E-learning in the Cloud Computing Environment: Features, Architecture, Challenges and Solutions
The need to constantly and consistently improve the quality and quantity of the educational system is essential. E-learning has emerged from the rapid cycle of change and the expansion of new technologies. Advances in information technology have increased network bandwidth, data access speed, and reduced data storage costs. In recent years, the implementation of cloud computing in educational settings has garnered the interest of major companies, leading to substantial investments in this area. Cloud computing improves engineering education by providing an environment that can be accessed from anywhere and allowing access to educational resources on demand. Cloud computing is a term used to describe the provision of hosting services on the Internet. It is predicted to be the next generation of information technology architecture and offers great potential to enhance productivity and reduce costs. Cloud service providers offer their processing and memory resources to users. By paying for the use of these resources, users can access them for their calculations and processing anytime and anywhere. Cloud computing provides the ability to increase productivity, save information technology resources, and enhance computing power, converting processing power into a tool with constant access capabilities. The use of cloud computing in a system that supports remote education has its own set of characteristics and requires a unique strategy. Students can access a wide variety of instructional engineering materials at any time and from any location, thanks to cloud computing. Additionally, they can share their materials with other community members. The use of cloud computing in e-learning offers several advantages, such as unlimited computing resources, high scalability, and reduced costs associated with e-learning. An improvement in the quality of teaching and learning is achieved through the use of flexible cloud computing, which offers a variety of resources for educators and students. In light of this, the current research presents cloud computing technology as a suitable and superior option for e-learning systems

Design of an E-learning system using semantic information and cloud computing technologies
Humanity is currently suffering from many difficult problems that threaten the life and survival of the human race. It is very easy for all mankind to be affected, directly or indirectly, by these problems. Education is a key solution for most of them. In our thesis we tried to make use of current technologies to enhance and ease the learning process.
We have designed an e-learning system based on semantic information and cloud computing, in addition to many other technologies that contribute to improving the educational process and raising the level of students. The design was built after much research on useful technology, its types, and examples of actual systems that were previously discussed by other researchers.
In addition to the proposed design, an algorithm was implemented to identify topics found in large textual educational resources. It was tested and proved to be efficient against other methods. The algorithm has the ability of extracting the main topics from textual learning resources, linking related resources and generating interactive dynamic knowledge graphs. This algorithm accurately and efficiently accomplishes those tasks even for bigger books. We used Wikipedia Miner, TextRank, and Gensim within our algorithm. Our algorithm‘s accuracy was evaluated against Gensim, largely improving its accuracy.
Augmenting the system design with the implemented algorithm will produce many useful services for improving the learning process such as: identifying main topics of big textual learning resources automatically and connecting them to other well defined concepts from Wikipedia, enriching current learning resources with semantic information from external sources, providing student with browsable dynamic interactive knowledge graphs, and making use of learning groups to encourage students to share their learning experiences and feedback with other learners.Programa de Doctorado en Ingeniería Telemática por la Universidad Carlos III de MadridPresidente: Luis Sánchez Fernández.- Secretario: Luis de la Fuente Valentín.- Vocal: Norberto Fernández Garcí
Technological innovation for digital supply chains within small and medium size manufacturing enterprises
The rapidly growing world of digitalisation opens the doorway for the new era of
automation that plays a crucial role within the industry. Furthermore, technological
innovations that are emerging every day are disrupting traditional business processes
especially within small and medium size manufacturing enterprises (SMEs). The current
industrial revolution pioneer for profit maximisation with cost reduction shows a
significant refinement in improving sustainability that drives forward digitalisation.
Evidence shows that industries have identified digitalisation as a priority in the upcoming
years as the global supply chain is equipping itself with the digital world in the current
industrial revolution. Economic growth is dependent on SMEs around the world where
small and medium size Manufacturing Enterprises (SMMEs) play a vital role in the
current competitive world while they are not able to manage their supply chains
effectively and efficiently due to a lack of optimisation of digitalisation. They identify
that technological innovation is evident for transforming themselves with digital supply
chain, while global market leading organisations are positioning themselves with the
world of digitalisation to their end consumers in their supply chain utilising technological
innovation virtually driving towards a new era of a digital ecosystem.
This research aims to investigate the impact of technological innovation to foster and
promote digital supply chain within SMMEs. Due to the exploratory nature, this study
adopted a case study approach where the data is collected using a semi-structured
interview across 4 cases from three various countries. The findings indicate a lack of
framework for the digitalisation of supply chains within SMMEs, in addition to a lack of
technological innovation and financial constraints that served as limiting factors for
digitalisation of supply chain within organisations. Further, a framework has been
developed consisting of five elements that have been identified from empirical data as
being critical for Digital Supply Chain (DSC) transformation. The theoretical
contributions of this research are the identification of problems faced, limitations of
technological innovation, and an improved understanding of how digital supply chain
transformation can be initiated and achieved in the context of SMMEs. The practical
contribution of this study is imbedded in the developed framework in the form of
recommended strategies for SMMEs for digitalisation of supply chain

Towards the Exploration of Task and Workflow Scheduling Methods and Mechanisms in Cloud Computing Environment
Cloud computing sets a domain and application-specific distributed environment to distribute the services and resources among users. There are numerous heterogeneous VMs available in the environment to handle user requests. The user requests are defined with a specific deadline. The scheduling methods are defined to set up the order of request execution in the cloud environment. The scheduling methods in a cloud environment are divided into two main categories called Task and Workflow Scheduling. This paper, is a study of work performed on task and workflow scheduling. Various feature processing, constraints-restricted, and priority-driven methods are discussed in this research. The paper also discussed various optimization methods to improve scheduling performance and reliability in the cloud environment. Various constraints and performance parameters are discussed in this research
Archaeological 3D GIS
Archaeological 3D GIS provides archaeologists with a guide to explore and understand the
unprecedented opportunities for collecting, visualising, and analysing archaeological
datasets in three dimensions.
With platforms allowing archaeologists to link, query, and analyse in a virtual, georeferenced
space information collected by different specialists, the book highlights how
it is possible to re-think aspects of theory and practice which relate to GIS. It explores
which questions can be addressed in such a new environment and how they are going
to impact the way we interpret the past. By using material from several international
case studies such as Pompeii, Çatalhöyük, as well as prehistoric and protohistoric sites
in Southern Scandinavia, this book discusses the use of the third dimension in support
of archaeological practice.
This book will be essential for researchers and scholars who focus on archaeology and
spatial analysis, and is designed and structured to serve as a textbook for GIS and digital
archaeology courses
