Real-time economic nonlinear model predictive control for wind turbine control

ABSTRACT Nonlinear model predictive control (NMPC) is a strong candidate to handle the control challenges emerging in the modern wind energy industry. Recent research suggested that wind turbine (WT) control based on economic NMPC (ENMPC) can improve the closed-loop performance and simplify the task of controller design when compared to a classical NMPC approach. This paper establishes a formal relationship between the ENMPC controller and the classic NMPC approach, and compares empirically their closed-loop nominal behaviour and performance. The robustness of the performance is assessed for an inaccurate modelling of the tower fore-aft main frequency. Additionally, though a perfect wind preview is assumed here, the effect of having a limited horizon of preview of the wind speed via the LIght Detection And Ranging (LIDAR) sensor is investigated. Finally, this paper provides new algorithmic solutions for deploying ENMPC for WT control, and report improved computational times.
Distribution of allotypic specificities A1, A2, A14, and A15 among immunoglobulin G molecules.

The distribution of specificities A1, A2 (Fd-associated allotypes of rabbit heavy chains), A14 and A15 (Fc-associated allotypes of rabbit γ chains) was studied using 125I-labeled IgG from homozygous and heterozygous rabbits of known pedigree. The IgG of an A1, 14/A2, 15 rabbit whose pedigree showed that A1 was genetically associated with A14 had closely similar proportions of these two specificities (80%), whereas IgG of an A1, 15/A2, 14 rabbit with A2 in coupling with A14 had equal proportions of these two specificities (20%). A rabbit with suppressed phenotypic expression of the A1 allotype was also suppressed for the A14 to which it was coupled. The quantitative expression of the Fc allotype (A14 or A15) is influenced by the Fd allotype with which it is genetically associated. The binding experiments indicated that the genetic association between Fd and Fc allotypes was faithfully reproduced in at least 90% to 95% of γ chains and a search for “recombinant” molecules (A1 with A14 and A15 in an A1, 14/A2, 15 heterozygote) was negative within the limits of the method (5% to 10%). Although a preliminary report (1) suggested that such molecules did occur, these low figures seem to indicate that the formation of “recombinant” molecules which utilize the genetic information for the Fd region from one homologous chromosome and for the Fc region from the other cannot play a major role in generating the diversity of antibody heavy chains.
New anticoagulants and regional anesthesia

Purpose of review The use of pharmacological thromboprophylaxis in the perioperative period may conflict with regional anesthetic techniques in which maintaining hemostatic integrity is essential. Recently, new anticoagulants have been developed with more efficacy and a better safety profile. This article reviews the basis for the actual recommendations and the current status and management of these new drugs. Recent findings Recent studies have outlined that the risk of epidural hematoma after neuraxial anesthesia may be higher than estimated. Therefore, it is imperative to follow the published recommendations. The use of new anticoagulant drugs may take into account the pharmacological profile of each one to safely perform regional anesthesia, mainly the time to reach peak plasma level and half-life. Summary When new anticoagulant drugs are used for thromboprophylaxis in orthopedic surgery, the performance of neuraxial anesthetic techniques should be based on their pharmacology. If a peripheral blockade is chosen, these recommendations should be followed when a block is performed in a noncompressible area.
High-Speed Interconnection for VLSI Systems Using Multiple-Valued Signaling with Tomlinson-Harashima Precoding

The data rate of VLSI interconnections has been increasing according to the demand for high-speed operation of semiconductors such as CPUs. To realize high performance VLSI systems, high-speed data communication has become an important factor. However, at high-speed data rates, it is difficult to achieve accurate communication without bit errors because of inter-symbol interference (ISI). This paper presents highspeed data communication techniques for VLSI systems using TomlinsonHarashima Precoding (THP). Since THP can eliminate the ISI with limiting average and peak power of transmitter signaling, THP is suitable for implementing advanced low-voltage VLSI systems. In this paper, 4-PAM (Pulse amplitude modulation) with THP has been employed to achieve high-speed data communication in VLSI systems. Simulation results show that THP can remove the ISI without increasing peak and average power of a transmitter. Moreover, simulation results clarify that multiple-valued data communication is very effective to reduce implementation costs for realizing high-speed serial links. key words: high-speed interface, Tomlinson-Harashima precoding (THP), intersymbol interference, multiple-valued signaling, low-voltage VLSI systems

