Experiments were performed to determine the effect of community composition on system function (bacterial production) in arctic Alaska. In this system bacterial production is controlled by: community, temperature, nutrients, and carbon source. Lake inlet and outlet communities in these experiments were different in composition, based on PCR-DGGE fingerprinting of 16S rDNA. For both communities,...

A numerical method for a class of forward-backward stochastic differential equations (FBSDEs) is proposed and analyzed. The method is designed around the Four Step Scheme (Douglas-Ma-Protter, 1996) but with a Hermite-spectral method to approximate the solution to the decoupled quasilinear PDE on the whole space. A rigorous synthetic error analysis is carried out for a fully discretized scheme, ...

Implicit-explicit (IMEX) linear multistep methods are examined with respect to their suitability for the integration of fast-wave, slow-wave problems in which the fast wave is physically insignificant and need not be accurately simulated. The widely used combination of trapezoidal implicit and leapfrog explicit differencing is compared to schemes based on 5 Adams methods or on backward differen...

The change point model (CPM) framework introduced in Hawkins, Qiu, and Kang (2003) and Hawkins and Zamba (2005) provides an effective and computationally efficient method for sequentially detecting multiple changes points in streams of Gaussian random variables, when no information is available regarding the parameters of the distribution in the various segments. It has since been extended in v...

In this study, position control of a SCARA robot manipulator is investigated using the sliding mode (SMC) method based on parameter optimization The Bees Algorithm. modeling conducted in MSC Adams and implementation carried out MATLAB software. numerical model acquired by setting up virtual prototype addition, inverse kinematic equations are formed Matlab/Simulink software order to check accura...

in this study, dynamic behavior of a controller's self destruction mechanism has been simulated using 3d-fem in adams software and investigated. this paper has been concentrated on high acceleration controller's projectiles. this controller is mechanical and has been placed in top of the projectile. the goal of this study is to investigate the destruction mechanism operation i.e. movement of pi...

This paper is concerned with the identification problem of two degree of freedom robot arm’s joints’ time-varying stiffness under time-varying torque loads. The industrial robot arms can be simplified into series hinged linkage mechanism. The unrestraint dynamic equation of two degrees of freedom robot arm can be obtained by using analytical mechanics method. The model which was established in ...
