Systematic literature review techniques and data mining techniques were analyzed in this analysis for the creation of quantitative models of key factors influencing traditional marketing customer behavior in Thailand. The set of data analyzed is focused on the compilation of literature surveys of scholarly literature related to selected correlational studies of both traditional and digital marketing based on theoretical generic consumer stimulus-response model. Techniques that are used described the relationship model are different are described for modeling relationships. The findings of the analysis found that variables influencing consumer behavior were similar and different from traditional and digital marketing experiments. In comparison, research reviews and experiments abroad have also been shown to have the same and distinct influences in analyzing the results of the study. Keywords: Traditional marketing; Digital marketing; Customer behavior; Systematic literature reviews..

Let a pair , X  be functional calculus, where  is a homomorphism from the space of the measurable functions on ,  into the space of all linear bounded operators LB X , X  on a reflexive Banach space X . We define a norm of functional calculus  by    , , ,supL X Xf ff     1 , the convergence of the sequence of functional calculi is a convergence relative to this norm. We study the correspondence between sequences of spectral decompositions, well-bounded operators  n A defined on the reflexive Banach space X , and their correspondence with the theory of functional calculus for such operators. In this article, we establish that if a sequence of the projection-valued measures    ,  nE   I strongly converges to E   ,  I then the sequence   n  of the functional calculi converges to the functional calculus . Results of the article can be employed in t.....

A unique plant from the rainforest of Sarawak, Malaysia, Goniothalamus lanceolatus Miq., was chosen for a phytochemical study based on its ethnomedicinal characteristics amongst the locals. Isolation and purification of a minor compound exhibiting similar retention characteristics was made possible by using preparative Recycling HPLC. Due to a recycle valve in the HPLC system, this method enables the unresolved peaks to recirculate into the column repeatedly until the peaks were successfully separated as pure entity. During the recycling process, solvent consumption is not needed. Recycling HPLC expediates the isolation and purification of complex mixtures in such a sustainable way. One styryl lactone was successfully isolated and identified as 6S,7S,8S-(-)-goniodiol. Keywords: Recycling HPLC, Goniothalamus, Goniothalamus lanceolatus..

Feed formulation is important in ensuring the quality of livestock production and sustaining the self-sufficient of the livestock industry in the country. Currently, local farmers have been feeding their lambs with goat pellets and this has caused an imbalance between nutrient feeding in lambs. In this study, a modified linear programming (LP) model is proposed to optimize a specific lamb feed formulation that satisfies the nutrient requirement at a minimum cost. The dietary nutritional requirements for lambs were derived from the standard criteria of the 1985 National Research Council. The modified LP model considers the nutrients needs of lambs according to their weight, the amount of nutrients to be consumed and the cost of each feedstuff. This study focuses on obtaining the optimal amount of feedstuff in the lamb feed that is determined based on the solution of a modified model. The analysis of the resulting price of goat pellets available in the local market was performed. The res.....

Images and metaphors have a significant impact on the mathematical knowledge of indigenous students. Several studies on indigenous education have found that indigenous students have very different ideas about learning mathematics. In this regard, research on images of mathematics and metaphors related to mathematics learning held by indigenous students is considered distinct and novel in relation to past research. The purpose of this case study is to investigate the mathematical images and metaphors in Pahang, Malaysia. A purpose-sampling technique was used to collect data digitally and descriptive analysis was performed on the responses of 31 indigenous students. The use of images and metaphors as constructions gives a glimpse into how students view themselves as mathematics learners and what they do while learning mathematics. Furthermore, images and metaphors help to construct meaning for abstract mathematical concepts because they connect to a variety of different senses. The findi.....

The majority of fuzzy time series forecasting (FTSF) algorithms assess forecasting accuracy using an error-based distance. The predicted value is defuzzified to a crisp number and the error-based distance will be computed. Defuzzification causes some information to be lost, which leads to its inability to comprehend the level of uncertainty that has been preserved during the forecasting process. This paper proposes an enhanced FTSF model with forecasting accuracy developed based on a new hybrid similarity measure combining the centre of gravity and area and height. Three properties of the hybrid similarity measure are presented. The FTSF model is implemented in the case of the Malaysian unemployment rate. The findings indicate that, on average more than 94% of the predicted value was identical to historical data. The forecasting accuracy is produced directly from the forecasting value without undergoing the defuzzification process, which can preserve some information from being lost. .....

A mathematical model known as Geometric Brownian motion has proven to be an effective tool that can be deployed to forecast the price of goods in the future due to the presence of random terms, which represent the stochastic or random fluctuation of prices over a given period of time. The success of this model revolves around the estimation of its governing parameters. To efficiently predict the price of goods, using the Geometric Brownian Motion model (GBM), one needs to determine the value of returns and use the calculated returns to estimate the value of drift as well as volatility. This research used the value of volatility and drift terms obtained from real data of sugar in the months under review. The method has shown to be very reliable in capturing the intelligent trend in the price of sugar in Malaysia. The model was able to stimulate the pattern of the predicted price that shares a great resemblance to the actual price of sugar. The result obtained is very encouraging and pla.....
