Aircraft traffic management on the airport surface using VHF data link for CNS (1995)

Aircraft traffic management on the airport surface will require the effective utilization of communications, navigation and surveillance (CNS). This paper describes an experiment which provides a glimpse of future automation. The experiment combines precision surface radar, high-accuracy differential GPS (DGPS) position determination, automatic dependent surveillance (ADS), and ground and airborne automation systems able to intercommunicate via a VHF data link. In particular, this paper describes the air/ground communications provided by the VHF Data Link. Two classes of messages are processed: continual and ad hoc. The former include DGPS corrections, ADS messages and target data. The latter include graphical taxi clearances and hold bar set-reset information. The work described in this paper is the result of a cooperative venture among NASA, Westinghouse-Norden Systems and ARINC.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
COVERING BOTTOM SEDIMENTS AS A LAKE RESTORATION TECHNIQUE<sup>1</sup> (1980)

ABSTRACT: Sediment covering to control macrophytes and sediment nutrient release is reviewed. It is concluded that fly ash application to control sediment phosphorus release presents more dangers to the lake than benefits and should not be used. Polyethylene sheeting has not had long term effectiveness due to macrophyte regrowth on its surface. PVC‐coated fiberglass screen is expensive but nontoxic and appears to give long term macrophyte control. Similar results may be obtained with spun‐bonded polypropylene. Sand, clay, and sheeting to retard nutrient release have received insufficient attention.

This paper discusses the performance of the new DS90C387/DS90CF388 LDI chipset.
Slack Stealing Job Admission Control (1998)

In this paper, we present Slack Stealing Job Admission Control (SSJAC)---a methodology for scheduling periodic firm-deadline tasks with variable resource requirements, subject to controllable Quality of Service (QoS) constraints. In a system that uses Rate Monotonic Scheduling, SSJAC augments the slack stealing algorithm of Thuel et al with an admission control policy to manage the variability in the resource requirements of the periodic tasks. This enables SSJAC to take advantage of the 31% of utilization that RMS cannot use, as well as any utilization unclaimed by jobs that are not admitted into the system. Using SSJAC, each task in the system is assigned a resource utilization threshold that guarantees the minimal acceptable QoS for that task (expressed as an upper bound on the rate of missed deadlines). Job admission control is used to ensure that (1) only those jobs that will complete by their deadlines are admitted, and (2) tasks do not interfere with each other, thus a job can o...
Aerosol classification using airborne High Spectral Resolution Lidar measurements – methodology and examples (2012)

Abstract. The NASA Langley Research Center (LaRC) airborne High Spectral Resolution Lidar (HSRL) on the NASA B200 aircraft has acquired extensive datasets of aerosol extinction (532 nm), aerosol optical depth (AOD) (532 nm), backscatter (532 and 1064 nm), and depolarization (532 and 1064 nm) profiles during 18 field missions that have been conducted over North America since 2006. The lidar measurements of aerosol intensive parameters (lidar ratio, depolarization, backscatter color ratio, and spectral depolarization ratio) are shown to vary with location and aerosol type. A methodology based on observations of known aerosol types is used to qualitatively classify the extensive set of HSRL aerosol measurements into eight separate types. Several examples are presented showing how the aerosol intensive parameters vary with aerosol type and how these aerosols are classified according to this new methodology. The HSRL-based classification reveals vertical variability of aerosol types during the NASA ARCTAS field experiment conducted over Alaska and northwest Canada during 2008. In two examples derived from flights conducted during ARCTAS, the HSRL classification of biomass burning smoke is shown to be consistent with aerosol types derived from coincident airborne in situ measurements of particle size and composition. The HSRL retrievals of AOD and inferences of aerosol types are used to apportion AOD to aerosol type; results of this analysis are shown for several experiments.

