The study was conducted at Batoe 54 Swimming Pool located in Jl.HM Nalim Jagakarsa, South Jakarta. The formulation of this research problem is what is the tourist attraction in the Batoe 54 swimming pool, how to implement the 7P marketing mix strategy in the Batoe 54 Swimming Pool, and why a marketing mix strategy is needed in these destinations. The purpose of the study was to find out the tourist attraction offered by the Batoe 54 swimming pool, find out more about the 7P marketing mix strategy implemented by the Batoe 54 swimming pool, and provide insight into how artificial tourist destinations can increase their competitiveness in an increasingly competitive tourism market. Data collection was carried out by direct observation and interviews with destination managers and several visitors. The research method uses qualitative, with a qualitative descriptive approach. The results showed that Batoe 54 Swimming Pool is suitable for lower middle class visitors because the prices offered are cheap, the facilities provided are complete, employee service is good, and the location is strategic. Batoe 54 Swimming Pool has shortcomings such as moss in the pool, lack of promotion, and some facilities are still not suitable for use. Strategies to overcome these shortcomings are improving product quality, adjusting prices more competitively, more effective promotions, paying attention to customer service aspects, and the physical environment so that the visitor experience becomes better.

The robotic manta has attracted significant interest for its exceptional maneuverability, swimming efficiency, and stealthiness. However, achieving efficient autonomous swimming in complex underwater environments presents a significant challenge. To address this issue, this study integrates Deep Deterministic Policy Gradient (DDPG) with Central Pattern Generators (CPGs) and proposes a CPG-based DDPG control strategy. First, we designed a CPG control strategy that can more precisely mimic the swimming behavior of the manta. Then, we implemented the DDPG algorithm as a high-level controller that adaptively modifies the CPG’s control parameters based on the real-time state information of the robotic manta. This adjustment allows for the regulation of swimming modes to fulfill specific tasks. The proposed strategy underwent initial training and testing in a simulated environment before deployment on a robotic manta prototype for field trials. Both further simulation and experimental results validate the effectiveness and practicality of the proposed control strategy.

Abstract High abundance of Northeast Atlantic mackerel (Scomber scombrus L.), combined with limited food resources, may now force mackerel to enter new and productive regions in the northern Norwegian Sea. However, it is not known how mackerel exploit the spatially varying feeding resources, and their vertical distribution and swimming behaviour are also largely unknown. During an ecosystem survey in the Norwegian Sea during the summer feeding season, swimming direction, and speed of mackerel schools were recorded with high-frequency omnidirectional sonar in four different regions relative to currents, ambient temperature, and zooplankton. A total of 251 schools were tracked, and fish and zooplankton were sampled with pelagic trawl and WP-2 plankton net. Except for the southwest region, swimming direction of the tracked schools coincided with the prevailing northerly Atlantic current direction in the Norwegian Sea. Swimming with the current saves energy, and the current also provides a directional cue towards the most productive areas in the northern Norwegian Sea. Average mean swimming speed in all regions combined was ∼3.8 body lengths s−1. However, fish did not swim in a straight course, but often changed direction, suggesting active feeding in the near field. Fish were largest and swimming speed lowest in the northwest region which had the highest plankton concentrations and lowest temperature. Mackerel swam close to the surface at a depth of 8–39 m, with all schools staying above the thermocline in waters of at least 6°C. In surface waters, mackerel encounter improved foraging rate and swimming performance. Going with the flow until temperature is too low, based on an expectation of increasing foraging rate towards the north while utilizing available prey under way, could be a simple and robust feeding strategy for mackerel in the Norwegian Sea.

Learning outcomes This paper aims to enable students craft a winning corporate strategy applicable for organizations in various contexts. The practical approach consists of conducting scenario planning based on internal and external environment analysis, identifying the winning factor, proposing an implementation strategy of entry and exit strategies, and future customers, and evaluating matching of business ethics and legality. Case overview/synopsis Wesley Chen, the executive director and group chief executive officer, has the ultimate challenge of leading his management team to operate from a sole proprietorship management style to a listed large company in the Malaysian Stock Exchange. He identified the gap in the need to craft a winning corporate strategy for business sustainability. The corporate strategy should address expansion of their service offerings and needs to be carefully crafted to suit TopSteel’s risk appetite and overall business strategy. The strategy must also consider the internal and external factors that TopSteel faced with, identify the core competency of TopSteel, build in strategic agility in the implementation plans to address the dynamic business landscape, and most importantly ensure the corporate strategy must be in compliance to ethical and legal standards. The case study documents the one year of transition of TopSteel’s operations with a strong focus on the strategic management process direction for a winning OEM+ model through the use of SWIM concept.

Bluegill sunfish use intermittent propulsion during volitional swimming. The function of this propulsive mode during routine swimming has not been well quantified. At low speeds, propulsive cycle frequencies and amplitudes were constant, and average speed and power output were controlled by modulating coasting duration. This fixed-gear gait may accommodate muscle level constraints on power production. At higher speeds bluegills switched to a mixed power-modulation strategy, increasing speed and power through increased propulsive cycle frequency and reduced coasting time.

