With ever-increasing pollution and scarcity of resources, structural optimization, the science of finding the optimal structural arrangements under equilibrium constraints, is becoming an increasing necessity in engineering practice. However, designers are hesitant to adopt a method that is by nature a limit state and thus potentially unreliable. This thesis embeds a level of safety, namely redundancy, within the structural optimization process. Redundancy is the ability to remove a certain number of elements from the structure without losing stability. The thesis translates this constraint into a linear mathematical optimization problem. Then, a topology optimization algorithm is developed that identifies the least volume structure with the ability to remove any element(s) while maintaining stability under the initial loading. Besides the developed algorithm, this thesis shows the relation between the internal forces of redundant structures and their substructures, and in fact shows that it can be expressed linearly when only 1 level of redundancy is provided, and polynomial for higher levels. The algorithm is eventually implemented and extensively analyzed for a series of configurations, showing that redundant optimal shapes have considerably less volume than twice that of the pure volumetric optimal, and hence effectively combine safety with material efficiency. Overall, this thesis constitutes the early stage of a novel structural optimization algorithm that is unique to its volumetric optimization objectives.

Full textIsotropic robots can be postured in such a way that the condition number of their Jacobian matrices can attain a minimum value of unity. It is shown in the thesis that this feature is closely related to the performance of the robot. It appears that trajectories that are close to the set of isotropic postures are performed with smaller errors than trajectories lying far from that set.
The experiments reported here were conducted on the McGill-IRIS C3 Arm, an isotropic, four-revolute redundant manipulator, used to position the operation point of its end link. (Abstract shortened by UMI.)

Full textThe objectives of this research were to determine if mechanically-fastened steel built-up axially-loaded tension members are resistant to complete cross-sectional fracture when a single component suddenly fractures and if so, to develop simplified methods of analysis for post-fracture load redistribution behavior for calculation of remaining fatigue life. The ability to resist complete member failure and perform at a predetermined level of reliability with a failed component is referred to as internal member redundancy (IMR). The experimental program included seven full-scale tests; five were extremely demanding fracture tests, including one specimen with a tack weld placed in the path of a running fracture, and the other two were full-scale specimens removed from a 1940’s era built-up riveted deck truss, which were partially failed and tested to calibrate finite element models. Comprehensive finite element model-based parametric studies were carried out investigating the post-fracture load redistribution behavior and resulting stress amplification for multi-component, angle-only, and two-channel type axial members. Simplified closed-form solutions were developed for members of any geometry that fall within these broad categories of built-up axially-loaded tension members.
The IRM evaluation process is intended to combine the concepts related to probability of detection (POD) of fatigue cracks on steel bridges with the fatigue damage tolerance of mechanically-fastened built-up members. Preliminary results from ongoing POD research at Purdue University suggests that the steel bridge industry has unknowingly been relying on internal redundancy of mechanically-fastened built-up members. In other words, due to the difficulty of finding small cracks in components of built-up members, it is more likely that traditional arms-length inspections of fracture-critical members will find broken components instead. More candidly stated, this research provides the industry with quantitative analysis for the purpose of establishing rational inspection intervals for built-up axial members that are realistic about what can be reliably found during inspections and for what duration undiscovered damage can be safely tolerated due to internal member redundancy of the mechanically-fastened built-up member.

