Interface Usability

These are exciting days for cartography, as emerging technologies have greatly expanded the possibilities of online, interactive maps. These developments, however, now require cartographers to think about issues that only a few years ago fell solely in the domains of human-computer interaction (HCI) and web design. Further, given how fast these changes have occurred, there are few tried-and-true guidelines for building digital maps. This paper reports on the design, development, and evaluation of the University of Wisconsin-Madison Lakeshore Nature Preserve Interactive Map (www.lakeshorepreserve.wisc.edu) and outlines many of the insights gleaned from this process. The purpose of this article is to strengthen the important bridge between cartography and usability evaluation (i.e., how we study the way in which users interact with their maps and how we measure the success of those interactions) so that the efforts of a team of developers and stakeholders can be coordinated in a way that ensures the map works equally well for all potential end users. We outline the relative merits of two broad categories of evaluation techniques, arguing that there is no single, correct evaluation technique appropriate for all evaluation scenarios, and then detail the specific strategy adopted for evaluation of the Lakeshore Nature Preserve Interactive Map. We conclude by offering four design guidelines for online, interactive maps revealed during the evaluation of the Lakeshore Nature Preserve Interactive Map: two positive strategies we recommend for consideration when designing map interfaces (inclusion of cascading interface complexity and provision of map browsing flexibility) and two pitfalls we caution to avoid (minimalist design of interface widgets and employment of a lorem ipsum map during development).

The University of Wisconsin (UW) Madison's five main natural history collections (Anthropology, Entomology, Geology, Herbarium, and Zoology) have joined together to begin digitizing our collections and disseminating information online via an integrated web portal. This two-year project, currently beginning its second year, is the result of a UW2020 grant, "Development of the Wisconsin Integrated Biodiversity, Human, and Environmental Specimen Portal." The first objective of the grant is to initiate, or assist with current, digitizing efforts within each collection. This step includes photographing, inventorying, and/or cataloging specimens and either entering new records or updating existing records in collection-specific databases. The remaining objective is to design and implement a web presence (in the planned format of a web portal) to allow the ability to search a limited number of fields from all of the collections' databases. This step, currently still in the planning stages, involved hiring a temporary employee to liaise between all of the collections, perform the web design, and write the background scripts to pull needed data from each collection's database program. This presentation will outline the grant goals and progress to date by each collection, although the primary focus will be on the successes and limitations in the Anthropology collection.

Interactive Cartography

Cartographic interactivity is now most often understood as an addition to cartographic representations for end users of electronic maps. The article substantiates the need to extend this understanding. This extension will help in creation of the modern atlas systems, which are increasingly being developed as integrated or consisting of several systems. Along with end users, expert-cartographers (developers) and analysts also become users of atlas systems and their interactive maps. Users with relevant knowledge are combined into epistemologically ordered echelons – the higher the echelon, the more knowledge about interactivity the user should possess. Therefore, atlas interactive cartography should now be considered for many simultaneously operating systems and for many users. Examples of new operations of cartographic interactivity for new echelons of users are given: for expert-cartographers this is a dynamic change (i. e. during the operation of the system) of the cartographic method of modeling actuality, and for analysts, the model itself. A review of software solutions that are used to implement extended cartographic interactivity when creating a new generation of atlas systems has been completed. To prove the results, the methods of new relational cartography are used. In particular, the method of conceptual frameworks of atlas systems is used, which allows combining the methods of classical cartography and the methods of relational cartography into the system method of future system cartography. As examples of the paradigms of classical cartography, the communicative paradigm and growth perspective of R. Roth from the University of Wisconsin-Madison are chosen.

Abstract This study investigates performance-based design optimization for a Kaplan hydro turbine at a maximum water head of 2.6 m (8.5 ft), a micro-sized horizontal Kaplan turbine with 7.6 cm (3.0 in) diameter that has fixed blades featured to attain the optimum performance for such type and size of hydro turbines. The optimization process includes solving design problems and enhance design development by applying a multi-disciplinary design optimization (MDO) technique. Varying the geometrical parameters of the turbine, i.e., dimensions, number of blades, blade wrap angles, and different rotational speeds (500–3000 rpm), are the relevant proposed disciplines of this study. Two multi-simulation matrices were solved by using the high-performance computing (HPC) cluster of the University of Wisconsin-Milwaukee. The first matrix includes different number of the blades (3, 4, 5, 6, and 7 blades) over six different rotational speeds (500, 1000, 1500, 2000, 2500, and 3000 rpm), while the second matrix includes 121 possible combinations of blade wrap angles starting at 60–60 deg (hub-shroud) angle to 110–110 deg angle with 5 deg increment alternated at both sides, the hub and the shroud.

