This paper describes heuristic algorithms for scheduling preemptive, imprecise, composite tasks with input error and end-to-end timing constraints. Each composite task consists of a chain of component tasks, where each component task is made up of a mandatory part and an optional part. Whenever a component task uses imprecise input, the mandatory and optional parts of the component task may be ...

This paper proposes a neural network model that extracts axes of symmetry from visual patterns. The input patterns can be line drawings, plane figures or gray-scaled natural images taken by CCD cameras. The model is a hierarchical multi-layered network, which consists of a contrast-extracting layer, edgeextracting layers (simple and complex types), and layers extracting symmetry axes. Its archi...

This paper attempts a normative assessment of the input and output-oriented legitimacy of the present euro-rescuing regime on the basis of policy analyses examining the causes of present crises, the available policy options, and the impact of the policies actually chosen. Concluding that the regime lacks input-oriented legitimacy and that its claim to output-oriented legitimacy is ambivalent at...

In this paper we propose a method for applications oriented input design for linear systems under time-domain constraints on the amplitude of input and output signals. The method guarantees a desired control performance for the estimated model in minimum time, by imposing some lower bound on the information matrix. The problem is formulated as a timedomain optimization problem, which is non-con...

is thesis is divided into two main parts. e first part considers applicationoriented input design, specifically for model predictive control (MPC). e second part considers alternating direction method of multipliers (ADMM) for l1 regularized optimization problems and primal-dual interior-point methods. e theory of system identification provides methods for estimating models of dynamical sys...

Data Envelopment Analysis (DEA) is a powerful quantitative tool that provides a means to obtain useful information about efficiency and performance of firms, organizations, and all sorts of functionally similar, relatively autonomous operating units, known as Decision Making Units (DMU). Usually the investigated DMUs are characterized by a vector of multiple inputs and multiple outputs. Unfortu...

The concept of devicevs. task-orientation allows to identify subtasks that are especially prone to errors. Device-oriented tasks occur whenever a user interface requires additional steps that do not directly contribute to the users’ goals. They comprise, but are not limited to, initialization errors and postcompletion errors (e.g., removing a bank card after having received money). The vulnerab...

This paper presents a formal framework for process-oriented modeling and analysis of organizations. The high expressivity of a sorted predicate logic language LPR used for specifying process-oriented models allows representing a wide range of process-related concepts (e.g., tasks, processes, resources), their characteristics and relations over them, which are described in the paper. Furthermore...
