geometry or altering frequency of source excitation by decreasing the number of diffuser blades were two possible solutions. The effect of both is studied in this paper.
