Abstract:
Van Gelder's specification of the dynamical hypothesis does not improve on previous notions. All three key attributes of dynamical systems apply to Turing machines and are hence too general. However, when a more restricted definition of a dynamical system is adopted, it becomes clear that the dynamical hypothesis is too underspecified to constitute an interesting cognitive claim.

Abstract:
According to the dominant computational approach in cognitive science, cognitive agents are digital computers; according to the alternative approach, they are dynamical systems. This target article attempts to articulate and support the dynamical hypothesis. The dynamical hypothesis has two major components: the nature hypothesis (cognitive agents are dynamical systems) and the knowledge hypothesis (cognitive agents can be understood dynamically). A wide range of objections to this hypothesis can be rebutted. The conclusion is that cognitive systems may well be dynamical systems, and only sustained empirical research in cognitive science will determine the extent to which that is true.

Abstract:
Research in attitudes and social cognition exemplifies van Gelder's distinction between the computational and dynamical approaches. The former emphasizes linear measurement and rational decision-making. The latter considers processes of associative memory and self-organization in attitude formation and social influence. The study of dynamical processes in social cognition has been facilitated by connectionist approaches to computation.

Abstract:
What new implications does the dynamical hypothesis have for cognitive science? The short answer is: none. The target article is basically an attack on traditional symbolic artificial intelligence (AI) and differs very little from prior connectionist criticisms of it. For the past 10 years, the connectionist community has been well aware of the necessity of using (and understanding) dynamically evolving, recurrent network models of cognition.

Abstract:
Van Gelder presents the dynamical hypothesis as a novel law of qualitative structure to compete with Newell and Simon's (1976) physical symbol systems hypothesis. Unlike Newell and Simon's hypothesis, the dynamical hypothesis fails to provide necessary and sufficient conditions for cognition. Furthermore, imprecision in the statement of the dynamical hypothesis renders it unfalsifiable.

Abstract:
Physically based space planning is a means for automating the conceptual design process by applying the physics of motion to space plan elements. This methodology provides for a responsive design process, allowing a designer to easily make decisions whose consequences propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the design. The primary assumption is that a digital design tool based on a physics paradigm can facilitate the architectural space planning process. The hypotheses are that Newtonian dynamics can be used 1) to define mechanical metaphors to represent the elements in an architectural space plan, 2) to compute architectural space planning solutions, and 3) to interact with architectural space plans. I show that space plan elements can be represented as physical masses, that design objectives can be represented using mechanical metaphors such as springs, repulsion fields, and screw clamps, that a layout solution can be computed by using these elements in a dynamical simulation, and that the user can interact with that solution by applying forces that are also models of the same mechanical objects. I present a prototype software application that successfully implements this approach. A subjective evaluation of this prototype reveals that it demonstrates a feasible process for producing space plans, and that it can potentially improve the design process because of the quality of the manipulation and the enhanced opportunities for design exploration it provides to the designer. I found that an important characteristic of this approach is that representation, computation, and interaction are all defined using the same paradigm. This contrasts with most approaches to automated space planning, where these three characteristics are usually defined in completely different ways. Also emerging from this work is a new cognitive theory of design titled 'dynamical design imagery,' which proposes that the elements in a designer's mental imagery during the act of design are dynamic in nature and act as a dynamical system, rather than as static images that are modified in a piecewise algorithmic manner.

Full text
Abstract:
A review of the literature applying Multilayer Perceptron (MLP) based Artificial Neural Networks (ANNs) to market forecasting leads to three observations: 1) It is clear that simple ANNs, like other nonlinear machine learning techniques, are capable of approximating general market trends 2) It is not clear to what extent such forecasted trends are reliably exploitable in terms of profits obtained via trading activity 3) Most research with ANNs reporting profitable trading activity relies on ANN models trained over one fixed interval which is then tested on a separate out-of-sample fixed interval, and it is not clear to what extent these results may generalize to other out-of-sample periods. Very little research has tested the profitability of ANN models over multiple out-of-sample periods, and the author knows of no pure ANN (non-hybrid) systems that do so while being dynamically retrained on new data. This thesis tests the capacity of MLP type ANNs to reliably generate profitable trading signals over rolling training and testing periods. Traditional error statistics serve as descriptive rather than performance measures in this research, as they are of limited use for assessing a system’s ability to consistently produce above-market returns. Performance is measured for the ANN system by the average returns accumulated over multiple runs over multiple periods, and these averages are compared with the traditional buy-and-hold returns for the same periods. In some cases, our models were able to produce above-market returns over many years. These returns, however, proved to be highly sensitive to variability in the training, validation and testing datasets as well as to the market dynamics at play during initial deployment. We argue that credible challenges to the Efficient Market Hypothesis (EMH) by machine learning techniques must demonstrate that returns produced by their models are not similarly susceptible to such variability.

