Abstract: Federated learning (FL), with the aim of training machine learning models using data and computational resources on edge devices without sharing raw local data, is essential for improving agricultural management and smart agriculture. This study is a review of FL applications that address various agricultural problems. We compare the types of data partitioning and types of FL (horizontal partitioning and horizontal FL, vertical partitioning and vertical FL, and hybrid partitioning and transfer FL), architectures (centralized and decentralized), levels of federation (cross-device and cross-silo), and the use of aggregation algorithms in different reviewed approaches and applications of FL in agriculture. We also briefly review how the communication challenge is solved by different approaches. This work is useful for gaining an overview of the FL techniques used in agriculture and the progress made in this field.

Abstract: Blockchain technology is increasingly being considered among both private enterprises and public services. However, it poses a challenge with regard to aligning its identity management scheme with the Public Key Infrastructure and the Qualified Digital Certificates issued by Qualified Trust Service Providers. To solve this challenge, we will present a solution in the form of an architecture reference model, which enables enterprises and public services to leverage blockchain technology by integrating Qualified Electronic Signatures with blockchain transactions. The evaluation of the architecture reference model is provided through the design of a Blockchain-based Trusted Public Service and a use-case scenario example. The proposed architecture reference model is based on the CEF building blocks EBSI, eSignature, and eID compliant with eIDAS

Abstract: The masters’ thesis aims to examine the practice of appropriation of inherent qualities of certain sites in the city and the necessity of their preservation against dramatically developing trend of private real-estate and consumer-capitalism driven land-claim. The latter, in combination with inadequate response from government institutions can contribute to a total loss of areas of public interest in the city. The location of the former ”Kasarna Morača” military barracks in Podgorica makes for a valuable target for the greedy investors, but also to the public, which could benefit from a large mass of greenery in the very centre of the capital next to the Morača river. For this reason, questions have been raised sparking public debates on how this location, currently an asset of the state, ought to be managed. This project aims to develop an urban regeneration solution for the brownfield area by means of two interconnected segments. The first one is the recreation area along the Morača riverbank which incorporates a large part of the existing greenery and extends to the Mausoleum of the Partisan fighter on the Gorica hill. The second is situated at the Eastern edge of the site. With the adaptive reuse of the existing barrack structures and a new adaptable and flexible structural system, it proposes a set of public and cultural programs along the”Vaka Đurovića” boulevard. Both the green belt and the cultural complex are connected via pedestrian and cycling paths which also lead to a proposed pedestrian bridge connecting the public institutions, neighbourhoods and recreational areas along Morača riverbanks.

Abstract: This document has been developed by the Interoperability Task Force of the EOSC Executive Board FAIR Working Group, with participation from the Architecture WG. Achieving interoperability within EOSC is essential in order for the federation of services that will compose EOSC to provide added value for service users. In the context of the FAIR principles, interoperability is discussed in relation to the fact that “research data usually need to be integrated with other data; in addition, the data need to interoperate with applications or workflows for analysis, storage, and processing”. Our view on interoperability does not only consider data but also the many other research artefacts that may be used in the context of research activity, such as software code, scientific workflows, laboratory protocols, open hardware designs, etc. It also considers the need to make services and e-infrastructures as interoperable as possible. This document identifies the general principles that should drive the creation of the EOSC Interoperability Framework (EOSC IF), and organises them into the four layers that are commonly considered in other interoperability frameworks (e.g., the European Interoperability Framework - EIF): technical, semantic, organisational and legal interoperability. For each of these layers, a catalogue of problems and needs, as well as challenges and high-level recommendations have been proposed, which should be considered in the further development and implementation of the EOSC IF components. Such requirements and recommendations have been developed after an extensive review of related literature as well as by running interviews with stakeholders from ERICs (European Research Infrastructure Consortia), ESFRI (European Strategy Forum on Research Infrastructures) projects, service providers and research communities. Some examples of such requirements are: “every semantic artefact that is being maintained in EOSC must have sufficient associated documentation, with clear examples of usage and conceptual diagrams”, or “Coarse-grained and fine-grained dataset (and other research object) search tools need to be made available”, etc. The document finally contains a proposal for the management of FAIR Digital Objects in the context of EOSC and a reference architecture for the EOSC Interoperability Framework that is inspired by and extends the European Interoperability Reference Architecture (EIRA), identifying the main building blocks required.

Abstract: The Master’s thesis deals with the valorization and restoration of Godinje, the first village in Montenegro with the status of immovable cultural property. The project encompasses an analysis of the present state of the cultural heritage, research of traditional architectural elements of the crmnica house, as well as the role of man in space. An important factor in the development and preservation of architecture is the awareness of space and the factors that define it. With the aim of encouraging the proper maintenance of cultural heritage, while giving purpose to certain objects, the village planning has been resolved. By emphasizing the spatial principles and traditional techniques of construction, and thus the education thereof, the value is emphasized and further development of Godinje is made possible.
Keywords: Godinje, crmnica house, spatial principles, nature and man, culture, language of architecture, cultural heritage, valorization
