KNN Optimization for Multi-Dimensional Data

The K-Nearest Neighbors (KNN) algorithm is a simple but powerful technique used in the field of data analytics. It uses a distance metric to identify existing samples in a dataset which are similar to a new sample. The new sample can then be classified via a class majority voting of its most similar samples, i.e. nearest neighbors. The KNN algorithm can be applied in many fields, such as recommender systems where it can be used to group related products or predict user preferences. In most cases, the performance of the KNN algorithm tends to suffer as the size of the dataset increases because the number of comparisons performed increases exponentially. In this paper, we propose a KNN optimization algorithm which leverages vector space models to enhance the nearest neighbors search for a new sample. It accomplishes this enhancement by restricting the search area, and therefore reducing the number of comparisons necessary to find the nearest neighbors. The experimental results demonstrate significant performance improvements without degrading the algorithm’s accuracy. The applicability of this optimization algorithm is further explored in the field of Big Data by parallelizing the work using Apache Spark. The experimental results of the Spark implementation demonstrate that it outperforms the serial, or local, implementation of this optimization algorithm after the dataset size reaches a specific threshold. Thus, further improving the performance of this optimization algorithm in the field of Big Data, where large datasets are prevalent

SYSTEM AND METHOD FOR SECURE AUTHENTICATION BASED ON AN ATTRIBUTE VALUE

The present disclosure relates to a method and system for secure authentication of user devices based on an attribute value. The present disclosure suggests updating a new temporary attribute value when a user performs actions like locking, or shutting down a user device. Thereafter, an authenticated application or resource is accessed using the decrypted value, wherein the decrypted value is used to obtain the current HostName lock status value. If the current HostName lock status value is not the same as the predefined value in a decrypted string, access to the authenticated application resources is allowed, otherwise access is restricted. Once the user starts or restarts the device, temporary attribute lock is unlocked using a web portal or windows desktop program. Subsequently, the temporary attribute value is updated to a new attribute value

The Agathinai Components in Thirukkural

Based on the lives of the Sangam people, they created literature by distinguishing between love-genre literature and heroic-genre literature. The ambrosial Thirukkural, written by the world-famous Valluvar, is a universal holy verse and is a beacon to guide life and refresh literature that gives new meaning every time it is read. It is a book about life. Thirukkural is said to be suitable for all religions, all nations, and all times. In this book, Valluvar clearly explains the principles of the individual's life and how a mature man should be. Agam is a love feeling related to people's inner selves. Thinai is a discipline. So, love is an emotional discipline that can be called Agam. Kamathuppal (Love) is the third section of Thirukkural. This outlines the merits of the love-genre tradition. It has a literary flavour to it, and love reflects the lively character of chastity. It is Valluvar's 'Kamathuppal' that leads to the highest way of life, one-to-one. In this, the expression of love, commitment, and emotional values of the lovers are seen deliciously. Also, the characteristics, duties, and rights common to both sexes are explained. The agathinai components express love and pleasure. He has laid the foundation of love life in twenty-five chapters, divided into two parts: illicit courtship and chastity, which is the agam life. Ancient Tamils considered virtue as a way of life. If one lives a life of charity, one will get happiness. That pleasure is permanent. This article examines the agam components of domesticity as a virtue

Improvement of Microalga Biodiesel Production Capacity

This research is directed at developing renewable fuel sources, which are not only environmentally friendly, but also more importantly harvested faster and not competitive with agricultural land. For this reason, the potential oil-producing microalgae need to be explored, because it has fast growth and its cultivation development will not compete in land use with food agriculture. This study aims specifically to determine the types of microalgae producing biodiesel oil that can be isolated from the natural Wallacea in NTB waters, to determine light spectrum treatment and N elimination in microalgae culture which significantly increases the productivity and quality of the biodiesel it produces. Based on the distribution map of potential biofuel-producing microalgae types in NTB waters, samples will be collected from several NTB waters, then the target types of microalgae are isolated and cultured in two systems: a closed system (bioreactor) and an open system (raceway pool) with light spectrum variation treatment and elimination of N in microalgae culture nutrients to increase the productivity and quality of the biodiesel oil produced. Biomass was harvested every 48 hours from the bioreactor and every 4 weeks from the experimental pond. Microalgae biomass was extracted with hexane to produce primary oil. This primary oil usually still has a relatively high viscosity compared to petrodiesel, so it is then trans-esterified with methanol and an acid catalyst to increase the fire point and reduce its viscosity. Oil fractionation is also carried out to sort and determine the composition of saturated, mono-unsaturated and poly-unsaturated fatty acids which greatly determine the biodeasel quality of these microalgae. The biodiesel quality variables to be measured are density, viscosity, flash point, freezing point, solubility in water, vapor pressure, reactivity, physical appearance, odor and toxicity. The result showed that, in the community of marine microalgae from Lombok and Sumbawa Islands consist of 62 species of potential producing-oil microalgae were dominated by Bacteriastrum delicatulum, B. variance, Chaetoceros amini, C. affinis, C. liciniosum, C. lorenzianum, Gyrosigma sp., Nannochloropsis oculata, Nitzchia spp., Oscillatoria sp., Pseudonitzschia spp., and Thalassionema nitzschicoides. Types of oil-producing freshwater microalgae in Lombok Island consist of 19 species of potential producing-oil microalgae, identified with high abundance and dominance, covering Microcystis aeruginosa, M. incerta, Nostoc sp., and Pediastrum boryanum. The oil content of the three species of microalgae, namely Chaetoceros amini, Nannochloropsis oculata, and Nitzchia spp which had been cultured by trietmant were 34, 68, and 46% dry weight, respectively

Abstract : This study aims to explore the species richness of biodiesel-producing microalgae in the waters of West Nusa Tenggara to develop renewable energy source, environmentally friendly, and not compete in land use with the agricultural sector. Microalga  samples were collected from various waters in West Nusa Tenggara Province using the concentration method. Species determination   and data analysis of microalgae was carried out at the Biology Laboratory, University of Mataram to calculate the abundance of each species. The dominant species of biodiesel-producing microalgae were isolated and cultured by a closed culture system method. The oil content of the microalgae biomass produced was extracted by  a liquid-liquid extraction method using n-hexane as a solvent. The results show that of the 49 species of marine microalgae identified in the waters of West Nusa Tenggara, there are 12 species of microalgae which are biodiesel producers. Of the 30 freshwater microalga species, only 8 species of microalgae are producers of biodiesel. The microalgae community of marine waters of West Nusa Tenggara is dominated by Bacteriastrumdelicatulum, B. variance, Chaetocerosaffinis, C. liciniosum, C. lorenzianum, Gyrosigma sp., Oscillatoria sp., Pseudonitzschia spp., and Thalassionemanitzschicoides, while freshwater microalgae communities are dominated by Microcystis aeruginosa, M. incerta, Nostoc sp., Pediastrumboryanum, and Staurastumcristatum. The dominant types of biodiesel-producing microalgae isolated and cultured are Chaetocerosamini, Nannochloropsisoculata and Nitzschia spp. Each cell density of C. amini, N. oculata, and Nitzschiaspp in culture 7 days after isolation was 3,600,960,000,  4,375,360,000, and  3,368,640,000 cells / liter respectively  with oil content 34, 68, and 46%.
