Abstract:
The use of mechanical pointers in optical tracking systems is needed to aid registration processes of unlocated rigid bodies. Error on the target point of a pointer can cause wrong positioning of vital objects and as such these errors have to be avoided. In this paper, the different errors that originate during this process are described, after which this error analysis is used for the optimisation of an improved pointer design. The final design contains six coplanar fiducials, favored by its robustness and low error. This configuration of fiducials is then analysed theoretically as well as practically to understand how it is performing. The error on tracking the target point of the pointer is found with simulation to be around 0.7 times the error of measuring one fiducial in space. However, practically this error is about equal to the fiducial tracking error, due to the non-normally distributed errors on each separate fiducial.

Abstract:
The paper presents an approach concerning the CMM design. The first stage of this research deals with the acquisition and the development of knowledge about the CMM design. The main mechanical design aspects to achieve a high positioning and measuring accuracy are presented and two main objectives are assigned: high repeatability (design for repeatability) and high predictability of the machine response to the main error sources (design for predictability). In the second stage of this research the dynamic errors states for this CMM design have been analyzed. In high-speed measuring processes dynamic errors will have a great influence on the accuracy. This study has been performed by using finite-element analysis (FEA) of the mechanical frame. The total deformation of the mechanical frame for different accelerations of the moving assemblies has been calculated. The major deflections at the probe position due to the accelerations are obtained by using FEA. These results give a prediction about the dynamic error of the CMM.

Abstract:
Control over scale, dynamic, environment, and geometric errors in 5-axis machine tool are required to realize a high precision machine tool. Especially geometric errors such as translational, rotational, offset, and squareness errors are important factors which should be considered in the design stages of the machine tool. In this paper, geometric errors are evaluated for different configurations of 5-axis machine tool, namely, 1) table tilting, 2) head tilting, and 3) universal and their error synthesis models are derived. The proposed model is different from the conventional error synthesis model since it considers offset and offset errors. The volumetric error is estimated for every configuration with random geometric errors. Finally, the best configuration, the critical design parameter and error are suggested.

Abstract:
Mistake proofing uses changes in the physical design of processes to reduce human error. It can be used to change designs in ways that prevent errors from occurring, to detect errors after they occur but before harm occurs, to allow processes to fail safely, or to alter the work environment to reduce the chance of errors. Effective mistake proofing design changes should initially be effective in reducing harm, be inexpensive, and easily implemented. Over time these design changes should make life easier and speed up the process. Ideally, the design changes should increase patients’ and visitors’ understanding of the process. These designs should themselves be mistake proofed and follow the good design practices of other disciplines.

