Composite sandwich structures for crashworthiness applications
(2007 , Article)
Fibre-reinforced polymer sandwiches are promising materials for reducing vehicle mass, thereby improving the fuel economics. Nonetheless, to fully explore these materials as the primary structures and energy absorbers in ...
Novel linearizer for tangent/cotangent converter
(
IEEE
, 2009 , Conference)
Resolvers and other types of sinusoidal encoders provide electrical signals whose amplitudes are related to the sine and cosine of the mechanical shaft angle ¿ over the full 360° range. The tangent/cotangent converter, ...
A novel amplitude-to-phase converter for sine/cosine position transducers
(
Taylor and Francis Group
, 2007 , Article)
Resolvers and various other types of sine/cosine encoders are used for both angular and linear position sensing. These devices provide analogue signals in the form of the sine and the cosine of an angle related to the ...
A new closed-loop converter for sinusoidal encoders - Preliminary results
(
IEEE
, 2009 , Conference)
Sinusoidal position transducers provide accurate and reliable representation of the mechanical position of their shafts. The sine/cosine transducers signals may be used in open loop or closed loop arrangements for the ...
Assessment of water bodies of united arab emirates coastal sabkhas as potential sites for natural salinity gradient solar ponds
(
ASCE - American Society of Civil Engineers
, 2008 , Article)
Increasing population and growing demands from both agriculture and industry in the United Arab Emirates (UAE) necessitate the need to provide inexpensive fresh water. The only feasible source of such water is desalination. ...
Efficient visual mixture design of experiments using property clustering techniques
(2009 , Article)
Mixture design is a design of experiments (DOE) tool used to determine the combination of chemical constitutents that deliver a desired response (or property) using a minimum number of experimental runs. While the approach ...
Precise, wide-range approximations to arc sine function suitable for analog implementation in sensors and instrumentation applications
(
IEEE
, 2005 , Article)
This paper presents four newly developed algebraic approximations of the inverse sine function, defined for the full [-1,+1] input range. These approximations contain few terms, and have numerical coefficients with low ...
Design and Assembly of Miniature Zirconia Oxygen Sensors
(
IEEE
, 2004 , Article)
Zirconia oxygen sensors are highly selective solid-state devices used for many applications, including combustion control for better fuel economy and lower emissions. Stabilized zirconia electrolyte meets the device ...
Theory and simulation of a miniature zirconia sensor for control of the air-to-fuel ratio in combustion systems
(
IEEE
, 2001 , Article)
The theory of operation on both sides of stoichiometry of a miniature zirconia oxygen pump-gauge incorporating a diffusion hole is discussed. Computer simulation of the sensor output when used for monitoring the air-to-fuel ...
Flow induced vibrations of pressure let-down station in QATARGAS
(2006 , Conference)
The use of the pipes to transfer oil and gases from production to export places is a common application in oil and gas industries. The safety and stability of the pipelines are crucial to prevent human and equipment losses. ...
