Off-line Model Predictive Control of DC-DC Converter (2010)

In this paper, a novel control method for the dc-dc converter has been proposed. The dcdc converter has been modeled as a mixed logical dynamical (MLD) system since it has the ability to combine continuous and discrete properties. For the control, a model predictive control (MPC) based method has been introduced. The optimization problem has been solved as a multi-parametric off-line programming problem. The result has been obtained as the state space partition which makes the implementation feasible. As a result, computation time is shortened without deteriorating control performance. Finally, it has been demonstrated that the output voltage has been tracked to the reference at the expense of tracking performance by introducing the term to reduce the switching in the cost function. In some cases, other factors such as resistance loss in rl shown in Fig. 1 may need to be considered, although the cost function given by Eq. (28) considers only the tracking performance and switching loss. Note, however, that the factors represented as linear and/or quadratic forms of the state variable can be incorporated into the cost function. Further research includes robustness analysis in implementation and investigation of performance for different cost functions as mentioned above.
On-line identification of depurinating DNA adducts in human urine by capillary electrophoresis — fluorescence line narrowing spectroscopy (2000)

The benzo[a]pyrene (BP)-derived 7-(benzo[a]pyren-6-yl)guanine (BP-6-N7Gua) depurinating one-electron oxidation adduct was identified in the urine extracts of coal-smoke-exposed humans for the first time. Urine samples were prepared by solid-phase extraction and reversed-phase high-performance liquid chromatography. Subsequently, the BP-6-N7Gua adduct was identified on-line with capillary electrophoresis - fluorescence line narrowing spectroscopy (CE-FLNS) at 4.2 K. The daily excretion of BP-6-N7Gua in human urine of individuals exposed to coal smoke was approximately 226 pmol per μmol of creatinine. Due to the high level of excretion we propose that BP-6-N7Gua adducts found in urine could serve as effective biomarkers for risk assessment of BP exposure. The results demonstrate that CE-FLNS allows for on-line separation and DNA adducts identification in complex fluid extracts.
Clinical features, biochemistry, and <i>HLA</i> ‐ <i>DRB1</i> status in youth‐onset type 1 diabetes in Mali (2022)

C-peptide values were higher than expected in those diagnosed as T1D and autoantibody rates lower than in European populations. It is quite possible that some cases have an atypical form of T1D, ketosis-prone T2D, or youth-onset T2D. This study will help guide assessment and individual management of Malian diabetes cases, potentially enabling healthier outcomes.
Hybrid solving technique for vehicle planning with communication constraints (2012)

The complexity of modern engagements and the numerous communication links made available increase the difficulties of mission planning and execution. In particular, finding unit waypoints while meeting frequencies allocation is a hard operational problem. Continuity of communications among the command chain must be guaranteed on the move in spite of tactical mobility, networks availability, path loss, jamming, mission updates and versatile threats. In previous works, we proposed a problem formulation relying on vehicle plan optimization, that satisfies network connectivity and operational constraints. This paper adress hybrid search techniques to solve Bandwidth-constrained Vehicle Planning (BVP) on-line problem instances. It is modeled using constraint-based formulations to express both network connectivity and operational requirements (missions, waypoints, terrain). Vehicle planning is then solved and optimized according to a combination of a metaheuristic, namely an Ant Colony Optimisation (ACO), and Constraint Programming (CP) techniques. Various forms of optimization strategies are compared and evaluated on realistic scenarios, outperforming previous results.
<scp>IP</scp>Telephony (2003)

Abstract IP telephony networks have emerged as an alternative to the public switched telephone network (PSTN) for providing voice and video transport services. IP telephony systems are designed to transmit packetized voice using the Internet Protocol (IP), allowing providers the ability to bypass the PSTN and offer advanced intelligent network (AIN) services. In this article we present a detailed survey of various issues in IP telephony networks. We discuss how open protocols and architectural entities are designed, as well as how they are used in common deployment scenarios. We outline several issues of packet audio over IP networks and show how the efficient design of IP telephony network elements can significantly improve the received audio quality. IP networks may require advanced resource management and pricing strategies to offer superior quality of service (QoS) under conditions of high demand. We conclude this article with a discussion of security and regulatory issues in IP telephony networks.
P469Experimental evidence of ventricular arrhythmias susceptibility in different animal models (2017)

