In order to increase the machining accuracy of slow tool servo turning of complex optical surface, the optimal design for tool path was studied. A comprehensive tool path generation strategy was proposed to optimize the tool path for machining complex surfaces. A new algorithm was designed for tool nose radius compensation which had less calculation error. Hermite segment interpolation was analyzed based on integrated multi-axes controller, and a new interpolation method referred to as triangle rotary method was put forward and was compared with the area method and three-point method. The machining simulation indicated that the triangle rotary method was significant in error reduction. The interpolation error of toric surface was reduced to 0.0015 µm from 0.06 µm and sinusoidal array surface’s interpolation error decreases to 0.37 µm from 1.5 µm. Finally, a toric surface was machined using optimum tool path generation method to evaluate the proposed tool path generation method.

The purpose of electrical load management in a manufacturing plant is to change the load profile in order to gain from reduced total system peak load and increased power factor. One of the widely taken approaches is to optimize the schedule of electrical equipment operation hours to take advantage of incentives and favorable pricing offered by utilities. In this paper, we present our work in designing and developing a web based tool for manufacturing plants to find out an optimal operation schedule of equipment so as to reduce energy cost. The tool allows users to configure their load by specifying electrical devices and their various parameters. Then the online system will assess power consumption over a certain time period, as well as peak power demand and power factor of the defined load.

Chemical compatibility of self-lubricating ceramic tool materials, such as Al2O3/TiC/MoS2, Al2O3/TiC/h-BN, Al2O3/TiC/CaF2, were analyzed and calculated, and the results were verified by X-ray diffraction patterns. The optimal volume content of solid lubricant was calculated by the thermal stress theory under specific condition. The results show that under high temperature, there were some reactions in Al2O3/TiC/MoS2 and Al2O3/TiC/h-BN, while there were no reactions in Al2O3/TiC/CaF2. To Al2O3/TiC/CaF2, the optimal volume content of CaF2 is 25.1% under specific condition.

Fiber reinforced plastics are composite materials that offer a lower weight, while still mechanically perform at least as good as conventional materials such as steel. This makes them attractive for the automotive industry since the implementation of them in e.g. a car frame would enable the manufacturers to sell a more fuel efficient vehicle to the customer. The manufacturing of composites is however more energy intense than for steel and the recycling capabilities are limited. This encourages the car designer to regard the product from a macro-perspective, spanning from the extraction of the resources needed to produce the material, to the phase where the product which the material constitutes is disposed. By analyzing such a macro-perspective, the life cycle energy of a product system can be estimated. Since the life cycle energy is correlated to the component design, an optimization problem can be established where the objective function to be minimized is the total life cycle energy. The component design can be expressed in terms of optimization design variables, yielding that the minimum energy is achieved by the optimal design. This methodology is called life cycle energy optimization (LCEO). The aim of this thesis is to apply this method and present a comparison between different materials and recycling strategies for a load carrying frame component provided by Volvo Cars. The materials studied are carbon fiber reinforced plastics (CFRP), glass fiber sheet moulding compound (GF-SMC) and conventional steel. A Python model consisting of five life cycle phases where each phase was described by a function was implemented. Each function uses the component geometry and material properties as an input and gives the energy of the phase as an output. By summing the outputted energies, the life cycle energy is obtained. The distribution of the results is visualized with bar plots. The results show that the least energy demanding option is to manufacture the component in GF-SMC and process the end-of-life product mechanically. If the fiber degradation is taken into account, the most efficient strategy is to manufacture the component in CFRP and recycle it using solvolysis. This thesis shows that the LCEO methodology can be used as a tool for designers to include the recyclability in an early phase of the product development. Future challenges concern the development of industrial recycling of fiber reinforced plastics where the fiber degradation is minimized.
Fiberförstärkta polymerplaster är kompositmaterial som erbjuder en lägre vikt än konventionella material som stål, samtidigt som de bibehåller den mekaniska prestandan. Detta gör dem intressanta för fordonsindustrin då nyttjandet av dem skulle möjliggöra tillverkare att sälja bränsleeffektivare bilar. Tillverkningen av sådana kompositer är dock mer energikrävande än den för stål och deras återvinningsmöjligheter är begränsade. Detta skapar för fordonsformgivaren ett incitament att beakta produkten i ett makroperspektiv som sträcker sig från utvinningen av naturresurserna för att skapa materialet, till slutskedet av produktens avsedda användning. Genom att bestämma hur den ackumulerade energin är fördelad i ett sådant makroperspektiv kan den total livscykelenergin beräknas. Eftersom livscykelenergin är kopplad till komponentens formgivning, kan ett optimeringsproblem med livscykelenergin som målfunktion att minimeras ställas upp. Komponentens formgivning kan uttryckas som optimeringsproblemets designvariabler. Den design som ger den lägsta livscykelenergin blir därmed den optimala formgivningen. Denna metod kallas livscykelenergioptimering (LCEO). Målet med detta examensarbete är att tillämpa denna metod på en lastbärande bilkomponent tillhandahållen av Volvo Cars och genomföra en jämförelseanalys mellan olika material samt återvinningsstrategier. Materialen som undersöks är kolfiberförstärkt härdplastkompist (CFRP), sheet moulding compound med glasfiber (GF-SMC) och konventionellt stål. Den Pythonimplementerade modellen består av fem livscykelfaser där varje fas uttrycks om en funktion med komponentgeomterin samt materialegenskaperna som indata och ger energiåtgången för fasen som utdata. Genom att summera energierna erhålls livscykelenergin och genom att presentera resultaten i ett stapeldiagram kan livscykelenergidistributionen visualiseras. Resultaten visar att det minst energikrävande alternativet är att tillverka komponenten i GF-SMC och återvinna produkten genom mekanisk bearbetning. Om hänsyn tas till fiberslitage blir den optimala lösningen att tillverka komponenten i CFRP och återvinna den genom solvolys. Detta arbete visar att LCEO- metoden, i ett tidigt skede, kan användas som ett verktyg av formgivare för att inkludera hur väl en produkt kan återvinnas. Framtida utmaningar består av att utveckla återvinningen av fiberförstärkta härdplaster industriellt, så att fiberslitaget minimeras.

