Forest modeling applications that cover large geographic areas can benefit from the use of widely-held knowledge about relationships between forest attributes and topographic variables. A noteworthy example involves the coupling of field survey data from the Forest Inventory Analysis (FIA) program of USDA Forest Service with digital elevation model (DEM) data in attempts to explain how topograp...

the effect of ph, different concentration of tween 80 and calcium ion on the stability of limonene-in-water emulsions stabilized by various concentration of sodium caseinate (2, 5 and 10%) was evaluated. to this end, emulsions were prepared by ultrasound and their quality attributes including size distribution, mean diameter of droplets, specific surface area and span number were studied as a r...

A growing stream of study stresses the relevance subjective elements in understanding hierarchy preferences that underpin individual travel behavior. The purpose this is to evaluate impact various factors on mode choice. To achieve this, a multinomial logit model (MNL) was used analyze relationships between choice and three classes attributes; Combined Active Latent, only Latent attributes. dat...

BACKGROUND Discrete choice experiments (DCEs) are attribute-driven experimental techniques used to elicit stakeholders' preferences to support the design and implementation of policy interventions. The validity of a DCE, therefore, depends on the appropriate specification of the attributes and their levels. There have been recent calls for greater rigor in implementing and reporting on the proc...

Spontaneously retrieving analogies from presented problem data is an important phase of analogical reasoning, influencing many related cognitive processes. Existing models have focused on semantic similarity, but structural similarity is also a necessary requirement of any analogical comparison. We present a new technique for performing structure based analogy retrieval. This is founded upon de...

The definition of usability has evolved over time. Some of the proposed definitions have been general, and apply to all types of interactive systems. Others were tremendously influenced by the experience of those who proposed the definitions and the domain in which they practiced usability. The definitions, in general, seem to agree that the targeted users, the complexity of the task, the type ...

Previous studies suggest that rodent burrows, a proxy for rodent population are important for predicting plague risk areas. However, studies that link landform, surface attributes and rodent burrows in the Western Usambara Mountains in Tanzania are scanty. Therefore, this study was conducted in plague endemic area of the Western Usambara Mountains in northern, Tanzania, to explore the relations...

Geometric attributes such as curvature or surface orientation are additional information of the 3D points obtained after the scanning of an object. In the classic 3D chain, characterized by a sequential structure, these information are determined from the dense point cloud (from a 3D scanner). Then, they are used to reduce the amount of information and allows to obtain a simplified model. In th...

This paper describes a method to compare an original mesh and its simplified representation. Meshes considered here contain geometric features as well as other surface attributes such as material colors, texture, temperature, and radiation, etc. Many simplification algorithms have been presented in literature. In this paper we present a new method to assess mesh simplification algorithm quality...

The presented approach to discretization of functionally defined heterogeneous objects is oriented towards applications associated with numerical simulation procedures, for example, finite element analysis (FEA). Such applications impose specific constraints upon the resulting surface and volume meshes in terms of their topology and metric characteristics, exactness of the geometry approximatio...
