Integrating health management into legacy platforms (2009)

Owners and operators of air and space vehicles frequently desire to retrofit health management technology onto their platforms. Prognostics and condition based maintenance processes offer the promise of higher availability, reduced operating costs, and improved maintenance efficiency. An effective health management system, judiciously applied, can positively impact these goals, but to be effective it can require significant integration effort at the component, subsystem, system, vehicle, and fleet levels. Once in operation, aerospace vehicles present unique challenges for integration of modern health management technology. This paper identifies the motivations, challenges, and technologies to successfully integrate health management into existing platforms. The primary factors that influence the success of health management system integration are identified. Clearly, common and ubiquitous standards would enable significant reductions in this integration cost and make IVHM (Integrated Vehicle Health Management) technology practical in more applications. Specific integration approaches involving high bandwidth sensors, wireless communications, and partitioning of onboard processing were prototyped and are described as well as the impact of open standards to reduce integration costs and enable greater access to technology from industry, academia and government organizations.

Complete algorithms for reorienting polyhedral parts using a pivoting gripper (2002)

To rapidly feed industrial parts on an assembly line, Carlisle et. al. (1994) proposed a flexible part feeding system that drops parts on a flat conveyor belt, determines the pose of parts with a vision system and manipulates them into a desired pose. A robot arm with 4-DOF is capable of moving parts through 6-DOF when equipped with a passive pivoting axis between the parallel jaws of its gripper. We refer to these actions as pivot grasps. This paper considers the planning problem. Given a polyhedral part shape, coefficient of friction and a pair of stable configurations as input, find pairs of grasp points that will cause the part to pivot from one stable configuration to the other. For some transitions, pivot grasps may not exist. For a part with n faces and m stable configurations, we give an O(m/sup 2/n log n) algorithm to generate the m/spl times/m matrix of pivot grasps. When the part is star shaped, this reduces to O(m/sup 2/n). We also study a generalization that considers "capture regions" around stable configurations. Both algorithms are complete in that they are guaranteed to find pivot grasps when they exist.
Big data-empowered system for automatic trouble ticket generation in IoT networks (2019)

One of the major concerns for a mobile network operator is the customer trouble ticket (TT) management, as it is directly related to the customers' satisfaction about the provided quality of service. This issue becomes specially relevant when the number of end devices being served by the cellular network increases dramatically. Such is the case of communications under the Internet of Things (IoT) paradigm. In this case, a traditional approach for TT management appears as insufficient and novel mechanisms for TT management need to be devised. This work proposes a big data-empowered framework for automatic TT generation, showing its capability to deal with such amount of data. Results in a live network providing IoT communication show that the proposed framework was able to identify the network anomalies that were identified following a traditional approach as well as many others that remained hidden under that approach.

Donor Site Morbidity After Anterior Iliac Crest Bone Harvest for Single-Level Anterior Cervical Discectomy and Fusion (2003)

A large percentage of patients report chronic donor site pain after anterior ICBG donation, even when only a single-level ACDF procedure is performed. Moreover, long-term functional impairment can also be significant. Patients should be counseled regarding these potential problems, and alternative sources of graft material should be considered.
Unconventional Inorganic‐Based Memristive Devices for Advanced Intelligent Systems (2019)

Abstract The latest progresses in software engineering such as cloud computing, big data analysis, and machine learning have accelerated the emergence of advanced intelligent systems (AIS). However, the current computing system has significant challenges in dealing with unstructured data (e.g., image, voice, physiological signals) because the von‐Neumann bottleneck induces latency and power consumption issues. Neuromorphic computing, which imitates the behaviors of neuron and synapse within the biological neural network, is considered a promising solution beyond von‐Neumann architecture, since its collocated structure of processor and memory enables parallel processing of unstructured data with remarkable efficiency. Memristors are considered as next‐generation nonvolatile memory devices due to fast speed, low power, and excellent scalability. However, a low reliability and leakage current issues remain as obstacle to the commercialization of memristors. Memristive devices have been widely investigated as a strong candidate for artificial synapses since their resistance modulation characteristics under electrical stimulus are analogous to the plasticity of the brain synapse. Although emulation of synaptic behavior by single memristor cells is demonstrated by many researchers, the development of fully functional memristive neural network requires further investigations. This paper introduces the recent advances and developments in the field of inorganic‐based unconventional memristive devices for future AIS applications.
Phase Shifting Point Diffraction Interferometry of Lithographic Optics (1996)

