Labelled Classifier with Weighted Drift Trigger Model using Machine Learning for Streaming Data Analysis

The term “data-drift” refers to a difference between the data used to test and validate a model and the data used to deploy it in production. It is possible for data to drift for a variety of reasons. The track of time is an important consideration. Data mining procedures such as classification, clustering, and data stream mining are critical to information extraction and knowledge discovery because of the possibility for significant data type and dimensionality changes over time. The amount of research on mining and analyzing real-time streaming data has risen dramatically in the recent decade. As the name suggests, it’s a stream of data that originates from a number of sources. Analyzing information assets has taken on increased significance in the quest for real-time analytics fulfilment. Traditional mining methods are no longer effective since data is acting in a different way. Aside from storage and temporal constraints, data streams provide additional challenges because just a single pass of the data is required. The dynamic nature of data streams makes it difficult to run any mining method, such as classification, clustering, or indexing, in a single iteration of data. This research identifies concept drift in streaming data classification. For data classification techniques, a Labelled Classifier with Weighted Drift Trigger Model (LCWDTM) is proposed that provides categorization and the capacity to tackle concept drift difficulties. The proposed classifier efficiency is contrasted with the existing classifiers and the results represent that the proposed model in data drift detection is accurate and efficient

Abstract The design of Tri-Band, 1X8 Linear Antenna Array that operates in three bands 5.4GHz, 6.2GHz, 9.2GHz with the perspective that the antenna array has multiple resonating frequencies and is able to modify its radiation pattern as well, using Micro-strip Patch Antenna elements in combination with PIN Diodes and beam can be steered in each iteration by controlling the supply of PIN Diodes

Casting alloys: the saga of their existence and the recipe of their blend

Though a variety of metals and combinations have been in use since decades in the field of dentistry, there are only a few which have sustained the challenges of evolving material science. The history of these alloys, their constituent metals and properties impart the rationale of their use both in the past and advancing future perspectives. Also bearing the environmental hazards in laboratory and clinical environments, safe levels of exposure to these alloys and aspects of selecting the best option among the different alternatives is important

Dokur Village at a Glance

Dokur village, located in Mahbubnagar district of Andhra Pradesh was chosen for Village-Level Studies (VLS) initiated in 1975 by the Economics Program of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Hyderabad. The present Mahbubnagar district is also known as Palamooru, located in the Telangana Region of Andhra Pradesh. Dokur village (16° 36’ N and 78° 50’ E) is situated in Devarkadra mandal in Mahbubnagar District (16° 73’ N and 77° 98’ E). Dokur’s original name was “Dakur” derived from the Indo-Persian Urdu word “daku,” meaning “gang of armed dacoits”. It is believed that dacoits used to take shelter in Dakur due to its thick vegetation. Eventually, the name Dakur became corrupted to Dokur. Dokur is about 130 km from Hyderabad. To reach Dokur from Hyderabad, one needs to travel to Mahbubnagar district headquarters and then to Deverkadra mandal on the surfaced Hyderabad- Raichur road, and then travel a further distance of seven kilometers south on a metal road. Autorickshaws and Road Transport Corporation buses are the main means of transportation from Devarkadra to Dokur

High-quality variational wave functions for small 4He clusters

We report a variational calculation of ground state energies and radii for 4He_N droplets (3 \leq N \leq 40), using the atom-atom interaction HFD-B(HE). The trial wave function has a simple structure, combining two- and three-body correlation functions coming from a translationally invariant configuration-interaction description, and Jastrow-type short-range correlations. The calculated ground state energies differ by around 2% from the diffusion Monte Carlo results.Comment: 5 pages, 1 ps figure, REVTeX, submitted to Phys. Rev.

Seaweed resources off Tamil Nadu coast: Kattapadu- Tiruchendure

The southern coast of Tamil Nadu from Mandapam to Kanyakumari supports luxuriant growth of economically important seaweeds and the total standing crop was estimated at 22,000 tonnes (wet). All the seaweed based industries in India mostly depend on the raw material available from this area. The seaweeds exploited from this region, particularly the agarophytes Gelidiella acerosa and Gracilaria edulis are insuiBcient to meet the raw material requirement of the industrie

Performance of a Low Heat Rejection Diesel Engine With Air Gap Insulated Piston

Introduction The second law requirement of Thermodynamics necessitates the inevitable heat loss to the coolant to realise work output. Any saving in this part of the energy distribution would either increase the energy lost through exhaust gases or increase the power output. Considerable efforts are under way to reduce heat loss to the coolant by various researchers. However, the results are a little confusing as to whether the insulation would improve or deteriorate thermal efficiency. The two approaches that are being pursued to decrease heat rejection are (1) ceramic coating and (2) air gap insulation. Both these methods are still having problems. Ceramic coatings are found to be peeling off over a period of operation. There are serious problems of leakage of gases in the case of air gap insulation. A two zone combustion model was used by A study of the existing literature on LHR engines thus reveal

Distribution of marine algae and seagrass off Valinokkam-Kilakkarai, Tamil Nadu coast

The deep water area between Valinokkam and Kilakkarai in Tamil Nady coast covering an area of 200 sq.km. was surveyed for the distribution of marine algae and seagrasses during January 1989. Totally 33 species of marine algae were recorded of which 8 species belonged to Chlorophyta, 8 to Phaeophyta and 17 to Rhodophyta. Only one species of seagrass Halophila ovalis occurred in the whole area surveyed. The vertical distribution of seaweeds and their abundance were investigated. Hydrological data collected from the area surveyed are presented

Interfacial Tension of the Lipid Membrane Formed from Phosphatidylcholine–Decanoic Acid and Phosphatidylcholine–Decylamine Systems

Interfacial tension has been determined for phosphatidylcholine (PC)–decanoic acid (DA) and PC–decylamine (DE) membranes. PC (lecithin), DA and DE were used in the experiments; the interfacial tension values of the pure components are 1.62 × 10−3, −2.38 × 10−2 and −3.88 × 10−2 N/m (hypothetical values for DA and DE), respectively. The 1:1 complexes were formed during formation of PC–DA and PC–DE membranes. The following parameters describing the complexes were determined: the surface concentrations of the lipid membranes formed from these complexes, \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A_{3}^{ - 1}$$\end{document}; the interfacial tensions of such membranes, γ3; and the stability constants of these complexes, K
