Analysis of industrial flame characteristics and constancy study using image ...BIBHUTI BHUSAN SAMANTARAY
The study of characterizing and featuring different kinds of flames has become more important than ever in order to increase combustion efficiency and decrease particulate emissions, especially since the study of industrial flames requires more attention. In the present work, different kinds of combustion flames have been characterized by means of digital image processing (DIP) in a 500 kW PF pilot swirl burner. A natural gas flame and a set of pulverized fuel flames of coal and biomass have been comparatively analyzed under co-firing conditions. Through DIP, statistical and spectral features of the flame have been extracted and graphically represented as two-dimensional distributions covering the root flame area. Their study and comparison leads to different conclusions about the flame behavior and the effect of co-firing coal and biomass in pulverized fuel flames. Higher oscillation levels in co-firing flames versus coal flames and variations in radiation regimen were noticed when different biomasses are blended with coal and brought under attention.
CHARACTERIZATION AND EMISSION ANALYSIS OF PREMIXED AND PREHEATED POROUS RADIA...BIBHUTI BHUSAN SAMANTARAY
This document summarizes an experimental study on the characterization and emission analysis of premixed and preheated porous radiant burners during LPG combustion. Experiments were conducted on 13 different burners made of brass and cast iron with varying geometric parameters like diameter, thickness, pore size, number of pores, and pore distribution. The maximum thermal efficiency obtained was 64.59% for a cast iron burner with the largest diameter and pore distribution. Material, pore geometry, and firing rate significantly affected thermal efficiency and emissions. Burner material, precise pore design, and optimal firing rate are important to improve efficiency while meeting emission standards.

The document presents two solutions for secure internet banking authentication - one based on short-time passwords using hardware security modules, and the other based on certificate-based authentication using smart cards. It discusses current authentication threats like offline credential stealing and online channel breaking attacks. Both proposed solutions offer strong security against these common attacks, with the certificate-based solution being highly attractive for the future due to changing legislation and the spread of electronic IDs.
El documento habla sobre el plagio, definiéndolo como la utilización de material ajeno sin reconocer su fuente. Explica que para evitar el plagio se debe citar y reconocer debidamente las fuentes de información, ya sea entre comillas para citas textuales o reconociendo el autor en paréntesis. También advierte sobre las consecuencias de ser descubierto cometiendo plagio y recomienda apostar por el conocimiento en lugar de la mediocridad.

Los estándares nacionales proporcionan criterios claros y públicos para establecer niveles básicos de calidad educativa para todos los niños en Colombia. La estructura de los estándares se utiliza para planificar lecciones siguiendo el enfoque PPP (presentación, práctica, producción), en donde los estudiantes se dividen en grupos para diseñar una mini lección de 20 minutos siguiendo los pasos propuestos.
El documento es un certificado de estudios del Liceo Nacional Antonia Santos que acredita que Lina Maria Naranjo Piza y Maria Fernanda Quintero Paez completaron sus estudios allí. Doris Pinto firmó el certificado como la rectora del liceo.
This document lists various products related to refineries, power plants, and oil and gas facilities including switchgears, piping, instruments, equipment, automation systems, lighting, cables, and more. It also provides a website for PSN Energy Systems which deals in substation products and products for power plants and the oil and gas industries.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
The document describes the configuration details of a scheduler that runs jobs to export social media data from various sources to a universal profile database. It outlines the deployment environment, database connections, configurable jobs, and MySQL tables used to track scheduled jobs and export status. The system job checks for new jobs every 20 minutes and exports occur based on cron expressions for profiles, conversations, followers/followings. Failure details are captured in MongoDB collections.
A empresa de tecnologia anunciou um novo smartphone com câmera aprimorada, maior tela e bateria de longa duração. O dispositivo também possui processador mais rápido e armazenamento expansível. O novo modelo será lançado em outubro por um preço inicial de US$799.
The applicant is applying to serve on the management committee for the Reliability and Maintainability Symposium (RAMS). The application requests basic contact information as well as the applicant's education background, work experience, published papers, and confirmation that their employer approves and will financially support their participation on the committee if selected.
O documento lista nomes de atrizes populares e anuncia um novo filme chamado "A ARTE DE ENGANAR AS MULHERES", sugerindo que mulheres geralmente se interessam por homens com dinheiro, poder e bens materiais ao invés de homens em si.

Este documento apresenta as regras e procedimentos para o curso "Educação Inclusiva: Avanços e Desafios" oferecido pela Diretoria de Ensino da Região de Suzano. O curso terá duração total de 35 horas entre aulas presenciais e a distância e abordará temas como educação especial, ERER e gênero. O documento detalha o público-alvo, pré-inscrição, cronograma, avaliação, certificação e responsabilidades dos cursistas.
This presentation explores the strengths and weaknesses of ordinary least squares and propensity score matching. Matching alone cannot solve endogeneity problems faced by OLS. The presentation shows how PSM and OLS can be combined to yield less-biased estimators than either method alone.
The document discusses methods for determining sample sizes in reliability testing. It covers two main approaches: the estimation approach which aims to control the confidence interval width, and the risk control approach which aims to control type I and type II errors. Examples are provided to demonstrate how to use each approach to determine the needed sample size given parameters like required reliability, confidence level, allowable failures. Both parametric and non-parametric methods are introduced for different test scenarios. Software tools can help calculate the sample sizes required to meet the test objectives.
