Positive impact of 3D CAD models employment in descriptive geometry education
(Gliwice: PTGiGI, 2019)
Classical Descriptive Geometry (DG) course used 2D drawings for 3D spatial elements representation. Computer graphic introduced simulation of a 3D geometric environment in contemporary DG teaching. Research aim is the ...
On a generalized Jordan normal form of an infinite upper triangular matrix
(Taylor & Francis Ltd, United Kingdom, 2019)
Any square matrix over an algebraically closed field has a Jordan normal form. In this paper, we prove that every infinite upper triangular matrix over an arbitrary field has a generalized infinite Jordan normal form.
Geometrical, Fresnel, and Fraunhofer Regimes of Single-Slit Diffraction
(American Association of Physics Teachers - AAPT.org, 2019)
Recently, Panuski and Mungan presented the results of their study of light diffraction from a variable-width single slit by observing and measuring the diffraction pattern on an observation screen placed at a fixed distance. ...
Geometric Proportional Schemas of Serbian Medieval Raška Churches Based on Stambuk's Proportional Canon
(Birkhauser Verlag AG, 2019)
In this paper, an analysis of three Serbian medieval Raška churches highlights the significance of the interaction of regular geometric shapes in the composition of their underlying proportional scheme. The complex geometry ...
Note on Strongly Nil Clean Elements in Rings
(Springer New York LLC, 2019)
Let R be an associative unital ring and let a R be a strongly nil clean element. We introduce a new idea for examining the properties of these elements. This approach allows us to generalize some results on nil clean and ...
Perception of 3D Virtual Road Markings - Based on Estimation of Vehicle Speed
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2019)
Excessive speed and poor drivers' perception are the causes of a large number of traffic accidents. Analysis of the influence of geometry in drivers' behavior has been widely performed by different researchers. One way to ...
Experimental Study: How fast is the Children's Reaction Times for Different Heights of Traffic Signs - Ergonomic Principles and Traffic Safety Aspect
(International Engineering and Technology Institute (IETI), 2019)
Touchscreen devices have dramatically increased the accessibility and usage of technology, causing escalating usage, especially by very young children. Although the effects of screen time have been shown to produce serious ...
An experimental study on the certain effects of colors on the perception of preschool and primary school children – implications to design
(IETI Transactions on Ergonomics and Safety, 2019)
The adult ergonomic design principles usually do not apply to children, because their needs, skills, and expectations differ. The purpose of this study is to explore preschoolers' and primary schoolers' color perception ...
Using the ELECTRE MLO Multi-Criteria Decision-Making Method in Stepwise Benchmarking - Application in Higher Education.
(Operational Research in Engineering Sciences: Theory and Applications, 2019)
This paper describes multi-criteria decision making as a tool for stepwise benchmarking. The ELECTRE MLO ranking method is used. I give a mathematical theorem with a proof which is the answer to the question whether it is ...
An analytical approach based on Green's function to thermal response factors for composite planar structure with experimental validation
(Elsevier Masson SAS, 2019)
The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Green's Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature ...