Cloud services are changing the world by providing millions of people low-cost access to the computing power of data centers. Storing and processing data on shared servers in the cloud provides scalability and flexibility to these services. However the large-scale sharing of resources also causes unpredictable fluctuations in the response time of individual servers. In this thesis we use redundancy as a tool to combat this variability. We study three areas of cloud infrastructure: cloud computing, distributed storage, and streaming communication. In cloud computing, replicating a task on multiple machines and waiting for the earliest copy to finish can reduce service delay. But intuitively, it costs additional computing resources, and increases queueing load on the servers. In the first part of this thesis we analyze the eect of redundancy on queues. Surprisingly, there are regimes where replication not only reduces service delay but also reduces queueing load, thus making the system more ecient. Similarly, we can speed-up content download from cloud storage systems by requesting multiple replicas of a le and waiting for any one. In the second part of the thesis we generalize from replication to coding, and propose the (n, k) fork-join model to analyze the delay in accessing an (n, k) erasure-coded storage system. This analysis provides practical insights into how many users can access a piece of content simultaneously, and how fast they can be served. Achieving low latency is even more challenging in streaming communication because the packets need to be delivered fast and in-order. The third part of this thesis develops erasure codes to transmit redundant combinations of packets and ensure smooth playback. This thesis blends a diverse set of mathematical tools from queueing, coding theory, and renewal processes. Although we focus on cloud infrastructure, the techniques and insights are applicable to other systems with stochastically varying components.

Full textAt the onset, a novel formalism is introduced to study modular kinematic structures. This includes some new concepts and definitions. The proposed formalism provides a systematic way to represent a complex hybrid manipulator through a hierarchy of its constituting modules. Next, a formulation is devised to study the instantaneous kinematics of these manipulators. The proposed formulation is general and can be applied to most of the existing parallel and hybrid manipulators. To realize the concept of general hybrid manipulator in practice, a few prototype designs are also introduced. The proposed prototypes are superior to their conventional counterparts in terms of dexterity and the volume of their workspace.
The study is then extended to the theory of hyper-redundant manipulators that comprise, as a subclass, the variable-geometry trusses. A spline-based solution method is proposed for the inverse kinematics of hyper-redundant manipulators. The method is applicable to both extensible and nonextensible cases and includes planar as well as spatial manipulators. Also, a new variable-geometry truss is introduced whose modules themselves are kinematically redundant.
Another practical aspect of redundancy is the use of redundant-sensor data to simplify inherent nonlinear direct kinematics of parallel manipulators. For a six-degree-of-freedom general parallel manipulator, we introduce a formulation of the direct kinematics whereby the positioning and orientation problems are decoupled by introducing two auxiliary parameters in the forms of either two angles or two lengths. This is in accordance with the type of redundant sensors, i.e., rotary or translational, to be used. Moreover, a real-time implementation of extra-sensor data, with a unique direct kinematics solution, is proposed by resorting to an eigenvalue problem. The parallelism in the proposed formulation enables the user to benefit from a parallel-computing environment. Hence, we introduce a parallel-computing algorithm that highly increases the robustness of the computational algorithm.
The concept of kinematic isotropy has been used as a criterion in the design of serial and parallel robotic manipulators. However, all notions adopted to express isotropy in parallel manipulators have been based on the structure of the Jacobian matrices of serial manipulators. Here, we introduce a definition of kinematic isotropy that is well-suited to parallel manipulators. This is done by identifying the special structure of the Jacobian matrices involved in the differential kinematics of such manipulators. This leads to a partitioning of the Jacobian matrices into submatrices with dimensionally homogeneous entries. Moreover, based on the proposed definitions of isotropy and kinematic optimality, a set of conditions is derived that provides a systematic way for the optimum kinematic design of parallel manipulators, with or without structural constraints.

This project analyzes designs for physical redundancy which are modeled abstractly as a bipartite graph. The goal is to determine the characteristics of graph structures which optimize the trade-off between the number of edges and the number of redundant components or nodes needed while correcting a deterministic number of worst-case errors. This thesis looks at finite-sized designs, asymptotically large designs with finite error correcting values, and designs with asymptotically large error correcting values. Results include some small optimal graph structures and fundamental limits on what the optimal design structure can achieve for the cases where a small number of errors are corrected and for where the number of errors to be correctly grows asymptotically.