Abstract:
O avanço das tecnologias de circuitos integrados (CIs) levanta importantes questões relacionadas à confiabilidade e à robustez de sistemas eletrônicos. A diminuição da geometria dos transistores, a redução dos níveis de tensão, as menores capacitâncias e portanto menores correntes e cargas para alimentar os circuitos, além das freqüências de relógio elevadas, têm tornado os CIs mais vulneráveis a falhas, especialmente àquelas causadas por ruído elétrico ou por efeitos induzidos pela radiação. Os efeitos induzidos pela radiação conhecidos como Soft Single Event Effects (Soft SEEs) podem ser classificados em: Single Event Upsets (SEUs) diretos em nós de elementos de armazenagem que resultam em inversões de bits; e pulsos transientes Single Event Transients (SETs) em qualquer nó do circuito. Especialmente SETs em circuitos combinacionais podem se propagar até os elementos de armazenagem e podem ser capturados. Estas errôneas armazenagens podem também serem chamadas de SEUs indiretos. Falhas como SETs e SEUs podem provocar erros em operações funcionais de um CI. Os conhecidos Soft Errors (SEs) são caracterizados por valores armazenados erradamente em elementos de memória durante o uso do CI. SEs podem produzir sérias conseqüências em aplicações de CIs devido à sua natureza não permanente e não recorrente. Por essas razões, mecanismos de proteção para evitar SEs através de técnicas de tolerância a falhas, no mínimo em um nível de abstração do projeto, são atualmente fundamentais para melhorar a confiabilidade de sistemas. Neste trabalho de dissertação, uma versão tolerante a falhas de um microprocessador 8-bits de produção em massa da família M68HC11 foi projetada. A arquitetura é capaz de tolerar SETs e SEUs. Baseado nas técnicas de Redundância Modular Tripla (TMR) e Redundância no Tempo (TR), um esquema de proteção foi projetado e implementado em alto nível no microprocessador alvo usando apenas portas lógicas padrões. O esquema projetado preserva as características da arquitetura padrão de tal forma que a reusabilidade das aplicações do microprocessador é garantida. Um típico fluxo de projeto de circuitos integrados foi desenvolvido através de ferramentas de CAD comerciais. Testes funcionais e injeções de falhas através da simulação de execuções de benchmarks foram realizados como um teste de verificação do projeto. Além disto, detalhes do projeto do circuito integrado tolerante a falhas e resultados em área, performance e potência foram comparados com uma versão não protegida do microprocessador. A área do core aumentou 102,64 % para proteger o circuito alvo contra SETs e SEUs. A performance foi degrada em 12,73 % e o consumo de potência cresceu cerca de 49 % para um conjunto de benchmarks. A área resultante do chip robusto foi aproximadamente 5,707 mm².
The advance of the IC technologies raises important issues related to the reliability and robustness of electronic systems. The transistor scale by shrinking its geometry, the voltage reduction, the lesser capacitances and therefore smaller currents and charges to supply the circuits, besides the higher clock frequencies, have made the IC more vulnerable to faults, especially those faults caused by electrical noise or radiationinduced effects. The radiation-induced effects known as Soft Single Event Effects (Soft SEEs) can be classified into: direct Single Event Upsets (SEUs) at nodes of storage elements that result in bit flips; and Single Event Transient (SET) pulses at any circuit node. Especially SETs on combinational circuits might propagate itself up to the storage elements and might be captured. These erroneous storages can be also called indirect SEUs. Faults like SETs and SEUs can provoke errors in functional operations of an IC. The known Soft Errors (SEs) are characterized by values stored wrongly on memory elements during the use of the IC. They can make serious consequences in IC applications due to their non-permanent and non-recurring nature. By these reasons, protection mechanisms to avoid SEs by using fault-tolerance techniques, at least in one abstraction level of the design, are currently fundamental to improve the reliability of systems. In this dissertation work, a fault-tolerant IC version of a mass-produced 8-bit microprocessor from the M68HC11 family was designed. It is able to tolerate SETs and SEUs. Based on the Triple Modular Redundancy (TMR) and Time Redundancy (TR) fault-tolerance techniques, a protection scheme was designed and implemented at high level in the target microprocessor by using only standard logic gates. The designed scheme preserves the standard-architecture characteristics in such way that the reusability of microprocessor applications is guaranteed. A typical IC design flow was developed by means of commercial CAD tools. Functional testing and fault injection simulations through benchmark executions were performed as a design verification testing. Furthermore, fault-tolerant IC design issues and results in area, performance and power were compared with a non-protected microprocessor version. The core area increased by 102.64 % to protect the target circuit against SETs and SEUs. The performance was degraded in 12.73 % and the power consumption grew around 49 % for a set of benchmarks. The resulting area of the robust chip was approximately 5.707 mm².

Abstract:
When designing a lens, cost and manufacturing concerns are extremely challenging, especially with radical optical designs. The tolerance process is the bridge between design and manufacturing. Three techniques which improve the interaction between lens design and engineers are successfully shown in this thesis along with implementation of these techniques. First, a method to accurately model optomechanical components within lens design is developed and implemented. Yield improvements are shown to increase by approximately 3% by modeling optomechanical components. Second, a method utilizing aberration theory is applied to discover potential tolerance sensitivity of an optical system through the design process. The use of aberration theory gives an engineer ways to compensate for errors. Third, a method using tolerance grade mapping is applied to error values of an optical system. This mapping creates a simplified comparison method between individual tolerances and lens designs.

Abstract:
Future wireless networks will be required to support multimedia traffic in addition to traditional best-effort network services. Supporting multimedia traffic on wired networks presents a large number of design problems, particularly for networks that run connectionless data transport protocols such as the TCP/IP protocol suite. These problems are magnified for wireless links, as the quality of such links varies widely and uncontrollably. This dissertation presents new tools developed for the design and realization of wireless networks including, for the first time, analytical channel models for predicting the efficacy of error control codes, interleaving schemes, and signalling protocols, and several novel algorithms for matching and adapting system parameters (such as error control and frame length) to time-varying channels and Quality of Service (QoS) requirements.

