The Fibonomial coe¢ cients are known as interesting generalization of binomial coe¢ cients. In this paper, we derive a (k + 1)th recurrence relation and generating matrix for the Fibonomial coe¢ cients, which we call generalized Fibonomial matrix. We …nd a nice relationship between the eigenvalues of the Fibonomial matrix and the generalized right-adjusted Pascal matrix that they have the same ...

We consider the problem of exact controllability of the wave equation with Dirichlet boundary conditions and multiplicative controls. A multiplicative control is a coeffi cient like uy. Exact controllability result is stated and proved for some particular targets.

background: rheumatoid arthritis (ra) is the most prevalent chronic infl ammatory disease of the joints. it is correlated with periodontal disease due to similar factors that exist in both diseases. the present study assessed the relationship of periodontal disease with ra and juvenile idiopathic arthritis (jia). materials and methods: in this case-control study, 30 ra and 30 jia patients along...

Dual-energy X-ray computed tomography (DECT) is a powerful tool for non-destructive evaluation for security. In security applications where DECT is used for scanning checked luggage, many different materials may be scanned in various degrees of clutter and metal objects are common. Conventionally, fi ltered back-projection (FBP) is used for image formation and there is no unifi ed treatment of ...

POST-PROCESSING OF VIDEO Mark A. Robertson and Robert L. Stevenson Department of Electrical Engineering University of Notre Dame Notre Dame, IN 46556 fmrobert2,[email protected] ABSTRACT We propose a method of reducing the computational complexity of iterative video post-processing algorithms that make use of the convex quantization constraint set. Rather than constraining all DCT coe cients in a blo...

The front-end used in many speaker recognition systems extracts, from the input speech signal, a set of coe cients based on a mel-cepstrum technique. This paper addresses the problem of e ciency of melcepstrum coe cients in a speaker recognition system and suggests a technique permitting an appropriate choice of these coe cients. It is shown, by the results obtained, that this technique can sig...

This paper studies inference about the values of the parameters in the threshold model in a generalized method of moments (GMM) framework. First, we establish that the extensively studied least squares method leads to substantially oversized tests and confidence intervals when the coeffi cient change is not large. Second, by re-ordering the data to recast the threshold model as a structural bre...

git = agIit + b ( lnSi,t−1 − lnSj,t−1;,j∈Ii ) gIit + c ( lnSi,t−1 − lnSj,t−1;,j∈Ii )2 gIit + εit (36) In this model, the loading of firm i can depend not only on the industry average gIit, but also on the size of the firm. To make coeffi cients easier to interpret, I recenter by lnSj,t−1, the average log size, so that the mean of the second term is 0. Table VI reports the first stage of a varie...

Advanced numerical simula on models can poten ally help improve guidelines for irriga on and salinity management. Many simula on model parameters have considerable uncertainty, and ideally that uncertainty should be refl ected in model predic ons and recommenda ons. In this work, we inves gate solute transport predica on intervals that can be generated by propaga ng model parameter uncertainty ...
