Opis:
Increasing development in information and communication technology leads to the generation of large amount of data from various sources. These collected data from multiple sources grows exponentially and may not be structurally uniform. In general, these are heterogeneous and distributed in multiple databases. Because of large volume, high velocity and variety of data mining knowledge in this environment becomes a big data challenge. Distributed Association Rule Mining(DARM) in these circumstances becomes a tedious task for an effective global Decision Support System(DSS). The DARM algorithms generate a large number of association rules and frequent itemset in the big data environment. In this situation synthesizing highfrequency rules from the big database becomes more challenging. Many algorithms for synthesizing association rule have been proposed in multiple database mining environments. These are facing enormous challenges in terms of high availability, scalability, efficiency, high cost for the storage and processing of large intermediate results and multiple redundant rules. In this paper, we have proposed a model to collect data from multiple sources into a big data storage framework based on HDFS. Secondly, a weighted multi-partitioned method for synthesizing high-frequency rules using MapReduce programming paradigm has been proposed. Experiments have been conducted in a parallel and distributed environment by using commodity hardware. We ensure the efficiency, scalability, high availability and costeffectiveness of our proposed method.

Opis:
The objective of this work was to register and document the traditional knowledge of plant resources used in ethnoveterinary practices in Kendrapara district of Odisha, India. Investigation was carried out in the interior of the district, to explore the therapeutic uses of plants by local inhabitants. Information was gathered from traditional healers, elderly people and farmers by using participant observation, open-ended conversations and semi-structured questionnaires. Plants used as veterinary medicines were collected and identified by botanical classification. Fifty five plant species, distributed among 34 families, were indicated for 27 different medicinal uses. The family Solanaceae had the largest number of reported species followed by Mimosaceae, Fabaceae and Apocynaceae. Prominent diseases treated by plant remedies were wounds, diarrhea, constipation, snake bite, skin ailments and rheumatism. Leaves were more commonly utilized for the preparation of ethnoveterinary medicine than other plant parts. Documentation of traditional knowledge related ethnoveterinary information and identification of potential species for prioritization of conservation through sustainable management is essential for the benefit of future generations. The present study contributed to the construction of an inventory of ethnoveterinary plants, which might provides a better database for future scientific validation studies.

In this paper we deal with a relatively simpler method for the Fourier analysis of EXAFS data and illustrate this by a detailed analysis of the data for cobalt metal foil and cobalt complexes of isoxezol series. The Fourier analysis is useful in extracting distances and information about the phase shifts, the amplitudes, the Debye-Waller factors and the mean free paths. Here we have determined interatomic distances, mean square deviation and inelastic mean free path from the Fourier transform of EXAFS data for cobalt metal foil and cobalt complexes of isoxezol series by Math-CAD programming.

Opis:
Position-based routing protocols are widely accepted efficient solution for routing in MANETs. The main feature of position-based routing protocols is to use greedy forwarding methods to route data. The greedy forwarding methods select a node, either having maximum progress towards destination (distance-based principle) or minimum deviation with line between source and destination (direction-based strategy). The first method minimizes the hopcount in a path and on the other hand, second method minimizes the spatial distance between source and destination. The distance-based routing has a great impact on the selection of reliable node and the direction based routing plays a major role to increase the stability of route towards destination. Therefore, in this paper authors propose a weighted forwarding method, which combines both the selection, schemes to select an optimal next forwarding node in a range. The simulation results show that the proposed scheme performs better than existing position-based routing protocols.

Opis:
With the increasing uses of internet technologies in daily life, vulnerability of personal data/information is also increasing. Performing secure communication over the channel which is insecure has always been a problem because of speedy development of various technologies. Encryption scheme provides secrecy to data by enabling only authorized user to access it. In the proposed paper, we present an encryption algorithm designed for data security based on bilinear mapping and prove it secure by providing its security theoretical proof against adaptive chosen cipher-text attack. With the help of a lemma, we have shown that no polynomially bounded adversary has non-negligible advantage in the challenging game. We also give the comparative analysis of the proposed scheme in terms of security and performance with Deng et al., 2020 and Jiang et al., 2021 schemes and prove that proposed algorithm is more efficient and secure than others existing in literature against adaptive chosen cipher-text attack.

Opis:
Convolutional Neural Network (CNN) is a special type of Artificial Neural Network which takes input in the form of an image. Like Artificial Neural Network they consist of weights that are estimated during training, neurons (activation functions), and an objective (loss function). CNN is finding various applications in image recognition, semantic segmentation, object detection, and localization. The present work deals with the prediction of the welding efficiency of the Friction Stir Welded joints on the basis of microstructure images by carrying out training on 3000 microstructure images and further testing on 300 microstructure images. The loss function decreased for both training and testing set decreased with the increasing number of epochs. The obtained results showed an accuracy of 80 % on the validation dataset.

Opis:
The application of information technology, particularly in health science in the present situation, is provisioned with intelligent applications along with automation to minimize the associated cost and enhancement of the facilities. Although the experimentation associated with the microorganisms may be a part of pathological aspects, it cannot be constrained at one specific location. Yet again, the same may be diversified widely in large geographical locations based on applications and utilities. The inclusion of computational intelligence along with complete advanced technical support is very necessary to overcome these difficulties and support the linked base stations for archiving optimum signals through the deployed sensors. In short, sensors can be used to translate the parametric values of accumulated data into signals which can also be analyzed and monitored. In this work, a specific meta-heuristic technique is implemented, focusing on the accumulation of sensors and the response time for accumulation of data.
Zastosowanie technologii informatycznych, szczególnie w naukach o zdrowiu w obecnej sytuacji, bazuje na inteligentnych aplikacjach wraz z automatyzacją w celu zminimalizowania związanych z tym kosztów i ulepszenia służby zdrowia. Chociaż eksperymenty związane z mikroorganizmami mogą być częścią zagadnień patologicznych, nie można ich ograniczać do jednej konkretnej lokalizacji. Wykorzystanie narzędzi i aplikacji na szerszym obszarze geograficznym może być bardzo zróżnicowane. Zastosowanie inteligencji obliczeniowej wraz z pełnym zaawansowanym wsparciem technicznym wydaje się konieczne, aby przezwyciężyć trudności i wspierać połączone stacje bazowe w celu archiwizacji optymalnych sygnałów za pomocą rozmieszczonych czujników. Czujniki zatem mogą służyć do przekształcania wartości parametrycznych zgromadzonych danych na sygnały, które można również analizować i monitorować. W artykule zaimplementowano specyficzną technikę metaheurystyczną skupiającą się na akumulacji czujników i czasie odpowiedzi na akumulację danych.

Opis:
In literature, varieties of topology and geographical routing protocols have been proposed for routing in the MANETs. It is widely accepted that the geographical routings are a superior decision than topological routings. Majority of geographical routing protocols assume an ideal network model and choose the route that contains minimum number of hops. However, in reality, nodes have limited battery power and wireless links are additionally unreliable, so they may highly affect the routing procedure. Thus, for reliable data transmission, condition of the network such as link quality and residual energy must be considered. This paper aims to propose a novel multi-metric geographical routing protocol that considers both links-quality and energy metric along with progress metric to choose the next optimal node. The progress is determined by utilizing greedy as well as compass routing rather than pure greedy routing schemes. To combine these metrics, fuzzy logics are used to get the optimal result. Further, the protocol deals with “hole” problem and proposes a technique to overcome it. Simulations show that the proposed scheme performs better in terms of the packet delivery ratio, throughput and residual energy than other existing protocols.
