DMT modulation has become a standard communications method for DSL and indoor LAN technology. By utilising the FFT it is able to overcome the problems associated with transmission over a nonflat communications channel. In DSL and indoor LAN technologies, the dominant source of performance impairment is crosstalk. Results are presented here in the context of DMT on an economical cabling scheme w...

Unlike old-fashioned aircrafts that almost did not have avionics systems, up to date aircrafts have numerous avionics systems. Nearly all new aircrafts have devices for navigation, automatic flight control, collision avoidance systems, flight data recorder, weather radar system in addition to communication and monitoring systems. All of these devices employ embedded computer systems with growin...

To provide keyword-based access to a large text file it is usually necessary to invert the file and create an inverted index that storeso for each word in the file, the paragraph or sentence numbers in which that word occurs. Inverting alarge file using traditional techniques may take as much temporary disk space as is occupied by the file itself, and consume a great deal of cpu time. Here we d...

In the past decade, the wireless industry has undergone a metamorphosis. This industry has turned from a predominantly military driven market to a cost conscious, consumer driven commercial market. At the same time, the wireless applications are moving up in the frequency spectrum. A typical example would be the PCS system. The PCS systems are currently designed for 1.9 GHz spectrum, but the ne...

Paddy-Fish integrated system has been applied by Indonesian farmers. They practiced diversification farming in correlation to get more benefit and minimized risk. The objective of this research was analyse technical economical feasibility paddy-fish at lowland rice field. This used the experimental field method. Fish pond created surrounded with 3 m width 0,5 depth where fish grown for 4 months...