This thesis focuses on the design and implementation of a software tool able to achieve electricity grid optimal management in a dynamic pricing environment, at the residential level, and from a customer's perspective. The main drivers encouraging a development of energy management at the home level are analyzed, and a system architecture modeling power, thermodynamic and economic subsystems is proposed. The user behavior is also considered. A mathematical formulation of the related energy management optimization problem is proposed based on the linear programming theory. Several cases involving controllable and non-controllable domestic loads as well as renewable energy sources are presented and simulation scenarios illustrate the proposed optimization strategy in each case. The performance of the controller and the changes in energy use are analyzed, and ideas for possible future work are discussed.

Overlooking the important role materials, in relation to light, have in interior design and architecture is not so uncommon. However, materials are not only important for understanding light in architecture, but also in product design since all objects within a space contribute to its visual character and spatial appearance. This study investigates differences in optical properties of a selection of materials often found in Scandinavian domestic environments. It also explores and discusses the main question of how, in the process of designing a luminaire, product and lighting designers could make use of the visual quality differences between the selected materials, and when put in a spatial context how their properties can be used as a tool to create different lighting scenarios. In order to answer the main question, the study applied a practical approach including a small scale and full-scale laboratory, in which the investigation was based on testing and experimenting with light and material and where qualitative and quantitative aspects were observed, measured, and consolidated.

