A Short Survey of Data Compression Techniques for Column Oriented Databases
Abstract: AbstractColumn oriented data-stores has all values of a single column stored as a row followed by all values of the next column. Such way of storing records helps in data compression since values of the same column are of the similar type and may repeat. This paper surveys the various data compression techniques in column oriented databases. Data compression is efficiently used to save storage space and network bandwidth. It …

Design of Triple Band Microstrip Yagi Uda Antenna
Abstract: Abstract A microstrip yagi uda antenna with triple band is proposed in this paper. The design antenna consists of CPW feeding in which the ground plane and the yagi antenna are on the same plane. The resonating frequency of design antenna is 6.29, 7.97 and 9.26 GHz. The antenna had achieved the directivity of 5.232, 5.704 and 6.062 dBi. The impedance of antenna is completely matched at all the three …
