Analysis of the characteristics of agricultural product price volatility and trend forecasting are necessary to formulate and implement agricultural price control policies. Taking wholesale cabbage prices as an example, a multiple test methodology has been adopted to identify the nonlinearity, fractality, ...
Moreover, for pets, the specificity of the animal needs to be considered in the risk evaluation as, for example, the jaws of an adult dog will certainly have a different effect on an object than the jaws of a kitten. As part of the hazard analysis carried out during the development ...
For a minimal example, consider a sum over m numbers taking values \(\pm 1\). In the worst possible scenario, they could all share the same sign and add up coherently. However, if the numbers have random signs independent of each other, the total strength is usually much smaller $$\...
(2)Rt=exp−∫0tλt′dt′ We substitute Eq. (1) into Eq. (2) and integrate over the time. Then, we obtain (3)Rt=exp−tαβ This is equal to the Weibull distribution with α as the scale parameter and β as the shape parameter. Fig. 1 shows an example of Weibull distributio...
In the second step, a simple frequency analysis was done from a consumer survey to extract frequently used affective expression. The third step was to extract primary tasks for mobile phones and to perform an experiment or a survey for the evaluation of mobile phones using those tasks the ...
First, the NYTS has changed use questions for a few products over time; for example, bidis and kreteks were not included in the survey after 2011. Second, we did not include pipe smoking owing to a lack of data on past 30-day use. Neither of these changes should affect our findings...
The demand rate is a function of time, appreciation period, customer relationship management cost, and frequency of advertisements (see, for example, Cheng and Wang [6], and Rabbani et al. [29]). The demand rates of different stages are as follows: (1.1) Product introduction stage: The ...
Here’s an example: “(STAKEHOLDER) needs a way to___(PROBLEM/NEED) because ___ (INSIGHT)" This stage will help the designers identify features, functions, and other elements that should be included in the product to address users' main pain points - or, at least, make it easier for...
For example, the higher selectivity towards CH4 in the thermocatalytic reactions on Rh has already been ascribed to its higher Eads,O (ref. 61), while the exclusive selectivity for CO on the Au photocatalyst was caused by the low Eads,O and the deficiency of surface H atoms under our ...
these design parameters can help designers clarify the type and degree of interactions between components and improve the accuracy of interaction analysis in the TRIZ function model. Furthermore, the information of the product’s working environment is also reflected in DT, which will help to recogni...
