Next generation keyboards: The importance of cognitive compatibility

The computer keyboard of today is essentially the same as it has been for many years. Few advances have been made in keyboard design even though computer systems in general have made remarkable progress in improvements. This paper discusses the future of keyboards, their competition and compatibility with voice input systems, and possible special-application intelligent keyboards for controlling complex systems

Archaeological Monitoring Of The Histroric Gan\u27s Dam At Berry Creek Preserve For The Williamson County Parks Department, Williamson County Parks Department, Williamson County, Texas

Archaeological monitoring of repairs to the historic Gan’s Dam, previously recorded as one historic component of archaeological site (41WM17), was conducted October 2-12, 2013 at the Berry Springs Preserve in Williamson County, Texas. Previous storm damage caused the dam to fail and impounded pond waters pushed the surface portion of the historic dam downstream. Williamson County Parks Department contracted with a construction firm to make repairs to the dam. Consequently, AAG was contacted about the discovery of the subsurface old historic dam limestone blocks and this led to discussions with the Texas Historical Commission, Archeology Division, and with the U.S. Army Corps of Engineers (COE), Fort Worth District. Subsequently, a Texas Antiquities Permit (6674) for monitoring was obtained and all work was also conducted under the auspices of Section 106 of the National Historic Preservation Act. Construction resumed with AAG on-site to ensure that the remnant historic dam features were not disturbed. The remaining dam portions were encapsulated with cement to provide a strong retention dam and to provide for long-term preservation of the historic dame and any potential remaining cultural deposits. No artifacts or features were encountered during monitoring, therefore, only project records are curated at the Center for Archaeological Research at the University of Texas at San Antonio

Archaeological Survey Of The Nolan Creek Improvements For The City Of Belton, Bell County, Texas

In September 2013, American Archaeology Group LLC conducted an archaeological survey of three tracts of land along Nolan Creek totaling 8.68 acres for the City of Belton’s planned low water dam removal and replacement dam installed, development of a parking lot and trail for kayakers, and removal of a low water bridge crossing. These improvements are being funded by a Texas Parks & Wildlife Department grant. The investigation consisted of a pedestrian survey supported with mechanical trenching. No archaeological sites were identified during the survey. American Archaeology Group LLC recommends that construction within the project area should be allowed to proceed as planned without archaeological monitoring. No artifacts were recovered; therefore, no curation was arranged

An extension of the Kreiss stability theorem to families of matrices of unbounded order

AbstractThe Kreiss matrix theorem asserts three necessary and sufficient conditions for a family of matrices of fixed finite order to be L2-stable: a resolvent condition (R), a triangularization condition (S) and a Hermitian norm condition (H). We extend the Kreiss theorem to families of matrices of finite but unbounded order with the restriction that the degrees of the minimal polynomials of all matrices in the family are less than a fixed constant. For such matrix families, we show that (R) and (H) remain necessary and sufficient for L2-stability, while (S) must be replaced by a somewhat stronger “block triangularization” condition (S′). This extended Kreiss theorem permits a corresponding extension of the Buchanan stability theorem

Archaeological Survey Of The American Legion Park For The City Of Rosebud, Falls County, Texas

