In recent decades, Internet auctions have already been grown up as the most significant e-commerce business model in worldwide. Meanwhile, with the rapid rising of cloud computing over the past few years, the legacy online auction platform is gradually replaced by service-oriented cloud computing in real time. This thesis describes design and implementation of a high-performance online auction system over the cloud. We propose the methodology to provide persistent state records during the auction process so that we can ensure the reliability of submitted bid price, fairness and guarantee the security of price message in the delivery process. We employ the actor-based applications to achieve stateful, parallel and distributed architecture. Moreover, utilising distributed databases to provide secure and efficient data storage. Our preliminary result provides the guidelines for implementation of high-performance and real-time bidding online auction. Auction fraud has become the highest threat and hazard to the future of this business model (Grazioli & Jarvenpaa, 2000). In this thesis, we are going to demonstrate the details of blockchain which will provide a new perspective to resolve this problem. It is able to be used for current financial services, certificates, remittances and online payments. Furthermore, it also provides several crucial services such as smart contract, smart property, trust system and security services (Gareth William Peters, Panayi, & Chapelle, 2015). This thesis will discuss how to apply a private blockchain to a cloud- based online auction and the principle of operation. The purpose is to fundamentally solve the problem of online fraud caused by information asymmetry of electronic transactions. To the best of our knowledge, this is the first time that the blockchain is applied to authentication of online auction. Our preliminary result is for preventing auction fraud from the aspects of smart properties and smart contract.

The paper aims to propose a distributed clustering method for High performance computing (HPC) models and, its application for medical image processing. The communication cost is one of the great challenges, which minimizes the scalability of parallel and distributed computing models. Indeed, it reduces significantly the performance of HPC systems where these models are assigned to be implemented. In this paper, we present a new distributed k-means method which integrates virtual paralleldistributed computing model with a low communication cost mechanism. The k-means method is performed as a distributed service within a cooperative micro-services team which uses asynchronous communication mechanism based on AMQP protocol. We design and implement a parallel and distributed HPC application for MRI image segmentation assigned to be deployed on cloud. Experimental results show that the proposed method (DSCM) and its assigned model reach high degree of scalability. We expect this clustering approach to provide scalable HPC applications for big data clustering.

The Kohonen self-organizing map (SOM) is an important tool to find a mapping from high-dimensional space to low dimensional space. The time a SOM requires increases with the number of neurons. A parallel implementation of the algorithm can make it faster. This paper investigates the most recent parallel algorithms on SOMs. Using Java network programming utilities, improved parallel and distributed system are set up to simulate these algorithms. From the simulations, we conclude that those algorithms form good feature maps.

In the previous years, the use of Internet and other internet based technology were increased impulsively. The cloud of Things is (CoT) a smart technology which permits the access of services or anything over the internet at any time and can be used anywhere. CoT is a joined technology of Cloud Computing and Internet of Things (IoT). IoT turning out to be pervasive to the point that it is getting to be distinctly essential to incorporate with the cloud environment. Due to the measure of information IoT's could produce and their prerequisite to have the benefit of essential assets usage and capacity limits. Additionally, making it conceivable to make extra value from the information created by IoT's and create useful and smart applications for the clients. Due to the ubiquitous nature of CoT, it is continuously draining energy from resources. So, energy efficient CoT has arisen as a major research problem. In this manuscript, energy effcient design for CoT has been discussed.
