Continuous and discrete modeling of HIV-1 decline on therapy

Modeling Discrete and Continuous Processes

by Magne Myrtveit Normally, we try to aggregate discreteness in System Dynamics (SD) models by making continuous flows. This is a good modeling practice, but in some cases discreteness may have a significant influence on system behavior (see note). Consequently, we need to model such discreteness to explore its impact on behavior. The System Dynamics (SD) technology was originally designed with...

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

Modeling Languages for Continuous and Discrete Systems

Recent Advances in Discrete and Discrete- Continuous Modeling Systems

This chapter discusses the importance of discrete choice and discrete-continuous modeling methods in the cost-benefit evaluation of transportation infrastructure improvement and other related projects. Specifically, discrete choice and discrete-continuous methods constitute the backbone of travel demand models that are used to predict travel characteristics and usage of transportation services ...

Modeling of Event-Driven Continuous-Discrete Processes

Models of industrial processes often contain discrete phenomena superimposed on the continuous system behavior. Simulation of batch processes, start-up and shutdown procedures, fault diagnosis and alarms fall under this category. Models for such processes require a mathematical theory for both its continuous and discrete state transitions. A key problem in hybrid simulation lies in the detectio...