González, Gómez Andrés. "Nonlinear dynamics and smooth transition models." Doctoral thesis, Handelshögskolan i Stockholm, Ekonomisk Statistik (ES), 2004. http://urn.kb.se/resolve?urn=urn:nbn:se:hhs:diva-541.

Full text
Abstract:
During the last few years nonlinear models have been a very active area of econometric research: new models have been introduced and existing ones generalized. To a large extent, these developments have concerned models in which the conditional moments are regime-dependent. In such models, the different regimes are usually linear and the change between them is governed by an observable or unobservable variable. These specifications can be useful in situations in which it is suspected that the behaviour of the dependent variable may vary between regimes. A classical example can be found the business cycle literature where it is argued that contractions in the economy are not only more violent but also short-lived than expansions. Unemployment, which tends to rise faster during recessions than decline during booms, constitutes another example. Two of the most popular regime-dependent models are the smooth transition and the threshold model. In both models cases the transition variable is observable but the specification of the way in which the model changes from one regime to the other is different. Particularly, in the smooth transition model the change is a continuous whereas in the threshold model it is abrupt. One of the factors that has influenced the development of nonlinear models are improvements in computer technology. They have not only permitted an introduction of more complex models but have also allowed the use of computer-intensive methods in hypothesis testing. This is particularly important in nonlinear models because there these methods have proved to be practical in testing statistical hypothesis such as linearity and parameter constancy. In general, these testing situation are not trivial and their solution often requires computer-intensive methods. In particular, bootstrapping and Monte Carlo testing are now commonly used. In this thesis the smooth transition model is used in different ways. In the first chapter, a vector smooth transition model is used as a device for deriving a test for parameter constancy in stationary vector autoregressive models. In the second chapter we introduce a panel model whose parameters can change in a smooth fashion between regimes as a function of an exogenous variable. The method is used to investigate whether financial constraints affect firms' \ investment decisions. The third chapter is concern with linearity testing in smooth transition models. New tests are introduced and Monte Carlo testing techniques are shown to be useful in achieving control over the size of the test. Finally, the last chapter is devoted to the Smooth Permanent Surge model. This is a nonlinear moving average model in which a shock can have transitory or permanent effects depending on its sign and magnitude. Test for linearity and random walk hypothesis are introduced.

