Sensorless vector control of IPMSM with DC link current measurement at low speeds
Authors: Kubota Hisao , Nakagawa Satoshi , Kobayashi Takayuki
Published: June 2010

This paper presents a method of estimating pole position of interior permanent magnet synchronous motors (IPMSMs). The proposed method estimates the pole position at low speeds and standstill by measuring only the DC link current of the inverter. The pole position is estimated by using the saliency of the IPMSMs. In order to detect the saliency, three‐phase triangular carrier waves are used. The DC link current is measured at the tops and bottoms of the carrier waves. Experimentation is performed to confirm the validity of the proposed method. © 2010 Wiley Periodicals, Inc.

Authors: Itoh Yasuyuki , Kobayashi Takenori
Published: June 2010

This paper presents a single‐factor model to describe the fluctuation of the electricity futures price for its trading risk management. An autoregressive moving‐average model [ARMA (2,1) process] was used to express the stochastic process of the price, instead of a conventionally used Markov process such as the AR(I) process, where the ARMA(2, 1) process becomes a hybrid of short‐ and long‐term mean‐reversion processes in the continuous time model. This model was applied to the analysis of the price of electricity futures (the PJM Monthly) traded on the New York Mercantile Exchange (NYMEX). The results showed that the model well explained the term structure of the volatility of futures price with respect to the time to maturity, which is important for estimating its trading risk. The expected long‐term fixed electricity price and its confidence interval were also estimated by using the obtained model function of the forward curve and its parameters. © 2010 Wiley Periodicals, Inc.

Consideration of Particle Swarm Optimization combined with tabu search
Authors: Nakano Shinichi , Ishigame Atsushi , Yasuda Keiichiro
Published: June 2010

This paper presents a new form of Particle Swarm Optimization (PSO) based on the concept of tabu search (TS). In PSO, when a particle finds a local optimal solution, all of the particles gather around that one, and cannot escape from it. On the other hand, TS can escape from the local optimal solution by moving away from the best present solution. The proposed Tabu List PSO (TL‐PSO) is a method for combining the strong points of PSO and TS. This method stores the history ofpbestin a tabu list. When a particle has a reduced searching ability, it selects apbestof the past from the historical values, which is used for the update. This makes each particle active, and the searching ability of the swarm makes progress. The proposed method was validated by numerical simulations with several functions that are well known as optimization benchmark problems for comparison to the conventional PSO method. © 2010 Wiley Periodicals, Inc.

Development of an Electrochemical Immunoassay Based on the Use of an Eight‐Electrodes Screen‐Printed Array Coupled with Magnetic Beads for the Detection of Antimicrobial Sulfonamides in Honey
Authors: Centi S. , Stoica A. I. , Laschi S. , Mascini M.
Published: June 2010

In this work an electrochemical immunoassay, based on a direct competitive assay, was developed using magnetic beads as solid phase and carbon screen‐printed arrays as transducers for the detection of sulfonamides in food matrices such as honey. Magnetic beads coated with protein A were modified by immobilisation of specific antibodies and then the competition between the target analyte and the corresponding analyte‐labelled with an enzyme was carried out; after the immunosensing step, beads were captured by a magnet onto the working surfaces of a screen‐printed eight‐electrodes array for a multiple electrochemical detection. Screen‐printed eight‐electrodes arrays were chosen as transducers due to the possibility to repeat multiple analysis and to test different samples simultaneously. Alkaline Phosphatase (AP) was used as enzyme label and Differential Pulse Voltammetry (DPV) as fast electrochemical technique. Calibration curves demonstrate that the developed electrochemical immunoassay was able to detect this class of drugs in standard solutions at low concentrations (ng/mL levels). The short incubation times (25 min) and the fast electrochemical measurement (10 sec) make of these systems a possible alternative to classic ELISA tests.

