Unfortunately, floating-point arithmetic is not a sound implementation of real arithmetic, i.e., it may produce different results, does not provide error guarantees, and the errors can become arbitrarily large. In this paper, we introduce SafeGen, a source-to-source compiler that rewrites a given C program using floating-point arithmetic to an efficient C program performing the same computation soundly, i.e., it returns an error bound that is guaranteed to contain the correct result of the program if it had been executed in real arithmetic. Equivalently, it gives a precision certificate on the number of correct bits in the result. SafeGen uses affine arithmetic (AA) that keeps accuracy high compared to interval arithmetic by preserving linear correlations between variables. To mitigate its high cost, SafeGen combines a novel form of static ana lysis to identify these correlations with a flexible policy-based approach for their selection. SafeGen supports SIMD intrinsics in the input and can output SIMDoptimized code. Our results show that SafeGen-generated code is 30–70 times faster than manually rewritten code using AA libraries. Equivalently, SafeGen can offer many more bits of certified accuracy within a reduced time budget.} } @article{zhe-wan-sha-zha-liy-22-aa-powflow, author = {Zheng, Wendi and Wang, Xiangjie and Shao, Zhenguo and Zhang, Min and Li, Yixin}, title = {A Modified Affine Arithmetic-Based Interval Optimization for Integrated Energy System with Multiple Uncertainties}, journal = {Journal of Renewable and Sustainable Energy}, volume = {14}, number = {1}, pages = {016302}, year = 2022, doi = {10.1063/5.0079306}, comment = {Modified AA?}, abstract = {In integrated energy systems, uncertainties cause day-ahead scheduling plans to be uncertain rather than an exact solution. However, traditional interval optimization models ignore the correlation between variables, resulting in an over-conservative range of solutions. To overcome this limitation, the present paper proposes a modified affine arithmetic to establish an interval optimal scheduling model based on deterministic optimization. The correlation between different variables is tracked by sharing noise terms, and the solution in affine form is transformed into a more intuitive interval solution by a modified affine approximation method and linear relaxation method. Finally, with the minimum midpoint and radii of daily operating cost interval as the objective function, the multi-objective function is converted into a single-objective function through Lagrange multiplication to solve the model. In a case study, the proposed method is compared with the Monte Carlo simulation method and the traditional interval optimization method without affine arithmetic. The simulation results show that the radii of the interval solutions obtained by the proposed method is 9.39{\%} less than the traditional interval arithmetic at the 15{\%} level of uncertainty.} } @article{pep-car-vac-djo-22-aa-markov, author = {Antonio Pepiciello and Fabrizio {De Caro} and Alfredo Vaccaro and Sasa Djokic}, title = {Affine Arithmetic-Based Reliable Estimation of Transition State Boundaries for Uncertain Markov Chains}, journal = {Electric Power Systems Research}, volume = {204}, pages = {107711}, year = 2022, issn = {0378-7796}, doi = {10.1016/j.epsr.2021.107711}, abstract = {Markov Chain-based models have been extensively used in numerous power system applications, ranging from decision support systems, to reliability and resilience analysis.

In addressing that problem, this paper advocates the role of affine arithmetic, by proposing a reliable framework for Markov Chain transient analysis in the presence of data uncertainties. The main idea is to represent the uncertainties in state transition probabilities through affine forms, which then allow to apply affine arithmetic-based operators and to identify the corresponding transient state probabilities.

However, uncertainties of RESs and loads pose challenges to microgrid operation. The traditional point optimization method is unrealistic, and the widely used stochastic optimization (SO) method is time-consuming. Besides, battery energy storage systems (BESSs) are critical dispatchable devices to alleviate adverse effects of uncertainty, so an accurate nonlinear degradation cost model of BESSs should also be proposed. To handle such problems, the paper proposes an affine–arithmetic (AA)-based microgrid interval optimization (IO) method considering uncertainty and BESS degradation. First, the AA theory is introduced to model the RES and load variation ranges as intervals and calculate the interval uncertainty. Then, a nonlinear BESS degradation cost model is proposed, which can assess battery degradation costs considering different charging and dischargi ng behaviors. The nondominated sorting genetic algorithm-II (NSGA-II) is employed to solve the proposed microgrid IO framework. For validation, the proposed IO method was compared with the point optimization method and SO method under various uncertainty realizations in a modified IEEE 33 bus system. The simulation results indicated the effectiveness of the proposed IO method in terms of an equilibrium between the simulation time and optimization performance.} } %%% 2021 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% @article{dor-21-aa-routhdelgam, author = {H.

