Using Condition Based Maintenance to Improve the Profitability of Performance Based Logistic Contracts (2009)

This paper outlines a scheduling algorithm which leverages Condition-Based Maintenance (CBM) data to determine when maintenance should be performed. The objective of the scheduler is to reduce the cost associated with Performance-Based Logistics contracts, which ultimately improves the profit margins of Product Support Providers.An example consisting of 50 aircraft for which regular recurring maintenance and CBM actions are required is analyzed as a representative problem both in term of complexity and scale. The results indicate that significant cost savings can be achieved by utilizing a CBM scheduling algorithm. In addition, to the maintenance cost savings, the CBM scheduling algorithm is also able to identify potential resource limitations within the maintenance organization.
Mining Heterogeneous ADS-B Data Sets for Probabilistic Models of Pilot Behavior (2010)

The University of North Dakota is developing airspace within the state where Unmanned Aircraft Systems (UASs) can be flown without an onboard sense and avoid system or Temporary Flight Restrictions (TFRs). With funding from the U.S. Air Force, a mobile ground-based radar system capable of detecting aircraft operating in Class E airspace and the software to display such information to UAS operators is being developed. The current system uses an Automatic Dependent Surveillance - Broadcast (ADS-B) transceiver to detect any ADS-B-equipped aircraft within the vicinity, and a Ground Control Station (GCS) to detect and control the UAS. Once one or more ground-based radars are integrated into the system, it will also be capable of detecting non-cooperative aircraft (i.e. aircraft that aren't equipped with ADS-B transceivers) operating within the vicinity. The current system uses a portable, high-availability architecture. Since the system is intended to detect potential airspace conflicts from the ground, greater computational power is available to it than to onboard sense and avoid systems. The probability of a midair collision is dependent on the proximity of aircraft to each other, the performance characteristics of the aircraft, and the probabilities of pilots performing basic maneuvers with the aircraft. In this paper the authors present the results of data mining an ADS-B data set from 11 days in early 2010. Probabilistic models of pilot behavior were automatically extracted from the data using a genetic algorithm for cluster analysis.

New specific synonymy in Scolytidae is proposed for: Chortastus agnatus Eggers ( = Afromicracis baguenai Schedl), Pelicerus (now Dendrographus) pygmaeus Eggers ( = Protopityophthorus durus Schedl). The status of Pseudomicracus Eggers is discussed. The following new genera are proposed in Scolytidae: Phloeographus (type-species: Phloeographus mamibiae Wood), Phloeocurus (type-species: Hylocurus africanus Schedl), Saurotocis (type-species: Micracidendron tomicoides Schedl), and Peridryocoetes (type-species: Ozodendron nitens Schedl). Pseudothysanoes spinatulus, new name, is proposed to replace P. spinatus Wood, 1956.
An Architecture to Support an Open Distributed Hypermedia System (1995)

This article outlines significant advances on Hill&apos;s contribution through the provision of a heterogeneous and distributed framework, above which a new open hypermedia system has been layered. The new system retains the Microcosm philosophy but offers greater scaleability, improved process management and more efficient communication. We anticipate that users will benefit from the superior model for open hypermedia that this widely distributed version of Microcosm provides.
Controlling Phase Behavior in Nonionic Surfactant System (1996)

Phase behavior of polyoxyethylene-Type nonionic surfactant is highly influenced by temperature. At the particular temperature called HLB temperature, nonionic surfactant forms a three-phase region containing middle-phase microemulsion or surfactant phase. Maximum solubilization, ultralow interfacial tension, and phase inversion in emulsions take place at the HLB temperature. The HLB temperature in a multi-surfactant system is explained by analyzing the three-phase behavior. HLB number of commercial surfactant can be calculated from the HLB temperature. The effect of mixing nonionic surfactant on the maximum solubilization power is discussed. Finally, the unique phase behavior of biocompatible sucrose alkanoate is also described.
Studies on orally active cephalosporin esters. V. A prodrug approach for oral delivery of 3-thiazoliomethyl cephalosporin. (1990)