Backscattering cross section of a rigid biconic reflector (2000)

Plane wave incidence on a rigid biconic target is considered. A biconic reflector consists of two cones truncated by planes perpendicular to their axes and joined at their smaller flat faces. The cone angles are allowed to be variable, provided their sum is equal to 90 degrees. The backscattering cross section is expressed in terms of a surface integral of the geometrical acoustics field, which results from incident singly and doubly reflected rays. A saddle-point calculation gives a first-order high-frequency approximation in which the backscattering cross section is proportional to the incident wave number and a function of the angle of incidence, cone angles, and inner and outer radii of the truncated cones. This expression is algebraically complex but easy to implement numerically. Results are presented that exercise the parameters of the problem. An interesting result of the solution is that for fixed outer radii there is a nonzero optimum inner radius for backscattering strength. For broadside incidence on 45 degrees cones with equal outer radii, this optimum value is approximately equal to 11% of the outer radius.
Apple breeding: A study of Jonathan crosses (2017)

Two hundred seventy-three Jonathan seedlings produced by 11 crosses form the basis of the records in this bulletin.\nThese studies show clearly that the progenies produced by the different crosses of Jonathan differ or vary in many important characteristics. These variations are attributed to differences in the genetic constitution of the several varieties which were used in combination with Jonathan, and indicate the relative value of these varieties as parents when crossed with Jonathan.\nThe range of variation in the seedlings of these progenies is generally quite wide both as to tree and fruit. Differences in the horticultural characteristics such as occur in size, form, color, flavor, quality and season of the seedling fruits suggest that multiple factors are concerned, which produce the many variations observed.\nJonathan appears to carry as partially dominant factors for medium and below medium size of fruit, but it evidently carries factors also for large and for small size. Factors for roundish, conic, oblate and oblong fruit forms are present. Jonathan appears to be homozygous for red skin color but is heterozygous for pattern and carries factors for both fine and coarse grained flesh, for juiciness, for both acid and sweet flavor and for very good as well as for poor quality. The factors which control the season of the fruit are evidently complex. Jonathan appears to carry factors for season varying from late summer to late winter but probably carries as dominant the factors for mid-winter season.\nIt is of importance to observe that the color, size and flavor of Jonathan were recovered occasionally and that these characteristics were combined with the characteristics of the other parent variety.\nColorado Orange produced a higher percentage of fruits of good commercial size than did Salome, Anisim or Roman Stem when crossed with Jonathan. When crossed with Jonathan, Salome produced the highest percentage of fruit rating good and very good, followed in order by Colorado Orange, Anisim and Roman Stem. Late season appeared most often in the seedlings of Colorado Orange and Salome, while Anisim and Roman Stem produced no late season apples. The value of crossing two red apples is shown by the high percentage of good red seedling fruits produced by Anisim and Wealthy when crossed with Jonathan. It is interesting to note that Colorado Orange and Roman Stem produced a high percentage of seedling fruits which were deficient in good red color.
Haploid-diploid evolutionary algorithms: The Baldwin effect and recombination nature’s way (2017)

This paper uses the recent idea that the fundamental haploid-diploid lifecycle of eukaryotic organisms implements a rudimentary form of learning within evolution. A general approach for evolutionary computation is here derived that differs from all previous known work using diploid representations. The primary role of recombination is also changed from that previously considered in both natural and artificial evolution under the new view. Using well-known abstract tuneable models it is shown that varying fitness landscape ruggedness varies the benefit of the new approach.
Current initial therapy of stage III and IV ovarian cancer: challenges for managed care. (1999)

Patients with advanced ovarian cancer (International Federation of Gynecology and Obstetrics stage III or stage IV) have improved their long-term prognosis, but the majority will still die of their disease. The current standard therapy, which involves aggressive cytoreductive surgery (removal of all visible tumor) followed by platinum/paclitaxel chemotherapy, has increased 5-year survival rates considerably over the last three decades. The choice of treatment for patients with stage III or IV disease in the managed care setting must consider survival rates, patient quality of life, and cost-effectiveness. Two chemotherapy combinations, cisplatin/paclitaxel and carboplatin/paclitaxel, appear comparable in efficacy in advanced disease, but are currently being investigated in clinical trials to compare side effects, quality-of-life parameters, and cost-effectiveness. The results of these trials may determine which chemotherapy combination becomes the standard of care for first-line treatment. Managed care organizations and patients can also benefit from a multidisciplinary approach to cancer care that includes additional support, such as risk assessment programs, the use of specialists (gynecologic oncologists), and psychosocial counseling. As the search for more effective agents and other therapeutic modalities continues, the focus of future research may be to find specific biomarkers of ovarian cancer, which will help detect disease at its earliest stages.
Endoscopic palliative treatment of esophageal and cardial cancer: A new antireflux prosthesis a study of 40 cases (1984)

