In recent years, high-speed wireless communication is in vogue. In wireless communication systems, multipath fading, delay and interferenc occurres by reflection or diffraction. In a high-speed wireless communication, it becomes a necessary to separate desired signal from delay or interference signal. Thus to overcome these problems Smart antenna systems have been developed. Basically there are...

This paper presents the application of a connectionist control-learning system to autonomous mini-robots. These robots are specially designed and equipped for learning easily deened yet challenging control tasks. The system must learn despite noisy, low-grain sensory input and uncertain interactions between motor commands and eeects in the world. The system's design is severely constrained by t...

The Marchand balun has larger bandwidth than other types of combiners and has been used extensively since its introduction. The Marchand balun has also been extensively used in planar systems in both broadside-coupled and edged-coupled configurations. This paper describes the design and development of two microstrip, folded, edge-coupled Marchand baluns for use as anti-phase power combiner. The...

A sonnet poem, typically consisting of a thesis, an antithesis, and conclusion, is dynamic entity by its very nature. In the sonnets Lesia Ukrainka, various aspects such dynamics can be observed at both proper textual intertextual levels. At level, important role in dynamization text system primarily played numerous lexical syntactic repetitions. While tradition has long prevented use repetitio...
