Seawater based cold plate for power electronics

Cooling for power electronics in leisure vessels has so far been based in the use of forced air, even though such vessels are surrounded by water which can ultimately be used to dump the heat developed by power electronics converters and electrical machines. Some of the reasons to avoid the use of sea water for cooling are the need to deal with biological-fouling, salt water, corrosion, and condensation. We propose to apply a new concept where pre-filtered seawater is used to cool down power electronic modules in order to significantly reduce the size of the cooling system. A new type of cold plate with direct flow of seawater has been designed considering the mentioned challenges. The cold plate will cool down a 5kW (10kW peak) power electronics module. Such module consists of a 3 kW 3-phase AC-DC rectifier, a 2 kW (10kW peak) full-bridge DC-DC converter and a 5 kW (10 kW peak) DC-AC single phase inverter.
Absent Fetal Movement Response with a Blunted Cardioacceleratory Fetal Response to External Vibratory Acoustic Stimulation in a Fetus with the Pena-Shokeir Syndrome (Fetal Akinesia and Hypokinesia Sequence)

We present a case that describes a partial fetal response to external vibratory acoustic stimulation in that, although no fetal movements were elicited, a blunted, brief positive cardioacceleratory response was noted. This fetus exhibited features of the Pena-Shokeir syndrome, characterized by skeletal neurogenic atrophy, yet with a normal auditory system at autopsy. This observation may suggest that the prolonged increase in the basal fetal heart noted after fetal vibratory acoustic stimulation is sustained by active fetal movements, absent in this fetus due to joint contractures.
Ferromagnetic GaMnP Prepared by Ion Implantation and Pulsed Laser Annealing

We present the magnetic, transport, and structural properties of GaMnP with different Mn concentrations prepared by ion implantation and pulsed laser annealing. The Curie temperature increases with Mn concentration and the samples show in-plane magnetic anisotropy due to the in-plane compressive strain in the GaMnP layer. Anomalous Hall effect and negative magnetoresistance are observed, indicating the carrier mediated nature of the ferromagnetism in GaMnP. According to the micro-Raman spectroscopy data after pulsed laser annealing, the implanted layer has been fully recrystallized and the carrier concentration (hole) increases with Mn concentration.
Application of an Angular Exposure System to fabricate true-chip-size packages for SAW devices

Surface Acoustic Wave (SAW) filters are key components of mobile phones. In SAW components mechanical waves propagate on the surface of the chip, so the package must provide a cavity. Solid materials on the chip would inhibit the propagation of the surface waves. Reduction of size and cost, improved reliability and electrical performance are the main trends of SAW component evolution. Therefore, advanced cavity package technologies are required for SAW components. The Die Size SAW Package (DSSP) developed by EPCOS is a true chip size wafer level package that meets these requirements. The cavity package of the DSSP causes a significant topography. As a consequence the following rerouting process has to deal with the photolithographical challenge in terms of conformal resist coating and resist exposure. While conformal coating can be achieved by a spray process the exposure of patterns at sidewalls of topographic structures needs a customized solution. Exposure at a selectable angle instead of standard perpendicular exposure will be discussed in this paper based on EPCOS' DSSP technology.
Processes Scheduling on Heterogeneous Multi-core Architecture with Hardware Support

Heterogeneous Chip Multi-Processors (heter-CMP) provide suitable resources to various applications and could get more benefits on performance than homogeneous CMP. To fully develop the performance of the heter-CMP system, the applications should be scheduled to the proper cores by the scheduler of the operating system according to their behaviours. Besides, the last level cache (LLC) miss rate is often used as the metric to identify the application features. However, the LLC miss rate could not reflect the application behaviours accurately since the memory access delay, the most important application character is related to patterns of the memory access and many other issues. To improve the accuracy of scheduling on the heter-CMP system, this paper supplies performance counters for the LLC miss penalty to monitor application behaviours. Based on that, the latency-aware scheduling algorithm for asymmetry chip multi-processors (LA-ACMP) is proposed and implemented. Those hardware supports are implemented on the Godson-3 multi-core RTL and simulator and the LA-ACMP algorithm is integrated to the Linux kernel. The performance evaluation on those platforms shows that the LA-ACMP algorithm with LLC miss penalty outperforms the algorithm with LLC miss rate about 32.4%, and outperforms the original schedule algorithm about 18.4%.
Outage capacity for MIMO-OFDM systems in block fading channels