Conventional capacitor placement and sizing methods do not consider uncertainty in power injections, due to which the results may be erroneous.

However, conventional division operation in AA gives rise to extra noise terms in the resulting affine form, which are not due to the actual uncertainty sources but are due to the nonaffine operations. The present work incorporates modified AA division which does not generate any additional noises, thereby improving the accuracy. Buses in the distribution network are ranked in decreasing order of rate of change of active power loss in line with respect to the change in the effective reactive power flow in that line. The top three ranked buses are chosen as candidate buses for capacitor connection. The required affine reactive current injection at the candidate buses is calculated, and the corresponding affine capacitive kVAR required is obtained through modified AA-based backward/forward sweep (BFS) power flow analysis. The intervals for the cost incurred in losses, voltage profiles with and without capacitor are calculated, and savings for capacitor connected system is calculated. Switchable capacitors are used for reactive power injection. The proposed method is tested on 15, 33 and 118 bus radial distribution systems.

It uses a specialised root-finding algorithm to simulate analogue circuits with parameter variations in one single simulation run. This is a significant speed-up compared to the multiple runs needed by industrialised solutions such as Monte-Carlo (MC) or Worst-Case Analysis (WCA). Currently, AGIAS can simulate analogue circuits only under very specific conditions. In many cases, circuits can only be simulated for certain operating points. If the circuits is to be evaluated in other operating points, the solver becomes numerically unstable and simulation fails. In these cases, interval widths approach infinity. Behavioural modelling of analogue circuits was introduced by researchers working around limitations of simulators. Most early approaches require expert knowledge and insight into the circuit which is modelled. In recent y ears, Machine Learning techniques for automatic generation of behavioural models have made their way into the field. This thesis combines Machine Learning techniques with affine arithmetic to include the effects of parameter variations into models. Support Vector Machines (SVMs) train two sets of parameters: one slope parameter and one offset parameter. These parameters are replaced by affine forms. Using these two parameters allows affine SVMs to model effects of parameter variations with varying widths. Training requires additional information about maximum and minimum values in addition to the nominal values in the data set. Based on these changes, affine ε Support Vector Machine (ε̂SVR) and ν Support Vector Machine (ν̂SVR) algorithms for regression are presented. To train the affine parameters directly and profit from the Sequential Minimal Optimisation algorithm (SMO)’s selectivity, the SMO is extended to handle the new, larger optimisation problems. The new aff ine SVMs are tested on analogue circuits that have been chosen based on whether they could be simulated with AGIAS and how strongly non-linear their characteristic function is.} } @inproceedings{che-qin-guo-liu-wei-19-aa-powdistr, author = {Cheng, Lin and Qi, Ning and Guo, Yanfei and Liu, Nan and Wei, Wei}, title = {Potential Evaluation of Distributed Energy Resources with Affine Arithmetic}, booktitle = {IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia 2019)}, year = 2019, volume = {}, number = {}, pages = {4334-4339}, doi = {10.1109/ISGT-Asia.2019.8881198}, ISSN = {2378-8542}, month = may, abstract = {With the rapid development of Energy Internet, the penetration of distributed energy resources is gradually increasing.

However, in polar coordinate systems, interval arithmetic still suffers from issues of complex computation and overestimation. This article defines a polar affine variable and develops a polar affine arithmetic (PAA) that extends affine arithmetic to the polar coordinate systems, which performs better in many aspects than the corresponding polar interval arithmetic (PIA). Basic arithmetic operations are developed based on the complex affine arithmetic. The Chebyshev approximation theory and the min-range approximation theory are used to identify the best affine approximation. PAA can accurately keep track of the interdependency among multiple variables throughout the calculation procedure, which prominently reduces the solution conservativeness. Numerical examples implemented in MATLAB programs show that, compared with benchmark results from the Monte Carlo method, the proposed PAA ensures completeness of the exact solution and presents a more compact solution region than PIA when dependency exists in the calculation process.

