Numerical tools for the theoretical study of QCD at small x

In this contribution we present the status of two numerical tools designed to study the small x limit of QCD. The first one is a Monte Carlo simulation of the BFKL evolution equation. In design of this approach emphasis has been placed on exploiting the linear behaviour that many variants of the BFKL evolution possess. This allows us to design a procedure which can be used to study theoretical and phenomenological aspects of different kernels. The second one is a semi-analytic approach to study Lipatov's effective action which describes Reggeon interactions. The study of the properties of this action is very complicated and we propose using a computational tool to handle the large amount of non--local vertices and the derivation of higher order corrections.Comment: 7 pages, 3 figures.

Problem-based learning in cybersecurity at CCCU

This work looks at the development of two problem-based learning scenarios. The first of these exercises involved the investigation of social engineering and the second concentrated on the Government’s Cyber Essentials scheme. The problem-based learning was tested over a three-week period, with a two-hour tutor facilitated session every week. For each scenario the students were supplied with a 20-page case study for which they needed to provide their solutions. Students worked in groups of three or four to produce a 20-minute presentation (with speaker notes) by the end of the second week. The third session was used to provide feedback to and evaluation by the students. This presentation will discuss the detail of the scenarios, issues with the running of problem-based learning of this format, the student reactions and evaluations, the quality of the work produced by the students and finally discuss how the PBL approach utilised in teaching cybersecurity can be applied to teaching computer forensics

Ultra-high molecular sink vacuum chamber

Double-wall vacuum chamber can be separated from the remainder of the system and pumped by ultra-clean techniques. Ultrahigh vacuum is maintained by the cryogenic effect of a cold wall and titanium chemisorption

Atmospheric analysis modeling in support of Seasat

Atmospheric objective analysis models were developed and tested in preparation for assessing the utility of Seasat data. Of the several discretionary procedures in such computer programs, the effects of three were examined and documented: (1) the effect of varying the weights in the pattern conserving techniques; (2) the effect of varying the data influence region; (3) the effect of including wind information in analysis of mass-structure variables. The problem of inserting bogus reports is also examined

Diffusion algorithms and data reduction routine for onsite launch predictions for the transport of Titan 3 C exhaust effluents

The NASA/MSFC multilayer diffusion algorithms have been specialized for the prediction of the surface impact for the dispersive transport of the exhaust effluents from the launch of a Titan 3 vehicle. This specialization permits these transport predictions to be made at the launch range in real time so that the effluent monitoring teams can optimize their monitoring grids. Basically, the data reduction routine requires just the meteorology profiles for the thermodynamics and kinematics of the atmosphere as an input. These profiles are graphed along with the resulting exhaust cloud rise history, the center line concentrations and dosages, and the hydrogen chloride isopleths

Wind turbine acoustic standards

A program is being conducted to develop noise standards for wind turbines which minimize annoyance and which can be used to design specifications. The approach consists of presenting wind turbine noise stimuli to test subjects in a laboratory listening chamber. The responses of the subjects are recorded for a range of stimuli which encompass the designs, operating conditions, and ambient noise levels of current and future installations. Results to date have established the threshold of detectability for a range of impulsive stimuli of the type associated with blade/tower wake interactions. The status of the ongoing psychoacoustic tests, the subjective data, and the approach to the development of acoustic criteria/standards are described

Open source Internet research tool

Open source research on the Internet has become an everyday requirement for law enforcement officials. The special requirements of such activity include keeping a useable audit trail, screen capture of static and dynamic content, and document capture. All of these artefacts need to be stored in an evidential container and captured content should be suitably hashed. A report must then be generated from the evidence gathered. At the moment police in the UK use a number of different tools to carry out this process but there is no one tool that meets all of the requirements in an integrated way. This research seeks to fill this gap by creating a bespoke tool in collaboration with the College of Policing that allows one tool to carry out all tasks required for law enforcement to carry out open source internet research as part of a single tool and an integrated process. Written in C#, this early iteration of the tool automatically logs all websites visited, hashes all screenshots and downloaded files using MD5 for validation, and generates reports in PDF format detailing all activities within the case; allowing for dissemination to other departments/individuals. Presently, there are no overall guidelines within the UK of which we are aware for how Internet evidence should be gathered. For example, when a website makes an external call to download a JavaScript file, or access the Facebook API, should that be documented within the audit log? How should a tool of this nature deal with dynamic content, such as AJAX? Future plans for this project include a browser ‘hot-swap’ facility, addition of the ability to screen record browser activity, and to make the tool suitable for international use on multiple-platforms
