Condition classification of fibre ropes during cyclic bend over sheave testing using machine learning
2022
Fibre ropes have been shown to be a viable alternative to steel wire rope for offshore lifting operations. Visual inspection remains a common method of fibre rope condition monitoring and has the potential to be further automated by machine learning. This would provide a valuable aid to current inspection frameworks to make more accurate decisions on recertification or retirement of fibre ropes in operational use. Three different machine learning algorithms: decision tree, random forest and support vector machine are compared to classical statistical approaches such as logistic regression, k-nearest neighbours and Naïve-Bayes for condition classification for fibre ropes under cyclic-bend-ov…
Impact of the recommendations on the vaccination of the tetanus–diphtheria in the labor area
2017
Abstract Objective Our aim is evaluate vaccination guidelines that were published by Ministry of Health of Spain and his impact in a mutual injuries work of Spain (FREMAP). Method Is a retrospective observational study of vaccination with tetanus–diphtheria (Td) in adults of mutual injuries of work of Spain (FREMAP) between January 2010 and December 2013. Results We have registered 126,101 injured employees for vaccination; of those have been vaccinated 11,468 (9%). We have not found significant differences in employees with incapacity or no. We have not found significant differences by sex. We have found significant differences by age group (46–55 years), women more than men (χ2 = 4.422; p…
Globalizācija un patērētāju drošība. Gana-CEPS muitas akcīzes un profilakses dienesta gadījumu izpēte
2019
Pētījuma mērķis ir noskaidrot globalizācijas ietekmi uz patērētāju drošību, saskaņoti analizējot pasaules preču, pakalpojumu un viltošanas un pirātisma darbības, koncentrējoties uz Ganas ekonomiku. Pētījumā tika izmantoti primāri kvalitatīvie dati no Ganas akcīzes un profilakses pakalpojumiem (CEPS), lai noskaidrotu preču un pakalpojumu viltošanas un pirātisma pakāpi Ganā. Tas ir vispārējs pētījums, lai noteiktu viltošanas pakāpi no dažādām ekonomikas nozarēm; pārtikas produkti, dzērieni, farmācija, ķimikālijas, automobiļi, lauksaimniecība uc, analizējot ekspertu viedokļus un novērojumus, izmantojot strukturētu atklātu un slēgtu anketu dizainu. Pētījumu metodoloģijā tika izmantotas gan kval…
Safrāna audzēšana Ukrainā
2019
Maģistra darbā ‘’Safrāna audzēšana Ukrainā’’ tiek izstrādāts unikāls biznesa projekts jauna uzņēmuma dibināšanai, ar mērķi audzēt bioloģisku safrānu un to realizēt vairumtirdzniecībā ne tikai Latvijā, bet visā pasaulē. Maģistra darbā tiek risināta konkrētā problēma par ierobežotu safrāna vairumtirgotāju skaitu, piedāvājot papildināt tirgu ar vienu jaunu šādu saimniecību, kas safrānu audzēs Ukrainā. Problēmas apzināšanai tika veikts pētījums par safrāna pielietošanu, audzēšanas priekšnosacījumiem, safrāna pieejamību Rīgā, kā arī veikta patērētāju, restorānu, Latvijas farmācijas un kosmētikas ražotāju aptauja. Darbs sastāv no 80 lappusēm, 21 attēla, 11 tabulām un 30 pielikumiem. Atslēgas vārd…
Growing significance of safe tourism during pandemic.
2020
Drošība mūsdienu pasaulē ir ārkārtīgi nozīmīgā problēma. Tūrisma nozare ir pastāvīgi saistīta ar dažādu draudu un risku rašanos. Tūrisma attīstība ir saistīta ar ekonomisko un sociālo ietekmi, rada papildus ienākumus valstij. Šī darba aktualitāte ir saistīta ar to, ka tūrisma nozare ieņem svarīgu vietu Latvijas ekonomikā, apkalpojot miljoniem cilvēku gadā, tādejādi ir nepieciešams veltīt šīs nozares uzturēšanai un veicināšanai īpašu uzmanību. Tūrismam ir liela ietekme uz vēsturiskā un kulturālā saglabāšanu kā arī dabas, vēstures un kultūras potenciāla attīstīšanai Latvijā, tāpēc ir svarīgi pētīt un izstrādāt attīstības stratēģijas tūrisma nozarē un tā veicināšanas iespējas Covid-19 pandēmij…
A Personalist Ontological Approach to Synthetic Biology
2015
Although synthetic biology is a promising discipline, it also raises serious ethical questions that must be addressed in order to prevent unwanted consequences and to ensure that its progress leads toward the good of all. Questions arise about the role of this discipline in a possible redefinition of the concept of life and its creation. With regard to the products of synthetic biology, the moral status that they should be given as well as the ethically correct way to behave towards them are not clear. Moreover, risks that could result from a misuse of this technology or from an accidental release of synthetic organisms into the environment cannot be ignored; concerns about biosecurity and …
Commentaries on our new ways of perceiving disasters
2010
PurposeThe purpose of this paper is to help readers gain more understanding of the new phenomena of terror, risk, and threat perception.Design/methodology/approachVarious authors are reviewed: Castel, Beck, Baral, Kellner, Sabada, Korstanje, and in particular, Baudrillard.FindingsSeveral matches are found among the reviewed authors which comprise, for example: late modernity (from 1970 to date) witnesses an increase of fears, panic, and risk assessments in social imaginary; these concerns are part of a process that opens the future to the contingency. That way, the decision‐making process in human beings sheds light on certain aspects of life such as health, body‐care planning but this has …
Media constructions of fear in the outbreak of an epidemic disease
2016
Purpose – After almost a decade, the re-appearance of dengue fever in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay, where prevention policies have been followed, the future of dengue is uncertain in Argentina; the present paper does not have political affiliation but the purpose of this paper is to emphasizes the role that mass media plays in the coverage of epidemics. Design/methodology/approach – In moments of disorder, uncertainness or disaster, societies experience a shift in the ways they perceive their reality. Findings – In the times, media plays a dominant role in constructing the reality that the authors get to consume. Such reality is reflective of media’…
Perceived safety and attributed value as predictors of the intention to use autonomous vehicles: A national study with Spanish drivers
2019
Abstract Sooner than later, the growing development of Autonomous Vehicles (AVs) will represent not only an imminent transformation of transportation dynamics, but also further advantages for their users, including many improvements in road crash prevention, efficiency and sustainability. However, different concerns and constraints may affect the intention of adopting this technology among its potential customers, especially for what concerns those constraints related to safety, viability and stability. The objective of this study was to examine the influence of perceived safety and value attributed to the AV in the drivers’ intention to use it, considering the drivers’ demographic factors,…
Qualitative models of equipment units and their use in automatic HAZOP analysis
2000
Abstract The use of qualitative models in a support system for HAZOP analyses, in connection with an algorithm for finding the causes and the consequences of variable deviations, is described. The models use several representation structures among which mini-trees constitute the most important from the logical-functional point of view. The models are conceived both for continuous and batch plants. For the latter procedures, regulating the use of equipment units are also modelled using similar structures while equipment units are considered in various phases of their functioning. A brief description of the prototype support system, in which the models are implemented, is also given.
