Abstract:
AbstractHow does technology influence international negotiations? This article explores “track-change diplomacy,” that is, how diplomats use information and communication technology (ICT) such as word processing software and mobile devices to collaboratively edit and negotiate documents. To analyze the widespread but understudied phenomenon of track-change diplomacy, the article adopts a practice-oriented approach to technology, developing the concept of affordance: the way a tool or technology simultaneously enables and constrains the tasks users can possibly perform with it. The article shows how digital ICT affords shareability, visualization, and immediacy of information, thus shaping the temporality and power dynamics of international negotiations. These three affordances have significant consequences for how states construct and promote national interests; how diplomats reach compromises among a large number of states (as text edits in collective drafting exercises); and how power plays out in international negotiations. Drawing on ethnographic methods, including participant observation of negotiations between the European Union's member states, as well as in-depth interviews, the analysis casts new light on these negotiations, where documents become the site of both semantic and political struggle. Rather than delivering on the technology's promise of keeping track and reinforcing national oversight in negotiations, we argue that track-change diplomacy can in fact lead to a loss of control, challenging existing understandings of diplomacy.

Abstract:
Within the Mobility Choices (MC) project we have developed an app that allows users to record their travel behavior and encourages them to try out new means of transportation that may better fit their preferences. Tracks explicitly released by the users are anonymized and can be analyzed by authorized institutions. For recorded tracks, the freely available app automatically determines the segments with their transportation mode; analyzes the track according to the criteria environment, health, costs, and time; and indicates alternative connections that better fit the criteria, which can individually be configured by the user. In the second step, the users can edit their tracks and release them for further analysis by authorized institutions. The system is complemented by a Web-based analysis program that helps authorized institutions carry out specific evaluations of traffic flows based on the released tracks of the app users. The automatic transportation mode detection of the system reaches an accuracy of 97%. This requires only minimal corrections by the user, which can easily be done directly in the app before releasing a track. All this enables significantly more accurate surveys of transport behavior than the usual time-consuming manual (non-automated) approaches, based on questionnaires.

Abstract:
The ability of keeping a record of geospatial information, knowing how it changed over time, is crucial for landscape analysis and territorial government. Land management is still a problem. Many governmental databases are incomplete, and there is a lack of reliable information. Good land management implies having a tool that can keep track of all the information available about a certain property and its changes over time. In this paper, we propose a land management tool where managers access all the information on a certain parcel of land—its boundaries, the land registration, a map which verifies the landcover, and the historic of updates of territorial limits. With the proposed tool, it is possible to edit the information of any property, whether it is active or not—that is, to also edit properties that no longer exist today, but that the user wants to add information to, for legal or other reasons. Keeping track of data properties’ revision history is groundbreaking due to the fact it is not well developed in existing tools. We will look at Brazil as a use case, where land management is a critical problem.

Abstract:
Suppose, you want to implement a structured editor for some term type, so that the user can navigate through a given term and perform edit actions on subterms. In this case you are immediately faced with the problem of how to keep track of the cursor movements and the user's edits in a reasonably efficient manner. In a previous pearl, Huet (1997) introduced a simple data structure, the Zipper, that addresses this problem – we will explain the Zipper briefly in section 2. A drawback of the Zipper is that the type of cursor locations depends on the structure of the term type, i.e. each term type gives rise to a different type of location (unless you are working in an untyped environment). In this pearl, we present an alternative data structure, the web, that serves the same purpose, but that is parametric in the underlying term type. Sections 3–6 are devoted to the new data structure. Before we unravel the Zipper and explore the web, let us first give a taste of their use.

Abstract:
For the past few years, Internet of Things (IoT) has developed rapidly and been extensively used. However, its transmission security and privacy protection are insufficient, which limits the development of IoT to a certain extent. As a technology of IoT information transmission, anonymous communication technology comes into being as an important means to ensure the security of healthcare data, which can better protect users’ privacy in some ways. Nowadays, a variety of attack techniques for anonymous communication systems have been proposed by the academic community to track senders and receivers or discover communications between two users. Thus, the MSFA (Multiple System Fingerprint Attack) scheme for anonymous communication systems is presented in this paper where the MSFA scheme architecture, implementation in the Tor environment, and experimental data processing are described. Through a comparative analysis between two traces of visiting the same website based on the edit distance, it is shown that the longer the length of the site traffic data, the greater the edit distance of the site access traffic and the larger the range.