Swimming performance and behaviour in fish has been shown to vary depending on the investigation method. In this study, an endurance swimming curve was generated for young-of-the-year shortnose sturgeon (Acipenser brevirostrum LeSueur, 1818) (~7 cm total length, ~2 g) and compared with values determined in a separate incremental swimming (critical swimming, Ucrit) test. Using video, tail-beat frequency (TBF) was quantified and compared for fish swimming under both swimming tests. From the endurance-curve analysis, it was found that sturgeon did not display a statistically significant burst swimming phase. Maximum sustainable swimming speed (calculated to be 18.00 cm·s–1) from the endurance curve occurred at ~80% of Ucrit (22.30 cm·s–1). TBF was similar at all speeds for both swimming tests, except at speeds approaching Ucrit, where fish displayed TBFs of 4.29 Hz for the endurance protocol and 2.26 Hz for the Ucrit protocol. TBF was more variable between individuals swimming at the same speed within the Ucrit compared with the endurance protocol. Finally, a significant negative correlation was found between TBF and Ucrit in individual fish, suggesting that station-holding may be an important energy saving strategy during swimming in this size class of sturgeon.

It has been hypothesized that large differences in maximal performance can arise between various geopolitical regions solely on the basis of differing numbers of participants in the target activity. While there is evidence in support of this hypothesis for a measure of intellectual performance, the same relationship has not been examined for a measure of physical performance.Purpose:To determine whether the number of participants is a predictor of the best athletic performance in a region.Methods:The 2005–2010 USA Swimming Age Group Detail reports were used to determine the number of competitive swimmers participating in each age group for the 59 local swimming communities in the United States. The USA Swimming performance database provided 50-yd-freestyle times in each community for boys and girls for each age (6–19 y). Simple linear regression was used to examine the relationship between the outcome variable (fastest time) and the predictor variable (log of the number of swimmers) for each combination of age, sex, and calendar year.Results:The log of the number of swimmers in a region was a significant predictor of the best performance in that region for all 168 combinations of age, sex, and calendar year (P < .05) and explained, on average, 41%, and as much as 62%, of the variance in the fastest time.Conclusions:These findings have important implications for the development of regional sport strategic policy. Increasing the number of participants in the target activity appears a viable strategy for improving regional performance.

Calanoid copepods represent a major component of the plankton community. These small animals reside in constantly flowing environments. Given the fundamental role of behaviour in their ecology, it is especially relevant to know how copepods perform in turbulent flows. By means of three-dimensional particle tracking velocimetry, we reconstructed the trajectories of hundreds of adult Eurytemora affinis swimming freely under realistic intensities of homogeneous turbulence. We demonstrate that swimming contributes substantially to the dynamics of copepods even when turbulence is significant. We show that the contribution of behaviour to the overall dynamics gradually reduces with turbulence intensity but regains significance at moderate intensity, allowing copepods to maintain a certain velocity relative to the flow. These results suggest that E. affinis has evolved an adaptive behavioural mechanism to retain swimming efficiency in turbulent flows. They suggest the ability of some copepods to respond to the hydrodynamic features of the surrounding flow. Such ability may improve survival and mating performance in complex and dynamic environments. However, moderate levels of turbulence cancelled gender-specific differences in the degree of space occupation and innate movement strategies. Our results suggest that the broadly accepted mate-searching strategies based on trajectory complexity and movement patterns are inefficient in energetic environments.

Nongovernmental organisations (NGOs) have come to play a major role in contemporary governance systems, and particularly in the fields of water and the environment. Adopting a new institutional theoretical perspective, this thesis examines how rules and norms affect the advocacy strategies of coalitions of NGOs in Vietnam and Cambodia, utilising a comparative case study analysis of the Xayaburi hydropower dam planned on the Mekong River in Laos. The comparison was conducted between the Rivers Coalition in Cambodia and the Vietnam Rivers Network during the planning period for the dams in 2011-2013.The main findings of the study is that rules, norms, actors, biophysical and material conditions interact with each other in creating influence over advocacy strategies. Different patterns of interactions were identified; these are 1) complementary interactions between formal rules, informal rules and norms 2) competing interactions between formal rules, informal rules and norms. Actors play important roles in both of these forms of interactions. Through identification of the barriers and opportunities NGO actors face within the Mekong region, the thesis concludes with two recommendations: 1) modifications to the formal rules which could facilitate further integration of NGOs and civil society actors into decision-making processes of transboundary water governance and 2) use of analytical framework by NGO and civil society actors in identifying windows of opportunities for advocacy strategies.

