Cloud-based interactive susceptibility modeling of gully erosion in Google Earth Engine

2022

The gully erosion susceptibility literature is largely dominated by contributions focused on model comparison. This has led to prioritize certain aspects and leave others underdeveloped as compared to other natural hazard applications. For instance, in gully erosion data-driven modeling most studies use different platforms when it comes to data management, modeling and conversion into predictive maps. This in turn has limited the scope to catchment-scales. In this manuscript, we opt to propose a tool where the whole modeling procedure is unified within the same cloud computing system, allowing one to get rid of potential errors caused by input/output operations but also to extend the study …

The Start of a Journey to the Cloud in the Developing World: A Case Study of Egypt

2015

Cloud computing (CC) is becoming a global market trend that all businesses, sooner or later, will go for. Moving to the cloud is a long journey for developing countries that became aware of its importance to their economic development. Egypt started this journey with collective efforts from all stakeholders (i.e., Government institutes, national and international cloud providers, private businesses, and training institutes) to draw the roadmap for CC adoption in Egypt. CC adoption in Egypt is influenced by some enabling and inhibiting factors. These factors are explored by conducting an exploratory case study. The findings of this study are analyzed by utilizing concepts from the neo-instit…

Digital Platforms for Restructuring the Public Sector

2018

Many technological innovations have led to the emergence of the platform economy in recent years. This development is changing the entire landscape of business in the era of digitalisation. However, the impacts of the platform economy on public services and government are not well known. In this article we study the potential for the digital platform economy to help restructure the public sector. Firstly, central features of the new platform technology are explored, pointing to an algorithmic revolution, big data and cloud computing. Platforms are used in coordinating market transactions in an extremely efficient way. In order to apply the platform concept to the public sector, an experimen…

Achieving Intelligent Traffic-aware Consolidation of Virtual Machines in a Data Center Using Learning Automata

2016

Cloud Computing (CC) is becoming increasingly pertinent and popular. A natural consequence of this is that many modern-day data centers experience very high internal traffic within the data centers themselves. The VMs with high mutual traffic often end up being far apart in the data center network, forcing them to communicate over unnecessarily long distances. The consequent traffic bottlenecks negatively affect both the performance of the application and the network in its entirety, posing nontrivial challenges for the administrators of these cloudbased data centers. The problem can, quite naturally, be compartmentalized into two phases which follow each other. First of all, the VMs are co…

ATLAS operations in the GridKa T1/T2 Cloud

2011

The ATLAS GridKa cloud consists of the GridKa Tier1 centre and 12 Tier2 sites from five countries associated to it. Over the last years a well defined and tested operation model evolved. Several core cloud services need to be operated and closely monitored: distributed data management, involving data replication, deletion and consistency checks; support for ATLAS production activities, which includes Monte Carlo simulation, reprocessing and pilot factory operation; continuous checks of data availability and performance for user analysis; software installation and database setup. Of crucial importance is good communication between sites, operations team and ATLAS as well as efficient cloud l…

A Morphological Clustering Method for daily solar radiation curves

2011

Abstract We present a new method based on Mathematical Morphology techniques for the classification of solar radiation curves that we call MfCM. The main advantage of using MfCM as opposed to daily clearness index distributions is that it allows us to keep the dynamics of the solar radiance curves in the analysis: both cloud transitions and variability in direct radiation are simultaneously taken into account. To illustrate our proposal, we use a set of real radiation data collected in a location sited in southern Spain.

Ethical Issues Invoked by Industry 4.0

2021

Industry 4.0 is universally referred to as the fourth industrial revolution. It is a current trend of automation and data exchange in manufacturing technologies. The computerisation of manufacturing includes, amongst other, cyber-physical systems, the Internet of Things (IoT), cloud computing and cognitive computing. There are many challenges in the realisation of Industry 4.0. In order to adopt a “smart factory” and improved (software) processes many ethical considerations need to be identified and considered if a company is to obtain an ethical development and deployment of Industry 4.0. The purpose of normative ethics is to scrutinise standards about the rightness and wrongness of action…

MODIS-Based Monthly LST Products over Amazonia under Different Cloud Mask Schemes

2016

One of the major problems in the monitoring of tropical rainforests using satellite imagery is their persistent cloud coverage. The use of daily observations derived from high temporal resolution sensors, such as Moderate Resolution Imaging Spectroradiometer (MODIS), could potentially help to mitigate this issue, increasing the number of clear-sky observations. However, the cloud contamination effect should be removed from these results in order to provide a reliable description of these forests. In this study the available MODIS Land Surface Temperature (LST) products have been reprocessed over the Amazon Basin (10 N–20 S, 80 W–45 W) by introducing different cloud masking schemes. The mont…

Ontology-based annotation and retrieval of services in the cloud

2014

Cloud computing is a technological paradigm that permits computing services to be offered over the Internet. This new service model is closely related to previous well-known distributed computing initiatives such as Web services and grid computing. In the current socio-economic climate, the affordability of cloud computing has made it one of the most popular recent innovations. This has led to the availability of more and more cloud services, as a consequence of which it is becoming increasingly difficult for service consumers to find and access those cloud services that fulfil their requirements. In this paper, we present a semantically-enhanced platform that will assist in the process of …
