Effects of environmental and management factors on species and trait composition in arable weed communities

Gyula Pinke

Publication Name: Botanikai Kozlemenyek

Publication Date: 2016-01-01

Volume: 103

Issue: 2

Page Range: 249-262

Description:

One of the exciting topics of weed science is to identify the most important ecological and management variables influencing the composition of arable weed communities. This paper reviews the findings of relevant publications from the last 15 years. According to floristic approaches six ecological (altitude, sea-sonality, temperature, precipitation, soil pH, soil texture) and three management variables (crop, preceding crop, degree of intensification) were most often identi-fied as the most important factors determining the species composition of arable weed communities. It can be concluded that there is a general positive correlation between the length of a gradient and its importance. According to functional approaches the most frequent correlations were found between the plant traits of stature, seed size, seed production, germination time, flowering period, life form and some specific variables.

Accreditation of forensic laboratories as a part of the “European Forensic Science 2020” concept in countries of the Visegrad Group

Mónika Nogel Gabor Kovacs Zsolt Pádár

Publication Name: Forensic Science International Genetics Supplement Series

Publication Date: 2015-12-01

Volume: 5

Issue: Unknown

Page Range: e412-e413

Description:

Globalising, cross-border crime has led EU Member States to improve methods of fighting crime on an international level as well as to increase the mutual recognition of collecting and analysing evidence by one another. In the interest of the regulated and scheduled implementation of the harmonization process, the Council of the EU made a decision of The Vision for European Forensic Science 2020 including the creation of a European Forensic Science Area and the development of forensic science infrastructure in Europe [EFSA 2020] to ensure the equivalence of professional forensic examinations. The collection, processing, use and delivery of forensic data will be based on equivalent minimum forensic science standards, and forensic service providers will work on the basis of a common approach to implement these standards that foster closer cooperation between them and criminal justice systems. The accreditation of forensic laboratories is a corner stone of the above mentioned objectives [1–3]. Ensuring the integrity of DNA profiles the Council issued decision 2008/616/JHA the application of EN ISO/IEC 17025 standard regarding the operation of testing and calibration laboratories has been ordered [4]. According to Council Framework Decision 2009/905/JHA on the accreditation of judicial expert laboratories, the laboratories have to be accredited until 30th November 2015 [5]. We investigated the regulations, decisions and rules national and international measures of the given area.

Primal domain decomposition method with direct and iterative solver for circuit-field-torque coupled parallel finite element method to electric machine modelling

Miklós Kuczmann Daniel Marcsa

Publication Name: Advances in Electrical and Electronic Engineering

Publication Date: 2015-12-01

Volume: 13

Issue: 5

Page Range: 458-465

Description:

The analysis and design of electromechanical devices involve the solution of large sparse linear systems, and require therefore high performance algorithms. In this paper, the primal Domain Decomposition Method (DDM) with parallel forward-backward and with parallel Preconditioned Conjugate Gradient (PCG) solvers are introduced in two-dimensional parallel time-stepping finite element formulation to analyze rotating machine considering the electromagnetic field, external circuit and rotor movement. The proposed parallel direct and the iterative solver with two preconditioners are analyzed concerning its computational efficiency and number of iterations of the solver with different preconditioners. Simulation results of a rotating machine is also presented.

MILP models for the optimization of real production lines

Tamás Hajba Zoltán Horváth

Publication Name: Central European Journal of Operations Research

Publication Date: 2015-12-01

Volume: 23

Issue: 4

Page Range: 899-912

Description:

A special class of the permutation flow shop problems (PFSPs) with makespan minimization which contains repeated jobs, limited buffer sizes between the machines and fixed number of palettes that carry the jobs on the production line is introduced in this paper. We define the related PB-R-PFSP, the Permutation with Repetition Flow Shop Problem with Palettes and Buffers, and construct new mixed integer linear programming (MILP) models for this problem. The effectiveness of the MILP models and the influence of the number of palettes and buffers on the problems are investigated experimentally.

A survey of assistive technologies and applications for blind users on mobile platforms: a review and foundation for research

Adam B. Csapo Hunor Nagy György Wersényi Tony Stockman

Publication Name: Journal on Multimodal User Interfaces

Publication Date: 2015-12-01

Volume: 9

Issue: 4

Page Range: 275-286

Description:

This paper summarizes recent developments in audio and tactile feedback based assistive technologies targeting the blind community. Current technology allows applications to be efficiently distributed and run on mobile and handheld devices, even in cases where computational requirements are significant. As a result, electronic travel aids, navigational assistance modules, text-to-speech applications, as well as virtual audio displays which combine audio with haptic channels are becoming integrated into standard mobile devices. This trend, combined with the appearance of increasingly user-friendly interfaces and modes of interaction has opened a variety of new perspectives for the rehabilitation and training of users with visual impairments. The goal of this paper is to provide an overview of these developments based on recent advances in basic research and application development. Using this overview as a foundation, an agenda is outlined for future research in mobile interaction design with respect to users with special needs, as well as ultimately in relation to sensor-bridging applications in general.

Levels of what and how in the education of geo-engineering on problematic soils

Róbert Szepesházi P. Scharle Richard P. Ray

Publication Name: Geotechnical Engineering

Publication Date: 2015-12-01

Volume: 46

Issue: 4

Page Range: 110-113

Description:

Majority of recent studies discussing the development issues of civil engineering education focus the attention on the innovative teaching and learning methods. Evolution of the engineers' habit of mind demands, in addition, the conscious harmonization and synchronization of educational level, basic mathematical and mechanical preliminaries and professional content. Consideration of the interdependence among these factors results in some conclusions usable for educators interested in creating innovative curricula. Distinction between BEng and MEng levels of competence has to be identified properly. Geotechnical works on or in problematic soils deserve this attention, in particular.

Misinterpretation of sample contamination in a Hungarian casework

Gabor Kovacs Zsolt Pádár

Publication Name: Forensic Science International Genetics Supplement Series

Publication Date: 2015-12-01

Volume: 5

Issue: Unknown

Page Range: e425-e427

Description:

The risk of contamination is a generally recognized and intensively researched field of forensic DNA [1–5]. In spite of quality assurance systems, recommendations and regulations, this risk is always present even in routine casework as evidenced by this example from Hungary. In a murder case, buried bodies were discovered and exhumed. The genetic analyses of remains were performed in two different laboratories (A and B). In case of unidentifiable N.N. body the first analysis in “Lab A” used the soft tissues (muscle) from bone sample. Based on the results, the first two opinions of “Lab A” excluded the biological relationship of N.N. with the putative relatives. The subsequent analysis of “Lab B” used the soft tissue parallel to the bone sample from the N.N. body, and the opinion supported the hypothesis of biological (maternal) relationship with high probability (W = 99.999%). We examined and tried to resolve the contradictions presented by the two interpretations, which originate from contamination of the remaining soft tissue.