Forty patients with malignant cardioesophageal obstruction were treated by fiberoptic intubation. Their ages ranged from 38 to 84 years. Eight patients had bronchoesophageal fistula, 9 had tumor relapse after radiation therapy, and 5 had hiatal hernia. In 7 with severe or total stenosis, diathermic resection was used with no morbidity or mortality. Complications were hemorrhage, 2; regurgitation, 2; atelectasis, 1; tube migration, 1; and bronchoesophageal fistula, 1, for a total of 17.5%. The procedure mortality was 2.5%. Actual survival time after intubation was 37.5% at 12 months. It was demonstrated that a new antireflux prosthesis, designed for endoscopic insertion, diminished morbidity and avoids mortality due to regurgitation; we would therefore recommend to be used in patients not otherwise amenable to surgery or radiotherapy, with cancer of the cardia, lower esophagus or lesions beyond 24 mm from the incisors associated with hiatal hernia.
Robust downlink beamforming using positive semi-definite covariance constraints (2008)

We study the problem of multiuser downlink beamforming under the assumption that only an erroneous channel state information (CSI) is available at the transmitter. The optimization criterion is to minimize the total transmit power subject to the constraints that the user worst-case signal-to-interference-plus-noise ratios (SINRs) are above a pre-defined quality of service (QoS) threshold. In contrast to the earlier approaches to this problem, we take into account positive semi-definiteness of the mismatched channel covariance matrices. Two approaches to solve the resulting robust downlink beamforming problem are proposed using semidefinite programming (SDP). Simulation results validate the robustness of the proposed techniques.
Augmentation of Facial Soft-Tissue Defects with Alloderm Dermal Graft (1998)

Numerous materials, both autologous and nonautologous, have been used for augmentation of soft-tissue defects in the facial region. Each has its limitations. There is no ideal material for soft-tissue augmentation. Alloderm dermal graft (LifeCell Corporation, Woodlands, TX) combines the benefits of autografts and allografts. The authors report its use in 11 patients who have soft-tissue defects or scarring on the face. No serious complications such as rejection, mobilization, absorption, dislocation, or extrusion were encountered. The use of Alloderm in these patients minimized two problems: donor site morbidity and lack of adequate tissue for reconstruction. Alloderm is shown to be an excellent augmentation material for soft-tissue defects. The absence of a donor site defect, and adequate tissue for reconstruction are particularly helpful in the pediatric population.
Time Reference Microwave Landing System Multipath Control Techniques (1976)

The Time Reference Scanning Beam (TRSB) landing system is an air-derived data system which operates at microwave frequencies to provide guidance information proportional to an aircraft's lateral and vertical displacement from a selected flight profile. Angular position of an aircraft is measured in the aircraft by receiving ground generated fan beams which scan “to” and “fro” across the coverage sector in both azimuth and elevation. The airborne subsystem measures the elapsed time between a given “to”-“fro” scan. The time difference is controlled to be an indication of the aircraft's angular position. This indicated angle could be corrupted by multipath. Basic to the TRSB concept is the azimuth and elevation controlled antenna radiation patterns (both in the scan and non-scan dimensions) which, in conjunction with their high scan rates, control the multipath to an operationally acceptable level. Since the multipath is controlled primarily on the ground, there is no special impact on the cost of the airborne equipment because simple, conventional RF and signal processing techniques need only be implemented into the airborne receiver hardware.
Strategic uses of information technology in health care: a state-of-the-art survey. (1999)

The general perception that the use of information technology (IT) in health care is ten to fifteen years behind IT in other industrial sectors such as banking, manufacturing, and airline is rapidly changing. Health care providers, faced with an unprecedented era of competition and managed care, are now exploring the opportunities for using IT to improve the quality while simultaneously reducing the cost of health care. A revolution is taking place in the health care industry, with IT playing an increasingly important role in its delivery. In recent years, for example, the industry spent approximately $12 billion to $14 billion a year on IT. Further exponential growth is expected as the health care industry implements electronic medical records, upgrades hospital information systems, sets up intranets for sharing information among key stakeholders, and uses public networks, such as the Internet, for distributing health-related information and for providing remote diagnostics. Along with these drastic changes and the new approach to health care, the field of health/medical informatics and telematics has also experienced significant growth in the last few years. This article identifies and surveys the critical information technologies that are being adopted to provide strategic benefits to the various health care constituencies including hospitals and health maintenance organizations (HMOs).
Development of capacitance tomographic imaging systems for oil pipeline measurements (1995)

