Evaluation of Adaptive Computing Concepts for Classical ERP Systems and Enterprise Services (2006)

To ensure the operability and reliability of large scale Enterprise Resource Planning Systems (ERP), a peak-load oriented hardware sizing is often used. Better utilization can be achieved by employing an adaptive infrastructure based on smaller computational units in combination with an intelligent allocation management. The SAP University Competence Center (German SAP HCC) at the Technische Universit ¨at M¨unchen provides support for 55 ERP training systems. The evaluation of the historical load data revealed that many applications exhibit cyclical resource consumption. In this paper we show the extraction of load patterns and present self-organizing controlling concepts in the context of the SAP HCC.
ON THE ROLE OF BDI MODELING FOR INTEGRATED CONTROL AND COORDINATED BEHAVIOR IN AUTONOMOUS AGENTS (1995)

This paper describes an architecture for controlling and coordinating autonomous agents, building on previous work addressing reactive and deliberative control methods. The proposed multilayered hybrid architecture allows a rationally bounded, goal-directed agent to reason predictively about potential conflicts by constructing knowledge level models that explain other agents' observed behaviors and hypothesize their beliefs, desires, and intentions; at the same time, it enables the agent to operate autonomously, to react promptly to changes in its real-time environment, and to coordinate its actions effectively with other agents. A principal aim of this research is to understand the role dzfferent functional capabilities play in constraining an agent5 behavior under varying environmental conditions. To this end, an experimental test bed has been constructed comprising a simulated multi-agent world in which a variety of agent configurations and behaviors have been investigated. A number of experimentalfindings are reported.
CLOSING THE FLOODGATES (1990)

The White Rock Creek basin in Dallas and Collin Counties, is one of Texas’ most crucial resources. While large tracts of undeveloped land in Collin County remain under agricultural or open space use, other land is quickly being converted for residential and commercial projects. Within the basin runs the White Rock Creek, a major tributary of the Trinity River, which drains 136 sq mi. A flood plain management study of the creek--a joint effect between the cities of Plano and Dallas--was commissioned and included 60 mi of White Rock Creek and 33 tributaries in Dallas and Plano. Ultimately, a $7.8 million flood plain management plan was approved by the Dallas City Council in June 1988, and an $18.3 million plan was approved by the Plano in April 1989. Perhaps more significant, the Texas study featured several innovative flood plain management techniques, including a global positioning system; 3-D digital mapping and topography; a Geographic Information System with remote sensing; satellite surveying; and CADD maps. During the White Rock Creek study, these technologies showed potential for reducing manpower needs and improving accuracy for future flood plain management studies.
Facile Synthetic Route for Thickness and Composition Tunable Hollow Metal Oxide Spheres from Silica‐Templated Coordination Polymers (2011)

Monodisperse hollow metal oxides are generated from silica@coordination polymer core/shell precursors through a calcination process to transform coordination polymers into metal oxides, followed by an etching process to remove silica cores. The layer thicknesses of the hollow structures are effectively controlled by adjusting the shell thicknesses of the coordination polymers within the silica@coordination polymer core/shell precursors.

Spontaneous and augmented growth of axons in the primate spinal cord: Effects of local injury and nerve growth factor‐secreting cell grafts (2002)

Little is known about molecular and cellular responses to spinal cord injury in primates. In this study, the normal milieu of the primate spinal cord was disturbed by multiple needle penetrations and cell injections in the mid-thoracic spinal cord; subsequent effects on local axons and expression of extracellular matrix (ECM) molecules were examined, together with effects of cellular delivery of nerve growth factor (NGF) to the injured region. Four adult rhesus monkeys each received injections of two grafts of autologous fibroblasts genetically modified to secrete human NGF, and, in control injection sites, two separate grafts of autologous fibroblasts transduced to express the reporter gene, beta-galactosidase. Three months later, Schwann cells extensively infiltrated the region of localized injury and penetrated both NGF and control fibroblast grafts. Marked upregulation of several ECM molecules occurred, including chondroitin and heparan sulfate proteoglycans and type IV collagen, in or adjacent to all injection sites. Schwann cells were an apparent source of some ECM expression. Spinal cord sensory axons and putative coerulospinal axons extended into both graft types, but they penetrated NGF grafts to a significantly greater extent. Many of these axons expressed the cell adhesion molecule L1. Thus, extensive cellular and molecular changes occur at sites of localized primate spinal cord injury and grafting, attributable in part to migrating Schwann cells, and are accompanied by spontaneous axonal plasticity. These molecular and cellular events closely resemble those observed in the rodent spinal cord after injury. Furthermore, as in rodent studies, cellular delivery of a trophic factor significantly augments axonal plasticity in the primate spinal cord.
Photoinduced Ethylene Polymerization on the Cr<sup>VI</sup>/SiO<sub>2</sub> Phillips Catalyst (2018)

