Visible light communication for smart cities
Get PDFObjectives: This paper presents the results of Hybrid-VLC/IR-RF project that can be applied for secure communication using optical spectrum in smart cities. Experiments using this novel communication system is presented inside buildings and applicability for inter-building smart city applications is evaluated. Prior work: Some previous work has focused on integrating new hardware components specific to the VLC/IR-RF hybrid communications system and a brief description of the architecture of the communications system has been presented in a paper at CYSEC conference. Approach: The paper presents the case study about new ways of implementing the communication interfaces following the improvements that have been made to the VLC/IR-RF laboratory test bench from the hardware and software point of view. Also, performance evaluations in various environmental conditions are presented. Results: The experiments present integration at prototype level as a test bench for the hybrid VLC communications system. As such, sensor configuration is performed on IoT (Internet of Things) devices and a mobile application is developed for receiving data over MQTT (Message Queuing Telemetry Transport) protocol. Implications: The practitioners can use this solution for communication beyond WiFi/5G radio spectrum where secure communication is needed in harsh environments, for example underground metro, electromagnetic shielded, smogged spaces. Value: The paper presents original work for next generation communication solutions beyond existing wireless communications such as 5G. The attention is focused on the intensive testing of the optical communication system within buildings where SMEs operate, as well as on the evaluation of its functionality for smart cities telemetry

Moving Average model, a Nonlinear Autoregressive Neural Network model, a BATS model and Exponential Smoothing on the collected data and compare their accuracy using error term measuring indicators, choosing the model with the lowest Mean Absolute Percentage Error value. Finding the most accurate forecasting model would help improve monetary and fiscal politics, as well as orient future personal investments
Developing the European Villages in the Republic of Moldova taken into account the Digital Economy Society Index (DESI)
Get PDFThe digital competitiveness of regions of EU member states is measured by the Digital Economy and Society Index (DESI), a composite index summarizing the progress made in connectivity, digital skills, internet use by citizens, digital integration of enterprises, farms and digital public services, while at the local government level there is currently no single indicator measured on a regular basis. Based on recent international and national researches, it can be concluded that with the development of digital technology, a significant increase in services and solutions available to citizens digitally is expected. Recent positive experiences of EU member states, which have been analyzed in previous research papers, show that the creation of jobs in agricol sectors in rural areas contributes to increasing household incomes. The objective of our study is to analyze and implement the methods and data sources for calculating DESI indicators at the level of local administrative units in the Republic of Moldova, in the context of the National Program for the European Village, launched in spring 2022. The results of the study will be the development of recommendations for local administrations on the use of the DESI index to coordinate the European evaluation parameters. The value of this work is in reinforcing activities for localisation of smart infrastructure and spatial data taking in consideration the DESI index and innovative products of the national Innovation Centres in innovative economics, stimulating investments in the creation of Smart Villages
Security Testing With Python Scripts
Get PDFCyber security is one of the main issues that is discussed today everywhere in the world. The development of technology has grown rapidly and it is important that this development should be done simultaneously with the increase in security. When we talk about the network, we must also consider its "Security". On the other hand, Python is a language which, especially in recent times, has received a great development and now we can say that it enjoys such a wide community. Our goal in this article is the advantages that this programming language offers in cases of cyber security issues. It has everything that cyber security professionals need to protect against cyber vulnerabilities and threats. It allows developers to do anything that relates to cyber security by detecting threats to system fixes. Python is a high-level, general-purpose, interpreted programming language for analyzing small networks. So, the implications of the study are for cybersecurity professionals and developers. They use the NetworkX grid tools imported into python. NetworkX provides many functions and generation facilities to read and write graphics in many formats. By analyzing these network nodes graphs, are identified the nodes that can be "bad". With Python scripts, you can scan ports and compromised device. In order to achieve this, we have obtained two concrete dataset which were obtained respectively from a public and a private network. After analyzing the graphs, the weaknesses of the network and unidentified devices in the network are identified, creating the possibility of taking appropriate measures to protect against cyber-attacks

Protectia si securitatea informatiilor la nivelul autoritatilor publice nationale din Romania
Get PDFSpatiul cibernetic se caracterizeaza prin anonimat, dinamism si lipsa frontierelor. Acest lucru genereaza atat oportunitati de dezvoltare a societatii informationale, cat si riscuri la adresa functionarii acesteia la nivel individual, statal si interstatal. Asigurarea securitatii spatiului informatic devine o preocupare majora a tuturor actorilor implicati, mai ales la nivel institutional, unde se concentreaza responsabilitatea elaborarii si aplicarii de politici coerente in domeniu, fapt care prevede necesitatea dezvoltarii culturii de securitate cibernetica a utilizatorilor sistemelor informatice si de comunicatii, utilizatori adesea insuficient informati in legatura cu potentialele riscuri, dar si cu solutiile de contracarare a acestora. In consecinta, una din premisele dezvoltarii unei societati sigure, sanatoase si puternice in Romania este reprezentata de prevenirea si combaterea riscurilor si amenintarilor la adresa securitatii cibernetice a tarii
