Modeling and Power Optimization of Floating Offshore Wind Farms with Yaw and Induction-based Turbine Repositioning (2019)

This paper contributes to the growing research surrounding the topic of wind farm control. Specifically, we investigate the potential of floating offshore wind turbine repositioning with the objective of maximizing the power output of a floating offshore wind farm. This investigation requires the development of a pseudo-dynamic floating offshore wind farm model that combines a modified version of the steady FLORIS wake model with a two-dimensional dynamic wind turbine model. For steady wind conditions and various mooring line lengths, optimization studies are performed using the MATLAB optimization toolbox based on the sequential quadratic programming method. The optimization goal is to determine the set of optimal axial induction factors and nacelle yaw angles of wind turbines that will maximize power production from the entire farm. For a floating offshore wind farm with a gridded 3×6 layout, a maximum relative gain of 53.5% in the wind farm efficiency is achieved. This result corresponds to a mooring line length of 925 m, which yields maximum platform surge and sway displacements of 85.8 and 69.9 m, respectively.
<title>Prototype of image compression system for medical images</title> (1990)

We previously developed an image reconstruction display for reconstructing images compressed by our hybrid compression algorithm. The hybrid algorithm, which improves image quality, applies Discrete Cosine Transform coding (DCT) and Block Truncation Coding (BTC) adaptively to an image, according to its local properties. This reconstruction display receives the compressed data from the host computer through a BMC channel and quickly reconstructs good quality images using a pipeline-based microprocessor. This paper describes a prototype of a system for compression and reconstruction of medical images. It also describes the architecture of the image compression processor, one of the components of the system. This system consists of the image compression processor, a host main-frame computer and reconstruction displays. Under this system, distributed processing in the image compression processor and the image reconstruction displays reduces the load on the host computer, and supplies an environment where the control routines for PACS and the hospital information system (HIS) can co-operate. The compression processor consists of a maximum of four parallel compression units with communication ports. In this architecture, the hybrid algorithm, which includes serial operations, can be processed at high speed by communicating the internal data. In experiments, the compression system proved effective: the compression processor compressed a 1k x 1k image in about 2 seconds using four compression units. The three reconstruction displays showed the image at almost the same time. Display took less than 7 seconds for the compressed image, compared with 28 seconds for the original image.
Improved sensitivity proteomics by postharvest alkylation and radioactive labeling of proteins (2000)

We describe approaches to improve the detection of proteins by postharvest alkylation and subsequent radioactive labeling with either [3H]iodoacetamide or 125I. Database protein sequence analysis suggested that cysteine is not suitable for detection of the entire proteome, but that cysteine alkylating reagents can increase the number of proteins able to be detected by iodination chemistry. Proteins were alkylated with β-(4-hydroxyphenyl)ethyl iodoacetamide, or with 1,5-l-AEDANS (the Hudson Weber reagent). Subsequent iodination using the Iodo-Gen system was found to be most efficient. The enhanced sensitivity obtainable by using these approaches is expected to be sufficient for visualization of the lowest copy number proteins from human cells, such as from clinical samples. However, we argue that significantly improved methods of protein separation will be necessary to resolve the large number of proteins expected to be detectable with this sensitivity.
Ru/UiO-66 Catalyst for the Reduction of Nitroarenes and Tandem Reaction of Alcohol Oxidation/Knoevenagel Condensation (2018)

