Embedded Web Server based Interactive data acquisition and Control SystemIOSR Journals
This document summarizes an embedded web server based interactive data acquisition and control system. The system uses an ARM9 processor running RTLinux to both acquire data from sensors and control industrial devices. It allows remote monitoring and control via a web browser. The ARM9 handles data acquisition, control functions, and an embedded web server simultaneously. Analog sensor signals are converted to digital with an ADC and stored in external memory. The web server portion allows clients to access the stored data and send control instructions via HTML pages to the ARM9 over Ethernet. This embedded single-board solution provides real-time data acquisition and control with remote access capabilities.
Investigation and Analysis of SNR Estimation in OFDM systemIOSR Journals
Estimation of signal to noise ratio (SNR) of received signal and to transmit the signal effectively for
the modern communication system. The performance of existing non-data-aided (NDA) SNR estimation methods
are substantially degraded for high level modulation scheme such as M-ary amplitude and phase shift keying
(APSK) or quadrature amplitude modulation (QAM).In this paper SNR estimation proposed method which uses
zero point auto-correlation of received signal per block and auto/cross- correlation of decision feedback signal
in orthogonal frequency division multiplexing (OFDM) system. Proposed method can be studied into two types;
Type 1 can estimate SNR by zero point auto-correlation of decision feedback signal based on the second
moment property. Type 2 uses both zero point auto-correlation and cross-correlation based on the fourth
moment property. In block-by-block reception of OFDM system, these two SNR estimation methods can be
possible for the practical implementation due to correlation based the estimation method and they show more
stable estimation performance than the earlier SNR estimation methods.
Dynamics of Twointeracting Electronsinthree-Dimensional LatticeIOSR Journals
The physical property of strongly correlated electrons on a three-dimensional (3D) 3 x 3 x 3 cluster of the simple cubic lattice is here presented.In the work we developed the unit step Hamiltonian as a solution to the single band Hubbard Hamiltonian for the case of two electrons interaction in a finite three dimensional lattice. The approximation to the Hubbard Hamiltonian study is actually necessary because of the strong limitation and difficulty pose by the Hubbard Hamiltonian as we move away from finite - size lattices to larger N - dimensional lattices. Thus this work has provided a means of overcoming the finite - size lattice defects as we pass on to a higher dimension. We have shown in this study, that the repulsive Coulomb interaction which in part leads to the strong electronic correlations, would indicate that the two electron system prefer not to condense into s-wave superconducting singlet state (s = 0), at high positive values of the interaction strength. This study reveals that when the Coulomb interaction is zero, that is, for free electron system (non-interacting), thevariational parameters which describe the probability distribution of lattice electron system is the same. The spectra intensity for on-site electrons is zero for all values of the interaction strength

El documento describe la importancia del agua y los diferentes estados en que puede encontrarse. Explica que el agua es esencial para la vida y compone la mayor parte de los seres vivos. Además, enumera consejos para cuidar el agua como cerrar llaves mientras no se usen, usar regadera en lugar de bañera, reparar tuberías que gotean y usar cubetas para lavar en vez de manguera.
Este documento trata sobre la drogadicción. Explica que la drogadicción es una enfermedad causada por la dependencia a sustancias que afectan el sistema nervioso central. Detalla los diversos efectos que pueden tener las drogas dependiendo del tipo y cantidad consumida, como alucinaciones o la muerte. Además, describe los dos tipos de dependencia que produce: física y psíquica. Finalmente, ofrece algunas señales para identificar a un drogadicto y resalta la necesidad de construir una sociedad con valores espirituales

The patent document describes an electric distribution system with enhanced protection capabilities. It includes at least one feeder with segments having protective devices and electric current measuring devices at each end. A processor determines the difference between synchronized current measurements at the ends and uses this to determine switching conditions of the protective devices, allowing for improved coordination of protection even with distributed generation sources on the system. The system aims to address issues that traditional protection schemes have in the presence of bidirectional fault currents from distributed generation.
The document discusses Hive, a data warehouse infrastructure built on Hadoop. It provides an overview of Hive architecture and components. Key concepts discussed include Hive query language (HQL), creating and managing databases and tables in Hive, loading and querying data, partitioning tables for performance, and bucketing data for distributed processing. The document appears to be from a presentation or lecture on Hive and big data technologies.
This document contains a quiz with questions about computer awareness and concepts. It includes 55 multiple choice questions covering topics like computer hardware, operating systems, software, networking, internet, security and more.

While man-made creations may struggle to match nature's beauty, music is one thing that can come close by capturing the essence of nature through sound. Music has an ability to reflect qualities found in nature like emotion, movement, and life through its melodies and harmonies.
