Automated Microwave Antenna Alignment of Base Transceiver Station

Measurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas

Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...

Single Base-station 3D Positioning Method using Ultrasonic Reflections

In context awareness applications the locations of people, devices or objects are often required. Ultrasound technology enables high resolution position measurements indoors. A disadvantage of state-of-the-art ultrasonic systems is that several base stations are required to estimate a 3D position. Since fewer base stations leads to lower cost and easier setup, a novel method is presented that r...

GSM Base Station Subsystem Management Application

The Faculty of Electrical Engineering and Communication of the Brno University of Technology offers several subjects focused on mobile communication networks. For practical exercises the experimental mobile network has been building at our faculty. As we do not have OMC or NMC in our network and as the low level network management is quite complex we designed the software that is useful tool fo...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