A 3.1% Ru/UiO-66 material was prepared by adsorption of RuCl<sub>3</sub> from ethyl acetate on to MOF UiO-66, followed by reduction with NaBH<sub>4</sub>. The presence of acid-base and ox-red sites allows this 3.1% Ru/UiO-66 material acting as a bifunctional catalyst for the reduction of nitroarenes and tandem reaction of alcohol oxidation/Knoevenagel condensation. The high efficiency of 3.1% Ru/UiO-66 was demonstrated in the reduction of nitroarenes to amines. This system can be applied as a catalyst for at least six successive cycles without loss of activity. The 3.1% Ru/UiO-66 catalyst also was active in the tandem aerobic oxidation of alcohols/Knoevenagel condensation with malononitrile. However, the activity of this catalyst strongly decreased in the second cycle. A combination of physicochemical and catalytic experimental data indicated that Ru nanoparticles are the active sites both for the catalytic reduction of nitro compounds and the aerobic oxidation of alcohols. The activity for the Knoevenagel condensation reaction was from the existence of the "Zr <sup><i>n</i>+</sup>-O<sup>2-</sup> Lewis acid-base" pair in the framework of UiO-66.
Microspheres as Controlled-Release Systems for Parenteral and Nasal Administration (1987)

Microspheres made from natural and synthetic polymers can be used as drug delivery systems for administration by injection, ie intravenous, intramuscular and intraarticular or by the nasal route. The microspheres reach their site of action by exploitation of some suitable passive mechanism (entrapment in capillary beds or uptake by macrophages) or by a direct application into the relevant body compartment. Systems intended for use in man need to be biocompatible and biodegradable if given via the parenteral route. Possible materials include albumin, modified starch and synthetic polymers such as polylactic acid and polycyanoacrylates. A variety of microsphere systems have been investigated in vitro and in vivo and attempts have been made to overcome two major limitations of microsphere systems, namely poor entrapment (payload characteristics) and premature release (burst effect). Sustained release systems have been achieved by appropriate use of crosslinking, heat denaturation, macromolecular carriers or chemical modification. In vivo experiments exploiting the technique of gamma scintigraphy are described.
Modulation of Tumor Growth and Tumor Induced Angiogenesis After Epidermal Growth Factor Receptor Inhibition by ZD1839 in Renal Cell Carcinoma (2004)

These results suggest that the antitumor activity of ZD1839 appears to derive not only from direct inhibition of cell proliferation, but also from the inhibition of tumor angiogenesis in RCC.
The implications of post-tensioning losses on the seismic response of Pres-Lam frames (2018)

Since 2010, twelve post-tensioned timber (Pres-Lam) buildings have been constructed throughout the world. In high seismic areas, Pres-Lam technology typically combines unbonded post-tensioning tendons and supplemental damping devices to provide moment capacity to beam-column, wall-foundation or column-foundation connections. Over time creep within the timber elements leads to losses in post-tensioning forces reducing the connection moment capacity. This paper analyses how different post-tensioning loss scenarios, depending on the beam-column joint detailing, impact the building’s seismic response. Two case study buildings were designed and investigated using the Acceleration Displacement Response Spectrum (ADRS) method and Non-Linear Time History Analysis (NLTHA) to predict seismic performance. These buildings were considered to be located in areas of high and low seismic risk, leading to designs with and without the use of damping devices, respectively. The results show that the building with additional damping responded with similar peak displacements, even under extreme loss scenarios. In comparison, when supplemental damping was not used, peak displacements increased significantly with post tensioning losses.
Adsorbate-Induced Modification of the Confining Barriers in a Quantum Box Array (2017)

Quantum devices depend on addressable elements, which can be modified separately and in their mutual interaction. Self-assembly at surfaces, for example, formation of a porous (metal-) organic network, provides an ideal way to manufacture arrays of identical quantum boxes, arising in this case from the confinement of the electronic (Shockley) surface state within the pores. We show that the electronic quantum box state as well as the interbox coupling can be modified locally to a varying extent by a selective choice of adsorbates, here C<sub>60</sub>, interacting with the barrier. In view of the wealth of differently acting adsorbates, this approach allows for engineering quantum states in on-surface network architectures.
Novel Stop Sign Detection Algorithm Based on Vehicle Speed Profile (2019)