Les bactéries présentent une diversité de comportements de motilité, essentielle à leur survie dans des environnements complexes. Comprendre ces mécanismes de motilité, en particulier dans des espaces confinés, est crucial pour l'écologie microbienne et le développement de technologies bio-inspirées. Cette thèse explore le transport bactérien dans des espace confinés en utilisant des modèles théoriques, numériques et expérimentaux pour prédire le mouvement bactérien dans des canaux en forme de fente et des milieux poreux, et pour identifier des stratégies optimales de dispersion. La thèse est organisée en quatre chapitres. Le premier chapitre passe en revue l’état de l’art sur la recherche en motilité bactérienne. Le deuxième chapitre développe un nouveau cadre permettant de prédire la dispersion des particules de type "Run-and-Tumble" dans des canaux à parois parallèles, apportant des informations clés sur les mouvements optimaux. Le troisième chapitre se concentre sur les milieux poreux et présente un nouveau modèle capable de prédire la diffusivité bactérienne à travers une large variété de modalité de déplacement et de conditions environnementales. Le quatrième chapitre présente des études expérimentales sur une nouvelle souche de bactéries magnétotactiques, en examinant leur réponse magnétique et leurs interactions avec des interfaces solides. Cette thèse présente des résultats prometteurs qui contribuent aux domaines de la motilité bactérienne et de la matière active. Elle comble notamment un manque de compréhension concernant la dispersion dans des environnements confinés. De manière plus large, les résultats trouvent des applications potentielles dans des domaines allant du génie biologique à la recherche microbienneBacteria exhibit diverse motility behaviors, which are key to their survival in complex environments. Understanding these motility mechanisms, particularly in confined spaces, is crucial for microbial ecology and the development of bio-inspired technologies. This thesis investigates bacterial transport in confined environments, using theoretical, numerical, and experimental models to predict bacterial motion in slit-like channels and porous media, and to identify optimal strategies for dispersion. The thesis is organized into four chapters. The first chapter reviews the state of the art in bacterial motility research. The second chapter develops a new framework to predict the dispersal of Run-and-Tumble particles in slit-like channels, providing key insights into optimal motion. The third chapter shifts to porous media, presenting a new model capable of predicting bacterial diffusivity across a wide variety of swimmer models and environmental conditions. The fourth chapter focuses on experimental studies with a novel strain of Magnetotactic Bacteria, examining their magnetic response and interactions with solid interfaces. This thesis presents promising results that contribute to the fields of bacterial motility and active matter. Specifically, it addresses the previous lack of understanding of bacterial dispersal in confined environments. More broadly, the findings offer potential applications in fields ranging from bioengineering to microbial research

L’océan austral est un écosystème fragile dont la dynamique est influencée par des variations climatiques qui vont structurer la distribution spatio-temporelle des ressources. L’objectif de cette thèse était d’étudier les stratégies d’acquisition des ressources en proies mises en place par l’éléphant de mer austral face aux contraintes énergétiques (coûts du transport et coûts d’accès à la ressource) et temporelles (temps passé au fond d’une plongée et limite de plongée aérobie) auxquelles il est soumis. L’utilisation d’un ensemble d’enregistreurs de données déployés sur ces animaux a permis de reconstruire en trois dimensions leur plongée, mais également de calculer leur effort de nage, le nombre de proies rencontrées ainsi que leur dépense énergétique. Notre étude montre qu’à l’échelle d’une plongée, les éléphants de mer adaptent leur trajectoire, mais également le temps qu’ils passent au fond, en fonction du nombre de proies rencontrées. Pour des densités locales de proie importantes, ils passent plus de temps au fond, et concentrent leur recherche en zone restreinte, caractérisée par une diminution de la vitesse et une augmentation de la sinuosité horizontale. Au-delà de 550 m, le coût d’accès aux ressources devient supérieur aux coûts d’acquisition ; ils doivent alors faire face à un compromis entre l’accessibilité et la disponibilité en proies. À mesure qu’ils s’alimentent, ces phoques augmentent leur flottabilité, diminuant de surcroît leur dépense énergétique. Cette étude démontre également une structuration spatio-temporelle de cette dépense énergétique qui semble être liée au succès d’alimentation et donc à la distribution des ressources en proiesThe Southern Ocean is a fragile ecosystem whose dynamics are influenced by climate change that will structure the spatio-temporal distribution of resources. The objective of this PhD was to investigate the foraging strategies used by the southern elephant seal, under energetic (cost of transport and costs of access to the resource) and temporal (time at the bottom of a dive and aerobic dive limit) constraints. Using a set of animal-borne data loggers allowed us to reconstruct their three-dimensional path underwater, but also to calculate their swimming effort, the number of prey encountered and their energy expenditure. At the dive level, our study shows that elephant seals adapt their path, but also the time spent at the bottom, depending on the number of prey encountered. For high local prey density, they spent more time at the bottom, and concentrated their foraging effort in areas restricted search, characterized by a decrease in speed and an increase in horizontal sinuosity. Beyond 550 m, the cost of access to resources becomes greater than the cost of acquisition ; they must therefore deal with a trade-off between prey accessibility and availability. While feeding, these seals increase their buoyancy, reducing furthermore their energy expenditure. This study also shows a spatio-temporal structure of the energy expenditure that appears to be related to feeding success and therefore to prey resources distribution

