Collaborative Cloud Computing Application for Water Resources Based on Open Source Software [chapter]

Blagoj Delipetrev, Aleksandra Stojanova, Ana Ljubotenska, Mirjana Kocaleva, Marjan Delipetrev, Vladimir Manevski
2016 Advances in Intelligent Systems and Computing  
The cloud computing application for water resources modeling and optimization based on open source software is a continuation of a previous research presented in [1] . This article presents further research that is focused on distributing the web application on two separate virtual machines (VM) and upgrading it to a cloud computing application. The cloud application was deployed and tested in a distributed computer environment running on two virtual machines (VM-1 and VM-2). The application is

The web services for support of water resources modelling and user management are deployed on VM-1 while the SDI and water resources optimization web services are deployed on VM-2. The web services communicate with web feature service transactional (WFS-T), which is an XML asynchronous messaging protocol. This research demonstrates the capability to scale and distribute the cloud application between several VMs. The article discusses the main cloud application capabilities and its future upgrades.

A novel nested dynamic programming (nDP) algorithm for multipurpose reservoir optimization

Blagoj Delipetrev, Andreja Jonoski, Dimitri P. Solomatine
2015 Journal of Hydroinformatics  
In this paper, we present a novel nested dynamic programming (nDP) algorithm for multipurpose reservoir optimization. The nDP algorithm is built from two algorithms: 1) dynamic programming (DP) and 2) nested optimization algorithm implemented with Simplex and quadratic Knapsack. The novel idea is to include a nested optimization algorithm into the DP transition that lowers the starting problem dimension and alleviates the DP curse of dimensionality. The nDP can solve multi-objective

Computationally, the nDP is very efficient and it can handle dense and irregular variable discretization, it is coded in Java as a prototype application and has been successfully tested with eight objectives at the Knezevo reservoir, located in the Republic of Macedonia.

Evaluation of the Potential of Convolutional Neural Networks and Random Forests for Multi-Class Segmentation of Sentinel-2 Imagery

Vasileios Syrris, Paul Hasenohr, Blagoj Delipetrev, Alexander Kotsev, Pieter Kempeneers, Pierre Soille
2019 Remote Sensing  
Motivated by the increasing availability of open and free Earth observation data through the Copernicus Sentinel missions, this study investigates the capacity of advanced computational models to automatically generate thematic layers, which in turn contribute to and facilitate the creation of land cover products. In concrete terms, we assess the practical and computational aspects of multi-class Sentinel-2 image segmentation based on a convolutional neural network and random forest approaches.
more » ... The annotated learning set derives from data that is made available as result of the implementation of European Union's INSPIRE Directive. Since this network of data sets remains incomplete in regard to some geographic areas, another objective of this work was to provide consistent and reproducible ways for machine-driven mapping of these gaps and a potential update of the existing ones. Finally, the performance analysis identifies the most important hyper-parameters, and provides hints on the models' deployment and their transferability.

Cloud computing is one of the most promising solutions for present and future water related problems. Planning and management of both urban water systems and basinscale water resources systems are increasingly becoming multidisciplinary collaborative tasks that will rely on development of internet based systems based on web services that combine water related data, weather forecasts, climate variations, urbanization, population and economic growth, etc. These heterogeneous data sources

Cloud computing advantages over previous technologies are in the scalable computation power, internet based collaboration platform, transparency in the decision making processes and dissemination of valuable information between stakeholders and general public. The architecture of prototype cloud application for water resources modeling is based on the latest advancement in computer science and technology: Cloud Computing, Service Oriented Architecture and web Geographic Information Systems. The prototype cloud application integrate three web services: (1) web service for managing of geospatial data (2) web service for support of water resources modeling. The components and software packages used in the development of the system are open source. The overall architecture and system components are flexible for adding new or upgrading existing web services. The system is scalable, interoperable and can work in distributed computer environment.

GEOPHYSICAL ASPECTS OF THE GEOTECTONIC PROCESSES IN THE VARDAR ZONE AND THE EASTERN MACEDONIAN ZONE

Blagoj Delipetrev
2011 SGEM2011 11th International Multidisciplinary Scientific GeoConference   unpublished
A b s t r a c t: The paper deals with correlation dependencies of individual parameters of the Earth's crust in relation to the depth of Moho-discontinuity. These model investigations used data about the territory of the Republic of Macedonia. In the models, the territory was divided in three zones based on its neotectonic geologic setting [1]. The analysis carried out for the correlation coefficients for individual zones made possible the separation of zones relative to one another.