One of the methods used for finding solution intervals for power flow is Monte Carlo simulations. However, Monte Carlo simulations approach suffers from the drawback of large time consumption due to repeated power flows. To overcome this limitation, affine arithmetic based power flow analysis is introduced in literature which is capable of generating solution intervals to the interval power flow problem without the need of repeated power flow analysis. Multiplication operation between two affine terms in conventional affine arithmetic generates an extra noise term in the affine product. In affine based power flow analysis for distribution system, mu ltiplication operation is used repeatedly since backward/forward sweep algorithm is iterative in nature. This generates a large number of noise terms in certain affine parameters which ultimately leads to larger solution intervals for the problem. In the present work, a new formulation of complex affine multiplication is introduced for the affine arithmetic based distribution power flow analysis which does not generate any extra noise term for the resulting complex affine product. The proposed modified affine arithmetic based distribution power flow analysis is tested on IEEE 33, 69, 202 and 874 bus radial distribution systems. All the four test systems are assumed to have distributed generation.

The uncertainty of wind power causes variation of the variables of power grids, which threatens the power grids’ operating security. Therefore, it is significant to provide the accurate ranges of power grids’ variables, which can be used by the operators to guarantee the power grid’s operating security. To achieve this goal, the present paper puts forward the interval power flow with wind farms model, where the generation power outputs of wind farms are expressed by intervals and three types of control modes are considered for imitating the operation features of wind farms. To solve the proposed model, the affine arithmetic-based method and optimizing- scenarios method are modified and employed, where three types of constraints of wind control modes are considered in their solution process. The former expresses the interval variables as affine arithmetic forms, and constructs optimization models to contract the affine arithmetic forms to obtain the accurate intervals of power flow variables. The latter regards active power outputs of the wind farms as variables, which vary in their corresponding intervals, and accordingly builds the minimum and maximum programming models for estimating the intervals of the power flow variables. The proposed methods are applied to two case studies, where the acquired results are compared with those acquired by the Monte Carlo simulation, which is a traditional method for handling interval uncertainty. The simulation results validate the advantages, effectiveness and the applicability of the two methods.} } @article{liu-cai-jia-han-zha-18-aa-intinv, author = {Jie Liu and Heng Cai and Chao Jiang and Xu Han and Zheng Zhang}, title = {An Interval Inverse Method Based on High Dimensional Model Representation and Affine Arithmetic}, journal = {Applied Mathematical Modelling}, volume = {63}, pages = {732-743}, year = 2018, doi = {10.1016/j.apm.2018.07.009}, comment = {AA for interval inverse problems}, abstract = {This paper proposes an interval inverse method through a high dimensional model representation and affine arithmetic, which can effectively solve inverse problems with interval uncertainty.

Therefore, a mixed interval power flow (MIPF) is established to incorporate merits of RIPF in computing intervals of voltage phase and PIPF's advantages in evaluating intervals of voltage magnitude. The IEEE118 system is analyzed to conclude that MIPF can acquire more accurate power flow interv als than PIPF.} } @article{zou-pen-cai-wuh-hul-16-aa-forens, author = {Tiefang Zou and Haitao Peng and Ming Cai and Hequan Wu and Lin Hu}, title = {A {Taylor}-Affine Arithmetic for Analyzing the Calculation Result Uncertainty in Accident Reconstruction}, journal = {Forensic Science International}, volume = {266}, pages = {502-510}, year = 2016, issn = {0379-0738}, doi = {10.1016/j.forsciint.2016.07.011}, comment = {Application of AA to forensics, eg car accident reconstruction}, abstract = {In order to analyze the uncertainty of a reconstructed result, the Interval Algorithm (IA), the Affine Arithmetic (AA) and the Modified Affine Arithmetic (MAA) were introduced firstly, and then a Taylor-Affine Arithmetic (TAA) was proposed based on the MAA and Taylor series.

