The flag effect on the physical performance of soccer assistant referees

The aim of the study is to compere the performance of the assistant referee without and with the flag, based on existing and novel tests. Introduction: Millions of fans around the world are invested in the game of soccer, cheering on their favorite team, practicing their skills in the park, or simply watching from afar via the media. As such, fairness in refereeing is of the utmost importance, regardless of the level of game or the teams who are playing. The refereeing team plays a critical role in enforcing the rules of the game and ensuring fair play on the field. In addition to working together in the utmost coordination, the referee, two assistant referees, and the standby official are required to oversee the entire match, while making crucial decisions in split seconds. In addition to their verbal communications, assistant referees must carry and use their flag throughout the game, as means for signally their decisions. When running along the sideline, assistant referees hold the flag in opposite hand to the direction in which they’re moving at that time – resulting in up to 30% of their movements during the game being sideways movements. Testing and comparing the athletic abilities of assistant referees is therefore an essential component in ensuring the accuracy and fairness of soccer matches. Assistant referees play a critical role in enforcing the rules of the game, and their ability to run quickly and accurately while holding a flag can have a significant impact on the outcome of the performance. Participants: 18 assistant referees (two female) who are on the staff of the National League in the Israel Soccer Association. The participants’ mean (±SD) variables were as follows: age=29yrs (±3.4); height=178cm (±0.06); weight=68.22kg (±10.45); fat percent=14.67% (±4.86); and seniority on the league=3.11yrs (±1.45). Results: Show that in all the tests the performance was significant better without the flag (RST, agility test and linear speed), the performance decrement % (RST), show no significant result, P<0.05, t (0.91) = 17. Conclusions: the referee run faster without the flags but the no deferent in the fatigue, so they have to train and testing with flags like in the game.

The Impact of Design Factors on User Behavior in a Virtual Hospital Room to Explore Fall Prevention Strategies.

Falls in hospitals pose a significant safety risk, leading to injuries, prolonged hospitalization, and lasting complications. This study explores the potential of augmented reality (AR) technology in healthcare facility design to mitigate fall risk. Few studies have investigated the impact of hospital room layouts on falls due to the high cost of building physical prototypes. This study introduces an innovative approach using AR technology to advance methods for healthcare facility design efficiently. Ten healthy participants enrolled in this study to examine different hospital room designs in AR. Factors of interest included room configuration, door type, exit side of the bed, toilet placement, and the presence of IV equipment. AR trackers captured trajectories of the body as participants navigated through these AR hospital layouts, providing insights into user behavior and preferences. Door type influenced the degree of backward and sideways movement, with the presence of an IV pole intensifying the interaction between door and room type, leading to increased sideways and backward motion. Participants displayed varying patterns of backward and sideways travel depending on the specific room configurations they encountered. AR can be an efficient and cost-effective method to modify room configurations to identify important design factors before conducting physical testing. The results of this study provide valuable insights into the effect of environmental factors on movement patterns in simulated hospital rooms. These results highlight the importance of considering environmental factors, such as the type of door and bathroom location, when designing healthcare facilities.

Dynamic characteristics of the sideways movement of pedestrians: An experimental study based on single-file experiments

In this paper, we investigate the dynamic characteristics of the sideways movements of pedestrians toward the left-hand side and right-hand side through a set of single-file experiments. We find that the velocities of pedestrians during sideways movement periodically fluctuate, and the corresponding spatiotemporal diagram of pedestrian movement exhibits a jagged pattern. In addition, by analyzing the fundamental diagrams, we find that the velocity and flow of the sideways movement toward the right-hand side are greater than the velocity and flow of the sideways movement toward the left-hand side at the same crowd density. By further exploring step frequency/step length-headway relations in rightward and leftward sideways movements, we find that the greater velocity observed in rightward sideways movement is primarily attributed to its higher step frequency. Finally, we systematically compare the dynamic characteristics of pedestrians when they move forward, backward, and sideways toward the left-hand side or right-hand side. Our comparison results indicate that among these four movement modes, the free speed and maximal flow rate of pedestrians in the sideways movement toward the left-hand side are the lowest. These findings provide new insights into pedestrian flow dynamics.

