In this paper, approximate analytical solution of SIRC model associated with the evolution of influenza A disease in human population is acquired by the modified differential transform method (MDTM). The differential transform method (DTM) is mentioned in summary. MDTM can be obtained from DTM applied to Laplace, inverse Laplace transform and padé approximant. The MDTM is used to increase the a...

It is the aim of this paper to investigate a suitable approach to compute solutions of the powerful Michaelis-Menten enzyme reaction equation with less computational effort. We obtain analytical-numerical solutions using piecewise finite series by means of the differential transformation method, DTM. In addition, we compute a global analytical solution by a modal series expansion. The Michaelis...

In this paper, an aproximate analytical method called the differential transform method (DTM) is used as a tool to give approximate solutions of nonlinear oscillators with fractional nonlinearites. The differential transformation method is described in a nuthsell. DTM can simply be applied to linear or nonlinear problems and reduces the required computational effort. The proposed scheme is base...

Accurate terrain models are a crucial component of studies of river channel evolution. In this paper we describe a new methodology for creating high-resolution seamless digital terrain models (DTM) of river channels and their floodplains. We combine mobile laser scanning and low-altitude unmanned aerial vehicle (UAV) photography-based methods for creating both a digital bathymetric model of the...

The Rochem Separation Systems, Inc. (Rochem) Disc TubeTM Module (DTM) technology is an innovative membrane separation process. It is designed to treat liquid waste that is higher in dissolved solids content, turbidity, and contaminant levels than waste treated by conventional membrane separation processes. According to the technology developer, Rochem, the innovative DTM design reduces the pote...

In chemical engineering, several processes are represented by singular boundary value problems. In general, classical numerical methods fail to produce good approximations for the singular boundary value problems. In this paper, Chebyshev finite difference (ChFD) method and DTM-Pad´e method, which is a combination of differential transform method (DTM) and Pad´e approximant, are applied for sol...

This paper describes an algorithm which aims at deriving digital terrain models (DTM) from dense digital elevation models (DEM). This algorithm takes place in a processing chain for building detection and modelling in urban areas from high resolution aerial imagery. DEM either come from stereophotogrammetry, or from direct measures such as airborne laser data. DTM are computed as low order freq...

This paper presents the DTM accuracy derived from JERS-1 SAR Interferometry based on the branch cut method. The target area were selected FUJI and FUGEN mountain in the volcanic mountaions. The accuracy of the calculated DTM is that maximum error and R.M.S.E were 217m, and 27.7m respectively. The accuracy weren’t better than theoretical values, but it is regarded as the next factor. (1) satelli...

Introduction: Pyrethroids are important insecticides because of their high activity and low mammalian toxicity. Some studies have demonstrated that these insecticides, especially compounds with an -cyano group, produce toxic effects on various biological systems. Deltamethrin (DTM) is a Type II synthetic pyrethroid insecticide containing -cyano group and is used worldwide in agriculture, ho...

Nowadays, DTM databases are vital for a variety of applications, such as visualization or terrain analysis. Therefore, in the fields of civil engineering, mapping and geo-information, or geophysics, this data is on the functional route leading from data acquisition to derived applications. One of the main issues when dealing with DTM database representation is data merging, which involves the i...
