Average outage duration of multihop communication systems with regenerative relays
(
IEEE
, 2005 , Article)
Closed-form expressions for the average outage duration (AOD) of multihop regenerative communication systems over generalized fading channels are presented. Both noise-limited and interference-limited systems are studied. ...
On the capacity of cooperative diversity systems with adaptive modulation
(
IEEE
, 2005 , Conference)
In recent years, cooperative diversity systems have gained increased attention in the literature as a new way of combating the effect of signal fading. In this paper, we investigate the performance of these systems when ...
A high precision resolver-to-DC converter
(
IEEE
, 2005 , Article)
A newly developed resolver converter, providing a pseudolinear voltage proportional to the shaft angle, is presented. This converter is based on a new concept involving the absolute values of the demodulated sine and cosine ...
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 ...
Applications of virtual construction environments in improving construction site safety
(
10th International Conference on Civil, Structural and Environmental Engineering Computing, Civil-Comp 2005
, 2005 , Conference)
The complex nature of construction site safety during construction is a major issue to be considered. Among the top reasons affecting the safety of the construction site is the available workplace and the surrounding ...
Baseline formation for damage diagnosis in a turbine blade
(
Aalborg University
, 2005 , Conference)
In the absence of a baseline for the pre-damaged structures, an attempt is made to create one, analytically, using dimensional analysis and physically using stereolithography. First, a preliminary diagnosis check is performed ...
Novel potentiometric copper (II) selective membrane sensors based on cyclic tetrapeptide derivatives as neutral ionophores
(
Elsevier
, 2005 , Article)
Two novel membrane sensors sensitive and reasonably selective for Cu2+ ions are described. These are based on the use of newly synthesized cyclic tetrapeptide derivatives as neutral ionophores and sodium tetraphenylborate ...
Novel biomedical sensors for flow injection potentiometric determination of creatinine in human serum
(
Wiley-VCH Verlag
, 2005 , Article)
Coated-wire (CW) and tubular (Tu) type membrane sensors for creatinine are developed. These consist of creatinine tungstophosphate(CTP), creatinine molybdophosphate (CMP) and creatinine picrolonate (CPC) ion-pair complexes ...
Electronic, infrared, and Raman spectral studies of the reaction of iodine with 4-aminopyridine
(
Elsevier
, 2005 , Article)
The reaction of iodine as an electron acceptor with the base 4-aminopyridine (4APY) has been investigated spectrophotometrically in chloroform at room temperature. The electronic absorptions, infrared and Raman spectra, ...
Spectroscopic studies on the reaction of iodine with the mixed oxygen-nitrogen cyclic base 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8,8,8] hexacosane
(
Chemical Publishing Co.
, 2005 , Article)
The interaction of the mixed oxygen-nitrogen cyclic base, 4,7,13,16,21,24-hexaoxa-1,10- diazabicyclo[8,8,8] hexacosane (HODABCHC) with iodine as a s-acceptor has been studied spectrophotometrically at room temperature in ...
