A convenient synthetic route for the synthesis of biologically active functionalized piperidines usingZn(OAc)2.2H2O as a highly efficient catalyst via five-component reaction of aromatic aldehydes,anilines and β-ketoesters at ambient temperature has studied. Mild reaction conditions, simplicity ofoperation and work-up procedures with no necessity of chromatographic purification steps, theavaila...

A major bottleneck in automatic hardware synthesis is the time to place and route the netlist produced by a hardware compiler. This paper presents a method which exploits the syntax of the source program to guide its layout in a deviceindependent manner. The technique has been used in prototyping a hardware compiler for a commercially-available device, the Algotronix CAL1024 FieldProgrammable G...

VLSI technology scaling has caused interconnect delay to increasingly dominate the overall chip performance. A design that satisfies timing constraints after logic synthesis will not necessarily meet timing constraints after place-androute due to wire delays. Physical synthesis has been emerged as a necessary weapon for design closure. It is a core component of modern VLSI design methodologies ...

One pot solvent less synthesis of amidoalkylnaphthol derivatives via reaction of aldehydes, 2-naphthol and acetamide/urea in the presence of phenylphosphinic acid is  described. This methodology provides a simple synthetic route to amidoalkylnaphthols in good to high yields.   

An efficient synthesis route to 1,4-dihydropyrimidine derivatives from reaction of divergent aldehydes with ethylacetoacetate and urea under solvent-free conditions by ZnO nanoparticles as a relative in expansive, eco-friendly, easy available, non-volatile, non-explosion, thermally robust, recyclable and easy to handle catalyst at 90°C with excellent yields is described. Unenhanced reaction tim...

In the past decades, many methods have been developed to synthesize zero- dimensional  nanoparticles, quasi–one–dimensional (1D) CuO nanostructures, such as metal organic deposition technique,  microwave irradiation, sol-gel-like dip  technique, reverse micelle-assisted route, chemical method, and simple template free solution route. Among those synthesis methods, hydrothermal and chemical reac...

We have continued development of Optically Reconfigurable Gate Arrays (ORGAs) to realize larger virtual gate count VLSIs than currently available VLSIs. The grain and structure of ORGAs must be changed depending on their dynamically reconfigurable applications. Therefore, an ORGA development tool must be easily customizable for changes of the grain and structure. This paper presents an easily-c...