Design and Development of AKEA: A 360-degree rotating vehicle

The design of a 360-degree rotating vehicle has been proposed as a solution to the problems encountered in traditional wheel vehicles. This paper highlights the benefits of such a design, the proposed models for implementing the design, and the design of a 360-degree rotating vehicle known as AKEA. Traditional wheel vehicles are faced with numerous problems such as parking and u-turn. The 360-degree rotating vehicle design eliminates these problems as it can take turns without moving the vehicle, and no extra space is required to turn the vehicle. The proposed models for implementing the design of the 360-degree rotating vehicle include lifting plates, chain sprockets, chain or belt drives, and quad-steering mechanisms. These models have several shortcomings, including complexity in design, unrealistic features and increased turning radius. The AKEA design, however, incorporates sustainable and recycled materials, and the result of the design process was a vehicle that performed various features. These features include side-ways movement, 360-degree rotation, and mobile phone operation. AKEA is connected to the mobile phone via Bluetooth, having a range of 100 meters. However, to improve the design further, sensors for self-driving and WiFi connectivity for a broader range of connectivity were proposed. In conclusion, the design of a 360-degree rotating vehicle is necessary to reduce and eliminate problems encountered in traditional wheel vehicles. Although several models have been proposed, the AKEA design performs various features and can be implemented in modern cars and trucks. Improving the design by incorporating sensors and WiFi connectivity will improve the responsiveness of the mobile application and ensure wider range connectivity.

Analisis Efektivitas Daya Dan Energi Pada Sistem Pembersih Solar PV 2 × 50 Wp dengan Metode Lateral Movement

The implementation of the solar cell itself often has problems in its operation. One of the factors that affect the performance of PLTS is that the dirty solar panel cover glass is covered with dust or dirt so that it blocks the intensity of sunlight entering the solar panel which results in a reduced output of the solar panel. A 2x50 Wp solar pv cleaning tool was made to overcome the problem of reduced solar pv output due to the influence of dirt adhering to the pv cover glass. The cleaning tool that has been designed is expected to maximize the quality of power and energy that will be generated by solar pv. The solar pv dirt cleaning tool is used on the research object of the PLTS system in the Renewable Lab, Navy Building, State Polytechnic of Malang. Making a cleaning tool design using Solidworks software, with the reason being able to get a 3D picture of the planned pv dirt cleaner. The cleaning tool works with the help of a battery/power supply as its electrical power. There are 3 dc motors connected to brushes, wheels and water pumps. The cleaning tool moves in a lateral movement (sideways movement) from corner to corner 3 times, then the brush rotates to clean the solar cell cover glass from dirt. In the cleaning process, it can be assisted by using water provided and sprayed by a water pump. The average Vmp and Imp values are 19.72 V and 1.64 A. From the Vmp and Imp values, the average Pmp calculation results are 32.60 W for solar pv after cleaning. Before cleaning, the average maximum voltage (Vmp) and maximum current (Imp) values are 18.43 V and 1.05 A. From the Vmp and Imp values, the average Pmp calculation is 19.65 W.

Perancangan Vertical Axis Twin Turbine Pada Pembangkit Listrik Arus Laut Di Suramadu

Renewable energy sources are environmentally friendly energy sources that do not pollute the environment and do not contribute to climate change and global warming as in other traditional sources. Ocean currents are the movement of seawater masses from one place to another either vertically (upward motion) or horizontally (sideways movement) towards equilibrium, or the very wide movement of water that occurs throughout the world's oceans. In this study using experimental research where the maximum ocean current speed results in pile 56 were only 1.28 m / s, the turbine will need a greater speed to beat the initial torque of the 5 kW generator. The results of the 12-day test showed that the speed of the ocean current at Suramadu Bridge pile 56 ranged from 0 - 70 cm/s and only 1 week with a maximum ocean current speed, which was 128 cm/s. When using a 5 kW generator, it is likely that the generator will rotate and generate electric current for only a week. Beyond that the generator does not rotate because the speed of the ocean current is low. Therefore, the condition that the initial torque is obviously smaller than 10 kW in the twin turbines installed 3 generators each are 3.5 kW so that the turbine is still able to rotate at low current speeds such as the speed of ocean currents in Suramadu and generally Indonesian waters.