Abstract:
A city may have multiple CityGML documents recorded at different times or surveyed by different users. To analyse the city’s evolution over a given period of time, as well as to update or edit the city model without negating modifications made by other users, it is of utmost importance to first compare, detect and locate spatio-semantic changes between CityGML datasets. This is however difficult due to the fact that CityGML elements belong to a complex hierarchical structure containing multi-level deep associations, which can basically be considered as a graph. Moreover, CityGML allows multiple syntactic ways to define an object leading to syntactic ambiguities in the exchange format. Furthermore, CityGML is capable of including not only 3D urban objects’ graphical appearances but also their semantic properties. Since to date, no known algorithm is capable of detecting spatio-semantic changes in CityGML documents, a frequent approach is to replace the older models completely with the newer ones, which not only costs computational resources, but also loses track of collaborative and chronological changes. Thus, this research proposes an approach capable of comparing two arbitrarily large-sized CityGML documents on both semantic and geometric level. Detected deviations are then attached to their respective sources and can easily be retrieved on demand. As a result, updating a 3D city model using this approach is much more efficient as only real changes are committed. To achieve this, the research employs a graph database as the main data structure for storing and processing CityGML datasets in three major steps: mapping, matching and updating. The mapping process transforms input CityGML documents into respective graph representations. The matching process compares these graphs and attaches edit operations on the fly. Found changes can then be executed using the Web Feature Service (WFS), the standard interface for updating geographical features across the web.

Abstract:
Abstract Summary Skyline is a Windows application for targeted mass spectrometry method creation and quantitative data analysis. Like most graphical user interface (GUI) tools, it has a complex user interface with many ways for users to edit their files which makes the task of logging user actions challenging and is the reason why audit logging of every change is not common in GUI tools. We present an object comparison-based approach to audit logging for Skyline that is extensible to other GUI tools. The new audit logging system keeps track of all document modifications made through the GUI or the command line and displays them in an interactive grid. The audit log can also be uploaded and viewed in Panorama, a web repository for Skyline documents that can be configured to only accept documents with a valid audit log, based on embedded hashes to protect log integrity. This makes workflows involving Skyline and Panorama more reproducible. Availability and implementation Skyline is freely available at https://skyline.ms. Supplementary information Supplementary data are available at Bioinformatics online.

Abstract:
We propose a set of path planning tools including path generator, cost map generator, and path editor for racing games. The user can define the race by providing a racetrack as a 3D model and weights of the devised turn and heuristic functions in our system. Then, the proposed cost map generator automatically generates necessary information of the racetrack including cost map and distance to finish of any position on the race track. Different from the traditional A* problem, in our research the obstacles are dynamic and there are multiple sources and destinations. Our approach generates the path of each racer on the basis of time slots to which the path finding method applies on the fly. To further guarantee the quality of the path, we implement path smoothing using a Gaussian filter and provide an off-line path editor that allows users to edit the path in time-space domain intuitively, flexibly, and effectively. Our tools have been verified in a horse racing game to generate natural racer behaviors, demonstrating realistic and exciting racing.

Abstract:
Big data bioinformatics aims at drawing biological conclusions from huge and complex biological datasets. Added value from the analysis of big data, however, is only possible if the data is accompanied by accurate metadata annotation. Particularly in high-throughput experiments intelligent approaches are needed to keep track of the experimental design, including the conditions that are studied as well as information that might be interesting for failure analysis or further experiments in the future. In addition to the management of this information, means for an integrated design and interfaces for structured data annotation are urgently needed by researchers. Here, we propose a factor-based experimental design approach that enables scientists to easily create large-scale experiments with the help of a web-based system. We present a novel implementation of a web-based interface allowing the collection of arbitrary metadata. To exchange and edit information we provide a spreadsheet-based, humanly readable format. Subsequently, sample sheets with identifiers and metainformation for data generation facilities can be created. Data files created after measurement of the samples can be uploaded to a datastore, where they are automatically linked to the previously created experimental design model.