A particular challenge is the sensitivity of analog parts to even small deviations in parameters, or inputs. Parameters of circuits and systems such as process, voltage, and temperature are never accurate; we hence model them as uncertain values (`ncertainties'). Uncertain parameters and inputs can modify the dynamic behavior and lead to properties of the system that are not in specified ranges. For verification of mixed- signal systems, the analysis of the impact of uncertainties on the dynamical behavior plays a central role. Verification of mixed-signal systems is usually done by numerical simulation. A single numerical simulation run allows designers to verify single parameter values out of often ranges of uncertain values. Multi-run simulation techniques such as Monte Carlo Simulation, Corner Case simulation, and enhanced techniques such as Importance Sampling or Design -of-Experiments allow to verify ranges – at the cost of a high number of simulation runs, and with the risk of not finding potential errors. Formal and symbolic approaches are an interesting alternative. Such methods allow a comprehensive verification. However, formal methods do not scale well with heterogeneity and complexity. Also, formal methods do not support existing and established modeling languages. This fact complicates its integration in industrial design flows. In previous work on verification of Mixed-Signal systems, Affine Arithmetic is used for symbolic simulation. This allows combining the high coverage of formal methods with the ease-of use and applicability of simulation. Affine Arithmetic computes the propagation of uncertainties through mostly linear analog circuits and DSP methods in an accurate way. However, Affine Arithmetic is currently only able to compute with contiguous regions, but does not permit the representation of and computation with discre te behavior, e.g. introduced by software. This is a serious limitation: in mixed-signal systems, uncertainties in the analog part are often compensated by embedded software; hence, verification of system properties must consider both analog circuits and embedded software. The objective of this work is to provide an extension to Affine Arithmetic that allows symbolic computation also for digital hardware and software systems, and to demonstrate its applicability and scalability. Compared with related work and state of the art, this thesis provides the following achievements: 1. The thesis introduces extended Affine Arithmetic Forms (XAAF) for the representation of branch and merge operations. 2. The thesis describes arithmetic and relational operations on XAAF, and reduces over-approximation by using an LP solver. 3. The thesis shows and discusses ways to integrate this XAAF into existing modeling languages, in particular SystemC. This way, breaks in the design flow can be av oided. The applicability and scalability of the approach is demonstrated by symbolic simulation of a Delta-Sigma Modulator and a PLL circuit of an IEEE 802.15.4 transceiver system.} } @inproceedings{rad-gri-16-aa-formal, author = {Radojicic, Carna and Grimm, Christoph}, title = {Formal Verification of Mixed-Signal Designs Using Extended Affine Arithmetic}, booktitle = {2016 12th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)}, year = 2016, volume = {}, number = {}, pages = {1-4}, doi = {10.1109/PRIME.2016.7519482}, month = jun, comment = {Formal verification of signal processing hardware.

As alternatives, range based approaches can be used. They model parameter uncertainties as ranges. The simulation outputs are ranges which include all possible results created by the parameter uncertainties. One type of range arithmetic is the affine arithmetic, which allows to maintain linear correlations to avoid over-approximation. An equation solver based on affine arithmetic has been proposed earlier. Unlike many other range based approaches it can solve implicit non-linear equations. This is necessary for analog circuit simulation. For large unc ertainties the solver suffers from convergence problems. To overcome these problems it is possible to split the parameter ranges, calculate the solutions separately and merge them again. For higher dimensional systems this leads to excessive runtimes as each parameter is split. To minimize the additional runtime several split and merge strategies are proposed and compared using two analog circuit examples.} } @inproceedings{abe-pas-mud-16-aa-powflow, author = {Abebe, Yoseph Mekonnen and Pasumarthi, Mallikarjuna Rao and Mudavath, Gopichand Naik}, title = {Load Flow Analysis of Uncertain Power System Through Affine Arithmetic}, booktitle = {Microelectronics, Electromagnetics and Telecommunications - Proceedings of ICMEET 2015}, series = {LNEE}, number = {372}, year = 2016, publisher = {Springer}, address = {New Delhi}, pages = {217--231}, isbn = {978-81-322-2728-1}, abstract = {On this paper a novel load flow analysis using complex affine arithmetic (AA) based on Gauss-Seidel method for uncertain system is proposed.

Non-affne operations are realized through the introduction of a new noise, that accounts for nonlinear terms.

