Observed Relationships between Cloud Vertical Structure and Convective Aggregation over Tropical Ocean

AbstractUsing the satellite-infrared-based Simple Convective Aggregation Index (SCAI) to determine the degree of aggregation, 5 years of CloudSat–CALIPSO cloud profiles are composited at a spatial scale of 10 degrees to study the relationship between cloud vertical structure and aggregation. For a given large-scale vertical motion and domain-averaged precipitation rate, there is a large decrease in anvil cloud (and in cloudiness as a whole) and an increase in clear sky and low cloud as aggregation increases. The changes in thick anvil cloud are proportional to the changes in total areal cover of brightness temperatures below 240 K [cold cloud area (CCA)], which is negatively correlated with SCAI. Optically thin anvil cover decreases significantly when aggregation increases, even for a fixed CCA, supporting previous findings of a higher precipitation efficiency for aggregated convection. Cirrus, congestus, and midlevel clouds do not display a consistent relationship with the degree of aggregation. Lidar-ob.
Control and modeling of push-pull forward three-level converter for microgrid

Renewable energy sources are widely used in microgrid. Output voltage of them is often low and varies widely. Because diodes in three-level legs in traditional three-level (TL) converter are substituted by MOSFETs, the push-pull forward (PPF) TL converter is very suitable for wide and low input-voltage applications. It can operate at two-level and three-level modes. Modeling of the proposed converter is established. Control of the proposed converter is designed, which contains output voltage loop and current limit loop. In addition, control block diagrams of both modes can be simplified to one control diagram. By adding input voltage feedforward, influences of input voltage on output voltage and inductor current can be eliminated. The divider in the input voltage feedforward is simplified by two piecewise linear functions, which can be easily implemented by operational amplifiers. Therefore, cost can be reduced. Simulation results of a 1-kW PPF TL converter verify the theoretical analysis.
NETQOS Policy Management Architecture for Flexible QoS Provisioning in Future Internet

This paper is focussed on the NETQOS architecture for automated QoS policy provisioning, which can be used in future Internet scenarios by the different actors (i.e. network operators, service providers, and users) for flexible QoS configuration over combinations of mobile, fixed, sensor and broadcast networks. The NETQOS policy management architecture opens the possibility to specify QoS policies on a "business" level using ontology descriptions and policy management interfaces, which are specific to the actors. The business level policy specifications are translated by the NETQOS system into intermediate and operational QoS policies for automated QoS configuration at the managed heterogeneous network and transport entities. NETQOS allows QoS policy specification and dependency analysis considering service level agreements (SLAs) between the actors, as well as automated policy provisioning and adaptation. The interaction of the NETQOS components is based on a common policy repository. The particular focus of the paper is aimed to discuss ontology and actor oriented QoS policy specification and configuration for heterogeneous networks, as well as NETQOS QoS policy management interfaces at business level and automated translation of business QoS policies to intermediate and operational policy level.

Swelling Kinetics of Disulfide Cross-Linked Microgels

Hydrogels of 2-hydroxyethyl methacrylate (HEMA) cross-linked with N,N‘-cystaminebis(acrylamide) (CBA) were prepared inside microchannels using an in situ photopolymerization for the study of chemical-responsive microgels. By chemically reducing disulfide bonds with dithiothreitol (DTT), the cross-link density of the hydrogel network decreased, leading to an observable swelling of the hydrogel. To maximize swelling response, acrylic acid (AA) was copolymerized with HEMA and CBA to afford a pH/chemically-responsive hydrogel. The combination of a decrease in cross-link density and a driving force for swelling (deprotonation of AA) led to a fast swelling response. Hydrogel swelling switched between half- and first-order kinetics depending on hydrogel composition and de-cross-linking conditions. A direct relationship between the hydrogel swelling rate and the rate of cross-link cleavage was found. A linear dependence between the square of the swelling rate and DTT concentration suggests the possibility of usin.
Multi-layer cross-point binary oxide resistive memory (OxRRAM) for post-NAND storage application