Full textIn this thesis, a new redundancy-based packet-loss-concealment scheme is presented. Many redundancy-based packet-loss-concealment schemes send a fixed amount of extra information about the current packet as part of the subsequent packet, but not every packet is equally important for packet loss concealment. We have developed an algorithm to determine the importance of packets and we propose that extra information should only be sent for the important packets. This provides a lower average bit-rate compared to sending the same amount of extra information for each and every packet. We use a linear prediction (LP) based speech coder (ITU-T G.723.1) as a test platform and we propose that only the excitation parameters should be sent as extra information since LP parameters of a frame can be estimated using the LP parameters of the previous frame. Furthermore, we propose that excitation parameters of an important frame that are sent as redundant information should be used in the reconstruction of the lost waveform---as a consequence, the states of the subsequent frame will also be updated.

Full textDuring the last 15 years embedded systems have grown rapidly in complexity and performance to a point where theynow rival the design challenges of desktop systems. Embedded systems are now targets for contradictory requirements: they are expected to occupy a small amount of physical space (e.g., low package count), be inexpensive, consume low power and be highly reliable. Regardless of the decades of intensive research and development, there are still areas that can promise significant benefits if further researched. One such area is the quality of the data which embedded system operates upon. This includes both code and data segments of an embedded system application. This work presents a unified, compiler-driven approach to solving the redundancy problem. It attempts toincrease the quality of the data stream that embedded systems are operating upon while preserving the original functionality. The code size reduction is achieved by Huffman compressing or tailor encoding the ISA of the original program. The data segment size reduction is accomplished by modified Discrete Dynamic Huffman encoding. This work is the first such study that also details the design of instruction fetch mechanisms for the proposed compression schemes.

As technology scales, the improved speed and energy eciency make the successive- approximation-register (SAR) architecture an attractive alternative for applications that require high-speed and high-accuracy analog-to-digital converters (ADCs). In SAR ADCs, the key linearity and speed limiting factors are capacitor mismatch and incomplete digital-to-analog converter (DAC)/reference voltage settling. In this the- sis, a sub-radix-2 SAR ADC is presented with several new contributions. The main contributions include investigation of using digital error correction (redundancy) in SAR ADCs for dynamic error correction and speed improvement, development of two new calibration algorithms to digitally correct for manufacturing mismatches, design of new architecture to incorporate redundancy within the architecture itself while achieving 94% better energy eciency compared to conventional switching algorithm, development of a new capacitor DAC structure to improve the SNR by four times with improved matching, joint design of the analog and digital circuits to create an asynchronous platform in order to reach the targeted performance, and analysis of key circuit blocks to enable the design to meet noise, power and timing requirements. The design is fabricated in standard 1P9M 65nm CMOS technology with 1.2V supply. The active die area is 0.083mm² with full rail-to-rail input swing of 2.4V p-p . A 67.4dB SNDR, 78.1dB SFDR, +1.0/-0.9 LSB₁₂ INL and +0.5/-0.7 LSB₁₂ DNL are achieved at 50MS/s at Nyquist rate. The total power consumption, including the estimated calibration and reference power, is 2.1mW, corresponding to 21.9fJ/conv.- step FoM. This ADC achieves the best FoM of any ADCs with greater than 10b ENOB and 10MS/s sampling rate.

