Analyzing the Tensile Strength of Carbon Fiber-Reinforced Epoxy Composites Using LabVIEW Virtual Instrument

Carbon fiber-reinforced polymer composites are widely used materials in the aircraft industry, automotive sector, marine applications, civil engineering, and daily consumer goods, due to their superior mechanical properties at a relatively low density compared to metallic materials. The studied composites are composed of an epoxy resin matrix in which three layers of carbon fiber fabric are embedded, oriented at 0 and 90 degrees. Carbon fiber-reinforced polymer composites were manufactured using the Vacuum Assisted Resin Transfer Molding technique. The tensile failure mechanism in carbon fiber-reinforced polymer composites is an extremely complex phenomenon influenced by numerous factors. This study aims to evaluate the mechanical behavior of carbon fiber-reinforced composites through tensile testing and to compare experimentally obtained results with those calculated using the mixture rule. Additionally, the behavior of the materials under tensile stress was analyzed using the digital image correlation method. Estimating mechanical properties based on the mixture rule is a common practice in the design phase of polymer composites. This study s novelty and originality lie in its anticipation of the tensile strength and modulus of elasticity of the studied composites. This anticipation was achieved using a virtual instrument developed in the LabVIEW graphical programming environment. The experimentally obtained results for the tensile characteristics of the studied materials are suitable for this type of composite. These results were compared with estimates derived from the mixture rule, and the absolute error was determined.

MODEL CHARACTERISTICS OF PHYSICAL FITNESS OF PROFESSIONAL SOLDIERS OF TWO AGE GROUPS

The purpose of the work is to analyze the integration and interaction of various components of the structure of the physical condition of professional servicemen of the military unit of the West Pomeranian Voivodeship. 50 professional soldiers aged 26-30 and 50 professional soldiers aged 36-40 took part in the study. The scope of the study included the registration of 12 parameters of physical (FD) and motor (MD) development. Mathematical analysis of the obtained research results was carried out with the help of statistics and graphics programs Statistics 13.5 and Excel-16. The results show that the age of the two groups of servicemen does not affect the value of the FD indicators. However, in the group of servicemen over 30 years old, the indicators of FD are integrated more strongly. Among the parameters of MD, the biggest changes occurred in the parameters of the 3000 m run and body inclinations in the age group of servicemen under 30 years of age. Studies have shown that most indicators of FD and MD are interrelated and depend on each other. Among the FD indicators, the following indicators have the largest number of strong relationships: BMI, water content in the body (%), ratio of body weight to body surface area (kg/m2) and body surface area (S) in m2. Among the MD indicators in the group of military personnel under the age of 30, the largest number of strong interrelationships is manifested in the parameters of running 3000 m (s), body tilts 2', pull-ups on a high bar. However, in the group of servicemen over 30 years of age, the strongest relationships are observed for the parameters of pull-ups and 2' trunk bends. As a result of factor, regression and canonical analysis, the main factors and information indicators of the structure of the physical condition of military personnel were determined. Models of their interaction were developed and the specifics of the mutual influence of the group of FD indicators and the group of MD indicators were investigated. The MD scores of professional soldiers have a greater effect on the FD scores than the FD scores on the MD scores.

Automated code development based on genetic programming in graphical programming language: A pilot study.

Continual technological advances associated with the recent automation revolution have tremendously increased the impact of computer technology in the industry. Software development and testing are time-consuming processes, and the current market faces a lack of specialized experts. Introducing automation to this field could, therefore, improve software engineers' common workflow and decrease the time to market. Even though many code-generating algorithms have been proposed in textual-based programming languages, to the best of the authors' knowledge, none of the studies deals with the implementation of such algorithms in graphical programming environments, especially LabVIEW. Due to this fact, the main goal of this study is to conduct a proof-of-concept for a requirement-based automated code-developing system within the graphical programming environment LabVIEW. The proposed framework was evaluated on four basic benchmark problems, encompassing a string model, a numeric model, a boolean model and a mixed-type problem model, which covers fundamental programming scenarios. In all tested cases, the algorithm demonstrated an ability to create satisfying functional and errorless solutions that met all user-defined requirements. Even though the generated programs were burdened with redundant objects and were much more complex compared to programmer-developed codes, this fact has no effect on the code's execution speed or accuracy. Based on the achieved results, we can conclude that this pilot study not only proved the feasibility and viability of the proposed concept, but also showed promising results in solving linear and binary programming tasks. Furthermore, the results revealed that with further research, this poorly explored field could become a powerful tool not only for application developers but also for non-programmers and low-skilled users.

