One perspective of a design process in the engineering design community is that it is largely a process marked and defined by a series of decisions. The fundamental assumption in most developed design decision support methodologies is that decision makers make rational choices; that is, choices that maximize the payoff for the predicted outcome. Decisions that do not maximize the predicted payo...

Stimulating is an important mechanism in Virtual Community (VC) during the Knowledge Sharing (KS) process. In this paper, we combine the power of game theory and stimulating mechanism together to optimize the KS process in Social Network (SN). We first model the basic stimulating mechanism as a static game of complete information, under which the stimulating threshold for Nash Equilibrium (NE) ...

Hydrothermal processes are promising technologies for an efficient valorization of wet biomass feedstocks or wastes. Their performance strongly depends on the composition feedstock, and methods to analyze such complex mixtures along with produced effluents in constant progress. Herein, catalytic hydrothermal gasification (cHTG) was used valorize process water from liquefaction pine wood. A deta...

In this paper we propose several strategies for the exact computation of the determinant of a rational matrix. First, we use the Chinese Remaindering Theorem and the rational reconstruction to recover the rational determinant from its modular images. Then we show a preconditioning for the determinant which allows us to skip the rational reconstruction process and reconstruct an integer result. ...

Payroll process mostly done manually in Indonesian companies. Manual takes longer time than automated process. In this research, an employee payroll system was developed on the Odoo platform by implementing Rational Unified Process (RUP) method. There are four phases method, inception phase includes business modeling activities both ongoing processes (as-is) and proposed (to-be). Then from need...

The challenges of information systems (IS) development have changed significantly in the past 15 years. From a situation where the main problem was to build stable systems based on a requirements specification, the IS project manager now faces challenges of integration; for example: how to integrate a new information system into large existing information infrastructures and unstable business p...
