in this study, the substrate diffusion in an immobilized spherical cell-support aggregate is studied and effects of various parameters are investigated on substrates profile. analyses are performed by using of an analytical solution called the least square method (lsm) and results are compared with numerical solution. the effects of effective diffusion coefficient ( d e ), maximum specific grow...

In this paper, Least Square Method (LSM) and Differential Transformation Method (DTM) are used to solve the problem of laminar nanofluid flow in a semi-porous channel in the presence of transverse magnetic field. Due to existence some shortcomings in each method, a novel and efficient method named LS-DTM is introduced which omitted those defects and has an excellent agreement with numerical sol...

Since road signs are officially managed by local government, they are reliable information for drivers. For systematic managing the road sign information, it is necessary to construct road sign database. In this paper, we deals with automatic road direction information extracting algorithm from road sign imagery obtained by MMS (Mobile Mapping System). Our algorithm consists of three phase. In ...

This paper proposes a new method based on improved FastICA (fast independent component analysis)LSM (the least square method), in order to improve the accuracy and speed of harmonic detection in power system. This work ameliorates the traditional FastICA algorithm by defining the initial value of demixing matrix iteration, thus inducing the iteration times and eliminating the problem of higher-...

Automated generation of digital elevation models (DEMs) from high resolution satellite images (HRSIs) has been an active research topic for many years. However, stereo matching of HRSIs, in particular based on image-space search, is still difficult due to occlusions and building facades within them. Object-space matching schemes, proposed to overcome these problem, often are very time consuming...

This paper proposes a method for reconstructing partially damaged faces based on a morphable face model. Faces are modeled by linear combinations of prototypes of shape and texture. With the shape and texture information from an undamaged region only, we can estimate optimal coefficients for linear combinations of prototypes of shape and texture by simple projection for least-square minimizatio...

Aiming at improving the precision of nodes’ localization, this paper analyses the source of the localization error when using the least square algorithm, and proposes the principle to choose the benchmark anchor nodes in reducing the power of equation. Based on this principle, the algorithm choosing the nearest node as the benchmark anchor node in LSM and the algorithm choosing the synthetic ne...

a meshless approach, collocation discrete least square (cdls) method, is extended in this paper, for solvingelasticity problems. in the present cdls method, the problem domain is discretized by distributed field nodes. the fieldnodes are used to construct the trial functions. the moving least-squares interpolant is employed to construct the trialfunctions. some collocation points that are indep...

substrates' concentration profile was studied in a porous matrix containing immobilized amyloglucosidase for glucose production. this analysis was performed by using an analytical method called least square method, and the results were compared with numerical solution. effects of effective diffusivity, michael's constant, maximum reaction rate and initial substrate concentration were studied on...