With floating-point arithmetic, an issue is to handle roundoff errors and to incorporate them in the final result, so as to satisfy the inclusion property, which is the fundamental property of interval arithmetic. In [4], [5] and [6], roundoff errors are accounted for in a manner that implies frequent switches of the rounding mode; this incurs a severe time penalty. Implementations of these variants are available in YalAA, developed by Kiel [2]. We propose an implementation that uses one dedicated noise symbol for accumulated roundoff errors. For accuracy purposes, the roundoff error $\epsilon$ of each arithmetic operation is computed exactly via EFT (Error Free Transforms). For efficiency purposes, the rounding mode is never switched. Instead, a brute-force bound on the roundoff error $\varepsilon$ incurred by the accumulation of the $\epsilon$s mentioned above is used. Experimental results are presented. The proposed implementation is one of the most accurate and its execution time is significantly reduced; it can be up to 50{\%} faster than other implementations.

A variety of methods are available in the literature to perform power flow, transient, and voltage stability analyses considering uncertainties associated with electrical parameters.} } @article{lin-qin-lia-xio-14-aa-surfint, author = {Lin, Hongwei and Qin, Yang and Liao, Hongwei and Xiong, Yunyang}, journal = {IEEE Transactions on Visualization and Computer Graphics}, title = {Affine Arithmetic-Based {B}-Spline Surface Intersection with {GPU} Acceleration}, year = 2014, volume = {20}, number = {2}, pages = {172-181}, doi = {10.1109/TVCG.2013.237}, ISSN = {1941-0506}, month = feb, comment = {Intersection of parametric surfaces.

As is well known, affine arithmetic is robust for calculating the surface intersection because it is able to not only find every branch of the intersection, but also deal with some singular cases, such as surface tangency. However, the classical affine arithmetic is defined only for the globally supported polynomials, and its computation is very time consuming, thus hampering its usefulness in practical applications, especially in geometric design. In this paper, we extend affine arithmetic to calculate the range of recursively and locally defined B-spline basis functions, and we accelerate the affine arithmetic-based surface intersection algorithm by using a GPU. Moreover, we develop efficient methods to thin the strip-shaped intersection regions produced by the affine arithmetic-base d intersection algorithm, calculate the intersection points, and further improve their accuracy.

The obtained affine forms of arbitrary functions provide faster and tighter function range evaluation. Several case studies for operations using affine forms are presented. The proposed techniques for surface interrogation are tested using ray-surface intersection for ray-tracing and spatial cell enumeration for polygonisation.

Using AA reduces the complexity without loosing generality of the simulation results. This paper covers the formulation of effective highlevel circuit models.

What is ``Chebyshev'' AA?}, abstract = {Due to the hard-to-measure distributions of real process data, it is difficult to provide accurate parametric yield prediction for modern circuit design. Most existing approaches are not able to handle the uncertain distribution properties coming from the process data. Other approaches are inadequate in considering correlations among the distributions of variations. This paper suggests a new approach that not only takes care of correlations among distributions but also provides a low-cost and efficient computation scheme. The proposed method approximates the parameter variations with Chebyshev affine arithmetic (CAA) to capture both the uncertainty and nonlinearity in a cumulative distribution function. The CAA-based probabilistic range presentation describes, both fully and partially, specified process and environmental parameters. Thus, we are able to predict the probability bounds for leakage consumption with unknown dependences among variations. The end resu lt is the chip-level parametric yield estimation based on leakage prediction. Experimental results demonstrate that the new approach provides a reliable bound estimation, which leads to a 20{\%} yield improvement compared with only using the intervals of partially specified uncertainties.} } @article{bah-rev-08-aa-equilib, author = {Baharev, Ali and R{\'e}v, Endre}, title = {Reliable Computation of Equilibrium Cascades with Affine Arithmetic}, journal = {Journal of the American Institute of Chemical Engineers}, volume = {54}, number = {7}, pages = {1782-1797}, doi = {10.1002/aic.11490}, year = 2008, comment = {Chemical equilibrium equations. Combining AA with other methods}, abstract = {Computing the steady state of multistage counter-current processes like distillation, extraction, or absorption is the equivalent to finding solutions for large-scale nonlinear equation systems. The conventional solution techniques are fast and efficient if a good estimation is available, but are prone to fail, and do not provide information about the reason for the failure. This is the main motive to apply reliable methods in solving them. Reliable computations are usually realized with interval methods. A reliable root finding method is presented, based on affine arithmetic (AA), a recently developed linearization technique and interval method. AA is compared here to another linearization technique, the widely known Interval Newton method. The studied examples seem to indicate superiority of the novel method over the traditional one. The comparison is made with a pruning technique not state-of-the-art, but analogous in the two compared methods. AA can be combi ned with constraint propagation (CP), or linear programming (LP) aided CP, as pruning techniques. The combined techniques, AA/CP and AA/LP are studied and compared. AA/LP proves to be preferable because of its robustness. Short distillation columns are successfully computed with the proposed AA/LP method.} } @misc{gou-put-08-aa-perturb, title = {Perturbed Affine Arithmetic for Invariant Computation in Numerical Program Analysis}, author = {Eric Goubault and Sylvie Putot}, year = 2008, howpublished = {Preprint online at the arXiv repository, article 0807.2961}, url = {https://arxiv.org/abs/0807.2961}, comment = {Finding invariants of numerical algorithms}, abstract = {We completely describe a new domain for abstract interpretation of numerical programs.

