Stability and dynamics of a controlled van der Pol-Duffing oscillator

Ji Jin; Hansen Colin (Elsevier, 2006)

The trivial equilibrium of a van der Pol-Duffing oscillator under a linear-plus-nonlinear feedback control may change its stability either via a single or via a double Hopf bifurcation if the time delay involved in the ...
Stability and stabilisation of switched linear dynamic systems with time delay and uncertainties

Hien L.; Ha Quang; Phat V (Elsevier Science Inc, 2009)

This paper considers the problem of exponential stability and stabilization of switched linear time-delay systems. The system parameter uncertainties are time-varying and unknown but norm-bounded. The delay in the system ...
Static Output Feedback Control for Electrohydraulic Active Suspensions via T-S Fuzzy Model Approach

Du Haiping; Zhang Nong (Asme-Amer Soc Mechanical Eng, 2009)

The paper presents a fuzzy static output feedback controller design approach for vehicle electrohydraulic active suspensions based on Takagi-Sugeno (T-S) fuzzy modeling technique. The T-S fuzzy model is first applied to ...
Static replication of forward-start claims and realized variance swaps

Baldeaux Jan; Rutkowski Marek (Routledge, 2010)

The goal of this work is to examine the static replication of path-dependent derivatives such as realized variance swaps, using more standard products such as forward-start binary (i.e. digital) double calls and puts. We ...
Statistical Foundations of Intelligent Technologies

Aboura Khalid (University of Technology, Sydney, 2007)

Intelligent Technologies problems have one common element; uncertainty. Randomness, natural or created, is an important part of the engineering problems in Intelligent Technologies. Modeling it properly and dealing with ...
Statistical laboratories using Minitab, SPSS and Excel: a practical comparison

Reid, A.; Prvan, T.; Petocz, P. (Blackwell Publishing, 2007)

This article discusses three statistical laboratories - on descriptive statistics, statistical inference and regression - for introductory statistics courses. They are presented in Minitab, SPSS (Statistical Package for ...
Statistics and the Peer Review Process in Construction Research

Best Eric; Smith Narelle (Queensland University of Technology, 2005)

This paper examines, in some detail, two papers published in 2003 and 2004 in respected journals. The papers had been through a typical peer review process, with one of the journals in question using four referees rather ...
A steel-concrete composite beam element with material nonlinearities and partial shear interaction

Valipour Goudarzi Hamid Reza; Bradford Mark (Elsevier Inc, 2009)

This paper presents the formulation of a novel force-based 1D steel-concrete composite element that captures material nonlinearities and partial shear interaction between the steel profile and the reinforced concrete slab. ...
STEF: Personalized trade exhibition recommendation

Guo Xuetao; Lu Jie (Joint Conference On Information Sciences, 2005)

In this study, a novel recommendation technique is proposed by integrating the user-based and item-based recommendation approaches. A recommender system, called Smart Trade Exhibition Finder (STEF), is proposed to ...
The Stochastic Bifurcation Behaviour of Speculative Financial Markets

Chiarella Carl; He Xuezhong; Wang Duo; Zheng Min (Elsevier Science BV, 2008)

This paper establishes a continuous-time stochastic asset pricing model in a speculative financial market with fundamentalists and chartists by introducing a noisy fundamental price. By application of stochastic bifurcation ...
Stochastic Deterioration Processes for Bridge Lifetime Assessment

Li Jianchun; Aboura Khalid; Crews Keith; Samali Bijan (IEEE, 2008)

The Markov chain model can be found in the maintenance and repair problems since the early 60's, is introduced to the maintenance of road infrastructure in the 1980's, and is made to drive the current bridge maintenance ...
Stock market, interest rate and output: a model and estimation for US time series data

Semmler Willi; Mittnik Stefan; Chiarella Carl; Zhu Peiyuan (Berkeley Electronic Press, 2002)

In this paper we construct a model of stock market, interest rate and output interaction which is a generalization of the well known 1981 model of Blanchard. We allow for imperfect substitutability between stocks and ...
Streamlined variance calculations for semiparametric mixed models

Smith Andrew; Wand Matt (John Wiley & Sons Ltd., 2008)

Semiparametric mixed model analysis benefits from variability estimates such as standard errors of effect estimates and variability bars to accompany curve estimates. We show how the underlying variance calculations can ...
Strong Approximations of Stochastic Differential Equations with Jumps

Platen Eckhard; Bruti Liberati Nicola (Elsevier, 2007)

This paper is a survey of strong discrete time approximations of jump-diffusion processes described by stochastic differential equations (SDEs). It also presents new results on strong discrete time approximations for the ...
Strong Predictor-Corrector Euler Methods for Stochastic Differential Equations

Bruti Liberati Nicola; Platen Eckhard (World Scientific, 2008)

This paper introduces a new class of numerical schemes for the pathwise approximation of solutions of stochastic differential equations (SDEs). The proposed family of strong predictor-corrector Euler methods are designed ...
A Structural Model with Unobserved Default Boundary

Schmidt Thorsten; Novikov Alex (Routledge, 2008)

A firm-value model similar to the one proposed by Black and Cox (1976) is considered. Instead of assuming a constant and known default boundary, the default boundary is an unobserved stochastic process. Interestingly, this ...
A structure for general and specific market risk

Platen Eckhard; Stahl Gerhard (National Strength and Conditioning Association, 2007)

The paper presents a consistent approach to the modeling of general and specific market risk as defined in regulatory documents. It compares the statistically based beta-factor model with a class of benchmark models that ...
Students Experience of Learning in Statistics

Petocz Peter; Reid Anna (National Inquiry Services Centre, 2001)

It is obvious from the quality of assessment tasks and the level of classroom interactions that students sitting in the same classes learn in very different ways. Often these tasks and interactions are the only windows ...
Summation of Reciprocals which involve products of terms from generalised Fibonacci sequences - Part II

Melham, R. S (Fibonacci Association, 2001)
Sums Involving Fibonacci and Pell Numbers

Melham Ray (European Mathematical Society Publishing House, 1999)

SUMS INVOLVING FIBONACCI AND PELL NUMBERS