The study was preceded with a method of active research. Main aim of this study was to investigate the implementation of swimming teaching strategy, which included the effectiveness of improving the level of the primary school swimmers, teachers’ role in the implementation of swimming teaching strategy, students’ attitude toward the process of implementing the swimming teaching strategy. Furthermore, it will discuss the limitations and their responses of the implementation of swimming teaching strategy in practise. In order to achieve the aim of this study, the author had designed teaching structural framework and teaching activity according to the result the secondary research data evaluation. Prior to the teaching, an investigation was conducted targeting the second grade of the school via the ‘beginner swimmers’ test’ to establish a starting point. Various tests include ‘water adaptability test’, ‘swimming ability test’, ‘crawl-stroke ability test’ and ‘breast-stroke’ were conducted after the practical classes in order to compare and analyse their effectiveness. At the same time the, continuous analysis, cross examination and comparisons of various transformations amongst students before and after the implementation of the swimming teaching strategy were conducted. These were done with the combination of teaching journal, student books, observation reports, interview records, evaluation records, discussions and conversations of the assisting experts and various data. The study results are concluded as the following: 1 Effectiveness of the Swimming Teaching Strategy in the improvement of primary school pupils’ swimming ability: 1.1 Vast improvement in pupils’ water adaptability; 1.2 Improvement in pupils’ swimming ability; 1.3 Better understanding of the crawl stroke and breast stroke amongst the pupils; 1.4 Improvement of pupils’ physical strength; 1.5 Improved learning via ‘oral teaching’; and 1.6 Improve pupils’ confidence, motivate their learning interest and improve learning effectiveness via the teaching of applied strategy. 2 During the implementation of the swimming teaching strategy, on the aspect of development, teachers assume the role of researcher, motivator and observer. On the aspect of correction, teachers assume the role of designer, demonstrator and trainer. On the remediation aspect, teachers assume the role of referee and the evaluator of one’s action. 3 Pupils have positive attitude toward the teachers and the content of teaching during the process of swimming teaching strategy implementation, as well as a strict self demand. An increasing familiarity with swimming accompanying by a gradual establishment of leisure habit. 4 Limitations and responses of the implementation of swimming teaching strategy in the actual teaching scenario: 4.1 Insufficient lesson time. Solved by extracurricular lessons and develop pupils’ ability in independent learning; 4.2 Insufficient professional expertise amongst the teaching staff. Solved by further learning and the establishment of co-teaching method; 4.3 The traditional evaluation method is unable to motivate the students. Solved by the use of selective evaluation, self evaluation and assessment sheet, to allow the students to self monitor revise. 4.4 Insufficient swimming facilities. This was solved by the development of multimedia teaching, accreditation and award measures. Finally, according to the conclusions mentioned above, recommendations made in the aspects of lesson design, teaching time arrangement, application of teaching methods and the application of financial recourses are provided as the references for those interested.’

The purpose of this study was to investigate the marketing strategies and risk management practices of pre-school swimming courses. The researcher conducted semi-structured in-depth interviews with 3 purposively sampled pre-school swimming instructors employed at private swimming schools. He also transcribed the contents of the interviews for coding and analyzing. The results were as follows: (a) in running the programs, some pre-school swimming courses aimed to promote parent-child relation through swimming, whereas others were more business oriented; Japanese instruction emphasized more on the parent-child interaction, English style cared more on children’s sensory development, and YMCAs with Japanese philosophy further incorporated aerobic activities in the swimming courses; the program operators usually promoted their courses through or by social media such as FB and its official web site, distributing advertisement flyers, briefing during swimming classes, parents’ worth of mouth, and providing free trial lessons; fees for the courses were set differently based on equipment and facility quality to attract parents from the upper class and the average family, respectively; parents who had a stronger sense of child protection and were critical on privacy and environment hygiene factors tended to select higher priced programs; and (b) negligence of parents or instructors during the instruction was a more often seen risk for pre-school swimming courses; parents’ handling skills and comforting voices provided a sense of safety for the children and ensured a more smooth learning process; insurance policy was mainly planned for facility and site aspects, given the probability of severe injuries of the children were very unlikely; setting emergency treatment procedures in advance was the standard approach applied to minimize damage as risk control measures failed.

After the relationship has been eased between Taiwan and China, KinMeng has become a model county that promotes the interrelation of the two countries, and this series of opening up borders has, not only meaning a lot for Taiwan and China but also changing the KinMeng’s society and economy, shifted people there in the way of their awareness and thinking. This research takes long distance swimming activity as an example, analyzing the effectiveness of using athletic activities to promote the city, discussing service marketing design of athletic activities by adopting case study, and inducting the successful factors of an athletic activity that trigger the tourism of the city. This research has, in the duration of the actual development stage, adopted professional interview to proceed with the targeted case study as well as data collection, analysis and comparison. The result shows that different “service provider”, “service procedure”, and “service location” can enhance the shaping, liable, responding, ensuring and the sympathetic characteristics of the service, while different service takers can enhance the shaping, ensuring and sympathetic characteristics of the service quality. The long distance swimming activity can change the acknowledgement of and the willingness to travel to KinMeng, but the attitude towards KinMeng has long been influenced by tits stereotype image and hence has very little change. At the end this research lists some concluding suggestions for the government, tourism and related industries, as well as some reference for future study.

