Maintaining natural habitats is crucial for the preservation of insects and other species that indicate environmental changes. However, the Mpanga/Kipengere Game Reserve and its surrounding farmlands are facing disturbance due to human activities, which is putting many wildlife species, particularly larger mammals, at risk. To determine the impact of human activities on butterfly species diversity and abundance in the reserve and its surrounding areas, we conducted a study from November 2021 to October 2023. We collected butterfly data using transect walks and baited traps in two habitat types. Our study yielded 2799 butterfly Individuals ranging in 124 species divided into five families habitat, season, and anthropogenic factors are significant environmental variables influencing species diversity and abundance of butterflies. Therefore, it’s important to protect habitat and dry-season water for the conservation of invertebrates such as butterflies. Our study findings provide essential information for ecological monitoring and future assessment of the Mpanga/Kipengere Game Reserve ecosystem health. 展开更多

The optimal guidance problem for an interceptor against a ballistic missile with active defense is investigated in this paper.A class of optimal guidance schemes are proposed based on linear quadratic differential game method and numerical solution of Riccati differential equation.By choosing proper parameters, the proposed guidance schemes are able to drive the interceptor to the target and away from the defender simultaneously.Additionally, fuel cost, control saturation,chattering phenomenon and parameters selection were taken into account.Satisfaction of the proposed guidance schemes of the saddle point condition is proven theoretically.Finally, nonlinear numerical examples are included to demonstrate the effectiveness and performance of the developed guidance approaches.Comparison of control performance between different guidance schemes are presented and analysis. 展开更多

This paper is concerned with a scenario of multiple attackers trying to intercept a target with active defense.Three types of agents are considered in the guidance:The multiple attackers,the target and the defender,where the attackers aim to pursuit the target from different directions and evade from the defender simultaneously.The guidance engagement is formulated in the framework of a zero-sum two-person differential game between the two opposing teams,such that the measurements on the maneuver of the target or estimations on the defending strategy of the defender can be absent.Cooperation of the attackers resides in two aspects:redundant interception under the threat of the defender and the relative intercept geometry with the target.The miss distances,the relative intercept angle errors and the costs of the agents are combined into a single performance index of the game.Such formulation enables a unitary approach to the design of guidance laws for the agents.To minimize the control efforts and miss distances for the attackers,an optimization method is proposed to find the best anticipated miss distances to the defender under the constraint that the defender is endowed with a capture radius.Numerical simulations with two cases are conducted to illustrate the effectiveness of the proposed cooperative guidance law. 展开更多

Nowadays, security defence of network uses the game theory, which mostly applies complete information game model or even the static game model. To get closer to the actual network and defend actively, we propose a network attack-defence game model by using signalling game, which is modelled in the way of dynamic and incomplete information. We improve the traditional attack-defence strategies quantization method to meet the needs of the network signalling game model. Moreover, we give the calculation of the game equilibrium and analyse the optimal defence scheme. Finally, we analyse and verify effectiveness of the model and method through a simulation experiment. 展开更多

It is generally expected that the Rio de Janeiro 2016 Olympic and Paralympic Games will bring health and social benefits to their host city and to Brazil. This assumption comes from “common sense”, as a logical conclusion arising from the fact that host cities “inspire” and stimulate lifestyle changes. Benefits are also expected on tourism, self-image, architecture and the economy of the country as a whole. But are these expectations real and evidence-based? What parts of these “facts” are concrete and which ones are not? This paper suggests available ways of quantifying positive effects of hosting an Olympic Game, and puts the focus of this approach on the Rio de Janeiro 2016 Olympic Games and their true legacy, seeking scientific certainties. 展开更多

The present study was built upon a previous study on the new generation video game, exergame, in elementary school physical education (PE). The purpose of the study was to examine the effect of exergames on elementary children's in-class physical activity (PA) intensity levels and perceived situational interest over time. The results indicated that students' situational interest dropped dramatically over two semesters, but their PA intensity increased over time. The results showed that boys and girls were equally active in the exergaming lessons, but boys perceived their gaming experiences more enjoyable than girls did. The findings suggest that exergames may be a possible means to enhance PA in PE. However, whether exergaming is a sustainable way to motivate children in PA is questionable. 展开更多

