Abstract: This study presents a global digital marketing framework, developed through a case study of a UK-based B2B industrial flooring company and the review of relevant literature, focusing on enhancing its Southeast Asian market presence. Using a mixed-method approach, it combines qualitative and quantitative analyses to examine digital marketing strategies, trends, and competitor practices. Findings highlight the effective use of social media by leading competitors and emphasize the importance of digital marketing in optimizing B2B operations and cross-cultural interactions. The study recommends some actionable insights for companies aiming to remain competitive and grow in the dynamic market.

Abstract: The geometric dimension error of plastic parts is one of the common defects in plastic injection molding (PIM). The main reason for this defect is the uniformity of the cooling of the molten plastic. The conformal cooling channel is widely used in injection mold processing due to its excellent cooling effect. However, complex injection molding processes can affect the quality of plastic parts. An optimization model for injection molding process parameters was proposed based on Grey Relational Analysis (GRA) and Response Surface Methodology (RSM). Seven important molding parameters were determined, including injection time, holding pressure, mold temperature, injection pressure, holding time, melt temperature, and mold opening time. The X, Y, and Z directions of plastic part warping deformation were selected as quality indicators. An L18 orthogonal design experiment was established based on the signal-to-noise ratio, calculated the grey relational coefficient and relational degree, and conducted the qualitative analysis to screen and evaluate the influencing factors with high relational degree of holding pressure, holding time, and melt temperature. A second-order polynomial regression model was established using RSM, and a quantitative analysis of warping deformation was conducted. The results showed that when the holding pressure was 110 MPa, the melt temperature was 250 °C, the mold opening time was 6 seconds, the X, Y, and Z direction warping deformations of the optimized product were 0.4354 mm, 0.1411 mm, and 0.2951 mm, respectively, which were reduced by 51.60%, 43.67%, and 45.02% compared to before optimization. The research results have verified the accuracy and reliability of the optimization of injection mold process parameters derived from qualitative and quantitative analysis. It is worth noting that this method has significant advantages in qualitatively identifying the primary and secondary relationships between different conditional parameters and quantitatively determining the optimal combination level for each parameter. This method will provide a framework for optimizing the design parameters of injection molding processes and improve the efficiency of identifying the optimal target combination.

Abstract: Two main factors influence the protective effect of the silane building protective agents, that is, the molecular structure and the content of the active component. In this paper, qualitative and quantitive analysis of the active component in silane building protective agents were studied. Firstly, Gas chromatography-mass spectrometry (GC-MS) is employed to identify the active component in unknown sample, according to its mass spectrum and retention time. Secondly, Gas chromatography (GC) is applied to determine the content of the active component in unknown sample. Results show that the mass spectrum of the active component in unknown sample is similar with that of n-octyl triethoxy silane and (2,4,4-trimethylpentyl) triethoxy silane. The retention time of the active component in unknown sample is 16.5 min, which is the the same as that of (2,4,4-trimethylpentyl) triethoxy silane. Nevertheless, the retention time of n-octyl triethoxy silane is 17.6 min. So the active component in unknown sample is identified as (2,4,4-trimethylpentyl) triethoxy silane, and its content is determined as 82.0% on the basis of GC method with isobutyl alcohol as the internal standard.

Abstract: The paper analyzes a variety of reasons differential fault automobile differential and establishes the corresponding fault tree by using Fault Tree Analysis of reliability theory. The failure spectrum of automobile differential is constructed through qualitative analysis of the fault tree. Meanwhile the study gives the theoretical methods about the solving of top event’s probability and bottom event’s importance for design, fault diagnosis and repair of automobile differential.

Abstract: Efficient method was proposed for the qualitative detection of 6 illegal sweeteners in commercial liquor and wine by laser Raman spectroscopy. The method was based on the comparative analysis of Raman spectrogram of pure sweeteners and alcohol samples. For the 6 kinds of sweeteners tested, saccharin sodium, acesulfame potassium impurity and cyclamate, were present as additives in the samples. The results showed that the proposed method was fast and simple with high repeatability and sensitivity, and needed little samples and cost less.

Abstract: The main building of the Hubei press has a horizontal contacting passageway in the middle of two buildings in the fifteenth floor, which has attractive appearance and like a doctorial hat from afar. The structure is reasonable and more stable with the diagonal bracing and the beam. Analysis and research in this paper can provide reference for the design of this structure.

Abstract: Far-infrared fiber can promote blood circulation, accelerate microcirculation and thermal insulation.It also has a very strong effect for health care. In view of these functions, far-infrared fiber has industrialization, and widely used in clothing, bedding. But it has no unified method for far-infrared fiber qualitative analysis. This paper briefly describes the basic content of the Near-infrared Spectroscopy technology.Use Shanghai Lengguang S400 near-infrared quality analyzer , using Near-infrared spectroscopy technology and using PLA method to establish the far-infrared polypropylene qualitative model and the far-infrared polyester qualitative model.This method can rapidly and accurately to do qualitative analysis of far-infrared fiber.

Abstract: with the rapidly development of modern education, the degree of integration of information and modern education has been strengthen continually. The new education model of information technology and modern education is related with traditional education. They are complete and mutually promote in the teaching process. This paper analyzes the basic connotation of psychology teaching. Based on the principle of teaching and research mission of the psychology, this paper profiles psychology teaching feedback and coupled revelation of information communication model. This paper establishes psychology teaching multi-dimensional interactive model of the IT environment using the qualitative analysis method. This paper determines the effectiveness of teaching effectiveness through the effectiveness of the computer information entropy which provides a theoretical basis and practical guidance for the psychology teaching reform and innovation.

Abstract: According to the related concepts and theory of Kansei Engineering (KE), this paper kansei analyzed the shape of household scales by using AHP (analytic hierarchy process), aiming to conclude the relation between emotional intention and design considerations, and sequentially to provide significant design basis and references for product development. Mathematical methods, such as statistics, were applied to this study, which provided a fresh idea for the early stage research of product design.

Abstract: In recent years, food safety problems have emerged frequently in China. Fake and poor quality food and the indiscriminate use of additives are to be blamed. However, out-dated cold chain logistics is the more important reason. If the cold chain conditions are not good, the food will deteriorate through long-distance transportation, which will cause food safety problems when they are sold to the final consumers. Cold chain logistics is a major food safety measures. In Chins, through the production, circulation and consumption of cold fresh food, out-dated cold chain not only causes a great economic loss but also threatens food safety .Based on the SWOT analysis, this thesis studies Chongqing agricultural products cold chain logistics development strategy in both qualitative and quantitative aspects in order to better provide directions for the policy makers.
