    Grid Computing and Cloud Computing are two different technologies that have emerged to validate the long-held dream of computing as utilities which led to an important revolution in IT industry. These technologies came with several challenges in terms of middleware, programming model, resources management and business models. These challenges are seriously considered by Distributed System research. Resources allocation is a key challenge in both technologies as it causes the possible resource wastage and service degradation. This paper is addressing a comprehensive study of the resources allocation processes in both technologies. It provides the researchers with an in-depth understanding of all resources allocation related aspects and associative challenges, including: load balancing, performance, energy consumption, scheduling algorithms, resources consolidation and migration. The comparison also contributes an informal definition of the Cloud resource allocation process. Resources in the Cloud are being shared by all users in a time and space sharing manner, in contrast to dedicated resources that governed by a queuing system in Grid resource management. Cloud Resource allocation suffers from extra challenges abbreviated by achieving good load balancing and making right consolidation decision

    This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

    The purpose of the study was to reveal the directions, challenges and opportunities that arise in the accounting system in the conditions of Industry 4.0, when innovative solutions based on the capabilities of new digital technologies become the management of in-demand enterprises. The role of Industry 4.0 is shown, the features of modern Industry 4 technologies are revealed, the main technologies and production processes are demonstrated, interconnected using industrial protocols to create intelligent data. The rating of digital competitiveness and their readiness to implement Industry 4.0 technologies for 64 countries of the world is given and analyzed. These factors hinder the process of digitalization in countries with a low rating. The influence of Industry 4.0 on the accounting system is determined and the technologies affected by the fourth industrial revolution in terms of accounting (Big Data or Data Analytics, Cloud Computing, AI, Blockchain, Internet of Things (IoT), Robotic Process Automation) and changes waiting for the profession of accountant. The coordination of efforts of business, education and the state in the context of the development of Industry 4.0 technologies was noted
