Performance evaluation of IPV6 routing on RC systems
No full textResearch in reconfigurable computing is becoming more pronounced with the increasing research effort being invested in this area. By placing the computationally intense portions of an application onto the reconfigurable hardware, that application can be greatly accelerated. Reconfigurable computers offer a compromise between the performance advantages of fixed-functionality hardware and the flexibility of software-programmable substrates. This paper presents a mapping of router as well as host routing algorithms pertaining to the IPv6 protocol on the MorphoSys, a reconfigurable system that has 64 processing cells potentially operating in parallel. Results proved that Morphosys achieves higher performance by 2 to 4-fold than some available routers.BAGHERZADEH N, 2000, J VLSI SIGNAL PROCES; Barat F, 2000, P IEEE RAP SYST PROT, P168, DOI 10.1109-IWRSP.2000.855217; *CISC SYST INC, 2001, DATA SHEET; Compton K, 2002, ACM COMPUT SURV, V34, P171, DOI 10.1145-508352.508353; Diab H, 2003, ACS IEEE INT C COMP; GULATI S, 2000, ACM CROSSROADS S AUG; *INT CORP, 2001, DAT SHEET; Thomas S.

Modeling squeeze films in the vicinity of high inertia oscillating microstructures
No full textThis work investigates the effect of various assumptions proposed by the classical Reynolds lubrication equation. In particular, a microplate oscillating at high frequencies (beyond cutoff) and high velocities leading to appreciable displacement within the film gap is studied. An analytical model is derived with special emphasis on the fluid's inertia effect on the fluid-solid interface. By implementing the direct simulation Monte Carlo (DSMC) method, a numerical method for modeling rarefied gas flow, the analytically based model is adjusted for the force exerted by the gas on the oscillating micro-structure to capture various significant effects related to the fluid's inertia, compressibility, stiffness, and damping.

I, Penguin
No full text'I, Penguin' is a performance by Susan Diab as an animated reading of a script written after time was spent 'conversing' with a taxidermy penguin of the species 'Little Blue'. Alluding to post-humanist, New Materialist theories and drawing on the 'vegan poetics' of Anat Pick, the performance shows its audience insights gleaned by the author into what it means to look at an object in a museum which was once a living creature. ( Susan Diab)On the 16th November 2017, the Booth Museum hosted a sell-out late event ‘Uncovering the Muse’, as part of its MUPI relationship with the University of Brighton. This event brought together academics from across the university, whose brief was to investigate the Booth collection and develop a talk or workshop aimed at the public. Our wonderful presenters were:Dr Marcus Winter (Computer Science), Ross Adamson/Digital Storytelling Collective (Media), Susan Diab (Critical Fine Art Practice) and Dr Rachel White (Biology).(From event report by Craig Jordan-Baker)<br/
Mapping and Performance Analysis of Lookup Table Implementations on Reconfigurable Platform
No full textReconfigurable computing has a recognized potential in processor design. It provides a middle trade-off between speed and flexibility. It provides performance close to application-specific-hardware, yet preserves the general-purpose-processor flexibility. This paper presents the mapping and performance analysis of the implementation of the lookup table for two encryption algorithms, namely Rijndael and Twofish, on a coarse grain dynamic reconfigurable platform, namely MorphoSys. MorphoSys is a dynamic reconfigurable architecture targeted for computer intensive applications with parallel nature. Since the MorphoSys does not support the indirect addressing, we present in this paper a methodology to implement an alternative. We present the details of the mapping of the two lookup tables with thorough analysis. The methodology we used can be utilized in other Memoryless systems. Finally, an instruction set extension was proposed to enhance the performance. © 2007 IEEE.Almaini AEA, 1994, ELECT LOGIC SYSTEMS; BAGHERZADEH N, 2000, J VLSI SIGNAL PROCES; DAEMEN J, 2002, AES ADV ENCRYPTION S; DIAB H, 2003, ACSIEEE INT C COMP S; Green D.H., 1986, MODERN LOGIC DESIGN; Hartenstein R, 2001, DESIGN AUTOMATION TE; HARTENSTEIN R, 2001, P C AS S PAC DES AUT; HAUCK S, 1998, FUTURE RECONFIGURABL; *IST, ARCH METH DYN REC LO; MAJZOUB S, 2003, ACSIEEE INT C COMP S; Schneier B., 1996, APPL CRYPTOGRAPHY PR; Schneier B., 1998, TWOFISH 128 BIT BLOC; Singh H, 2000, IEEE T COMPUT, V49, P465, DOI 10.1109-12.859540; TESSIER R, 2002, RECONFIGURABLE COMPU10
R v Khawaja and the fraught question of rehabilitation in terrorism sentencing
No full textIn R v Khawaja, Supreme Court of Canada addressed the question of how courts should handle the sentencing of terrorism offenders. Although it affirmed the Ontario Court of Appeal’s decision to raise the sentence imposed by the trial judge, the Supreme Court took a different approach to the importance of rehabilitation as a goal in terrorism sentencing generally. The Court of Appeal found that because of terrorism’s unique and serious nature, there should be very little consideration of the possibility of rehabilitation. The Supreme Court disagreed, ruling that the weight to be placed on rehabilitation in such cases should be left to trial judges and that, depending on the facts, rehabilitation could be a significant factor even in the context of very serious terror offences.
The author reviews the history of R v Khawaja, contrasting the Supreme Court’s decision with the approach of the Ontario Court of Appeal both in Khawaja and in a number of other cases. He reviews the British and Australian jurisprudence drawn on by the Court of Appeal, which looks on terrorism as a distinct type of crime that calls only for an emphasis on deterrence and punishment in sentencing, and argues that the Supreme Court’s decision indicates a significantly different attitude to the issue. Khawaja allows for rehabilitation to potentially factor into the sentencing of terrorism offenders. The author further considers this decision though the lens Antony Duff’s theory of punishment, which suggests that the concepts of moral agency, equality and the possibility of individual redemption are foundational to a sense of political community. He argues that the Supreme Court’s decision constitutes an implicit affirmation of Duff’s view on the importance of the goal of rehabilitation even for the worst offenders.Peer reviewedPost-prin