See also~\cite{cho-05-aa-expert}.}, abstract = {Expert knowledge consists of statements $S_j$ (facts and rules). The facts and rules are often only true with some probability. For example, if we are interested in oil, we should look at seismic data. If in 90{\%} of the cases, the seismic data were indeed helpful in locating oil, then we can say that if we are interested in oil, then with probability 90{\%} it is helpful to look at the seismic data. In more formal terms, we can say that the implication ``if oil then seismic'' holds with probability 90{\%}. Another example: a bank $A$ trusts a client $B$, so if we trust the bank $A$, we should trust $B$ too; if statistically this trust was justified in 99{\%} of the cases, we can conclude that the corresponding implication holds with probability 99{\%}. If a query $Q$ is deducible from facts and rules, what is the resulting probability $p(Q)$ in $Q$? We can describe the truth of $Q$ as a propositional formula $F$ in terms of $S_j$, i.e., as a combination of sta tements $S_j$ linked by operators like $\wedge$, $\vee$, and $\neg$; computing $p(Q)$ exactly is NP-hard, so heuristics are needed. Traditionally, expert systems use technique similar to straightforward interval computations: we parse $F$ and replace each computation step with corresponding probability operation. Problem: at each step, we ignore the dependence between the intermediate results $F_j$; hence intervals are too wide. Example: the estimate for $P(A\vee \neg A)$ is not 1. Solution: similar to affine arithmetic, besides $P(F_j)$, we also compute $P(F_j\wedge F_i)$ (or $P(F_{j1}\wedge \cdots \wedge F_{jd})$), and on each step, use all combinations of $\ell$ such probabilities to get new estimates. Results: e.g., $P(A\vee\neg A)$ is estimated as 1.} } @article{miy-kas-07-aa-exist, author = {Shinya Miyajima and Masahide Kashiwagi}, title = {Existence Test for Solution of Nonlinear Systems Applying Affine Arithmetic}, journal = {Journal of Computational and Applied Mathematics}, volume = {199}, number = {2}, pages = {304-309}, year = 2007, note = {Special Issue on Scientific Computing, Computer Arithmetic, and Validated Numerics (SCAN 2004)}, issn = {0377-0427}, doi = {10.1016/j.cam.2005.08.051}, comment = {Existence test using Newton criterion?}, abstract = {A computational test is proposed for existence of solution in nonlinear systems.

We have developed an automated and efficient bit-width optimization methodology that is Affine Arithmetic (AA) based. Experiments have proven that, compared to the previous static analysis methods, our methodology not only dramatically reduces the fractional bit-width by more than 35{\%} but also slightly reduces the integer bit-width. In addition, our probabilistic error analysis method further enlarges the bit-width-to-error tradeoff.} } %%% 2005 %%%%%%%%%%%%%%%%%%% @inproceedings{zou-zha-cai-zho-hon-05-aa-timing, author = {Yi Zou and Mengsheng Zhang and Yici Cai and Qiang Zhou and Xianlong Hong}, title = {Minimum Error Based Affine Arithmetic for Variational Timing Analysis}, booktitle = {6th International Conference on ASIC}, year = 2005, volume = {2}, number = {}, pages = {978-981}, doi = {10.1109/ICASIC.2005.1611491}, ISSN = {2162-755X}, month = oct, comment = {Aplication to timing analysis of electronic circuits.