Tissue adhesives are a valuable alternative for mechanical tissue fixation by sutures or staples. Adhesives are desirable in body regions where damage and bleeding must be avoided. Tissue adhesives provide easy and fast handling. This study reports the development of a tissue adhesive based on 1,2‐ethylene glycol bis(dilactic acid) (ELA) functionalized with hexamethylene diisocyanate (HDI) to produce isocyanate terminated ELA‐NCO which was characterized by NMR and FTIR spectroscopy. ELA‐NCO together with chain elongation agents forms an adhesive system suitable for tissue fixation. Several biodegradable polymers, such as hyaluronic acid, gelatin, chitosan acetate, and chitosan chloride were tested as chain elongation agents to obtain an adhesive system and studied on bovine muscle tissue to evaluate their adhesive strength and compared to fibrin glue. Tensile strength of glued joints was determined by a Zwick universal testing machine at ambient temperature. Mixtures of ELA‐NCO and chitosan acetate or chloride, showed significantly higher adhesive strength than fibrin glue. Reaction between ELA‐NCO and chitosan chloride produced polyurethane was traced by FTIR spectroscopy. NMR, FTIR, and rheological measurements demonstrated that ELA‐NCO and chitosan chloride can be sterilized by γ‐rays or superheated water vapor without alterations, respectively. A mixture of ELA‐NCO and chitosan chloride can be useful as medical tissue adhesive. © 2010 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2010.
A spatial regression analysis of the influence of topography on monthly rainfall in East Africa
Authors: Hession S. L. , Moore N.
Published: June 2010

Precipitation in Kenya is highly variable and dominated by a variety of physical processes. Statistical studies of climate patterns have historically focused on application of ordinary least squares (OLS) regression to test hypotheses related to multiple predictive variables, perhaps in an attempt to better understand the physical mechanisms that drive precipitation, or on use of spatially explicit models, typically kriging‐ or spline‐based analyses, for the purpose of improving predictions. Each of these approaches may be individually useful; however, they all possess limitations. OLS approaches have yielded biased results in the presence of spatially autocorrelated data. Kriging‐ and spline‐based studies often focus on providing improved predictions rather than understanding. Here we use spatial regression, a method not commonly used in analysis of climate data, to assess the role of predictive variables while explicitly incorporating spatial autocorrelation in parameter estimation and hypothesis testing. This approach can yield a better understanding of relationships between precipitation and multiple predictive variables with improved statistical rigour. Using spatial regression, we show that topographic variables such as elevation and slope strongly influence rainfall during the ‘long rains’ and ‘short rains’, which are vital for Kenyan agriculture. Outside these seasons, we find that smaller (mesoscale) variations in elevation are statistically significant. Further, we demonstrate the shortcomings of automated selection procedures such as stepwise regression through the identification of spurious results due to confounding.

Investigating muddy floods in Slovakia
Authors: Stankoviansky M. , Minár J. , Barka I. , Bonk R. , Trizna M.
Published: June 2010

The problem of land degradation by muddy floods in Slovakia arose because of land use changes in the second half of the 20th century, accompanied more recently with climate change. This paper presents empirical research as well as modelling of the spatial distribution of muddy floods in Slovakia. Natural conditions, land cover and recorded events from the last few decades are described and analysed. Special attention is paid to the region of the Myjava Hill Land where systematic observation of muddy floods has been undertaken for some time. A model assessing muddy flood hazard throughout Slovakia is presented. It is based on comparison of models of actual soil erosion and the potential for local flooding. The results accord with preliminary empiric investigations. More detailed and systematic research of these phenomena is important for environmental planning and impacts upon insurance decisions.

Synthesis and characterization of epoxy with improved thermal remendability based on Diels‐Alder reaction
Authors: Tian Qiao , Rong Min Zhi , Zhang Ming Qiu , Yuan Yan Chao
Published: June 2010

To produce an epoxy resin with high intrinsic self‐healing efficiency, furfurylglycidyl ether (FGE) was synthesized following a two‐step route. It carried one furan and one epoxide on each of its molecules. Having been cured using N,N′‐(4,4′‐diphenylmethane)bismaleimide and methylhexahydrophthalic anhydride, FGE was then polymerized with two types of intermonomer linkages. That is, thermally reversible Diels–Alder (DA) bonds from the reaction between furan and maleimide groups, and thermally irreversible bonds from the reaction between epoxide and anhydride groups. These two types of bonds provide the polymer with thermal remendability and load‐bearing capacity, respectively. Compared with N,N‐diglycidylfurfurylamine, which was previously developed by the authors and has a similar structure to FGE but with fewer furan rings, FGE can react with maleimide with lower activation energy and the DA bonds formed exhibit higher reversibility. Consequently, improved crack healability of the cured FGE characterized by nearly full recovery of fracture toughness was revealed using double cleavage drilled compression tests.

