Effective index formula
WebSep 27, 2013 · In this paper, a number of polymeric waveguide structures have been analyzed by using two distinct techniques which are: effective index method (EIM) and numerical simulation based on finite difference method (FDM). The main aim of this investigation is the calculation of effective indexes (EI) of the following structures: rib, …

WebThe refractive index determines how much the path of light is bent, or refracted, when entering a material.This is described by Snell's law of refraction, n 1 sin θ 1 = n 2 sin θ 2, where θ 1 and θ 2 are the angle of incidence and angle of refraction, respectively, of a ray crossing the interface between two media with refractive indices n 1 and n 2.The … WebREER = CERn x CERn x CERn x 100. Here, CER represents the country’s exchange rate. The Step-by-step calculation process is as follows. The exchange rate average is calculated after designating the weightage of each rate. For example, if a currency has a 40% weightage, the exponential power of the exchange rate is raised to 0.40.
WebTherapeutic index (TI) measurement of drug safety. refers to the relationship between toxic and therapeutic dosing. TI = TD50/ED50. therapeutic index of a drug is the ratio of the dose that produces toxicity to the dose that produces a clinically desired or effective response. TD50 = the dose of drug that causes a toxic response in 50% of the ... WebThe odds ratio formula is as follows: Odds Ratio = (a*d)/ (b*c). Standardized Mean Difference: Cohen’s D is the most common method. It measures the standardized mean difference. It is computed as follows: Effect Size = (μ1-μ2)/σ. Correlation Coefficient: The correlation coefficient.
WebHousing Affordability Index (Composite) - Measures the degree to which a typical family can afford the monthly mortgage payments on a typical home. Formula: (MEDINC/QINC)*100. Key: IR = Interest Rate. MEDPRICE = Median price of existing single-family home sale. PMT = Monthly payment. MEDINC = Median Family Income. MINC = … WebMar 23, 2016 · Days Sales Outstanding (DSO) is a useful formula to measure the average age of accounts receivable. As a management tool, it can be used to track and improve collections as well as motivate employee performance. DSO = ( Accounts Receivable / Total Credit Sales) * 365. DSO is not a measurement of effectiveness, rather efficiency.