Application to ray tracing}, abstract = {A method for ray casting implicit surfaces, defined with procedural noise models, is presented. The method is robust in that it is able to guarantee correct intersections at all image pixels and for all types of implicit surfaces. This robustness comes from the use of an affine arithmetic representation for the quantity that expresses the variation of the implicit function along a ray. Affine arithmetic provides a bounding interval estimate which is tighter than the interval estimates returned by conventional interval arithmetic. Our ray casting method is also efficient due to a proposed modification in the data structure used to hold affine arithmetic quantities. This modified data structure ultimately leads to a reduced affine arithmetic model. We show that such a reduced affine arithmetic model is able to retain all the tight estimation capabilities of standard affine arithmetic, in the context of ray casting implicit procedural noises, while being faster to compute and more efficient to store. We also show that, without this reduced model, affine arithmetic would not have any advantage over the more conventional interval arithmetic for ray casting the class of implicit procedural surfaces that we are interested in visualizing.} } @inproceedings{jam-acu-05-aa-neural, booktitle = {Advances in Neural Networks: Proc.

Therefore, it is essential to estimate the thermal state of transformers during load cycling and, in presence of overload conditions, to evaluate the need to reduce the load current or to install another transformer bay. A method of solving the transformer's thermal model, considering explicitly the source of uncertainty affecting its parameters, is required.

In this context accurate thermal rating assessment of overhead lines represents an essential requirement in order to obtain a sensible increase of the infrastructure exploitation assuring at the same time a reliable functioning of the power networks. This necessitates reliable calculation models which should be able to predict the thermal behaviour on short and long time horizons and in the presence of data uncertainties deriving from several sources such as nonstationary load and fluctuating operating conditions. To address this problem, in the paper the use of Affine Arithmetic, an enhanced model for numerical computation, is proposed. Using AA, the thermal rating solution is computed taking into account the model parameter uncertainty interdependencies as well as the diversity of uncertainty sources. Simulation studies ar e presented and discussed in order to prove the effectiveness of the proposed methodology in addressing the problem of uncertainty analysis in both static and dynamic thermal rating assessment.} } @article{miy-miy-kas-03-aa-newdiv, author = {Shinya Miyajima and Takatomi Miyata and Masahide Kashiwagi}, title = {A New Dividing Method in Affine Arithmetic}, journal = {IEICE TRANSACTIONS on Fundamentals of Electronics, Communications and Computer Sciences} volume = {E86-A}, number = {9}, pages = {2192-2196} year = 2003, month = sep, issn = {0916-8508}, comment = {Improved division algorithm}, abstract = {Affine arithmetic is a kind of interval arithmetic defined by Stolfi et al.

This integration technique is based on the confidence estimates of each cue. We use affine forms to bound these confidences. Affine forms represent bounded intervals, with a well-defined set of arithmetic operations. They are constructed from the sum of several independent components. An n-dimensional affine form describes a complex convex polytope, called a zonotope. Because these components lie in bounded intervals, Lindeberg's theorem, a modified version of the central limit theorem,can be used to justify a Gaussian approximation of the affine form. We present a new expectation-based algorithm to find the best Gaussian approximation of an affine form. Both the new and the previous algorithm run in $O(n 2m)$ time, where $n$ is the dimension of the affine form, and $m$ is the number of independent components. The constants in the running time of new algorithm, however, are much smaller, and as a result it runs 40 times faster than the previous one for equal inputs. We show that using the Berry-Esseen theorem it is possible to calculate an upper bound for the error in the Gaussian approximation. Using affine forms and the conversion algorithm, we create a method for automatically integrating cues in the tracking process of a deformable model. The tracking process is described as a dynamical system, in which we model the force contribution of each cue as an affine form. We integrate their Gaussian approximations using a Kalman filter as a maximum likelihood estimator. This method not only provides an integrated result that is dependent on the quality of each on of the cues, but also provides a measure of confidence in the final result. We evaluate our new estimation algorithm in experiments, and we demonstrate our deformable model-based face tr acking system as an application of this algorithm. } } @inproceedings{lem-hed-bar-02-aa-circ, author = {Andreas Lemke and Lars Hedrich and Erich Barke}, title = {Analog Circuit Sizing Based on Formal Methods using Affine Arithmetic}, booktitle = {Proc.

