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.
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:
In marketing and advertising, frequency refers to the number of times a target audience is exposed to a particular message or advertisement within a given time frame. [1] This concept is a fundamental element of marketing communication strategies, aiming to enhance brand recall, create awareness, and influence consumer behavior through repeated ...
The mixer circuit can be used not only to shift the frequency of an input signal as in a receiver, but also as a product detector, modulator, phase detector or frequency multiplier. [6] For example, a communications receiver might contain two mixer stages for conversion of the input signal to an intermediate frequency and another mixer employed ...
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]