Herein we report on two photoinduced reactions occurring at the surface of the CrVI/SiO2 Phillips catalyst. The first is the photoreduction of CrVI/SiO2 in CO at room temperature, that leads to the reduction of a fraction of the CrVI sites to CrIV(═O) intermediates and then to CrII. With respect to the thermal reduction of CrVI/SiO2 in CO, the relative amount of highly uncoordinated CrII sites is larger, suggesting that the relaxation of the CrII sites at the silica surface strongly depends on the temperature at which they are formed. The second is the photoinduced ethylene polymerization on CrVI/SiO2 at room temperature that is reported here for the first time. We demonstrate that UV–vis light has the potential to trigger the reduction of chromates by ethylene and the successive ethylene polymerization. Diffuse reflectance (DR) UV–vis and FT-IR spectroscopies allowed us to identify the nature of the Cr sites involved in the polymerization (i.e., 6-fold coordinated CrII) and of the oxidized byproducts remaining in their coordination sphere, which are methylformate and ethylene oxide. While the former was previously observed during the thermally induced ethylene polymerization on CrVI/SiO2, the latter was never observed.
Application of delay tolerant networking (DTN) in Airborne Networks (2008)

As airborne networks (ANs) evolve and become increasingly net-centric, it is critical that apt consideration is given to properly extend Internet protocol (IP)-based networking services to the tactical assets. This is an effort to resolve current interoperability issues through the use of a standard protocol and provide IP connectivity between all airborne network platforms. However, large gaps exist between the current AN architecture and future envisioned net-centric capabilities. The dynamic nature of the AN topology, typically characterized by highly intermittent links and long link delays, limits the use and effectiveness of Internet-based standards and protocols. Developed separately, the delay tolerant network (DTN) architecture has been designed to address the needs of networks characterized by link intermittency, lack of end-to-end connectivity between end users, and high latency. While originally developed for deep space networking and inter-planetary communications, DTNs are highly applicable for sensor-based networks, terrestrial wireless networks, satellite networks, underwater acoustic networks as well as airborne networks. This paper addresses the specific challenges of establishing and maintaining reliable communications within an IP-based AN environment. In addition, this paper provides an overview of DTN, and details how this technology may be integrated into to the AN infrastructure in order to address the current issues affecting AN performance.
The source of fermentable carbohydrates influences the in vitro protein synthesis by colonic bacteria isolated from pigs (2007)

Two in vitro experiments were carried out to quantify the incorporation of nitrogen (N) by pig colonic bacteria during the fermentation of dietary fibre, including non-starch polysaccharides and resistant starch. In the first experiment, five purified carbohydrates were used: starch (S), cellulose (C), inulin (I), pectin (P) and xylan (X). In the second experiment, three pepsin-pancreatin hydrolysed ingredients were investigated: potato, sugar-beet pulp and wheat bran. The substrates were incubated in an inoculum, prepared from fresh faeces of sows and a buffer solution providing 15N-labelled NH4Cl. Gas production was monitored. Bacterial N incorporation (BNI) was estimated by measuring the incorporation of 15N in the solid residue at half-time to asymptotic gas production (T/2). The remaining substrate was analysed for sugar content. Short-chain fatty acids (SCFA) were determined in the liquid phase. In the first experiment, the fermentation kinetics differed between the substrates. P, S and I showed higher rates of degradation (P < 0.001), while X and C showed a longer lag time and T/2. The sugar disappearance reached 0.91, 0.90, 0.81, 0.56 and 0.46, respectively, for P, I, S, C and X. Among them, S and I fixed more N per gram substrate (P < 0.05) than C, X and P (22.9 and 23.2 mg fixed N per gram fermented substrate v. 11.3, 12.3 and 9.8, respectively). Production of SCFA was the highest for the substrates with low N fixation: 562 and 565 mg/g fermented substrate for X and C v. 290 to 451 for P, I and S (P < 0.01). In the second experiment, potato and sugar-beet pulp fermented more rapidly than wheat bran (P < 0.001). Substrate disappearance at T/2 varied from 0.17 to 0.50. BNI were 18.3, 17.0 and 10.2 fixed N per gram fermented substrate, for sugar-beet pulp, potato and wheat bran, respectively, but were not statistically different. SCFA productions were the highest with wheat bran (913 mg/g fermented substrate) followed by sugar-beet pulp (641) and potato (556) (P < 0.05). The differences in N uptake by intestinal bacteria are linked to the partitioning of the substrate energy content between bacterial growth and SCFA production. This partitioning varies according to the rate of fermentation and the chemical composition of the substrate, as shown by the regression equation linking BNI to T/2 and SCFA (r2 = 0.91, P < 0.01) and the correlation between BNI and insoluble dietary fibre (r = -0.77, P < 0.05) when pectin was discarded from the database.
Proton radiography and proton computed tomography based on time-resolved dose measurements (2013)

