Classroom learning behavior recognition can provide effective technical support for teaching and learning. However, in natural classroom scenarios, behaviors are often missed or falsely detected due to character occlusion the small object. To tackle above issues, this study proposed an improved algorithm (YOLOv8n_BT) based on YOLOv8n. On one hand, problem of behaviors, incorporated BRA into Backbone better capture feature information; other object back-row-students, expanded a Tiny Object...
Thermal management using a vapor-liquid two-phase circulation system is challenging in compact and complex-shaped electronic devices. In this study, we design fabricate heat pipe that can adapt to various shapes, regardless of space constraints. The capable bending or twisting three dimensions, making it suitable for devices arbitrary shapes. It effectively transfers from in-plane chips out-of-plane spaces through flexible pathways. This cycle achieves an ultra-high thermal conductivity up...
ABSTRACT Over the last few decades, many studies have explored uses of virtual reality (VR) or augmented (AR) in different disciplines and examined their effects on learning. However, effectiveness VR AR students' learning is still inconclusive, within specific domain higher engineering education not been extensive detail. The aim this article to systematically examine overall effect outcomes by meta‐analyzing results 35 comparative from 24 high‐quality journal papers published between 2013...
Cilia are fundamental functional structures in natural biology. As the primary option of artificial cilia, magnetic cilia have been drawing extensive attention due to their excellent biocompatibility, sensitive response, and contactless actuation. However, most ordered fabricated by molds, suffering from high cost low efficiency. In this paper, an ultrafast fabrication method array using micro-cavity inducing effect was proposed. With impact static dynamic fields, fine were first formed...
Despite the continuous emphasis on emotion in multimedia learning, it was still unclear how pedagogical agent emotional cues might affect learning. In present study, a between-subjects experiment performed to examine effects of with dual-channel learners' emotions, cognitive load, and knowledge transfer performance. Participants from central Chinese university (age mean = 21.26, N 66) were randomly divided into three groups. These groups received instructions an affective agent, neutral or...
Abstract Background Both socially regulated learning and cognitive quality are important factors affecting collaborative knowledge building, but the current research lacks a joint quantified evaluation method that combines these two aspects. Objectives Based on existing framework, we proposed for in further extracted indicators. Methods This study involved 74 learners enrolled course named ‘the Application of Modern Educational Technology’ as subject study, made case analysis with this...
Main content extraction of web pages is widely used in search engines, aggregation and mobile Internet browsing. However, a mass irrelevant information such as advertisement, navigation trash included pages. Such reduces the efficiency processing content-based applications. The purpose this paper to propose an automatic main method In method, we use two indicators describe characteristics pages: text density hyperlink density. According continuous distribution similar on page, estimation...
Emotion recognition is an important component of affective computing, and significant in the implementation natural friendly human-computer interaction. An effective approach to recognizing emotion from text based on a machine learning technique, which deals with as classification problem. However, recognition, texts involved are usually very short, leaving large, sparse feature space, decreases performance classification. This paper proposes resolve problem sparseness, largely improve short...
Kavalactones, mainly found in Piper methysticum, are a class of lactone compounds usually with an arylethylene-pyrone skeleton.Till now, fifty-one kavalactones have been isolated from the genera Piper, Alpinia, Amomum, Polygala, Goniothalamus, and Dumortiera.The bioactivities six kavalactones, kawain, 7,8-dihydrokawain, methysticin, dihydromethysticin, yangonin, desmethoxyyagonin, studied extensively.This review aims to give overview plants their various bioactivities.
In recent years, with the rapid progress of game development technology as well human-computer interaction technology, game-based learning (GBL) has not only drew attention increasing number researchers but this method also been implemented into classrooms by teachers around world. And improvement for knowledge acquisition is being reported most frequently occurring outcome GBL across a wide range subjects like mathematics, physics, health etc. However, there are very limited cases where...
Educational game is a certain computer games that can develop the user's knowledge, skills, intelligence, emotion, attitude, values. Kinect listen to voice of people and observe people's action through skeleton tracking technology speech recognition which make it easier communicate with computer. By analyzing key existing education games, we find application on rarely. This paper makes full use advantages characteristics design serious model based Kinect. The working principle definition...
XML is widely used in development of educational resources database system (ERDS) because its natural traits: easy-to-interpreted, criterion-opened, extensive, cross-platform compatible. But there are some limitations naturally when we use the relational to store and search data. SQL SERVER 2005 ASP.NET 2.0 provide stronger function support XML. Through analyzing criterion, functions structure about ERDS, this paper gives us a solution ERDS based on 2.0. Also discusses technology realization...
Massive Open Online Courses (MOOCs) are platforms teachers can use to seek guidance on different strategies update their teaching skills. This study finds the effectiveness of MOOCs in developing professional performance and skills school teachers. It tries show extent which benefit from these courses how they apply them practical teaching. A mixed-method sequential explanatory (following up quantitative findings with qualitative ones) method by using multiple data sources, including MOOC...
