It was hypothesised that the improvements in Windows 8 and new features of Windows 8 may cause new challenges to Digital Forensic investigation. Similarly, the forensic techniques that worked perfectly on the past version of Windows might require changes when dealing with a Windows 8 machine. The objective of the research was hence to find out the investigation challenges of the new features in Windows 8 that could impact on the Digital Forensic investigation process. The research focuses on the Digital Forensic investigation process gap when dealing with the new version of the operating system. The research first started by reviewing the past Windows platforms with a focus on comparing Windows 7 and Windows 8 to identify the differences. Digital Forensic areas such as Digital Forensic tools and existing Digital Forensic model were also explored. The problem areas related to Digital Forensic techniques, Windows 8 Digital Forensic issues, and Windows 8 features issues were identified. The reviews were narrowed down to review the gap in research in one area. Then the main research question and sub questions for the research were constructed. The main questions chosen for the research was “What new features in Windows 8 Operating System pose new challenges to the Digital Forensic investigation?” The hypotheses of the research were also defined for testing before the methodology was introduced in order to conduct the experiments to answer the research question and also test the hypothesis. The research phases followed the six phases “Preparation, Incident Response, Data Collection, Data Analysis, the Report and Incident Closure”. Each of the phases was recorded and the results of the findings were used to assist in answering the research questions. Based on the findings, the three new features in Windows 8 of significance were the secure boot, after reset option and communication applications. These features, in Windows 8 were found to bring new challenges for Digital Forensic investigations. iv Table of Contents Formalities Declaration ........................................................................................................... i Acknowledgements ............................................................................................. ii Abstract .............................................................................................................. iii Table of Contents ............................................................................................... iv List of Tables ...................................................................................................... x List of Figures ................................................................................................... xii Chapter 1 – Introduction 1.0 INTRODUCTION .................................................................................... 1 1.1 PROBLEM AREAS ................................................................................. 2 1.2 MOTIVATION ........................................................................................ 3 1.3 STRUCTURE OF THE THESIS .............................................................. 5 Chapter 2 – Literature Review 2.0 INTRODUCTION .................................................................................... 8 2.1 REVIEW OF WINDOWS 7 RESEARCH ................................................ 9 2.1.1.

  • The AGN Ionization Cones of NGC 5728: I-Excitation and Nuclear Structure
    Typeset using LATEX twocolumn style in AASTeX62 Draft version October 9, 2018 The AGN Ionization Cones of NGC 5728 : I - Excitation and Nuclear Structure Mark Durre´1 and Jeremy Mould1 1Centre for Astrophysics and Supercomputing, Swinburne University of Technology, P.O. Box 218, Hawthorn, Victoria 3122, Australia ABSTRACT We explore the gas morphology and excitation mechanisms of the ionization cones of the Type II Seyfert galaxy NGC 5728. Near-IR and optical data from the SINFONI and MUSE IFUs on the VLT are combined with HST optical images, Chandra X-ray data and VLA radio observations. The complex nuclear structure has a star-forming (SF) ring with a diameter of 2 kpc. A radio jet impacts on the ISM at about 200 pc from the nucleus, with the SN remnants in the SF ring also present. Emission-line ratios of [Fe II] and H II show heavy extinction towards the nucleus, moderate extinction in the SF ring and reduced extinction in the ionization cones. The AGN is hidden by a dust bar with up to 19 magnitudes of visual extinction; the dust temperature at the nuclear position is ∼ 870 K. An X-ray jet is aligned with the ionization cones, and associated with high-excitation emission lines of [Si VI] in a coronal-line region extending 300 pc from the nucleus. Molecular hydrogen is spatially independent of the cones, concentrated in a disk equatorial to the star-forming ring, but also showing entrainment along the sides of the bicone. Gas masses for warm and cold H2,H I and H II are estimated, and the excitation mechanisms for ionized and molecular gas are elucidated, from both optical (which shows a clean SF-AGN mixing sequence) and infrared diagnostics (which show more complicated, multi-component excitation regimes).

  • Who's Afraid of 3D Printing?
    THIS VERSION MAY CONTAIN INACCURATE OR INCOMPLETE PAGE NUMBERS. PLEASE CONSULT THE PRINT OR ONLINE DATABASE VERSIONS FOR THE PROPER CITATION INFORMATION. ARTICLE WHO'S AFRAID OF 3D PRINTING? BEN DEPOORTER* & BREGT RAUS† ABSTRACT Heralded for ushering in a new era of personalized manufacturing, there is a growing fear that consumer 3D printing is the next frontier of massive intellec- tual property infringements. Described as the Napster of patents, illegal 3D printing is foretold to disrupt manufacturing in the same manner as digital piracy unsettled the music industry. This Article shows that the negative forecast of rampant 3D printing piracy is overstated. We explain how the purported analogies between P2P file sharing and consumer 3D printing overlook essential differences between piracy of me- dia content and physical property. We caution against aggressive enforcement against unauthorized consumer 3D printing that would impede innovation and the development of 3D printing technologies. *Max Radin Distinguished Professor - University of California, Hastings Law School; Visit- ing Professor, U.C.

  • A Cross-Platform Programmer's Calculator
    – Independent Work Report Fall, 2015 – A Cross-Platform Programmer’s Calculator Brian Rosenfeld Advisor: Robert Dondero Abstract This paper details the development of the first cross-platform programmer’s calculator. As users of programmer’s calculators, we wanted to address limitations of existing, platform-specific options in order to make a new, better calculator for us and others. And rather than develop for only one- platform, we wanted to make an application that could run on multiple ones, maximizing its reach and utility. From the start, we emphasized software-engineering and human-computer-interaction best practices, prioritizing portability, robustness, and usability. In this paper, we explain the decision to build a Google Chrome Application and illustrate how using the developer-preview Chrome Apps for Mobile Toolchain enabled us to build an application that could also run as native iOS and Android applications [18]. We discuss how we achieved support of signed and unsigned 8, 16, 32, and 64-bit integral types in JavaScript, a language with only one numerical type [15], and we demonstrate how we adapted the user interface for different devices. Lastly, we describe our usability testing and explain how we addressed learnability concerns in a second version. The end result is a user-friendly and versatile calculator that offers value to programmers, students, and educators alike. 1. Introduction This project originated from a conversation with Dr. Dondero in which I expressed an interest in software engineering, and he mentioned a need for a good programmer’s calculator. Dr. Dondero uses a programmer’s calculator while teaching Introduction to Programming Systems at Princeton (COS 217), and he had found that the pre-installed Mac OS X calculator did not handle all of his use cases.
