Locating sites of high discharging wells in metamorphic crystalline terrain is still a difficult problem imposing inadequate protection and management for groundwater resources. The present study attempts to determine this technique in a Precambrian metamorphic rock in and around Balarampur, Purulia district, West Bengal, India using lineaments, joints/fractures and well data with the help of software approach. The joints/fracture study consists of using hydraulically significant fracture data to generate representative modal and coefficient of variance (Cv) for each domain. Lineament study incorporates estimation of the hydraulically significant FCL and their percentage of occurrence in each domain. The hydrostructural domain based study identifies areas within the shear zone (D2) and south of the shear zone (D3) as hydraulically significant region than the region to north of the shear zone (D1). The modal and Cv values of well discharges also signify D2 and D3 as hydraulically significant part of the study area. Existing wells show discrete increase in discharge from Dl. to D3 through D2, with high discharging wells (= 4000 litre per day) occurring in groups in linear fashion, defining 'well lines', in close proximity to the determined FCL. Thus the study validated the hydrostructural domain based analysis for locating high discharging wells, indicating the sites for protection and management of groundwater resources for sustainable utilization and development in Precambrian metamorphic terrain.Keywords

Background/Objectives: In the biological sequences, palindromes can create structures that differ from the common structure of non-palindromic sequences. Unfortunately, mutations introduced by evolutionary methods, make it difficult to search the palindromes in DNA sequences. Methods/Statistical Analysis: The mutations occur in DNA sequences with spacer (i.e. set of characters). One version of such algorithms has been intended to search for palindromes with gaps (i.e. spacer) - gapped palindromes. The concept of Dynamic Suffix Array (DSA) is used to propose algorithms to search two classes of gapped palindromes-length constrained and long armed. DSA modifies the previous built suffix arrays when there is insertion and deletion of a new character, due to which efficiency is improved. DNA datasets obtained from National Centre for Biotechnology Information (NCBI) is taken as input. The execution time, palindrome weight and length of palindrome arms and spacer are analysed. Findings: Our proposed algorithms search maximal length constrained and long armed gapped palindromes in DNA sequences efficiently. Time complexity of our proposed algorithms is O(n), where n is input parameters. Also, we compute palindrome weights in the DNA sequences. For length constrained gapped palindromes, our proposed algorithm is compared with existing one. The existing algorithm uses only suffix array. Experimental Observations reveal that by the use of DSA, execution time of our algorithm on different DNA sequences has been improved by maximum 57.89%. It also shows a decrease in the execution time over existing approach, proving our designed algorithm is space efficient, faster and easy to implement. Applications/Improvement: Our algorithms analyze short DNA sequences easily. These algorithms can be executed and tested on standard DNA and datasets with large number of base pairs.Keywords