We introduce the concept of outage capacity for multiple-input multiple-output (MIMO)-orthogonal frequency-division multiplexing (OFDM) systems in time and frequency block fading channels. We derive the outage capacity and its expression is shown to be related to the characteristic function of the capacity for the usual quasi-static MIMO fading channel case. We also compare the outage capacity with the performance of MIMO-OFDM systems employing powerful error correcting codes based on low-density parity-check codes when, due to finite frequency or time interleaving, there is only a small number of fading blocks per codeword.
Effectively and Efficiently Supporting Grid and Cloud Integration via a DBMS-based Framework

This paper provides anatomy, models and functionalities of a DBMS-based systems for integrating Grids and Clouds. Our study starts from recognizing the similarity of some axioms of Grid and Cloud computing, still being these computational paradigms very different for what regards both computing and economic models. Our proposed system is centered along a well-designed DBMS schema that allows to obtain a seamless integration between Grids and IaaS Cloud providers. The paper details how images from a Cloud environment are deployed in reply to a specific task execution invoked from the (integrated) Grid environment, as well as other essential components of the proposed architecture (e.g., resource access and grant, user authorization, resource discovery and sharing, job and task management and distribution, integration with other computational platforms, and so forth).
High Resolution Delay Locked Loop for time synchronization with multi path mitigation

ACCURATE localization Systems, based on the measurement of the time of flight of a signal between radio devices, also known as Real Time Location Systems (RTLS) are becoming increasingly important especially in indoor applications. Due to severe multi path conditions, the largest problem for those RTLS systems is to detect the time of arrival of signals traveling over the direct line of sight path. We present issues of a new High Resolution Delay Locked Loop (HRDLL) architecture- that allows an efficient hardware implementation of a high resolution method for multi path mitigation, and demonstrate first results.
Pharmacological characterization of extracellular pH transients evoked by selective synaptic and exogenous activation of AMPA, NMDA, and GABAA receptors in the rat hippocampal slice.

1. Inhibitors of extracellular carbonic anhydrase (CAo) offer much promise as diagnostic tools in the study of the synaptic basis of activity-induced alkaline transients in the brain. However, most of the present information related to the effects of CAo blockers in nervous tissue comes from experiments that involve simultaneous synaptic activation of various types of postsynaptic receptor channels. In the present work, double-barreled H(+)-selective microelectrodes were used to study alkaline shifts in extracellular pH (pHo) evoked by selective synaptic and pharmacological activation of glutamate and gamma-aminobutyric acid (GABA) receptors in the CA1 cell body layer in rat hippocampal slices. Inhibition of CAo was achieved with the use of the poorly permeant carbonic anhydrase inhibitor, benzolamide (10 microM; applied in the bath solution) or the impermeant macromolecular inhibitor, prontosil-dextran 5000 (PD 5000; applied in microdrops). 2. Alkaline transients that were exclusively attributable to synaptic activation of glutamate receptors were induced by stimulation of Schaffer collaterals in the presence of picrotoxin (PiTX, 100 microM). An enhancement by the CAo inhibitors of these alkaline transients took place at all stimulus frequencies (5-200 Hz) and stimulus train durations (0.5-20 s) examined. 3. Inhibition of CAo enhanced the alkaline transients evoked by selective synaptic activation of alpha-amino-3-hydroxy-5-methyli-oxazolate- 4-propionic acid (AMPA)/kainate receptors in experiments involving stimulation of Schaffer collaterals in the simultaneous presence of PiTX and D-2-amino-5-phosphonopentoate (AP5, 40-80 microM). 4. Alkaline shifts evoked by selective synaptic activation of N-methyl-D-aspartate (NMDA) receptors were enhanced after inhibition of CAo as seen in experiments where Schaffer collaterals were stimulated in the simultaneous presence of PiTX and 6-cyano-2,3-dihydroxy-7-nitroquinoxaline (CNQX, 20-40 microM) in an Mg(2+)-free solution. 5. Benzolamide and PD 5000 also enhanced the alkaline shifts seen upon pressure injection of glutamate, AMPA, or NMDA. The glutamate-induced alkaline shifts were inhibited by AP5+CNQX, suggesting that uptake of glutamate did not significantly contribute to their generation. 6. Stimuli applied at 5-10 Hz in stratum radiatum close (within 0.5 mm) to the recording site evoked alkaline shifts that were blocked by CNQX plus AP5. In the continuous presence of the two glutamate antagonists, PiTX-sensitive alkaline transients were observed in response to brief high-frequency (20-100 Hz) trains consisting of 100 stimuli. Upon application of pentobarbital sodium (100 microM), these apparently monosynaptically evoked GABAA receptor-mediated alkaline transients were evident also at low stimulation frequencies (5-10 Hz).