Oral delivery of 3-thiazoliomethyl cephalosporin 1 was attempted through a prodrug approach by applying thiamine chemistry. The 3-thiazoliomethyl group was modified to a ring-opened structure with no ionic charge, and the 4-carboxyl group was converted to pivaloyloxymethyl ester. Lipophilicity of the resulting derivatives (8-10) was suitable for passive absorption from the intestinal tract, and chemical stability in phosphate buffer solution (pH 6.86) was moderate. When administered orally to mice, these derivatives were mainly transformed to a novel 3-spiro cephalosporin 11, and desired reconversion to the 3-thiazoliomethyl cephalosporin was minor. Isomerization to delta 2-cephalosporin 14 was also observed. These results showed that the derivatives (8-10) tested in this study did not serve as orally active prodrugs of 3-thiazoliomethyl cephalosporin 1.
Synergistic effects of ultraviolet radiation, thermal cycling and atomic oxygen on altered and coated Kapton surfaces (1992)

The photovoltaic (PV) power system for Space Station Freedom (SSF) uses solar array blankets which provide structural support for the solar cells and house the electrical interconnections. In the low Earth orbital (LEO) environment where SSF will be located, surfaces will be exposed to potentially damaging environmental conditions including solar ultraviolet (UV) radiation, thermal cycling, and atomic oxygen. It is necessary to use ground based tests to determine how these environmental conditions would affect the mass loss and optical properties of candidate SSF blanket materials. Silicone containing, silicone coated, and SiO(x) coated polyimide film materials were exposed to simulated LEO environmental conditions to determine there durability and whether the environmental conditions of UV, thermal cycling and oxygen atoms act synergistically on these materials. A candidate PV blanket material called AOR Kapton, a polysiloxane polyimide cast from a solution mixture, shows an improvement in durability to oxygen atoms erosion after exposure to UV radiation or thermal cycling combined with UV radiation. This may indicate that the environmental conditions react synergistically with this material, and the damage predicted by exposure to atomic oxygen alone is more severe than that which would occur in LEO where atomic oxygen, thermal cycling and UV radiation are present together.
Pyridoxalated Hemoglobin Polyoxyethylene Conjugate (Php) on the Endothelium-Dependent Relaxation in Rat Mesenteric Arterioles (1992)

Effects of exchange-transfusion with a modified hemoglobin (pyridoxalated hemoglobin polyoxyethylene conjugate; PHP) on diameter of rat mesenteric arterioles responding to various vasoactive substances were examined using the image-splitter television microscopy method. The mesentery of the anesthetized rat was spread over the stage of a microscope and the microvasculature was visualized by transillumination. Exchange-transfusion with a 6%PHP solution (30 ml/kg) was performed and effects of topical application of norepinephrine (NE) and acetylcholine(ACh) on diameter of mesenteric arterioles were examined. By exchange-transfusion with PHP, NE induced a dose-dependent decrease in diameter, while ACh induced a dose-dependent increase in diameter of the arterioles preconstricted by NE. There was no difference in vascular responsiveness to ACh and NE before and after exchange-transfusion with PHP solution. Results suggest that circulating PHP moiety does not exert any action on function of endothelial cell to release endothelium-derived relaxing factor (EDRF) in rat mesenteric microvasculature in situ.

Passive duplicate address detection in mobile ad hoc networks (2004)

Auto-configuration of nodes is an important issue in self-organizing mobile ad hoc networks (MANETs). Especially the property of unique addresses is critical for the main task of a data network: the delivery of packets to the intended destination. Stateless auto-configuration allows a node to construct an address on its own. Duplicate address detection (DAD), usually done by sending a query to the chosen address and waiting for a response, can be used to ensure the uniqueness of this address. The other approach, the distributed assignment of a priori unique address, can also be a bandwidth consuming task in a dynamic environment. In both cases, a merger of two configured networks is very difficult to detect and can lead to duplicate addresses. Thus, a continuous and bandwidth-efficient duplicate address detection mechanism would be eligible. In this paper, the feasibility of a new DAD approach is investigated: the detection of duplicate addresses in a passive way, only by monitoring routing protocol traffic. Based on classic link state routing, three concepts of passive duplicate address detection (PDAD) are proposed. Two link-state protocols currently in discussion in the IETF MANET working group, the fisheye state routing (FSR) protocol and the optimized link state routing (FSR) protocol and the optimized link state routing protocol (OLSR), are analyzed regarding these concepts. Finally, first simulation results are presented.
<title>Remote sensing for gas plume monitoring using state-of-the-art infrared hyperspectral imaging</title> (1999)

