Intelligent Multi-Modal Monitoring Framework for Birds in Forest Ecosystems and Zoo Animals through AI, CCTV, IR, and Drone Surveillance
No full textBirds are indispensable bioindicators for evaluating environmental health, however, the continuous monitoring of specific species in forests is often hindered by low visibility, seasonal changes, and the activity of nocturnal animals. To overcome this, we suggest an AI-based solution that utilizes smart CCTV integrated with infrared (IR) imaging for remote observation 24/7. The system utilizes a dual-camera arrangement combined with motion triggers, behaviour-based positioning, and deep learning models that are trained for recognition under different light conditions. The monitoring during the day is done using CCTV, whereas the IR cameras are capturing the thermal signatures at night; these cameras are placed in strategic locations near nesting, drinking, and migration areas. Species recognition, population counting, and behavioural trend analysis are done through real-time data processing during the different seasons. Making an extension of this framework, we have a proposal for a drone-based system for monitoring zoo animals where drones will record only when there is motion detected to save storage, with videos uploaded to the cloud for further analysis. Using this system, accurate counts of animals, disease and distress detection, and monitoring of individuals hidden by plants or terrain can be achieved. Such AI-powered detection combined with smart surveillance and cloud management allows the system to be a scalable and low-cost solution for both biodiversity conservation in forests and welfare management in zoos, thereby creating a better protection framework for rare and endangered species
Modéliser une situation de triage en accès direct : une traduction didactique du raisonnement clinique en kinésithérapie
No full textContexte : L’accès direct en kinésithérapie, autorisant la consultation sans prescription médicale, transforme les responsabilités professionnelles des kinésithérapeutes. Cette évolution requiert une capacité de triage fondée sur le raisonnement clinique, articulant sécurité du patient et autonomie décisionnelle. Objectif : L’objectif de cette étude est de modéliser la structure conceptuelle de la situation de triage mobilisant le raisonnement clinique en accès direct pour une consultation en raison d’une lombalgie. Cela permettra de mieux comprendre les processus décisionnels des kinésithérapeutes et d’en permettre la traduction didactique. Méthode : Une étude qualitative de type ethnographie ciblée a été menée auprès de kinésithérapeutes expérimentés. Chacun des cinq participants a réalisé une consultation simulée en accès direct pour lombalgie avec une patiente standardisée, suivie d’un entretien d’auto-confrontation. Les données ont été analysées selon une approche thématique mixte (déductive et inductive). Résultats : Cinq thèmes principaux émergent : émotions (responsabilité, frustration), processus de raisonnement (analytiques, non analytiques, interactifs), concepts organisateurs de l’action (douleur, anamnèse, contexte), et moments clés de décision (repérage des indices, fixation d’objectifs, catégorisation pour l’action). Ces éléments composent une structure conceptuelle de situation permettant de situer la décision sur une échelle de préoccupation, menant à un diagnostic kinésithérapique d’inclusion, d’exclusion et/ou d’orientation. Conclusion : Cette structure conceptuelle formalise les schèmes implicites du raisonnement clinique en accès direct et constitue une ressource didactique pour la formation et la supervision clinique. Elle favorise la transformation des savoirs professionnels tacites en savoirs enseignables et contribue à rapprocher travail réel et travail prescrit
Integration of photogrammetry data and 3D modelling GIS for analyzing spatial utilization intensity based on Jambi city government regulations in sustainable spatial planning (Case study: Pasar Jambi Sub-district)
No full textIncreasing urbanization in metropolitan areas has led to the emergence of many densely populated areas and illegal buildings [1]. To control this growth, local governments have made various efforts to control the intensity of development or land use. This study evaluates spatial utilization intensity in Pasar Jambi District to address the challenges of rapid urbanization and the proliferation of non-compliant structures. By integrating 3D photogrammetric modeling and Geographic Information Systems (GIS), the research assesses the compliance of Building Coverage Ratio (BCR), Floor Area Ratio (FAR), Green Coverage Ratio (GCR), and Building Setback Lines with Jambi City Regulation No. 3/2015 and Draft Regulation No. 5/2024. The findings indicate that spatial utilization in the study area remains suboptimal, characterized by excessive BCR, deficient GCR, and frequent setback violations, which effectively "lock" land resources and hinder functional adaptation. Conversely, FAR values generally remain below the maximum allowable thresholds, suggesting significant potential for controlled vertical intensification. Shifting urban growth from a horizontal to a vertical trajectory is recommended to alleviate pressure on land availability and ensure the implementation of sustainable spatial planning