AVCB(AVCB-I,-II,-III), atrial fibrillation(AF), SVT(all except AF), VT and ventricular fibrillation(VF). Results: SND, SVT, AF, VT, VF and AVCB emerged most often de novo postoperative and frequently developed decades after surgery. Coexistence of multiple arrhythmias was present in 60 patients(36%), including SND, SVT and AF(N37, 22%), VT and VF(N4, 2%) or both atrial and ventricular arrhythmias(N19, 12%). SVT and AF or VT and VF coexisted in respectively 20(13%) and 5 patients(3%). SND and SVT or AF occurred in 34 patients(20%). SND preceded or followed SVT/AF in respectively 17(10%) and 13 patients(8%); in 4 patients(2%) they occurred approximately simultaneously. Ventricular tachyarrhythmias(N23) were most often preceded by atrial arrhythmias(N17, 74%).
Chain transfer to polymer in emulsion copolymerizations (2001)

Chain transfer to polymer in emulsion copolymerizations of (i) vinyl acetate (VAc) with n-butyl acrylate (BA) and (ii) BA/acrylic acid with (a) methyl methacrylate (MMA) and (b) styrene (S) has been studied using 13C NMR spectroscopy to quantify the level of branching in the copolymers produced. The results reveal synergistic effects in which the inclusion of a small amount of comonomer leads to disproportionate changes in the level of branching. The data from the VAc/BA copolymerizations show that radicals with VAc end units abstract hydrogen atoms from BA repeat units more frequently than from VAc repeat units and that radicals with VAc end units are more effective in abstracting hydrogen atoms from BA repeat units than are radicals with BA end units. These effects lead to higher levels of branching in VAc/BA copolymers than results from the corresponding homopolymerizations and are a consequence of the efficacy of hydrogen abstraction at BA backbone tertiary C-H bonds by the highly-reactive VAc-ended chain radicals. In contrast, the effect of introducing MMA or S to an acrylate polymerization is to disproportionately reduce the level of branching, with S being more effective than MMA in moderating chain transfer to polymer. These effects arise because propagating radicals with MMA or S end-groups have longer lifetimes compared to those with acrylate end groups and have a very much lower tendency to abstract hydrogen atoms from acrylate repeat units.
Network-coded cooperative extension of link level FEC in DVB-SH (2011)

In this paper we propose a cooperative ad-hoc networking approach which leverages on network coding (NC) for enhancing coverage in Digital Video Broadcasting - Satellite Handheld (DVB-SH) systems. Our numerical results, based on physical layer abstraction, show that a cooperative relaying system based on network coding can bring important benefits in terms of both throughput and coverage with respect to a system in which nodes receive from satellite only, as well as with respect to a system in which nodes cooperate through a simple relaying scheme.
[Application of isolated canine teeth and single implant supported telescopic overdenture in a case with defective dentition of maxillary]. (2012)

A patient with defective dentition in the upper jaw was placed with implant in left upper jaw. Telescopic overdenture was fabricated and supported by the implant and canine tooth in right upper jaw. The patient felt very comfortable, and this type of restoration could provide sufficient stability and maintain tooth and peri-implant tissues healthy. The preliminary clincal results of this restoration show that isolated canine tooth and single implant supported telescopic overdenture are feasible.
Oxidation kinetics of YBaCo <sub>4</sub> O <sub> 7+ <i>δ</i> </sub> and substituted oxygen carriers (2018)

In this paper, the relaxation kinetics of the oxidation process of the YBaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> , Y<sub>0.95</sub>Ti<sub>0.05</sub>BaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> and Y<sub>0.5</sub>Dy<sub>0.5</sub>BaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> oxygen carriers is studied with isothermal reaction data. XRD analysis for fresh samples shows that all the samples have YBaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> structure. Scanning electron microscopy images of samples show that the samples consist of porous agglomerates of primary particles. Isothermal TG experiments are conducted with temperatures of 290°C, 310°C, 330°C and 350°C, respectively. It is found that the Avrami-Eroféev model describes solid-phase changes in the oxygen absorption process adequately. The results show that the distributed activation energies of the oxidation process obtained by the Avrami-Eroféev model are 42.079 kJ mol<sup>-1</sup>, 42.944 kJ mol<sup>-1</sup> and 41.711 kJ mol<sup>-1</sup> for the YBaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> , Y<sub>0.95</sub>Ti<sub>0.05</sub>BaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> and Y<sub>0.5</sub>Dy<sub>0.5</sub>BaCo<sub>4</sub>O<sub>7+<i>δ</i></sub> oxygen carriers, respectively. The kinetic model was obtained to predict the oxygen carrier conversion of oxygen absorption for different time durations. The kinetic parameters obtained here are quite vital when this material is used in reactors.
11th OOPSLA workshop on behavioral semantics (2002)

