title: Behaviour based ransomware detection

authors: Chew, Christopher J.W.

subjects: computer science

abstract: Ransomware is an ever-increasing threat in the world of cyber security targeting vulnerable users and companies, but what is lacking is an easier way to group, and devise practical and easy solutions which every day users can utilise.
In this paper we look at the different characteristics of ransomware, and present preventative techniques to tackle these ransomware attacks. More specifically our techniques are based on ransomware behaviour as opposed to the signature based detection used by most anti-malware software. We further discuss the implementation of these techniques and their effectiveness. We have tested the techniques on four prominent ransomware strains, WannaCry, TeslaCrypt, Cerber and Petya. In this paper we discuss how our techniques dealt with these ransomware strains and the performance impact of these techniques.

title: Optimisation of performance of dispersants in aqueous titanium slips

authors: Xu, Qian

subjects: Dispersants

abstract: Slip casting is a well-established ceramic casting technique used for large scale fabrication of ceramic products with complex shapes. A homogenous slip with a desired level of stability is required, which is controlled using a dispersant. This paper describes the selection and optimisation of various dispersants used to produce Ti powder slips. A consideration of the effect of concentration and pH of the solvent on the dispersion of anionic polyelectrolyte dispersants (Dispex N-40, Synthecol SD375 & Dolapix CE64) was examined by measuring the sedimentation height and rate, the streaming potential and the slip viscosity. It was found that Dolapix CE64 showed the best deflocculating effect at 0.3dw.% with pH of 7. In particular, the measurements on Dolapix CE64 gave consistent results. This indicated that Dolapix CE64 is an effective dispersant in the preparation of a titanium slip.

title: Te Tarata

authors: Maxwell, Te Kahautu

abstract: This composition placed second in the Haka Composition Section. Te Tarata this composition commemorates the battle of Te Tarata in Te Whakatōhea 15 October 1865. This was the aftermath of the killing of the missionary Rev Carl Sylvius Volkner on the 2 March 1865. At the battle of Te Tarata it is recorded as the only calvary charge in the New Zealand Land Wars. Te Whakatōhea ingeniously wove around the palisade walls tī kouka (Cordyline australis) or cabbage tree. When the canon ball hit the palisades the tī kouka absorbed the force of the canon ball and rebounded the ball. 20 Te Whakatohea were killed and a number of others were wounded. This composition was performed by Ōpōtiki Mai Tawhiti at the Te Matatini World Championship Kapa Haka Competition 2015.