Under contract to the US Air Force and Navy, Pacific Advanced Technology has developed a very sensitive hyperspectral imaging infrared camera that can perform remote imaging spectro-radiometry. One of the most exciting applications for this technology is in the remote monitoring of gas plume emissions. Pacific Advanced Technology (PAT) currently has the technology available to detect and identify chemical species in gas plumes using a small light weight infrared camera the size of a camcorder. Using this technology as a remote sensor can give advanced warning of hazardous chemical vapors undetectable by the human eye as well as monitor the species concentrations in a gas plume from smoke stack and fugitive leaks. Some of the gas plumes that have been measured and species detected using an IMSS imaging spectrometer are refinery smoke stacks plumes with emission of CO<SUB>2</SUB>, CO, SO<SUB>2</SUB>, NO<SUB>x</SUB>. Low concentration vapor unseen by the human eye that has been imaged and measured is acetone vapor evaporating at room temperature. The PAT hyperspectral imaging sensor is called 'Image Multi-spectral Sensing or IMSS.' The IMSS instrument uses defractive optic technology and exploits the chromatic aberrations of such lenses. Using diffractive optics for both imaging and dispersion allows for a very low cost light weight robust imaging spectrometer. PAT has developed imaging spectrometers that span the spectral range from the visible, midwave infrared (3 to 5 microns) and longwave infrared (8 to 12 microns) with this technology. This paper will present the imaging spectral data that we have collected on various targets with our hyperspectral imaging instruments as will also describe the IMSS approach to imaging spectroscopy.
Generation and testing of clinical-grade exosomes for pancreatic cancer (2018)

Exosomes are extracellular vesicles produced by all cells with a remarkable ability to efficiently transfer genetic material, including exogenously loaded siRNA, to cancer cells. Here, we report on a bioreactor-based, large-scale production of clinical-grade exosomes employing good manufacturing practice (GMP) standards. A standard operating procedure was established to generate engineered exosomes with the ability to target oncogenic Kras (iExosomes). The clinical-grade GMP iExosomes were tested in multiple in vitro and in vivo studies to confirm suppression of oncogenic Kras and an increase in the survival of several mouse models with pancreatic cancer. We perform studies to determine the shelf life, biodistribution, toxicology profile, and efficacy in combination with chemotherapy to inform future clinical testing of GMP iExosomes. Collectively, this report illustrates the process and feasibility of generating clinical-grade exosomes for various therapies of human diseases.

Human nucleolus organizers on nonhomologous chromosomes can share the same ribosomal gene variants. (1981)

The distributions of three human ribosomal gene polymorphisms among individual chromosomes containing nucleolus organizers were analyzed by using mouse--human hybrid cells. Different nucleolus organizers can contain the same variant, suggesting the occurrence of genetic exchanges among ribosomal gene clusters on nonhomologous chromosomes. Such exchanges appear to occur less frequently in mice. This difference is discussed in terms of the nucleolar organization and chromosomal location of ribosomal gene clusters in humans and mice.
Novel fault-tolerant circuits for configurable mass memories (2002)

Innovative orthogonal shuffle circuits, error correction by weighted codes, associative iterative repair, configurable modular architecture, and hierarchical organization in highly structured implementation are proposed for monolithic mass memories. Tests on experimental 40-Mb and 10-Mb monolithic CMOS static memories demonstrated read and write data rate of 120 MHz, module access time of 25 ns, power dissipation of 880 mW, mean time between failures of>0.5 Mh, data retention time of 10 years, and radiation hardness of 1 Mrad. The experimental memory devices are manufacturable with low-cost VLSI processing technologies which are normally used for digital logic circuits only. This work signifies that circuit innovations make possible the enlargement of chip sizes to wafer sizes without compromises in manufacturability and performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Studies on vaccination against bacillary dysentery. 5. Studies in Erythrocebus patas. (1970)

