Coastal Bangladesh experiences significant poverty and hazards today and is highly vulnerable to climate and environmental change over the coming decades. Coastal stakeholders are demanding information to assist in the decision making processes, including simulation models to explore how different interventions, under different plausible future socio-economic and environmental scenarios, could ...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
Perkembangan penduduk memicu peningkatan pertanian agar mampu memenuhi kebutuhan pangan. Peningkatan hasil bergantung pada kebijakan cara menyusun pola tanam dalam realita ketersediaan air dan lahan yang semakin terbatas, dapat memberikan maksimal. Aplikasi Cropwat 8.0 adalah bagian dari sistem informasi berbasis komputer (termasuk pengetahuan/manajemen pengetahuan) dipakai untuk mendukung peng...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
in present world, inequality and uncertainty is high in section of agriculture production and food security of a great amount of people in developing countries is not supplied. based on studies of international organizations, about a third of produced food for human consumption in worldwide is lost or wasted. while in developing countries, there is price enhancement, decrease in access to healt...
In Algeria, vegetable crops are dependent on irrigation. this context, the present study is oriented towards efficient management of agricultural water that contributes to improvement crop production. The approach based calculation requirements potato in order control efficiency supply relation requirements. This use imperative for a better yield and healthy environment. study, we used two agro...
The response of the citrus crop to environmental supply largely determines speed and intensity plant's ecophysiological processes, which affect development production crop. main objective was analyze effects climatic conditions on productivity ‘Valencia’ orange agroecosystems (Citrus sinensis L. Osbeck) previously typified in department Meta, Colombia. climatological variables precipitation (PP...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