Abstract:
The pervasive nature of modern computer systems has led to an increase in our reliance on such systems to provide correct and timely services. Moreover, as the functionality of computer systems is being increasingly defined in software, it is imperative that software be dependable. It has previously been shown that a fault intolerant software system can be made fault tolerant through the design and deployment of software mechanisms implementing abstract artefacts known as error detection mechanisms (EDMs) and error recovery mechanisms (ERMs), hence the design of these components is central to the design of dependable software systems. The EDM design problem, which relates to the construction of a boolean predicate over a set of program variables, is inherently difficult, with current approaches relying on system specifications and the experience of software engineers. As this process necessarily entails the identification and incorporation of program variables by an error detection predicate, this thesis seeks to address the EDM design problem from a novel variable-centric perspective, with the research presented supporting the thesis that, where it exists under the assumed system model, an efficient EDM consists of a set of critical variables. In particular, this research proposes (i) a metric suite that can be used to generate a relative ranking of the program variables in a software with respect to their criticality, (ii) a systematic approach for the generation of highly-efficient error detection predicates for EDMs, and (iii) an approach for dependability enhancement based on the protection of critical variables using software wrappers that implement error detection and correction predicates that are known to be efficient. This research substantiates the thesis that an efficient EDM contains a set of critical variables on the basis that (i) the proposed metric suite is able, through application of an appropriate threshold, to identify critical variables, (ii) efficient EDMs can be constructed based only on the critical variables identified by the metric suite, and (iii) the criticality of the identified variables can be shown to extend across a software module such that an efficient EDM designed for that software module should seek to determine the correctness of the identified variables.

Abstract:
I Am Error is a platform study of the Nintendo Family Computer (or Famicom), a videogame console first released in Japan in July 1983 and later exported to the rest of the world as the Nintendo Entertainment System (or NES). The book investigates the underlying computational architecture of the console and its effects on the creative works (e.g. videogames) produced for the platform. I Am Error advances the concept of platform as a shifting configuration of hardware and software that extends even beyond its ‘native’ material construction. The book provides a deep technical understanding of how the platform was programmed and engineered, from code to silicon, including the design decisions that shaped both the expressive capabilities of the machine and the perception of videogames in general. The book also considers the platform beyond the console proper, including cartridges, controllers, peripherals, packaging, marketing, licensing, and play environments. Likewise, it analyzes the NES’s extension and afterlife in emulation and hacking, birthing new genres of creative expression such as ROM hacks and tool-assisted speed runs. I Am Error considers videogames and their platforms to be important objects of cultural expression, alongside cinema, dance, painting, theater and other media. It joins the discussion taking place in similar burgeoning disciplines—code studies, game studies, computational theory—that engage digital media with critical rigor and descriptive depth. But platform studies is not simply a technical discussion—it also keeps a keen eye on the cultural, social, and economic forces that influence videogames. No platform exists in a vacuum: circuits, code, and console alike are shaped by the currents of history, politics, economics, and culture—just as those currents are shaped in kind.

Includes bibliographical references (page 68).
System dynamics modelling is used to explore varying levels of concurrency in a typical design-build-produce project introducing a new product. Faster product life-cycles and demanding schedules have introduced the importance of beginning downstream work (build/manufacturing) while upstream work (design) is incomplete. Conceivably, this project concurrency improves project schedule and cost by forcing rework to be discovered and completed earlier in the project life. Depending on the type of project, some design errors may only be discoverable once the build phase has begun its work. Namely, systemic errors and assembly errors that cannot be easily discovered within the design phase. Pushing build activity earlier in the project allows the rework to be discovered earlier in the project, shortening the overall effort required to complete the project. A mathematical simulation, created using Vensim@ system modeling software, was created by James Lyneis to simulate two-phase rework cycles. The model was tuned to match data based on a disguised real project. Various start dates (as a function of project percentage complete) for downstream phases were explored to find optimal levels of concurrency. Project types were varied by exploring three levels of "rework discoverable within the design phase" to cover a range of project types. The simulation found that for virtually all project types, significant schedule and effort benefits can be gained by introducing the downstream phase as early as 30% to 40% into the project progress and ramping downstream effort over an extended period of time.

Abstract:
As integrated circuit density increases, digital circuits characterized by high operating frequencies and low voltage levels will be increasingly susceptible to faults. Furthermore, it has recently been shown that for many digital signature and identification schemes an attacker can inject faults into the hardware and the resulting incorrect outputs may completely expose their secrets. On-chip error masking techniques such as error correction could be one of the options to mitigate the above problems. To this end, this thesis presents a framework of techniques to design error circuits.

