To estimate future water availability in this region, it is necessary to use climate projections to estimate the future glacier extent and volume. In this study, we evaluate the impact of uncertainty in climate change projections on the future glacier extent in the Amu and Syr Darya river basins. To this end we use the latest climate change projections generated for the upcoming IPCC report (CMIP5) and, for comparison, projections used in the fourth IPCC assessment (CMIP3). With these projections we force a regionalized glacier mass balance model, and estimate changes in the basins' glacier extent as a function of the glacier size distribution in the basins and projected temperature and precipitation. This glacier mass balance model is specifically developed for implementation in large scale hydrological models, where the spatial resolution does not allow for simulating individual glaciers and data scarcity is an issue. Although the CMIP5 ensemble results in greater regional warming than the CMIP3 ensemble and the range in projections for temperature as well as precipitation is wider for the CMIP5 than for the CMIP3, the spread in projections of future glacier extent in Central Asia is similar for both ensembles. This is because differences in temperature rise are small during periods of maximum melt (July–September) while differences in precipitation change are small during the period of maximum accumulation (October–February). However, the model uncertainty due to parameter uncertainty is high, and has roughly the same importance as uncertainty in the climate projections. Uncertainty about the size of the decline in glacier extent remains large, making estimates of future Central Asian glacier evolution and downstream water availability uncertain."}],"keyword":["General Earth and Planetary Sciences","General Engineering","General Environmental Science"],"year":"2013","main_file_link":[{"url":"https://doi.org/10.5194/hess-17-3661-2013","open_access":"1"}],"scopus_import":"1","article_processing_charge":"No","volume":17,"citation":{"ieee":"A.

However, the reliability of their projections strongly depends on the quality and quantity of data that are available for parameter estimation, model calibration and validation, as well as on the accuracy of climate change projections. In this study the physically oriented, glaciohydrological model TOPKAPI-ETH is used to simulate future changes in snow, glacier, and runoff from the Hunza River Basin in northern Pakistan. Three key sources of model uncertainty in future runoff projections are compared: model parameters, climate projections, and natural climate variability. A novel approach, applicable also to ungauged catchments, is used to determine which model parameters and model components significantly affect the overall model uncertainty. We show that the model is capable of reproducing streamflow and glacier mass balances, but that all analyzed sources of uncertainty significantly affect the reliability of future projections, and that their effect is variable in time and in space. The effect of parametric uncertainty often exceeds the impact of climate uncertainty and natural climate variability, especially in heavily glacierized subcatchments. The results of the uncertainty analysis allow detailed recommendations on network design and the timing and location of field measurements, which could efficiently help to reduce model uncertainty in the future.","lang":"eng"}],"oa_version":"Published Version","publication_status":"published","_id":"12639","title":"Sources of uncertainty in modeling the glaciohydrological response of a Karakoram watershed to climate change","intvolume":"        49","oa":1,"publisher":"American Geophysical Union","publication_identifier":{"issn":["0043-1397"]},"author":[{"last_name":"Ragettli","first_name":"S.","full_name":"Ragettli, S."},{"full_name":"Pellicciotti, Francesca","first_name":"Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","last_name":"Pellicciotti"},{"last_name":"Bordoy","first_name":"R.","full_name":"Bordoy, R."},{"full_name":"Immerzeel, W.

Here, we use results from the latest ensemble of climate models in combination with a high-resolution glacio-hydrological model to assess the hydrological impact of climate change on two climatically contrasting watersheds in the Greater Himalaya, the Baltoro and Langtang watersheds that drain into the Indus and Ganges rivers, respectively. We show that the largest uncertainty in future runoff is a result of variations in projected precipitation between climate models. In both watersheds, strong, but highly variable, increases in future runoff are projected and, despite the different characteristics of the watersheds, their responses are surprisingly similar. In both cases, glaciers will recede but net glacier melt runoff is on a rising limb at least until 2050. In combination with a positive change in precipitation, water availability during this century is not likely to decline. We conclude that river basins that depend on monsoon rains and glacier melt will continue to sustain the increasing water demands expected in these areas10.","lang":"eng"}],"keyword":["General Earth and Planetary Sciences"],"year":"2013","oa_version":"None","title":"Rising river flows throughout the twenty-first century in two Himalayan glacierized watersheds","_id":"12640","publication_status":"published","intvolume":"         6","volume":6,"citation":{"ama":"Immerzeel WW, Pellicciotti F, Bierkens MFP.

