Configuration files are a vital part of any server setup. Knowing what configuration files have been manipulated is vital in knowing what services are running and how they are configured on a system. Changes made to these configuration files must be manually documented or collected using some automated documentation tool. Both these methods rely on being implemented early for the changes to be sufficiently documented. If a system didn’t implement these methods of documentation then there is no absolute way of knowing what changes have been made to that system without doing a manual search through potentially hundreds of files to find changes. Finding all changes made to a system lacking documentation is a time-consuming and arduous task. What if the search for changes could be automated once the documentation is long overdue? This thesis aims to create an implementation that finds changes made to configuration files on a Debian system as well as Linux distributions based on Debian such as Ubuntu. The resulting implementation created is called Doc-Overdue. Doc-Overdue consists of a script written in Python and utilizes the Debian Package Management System to find reference files to compare to the configuration files on the system. The script also runs tests to aid in finding new and/or modified configuration files without a reference file available. The results are presented in a formatted comprehensive report automatically created by Doc-Overdue. The report will include change reports created by the Diff-utility that makes it easy to find exactly what changes have been made to each changed configuration file. This approach finds changes made to systems without the need for any prior documentation of the system. The implementation was tested with a custom-made script that made modifications to configuration files for Doc-Overdue to find. The test showed Doc-Overdue to have an accuracy of 87.5% in finding changed configuration files on the system. This result shows that this approach for finding configuration file changes has a lot of promise. The thesis ends with a discussion and a list of potential future work that could hopefully lead to further improvements in the field of configuration detection.

No / Past research on care leavers has, understandably, tended to focus on those who are in their mid- to late-teens or early 20s. This reflects the profound impact of central and local government policy on those young people. It also reflects their prominence in contemporary analyses of most of the indicators of social exclusion among young people in the UK - unemployment, homelessness and lack of educational qualifications among them. However, some issues affecting adults who grew up in care apply across the life course. One such issue is the access that former care adults have to their child care files. Indeed, as we shall see, this issue has particular importance for many older adults (in their 30s and upwards). Policy and practice in this field has changed significantly during the past 20¿years and there is a growing awareness of the needs of former care adults in this area. Access to such files can be a significant element in the process of seeking to address identity concerns centring around family and childhood experiences. This paper explores some of these identity concerns and analyses how access to care files both reflects such concerns and attempts to address them.

The present thesis examines questionnaire responses regarding optimal environmental attributes of public outdoor spaces for Chinese grandparents who are taking care of their grandchildren within selected urban residential communities in Shanghai, China. This thesis also assesses the needs of these grandparents providing childcare against the environmental attributes of urban public spaces. It uses the results to formulate design recommendations that will facilitate increased social interaction between grandparents with grandchildren and other persons in open public spaces of residential communities. Public spaces are often excellent locations for social interaction between grandparents with other persons within communities. Recently, there has been an increase in the number of Chinese grandparents providing childcare for their grandchildren, and many choose to spend time with grandchildren in these public open spaces. However, the needs and preferences of this demographic do not necessarily align with those of the general population. The current literature has identified five primary environmental attributes (access, comfort, opportunities of meeting, potential sensory elements, visibility) related to social interaction, each composed of a variety of landscape elements and characteristics. A framework was constructed based on these five environmental attributes and a variety of landscape elements and characteristics, and used to formulate a questionnaire for 46 grandparents, who take care of their grandchildren and live in high-rise buildings were surveyed. The selected participants were witnessed watching over their grandchildren in open spaces or the accompanying facilities and were asked to express a level of preference for a series of landscape elements presented in a questionnaire. The survey also included questions regarding demographic information. Descriptive and inferential analysis were then carried out through the survey data. The intended result of the study involved establishing a set of landscape architectural design recommendations that could be used in order to meet the preferences of this portion of society. Ideally, the findings will assist those involved in designing and managing outdoor environments in identifying the most salient environmental attributes for this growing sector of the Chinese community. The study could also help to prioritize interventions aimed at improving the use of open spaces and promoting social interaction among grandparents or grandparents with other neighbors. The approach also identified which landscape elements were most likely to attract grandparents to visit and stay in neighborhoods' open spaces longer with their grandchildren. Ideally, an outdoor public space designed following this set of design recommendations would contain the preferred environmental attributes and landscape elements of grandparents and their grandchildren and would provide more opportunities for social interaction. / Master of Landscape Architecture

