This article explores the role of ‘robustness-notions’ in an account of the engineering sciences. The engineering sciences aim at technological production of, and intervention with phenomena relevant to the (dis-)functioning of materials and technological devices, by means of scientific understanding thereof. It is proposed that different kinds of robustness-notions enable and guide scientific ...

Stability criteria are proposed for two variable D polynomials having interval parameters in polynomic uncertain ty structures Both the left half plane and unit circle domains are considered Save for a minor condition the criteria reduce robust stability testing of D polynomials to testing positivity of only two polynomials The appealing feature of the new robustness criteria is that positivity...

In this paper, we propose a biclustering-based approach to identify dishonest advisors (who provide misleading opinions about sellers), while evaluating seller trustworthiness on multiple criteria. It considers correlation between advisors’ ratings to various criteria and trust transitivity to accurately filter the dishonest advisors. Evaluation results demonstrate the robustness of our approac...

Multiwavelet transform has received attention in image watermarking because it is possible to construct multiwavelets that simultaneously possess desirable properties. Since the choice of appropriate multiwavelet basis is a critical issue that affects the quality of the watermarked image and the robustness of the watermark, we selected five different multiwavelet bases in this paper to evaluate...

flexibility as an ability to respond to changing circumstances is one of the vital characteristics of the natural and built environment. during the contemporary era, diversity of methods relating the architectural flexibility execution are suggested. but along with contemporary conceptual approaches toward pluralism and uncertainty, it seems that the multiplicity of approaches toward flexibilit...

in this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. a two-stage stochastic linear programming approach is used to maximize the expected profit. decisions such as the production amount, the inventory level of finished and semi-finished product, t...

In this paper we address the problem of segmenting a trajectory based on spatiotemporal criteria. We require that each segment is homogeneous in the sense that a set of spatiotemporal criteria are fulfilled. We define different such criteria, including location, heading, speed, velocity, curvature, sinuosity, curviness, and shape. We present an algorithmic framework that allows us to segment an...

This paper discusses FEM-based simulations of soft bodies in terms of speed and robustness. To be physically plausible, three fundamental laws must be respected: rotational invariance, Newton’s law and Euler’s law. We show that precomputed strain-displacement matrices generate nonphysical torques which can lead to visual artifacts. We then derive the fastest FEM-based method meeting our criteri...

The influence of the rotor time constant mismatch on the global stability of induction motors under indirect field oriented control (IFOC) is analyzed. A test for global stability is provided, based on necessary and sufficient conditions for the existence of quadratic Lyapunov functions for IFOC drives. This test yields robustness margins with respect to rotor time constant mismatches. A typica...

This paper studies the robustness of discriminatively trained acoustic models for large vocabulary continuous speech recognition. Popular discriminative criteria maximum mutual information (MMI), minimum phone error (MPE), and minimum phone frame error (MPFE), are used in the experiments, which include realistic mismatched conditions from Finnish Speecon corpus and English Wall Street Journal c...
