The Application of Supercapacitors Based Energy Storage Systems on Heave Compensation Systems for Offshore Lifting Equipment (2011)

An Electrical Heave Compensation System will cause large power demand fluctuations with a period time e.g. of around 8 to 12 seconds. These large power fluctuations are not desirable for the stability of the ship’s electrical power grid. This paper proposes the application and control of a supercapacitor based ESS in a power electronic system with a common DC Bus to limit the effect of the power fluctuations on the ship’s electrical power grid. The regenerated power from the heave compensation movements is temporarily stored in supercapacitors and used again when power is demanded. This causes a more constant power flow from the ship’s electrical power grid, which will cope with the losses in the system. Two topologies are discussed, namely the direct connection of the supercapacitors to the common DC bus and the indirect connection of the supercapacitors to the common DC bus through a DCDC converter. The result of the modelling and experiments of both ESS topologies shows that the high power fluctuations caused by an electrical heave compensation system are significantly decreased.
Noise reduction in a launch vehicle fairing using actively tuned loudspeakers (2003)

Loudspeakers tuned as optimal acoustic absorbers can significantly reduce damaging, low frequency, reverberant noise in a full-scale launch vehicle fairing. Irregular geometry, changing payloads, and the compliant nature of the fairing hinder effective implementation of a passively tuned loudspeaker. A method of tuning the loudspeaker dynamics in real time is required to meet the application requirements. Through system identification, the dynamics of the enclosure can be identified and used to tune the dynamics of the loudspeaker for reduction of targeted, high intensity, low-frequency modes that dominate the acoustic response in the fairing. A loudspeaker model with desired dynamics serves as the reference model in a control law designed to tune the dynamics of a non-ideal loudspeaker to act as an optimal tuned absorber. Experimental results indicate that a tuned loudspeaker placed in the nose cone of the fairing significantly reduces acoustic energy and verifies results calculated from the simulation.

Apatite formation on organic monolayers in simulated body environment (2000)

Organic monolayer films with the same functional groups as collagen were prepared by a Langmuir-Blodgett (LB) method and the LB monolayers were soaked in a simulated body fluid. Nucleation of hydroxyapatite (HA) took place on the monolayers of the carboxyl group, while no nucleation occurred on the monolayers of amino groups. From IR spectra analyses it was found that an interfacial interaction between carboxyl groups and Ca ions was important for the HA nucleation, causing the formation of HA crystals from the simulated body environment.
Photonics-based strategies for minimally invasive cancer diagnosis using endogenous and molecular contrast (2008)

Optical- and spectroscopic-based screening and imaging strategies possess unique advantages for minimally invasive cancer diagnosis. In this dissertation, we investigated how diagnostic results based on such techniques can be improved by the utilization of both endogenous and nanotechnology-facilitated molecular contrast. First, a diffusion-theory-based inversion reflectance model was constructed for the extraction of intrinsic tissue optical properties from the shape of normalized tissue diffusion reflectance spectra. The accuracy of our diffusion-based inversion algorithm was systematically assessed against Monte Carlo simulation as a function of probe geometry and tissue optical property combinations. By using this method, the spectral absorption and scattering coefficients of normal and cancerous tissue were efficiently retrieved within the center-to-center source-detector fiber separation of 0.5 mm &sim;3 mm, which is compatible with endoscopic specifications. The presented inversion approach is computationally viable for eventual real-time in vivo tissue diagnostic applications. Second, novel quantum dot nanoparticle-based contrast agents were developed for molecular and tissue imaging applications in the visible and near-infrared (NIR) spectral ranges. Specifically, lead sulfide quantum dot bioconjugates were explored as NIR contrast agents for targeted molecular imaging; a protease-activated quantum dot probe was developed to monitor specific molecular targets and pathways through optical strategies; and a phantom study was conducted to assess the utilization of lead sulfide NIR quantum dots as fluorescent contrast agents for deep tissue imaging applications. These nanoengineered exogenous probes were shown to have the potential to significantly improve the implementation of optical/spectroscopic cancer imaging techniques. Taken together, the goal of the combined projects in this dissertation was to demonstrate that photonics-based minimally invasive cancer detection and imaging methods can be greatly advanced by the utilization of both endogenous and nanotechnology-facilitated molecular contrast.
MIoT Applications for Wearable Technologies Used for Health Monitoring (2018)