Abstract Objectives This note describes a free online portal (www.therandomiser.co.uk) that allows researchers to design randomised controlled trials and then delegate the random assignment process to pracademics delivering the experiment. Methods Observation of the use of this tool in repeated randomised trials in police agencies. Findings Researchers are able to design RCTs using the online portal, which offers many ways to customise the experimental design. Results are downloadable in excel or plain text format. Researchers can grant access to treatment providers, enabling them to log in securely, enter identifiers for cases, and assign different treatments to each case. Email notifications of assignment can be sent to designated list of recipients who can track the allocation of treatments. This tool delivers this functionality at zero cost and at the time of writing is being used by 78 researchers, who have set up 70 experiments that have processed 5778 randomisations. Conclusions TheRandomiser has been used in multiple experiments with feedback suggesting it is a powerful and user-friendly tool. The ability to deliver trickle-flow randomisation with high degrees of researcher control are attractive, as is the ability to edit an unlimited number of qualification questions prior to randomisation.

Abstract:
In the early days of home computing, writing music was as much a technical as a creative process. This chapter explores how the launch of a software music package, Ultimate Soundtracker, for Commodore’s Amiga created a new, symbolic way to compose and edit music. It was sample-based and structured music using a grid-style interface that could be navigated using the computer keyboard, and its music files distributed both, making it easy to share—and copy—others’ musical ideas. This ‘open-source’ approach allowed nonprogrammers and nonmusicians to experiment with music making and for the sound to promulgate. This was also the period from which the term ‘chiptune’ emerged; the Amiga’s sample-based chipset allowed it to create other sounds beside raw electronic waveforms, and chiptune was used to highlight tracks written in the 8-bit sound chip style.

Abstract:
AbstractClinical tractography is a challenging problem in diffusion tensor imaging (DTI) due to persistent validation issues. Geodesic tractography, based on a shortest path principle, is conceptually appealing, but has not produced convincing results so far. A major weakness is its rigidity with respect to candidate tracts it is capable of producing given a pair of endpoints, showing a tendency to produce false positives (such as shortcuts) and false negatives (e.g. if a shortcut supplants the correct solution). We propose a new geodesic paradigm that appears to overcome these problems, making a step towards semi-automatic clinical use. To this end we couple the DTI tensor field to a family of Riemannian metrics, governed by control parameters. In practice these parameters may allow for edits by an expert through manual selection among multiple tract suggestions, or for bringing in a priori knowledge. In this paper, however, we consider an automatic, evidence-driven procedure to determine optimal controls and corresponding tentative tracts, and illustrate the role of edits to remediate erroneous defaults.

Abstract:
Reading Edith Wharton’s Old New York through the genre of regionalism reveals the complexity of her cosmopolitanism, and strengthens the case for reading the volume as a unified work. The chapter discusses relevant aspects of the cultural history of the decades in which the four stories are set (such as the associations of tuberculosis in “False Dawn” and the ormolu clock in “The Old Maid”) and reviews the early publication history of each story and the collection. Close readings trace how Wharton connects and contrasts the United States and Europe (especially New York City and Italy) and puts their correspondences with historical eras into play—challenging received notions of progress and the assumption that cultivated taste correlates with integrity. The chapter argues that the way Old New York maps time onto place enables the projection of alternative values within a work that remains publishable and legible in its own moment.

Full text
Abstract:
This chapter reconsiders Edith Sitwell’s only novel, I Live under a Black Sun, as Gothic fiction opening up a political reading of British colonialism and women’s labor. When read as citing and rewriting Gothic tropes, the earnest moralizing in the text becomes more nuanced. The ostensibly tidy allegorizing of the salvific power of Christian brotherly love is complicated by the eruption of disavowed sites of material and emotional labor that underwrites such a narrative. The chapter argues for the need to look at Sitwell as a thinker in her own right who dramatized her own strangeness as a way of critiquing the “normalcy” and mass politics around her. Gothic fiction tropes permitted her to offer a secret history of her historical moment, connecting her strangeness to a history of writers with whom she might feel professional kinship while emphasizing her own unique qualities. While she was not interested in feminist political action, Sitwell was concerned with problems of women’s labor in ways we might trace in other mid-century women’s writing that has been dismissed as apolitical or reactionary.

