M-generalised q-neutrosophic extension of CoCoSo method
Full text linkNowadays fuzzy approaches gain popularity to model multi-criteria decision making (MCDM) problems emerging in real-life applications. Modern modelling trends in this field include evaluation of the criteria information uncertainty and vagueness. Traditional neutrosophic sets are considered as the effective tool to express uncertainty of the information. However, in some cases, it cannot cover all recently proposed cases of the fuzzy sets. The m-generalized q-neutrosophic sets (mGqNNs) can effectively deal with this situation. The novel MCDM methodology CoCoSomGqNN is presented in this paper. An illustrative example presents the analysis of the effectiveness of different retrofit strategy selection decisions for the application in the civil engineering industry
Optimization of Road Traffic Using Intelligent Traffic Light Systems
Full text linkIf we consider road traffic in urban areas, one of its major problems encountered nowadays is that of traffic congestion. The paper aims to provide an improvement, in terms of reducing traffic congestion, by analyzing different traffic light cycles. A traffic light cycle is determined by the red and green duration of the traffic lights. Traditionally these two have a fixed duration and controlling road traffic can be achieved by modifying it, resulting in a congestion reduction. We present a comparison between the fixed and an improved fixed situation, as well as a QL algorithm to further reduce the congestion at an intersection. Urban traffic can thus be optimized, in terms of reducing congestion, on an existing traffic light system. A study case validates the results, based on road traffic data obtained from the city of Bucharest
The effects of foreign direct investment on the host country
Full text linkA corresponds to any flow of foreign direct investment (including loans) granted to foreign companies, provided that residents investing country (in general - enterprise) have an important part of this business property. It is distinguished from short baths capital movements. Direct investment involves mobilization of capital transferred abroad. For this reason, the national statistical departments groups, often under the term direct investment, purchases of shares and long-term loans to the same group of companies that contribute to the industrial capital of the lending company, ie its production capacity
HOW WILL THE UNIVERSITY CHANGE WITH THE COVID-19 PANDEMIC? AN ITALIAN PERSPECTIVE
Full text linkThe shock of the closure to contain the Covid-19 pandemic has forced universities all over the world to make rapid changes to their teaching and research; but also changed the social and economic role in the area where the university is located. In fact, after an initial period of disorientation and more than a year of distance learning, the students and teachers began to appreciate the "new university" made up of different times and places; a more inclusive university. It is therefore necessary to emphasise the need to focus all attention on managing this change and designing the future of the university worldwide; a reflection that is part of a broader context of studies, research and reflections undertaken at academic and institutional level to identify the new possible university scenarios in which to invest in order not to find oneself disoriented in a new world made up of different teaching methods, new ways of providing services to students, new relationships between research and teaching and also new administrative processes. These aspects will be the most important part of the orientation of young people and adults in choosing the university where to study
THE HUMAN PERSONS PROTECTED BY MEANS OF THE CIVIL LAW
Full text linkThe ensemble of legal means used for human protection forms the system of means of protecting the natural person. This system has been characterized in the legal literature as a "unity in diversity".- unity, because its purpose is the protection of man;- diversity, because it is made up of legal means of branch protection”, that is to say civil law, commercial law, family law, labor law, constitutional law, financial law, criminal law etc. In the last period the scope of human legal protection was completed by the adoption of normative acts aimed at protecting the natural person. Civil law, like other branches of law, includes numerous institutions and norms that ensure the defense and protection of the subjective rights of natural persons. The norms of the civil law ensure protection by special means to the following categories of persons:- to minors, through parental protection, guardianship and trusteeship;- to the alienated and the mentally instable, by putting under interdiction and establishing the guardianship and the trusteeship;- persons in special situations (old age, illness, physical disability), by establishing the trusteeship
A Unique Multi-Agent-Based Approach for Enhanced QoS Resource Allocation in Multi Cloud Environment while Maintaining Minimized Energy and Maximize Revenue
Full text linkThe use of the multi-cloud data storage in one heterogeneous service is a polynimbus cloud strategy. Cloud computing uses a pay-as-you-go model to deliver services to a variety of end users. Customers can outsource daunting tasks to cloud data centres for processing and producing results, thanks to cloud computing. Cloud computing becomes the popular IT brand that provides various on-demand services over the internet. This technology is devoted to distributing computer and software resources. The proven usefulness of workflows to enforce relevant scientific achievements is the availability of data from advanced scientific tools. Scheduling algorithms are essential in order to automate these strenuous workflows efficiently. A number of new heuristics based on a Cloud resource model have been developed. The majority of these heuristic - based address QoS issues in one or two dimensions. The cloud computing technology offers a decentralised pool of services and resources with various models that are provided to the customers across the Internet in an on-demand, continuously distributed, and pay-per-use model. The key challenge we address in this paper is to maximise revenue while maintaining a minimum consumption of energy with an enhanced QoS for resource allocation. The obtained results from proposed method when compared with the existing state of art methods observed to be novel and better