ENGLISH ABSTRACT: The World Values Survey has made a significant contribution to research in the field of values and value change, but a large amount of the research has been fashioned in a manner to tap values in industrialized and western states, rendering the theoretical models of explanation less than relevant for developing nations. This study aims to advance an understanding of value change within the South African context, particularly in light of the expansive political, social and economic changes to have transpired since 1990, whilst simultaneously addressing this issue of a lack of universal theory to understand value change. Primary amongst the theoretical frameworks addressing this issue of value change has been Ronald Inglehart's theory of a shift towards increased post-materialism in economically viable democratic countries. By subjecting survey data regarding value priorities from the South African rounds of the 1991, 1995 and 2001 World Values Survey to statistical analysis, the hypothesis of a similar situation in South Africa will be tested. After evaluating whether South Africa concurs with the post-materialist shift hypothesis, a unique dimension, including pre-materialist values, will be utilized in an attempt to establish whether South Africa has undergone any value change. This dimension is employed in the analysis of the 1995 and 2001 South African data, and whilst the value shift hypothesis promulgated by Inglehart appears largely unconcurred, an overall trend away from pre-materialism towards increased mixed type value priorities, with an ever so slight increase in materialists, has become evident. Although South Africa's value configuration is displaying an increasing convergence towards more moderate value orientations, most of the dynamics of change are manifesting themselves amongst and across various population sub-groups. South Africa's values are therefore undergoing relatively dramatic fluctuations, mainly reflected when the data are disaggregated for the various population sub-groups, the results indicating that longitudinal analysis along the pre-materialist/materialist continuum continues to be a more appropriate tool for tapping South Africa's underlying values. The consequences of these findings, for democratic consolidation, future political conflict, value change determinants and the appropriateness of this model for developing countries, will be assessed in detail. Consequently, by conducting these analyses, this research essay attempts to situate a global, but still largely Western theory, in a South African and developing world context. It thereby attempts to contribute towards filling a knowledge gap concerning the direction, degree and nature of the dynamics of value change.
AFRIKAANSE OPSOMMING: Hoewel die Wêreld Waardestudie sedert 1981 'n noemenswaardige bydrae gemaak het tot navorsing rakende waardes en waardeverandering, was dit tot dusver hoofsaaklik gefokus op waardes van geindustrialiseerde en westerse state. Dié fokus, het die studie grootliks van sy verklarende bruikbaarheid vir ontwikkelende lande ontneem. In hierdie opdrag sal daar gepoog word om die waardeveranderinge van Suid-Afrikaners, in die lig van die politieke- en ekonomiese omwentelinge sedert 1990, te beskryf. Dit sal gedoen word tesame met die aanspreek van die kwessie rondom die gebrek aan 'n universele teorie waarmee waardeverandering verklaar kan word. Ronald Inglehart se teorie, wat 'n skuif na post-materialistiese waardes in ekonomiese lewensvatbare state postuleer, was tot dusver die mees prominente teoretiese raamwerk wat waardeveranderinge beskryf het. Deur middel van die analise van die 1991, 1995 en 2001 data van die Suid-Afrikaanse rondte van die Wêreld Waardestudie, sal daar gepoog word om dié hipotese binne die plaaslike konteks te toets. Hierna sal 'n unieke dimensie, wat prematerialistiese waardes insluit, gebruik word om vas te stelof Suid-Afrikaners enige verandering in hul waarde oriëntasies ondergaan het. Hierdie dimensie is by die 1995 en 2001 studies ingesluit, en hoewel die resultate nie heeltemalooreenstem met Inglehart se hipotese nie, was daar 'n neiging weg van pre-materialisme in die rigting van meer gemenge waarde prioriteite, sowel as 'n baie klein toename in die aantal materialiste, merkbaar. Suid- Afrikaners blyk te beweeg in die rigting van meer gematigde waarde oriëntasies, en meeste van hierdie neigings manifesteer ditselfbinne en tussen die verskeie bevolkingsgroepe. Suid-Afrikaanse waardes ondergaan dus, in relatiewe terme, dramatiese veranderinge, wat veral na vore kom wanneer data vir die onderskeie bevolking sub-groepe afsonderlik geanaliseer word. Die resultate bevestig dat longitudinale analise in terme van 'n prematerialistiese/ materialistiese kontinuum steeds die beste metode is om waardeverandering binne die Suid-Afrikaanse konteks te meet. Die implikasies van hierdie bevindinge vir demokratiese konsolidasie, toekomstige politieke konflik, waardeveranderinge, en die toepaslikheid van die modelop ontwikkelende lande, sal in detail bespreek word. Hierdie studie poog gevolglik om 'n universele, maar hoofsaaklik steeds Westerse, teorie in 'n Suid- Afrikaanse en ontwikkelende staat perspektief te plaas. Daar word gehoop dat sodanige studie sal bydra om bestaande tekortkominge rakende die rigting, graad, en aard, van waardeveranderinge aan te spreek.

