Neural Architecture Search for 1D CNNs—Different Approaches Tests and Measurements

In the field of sensors, in areas such as industrial, clinical, or environment, it is common to find one dimensional (1D) formatted data (e.g., electrocardiogram, temperature, power consumption). A very promising technique for modelling this information is the use of One Dimensional Convolutional Neural Networks (1D CNN), which introduces a new challenge, namely how to define the best architecture for a 1D CNN. This manuscript addresses the concept of One Dimensional Neural Architecture Search (1D NAS), an approach that automates the search for the best combination of Neuronal Networks hyperparameters (model architecture), including both structural and training hyperparameters, for optimising 1D CNNs. This work includes the implementation of search processes for 1D CNN architectures based on five strategies: greedy, random, Bayesian, hyperband, and genetic approaches to perform, collect, and analyse the results obtained by each strategy scenario. For the analysis, we conducted 125 experiments, followed by a thorough evaluation from multiple perspectives, including the best-performing model in terms of accuracy, consistency, variability, total running time, and computational resource consumption. Finally, by presenting the optimised 1D CNN architecture, the results for the manuscript’s research question (a real-life clinical case) were provided.

PENGARUH VARIASI LATIHAN SHOOTING AFTER DRIBBLING DAN SHOOTING AFTER PASSING TERHADAP AKURASI SHOOTING PADA ATLET USIA 11-13 TAHUN SSB SOCCER PRATAMA TAHUN 2021

The purpose of this study was to determine the effect of training variants using Shooting After Dribbling Exercises and Shooting After Passing Exercises on Shooting Accuracy in athletes aged 11-13 years SSB Soccer Pranata in 2021. The population of this study were 30 SSB Soccer students, the technique of taking The sample used purposive sampling as many as 10 people with predetermined criteria. The data collection technique is carrying out tests and measurements of shooting accuracy in the form of pre test and post test, namely Shooting After Dribbling and Shooting After Passing. Measurement of the test is done by shooting the target ball that has been determined 5 times and then the results are added up. The results of this study indicate that (1) Shooting after dribbing and Shooting after passing exercises provide a significant increase in shooting results for players aged 11-13 years at SSB Soccer Pratama 2021. It can be seen from the difference in the average ability of students before training. and after exercise. (2) The pretest score of the players in this study was 5.4 while the score of the posttest of the players was 13.8 with t count = 10.1 and ttable = 2.13 so that it can be said that tcount >ttable. So it can be concluded that this exercise greatly affects the shooting ability of players aged 11-13 years at SSB Soccer Pratama on their shooting abilities.

COMPARISON OF THE PERFORMANCE VALUES OF THE U-16 DEVELOPMENT LEAGUE FOOTBALL PLAYERS IN THE COMPETITION PERIOD

This study aims to compare the performance values of U-16 development league football players. The research was carried out according to the experimental research model. A total of 25 football players of a super league football team (age: 16, height: 170,36±7,31cm, weight: 56,89±8,88kg), all competing in the U-16 elite development league, participated voluntarily. The players wear Polar watches on the grass football field; Yo-Yo Intermittent Recovery Level 1 test was applied and aerobic endurance levels, maximal heart rate, and heart rate recovery times were measured. Tests and measurements were applied 1 week before the start of the league. After the first test, the competition period general training program was applied for 9 weeks, 4 days a week, and after that, the same tests and measurements were carried out again. After a 9-week competition training program, there were statistically significant differences in aerobic endurance levels and heart rate recovery times at the 1st minute (p<0.01), no statistically significant differences were found in maximal heart rate and heart rate recovery times at the 2nd minute (p>0.01). In conclusion, it can be said that the 9-week training program applied during the competition period is effective on the aerobic endurance level and heart rate recovery time in the 1st minute. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0893/a.php" alt="Hit counter" /></p>

Diagnostics and Repairs of Damage of the Leaning Tower in Zabkowice Slaskie

The article concerns the diagnosis of the technical condition, as well as the possibilities of renovating, the Leaning Tower located in Zabkowice Slaskie in Lower Silesia, Poland. Damage to the structure of the facility, which occurred in 2015, constituted the basis for carrying out tests and measurements in order to enable the causes of the damage to be determined. The resulting damage is cracks in brick walls. Cracks were formed in the place where the proper structure of the Tower was connected with the staircase constituting the extension of the building. Therefore, it was necessary to carry out diagnostic work. The conducted diagnostic works resulted in the obtaining of knowledge about the technical condition of the facility, and the possibilities of the necessary repair works, which will ensure the further safe operation of the facility. It was considered necessary to stabilize the ground under the staircase by making micropiles. Cracks in the walls were stabilized by making steel ties, rebuilt and reinforced with steel bars. The Leaning Tower, as a historic and unique building in Europe, requires special technical supervision, which will guarantee that it remains in its prime for many years to come and continue to be one of the key tourist attractions of Zabkowice Slaskie.

Influence of orientation of zones of higher hardness of composite layers on their resistance to wear

Purpose: Experimentally substantiate the influence of the orientation of zones of higher hardness on the wear mechanism of contact surfaces. Design/methodology/approach: Forming of variable composition within the working surfaces of parts is a common way to solve the problem of uneven wear. The tests were aimed at determining the characteristics of the layers surfaced with the orientation of the zones of high hardness. For this different tests and measurements were done. Before the test, samples of 45 steel were surfaced with a preliminary application of titanium carbide paste. Findings: As a result of researches it was found that different ways of the orientation of zones of higher hardness have different influences on the characteristics of a surface. The main conclusion is that the transverse orientation of such zones helps to increase the wear resistance of the surface and to save its original relief. Research limitations/implications: The roughness, wear resistance, zonal hardness, and relief of layers surfaced with the orientation of zones of higher hardness were studied. Practical implications: The results obtained are useful in the field of rolling production and mechanical engineering to avoid the uneven wear of parts and as a result to extend the term of their exploitation. Originality/value: In this paper the model concepts of wear process of surfaces with variable composition and measurements of characteristics of surface considering its local hardening are proposed.

Long Distance Dual SpO2 Monitoring in Premature Babies Via Bluetooth Communication

Monitoring the baby's health status is very important, especially for babies born prematurely. Oxygen saturation levels in newborns are very important to know because when the oxygen saturation levels in newborns are low, it is necessary to watch out for hemodynamic abnormalities in the baby. Measurement of oxygen saturation levels in newborns can help detect congenital abnormalities in infants early. This study aims to design an equipment system to continuously monitor the condition of oxygen saturation in newborns. Where in this discussion a monitoring tool is used to monitor 2 premature babies in a baby incubator simultaneously using a Neonatal Fingertip sensor. The system will display the oxygen saturation (SpO2) value and signal. Monitoring on this tool is done wirelessly using the HC-05. Based on the results of tests and measurements in 5 different patients with a pulse oximeter comparison, the difference value of 1% in each patient's results was obtained. The results of this study will greatly help facilitate the work of paramedics in monitoring the vital conditions of newborn babies.