Circularly Polarized Slot Microstrip Antenna for Harmonic Suppression

With the introduction of the circularly symmetrical slot near the coaxial feed location of the corner truncated square microstrip antenna patch, both the circular polarization and harmonic suppression performance can be realized in this antenna. Effectiveness of the circularly symmetrical slot for harmonic suppression is studied, including its affection to circular polarization performance of the antenna. Experimental results show that application of the circularly symmetrical slot near the coaxial feed location of the microstrip antenna patch can remarkably suppress the harmonic frequencies. Measured radiation patterns indicate that the forward radiation is suppressed by more than 10~20 dB at the second and the third harmonic frequencies compared to the reference antenna, while maintaining the circular polarization performance, the cross polarization, and the backward radiation.
Profiling Online Social Network Users via Relationships and Network Characteristics

Research on individuals in online social networks often requires the collection of personal information such as demographics. Due to both user privacy concerns and unformatted textual information, it is quite difficult to build a completely labeled social network directly. However, both social relations and network characteristics can help attribute inference to profile online social network users. In this paper, we propose several attribute inference models based on these two factors and implement them with Naive Bayes, Decision Tree and Logistic Regression. Also, to study network characteristics and evaluate the performance of our proposed models, we use a well-labeled Google employee social network extracted from Google+ to test the proposed models on inferring the social roles of Google employees. The experiment results demonstrate that the proposed models are effective in social role inference with Dyadic Label Model performing best.
Output Waveform Improvement of High Switching Frequency PWM Inverters Introducing Digital Signal Processing

A method to improve output current waveform of high switching frequency PWM inverters introducing digital signal processing is presented. For a given clock frequency of the digital PWM controller, the control resolution is inversely proportional to the switching frequency. Consequently, a higher switching frequency results in poorer control resolution. In the proposed method, poor resolution of a high switching frequency digital PWM controller is improved by a noise shaper which is widely used in class D digital audio amplifiers. The effectiveness of the noise shaper used in the three phase voltage source inverters is demonstrated by some experimental results employing a prototype implemented by a FPGA.
Thai Rate-Varied Vowel Length Perception and the Impact of Musical Experience

Musical experience has been demonstrated to play a significant role in the perception of non-native speech contrasts. The present study examined whether or not musical experience facilitated the normalization of speaking rate in the perception of non-native phonemic vowel length contrasts. Native English musicians and non-musicians (as well as native Thai control listeners) completed identification and AX (same–different) discrimination tasks with Thai vowels contrasting in phonemic length at three speaking rates. Results revealed facilitative effects of musical experience in the perception of Thai vowel length categories. Specifically, the English musicians patterned similarly to the native Thai listeners, demonstrating higher accuracy at identifying and discriminating between-category vowel length distinctions than at discriminating within-category durational differences due to speaking rate variations. The English musicians also outperformed non-musicians at between-category vowel length discriminations across speaking rates, indicating musicians’ superiority in perceiving categorical phonemic length differences. These results suggest that musicians’ attunement to rhythmic and temporal information in music transferred to facilitating their ability to normalize contextual quantitative variations (due to speaking rate) and perceive non-native temporal phonemic contrasts.
First evidence of dengue infection in domestic dogs living in different ecological settings in Thailand

