Applying a Topical Relevance Typology to Analyze Online Product Information Types and Their Effects on Internet Consumer Decision

This paper lays out a research proposal of systematically analyzing and comparing the decision effects of online product information types. Hardly any in-depth knowledge is currently available on how different information types influence online consumer trust and purchase intention. To address this research gap, we apply a generic function-based topical relevance typology to classify the variety of online product information and plan for focused comparisons of the functional roles played by different information types in e-retailing. Understanding the differential impacts of each information type provides a basis for prioritizing online information provisioning and organization, which becomes particularly meaningful in the current context of information overload. The paper briefly reviews information research in e-commerce, introduces the product type as an important moderating factor, and discusses the conceptual basis and applicability of applying the generic relevance typology to analyze product relevant information. The research model and preliminary hypotheses are also described

Location Analysis of Chain Supermarket Distribution Center Based on CFLP

The number of stores operated by chain supermarkets is large, and the distribution of goods has the characteristics of low delivery volume and multiple delivery times. Logistics transportation costs account for a large proportion of operating costs. Establishing distribution centers is an effective measure to reduce operating costs. Through large-scale distribution, the chain supermarket distribution center can centrally manage the inventory of goods and distribute them to each store, thereby improving the distribution efficiency. This paper analyzes the influencing factors of the location of chain convenience supermarket distribution center, and then qualitatively analyzes the actual situation of the location object, determines the initial location plan, and establishes the CFLP model to solve the problem of the location selection of the chain supermarket distribution center

Towards More Authentic Heritage Destination Experiences

Heritage destinations have a significant responsibility to visitors. In countries like China, where heritage plays a significant role in a person\u27s identity, such destinations offer visitors an opportunity to develop a deeper sense of self. For this reason, they need to be authentic, but so do the visitors. UCF Rosen College of Hospitality Management researcher Dr. Xiaoxiao Fu joined a team of experts based in China to identify how the perceived authenticity of two of China\u27s most revered heritage sites affects visitors\u27 personal sense of authenticity, their wellbeing, and how memorable they found their visits

Multimodal Spatial Calibration for Accurately Registering EEG Sensor Positions

This paper proposes a fast and accurate calibration method to calibrate multiple multimodal sensors using a novel photogrammetry system for fast localization of EEG sensors. The EEG sensors are placed on human head and multimodal sensors are installed around the head to simultaneously obtain all EEG sensor positions. A multiple views’ calibration process is implemented to obtain the transformations of multiple views. We first develop an efficient local repair algorithm to improve the depth map, and then a special calibration body is designed. Based on them, accurate and robust calibration results can be achieved. We evaluate the proposed method by corners of a chessboard calibration plate. Experimental results demonstrate that the proposed method can achieve good performance, which can be further applied to EEG source localization applications on human brain

Numerical simulation study on pore clogging of pervious concrete pavement based on different aggregate gradation

Pervious concrete (PC) pavements can effectively reduce surface runoff, but it will be clogged with time and its service life will be affected. In this study, based on three groups of PC specimens with different aggregate gradations optimized by previous experiments, the pavement-clogging simulation test is carried out using the two-way coupling of the particle flow code with computational fluid dynamics (PFC-CFD). The results show that when the gradation of aggregates in the pervious pavement is different, the volume fraction of clogging material in the pavement and the time when the volume fraction of the clogging material reaches the maximum are also different. It is related to the zigzag degree and size of the pore in the pervious pavement. The smaller the particle size of coarse aggregate in the pervious pavement, the easier it is to be clogged, and the discontinuous graded coarse aggregate has a good shielding effect on the clogging material. Different clogging material gradations have different effects on the clogging of pervious pavements. According to the aforementioned research results, researchers can select different mix ratios of anti-clogging PC according to different areas of use. The law obtained from the experiment can provide a reference for further study of the double-layer pervious pavement structure design

Transient and non-uniform heat flux effect on solar thermoelectric generator with phase change material

Transient and non-uniform heat flux from solar concentrators can affect the performance of solar thermoelectric generators, which generate electricity from concentrated solar radiation. Therefore, this paper presents a detailed three-dimensional study on the effect of transient and non-uniform heat flux on the performance of a solar thermoelectric generator (STEG). COMSOL 5.4 Multiphysics software is utilized for the numerical study while the non-uniform heat flux from a compound parabolic concentrator is obtained through ray tracing simulation using Lighttools software. Varying solar radiation under typical partly cloudy weather condition is utilized. Furthermore, phase change material (PCM) is used to reduce the effect of transient and non-uniform heat flux therefore; it is positioned at the top surface of the solar thermoelectric generator. A comparison between the performance of the STEG with and without PCM is presented, and a parametric study on the effect of PCM fins and PCM height on the STEG performance is carried out. Results show that the place of PCM on the top surface of the solar thermoelectric generator is an effective approach to provide a stable electrical performance form the STEG under varying weather conditions. Furthermore, results reveal the effectiveness of the phase change material in protecting the solar thermoelectric generator under highly concentrated solar radiation. This study will provide valuable design guidance for solar thermoelectric generators under varying weather conditions and with solar concentrators, which produce non-uniform heat flux
