Developing Water Areas for Outdoor Recreation
No full textWater and recreation go together. Iowa has many potential water recreation areas, including man-made or constructed lakes. The author gives a broad outline for those concerned with recreational development, indicating the many considerations for a sound project down to estimating costs for specific projects.</p

At Ames Library: A Ghazal
No full textTo commemorate the 10th Anniversary of The Ames Library, the library held a poetry contest in which students were asked to submit poems that focused on the library, in an original and creative way. The winning poem, by Madeline Tyner, was read by the author at the 10th Anniversary Reception held on April 18, 2012 in the Bates-Merwin Reading Room, Ames Library
Festival Playhouse 1987 Season program
No full text8 p.Program for the 1987 season of Festival Playhouse. Features four plays: Charley's Aunt by Brandon Thomas and directed by D. Terry Williams (July 9-12, 16-18), Master Harold and the Boys by Athol Fugard and directed by Ed Menta (July 23-25, 30-31, August 1, 6-8), Harvey by Mary Chase and directed by David Grapes (July 30-31, August 1-2, 6-8), and Beggar Moon by Conrad Hilberry and with music by Merwin Lewis, directed by Nelda K. Balch (August 20-23, 27-29).This was the world premiere of Beggar Moon; author Conrad Hilberry was a Professor of English at the time, and his poems were set to song by Kalamazoo College alumnus Merwin Lewis. The play was based on the Brothers Grimm fairy tale "King Thrushbeard.
Lincoln and May
No full text The author presents the life of Abraham Lincoln as an example of Rollo May’s philosophical conceptualization of destiny. May used the term destiny to refer to the talents and limitations fated to us. Moreover, he emphasized the responsibility to act with freedom to shape destiny. In overcoming hardship and achieving greatness, Lincoln challenged his destiny. Additionally, the author proposes that Lincoln’s depression was precipitated by a moral crisis, relating to his personal responsibility in developing “self.” Lincoln’s observations about the causes of his depression are understood in terms of encounters with destiny. Not in spite of but because of his misery, he defined and fulfilled his destiny, thereby creating a life of meaning and significance. Thus, Lincoln is presented as a model for May’s ideas about challenging life’s limitations, developing talents, grappling with life’s pain, and creating meaning. </jats:p
A computerized method for the hydrologic design of culverts.

In Iowa, average annual construction costs on theinterstate, primary, and federal-aid secondary systems are about6,000,000 are spent on culvert construction annually. For each one percentreduction in overall culvert costs, annual construction costs wouldbe reduced by $60,000
Theoretical and experimental investigation of additive drag
No full textThe significance of additive drag is discussed and equations for determining its approximate value are derived for annular and open-nose inlets. Charts are presented giving values of additive drag coefficient over a range of free-stream Mach numbers for open and for annular-nose inlets with conical flow at the inlet. The effects on additive drag of variable inlet-total-pressure recovery and static pressures on the centerbody are investigated and an analytical method of predicting the variation of pressure on the centerbody with mass-flow ratio is given. Experimental additive-drag values are presented for a series of 20 degree and 25 degree cone half-angle inlets and one open-nose inlet operating at free-stream Mach numbers of 1.8 and 1.6. A comparison with the theoretical values of additive drag shows excellent agreement for the open-nose inlet and moderately good agreement for the annular inlets. (author
Towards automatic semantic labelling of 3D city models
No full textThe lack of semantic information in many 3D city models is a considerable limiting factor in their use, as a lot of applications rely on semantics. Such information is not always available, since it is not collected at all times, it might be lost due to data transformation, or its lack may be caused by non-interoperability in data integration from other sources. This research is a first step in creating an automatic workflow that semantically labels plain 3D city model represented by a soup of polygons, with semantic and thematic information, as defined in the CityGML standard. The first step involves the reconstruction of the topology, which is used in a region growing algorithm that clusters upward facing adjacent triangles. Heuristic rules, embedded in a decision tree, are used to compute a likeliness score for these regions that either represent the ground (terrain) or a RoofSurface. Regions with a high likeliness score, to one of the two classes, are used to create a decision space, which is used in a support vector machine (SVM). Next, topological relations are utilised to select seeds that function as a start in a region growing algorithm, to create regions of triangles of other semantic classes. The topological relationships of the regions are used in the aggregation of the thematic building features. Finally, the level of detail is detected to generate the correct output in CityGML. The results show an accuracy between 85 % and 99 % in the automatic semantic labelling on four different test datasets. The paper is concluded by indicating problems and difficulties implying the next steps in the research.Urban Data Scienc