Background Dengue is a vector-borne disease transmitted by Aedes mosquitoes. It is considered an important public health problem in many countries worldwide. However, only a few studies have been conducted on primates and domestic animals that could potentially be a reservoir of dengue viruses. Since domestic dogs share both habitats and vectors with humans, this study aimed to investigate whether domestic dogs living in different ecological settings in dengue endemic areas in Thailand could be naturally infected with dengue viruses. Methodology/Principal findings Serum samples were collected from domestic dogs in three different ecological settings of Thailand: urban dengue endemic areas of Nakhon Sawan Province; rubber plantation areas of Rayong Province; and Koh Chang, an island tourist spot of Trat Province. These samples were screened for dengue viral genome by using semi-nested RT-PCR. Positive samples were then inoculated in mosquito and dog cell lines for virus isolation. Supernatant collected from cell culture was tested for the presence of dengue viral genome by semi-nested RT-PCR, then double-strand DNA products were double-pass custom-sequenced. Partial nucleotide sequences were aligned with the sequences already recorded in GenBank, and a phylogenetic tree was constructed. In the urban setting, 632 domestic dog serum samples were screened for dengue virus genome by RT-PCR, and six samples (0.95%) tested positive for dengue virus. Four out of six dengue viruses from positive samples were successfully isolated. Dengue virus serotype 2 and serotype 3 were found to have circulated in domestic dog populations. One of 153 samples (0.65%) collected from the rubber plantation area showed a PCR-positive result, and dengue serotype 3 was successfully isolated. Partial gene phylogeny revealed that the isolated dengue viruses were closely related to those strains circulating in human populations. None of the 71 samples collected from the island tourist spot showed a positive result. Conclusions/Significance We concluded that domestic dogs can be infected with dengue virus strains circulating in dengue endemic areas. The role of domestic dogs in dengue transmission needs to be further investigated, i.e., whether they are potential reservoirs or incidental hosts of dengue viruses.
Novel fabrication of an SnO2 nanowire gas sensor with high sensitivity

We fabricated a nanowire-based gas sensor using a simple method of growing SnO2 nanowires bridging the gap between two pre-patterned Au catalysts, in which the electrical contacts to the nanowires are self-assembled during the synthesis of the nanowires. The gas sensing capability of this network-structured gas sensor was demonstrated using a diluted NO2. The sensitivity, as a function of temperature, was highest at 200 °C and was determined to be 18 and 180 when the NO2 concentration was 0.5 and 5 ppm, respectively. Our sensor showed higher sensitivity compared to different types of sensors including SnO2 powder-based thin films, SnO2 coating on carbon nanotubes or single/multiple SnO2 nanobelts. The enhanced sensitivity was attributed to the additional modulation of the sensor resistance due to the potential barrier at nanowire/nanowire junctions as well as the surface depletion region of each nanowire.
Manoeuvrability of a master-slave manipulator with different configurations and its evaluation tests

_Recently, much research on master-slave manipulators with different configurations (MSM-DC) has been conducted, but the manoeuvrability between different structural arms has not been sufficiently discussed. Thus, an MSM-DC with six degrees of freedom (DOF) using an orthogonal-type master arm has been developed and its manoeuvrability has been studied with the aid of some basic experiments. The results were as follows: (1) the MSM-DC can be operated as easily as a conventional MSM that uses a replica master arm; (2) the slave arm position and the reflecting force of the master arm are correctly generated by coordinate transformation between the slave arm and the master ann; (3) the master-slave mode is suitable for performing a fine task, compared with the joystick mode; and (4) the function of changing the transformation point, which is newly proposed, from the master arm to the slave arm is effective in carrying out a task which has a revolving point. In addition, quantitative evaluation of the manoeuvr.
The Effect of Context on the Intelligibility of Hearing and Deaf Children's Speech

