The Information and Communication Technology (ICT) sector, for its potential to generate huge economic and social development, has been the buzzword for all the business discussions and research in last two decades. In this paper, the authors have analyzed the growth rate of the Internet in terms of active and passive users in a global scenario. The data from various internet research organizations has been consolidated and used to deduce that the penetration of Internet, in the developed as well as developing economies of the world, is consistently increasing. As the number of users of the Internet increases, it would either have a positive or a negative impact on the economy of the country. The direction and extent of the effect has been studied in this paper.Keywords

In the eastern India, rainfed area occupies nearly two-third of its total cultivable area. Rice is the predominant crop which is no more beneficial to farmers of the region due to its low yield. So there is a need to change in a cropping system and to find better crop substitution which can give more returns to the farmers than the existing system. With this view, the study was conducted at Indian Institute of Technology Kharagpur to evaluate rice and sweetcorn based cropping system for rainfed upland ecosystem of Eastern India. For this purpose two cropping systems, rice-peanut and sweetcorn-peanut were taken into consideration. Two crop growth simulation models viz., CERES-rice and CERES-maize of DSSAT v4.0 (Decision Support System for Agrotechnology Transfer) were used to simulate the rice and maize yield of the region using historical weather data at Indian Institute of Technology Kharagpur for the years 1978 to 2007. The field experiment was carried out and the experimental data of yield components (yield and top weight) for the years 2009 to 2011 were used to calibrate and validate both the models. The comparative assessment of economic feasibility of the cropping systems (rice-peanut and sweetcorn-peanut) was also carried out to identify suitable cropping system for the region. The results of the models validated statistically which revealed that the models can predict the yield components with high accuracy. The net income from 1 hectare for rice-peanut and sweetcorn-peanut cropping pattern was Rs. 64415 and Rs. 90330, respectively. So it was concluded from the study that, for the rainfed upland ecosystem of Eastern India, sweetcornpeanut cropping system was more beneficial than rice-peanut cropping system. Sweetcorn-peanut cropping system can be adopted for the sustainable development in the region.Keywords

Ganga River Basin (GRB) is the second most populous river basin in the world, which has been undergoing rapid land-use change during the last few decades. Here, we analyse the landscape dynamics in Indian GRB (IGRB) using three indices, i.e. class area, mean patch size and number of patches for 14 land-use and land-cover (LULC) classes using multi-temporal Landsat satellite datasets of 1975 and 2010. Major change was observed with the expansion of agricultural lands and human settlements and depletion of forests. Agricultural lands covered the highest area (>75%), where low to medium-sized patches have increased and patches with larger size have been slightly reduced in size over past decades. The highest increase in percentage of built-up land has been appropriately captured on medium-resolution satellite imageries using visual interpretation technique. Degradation and loss of forest areas were reported in terms of landscape indices; however, the increase of plantation is a positive sign in the basin. In general, we observed aggregation of agricultural patches and reduction of forest patches in small to medium patch sizes. We argue the utility of 'onscreen visual interpretation' technique in favour of LULC mapping to achieve absolute accuracy in such a heterogeneous landscape, as it incorporates interpreter's knowledge. We appreciate the free availability of Landsat imageries having very good radiometry that has opened the doors for exercises with minimum cost. Located in one of the most fertile regions of India, the basin accommodates more than 400 million human population. This has led to expansion of agriculture and built-up land at the cost of forest and other land covers. Understanding landscape dynamics could help in designing an effective land-use policy for IGRB.Keywords

