Detecting recombination from gene trees [PDF]

open access: yesMolecular Biology and Evolution, 1998
In this article, a method is proposed for detecting recombination in the sequences of a gene from a set of closely related organisms. The method, the Homoplasy Test, is appropriate when the sequences are rather similar, differing by 1%-5% of nucleotides.

Cycle detection in computation tree logic [PDF]

open access: yesInformation and Computation, 2016
Temporal logic is a very powerful formalism deeply investigated and used in formal system design and verification. Its application usually reduces to solving specific decision problems such as model checking and satisfiability. In these kind of problems, the solution often requires detecting some specific properties over cycles.

Reset Tree-Based Optical Fault Detection [PDF]

open access: yesSensors, 2013
In this paper, we present a new reset tree-based scheme to protect cryptographic hardware against optical fault injection attacks. As one of the most powerful invasive attacks on cryptographic hardware, optical fault attacks cause semiconductors to misbehave by injecting high-energy light into a decapped integrated circuit. The contaminated result from

Randomized outlier detection with trees [PDF]

open access: yesInternational Journal of Data Science and Analytics, 2020
AbstractIsolation forest (IF) is a popular outlier detection algorithm that isolates outlier observations from regular observations by building multiple random isolation trees. The average number of comparisons required to isolate a given observation can then be used as a measure of its outlierness.

Assessment of Tree Detection Methods in Multispectral Aerial Images

open access: yesRemote Sensing, 2020
Detecting individual trees and quantifying their biomass is crucial for carbon accounting procedures at the stand, landscape, and national levels. A significant challenge for many organizations is the amount of effort necessary to document carbon storage

Robust Tree-Ring Detection [PDF]

open access: yes, 2007
The study of tree-rings is a common task in dendrology. Usually the rings deliver information about the age of the tree, historic climate conditions and forest densities. Many different techniques exist to perform the tree-ring detection, but they commonly are semi-automatic.

Computation Tree Logic with Deadlock Detection [PDF]

open access: yesLogical Methods in Computer Science, 2009
We study the equivalence relation on states of labelled transition systems of satisfying the same formulas in Computation Tree Logic without the next state modality (CTL-X). This relation is obtained by De Nicola & Vaandrager by translating labelled transition systems to Kripke structures, while lifting the totality restriction on the latter.

Measurement of Forest Inventory Parameters with Apple iPad Pro and Integrated LiDAR Technology

open access: yesRemote Sensing, 2021
The estimation of single tree and complete stand information is one of the central tasks of forest inventory. In recent years, automatic algorithms have been successfully developed for the detection and measurement of trees with laser scanning technology.

Online Anomaly Detection With Nested Trees [PDF]

open access: yesIEEE Signal Processing Letters, 2016
We introduce an online anomaly detection algorithm that processes data in a sequential manner. At each time, the algorithm makes a new observation, produces a decision, and then adaptively updates all its parameters to enhance its performance. The algorithm mainly works in an unsupervised manner since in most real-life applications labeling the data is

Large-Scale Oil Palm Trees Detection from High-Resolution Remote Sensing Images Using Deep Learning

open access: yesBig Data and Cognitive Computing, 2022
Tree counting is an important plantation practice for biological asset inventories, etc. The application of precision agriculture in counting oil palm trees can be implemented by detecting oil palm trees from aerial imagery.
