Abstract The purpose of this study is to compare recreationally physically active females and males with regard spine, pelvis lower limb joints peak angles in each plane motion during a single leg squat (SLS). second aim investigate the relationship between kinematics SLS depth males. Fifty-eight healthy, young adults performed 5 repetitions right maximal while keeping their balance. Kinematic data were obtained using an optical capture system. At hip, greater adduction internal rotation...

The research paper focuses on investigating the impact of different metrics clustering process in Kohonen networks, also known as self-organized maps (SOM). theoretical foundations including their structure and algorithm operation, are presented. Various metrics, such Euclidean distance, Manhattan cosine distance potential then discussed. Experiments were conducted using Iris dataset constrained to two dimensions PCA.

Human movement analysis is very often applied to sport, which has seen great achievements in assessing an athlete’s progress, giving further training tips and recognition. In tennis, there are two basic shots: forehand backhand, performed during all matches sessions. Recognition of these movements important the quantitative a tennis game. this paper, authors propose using Spatial-Temporal Graph Neural Networks (ST-GCN) challenge above task. shots on basis images obtained from 3D (forehands...

Regarding wireless sensor network parameter estimation of the propagation model is a most important issue. Variations received signal strength indicator (RSSI) are fundamental problem system based on strength. In present paper, we propose an algorithm Bayesian filtering techniques for estimating path-loss exponent log-normal shadowing outdoor RSSI measurements. Furthermore, in series experiments, will demonstrate usefulness particle filter data. The stability this and differences determined...

Traditional dance is one of the key elements Intangible Culture Heritage (ICH). Many scientific papers concern analysis sequences, classification and recognition movements, making ICH data public, creating visualising 3D models or software solutions for learning folklore dances. These works make it possible to preserve this disappearing art. The aim article propose a methodology scanning was developed on basis capturing via an optical motion capture system with full body Plug-in Gait model...

Convolutional Neural Networks (CNN) have achieved huge popularity in solving problems image analysis and text recognition.In this work, we assess the effectiveness of CNN-based architectures where a network is trained recognizing handwritten characters based on Latin script.European languages such as Dutch, French, German, etc., use different variants script, so conducted research, alphabet was extended by certain with diacritics used Polish language.To evaluate recognition results under...

This paper presents the reengineering of Computer Science (CS) curriculum according to market needs. The new ACM-IEEE Computing Curricula 2013 in context changes is presented. Next, situation ICT industry EU, lack specialists and methods acquisition information about required competences as well some results are described. main part this dedicated existing CS using EU funds describes project its implementation.

Patellofemoral pain syndrome (PFPS), the most common source of knee among physically active individuals, is defined as anterior involving patella and retinaculum that excludes other intraarticular peri-patellar pathology. Differences in activation endurance quadriceps components, causing an imbalance forces controlling patellar tracking during flexion extension joint, appear to be commonly reported risk factors for PFPS. The aim this study was determine differences bioelectric activity...

This article presents the performance analysis of a cross-platform mobile application implemented with Xamarin and two native applications for Android iOS platforms. The results concerning time selected activities were compared in order to determine whether tools are worth using development. Native achieved better performance, however some cases approach allows significant development reduction without deterioration user experience.

Purpose Physical activity (PA) is a well-known, simple and effective preventive therapeutic intervention for low back pain (LBP). In spite of the growing interest in active lifestyles its benefits, more needs to be known about relationship between energy expenditure, body mass lumbar-pelvic kinematics during forward bending movement group young asymptomatic people who met PA guidelines. Young can identified as future risk civilisation diseases lumbar-hip considered predictor LBP occurrence....

Frequently the quality of a path returned by pathfinding algorithm is more important than performance that algorithm. This paper presents new algorithm, based on A*, which better suited for use in 3D game engines. The modification was evaluated series comparative tests. standard A* used as benchmark comparisons. changes consist using different heuristic, adding vertex penalties, and post-processing path. A custom-built graphics engine test environment. paths generated are natural choice...

Prolonged sitting may involve several mechanisms that make it a risk factor for low back pain. The aim of this study was to investigate lumbar-pelvic kinematics and multifidus muscle (MF) activity during squatting forward bending in relation the sedentary behaviour physically active students. Sixty-three students were divided into two groups according time spent position day: 'high' (>7 h/day); 'low' (≤7 h/day). Lumbar-pelvic ratios, ranges motion, angular velocities, MF flexion-relaxation...

This paper focuses on the aggregation of two tennis groundstrokes: Forehand and backhand, which are performed in every match training session. Recognition movements is very challenging task. Therefore it important to correctly classify proper patterns various players. kind study may be a part or development player's skills.