L'imagerie plénoptique est souvent présentée comme une révolution par rapport à l'imagerie standard. En effet, elle apporte plus de contrôle à l'utilisateur sur l'image finale puisque les dimensions spatiales et angulaires du champ de lumière offrent la possibilité de changer le point de vue ou de refaire la mise au point après coup ainsi que de calculer la carte de profondeur de la scène. Cependant, cela complique le travail du concepteur optique du système pour deux raisons. La première est qu'il existe une multitude d'appareils de capture plénoptique différents, chacun avec sa propre spécificité. La deuxième est qu'il n'existe pas de modèle qui relie le design de la caméra à ses propriétés optiques d'acquisition et qui puisse guider le concepteur dans sa tâche. Cette thèse répond à ces observations en proposant un modèle optique du premier ordre pour représenter n'importe quel appareil d'acquisition plénoptique. Ce modèle abstrait une caméra plénoptique par un réseau équivalent de caméras virtuelles existant en espace objet et qui effectue un échantillonnage identique de la scène. Ce modèle est utilisé pour étudier et comparer plusieurs caméras plénoptiques ainsi qu'un microscope plénoptique monté en laboratoire, ce qui révèle des lignes directrices pour la conception de systèmes plénoptiques. Les simulations du modèle sont aussi validées par l'expérimentation avec une caméra et le microscope plénoptique
Light field imaging is often presented as a revolution of standard imaging. Indeed, it does bring more control to the user over the final image as the spatio-angular dimensions of the light field offer the possibility to change the viewpoint and refocus after the shot and compute the scene depth map.However, it complicates the work of the optical designer of the system for two reasons. The first is that there exist a multitude of different light field acquisition devices, each with its own specific design. The second is that there is no model that relates the camera design to its optical properties of acquisition and that would guide the designer in his task. This thesis addresses these observations by proposing a first-order optical model to represent any light field acquisition device. This model abstracts a light field camera as en equivalent array of virtual cameras that exists in object space and that performs the same sampling of the scene. The model is used to study and compare several light field cameras as well as a light field microscope setup which reveals guidelines for the conception of light field optical systems. The simulations of the model are also validated through experimentation with a light field camera and a light field microscope that was constructed in our laboratory

Il mercato dei materiali compositi è in rapida crescita, soprattutto a causa dell'interesse del settore automobilistico nell'utilizzo di materiali leggeri, come le fibre di carbonio, per aumentare il consumo di carburante delle auto ed aumentarne l’autonomia. Uno dei processi di produzione più promettenti è il CRTM in quanto consente di ottenere componenti ad alte prestazioni limitando i costi di investimento. Infatti, il processo richiede una bassa pressione per l'iniezione della resina liquida attraverso le fibre grazie a un gap presente sopra la preforma in fibra di carbonio che consente alla resina di raggiungere facilmente ogni parte dello stampo. Un altro aspetto degno di attenzione è la possibilità di utilizzare nanocariche disperse nella matrice per migliorare le proprietà dei laminati finiti. Queste proprietà comprendono il comportamento meccanico, termico, elettrico e di smorzamento. Metodi per la progettazione di stampi e attrezzature per il CRTM non sono presenti in letteratura. Anche la dispersione di nanocariche nella matrice utilizzata per il CRTM non è stata completamente affrontata nello stato dell'arte e sono ancora presenti alcune incertezze sulla processabilità e sulle proprietà di queste matrici nano-additivate. Gli obiettivi di ricerca potrebbero essere sintetizzati come lo sviluppo di metodi e strumenti per la progettazione di stampi e attrezzature ausiliarie per il CRTM se si utilizzano matrici nanocaricate. Inoltre, è stata analizzata la correlazione tra i parametri di processo e le prestazioni dei prodotti. Questo lavoro di ricerca rappresenterebbe un passo verso l'adozione del processo CRTM su scala industriale per la produzione di componenti CFRP ad alte prestazioni in modo economicamente vantaggioso. I metodi e gli strumenti proposti possono rappresentare il modo per aumentare l'adozione del processo CRTM basato su matrici nano-additivate nel mercato automobilistico. Al fine di verificare la fattibilità e l'affidabilità di tali strumenti sono stati condotti diversi casi di studio per convalidare i metodi di progettazione scelti. I sistemi sviluppati sono stati progettati tenendo conto dei tre vincoli fondamentali dell'ingegneria di processo: tempi di produzione, costi di produzione e prestazioni dei prodotti.
The market of composite materials is rapidly growing, especially due to the interest of the automotive sector in using lightweight materials, such as carbon fibres, to increase the fuel efficiency of the cars. One of the most promising manufacturing processes is the CRTM as it allows to obtain highperformance components containing investment costs. Indeed, the process requires low pressure for the injection of the liquid resin through the fiber thanks to a gap present over the carbon fiber preform that allows the resin to easily reach every part of the mold. Another aspect worth of attention is the possibility of using nanofillers in addition to the matrix in order to improve the properties of the finished laminates. These properties encompass the mechanical, the thermal, the electrical and the damping behaviour. The use of these nanofillers dispersed in the matrix is possible thanks to the low pressure involved in this process. Methods for the design of molds and ancillary equipment for this process are not present in the literature. Also the presence of nanofillers in the matrix used for the CRTM has not been fully addressed in the state of the art and some uncertainties about the processability and the properties of these nano-additivated matrices are still present. The research goals could be synthesized as the development of methods and tools for the design of molds and ancillary equipment for the CRTM if nanoadditivated matrices are used. Moreover, the correlation between process parameters and performances of the products has been analysed. This research work would represent a step towards the adoption of the CRTM process on an industrial scale for producing high performance CFRP components in a cost/time-effective way. The proposed methods and tools can represent the way to increase the adoption of CRTM process based on nano-additivated matrices in the automotive market. In order to verify the feasibility and the reliability of such tools, different case studies have been conducted with the aim of validate the chosen design methods. The developed systems have been designed taking into account the three fundamental constraints of the process engineering: manufacturing time, manufacturing costs and performances of the products.

