Abstract:
This research aims to determine the use of materials from reclaimed asphalt pavement layers directly with the addition of virgin aggregates without the addition of other additives (filler) intended for quality improvement based on the 2010 general specifications of the Indonesian National Standard. Utilization of these materials was used for base courses (class A), sub-base courses (class B), and courses without asphalt coverings (class S). The method used was the laboratory-experiment method and the analysis of the relationship was made using the regression equation. Based on the analysis, by combining the mixture with the virgin aggregates, it was revealed that the materials from reclaimed asphalt pavement layers can be used for the base courses by no more than 3 percent, for the sub-base courses by no more than 9 percent, and for the courses without asphalt coverings or shoulders by no more than 10 percent.

Abstract:
Advanced Materials are defined as unique combinations of materials, process technologies, that together, help create and capture value by addressing large, global unmet wants and needs of building industry. There is a wide range of innovation enabled by technologies for processing materials and integrating currently available materials for creation of new generation buildings "Titaniun" is one of them. It is an incredibly durable and stunning material known for its wide-range of color, high-tensile strength. Titanium can be processed to achieve a variety of surface textures, from a soft matte to a near gleaming reflectivity suitable for architectural application. Titanium's corrosion immunity, strength and physical properties combine to allow reduced wall thickness, lowering its installed unit cost which is favourable as far as its application in densely populated urban areas is concerned. Many countries like United Sates of America, China, and Spain etc have also stared its use however its use in developing country like India is still limited. The paper attempts to analyze the chemical properties of Titanium as a futuristic building material. It also observes the variant of the material as option to make self-cleaning buildings in the future, reducing the amount of harmful cleansers used currently.

Abstract:
This study focused on the smectogenic polysiloxane, PG296, and the nematogenic, PG375, Where noted the lower order parameter at higher molecular weight polymers, they do support the overall trend of an increased nematic range with increasing polymer concentration. The reduced solvent power of 5CB when used with the polymer PG375 might be associated with the lack of side groups of similar cyanobiphenyl structure in the polymer but could also be related to the strong dipolar anti-parallel associations that might be expected to form between the cyano terminated polymer side groups, thus locking in the backbone configuration. The elastic constants and S2 as a function of polymer concentration, where the constants decreases with increasing concentration of the solution.

Abstract:
In this study, the torsional and distortional performance of a three triangular cell trapezoidal box girder section was studied using Vlasov's theory of thin walled structures. The potential energy of a system under equilibrium was used to obtain the governing differential equations of equilibrium for torsionl-distortional analysis of the box structure. The strain modes diagrams representing torsional and distortional interactions of the box girder structure were obtained as well as the distortional bending moment diagram for the box girder structure. These were used to compute Vlasov's coefficients contained in the differential equations of equilibrium. The fourth order differential equations obtained were solved using method of trigonometric series with accelerated convergence to obtain the distortional and torsional deformations which were compared with torsional and distortional deformations of a single cell mono symmetric box girder section of similar overall dimensions and plates thicknesses. The maximum distortional deformation was found to be 168% lower than that of a single cell mono-symmetric box girder section of the same size and dimensions. The inclined internal web members, which also act as diaphragms, brought about increase in the pure torsional and distortional components of the applied torsional load, resulting to marginal increase in the torsional deformation but major decrease in the distortional deformation.
Keywords: deformation, distortion, torsion, trapezoidal box girder, triangular cells, Vlasov's theory.

[Abstract]

Abstract:
In order to drive down the cost of wind turbine cast components, the optimization of each production step is necessary. In particular, foundry moulds used for the production of cast components undergo a process of drying needed to avoid quality problems in the final parts. In order to reduce drying times forced convection by the use of fans is needed. In this work we perform Computational Fluid Dynamic studies with the aim to optimize the drying process for mould geometries typically used for the production of wind turbine components. Representative geometries are modelled in a 3D software, imported in a fluid flow solver and complete Navier-Stokes equations coupled with energy transport equations are solved. Velocity profiles from shop floor measurements are used as boundary conditions for the problem. Finally surface heat exchange coefficients are determined and results analyzed. Results show that it is possible to use this methodology to optimize the drying process, and determine areas of the moulds that are more difficult to dry than others. Optimal fan arrangement for typical geometries are also provided.
