Characterizing Cavities in Model Inclusion Fullerenes: A Comparative Study
2001
Abstract: The fullerene-82 cavity is selected as a model system in order to test several methods for characterizing inclusion molecules. The methods are based on different technical foundations such as a square and triangular tessellation of the molecular surface, spherical tessellation of the molecular surface, numerical integration of the atomic volumes and surfaces, triangular tessellation of the molecular surface, and cubic lattice approach to the molecular volume. Accurate measures of the molecular volume and surface area have been performed with the pseudorandom Monte Carlo (MCVS) and uniform Monte Carlo (UMCVS) methods. These calculations serve as a reference for the rest of the meth…
Johdatus fraktaaliderivaattoihin ja niiden sovelluksiin
2014
Fraktaaliderivaatta on derivaatta, jonka kertaluku on reaali- tai kompleksiluku. Fraktaaliderivaatta voidaan määritellä usealla eri tavalla, mutta mikään määritelmä ei ole selkeästi muita parempi. Koska fraktaaliderivaatan ominaisuudet riippuvat valitusta määritelmästä, ominaisuuksia ei voida suoraan yleistää kaikille fraktaaliderivaatoille. Tämän tutkielman tarkoitus on antaa lukijalle perustiedot reaalilukukertaisista fraktaaliderivaatoista ja niiden määritelmäsidonnaisista ominaisuuksista. Tutkielmassa esitellään kolme yleisimmin viitattua määritelmää: Grünwald-Letnikov, Riemann-Liouville ja Caputo. Grünwald-Letnikovin määritelmä yleistää klassisen derivaatan määritelmän suoraan reaali- …

Building on 150 Years of Knowledge : The Freshwater Isopod Asellus aquaticus as an Integrative Eco-Evolutionary Model System
2021
Interactions between organisms and their environments are central to how biological diversity arises and how natural populations and ecosystems respond to environmental change. These interactions involve processes by which phenotypes are affected by or respond to external conditions (e.g., via phenotypic plasticity or natural selection) as well as processes by which organisms reciprocally interact with the environment (e.g., via eco-evolutionary feedbacks). Organism-environment interactions can be highly dynamic and operate on different hierarchical levels, from genes and phenotypes to populations, communities, and ecosystems. Therefore, the study of organism-environment interactions requir…
Design and simulation of efficient combinational circuits based on a new XOR structure in QCA technology
2021
AbstractQuantum-dot cellular automata (QCA), due to its unique characteristics like low power consumption, nanoscale design, and high computing speed is considered as an emerging technology, and it can be used as an alternative for CMOS technology in circuit design for quantum computers in the near future. XOR gate has many applications in the design of digital circuits in QCA. In this paper, an efficient novel structure of XOR gate is proposed in QCA. Also, a novel 1-bit comparator circuit, 1-bit full adder, binary to gray and gray to binary convertor code based on the proposed XOR is designed and simulated using QCADesigner 2.0.3. The simulation results demonstrated that the proposed stru…
Cross-border integration of universities as a possible research topic in border studies
2021
The text deals with the cross-border cooperation of universities as a possible new research topic in border studies. We identified two important associations of universities operating in border areas in the EU core and two associations gathering universities from Czech, Polish and Slovak areas. Then we tried to identify the areas in which these universities cooperate. It turned out that the principal difference is in a significantly higher number of joint study programs. This has probably a link to the high cross-border integration in the EU core. We believe that the topic is promising and deserves much higher attention, as it probably points at new and not really exploited cross-border int…
Spherical harmonic expansion of fundamental solutions and their derivatives for homogenous elliptic operators
2017
In this work, a unified scheme for computing the fundamental solutions of a three-dimensional homogeneous elliptic partial differential operator is presented. The scheme is based on the Rayleigh expansion and on the Fourier representation of a homogeneous function. The scheme has the advantage of expressing the fundamental solutions and their derivatives up to the desired order without any term-by-term differentiation. Moreover, the coefficients of the series need to be computed only once, thus making the presented scheme attractive for numerical implementation. The scheme is employed to compute the fundamental solution of isotropic elasticity showing that the spherical harmonics expansions…
Wybrane zagadnienia związane z dydaktyką całkowania funkcji wymiernych
2018
Jednym z rodzajów całek przedstawianych w procesie dydaktycznym są całki wyrażeń wymiernych. Techniki rozwiązywania tego rodzaju całek są wielorakie, niemniej w literaturze i dydaktyce wykorzystywana jest zazwyczaj jedna metoda. Metoda ta jest uniwersalna ale czasochłonna i nie lubiana przez studentów. Poniższy artykuł stanowi kompendium metod umożliwiających rozwiązywanie całek funkcji wymiernych.
Fuusion jälkeinen IT-integraatio kuntaliitoksessa
2011
Yritykset tavoittelevat fuusioilla tyypillisesti nopeaa kasvua tai aiempaa vahvempaa markkina-asemaa. Vastaavasti kunnat pyrkivät kohentamaan talouttaan ja parantamaan palveluntuotantoaan kuntaliitosten avulla. Fuusioihin keskeisesti liittyvässä IT-toimintojen yhteensovittamisessa kuitenkin usein epäonnistutaan. Tässä tutkielmassa tarkastellaan fuusion jälkeisen IT-integraation läpivientiä strategisesta näkökulmasta, selvitetään millaisia välineitä kirjallisuus tarjoaa fuusion jälkeisen IT-integraation läpiviennin arvioimiseen ja selvitetään, miten järjestelmäintegraation läpiviennissä onnistuttiin Jyväskylän kaupungin, Jyväskylän maalaiskunnan ja Korpilahden kunnan välisessä kuntaliitokses…