In this paper we present some aspects regarding wearable devices (sensors) used for biomedical heart activity, temperature and humidity using cloud-computing services. The Internet of Things (IoT) has the objective to connect objects (electronic devices) in order to store and improve data accessibility in the worldwide. In the IoT industry, Google and Samsung dominate the market for connected objects and wearable devices. The cloud computing service used enables the linkage of the sensors (heart rate, pulse rate and moisture) data to the cloud and allows data delivery from machine-automated systems for storage, visualization, and analysis.
A Model-Fitting Approach To Cluster Validation With Application To Stochastic Model-Based Image Segmentation (1989)

An unsupervised stochastic model-based image segmentation technique requires the model parameters for the various image classes in an observed image to be estimated directly from the image. In this work, a clustering scheme is used for the model parameter estimation. Most of the existing clustering procedures require prior knowledge of the number of classes which is often, as in unsupervised image segmentation, unavailable and has to be estimated. The problem of determining the number of classes directly from observed data is known as the cluster validation problem. For unsupervised image segmentation, the solution of this problem directly affects the quality of the segmentation. In this work, we propose a model-fitting approach to the cluster validation problem based upon Akaike's Information Criterion (AIC). The explicit evaluation of the AIC is achieved through an approximate maximum-likelihood (ML) estimation algorithm. We demonstrate the efficacy and robustness of the proposed approach through experimental results for both synthetic mixture data and image data.
GROUND SURFACE ESTIMATION FROM AIRBORNE LASER SCANNER DATA USING ACTIVE SHAPE MODELS (2002)

Various filtering techniques exist to obtain the ground from laser radar data to use when building digital terrain models. This paper develops an active shape model approach to estimate the ground surface from laser radar data. The active shape model acts like a rubber cloth with elasticity and rigidity. With constraint forces the model is formed to an estimate of the ground surface. The model is glued against the measured points from underneath, forming the envelope of the point cloud. Even in a thick forest as much as 25 per cent of the data points represent the ground. The stiffness of the shape model stretches it out to a continuous surface in between the ground points. The algorithm implemented in this paper is suited to use on very dense data sets, it has been designed for data sets of more than 10 points per square meter. We propose suggestions of changes to the algorithm to adjust it to work on more sparse data sets.
NARCOLEPSY IN CHILDREN (1960)

In adult persons the narcoleptic syndrome consists of narcolepsy proper, cataplexy, sleep paralysis and hypnagogic hallucinations. The characteristics of these phenomena are discussed. The disease is not often recognized in children, although anamnestic evidence suggests that in the majority of patients the onset of the disorder is in childhood or adolescence. Data are presented concerning 16 children in whom narcolepsy was evident. Problems in diagnosis are reviewed and common pitfalls and misinterpretations are discussed. The use of analeptic drugs for treatment is outlined.
Development of a Home Screening System for Pediatric Respiratory Sleep Studies (2006)

To develop a simple and portable home screening monitor for sleep-disordered breathing (SDB) in children. In such a system, identifying the respiratory events and occurrences of motional artifacts are two essential elements that can affect the accuracy of the study. Moreover, such a system needs to be easy to set up and user friendly. The proposed system includes the following: electrocardiogram, pulse oximeter, microcontroller-based computation device, and a tri-axial accelerometer. Three physiologic parameters derived with this device were used to identify central (CE) and obstructive (OE) respiratory events. The criteria used were based on documented evidence and compared against corresponding standard polysomnographic scorings. In addition, a module was constructed in conjunction with a RS232 chip to transmit the recorded data to a personal computer. The accelerometer was used as a motion artifact detector. Detectable signals were acquired from the accelerometer when artifacts were induced on the photoplethysmography by motions in three regulated test activities lasting at least 30 seconds each. In classifying respiratory events, the combined use of oxygen saturation, heart rate, and pulse transit time to produce a complex classification (logic OR) showed promise. For OE, the sensitivity and specificity were 0.828 and 0.859, respectively. For CE, these values were 0.868 and 0.762, respectively. The proposed system potentially fulfils the criterion as a home screening tool and can form an indispensable addition to the SDB investigation in the pediatric population.
Plane-wave DFT-LDA calculation of the electronic structure and absorption spectrum of copper (2001)