We present a proof of principle study of proton radiography and proton computed tomography (pCT) based on time-resolved dose measurements. We used a prototype, two-dimensional, diode-array detector capable of fast dose rate measurements, to acquire proton radiographic images expressed directly in water equivalent path length (WEPL). The technique is based on the time dependence of the dose distribution delivered by a proton beam traversing a range modulator wheel in passive scattering proton therapy systems. The dose rate produced in the medium by such a system is periodic and has a unique pattern in time at each point along the beam path and thus encodes the WEPL. By measuring the time dose pattern at the point of interest, the WEPL to this point can be decoded. If one measures the time–dose patterns at points on a plane behind the patient for a beam with sufficient energy to penetrate the patient, the obtained 2D distribution of the WEPL forms an image. The technique requires only a 2D dosimeter array and it uses only the clinical beam for a fraction of second with negligible dose to patient. We first evaluated the accuracy of the technique in determining the WEPL for static phantoms aiming at beam range verification of the brain fields of medulloblastoma patients. Accurate beam ranges for these fields can significantly reduce the dose to the cranial skin of the patient and thus the risk of permanent alopecia. Second, we investigated the potential features of the technique for real-time imaging of a moving phantom. Real-time tumor tracking by proton radiography could provide more accurate validations of tumor motion models due to the more sensitive dependence of proton beam on tissue density compared to x-rays. Our radiographic technique is rapid (~100 ms) and simultaneous over the whole field, it can image mobile tumors without the problem of interplay effect inherently challenging for methods based on pencil beams. Third, we present the reconstructed pCT images of a cylindrical phantom containing inserts of different materials. As for all conventional pCT systems, the method illustrated in this work produces tomographic images that are potentially more accurate than x-ray CT in providing maps of proton relative stopping power (RSP) in the patient without the need for converting x-ray Hounsfield units to proton RSP. All phantom tests produced reasonable results, given the currently limited spatial and time resolution of the prototype detector. The dose required to produce one radiographic image, with the current settings, is ~0.7 cGy. Finally, we discuss a series of techniques to improve the resolution and accuracy of radiographic and tomographic images for the future development of a full-scale detector.
Fieldwork Training In The Public Schools (1979)

Foxfire was the prototype classroom "cultural journalism" project. It had its beginnings in the ninth and tenth grade English classes of Eliot Wigginton, in the Rabun Gap community of Appalachian Georgia. Frustrated to the point of desperation by the curricular status quo, Wigginton and his students launched into a publication dedicated to the discovery, collection and preservation of the traditional culture and folklore of Southern Appalachia. Wigginton's students named their journal "Foxfire," after a tiny phosphorescent organism often seen in the shady coves of the deep mountains. Tape recorders, cameras and notebooks in hand, the students ranged far a field, collecting a wide variety of materials from the living repositories of the old "mountain culture." They transcribed and edited these materials, and in 1967 published the first issue of Foxfire—later sub-titled "hog dressing; log cabin building; mountain crafts and foods; planting by the signs; snake lore, hunting tales, faith healing, moonshining; and other affairs of plain living."

Multiple model predictive control of hemodynamic variables: an experimental study (1999)

A multiple model predictive controller is designed to regulate mean arterial pressure and cardiac output in critical care subjects using inotropic and vasoactive drugs. The algorithm uses a multiple model adaptive approach in a model predictive control framework to account for inter- and intra-patient variability and explicitly handle drug rate constraints. The controller is experimentally evaluated on canines that are pharmacologically altered to exhibit symptoms of hypertension and depressed cardiac output.
Sub boundary-layer vortex generators for the control of shock induced separation (2006)

