abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
adolescents and young adults and their problems is an issue whose importance is obvious to anyone because youth are the founders of our countrys future and requires proper planning to be on leisure. given the importance of leisure,this study to investigate needs assessment and planning how adolescents and young adults spend their leisure time in urban of case study of high school girls and boys...
A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...
In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high a...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
The action systems framework supporting formal circuit derivations has been successfully applied to synchronous VLSI design. The present paper presents a C++ application that translates descriptions of synchronous action systems into VHDL code, after their formal transformation from the initial high-level specifications into concrete enough format. After the automatic conversion, the resulting ...
در آخرین گزارش (jnc)joint of national committee فشار خون سیستولیک بین 139-130 میلی متر جیوه و فشارخون دیاستولیک بین 89-85 متر جیوه بعنوان فشارخون high-normal معرفی شده است. در مطالعات مختلف نشان داده شده است که این مرز از فشار خون در طولانی مدت بر سلامت افراد تاثیر دارد و یکی از مهمترین پیش زمینه های ابتلا به هیپرتانسیون می باشد. مطالعه حاضر با هدف تعیین شیوع و مشخص کردن سایر پارامترهای...
Signiicant power reduction can be obtained in the datapath of a CMOS VLSI circuit if data characteristics are carefully exploited. An improved approach that achieves such reduction by using a new model relating important data characteristics to the transition activity in static CMOS circuits is presented. Speciically, relationships between xed-point, two's complement data and 0 ! 1 transition a...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