The Center for X-Ray Optics is performing metrology of optics intended to be used for lithography at wavelengths in the Extreme Ultraviolet (EUV) range. The source for this radiation is an undulator operating at the Advanced Light Source (ALS). Initially a Point Diffraction Interferometer (PDI) was used and the experience acquired with this instrument led to the development of a new interferometer, the Phase Shifting Point Diffraction Interferometer (PSPDI), to be described in this paper.
Enhanced Bipolar Electrochemistry at Solid-State Micropores: Demonstration by Wireless Electrochemiluminescence Imaging (2019)

Bipolar electrochemistry (BPE) is a powerful method based on the wireless polarization of a conductive object that induces the asymmetric electroactivity at its two extremities. A key physical limitation of BPE is the size of the conductive object because the shorter the object, the larger is the potential necessary for sufficient polarization. Micrometric and nanometric objects are thus extremely difficult to address by BPE due to the very high potentials required, in the order of tens of kV or more. Herein, the synergetic actions of BPE and of planar micropores integrated in a microfluidic device lead to the spatial confinement of the potential drop at the level of the solid-state micropore, and thus to a locally enhanced polarization of a bipolar electrode. Electrochemiluminescence (ECL) is emitted in half of the electroactive micropore and reveals the asymmetric polarization in this spatial restriction. Micrometric deoxidized silicon electrodes located in the micropore are polarized at a very low potential (7 V), which is more than 2 orders of magnitude lower compared to the classic bipolar configurations. This behavior is intrinsically associated with the unique properties of the micropores, where the sharp potential drop is focused. The presented approach offers exciting perspectives for BPE of micro/nano-objects, such as dynamic BPE with objects passing through the pores or wireless ECL-emitting micropores.
Photoresponsive Liquid Crystals: Photoresponsive Structural Color in Liquid Crystalline Materials (Advanced Optical Materials 16/2019) (2019)

Photoresponsive liquid crystalline photonic materials are a promising class of smart materials in which the self-regulation of light can occur. In article number 1900429, Michael McConney and coworkers review the current state of the art of these unique self-assembling materials and the techniques used to produce photosensitive structural color in liquid crystalline materials.
TBIOM Special Issue on “Best Reviewed Papers From IJCB 2020—Editorial” (2021)

Recent years have seen considerable advances in biometric recognition techniques leading to a wide-spread deployment of biometric technology across a number of application domains, ranging from security, border control, and criminal investigations to entertainment, social media, autonomous driving and even health services. To highlight some of these advancements and present the latest research achievements related to biometrics, the 4th IEEE/IAPR International Joint Conference on Biometrics (IJCB) was organized in 2020. IJCB combines two major biometrics research conferences, the IEEE International Conference on Biometrics Theory, Applications and Systems (BTAS) conference, and the International Conference on Biometrics (ICB) and is made possible through a special agreement between the IEEE Biometrics Council and the IAPR TC-4. Because IJCB has (so far) only been organized every three years, it represents a particularly prestigious and selective event, where only the highest-quality research is presented.
On the Performance of LMS-Based Algorithms for the Identification of Low-Rank Systems (2020)

A recent approach has been proposed that exploits the nearest Kronecker product (NKP) decomposition in conjunction with low-rank approximation methods, for efficiently solving low-rank system identification problems. Following this idea, several adaptive filtering solutions were developed. In this paper, we focus on least-mean-square (LMS) algorithms based on NKP, which own the advantage of low computational complexity. The performance features of these LMS-based algorithms are briefly investigated and a variable step-size (VSS) version is derived. The proposed VSS algorithm achieves a better compromise in terms of the main performance criteria.

An Optimal Control Strategy for LCL Tuned Inductive Power Transfer (IPT) Systems (2021)

Conventional dual and triple variable control approaches do not offer optimal performance for Wireless power transfer (WPT) systems based on inductive power transfer (IPT) technology, particularly for applications where the system is subjected to variations in the magnetic coupling, component values, and power levels. This paper proposes a four-variable optimal control strategy for LCL compensated (tuned) bidirectional IPT (BD-IPT) systems. The proposed control strategy, which ensures power regulation at maximum possible efficiency despite any changes in coupling and power levels, is described in detail, and a mathematical model is presented to investigate its performance. Simulated results of a 1kW BD-IPT system are also presented, benchmarking against conventional control methods, to demonstrate that the proposed control strategy offers superior performance even under large variations in system parameters.
Disassembly for recycling of office electronic equipment (1997)

