Sound to elelectricity
Sound or popularly known to us as noise is one of the widely available energy sources which have its range extending al-most to infinity. The noise is considered to be a great contribu-tor in the increasing pollution which is studied under the cat-egory of noise pollution.
Let us first understand the basic definition of sound. Sound basically is mechanical wave that is an oscillation of pressure transmitted through some medium (like air or water), com-posed of frequencies which are within the range of hearing. Thus, considering sound as the wave we can imagine it as the flow of energy from one point to another with the help of a medium as air. The sound waves can be longitudinal as well as transverse as per direction of vibration of the sound parti-cles called phonons.
Sound that is perceptible by humans has frequencies from about 20 Hz to 20,000 Hz. In air at standard temperature and pressure, the corresponding wavelengths of sound waves range from 17 m to 17 mm.
How sound is converted to energy
This document provides an overview of converting sound energy to electricity. It discusses piezoelectric crystals and Sonea devices that can directly convert sound into electricity. Acoustic sound harvesting is described as the process of capturing sound energy, storing it, and controlling it for small devices. An experiment conducted in London successfully harvested the power of footfall and generated electricity. Potential applications of this conversion technique include powering small devices and sensors. While it can utilize wasted sound energy, limitations include low power densities of sound waves.
Wireless electricity trensfer
This document summarizes wireless electricity transmission. It discusses that wireless electricity involves transferring electricity without a physical connection between the input and load using magnetic rays. It works on the principle of mutual induction between two coils, with one coil connected to a power source generating an oscillating magnetic field, and a second coil converting this back into electricity to power a light bulb. Wireless transmission could be useful for powering devices like phones and laptops without needing to recharge batteries. While it provides advantages like delivering power anywhere without wires, there are also challenges like power loss if metal objects interfere with magnetic fields and need for standardization to prevent overheating from different voltages.

Операционная сторона интернет-магазина: как не терять клиентов
Презентация Панарина Виталия с крупнейшей российской интернет-конференции РИФ+КИБ 2013 (www.rif.ru).
В докладе рассматриваются вопросы увеличения операционной конверсии интернет-магазина.
Конверсией считается отношение заказов, совершенных в интернет-магазине по отношению к его посещаемости. То, что происходит дальше, как правило не так подробно обсуждается. Но потери, конечно, возникают и на последующих этапах взаимодействия с покупателем. При этом причины могут быть различными: от скорости обратного звонка из колл центра, до внешнего вида и вежливости курьеров. На некоторые из этих факторов есть возможность влиять напрямую, на некоторые нет. Но упускать их из вида не стоит. О том, за чем стоит следить и идет речь в докладе.

Ch 19 using electricity 2-e
This chapter discusses electrical safety and hazards. It explains that electrocution, burns, fires and explosions are dangers of improper electricity use. Damaged insulation, overloading, overheating, damp conditions and poor connections can cause hazards. The chapter also describes safe electricity use at home, including proper three-pin plug wiring, using fuses of the correct rating, and ensuring appliances are earthed or have double insulation.

witricity
Witricity is the transmission of electricity without wires over mid-range distances using magnetic induction. It was first conceptualized in the early 1900s but was rediscovered in 2007 by MIT researchers who were able to illuminate a lightbulb wirelessly. Witricity works by using an oscillating magnetic field from a power source coil to induce an electric current in a receiving coil within a few meters. While it provides the benefits of untethered power for devices, witricity's efficiency decreases with distance and it is limited to transmitting power over mid-range distances of up to a few meters. Potential applications include wirelessly charging consumer electronics, electric vehicles, and industrial and medical devices.

Electric current
This document discusses electric currents, which are flows of electric charge that are typically carried by electrons in a conductor. The standard unit for measuring current is the ampere, defined as one coulomb of charge passing per second. Currents can be measured using an ammeter and induce magnetic fields that are important for technologies like motors and generators. Conductors readily allow electric currents due to movable electrons, while insulators have internal charges that do not flow freely, making them poor conductors of current.

Halloween safety-1
Halloween is celebrated on October 31st. Children dress up in costumes and go trick-or-treating by knocking on doors and saying "trick or treat" to receive candy. Safety tips include walking with an adult, not eating candy until checked by parents for safety, carrying a flashlight, and wearing clear costumes without weapons or anything that could cause tripping. Popular Halloween activities include trick-or-treating, bobbing for apples at parties, and adults wearing costumes to work or company parties.
Halloween
Halloween originated 2000 years ago among Celtic pagans in Ireland, England, and France. They celebrated Samhain on October 31st, when spirits of the dead were believed to return to Earth. People wore costumes to avoid recognition by ghosts. As Christianity spread, the holiday was changed to All Saints' Day on November 1st. Trick-or-treating began as poor people begging for soul cakes in return for prayers. Irish immigrants brought Halloween traditions to America in the 1800s, carving pumpkins instead of turnips and celebrating with costumes and candy.
Middle ages
The document summarizes the history of the Iberian Peninsula from the fall of the Western Roman Empire in 476 CE to the end of the Reconquista in 1492 CE.