Automated driving technology involves various modern in-vehicle systems that are designed to increase road traffic safety by helping drivers gain a better awareness of the road and its potential hazards as well as other drivers around them. Stop sign detection module is an integral part of these systems as it has great utility in automated or assisted driving applications. Although promising results have been achieved in the areas of stop sign detection and classification, these methods are heavily dependent on images and image processing algorithms and detection problem in the real world remains a challenging issue. In this paper, we propose a method to detect the stop sign, based on statistical analysis of data obtained by drive history, a project conducted by Ford Motor Company. Our detection algorithm is based on the speed profile where speed is zero or close to zero. Then, we apply clustering to our data set to extract the points with this common feature. In the end, results demonstrate that our algorithm can improve the stop sign detection efficiency and afford high precision where other algorithms are prone to failure.
Selective stimulation to skin receptors by suction pressure control (2004)

In previous works, we have proposed two methods for whole palm-covering tactile display. One is suction pressure stimulation and the other is multi-primitive tactile stimulation. In those studies, we used two pressure patterns as which were considered to be significant patterns to create real tactile sensation. In this paper, we clarify the relationship between the primitives and response of mechanoreceptors using 3D FEM analysis. The results indicate that two primitives activate two superficial mechanoreceptors RA and SA I selectively.
Journey to the Center of the Cookie Ecosystem: Unraveling Actors' Roles and Relationships (2021)

Web pages have been steadily increasing in complexity over time, including code snippets from several distinct origins and organizations. While this may be a known phenomenon, its implications on the panorama of cookie tracking received little attention until now. Our study focuses on filling this gap, through the analysis of crawl results that are both large-scale and fine-grained, encompassing the whole set of events that lead to the creation and sharing of around 138 million cookies from crawling more than 6 million webpages. Our analysis lets us paint a highly detailed picture of the cookie ecosystem, discovering an intricate network of connections between players that reciprocally exchange information and include each other&#x0027;s content in web pages whose owners may not even be aware. We discover that, in most webpages, tracking cookies are set and shared by organizations at the end of complex chains that involve several middlemen. We also study the impact of cookie ghostwriting, i.e., a common practice where an entity creates cookies in the name of another party, or the webpage. We attribute and define a set of roles in the cookie ecosystem, related to cookie creation and sharing. We see that organizations can and do follow different patterns, including behaviors that previous studies could not uncover: for example, many cookie ghostwriters send cookies they create to themselves, which makes them able to perform cross-site tracking even for users that deleted third-party cookies in their browsers. While some organizations concentrate the flow of information on themselves, others behave as dispatchers, allowing other organizations to perform tracking on the pages that include their content.
Assessing graphene oxide for water desalination applications (2016)

Water desalination plays a critical role in augmenting the fresh water supplies for water scarce regions.However, despite considerable improvements in system efficiencies, it still remains six to ten times more expensive than treating freshwater for drinking.As a result, the construction and operation of a desalination plant places considerable economic burden on the regions that require such an investment.As more and more regions experience water stress due to climate change, increased industrial consumption, and population growth, materials engineering will play a role in improving the economics.The membranes used in today's reverse osmosis plants are made from polymers that are fragile, limited in the flux, and typically operate at 70% of their rated performance due to biofouling.Following the exciting proposition of using graphene as a size-exclusion based desalination membrane, there has been a great deal of revived interest in the development of new membrane materials that overcome these challenges.Graphene oxide, made from the chemical exfoliation of graphite, has served as a promising candidate for membrane applications because it is cheaper than graphene to produce and yet demonstrates similar benefits of resilience and increased permeability.In this work, we take a critical look at three aspects of graphene oxide as it applies to the development of water desalination membranes.First, we present an atomic study of the structure of graphene oxide (GO) that is produced in bulk quantities.In contrast to previous work, which has examined particularly defect free GO, we find that GO develops a nanocrystalline structure in support of a Dynamic Structural Model in its hexagonal carbon lattice.Second, we detail the development of a new cross-linker that enables the fabrication of stable GO films with sub-nanometer interlayer spacing and demonstrated nanofiltration performance.The process of cross-linking and membrane fabrication is entirely solution based and therefore promising for scale up.Finally, we evaluate the techno-economic feasibility of a GO as a water desalination material with a comparison between estimated production cost and savings in terms of the levelized cost of water.We quantitatively assess GO membranes as a scalable technology and identify other separation First, I would like to thank my advisor, Professor Jeffrey Grossman, and my committee, Professors John Lienhard and John Hart, for their dedicated guidance and feedback throughout the completion of this work.Professor Grossman is unequaled in his ability to inspire, create, develop, and assess scientific

