Optimization of an existing forest road network using Network 2000

open access: yesCroatian Journal of Forest Engineering, 2007
Optimization of forest road network is an important part of logging planning. Matthews (1942) was the first to introduce a method for optimization of road spacing based on minimization of roading and skidding cost.

Artificial neural networks in urology: Update 2000 [PDF]

open access: yesProstate Cancer and Prostatic Diseases, 1999
Artificial neural networks (ANNs) are widely available and have been demonstrated to be superior to standard empirical methods of detecting, staging and monitoring prostate cancer. These algorithms have been statistically validated in diverse, well-characterized patient groups and are now being evaluated for clinical use worldwide.

Detecting CAN Attacks on J1939 and NMEA 2000 Networks

open access: yesIEEE Transactions on Dependable and Secure Computing, 2022
J1939 is a networking layer built on top of the widespread CAN bus used for communication between different subsystems within a vehicle. The J1939 and NMEA 2000 protocols standardize data enrichment for these subsystems, and are used for trucks, weapon systems, naval vessels, and other industrial systems.

Large-Fire Ignitions Are Higher in Protected Areas than Outside Them in West-Central Spain

open access: yesFire, 2023
Managing protected areas requires knowing what factors control fire ignitions and how likely they are compared to non-protected ones. Here, we modelled fire ignition likelihood in west-central Spain as a function of biophysical and anthropogenic ...

Decision making in forest road planning considering both skidding and road costs: a case study in the Hyrcanian Forest in Iran

open access: yesiForest - Biogeosciences and Forestry, 2013
Hyrcanian forest is the only forest designated for commercial timber production in Iran. Ground-based skidding is the most common extraction system used in the forest, though large parts of the forest are still inaccessible due to the low road density (1-

Prawne ograniczenia działalności podejmowanej na wiejskich obszarach Natura 2000 – wybrane aspekty

open access: yesActa Iuris Stetinensis, 2018
The article attempts to approximate the issue of the functioning of rural areas covered by Natura 2000 network. Rural areas are often covered by various forms of nature conservation, including the youngest of them – the Natura 2000 network.

Radiological Explorations of Patients with Upper or Febrile Urinary Tract Infection

open access: yesInfectious Disease Reports
Recent European Association of Urology (EAU) guidelines and a clinical prediction rule developed by Van Nieuwkoop et al. suggest simple criteria for performing radiological imaging for patients with a febrile urinary tract infection (UTI).

Degenerate Fractals: A Formal and Computational Framework for Zero-Dimension Attractors

open access: yesMathematics
This paper analyzes the extreme limit of iterated function systems (IFSs) when the number of contractions drops to one and the resulting attractors reduce to a single point.