Performance Improvement of Low-Cost Iterative Learning-Based Fuzzy Control Systems for Tower Crane Systems
Full text linkThis paper is dedicated to the memory of Prof. Ioan Dzitac, one of the fathers of this journal and its founding Editor-in-Chief till 2021. The paper addresses the performance improvement of three Single Input-Single Output (SISO) fuzzy control systems that control separately the positions of interest of tower crane systems, namely the cart position, the arm angular position and the payload position. Three separate low-cost SISO fuzzy controllers are employed in terms of first order discrete-time intelligent Proportional-Integral (PI) controllers with Takagi-Sugeno-Kang Proportional-Derivative (PD) fuzzy terms. Iterative Learning Control (ILC) system structures with PD learning functions are involved in the current iteration SISO ILC structures. Optimization problems are defined in order to tune the parameters of the learning functions. The objective functions are defined as the sums of squared control errors, and they are solved in the iteration domain using the recent metaheuristic Slime Mould Algorithm (SMA). The experimental results prove the performance improvement of the SISO control systems after ten iterations of SMA
Travel preference of bicycle-sharing users: A multi-granularity sequential pattern mining approach
Full text linkPublic bicycles are an indispensable part of green public transportation and are also a convenient and economical manner for the general public. In operation management, it is very important and imperative to understand the user demand and pattern of the public bicycle system. This paper took the public bicycle system in Hohhot as the research object, collected nearly 4 years of operating data, and studied the travel preferences of users in the public bicycle system in view of multiple granularities. Specifically, the data of car rental users at three time-granularities were obtained through data extraction technology. Finally, frequent pattern mining was performed on car rental data based on different time granularities and mapped to the user’s riding preference, and then the riding modes of different car rental users founded on different time granularities were determined. Finally, this article gave different management opinions based on the different riding preferences of public bicycle users in Hohhot
Online Healthcare Privacy Disclosure User Group Profile Modeling Based on Multimodal Fusion
Full text linkWith the spread of COVID-19, online healthcare is rapidly evolving to assist the public with health, reduce exposure and avoid the risk of cross-infection. Online healthcare platform requires more information from patients than offline, and insufficient or incorrect information may delay or even mislead treatment. Therefore, it is valuable to predict users’ privacy disclosure behaviors while fully protecting their information, which can provide healthcare services for users accurately and realize a personalized online healthcare environment. Compared with the traditional static online healthcare platform user privacy disclosure behavior influence factor analysis, this paper uses multimodal fusion and group profile technology to build a user privacy disclosure model and lay the foundation for personalized online healthcare services. This paper proposes a cross-modal fusion modeling approach to address the problem that the information of each modality cannot be fully utilized in the current online healthcare privacy disclosure modeling. A multimodal user profile approach is used to construct personal and group profiles, and the privacy disclosure behavioral characteristics reflected by both are integrated to realize accurate personalized services for online healthcare. The case study shows that compared with the static unimodal privacy disclosure model, the accuracy of our method gains significant improvement, which is helpful for precision healthcare services and online healthcare platform development
THE STATUTE OF THE BRITISH CITIZENS ON THE TERRITORY OF ROMANIA IN THE CONTEXT OF BREXIT - UNION LEGISLATIVE AND TRANSPOSITION MECHANISMS
Full text linkOn February 1, 2020 The Withdrawal Agreement1 between the United Kingdom of Great Britain and Northern Ireland (generic-United Kingdom) and the European Union (EU) and the European Atomic Energy Community (Euratom), hereinafter referred to as the Union, has entered into force). This official document guarantees the two parties a withdrawal in conditions of legal certainty concerning areas such as the rights of British citizens and union nationals, the customs regime, trade and services, the rights of companies, etc. In a first analysis of the effects of Brexit, we mention the acquisition by the United Kingdom of the status of a third party with all the consequences that arise, such as withdrawal from the decision-making process, withdrawal of representatives from the Union institutional level. In order to support British citizens who continue to reside in the territory of the European Union but also to support Union nationals resident in the United Kingdom, in accordance with the Withdrawal Agreement, on the one hand, one continued to apply the European Union law to the United Kingdom on the entire transition period which lasted until 31 December 2020, while EU Member States were required to adopt national legal instruments governing both the transition period and beyond, the status of British citizens called "beneficiaries of Art. 50 TEUs who continued to live and work in the Union territory. Romania has fulfilled this obligation deriving from its status as a member state in the sense that on November 23, 2020, the Romanian executive adopted the Government Emergency Ordinance no. 204 of 23 November 2020 on the establishment of measures for the implementation of the Agreement on the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the European Union and the European Atomic Energy Community, regarding the regulation of the right of entry and residence in Romania