Comparative Analysis of PCC and ECMP Methods in Load Balancing Using GNS3 Simulator

Judging from daily activities, human beings heavily rely on the internet for communication purposes. and exchange information using either social media applications or browsers, vonsistently fast internet speeds are incredibly beneficial for performing tasks and activities, particularly for students and professionals. A sluggish internet connection can be frustrating and may lead to interruptions in online activities and tasks if it persists. Hence, this study examines a comparative evaluation of two approaches, Per Connection Classifier (PCC) and Equal Cost Multi-Path (ECMP) in Load Balancing through GNS3 simulation. Load balancing, as a method for evenly distributing traffic loads, and failover, as a backup mechanism when the main connection experiences problems. GNS3 is a graphical network simulator program that can transmit more complex network topologies compared to other simulators, for example Cisco Packet Tracer. The primary aim of this study is to comprehend how efficiently both techniques distribute traffic loads, maintaining smooth internet access, and increasing reliability. The PCC method produces better throughput, delay and jitter compared to the ECMP method, even though it has slightly different values for each QoS parameter. In testing traffic distribution, the PCC method outperforms the ECMP method. The PCC method can distribute traffic evenly across both ISP lines when downloading and uploading data packets. Meanwhile, the ECMP method can only carry out download and upload activities on one traffic path.

A Case Study on the Static Behavior of a Pedestrian Bridge Built with a Steel Pratt Truss Deck Bridge Supported by an Inclined Roller Support

Construction of bridges commonly uses trusses due to their lightweight design, which can endure heavy loads and span large distances. However, there are instances when the supports of these trusses do not lie normally on a horizontal surface. For some, the supports lie on inclined foundations, which is the focus of this study. The main objective of this study is to present the basic theory of plane truss analysis with an inclined roller support using the Direct Stiffness Method (DSM) in comparison to the use of the Graphic Rapid Analysis Software Program (GRASP) to analyze the static behavior of the structure. Furthermore, a case study is conducted to check the effects of inclined supports on a plane truss structure. Based on the results, it was discovered that the introduction of inclined roller supports does have a negative effect on the stability of the structure.

Effects of Gamified Python Programming on Primary School Students’ Computational Thinking Skills: A Differential Analysis of Gender

Computational thinking (CT), as a new future-oriented literacy, has gained attention at the basic education level. Graphical programming is the common way to develop CT in primary students, but this drag-and-drop programming may weaken students’ understanding of programming’s abstract concepts and code logic. Text-based programming approaches can solve the problems faced by graphical programming, but few studies have explored the impact of text-based programming on CT. Therefore, we conducted a quasi-experimental study with 98 6th graders to explore the impact of gamified Python programming on CT. The findings showed that CT skills, as well as abstraction and decomposition, pattern recognition and evaluation in CT sub-skills, were significantly higher with students in the experimental group than in the control group. Furthermore, we found that gamified Python programming enabled boys and girls to reach the same level of CT skills. However, in terms of CT sub-skills, we found that gamified Python programming was more beneficial to the development of pattern recognition and evaluation skills for boys and abstraction and decomposition skills for girls. This demonstrated the effectiveness of gamified Python programming to improve primary students’ CT skills while clarifying the impact of gender and enriching research in the field of text-based programming.

Teaching Robot Skills Through Demonstrations

Robotic arms can be designed to lift defined payloads precisely and these robotic arms are used in operations like pick and place, welding, painting, precise motion, etc. These robots are programmed using high-level programming, teach pendent, or using graphical programming. If there is any change in the task, then it has to be reprogrammed for the new task, and it’s a tedious job. To address this problem this article focuses on the development of a learning model to teach the robot skills through demonstrations to a robotic arm (xArm) by interfacing with the Oak - D camera. The reach of the xArm robotic arm is 700mm and fitted with a two-jaw gripper. The Oak - D camera has some significant features such as depth sensing, AI capability, and real-time processing. The experimental setup consists of xArm, an Oak-D camera, and a camera mount. The installation of a robotic arm is through xArm python SDK, and the setting up of a camera is through DepthAI python SDK. Initially, color template files for block detection are created using color segmentation technique, later camera matches the color template with the real-time image to get the coordinates with respect to the camera view. In the learn mode the blocks are detected and the coordinates are calculated with respect to the camera and then coordinate transformation is carried out to get the coordinates of the block with respect to xArm. This coordinate is matched with feedback from the xArm and the color of the block is logged to learn file. Through this, a learning file is created. In the demonstration phase first, the coordinates of the block are calculated with respect to the camera view then coordinate transformation is carried out to get the coordinates of the blocks with respect to the xArm, now the controller commands the xArm to sort the blocks using the learn file. It can be concluded that the robot arm sorted the blocks in the same order as taught in the learn mode based on color templates and also the robot arm was able to adapt to the changes made in the environment.