Office electronic equipment continues to proliferate, and to be discarded, for a variety of reasons. This paper outlines the magnitude of the problem and shows why we have chosen PC's as our major consideration. The problems associated with discarding PC's are implied by or embodied in various details of PC's and in the customs of their use. These details and the manners in which they affect the disposal issue are reviewed in the third section. The fourth section presents the key issues affecting the scrapping of computers and what is done in Europe and USA. The fifth section is an attempt to try to capture and predict what the future may bring regarding the goal of reducing electronic office machinery mass going to the landfill. Policy issues are reviewed in the last section.
Multiplex design for high-performance microspectrometers (2005)

The volume of spectrometers can be drastically reduced through the use of multiplex measurement. Reductions of 3-5 orders of magnitude are possible. This has the potential to drastically effect manufacturing and deployment costs.
Significance of tractor-trailer impacts to the rear of light vehicles (2022)

This study provides insight into the striking vehicle or object associated with serious injury to light vehicle occupants in rear impacts. Tractor-trailer impacts into the rear of a vehicle involved a high risk for serious injury in the struck vehicle. The use of collision mitigation technologies, such as forward collision warning or automatic emergency braking, on the tractor-trailer may support better speed control and lead to lower closing velocities of rear impacts to light vehicles.
The Interaction of C-17 Esters of Estradiol with the Estrogen Receptor* (1984)

Various C-17 alkyl esters of estradiol (E2) were tested as ligands for the estrogen receptor. The naturally occurring fatty acid esters, represented by E2-17-stearate, E2-17-palmitate, and E2-17-arachidonate, did not compete with [3H]E2 for receptor-binding sites. [3H]E2-17-stearate did not bind in a specific or saturable manner to uterine cytosol. On the other hand, the long-acting pharmacological esters of E2, E2-17-acetate, -propionate, -valerate, etc., were highly effective in competing for the binding of [3H]E2 to the uterine receptor. However, it was found that these short chain esters were hydrolyzed to E2 when incubated with uterine cytosol under the conditions used for the binding assay. Consequently, [3H]E2-17-acetate and [3H] E2-17-valerate were tested as ligands in an assay in which the hydrolytic activity was minimized by partially purifying the receptor with (NH4)2SO4 precipitation and by limiting the duration of the incubation. In this assay there was no specific binding of the C-17-valerate ester. There was a relatively small amount of specifically bound radioactivity in the incubation of the acetate ester, but upon high performance liquid chromatographic analysis, the specifically bound steroid was found to be E2 and not the ester. These results indicate that the C-17 esters of E2, from C2 to the long chain fatty acids, all of which are potent long-acting estrogens, exert their estrogenic effects only after hydrolysis to the free C18 steroid.
Spatially consistent pathloss modeling for millimeter-wave channels in urban environments (2016)

This paper consider a fundamental issue of pathloss modeling in urban environments, namely the spatial consistency of the model as the mobile station (MS) moves along a trajectory through street canyons. We show that the traditional model of power law pathloss plus lognormally distributed variations can provide misleading results that can have serious implications for system simulations. Rather, the pathloss coefficient has to be modeled as a random variable that changes from street to street, and is also a function of the street orientation. Variations of the channel gain, taken over the ensemble of the whole cell (or multiple cells) thus consist of the compound effect of these pathloss coefficient variations together with traditional shadowing variations along the trajectory of movement. Ray tracing results demonstrate that ignoring this effect can lead to a severe overestimation of shadowing standard deviation. While the effect is irrelevant for “drop-based” simulations, it can have critical impact on system simulations that require spatial consistency for large-scale movement, such as most mm-wave systems.
Anisotropy Field and Electrical Resistivity in Magnetically Soft Co-Pd-Si-O Thin Films (1999)

A study was made of the properties and structure of Co-Si-Pd-O based films, prepared by reactive sputtering method Soft magnetic properties are found in the films with O content at the percolation threshold, and realized in the composition range more than 2%Si and 5%Pd in Co- Si-Pd-(O) pseudo-ternary system films. A larger Hk than 200 Oe is attained in the soft magnetic films near 8%Si and more than 10%Pd, where ρ is about 1000 μΩcm. The compositional dependence of these properties except Hk can be explained by the structure change with composition. A large Hk can be easily controlled by magnetic annealing from 0 to more than 200 Oe, which originates in the induced magnetic anisotropy.
Umbilical cord‐blood transplantations from unrelated donors in patients with inherited metabolic diseases: Single‐institute experience (2008)

