comparison of three conventional rice combine harvesters in mazandaran, iran
two types of paddy combine harvester (head-feed and whole-crop) are commonly available in different widths in developed countries. the use of combine harvesters can greatly decrease labor costs and efficiency. combine harvesters have been introduced in several east asian countries (china, japan, south korea) to decrease costs, but their technical and economic performance has not yet been studie...
متن کاملDesign of a Smart Mass Flow Sensor for Combine Harvesters
A popular method for measuring mass flows on combine harvesters is to register the induced force on a circular chute. Since this type of sensors are strongly subjected to wear and installed on difficult accessible places, it is important to know when the sensor provides wrong measurements without interrupting the process. In this study, a double, adaptive IIR notch filter is designed to track b...
متن کاملLarge-scale ultrasonic cleaning system: Design of a multi-transducer device for boat cleaning (20kHz).
The present study is part of a global project which consists in the development of an automatic cleaning station for immersed boats (cockle, ninepin, etc.) in a self-service mode, associating an innovative ultrasonic device for cleaning with a specific water treatment. The originality of the process is that cleaning is performed by three transducers operating simultaneously at low frequency and...
متن کاملOptimisation : A case study of utilising teachingspace
This paper presents an approach to distributed optimisation applied to the problem of teaching space utilisation in a college. We describe the basic ingredients of the problem and analyse various solutions, some produced in a centralised environment and some in a distributed environment. The main aim is to investigate how distributed optimisation may be formulated. In particular we introduce a ...
متن کاملtight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
