The use of Unmanned Aerial Vehicle (UAV) swarms is increasing in many commercial applications as well as military applications (such as reconnaissance missions, search and rescue missions). Autonomous UAV swarm systems rely on multi-node interhost communication, which is used in coordination for complex tasks. Reliability and low latency in data transfer play an important role in the maintenance of UAV coordination for these tasks. In these applications, the control of UAVs is performed by autonomous software and any failure in data reception may have catastrophic consequences. On the other hand, there are lots of factors that affect communication link performance such as path loss, interference, etc. in communication technology (WIFI, 5G, etc.), transport layer protocol, network topology, and so on. Therefore, the necessity of reliable and low latency data sharing mechanisms among UAVs comes into prominence gradually. This paper examines available middleware solutions, transport layer protocols, and data serialization formats. Based on evaluation results, this research proposes a middleware concept for mobile wireless networks like UAV swarm systems.

This study introduces the experience of a project-based learning (PBL) approach for first-year engineering students at German-Mongolian Institute for Resources and Technology (GMIT), Mongolia. The engineering project course at GMIT is the first-ever PBL experience for engineering curriculum in Mongolia and adapted from the engineering program at the Technical University of Darmstadt and has been implemented since 2014. It is dedicated to preparing students for gaining both technical and soft skills through PBL from the beginning of their engineering education. The questionnaire surveys are taken regularly during the course period from students to improve the course quality. The current study presents the analysis of questionnaire surveys done in 2019 and discusses the benefits and challenges of the course. The responses by students revealed that the implementation of the course was beneficial in improving teamwork. Suggestions based on the PBL are given to improve the effectiveness of engineering education in Mongolia.

The problem of speaker separation is an established field in science and goes back to the cocktail party problem defined in 1953. For decades, methods have been improved and developed, but the computational complexity is rarely considered just as the possibility to use hardware acceleration mechanisms. For this reason, this paper addresses the research question: how speaker separation can be realized on embedded systems by exploiting parallelization and intelligent hardware/software partitioning. For this purpose, a concept is described which uses an FPGA for parallelization to separate a speech signal from an intended direction providing a constant throughput rate. The implementation results show the independence of FPGA resources except BRAM size, proving the scalability of the concept, just as the real-time capabilities.

The increasing attention to artificial intelligence technologies in daily life and the need to consider it as a priority topic for students in the twenty-first century clearly leads to artificial intelligence (AI) integration in higher education. Therefore, university teachers must be properly prepared to use AI in their teaching for successful integration. In this study, the researcher aimed to survey to investigate Bangladeshi university teachers' attitudes toward AI as a teaching tool. The survey results showed that teachers have minimal understanding of Artificial Intelligence and its assistance in the classroom. However, they considered it as an educational possibility. The findings indicated that teachers require assistance to be effective and competent in their teaching practices; the findings suggested that AI has the potential to contribute as an assistant.

The data volume handled by wireless sensor networks (WSN) is ever growing due to increasing node counts and node complexity – be it in traditional WSN applications or for Car2X or Internet-of-Things. Queriable WSN are a concept to handle the large data volumes in such networks by abstracting the network as a virtual database table to which users can pose queries. This declarative approach enables networks which can flexibly adapt to changing application requirements. In addition they possess a flat learning curve since users do not need to have a high technological understanding of the sensor node firmware. Upon executing a query it is first propagated through the network and once it has reached the desired nodes, results are collected and send back through the query-posing node (usually the sink). The routing which is used for the data aggregation step plays a major role in the energy efficiency in networks with increasing node and sensor value counts as represented by Car2X networks for instance. In this paper, an ad-hoc routing strategy for queriable WSN is proposed which is both energy-aware and application-specific. It will be shown that this routing can contribute greatly towards decreasing the energy consumption needed for data aggregation and thus helps increasing the network’s lifespan.

Artificial Intelligence (AI) has potential to change the tasks that are currently being done by Human being. The Internet of Things (IoT) has potential to increase Medical Device connectivity, enabling more immediate information sharing and coordination between doctors and patients. Virtual reality (VR) has potential to enhance medical training. Digital Health technologies have the power to expand coverage of healthcare (access), enhance services (quality) and reduce/optimize resources (cost). Affordability, infrastructure, and human capability limits overall impacts of Digital Health technologies and must be addressed. Therefore, capacity building through strategic alliances and partnerships remains crucial in harnessing the promises of Digital Health Technologies. This paper summaries challenges in the implementation of Digital health Solutions among African health systems and enumerate the possible ways of addressing the identified challenges. Keywords— Artificial Intelligence (AI), Internet of Things (IoT), Virtual Reality (VR) Digital Health, Remote Patient Monitoring RPM), Robotic Process Automation (RPA)

Universities' goal in the twenty-first century is threefold: knowledge generation, utilization, and sharing. In education, students are clients who pay to interact with institutions in order to gain knowledge and skills. To boost national competitiveness, university education should be the primary system for training and equipping people to be highly skilled, creative, inventive, and professional. As a result, assessing the quality of education services becomes critical. The study topic in this context will be how to adequately quantify service quality while taking cultural factors into account. This research will employ SERVQUAL and HOFSTEDE dimensions to explore the two concepts of service quality and culture because they are the most widely used models in their industry. The key research issue based on this problem is how culture effects service quality in a certain service context and how service quality expectations fluctuate across different types of service contexts and cultures. With the rise of online education caused by the covid19 pandemic, students from different countries and diverse cultural backgrounds seek to learn from university or instructors located in other parts of the world. These university and instructors need to understand learners’ cultural differences to provide quality education services. This makes the link between culture and service quality expectation of utmost importance. In the case of education context, Power distance has a stronger correlation with reliability and assurance. The following conclusions can be drawn from this: Mongolia has a high "power distance" culture, therefore, in the field of Mongolian education, graduates are trained to be skilled professionals, as well as job security and demand for graduates is important.
