Automation in Construction > 2015 > 54 > Complete > 106-115

Bridges are essential components of transportation systems. The bidding process is the main determinant of whether a contractor is commissioned to complete a construction project. Therefore, contractors must rapidly and precisely estimate construction costs and the bid award amount. This study involved optimizing artificial intelligence models to forecast bid award amounts for bridge construction...

A mesh simplification strategy for a spatial regression analysis over the cortical surface of the brain

Franco Dassi, Bree Ettinger, Simona Perotto, Laura M. Sangalli, more

Applied Numerical Mathematics > 2015 > 90 > Complete > 111-131

We present a new mesh simplification technique developed for a statistical analysis of a large data set distributed on a generic complex surface, topologically equivalent to a sphere. In particular, we focus on an application to cortical surface thickness data. The aim of this approach is to produce a simplified mesh which does not distort the original data distribution so that the statistical estimates...

Czynniki rozwoju obszarów wzrostu i obszarów stagnacji gospodarczej w Polsce

Robert Perdał, Jan Hauke

Rozwój Regionalny i Polityka Regionalna > 2014 > 25 > 69-88

Zróżnicowanie poziomu rozwoju i jego polaryzacja są silnie akcentowanymi cechami procesu rozwoju społeczno-gospodarczego zarówno w klasycznych koncepcjach rozwoju (zwłaszcza rozwoju spolaryzowanego), jak i w ich współczesnych kontynuacjach. Prowadzi to do występowania w przestrzeni ekonomicznej obszarów wzrostu i obszarów stagnacji gospodarczej. Dlatego niezwykle istotne jest poszukiwanie odpowiedzi...

Empirical validation of meta-models of work centres in order release planning

Stefan Haeussler, Hubert Missbauer, S. Haeussler, H. Missbauer

International Journal of Production Economics > 2014 > 149 > Complete > 102-116

We consider the problem of planning future order releases in hierarchical production planning and control systems. An established research direction is the clearing function concept: The planned material flow through a production unit is modeled by inventory balance equations for WIP and final products, and the consequences of the stochastic properties of the material flow are modeled by clearing...

The determination of uniaxial compressive strength from point load strength for pyroclastic rocks

S. Kahraman, S. Kahraman

Engineering Geology > 2014 > 170 > Complete > 33-42

The point load test has often been reported as an indirect measure of compressive strength. It has been used widely in practice due to easy testing, the simplicity of specimen preparation, and possible field applications. Many researchers have investigated the relation between uniaxial compressive strength (UCS) and point load index (I _s ) for different rock types. However, there are limited...

Regression analysis of experimental data in a study of the performance of a flat flame burner

Ivan Antonov Petrov

Polityka Energetyczna > 2024 > T. 27, z. 2 > 89--104

The complex nature of the combustion process, which simultaneously obeys the laws of thermodynamics, heat transfer, aerodynamics and the chemical kinetics of oxidation reactions, makes numerical modelling very difficult and the experimental approach is currently playing a crucial role in their investigation. The modern highly developed theory of experimental design combines various analytical procedures...

A STATISTICAL ANALYSIS OF GEOLOGICAL AND ENGINEERING PREDICTORS OF OILFIELD PERFORMANCE RESPONSE: A CASE STUDY OF OILFIELDS ON THE UK CONTINENTAL SHELF

Ukari Osah, John Howell

Journal of Petroleum Geology > 47 > 2 > 173 - 190

Oilfield production is controlled by a wide range of geological and engineering parameters, many of which are at least partially interrelated. This paper uses multivariate statistical methods (principal component analysis, regression analysis and analysis of variance) to determine how these parameters are related, and which of them are most significant in controlling and predicting oilfield performance...

Jian Ouyang, Haijun Wang, Luxiang Wu, Kexin Zhang, more

Archives of Civil Engineering > 2024 > Vol. 70, nr 1 > 573--587

In order to obtain the change rule of surrounding rock structure displacement and supporting structure internal force with time during the construction of the low mountain ridge tunnel, this paper relies on the Xishan Tunnel Project as the background. During tunneling, the displacement around the tunnel, the subsidence of the surface, the internal force of the steel arch and the pressure between the...

Balázs Varbai, Richárd Wéber, Balázs Farkas, Péter Danyi, more

Advances in Materials Science > 2024 > Vol. 24, nr 1(79) > 72--85

The crude distillation unit is the most critical elements in the refining process. Moreover, most of the equipment in the distillation unit are made of general carbon steels. Data analysis models, machine learning techniques can predict corrosion degradation rates. We used Pearson’s correlation coefficient and multiple linear regression, to predict the impact of process parameters. Altogether, we...

Ordering behavior in a supply chain with customers that respond to changes in service level

Somak Paul, Nathan Craig, Elliot Bendoly

Decision Sciences > 55 > 1 > 88 - 103

The presence of service‐level‐dependent demand has been empirically observed in industry and is well‐documented in the literature. How does the implicit contractual existence of such service dependency impact the ordering decisions of upstream suppliers? We conduct three controlled laboratory experiments to study the impact a service‐reward mechanism may have on the upstream ordering decisions of...