Analysis of a Single Squared Wingsail Design as an Auxiliary Propulsion System on a Tanker Ship
No full textThis study presents an analysis of a single squared wingsail used as an auxiliary propulsion system for an 8,700 DWT oil tanker. The objective is to evaluate the aerodynamic performance and stability feasibility of the wingsail and to assess its contribution to engine power reduction. Numerical simulations were conducted to obtain lift and drag coefficients for three aspect ratios (AR 2, 4, and 6) with a constant sail area of 289 m2. Stability assessment was performed at multiple voyage waypoints along the Gresik–Bontang round trip using the weather criterion (K ≥ 1) and metacentric height (GM ≥ 0.3 m). The results indicate that all configurations satisfy the stability requirements, while AR 4 provides the most effective performance in terms of thrust generation and power reduction. The AR 4 configuration, with a span of 34.0 m and a chord of 8.5 m, achieves the highest average engine power reduction of 5.3%, compared to 4.9% for AR 2 and 4.1% for AR 6. These findings demonstrate that the selected wingsail configuration is aerodynamically effective and stable, offering a practical solution for auxiliary wind-assisted propulsion on tanker vessels
Smoothed Particle Hydrodynamics Simulations of Wave Run-Up over Hexaloc Armour on Rubble-Mound Breakwaters
No full textIndonesian beaches are increasingly vulnerable to abrasion and erosion, requiring reliable protection such as breakwaters. Since crest freeboard determines the level of safety, wave run-up predictions must be accurate. This study evaluates run-up on a 1:2 rubble-mound breakwater slope armored with Hexaloc using SPH (DualSPHysics) to improve design accuracy and efficiency. The geometry was constructed in AutoCAD and SketchUp. The simulation covered wave heights of 0.05–0.13 m, periods of 1.1–1.5 s, and single-layer and double-layer armor configurations. The numerical results were validated against analytical–empirical formulations, particularly the Ahrens relation. Ru/H increases with rising Iribarren number and then tends to plateau at high values. SPH produces Ru/H 0.538–1.076 (single-layer) and 0.588–1.216 (double-layer), while theoretical predictions are higher: 1.616–2.299 and 1.59–2.30. In the test range, single- and double-layer Hexaloc produced comparable run-ups; two layers were equivalent or slightly higher. The SPH–Ahrens fit was highly linear (R2 = 0.9999 single-layer; 0.9948 double-layer), but SPH still predicted lower Ru/H than Ahrens
Comparing Chinese and European Adolescents: A Cross-Cultural Analysis of the Impact of Virtual Community Participation
No full textThe way that the younger generation communicates has been influenced as they are more accessible to the internet. Both Chinese and European adolescents start to participate in online groups and communities regardless of their cultural backgrounds. This study investigates how social cognition and group identity of Chinese and European adolescents are influenced in virtual community participation, and illustrates the impact on social cognition and group identity among these groups. Based on social identity theory and computer-mediated communication theory, this study examines the differences in psychological patterns and motivations between Chinese and European adolescents when they participate in the online community. Several factors, such as seeking emotional support, developing social skills and expressing self-identity, are highlighted in this study. However, the risk of cognitive bias and the decrease in offline interaction need to be considered. A diverse cultural background is the core factor resulting in different participation. For instance, Chinese adolescents tend to seek social interaction in online communities, but European adolescents are likely to express themselves. Moreover, this research provides practical implications for promoting adolescent mental health and cross-cultural communication
A Modified H-Bridge 25 level Inverter with only 11 Switches to improve the sinusoidal nature of the output to enhance the performance of Inverter fed AC loads