Geometry Effects of Dielectric Barrier Discharge on a Flat Surface (2011)

We present four different shapes of dielectric barrier discharge (DBD) actuators for the inducement of fluid flow. Three-dimensional plasma governing equations have been solved based on in-house MIG flow code. We numerically test these actuators in quiescent air. Numerical results show plasma force vectors as well as detailed flow behaviors such as velocity and vorticity. Novel designs of three-dimensional (triangular, serpentine, and square) actuators produce much strong flow mixing downstream of the actuator than traditional two-dimensional (linear) actuators. Specifically, square actuator has the best performance in flow mixing than others. Three-dimensional effects such as pinching or spreading the neighboring fluid become an important index to enhance the performance of the actuator.
Expression of the photoreceptor-specific S-antigen in human retinoblastoma (1986)

This work presents an immunofluorescent study of the distribution of the photoreceptor-specific S-antigen in human retinoblastoma, using mouse monoclonal antibodies. Three cases of differentiated retinoblastoma displayed S-antigen immunoreactivity with various patterns of labeling which depended on the degree of differentiation of the area studied. Flexner-Wintersteiner rosettes and fleurettes were labeled only with monoclonal antibody S2D2, whereas undifferentiated areas were labeled with four different anti-S-antigen monoclonal antibodies, including S2D2. On the other hand, the three undifferentiated retinoblastomas did not show any labeling with these antibodies. The presence of S-antigen in differentiated retinoblastoma confirms that the origin of this tumor is from the photoreceptors, but the question remains unanswered for undifferentiated retinoblastoma for which another origin--glial or primitive neuroectodermal cells--may be proposed.
Design and Development of a Secure DICOM-Network Attached Server (2006)

It is not easy to connect a Web-based server with an existing DICOM server, and using a Web-based server on the Internet has risks. In this study, we designed and developed a secure DICOM-Network Attached Server (DICOM-NAS) through which the DICOM server in a hospital LAN was connected to the Internet. After receiving a client's image export request, the DICOM-NAS sent it to the DICOM server using the DICOM protocol. The server then provided DICOM images to the DICOM-NAS, which transferred them to the client, using HTTP. The DICOM-NAS plays an important role between the DICOM protocol and HTTP, and stores the requested images only temporarily. The DICOM server keeps all of the original DICOM images. If an unauthorized user attempts to access the DICOM-NAS, medical images cannot be accessed because images are not stored in the DICOM-NAS. Furthermore, the DICOM-NAS has features related to reporting and MPR. Therefore, the DICOM-NAS does not require a large storage capacity, but can greatly improve information security.
Process development for an effective COVID-19 vaccine candidate harboring recombinant SARS-CoV-2 delta plus receptor binding domain produced by Pichia pastoris (2023)