Traditional methods of association rule mining consider the appearance of an item in a transaction, whether or not it is purchased, as a binary variable. But, the quantity of an item purchased by the customers may be more than one, and the unit cost may not be the same for all items. A generalized form of the share mining model introduced to overcome this problem is utility mining. Developing an efficient algorithm is vital for utility mining because high utility itemsets cannot be identified by the pruning strategy. In this paper, we present two efficient approaches for utility pattern mining with the aid of FP-growth algorithm. The efficiency of utility pattern mining is achieved with two major concepts: 1) Incorporating the utility values after mining the frequent patterns (IUA-FP). Here, the patterns that are mined from the FP-growth algorithm are utilized to generate high utility patterns using internal and external utility. 2) Incorporating the utility values before mining the frequent patterns (IUB-FP). At this point, individual items that are less significant are taken out from the input database by considering their frequency along with their internal and external utility. Then, we apply the FP-growth algorithm in the transformed database to mine high utility patterns. Experimentation is carried out on these two concepts using synthetic dataset, T10I4D100K, attained from the IBM dataset generator and the performance study shows that the proposed two approaches are efficient in mining high utility patterns.

The task of classification is to assign a new object to a class from a given set of classes based on the attribute values of the object. The k-Nearest Neighbor (k-NN) is one of the simplest classification methods used in data mining and machine learning. Although k-NN can be applied broadly, it has few inherent problems, which is why researchers have proposed different extensions of the k-NN, or even ensemble formulations of k-NN classifiers. In our proposed CAk-NN (cluster and attribute weighted k-NN algorithm) algorithm, weight is assigned to each and every attribute of the training dataset so that the accurate distance matching can be possible. In addition to, clustering the training dataset reduces the execution time that is taken for classification and the resultant clusters are used to classify test instances. For this, we have proposed an attribute weighted k-means clustering algorithm that is used for partition the training dataset. After that, each centroid of the obtained cluster constitutes the sub-sample of input database, which is then used for classification. For testing case, distance measure based on attribute weight is calculated between a test instances with the mean of each cluster of training dataset. According to the computed distance measure, k-nearest neighbor cluster are identified and the class label is assigned if every cluster is from the same class. Otherwise, the relevant data records from the k-nearest cluster are retrieved and k-nearest neighbor data records are identified. Finally, the performance of the proposed CAk-NN algorithm is compared with the k-NN algorithm in terms of computation time and Classification accuracy using IRIS dataset.

The present work investigate on parametric study and optimization of process parameter in resistance spot weld efficiency of chromate micro-alloyed cold rolled mild steel sheets using L25 Taguchi design of experiments. The output responses are being studied as tensile shear strength of the weldment and nugget diameter which is affected by the input variables like weld current, electrode force and weld time. Both output responses were optimized to achieve effective values by using conventional Taguchi based Grey Relational Analysis and a Metaheuristics method as Genetic Algorithm. Here in present work two main goals specifically tensile shear strength and nugget diameter simultaneously optimized using multi-objective genetic algorithm. The analytical results were validated with experimental run so to analyze the efficiency of methods.Keywords

The aim of this study is to discover which kind of scaffolding can effectively promote learning. The past studies have shown mixed results in this regard. The process in which a domain expert gives and withdraws support in order to make a novice learner complete the task is known as scaffolding. A total of four distinct scaffold combinations and four groups were made. This experimental study was repeated twice to cross verify the outcomes using computer based learning environment (CBLE). The CBLE was designed with intelligent web program in PHP and jQuery to evaluate the solutions submitted by the learners instantly. The CBLE acted as an intelligent feedback system. In the first study, it was found that there was a significant effect of different scaffolding treatments on the learning outcomes, F (3,76) = 5.762, p=.001. The result analysis involves multiple comparisons based on Tukey HSD test and indicated that the mean score for the indirect support and adaptive fading (M=4.45, SD=1.191) was considerably different than the others. Likewise, second study also found that there was a significant effect of different scaffold treatments on the learning outcome, F (3,76) = 4.258, p=.008. The Tukey HSD test applied during the second study indicated that the mean score for the indirect support and adaptive fading (M=4.55, SD=1.19) was again significantly different than the others. The present study additionally measured the flow state of all the four groups using Kruskal-Wallis H test and found that indirect support and adaptive fading group was significantly different than direct support and adapting fading group as well as direct support and gradual fading group in both the studies.Keywords