No full textThe idea of a multiple inverter originated from the extension of inverters to many layers in order to lessen distortion from the basic sinusoidal waveform. Using multiple level inverters has the drawback of requiring the installation of extra switches, which raises the system’s bulk and cost and reduces its reliability due to the higher component count. This study proposes a twentyfive-level inverter (25-LI) with fewer switches to address the issue of the system being bigger, more expensive, less dependable, and having less distortion than a symmetrical H-bridged 25-level inverter. The MATLAB platform is used to develop the idea, and analysis is used to evaluate the results’ effectiveness
The Impact of Psychological Resilience of Left-behind Children in Chinese Junior High Schools on Their Learning Motivation and Coping Strategies
No full textThis study discusses learning motivation among left-behind junior secondary students in China. It uses a literature review of 14 peerreviewed English articles. It analyses how left-behind students’ psychological resilience and the environment they live in influence their learning motivation. Much research shows that left-behind students have lower motivation than non-left-behind students, and this pattern is linked to anxiety and a weakened self-concept. Research also indicates that support from schools and families can substantially improve left-behind students’ motivation. At the school level, a positive phenomenon and strong relationships between teachers and students and among peers can significantly enhance their learning motivation, and teachers’ emotional and academic support plays an important moderating role. At the family level, parental expectations and high-quality interactions between parents and children can foster their educational aspirations and self-efficacy, which indirectly strengthen learning motivation. Based on these findings, this article recommends joint efforts by schools and families: build supportive classrooms and strengthen home–school communication at the school level, and provide sustained emotional and learning support at home, together to promote the sustainable development of learning motivation among leftbehind junior secondary students
Optimal integration of Distributed Energy Resources using a sensitivity-Based GEPSO Approach in Distribution Networks
No full textThe growing energy demand has highlighted the need for reliable, decentralized, and self-sustained power systems. In this context, optimal integration of distributed energy resources (DERs) into distribution networks is vital for improving voltage stability and reducing power losses. However, conventional DER planning methods are computationally intensive and may produce inconsistent solutions under varying load conditions. This paper presents a sensitivity-based Generalized Particle Swarm Optimization (GEPSO) framework for optimal siting and sizing of DERs in radial distribution systems. The methodology is implemented in two stages. First, site-specific geographical and meteorological data are evaluated to determine realistic DER capacity limits. Second, these feasibility constraints are embedded within the GEPSO algorithm to identify optimal DER locations and sizes. Load flow analysis is performed using the forward–backward sweep method on a real 69-node Ramchandrapura feeder and the IEEE 33-node test system under multiple loading and DER penetration scenarios. Simulation results demonstrate an average active power loss reduction of approximately 36%, with up to 3.3% improvement compared to conventional PSO, while enhancing the minimum bus voltage by about 3–4%. The key contribution of this work is the integration of site-specific feasibility assessment with a sensitivity-guided GEPSO framework for efficient DER planning applications
The effect of ballistic stretching and passive stretching on increasing hamstring muscle flexibility in futsal players
No full textFlexibility is the ability of muscle tissue to extend maximally so that the body can move with full ROM without pain and resistance. Good hamstring flexibility is able to contract concentrically and eccentrically with maximum ROM. This study is a pretest-posttest one group design. The population consisted of 27 people where 26 people were taken as samples by being given treatment in the form of Ballistic Stretching and Passive Stretching. Measurements were taken using the sit and reach test. Based on the paired t-test in the treatment group, the results of the Paired T test of hamstring muscle flexibility showed a significance value = 0.000 or (p < 0.05), which means that there is an influence of independent variables on related variables, namely the provision of ballistic stretching and passive stretching to increase hamstring muscle flexibility. Ballistic stretching and passive stretching have an effect on increasing hamstring muscle flexibility in futsal players
