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 ...
RFM is a method used for analyzing customer value and segmenting customers which is commonly used in database marketing and direct marketing. It has received particular attention in the retail and professional services industries. [1] RFM stands for the three dimensions: Recency – How recently did the customer purchase?
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.
The marketing research process is a six-step process involving the definition of the problem being studied upon, determining what approach to take, formulation of research design, field work entailed, data preparation and analysis, and the generation of reports, how to present these reports, and overall, how the task can be accomplished.

Quantitative marketing research is the application of quantitative research techniques to the field of marketing research.It has roots in both the positivist view of the world, and the modern marketing viewpoint that marketing is an interactive process in which both the buyer and seller reach a satisfying agreement on the "four Ps" of marketing: Product, Price, Place (location) and Promotion.
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 ...
Later research by Xie et al. showed the existence of another type of grating with similar thermal stability properties to the type II grating. This grating exhibited a negative change in the mean index of the fiber and was termed type IIA. The gratings were formed in germanosilicate fibers with pulses from a frequency doubled XeCl pumped dye laser.
Journal of Marketing Research is a bimonthly peer-reviewed academic journal published by the American Marketing Association. It was established in 1964 and covers all aspects of marketing research. [1] [2] [3] According to the Journal Citation Reports, the journal has a 2020 impact factor of 5.000. [4] The founding editor was Robert Ferber.