In earlier studies in man it has been demonstrated that streptomycin-dependent shigellae, if given orally in 5 sufficiently large doses, confer a very high type-specific protection against bacillary dysentery.In the present study, 2 groups of Erythrocebus patas monkeys were immunized with live streptomycin-dependent Shigella flexneri 2a, and a third group was not vaccinated. One of the vaccinated groups was given streptomycin with each dose of the live vaccine. The animals that received streptomycin with the vaccine were shedding these organisms in their faeces for a significantly longer period than the animals that did not receive streptomycin. A week after the last dose of vaccine, the animals were challenged with virulent Sh. flexneri 2a organisms. All the control animals developed diarrhoea and excreted challenge organisms for an average of 9 days. None of the 9 immunized animals showed pathological changes nor symptoms of dysentery. On average, they excreted challenge organisms for only 2.3 days.Immunological tests confirmed the immunity of the vaccinated animals.This study shows that 3 doses of live oral streptomycin-dependent Shigella vaccine given together with streptomycin are at least as effective as immunization with 5 doses of the same vaccine without streptomycin. Oral application of streptomycin, therefore, seems to have had an enhancing effect on the immunizing property of live oral streptomycin-dependent enteric vaccines.
Practical dynamic software updating for C (2006)

Software updates typically require stopping and restarting an application, but many systems cannot afford to halt service, or would prefer not to. Dynamic software updating (DSU) addresses this difficulty by permitting programs to be updated while they run. DSU is appealing compared to other approaches for on-line upgrades because it is quite general and requires no redundant hardware. The challenge is in making DSU practical : it should be flexible, and yet safe, efficient, and easy to use.In this paper, we present Ginseng, a DSU implementation for C that aims to meet this challenge. We compile programs specially so that they can be dynamically patched, and generate most of a dynamic patch automatically. Ginseng performs a series of analyses that when combined with some simple runtime support ensure that an update will not violate type-safety while guaranteeing that data is kept up-to-date. We have used Ginseng to construct and dynamically apply patches to three substantial open-source server programs--- Very Secure FTP daemon , OpenSSH sshd daemon , and GNU Zebra . In total, we dynamically patched each program with three years' worth of releases. Though the programs changed substantially, the majority of updates were easy to generate. Performance experiments show that all patches could be applied in less than 5 ms , and that the overhead on application throughput due to updating support ranged from 0 to at most 32%.

Amorphous ${\mathrm{Fe}}_{78}$${\mathrm{B}}_{12}$${\mathrm{Si}}_{10}$ in ribbon form has been investigated over a large temperature range from 4.2 to 750 K using the M\"ossbauer technique. The average isomer shift, although less than that for crystalline iron at 4.2 K, has a similar temperature dependence. The average quadrupole shift is zero below the Curie temperature ${T}_{F}$. The average hyperfine field is proportional to ${(\frac{T}{{T}_{F}})}^{\frac{3}{2}}$ for $0.03<~\frac{T}{{T}_{F}}<~0.5$, but varies more slowly for $\frac{T}{{T}_{F}}<~0.03$. The conduction electrons appear to play an important role in reducing the importance of the amorphous nature of the alloy. The magnetization of a clamped sample, nearly randomly oriented at or below room temperature, lies mainly in the plane of the ribbon between 500 and 700 K. On returning to room temperature after annealing at 706 K, the magnetization has a large out-of-plane component.
In the Search for New Anticancer Drugs, VI<sup>+</sup> Structural Modifications of Cyclophosphamide (1983)

Abstract Taking into consideration the known mechanism of the drug action of cyclophosphamide (1), several analogs and related compounds 5, 6, 7, 9, 11, 12 and 27 were synthesized, and tested against lymphocytic leukemia P 388 in mice. Moderate to high activity was found with 5 (T/C × 100 = 243 at a dose of 300 mg/kg), 7 (T/C × 100 = 155 at a dose of 55 mg/kg). None of these compounds was found to be more active than 1 (T/C × 100 = 339 at a dose of 65 mg/kg). Although the essential position C 4 for the enzymatic activation is completely blocked in 5, the compound possesses a high degree of activity. This result justifies a reevaluation of the proposed mechanism of drug action of 1 and its analogs.