We evaluated the feasibility of UCBT from unrelated donors and a myeloablative preparative regimen that did not involve anti-thymocyte globulin in five children with lysosomal and peroxisomal diseases. Patients with MPS II (n = 1), adrenoleukodystrophy (n = 1), metachromatic leukodystrophy (n = 2), and Krabbe disease (n = 1) received UCBT between December 2001 and September 2005. All patients received oral Bu (600 mg/m2), CY (200 mg/kg IV), and fludarabine (180 mg/m2 IV). Prophylaxis for GVHD consisted of a combination of tacrolimus and a short methotrexate course. Neutrophil engraftment occurred a median of 24 days (range, 21-25) after transplantation. None had graft rejection. One patient developed grade III acute GVHD and the other four patients had grade I acute GVHD; none had extensive chronic GVHD. One patient developed hemorrhagic cystitis. There were no treatment-related deaths. Although one child with MPS II died of PTLD 10 months after the UCBT, four of the five children are alive 14, 20, 31, and 55 months after transplantation with complete donor chimerism. These results suggest the feasibility of the UCBT with Bu, fludarabine, and CY-preparative regimen for patients with inherited metabolic diseases.
Implementation of active direction-pass filter on dynamically reconfigurable processor (2005)

In this paper, we report the design and implementation of a sound source separation system using a dynamically reconfigurable device. A robot in real-world environments should have an ability to treat a mixture of multiple sound signals. Active direction-pass filter (ADPF) which extracts sound from a specific direction by using a pair of microphones has been developed as such a method of sound source separation. The ADPF was used as a front-end for an automatic speech recognition system, and recognition of three simultaneous speech signals has been reported. The ADPF, however, requires a lot of computational power, while the battery capacity and the physical size of the robot are limited. To reduce the power consumption and the size of the system, we adopted the dynamically reconfigurable device, DRP developed by NEC Electronics. We implemented the ADPF on DRP, and investigated the effectiveness of dynamically reconfigurable device for these applications. The preliminary experiment shows that ADPF on DRP separates a mixture of sound sources in real-time with practical accuracy.
<title>Experimental characterization of Ni-Ti shape memory alloy wires under complex loading conditions</title> (1999)

Shape memory alloys (SMAs) have shown promise as high-force, high displacement actuators. Critical issues such as path- dependence, predictability and sensitivity to testing conditions, however, need to be addressed in order to design controllable actuators using SMAs. This paper presents research aimed at addressing some of design issues involving application of SMAs, particularly at actuators. Quasistatic experiments at constant stress, strain and temperature are consolidated on a critical stress-temperature diagram to delineate the regions of stability of the various phases of the material. The critical points from these quasistatic tests are found to be in excellent agreement with each other, and correlate relatively well with the constitutive models for SMA thermomechanical behavior. It is also observed that the state of the material is not unique at points along the transformation, and is dependent on the history of the material before the start of the test, individual test involved, the method of loading, and loading rates. Significant variation of the state of the material with different rates and conditions of loading are shown to further illustrate this point. This behavior is likely to be decisive in determining the dynamic behavior of the material, and underscores the need for approaches incorporating these issues for design of repeatable actuators.
EXAFS Spectroscopy Studies of Cation Local Environment in Sodium-Neutralized Ethylene Copolymer Ionomers (2001)

Extended X-ray absorption fine structure (EXAFS) spectroscopy was used to study the local environment around sodium in ethylene−methacrylic acid (E−MAA) and ethylene−acrylic acid (E−AA) copolymer ionomers. Substantial changes occur in the arrangement of atoms around sodium as the neutralization level changes from ∼20% to 80%, unlike zinc ionomers where the arrangement basically does not change over this range of neutralization levels. In E−MAA ionomers, changes in EXAFS patterns were consistent with the environment around sodium becoming less uniform with increasing neutralization level while the reverse was true for E−AA ionomers. This difference in the sodium ionomers was unexpected and surprising, particularly since the amount of water absorbed per sodium cation did not depend on acid comonomer identity. In E−AA ionomers neutralized with both zinc and sodium, the environment around sodium becomes substantially more ordered vs the environment of the equivalent material neutralized only with sodium. This result is consistent with the formation of a single type of zinc−sodium mixed aggregate consistent with EXAFS studies at the zinc edge. In E−MAA mixed-cation ionomers, the environment becomes more disordered upon addition of zinc, also consistent with studies at the zinc edge.