The energetic costs of terrestrial locomotion are placed in the context of the fuel sources that animals use for generating adenosine triphosphate (ATP) and how these fuel sources affect an animal’s capacity for sustainable aerobic metabolism. Aerobic capacity and energy use are closely linked to an animal’s thermoregulatory strategy. Patterns of energy use across terrestrial gaits, sloped substrates and level ground are examined alongside explanatory models. The energetics of terrestrial locomotion is compared with the energetics of swimming and flight. Whereas the support of an animal’s weight against gravity dominates the cost of moving on land and through air, overcoming resistive forces of drag strongly affects the energy cost of movement through water and air. The physical properties of land, water and air influence how energy use changes with the speed of movement. Given these energetic considerations, animals use different locomotor strategies and mechanisms to avoid fatigue and increase endurance capacity.

Some people have a drink when they get home from work—a martini, a beer. Maybe two or three. Life is especially stressful in the twenty-first century. The same indecent forces that are destroying nature are disrupting our working lives as well. Who will own the company tomorrow? Will there be a “reduction in force” or some other euphemism for the ax? When is the next reorganization coming? Is my ten or twenty years of faithful service an asset or, more likely, a sign of obsolescence and suspicious loyalty to bosses and co-workers now out of favor or working for other companies? How am I to answer the fax that arrived at 4:00 p.m., the one that seemed to contradict the fax that arrived at 11:00? When will I find time to fill out the questionnaire from the Resource Management Office, and does it take precedence over the Goals Enhancement Strategy questionnaire that came from the Administrative Services Division? Are my computer files compatible with the new software system, and, if so, why did the box on the screen say, “This paragraph is un-readable. Do you wish to substitute a standard paragraph?” Just what is our real work, anyway? Alcohol can take the edge off stress, but it is not everyone’s consolation. Some choose television or the Internet; mine is to pick up one of the scores of detective novels that I keep close to hand and plunge in. Then I can forget for a little while the vice presidents, deans, and other academic, corporate-style bosses who do their best to make life in the modern university an unproductive misery. In this way I can put out of mind, temporarily, the pleas of students who don’t understand why there are no courses to take and the ravings of colleagues who can’t figure out how to cope with the contradictory, impossible demands placed on them. Why should detective stories be, for so many, such a good and entertaining way of escaping from reality? That they are is clear; billions of copies have been sold.

As described in the previous chapter, children’s thinking is highly variable. The present chapter focuses on implications of this variability for understanding development. Thinking about a pair of visual metaphors may help facilitate recognition of these implications. The first, which I believe underlies most depictions of development, is the staircase metaphor. The second, which I believe offers a superior alternative, is the overlapping waves metaphor. Cognitive developmentalists have often phrased their models in terms that suggest that children of a given age think about a given task in a single way. W-year-olds are said to have a particular mental structure, a particular processing limit, a particular theory, strategy, or rule that gives rise to a single type of behavior. Change involves a substitution of one mental entity (and accompanying behavior) for another. The basic conceptualization that seems to underlie these models is aptly captured in the title of Robbie Case’s (1992) recent book The Mind’s Staircase. The visual metaphor that this title evokes is, I believe, central to most cognitive-developmental treatments of change: Children are depicted as thinking in a given way for an extended period of time (a tread on the staircase); then their thinking undergoes a sudden, vertical shift (a riser on the staircase); then they think in a different, higher way for another extended period of time (the next tread); and so on. This view of development is most closely identified with Piagetian and neo-Piagetian approaches, such as those of Piaget and Case. Thus, as shown in Figure 4.1, we see development depicted within Piaget’s theory as involving sensorimotor activities from birth to about 2 years; preoperational thinking from 2 to 7 years; concrete operational thinking from 7 to 12 years; and formal operational thinking from 12 years onward. Within Case’s theory, we see thinking depicted as advancing from the sensorimotor level between birth and 18 months, to the relational level from 18 months to 5 years, to the dimensional level between 5 and 11 years, and to the formal level at age 11 and beyond. Although this view of development is associated with the Piagetian and neo-Piagetian traditions, it is far from unique to them.

All along, human exploration of the ocean has never stopped, and bionic fish robots have been produced. Currently, bionic fish have been used in a range of fields, including underwater archaeology, water quality monitoring, and other fields, because of their camouflage and flexibility. The bionic fish also can perform observation, reconnaissance, and other jobs, reduce battle risks, and play a crucial role in contemporary military tasks. It is increasingly being implemented in the military sphere. The efficacy of the bionic fish’s tail mechanism in terms of swimming and reconnaissance is crucial to the design of the fish. However, multiple servo joints are frequently used in the current bionic fishtail system, which increases the likelihood of failure. This research suggests a fishtail design strategy based on the transmission mechanism to operate more steadily. After analyzing the existing bionic fish mechanical structures, research proposes the schemes of living in three mechanical structures. By combining the actual fish body size, the comprehensive modeling design was carried out using Solid Work software, and the motion performance analysis of the mechanism was analyzed by Adams software. The experimental results provide a theoretical and reference for the actual design of bionic robotic fish.

