From biological models to economic optimization.
This article addresses the additional challenges being faced when biological models are used as a basis for decision support in livestock herds. The challenges include dealing with uncertain information, observation costs, herd dynamics and methodological issues in relation to the computational methods applied particularly in the dynamic case. The desired key property of information included in...
متن کاملInvestigation of Biological and Economic Changes in Herd of Dairy Cows Using Optimization Models
The aim of this study was to identify the factors affecting the culling of dairy cows and their impact on reproductive performance and costs of the herd so that optimal decisions can be made in replacing dairy cows and thereby increase the annual income of dairy cattle. For this purpose, data collected from four active cattle breeding units in Ardabil province (including biological parameters a...

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
15 صفحه اولToward efficient riparian restoration: integrating economic, physical, and biological models.
This paper integrates economic, biological, and physical models to explore the efficient combination and spatial allocation of conservation efforts to protect water quality and increase salmonid populations in the Grande Ronde basin, Oregon. We focus on the effects of shade on water temperatures and the subsequent impacts on endangered juvenile salmonid populations. The integrated modeling syst...
متن کاملIntroduction to Biological Models
The ocean is inhabited by innumerable individuals of many different genera and species, each having its own developmental/physiological state and each being immersed in its own environment. The organisms move, both because of water flow and because of their own swimming or buoyancy, and interact with their environment by gathering resources which they need and by excreting waste products. The a...
