The proposed feature selection method enhances the predictive performance of the models, with the GA-ANN model demonstrating the highest predictive performance. Optimal solutions for FAH concrete mix design under different optimization conditions were obtained....
In several test series the fresh and hardened concrete properties of concretes with reduced water and cement content were investigated, especially their workability, strength development, design-relevant mechanical properties, and durability aspects such as carbonation and resistance against sulfate attack. ...

Concrete Mix Design: Principles, Calculations, and a Worked Example by Omotoriogun Victor This article provides a step-by-step guide to concrete mix design using the DOE (Department of Environment) method. A fully detailed worked example demonstrates each calculation, ensuring clarity and practical...
which the game takes place. Usually, this falls to the head designer given the complexity and depth of the design challenge – creating an entire world isn’t easy. It must accompany the plot and set the tone for the game, creating a concrete map that players can follow as they progress...
design principles for future OS schedulers, and discuss the implications of each for OS and runtime interfaces and structure. We illustrate the implementation challenges that result by describing the concrete choices we have made in the Barrelfish multikernel. This allows us to present ...
Finally, the last section discusses how Sachs’s eco-development was ultimately envisioned as a theory of the planning of alternative, emancipatory and sustainable, development projects and explores the concrete nature of this novel approach. Toward a structuralist theory of (un)sustainability Facing ...
Wood-based materials are particularly important to the success of sustainable climate mitigation because, when well-sourced through selective logging and existing forest plantations, they have much smaller carbon footprints than building alternatives such as steel and concrete. However, unsustainable timber ...
One of the key differences between ITIL and COBIT is while COBIT outlines what needs to be done, ITIL describes ways to do it. With each iteration of ITIL, IT professionals get concrete, actionable steps they can implement to improve their service delivery. Can COBIT and ITIL work in tandem...
