A note on absolute summability factor theorem and almost increasing sequences

  Quite recently Savas (2008) has proved a theorem on- summability factors of an infinite series. The present paper deals  with a further generalization of it.   Key words: Absolute summability, almost increasing, weighted mean matrix, summability factor.

Field-Programmable Gate Array (FPGA) Implementation of Lapped Biorthogonal Transform for JPEG XR Compression

  This paper describes the hardware implementation of Lapped Biorthogonal Transform (LBT) on Field-Programmable Gate Array (FPGA) for JPEG XR Image compression. The implementation is based on dividing image into 128×128 dimension tiles with each tile processed independently. Two main operations that is, overlap pre-filtering and forward core transform are applied on each tile. The proposed...

Diversity and abundance of insect species at Kota Damansara Community Forest Reserve, Selangor

  A study was conducted on the diversity and abundance of insect species at Kota Damansara Community Forest Reserve in order to determine the richness of the forest insect fauna. A total of 774 insects from 13 Orders and 79 Families were recorded. This study shows that Coleoptera (42.63%), Hymenoptera (17.96%), Diptera (10.08%) and Orthoptera (10.85%) were the most dominant Orders in the Forest Reserve. The...

Determination of the relative abundance and distribution of bacteria and fungi in Bonny light crude oil-contaminated sandy loam soil

  This study was undertaken to investigate the effects of Bonny light crude oil (specific gravity = 0.81; API gravity 43.20) on the numerical composition of soil bacteria and fungi and relative distribution of Gram positive and Gram negative soil bacteria. Eight different levels of the crude oil (0.5, 1.0, 2.0, 2.5, 5.0, 10.0, 15.0 or 20.0% v/w of soil) were used for the controlled pollution of soil samples...
