An extensive study was conducted to measure the natural gamma radiation (NGR) dose rates for the tin mining areas of Jos Plateau with an objective to establish a reference data record on the levels and distribution of natural background gamma radiation. The measurement was carried out using a portable NaI(Tl) scintillation survey meter. The results obtained, varied significantly for different soil types and for geological features of the study area. NGR dose rates values ranged between 40 nGy h−1 measured on Ferric Luvisols–Ferric Luvisols (S13) soil type, underlain by geological formation G7 (sandstone, clay and shale) and 1265 nGy h−1 recorded on, Haplic Acrisols (S27), underlain by geological formation G8 (Younger granites) with overall mean value of 250 nGy h−1. This is by a factor of four higher than the reported world average value of 59 nGy h−1. Mean indoor and outdoor annual effective dose for the public was estimated to be 1.2 and 0.31 mSv/y, respectively. An isodose map for the distribution and exposure rate due to natural sources radiation for the study area was also plotted using ArcGis software. The data here presented can use to prepare a national radiological map for the country. © 2017, Springer-Verlag Berlin Heidelberg.

This paper deals with the reliability and cost analysis of two unit standby redundant complex system under different repair facility. The system consists of two units' main unit and standby unit connected in standby redundancy. The main units as well as standby unit are assumed to go under two types of failure-partial failure and complete failure. Whenever main unit fails completely, the standby unit takes its load via switch over device. The failed unit goes under repair, if repair facility is available or waits for repair if facility is not available. The system will completely break down if the main unit is under repair and standby unit fails. The failure rates are constant and assumed to follow exponential distribution. Repair follows two types of distribution-general distribution and Gumbel-Hougaard family copula distribution. The system is studied by using supplementary variable technique and Laplace transform. The various measure of reliability has been discussed. Evaluations for some special cases have also been highlighted © 2014 IEEE.

Research is the key to success in any society; technology on the other hand is the fastest vehicle to reach it. As such, for speedy development of any society the two have to be coupled, that is why research and internet cannot be separated. Due to the fact that the internet consists of an ever increasing interconnection of hundreds of millions of computers makes it frustrating to search for information. Even though search engines were invented to solve this problem, one needs to know how to query them in order to find the desired information in the shortest possible time. This is why it is necessary to develop a software that can optimize users query before passing it to a search engine in order to increase efficiency in search results. This paper reports in details how one of such software was successfully developed. © 2014 IEEE.

In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant server before repair of database server, router failure and switch failure. The system can also fail completely due to a cooling failure or some natural calamity like earthquake, fire; etc. All the failure rates are assumed constant while the repairs follow two types of distributions namely general and Gumbel-Hougaard family copula.

Traditional halal slaughter and other forms of religious slaughter are still an issue of debate. Opposing arguments related to pre-slaughter handling, stress and pain associated with restraint, whether the incision is painful or not, and the onset of unconsciousness have been put forward, but no consensus has been achieved. There is a need to strike a balance between halal bleeding in the light of science and animal welfare. There is a paucity of scientific data with respect to animal welfare, particularly the use of restraining devices, animal handling, and efficient halal bleeding. However, this review found that competent handling of animals, proper use of restraining devices, and the efficient bleeding process that follows halal slaughter maintains meat eating quality. In conclusion, halal bleeding, when carried out in accordance with recommended animal welfare procedures, will not only maintain the quality and wholesomeness of meat but could also potentially reduce suffering and pain. Maintained meat quality increases consumer satisfaction and food safety.

In genome sequence alignment problem, a reference string and number of query strings referred as short reads, are given, goal is to seek out occurrences of these query strings in the reference string. Huge amount of reads generated by new sequencing technologies (Illumina/Solexa) need the development of an efficient algorithm requiring both less memory and computational time. There are number of indexing and string matching techniques to align short reads on reference string (genome). Size of index of the reference string in each of existing techniques is large. In this paper, a new self compressed index technique (BWT-WT) is proposed. BWT-WT scheme is based on Burrow Wheeler Transform (BWT) and Wavelet tree (WT). BWT-WT also supports exact alignment of DNA sequence reads. Performances of BWT-WT with other BWT based tools of short read alignments are compared. Experiments show that BWT-WT based program achieves more compression and also faster searching in comparison to other existing tools. © 2015 IEEE.

Two strings P[1⋯m] and T[1⋯n] with m ≤ n, are said to be parameterized match (p-match), if one can be transformed into the other via some bijective mapping. It is mainly used in software maintenance, plagiarism detection and detecting isomorphism in a graph. In the compressed parameterized matching problem, our task is to find all the parameterized occurrences of a pattern in the compressed text, without decompressing it. Compressing the text before matching reduces the size and minimizes the matching time also. In this paper, we mainly focus on the parameterized word matching on the compressed text, where both patterns and text are compressed before actual matching is performed. For compressing the pattern and text, we use efficient compression code: Word Based Tagged Code (WBTC). Experimental results show that our algorithm is up to three times faster than the search on uncompressed text. © 2014 IEEE.

This paper considers the effect of induced magnetic field on transient hydromagnetic natural convection flow of an incompressible viscous electrically conducting fluid in the presence of transverse magnetic field in a vertical channel formed by electrically non-conducting infinite vertical parallel plates due to symmetric heating of vertical parallel plates. The problem is solved using Laplace transform technique and the inversion of the Laplace domain to the time domain is obtained by Riemann-sum approximation method. In order to verify the accuracy of Riemann-sum approximation method, analytical solution for steady state mathematical model is obtained in closed form. The governing equations are also solved using an implicit finite difference method to confirm the method used in the present problem. During the course of numerical computation an excellent agreement was found between steady state solution obtained exactly and transient solution obtained by implicit finite difference method or Riemann sum approximation method at large values of time. The dimensionless parameters in the flow are extensively discussed with the help of graphs. © 2013 The Physical Society of Japan.

Palindrome pattern matching is a classical and well-studied problem in computer science. A palindrome is a string that reads the same forward and backward. Gapped palindrome is an interesting version of the palindrome which is defined as the one having a space between left and right palindromic arms of the string. In this paper, we develop efficient algorithms to detect two different classes of gapped palindromes: long armed and length constrained in a biological sequences by using inverted suffix array. The algorithms perform the computation in O(n) time. Also, we determine palindromic weights (number and size of gapped palindromes) in the input biological string. © 2015 IEEE.

Searching set of patterns {P1, P2, P3,....Pr}, r≥1, inside body of a text T[1...n] is called multi-pattern matching problem. This matching is said to be parameterized match (p-match), if one can be transformed into the other via some bijective mapping. It is mainly used in software maintenance, plagiarism detection and detecting isomorphism in a graph. In the compressed parameterized matching problem, our task is to find all the parameterized occurrences of a pattern (set of patterns) in the compressed text, without decompressing it. Compressing the text before matching reduces the size and minimizes the matching time also. In this paper, we develop an efficient algorithm for parameterized multi-word matching problem on the compressed text, where both patterns and text are compressed before actual matching is performed and pattern is treated as word. For compressing the pattern and text, we use efficient compression code: Word Based Tagged Code (WBTC) and bit-parallel algorithm is used for searching purpose. Experimental results show that our algorithm is up to three times faster than the search on the uncompressed text. © 2014 IEEE.