Abstract The results of an investigation into the effects that sub-boundary layer vortex generators (SBVGs) have on reducing normal shock-induced turbulent boundary-layer separation are presented. The freestream Mach number and Reynolds number were M = 1·45 and 15·9 × 10 6 /m, respectively. Total pressure profiles, static pressure distributions, surface total pressure distributions, oil flow visualisation and Schlieren photographs were used in the results analysis. The effects of SBVG height, lateral spacing and location upstream of the shock were investigated. A novel curved shape SBVG was also evaluated and comparisons against the conventional flat vane type were made. The results show that in all but two cases, separation was completely eliminated. As expected, the largest SBVGs with height, h = 55%δ, provided the greatest pressure recovery and maximum mixing. However, the shock pressure rise was highest for this case. The experiments showed that the mid height SBVG array with the largest spacing provided similar results to the SBVG array with the largest height. Reducing the distance to shock to 10δ upstream also showed some improvement over the SBVG position of 18δ upstream. It was suggested that total elimination of the separated region may not be required to achieve a balance of improved static pressure recovery whilst minimising the pressure rise through the shock. The effect of curving the SBVGs provided an improved near wall mixing with an improved static and surface total pressure recovery downstream of the separation line. The optimum SBVG for the current flow conditions was found to be the curved vanes of h = 40%δ, with the largest spacing, located at 18δ upstream of the shock. Overall, it was apparent from the results that in comparison to larger vortex generators with a height comparable to δ, for SBVGs the parameters involved become more important in order to obtain the highest degree of mixing from a given SBVG configuration.
Formation Flight of Birds (1970)

Formation flight of birds improves aerodynamic efficiency. Theoretically, 25 birds could have a range increase of about 70 percent as compared with a lone bird, the advantage being more pronounced when there is a tail wind. A vee formation is required to equally distribute the drag saving, and, contrary to other statements, the lead bird does not necessarily have the most strenuous position. The angle of the predicted vee compares with that observed in nature; stability mechanisms are described which make it easy and natural for the bird to sense optimal formations.
The Green Canyon Event as Recorded by the Atlantis OBS Node Survey (2007)

Abstract Because of its location, the magnitude 5.2 Green Canyon earthquake of 10 February, 2006 has been of considerable interest to the oil industry. Unfortunately, because the nearby stations were all located to the North (onshore), its location and depth were only poorly constrained by the traditional worldwide seismic network. Fortunately, the Atlantis 3D survey happened to be ongoing at the time of the earthquake and recorded it on over 500 4C ocean-bottom nodes. The Atlantis array was closer to the event than any station on shore, and recorded the event from the South. These data thus provide an opportunity to dramatically refine our knowledge of the earthquake's location. We preserved 2.5 hours of data spanning the time of the earthquake and analyzed it for signals, both man-made and natural. Although there are a large number of overlapping signals in the data, they can be clearly separated by their distinct arrival times, temporal frequencies, and phase velocities across the 10km × 6km array. At frequencies of 5Hz and above repetitive air-gun signals from 4 ongoing seismic surveys dominate the data. These account for all the surveys shooting in the Northern Gulf of Mexico at the time. At frequencies of 1Hz and below there is a nearly continuous background noise coming primarily from the South and East that rumbles along for the entire 2.5 hours, with a phase velocity across the array of about 2000 m/s. This is most likely ocean wave-generated noise. At frequencies below 2Hz the earthquake signal dominates the data from 04:14:34 UT to about 04:20. It begins with several discrete arrivals from the NNW over a span of about 20 seconds, which are then followed by a drawn-out coda from the NW lasting over 8 minutes. At 04:22:13 a second event arrives from the SE, which is in turn followed by its own coda from the SSE, which lasts about 3 minutes. (It's not yet clear what this second event might be.) At about 04:27 a 3rd arrival, a weak, diffuse event from the ESE, fades in and lasts about 3 minutes. These data have been provided to earthquake experts and we expect to have a revised location for the event by the time of the OTC meeting in May. Preliminary indications are that the earthquake was well to the North of the originally published position. Making use of the Atlantis OBS-node array The geometry of the active nodes at the time of the earthquake is shown in Figure 1. We have a large, dense array (at least at low frequencies!) in this dataset, which allowed us to recycle a program called "Radar" for analyzing the signals in the data. "Radar" was originally written for examining surface-wave noise in land seismic data. It performs planewave stacks across the array and produces a graphical result showing the time, phase velocity, and azimuth of arriving energy. Figure 2 shows that "Radar" was able to correctly determine the azimuths of all the active air-gun surveys in the Northern Gulf of Mexico shooting at the time of the dataset.