Nous vivons une époque exaltante où de nouveaux types d'écrans sont rendus possibles, et la communauté scientifique s'emploie à améliorer l'expérience utilisateur. Nous vivons notamment l'émergence d'écrans courbés, volumétriques, autostéréoscopiques, transparents ou même portés sur la tête, avec des capteurs et algorithmes de plus en plus complexes permettant des interactions toujours plus riches.Cette thèse vise à contribuer à la création de ces nouveaux types d'afficheurs. À travers trois projets concrets, nous associons l'optique et l'informatique pour répondre à des problématiques spécifiques, avec l'objectif final de créer un nouveau type d'écran 3D. Chacun de ces projets a mené au développement de prototypes basés sur l'utilisation de picoprojecteurs laser, de caméras, d'éléments optiques et de logiciels dédiés.Dans un premier projet, nous avons étudié les écrans sphériques : ceux-ci sont plus adaptés que les écrans classiques pour visualiser des données sphériques, cependant les solutions existantes sont onéreuses et difficiles à mettre en place. Nous proposons une méthode pour concevoir un écran sphérique tactile à moindre coût en utilisant seulement des optiques commerciales et peu onéreuses ainsi que des éléments créés par impression 3D, dans le but de rendre ces écrans plus accessibles et reproductibles. Notre solution utilise un picoprojecteur laser associé à un système optique permettant de projeter une image nette sur toute la sphère. L'aspect tactile est réalisé par suivi optique de doigts dans l'infrarouge et nous avons développé un logiciel permettant de gérer l'affichage et l'interaction. Nous compensons l'utilisation de matériel peu coûteux par des calibrations et des corrections logicielles.Nous avons ensuite largement étudié la technologie des guides "wedges" (en forme de "cale"), qui sont devenus des éléments essentiels du reste de la thèse. Les guides wedges ont été initialement développés pour des systèmes de projection plats, mais dans ce projet nous les utilisons dans un contexte d'acquisition. La problématique est la suivante : dans certaines configurations, une zone d'intérêt peut être difficile à imager avec une caméra standard à cause du manque d'espace en face de celle-ci. Nous proposons d'utiliser un guide wedge et un film prismatique afin de replier la distance nécessaire. Nous avons étudié et validé différentes applications dans le domaine spécifique de l'archéologie.Les compétences que nous avons développées au cours de ces deux projets nous ont permis d'imaginer et de concevoir un nouvel écran autostéréoscopique transparent. Un tel écran peut être vu comme une vitre permettant d'ajouter au monde réel des information 3D dépendantes du point de vue, et cela sans avoir besoin de porter de lunettes ou de casques. Le principe est d'utiliser un guide wedge avec des picoprojecteurs laser générant chacun un point de vue différent. Les points de vues sont répartis en face de l'écran par un élément optique holographique que nous avons spécialement conçu. Ce nouvel écran ouvre le champ à de nombreuses applications en réalité augmentée
We live exciting times where new types of displays are made possible, and current challenges focus on enhancing user experience. As examples, we witness the emergence of curved, volumetric, head-mounted, autostereoscopic, or transparent displays, among others, with more complex sensors and algorithms that enable sophisticated interactions.This thesis aims at contributing to the creation of such novel displays. In three concrete projects, we combine both optical and software tools to address specific applications with the ultimate goal of designing a three-dimensional display. Each of these projects led to the development of a working prototype based on the use of picoprojectors, cameras, optical elements, and custom software.In a first project, we investigated spherical displays: they are more suitable for visualizing spherical data than regular flat 2D displays, however, existing solutions are costly and difficult to build due to the requirement of tailored optics. We propose a low-cost multitouch spherical display that uses only off-the-shelf, low-cost, and 3D-printed elements to make it more accessible and reproducible. Our solution uses a focus-free projector and an optical system to cover a sphere from the inside, infrared finger tracking for multitouch interaction, and custom software to link both. We leverage the use of low-cost material by software calibrations and corrections.We then extensively studied wedge-shaped light guides, in which we see great potential and that became the center component of the rest of our work. Such light guides were initially devised for flat and compact projection-based displays but in this project we exploit them in a context of acquisition. We seek to image constrained locations that are not easily accessible with regular cameras due to the lack of space in front of the object of interest. Our idea is to fold the imaging distance into a wedge guide thanks to prismatic elements. With our prototype, we validated various applications in the archaeological field.The skills and expertise that we acquired during both projects allowed us to design a new transparent autostereoscopic display. Our solution overcomes some limitations of augmented reality displays allowing a user to see both a direct view of the real world as well as a stereoscopic and view-dependent augmentation without any wearable or tracking. The principle idea is to use a wedge light guide, a holographic optical element, and several projectors, each of them generating a different viewpoint. Our current prototype has five viewpoints, and more can be added. This new display has a wide range of potential applications in the augmented reality field

