The value of using a higher radix for modular multiplication in the context of RSA is investigated. The main conclusion is that for algorithms which perform the multiplication via repeated addition, there is, broadly speaking, a direct trade-off between space and time provided by change of radix. Thus chip area utilised is roughly proportional to speed. However, initially as the radix is increa...

Weuse extensive seeing and low-atmospheremeteorological data obtained at the European Southern Observatory’s La Silla complex in Chile, and at the proposed site of the Very Large Telescope atCerro Paranal. The differences in seeing between these two locations are studied. A prototype system is set up for predicting seeing values, given knowledge of the meteorological environment. A novel patter...

The following is a short survey of the recent developments, legislative and administrative, affectingmental welfare work in general, and including matters especially concerning the Central Association. Broadly speaking, the year has been one of steady progress. The appointment of the Royal Commission on Lunacy and Mental Disorders testifies to the public interest taken in questions affecting th...

Broadly speaking, MR imaging techniques can be divided into two groups: those that use extrinsic contrast agents and those that do not. Contrast-enhanced methods for imaging angiogenesis: • Dynamic contrast-enhanced (DCE) MRI using low molecular weight agents (<1,000 Daltons) that rapidly diffuse in the extracellular fluid space (ECF agents) • DCE-MRI using large-molecular agents (>30,000 Dalto...

We generalize the selective-ID security model for HIBE by introducing two new security models. Broadly speaking, both these models allow the adversary to commit to a set of identities and in the challenge phase choose any one of the previously committed identities. Two constructions of HIBE are presented which are secure in the two models. Further, we show that the HIBEs can be modified to obta...

Project objectives 1. Broadly speaking, my objective is to change the way the US Trade Representative’s Office approaches the issue of tobacco. Tobacco is not a ‘good’ that should be traded and sold like any other consumer product in the market. It is dangerous and lethal and must not be afforded the same trade protections granted to other goods and services. 2. Create a coalition within the me...

The interface of developmental neuroimaging with developmental neurotoxicology can, broadly speaking, address two complementary concerns. The first is to study the impact of specific exposures on brain development. The second is to study known neurobehavioral disorders with an eye to discerning toxicological contributions to pathogenesis. Pathogenesis targets brain based upon physical propertie...

Wireline and wireless communication devices (modems – DSL and cable and WiFi – and cellular radios) are the workhorses that drive the modern information age. Their central goal is to move around the basic digital currency of the information: bits. This movement is done on physical media, either via wires or via wireless. The key challenge is that the input-output relationship of the physical me...

Tomorrow’s architectural practitioners seemingly need to gain an overview of, if not master, a wide range of computer aided architectural design applications, from image making to Building Information Modelling (BIM) to digital fabrication. However, we are sceptical whether there is wide recognition that there is value in a broader appreciation of the underlying principles that organize these a...

Broadly speaking, cryptography is the problem of doing communication or computation involving two or more parties who may not trust one another. The best known cryptographic problem is the transmission of secret messages. Suppose wish to communicate in secret. For example, you may wish to give your credit card number to a merchant in exchange for goods, hopefully without any malevolent third pa...