Abstract:
From small-scale food-sharing among hunter-gatherers to large-scale institutions in modern industrial societies, cooperation is central to human success. This thesis focuses on the former, exploring cooperative dynamics among the Agta, a Filipino hunter-gatherer population. I develop a novel experimental approach to exploring hunter-gatherer cooperative behaviour which simultaneously assesses the amount individuals cooperate and who they cooperate with. In contrast to much previous experimental literature, this non-anonymous design permits tests of specific theories for the evolution of cooperation, including: kin selection (cooperating with related individuals); reciprocity (cooperating with others who cooperate in return); and tolerated theft/demand sharing (taking from those with more resources), among other adaptive hypotheses. Using two experimental games – one exploring giving behaviour (donating resources to others) and another exploring demand sharing behaviour (taking resources from others) – I find that individuals from camps with a greater probability of repeated interactions give more to and take less from others. When individuals give to others it is directed towards kin and reciprocating partners, while when individuals take they do so from those with more resources, regardless of kinship or reciprocity. As predicted by theoretical models, this suggests that reciprocal transfers occur when interactions are repeated, while demand sharing occurs when repeated interactions are less likely. Differences in the frequency of repeated interactions may therefore explain some cross-cultural variation in forager food-sharing practices. This thesis also explores the effects of reputation on cooperative and interaction networks, finding that many aspects of forager social networks may reflect the trade of commodities in biological markets. Additionally, assessment of the ontogenetic roots of Agta cooperative behaviour suggests that 3 who children cooperate with, but not overall levels of cooperation, change over childhood in ways which are consistent with adaptive evolutionary hypotheses. These findings provide an insight into the evolutionary and ecological roots of hunter-gatherer cooperation.

Full text
Abstract:
Assembly lines are no longer systems designed to produce as much as possible at the lower cost. Nowadays several factors such as mass customization and variation in demand have led the manufacturers to consider the flexibility of the assembly systems as one of the most important facts to take into account when designing an assembly line. In this context, this study attempts to test a new paradigm of the workload balance, which is based on a dynamic allocation of the assembly operations. In order to test the hypothesis, a real assembly system of engines has been used as a base model to implement the new approach. The work developed, uses the simulation as a means to carry out the study, which has required the development of several simulation scenarios. The hypothesis has been studied from two different approaches; on one hand a total dynamic allocation of assembly operations, which was expected to cause a wide operational range of the stations. On the other hand, the second approach implements a flow control which aims to reduce the operational range and workload fluctuations. The results obtained show a significant improvement of the system performance in comparison with the current assembly line. It has been found that any improvement implemented in the system is directly reflected in the total performance of the line, regardless if the improvement is made in a system constraint. Moreover, the results have proven a better response of the system to changes in the frequency of models production.  Finally, based on the results, this study suggests several paths of future work in order to acquire the needed information to implement the hypothesis in the real world context.

Full text
Abstract:
Among-individual variation in resource use is pervasive and may have ecosystem-wide effects. This variation between individuals can affect population niche breadth. My study determined if niche breadth was best explained by dispersal of individuals from locations with different prey resources driven by ecosystem level disturbance regimes or competition among individuals inhabiting a site, resulting in dietary partitioning. I used structural equation modeling to examine the direct and indirect effects of several environmental variables spanning gradients of disturbance, competition strength, and food availability on niche breadth of the Eastern Mosquitofish (Gambusia holbrooki). I evaluated two complementary models 1) allowing for only direct effects of disturbance on niche breadth and 2) limiting effects of disturbance on niche breadth to indirect effects via food availability and competitor densities. The partitioning hypothesis excluding direct effects of disturbance on niche breadth was best supported by my data.

Abstract This book contains 23 chapters divided into seven parts. Part I reviews the key hypotheses in invasion ecology that invoke biotic interactions to explain aspects of plant invasion dynamics; and reviews models, theories and hypotheses on how invasion performance and impact of introduced species in recipient ecosystems can be conjectured according to biotic interactions between native and non-native species. Part II deals with positive and negative interactions in the soil. Part III discusses mutualistic interactions that promote plant invasions. Part IV describes antagonistic interactions that hinder plant invasions, while part V presents the consequences of plant invasions for biotic interactions among native species. In part VI, novel techniques and experimental approaches in the study of plant invasions are shown. In the last part, biotic interactions and the management of ecosystems invaded by non-native plants are discussed.

Abstract:
The volume contains the commented edition of the Devisement dou monde based on the Berlin Staatsbibliothek - Preußischer Kulturbesitz Codex, Hamilton 424. The Hamilton 424 Codex, transcribed in Venice in the second half of the fifteenth century, contains the translation of a Latin model (whose features can be partially reconstructed virtually starting from some translation errors) and is the only known witness of V. Due to its characteristics, V represents a crucial point in the definition of the transmission dynamics of Polo’s book: its readings are confirmed, often in a broader form, by the Latin version known as Z. V strengthens the hypothesis that, after returning to Venice, Marco Polo modified the text written with Rustichello da Pisa in Genoa. Actually, version V represents the first step of this long process of rewriting, which probably occurred in several phases. This volume includes an introduction, the text edition, a textual commentary, as well as an index. A second and forthcoming volume will contain the linguistic analysis and glossary.