We present an accurate, first-principles study of the electronic structure and absorption spectrum of bulk copper within density functional theory in the local density approximation, including the study of intraband transitions. We construct norm-conserving pseudopotentials (PP's) including the $3d$ shell (and optionally the underlying $3s$ and $3p$ shells) in the valence and requiring a relatively small plane-wave basis (60 and 140 Ry cutoff, respectively). As a consequence, these PP's are strongly nonlocal, yielding macroscopically wrong results in the absorption spectrum when momentum matrix elements are computed naively. Our results are compared with experimental photoemission, absorption, and electron energy loss data, and suggest nontrivial self-energy effects in the quasiparticle spectrum of Cu.
Induction of cytochrome P-450 and 5-aminolevulinate synthase activities in cultured rat hepatocytes. (1990)

Cytochromes P-450IIB1 and P-450IIB2 were recently shown to be inducible in rat hepatocyte cultures maintained on a reconstituted extracellular tumor matrix (Matrigel) as indicated by increases in P-450IIB1 and -IIB2 mRNAs and immunoreactive proteins (J. Cell. Physiol., 134: 309-323, 1988). Here we show that treatment of cultured rat hepatocytes with phenobarbital and other compounds known to induce P-450IIB1/2 in vivo increased spectral cytochrome P-450, immunoreactive proteins, and benzyloxy- and pentoxy-resorufin dealkylases, activities known to be specific for cytochrome P-450IIB1/2. These increases were observed when cells were cultured on either Matrigel or collagen matrix in Williams E medium. Cytochrome P-450III was also increased by phenobarbital and dexamethasone on either matrix. Propoxycoumarin depropylase activity, which has been proposed as a specific activity catalyzed by cytochrome P-450III, was increased 3-4-fold more by treatment with 3-methylcholanthrene than by phenobarbital or dexamethasone. The activity catalyzed by P-450III could be distinguished from that catalyzed by other P-450 forms using the specific inhibitor triacetyloleandomycin. Benzoyloxyresorufin dealkylase was also increased in these cells by treatment with 2,4,5,2',4',5'-hexachlorobiphenyl, glutethimide, or mephenytoin. Treatment with phenobarbital or 2-allyl-2-isopropylacetamide slightly induced 5-aminolevulinate synthase activity. 5-Aminolevulinate synthase activity was slightly increased in cells treated with phenobarbital or 2-allyl-2-isopropylacetamide. Succinyl acetone also induced 5-aminolevulinate synthase activity and, in combination with either of the other two drugs, synergistically increased the enzyme activity regardless of whether cells were cultured on collagen or Matrigel. These results indicate that with simple and economical enzyme assays for holocytochrome P-450 and 5-aminolevulinate synthase, the rat hepatocyte culture system can be used for studies of the interrelationships between phenobarbital induction of cytochrome P-450 and heme metabolism.

Status of the Sulzer Hexis Product Development (1999)

Sulzer has been involved, since 1991, in the development of SOFC (Solid Oxide Fuel Cell) technology. Founded in 1997, Sulzer Hexis Ltd. is preparing the market entry of fuel cell systems for residential applications. Such systems will supply the basic electrical power of single and multi family houses. The exhaust gas from the fuel cell module is coupled with a conventional heating/cooling unit. This combination of electricity and heat production is the key to a more efficient utilization of fossil fuels. It exceeds by far the combination of conventional central power stations and decentralized heating equipment. From 1998 to 2000, Sulzer Hexis will perform field tests. Several gas suppliers and city utilities in Switzerland, Germany and Japan are supporting these efforts. With the help of the experience gained from the current field tests, Sulzer Hexis is developing a prototype fuel cell unit which will be launched in the market in 2001.
Bradyrhizobium japonicum nodulation genetics (1995)

