Carbon emission reduction and achieving carbon neutrality has become an inevitable trend in the sustainable development era. We investigate manufacturer’s encroachment decisions considering government cap-and-trade regulations consumers’ low-carbon preference. The equilibrium for four scenarios are analytically obtained compared based using Stackelberg game. A comparison with without regulation under two regarding member’s profits levels conducted. It is shown that decision always...

Purpose The purpose of this paper is to figure out the exact knowledge demand makers. Furthermore, aims construct space based on makers’ demand. Design/methodology/approach first step research explore by methods field investigation, non-interventional study and in-depth interviews. On that basis, elements, principles, framework mechanism were discussed. grounded theory NVivo software used in data analysis. Findings investigation shows interest competition are main motivations for findings...

Purpose Contract Manufacturers (CM, factory) can cultivate factory brand products by imitating Original Equipment Manufacturers' (OEM, owner) National Brand products, and compete with OEM through the online retailer, that is, encroachment. In practice, few consumers identify quality of those two in market. Implementing blockchain technology (BTI) help all product but may change operation decisions incur implementation costs. This study aims to explore how will BTI strategies affect...

Shape blending is of great theoretical and practical significance in industrial design, engineering simulation, etc. An approach to 3D shape using point cloud slicing proposed this article. It can be used design as an aid creativity. After the uniform each model, improved ray-firing method adopted establish correspondence between vertices on two sets cross-section contours. The vertex coordinates intermediate shapes are generated weighted mean methods, new contours created. Finally, model...

The keypoint detection and its description are two critical aspects of local keypoints matching which is vital in some computer vision pattern recognition applications. This paper presents a new scale-invariant rotation-invariant detector descriptor, coined, respectively, DDoG FBRK. At first the Hilbert curve scanning applied to converting two-dimensional (2D) digital image into one-dimensional (1D) gray-level sequence. Then, based on 1D sequence, an approximation DoG using second-order...

Based on the existence of higher order mode waves (HOMW) in expansion mufflers is proved theoretically, a 3-D FEM used to obtain four-pole parameters muffler which are turn calculate transmission loss. With this method, distribution sound pressure calculated, effects HOMW performance investigated and technique improve put forward. It shown that, because HOMW, wave chamber not plane form; can descent capability muffler, position inlet outlet important mufflers.

Purpose Spatial olfactory design in the library appears to be a practical approach enhance coordination between architectural spaces and user behaviors, shape immersive activity experiences experiences. Therefore, this study aims explore association elements of space users’ perception, providing foundation for libraries. Design/methodology/approach Using perception semantic differential experiment method, collected feedback on emotional experience stimuli from 56 participants an academic...

Abstract This research focuses on art works depicting the history of Cuban Red Revolution as its primary subject. It endeavors to illuminate narrative by analyzing these works. Additionally, it aims create an ontology-based knowledge resource dedicated dissemination associated with Revolution. The intention is systematically organize and visually represent embedded in that explore outcome this includes a metadata framework, ontology specifically Revolution, graph. These components...

A usable website is a key to ensuring user satisfaction whiles an unusable brings about frustration and dissatisfaction.Usability testing has been identified as great way check how products are users.This however ignored by many designers during the designing stage of such websites.This in long run makes experience difficulties, errors, because product was not created with needs mind.Usability explore users also identify problems challenges that encounter while using product.Involving...

The entry of the humanities into digital era characterizes prominence two dimensions technology and humanity, highlighting trend their mutual intersection integration. traditional research paradigm humanists has been transformed. Based on literature semistructured interviews, this study adopts a grounded theory approach to identify academic competence in China finds it is composed information acquisition competence, application sharing competence. On basis previous research, paper uses...

Extracting and transforming shape features has been an important research domain in wheel hub design. The study of design based on semantics, brand planning, structural optimization requires regression analysis by using the corresponding variables to guide through correlation model. practical role feature transformation is determined its effectiveness, accuracy, convenience. This process, however, generally handled manually previous studies, limiting universality comprehensiveness outcomes....

This research extends the design concepts and methods of user journey maps to field intangible cultural heritage, selects typical lotus lantern material package in Qinhuai lanterns as an example explore digital experience lanterns. On-site are used understand users, define target users build personas. AEIOU recording framework is record behavior, analyze reorganize behavior with card classification, summarize flow. The Likert Smiley Scale ask children evaluate specific behaviors, get...

Design sketch is at the core of product design process. How to use express concepts and develop creative thinking, key point in teaching. Firstly, definition, classification function are explained. Secondly, its importance process analyzed. Then compared with computer rendering. The uncertainty presented reveal ambiguity. Thirdly, relationship between ambiguity thinking discussed. Finally, teaching points proposed from two aspects presentation techniques training contents. Appropriate...

Research data management (RDM) practices in China are underdeveloped despite the release of RDM policy on 2 nd April 2018 and research to unearth these challenges cannot be overemphasized.The objective this study is investigate relationship among critical stakeholders specifically from librarians' perspective speed up agenda for maximum benefit.This used Structural Equation Modeling (SEM) RDM.The findings revealed that relationships different significantly positive, institutions mediate...

A particle filter is a powerful tool for object tracking based on sequential Monte Carlo methods under Bayesian estimation framework. major challenge in how to allocate particles high-probability density area. does not take into account the historical prior information generation of proposal distribution and, thus, it cannot approximate posterior well. Therefore, new fuzzy grey prediction-based (called FuzzyGP-PF) proposed this paper. First, prediction model which was mathematics theory and...

Particle filter is a powerful tool for moving target tracking based on Sequential Monte Carlo methods. But particle doesn't take into account the historical prior information generation of proposal distribution, and then it cannot approximate posterior density well. A new frame (called FGP-PF) proposed in this paper. Firstly, prediction model which was fuzzy mathematics theory gray system established, coined FGP (Fuzzy-Grey-Prediction) model. Secondly, history state sequence utilized as to...