Oferta nonpietei – evitarea modelului creeaza doar unul diferit
Get PDFLucrarea analizeaza elementele necesare fazei initiale a managementului adaptiv (stabilirea decidentilor, obiectivelor, alternativelor, modelelor predictive si monitorizarii), prin revizuirea unor modele decizionale. Cele opt modele selectionate sunt revizuite intr-un table sinoptic, urmarindu-se patru aspect: “Unde se aplica modelul?” (I1), “Se poate aplica in sistemul public?” (I2), “Ce este specific, particular?”(I3), “Care este numarul de factori implicati in procesul decizional?”(I4). Asadar, prima parte isi propune sa faca o introducere in problematica deciziei, a procesului decizional, dar si a conceptelor, notiunilor si teoriilor specifice. Aceasta initiere urmareste facilitarea intelegerii aspectelor de modelare decizionala, etapa urmatoare dezvoltata in cadrul celei de-a doua parti. Lucrarea este parte a unui proiect post-doctoral care are ca scop revizuirea cercetarii din domeniul politicilor economice referitoare la interventiile in pietele ineficiente, alegerea actiunilor alternative ale institutiilor atat la nivel regional cat si central sau local. Esecul pietei particularizeaza aceasta cercetare, datorita rolului sau in contextul crizei economice actuale si a efectelor acesteia
Concepte esentiale ale managementului strategic in sectorul public
Get PDFAdministratia publica a fost prea putin preocupata de aspectele strategice ale activitatii sale; tratarea cetateanului ca subiect al administrarii s-a incadrat intr-o viziune mai larga ce percepea rolul serviciului public ca o aplicare mecanica a ordinelor politicienilor ce erau singurii abilitati sa dezvolte politici si strategii.Stabilirea unor obiective si scopuri clare reprezinta un proces extrem de dificil in cazul sectorului public iar in acest context construirea unor strategii poate parea un efort lipsit de orice finalitate; totusi, dezbaterea referitoare la imprecizia obiectivelor este mult mai complexa si poate fi extinsa si la sectorul privat, in cazul caruia unii autori argumenteaza ca obiectivul principal traditional referitor la profit poate fi inlocuit din locul central pe care il ocupa cu obiective de tipul responsabilitatii fata de actionari, supravietuirea pe termen lung, realizarea unui consens negociat intre participanti. Configurarea functiilor manageriale, intr-o acceptiune strategica, in sectorul public, se dovedeste un proces complex care implica numerosi actori si necesita armonizarea unor prioritati asimetrice care trebuie sa fie sustinute intr-un climat de colaborare in care consensul este necesar dar foarte greu de obtinut
Consideratii referitoare la modelarea institutiilor administrative si instantelor in perspectiva informatizarii fluxurilor de prelucrare
Get PDFActivitatile administratiei publice si ale instantelor de judecata prezinta caracterele de prelucrare si decizie proprii procesarii in flux a informatiei. Domeniile de activitate implicate in procesele asociate fluxurilor sunt diverse: juridic, al administratiei, al conducerii, economic etc. Fiecare domeniu are sistem stiintific propriu, caracterizat printre altele, printr-un limbaj profesional specific si printr-o logica particulara. Semnificatiile enunturilor formulate in astfel de limbaje sunt in masuri variabile apropiate de semnificatiile acelorasi enunturi in limba literara. Similar,trasaturile fundamentale ale logicilor particulare difera mai mult sau mai putin de logica matematica, logica care este proprie sistemelor de calcul si implicit informatizarii. In plus, sistemele institutionale (complexe de resurse umane, mijloace tehnice, norme, know- how si resurse software) au concomitent comportamente neg-entropice si entropice. Modelul propus in baza consideratiilor anterioare, configurat in vederea informatizarii, evidentiaza perspectivele si limitele produselor software specifice
Crearea schimbarii sociale prin administratia publica inovativa.
Get PDFIn societatea de astazi, bazata pe cunoastere, limitarile nu sunt legate de nivelul tehnologic, ci de gradul de implicare creativa in gasirea de solutii inovative, de noi instrumente de evaluare, decizie, proiectare si implementare strategica. Cunoasterea presupune si actiune iar actiunea competitiva si sustenabila inseamna o gandire anticipativa, o viziune social-antreprenoriala din partea administratiei publice, pentru realizarea unui salt de bunastare sustenabila. Scopul lucrarii este acela de a evidentia importanta inovatiilor intreprinse de administratia publica in crearea schimbarii sociale. Obiectivele cercetarii constau in analizarea legaturii dintre cele doua concepte centrale ale lucrarii, inovatia si schimbarea sociala durabila, aplicarea acestora in cadrul stiintelor administrative si promovarea initiativelor inovative pentru schimbarea nivelului de trai al cetatenilor. Imbunatatirea serviciilor publice se datoreaza inovarii si presupune adaptarea administratiei publice la cerintele si nevoile oamenilor. Strategia Europa 2020 pune accentul pe rolul inovatiei in cadrul societatii inteligente, sustenabile si incluzive ceea ce solicita guvernelor nationale si administratiei publice oferirea unor raspunsuri la provocarile complexe sociale si societale. Lucrarea se bazeaza pe cercetarea literaturii de specialitate, a studiilor privind modul in care sunt aplicate aceste concepte in cadrul altor state cat si utilizarea si analizarea datelor obtinute. Ultima parte a lucrarii este sustinuta de un studiu de caz ce analizeaza modul in care Primaria Municipiului Brasov raspunde provocarilor complexe si gestioneaza serviciile publice. Rezultatele cercetarii constau in impactul social si economic pe care l-au avut actiunile intreprinse de aceasta administratie publica locala din Judetul Brasov asupra vietii cetatenilor si schimbarile produse in cadrul orasului. Lucrarea semnaleaza necesitatea unui demers intens si constant de inovare in activitatile institutiilor publice, fiind necesar implicarea cercetatorilor si practicienilor in realizarea schimbarii sociale. Aceasta cercetare contribuie la cunoasterea mai aprofundata a unor concepte si dezvaluie bune practici din cadrul administratiei publice locale
