This paper presents a system-level modeling methodology for microfluidic surface-immobilized biomolecular concentration gradient generators (CGGs). The generator is broken down into a system of elemental microfluidic components with relatively simple geometries and functionality. Parameterized models for such components are developed, which hold for general biomolecular concentration profiles and arbitrary flow ratios at the component interface; hence, they are valid for a broad category of CGGs that rely on various operating mechanisms. The component models are then linked through an appropriate set of parameters at the interfaces to construct a system-level, network representation of the entire generator for simulation. The system model is extensively verified against experimental data reported in the literature. The model results are found to be in excellent agreement, and can be applied to accurately capture the overall effects of network geometry, biomolecular properties, operating parameters (e.g., flow rates and initial biomolecular concentration) on the generation of biomolecular gradients on the surfaces. The model also demonstrates salient computational efficiency (seconds of execution time) and can be used to guide fast, reliable, system-level design of CGGs and associated bioassays.

In the construction projects, a pile group foundation is often utilized. The group of bored piles is usually installed relatively close to each other and joined at the top by a pile cap to hold up the loads. In other hand, a fast estimation of the groups of piles capacities are needed in the preliminary design and in other conditions of projects, such as a supervisor of projects want to estimate the capacities of the group of piles. The purpose of this research is to study the correlations of groups of piles efficiencies with the number of piles and to compare the groups of piles capacities with the single piles capacities. Furthermore, this study is aimed to make a fast estimation of groups of piles capacities using proposed graphical method.The piles efficiencies are calculated using several methods, such as Simplified Analysis, Converse-Labare [1][2], Los Angeles Group, Seiler - Keeney, Das, and Sayed - Baker. In order to calculate the groups of piles capacities, the capacities of single piles are needed. The singles piles capacities are taken from graphical method proposed by Djarwanti et al. (2015a and 2015b). Three graphical methods utilized are derived from the Briaud et al. (1985) , Reese and Wright (1977), and Reese O’Neill method. Moreover, the proposed graphical method is applied in the case study. The case study takes palace in Graha Indoland Condotel Inside Yogyakarta Construction Project.The pile efficiency graph is recommended for this research since the value of pile efficiency could be easily taken. The value of pile efficiency for Graha Indoland Condotel Inside using Simplified Analysis, Converse - Labare, Los Angeles Group, Seiler – Keeney, Das, and Sayed – Baker are 1,75; 0,89; 0,94; 0,99; 4,00; 1,56 respectively. Meanwhile the value of pile group capacity with the value of pile group efficiency more than 1, showed that the pile group capacity based on the efficiency is bigger than the one based on single down pattern.