In this paper, we test a simple thermodynamic model proposed by Greuell and Böhm in 1998 as an alternative, using a new dataset of air temperature measurements from along the flowline of Haut Glacier d’Arolla, Switzerland. The unmodified model performs little better than assuming a constant linear lapse rate. When modified to allow the ratio of the boundary layer height to the bulk heat transfer coefficient to vary along the flowline, the model matches measured air temperatures better, and a further reduction of the root-mean-square error is obtained, although there is still considerable scope for improvement.

In this paper, we test 13 clear-sky parameterizations combined with seven cloud corrections for all-sky atmospheric emissivity at one location on Haut Glacier d'Arolla. We also analyze the four seasons separately and conduct a cross-validation to test the parameters’ robustness. The best parameterization is the one by Dilley and O'Brien, B for clear-sky conditions combined with Unsworth and Monteith cloud correction. This model is also the most robust when tested in cross-validation. When validated at different sites in the southern Alps of Switzerland and north-western Italian Alps, all parameterizations show a substantial decrease in performance, except for one site, thus suggesting that it is important to recalibrate parameterizations of incoming longwave radiation for different locations. We argue that this is due to differences in the structure of the atmosphere at the sites. We also quantify the effect that the incoming longwave radiation parameterizations have on energy-balance melt modeling, and show that recalibration of model parameters is needed. Using parameters from other sites leads to a significant underestimation of melt and to an error that is larger than that associated with using different parameterizations. Once recalibrated, however, the parameters of most models seem to be stable over seasons and years at the location on Haut Glacier d'Arolla."}],"keyword":["Space and Planetary Science","Earth and Planetary Sciences (miscellaneous)","Atmospheric Science","Geophysics"],"intvolume":"       118","oa":1,"oa_version":"Published Version","_id":"12643","publication_status":"published","title":"A comparison of parameterizations of incoming longwave radiation over melting glaciers: Model robustness and seasonal variability","extern":"1","doi":"10.1002/jgrd.50277","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","citation":{"ista":"Juszak I, Pellicciotti F. 2013.

To minimize interference of the optical activation of channelrhodopsin-2 with the visual perception of the flies, we used a bistable variant called ChR2-C128S. By applying pulses of blue and yellow light, we first demonstrate electrophysiologically that lobula plate tangential cells can be activated and deactivated repeatedly with no evident change in depolarization strength over trials. We next show that selective optogenetic activation of HS cells elicits robust yaw head movements and yaw turning responses in fixed and tethered flying flies, respectively.","lang":"eng"}],"acknowledgement":"This work was supported by the Max Planck Society.

However, how these pathways are functionally specialized remains controversial. One study (Eichner et al., 2011) proposed that the L1-pathway evaluates only sequences of brightness increments (ON-ON), while the L2-pathway processes exclusively brightness decrements (OFF-OFF). Another study (Clark et al., 2011) proposed that each of the two pathways evaluates both ON-ON and OFF-OFF sequences. To decide between these alternatives, we recorded from motionsensitive neurons in flies in which the output from either L1 or L2 was genetically blocked. We found that blocking L1 abolishes ON-ON responses but leaves OFF-OFF responses intact. The opposite was true, when the output from L2 was blocked. We conclude that the L1 and L2 pathways are functionally specialized to detect ON-ON and OFF-OFF sequences, respectively."}],"year":"2013","day":"16","date_created":"2018-12-11T11:51:16Z","author":[{"id":"2BD278E6-F248-11E8-B48F-1D18A9856A87","last_name":"Jösch","first_name":"Maximilian A","full_name":"Maximilian Jösch","orcid":"0000-0002-3937-1330"},{"full_name":"Weber, Franz","last_name":"Weber","first_name":"Franz"},{"first_name":"Hubert","last_name":"Eichner","full_name":"Eichner, Hubert"},{"full_name":"Borst, Alexander","first_name":"Alexander","last_name":"Borst"}]},{"volume":38,"quality_controlled":0,"citation":{"ieee":"J.

