The slime mould Physarum polycephalum is a suitable candidate organism for soft-matter robotics because it exhibits controllable transport, movement and guidance behaviour. Physarum may be considered as a smart computing and actuating material since both its motor and control systems are distributed within its undifferentiated tissue and can survive trauma such as excision, fission and fusion o...

Abstract— This review paper presents a study about entity search engine .It describes details about entity search engine architecture and it’s working or the different methods adopted for entity extraction on it. All these methods are described based on the working examples such as entity cube and Microsoft academic search. Search engine for searching the summaries of an entity that make the us...

Software developers have observed that certain parts of their applications are more change-prone than others. For example, for product-centric applications such as those that determine premiums for insurance policies or rates for calling plans, the most dynamic elements are the business rules that govern how products and services are priced and promoted. Likewise, for process-centric applicatio...

A method of self-aligned, microcontact printing that avoids the need for dedicated alignment and stamping equipment is demonstrated. Complete miniature print engines combining elastically supported print heads with alignment structures that mate with corresponding features on etched substrates to allow mechanical registration are constructed from silicon parts. The impression can be transferred...

An engine is a programming language abstraction that implements timed preemption. Engines form a useful mechanism where bounded computation is needed. We describe an implementation of engines in Common Lisp and illustrate its functionality. We conclude with a discussion on how engines are being used in an ongoing project about goal-driven explanation. This paper is also an exercise in writing a...

A Color Matching Method (CMM), also called a Color Engine, is a software component that does the color conversion calculations from one device's color space to another. This paper discuses a new working mode for CMMs that allows such software components to operate in a way that is not restricted by the gamut of the device encoding, the gamut of the profile connection space or any intermediate s...

In this paper, electrical heat engines driven by the Johnson-Nyquist noise of resistors are introduced. They utilize Coulomb’s law and the fluctuation–dissipation theorem of statistical physics. In these engines, resistors, capacitors and switches are the building elements. For best performance, a large number of parallel engines must be integrated to run in a synchronized fashion, and the size...

XML databases lie at the conjunction of two disparate themes and have to address issues related to both. On one hand there is the traditional database field of structured data, query languages, algebras, logical and physical plans while on the other hand is the new standard of the eXtensible Markup Language (XML) for storing and disseminating semi-structured data over the web. This paper focuse...

I n surgery, to underscore safety processes, we love to make comparisons with other industries like flying. Recently, I found myself making a similar comparison to car racing. I was privileged to spend a weekend in a race car run by a professional race team. This crew ran an incredibly well-oiled machine, not only literally but also metaphorically. They raced at 24 Hours of Daytona, keeping a c...

We introduce a new programming language construct, Interactors, supporting the agent-oriented view that programming is a dialog between simple, self-contained, autonomous building blocks. We define Interactors as an abstraction of answer generation and refinement in Logic Engines resulting in expressive language extension and metaprogramming patterns, including emulation of Prolog’s dynamic dat...