UMIST is one of the establishments where process tomography techniques were first developed. This paper introduces the development of capacitance tomographic imaging systems at UMIST for oil pipeline measurements. The principles of electrical capacitance tomography (ECT) are briefly presented and two ECT systems based on charge/discharge capacitance measuring circuits are described. These systems, a PC-based 8-electrode system and a Transputer-based 12-electrode system, have been used to visualise oil pipelines. Future developments of ECT technology are discussed, including a low-cost PC-based ECT system, a twin-plane ECT system which can measure the velocity profile of a pipeline flow, a multi-frequency ECT system using ac capacitance measuring circuits and an ECT system with a rotating parallel excitation field.
Enzyme Sensitive Synthetic Polymer Micelles Based on the Azobenzene Motif (2013)

In this study, we investigate the potential of an artificial structural motif, azobenzene, in the preparation of enzyme sensitive polymeric nanostructures. For this purpose, an azobenzene linkage is established at the copolymer junction of an amphiphilic diblock copolymer. This polymer assembles into a micellar structure in water. Treatment with the enzyme azoreductase, in the presence of coenzyme NADPH, results in the cleavage of the azo-based copolymer junction and disruption of the micellar assembly. These results suggest that azobenezene is a useful non-natural structural motif for the preparation of enzyme responsive polymer nanoparticles. Due to the presence of azoreductase in the human intestine, such nanomaterials are anticipated to find applicability in the arena of colon-specific delivery systems.
Sensuality and Consciousness VI: A Preconquest Sojourn: The Study of Child Behavior and Human, Development in Cultural Isolates (1998)

I am often asked how one finds isolated people whose whereabouts or existence is unsure. There is even greater curiosity about how one can join such people in the absence of common customs or spoken language. Moreso about how one makes sense of what one sees under such circumstances. After several years of contact with variously acculturated groups of settled and semi‐settled sea nomads in the Sea of Andaman Moken, Moklen, and Urak Lawoi (and its Lonta subgroup) two out‐of‐the‐blue opportunities unexpectedly occurred to travel with fully nomadic pagan ones, a type no longer thought to exist. The first trip was short, but it prepared me for the long next one. The first was a band of unknown origin, the second an aboriginal Moken‐related group off southern Burma.
Estradiol is associated with mortality in critically ill trauma and surgical patients (2008)

We conclude that serum estradiol correlates with mortality in critically ill and injured surgical patients and discuss potential mechanisms for this observation.
Modeling and Control of the Paper Machine Drying Section (2006)

The topic of this thesis is modeling and control of the last part of the paper machine - the drying section. Paper is dried by letting it pass through a series of steam heated cylinders and the evaporation is thus powered by the latent heat of vaporization of the steam. The moisture in the paper is controlled by adjusting the set point of the steam pressure controllers. There exist several commercial incentives to focus on the performance of the moisture control. The time to perform a grade change is often limited by the moisture and shorter grade change time is directly correlated to economic profit. Studies have shown that the drying section uses 2/3 of the total energy requirement in paper making. Reduced variations in moisture gives opportunity for target shifts (changed set point) which reduces the amount of raw material and steam requirement. It also creates opportunity for increased production rate. The thesis is divided in two parts. The first part deals with the control of the steam pressure inside the cylinders. Both a black-box model and a physical model are given for the steam pressure process. A tuning rule for both PI and PID control is derived and various other controller structures are investigated. Many of the results are verified by experiments on paper machines at different paper mills. The second part of the thesis treats the moisture controller. The physical model from the first part is expanded with a model for the paper. This gives a complete simulation model for the drying section that is implemented in the object-oriented modeling language Modelica. Two new approaches to control the moisture by feedback are evaluated. The first utilizes the air around the paper in combination with the drying cylinders to improve the controller performance. The second uses only the last part of the drying section to control the moisture, while the first part is put at an appropriate level. Finally, feedforward of a surface temperature signal is examined.
