The differential wave equation can be used to describe electromagnetic waves in a vacuum. In the one dimensional case, this takes the form $\frac{\partial^2\phi}{\partial x^2}-\frac{1}{c^2}\frac{\partial^2\phi}{\partial t^2} = 0$. A general function $f(x,t) = x \pm ct$ will propagate with speed c. To represent the properties of electromagnetic waves, however, the function $\phi(x,t) = \phi _0 sin(kx-\omega t)$ must be used. This gives the Electric and Magnetic field equations to be $E (z,t) = \hat{x} E _0 sin(kz-\omega t)$ and $B (z,t) = \hat{y} B _0 sin(kz-\omega t)$. Using this solution as well as Maxwell's equations the relation $\frac{E_0}{B_0} = c$ can be derived. In addition, the average rate of energy transfer can be found to be $\bar{S} = \frac{E_0 ^2}{2 c \mu _0} \hat{z}$ using the poynting vector of the fields.

En el siguiente ensayo, usted podrá encontrar encuestas que le brindaran información disponible en la pagina web del DANE, que le mostraran los diferentes estratos socioeconómicos en la ciudad de Medellín. El propósito de este ensayo es mostrar una relación entre los ingresos de los individuos y su felicidad. Dado a que la mayoría de la población de Medellín consta con bajos recursos y sufren necesidades por la falta de ciertas modalidades indispensables para sobrevivir, ellos son felices y están plenos con su estilo de vida.

This article is about the growth of Wikipedia and it's dynamics. This article basically speaks about the prediction of extent of world's knowledge accumulated in Wikipedia and the way in which edit wars help the accumulation of knowledge to develop a quality wikipedia article.

Biopsihosocialni model zdravja in bolezni, ki ga je leta 1977 teoretiziral George L. Engel predstavlja primarno paradigmo zahodne psihiatrije ter meni, da na nastanek, izbruh ter potek bolezni sovplivajo biološki, psihološki in socialni dejavniki; zdravje torej najbolje razlagamo kot produkt treh komponent. V nasprotju z biomedicinskim modelom človeka določa celostno (ne pojmuje ga kot stroj), raspravlja o determinantah zdravja (katerikoli kombinaciji dejavnikov, ki neposredno ali posredno povzroči spremembo v zdravstvenem stanju), in na slednje se tudi osredotoča (ne pa na bolezen) . Pomembno je poudariti, da obravnavani model ne ponuja enostavne, prilagodljive šablone za pojasnjevanje interakcij ali naključnih vpljivov posamezne komponente , a kvečjemu splošen okvir za usmerjanje teoretičnega in empiričnega raziskovanja.

Description of results of fieldwork at Pocono Environmental Education Center with students from Malcolm X Shabazz High School, May 2005.

Using WebRTC we are trying to develop a prod- uct called 'Ping' used for audio, mult-video, file and screen sharing. Ping uses WebRTC for the source of data exchange and XMPP Server for signalling and transporting. Ping works on Browser to Browser connections instead of naive client server approach. Ping guarentees high scalability and upto 60% more efficiency than existin