<p dir="ltr">The presence of digital devices in various settings, from workplaces to personal spaces, necessitates reliable and secure data storage solutions. These devices store data on non-volatile media like Solid State Drives (SSDs) and Hard Disk Drives (HDDs), ensuring data preservation even after power loss. Files, fundamental units of data storage, are created, modified, and deleted through user activities like application installations or file management. File systems, acting as the backbone of the system, manage these files on storage devices.</p><p dir="ltr">This research explores how three key factors: (1) different operating systems running various file system types (ext4, NTFS, FAT, etc.), (2) different disk types (SSD and HDD), and (3) common user activities (system shutdowns, reboots, web browsing, downloads, etc.) influence the persistence of deleted files.</p><p dir="ltr">This research aims to fill a gap in the understanding by looking at how these factors influence how quickly new information overwrites deleted files. This is especially important for digital forensics, where investigators need to be sure they can find all the evidence on a device. The research will focus on how operating systems handle deleted files and how everyday activities affect the chances of getting them back. This can ultimately improve data security and make digital forensics more reliable.</p>

No / A literature review of published case studies reporting progress file implementation was conducted with the intent of discovering how this is being interpreted and implemented in higher education institutions. The three studies found were analysed using an ideal type categorization developed by Clegg and Bradley (2006), that is, professional, academic or employment. All three case studies are examples of academics learning through experience about the process of personal development planning and how this integrates with current educational provision. As this is not a static process, an activity theory perspective may be a more useful framework to research how this understanding develops in a particular context. Currently the progress file is a contested object, which has not yet fulfilled its potential to place the student and their individual learning needs at the centre of the educational process.

This document focuses on background and performance practice of various musical styles encountered in Paquito D'Rivera's The Cape Cod Files. More specifically, the musical styles examined include: boogie-woogie, Argentine milonga, classical and popular Cuban music, American twelve-bar blues, contemporary atonal music, and Cuban danzón. A brief biography of Paquito D'Rivera is included to establish context of the composer's musical background. Each chapter examines one of the four movements and the musical styles found within that movement. A brief history of each musical style is provided to inform appropriate performance practice decisions.

Les files d'attente fluides sont des processus markoviens à deux dimensions, où la première composante, appelée le niveau, représente le contenu d'un réservoir et prend des valeurs continues, et la deuxième composante, appelée la phase, est l'état d'un processus markovien dont l'évolution contrôle celle du niveau. Le niveau de la file fluide varie linéairement avec un taux qui dépend de la phase et qui peut prendre n'importe quelle valeur réelle. Dans cette thèse, nous explorons le lien entre les files fluides et les processus QBD, et nous appliquons des arguments utilisés en théorie des processus de renouvellement pour obtenir la distribution stationnaire de plusieurs modèles fluides. Nous commençons par l'étude d'une file fluide avec un réservoir de taille infinie; nous déterminons sa distribution stationnaire, et nous présentons un algorithme permettant de calculer cette distribution de manière très efficace. Nous observons que la distribution stationnaire de la file fluide de capacité infinie est très semblable à celle d'un processus QBD avec une infinité de niveaux. Nous poursuivons la recherche des similarités entre les files fluides et les processus QBD, et nous étudions ensuite la distribution stationnaire d'une file fluide de capacité finie. Nous montrons que l'algorithme valable pour le cas du réservoir infini permet de calculer toutes les quantités importantes du modèle avec un réservoir fini. Nous considérons ensuite des modèles fluides plus complexes, de capacité finie ou infinie, où le comportement du processus markovien des phases peut changer lorsque le niveau du réservoir atteint certaines valeurs seuils. Nous montrons que les méthodes développées pour des modèles classiques s'étendent de manière naturelle à ces modèles plus complexes. Pour terminer, nous étudions les conditions nécessaires et suffisantes qui mènent à l'indépendance du niveau et de la phase d'une file fluide de capacité infinie en régime stationnaire. Ces résultats s'appuient sur des résultats semblables concernant des processus QBD. Markov modulated fluid queues are two-dimensional Markov processes, of which the first component, called the level, represents the content of a buffer or reservoir and takes real values; the second component, called the phase, is the state of a Markov process which controls the evolution of the level in the following manner: the level varies linearly at a rate which depends on the phase and which can take any real value. In this thesis, we explore the link between fluid queues and Quasi Birth-and-Death (QBD) processes, and we apply Markov renewal techniques in order to derive the stationary distribution of various fluid models. To begin with, we study a fluid queue with an infinite capacity buffer; we determine its stationary distribution and we present an algorithm which performs very efficiently in the determination of this distribution. We observe that the equilibrium distribution of the fluid queue is very similar to that of a QBD process with infinitely many levels. We further exploit the similarity between the two processes, and we determine the stationary distribution of a finite capacity fluid queue. We show that the algorithm available in the infinite case allows for the computation of all the important quantities entering in the expression of this distribution. We then consider more complex models, of either finite or infinite capacities, in which the behaviour ff the phase process may change whenever the buffer is empty or full, or when it reaches certain thresholds. We show that the techniques that we develop for the simpler models can be extended quite naturally in this context. Finally, we study the necessary and sufficient conditions that lead to the independence between the level and the phase of an infinite capacity fluid queue in the stationary regime. These results are based on similar developments for QBD processes.