Abstract:
The flow properties and dynamical behavior of fluid in a nanochannel were investigated by nonequilibrium molecular dynamics simulation. First of all, the locale distribution of molecules in the channel is found to be strongly inhomogeneous compared to the bulk fluid. In the vicinity of the wall, portion of the fluid molecules are absorbed on the surface of wall due to the strong interaction of the atoms between the wall and liquid, so that the fluid density in the contact region would be much larger than one of the bulk fluid. But in the other region, the local density value approaches one of the bulk fluids with the increasing distance from the wall. This oscillatory behavior of density resulted in different motion behavior of molecules in the different region of nanochannel. The molecular behavior in the interfacial region is remarkably different from those of fluid atoms in the center of channel and wall atoms, which posses both the motion properties of bulk liquids and a solid atom. At the molecular level, macroscopic continuum hypothesis failed, that is, the results predicted by the Navier-Stoke equations deviate from the simulation data adopted by molecular dynamics simulation. In the paper, the velocity profiles for the channels with different width were plotted, which demonstrated that the time-averaged velocity profiles was not quadratic when the channel width was less than 10 molecular diameters. But on the other cases, the velocity profiles will agree well with the analytical solution based on the NS theory. The molecular dynamics simulation method can withdraw the important microscopical information from the simulation process, which benefit to analyze the flow mechanism at such length scale channel.

Abstract:
Dimensional Analysis (DA) is a tool often used to relate models and specimens to the actual product or system based on the hypothesis that the two regimes follow the same physical laws and are hence dimensionally equivalent. While this has been a conventional use of the process, we extend the technique to dynamic systems to develop state equations that allow for design studies and optimization. A methodical approach is detailed coupled with an example of a toy water-rocket assembly. A modified methodology (heuristic) is also discussed to condense non-monomial basis systems using simple physical laws and a novel reduction process. Experimental verification is provided to complement the analysis procedure. Efficacy of the process is highlighted in comparison with the conventional close-form approach.

Abstract:
Information-theoretical notions of causality provide a model-free approach to identification of the magnitude and direction of influence among sub-components of a stochastic dynamical system. In addition to detecting causal influences, any effective test should also report the level of statistical significance of the finding. Here, we focus on transfer entropy, which has recently been considered for causality detection in a variety of fields based on statistical significance tests that are valid only in the asymptotic regime, that is, with enormous amounts of data. In the interest of applications with limited available data, we develop a non-asymptotic theory for the probability distribution of the difference between the empirically-estimated transfer entropy and the true transfer entropy. Based on this result, we additionally demonstrate an approach for statistical hypothesis testing for directed information flow in dynamical systems with a given number of observed time steps.

Full text
Abstract:
A number of previous works have suggested that in some cases the interaction between shaft and bladed disk modes could significantly modify the dynamics of the whole assembly i.e. the bladed disks mounted on a flexible shaft. This paper presents the application of a previously published reduced-order modeling technique to the dynamical modeling of a real two stage gas turbine, including the bladed disks and the shaft. In the resulting reduce order model, mistuning is included in the bladed disk models and the shaft is modeled using beam finite elements according to the classical rotordynamic approach. Generation of finite element parent model for the real turbine is presented and discussed as well as simplifications used in order to generate the reduced order model. Comparisons are made between the reduced model and the full finite element solution for free response frequencies and mode shapes in order to assess the methodology and to evaluate the impact of simplifying hypothesis considered in model generation. Finally, this work also shows interaction between shaft modes and bladed disk modes, therefore confirming that stage independent analysis might not be adequate for predicting the global dynamic response of some turbomachinery rotors.

