in this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. the stages for prey have been considered. the proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. the model is analyzed by using linear stability analysis to ob...

UNLABELLED A hypothetical protein is predicted to be expressed from an open reading frame without known experimental evidence of translation. They constitute a substantial fraction of proteomes. Domain extraction from these hypothetical sequences helps to search for protein coding genes for protein structural and functional annotation. We describe the analysis of prediction data in a sequence d...

in this study, liquid-liquid extraction process in a kuhni extraction column was modeled and simulated. a non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. the model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. the population balance model was used ...

this paper aims to investigate the effect of budget deficit shock on government spending in indonesia. for this propose, this reasearch uses an alternative error correction model based on loss function of government spending. the model assumes the short run disequilibrium, in which shock variables may play an important role. a spesific loss function model is applied to develop the long run gove...

7 Abstract 8 An existing materials flow model is adapted (using ExcelTM and AMBERTM model platforms) 9 to account for waste and hidden material flows within a domestic environment. Supported by 10 national waste data, the implications of legislative change, domestic resource depletion and 11 waste technology advances are explored. The revised methodology offers additional 12 functionality for e...

We present a method for retrieving concepts from web search queries and from candidate documents on the web, to help determine which of these documents are semantically (rather than simply keyword wise) related to the query. Our method combines hypothetical reasoning, which we use both for natural language analysis and for concept extraction, and domain-oriented taxonomies of concepts to guide ...