MorphoSys reconfigurable hardware for cryptography: The twofish case
No full textThis paper presents the mapping and performance analysis of the Twofish algorithm on MorphoSys. MorphoSys is a reconfigurable architecture that can provide high performance compared to custom hardware and yet preserves a level of flexibility compared to general-purpose processors.With today's high demand for secure data transfer mediums including wired and wireless networks, there is a growing demand for real-time implementation of cryptographic algorithms. The choice of the Twofish algorithm, one of the five AES finalists, is because it is computationally intensive algorithm. It requires lookup tables, logical and arithmetic computations that stipulate high flexibility and performance. So it is a perfect algorithm to be mapped in order to evaluate such hardware. © 2010 Springer Science + Business Media, Inc.Al-Khalidy M, 2004, INT C CURR ISS BUS I; Almaini AEA, 1994, ELECT LOGIC SYSTEMS; Bagherzadeh N, 2000, J VLSI SIGNAL PR MAR; Damaj I, 2002, LECT NOTES COMPUT SC, V2438, P1076; Diab H, 2003, ACS IEEE INT C COMP; Ferrandi F., 2005, Proceedings. 19th IEEE International Parallel and Distributed Processing Symposium; Galanis MD, 2005, IEEE INT SYMP CIRC S, P1206, DOI 10.1109-ISCAS.2005.1464810; Galanis MD, 2004, P FPGA FEBR 2004; Galanis MD, 2004, P 13 INT C FIELD PRO; Ghaffari F, 2007, LECT NOTES COMPUT SC, V4050, P179, DOI 10.1007-978-3-540-71528-3_12; Green D.H., 1986, MODERN LOGIC DESIGN; Hartenstein R, 2001, DESIGN AUTOMATION TE; Hauck S, 1998, CAN C FIELD PROGR DE; Itani M, 2004, IEEE ACS INT C PERV; Majzoub S, 2006, IEEE S SIGN PROC INF, P496; Majzoub S, 2003, ACS IEEE INT C COMP; Majzoub S, 2006, 6 INT WORKSH SYST ON; MOLLER L., 2006, P 19 ANN S INT CIRC, P44, DOI 10.1145-1150343.1150360; Nollet V, 2003, P INT C ENG REC SYST, P81; Pan CZ, 2003, DESIGN, AUTOMATION AND TEST IN EUROPE CONFERENCE AND EXHIBITION, PROCEEDINGS, P468; Schneier B., 1996, APPL CRYPTOGRAPHY PR; Schneier B., 1998, TWOFISH 128 BIT BLOC; Singh H, 2000, IEEE T COMPUT, V49, P465, DOI 10.1109-12.8595400