In view of its inevitable implications at an individual and collective level, in all historic periods hospital building has represented the most advanced level of elaboration of architectural models aimed at the optimal synthesis of form, function and technique. Consequently, the typological and morphological reading of the Ospedale degli Infermi of Faenza, in the wake of a campaign of architectural surveys and archive research, represents an opportunity for verifying the relationship between technical culture and design and building practice through which it is possible to identify the typological and semantic values of the architecture. Designed and constructed by the master builders Raffaele and Giovanbattista Campidori in the middle of the eighteenth century, the various phases in the transformation of the Hospital are analysed down to our own times, positing tools and methods of investigation designed to optimise operations for the rehabilitation and conservation of the most ancient part of the building.

Chapter 2 provides an introduction to SCs as a group. It presents a historical overview of how quotas became an important policy tool for addressing social injustice in India, and notes primary sources on the initial debates about the design of electoral institutions in the early twentieth century. Tracing the debate on electoral quotas between 1905 and 1950, the chapter shows the gradual shift in focus from group representation to group integration. This was reflected in disagreements about the optimal institutional design for combating the caste system: should SC politicians be elected by SC voters only, or by voters from all caste groups? The latter view prevailed, with quotas explicitly designed to integrate SC politicians into mainstream politics by making it necessary for them to appeal to voters from all caste groups.

Stress tests are the most innovative regulatory tool to prevent and fight financial crises. Their use has fundamentally changed the modeling of financial systems, financial risk management in the public and private sector, and the policies designed to prevent and mitigate financial crises. When financial crises hit, stress tests take center stage. Despite their centrality to public policy, the optimal design and use of stress tests remains highly contested. Written by an international team of leading thinkers from academia, the public sector, and the private sector, this handbook comprehensively surveys and evaluates the state of play and charts the innovations that will determine the path ahead. It is a comprehensive and interdisciplinary resource that bridges theory and practice and places financial stress testing in its wider context. This guide is essential reading for researchers, practitioners, and policymakers working on financial risk management and financial regulation.

Constitutions have been a central topic for the economic analysis of law since Buchanan and Tullock (1961) introduced the discipline of constitutional political economy. From the outset economic analysis has been deployed for both positive and normative ends. Their project was normative, but economic analysis provides tools to critique real world constitutions and to analyze their attributes. Optimal design of constitutions in theory is rarely matched in practice, but this is no hindrance to understanding the form, duration, and impact of actual constitutions. This chapter reviews the ends of constitutional design. It offers a positive theory of constitutional bargaining which can be used to inform normative design questions. Whether particular institutions ought to be included in a constitution depends on the extent to which such texts make a difference, which is an empirical question subject to some scrutiny. A review of the empirical literature on constitutional design concludes.

This chapter concludes the book, emphasizing that the authors do not attempt to define an optimal court. However, they argue that high court design influences how judges decide, and therefore we need a better theory of institutional design and improved ability to tease out how and when design matters. The differences across courts are both important and interesting in terms of where they come from and what their implications are. They enable an understanding of what may be necessary to improve high court design in particular countries. Countries cannot move toward better institutions without understanding how design features relate to the factors that underlie how a judge decides and to each other. Too much work has focused on courts in isolation without understanding the broader suite of design options and their implications.