Full textLes canaux de communications sont vulnérables aux sources de bruit. De ce fait, n'importe quelle donnée transmise sur ces canaux peut être victime d'erreurs survenant lors de la transmission, dégradant ainsi la qualité du signal à la réception. Afin de résoudre ce problème, une certaine redondance doit être apportée au signal d'entrée pour qu'à la réception elle aide à corriger les erreurs. Cependant, la plupart des schémas ajoutant de la redondance aux signaux ont deux défauts majeurs. Premièrement, ces schémas sont conçus pour fonctionner décemment aussi longtemps que la qualité du canal reste au dessus d'un certain seuil. Mais dés que la qualité du canal tombe en dessous de ce seuil, le système est complètement perturbé et n'est plus capable de corriger les erreurs (effet de seuil). Deuxièmement, la plupart des schémas de correction d'erreurs courantes manquent d'adaptabilité et de flexibilité propres pour modifier la redondance ajoutée, ce qui est nécessaire au vue des changements inévitables des caractéristiques du canal. Dans cette thèse, nous explorons les méthodes de représentation du signal qui se prêtent naturellement à la transmission à des taux flexibles et qui offrent une dégradation graduelle (graceful degradation) en termes de qualité de signal par rapport à la détérioration du canal. Pour de telles applications, nous considérons l'insertion d'une redondance de type soft et structurée dans les signaux à transmettre en utilisant les bancs de filtres sur-échantillonnés (Oversampled Filter Bank : OFB). Ces codes offrent à la fois une compression et une protection des signaux grâce à l'application d'une transformation redondante (ou opérateur de frame) au signal, ce qui sert au prétraitement des signaux pour la compression et pour l'insertion de redondance dans le signal, permettant ainsi de contrer les effets indésirables du canal. Plus précisément, dans cette thèse, nous approfondissons le domaine des expansions redondantes de signal au cas où la quantité de redondance injectée peut être ajustée à la volée. Deux approches principales permettront cette entreprise. La première méthode est appelée sous-échantillonnage adaptatif. L'idée est de changer le taux de sous-échantillonnage de l'OFB en réponse aux variations de la qualité du canal. Nous étudions l'effet d'un tel sous-échantillonnage sur le filtrage des vecteurs du signal d'entrée du coté analyse et nous proposons une méthode de reconstruction du signal appropriée du coté synthèse de l'OFB. Pour la deuxième méthode, nous introduisons la notion d'effacement instantané dans les OFB, qui correspond au cas où les échantillons des vecteurs sous-bande sont effacés avec une distribution arbitraire à différents moments. Nous trouvons les conditions pour lesquelles l'OFB maintient sa propriété de reconstruction parfaite en utilisant une analyse temporelle et nous proposons des structures afin de permettre la conception d'OFB implémentables.

Full textThe Church of Sweden in Norrköping are currently faced with a virtual intranet that they feel could be improved. Some of the problems they have identified are unusual traffic forwardin patterns, exhaustion of the IP adress pool and a high level of complexity. In addition, they feel that it might be time to increase the bandwidth that some of the buildings have access to. My goal with this paper – based on the largest parishes and Kyrkan Hus, where the organization’s IT office and server farm lies – is to give recommendations in terms of actions and changes that could mitigate these issues and hopefully provide a more future proof solution. During my work I have taken some rudimentary baseline readings, IP addressing tables and compilations of network flows, in order to create a current situation analysis, which I have used to draw some of my conclusions. I have also aimed to illustrate the problems that have formed the foundation for this work. In my report I have also discussed some modern IT trends, such as thin clients, virtual environments and BYOD, Bring Your Own Device. This assignment has resulted in a general design proposal with redundant links, guest networks and Ipv6 support, with different alternatives withing each aspect, which can be used to further tailor the implementations of the different technologies. For a more all encompassing, thorough design of the intranet as a whole we’d need a more complete documentation, together with approximations and evaluations regarding network usage, IP addressing and budget.

Manufacturing a DRAM module that is error free is a very difficult process. This process is becoming more difficult when only utilizing the current methods for producing an error free DRAM. Error correction codes (ECCs) and cell replacement are two methods currently used in isolation of each other in order to solve two of the problems with this manufacturing process: increasing reliability and increasing yield, respectively. Possible solutions to this problem are proposed and evaluated qualitatively in discussion. Also, a simulation model is produced in order to simulate the impacts of various strategies in order to evaluate their effectiveness.

Full textThis master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data.
The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected. On the other hand, if the channel quality is too good for the used coding scheme, LQC should recommend a faster coding scheme with less redundancy.
The testing tool is now using a static coding schme that doesn’t change during a data session. An LQC is therefore necessary for better simulation of the traffic and to make the tests more real.
