Irrigation Uniformity with Complete Fluidic Sprinkler in no-wind conditions

The Complete fluidic sprinkler was originally created by China. Irrigation uniformity in no-wind conditions was studied in this paper. Radial water distribution for complete fluidic sprinkler type 10 was got by experiment. MATLAB was used to establish computation program to change the radial data into net data. Three-dimensional water distribution figures for single sprinkler and combined sprin...

Uniformity is Weaker than Semi-Uniformity for Some Membrane Systems

We investigate computing models that are presented as families of finite computing devices with a uniformity condition on the entire family. Examples of such models include Boolean circuits, membrane systems, DNA computers, chemical reaction networks and tile assembly systems, and there are many others. However, in such models there are actually two distinct kinds of uniformity condition. The f...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Assessing SALTMED model for wheat experiments irrigated with basin and sprinkler systems

Comprehensive agricultural models are crucial for assisting several decision makingprocesses due to their capability for use under different conditions. SALTMED is a holisticgeneric model, which simulates yield, dry matter and soil water content under differentirrigation managements and systems. The aim of this study was to calibrate the SALTMEDmodel to simulate wheat yield, dry matter and soil...

Portable calibration systems for robots

In recent years both the attainable accuracy in terms of repeatability and the accuracy requirements for robots have increased. The more stringent requirements in terms of accuracy stem, e.g., from the advent of off-line programming techniques, which can only be used if the robot’s positioning can be predicted with sufficient accuracy. It is, therefore, necessary to maintain this accuracy. This...