This study examines the effect of redundancy of information on the intelligibility of hearing and deaf children's speech. Listeners, including those experienced and inexperienced with respect to the speech of the deaf, heard two kinds of stimuli: (1) test words in sentences that varied in the amount of redundant information available, and (2) test words excised from these sentences and presented to the listeners as isolated words. For both groups of children, test words heard in sentences were perceived correctly more often than the same words heard in isolation. However, the effect of redundant information on intelligibility was opposite to that reported for adults (Lieberman, 1963). That is, in the speech of both hearing and deaf children, the scores for test words segmented from sentences with high redundancy were greater than scores for test words segmented from sentences with low redundancy. This suggests that children are not using the same production strategies as adults to assist listeners. The data also do not support the hypothesis that experienced listeners to deaf speech achieve higher intelligibility scores than inexperienced listeners by simply making better use of context.
An Improved Repetitive Control for Active Power Filters with Three-Level NPC Inverter

Due to the difficulty of handling nonlinear loads for traditional active power filter(APF) with two-level inverter in high voltage high power grid, this paper researches three-level active power filters. This paper presents an improved repetitive scheme to control the shape of ouput current waveform. The design process of each part in the repetitive controller is presented. Q(z) is designed as a notch zero phase shift filter which degrade the high order harmonic severely with close-to-unit gain at low and medium frequency band. The revised filter, the phase compensator and the repetitive gain is also given. The control method has fast dynamic convergence rate and little static misadjustment. The experiment results illustrate that the performance of the proposed approach is satisfactory.
Book Review: Counseling Women: A Narrative, Pastoral Approach

questioning, the creation of healthy rituals and ceremonies, the role of the Bible, ways to meet local therapists, and the benefits of collaboration. Of particular interest and value are selected guided imageries created by Bilich. The case of Teresa threads the book. A troubled woman with Dissociative Identity Disorder (formally known as Multiply Personality Disorder), Teresa was abused physically, emotionally, and spiritually by her mother, an uncle, and a cousin. As Bilich worked with Teresa in a healing process, Carlson began meeting with Mimic, one of Teresa's ten alters. Collaboration between Bilich, Carlson, and Bonfiglio offered Teresa, according to the authors, a fuller experience than traditional psychotherapy alone could have offered. Carlson demonstrated how a minister, in collaboration, can help a therapist to move beyond a single focus on pathology and begin to ask God's help in discovering the image of God within the survivor, A minister can become another important source of support and help bring the survivor back into community. Bilich demonstrated how a therapist can help a minister through collaboration-with limit setting, for example. As professionals, the authors know how holistic healing happens and how healthy love and relationships develop. Both the client and the reader benefit from their collective wisdom. Each author, too, claims growth spiritually, emotionally, and professionallyas a result of their collaboration, along with profound changes in the way each works. I have two observations about the book that I offer as thoughts, not necessarily criticisms. First, it might surprise some to see these authors' occasional unconventional clinical interventions, i.e., Bilich seeing Teresa outside of the office and Carlson taking out Teresa's garbage. Second, as a former parish pastor for a number of years, I was surprised that clinical supervision of a parish support group was not perceived by Bilich and company as of greater importance. However, these observations do not detract from my assessment that the book makes for a unique and valuable resource. The book's bibliography is quite adequate, utilizing a broad range of supporting literature and resources, and the appendices are useful. Overall, the book is a practical, quality book, and is quite user-friendly. I recommend Shared Grace to anyone engaged in ministry leadership, therapy, or supervisory positions. Exciting to me is how this volume opens the door for other clinicians concerned with the collaboration between spirituality and psychotherapy, perhaps from a more systemic perspective.
