1. NEW THEORETICAL INVESTIGATIONS ON THE GAP OF THE SKIVING STOCK PROBLEM
ABSTRACT The one-dimensional skiving stock problem is a combinatorial optimization problem being of high relevance whenever an efficient and sustainable utilization of given resources is intended. In the classical formulation, a given supply of (small) item lengths has to be used to build as many large objects (specified by some target length) as possible. F

3. Contact phenomena modeling in biological structures on the example of the implant-bone
Abstract The work presents modeling of interface phenomena in biological structures. Selected ways of numerical modeling of phenomena at the boundary of two materials by means of FEM methods are discussed. The work focuses on phenomena related to biological structures and their mutual interactions. Using an example of an implant-bone system, various techniqu

4. Topographic modelling using UAVs compared with traditional survey methods in mining
Abstract The current developments with unmanned aerial vehicles (‘UAVs’) are revolutionizing many fields in civil applications, such as agriculture, environmental and visual inspections. The mining industry can also benefit from UAVs in many aspects, and the reconciliation through topographic control is an example. In comparison with traditional topograp

5. An Active Search Method for Finding Objects with Near-Optimal Property Values within a Given Set
This paper proposes an active search method aimed at finding objects with optimal or near-optimal y-property values, on the basis of x-variables obtained by indirect, less costly methods. The proposed method progresses in a sequential manner, starting from a small subset of objects with known y-values. At each iteration, the K-nearest neighbour regression te

6. Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara (Hymenoptera, Formicidae)
ABSTRACT Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara. Leaf-cutting ants of the genus Atta build long physical trails by cutting the vegetation growing on the soil surface and removing the small objects they find across their path. Little is known on the dynamics of trail construction in these ants. How much time do

7. Conocimiento matemático de futuros profesores para la enseñanza de la probabilidad desde el enfoque frecuencial
The aim of this research was to assess mathematical knowledge for teaching probability (using a frequentist approach) in prospective elementary teachers. Common knowledge of content is analysed based on individual answers to an open problem by 157 Spanish prospective primary school teachers. After discussing with the participants their responses to the probl

8. Problemas de corte com sobras aproveitáveis e eliminação de simetrias / Cutting stock problems with usable leftover and symmetry breaking
In this work we study two variations of the packing problem where identical rectangular items must be packed into a polyhedron. One of the variations consists in finding the largest amount of rectangular items that can fit in a polyhedron. The other one consists in finding a minimal area polyhedron of a certain type that packs a set of rectangular identical

9. Formação estelar no complexo de nuvens moleculares em Monoceros / Star Formation in the Molecular Cloud Complex in Monoceros
We compare two molecular clouds of the Monoceros Complex in order to study their physical conditions related to the early stages of star formation. The selected clouds, Rosette (RMC) and Monoceros R2 (Mon R2), are interesting regions due to their characteristics that may be confronted with the hypothesis of star formation triggered by high velocity clouds (H

10. A estrutura argumental da língua karitiana: desafios descritivos e teóricos / Argument structure in Karitiana: theoretical and descriptive challenges
This masters thesis aims to describe the argument structure in Karitiana (Tupi branch, Arikém family, about 400 speakers) both in a theoretical and in a descriptive perspective. In this work, the challenge is to describe the verb classes identified in Karitiana in the formal theory of argument structure proposed by Hale and Keyser (2002). The work is divide