Sequence comparisons of HTLV‐I from HAM/TSP patients and their asymptomatic spouses

We amplified and sequenced portions of the human T-lymphotropic virus type I (HTLV-I) (U3), pol, env, and pX provirus regions (1212 bp per person) from peripheral blood lymphocytes (PBL) of two married couples (case 1 and case 2). Both husbands are patients with HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP), and the wives are asymptomatic HTLV-I carriers. We selected these regions because the LTR and env regions of murine retrovirus models have been involved in determining tissue tropism. In addition, the predominant im-munogenic epitope for HTLV-I-specific cytotoxic T cells obtained from circulating PBL of HAM/TSP patients was localized in the HTLV-I pX region. Our aim was to examine variations in these HTLV-I regions between affected and asymptomatic spouses. In the HTLV-I regions studied, we detected no sequence variation between each couple. These data do not favor the hypothesis that neurotropic mutants of HTLV-I are involved in the pathogenesis of HAM/TSP.
Is Simplicity Evidence of Truth?1

In a short 1997 book entitled Simplicity as Evidence of Truth, the Oxford philosopher Richard Swinburne has put forward the following thesis summarily: ‘… for theories (of equal scope) rendering equally probable our observational data (which, for brevity I shall call equally good at “predicting”), fitting equally well with background knowledge, the simplest is most probably true’.

Sum-rate based opportunistic relay selection method for a dual-hop multiple half/full-duplex bi-directional wireless relaying networks

This paper investigates the opportunistic relay selection method for bi-directional wireless relaying networks. The investigation considers a dual-hop network with a multiple half/full-duplex two-way relay terminal in the system model. The sum-rate based opportunistic relay selection (SR-ORS) strategy selects the best relay terminal based on maximum sum-rate of user-pair and related relay terminal. According to analytical, asymptotic and Monte-Carlo simulation results, the SR-ORS strategy provides better performance results when the relay terminal operates in full-duplex mode.
Expression of Microbiota, Toll-like Receptors, and Their Regulators in the Small Intestinal Mucosa in Celiac Disease

Objectives: Less than one-tenth of the carriers of the risk genes HLA-DQ2 or HLA-DQ8 develop celiac disease, suggesting that other genetic and environmental factors are important in the pathogenesis. The role of gut microbiota has been addressed previously with inconsistent findings. Our aim was to evaluate microbiota, its receptors (Toll-like receptors [TLRs]), and regulators of the TLRs in the small intestinal mucosa in celiac disease. Methods: Microbiota was analyzed by quantitative polymerase chain reaction (total bacteria and 10 bacterial group- and species-specific primers) and gene expression of interleukin-8 (IL-8), TLR2, TLR3, TLR4, TLR5, TLR9, and regulators of TLRs, Toll-interacting protein (TOLLIP), and single immunoglobulin IL-1R–related molecule, by relative quantitative reverse transcription-polymerase chain reaction in 10 children with celiac disease (untreated celiacs), 9 children with normal small intestinal mucosa (controls), and 6 adults with celiac disease with normal small intestinal mucosa after following a gluten-free diet (treated celiacs). Results: Small intestinal microbiota was comparable among controls, untreated celiacs, and treated celiacs. Expression of IL-8 mRNA, a marker of intestinal inflammation, was significantly increased in untreated celiacs as compared with treated celiacs (P = 0.002) and controls (P = 0.001). Expression of TLR-2 mRNA was significantly decreased in untreated (P = 0.001) and treated (P = 0.03) celiacs, whereas expression of TLR-9 mRNA was increased in untreated celiacs (P = 0.001) as compared with controls. Expression of TOLLIP mRNA was downregulated in untreated celiacs as compared with controls (P = 0.02). Conclusions: Altered gene expression of TLR2, TLR9, and TOLLIP in small intestinal biopsies in celiac disease suggests that microbiota-associated factors may be important in the development of the disease.
Adhesion of Streptococcus Mutans to Different Restorative Materials