Recombinant protein-based SARS-CoV-2 vaccines are needed to fill the vaccine equity gap. Because protein-subunit based vaccines are easier and cheaper to produce and do not require special storage/transportation conditions, they are suitable for low-/middle-income countries. Here, we report our vaccine development studies with the receptor binding domain of the SARS-CoV-2 Delta Plus strain (RBD-DP) which caused increased hospitalizations compared to other variants. First, we expressed RBD-DP in the Pichia pastoris yeast system and upscaled it to a 5-L fermenter for production. After three-step purification, we obtained RBD-DP with > 95% purity from a protein yield of > 1 g/L of supernatant. Several biophysical and biochemical characterizations were performed to confirm its identity, stability, and functionality. Then, it was formulated in different contents with Alum and CpG for mice immunization. After three doses of immunization, IgG titers from sera reached to > 10<sup>6</sup> and most importantly it showed high T-cell responses which are required for an effective vaccine to prevent severe COVID-19 disease. A live neutralization test was performed with both the Wuhan strain (B.1.1.7) and Delta strain (B.1.617.2) and it showed high neutralization antibody content for both strains. A challenge study with SARS-CoV-2 infected K18-hACE2 transgenic mice showed good immunoprotective activity with no viruses in the lungs and no lung inflammation for all immunized mice.
Foamed bitumen in bituminous paving technology : state-of-the-art (2011)

Although foamed bitumen has been widely applied in pavement construction some of its aspects are still not yet understood. In this study, some of these aspects including: effects of the foaming process on binder chemistry, characterization of foamed bitumen and development of a rational method to optimize foam characteristics, evaluation of aggregate particle coating within foamed bitumen treated materials, and development of a gyratory compaction procedure for laterite gravels treated with foamed bitumen were addressed. The effects of the foaming process on bitumen chemistry were investigated using Fourier transform infrared spectroscopy techniques. Also, foam characteristics of three binders were established and a rational method to optimize foam characteristics proposed. Aggregate particle coating with foamed bitumen was studied using the concepts of surface energy and Rice density. In addition a gyratory laboratory compaction procedure for laterite gravels treated with foamed bitumen was established using the modified locking concept. Infrared techniques have shown that foaming does not cause any changes in the binder chemistry, suggesting that foaming may be a physical process. Further, foam characteristics are greatly influenced by binder viscosity. Also, the equiviscous temperature seems to produce foam with optimum foam characteristics. Rice density results showed that aggregate size fraction, binder expansion ratio and viscosity influenced aggregate particle coating. Surface energy results revealed that foamed bitumen exhibited better coating attributes than neat bitumen. A new compaction procedure for laterite gravels treated with foamed bitumen based on the modified locking point was developed.
Spacers and holding chambers: Not the last word, we hope (2001)

Editor,—Zar and colleagues compared homemade spacers with two commercially available valved holding chambers (VHCs) for the treatment of children with acute asthma.1 We, as the manufacturer of one of the VHCs that was evaluated, acknowledge that the practice of using empty drink bottles is common in some countries (either by necessity or choice), but we are highly concerned about the support to the hypothesis, given by implication in this paper, that coffee cup or drink bottle spacers are as effective as properly designed add on devices.

In this paper, the production technique did not simulate the release of medication from a pressurised metered dose …
Fracture Mechanic's Approach on Retardation Behaviors under Overloading (2012)

In order to clarify the effect of overload on crack growth behaviors, fatigue tests for overload were carried out for round plain specimens of SM45C steel. In the experiment, typical semi-elliptical crack shape was found and further crack growth behaviors were tested. Using three types of single overload fatigue tests, Crack growth retardation phenomenon were examined. The growth rate of surface crack(da/dN) during retardation period was analyzed in terms of and . On the growth rate of surface crack analyzed by , the dependence of overload stress levels appears. However, on the growth rate by obtained by Willenborg analysis, there is a non-liner relationship between da/dN and with narrow scatter band.
Inside Back Cover: Polyaniline‐Induced CH Arylation of Arenes with Arenediazonium Salts (Chem. Eur. J. 46/2015) (2015)

A reduced form of polyaniline induces the direct arylation of an arenediazonium salt with an arene (Gomberg–Bachmann reaction) to give the cross-coupling product, as reported by T. Amaya, T. Hirao et al. in their Full Paper on page 16427 ff. Investigation of the mechanism suggests a radical chain reaction initiated by one-electron reduction of an arenediazonium salt by the polyaniline. The cover picture likens this reaction to the ignition of a number of fireworks induced by a single burning fuse (a catalytic amount of the polyaniline as an electron donor).
