This paper presents a holistic methodology for the design of medical device software, which encompasses of a new way of eliciting requirements, system design process, security design guideline, cloud architecture design, combinatorial testing process and agile project management. The paper uses point of care diagnostics as a case study where the software and hardware must be robust, reliable to provide accurate diagnosis of diseases. As software and software intensive systems are becoming increasingly complex, the impact of failures can lead to significant property damage, or damage to the environment. Within the medical diagnostic device software domain such failures can result in misdiagnosis leading to clinical complications and in some cases death. Software faults can arise due to the interaction among the software, the hardware, third party software and the operating environment. Unanticipated environmental changes and latent coding errors lead to operation faults despite of the fact that usually a significant effort has been expended in the design, verification and validation of the software system. It is becoming increasingly more apparent that one needs to adopt different approaches, which will guarantee that a complex software system meets all safety, security, and reliability requirements, in addition to complying with standards such as IEC 62304. There are many initiatives taken to develop safety and security critical systems, at different development phases and in different contexts, ranging from infrastructure design to device design. Different approaches are implemented to design error free software for safety critical systems. By adopting the strategies and processes presented in this paper one can overcome the challenges in developing error free software for medical devices (or safety critical systems).

The sequential computation of hashes at the core of many distributed storage systems and found, for example, in grid services can hinder efficiency in service quality and even pose security challenges that can only be addressed by the use of parallel hash tree modes. The main contributions of this paper are, first, the identification of several efficiency and security challenges posed by the use of sequential hash computation based on the Merkle-Damgard engine. In addition, alternatives for the parallel computation of hash trees are discussed, and a prototype for a new parallel implementation of the Keccak function, the SHA-3 winner, is introduced.

We propose a solution to avoid stability, security and performance concerns in multi-player games. This should lead to greater scalability in existing multi-player games but could also provide a way to implement multi-player functionality in an existing single-player game whilst ensuring the code-base stays organised and robust without requiring large modifications to the existing architecture. The ideas presented in this publication aim to provide a scalable solution not just to the end product but also to the code base in order to ensure greater ease in future maintainability and expansion.

With massive penetration of mobile phones the tourism industry is adopting augmented technology (AR) and apps supported by smartphones to create and provide a memorable and exciting experience to tourists with fun, interaction and learning. In this paper we first introduce the basic AR technology and then review several typical and well-known AR engines/platforms developed by companies and research institutes, focusing on their technical aspects. The challenges and recent development trends and directions are analysed to provide an insight for future research and development of AR technology for tourism and beyond.

design of a web-based thesaurus for Systems of Systems engineering (SoSE) discipline is presented in this article. Due to lack of linguistic clarity within this emerging discipline, there is a strong need to represent and interpret SoS concepts and terms to align heterogeneous models, and tools and techniques developed for SoS operations, management and its governance. A Blackboard-based systems approach is therefore used to devise a model, providing a mechanism for high level organisation and sharing of knowledge and information within the SoSE thesaurus system. To illustrate its applicability, a scenario derived from realistic use cases is provided. The potential benefits of this research are identified and a brief description of intended further work is given.
