Conceptual profiling practice

The expedited procedures described herein provide a practical and cost effective means of conceptual profiling and consequently for obtaining a derived index of fit-to-brand, within the context of routine new product development. 

The practical considerations involved in conceptual profiling and the associated analysis tools developed by the author and his colleagues at MMR Research Worldwide are described in detail in a suite of recent, peer-reviewed scientific publications (Thomson, et al, 2010 Crocker and Thomson, 2014 Thomson and Crocker, 2014). 

For practical purposes, there are two aspects to conceptual profiling fhat need to be considered separately concept description and quantification of degree of conceptual association. 

Notwithstanding the practical difficulties experienced in obtaining the conceptual profiles for (unbranded) SMSW liquids, this case study illustrates the speed and efficiency of MMR s Bullseye quantification procedure and the simphcity of using correlation between product and brand conceptual profiles as a derived index of fit-to-brand. 

Symmetrically shifted pulses have been proposed as a means of solvent suppression. Symmetrically shifted pulses are symmetrically shifted laminar pulses that contain equal numbers of rectangular pulse components of the same phase at an offset frequency. The basis of the symmetrically shifted pulse family is the SS pulse which is conceptually equivalent to applying simultaneous ir/2 rectangular pulses with two separate, but in-phase, transmitters at offset frequency from the water. On a practical basis an SS pulse is obtained by a complete Itt cosine modulation of a single transmitter (see Fig. 15). An S pulse is half of an SS pulse (i.e. a half-cycle tt pulse) which results in a narrower null and a 180° phase inversion at the transmitter frequency. They are also the soft, continuous equivalent of binomial sequences. The SS and S pulses have broader excitation maxima than the sinusoidal profile of the JR sequence. The method has maximal excitation at an offeet frequency of second-order U-shaped water suppression. The exdtation profile is related to the maximum amplitude modulation and can be determined by numerical evaluation of the Bloch equations. Hence a new pulse shape must be used for each excitation window. The SS pulses give better water suppression than the JR sequence, but at the expense of poorer excitation of resonances closer to the water. Also, there is no phase inversion at zero frequency. The S pulse gives better excitation near the water frequency but with less water suppression. 

Several models have been developed in the last decade aimed at describing the emission of volatile organic compounds (VOCs) from indoor materials. These models may be broadly distinguished with respect to their conceptual background (physical-mass transfer models and/or empirical-statistical models) as well as their ability to describe different emission profiles. Physical models are models based on principles of physics and chemistry, whereas the empirical models do not necessarily require fundamental knowledge of the underlying physical, chemical and/or biological mechanisms. Many models used in the indoor air quality field in practice are hybrid models, in which aspects of both physical and empirical approaches are combined. 

Here we show that the neutron reflectivity method combined with contrast variation allows us, in principle, to determine as precise as we wanted. Practically, however, the collimation imperfection reduces the resolution to a level which is unsatisfactory, but can be improved. Perhaps, the major interest in the method is conceptual.Using the onedimensional Schrodinger equation to predict the reflectivity, we have to consider the concentration profile as a smooth interaction potential. This point of view is fruitful,and we shall adopt it in this paper.
