the subject under investigation has been electronic learning (e-learning) or electronic education (e-education), specifically concentrating on virtual university. virtual university has been the subject of much debate in recent years. in short, the concept of virtual university denotes a learning/educational system/environment based on internet where higher education is promoted using tools and...

In recent years, with the rise of electric vehicle industry, there has been significant research on charging and power supply technologies for vehicles. terms corresponding converter usage, modular multi-level converters (MMCs) are also increasingly used in field because their unique advantages. However, circulating current problem MMCs not effectively addressed existing domestic international ...

Problems such as high power coupling, low distribution accuracy, and insufficient reactive power-voltage droop accuracy occur when distributed generators are operated in parallel due to the influence of line impedance. The precise control output voltage is difficult achieve using traditional virtual synchronous generator (VSG) control. Taking this into consideration, study proposes a integrated...

BACKGROUND EnSiteNavx electroanatomic mapping system is widely used in radiofrequency (RF) atrial fibrillation ablation, helping the creation of linear lesions. However, the correspondence of the virtual line created by EnSite with the pathological lesion has not yet been evaluated. OBJECTIVE to assess the continuousness of Ensite-guided virtual lines in a swine model. METHODS we performed ...

Stability and robustness are two important performance requirements for a dynamic walking robot. Learning and adaptation can improve stability and robustness. This thesis explores such an adaptation capability through the use of neural networks. Three neural network models (BP, CMAC and RBF networks) are studied. The RBF network is chosen as best, despite its weakness at covering high dimension...

background : along with emersion of the internet, virtual education increasingly has been growing. many studies discussed this method and its impact on learning. present study investigated students’ attitude towards virtual education as well as its effect on learning. methods : this was a pretest-posttest quasi-experimental study. the nursing students, who had selected fluids and electrolyte di...

BACKGROUND Home telemonitoring (HTM) of chronic heart failure (HF) promises to improve care by timely indications when a patient's condition is worsening. Simple rules of sudden weight change have been demonstrated to generate many alerts with poor sensitivity. Trend alert algorithms and bio-impedance (a more sensitive marker of fluid change), should produce fewer false alerts and reduce worklo...

according to the changing business, nowadays teams are cornerstones of successful organizations, in addition, with the developments and technological innovations in communication and information, virtual teams are playing more critical role in today's business. on this basis, determining factors which affect virtual team's performance are important to both scholars and practitioners. ...

although there are many potential benefits associated with the use of virtual product development teams, exploiting these benefits requires an appropriate management. managing virtual product development team is a critical issue as many of these teams fail to accomplish their goals. review of previous literature shows that body of knowledge in managing virtual product development teams is fragm...