Abstract:
Albums kept by Sara Coleridge, Edith May Southey, and Dora Wordsworth between the early 1820s and late 1840s show that that although the Wordsworth circle daughters’ access to their famous fathers’ literary networks resulted in books exceptionally rich in album verse by well-known contemporary poets, their poet-fathers’ practical assistance and symbolic influence exacerbated the anxiety of reception for amateur contributors, and complicated each woman’s role as agent and subject of her own book. In the Wordsworth circle albums, scribal publication is perilously close to conventional publication, and contributors negotiate between fulfilling the woman owner’s wishes and articulating awareness of the revered older poets’ scepticism or downright hostility to feminized album culture. The poet-father’s presence turns albums into contested textual spaces where generational, gender, and power dynamics are played out in poetry.

Abstract:
According to Abraham Joshua Heschel, the prophet is inexorably drawn into the pathos of God—sensing something of God’s own desire to enter deeply into the inner consciousness of suffering human beings. In keeping faith with her own ‘dangerous memory’, Edith Stein witnesses to the prophetic effort to respond to the Word of God by forever seeking more imaginative ways of keeping alive the hope of a new creation. This raises the possibility that it is the figure of the prophet who provides Jews and Christians with a strand of interpretation with which to trace the continuities between ‘Old’ and ‘New’. As a creative force within the community of faith the prophet feels most deeply experiences of tragedy, loss, and crisis, responding with words of praise and lament, thanks and complaint, hope and repentance that are forever interacting with the wider world.

"As the producer of the two highest grossing lms of all time, Titanic and Avatar, Jon Landau keeps a relatively low prole. Landau has been director James Cameron’s hands-on producer ever since he was hired to produce Titanic (1997), for which they won the Best Picture Academy Award. The two rst met when Landau was an executive at Twentieth Century Fox in the early 1990s. Landau currently holds the COO title at Cameron’s production company, Lightstorm Entertainment. Landau grew up around the arts in New York, where his parents Ely and Edie Landau produced independent lms (Long Day’s Journey Into Night, 1962; The Man in the Glass Booth, 1975; Hopscotch, 1980). He followed into their profession, starting on small lms in the 1980s. The work eventually took Landau to Los Angeles, where his rst full producing job came on RKO/Paramount’s Campus Man (1987). Though that lm didn’t turn heads, Landau was able to move on to bigger studio projects. The visual effects experience Landau gathered on Disney’s Honey, I Shrunk the Kids (1989) brought him the opportunity to work as a co-producer on another Disney project, Warren Beatty’s comic adaptation Dick Tracy (1990). From there, Landau took an executive position as head of physical production at Fox, where he worked on lms including The Last of the Mohicans (1992), Power Rangers (1995), Mrs. Doubtre (1993), Aliens 3 (1992), and True Lies (1994). He followed his studio stint with Titanic and joined Cameron at Lightstorm, where Landau served as a producer on Steven Soderbergh’s sci- remake Solaris (2002) before embarking on the multi-year development journey for Avatar (2009). The 3D phenomenon broke new ground with performance-capture technology and techniques. Landau and Cameron were again nominated for the Best Picture Oscar, though The Hurt Locker (2008) took the prize in 2010. But Landau and team had plenty to celebrate when the lm went on to shatter all-time revenue records, including the one held by their own reigning champ, Titanic. More Avatar lms are in the works."

