Meta-raps: Parameter Setting And New Applications
… specific problem studied in this dissertation is parameter setting of Meta-RaPS. The topic of parameter setting for meta-heuristics has not been extensively studied in the literature. Although the parameter setting method devised in this dissertation is used primarily on Meta-RaPS, it is …

Universal Grammar Parameter-Setting Model Revisited: Korean Learners' Acquisition of English Anaphora
… Grammar, researchers have attempted to use the Parameter-Setting Model to explain the intricate nature of adult second language acquisition. This dissertation investigates the validity of applying the Subset Principle in second language contexts by examining Korean learners' acquisition of …

User aid-based evolutionary computation for optimal parameter setting of image enhancement and segmentation
… the image processing techniques need a control parameter setting. The better these parameters are set the better results can be achieved. Usually, these parameters are real numbers so search space is really large and brute-force searching is impossible or at least very time consuming. Therefore, …

Using Genetic Algorithms to Detect Security Related Software Parameter Chains
… applications. These configurations consist of parameters that can be individually set to control different aspects of the system. Many cyber attacks can be attributed to misconfigured software. Exploits can be caused by a single parameter setting or a combination of settings. Identifying these …

Simulink toolbox for L1 adaptive control
… L1 control. It starts with a brief idea on what parameters define an L1 controller. The document then explains how our toolbox provides an interface for selecting those parameters. Following the interface is a short review of inner working of the toolbox. Finally, setup and results of validation …

A reproducible approach to equity backtesting
… reproducability. Data collection and cleaning, parameter setting, algorithm development and report generation are often done with manual point-and-click tools which do not log user actions. This problem is compounded by the fact that the trial-and-error approach of researchers increases the …

Automatic image analysis methods for use with local operators
… technical background, want no part in adjusting parameters. This paper proposes a method of examining small windows of the image to derive parameter settings autonomously. Histograms allow rudimentary measures to be used in setting parameters for edge detection, non-linear filters, and point …

The acquisition of the Pro-drop parameter by non-native speakers of Spanish
Chomsky's (1981, 1995) principles and parameters proposal for language acquisition theory assumes that the child is genetically endowed with principles of Universal Grammar. These principles interact with environmental data to determine the particular language that the child will learn. Research …

Flexible link aerator for dissolved oxygen generation in tiger prawn pond
… the dissolved oxygen is one of the important parameters that need to be monitored seriously. Aerator is normally used to increase the level of dissolved oxygen in water. It functions to circulate or mixes the water top to bottom to ensure that the oxygen content is uniform throughout the pond. …

Predictive Control For Dynamic Systems To Track Unknown Input In The Presence Of Time Delay
… method is applied when designing the controller, parameter setting is carried out through error and trail technique in w-plane. State space equation is derived for the system, with special state chose of tracking error. To analyze the asymptotic stability of the proposed predictive control system, …

Modelling of solder interconnection’s performance in photovoltaic modules for reliability prediction
… of results shows the design with optimal parameter setting to be: TIMC -2.5μm, TSJ -20μm and WSJ -1000μm. In addition, the optimized model has 16,264 cycles to failure which is 18.82% more than the expected 13,688 cycles to failure of a PV module designed to last for 25 years.

Effect of silicon carbide (SiC) on mechanical and physical properties of solid state recycled aluminium aa6061 by using hot extrusion method
… Failure (ETF) and Microhardness (MH). The best parameter setting for the extrusion was found to be at T=550°C, t=1 hour and SiC=5 wt.%. This parameter resulted in UTS=18022 MPa, ETF=18.07%, MH=71.52Hv, and Density=2.73 g/cm3. Based on RSM, with desirability of 87.67%, the optimum parameter …

Non-Gaussian Stochastic Process Priors for Learning
… while maintaining the Brownian motion as an edge parameter setting. In this work, we review the theoretical background required to study non-Gaussian behaviour in continuous-time dynamical systems and spatio-temporal models based on L\'evy processes and their extensions. Specifically, we present …

Real-time parameter adjustment for archival image scanning
… requires the manual adjustment of several parameters to obtain the best results for a given document. Because of this manual adjustment, human intervention was often required, and conversion speeds were drastically reduced. In order to remove the need for manual adjustments, an Automatic …

Article semantics in second language acquisition
This thesis examines article choice and parameter-setting in second language (L2) acquisition. It argues, on the basis of L2-English elicitation and production data, that L2- learners have access to UG-based semantic distinctions governing article choice, but do not know which distinction is …

Setting parameters in MRP for the effective management of bought-out inventory in a JIT assembly environment
… interactions between the numerous control parameters used. Methodologies/models are developed to set these parameters. The models are based on the Pareto principle. The idea is to use business targets to set a coherent set of parameters, which not only enables those business targets to be …
