Economic planning in theory and practice

Theory and Practice in Planning

This paper explores opportunities for synergy between theoretical and applied researchers in the area of automated planning. From the diiering perspectives of theorists, experimentalists, and practitioners, we examine the causes of current dissatisfaction with existing theoretical and experimental results. We survey approaches from theoretical computer science that provide alternatives to the s...

A Critical View on New Urbanism Theory in Urban Planning: From Theory to Practice

In the wake of Jacobs’s criticisms of planning, planners increasingly felt a level of angst over, or even responsibility for, the condition of the city. Schooled in preparing and implementing plans and land use regulations, they appreciated the appeal of a new movement that offered a simple, tangible, and marketable recipe for practice. New urbanism theory is one of the contemporary urban theor...

economic optimization and energy consumption in tray dryers

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...

Language Planning: Theory and Practice

Planning with h + in Theory and Practice

Many heuristic estimators for classical planning are based on the so-called delete relaxation, which ignores negative effects of planning operators. Ideally, such heuristics would compute the actual goal distance in the delete relaxation, i. e., the cost of an optimal relaxed plan, denoted by h. However, current delete relaxation heuristics only provide (often inadmissible) estimates to h becau...
