Evaluating the Efficiency of Different Regression, Decision Tree, and Bayesian Machine Learning Algorithms in Spatial Piping Erosion Susceptibility U…

2020

Piping erosion is one form of water erosion that leads to significant changes in the landscape and environmental degradation. In the present study, we evaluated piping erosion modeling in the Zarandieh watershed of Markazi province in Iran based on random forest (RF), support vector machine (SVM), and Bayesian generalized linear models (Bayesian GLM) machine learning algorithms. For this goal, due to the importance of various geo-environmental and soil properties in the evolution and creation of piping erosion, 18 variables were considered for modeling the piping erosion susceptibility in the Zarandieh watershed. A total of 152 points of piping erosion were recognized in the study area that…

Spatial representations of future in Homeric Greek

2015

The aim of this paper is to investigate the space-time mapping of the future in Homeric Greek. It is widely accepted that the spatial adverbs πρόσσω ‘in front’ and ὀπίσσω ‘behind’ in the Homeric poems are used to portray temporal events located in a sequence of aligned entities that follow one after the other on the same path (Dunkel, 1983, p. 66). In such a temporal sequence, or Time-rp model, those adverbs are associated respectively to past and future events in a bipartite spatial representation of time, without involving a deictic ego-experiencer. After analyzing data from the Homeric poems in a cognitive linguistic perspective, it is found that some temporal uses of the preposition πρό…

Existence of positive solutions for nonlinear Dirichlet problems with gradient dependence and arbitrary growth

2018

We consider a nonlinear elliptic problem driven by the Dirichlet $p$-Laplacian and a reaction term which depends also on the gradient (convection). No growth condition is imposed on the reaction term $f(z, \cdot,y)$. Using topological tools and the asymptotic analysis of a family of perturbed problems, we prove the existence of a positive smooth solution.

The existence of solutions for the modified (p(x), q(x))-Kirchhoff equation

2022

We consider the Dirichlet problem-Delta(Kp)(p(x))u(x) - Delta(Kq)(q(x))u(x) = f(x, u(x), del u(x)) in Omega, u vertical bar(partial derivative Omega) = 0,driven by the sum of a p(x)-Laplacian operator and of a q(x)-Laplacian operator, both of them weighted by indefinite (sign-changing) Kirchhoff type terms. We establish the existence of weak solution and strong generalized solution, using topological tools (properties of Galerkin basis and of Nemitsky map). In the particular case of a positive Kirchhoff term, we obtain the existence of weak solution (= strong generalized solution), using the properties of pseudomonotone operators.

Personnel analysis and its reliability

2014

Tässä tutkimuksessa selvitetään rekrytointi- ja henkilöarviointiyritys MindFit Consulting Oy:n työnhakijoista tekemien henkilöanalyysiraporttien, MindFitin henkilöanalyysien, luotettavuutta. Tarkoitus on tutkia, kuinka yhdenmukaisesti analyysien lukijat ymmärtävät analyysien sisällön. Tutkimuksessa luodaan kyselylomake, jonka avulla eri analyysiraportin lukijat pisteyttävät analyysien sisällön. Lukijoiden antamien pisteiden yhdenmukaisuus mitataan analyysien luotettavuuden (inter-rater reliability) selvittämiseksi. Tutkittavat henkilöanalyysit ovat sanallisia raportteja työnhakijoista. Käytännössä analyysiteksti operationalisoidaan kriteereiksi, jotka voidaan pisteyttää numeerisesti kyselyl…

Applications of Microlocal Analysis in Inverse Problems

2020

This note reviews certain classical applications of microlocal analysis in inverse problems. The text is based on lecture notes for a postgraduate level minicourse on applications of microlocal analysis in inverse problems, given in Helsinki and Shanghai in June 2019.

Calculating cohomology groups of $overline M_0,n(mathbb P^r,d)$

2003

Here we investigate the rational cohomology of the moduli space ℳ̄0,n (ℙr,d) of degree d stable maps from n-pointed rational curves to ℙr. We obtain partial results for small values of d with an inductive method inspired by a paper of Enrico Arbarello and Maurizio Cornalba.

Glicerīna transportsistēmas un Hog1 loma raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī

2015

Šī darba mērķis bija izpētīt glicerīna transportsistēmu un Hog1p iespējamo lomu raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī. Lai sasniegtu šo mērķi, izmantoja raugu Saccharomyces cerevisiae BY4741 un tā izogēnos celmus, kuriem trūka viens vai vairāki gēni, kuri ir atbildīgi par glicerīna transportiera Stl1p, glicerīna eksporta kanāla Fps1p un regulatorās Hog1p MAP kināzes ekspresiju raugu šūnās. Darbam bija izvirzīti sekojošie uzdevumi: izpētīt S. cerevisiae BY4741 spējas pāriet anhidrobiozes stāvoklī; novērtēt glicerīna transportsistēmu Stl1p un Fps1p, ka arī Hog1p ietekmi uz raugu šūnu rezistenci pret dehidratāciju; izpētīt raugu spējas pārdzīvot osmotisko stresu un šīs ied…