Abstract:
Abstract The modeling of manufacturing errors in mechanisms is a significant task to validate practical designs. The use of probability distributions for errors can simulate manufacturing variations and real world operations. This paper presents the mechanical error analysis of universal joint drivelines. Each error is simulated using a probability distribution, i.e., a design of the mechanism is created by assigning random values to the errors. Each design is then evaluated by comparing the output error with a limiting value and the reliability of the universal joint is estimated. For this, the design is considered a failure whenever the output error exceeds the specified limit. In addition, the problem of synthesis, which involves the allocation of tolerances (errors) for minimum manufacturing cost without violating a specified accuracy requirement of the output, is also considered. Three probability distributions — normal, Weibull and beta distributions — were used to simulate the random values of the errors. The similarity of the results given by the three distributions suggests that the use of normal distribution would be acceptable for modeling the tolerances in most cases.

Abstract:
Abstract A higher order version of the Error Matrix Method is proposed to increase the accuracy in the finite element error localization. The method retains a user specified number of terms from the appropriate binomial expansion. Jacobi’s iterative method is then proposed to solve the set of nonlinear equations. It is hypothesized that keeping the higher order terms will improve the error identification for the same number of coordinate degrees-of-freedom and modes. The method is implemented on a nine degree-of-freedom and an Euler-Bernoulli beam numerical examples. It is shown that while there needs to be a large number of measured coordinates and modes, the magnitude of the errors are more accurately identified.

Full text
Abstract:
A linear relationship between the MTF degradation and the wavefront variance has been developed for small wavefront error perturbation. A sensitivity coefficient can then be defined to aid both the design and error budgeting process. For error budgeting, this coefficient is applied to predict change in performance of a nearly diffraction-limited optical imaging system due to manufacture and assembly errors. This leads to a fast and accurate way to create an error budget and explore ideal distribution of individual terms. A CODE V verification model will be presented to show the range of wavefront error that this MTF linear degradation model applied. Further, an example of an error budget spread sheet will illustrate how this model is used to determine the best distribution of error allocations.

Abstract:
Abstract This paper presents a stochastic model and a Monte Carlo computer simulation algorithm to combine all measurable non-linear kinematic and misalignment error components to predict the overall tooltip quasi-static robot spatial position accuracy for a gantry robot. These errors include joint position accuracies, joint misalignments, joint zero position offsets, axis directional straightness, squareness errors and kinematic coupling errors. All of these errors can be independently measured using a laser interferometer and/or other precision measuring instruments. The interation between robot joints and coupling between these error components are very complex making the determination of the overall robot spatial position accuracy difficult. In this paper a Monte Carlo computer simulation program for predicting overall robot spatial position accuracy based on a stochastic error model was developed. Finally, simulation results are compared with direct spatial accuracy test results using a computerized Theodolite system. This robot spatial accuracy qualification methodology has been accepted and recommended by RIA as part of American National Standard for robot accuracy evaluation.

Abstract:
This paper presents a framework for representing and deploying error-proofs (poka-yoke) in the product development process. Information technology (IT) already plays a key role in product development through tools such as numerical computation, CAD, simulations, and process planning. Information management for error-proofing in manufacturing is also quite common in many industries. However, experts agree that many field failures and quality problems stem back to errors in engineering design. While there are many case studies on design process error-proofing, one must deploy them through leveraging engineering information systems for them to be effective. Towards this goal, this paper proposes the use of quality function deployment (QFD) to characterize potential design errors, evaluate the risks, identify effective error proofing elements, and prioritize their implementation.

Abstract:
We use a total survey error approach to examine and make recommendations on how to adjust for non-sampling error in longitudinal, mixed-mode surveys. Using data from the National Crime Victimization Survey (NCVS), we examine three major sources of non-sampling error: telescoping, mode effects, and fatigue. We present an assessment of each source of error from a total survey error perspective and propose alternative adjustments to adjust better for this error. Findings suggest that telescoping and fatigue are likely sources of error in the NCVS, but the use of mixed-modes is not. Furthermore, both telescoping and fatigue are present in longitudinal surveys and accounting for one but not the other results in estimates that under- or overestimate the measures of interest—in this case, the rate of crime in the United States.

