Nowadays, computer-models play an important role in the presentation of architectural designs. Despite the widespread computer advances, many architects still find hand-drawn sketches useful. Some designers use existing rules to draw a specific perspective view of the observer on the paper. In this research, the very first steps of this conversion are studied and introduced as a preface for further investigation into more complicated sketches. The authors try to use the python programming language to develop an interactive platform in Grasshopper. In this system, a 2D hand-drawn perspective can be imported and converted to a simplified 3D model in Rhinoceros software. By using various algorithms to correct the mistakes in manual design, this method can provide a complete 3D model considering the congruence of the actual drawing.

In this paper, the development and test stages of an open-source user interface are presented. The developed user interface is compatible with most of the low-cost camera-based spectrometer designs in the literature. The spectrum image of the light source that is acquired with the camera is cropped and analyzed in a real-time thread after interactive calibration which is a special feature of the user interface. Camera controls (such as brightness, contrast, saturation, exposure and etc.) are also available through the user interface. For user interface testing, a common spectrometer design that is composed of a light-guide tube with a narrow entrance slit in one end and an image sensor on the other is constructed. Various compact fluorescent lamps and light emitting diodes are applied as light source and the results are presented. Developed cross-platform user interface can be used with lowcost spectrometer designs especially involving a web camera.

python's naming convention provides suggestions on naming style, but these suggestions are not always clear for beginners who struggle to understand the usefulness of the conventions. In this research, we studied two properties that affect naming, namely, name-length and style. We analyzed python code from five professional project libraries and compared the name statistics with those obtained from student code. Our results show that, compared to students' work, expert developers use longer names (more descriptive) and are more closely compliant with the existing python naming convention. This research provides specific recommendations on the length and style of naming integers, floats, data structures, functions, function arguments and classes for students of python.

A new High Entropy Alloy (HEA) in the ZnGaCu-(AuSn) system was designed to join skutterudite thermoelectrics (CoSb2.75Sn0.05Te0.20), with a diffusion barrier of Ni applied, to Cu. Such a joint could be part of a device for thermal energy recovery within automotive exhaust systems. A rapid large-scale screening calculation technique based on python programming has been introduced to conduct the HEA selection process, resulting in a series of alloys, which have been experimentally verified. It is demonstrated that a particular ZnGaCu-(AuSn) HEA alloy can join Ni and Cu successfully;a good joint is formed, and the average electrical contact resistance of the interfaces after joining is promising at room temperature, which shows that it has the potential to improve on the existing fillers used in such applications. The alloy design methodology used here suggests a potential efficient route to design new filler metals for a wide array of applications in which existing filler metals are not suitable.

In recent years, RPA has been widely used to automate office work. In this study, we use this RPA for playing digital games. The purpose of this research is to utilize the programming techniques used in RPA for game play as teaching materials for programming. As a first step, we examined what areas of programming learning would be possible with gameplay RPA. In recent ICT environments, programming of images and sounds frequently occurs. There are also many opportunities to use Web API and machine learning libraries. We think that it is necessary to create new teaching materials in response to changes in the programming environment. Gameplay RPA will also have a great effect on raising the motivation for learning.

Brief overview of the Serbian IT sector employment situation is given. Through the summary of the past online learning experiences it is shown that online learning can be an effective tool to reeducate the Serbian workforce to serve the countries growing IT employment demands. The nature of the UN Development grants in Serbia is explained together with the details of the joint proposal from the University of San Diego Extension and the Mathematical Institute of the Serbian Academy of Sciences and Arts. The proposal consisted of a group of Java and python courses that were delivered online in English to 34 students selected from more than 80 people that applied. The results presented show that the program was very effective with an extremely high satisfaction rate both in terms of the content and online delivery platform, and that the similar methods can be used in the future for further education of the IT workforce.

This paper presents the use of neural networks to detect people with anti-virus masks. The algorithm allows to determine if a person has a correctly worn mask (covered nose and mouth). The use of neural networks has been compared with typical Haar cascade frontal face solutions available in the OpenCV library. The proposed solution has been checked for efficiency and precision, as well as for the minimum resolution requirements of the resulting facial image. The software works on still images as well as on video sequences from computer webcams and CCTV cameras.

The Culturo-Techno-Contextual Approach (CTCA) is a teaching method based on culture, technology, and context to ease difficulties in students' understanding of concepts. python programming as a concept in computer studies is difficult for students to understand at the secondary school level. This study investigates the efficacy of the CTCA in understanding python programming in the Nigerian computer science education curriculum. This study adopts a quantitative approach. Analysis of covariance procedure is applied to the data with pretest scores inserted as the Covariate. The results show that the experimental group significantly outperformed the control group. Thus, our findings reveal a statistically significant difference in academic achievement in python programming of students taught using CTCA and those taught using the lecture method, regardless of gender. The novelty of this study is hinged on the testing of a cultural teaching method in easing the difficulties relative to the study of python programming. This study, therefore, provides empirical evidence for the adoption of the CTCA in computer education.

Transport demand modeling is a crucial stage to be implemented for a variety of optimization techniques in the field of transportation management. The paper describes the model for simulations of demand for goods’ deliveries by cargo bicycles in the area with the restrictions of motorized traffic. The proposed model is based on the classical four-step approach with additional procedures for generations of demand as the flow of requests for cargo deliveries. The paper presents the case study of the demand generation in the Old Town district of Kraków city: the obtained simulation results are characterized by high adequacy. The simulation model, implemented in python programming language, can be used as the main tool for solving optimization problems, such as the localization choice for loading points or substantiation of the number of cargo bicycles used for deliveries in the region.