In June and July 2016, American Archaeology Group LLC conducted an archaeological survey of 23.21 acres of the existing American Legion Park in Rosebud, Texas. The investigation consisted of a pedestrian survey supported with mechanical trenching and shovel tests. The entire project right-of-way has been severely impacted by road construction, utilities installation, and previously used as a trash dump. The City of Rosebud plans to construct a hike and bike trail and place surface recreational facilities with minimal impacts. One historic archaeological site was identified and recorded as 41FA90. The site was recorded as 136.2 meters long and 58.8 meters in width, totaling 7,329 square meters in size. This site contains four historic features, of which two were relocated to the park area from other localities. The first historic feature was the old American Legion building that is actually a pier and beam wooden building known as “Old Hilltop School” that was originally constructed in 1921 and then moved into the American Legion Park in the 1950s. The building measured 75.5 feet by 38 feet and appears to AAG to be of Minimal Traditional style. In the March 8, 1963 Rosebud News, there is a small reference to a bandstand located behind the Legion Hall but no remains were located during the course of the current project. The American Legion Building has been referred to locally for many years as “The Caywood Center” in honor and memory of Mr. Brodie Lee Caywood. Mr. Caywood was born on March 7, 1894 in a small community named Minerva, which is located in Milam County. During World War I, Mr. Caywood enlisted as a Private in the U.S. Army, serving in Company M, 9th Infantry, 2nd Division. He was later killed on April 14, 1918 in France after fighting in Chateau-Thierry, Soissons, St. Mihiel, Champagne, and Argone. He was buried initially in France but later interred in the Woodlawn Cemetery in 1921 (Rosebud, Texas). Mr. Caywood never married and had no children. The American Legion honored Mr. Caywood in naming their new Brodie Lee Caywood Post 329 in Rosebud, within the American Legion Park (The Hilltop School Building), on April 28, 1922. The American Legion Post is no longer active. The City of Rosebud is contemplating what to do with this building, therefore, AAG believes that the building is not eligible for inclusion on the National Register of Historic Places (NRHP) nor worthy of designation as a State Antiquities Landmark (SAL). AAG recommends that the City of Rosebud consult with the Texas Historical Commission, Architecture Division, and the History Division prior to any restoration or other impacts to this building The second historic feature located on this site was a Bowstring pony truss bridge made by King Iron Bridge Company of Cleveland, Ohio from Carnegie steel which was placed across Salt Creek and used as a pedestrian bridge within the park, and also known as the Hope Memorial Bridge. During the project, very little was known as to when the bridge was built or when it was placed within the park. Archival research into these issues resulted in locating news articles in the Rosebud News indicating that the bridge was removed from its original location and moved to the park in 1963. The bridge apparently was taken from the FM 1671 at Wilson West to Bell County line and was 80 feet long and 12 feet wide in size (Rosebud News, March 29, 1963). The Rosebud News (July 5, 1963) reported that the “Legion Park has new attraction, a 90 foot [actually 80 foot] steel antique bridge built by King Iron Works in 1867. The span was taken from across Pond Creek last year and replaced with a new bridge, Falls Precinct No.3 Commissioner Felix Neimast gained the authority from either County Court members to place the bridge in the Legion Park, and the bridge was moved in Monday morning [July 1, 1963] from Lott where it had been repaired and painted. The same article also appeals to the public for donations to cover the costs of the wood flooring for the bridge. According to the July 12, 1963 edition of the Rosebud News, Sterling McClanhan, Falls County Engineer was mentioned using a winch truck to position the bridge over the creek in the park, using the County Road & Bridge Department. The historic Hope Memorial Iron Bridge appears to be eligible for inclusion on the NRHP and worthy of SAL designation to protect and preserve this very unique bridge. The City of Rosebud has plans to engage in restoration of this historic bridge and AAG recommends that prior to any restoration efforts that the Texas Historical Commission, Architecture Division and the History Division be consulted. The third historic feature located on the site was the historic swimming pool. The swimming pool was filled in with gravel and soil, and was more discernible while reviewing aerial photography on Google Earth. Archival research identified that a flurry of interest began in Rosebud in the Fall of 1962 when community leaders formed the Rosebud Recreation Club and launched plans to build a modern pool that would be 30 feet wide and 70 feet long, fully equipped and lighted swimming pool with filtration equipment (Rosebud News, September 14, 1962). The article further indicated that fourteen citizens wrote checks totaling $2,600 to build the swimming pool. The pool was named the “Parkview Pool” after seventh grader Jerry Mayer suggested the name during a naming contest (Rosebud News, May 17, 1963). The news articles suggest that the swimming pool was constructed sometime between September 1962 and May 1963. The pool has been filled in and is currently protected. The fourth historic feature was a cement foundation remnant that represents the remains of the swimming pool dressing room. Due to its fragmentary condition, and partial coverage by sod and grass, the estimated size was recorded as 10 x 25 feet in dimensions. AAG recommends that this area not be impacted and be preserved, perhaps with a historical marker at the location detailing the early Rosebud Recreation Club. The pool and concrete slab are not considered eligible for inclusion on the NRHP nor worthy of SAL designation. American Archaeology Group LLC recommends that construction be allowed to proceed as planned. It is always possible that buried cultural materials can be missed during any Phase I survey. Therefore, should any sites be found during the construction of this proposed water line, all work within the site area should cease until the situation can be evaluated by the Texas Historical Commission, in consultation with American Archaeology Group LLC, and the City of Rosebu

Archaeological Survey Of The 2017 Texas Capital Fund Infrastructure Improvements Project For The City Of Grapeland, Houston County, Texas

An archaeological survey totaling 21.9 acres in a parcel tract and 5,929 feet of proposed water and wastewater pipelines with a 50 foot right-of-way was completed for the proposed 2017 Texas Capital Fund Project for the City of Grapeland in Houston County, Texas (totaling 28.71 acres surveyed). American Archaeology Group LLC conducted the work under the auspices of Section 106 of the National Historic Preservation Act (NHPA) and Antiquities Permit Number 8154. This survey was conducted in September 2017. The project area is located in northern Houston County, Texas. The field investigation was performed using the pedestrian survey method supported by backhoe trenching to test for potential subsurface cultural deposits. No cultural resources were identified during the course of this survey, therefore, it is recommended that the proposed project be allowed to proceed as planned. Monitoring by an archaeologist is not considered necessary. No artifacts were recovered, and project survey records are houses at AAG