3D МОДЕЛЮВАННЯ ПРОЦЕСУ МАНЕВРУВАННЯ ЧОТИРИВІСНОГО КОЛІСНОГО ШАСІ З ДВОМА ПОВОРОТНИМИ ПЛАТФОРМАМИ

One of the ways to increase the maneuverability of the wheeled vehicles of the National Guard of Ukraine is to use a four-axle wheeled chassis with two turntables, which will allow the machine to turn with the smallest radius, move crab, sideways and turn around its own vertical axis. The creation of such a chassis is associated with a large amount of various experiments and tests of the finished sample. The development of computer technology and technologies has led to the creation of software applications for computer (simulation) modeling, which allow research and study of the properties of technical objects and systems under different conditions. The article developed a digital model of the chassis of a four-axle machine with two turntables and identified its features. For modeling, a powerful package of solid modeling Autodesk Inventor was chosen, which provides a comprehensive flexible set of tools for 3D design, visualization, instrumentation, analysis and calculations. When building a general 3D model of the chassis, the main features of the layout of parts and assemblies of this wheeled vehicle were taken into account. The forced rotation of the wheels and the rotation of the platforms were modeled by entering the value of a single parameter or setting using a graph. Depending on the needs of the experiment, graphs were set for displacements, speed or acceleration. In the course of a visual experiment, a simulation of the maneuvering of a four-axle vehicle was carried out for three options: turning the chassis to move in the opposite direction; changing the direction of movement through the turn of the chassis is a difficult maneuver; turning the chassis for sideways movement. The analysis of virtual studies showed that the control of the front, rear or both turntables is a promising way to increase the maneuverability of wheeled vehicles. In addition, the created computer prototype allows you to determine the main characteristics of the future product, carry out analysis, upgrade and necessary modification, set the desired trajectory of movement, including when passing through obstacles.

Analytical calculation of the vessel maneuver «sideways movement» parameters

A boatmaster must be well aware of the manoeuvrability of his vessel as well as the ability of the ship's controls to perform a manoeuvre. In the "Information" on maneuvering parameters, which is available on the ship, there is no data on the performance of such an important maneuver as "sideways movement," which is often used in the performance of mooring maneuvers in a cramped water area. In the work, having made some assumptions, the solution of the system of equations of movement of the vessel in relation to the considered maneuver is given. The author has obtained analytical expressions for calculating the speed and distance traveled by the vessel according to the time of the "acceleration" maneuver, inertia movement and active suppression of the speed of movement. Using the obtained expressions, the parameters of the "sideways movement" of the motor ship of project 507 were calculated. Graphs of the dependence of the speed and distance traveled by the vessel on the maneuver time are given.

Middle fins hold the key to fish movement

Next time you find yourself in an aquarium, pay attention to the fish's fins. The middle fins in particular show a mesmerising variety in number, shape and position on the fish's body. But what is the purpose of such a variation? David Matthews and George Lauder of Harvard University aimed to address this question by investigating the interactions between the middle and tail fins and their effect on a fish's movement. Biologists and engineers have previously attempted to navigate these tough waters, so what new angle did the pair introduce?Matthews and Lauder used a simplified fish-like robotic model: a thin plastic foil mimicking the proportions and form of a fish (a fish body, a tail fin and two middle fins symmetrically arranged on either side of the body) connected to a robotic flapping device introducing a sideways movement with the help of motors. This model was a step closer to real fish than previous mechanical models, in which just the forces produced by the fins were investigated. On top of that, they decided not to control every aspect of the fish's movement, which would overcomplicate the robot-fish, but measure them instead. They attached a force-sensing rod to the front of the foil, where the fish's head would be, and changed the number of flapping cycles the body experienced per second to propel itself forward. Using this setup, they could quantify the foil's energy and movement such as its speed and the maximum amount each model fin flaps respectively, all together determining the swimming performance of this model fish.With the robot-fish at hand, the authors first asked how the position of the fish's middle fins and the timing of their flapping, i.e. whether they flap in unison with the tail fin or not, affect its movement. They performed experiments with four types of robot-fish: flexible or stiff, and with middle fins near or far from the tail. They then showed that the number of flapping cycles per second has the largest effect on the fish's swimming performance, which is consistent with live fish that flap their fins more often when they want to accelerate. The modelling also revealed that the stiffness of the foil didn't significantly change its movement while the location of the middle fins did. The far-fin foil was always the fastest, and when the middle fins were moving out of sync with the tail fin, it was also the most efficient. The team also observed that the out of sync flapping of the fins was beneficial for force production, which varied less over time, costing less energy for the fish.To understand these results further, Matthews and Lauder used a visualisation technique to look at the water flow around the fins. They showed that having middle fins is helpful as their flapping results in a strong side-to-side flow at the front of the tail fin – irrespective of the fin position in flexible foils. In contrast, they found that for the stiffer foils, the one with the far middle fins resulted in a direct interaction of its flow with the front of the tail fin, amplifying the production of the propelling force. Thus, they were able to conclude that the patterns of flow amplification are consistent with their statistical model and can help explain why fin position and flapping timing affect force production. As a result, while we previously knew that flow from one fish's body can impact swimming performance in following individuals, we now also know that following fish can independently improve their performance using their secret weapon – middle fins.