<em>Abstract.</em>—This paper examines how allometric analysis can be used as a tool to explain morphological changes that take place during fish larval development. First, constraints to survival, growth, and continued differentiation are identified. Then, processes of growth are predicted to meet and overcome these constraints, which are mutually interrelated. The final step is to test the predictions by looking at growth of the entire animal and at separate elements belonging to particular functional systems. The reproductive strategy of producing numerous, but very small eggs, adopted by many teleosts, has major implications. In particular, the lack of reserves, the need to utilize external food early in life, and the extreme susceptibility of newly hatched larvae to predation put them under strong selective pressure to grow rapidly. Small size also means that viscous forces are much more important than they are at bigger size later in life. When energy is limited, larvae should direct available resources towards primary needs yielding the greatest return in terms of enhancing the larva’s ability to find, capture, and assimilate additional food and to avoid being eaten. We speculate that constructions for feeding, swimming, and ventilation are particularly important and should therefore grow early and at a higher rate than the body as a whole. Allometric data of a wide variety of species and taken from several functional complexes are presented to support this contention. Length dependent changing growth coefficients of head, trunk, and tail indeed show the predicted priorities in different major groups of fish. High positive allometric growth of structures involved in feeding make early larvae specialized zooplanktivorous predators.

Abstract Reproduction is a strictly solitary activity in most animal species. Females (or hermaphrodites) typically pair briefly with males (or other hermaphrodites) to acquire unrelated haploid genomes, and in some species males package their sperm with nutritional resources that females incorporate into eggs. But in the vast majority of species, all subsequent parental investment is the work of one individual: mother. Many invertebrates even forgo mating in the usual sense, as in sessile species where free-swimming sperm find either the females or their free-floating haploid eggs, and species in which mobile females collect spermatophores that were previously deposited at strategic locations by anonymous donors.

On December 24, 1989, a man named Charles Taylor marshaled a band of armed rebels in the northern part of Liberia, a small country on the coast of West Africa. Carpeted in green jungle crossed by the occasional red dirt road connecting remote ramshackle towns, Liberia had never managed to attract much attention from the outside world. It carried none of the economic clout or strategic importance of continental powers like Kenya and South Africa. To outsiders, Liberia figured as little more than a historical curiosity, the place where freed American slaves settled and founded Africa’s first independent republic in 1847. Nor did Charles Taylor’s activities attract much notice. Military coups are a common occurrence throughout Africa, as much a part of reality as the tropical downpours that bring life to a temporary standstill in thousands of villages across the landscape before people tentatively poke out their heads and resume their daily activities. But this time something was different. Instead of racing to the capital and storming the presidential palace—as the incumbent dictator, Samuel Doe, had done a decade earlier—Taylor and his men were slow and deliberate in their progress, taking control of one town after the next. Rumors spread that the rebels were supported by Libya, a country that exercises much greater influence throughout the African continent than most people realize. Ultimately Charles Taylor would orchestrate a catastrophic civil war in Liberia, a conflict that would engulf neighboring Sierra Leone and lead to one of the worst humanitarian crises of the past century. At the time I was serving as a Peace Corps volunteer in Liberia, where my wife and I were assigned to work in President Doe’s hometown of Zwedru, a remote place that could only be reached through days of travel along roads with mud pits the size of swimming pools or, alternatively, in a single-propeller plane that the tropical air currents would toss about like a toy in a bathtub. It was in Liberia that I first came to appreciate how national governance impacts the lives of billions of people every day.

According to the shortages of previous generation of frog inspired robot, antagonistic joint based frog inspired leg was designed. With the multi-DOFs of hip, knee and ankle, the designed leg was able to perform various frog swimming modes. The dynamic model of antagonistic joint based on advanced pneumatic muscle model was established in MATLAB/Simulink environment. Besides, the servo control strategy of joint angle was studied based on the dynamic model of antagonistic joint. The PID and self-tuning fuzzy control were utilized to control the antagonistic joint. According to different swimming modes, joint trajectories of hip, knee and ankle were created by inverse kinematics based on the frog swimming mechanism. Therefore, the leg was controlled by the separated controls of hip, knee and ankle joints. Feasibility of pneumatic antagonistic joint control was validated via step response experiments with different loads. Finally, the experiment platform was established to carry swimming experiments with the developed frog-inspired swimming leg. The feasibility of antagonistic frog inspired swimming leg driven by pneumatic muscles was validated.