Full text
Abstract:
Abstract Measurements revealed the contribution of multiple traveling waves to the flutter vibrations of bladed disks. Saturated flutter vibration, whether in this multi-wave or in its better-understood single-wave form, is a nonlinear phenomenon. However, it is still not understood of what physical origin the relevant nonlinearities are, and under what conditions single-wave or multi-wave flutter vibration occurs. Recent theoretical work suggests that multi-wave flutter vibration can be explained by strongly nonlinear frictional inter-blade coupling. The verity of this hypothesis is strictly limited by the simplicity of the considered model, namely a cyclic chain of seven oscillators with frictional coupling and rather unrealistic aeroelastic behavior. In the present work, it is demonstrated that nonlinear dynamical contact interactions at tip shrouds are a likely cause for the observed multi-wave flutter vibration. To this end, a more realistic structural turbine blade row model with a more realistic aeroelastic behavior is considered. Some insight into its intriguing dynamics, dependence of limit states on initial conditions and eigenvalue placement is provided. For instance, it is shown that there is an intimate relation between internal combination resonance conditions of certain traveling wave modes and the spectral content of single- and multi-wave flutter oscillations.

Full text
Abstract:
In this paper, a damage identification method called local flow variation is introduced. It is a practical implementation of a phase space warping concept. A hierarchical dynamical system is considered where a slow-time damage process causes drifts in the parameters of fast-time system describing measurable response of a structure. The method is based on the hypothesis that the probability distribution function of the fast-time trajectory in its phase space is a function of damage state. In this method, an ensemble of estimated expectations of trajectory in different locations of the reconstructed phase space is used as a damage feature vector. Using these feature vectors, damage identification is realized by a smooth orthogonal decomposition. An experiment is conducted to validate the method. A two dimensional slow-time damage process is identified from experimental fast-time data. Although damage identification through the local flow variation is not as accurate as trough phase space warping, the required computing time is about two-orders-of-magnitude shorter.

Abstract:
In train collisions, multi-level rail passenger vehicles can deform in modes that are different from the behavior of single level cars. The deformation in single level cars usually occurs at the front end during a collision. In one particular incident, a cab car buckled laterally near the back end of the car. The buckling of the car caused both lateral and vertical accelerations, which led to unanticipated injuries to the occupants. A three-dimensional collision dynamics model of a multi-level passenger train has been developed to study the influence of multi-level design parameters and possible train configuration variations on the reactions of a multi-level car in a collision. This model can run multiple scenarios of a train collision. This paper investigates two hypotheses that could account for the unexpected mode of deformation. The first hypothesis emphasizes the non-symmetric resistance of a multi-level car to longitudinal loads. The structure is irregular since the stairwells, supports for tanks, and draglinks vary from side to side and end to end. Since one side is less strong, that side can crush more during a collision. The second hypothesis uses characteristics that are nearly symmetric on each side. Initial imperfections in train geometry induce eccentric loads on the vehicles. For both hypotheses, the deformation modes depend on the closing speed of the collision. When the characteristics are non-symmetric, and the load is applied in-line, two modes of deformation are seen. At low speeds, the couplers crush, and the cars saw-tooth buckle. At high speeds, the front end of the cab car crushes, and the cars remain in-line. If an offset load is applied, the back stairwell of the first coach car crushes unevenly, and the cars saw-tooth buckle. For the second hypothesis, the characteristics are symmetric. At low speeds, the couplers crush, and the cars remain in-line. At higher speeds, the front end crushes, and the cars remain in-line. If an offset load is applied to a car with symmetric characteristics, the cars will saw-tooth buckle.

Abstract:
This project objective evaluated the potential of improving linked weather-and-mobility model predictions by blending soil moisture observations from a Cosmic-ray Soil Moisture Observing System (COSMOS) sensor with weather-informed predictions of soil moisture and soil strength from the Geospatial Weather-Affected Terrain Conditions and Hazards (GeoWATCH). Assimilating vehicle-borne COSMOS observations that measure local effects model predictions of soil moisture offered potential to produce more accurate soil strength and vehicle mobility forecast was the hypothesis. This project compared soil moisture observations from a COSMOS mobile sensor driven around an area near Iowa Falls, IA, with both GeoWATCH soil moisture predictions and in situ probe observations. The evaluation of the COSMOS rover data finds that the soil moisture measurements contain a low measurement bias while the GeoWATCH estimates more closely matched the in situ data. The COSMOS rover captured a larger dynamic range of soil moisture conditions as compared to GeoWATCH, capturing both very wet and very dry soil conditions, which may better flag areas of high risk for mobility considerations. Overall, more study of the COSMOS rover is needed to better understand sensor performance in a variety of soil conditions to determine the feasibility of assimilating the COSMOS rover estimates into GeoWATCH.