AbstractTraditional analytical methods are approximate and need to be validated when it comes to predict the tensional behavior of thread coupling. Numerical finite element simulations help engineers come up with the optimum design, although the latter depends on the constraints and load conditions of the thread couplings which are often variable during the system functioning. The present work illustrates a new method based on Radial Basis Functions Mesh Morphing formulation to optimize the stress concentration in thread couplings which is subject to variable loads and constraints. In particular, thread root and fillet under-head drawings for metric ISO thread, which are the most commonly used thread connection, are optimized with Radial Basis Functions Mesh Morphing. In metric ISO threaded connection, the root shape and the fillet under the head are circular, and from shape optimization for minimum stress concentration it is well known that the circular shape becomes seldom optimal. The study is carried out to enhance the stress concentration factor with a simple geometric parameterization using two design variables. Radial Basis Functions Mesh Morphing formulation, performed with a simple geometric parameterization, has allowed to obtain a stress reduction of up to 12%; some similarities are found in the optimized designs leading to the proposal of a new standard. The reductions in the stress are achieved by rather simple changes made to the cutting tool.

AbstractSpine surgery is based, nowadays, on the use of cutting-edge instruments that optimize the intervention processes in the operating room, with advantages that affect the patient himself. Among these, rapid prototyping is configured as a first-rate tool, thanks to its ability to detail the diagnostic treatment according to the specific pathological case under examination. An example of this technology is represented by the generation of a drilling template, to assist the surgeon in identifying the optimal direction of insertion of the pedicle screws, capable of significantly reduce intervention times, in addition to the inevitable exposure of the patient to ionizing radiation, to which he is subjected during a normal arthrodesis intervention procedure. The design of a drilling guide requires, however, a particular attention in identifying the undercuts present on the vertebral surface, those areas of the spinous process which, reported inside the cavity of the template, involve complications at the time of extraction. In parallel, it is vitally important to carry out an evaluation of its stability during its use. In this article, starting from the analysis of the interferences present during the insertion of the template, a semi-automatic correction model is proposed for the generation of a new profile of the same, which facilitates its extraction without causing injury to the vertebral regions involved from the contact with the mask.

Significant cycle time saving can be achieved in 2.5-D milling by intelligently selecting tool sequences. The problem of finding the optimal tool sequence was reduced to finding the shortest path in a single-source single-sink directed acyclic graph. The nodes in the graph represented the state of the stock after the tool named in the node was done machining and the edges represented the cost of machining. In this paper a novel method for handling tool holder collision in the graph-based algorithm for optimal tool sequence selection has been developed. The method consists of iteratively solving the graph for the shortest path, validating the solution by checking for tool holder collisions and eliminating problematic edges in the graph. Also described is a method to intelligently build the graph such that in presence of tool holder collisions, the complexity of building the graph is greatly reduced.

This paper presents the organization, theoretical background and application of a new software tool for the optimization of the technical and economical design of microturbine recuperators. The code called CHEOPE (Compact Heat Exchanger Optimization and Performance Evaluation) considered two types of recuperator concept, which proved to be the most promising for microturbine applications: the furnace-brazed plate-fin type and the welded primary surface type. The general design rules for performance evaluation of gas-gas heat exchangers are summarized and specifically applied to these two types of recuperator. Moreover, the cost equation, employed to estimate the capital cost of these types of heat exchanger, is discussed. CHEOPE can be used both for solving the sizing problem and the rating problem. With regard to the former, the code is capable of a special optimization of the recuperator matrix, which takes into account the compactness, the pressure drops and the expected cost of the device. The objective function can be customized according to the designer’s priorities. The tests performed for the validation are presented, and three case studies are illustrated for three different microturbine sizes, for a 50kW, a 100kW and a 500kW machine.

Abstract Workpiece orientation is formulated as an optimal design problem based on a discrete approximation of design surface geometry and the kinematic capabilities of the process machine tool. The primary process application addressed is three- and four-axis numerically controlled (NC) milling, although the techniques presented may be applied to machines with more general articulation. Recent developments in applied spherical geometry are employed to formulate a nonlinear optimization problem. For three-axis milling applications, by assigning a weight to each surface normal of the discrete model corresponding to the actual area it represents, the orientation is optimized such that the angle between the normals and the milling tool axis is minimized. This formulation is augmented, for four-axis milling, to incorporate limitations of the rotational degree of freedom into the optimization formulation.

