The mathematical approach for proximity analysis for 3D GIS [PDF]

open access: yes, 2008
Next generation of GIS software would highly depend on 3D analysis in solving geographic problems. 3D analysis is a very important component for GIS as it defines as decision making tools for geographic features.

Developing efficient web-based GIS applications [PDF]

open access: yes, 2010
There is an increase in the number of web-based GIS applications over the recent years. This paper describes different mapping technologies, database standards, and web application development standards that are relevant to the development of web-based ...

Group identities on the units of algebraic algebras with applications to restricted enveloping algebras [PDF]

open access: yesJ. Algebra 319 (2008), no. 10, 4008--4017., 2007
An algebra is called a GI-algebra if its group of units satisfies a group identity. We provide positive support for the following two open problems. 1. Does every algebraic GI-algebra satisfy a polynomial identity? 2. Is every algebraically generated GI-algebra locally finite?

Generalized intelligent states and SU(1,1) and SU(2) squeezing [PDF]

open access: yesarXiv, 2000
A sufficient condition for a state |\psi> to minimize the Robertson-Schr\"{o}dinger uncertainty relation for two observables A and B is obtained which for A with no discrete spectrum is also a necessary one. Such states, called generalized intelligent states (GIS), exhibit arbitrarily strong squeezing (after Eberly) of A and B.

An SDI for the GIS-education at the UGent Geography Department [PDF]

open access: yes, 2011
The UGent Geography Department (GD) (ca. 200 students; 10 professors) has been teaching GIS since the mid 90’s. Ever since, GIS has evolved from Geographic Information Systems, to GIScience, to GIServices; implying that a GIS specialist nowadays has to ...

GIS-ILA: The GIS for Italian logistics in Antarctica

open access: yesGeo-spatial Information Science, 2001
A geographic information system (GIS) is a hardware/software tool which is very effective in collecting, storing, searching, handling, and visualizing geographic data together with their descriptive attributes. Such a tool is very helpful to approach a wide range of situations, including many logistic problems.

Stereotactic radiotherapy for metastatic brain tumors: A comparative analysis of dose distributions among VMAT, Helical TomoTherapy, CyberKnife, Gamma Knife, and ZAP‐X

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract This study evaluates various radiotherapy techniques for treating metastatic brain tumor (BT), focusing on non‐coplanar volumetric modulated arc radiotherapy (NC‐VMAT), coplanar VMAT (C‐VMAT), Helical TomoTherapy (HT), CyberKnife (CK), Gamma Knife (GK), and ZAP‐X.

Estimating Biomass of Barley Using Crop Surface Models (CSMs) Derived from UAV-Based RGB Imaging

open access: yesRemote Sensing, 2014
Crop monitoring is important in precision agriculture. Estimating above-ground biomass helps to monitor crop vitality and to predict yield. In this study, we estimated fresh and dry biomass on a summer barley test site with 18 cultivars and two nitrogen
