A modular analogue neuro-chip set with on-chip learning capability is developed for active noise canceling. The analogue neuro-chip set incorporates the error backpropagation learning rule for practical applications, and allows pin-to-pin interconnections for multi-chip boards. The developed neuro-board demonstrated active noise canceling without any digital signal processor. Multi-path fading ...

An optimization approach is presented for enumerating pin-jointed bistable compliant mechanisms. In the first stage, the statically determinate trusses with non-crossing members containing a given set of nodes and some pre-defined members are regarded as minimally rigid framework or a Laman framework, and are enumerated without repetitions by the graph enumeration algorithm. In the second stage...

Accurate measurement of photon flux from an X-ray source, a parameter required to calculate the dose absorbed by the sample, is not yet routinely available at macromolecular crystallography beamlines. The development of a model for determining the photon flux incident on pin diodes is described here, and has been tested on the macromolecular crystallography beamlines at both the Swiss Light Sou...

The number, shape and sizes of intermuscular bones have been studied in table size (around 1200g). rohu, catla and mrigal after microwave cooking and dissection. Carp intermuscular bones have varied shape and size. These bones are of two types, Y pin bones and straight pin bones. Total number of pin bones are highest in mrigal (110 nos.) followed by catla (108 nos.) and rohu (104 nos.). Y pin b...

Responding to the PIN cracking attacks from Berkman and Ostrovsky (FC 2007), we outline a simple solution called salted-PIN. Instead of sending the regular user PIN, salted-PIN requires an ATM to generate a Transport Final PIN from a user PIN, account number, and a salt value (stored on the bank card) through, e.g., a pseudo-random function. We explore different attacks on this solution, and pr...

Fins are protrusions on a heat transfer surface to augment heat transfer rate from it. The increase in area exposed to convection in case of finned surfaces results in increased heat transfer rate. In this study heat transfer characteristics of a pin fin with perforation is numerically analyzed. A pin fin is fabricated and experiments are done under forced convection conditions. The experimenta...

Friction stir welding (FSW) tool pin, as a critical component of FSW tool, plays an important role in determining the final joint properties by affecting heat generation, plastic material flow, loads, and so on. However, effects pin on mass transfer are not elucidated quantitative studied. In present study, validated model was adopted to quantitatively analyze size taper angle thermal process f...

INTRODUCTION Over-expression of penile neuronal nitric oxide synthase (PnNOS) from a plasmid ameliorates aging-related erectile dysfunction (ED), whereas over-expression of the protein inhibitor of NOS (PIN), that binds to nNOS, increases ED. AIM To improve this form of gene therapy for ED by comparing the electrical field response of short hairpin RNA (shRNA) for PIN with that of antisense P...
