Exact BER performance of asynchronous MC-DS-CDMA over Nakagami-m fading channels [PDF]
, 2008 In this contribution an accurate average bit error rate (BER) formula is derived for Nakagami-faded MC-DSCDMA in the context of asynchronous transmissions and random spreading sequences.

Exact BER of Rectangular-Constellation QAM Subjected to Asynchronous Co-Channel Interference and Nakagami-m Fading [PDF]
, 2006 The exact average bit error ratio (BER) of the rectangular quadrature amplitude modulation (QAM) constellation is studied in the context of asynchronous co-channel interference (CCI) and Nakagami-m fading.

Asynchronous Mappings and Asynchronous Cellular Automata
Information and Computation, 1993 Asynchronous cellular automata are studied. They differ from usual cellular automata by decentralized control structure and by asynchronous performing of actions. Their behaviour is described by trace languages, subsets of partially commutative monoids.

Using a Design Thinking Approach for an Asynchronous Learning Platform during COVID-19
IAFOR Journal of Education, 2021 The COVID-19 pandemic abruptly shut down schools in an urban based school district in the Spring of 2020. As the closures persisted over months, an immediate educational need arose for online curricula that could help alleviate the learning gaps caused ...

Journal of Research in Education Sciences, 2012 本研究結合教師自省與同儕互動之特質，並運用網路具互動性與豐富性之優點，布置一個以數學教學案例為主軸，供國小教師進行非同步線上討論的網路平臺，以探究7 位國小教師在14 週三次教學案例討論的互動過程中，所呈現的溝通模式與互動內涵。蒐集的資料為教師對三次教學案例所進行非同步網路討論的語料。研究主要發現如下：一、藉由非同步網路數學教學案例討論，教師的溝通模式逐漸從「不對稱的互動」走向「對稱的互動」；二、教師互動的內涵亦從「教學策略知識」朝向「數學知識」與「數學教學知識」發展。當教師間的互動型態朝向地位均等的 ...

ONLINE TEACHING. OPPORTUNITIES, CHALLENGES AND RECOMMENDATIONS TO IMPROVE COLLABORATION AND QUALITY OF LEARNING [PDF]
Studia Universitatis Babeş-Bolyai. Psychologia-Paedagogia, 2021 . Remote learning, also known as distance education, can be defined as teaching the students with no face-to-face contact with the teacher in class. Once the Coronavirus spread, globally imposed measures became more and more restrictive leading to ...

Nonverbal Communication in Text-Based, Asynchronous Online Education
International Review of Research in Open and Distributed Learning, 2019 Does nonverbal communication exist in asynchronous, text-based online education? It is commonly believed that it does not due to the absence of body language and paralanguage.

Dynamic asynchronous iterations
Journal of Parallel and Distributed Computing, 2022 Many problems can be solved by iteration by multiple participants (processors, servers, routers etc.). Previous mathematical models for such asynchronous iterations assume a single function being iterated by a fixed set of participants. We will call such iterations static since the system's configuration does not change.
