. Biomassa atau cadangan karbon merupakan salah satu indikator kelestarian tegakan hutan. Kuantitas biomassa yang stabil dan proporsional mengindikasikan hutan berada dalam kondisi baik. Dalam rangka menjaga hutan, pihak-pihak terkait dituntut untuk selalu aktif di pemantauan satunya adalah tegakan. Penelitian ini bertujuan menguji sejumlah metode interpolasi spasial mengestimasi distribusi huj...

Functional linear regression has been widely used to model the relationship between a scalar response and functional predictors. If the original data do not satisfy the linear assumption, an intuitive solution is to perform some transformation such that transformed data will be linearly related. The problem of finding such transformations has been rather neglected in the development of function...

The HCMV IE2 protein promiscuously activates transcription of many viral and cellular genes. IE2 also negatively autoregulates its own expression by binding to a strategically positioned IE2 binding site, called CRS, located immediately downstream of the TATA box of the HCMV major IE promoter. Here we show that IE2 is able to repress transcription driven by a heterologous promoter, RSV LTR. Rep...

Implementing point cloud to grid conversion for digital elevation maps (DEM) presents one with many options for interpolation and we intend to explore algorithms for interpolation during the conversion process with a specific focus on Voronoi natural neighbor interpolation. By partitioning the environment into Voronoi cells and using the information from neighboring cells and their respective g...

The aim of the present paper is to present a numerical algorithm for the time-dependent generalized regularized long wave equation with boundary conditions. We semi-discretize the continuous problem by means of the Crank–Nicolson finite difference method in the temporal direction and exponential B-spline collocation method in the spatial direction. The method is shown to be unconditionally stab...

We propose a new approach for signal reconstruction from non-uniform samples, without any constraint on their locations. We look for a function that minimizes a classical regularized least-squares criterion, but with the additional constraint that the solution lies in a chosen linear shiftinvariant space—typically, a spline space. In comparison with a pure variational treatment involving radial...

This paper proposes a novel approach that achieves shape registration by optimizing shape representation and transformation simultaneously, which are modeled by a constrained Gaussian Mixture Model (GMM) and a regularized thin plate spline respectively. The problem is formulated within a Bayesian framework and solved by an expectation-maximum (EM) algorithm. Compared with the popular methods ba...

This paper presents our numerical results of the application of Isogeometric Analysis (IGA) to the velocity–pressure formulation of the steady state as well as to the unsteady incompressible Navier–Stokes equations. For the approximation of the velocity and pressure fields, LBB compatible B-spline spaces are used which can be regarded as smooth generalizations of Taylor–Hood pairs of finite ele...

The paper considers a numerical method for solving the Fredholm integral equation of first kind. essence is to replace original with corresponding regularized second kind, which then solved by modified spline collocation method. solution in this case represented as linear combination minimal splines. coefficients at splines are computed using local approximation (in some cases, quasi-interpolat...
