Comparison of ICC and CCC for assessing agreement for data without and with replications

The intraclass correlation coefficient (ICC) has been traditionally used for assessing reliability between multiple observers for data with or without replications. Definitions of different versions of ICCs depend on the assumptions of specific ANOVA models. The parameter estimator for the ICC is usually based on the method of moments with the underlying assumed ANOVA model. This estimator is consistent only if the ANOVA model assumptions hold. Often these ANOVA assumptions are not met in practice and researchers may compute these estimates without verifying the assumptions. ICC is biased if the ANOVA assumptions are not met. We compute the expected value of the ICC estimator under a very general model to get a sense of the population parameter that the ICC estimator provides. We compare this expected value to another popular agreement index, concordance correlation coefficient (CCC), which is defined without ANOVA assumptions. The main findings are reported for data without replication and with replications for three types of ICCs defined by one-way ANOVA model, two-way ANOVA model without interaction and two-way ANOVA model with interaction. A blood pressure example is used for illustration. If the ICC is the choice of agreement index, we recommend to use over other ICCs as its estimate is similar to the estimate of CCC regardless whether the ANOVA assumptions are met or not.     

网构软件中实体发现和排序的TEA方法(英文)

自治软件实体分布在开放、动态和多变的互联网中,它们的协作构成网构软件的基础。动态连接模式是网构软件重要的协作方式。在该模式下,如何选择具有所需质量的软件实体,是一个非常困难的任务。介绍了运行时测试和自动化测试技术,提出网构软件的自动化运行时测试方法。总结网构软件中用于软件实体的发现和排序的解决方法,提出了测试和评估方法TEA。网构软件不知道候选软件实体的质量,通过进行自动化的运行时测试,TEA可以选择具有更高质量的实体。如同网构软件一样,自治软件实体也可以在运行时改变自身结构。通过使用确认断言来评估每次实体调用的结果,TEA可以尽早发现实体变化引起的质量问题。TEA中的软件实体注册机收集每个不同的网构软件反馈的测试和评估结果信息,可以产生按估计质量排序的实体列表。在模拟实验中,TEA产生的有序列表获得最好的评估分数。

A framework for and empirical study of algorithms for traffic assignment

Traffic congestion is an issue in most cities worldwide. Transportation engineers and urban planners develop various traffic management projects in order to solve this issue. One way to evaluate such projects is traffic assignment (TA). The goal of TA is to predict the behaviour of road users for a given period of time (morning and evening peaks, for example). Once such a model is created, it can be used to analyse the usage of a road network and to predict the impact of implementing a potential project. The most commonly used TA model is known as user equilibrium, which is based on the assumption that all drivers minimise their travel time or generalised cost. In this study, we consider the static deterministic user equilibrium TA model.The constant growth of road networks and the need of highly precise solutions (required for select link analysis, network design, etc.) motivate researchers to propose numerous methods to solve this problem. Our study aims to provide a recommendation on what methods are more suitable depending on available computational resources, time and requirements on the solution. In order to achieve this goal, we implement a flexible software framework that maximises the usage of common code and, hence, ensures comparison of algorithms on common ground. In order to identify similarities and differences of the methods, we analyse groups of algorithms that are based on common principles. In addition, we implement and compare several different methods for solving sub-problems and discuss issues related to accumulated numerical errors that might occur when highly accurate solutions are required.     

Methodology for the evaluation and selection of microprocessors for specific applications

A methodology using a selection algorithm is specified by which engineers can select a microprocessor for a particular application. Such an automated procedure is of practical value because a wide variety of microprocessors are available in the market today. The practicality of the methodology is demonstrated by two applications (fast Fouriér transform using the Cooley-Tukey algorithm, and cyclic redundancy code checking in protocols) with Intel 8085, 8086, Z80 and MC 6800 microprocessors.     

A comparison of methods and computation for multi-resolution low- and band-pass transforms for image processing

The processing of images on multiple levels of resolution is often an effective and efficient tool in image analysis. For these reasons, it has met with increasing use in recent years. In this paper, past work of different authors is consolidated to introduce, review, and compare different general methods for obtaining both the multiple low-pass and multiple band-pass transformations. The methods include those using the FFT and frequency domain filtering, and spatial domain filtering using both separable and non-separable filter kernels. In addition, an original treatment of comparative computational costs is given for each of the methods described, as a function of image and filter sizes.
