Man-in-the-Middle Attack Test-bed Investigating Cyber-security Vulnerabilities in Smart Grid SCADA Systems

The increased complexity and interconnectivity of Supervisory Control and Data Acquisition (SCADA) systems in the Smart Grid has exposed them to a wide range of cyber-security issues, and there are a multitude of potential access points for cyber attackers. This paper presents a SCADA-specific cyber-security test-bed which contains SCADA software and communication infrastructure. This test-bed is used to investigate an Address Resolution Protocol (ARP) spoofing based man-in-the-middle attack. Finally, the paper proposes a future work plan which focuses on applying intrusion detection and prevention technology to address cyber-security issues in SCADA systems.

Towards Understanding Man-In-The-Middle Attacks on IEC 60870-5-104 SCADA Networks

This paper investigates cyber attacks on ICS which rely on IEC 60870-5-104 for telecontrol communications. The main focus of the paper is on man-in-the-middle attacks, covering modification and injection of commands, it also details capture and replay attacks. An initial set of attacks are preformed on a local software simulated laboratory. Final experiments and validation of a man-in-the-middle attack are performed in a comprehensive testbed environment in conjunction with an electricity distribution operator.

Man-up Against Suicide

Male suicide rates are high in Western countries including the US and Canada. Underpinned by men’s resistance to health help-seeking and challenges diagnosing mental illness including male depression, suicide ends the lives of many men amid inflicting pain and grief on the family and friends who are left behind. Fuelled by the discordant relationship between men’s low rates of depression and high rates of suicide we embarked on a unique and novel photovoice study title Man-Up Against Suicide. Specifically, men who have contemplated suicide in the past, and individuals (men and women) who have lost a male partner, family member or friend to suicide were invited to take photographs representing their experiences with men’s suicide with the ultimate goal of messaging ‘at risk’ men that there are alternatives to taking one’s life. Participants subsequently completed semi-structured individual interviews narrating the photographs and providing captions to accompany their selected images. In this presentation we share the preliminary study findings along with some participant photographs and narratives as a means to discussing; 1) men’s experiences of suicidal behaviours and their management strategies; and, 2) how men’s and women’s experiences of losing a male to suicide can de-stigmatize men’s mental illness and raise public awareness about male suicide.

Essays on James Clarence Mangan: The Man in the Cloak

This volume explores the extraordinary literary achievement of James Clarence Mangan (1803-1849), increasingly recognised as one of the most important Irish writers of the nineteenth century and a crucial influence on later writers such as W.B. Yeats and James Joyce. It is the first collection of essays to focus on Mangan, and features articles by leading scholars in the field (including Jacques Chuto and David Lloyd) as well as contributions from acclaimed contemporary writers, Paul Muldoon and Ciaran Carson. The collection expands existing fields of debate--translation, the supernatural, intertextuality, nationalism, romanticism-- and introduces new ones: Mangan's afterlife in the English literary canon, cosmopolitanism and Weltliteratur, antiquity and futurity, nineteenth-century spiritualism and magical thinking. 'The man in the cloak', one of Mangan's favourite pseudonyms, is still a a resonant soubriquet for a writer who has eluded sustained critical attention, and this volumes restores him to his proper place in European and British, as well as Irish literary history.

The androgen receptor induces a distinct transcriptional program in castration-resistant prostate cancer in man

The androgen receptor (AR) regulates prostate cell growth in man, and prostate cancer is the commonest cancer in men in the UK. We present a comprehensive analysis of AR binding sites in human prostate cancer tissues, including castrate-resistant prostate cancer (CRPC). We identified thousands of AR binding sites in CRPC tissue, most of which were not identified in PC cell lines. Many adjacent genes showed AR regulation in xenografts but not in cultured LNCaPs, demonstrating an in-vivo-restricted set of AR-regulated genes. Functional studies support a model of altered signaling in vivo that directs AR binding. We identified a 16 gene signature that outperformed a larger in-vitro-derived signature in clinical data sets, showing the importance of persistent AR signaling in CRPC.

Joseph Priestley: the man who drew time

The Joseph Priestley House Museum at Northumberland, Pennsylvania became interested in Priestley's pioneering timelines as a complement to his better known work in chemistry, electricity, biblical scholarship and political radicalism. Boyd Davis wrote this short article for the newsletter published by the Friends of the museum. The article concentrates on the connections between Priestley, his French contemporary Barbeu-Dubourg and Benjamin Franklin at the time of the struggle for American Independence, and Priestley's two key chronographic innovations: the use of drawn or printed lines to represent the duration of lives, and the associated use of dots to show when the dates of such lives are in doubt or dispute. Keywords: timeline, chronographics

Local gist vision of man-made objects

Attention is usually modelled by sequential fixation of peaks in saliency maps. Those maps code local conspicuity: complexity, colour and texture. Such features have no relation to entire objects, unless also disparity and optical flow are considered, which often segregate entire objects from their background. Recently we developed a model of local gist vision: which types of objects are about where in a scene. This model addresses man-made objects which are dominated by a small shape repertoire: squares, rectangles, trapeziums, triangles, circles and ellipses. Only exploiting local colour contrast, the model can detect these shapes by a small hierarchy of cell layers devoted to low- and mid-level geometry. The model has been tested successfully on video sequences containing traffic signs and other scenes, and partial occlusions were not problematic.

Arbeits- und Lerntechniken - wie man sich perfekt organisiert

In der Schule unterrichtet man Einzelfächer wie Mathematik, Deutsch, Englisch, Physik, Kunst. Kein Fachlehrer fühlt sich für das übergreifende Thema "Lernen" zuständig. Die Naturtalente unter den Schülern können es eh - das Lernen. Die anderen wursteln sich durch, mit mehr Anstrengung als nötig wäre - oder sie scheitern. Für das Studium genügt Wursteln nicht, man braucht effiziente Arbeits- und Lerntechniken. Diese Ausarbeitung hilft bei der Selbstorganisation des Studiums.
