the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...

Synopsis A computer-based technique has been developed for the determination of specific gravity distribution profiles. It has been designed to overcome many of the practical and technical problems that are often encountered in conventional methods of determining specific gravity profiles, such as heavy-liquid analysis. The new technique relies on a minimum of easily obtainable input data (assa...

In recent years, increasing attention has been paid to household impoverishment in Italy. Most of works dealing with this issue are based on summary statistics, which do not capture the whole information contained in the income distribution. The paper applies a non-parametric tool, the “relative distribution”, to Italian household income data during 2002-2004. The relative density function is a...

BACKGROUND This study compares the efficiency of identifying the plants in an area of semi-arid Northeast Brazil by methods that a) access the local knowledge used in ethnobotanical studies using semi-structured interviews conducted within the entire community, an inventory interview conducted with two participants using the previously collected vegetation inventory, and a participatory worksho...

A preliminary study of the mechanical properties of auxetic cellular material consisting of re-entrant hexagonal honeycombs is presented. For different scales of the honeycombs, the finite element method (FEM) and experimental models are used to perform a parametric analysis on the effects of the Poisson's ratio (cell angle) and the relative density (cell thickness) of honeycombs on bearing cap...

[1] This study deals with deformation of small pores in wet soils of relatively high bulk density such as in the final settlement phase of tilled or disturbed soils. Pore deformation was modeled by volume reduction of spherical voids embedded in a homogenous soil matrix. External constant stress and overburden were considered as steady stresses because the change in interaggregate contact stres...

Detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. This distribution could be detected by different geophysical methods, especially gravity method. However, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. Performance of the gravity technique co...

aim and background: psychotic patients are at the risk of hyponatremia due to numerous reasons .given that severe hyponatremia can cause serious risks including seizures, coma and death, taking the symptoms into account seems necessary when patients referring to medical centers. therefore, the present study aimed to determine the prevalence rate of hyponatremia in psychotic patients in farshchi...

Density of aggregate is the ratio between solid mass and water with same volume at temperature, while absorption ability to absorb in dry surface saturation conditions (SSD). This what motivates authors compare conclude value specific gravity fine aggregates obtained standard. In this study, discussed investigation density & for properly correctly compared values ​​of Based on specification...

we inverse the surface gravity data to recover subsurface 3d density distribution with two strategy. in the first strategy, we assumed wide density model bound for inverting gravity data and in the second strategy, the inversion procedure have been carried out by limited bound density. wediscretize the earth model into rectangular cells of constant andunidentified density. the number of cells i...
