تم تصميم نظام قطع جديد لتحسين أداء و انتاجية قصّاصة النباتات المحمولة و لاستخدامها في البيئة القاسية ذات الحشائش القصبية و الكثيفة بكفاءة و جودة عاليين و بأدنى احتياجات للطاقة و في قطع بعض المحاصيل التي تزرع في مساحات صغيرة. النظام الجديد يشمل ثلاثة أنماط: سلاسل بسيطة, سلاسل ذات شفرات مستقيمة و سلاسل بشفرات مائلة, كل سلسلة محمولة على قرص مركزي من الألمنيوم. تم اختبار السلاسل على الشّد, و كانت النتائج مرضية. اختُبرَت الأسلحة حقلياً على أربعة أنواع من السوق النباتية القمح, الذرة الصفراء حشيشة الفرس و الحلفا. قوة القص, الانتاجية, معدل استهلاك الوقود, و احتياجات الطاقة تم تحديدها و عند سرعات مختلفة للدوران, كانت السلاسل ذات الشفرات المستقيمة الأفضل في جودة القطع و أقل احتياجاً للطاقة عند قطع كل من الذرة الصفراء و حشيشة الفرس, كانت السلاسل ذات الشفرات المائلة أفضل بالنسبة لكل من القمح و الحلفا, كانت احتياجات الطاقة و قوى القطع أكبر ما يمكن عند استخدام السلاسل البسيطة. بشكل عام وجد إنه يمكن استخدام هذه الأسلحة بقصاصة النباتات المحمولة و بكفاءة أعلى من التصاميم القديمة.
A new system was designed in portable plants-eater to improve the performance and productivity and for using it in the harsh environment containing like-cane dense brushes with high efficiency, quality and lowest power requirement and to harvest some crops are grown in small areas. The new system includes three types: link chain, straight blades chain and oblique blades chain, each chain is fixed on central aluminum disk. the three chains were tested on tensile, the results were satisfactory. The cutters was tested in the field on four types of stalk Wheat, Yellow Maize, Sorghum Helpenese and imperata cylindrical. Cutting force, productivity, fuel consumption, power requirement was calculated with deferent rotation speeds. The straight blades chain has the best cutting quality and lowest energy requirement on maize and sorghum halepense, the oblique blades chain was better on wheat and imperata cylindrical. The greatest values of energy requirement and cutting forces appeared with link chain cutter-head. In general, these cutter-heads are useable in weed-eater with higher efficiency than the old designs.

Most robotic industries depend on using (servo motors) and (stepper
motors) orcontinuous current motors (DC motors) for movement
transition, which increases the cost and complicates the robot’s
controlling process, as well as its driving circuits.
This essay deals with using pneumatic in the new design and
building of a robot’s arm, that can manage to do many tasks with a
much lower budget than the one needed for any of the above
mentioned methods, that’s because it can be used for tasks that need
high speed and capacity, but don’t need precision.
This research to talk about, After-shocks is known (Label affixed, wildcard, kindness, emphasis, the kindness of the statement) be conducted in accordance with in terms of expression and in the link meanings with each other, but if you mentioned qual
ities praise or slander and some of express moral purpose or rhetorical or to draw attention ... called it certainly , but this is a rhetorical significance of the increased interest in the matter.
However, the speaker rhetorician may be amended for this link between the disciples for the purpose of moral, it is definitely after a certain methods and the commands and prohibitions, and wishful thinking, and Esperance, and pray, presentation, and question and penalty .... and all this for the purposes of moral used by the speaker, eloquent in these methods, so I worked on that show and a statement that the pieces do not fall after the well-known disciples: (label affixed, wildcard, kindness, emphasis, the kindness of the statement) only, but can be located in other methods of science of language and rhetoric.
The purpose of this research is to enhance fractional numbers precision
according to the new representation of fractional numbers, adding some extra
cost to the hardware so we suggest a new number system per representing of
fractional numbers in c
omputers, that depends on the series
With mathematical, algorithmic study, and its hardware of our research, we
consider the two principal formats of real numbers in computers: fixed- point,
floating- point and the cost of the hardware required to store and process the
numbers.
Due to scientific and technical advances in industrial electronics, SRMs have become one of the most attractive motors in recent decades.
This muscle has
been used to design a robot arm similar to that of the humerus and
forearm, which can attract large objects with a weight of up to 500
N, which is equivalent to a professional bodybuilder raising his
weight.
