Mining Frequent Itemsets Using Genetic Algorithm
In general frequent itemsets are generated from large data sets by applying
association rule mining algorithms like Apriori, Partition, Pincer-Search,
Incremental, Border algorithm etc., which take too much computer time to
compute all the frequent itemsets. By using Genetic Algorithm (GA) we can
improve the scenario. The major advantage of using GA in the discovery of
frequent itemsets is that they perform global search and its time complexity is
less compared to other algorithms as the genetic algorithm is based on the
greedy approach. The main aim of this paper is to find all the frequent
itemsets from given data sets using genetic algorithm
Training a Feed-forward Neural Network with Artificial Bee Colony Based Backpropagation Method
Back-propagation algorithm is one of the most widely used and popular
techniques to optimize the feed forward neural network training. Nature
inspired meta-heuristic algorithms also provide derivative-free solution to
optimize complex problem. Artificial bee colony algorithm is a nature inspired
meta-heuristic algorithm, mimicking the foraging or food source searching
behaviour of bees in a bee colony and this algorithm is implemented in several
applications for an improved optimized outcome. The proposed method in this
paper includes an improved artificial bee colony algorithm based
back-propagation neural network training method for fast and improved
convergence rate of the hybrid neural network learning method. The result is
analysed with the genetic algorithm based back-propagation method, and it is
another hybridized procedure of its kind. Analysis is performed over standard
data sets, reflecting the light of efficiency of proposed method in terms of
convergence speed and rate.Comment: 14 Pages, 11 figure
Role of SHG Movement on Feminization of Living- A Grassroot Study on Economy of Sunderban
Feminization is an identity of women. A society is composed of two economic genders - man & woman. The flagship program of union government of India, Swarnajayanti Swarojgar Yojana has infected the community to be attached with the money earning procedures by linking with Self Help Groups (SHGs). Indian Sunderban is a totality of some islands; people who are residents of those lands are facing a lot of challenges and conflicts. Naturally the women are under threat of several types here so the study empirically wants to know if any change regarding livelihood is promoted on the region by the women or if any advantage if they are getting.

Failure of intrauterine contraception in a multigravida lady with an undiagnosed uterus didelphys: a case report
Uterus didelphys remains one of the rarest uterine anomalies partly because; majority women experience no symptoms with an uneventful reproductive life. Despite the cost-effectiveness and efficacy paired with fewer side effects and convenience of using an intrauterine contraceptive device, it is most likely to prove futile in an unsuspected case of didelphic uterus resulting in an unintended pregnancy. Hence, intrauterine contraception is generally considered a contraindication in cases of uterine malformations. We present a case of a multigravida mother (G7 P3 L3 A3) with a history of three term vaginal deliveries, with an undiagnosed uterus didelphys, carrying a single live intrauterine pregnancy of approximately 6 weeks period of gestation, in the right uterine horn and a copper containing intrauterine contraceptive device in the left uterine horn, willing to undergo medical termination of pregnancy. A high index of suspicion, on the part of the gynaecologist as well as the radiologist, is required to investigate concurrent pregnancy with a history of an intrauterine contraceptive device insertion, in order to rule out rarer uterine malformations like uterus didelphys. Thorough history taking and clinical examination accompanied by improved imaging techniques should be performed at the time of first pregnancy in order to avoid an unsuitable placement of an intrauterine contraceptive device
A new (k,n) verifiable secret image sharing scheme (VSISS)
AbstractIn this paper, a new (k,n) verifiable secret image sharing scheme (VSISS) is proposed in which third order LFSR (linear-feedback shift register)-based public key cryptosystem is applied for the cheating prevention and preview before decryption. In the proposed scheme the secret image is first partitioned into several non-overlapping blocks of k pixels. Every k pixel is then used to form m=⌈k/4⌉+1 pixels of one encrypted share. The original secret image can be reconstructed by gathering any k or more encrypted shared images. The experimental results show that the proposed VSISS is an efficient and safe method
Morphological, structural and electrical properties of polypyrrole nanocoated bamboo cellulose fibre
Bamboo cellulose fibres have been coated with polypyrrole and the coated fibres are then characterized for various properties. The changes in surface morphology and particle distribution are studied by scanning and transmission electron microscopy which indicate the formation of nano-coating of polypyrrole over the fibre surface, as the average diameter of the particles forming the surface layer is found 50 nm. Fourier transform infrared spectroscopy reveals that the chemical structure of the natural fibres remains unchanged even after the nano coating, though the individual characteristics of pyrrole appears therein. Electrical resistance of the coated fibres, measured by two probe method, shows decreasing trend with increasing pyrrole concentration. The value ranges from 1075 KΩ cm-1 to 0.159 KΩ cm-1 from 0.1% to 5% pyrrole. Further, it shows Ohmic nature for both the coated and uncoated fibres. Dielectric behavior of the current-voltage (I-V) plots of the coated fibres exhibits highly dispersive dielectric loss and similar behavior in its AC conductance, at low frequency range up to 7 kHz; beyond which its conductance is stabilized
