Input Shaping/Time Delay Prefilter are techniques for robust vibration control of slewing flexible structures. These are open-loop schemes and cannot handle uncertain initial conditions and effects of disturbances. In this paper, we develop a technique for the design of closed loop input shapers and illustrate it on a simple benchmark problem. Range of uncertainties over which the system remain...

In chaos-based digital communication systems, a correlator is normally used in the coherent detection of the signal. In this paper, an optimum design for such correlatortype receivers is presented. A chaos-based digital communication system with one chaos generator has been used to exemplify the performance of the design. The design can be extended to systems with multiple generators, where the...

While the subject of SMP locking primitives has been well covered in the literature [Val][Schm][Bald][Leh], there has been relatively little discussion on the rationale and process behind the application of these locking primitives. This leads to an inverted problem where the bulk of the work in making a kernel SMP-safe lies above the locking primitives, yet there is little guidance on how and ...

With the ARPS (Advanced Regional Prediction System) Data Analysis System (ADAS) and its complex cloud analysis scheme, the reflectivity data from a Chinese CINRAD-SA Doppler radar are used to analyze 3D cloud and hydrometeor fields and in-cloud temperature and moisture. Forecast experiments starting from such initial conditions are performed for a northern China heavy rainfall event to examine ...

In this correspondence, a finite-horizon discrete H1 filter design with a linear quadratic (LQ) game approach is presented. The exogenous inputs composed of the “hostile” noise signals and system initial condition are assumed to be finite energy signals with unknown statistics. The design criterion is to minimize the worst possible amplification of the estimation error signals in terms of the e...

Spherical t-designs provide quadrature rules for the sphere which are exact for polynomials up to degree t. In this paper, we propose a computational algorithm based on interval arithmetic which, for given t, upon successful completion will have proved the existence of a tdesign with (t + 1)2 nodes and will have computed narrow interval enclosures which are known to contain these nodes with mat...

We study the impact of the QCD DGLAP evolution on the geometric scaling of the gluon distributions which is expected to hold at small x within the saturation models. To this aim we solve the DGLAP evolution equations with the initial conditions provided along the critical line Q2 = Qs(x) with Q 2 s(x) ∼ x and satisfying geometric scaling. Both fixed and running coupling cases are studied. We sh...

Inverse analysis is a method for determining material parameters by minimizing the difference between experimental and the finite element (FE) simulated results, such as the load-stroke curve and barreling shape of a deformed specimen using an optimum design technique. In this study, ring compression tests were conducted to predict the flow stress of materials and interfacial friction condition...

A novel real-time final product quality control strategy for batch operations is presented. Quality control is achieved by periodically predicting the final product quality and adjusting process variables at prespecified decision points. This data-driven methodology employs multiple models, one for each decision point, to capture the time-varying relationships. Thesemodels combine real-time bat...