Abstract The study of fish swimming is of great interest for engineers and researchers because the investigation of novel propulsion mechanisms is functional to the development of autonomous underwater vehicles. Among the different locomotion strategies adopted by fish species, the one characterizing the cownose ray is known to be very efficient. These fishes move their large pectoral fins and create a wave travelling in a direction opposite to the swimming direction. Thus, thanks to momentum conservation, the fish receives a propulsive thrust. This mechanism has been reproduced in a bioinspired robot mimicking a cownose ray, which has been designed and built. Before testing the robot underwater, some preliminary experiments in a small wind tunnel have been performed on a single fin. These tests are aimed at assessing the fluid dynamics of the fin shape and at verifying the effectiveness of this propulsive strategy. The fluid dynamic forces acting on the profile are measured with the fin still; the velocity of the incoming air is such that the Reynolds number is the same as for the fish swimming in water. Then, the propulsive strategy is tested with the fin in motion; the velocity of the incoming air is the same as the relative velocity of water for the fish during forward swimming, and several experiments were carried out with different frequencies and wavelengths of fin motion. Finally, having the fluids different densities, the measured forces and moments are scaled. These tests have confirmed that the cownose ray swimming strategy is effective and a relation between the measured forces with frequency and wavelength of fin motion has been found.

This paper aims to study and to evaluate two distinct approaches for detecting water tanks and swimming pools in satellite images, which can be useful to monitor waterrelated diseases. The first approach, shallow, consists of using a Support Vector Machine in order to classify into positive and negative a discretized color histogram of a given segment of the original image. The second method employs the Faster R-CNN framework for detecting those objects. We built up swimming pools and water tanks datasets over the city of Belo Horizonte to support our experimental analysis. Our results show that the deep learning method greatly outperforms the shallow strategy, achieving an average precision at 0.5 IoU of over 93% on the swimming pool detection task, and over 73% on the water tank one. All the code and datasets are publicly available.

Abstract Metachronal motion is a unique swimming strategy widely adopted by many small animals on the scale of microns up to several centimeters (e.g., ctenophores, copepods, krill, and shrimp). During propulsion, each evenly spaced appendage performs a propulsive stroke sequentially with a constant phaselag from its neighbor, forming a metachronal wave. To produce net thrust in the low-to-intermediate Reynolds number regime, where viscous forces are dominant, the beat cycle of a metachronal appendage must present significant spatial asymmetry between the power and recovery stroke. As the Reynolds number increases, the beat cycle is observed to change from high spatial asymmetry to lower spatial asymmetry. However, it is still unclear how the magnitude of spatial asymmetry can modify the shear layers near the tip of appendages and thus affect its associated hydrodynamic performance. In this study, ctenophores are used to investigate the hydrodynamics of multiple appendages performing a metachronal wave. Ctenophores swim using paddle-like ciliary structures (i.e., ctenes), which beat metachronally in rows circumscribing an ovoid body. Based on high-speed video recordings, we reconstruct the metachronal wave of ctenes for both a lower spatial asymmetry case and a higher spatial asymmetry case. An in-house immersed-boundary-method-based computational fluid dynamics solver is used to simulate the flow field and associated hydrodynamic performance. Our simulation results aim to provide fundamental fluid dynamic principles for guiding the design of bio-inspired miniaturized flexible robots swimming in the low-to-intermediate Reynolds number regime.

Abstract As part of the Monaco offshore urban extension project, Bouygues TP is in charge of design & build a maritime infrastructure as the first step of the six-hectare expansion of the city into the sea. This maritime infrastructure consists of a fill enclosed by a band of trapezoid concrete caissons and will serve as base for construction of the new residential area. The paper focuses on some of the problems which had to be solved: optimization of promenade level and wave absorbing chambers in conjunction with minimal reflection and safety related to overtopping, accounting for sea level rise and correlation between extreme waves and water levels. caissons and rubble mound foundation stability related to waves and seism, including extra seismic forces due to buildings considering the high reclamation height and the immediate proximity of building foundations. the way in which caissons representing nearly 80,000 m3 of concrete can be built in a floating and continuous manner via a caisson box (or "caissonnier" in French), within a particularly short time frame presence of a small craft harbor with shops along the quays, whose location was fixed for urbanistic reasons, which requested optimizations in detail of anti-overtopping devices as much as possible integrated in the urban context, need to convert a breakwater caisson into a low crested swimming pool caisson, with plexiglas windows exposed to wave slamming from outside, but also from inside due to overtopping impacts over the swimming pool basin. Ecodesign has been closely associated with hydrodynamic and coastal engineering, based on estimation of wave pressures and induced velocities in the different possible locations (chambers, walls, structures toes …). The eco-friendly development strategy is based on the wide-scale deployment of a range of 11 solutions which will be described (potential for caissons to be colonized, nursery function development, etc…). Moreover, posidonia transplantation has been done via concrete open boxes, whose stability under storm waves has requested CFD calculations to model local velocities and optimize their shape.

Harmful Algal Research & Response: A National Environmental Science Strategy (HARRNESS), 2024-2034. Woods Hole Oceanographic Institution, Juli 2024. http://dx.doi.org/10.1575/1912/69773.