Background:Active video games are a new method for increasing physical activity(PA).Fully immersive virtual reality(VR)is a hardware device on which an active video game can run.Active(video games in)VR(AVR),might increase immersion,game engagement,and moderate-to-vigorous PA(MVPA),thereby yielding greater exercise-related benefits,e.g.,cognitive performance.Methods:We examined the induction of MVPA via an AVR and a sedentary VR(SVR)as well as the effects of VR play on cognitive performance,which was monitored using 2 different methods.Each of 29 sedentary college students attended three 20-min laboratory sessions(AVR,SVR,or control)in a randomized order;during the control session,they sat quietly doing nothing.A fully immersive headset was used for the 2 video game sessions.We monitored and computed participants’PA using hip-wom accelerometers(wGT3 x-bt;ActiGraph,Pensacola,FL,USA)and a heart rate band(Polar H7;Polar,Kempele,Finland).After each session,the participants completed a mnemonic similarity test(MST)to measure recognition memory.They also filled out a motion sickness questionnaire and an abbreviated game experience questionnaire.Results:The AVR session induced a significantly greater heart rate and more time spent in MVPA than did either of the other 2 sessions regardless of the PA monitoring method.AVR elicited greater game experience questionnaire-assessed sensory and imaginative immersion,challenge,and positive affect than did SVR.The mnemonic similarity test recognition score was marginally higher post-AVR session than it was post-SVR session.Conclusion:AVR elicited MVPA without a significant increase in motion sickness and induced a better game experience and better borderline cognitive performance than did SVR. 展开更多

In the realm of aerial warfare,the protection of Unmanned Aerial Vehicles(UAVs) against adversarial threats is crucial.In order to balance the impact of response delays and the demand for onboard applications,this paper derives three analytical game strategies for the active defense of UAVs from differential game theory,accommodating the first-order dynamic delays.The targeted UAV executes evasive maneuvers and launches a defending missile to intercept the attacking missile,which constitutes a UAVMissile-Defender(UMD) three-body game problem.We explore two distinct operational paradigms:the first involves the UAV and the defender working collaboratively to intercept the incoming threat,while the second prioritizes UAV self-preservation,with independent maneuvering away from potentially sacrificial engagements.Starting with model linearization and order reduction,the Collaborative Interception Strategy(CIS) is first derived via a linear quadratic differential game formulation.Building upon CIS,we further explore two distinct strategies:the Informed Defender Interception Strategy(IDIS),which utilizes UAV maneuvering information,and the Unassisted Defender Interception Strategy(UDIS),which does not rely on UAV maneuvering information.Additionally,we investigate the conditions for the existence of saddle point solutions and their relationship with vehicle maneuverability and response agility.The simulations demonstrate the effectiveness and advantages of the proposed strategies. 展开更多

Due to the simple structure, single form and diversified operation of the low-structure materials, the low-structure materials can be modified, combined and operated according to children's thinking ideas and their own wishes, and the creativity of the children is greatly satisfied. However, many people think that waste materials are low-structure materials. Through a period of research and practice, I found that those low-structure materials that are easy to consume, easy to damage and small are not suitable for outdoor activities. Therefore, according to the characteristics of the secondary school classes, I adjusted the idea of material placement in time when carrying out low-structure activities, carefully observed the children's activities, reflected in time, adjusted the educational behavior and relevant areas, and sorted out the types of low-structure materials suitable for children's independent outdoor games. 展开更多

Edutainment,in the kindergarten education stage,emphasizes the game as the basic activity and combines the content of education with the form of the game,thus it also forms the educational method of gamification teaching.Through investigation and analysis,it is found that the current kindergarten game activity design has the problem of improper combination of educational content and game form.The current kindergarten game activity design has problems such as stereotypes,children’s lack of active learning opportunities in activities,teachers’insufficient theoretical understanding,inappropriate teacher guidance methods,and so on.Embodied cognition theory attaches importance to the important role of the body in the development of cognition,provides new guidance for classroom teaching,and opens up a new path for classroom teaching reform.Based on the perspective of embodied cognition theory,the concept of body and mind integration should be adhered to in kindergarten teaching with games as the basic activity,experiential teaching situation should be created,children’s subjective experience should be respected,and games and interactions should be designed to promote children’s physical and mental participation,thus laying a foundation for the realization of children’s individual freedom,autonomy,and all-round development.Therefore,this paper aims at the existing problems in the current kindergarten gamification teaching and discusses the design strategy of children’s game activities based on embodied cognition theory. 展开更多
