We describe a new image coding approach in which a 4-ary arithmetic coder is used to represent signiicant coeecient values and the lengths of zero runs between coeecients. This algorithm works by raster scanning within subbands, and therefore involves much lower addressing complexity than other algorithms such as zerotree coding that require the creation and maintenance of lists of dependencies...

We present a new model of gene expression, which relies on an interpretation with a stack. We rst give an outline of the main morphogenic evolutionary computation approaches, and bring out the properties we wish to have from a gene expression model used to build structures. Then we present our model and an application of its principles. Finally, we give a discussion on the properties of the mod...

Current implementations of Java make security decisions by searching the runtime call stack. These systems have attractive security properties, but they have been criticized as being dependent on specific artifacts of the Java implementation. This paper models the stack inspection algorithm in terms of a well-understood logic for access control and demonstrates how stack inspection is a useful ...

In a strategic framework, combinators provide a fundamental mechanism for exercising control over rewriting. This type of control is based on the observation of the success or failure of strategy application. This paper describes a framework where information relating to the outcome of strategy application is stored in two internally maintained stacks. These stacks represent an implicit state w...

Some recent work in the field of Genetic Programming (GP) has been concerned with finding optimum representations for evolvable and efficient computer programs. In this paper, I describe a new GP system in which target programs run on a stack-based virtual machine. The system is shown to have certain advantages in terms of efficiency and simplicity of implementation, and for certain classes of ...

Electrical double layer supercapacitor is very significant in the field of electrical energy storage which can be the solution for the current revolution in the electronic devices like mobile phones, camera flashes which needs flexible and miniaturized energy storage device with all non-aqueous components. The multiwalled carbon nanotubes (MWNTs) have been synthesized by catalytic chemical vapo...

A k-stack layout (respectively, k-queue layout) of a graph consists of a total order of the vertices, and a partition of the edges into k sets of non-crossing (non-nested) edges with respect to the vertex ordering. A k-track layout of a graph consists of a vertex k-colouring, and a total order of each vertex colour class, such that between each pair of colour classes no two edges cross. The sta...

With the growing focus on energy efficiency, it is important to find ways to reduce energy without sacrificing performance. The L1 data cache is a significant contributor to processor energy consumption. We advocate treating data from the program’s stack differently from non-stack data to reduce energy. We characterize stack accesses to determine how they differ from general memory accesses in ...

Continuation-passing style (CPS) is often criticized to be more expensive than the usual direct style of functional programming. By structure, CPS functions indeed are passed one extra argument (the continuation), and each intermediate result indeed occurs in a function call (to the continuation). As higher-order functions, continuations are also more expensive. However, by structure also, CPS ...

The LOD2 Stack is an integrated distribution of aligned tools which support the whole life cycle of Linked Data from extraction, authoring/creation via enrichment, interlinking, fusing to maintenance. The LOD2 Stack comprises new and substantially extended existing tools from the LOD2 project partners and third parties. The stack is designed to be versatile; for all functionality we define clea...