Full text
Abstract:
Considering the importance of the transportation network and bridge structures, the associated seismic design philosophy is shifting from the basic collapse prevention objective to maintaining functionality on the community scale in the aftermath of moderate to strong earthquakes (i.e., resiliency). In addition to performance, the associated construction philosophy is also being modernized, with the utilization of accelerated bridge construction (ABC) techniques to reduce impacts of construction work on traffic, society, economy, and on-site safety during construction. Recent years have seen several developments towards the design of low-damage bridges and ABC. According to the results of conducted tests, these systems have significant potential to achieve the intended community resiliency objectives. Taking advantage of such potential in the standard design and analysis processes requires proper modeling that adequately characterizes the behavior and response of these bridge systems. To evaluate the current practices and abilities of the structural engineering community to model this type of resiliency-oriented bridges, the Pacific Earthquake Engineering Research Center (PEER) organized a blind prediction contest of a two-column bridge bent consisting of columns with enhanced response characteristics achieved by a well-balanced contribution of self-centering, rocking, and energy dissipation. The parameters of this blind prediction competition are described in this report, and the predictions submitted by different teams are analyzed. In general, forces are predicted better than displacements. The post-tension bar forces and residual displacements are predicted with the best and least accuracy, respectively. Some of the predicted quantities are observed to have coefficient of variation (COV) values larger than 50%; however, in general, the scatter in the predictions amongst different teams is not significantly large. Applied ground motions (GM) in shaking table tests consisted of a series of naturally recorded earthquake acceleration signals, where GM1 is found to be the largest contributor to the displacement error for most of the teams, and GM7 is the largest contributor to the force (hence, the acceleration) error. The large contribution of GM1 to the displacement error is due to the elastic response in GM1 and the errors stemming from the incorrect estimation of the period and damping ratio. The contribution of GM7 to the force error is due to the errors in the estimation of the base-shear capacity. Several teams were able to predict forces and accelerations with only moderate bias. Displacements, however, were systematically underestimated by almost every team. This suggests that there is a general problem either in the assumptions made or the models used to simulate the response of this type of bridge bent with enhanced response characteristics. Predictions of the best-performing teams were consistently and substantially better than average in all response quantities. The engineering community would benefit from learning details of the approach of the best teams and the factors that caused the models of other teams to fail to produce similarly good results. Blind prediction contests provide: (1) very useful information regarding areas where current numerical models might be improved; and (2) quantitative data regarding the uncertainty of analytical models for use in performance-based earthquake engineering evaluations. Such blind prediction contests should be encouraged for other experimental research activities and are planned to be conducted annually by PEER.

Full text
Abstract:
This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the design and implementation of a wave model evaluation system, altWIZ, which uses wave height observations from operational satellite radar altimeters. The altWIZ system utilizes two recently released altimeter databases: Ribal and Young (2019) and European Space Agency Sea State Climate Change Initiative v.1.1 level 2 (Dodet et al. 2020). The system facilitates model evaluation against 1 Hz1 altimeter data or a product created by averaging altimeter data in space and time around model grid points. The system allows, for the first time, quantitative analysis of spatial model errors within the U.S. Army Corps of Engineers (USACE) Wave Information Study (WIS) 30+ year hindcast for coastal United States. The system is demonstrated on the WIS 2017 Atlantic hindcast, using a 1/2° basin scale grid and a 1/4° regional grid of the East Coast. Consistent spatial patterns of increased bias and root-mean-square-error are exposed. Seasonal strengthening and weakening of these spatial patterns are found, related to the seasonal variation of wave energy. Some model errors correspond to areas known for high currents, and thus wave-current interaction. In conjunction with the model comparison, additional functions for pairing altimeter measurements with buoy data and storm tracks have been built. Appendices give information on the code access (Appendix I), organization and files (Appendix II), example usage (Appendix III), and demonstrating options (Appendix IV).

Full text
Abstract:
Concepts for real-time grading of fruits and vegetables were developed, including multi-spectral imaging with structured illumination to detect and distinguish surface defects from concavities. Based on these concepts, a single-lane conveyor and inspection system were designed and evaluated. Image processing algorithms were developed to inspect and grade large quasi-spherical fruits (peaches and apples) and smaller dried fruits (dates). Adjusting defect pixel thresholds to achieve a 25% error rate on good apples, classification errors for bruise, crack, and cut classes were 51%, 42%, and 46%, respectively. Comparable results for bruise, scar, and cut peach clases were 48%, 22%, and 58%, respectively. Acquiring more than two images of each fruit and using more than six lines of structured illumination per fruit would reduce sorting errors. Doing so, potential sorting error rates for bruise, crack, and cut apple classes were estimated to be 38%, 38%, and 33%, respectively. Similarly, potential error rates for the bruitse, scar, and cut peach classes were 9%, 3%, and 30%, respectively. Date size classification results were good: 68% within one size class and 98% within two size classes. Date quality classification results were not adequate due to the problem of blistering. Improved features were discussed. The most significant contribution of this research was the on-going collaboration with producers and equipment manufacturers, and the resulting transfer of research ideas to expedite the commercial application of machine vision for postharvest inspection and grading of agricultural products.