Given an articulated character as input, the user iteratively creates an animation by sketching motion curves indicating how different parts of the character should move. For each motion curve, our framework creates an optimized mechanism that reproduces it as closely as possible. The resulting mechanisms are attached to the character and then connected to each other using gear trains, which are created in a semi-automated fashion. The mechanical assemblies generated with our system can be driven with a single input driver, such as a hand-operated crank or an electric motor, and they can be fabricated using rapid prototyping devices. We demonstrate the versatility of our approach by designing a wide range of mechanical characters, several of which we manufactured using 3D printing. While our pipeline is designed for characters driven by planar mechanisms, significant parts of it extend directly to non-planar mechanisms, allowing us to create characters with compelling 3D motions.

This introduces an anisotropy into the process, often as different accuracies in the tangential and normal directions, but also in terms of other parameters such as build speed or tensile strength and strain. We model this as an anisotropic cubic element. Our approach then finds a compromise between modeling each part of the shape individually in the best possible direction and using one direction for the whole shape part. In particular, we compute an orthogonal basis and consider only the three basis vectors as slice normals (i.e. fabrication directions). Then we optimize a decomposition of the shape along this basis so that each part can be consistently sliced along one of the basis vectors. In simulation, we show that this approach is superior to slicing the whole shape in one direction, only. It also has clear benefits if the shape is larger than the build volume of the available equipment.","lang":"eng"}],"author":[{"full_name":"Hildebrand, Kristian","first_name":"Kristian","last_name":"Hildebrand"},{"orcid":"0000-0001-6511-9385","full_name":"Bernd Bickel","first_name":"Bernd","last_name":"Bickel","id":"49876194-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Alexa","first_name":"Marc","full_name":"Alexa, Marc"}],"day":"01","date_created":"2018-12-11T11:55:46Z"},{"author":[{"full_name":"Papas, Marios","first_name":"Marios","last_name":"Papas"},{"first_name":"Christian","last_name":"Regg","full_name":"Regg, Christian"},{"full_name":"Jarosz, Wojciech","last_name":"Jarosz","first_name":"Wojciech"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","last_name":"Bickel","first_name":"Bernd","full_name":"Bernd Bickel","orcid":"0000-0001-6511-9385"},{"first_name":"Philip","last_name":"Jackson","full_name":"Jackson, Philip V"},{"full_name":"Matusik, Wojciech","first_name":"Wojciech","last_name":"Matusik"},{"last_name":"Marschner","first_name":"Steve","full_name":"Marschner, Steve"},{"full_name":"Groß, Markus S","first_name":"Markus","last_name":"Groß"}],"date_created":"2018-12-11T11:55:46Z","day":"01","abstract":[{"text":"We present a method for practical physical reproduction and design of homogeneous materials with desired subsurface scattering.

