Cryptanalysis of image encryption with compound chaotic sequence
(IEEE, 2009)
Recently, an image encryption algorithm based on compound chaotic sequence was proposed [Tong et al., Image and Vision Computing 26 (2008) 843]. In this paper, we analyze the security weaknesses of the proposal. We give ...
Update and revision of Turkish air quality regulation
(Inderscience Enterprises LTD, 2009)
The Air Quality Assurance Regulation (AQAR) was issued on October 1986. This regulation was basically a direct translation of the German TA-Luft of 1984. The main purpose of AQAR was to control the effect of industry, ...
Largest eigenvalues of the discrete p-Laplacian of trees with degree sequences
(Int Linear Algebra Soc, 2009-03)
Trees that have greatest maximum p-Laplacian eigenvalue among all trees with a given degree sequence are characterized. It is shown that such extremal trees can be obtained by breadth-first search where the vertex degrees ...
Comment on "Modified Baptista type chaotic cryptosystem via matrix secret key" [Phys. Lett. A 372 (2008) 5427]
(Elsevier Science BV, 2009-09-07)
In this comment, we analyze a recently proposed Baptista-like cryptosystem and show that it is not invertible. Others weaknesses are also reported. A modified version of this cryptosystem is proposed to show how to overcome ...
Incremental construction of classifier and discriminant ensembles
(Elsevier Science Inc, 2009-04-15)
We discuss approaches to incrementally construct an ensemble. The first constructs an ensemble of classifiers choosing a subset from a larger set, and the second constructs an ensemble of discriminants, where a classifier ...
Spectral correlation of a digital pulse stream modulated by a cyclostationary sequence in the presence of timing jitter
(IEEE-INST Electrical Electronics Engineers Inc, 2009-02)
Cyclostationarity is an inherent characteristic of many communication signals, which can be exploited for performing various signal processing tasks. Imperfections in the signal generation that affect the cyclic statistics ...

Virtual team effectiveness using dyadic teams
(IEEE, 2007)
The importance of effectiveness for virtual teamwork continues to gain momentum as technology and globalization of work accelerate. The implementation of virtual teams provides one approach to enhance competitiveness, ...
In situ fluorescence study of swelling, sorption and desorption processes in and out of PAAm gels
(Wiley-V C H Verlag GMBH, 2008-05)
Small molecule sorption and desorption in and out of polyacrylamide (PAAm) gels were studied at various temperatures. Pyranine (P(y)) dissolved in water used as a probe. Fluorescence emission intensity, I(p) from P(y) was ...
An integrated circuit with transmit beamforming flip-chip bonded to a 2-D CMUT array for 3-D ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2009-10)
State-of-the-art 3-D medical ultrasound imaging requires transmitting and receiving ultrasound using a 2-D array of ultrasound transducers with hundreds or thousands of elements. A tight combination of the transducer array ...
