In this paper, three novel designs of broadband patch antenna are proposed. The first design propose broadband slotted equilateral triangular patch antenna (ETPA) operating on frequency around 1800 MHz. The second design propose broadband slotted right angle isosceles triangular patch antenna RAITPA operating on frequency around 2400 MHz. The third design proposes wideband V-Slotted and shorted...

Sequential place and route tools for field programmable gate arrays (FPGA’s) are inherently weak at addressing both wirability and timing optimizations. This is primarily due to the difficulty of accurately predicting wirability and delay during placement. A set of new performancedriven simultaneous placement/routing techniques has been developed for both row-based and island-style FPGA designs...

The LaHave House Project explores the creation of an automated architectural design service based on an industrial design approach to architecture in which Architects design families of similarly structured objects, rather than individual ones. Our current system consists of three software components: 1) A design engine that uses shape grammars to generate a library of preliminary level house d...

-We describe a neural information retrieval system developed for retrieval o f engineering designs. Twodimensional ( 2-D ) and three-dimensional ( 3-D ) representations of engineering designs are input to adaptive resonance theory (ARTI ) neural networks to produce groups or clusters of similar parts. ARTI networks are first trained to cluster designs into families, and then to recall a family ...

I present an Hipparcos color-magnitude diagram (CMD) that is color-coded by transverse velocity v ⊥. This illustrates the connection between the photomet-ric and kinematic properties of various stellar populations in a manner that is particularly suitable to introductory astronomy courses.

Measuring the quality of metadata is only possible by assessing the quality of the underlying schema and the metadata instance. We propose some factors that are measurable automatically for metadata according to the CMD framework, taking into account the variability of schemas that can be defined in this framework. The factors include among others the number of elements, the (re-)use of reusabl...

In recent years the popularity of hybrid filter bank technologies for analog-to-digital conversion (HFB ADC) has increased and they have found their way from the academic world to industrial applications. Hybrid filter bank designs are based on an established mathematical framework for optimized converter designs. TimeInterleaved ADC (TIADC) technologies have a much longer history; nevertheless...

In this paper we present a word-level model checking method that attempts to speed up safety property checking of industrial netlists. Our aim is to construct an algorithm that allows us to check both bounded and unbounded properties using standard bit-level model checking methods as back-end decision procedures, while incurring minimum runtime penalties for designs that are unsuited to our ana...

The paper describes an efficient method to prove equivalence between two integer arithmetic datapath designs specified at the register transfer level. The method is illustrated with an industrial ALU design. As reported in literature, solving it using a commercial equivalence checking tool required casesplitting, which limits its applicability to larger designs. We show how such a task can be s...

A persistent criticism of analog synthesis techn;ques is that they cannot cope with the complexity of realistic industrial designs, especially system-level designs. We show how recent advances in simulation-based synthesis can be augmented, via appropriate macromodeling, to attack complex analog blocks. To support this claim, we resynthesize from scratch, in several different styles, a complex ...
