The presented approach attempts to highlight the capabilities of a data fusion approach that combines UAV LiDAR (RIEGL – miniVUX-1UAV) and multispectral data (Micasense – Altum) to assess the dry above ground biomass (AGB) for maize. The combined acquisition of both LiDAR and multispectral data not only supports estimates of AGB when fusing them, but also helps to evaluate phenological stage-specific modelling differences on the individual sensor data. A multiple linear regression was applied on the multisensorial UAV data from two appointments in 2021. The resulting R2 of 0.87 and RMSE of 14.35 g/plant for AGB was then transferred to AGB in dt/ha. © 2023 Gesellschaft fur Informatik (GI). All rights reserved.

We present a prototype-based machine learning analysis of labeled galaxy catalogue data containing parameters from the Galaxy and Mass Assembly (GAMA) survey. Using both an unsupervised and supervised method, the Self-Organizing Map and Generalized Relevance Matrix Learning Vector Quantization, we find that the data does not fully support the popular visual-inspection-based galaxy classification scheme employed to categorize the galaxies. In particular, only one class, the Little Blue Spheroids, is consistently separable from the other classes. In a proof-of-concept experiment, we present the galaxy parameters that are most discriminative for this class. © ESANN 2018 - Proceedings, European Symposium on Artificial Neural Networks, Computational Intelligence and Machine Learning.

SpectroML is a markup language for molecular spectrometry data that can be used as a "web-aware" mechanism for inst.ument-to-inst.ument, inst.ument-to-application, and application-to-application data interchange and archiving. SpectroML was developed using XML (extensible mark up language), and its vocabulary was gleaned from the terminology, data dictionaries, and concepts embodied in existing standards, inst.ument software, and data interchange formats. Currently, we have created a SpectroML vocabulary, document type definition, schema, stylesheets, and some demonstration applications for UV-visible spectroscopy data;however, the structure and flexible data model embodied in SpectroML should make it easily adaptable to other spectroscopy techniques.

An intrusion detection system aims to identify unauthorized accesses to computer systems' resources and data. A number of detection models have been proposed based on neural networks. In this research, we propose the use of Singular Value Decomposition as a preprocessing step to improve the performance of neural network models and provide the results from our preliminary analysis of this approach.

This paper explores the utilization of adaptive triangular meshes representing gray-level images to accelerate basic image processing operations. In particular, two algorithms for thresholding and labeling gray-level images represented with adaptive triangular meshes are described and evaluated. Experimental results with real gray-level images show that it is possible to perform faster by working in the 3D geometric domain than by sequentially processing all the pixels contained in the original images. © 2000 IEEE.

The TRMM standard PR-2A25 products generated and provided by NASA and NASDA were used to analyze the characteristics of typhoon's rainfalll on ground surface of Taiwan. The rain gauge data were used to validate the rainfall rate rerieved by PR. Also the relationship between rain gauge and PR_RR was established. The PR-PR is underestimated approximately by 31% compared with RG_RR for typhoon NARI case, and 62% for Typhoon RAMMASUN case.

Heterogeneous multiserver queues with general input

A queueing system with heterogeneous servers and general input is analyzed. In particular, it is shown how to obtain the steady state probabilities for such a system, both at random-times and at the times preceding an arrival. If more than one server is idle, an arrival has the choice how to select one of the idle servers. The rules used to do the selection are part of the model description. The probabilities at arrival points are found as follows. First, one determines the probabilities for all states in which there is no queue, and then one calculates the probabilities in which customers are waiting. The probabilities at arrival epochs allow one to find the probability of no wait, the waiting time distribution, and the distribution of the number in the system at random epochs. Heuristic arguments, supported by numerical calculations, show that the importance of selecting a server increases with decreasing traffic intensity, increasing number of servers, and decreasing variation between interarrival times.

Underwater Acoustic Networks (UANs) are an emerging technology that are being used to facilitate new aquatic applications in our water world. This is accomplished by linking underwater sensors, vehicles and devices together using acoustic communication. Network protocol development for UANs often relies on simulations because deploying real systems in the ocean is a resource heavy operation. However, acoustic communication performance is dynamic and dependent upon the environment. Therefore, simulations may not be entirely accurate. In this paper we introduce an advanced channel model that considers environmental impacts and real system characteristics on acoustic communication performance for use in an established open-source simulation environment, Aqua-Sim. We provide detailed simulation results and compare the results of our channel model with the existing simulation environment and against.the results from a field experiment in the Chesapeake Bay from 2011. © 2013 MTS.

We propose a new linear array for multiplication in GF(2m) which outperforms most of the existing linear multipliers in terms of the area and time complexity. Moreover we will give a very detailed comparison of our array with other existing architectures for the five binary fields GF(2m), m = 163, 233, 283, 409, 571, recommended by NIST for elliptic curve cryptography. © Springer-Verlag Berlin Heidelberg 2006.