Abstract The five-axis constrained and optimal orientation planning is formulated as a design optimization problem that incorporates the process machine’s kinematic constraints with the workpiece and tool geometry, to obtain a constrained setup orientation which exploits the maximum capabilities of existing machines. This work will introduce this problem, and will obtain the setup orientation for two different types of rotation structures, i.e., tool rotation and table rotation in O(N) time. Further, the obtained constrained setup orientation, will be augmented to incorporate the workpiece surface magnitude, along with different machine rotation structures, to obtain an optimal setup orientation for different machine rotation structures. The drilling process is also introduced and formulated as additional constraints to the optimization problem. The primary application of the introduced algorithms, is the machining process, where, they can efficiently reduce the number of tool motions and surface finishing processes. However, the solution is very suitable for many manufacturing applications, such as inspection, assembly, robotics, painting, welding, aerospace, electronic surface mount technology, and etc.

The main objectives of this research was to detect the specific polymorphisms responsible for observed quantitative trait loci and develop optimal strategies for genomic evaluations and selection for moderate (Israel) and large (US) dairy cattle populations. A joint evaluation using all phenotypic, pedigree, and genomic data is the optimal strategy. The specific objectives were: 1) to apply strategies for determination of the causative polymorphisms based on the “a posteriori granddaughter design” (APGD), 2) to develop methods to derive unbiased estimates of gene effects derived from SNP chips analyses, 3) to derive optimal single-stage methods to estimate breeding values of animals based on marker, phenotypic and pedigree data, 4) to extend these methods to multi-trait genetic evaluations and 5) to evaluate the results of long-term genomic selection, as compared to traditional selection. Nearly all of these objectives were met. The major achievements were: The APGD and the modified granddaughter designs were applied to the US Holstein population, and regions harboring segregating quantitative trait loci (QTL) were identified for all economic traits of interest. The APGD was able to find segregating QTL for all the economic traits analyzed, and confidence intervals for QTL location ranged from ~5 to 35 million base pairs. Genomic estimated breeding values (GEBV) for milk production traits in the Israeli Holstein population were computed by the single-step method and compared to results for the two-step method. The single-step method was extended to derive GEBV for multi-parity evaluation. Long-term analysis of genomic selection demonstrated that inclusion of pedigree data from previous generations may result in less accurate GEBV. Major conclusions are: Predictions using single-step genomic best linear unbiased prediction (GBLUP) were the least biased, and that method appears to be the best tool for genomic evaluation of a small population, as it automatically accounts for parental index and allows for inclusion of female genomic information without additional steps. None of the methods applied to the Israeli Holstein population were able to derive GEBV for young bulls that were significantly better than parent averages. Thus we confirm previous studies that the main limiting factor for the accuracy of GEBV is the number of bulls with genotypes and progeny tests. Although 36 of the grandsires included in the APGD were genotyped for the BovineHDBeadChip, which includes 777,000 SNPs, we were not able to determine the causative polymorphism for any of the detected QTL. The number of valid unique markers on the BovineHDBeadChip is not sufficient for a reasonable probability to find the causative polymorphisms. Complete resequencing of the genome of approximately 50 bulls will be required, but this could not be accomplished within the framework of the current project due to funding constraints. Inclusion of pedigree data from older generations in the derivation of GEBV may result is less accurate evaluations.

In this paper, we examine whether acquiring citizenship improves the economic assimilation of Canadian migrants. We took advantage of a natural experiment made possible through changes in the Canadian Citizenship Act of 2014, which extended the physical presence requirement for citizenship from three to four years. Using quasi-experimental methods, we found that delaying citizenship eligibility by one year adversely affected Canadian residents' wages. Access to better jobs explains a citizenship premium of 11 percent in higher wages among naturalized migrants. Our estimates are robust to model specifications, differing sampling windows to form the treatment and comparison groups, and whether the estimator is a non-parametric rather than a parametric one. We discuss how our findings are relevant to the optimal design of naturalization policies regarding efficiency and equity.
