Productivity and cost of conventional understory biomass harvesting systems
Conventional harvesting equipment was tested for removing forest understory biomass (energywood) for use as fuel. Two types of systems were tested a one-pass system and a two-pass system. In the one-pass system, the energywood and pulpwood were harvested simultaneously. In the two-pass system, the energywood was harvested in a first pass through the stand, and the pulpwood was harvested iris se...
متن کاملthe impact of computer-assisted language learning on achievement motivation of high school students
چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...
Computer-Assisted Technologies in Medical Decision Making
The practice of medicine has evolved rapidly of the last 50 years. Due to these advances, the number of parameters that are presented to the medical professional have expanded beyond the capacity for complete analysis by healthcare professionals. Medical data is complex and includes a number of different representations including written notes, numeral data, and images. An automated analysis mu...
متن کاملNitrogen Fertilization Effects on Biomass Production and Yield Components of Miscanthus ×giganteus
Grasses such as Miscanthus ×giganteus and Panicum virgatum (switchgrass) can potentially be used to produce bioenergy on a large scale in the Midwestern USA. The biomass productivity of these warm-season perennial grasses, particularly M. × giganteus, can be substantial, even when grown with limited inputs. The literature, however, varies regarding the nitrogen requirements for M. ×giganteus bi...
متن کاملEstimation of cost efficiency for firms in different technologies using data envelopment analysis
Data envelopment analysis (DEA) is a method for evaluating the relative efficiency of a set of firms in a production process. Estimation of cost efficiency is one of the branches of performance evaluation. Cost efficiency evaluates the ability of producing current output with minimum available cost. Now let's assume that there are several groups of firms that operate separately and have differe...