Full text
Abstract:
A combined system consisting of a forecast model to predict ice drift and a viewer tool for ice management, IceMS were developed for providing ice information during the Arctic Coring EXpedition (ACEX). The main task during the multi international expedition ACEX was to retrieve sediment cores from the Lomonosov Ridge in the central Arctic Ocean. Large ice floes or thick ice that drifts towards the drill ship threaten the operation by forcing the drill ship from its position. The gathered ice information was imported into IceMS and presented to the ice management team. Risk analysis for continued drilling operation was made, and instructions of where the Icebreakers Oden and Sovjetski Soyuz should break ice in the drilling area were carried out. The software IceMS contains tools to update the ice conditions, history lines of ships and buoys, and includes the possibility to import track lines showing the ice drift forecasts. The key concept is the combined visualization of map data and up to date imagery from satellite, airplane photos and ice charts, together with results from an ice drift forecast model. It is possible to move the images in IceMS map according to the observed ice drift recorded by the buoys placed on drifting ice floes. An overlay to mark and edit polygons, e.g. representing areas with certain ice classification, can be shown on top of the images. The edit overlay can be exported to file, which enables sharing of judgments and forecasts to other units. The model to predict ice drift is a state of the art ice drift model that is developed for describing rapid changes such as circular motion with a period of about twelve hours called inertial motion. The ice drift forecast was based on weather forecast and measured ocean currents near the drill site. The combined system of IceMS and the forecast model is being further developed for supporting ice management teams on offshore platforms and other constructions in ice infested areas. Results from Ice Management will be presented, showing examples of how IceMS presented ice information and validation of the ice drift model during the Arctic Coring EXpedition (ACEX). New tools in IceMS will also be presented.

Abstract:
The NASCAR Truck Aerodynamic Improvement team is tasked with providing aerodynamic analysis and improvement to Ford Performance and their factory supported team Brad Keselowski Racing for their Ford F-150 race trucks. A Ford F-150 race truck is a “stock” truck that has some modifications for racing speed and safety. Ford Performance, reached out to an MSOE student and asked if a Senior Design team and project could be assembled to provide them with some aerodynamic analysis and improvements that would not require them to build and test using a trial-and-error type method resulting in expensive, and real, testing. The purpose of this project was to conduct a computational fluid dynamic analysis on the truck and make design changes to the truck that will provide more down force on the front two tires. The areas of the truck that were studied included the side panels, deck lid, rear quarter panels, and frontal geometry. There were also constraints put in place by the NASCAR rulebook on the vehicle specifications. These rules limit the design changes that were made to the truck. The model was originally sent as a laser scanned STL file. This file needed to be heavily edited in order to be imported into the CFD program. The programs used to edit this file include Geomagic, Autodesk Fusion 360, and SolidWorks. Through using these programs, the laser scan file was modified to a usable format. Upon conclusion of the CFD simulations using ANSYS Fluent, it was found that the truck with no geometry changes displayed a drag coefficient of 0.489 and a lift coefficient of −0.815. These results were found after 10,000 iterations of testing. The standard deviation in the drag and lift coefficients were 0.00743 and 0.01660 respectively. All statistical calculations along with the averaged solutions were calculated using the data after the 2,500th iteration. This is because the nature of the CFD solutions tend to fluctuate greatly at first and then slowly converge with more iterations. After the 2,500th iteration, a relatively steady state in the solutions is met where the residuals are converging to a single value or the fluctuation in the solutions is repetitive. The following design changes were made in attempt to increase the down force on the truck. A rib was added to the side panel in order to increase the downforce on the truck. The side panel was also modified with a cut. The contour on the rear deck lid was smoothed in order to decrease drag on the truck. Slots were cut out of the shell of the truck behind the rear wheels on both sides of the truck. These slots were angled in an attempt to create down force on the rear wheels. The front splitter was lowered closer to the ground in attempt to increase air velocity moving under the truck. This higher velocity air would create a lower pressure region under the car which would increase down force. All of these modifications were applied to the initial truck body and tested using the same setup as the baseline. The most successful design change was the rear deck lid modification which resulted in a drag coefficient of 0.472 and a lift coefficient of −0.816. This is a 3.48% decrease in the drag coefficient and a 0.12% decrease in the lift coefficient (or 0.12% increase in downforce). The results of this project were purely simulation based; any real modifications and field testing made will be performed by Brad Keselowski Racing and Ford Performance.
