Review of Silicon Reactivity of Self-assembled monolayer and its Properties
Abstract: In most cases, the assumption of perfect high viscosity between silicon and silver underlies the modelization of silicene on Ag(111). According to recent reports, growth does not take place on top of the Ag(111) terraces, but rather within the first layer of them. In this article, we present the results of a study that combines scanning tunnelling microscopy and density functional theory to simulate the nucleation process and reveal the …

Bidding Strategy for Building Projects Based on Game Theory
Abstract: The owners of construction projects typically apply a competitive bid process to award a contract to the qualified bidder who submits the lowest price. For the contractors, it is very difficult to decide an optimal mark-up and bid value to win the contract and at the same time to secure sustaining profitability as high as possible. For that, from the various literatures related to the bidding problems, the factors are …

Selection of effective formwork system using multi criteria decision making analysis
Abstract: Formwork is the largest single cost item in constructing cast-in place reinforced concrete structure. This project focuses on analyzing the formwork selection problem based on decisive criteria. The factors affecting the choice of the exact formwork system have been often discussed in literatures but their importances have not been distinctly formulated. Therefore, a survey was conducted to recognize the decisive criteria in the formwork selection problems and ranking of the …