However, their movement and expressions are often limited due to mechanical constraints. In this paper, we propose a complete process for augmenting physical avatars using projector-based illumination, significantly increasing their expressiveness. Given an input animation, the system decomposes the motion into low-frequency motion that can be physically reproduced by the animatronic head and high-frequency details that are added using projected shading. At the core is a spatio-temporal optimization process that compresses the motion in gradient space, ensuring faithful motion replay while respecting the physical limitations of the system. We also propose a complete multi-camera and projection system, including a novel defocused projection and subsurface scattering compensation scheme. The result of our system is a highly expressive physical avatar that features facial details and motion otherwise unattainable due to physical constraints."}],"year":"2013","author":[{"full_name":"Bermano, Amit H","last_name":"Bermano","first_name":"Amit"},{"full_name":"Bruschweiler, Philipp","last_name":"Bruschweiler","first_name":"Philipp"},{"first_name":"Anselm","last_name":"Grundhöfer","full_name":"Grundhöfer, Anselm"},{"last_name":"Iwai","first_name":"Daisuke","full_name":"Iwai, Daisuke"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","last_name":"Bickel","first_name":"Bernd","full_name":"Bernd Bickel","orcid":"0000-0001-6511-9385"},{"full_name":"Groß, Markus S","first_name":"Markus","last_name":"Groß"}],"date_created":"2018-12-11T11:55:47Z","day":"01","publication":"ACM Transactions on Graphics","date_published":"2013-11-01T00:00:00Z","month":"11","intvolume":"        32","status":"public","type":"journal_article","issue":"6","title":"Augmenting physical avatars using projector-based illumination","date_updated":"2021-01-12T06:55:23Z","_id":"2111","publication_status":"published","extern":1,"publist_id":"4922","publisher":"ACM","doi":"10.1145/2508363.2508416","volume":32,"quality_controlled":0,"citation":{"chicago":"Bermano, Amit, Philipp Bruschweiler, Anselm Grundhöfer, Daisuke Iwai, Bernd Bickel, and Markus Groß. “Augmenting Physical Avatars Using Projector-Based Illumination.” <i>ACM Transactions on Graphics</i>.

However, it has not been incorporated into computer animation models of cloth. In this paper, we propose a model of internal friction based on an augmented reparameterization of Dahl's model, and we show that this model provides a good match to several important features of cloth hysteresis even with a minimal set of parameters. We also propose novel parameter estimation procedures that are based on simple and inexpensive setups and need only sparse data, as opposed to the complex hardware and dense data acquisition of previous methods. Finally, we provide an algorithm for the efficient simulation of internal friction, and we demonstrate it on simulation examples that show disparate behavior with and without internal friction."}],"author":[{"full_name":"Miguel, Eder","first_name":"Eder","last_name":"Miguel"},{"first_name":"Rasmus","last_name":"Tamstorf","full_name":"Tamstorf, Rasmus"},{"full_name":"Bradley, Derek J","first_name":"Derek","last_name":"Bradley"},{"last_name":"Schvartzman","first_name":"Sara","full_name":"Schvartzman, Sara C"},{"last_name":"Thomaszewski","first_name":"Bernhard","full_name":"Thomaszewski, Bernhard"},{"full_name":"Bernd Bickel","orcid":"0000-0001-6511-9385","id":"49876194-F248-11E8-B48F-1D18A9856A87","last_name":"Bickel","first_name":"Bernd"},{"full_name":"Matusik, Wojciech","first_name":"Wojciech","last_name":"Matusik"},{"full_name":"Marschner, Steve","first_name":"Steve","last_name":"Marschner"},{"first_name":"Miguel","last_name":"Otaduy","full_name":"Otaduy, Miguel A"}],"day":"01","date_created":"2018-12-11T11:55:47Z","date_published":"2013-11-01T00:00:00Z","month":"11","intvolume":"        32","publication":"ACM Transactions on Graphics","status":"public","type":"journal_article","issue":"6","_id":"2112","date_updated":"2021-01-12T06:55:23Z","publication_status":"published","title":"Modeling and estimation of internal friction in cloth"},{"date_created":"2018-12-11T11:55:47Z","day":"23","author":[{"last_name":"Rouiller","first_name":"Olivier","full_name":"Rouiller, Olivier"},{"last_name":"Bickel","id":"49876194-F248-11E8-B48F-1D18A9856A87","first_name":"Bernd","full_name":"Bernd Bickel","orcid":"0000-0001-6511-9385"},{"last_name":"Kautz","first_name":"Jan","full_name":"Kautz, Jan"},{"last_name":"Matusik","first_name":"Wojciech","full_name":"Matusik, Wojciech"},{"full_name":"Alexa, Marc","last_name":"Alexa","first_name":"Marc"}],"abstract":[{"text":"A new method fabricates custom surface reflectance and spatially varying bidirectional reflectance distribution functions (svBRDFs).
