A number of small size pixels for CMOS image sensors using just one row line to control reset and select transistors has been designed, fabricated and characterized. The elimination of an additional control line and the associated contacts provides more pixel area that can be allocated to the photodiode. On one hand, this gives a substantially higher pixel fill factor, consequently higher quant...

This paper enumerates a low power, high speed design of flip-flop having less number of transistors. In flip-flop design only one transistor is being clocked by short pulse train which is known as True Single Phase Clocking (TSPC) flip-flop. The true single-phase clock (TSPC) is common dynamic flip-flop which performs the flip-flop operation with little power and at high speeds. In this paper, ...

The effect of casting pores on the very high cycle fatigue (VHCF) behavior of a directionally solidified (DS) Ni-base superalloy DZ4 is investigated. Casting and hot isostatic pressing (HIP) specimens were subjected to very high cycle fatigue loading in an ambient atmosphere. The results demonstrated that the continuously descending S-N curves were exhibited for both the casting and HIP specime...

The article presents pr ocess application of the rapi d prototyping (RP) for manufacturing of blades of aircraft turbine in monocrystallization and also directional crystallization of casting process. It is describing the method of modelling of the chosen elements of casting model kit with the usage of RP and RT system s. The article presents the analysis of additive rapid prototyping methods (...

In recent years, casting molds made by sand-type additive manufacturing (AM) technology are increasingly being used to build prototypes and small-lot production products.

A hierarchical decomposition of a simple polygon is introduced. The hierarchy has depth O(log n), linear size, and its regions have at most three neighbors. Using this hierarchy, circular ray shooting queries in a simple polygon can be answered in O(log n) query time and O(n log n) space. If the radius of the circle is xed, the query time can be improved to O(log n) and the space to O(n).

Polydimethylsiloxane (PDMS) has numerous desirable properties for fabricating microfluidic devices, including optical transparency, flexibility, biocompatibility, and fabrication by casting; however, partitioning of small hydrophobic molecules into the bulk of PDMS hinders industrial acceptance of PDMS microfluidic devices for chemical processing and drug development applications. Here we descr...
