Objective-constraint Mutual-guided Surrogate-based Particle Swarm Optimization for Expensive Constrained Multimodal Problems
(IEEE, 2023)Expensive constraint multimodal optimization problems (ECMMOPs) have such characteristics as expensive objectives and constraints, and multiple optimal modalities simultaneously, which pose severe challenges to evolutionary ...

Observations of crayfish plague infections in commercially important narrow-clawed crayfish populations in Turkey
(EDP Sciences, 2018)We studied the presence of possible Aphanomyces astaci infections in eight Turkish narrow-clawed crayfish (Astacus leptodactylus) populations by analyzing the prevalence and genotypes of the disease agent A. astaci. The ...Tieteelliset aikakauslehtiartikkelit

Observations on aerosol optical properties and scavenging during cloud events
(Copernicus GmbH, 2021)Long-term statistics of atmospheric aerosol and especially cloud scavenging were studied at the Puijo measurement station in Kuopio, Finland, during October 2010–November 2014. Aerosol size distributions, scattering ...Tieteelliset aikakauslehtiartikkelit

Obstructive sleep apnea: Do positional patients become nonpositional patients with time?
(Wiley, 2019)Objectives Obstructive sleep apnea (OSA) patients with breathing abnormalities only or mainly in the supine posture are designated positional patients (PPs), whereas nonpositional patients (NPPs) have many breathing ...Tieteelliset aikakauslehtiartikkelit

Occupational exposure to gaseous and particulate contaminants originating from additive manufacturing of liquid, powdered and filament plastic materials and related post-processes
(Informa UK Limited, 2019)The aim of this study was to measure the concentrations of gaseous and particulate contaminants originated from additive manufacturing operations and post-processes in an occupational setting when plastics were used as ...Tieteelliset aikakauslehtiartikkelit

Offspring Phenotype Is Shaped by the Non-Sperm Fraction of Semen
(Wiley, 2020)In a large majority of animal species, the only contribution of males to the next generation has been assumed to be their genes (sperm). However, along with sperm, seminal plasma contains a wide array of extracellular ...Tieteelliset aikakauslehtiartikkelit

On Becker's univalence criterion
(Elsevier BV, 2017)We study locally univalent functions f analytic in the unit disc D of the complex plane such that |f"(z)/f'(z)| (1 − |z|2) ≤ 1 + C(1 − |z|) holds for all z ∈ D, for some C ∈ (0,∞). If C ≤ 1, then f is univalent by Becker's ...info:eu-repo/semantics/article

On computer science major students' motivation in a practically oriented robotics course
(ACM, 2018)Educational robotics is considered to motivate students to learn principles of computing and computational thinking in many contexts. In this paper, we present the first experiences from our recent multimodal ...conferenceObject

On existence of solutions for Boltzmann Continuous Slowing Down transport equation
(Elsevier BV, 2018)The paper considers a linear Boltzmann transport equation (BTE), and its Continuous Slowing Down Approximation (CSDA). These equations are used to model the transport of particles e.g. in dose calculation of radiation ...info:eu-repo/semantics/article

On island model performance for cooperative real-valued multi-objective genetic algorithms
(Springer International Publishing, 2018)Solving a multi-objective optimization problem results in a Pareto front approximation, and it differs from single-objective optimization, requiring specific search strategies. These strategies, mostly fitness assignment, ...Artikkelit ja abstraktit tieteellisissä konferenssijulkaisuissa

On mappings of finite distortion that are quasiconformal in the unit disk
(Springer Nature, 2022)We study quasiconformal mappings of the unit disk that have homeomorphic planar extension with controlled distortion. For these mappings we prove a bound for the modulus of continuity of the inverse map, which somewhat ...

On the Application of Linear Programming on a Transportation Problem
(International Business Information Management Association (IBIMA), 2021)This research demonstrates the application of Linear programming on a transportation problem to products of Lubcon limited. Data were collected as extracts from the records of the company on the five (5) ...Artikkelit ja abstraktit tieteellisissä konferenssijulkaisuissa

On the composition of ammonia–sulfuric-acid ion clusters during aerosol particle formation
(Copernicus GmbH, 2015)The formation of particles from precursor vapors is an important source of atmospheric aerosol. Research at the Cosmics Leaving OUtdoor Droplets (CLOUD) facility at CERN tries to elucidate which vapors are responsible for ...info:eu-repo/semantics/article

On the Discrete Weibull Marshall-Olkin Family of Distributions: Properties, Characterizations, and Applications
(MDPI AG, 2021)In this article, we introduce a new flexible discrete family of distributions, which accommodates wide collection of monotone failure rates. A sub-model of geometric distribution or a discrete generalization of the exponential ...Tieteelliset aikakauslehtiartikkelit

On the early studies recognizing the role of sulphuric acid in atmospheric haze and new particle formation
(Informa UK Limited, 2018)Atmospheric aerosols have been a subject to scientific interest at least since the Age of Enlightenment, including theories concerning the origins of atmospheric haze and dust. Early studies associated haze with geological ...Tieteelliset aikakauslehtiartikkelit

On the limit of superhydrophobicity : defining the minimum amount of TiO2 nanoparticle coating
(IOP Publishing, 2019)Fabrication of superhydrophobic surfaces in large scale has been in high interest for several years, also titanium oxide nanostructures having been applied for the purpose. Optimizing the amount and structure of the TiO2 ...Tieteelliset aikakauslehtiartikkelit

On the limits of automatic speaker verification: Explaining degraded recognizer scores through acoustic changes resulting from voice disguise
(Acoustical Society of America (ASA), 2019)In speaker verification research, objective performance benchmarking of listeners and automatic speaker verification (ASV) systems are of key importance in understanding the limits of speaker recognition. While the adoption ...Tieteelliset aikakauslehtiartikkelit

On the limits of real-valued functions in sets involving Ψ-density, and applications
(Elsevier BV, 2021)New results on upper and lower limits of real-valued functions are proved by means of ψ-densities introduced by P. D. Barry in 1962. This leads to improvements of several existing results on the growth of non-decreasing ...Tieteelliset aikakauslehtiartikkelit