Adherence of oral bacteria to the surface of dental restorative materials is considered an important step in the development of secondary caries and periodontal disease. The aim of this study was to investigate and compare the adherence of different restorative materials to Streptococcus mutans strain (CCUG35176) in order to ascertain possible differences. The materials tested ranged across different classes including: flowable composites (Gradia Direct LoFlo; Filtek Supreme XT Flowable), anterior composites (Gradia Direct Anterior), universal composites (Filtek Supreme XT), packable composites (Filtek Silorane; Filtek P60), glass-ionomers (Fuji IX Gp Extra; Equia) and a control reference material (Thermanox plastic coverlips). Bacterial suspension was deposited onto each material and the adhesion was evaluated trough the colony forming units (CFUs) determination. Packable silorane-based composite was found to be less adhesive than posterior packable composite P60, flowable composites and glass ionomers. The fluoride of glass ionomers did not prevent the attachment of S. mutans; furthermore, after roughness analysis and SEM investigations, the hypothesis that the difference in bacterial adhesion can be determined by the particular surface chemistry of the material itself as well as by different electrostatic forces between bacteria and restorative surfaces must be given serious consideration.
Development of Allergic Conjunctivitis Induced by House Dust Mite Extract From Dermatophagoides pteronyssinus.

PURPOSE The purpose of this study was to develop a murine model of allergic conjunctivitis induced by house dust mite (HDM) extract from Dermatophagoides pteronyssinus, a major allergen in humans. METHODS Forty BALB/c mice were divided into five groups, immunized with placebo, ovalbumin (10 μg), or HDM extract following a schedule. Twenty minutes after topical challenge, mice were examined clinically. Material collected from mice was used for measuring total and specific IgE, antigen-specific lymphocyte proliferation, and supernatant cytokine levels and for conjunctival histopathology and flow cytometric analysis of conjunctival cells. RESULTS This murine model showed similar clinical signs and laboratory findings to human allergy and the ovalbumin-induced allergic conjunctivitis model. Total IgE levels and conjunctival infiltration of mast cells and eosinophils in immunized mice were significantly higher than in the control group. Cervical lymphocyte proliferation was increased in antigen-stimulated cultures in immunized mice, concomitant with significantly higher IL-4 and IL-5 levels in the culture supernatant. The proportion of conjunctival CD4+ T cells expressing the ST2 receptor was increased, and conjunctival CD4+ST2+ T cells exhibited an increase in intracellular IL-5. CONCLUSIONS House dust mite extract successfully induced allergic conjunctivitis in BALB/c mice. Ten micrograms of HDM extract was the optimal dose for systemic immunization in this model. This murine model is suitable for further studies on HDM-induced allergic conjunctivitis, and the data show that conjunctival CD4+ T cells expressing ST2 may play an important role in IL-5 secretion, recruiting eosinophils into conjunctiva on ocular allergen challenge.

Thyroid-Associated Orbitopathy*

Thyroid-associated orbitopathy (TAO) is usually diagnosed clinically. Early presentation of TAO such as ocular irritation, lid puffiness, and mild retraction may be overlooked and misdiagnosed. Careful clinical evaluation, laboratory investigations, and orbital imaging studies are needed for diagnosing early TAO. Knowing the pathogenesis will open the door for obtaining directed and effective treatment for the inflammatory process in TAO. Most patients with mild to moderate active TAO are treated with observation alone as the available treatment modalities effective in controlling the disease have many potential side effects. Severe active TAO, compressive optic neuropathy, and severe exposure keratopathy are the main indications for treatment with immunosuppressant agents, orbital radiotherapy, or orbital decompression. Surgery remains the final rehabilitation in TAO, which should be done during cicatricial (inactive) TAO when reliable and stable results can be obtained.
The effects of intracochlear cyanide and tetrodotoxin on the properties of single cochlear nerve fibres in the cat.

1. Tuning properties and spontaneous discharge rate of single cochlear fibres in the anaesthetized cat were determined under conditions where millimolar concentrations of KCN were instilled into the scala tympani. 2. Short‐term effects on the tuning properties were obtained, in which the threshold of the low threshold sharply tuned tip segment of the frequency‐threshold ('tuning') curve (f.t.c.) was elevated by up to 40 db, without changes in the threshold of the low frequency ‘tail’ segment of the f.t. c. , or necessarily changes in the spontaneous and maximally evoked activity. These changes were accompanied by a shift of the characteristic frequency tip segment towards lower frequencies. All these effects could be reversed. 3. The long‐term effects of repeated KCN instillations produced irreversible changes similar to the short‐term effects. 4. These changes correlated well with depression of the amplitude of the gross cochlear action potential but not with the cochlear microphonic potential, both recorded at the round window. 5. Instillations of tetrodotoxin (TTX) rapidly reduced and blocked the cochlear fibre discharges without effects on their tuning, in contrast to the effects of KCN.
Design and performance of an OFDM-CPM receiver for wireless communications

