CPI (Consumer price index) A consumer price index (CPI) measures changes in the price level of consumer goods and services purchased by households. The CPI is a statistical estimate constructed using the prices of a sample of representative items whose prices are collected periodically. GDP deflator In economics‚ the GDP deflator (implicit price deflator for GDP) is a measure of the level of prices of all new‚ domestically produced‚ final goods and services in an economy. GDP stands for gross

Objective The objective of this experiment is to understand reflection and refraction and how they vary with different matters. At the end of this experiment‚ you will be able to: Determine index of refraction of various solutions Recognize the passage of refracted beams though different medium Understand the concept of Snell’s Law Understand how the speed of electromagnetic waves in different matters are related Determine the critical angle for total internal reflection Materials 550

The refractive index Aim: The aim of this experiment is to find the refractive index of a glass prism. In this experiment‚ the independent variable is the angle of incidence‚ and the dependent variable is the angle of refraction. Theory: Snell’s law relates the angle of incidence and refraction to the ratio of the velocity of the wave in the different media. The formula for Snell’s law is the following: Sin isinr = v1v2 = n Where i is the angle of incidence‚ r is the angle of refraction

step index fiber It is an optical fiber which has a core of constant refractive index.there are two types of step index fibers:single mode si and multi mode si fiber single mode step index fiber has only one mode of EM propagation (HE11) an has a core diameter of about 8-12 Um. and multi mode si has many mode of propagation and has a core of diameter of about 50 Um which allow many no of modes through it. single mode step index has an adv of lower inter modal dispersion as there is only

Face-to-face vs. Electronic Communication We’re living in an age where e-mail‚ Facebook and digital connections are the rule‚ and face-to-face interactions start to become the exception. With the ability to exchange information via e-mail‚ chat and presentations over the web‚ face-to-face interactions with people seem to be unecessary. This is a harmful assumption that many people make. Without face-to-face communication intimacy is lost‚ there is greater misunderstanding‚ and people become

OVERVIEW INDEX NUMBERS compare figures which show changes in a given variable. The most common variables used in index numbers are price and quantity. By getting the difference of the index numbers‚ we are able to determine the relative or percent change in the price or quantity of a commodity between two periods of time or two localities. Among the more commonly used index numbers are the consumer price index‚ retail price index‚ wholesale price index‚ and the cost-of-living index. DEFINITION

INDEX NUMBER Introduction Sebuah index menunjukkan perubahan relatif yang terjadi pada sebuah nilai dari satu periode ke periode yang lain. Kegunaan index‚ misalnya pada Consumer Price Index‚ adalah mengukur perubahan harga pada suatu kelompok besar dari barang-barang yang dibeli konsumen. Simple Index Numbers Angka index adalah suatu angka yang menunjukkan perubahan relatif pada harga‚ jumlah‚ atau nilai dibandingkan dengan suatu base period. Jika angka index yang digunakan untuk mengukur

FDI: is a direct investment into production or business in a country by an individual or company of another country‚ either by buying a company in the target country or by expanding operations of an existing business in that country. Horizontal FDI: Processes conducted at home country are replicated directly in the host country. Vertical FDI: performs value-adding activities either upstream or downstream on the processes in host country. MNE: A company with operations in multiple locations across

The index of dissimilarity The index of dissimilarity measures the evenness of two racial groups distributed across an area in relation to a larger area. The scale ranges from zero‚ complete integration‚ to one‚ complete segregation. The index can be used with the analysis of racial segregation in trends dealing with socioeconomic class‚ immigration‚ nativity‚ and residence. Generally‚ without immigration‚ the dissimilarity index between two races decreases as time goes on. This trend is most noticeable
