livestock grazing and rangelands fire are important ecological disturbances influencing the vegetation and soil properties in rangelands ecosystem. this study was conducted to determine the effects of different burned treatments and distances from the water sources on some soil and vegetation properties of rangelands ecosystem. the experiment was conducted in lashgar dar rangelands. vegetation ...

The paper explores a framework combining remote sensing and spatial metrics aimed at improving the analysis and modeling of urban growth and land use change. While remote sensing data have been used in urban modeling and analysis for some time, the proposed combination of remote sensing and spatial metrics for that purpose is quite novel. Starting with a review of recent developments in each of...

We consider the problem of estimating the parameters of a two-dimensional Ney-man-Scott process, from data collected through a line transect survey. Cowling (1998) suggested an estimation method based on a one-dimensional K-function along the transect line. However, her expression for the theoretical K-function was wrong. We develop the correct K-function. We further carry out a simulation stud...

The overall goal of this project is to improve our understanding of beaked whale distribution and foraging behavior and to describe inter-specific differences. We are developing habitat models for multiple beaked whale species in the Southern California Bight using passive acoustic encounters. Data from line transect surveys and autonomous recorders are compared with dynamic and static oceanogr...

The uncertainty in estimation of spatial animal density from line transect surveys depends on the degree of spatial clustering in the animal population. To quantify the clustering we model line transect data as independent thinnings of spatial shot-noise Cox processes. Likelihood-based inference is implemented using Markov chain Monte Carlo (MCMC) methods to obtain efficient estimates of spatia...

Median sternotomy is frequently selected for the resection of pulmonary artery tumor, and pneumonectomy is performed for complete resection. However, it is difficult to see the inferior pulmonary vein and transect it safely via median sternotomy, so additional thoracotomy is often required and this is highly invasive. In the present case, we employed thoracoscopy (which we routinely use for VAT...

Thirteen repetitions of a cross-channel transect in the Khuran Channel within the Strait of Hormuz allowed the description of the mean flow and semidiurnal tidal properties of a northsouth transect. Water velocity profiles were obtained with a 614.4 kHz TRDI Work Horse Broadband ADCP along this 3.3 km long transect on 10 October 2014, the third day of secondary spring tide. The M2, M4 and M6 fr...