A new class of orthogonal frequency division multiplexing-continuous phase modulation (OFDM-CPM) signals has been introduced recently that outperforms conventional OFDM-PSK signals. These signals employ multi symbol observations for detection of data. An optimum OFDM-CPM receiver was designed that observed n symbols of the received waveform, and arrived at an optimum estimate of the data transmitted in the first symbol interval. However, from the viewpoint of receiver complexity, this receiver is quite complex and the complexity grows exponentially as a function of number of observation symbols. Thus, in this paper, we develop and investigate a less complex OFDM-CPM receiver that employs post-FFT signal processing for recovery of data. Performance of this receiver is evaluated over multipath fading channels for several subclasses of OFDM-CPM signals. It is shown that we achieve error rate performance that is far superior to the performance offered by conventional OFDM-PSK systems
A 24-GHz highly integrated transceiver in 0.5-µm E/D-PHEMT process for FMCW automotive radar applications

This paper describes a 24-GHz highly integrated transceiver in 0.5-µm E/D-PHEMT process for frequency-modulation continuous-wave (FMCW) automotive radar applications. The transceiver includes a voltage controlled oscillator (VCO), a power amplifier (PA), a buffer amplifier (BA), a low noise amplifier (LNA), and a down converter mixer. The transmitter delivers a RF output power of 13 dBm with a dc supply voltage of 5 V. The conversion gain and noise figure of the receiver are better than 9 and 8.7 dB, respectively. The chip size of the transceiver is 3×2 mm2.
Pretreatment Prognostic Factors Influencing Distant Metastasis-Free Survival in Locally Advanced Squamous Cell Carcinoma of the Head and Neck Treated With Radiation Therapy With or Without Concurrent Chemotherapy

Purpose:To investigate impact of various pretreatment prognostic factors influencing distant metastasis-free survival (DMFS), in patients with locally advanced (stage III/IV), nonmetastatic squamous cell carcinoma of the head and neck. Material and Methods:During 2 consecutive prospective randomized trials, a total of 289 patients were treated with standard fraction (conventionally fractionated [CF]) or hyperfractionated radiation therapy with or without concurrent low-dose daily platinum chemotherapy (CHT). Results:Kaplan-Meier analysis showed that gender (P = 0.96) and age (P = 0.88) did not influence DMFS, similarly to Karnofsky Performance Status (KPS) (P = 0.55), T stage (P = 0.12), and primary tumor location (P = 0.94). N stage (P = 0.0274), stage grouping (P = 0.0016), treatment (P = 0.0008), and concurrent CHT (P = 0.0001) influenced DMFS. Univariate Cox analysis showed that treatment lost its significance, whereas N staging became marginally insignificant (P = 0.061). Multivariate Cox analysis showed that only lower stage grouping (P = 0.014) and the addition of concurrent CHT (P < 0.001) were independent prognosticator of improved DMFS. Conclusion:This analysis showed that only stage grouping and concurrent CHT predicted DMFS in patients with locally advanced squamous cell carcinoma of the head and neck treated with RT with and without concurrent low-dose daily CHT. These results may have implication for future studies in this disease.
Low dropout regulator with temperature coefficient curvature correction topology

The LDO Voltage Regulator circuit with temperature coefficient curvature correction topology is proposed in this paper. The LDO consists of a start-up circuit, a bias generator, a three-stage error amplifier, a power MOSFET, and a temperature coefficient curvature correction circuit. The circuit is simulated with 0. 18μm CMOS Technology. The supply voltage can be as low as 800mV with the output voltage of 664mV. The proposed circuit obtains the temperature coefficient as low as 23.7ppm/°C for supply voltage ranging from 800mV until 1.5V. The lowest temperature coefficient of 6.1ppm/°C is obtained at 1.1V supply voltage. The temperature coefficient is measured for a wide range of temperature ranging from −50°C to 130°C. The stability is ensured from the simulation with high low-frequency open loop gain of above 105dB and high phase margin of above 100°.