The goal of this workshop is to foster precise and explicit OO specifications of business and system semantics, independently of any (possible) realization. As a result of lip service to these ideas, the systems we build or buy are all too often not what they are supposed to be. Doing better than that requires both a clear understanding of the semantics of the problems together with their business and technological environments, and abstract, precise and explicit specifications of that semantics. The specific theme this year is on serving the customer.
Chemoenzymatic construction of a four-component Ugi combinatorial library (2000)

The chemoenzymatic preparation of a nine-member Ugi condensation library is described. The carboxylic acid and amine precursors are based on 3-hydroxybutyrate and 4-amino-1-butanol, respectively, and have been acylated selectively using a variety of acyl donors catalyzed by porcine pancreatic lipase. The enzyme is selective for the hydroxyl functionalities on both precursors, thereby yielding 3-acyl-butyric acid and 4-amino-1-acyl compounds. These enzymatically generated derivatives were then subjected to a four-component Ugi condensation reaction in the presence of acetaldehyde and methyl isocyanoacetate. Isolated yields of the alpha-(acylamino)amide Ugi products ranged from 72-95%. The inherent chemoselectivity of enzymatic catalysis may play an increasingly important role in expanding the structural diversity that can be achieved by chemical multicomponent condensation reactions.
Computational Characterization of Zr-Oxide MOFs for Adsorption Applications (2022)

Zr-oxide secondary building units construct metal-organic framework (MOF) materials with excellent gas adsorption properties and high mechanical, thermal, and chemical stability. These attributes have led Zr-oxide MOFs to be well-recognized for a wide range of applications, including gas storage and separation, catalysis, as well as healthcare domain. Here, we report structure search methods within the Cambridge Structural Database (CSD) to create a curated subset of 102 Zr-oxide MOFs synthesized to date, bringing a unique record for all researchers working in this area. For the identified structures, we manually corrected the proton topology of hydroxyl and water molecules on the Zr-oxide nodes and characterized their textural properties, Brunauer-Emmett-Teller (BET) area, and topology. Importantly, we performed systematic periodic density functional theory (DFT) calculations comparing 25 different combinations of basis sets and functionals to calculate framework partial atomic charges for use in gas adsorption simulations. Through experimental verification of CO<sub>2</sub> adsorption in selected Zr-oxide MOFs, we demonstrate the sensitivity of CO<sub>2</sub> adsorption predictions at the Henry's regime to the choice of the DFT method for partial charge calculations. We characterized Zr-MOFs for their CO<sub>2</sub> adsorption performance via high-throughput grand canonical Monte Carlo (GCMC) simulations and revealed how the chemistry of the Zr-oxide node could have a significant impact on CO<sub>2</sub> uptake predictions. We found that the maximum CO<sub>2</sub> uptake is obtained for structures with the heat of adsorption values >25 kJ/mol and the largest cavity diameters of ca. 6-7 Å. Finally, we introduced augmented reality (AR) visualizations as a means to bring adsorption phenomena alive in porous adsorbents and to dynamically explore gas adsorption sites in MOFs.
Chiroptical Properties of Cholesteric Liquid Crystals Induced by Chiral Photochromic 3,3′-Dialkoxyazobenzenes (2001)

Abstract The spectroscopic features and photoisomerization behaviors of chiral photochromic 3,3′-dialkoxyazobenzenes were evaluated in an isotropic solution and a nematic solvent. The effect of photoisomerization on the helical twisting power and handedness of these chiral dopants in induced cholesteric liquid crystals were studied. Depending on the distance of the chiral center from the azo-core, elongation of the helical pitch and reversion of the handedness upon E-to-Z photoisomerization were observed. These characteristics are interesting for optical devices based on light-controlled phase switching.
Glycoconjugate vaccines: current approaches towards faster vaccine design (2019)

