 | Paper TitleTRANSACTION DATABASE AND SUPPORT FOR ITEM SETS IN PARALLEL MININGAbstractMining 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.

| Paper TitleANALYSING DIFFERENT NANO FILLER WITH POLYMER NANO COMPOSITESAbstractThe 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
| Paper TitleENVIRONMENTAL CHANGES: CAUSES AND EFFECTS ON THE BIOSPHEREAbstractIn 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.

| Paper TitleSTUDY OF PROPOSING A FRAMEWORK FOR AUTOMATIC MANAGEMENTAbstractTo inspect the performance of our proposed approach for a BoT application, real responsibility follows accessible from Parallel Workload Archive are utilized. The general purpose of this project is to build and develop models and algorithms for energy efficient resource allocation while taking into account a variety of factors. The importance of the two levels, as well as their respective functions, is discussed. To map the tasks of a BoT application to VM instances, a new scheduling mechanism dubbed DBOGA has been presented. The VM instances are assigned to hosts at the data centre level. It is modeled after the bin-packing problem, and a new crossover operator is proposed to improve the grouping genetic algorithm. The encouraging results suggest that the proposed system may reduce cost and energy consumption while also maximising resource utilization within the application deadline restrictions.

Page 29-32
| Paper TitleCR-DOPED PBS THIN FILMS GROWN BY CHEMICAL BATH DEPOSITION IN DEVELOPING HD- D DOPED CHARACTERISTICSAbstractChemical bath deposition will used to create nanocrystalline undoped and Cr-doped PbS thin films on glass substrates, respectively. Polycrystalline films with cubic structure were found by X-ray diffraction to grow preferentially in the (111) direction. PbS crystallite size decreased from 59.97 nm to 37.59 nm with Cr inclusion, whereas strain and dislocation density increased. There are three different doping levels for Cr based on the EDX spectrum, with a ratio of 0.63, 1.75, and 4.70 percent. The average size of nanoclusters reduced from 73 nm to 41 nm as the Cr content rose, according to morphological examination. As the amount of Cr doped is raised, so are the optical band gap values. Photoelectrochemical (PEC) reactions and the photoelectrodes\' stability were examined in 0.3 M Na2SO3 electrolyte solution. In addition, the incident and applied bias photon-to-current efficiencies were computed and exhibited optimum values of 13.5 percent and 1.44 percent at 0.68 V and 390 nm, respectively. Besides that, the improved electrode has a long life span and a high chemical stability. Finally, the effect of temperature on PEC behaviour is investigated and thermodynamic parameters are derived.

SIGNAL DISTORTION AND NOISE REDUCTION TECHNIQUES IN ANALOG SYSTEMS
| Paper TitleSIGNAL DISTORTION AND NOISE REDUCTION TECHNIQUES IN ANALOG SYSTEMSAbstractSpeech is a signal produced by humans to interact and communicate. Different information is gained from speech signals, such as the language being spoken, emotion, gender, speaker identification, and other information. Speech signals are exposed to different noises, which can be generated at the beginning of the speech or during the transmission. Due to this problem, noise reduction processes are an interesting field in different communication application systems that cultivate the intelligibility and quality of speech signals. It refers to removing or reducing the background noise in order to obtain an improved quality of the original speech signal without distorting the original signal. This paper reviews the state-of-the-art research, reviewing different speech enhancement filters and algorithms and comparing their performance to reach a conclusion about which is the best filter or the most effective one based on the kind of noise that was used and the most difficult noise to remove from the signal. Signal integrity and noise reduction remain central challenges in both analog and digital signal processing. The preservation of signal fidelity during acquisition, transmission, and transformation is vital for high-performance systems in domains such as telecommunications, biomedical instrumentation, and radar systems. This paper presents a comprehensive review and application of advanced techniques that enhance signal integrity and mitigate noise in both the time and frequency domains. Emphasis is placed on adaptive filtering, wavelet-based denoising, spectral shaping, and hybrid approaches that combine deterministic and statistical models.
