Where AES is for Internet, SIMON could be for IoT
No full textAbstractWith the upcoming era of Internet of Things and the Pervasive Computing, there is a need to develop block ciphers with tight constraints such as area, power, memory, performance, throughput and others. These are so called the lightweight block ciphers which are specifically intended for resource constrained platforms. Lined up in the line is SIMON, a light weight block cipher proposed by NSA after the prompting from the U.S. Government in the year 2013 along with SPECK lightweight block cipher. SIMON implementation on hardware has excellent results in terms of area and has been found to be a very strong alternative to the existing AES. This paper involves the basic design considerations, round functions, key schedule and parameters of SIMON and also we can look forward into the implementations of SIMON in hardware comparing with the existing AES standard. This paper also focuses on the analysis in terms of area, power and delay of the SIMON 64/128 configuration in Cadence Synthesis RTL Compiler using the CMOS 180 nm and 90 nm technology libraries
Forecasting banknotes
No full textA central bank’s liquidity forecast is important in ensuring that it supplies the banking system’s need for central bank money. Banknote (or currency in circulation) demand is the largest and for some central banks the most variable component of the liquidity forecast. Accurate forecasting of banknotes is essential in ensuring an accurate liquidity forecast and in turn effective monetary policy implementation. This Handbook discusses these issues and outlines a structural time series state space (STSSS) model which is now used by central banks including the Bank of England and ECB to forecast banknotes (currency in circulation).Forecasting banknotes

No full textModeling and interpreting element ratios in water and sediments: A sensitivity analysis of post-Chernobyl Ru : Cs ratios.
No full textWhen elements are simultaneously added to lakes, experimentally or by accident, their ratios in the water phase and in bottom sediments can change with time due to differential partitioning between solution and suspended particles or sediments. A number of equations are developed to show the change of ratio with time in water and sediments assuming simultaneous pulse inputs followed by a range of combinations of loss processes from solution (i.e. hydraulic losses, sorption to particles followed by settling, and diffusion into the sediments). The pattern of events is discussed both for pulse events with specific limiting assumptions and for combined continuous and pulse inputs. The models show that elemental ratios in sediments are generally less sensitive indicators of differential partitioning than are elemental ratios in water. For lakes with long residence times, the long-term elemental ratio in the sediments does not differ from that in the initial spike to the water column, but for short residence times, it is directly dependent on the ratio of either partition or diffusion coefficients. The models are used to interpret Ru : Cs ratios measured in the water and sediments of Esthwaite Water subsequent to the pulse input of Chernobyl fallout. The ratios can be explained by assuming nuclides were lost either by flushing and sorption or by flushing, sorption, and diffusion. The process combination of flushing and diffusion is incompatible with the observed constant ratios
CS Decomposition Based Bayesian Subspace Estimation
No full textIn numerous applications, it is required to estimate the principal subspace of the data, possibly from a very limited number of samples. Additionally, it often occurs that some rough knowledge about this subspace is available and could be used to improve subspace estimation accuracy in this case. This is the problem we address herein and, in order to solve it, a Bayesian approach is proposed. The main idea consists of using the CS decomposition of the semi-orthogonal matrix whose columns span the subspace of interest. This parametrization is intuitively appealing and allows for non informative prior distributions of the matrices involved in the CS decomposition and very mild assumptions about the angles between the actual subspace and the prior subspace. The posterior distributions are derived and a Gibbs sampling scheme is presented to obtain the minimum mean-square distance estimator of the subspace of interest. Numerical simulations and an application to real hyperspectral data assess the validity and the performances of the estimator
Towards the tumble resistant microlight
No full textThe tumble mode is a pitching departure from controlled flight which leads to a pitch autorotation that is generally unrecoverable – resulting in vertical ground impact, usually preceded by in-flight breakup (the mechanism for which, surprisingly, can sometimes prevent loss of life). This was identified in work led by the British Microlight Aircraft Association beginning in 1997 as a response to a number of fatal accidents in Rogallo winged microlight aeroplanes, although the tumble is also known to occur to hang-gliders. This paper explains how this class of aeroplane is controlled, and how it has been found that they can enter the tumble mode. The mechanism by which the tumble can be entered is described. This has led to work showing how flight testing can be used to establish and demonstrate resistance to tumble entry – particularly important with increasing number of very high performance flexwings. These flight tests will be explained, together with the significance of the results. Recent accident investigation work has also shown a new mechanism of tumble entry, through partial failure of the A-frame structure and the pitch-trimmer mechanism. Also described is a possible relevance to well known historical accidents to flying wing aeroplanes– specifically the YB-49 and dH-108, and discovered data on the characteristics of the BKB-1flying wing glider; are also described
A production and production book of Neil Simon's God's Favorite.
No full textThis thesis is the author's approach to directing and designing Neil Simon's God's Favorite for production on the stage of the Jones Theatre at Baylor University. It contains a biography of the playwright, including parallel elements in his works from life, and several critical reviews. This thesis analyzes the structural elements of the play: idea, dramatic action, character, dialogue, mood, tempo, and given circumstances. It also includes a discussion of the detailed design approach. All elements of the play's design are explored: setting, properties, lighting, costumes, sound, and make-up. In addition, the thesis discusses the casting, rehearsals, and performances. Illustrations and charts included are: a ground plan, properties list, light plot, lighting instrument schedule, costume plot, sound cue schedule, make-up chart, scenery, lighting and costume photographs. The final chapter is the prompt book. Found in the appendix is the pre-production publicity and a copy of the program
