Assuring SME's Sustainable Competitiveness in the Digital Era. A Labour Policy between Minimum Wage Guaranteed and ICT Skill Mismatch
No full textThe aim of this paper is to analyze the real impact of ICT (Information and Communications Technology) skills mismatch on SME’s (small and medium enterprises) sustainable competitiveness in the presence of a guaranteed minimum wage. As part of public policies—the minimum wage needs to maintain a balance between increasing employment and not being a burden for the companies, leading them to bankruptcies, especially in times of disruptive change, in which economies have to be more resilient. The rapid progress in information and communication technologies has dramatically redefined rising unemployment as a result of skills mismatch. This paper aims to understand, on the one hand, whether there is a match between the supply demand of ICT skills, and how increasingly powerful digital technologies affect the skills, jobs, and demand for human labor. On the other hand, it aims to understand whether increasing productivity and a fair minimum wage could be an integrated approach for stimulating SME’s in increasing sustainable competitiveness

Optimal control of a SIR epidemic with ICU constraints and target objectives
No full textThe aim of this paper is to provide a rigorous mathematical analysis of an optimal control problem with SIR dynamics main feature of our study is the presence of state constraints (related to intensive care units ICU capacity) and strict target objectives (related to the immunity threshold). The first class of results provides a comprehensive description of different zones of interest using viability tools. The second achievement is a thorough mathematical analysis of Pontryagin extremals for the aforementioned problem allowing to obtain an explicit closed-loop feedback optimal control. All our theoretical results are numerically illustrated for a further understanding of the geometrical features and scenarios

Model-based Monte Carlo state estimation for condition-based component replacement
No full textThis paper presents a model-based Monte Carlo method, also called particle filtering, for estimating the failure probability of a component subject to degradation. The estimations are embedded within an optimal policy of condition-based component replacement, in which both replacement upon failure and preventive replacement are considered, and the decision variable is the expected cost per unit time. An application is reported with regards to a component subject to fatigue degradation, modeled by the well-known Paris-Erdogan law. The possibility of predicting accurately the component remaining life with the associated uncertainty and of updating the prediction on the basis of observations of the degradation process, opens the door for effective condition-based replacement planning and risk informed life-extension for hazardous technologies, such as the nuclear, aerospace and chemical ones
Doktor Avram Josif Vinaver (1862-1915) - pionir srpske radiologije
No full textDr Abraham Joseph Vinaver (1862-1915), a Jew from Poland, was a pioneer of radiology in Serbia. He graduated from the Faculty of Medicine in Warsaw (1887) but lived and worked in Šabac (the Kingdom of Serbia) since 1890. He procured the first X-ray machine and developed a radiological service in Šabac five years after the discovery of X-rays. These were the beginnings of radiology in Serbia. He introduced the application of artesian wells. Dr Abraham Joseph Vinaver - a Participant at the First Congress of Serbian Physicians and Naturalists, Belgrade 1904. "The Diagnostic Importance of X-rays in Lung Disease, especially in Initial Tuberculosis" and "Five Years of Treatment by X-Ray Machines" were the first works in the field of radiology in Serbia by this author. Dr Abraham Joseph Vinaver - Reserve Medical Officer in the Serbian Army. During the Balkan Wars, he was a volunteer with the rank of major engaged in military corps and he participated in the First World War as well. He died of malaria in 1915 in Gevgelija. His dedication to work during the typhus epidemics was put into verses of a poem by his son Stanislav Vinaver. Dr Avram Vinaver Joseph was a nobleman with a great heart, who selflessly sacrificed himself for the Serbian people and Serbia. He gave his contribution to the development of health services in Serbia, both in peacetime and wartime conditions. Dr Abraham Joseph Vinaver laid the foundations for today’s radiology in SerbiaDoktor Avram Josif Vinaver (1862−1915), Jevrejin iz Poljske, bio je pionir srpske radiologije. Diplomirao je na Medicinskom fakultetu u Varšavi (1887). Od 1890. godine živeo je i radio u Šapcu (Kraljevina Srbija). Nabavio je prvi rendgenski aparat i razvio radiološku službu u Šapcu, pet godina po otkriću X-zraka. Bili su to počeci radiologije u Srbiji. Uveo je u primenu arterške bunare. Dr Avram Josif Vinaver − učesnik Prvog kongresa srpskih lekara i prirodnjaka, Beograd 1904. godine. „Dijagnostička važnost Rentgenovih zrakova kod bolesti pluća, naročito kod početne tuberkuloze” i „Pet godina lečenja Rentgenovim zracima” bila su prva saopštenja iz oblasti radiologije u Srbiji ovog autora. Dr Avram Josif Vinaver - rezervni sanitetski major srpske vojske. Za vreme Balkanskih ratova bio je dobrovoljac sa činom majora angažovan u vojnom sanitetu. Učesnik je i I svetskog rata. Umro je od malarije 1915. godine u Đevđeliji. O požrtvovanom radu dr Avrama Josifa Vinavera u vreme epidemije
pegavog tifusa u Srbiji svedoči i pesma njegovog sina Stanislava Vinavera. Doktor Avram Josif Vinaver je bio čovek plemenitog srca koji se nesebično žrtvovao za srpski narod
i Srbiju. Dao je doprinos razvoju zdravstvene zaštite stanovništva Srbije podjednako i u mirnodopskim i u ratnim uslovima. Doktor Avram Vinaver je postavio temelje današnje
radiologije u Srbiji
Condition-based maintenance by particle filtering
No full textThis paper presents the application of the particle filtering method, a model-based Monte Carlo method, for estimating the failure probability of a component subject to degradation based on a set of observations. The estimation is embedded within a scheme of condition-based maintenance of a component subject to fatigue crack growth. © Taylor & Francis Group, London.© 2009 Taylor & Francis Group
