An Examination of Tourist Arrivals Dynamics Using Short-Term Time Series Data: A Space—Time Cluster Approach

2013

The purpose of this study is to examine the development of Italian tourist areas ( circoscrizioni turistiche) through a cluster analysis of short time series. The technique is an adaptation of the functional data analysis approach developed by Abraham et al (2003), which combines spline interpolation with k-means clustering. The findings indicate the presence of two patterns (increasing and stable) averagely characterizing groups of territories. Moreover, tests of spatial contiguity suggest the presence of ‘space–time clusters’; that is, areas in the same ‘time cluster’ are also spatially contiguous. These findings appear to be more robust in particular for those series characterized by an…

Muskuļu spēka un jaudas īpašību novērtēšana, izmantojot dinamiskā spēka un reaktīvā spēka indeksus

2022

Reaktīvā un dinamiskā spēka indeksa novērtēšana palīdz izveidot jaunu vai uzlabot jau esošu treniņu plānu, balstoties uz sportista individuālajām spējām un rādītājiem, novērtēt pliometriskās spējas un uzraudzīt nogurumu, un var palīdzēt sasniegt labākus rezultātus, kā arī samazināt traumu risku. Pētījuma mērķis ir salīdzināt metodes reaktīvā un dinamiskā spēka indeksu iegūšanai un, balstoties uz iegūtajiem datiem, izpētīt šo indeksu pielietošanu treniņu procesos. Pētījuma ietvaros tika pielietoti divi testa protokoli reaktīvā spēka indeksa iegūšanai un viens tests dinamiskā spēka indeksa iegūšanai. Pētījumam tika izvēlēti 12 dalībnieki, kuri veica sekojošos testus: Augstuma noteikšana lēcie…

Analysis of Exosomal Cargo Provides Accurate Clinical, Histologic and Mutational Information in Non-Small Cell Lung Cancer

2022

Simple Summary Non-small cell lung cancer (NSCLC) is the second most commonly diagnosed cancer and the leading cause of cancer-related death worldwide. Clinical decision-making depends on the histological classification; however, tissue biopsy is frequently not technically feasible due to tumor location or limited tissue samples. Therefore, we propose to find clinical, molecular and histological biomarkers using a minimally invasive approach based on the analysis of the cargo of the blood extracellular vesicles. Exosomes are membranous vesicles present in several biological fluids, which carry biological information to distant tissues, regulating several tumor processes. This study aims to …

DNA integrity in diagnosis of premalignant lesions

2020

Background Carcinogenesis is a dynamic process which traditional biopsying can not keep up with. Saliva as fluid in the vicinity of the tumor can offer better insights to this process. This study aimed to identify the accuracy of salivary DNA integrity index in differentiating between oral premalignant lesions and oral cancer. Material and Methods This phase II diagnostic test accuracy study included 93 patients divided into three groups: 30 oral cancer patients, 33 patients with oral premalignant lesions divided into 21 oral lichen planus patients and 12 patients with leukoplakia and 30 normal individuals who acted as controls. Oral rinse was collected from all participants and they all un…

A case formulation model for the assessment of psychological problems among deafblind persons

2012

In order to describe and understand possible problems associated with deafblindness we applied a functional analysis case formulation strategy and Functional Analytic Clinical Case Diagrams (FACCD). We collected clinical assessment data from deafblind persons who were experiencing multiple psychological problems as reported by their healthcare professionals. The data were collected after the healthcare professionals were trained in functional analyses and in applying FACCD. The 21 deafblind persons assessed by healthcare professionals were reported to have 3–11 psychological problems. Two case examples are given to illustrate the complexity of a deafblind person's life situation and the fun…

Standard testing of photovoltaic modules for use in renewable energy education

2015

A photovoltaic laboratory exercise has been devised and used in the educational curriculum of the Renewable Energy Programme at the University of Jyväskylä. The purpose of the experimental tasks is to give students of renewable energy a good understanding of standard testing procedures used in industry for characterising photovoltaic modules and to provide practical skills in sizing simple photovoltaic installations. Herein the experimental set-up, basic theory and measurement procedure are described. The experimental apparatus is simple to assemble and uses both standard laboratory equipment and recycled components. From the experimental results, the tested PV cell had a maximum efficiency…

Diaspora Start-Up Programs and Creative Industries: Evidence from Romania

2021

Romania is one of the main countries of origin for intra-European migration. The national authorities recently implemented the first major program —Diaspora Start-up—to support the business initiatives of Romanian citizens who live abroad and who are interested in opening a business in their home country. This scheme was developed in parallel with a broader program—Romania Start-up Plus—which was designed to support the entrepreneurial initiatives of individuals residing inside the country. These programs have already supported over 8,600 non-agricultural start-ups created in urban areas. This study conducted a comparative analysis of the two programs based on different criteria and explore…

The weathering test of polypropylene composites

2000

Polipropylen "Malen P" czysty (a), kompozyty na jego podstawie napełniane (20% mas.) kredą lub talkiem (b) oraz produkty te stabilizowane dodatkowo stabilizatorem UV typu HALS ("Tinuvin 791") (c) poddano badaniom laboratoryjnego starzenia atmosferycznego. Badane próbki poddawano działaniu promieniowania ultrafioletowego w dawkach do 950 MJ/m2, w zaprogramowanych warunkach temperatury, wilgotności oraz nadeszczania. Postęp fotodegradacji polimeru śledzono na podstawie zmian ciężaru cząsteczkowego, jego rozkładu (GPC) oraz wybranych właściwości mechanicznych (wydłużenia względnego, naprężenia zrywającego, udarności z karbem). Określono również odporność próbek badanych białych kompozytów na z…

Statistical analysis of the relation between metallic microstructures and mechanical properties

2020

This thesis aims at the development of physical relations between the intricate 3D features of metallic microstructures and the mechanical properties of the material. For understanding which are the microstructural determinants of the resultingmechanical behaviour of metals, a deep quantitative characterisation of the microstructure is needed. The main steps of quantitative characterisation of the microstructures are: identification of the phases distribution and their chemical composition, study of the microstructure morphology (geometrical arrangement of grains, grain boundaries, grain orientations, grain size and grain shape). An accurate description of the microstructure features enrich…
