Improving approaches to material inventory management in construction industry in the UK
Materials used in construction constitute a major proportion of the total cost of construction projects. An important factor of great concern that adversely affects construction projects is the location and tracking of materials, which normally come in bulk with minimal identification. There is inadequate integration of modern wireless technologies (such as Radio Frequency Identification (RFID), Personal Digital Assistant (PDA) or Just-in-Time (JIT)) into project management systems for easier and faster materials management and tracking and to overcome human error. This research focuses on improving approaches to material inventory management in the UK construction industry through the formulation of RFID-based materials management tracking process system with projects.
Existing literature review identified many challenges/problems in material inventory management on construction projects, such as supply delays, shortages, price fluctuations, wastage and damage, and insufficient storage space. Six construction projects were selected as exploratory case studies and cross-case analysis was used to investigate approaches to material inventory management practices: problems, implementation of ICT, and the potential for using emerging wireless technologies and systems (such as RFID and PDA) for materials tracking. Findings showed that there were similar problems of storage constraints and logistics with most of the construction projects. The synthesis of good practices required the implementation of RFID-facilitated construction management of materials tracking system to make material handling easier, quicker, more efficient and less paperwork. There was also a recommendation to implement Information and Communication Technology (ICT) tools to integrate plant, labour and materials into one system.
The findings from the cases studies and the literature review were used to formulate a process for real-time material tracking using Radio Frequency Identification (RFID) that can improve material inventory management in the UK construction industry. Testing and validation undertaken assisted in formulating a process that can be useful, functional and acceptable for a possible process systemβs development. Finally, research achievements/contributions to knowledge, and limitations were discussed and some suggestions for further research were outlined

New Container Architectures for Mobile, Drone, and Cloud Computing
Containers are increasingly used across many different types of computing to isolate and control apps while efficiently sharing computing resources. By using lightweight operating system virtualization, they can provide apps with a virtual computing abstraction while imposing minimal hardware requirements and a small footprint. My thesis is that new container architectures can provide additional functionality, better resource utilization, and stronger security for mobile, drone, and cloud computing. To demonstrate this, we introduce three new container architectures that enable new mobile app migration functionality, a new notion of virtual drones and efficient utilization of drone hardware, and stronger security for cloud computing by protecting containers against untrusted operating systems.
First, we introduce Flux to support multi-surface apps, apps that seamlessly run across multiple user devices, through app migration. Flux introduces two key mechanisms to overcome device heterogeneity and residual dependencies associated with app migration to enable app migration. Selective Record/Adaptive Replay to record just those device-agnostic app calls that lead to the generation of app-specific device-dependent state in services and replay them on the target. Checkpoint/Restore in Android (CRIA) to transition an app into a state in which device-specific information the app contains can be safely discarded before checkpointing and restoring the app within a containerized environment on the new device.
Second, we introduce AnDrone, a drone-as-a-service solution that makes drones accessible in the cloud. AnDrone provides a drone virtualization architecture to leverage the fact that computational costs are cheap compared to the operational and energy costs of putting a drone in the air. This enables multiple virtual drones to run simultaneously on the same physical drone at very little additional cost. To enable multiple virtual drones to run in an isolated and secure manner, each virtual drone runs its own containerized operating system instance. AnDrone introduces a new device container architecture, providing virtual drones with secure access to a full range of drone hardware devices, including sensors such as cameras and geofenced flight control.
Finally, we introduce BlackBox, a new container architecture that provides fine-grain protection of application data confidentiality and integrity without the need to trust the operating system. BlackBox introduces a container security monitor, a small trusted computing base that creates separate and independent physical address spaces for each container, such that there is no direct information flow from container to operating system or other container physical address spaces. Containerized apps do not need to be modified, can still make full use of operating system services via system calls, yet their CPU and memory state are isolated and protected from other containers and the operating system

Context-aware software
With the advent of PDAs (Personal Digital Assistants), smart phones, and other forms of mobile and ubiquitous computers, our computing resources are increasingly moving off of our desktops and into our everyday lives. However, the software and user interfaces for these devices are generally very similar to that of their desktop counterparts, despite the radically different and dynamic environments that they face. We propose that to better assist their users, such devices should be able to sense, react to, and utilise, the user's current environment or context. That is, they should become context-aware. In this thesis we investigate context-awareness at three levels: user interfaces, applications, and supporting architectures/frameworks. To promote the use of context-awareness, and to aid its deployment in software, we have developed two supporting frameworks. The first is an application-oriented framework called stick-e notes. Based on an electronic version of the common Post-It Note, stick-e notes enable the attachment of any electronic resource (e.g. a text file, movie, Java program, etc.) to any type of context (e.g. location, temperature, time, etc.). The second framework we devised seeks to provide a more universal support for the capture, manipulation, and representation of context information. We call it the Context Information Service (CIS). It fills a similar role in context-aware software development as GUI libraries do in user interface development. Our applications research explored how context-awareness can be exploited in real environments with real users. In particular, we developed a suite of PDA-based context-aware tools for fieldworkers. These were used extensively by a group of ecologists in Africa to record observations of giraffe and rhinos in a remote Kenyan game reserve. These tools also provided the foundations for our HCI work, in which we developed the concept of the Minimal Attention User Interface (MAUI). The aim of the MAUI is to reduce the attention required by the user in operating a device by carefully selecting input/output modes that are harmonious to their tasks and environment. To evaluate our ideas and applications a field study was conducted in which over forty volunteers used our system for data collection activities over the course of a summer season at the Kenyan game reserve. The PDA-based tools were unanimously preferred to the paper-based alternatives, and the context-aware features were cited as particular reasons for preferring them. In summary, this thesis presents two frameworks to support context-aware software, a set of applications demonstrating how context-awareness can be utilised in the ''real world'', and a set of HCI guidelines and principles that help in creating user interfaces that fit to their context of use
