Application of a Knowledge Discovery Process to Study Instances of Capacitated Vehicle Routing Problems
2020
Vehicle Routing Problems (VRP) are computationally challenging, constrained optimization problems, which have central role in logistics management. Usually different solvers are being developed and applied for different kind of problems. However, if descriptive and general features could be extracted to describe such problems and their solution attempts, then one could apply data mining and machine learning methods in order to discover general knowledge on such problems. The aim then would be to improve understanding of the most important characteristics of VRPs from both efficient solution and utilization points of view. The purpose of this article is to address these challenges by proposi…
The b-chromatic number of power graphs
2003
The b-chromatic number of a graph G is defined as the maximum number k of colors that can be used to color the vertices of G, such that we obtain a proper coloring and each color i, with 1 ≤ i≤ k, has at least one representant x_i adjacent to a vertex of every color j, 1 ≤ j ≠ i ≤ k. In this paper, we discuss the b-chromatic number of some power graphs. We give the exact value of the b-chromatic number of power paths and power complete binary trees, and we bound the b-chromatic number of power cycles.
Nozīmes veidošana attēlos: lingvistiskā un paralingvistiskā perspektīva
2021
Darba mērķis ir izpētīt, kā attēlu nozīmi iespējams interpretēt noteiktā kontekstā. Pētījums reaģē uz galējās interpretācijas problemātiku un ierosina skatīt Čārlza Pīrsa zīmju teoriju kā instrumentu, kas ļauj analizēt nozīmes radīšanas un interpretācijas procesualitāti noteiktas situācijas un kultūras kontekstā. Tiek pētīti četri atšķirīgi attēlu gadījumi (Hilma af Klinta, Sajs Tvomblijs, Gerhards Rihters un Vija Celmiņa), piemērojot mainīgos konteksta lielumus un Pīrsa zīmju klasifikācijas. Vijas Celmiņas intervijas fonētiskā un runātā diskursa analīze liecina, ka mākslinieces runātais teksts var attīstīt uztvērēja priekšzinās…
Facilitation of goal-setting and follow-up in an internet intervention for health and wellness
2010
Chronic work-related stress and insufficient recovery from workload can gradually lead to problems with mental and physical health. Resources in healthcare are limited especially for preventive treatment, but low-cost support can be provided by Internet-based behavior change interventions. This paper describes the design of an Internet intervention which supports working-age people in managing and preventing stress-related health and wellness problems. The intervention is designed for early prevention and aims to motivate individuals to take responsibility for their own well-being. It allows them to choose the approach to take to address personally significant issues, while guiding them thr…
Pratiche di conoscenza e fruizione collettiva per un’accessibilità fisica e culturale del patrimonio monumentale
2022
I-Access, progetto Interreg Italia-Malta, si interroga sui temi dell’accessibilità fisica e culturale nei centri storici delle città di Palermo e La Valletta, accomunati da storie parallele di uomini, monumenti, spazi urbani. E lo fa con la costituzione di un gruppo formato da esperti di restauro architettonico e di design della comunicazione visiva, facendo dialogare i due ambiti disciplinari che condividono metodologie e strumenti di lavoro. In tal modo i dati materici e storiografici raccolti dai primi vengono tradotti in configurazioni visibili, leggibili, ordinate, in cui la nuova struttura narrativa consente la corretta accessibilità culturale del monumento e della sua storia. Insieme…
Incentive Mechanism for Edge-Computing-Based Blockchain
2020
Blockchain has been gradually applied to different Internet of Things (IoT) platforms. As the efficiency of the blockchain mainly depends on the network computing capability, how to make sure the acquisition of the computational resources and participation of the devices would be the driving force. In this work, we focus on investigating incentive mechanism for rational miners to purchase the computational resources. A edge computing-based blockchain network is considered, where the edge service provider (ESP) can provide computational resources for the miners. Accordingly, we formulate a two-stage Stackelberg game between the miners and ESP. The aim is to investigate Stackelberg equilibriu…
Initial Coin Offering (ICO) as a Fundraising Strategy : A Multiple Case Study on Success Factors
2019
Cryptocurrencies and Initial Coin Offerings (ICO) are some of the more prominent examples of currently used blockchain technology applications. Especially software startups have leveraged ICOs to gain funding early on in their lifecycles, going on to develop and create new blockchain based applications. Recently, larger companies such as Facebook have also begun to show interest in cryptocurrency, although thus far not for funding purposes in the form of ICOs. In this paper, we investigate factors that positively affect the abilities of companies to meet their fundraising goals via ICOs. We first identify a set of factors from extant literature and then seek to further confirm the effect of…
Blockchain applications in management: A bibliometric analysis and literature review
2021
Blockchain has gained substantial recognition for its ability to induce transformation and innovation in existing business models and frameworks. Consequently, the application of this technology to the management domain and its processes has attracted increasing interest from academia and industry. Although research addressing the use of blockchain in management has gained momentum, this field presents a discontinuous overview of the current scope and boundary of the knowledge thereon. This study addresses this lacuna using bibliometric analyses to synthesize the prior literature. Data from Scopus 586 articles, entailing contributions from 72 countries, 273 journals, 1016 organizations, and…

Impact Assessment of Skidding Extraction: Effects on Physical and Chemical Properties of Forest Soils and on Maple Seedling Growing along the Skid Tr…
2019
Several studies investigated soil disturbances caused on skid trails by forest logging. However, there is still a lack of knowledge about the severity and the distance of disturbances along both sides from the trails. The aims of this study were: i) to investigate the changes in physical and chemical properties of soil along the sides of skidding trails
