Investigations using data from LANDSAT-2

The author has identified the following significant results. New lands for forestation were set aside in the coastal area of Bangladesh, based on LANDSAT mosaics (Chittagong - 195,000 acres, Noakhali - 450,000 acres, Barisal - 360,000 acres, and Patuakhali - 225,000 acres). LANDSAT imageries were used for identification of drainage patterns in both the old and and new Comilla district

Investigations using data from LANDSAT-2

The author has identified the following significant results.Preliminary land use maps of Sunamgonj, Baniachong, and Srimongal areas in the Sylhet districts were prepared. Indication of new land in the southern Patuakhali district and Hatiya Island were found, and erosion in northern Hatiya Island is also indicated

Investigations using data from LANDSAT-2

The author has identified the following significant results. A land use map was prepared of Dacca-Narayanganj-Demra area on a scale of 1:50,000. LANDSAT imageries of Dinajpur and Rangpur districts were studied. The difference between the exposed Pleistocene red clay, this clay under alluvial cover, and recent alluvium were noted. Different types of soils, crops, etc. were delineated on the ERTS imagery

A Low Cost Two-Tier Architecture Model For High Availability Clusters Application Load Balancing

This article proposes a design and implementation of a low cost two-tier architecture model for high availability cluster combined with load-balancing and shared storage technology to achieve desired scale of three-tier architecture for application load balancing e.g. web servers. The research work proposes a design that physically omits Network File System (NFS) server nodes and implements NFS server functionalities within the cluster nodes, through Red Hat Cluster Suite (RHCS) with High Availability (HA) proxy load balancing technologies. In order to achieve a low-cost implementation in terms of investment in hardware and computing solutions, the proposed architecture will be beneficial. This system intends to provide steady service despite any system components fails due to uncertainly such as network system, storage and applications.Comment: Load balancing, high availability cluster, web server cluster