1H NMR‐based kinetic and mechanistic study of unusual skeletal rearrangements of a spirobornyl tosylate derivative
Authors: Lobb Kevin A. , Kaye Perry T.
Published: June 2010

1H NMR analysis of the kinetics of skeletal rearrangement of optically pure 3,3‐xylyl‐2‐exo‐bornyl tosylate in CDCl3 indicates the operation of tandem autocatalytic and pseudo‐first‐order transformations, leading sequentially to a pair of isomeric camphene derivatives and involving partial racemization. Changing the solvent system has been shown to permit the chemoselective isolation of either of the isomeric camphenes. Copyright © 2010 John Wiley & Sons, Ltd.
Crystal structure and kinetic mechanism of aminoglycoside phosphotransferase‐2″‐IVa
Authors: Toth Marta , Frase Hilary , Antunes Nuno Tiago , Smith Clyde A. , Vakulenko Sergei B.
Published: June 2010

Acquired resistance to aminoglycoside antibiotics primarily results from deactivation by three families of aminoglycoside‐modifying enzymes. Here, we report the kinetic mechanism and structure of the aminoglycoside phosphotransferase 2″‐IVa (APH(2″)‐IVa), an enzyme responsible for resistance to aminoglycoside antibiotics in clinical enterococcal and staphylococcal isolates. The enzyme operates via a Bi‐Bi sequential mechanism in which the two substrates (ATP or GTP and an aminoglycoside) bind in a random manner. The APH(2″)‐IVa enzyme phosphorylates various 4,6‐disubstituted aminoglycoside antibiotics with catalytic efficiencies (kcat/Km) of 1.5 × 103 to 1.2 × 106 (M−1 s−1). The enzyme uses both ATP and GTP as the phosphate source, an extremely rare occurrence in the phosphotransferase and protein kinase enzymes. Based on an analysis of the APH(2″)‐IVa structure, two overlapping binding templates specifically tuned for hydrogen bonding to either ATP or GTP have been identified and described. A detailed understanding of the structure and mechanism of the GTP‐utilizing phosphotransferases is crucial for the development of either novel aminoglycosides or, more importantly, GTP‐based enzyme inhibitors which would not be expected to interfere with crucial ATP‐dependent enzymes.

Raytheon Visions Systems (RVS) is furthering its capability to deliver state‐of‐the‐art high performance large format HgCdTe focal plane arrays (FPAs) for dual‐band long‐wavelength infrared (LWIR) detection. Missile seekers are designed to acquire targets of interest at long ranges and discriminate targets from clutter. The use of dual‐band long wavelength infrared detector technology provides the ability for these seekers to combine these operations into the same package with enhanced performance. Increasing the format size of dual‐band long‐wavelength FPAs and tailoring the detector design for specific long‐wavelength bands enables seekers to be designed for increased field‐of‐view, longer target acquisition ranges, and improved accuracy. This paper will review in further detail the aspects of detector design, MBE wafer growth, wafer fabrication, and detector characterization that are contributing to development and demonstration of high performance large format dual‐band LWIR FPAs at RVS.

Robotic devices for water main in‐pipe inspection: A survey
Authors: Mirats Tur Josep M. , Garthwaite William
Published: June 2010

Many water companies have a limited knowledge of the structural condition of their assets. Underground assets have been installed for a long time, so they are old and are failing, leading to leaks, breaks, and consequential damage to third parties. A common practice is the removal of pipe sections for condition assessment, causing service interruption and resulting in the assessment of a small percentage of the network as well as high replacement costs. Systematic condition assessment of pipes could help to prevent network problems as well as in proposing an efficient investment plan. This can be performed by using robotic inspection devices. Toward this end, this paper reviews existing robotic tools and analyzes open problems to be addressed for a successful robotic inspection device. © 2010 Wiley Periodicals, Inc.