We treat each cue as a random variable, each of which is the sum of a large number of local contributions with unknown probability distribution functions. Under the assumption that these distributions are independent, the overall distributions of the generalized cue forces can be approximated with multidimensional Gaussians, as per the central limit theorem. Estimating the covariance matrix of these Gaussian distributions, however, is difficult, because the probability distributions of the local contributions are unknown. We use affine arithmetic as a novel approach toward overcoming these difficulties. It lets us track and integrate the support of bounded distributions without having to know their actual probability distributions, and without having to make assumptions about their properties. We present a method for converting t he resulting affine forms into the estimated Gaussian distributions of the generalized cue forces. This method scales well with the number of cues. We apply a Kalman filter as a maximum likelihood estimator to merge all Gaussian estimates of the cues into a single best fit Gaussian. Its mean is the deterministic result of the algorithm, and its covariance matrix provides a measure of the confidence in the result. We demonstrate in experiments how to apply this framework to improve the results of a face tracking system.} } @inproceedings{wer-paj-01-omatch, author = {T. Werner. and T.

It is common for surfaces defined by implicits to be located using interval arithmetic. However, the method only gives conservative bounds for the values of the function inside a region of interest. This paper gives two possible ways of producing tighter bounds. One involves using a Bernstein–form representation of the implicit polynomials used as input to the method. The other fine–tunes the method itself by employing careful use of affine arithmetic—a more sophisticated version of interval arithmetic. As both methods contribute significant improvements, we speculate about combining the two into a fast and accurate method for surface location.} } @inproceedings{pin-rez-00-cccc, author = {G.

Stolfi's book is basically really good, although it does have some flaws; unfortunately in my review I concentrated on the flaws. Now that I'm older and, if not wiser, at least a little less unkind, I would write about what's good --- the underlying ideas, the beautiful formulations of things, the accessibility of the work, and the important applications --- and be less picky about details, and the fact that oriented projective geometry is really more or less equivalent to "spherical geometry," which was known and developed by Riemann. Riemann, of course, did prove a good deal about the sphere, but Stolfi tells us things that are computationally important and worthwhile, but which weren't really even reasonable questions in Riemann's day.

Through a combination of algorithm design and careful engineering of the implementation, the resulting program can triangulate a set of random rational points in the unit circle only four to five times slower than can a floating-point implementation of the algorithm. The algorithms, engineering process, and software tools developed are described.}, altkeys = {Karasick:1991:EDT} } @article{web-laf-sta-91-puzz, author = {Roger W. Webster and Paul S.

This problem has important applications in bio-medical research and instruction, solid modeling, and industrial inspection. The problem can be broken into four subproblems, the correspondence problem, the tiling problem, the branching problem, and the surface fitting problem. We describe our system for surface reconstruction from sets of contours with respect to each of these subproblems. Special attention is given to the correspondence and branching problems. We present a method which can handle sets of contours in which adjacent contours share a very contorted boundary.} } @techreport{bro-her-91-form, author = {Marc H.

It was conjectured to be a review of J. Stolfi's % "Oriented Projective Geometry" % published in the American Mathematics Monthly, year unknown, June issue, % page 479. % That review was thought to have been cited by Toussaint in % and article called \emph{Computational Geometry} % Proc. IEEE 80 (9), 1347--1363; Sep 1992. % However, Toussaint actually cited the "Oriented Projective Geometry" % book directly; the following entry in the bibliography was an % article by M. G. Stone, "A mnemonic for areas of polygons", % AMM june-july 1986, 479--480. The Citeseer crawler apparently % fused the two entries.
