growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
Design of a Multiplier for Similar Base Numbers Without Converting Base Using a Data Oriented Memory
One the challenging in hardware performance is to designing a high speed calculating unit. The higher of calculations speeds in a computer system will be pointed out in terms of performance. As a result, designing a high speed calculating unit is of utmost importance. In this paper, we start design whit this knowledge that one multiplier made of several adder and one divider made of several su...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
this study was designed to investigate the effects of different levels of tarragon powder on general performance and anetometric, properties of digestive system of male broiler chickens. 200 one-day-old ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. experimental diets were set on the bas...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
regarding to rapidly changing and highly competitive business environment it will become increasingly important for organizations to measure their performances appropriately. with respect to special characteristics of pharmaceutical industry and lack of reported performance measurement, this study tries to design an integrated performance measurement model for pharmaceutical companies. for gene...
according to iranian code of practice for seismic resistant design of buildings standard no. 2800, yazd is located in the place with the medium earthquake hazard [1]. due to the position of yazd with many historical and important buildings, maintaining these traditional heritages is an important task in civil engineering field. on account of these mentioned valuable buildings and region potenti...
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
درعلم مهندسی سازه و زلزله با ورود و جایگزینی شیوه طراحی بر اساس عملکرد(performance base design) به جای روش قدیمی طراحی بر اساس نیرو بسیاری از آئین نامه های جهان دستخوش تغییرات بنیادی شده و بسیاری از محققان و پژوهشگران برای تکامل و دستیابی به قطعیت در این شیوه، تحقیقات خود را در این زمینه متمرکز کرده اند. طراحی براساس عملکرد موضوعی است که در سال های اخیر در سطح جهان و کشورما مورد استقبال فراوان ...
this research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and nox in di diesel engines. since the most important engine design parameters, includi...