<b>Introduction</b>: Over the last decades, glycoconjugate vaccines have been proven to be a successful strategy to prevent infectious diseases. Many diseases remain to be controlled, especially in developing countries, and emerging antibiotic-resistant bacteria present an alarming public-health threat. The increasing complexity of future vaccines, and the need to accelerate development processes have triggered the development of faster approaches to glycoconjugate vaccines design. <b>Areas covered</b>: This review provides an overview of recent progress in glycoconjugation technologies toward faster vaccine design. <b>Expert opinion</b>: Among the different emerging approaches, glycoengineering has the potential to combine glycan assembly and conjugation to carrier systems (such as proteins or outer membrane vesicles) in one step, resulting in a simplified manufacturing process and fewer analytical controls. Chemical and enzymatic strategies, and their automation can facilitate glycoepitope identification for vaccine design. Other approaches, such as the liposomal encapsulation of polysaccharides, potentially enable fast and easy combination of numerous antigens in the same formulation. Additional progress is envisaged in the near future, and some of these systems still need to be further validated in humans. In parallel, new strategies are needed to accelerate the vaccine development process, including the associated clinical trials, up to vaccine release onto the market.

Exploiting Wikipedia for Information Retrieval Tasks (2015)

Wikipedia - the online encyclopedia - has long been used as a source of information for researchers, as well as being a subject of research itself. Wikipedia has been shown to be effective in recommender systems, sentiment analysis, validation and multiple domains in information retrieval. One of the reasons for Wikipedia's popularity among researchers and practitioners is the multiple types of information it contains, which enables practitioners to select the right "tool" for their respective tasks. In addition to its great potential, this multitude of information sources also poses a challenge: which sources of information are best suited for a specific problem and how can different types of data be combined? This tutorial aims to provide a holistic view of Wikipedia's different features - text, links, categories, page views, editing history etc. - and explore the different ways they can be utilized in a machine learning framework. By presenting and contrasting the latest works that utilize Wikipedia in multiple domains, this tutorial aims to increase the awareness among researchers and practitioners in these fields to the benefits of utilizing Wikipedia in their respective domains, in particular to the use of multiple sources of information simultaneously.

Fully embedded myoelectric control for a wearable robotic hand orthosis (2017)

To prevent learned non-use of the affected hand in chronic stroke survivors, rehabilitative training should be continued after discharge from the hospital. Robotic hand orthoses are a promising approach for home rehabilitation. When combined with intuitive control based on electromyography, the therapy outcome can be improved. However, such systems often require extensive cabling, experience in electrode placement and connection to external computers. This paper presents the framework for a stand-alone, fully wearable and real-time myoelectric intention detection system based on the Myo armband. The hard and software for real-time gesture classification were developed and combined with a routine to train and customize the classifier, leading to a unique ease of use. The system including training of the classifier can be set up within less than one minute. Results demonstrated that: (1) the proposed algorithm can classify five gestures with an accuracy of 98%, (2) the final system can online classify three gestures with an accuracy of 94.3% and, in a preliminary test, (3) classify three gestures from data acquired from mildly to severely impaired stroke survivors with an accuracy of over 78.8%. These results highlight the potential of the presented system for electromyography-based intention detection for stroke survivors and, with the integration of the system into a robotic hand orthosis, the potential for a wearable platform for all day robot-assisted home rehabilitation.

Analysis on Learning Effects of the Education Program Applying the Team-based Learning Method for Building Construction (2017)

본 연구는 건축공학교육에의 팀 기반 학습의 도입 효과를 정량적으로 분석하고자 하였다. 이를 위하여 국내의 건축공학교육의 특성을 고려하여 팀 기반 학습 교육 프로그램을 수정, 제안하고, 제안된 팀 기반 학습을 건축시공학 수업에 적용하였다. 제안된 팀 기반 학습 강의는 준비단계, 학습준비도 확인단계, 활용단계로 구성되었다. 수강생들을 대상으로 설문을 수행함으로써 수강생들의 학습효과와 만족도를 분석하였다. 분석결과, 팀 기반 학습 강의의 학습효과와 만족도가 이론식 강의보다 높았다. 학습준비도 확인단계의 학습준비도 확인시험의 학습효과와 만족도가 가장 높았고, 활용단계의 평가에 대한 학습효과와 만족도는 낮았다. This study aims to quantitatively analyze impacts of the team-based learning (TBL) method on learning of architectural engineering students. A TBL-based education program, consisted of preparation, readiness assurance, and application phases, was proposed by considering characteristics of architectural engineering education in South Korea and was applied in building construction classes. In order to measure learning effects and satisfaction levels of the proposed TBL-based education program, a set of questionnaires was conducted with students who took the building construction classes. As the results, learning effects and satisfaction levels of the TBL-based approach were higher than those of traditional approaches. Individual and team readiness assurance tests in the readiness assurance phase were the most effective and satisfactory items, while assessment in the application phase was the least effective and satisfactory item.