Behavioural and electrophysiological responses of Liothrips jatrophae (Thysanoptera: Phlaeothripidae) to conspecific extracts and some of its identified compounds

AbstractThis study investigated the behavioural and electrophysiological responses of the thrips Liothrips jatrophae to conspecific extracts and some of its identified compounds. We integrated four constituents of the insect's chemical communication: identification of the compounds from L. jatrophae extract, behavioural response to extracts and synthetic blends, morphology of the main olfactory receptors (antennae), and electrophysiological response of the main olfactory receptors of the antennae to extracts and to individual synthetic compounds and synthetic blends. Analysis by GC–MS revealed that the L. jatrophae extract contains a mixture of 11 compounds (perillene, tridecane, β‐acaridial, tetradecane, pentadecane, heptadecane, heptadecene, dodecyl isobutyrate, tridecyl isobutyrate, tetradecyl isobutyrate and hexadecyl isobutyrate). The major compounds were tridecane, pentadecane, tetradecyl isobutyrate and hexadecyl isobutyrate. When the thrips were exposed to the extracts, they exhibited an escape response, accompanied by other behavioural responses, such as rapid sideways movement and lifting of the abdomen and secretion of a drop at the tip of the abdomen. Morphology and distribution of the L. jatrophae antennal sensilla were examined with a scanning electron microscope (SEM). The antenna consists of a scape, pedicel and six flagella. The microphotographs showed two types of sensilla: basiconica and trichoidea. Single sensillum recording (SSR) showed that the sensilla basiconica located in segment IV of the antenna were the most sensitive to the L. jatrophae extracts and to a synthetic blend, whereas the sensilla trichoidea did not exhibit electrophysiological response.

Prediction of buckling force in hourglass-shaped specimens

It is important to avoid buckling during low-cycle fatigue testing. The buckling load is dependent on the specimen shape, material properties, and the testing machine. In the present investigation of hourglass-shaped specimens the importance of the diameter to radius of curvature is examined. Diameters of 5 and 7 mm are examined with a ratio of radius of curvature to diameter of 4, 6, and 8. The machine used is an Instron 8800 with elongated rods for a climate chamber. This leads to a reduced stiffness of the machine during compression testing. A finite element model (in Abaqus) is developed to identify the critical buckling force. For hourglass-shaped specimens, buckling means onset of sideways movement, without a drop in the applied load which is typical for conventional Euler buckling. The onset of sideways movement is identified experimentally by analysis of the data from extensometer and the load cell. This model is verified by experiments and fits within 0.6 to − 11% depending on the specimen diameter and diameter to radius of curvature ratio. The smallest deviations are obtained for the 7-mm-diameter specimen with deviation varying from 0.6 to − 3.3% between the model and the experiments. The current investigation is done with a commercially available hot rolled structural steel bar of Ø16 mm.

Design of Robotic Motion Platform Utilizing Continuous Contact Skating

Abstract The continuous contact-based skating technique utilizes the sideway movement of the two skates while changing the orientation of the two skates simultaneously. The skates remain in contact with the surface. A mathematical model mimicking a continuous skating technique is developed to analyze the kinematic behavior of the platform. Kinematic and dynamic equations of motion are derived for the nonholonomic constraints. Heuristic-based motion primitives are defined to steer the robotic platform. For the lateral movement of the platform, a creeping-based motion primitive is proposed. A prototype of the robotic platform is developed with three actuated degrees-of-freedom—orientation of two skates and distance between them. A multibody model of the platform is also developed in matlab. Analytical expressions are verified using simulation and experiments. The robotic platform follows the desired motion profiles. The motion profiles include straight-line motion, motion in a circular curve, and lateral creep-like motion of the platform. However, the initial deviation has been observed in both the simulations and experiments due to the slipping of the roller skate at the contact point with the surface. The platform can be effectively used in a structured environment.

Terrestrial slug uses a vertical bridge of mucus to descend rapidly from heights

AbstractAmong the terrestrial slugs, mucus secretions are used for a variety of purposes that typically require the mucus to be excreted from the slug’s foot along surfaces or excreted onto epithelial linings. However, terrestrial slugs are also capable of producing mucus threads that are anchored to surfaces but extended into the open air. These threads are akin to spider silk and may serve as an alternative form of locomotion, allowing for rapid movement between surfaces of different heights. Herein, we report on the production of mucus threads by a terrestrial slug for the first time in Australia, and its possible use as a tethered vertical bridge for locomotion. Field observations revealed a striped field slug, Lehmannia nyctelia, descended from a single thread of mucus that was not only tethered to the top of a fence line but extended in front of the slug to the ground where it was tethered also to gravel. Our observations suggest that slugs produce tethered bridge lines of mucus, over which they can traverse in order to descend from heights. This is in contrast to previous reports of mucus thread production among this and other terrestrial slugs, in which individuals only hang freely from one end of a thread that is attached to a surface above. We suggest that producing a mucus thread that is tethered on both ends may be adaptive by stabilising individuals and preventing excessive sideways movements during descent, particularly when it is windy, which could lead to premature thread breakage.