Harmful and toxic algal blooms (HABs) are a well-established and severe threat to human health, economies, and marine and freshwater ecosystems on all coasts of the United States and its inland waters. HABs can comprise microalgae, cyanobacteria, and macroalgae (seaweeds). Their impacts, intensity, and geographic range have increased over past decades due to both human-induced and natural changes. In this report, HABs refers to both marine algal and freshwater cyanobacterial events. This Harmful Algal Research and Response: A National Environmental Science Strategy (HARRNESS) 2024-2034 plan builds on major accomplishments from past efforts, provides a state of the science update since the previous decadal HARRNESS plan (2005-2015), identifies key information gaps, and presents forward-thinking solutions. Major achievements on many fronts since the last HARRNESS are detailed in this report. They include improved understanding of bloom dynamics of large-scale regional HABs such as those of Pseudo-nitzschia on the west coast, Alexandrium on the east coast, Karenia brevis on the west Florida shelf, and Microcystis in Lake Erie, and advances in HAB sensor technology, allowing deployment on fixed and mobile platforms for long-term, continuous, remote HAB cell and toxin observations. New HABs and impacts have emerged. Freshwater HABs now occur in many inland waterways and their public health impacts through drinking and recreational water contamination have been characterized and new monitoring efforts have been initiated. Freshwater HAB toxins are finding their way into marine environments and contaminating seafood with unknown consequences. Blooms of Dinophysis spp., which can cause diarrhetic shellfish poisoning, have appeared around the US coast, but the causes are not understood. Similarly, blooms of fish- and shellfish-killing HABs are occurring in many regions and are especially threatening to aquaculture. The science, management, and decision-making necessary to manage the threat of HABs continue to involve a multidisciplinary group of scientists, managers, and agencies at various levels. The initial HARRNESS framework and the resulting National HAB Committee (NHC) have proven effective means to coordinate the academic, management, and stakeholder communities interested in national HAB issues and provide these entities with a collective voice, in part through this updated HARRNESS report. Congress and the Executive Branch have supported most of the advances achieved under HARRNESS (2005-2015) and continue to make HABs a priority. Congress has reauthorized the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA) multiple times and continues to authorize the National Oceanic and Atmospheric Administration (NOAA) to fund and conduct HAB research and response, has given new roles to the US Environmental Protection Agency (EPA), and required an Interagency Working Group on HABHRCA (IWG HABHRCA). These efforts have been instrumental in coordinating HAB responses by federal and state agencies. Initial appropriations for NOAA HAB research and response decreased after 2005, but have increased substantially in the last few years, leading to many advances in HAB management in marine coastal and Great Lakes regions. With no specific funding for HABs, the US EPA has provided funding to states through existing laws, such as the Clean Water Act, Safe Drinking Water Act, and to members of the Great Lakes Interagency Task Force through the Great Lakes Restoration Initiative, to assist states and tribes in addressing issues related to HAB toxins and hypoxia. The US EPA has also worked towards fulfilling its mandate by providing tools and resources to states, territories, and local governments to help manage HABs and cyanotoxins, to effectively communicate the risks of cyanotoxins and to assist public water systems and water managers to manage HABs. These tools and resources include documents to assist with adopting recommended recreational criteria and/or swimming advisories, recommendations for public water systems to choose to apply health advisories for cyanotoxins, risk communication templates, videos and toolkits, monitoring guidance, and drinking water treatment optimization documents. Beginning in 2018, Congress has directed the U.S. Army Corps of Engineers (USACE) to develop a HAB research initiative to deliver scalable HAB prevention, detection, and management technologies intended to reduce the frequency and severity of HAB impacts to our Nation’s freshwater resources. Since the initial HARRNESS report, other federal agencies have become increasingly engaged in addressing HABs, a trend likely to continue given the evolution of regulations(e.g., US EPA drinking water health advisories and recreational water quality criteria for two cyanotoxins), and new understanding of risks associated with freshwater HABs. The NSF/NIEHS Oceans and Human Health Program has contributed substantially to our understanding of HABs. The US Geological Survey, Centers for Disease Control and Prevention, and the National Aeronautics Space Administration also contribute to HAB-related activities. In the preparation of this report, input was sought early on from a wide range of stakeholders, including participants from academia, industry, and government. The aim of this interdisciplinary effort is to provide summary information that will guide future research and management of HABs and inform policy development at the agency and congressional levels. As a result of this information gathering effort, four major HAB focus/programmatic areas were identified: 1) Observing systems, modeling, and forecasting; 2) Detection and ecological impacts, including genetics and bloom ecology; 3) HAB management including prevention, control, and mitigation, and 4) Human dimensions, including public health, socio-economics, outreach, and education. Focus groups were tasked with addressing a) our current understanding based on advances since HARRNESS 2005-2015, b) identification of critical information gaps and opportunities, and c) proposed recommendations for the future. The vision statement for HARRNESS 2024-2034 has been updated, as follows: “Over the next decade, in the context of global climate change projections, HARRNESS will define the magnitude, scope, and diversity of the HAB problem in US marine, brackish and freshwaters; strengthen coordination among agencies, stakeholders, and partners; advance the development of effective research and management solutions; and build resilience to address the broad range of US HAB problems impacting vulnerable communities and ecosystems.” This will guide federal, state, local and tribal agencies and nations, researchers, industry, and other organizations over the next decade to collectively work to address HAB problems in the United States.