Studies of the genetics of nodulation by Bradyrhizobium japonicum have revealed many similar features with Rhizobium and Azorhizobium species, but also apparent differences.The regulation of nod gene expression in B. japonicum is complex, involving the interplay of the positive regulator, NodD,, as well as a repressor, NolA.A unique feature of B. japonicum is the involvement of a two-component regulatory system, NodV and NodW, in the control of nod gene expression.It is not clear why B. japonicum requires this level of complexity to control nod gene transcription.The nod gene products encode the biosynthesis of substituted lipo-chitin Nod signals that induce many of the early nodulation events.B. japonicum and B. ekanii produce a large variety of such Nod signals.The basic structure of the Nod signal, an acylated oligomer of N-acetylglucosamine, is synthesized through the action of NodA, NodB, and NodC.Various substitutions of this basic structure confer host specificity to the molecule.For example, in B. japonicum, the nodZ gene product is essential for fucosylation of the terminal, reducing N-acetylglucosamine residue.These observations argue for the interaction of a substituted Nod signal with a specific plant receptor molecule.However, structure/function studies using chemically synthesized Nod signal molecules suggest a more complex interaction between chain length and specific substitution.These findings leave open the possibility that a general chitin receptor may function in a unique way to elicit nodule formation.The novel features discovered through the study of B. japonicum contribute to our general understanding of nodulation and to the larger question of plant cell signal transduction.
IGF-I elicits growth of human intestinal smooth muscle cells by activation of PI3K, PDK-1, and p70S6 kinase (2003)

Endogenous IGF-I regulates growth of human intestinal smooth muscle cells by jointly activating phosphatidylinositol 3-kinase (PI3K) and ERK1/2. The 70-kDa ribosomal S6 kinase (p70S6 kinase) is a key regulator of cell growth activated by several independently regulated kinases. The present study characterized the role of p70S6 kinase in IGF-I-induced growth of human intestinal smooth muscle cells and identified the mechanisms of p70S6 kinase activation. IGF-I-induced growth elicited via either the PI3K or ERK1/2 pathway required activation of p70S6 kinase. IGF-I elicited concentration-dependent activation of PI3K, 3-phosphoinositide-dependent kinase-1 (PDK-1), and p70S6 kinase that was sequential and followed similar time courses. IGF-I caused time-dependent and concentration-dependent phosphorylation of p70S6 kinase on Thr(421)/Ser(424), Thr(389), and Thr(229) that paralleled p70S6 kinase activation. p70S6 kinase(Thr(421)/Ser(424)) phosphorylation was PI3K dependent and PDK-1 independent, whereas p70S6 kinase(Thr(389)) and p70S6 kinase(Thr(229)) phosphorylation and p70S6 kinase activation were PI3K dependent and PDK-1 dependent. IGF-I elicited sequential Akt(Ser(308)), Akt(Ser(473)), and mammalian target of rapamycin(Ser(2448)) phosphorylation; however, transfection of muscle cells with kinase-inactive Akt1(K179M) showed that these events were not required for IGF-I to activate p70S6 kinase and stimulate proliferation of human intestinal muscle cells.
Stability evaluation of freeze-dried Lactobacillus paracasei subsp. tolerance and Lactobacillus delbrueckii subsp. bulgaricus in oral capsules. (2012)

Freeze-drying is a common preservation technology in the pharmaceutical industry. Various studies have investigated the effect of different cryoprotectants on probiotics during freeze-drying. However, information on the effect of cryoprotectants on the stability of some Lactobacillus strains during freeze-drying seems scarce. Therefore, the aim of the present study was to establish production methods for preparation of oral capsule probiotics containing Lactobacillus paracasei subsp. tolerance and Lactobacillus delbrueckii subsp. Bulgaricus. It was also of interest to examine the effect of various formulations of cryoprotectant media containing skim milk, trehalose and sodium ascorbate on the survival rate of probiotic bacteria during freeze-drying at various storage temperatures. Without any cryoprotectant, few numbers of microorganisms survived. However, microorganisms tested maintained higher viability after freeze-drying in media containing at least one of the cryoprotectants. Use of skim milk in water resulted in an increased viability after lyophilization. Media with a combination of trehalose and skim milk maintained a higher percentage of live microorganisms, up to 82%. In general, bacteria retained a higher number of viable cells in capsules containing freeze-dried bacteria with sodium ascorbate after three months of storage. After this period, a marked decline was observed in all samples stored at 23°C compared to those stored at 4°C. The maximum survival rate (about 72-76%) was observed with media containing 6% skim milk, 8% trehalose and 4% sodium ascorbate.