Ensuring Area Coverage and Safety of a Reconfigurable Staircase Cleaning Robot

Multistorey buildings are rapidly constructing with the current world development. Cleaning of these buildings is a major concern due to several issues such as scarcity of labor. Cleaning robots are developed to cope with these issues. Among these cleaning robots, staircase cleaning robots play a vital role in a multistorey building. Therefore, this paper proposes a control strategy for a reconfigurable staircase cleaning robot to ensure area coverage and safety. A staircase cleaning robot should particularly maintain its orientation parallel to the riser while maintaining a proper clearance with the riser when performing the sideways movement on a thread to ensure safety and coverage. Two Fuzzy Logic Systems (FLSs) have been developed to correct the heading and the clearance distance during sideways movements. Precise measurements on heading error and clearance distance are essential for the decision-making process of the proposed control strategy. Thus, a vision-based perception mechanism has been developed to accurately perceives these essential measurements. The proposal of the control strategy to correct the heading and the clearance distance, and the development of the vision-based perception mechanism are the major contributions of the work. Experiments were conducted by deploying the developed robot in a typical staircase considering different conditions. The experiment results validate that the proposed method can ensure coverage and safety by properly maintaining the heading and clearance of the robot with respect to a riser.

The Inappropriable: On Oikology, Care, and Writing Life

This article thinks epistemological and methodological approaches to work (and to 'work/ life balance') that take deeply into account the choreographic and temporal shifts, the disruptions, the sideways movements of thought, that come with parenting in an economy in crisis. Obliquely rearticulating the 'work/life balance' dyad to better think performative productivity in terms of oikological investments, the article performs another economy of writing and care. Engaged in what I call 'plastic critique,' the article moves and morphs as it proceeds through readings of critical texts in the history of thinking governmentality, care of self, home, and 'contact.' Not only 'performative,' the article also thinks how to enact intimacy within the space of the page, engaging in a method of writing that offers a careful, vulnerable critical praxis. Aware of the current crisis of professional labor in the context of the COVID-19 pandemic, the article takes a longer view of issues of gender and emotional labor while seeking directly to speak through these challenges from a politically situated perspective: within the interstices between moments of work and play. © 2021 Johns Hopkins University Press and SubStance, Inc.

Vehicle oscillation taking into account the rheological properties of the suspension

The forced oscillations of a four-axle vehicle with a double spring suspension are considered. The motion of a system with six degrees of freedom can be represented with sufficient accuracy by a system with two degrees of freedom. Therefore, the body of the vehicle has two degrees of freedom: sideways movement and wagging (jumping and galloping carts will be neglected). It is assumed that the rheological properties of the spring (suspension) are different and obey the hereditary theory of Boltzmann-Volterra viscoelasticity. As the core of heredity, the Koltunov-Rzhanitsyn core is used, which has weakly singular features of the Abel type. Effective computational algorithms for solving problems based on the use of quadrature formulas have been developed. For numerical calculation, a computer program has been compiled, the results of which are presented in the form of graphs. The influence of the rheological properties of the suspension on the forms of vertical and angular movement of the body is studied. It was found that due to the suspension viscosity, the amplitude of vertical and angular oscillations decreases and the frequency increases.

Retro-intraocular Lens Irrigation-aspiration to Prevent Capsular Block Syndrome at the Hands of Novice Surgeons.

Retro-intraocular lens (IOL) irrigation-aspiration is of paramount importance in order to remove the viscoelastic substance from the retro-IOL space and to prevent any early post-operative capsular block syndrome. However, manoeuvring the IOL to reach the retro-IOL space may be difficult at the hands of novice surgeons despite the use of coaxial or bimanual irrigation-aspiration probes. We describe a simpler and safer technique in order to facilitate the removal of this retro-IOL viscoelastic substance using a 26-Gauge bent-cannula mounted on a 2-ml syringe. The fluid is injected forcefully along with sideways movement of cannula in a single-plane to displace the viscoelastic substance.
