TRANSACTION DATABASE AND SUPPORT FOR ITEM SETS IN PARALLEL MINING

Abstract

Mining frequent itemsets in large databases is a widely used technique in Data Mining. Several sequential and parallel algorithms have been developed, although, when dealing with high data volumes, the execution of those algorithms takes more time and resources than expected. Frequent itemset mining is the essential step of data mining process. Further frequent itemset is a primary data obligatory for association rule mining. The Apriori and FP tree are conventional algorithms for mining frequent itemset and envisaging association rules based on it for know ledge discovery. The process of updating database continuously is known as incremental data mining. In real life, database updates recurrently where exactly conventional algorithms perform incompetently. If we could use the previous analysis is to incrementally mine the frequent itemset from the updated database, the mining process would become more efficient and cost of mining process would be minimized. In this research, we propose a novel incremental mining scheme with a parallel approach for discovering frequent itemset. It uses a data structure called IMBT. It is a Incremental Mining Binary Tree w hic h is used to record the itemset in an efficient way. Furthermore, our approach needs not to predetermine the minimum support threshold and scans the database only once.

ANALYSING DIFFERENT NANO FILLER WITH POLYMER NANO COMPOSITES

Abstract

The development of polymer nanocomposites has been an area of high scientific and industrial interest in the recent years, due to several improvements achieved in these materials, as a result of the combination of a polymeric matrix and, usually, an inorganic nanomaterial. The improved performance of those materials can include mechanical strength, toughness and stiffness, electrical and thermal conductivity, superior flame retardancy and higher barrier to moisture and gases. Nanocomposites can also show unique design possibilities, which offer excellent advantages in creating functional materials with desired properties for specific applications. The possibility of using natural resources and the fact of being environmentally friendly have also offered new opportunities for applications. This chapter aims to review the main topics and recent progresses related to polymer nanocomposites, such as techniques of characterization, methods of production, structures, compatibilization and applications. First, the most important concepts about nanocomposites will be presented. Additionally, an approach on the different types of filler that can be used as reinforcement in polymeric matrices will be made. After that, sections about methods of production and structures of nanocomposites will be detailed. Finally, some properties and potential applications that have been achieved in polymer nanocomposites will be highlighted.

ENVIRONMENTAL CHANGES: CAUSES AND EFFECTS ON THE BIOSPHERE

Abstract

In today’s world degradation of the environment is one of the most serious challenges before mankind. The planet without a human population has been also suffering from these problems with the areas under human inhabitation. Environmental degradation is a wide-reaching problem and it influences the health of the human population greatly. The environment is deteriorating as resources such as air, water, and soil are depleted. The recent activities in the field of socio-economics, institute, and technology play a major role in degrading our environment. The interactions between human beings and the environment have often been viewed mechanistically. The degradation and depletion of natural resources and climate change pressure on green areas have become major concerns for human life. In response to these problems, an extremely important function of the ecosystem is to provide healthy and sustainable environments for both natural systems and communities. Therefore, ecological planning is a functional requirement for the establishment of sustainable development of the environment. With ecological planning, human needs are supplied while natural resources are used in the most effective and sustainable manner and the maintenance of ecological balance is sustained. The present article recommends the various steps which should be taken for reducing environmental degradation. It is necessary that governments, international organizations, and communities should and must work together at all levels to combat the health risks to humankind associated with environmental degradation and its contributing factors, such as climate change.