Varying the geometrical parameters of the turbine, i.e., dimensions, number of blades, blade wrap angles, and different rotational speeds (500–3000 RPM) are the relevant proposed disciplines of this study. An in-house code is used for optimizing the geometrical parameters of the turbine. A numerical solution that utilizes computational fluid dynamics (CFD) for a 3D, turbulent, transient unsteady and swirl flow is developed using STAR-CCM+ software in conjunction with an experimental setup of a lab-sized closed-loop water system for validation. The performance of the turbine is predicted by evaluating the power output (in watts), mesh independency analysis is also presented for CFD results validation. Two multi-simulation matrices were solved by using the high-performance computing (HPC) cluster of the University of Wisconsin-Milwaukee. First matrix includes different number of the blades (3, 4, 5, 6, and 7 blades) over six different rotational speeds (500, 1000, 1500, 2000, 2500, and 3000), while the second matrix includes 121 possible combinations of blade wrap angles starting at 60°-60° (hub-shroud) angle to 110°-110° angle with 5° increment alternated at both sides, the hub and the shroud.

Map Search

Purpose – Search engines and web applications have evolved to be more tailored toward individual user’s needs, including the individual’s personal preferences and geographic location. By integrating the free Google Maps Application Program Interface with locally stored metadata, the author created an interactive map search for users to locate, and navigate to, destinations on the University of New Mexico (UNM) campus. The purpose of this paper is to identify the characteristics of UNM map search queries, the options and prioritization of the metadata augmentation, and the usefulness and possible improvement of the interface. Design/methodology/approach – Queries, search date/time, and the number of results found were logged and examined. Queries’ search frequency and characteristics were analyzed and categorized. Findings – From November 1, 2012 to September 15, 2013, the author had a total 14,097 visits to the SearchUNM Maps page (http://search.unm.edu/maps/). There were total 5,868 searches (41 percent of all the page visits), and out of all the search instances, 2,297 of them (39 percent) did not retrieve any results. By analyzing the failed queries, the author was able to develop a strategy to increase successful searches. Originality/value – Many academic institutions have implemented interactive map searches for users to find locations and navigate on campus. However, to date there is no related research on how users conduct their searches in such a scope. Based on the query analysis, this paper identifies user’s search behavior and discusses the strategies of improving searches results of campus interactive maps.

The High Voltage Electron Microscope Laboratory at the University of Wisconsin has been in operation a little over one year. I would like to give a progress report about our experience with this new technique. The achievement of good resolution with thick specimens has been mainly exploited so far. A cold stage which will allow us to look at frozen specimens and a hydration stage are now being installed in our microscope. This will soon make it possible to study undehydrated specimens, a particularly exciting application of the high voltage microscope.Some of the problems studied at the Madison facility are: Structure of kinetoplast and flagella in trypanosomes (J. Paulin, U. of Georgia); growth cones of nerve fibers (R. Hannah, U. of Georgia Medical School); spiny dendrites in cerebellum of mouse (Scott and Guillery, Anatomy, U. of Wis.); spindle of baker's yeast (Joan Peterson, Madison) spindle of Haemanthus (A. Bajer, U. of Oregon, Eugene) chromosome structure (Hans Ris, U. of Wisconsin, Madison). Dr. Paulin and Dr. Hanna are reporting their work separately at this meeting and I shall therefore not discuss it here.

Ustilago hordei and Ustilago violacea are yeast-like basidiomycete pathogens ofHordeum vulgare and Silene alba respectively. The mating type system in both species of Ustilago is bipolar, with alleles, A,a, (U.hordei) and a1, a2 (U.violacea) at a single locus. Haploid sporidia maintain the asexual phase by budding, while the sexual phase is initiated by conjugation tube formation between the mating types during budding and conjugation.For observation of budding, sporidia were prepared by culturing the four types on YEG (yeast extract glucose) broth for 24 hours. After centrifugation at 5000g cells were either left unmated or mated in a1/a2,A/a combinations. The sporidia were then mixed 1:1 with 4% agar and the resulting 1mm cubes fixed in 8% gluteraldehyde and post fixed in osmium tetroxide. After dehydration and embedding cubes were thin sectioned with a LKB ultratome and photographed in a Zeiss 9s transmission electron microscope or in an AE1 electron microscope of MK11 1MEV at the High Voltage Electron Microscopy Center of the University of Wisconsin-Madison.
