Frequency-resolved optical gating (FROG) is a general method for measuring the spectral phase of ultrashort laser pulses, which range from subfemtosecond to about a nanosecond in length. Invented in 1991 by Rick Trebino and Daniel J. Kane, FROG was the first technique to solve this problem, which is difficult because, ordinarily, to measure an ...
Double-blind frequency-resolved optical gating (double-blind FROG) is a method for simultaneously measuring two unknown ultrashort laser pulses. Well established ultrafast measurement techniques such as frequency-resolved optical gating and its simplified version GRENOUILLE can only measure one unknown ultrashort laser pulse at a time.
Marketing mix modeling (MMM) is an analytical approach that uses historic information to quantify impact of marketing activities on sales. Example information that can be used are syndicated point-of-sale data (aggregated collection of product retail sales activity across a chosen set of parameters, like category of product or geographic market) and companies’ internal data.
RFM-I – Recency, Frequency, Monetary Value – Interactions is a version of RFM framework modified to account for recency and frequency of marketing interactions with the client (e.g. to control for possible deterring effects of very frequent advertising engagements).
It is believed that there is an optimal way of allocating budgets for the different elements within the promotional mix to achieve best marketing results, and the challenge for marketers is to find the right mix of them. Activities identified as elements of the promotional mix vary, but typically include the following:
Marketing mix is the most important part of marketing strategy, which is "the framework to manage marketing and incorporate it within a business context [6] ". Marketing strategy: how a business achieves its marketing objectives. The initial step to achieve a marketing strategy is to identify the market target and build up a business plan. [6]
The frequency axis has units of FFT "bins" when the window of length N is applied to data and a transform of length N is computed. For instance, the value at frequency 1 / 2 "bin" is the response that would be measured in bins k and k + 1 to a sinusoidal signal at frequency k + 1 / 2 . It is relative to the maximum possible ...
SBU's in the matrix can be represented as a circle; the radius exhibits the size of the market, the SBU's holdings in the market are equated through a pie chart within the circle and an arrow outside the circle shows the standing of the SBU expected in the future. In the image attached for example, an SBU holds 45% of the market's shares.