Feasibility of the multi-layer cross-point structured binary oxide resistive memory (OxRRAM) has been tested for next generation non-volatile random access high density data storage application. Novel plug contact type bottom electrode (plug-BE) could reduce active memory cell diameter down to 50nm with smaller operation current and improved switching distributions. With 2 additional masks, one layer of plug-BE included cross-point memory array could be added on top of another one. No signal of inter-layer interference has been observed. Also, prototype binary oxide based diodes have been fabricated for the purpose of suppressing intra-layer interference of cross-point memory array
A simple acute myocardial infarction (Heart Attack) prediction system using clinical data and data mining techniques

Acute Myocardial Infarction (Heart Attack), a Cardiovascular Disease (CVD) leads to Ischemic Heart Disease(IHD) is one of the major killers worldwide. A proficient approach is proposed in this paper that can predict the chances of heart attack when a person is bearing chest pain or equivalent symptoms. We have developed a prototype by integrating clinical data collected from patients admitted in different hospitals attacked by Acute Myocardial Infarction (AMI). 25 attributes related to symptoms of heart attack are collected and analyzed where chest pain, palpitation, breathlessness, syncope with nausea, sweating, vomiting are the prominent symptoms of a person getting heart attack. The data mining techniques namely decision tree and random forest are used to analyze heart attack dataset where classification of more common symptoms related to heart attack is done using c4.5 decision tree algorithm, alongside, random forest is applied to improve the accuracy of the classification result of heart attack prediction. A guiding system to suspect the chest pain as having heart attack or not may help many people who tend to neglect the chest pain and later land up in catastrophe of heart attacks.
Cochlear Radio

In this paper we propose an analog to digital converter system for RF signals, the Cochlear Radio, which is bio-inspired in the ear of mammals (cochlea). The basilar membrane is mimicked by microstrip lines and the hair cells by mid-end ADCs. The proposed system relies on hybrid filter bank to perform the conversion of the analog input signal into a digital version of it. A prototype of the analog filter bank operating from 840 MHz to 1470 MHz was used. Simulation results revealed that it is possible to design the synthesis filter bank with low values of distortion and aliasing. Further developments of this technology can achieve the required bandwidth and dynamic range, with off-the-shelf ADCs, fulfilling the promise of Software Defined Radio (a radio capable of dealing with wideband signals).
The Moving Centre: Preferences for Government Activity in Britain, 1950–2005

The political ‘centre’ is often discussed in debates about public policy and analyses of party strategies and election outcomes. Yet, to date, there has been little effort to estimate the political centre outside the United States. This article outlines a method of estimating the political centre using public opinion data collected for the period between 1950 and 2005. It is demonstrated that it is possible to measure the centre in Britain, that it moves over time, that it shifts in response to government activity and, furthermore, that it has an observable association with general election outcomes.
A Clinical Study of Maternal and Fetal Outcome in Abruptio Placenta - Couvelaire Uterus a Preventable Obstetric Catastrophe

Introduction : Hemorrhage is the single most important cause of maternal death worldwide. Obstetrical hemorrhage accounts for almost half of all postpartum deaths in developing countries. Among them Abruptio placenta occurs in around 1% of all pregnancies. Aim of this study was to determine the maternal and fetal outcome in pregnancy complicated by abruption placenta in relation to the risk factors. Methods: This was a retrospective study conducted in the Department of Obstetrics and Gynecology, Mamata medical college, khammam from January 2010 to December 2014 for a period of five years. All pregnant women who were diagnosed with abruptio placenta after 28 weeks of gestation were included in the study. Patients were identified from the admission and labour room registers. Results: Total number of deliveries during the study period were 4000. Patients identified with abruptio placenta were 100, giving a frequency of 2.5%. Majority women were multigravidae and 56% of all the between 26-30 years of age. The mean gestational age at diagnosis was 34 ± 4.21 weeks. Vaginal bleeding was the most common clinical finding seen in 80% of the women, followed by blood stained amniotic fluid in 16% suggesting concealed abruption placenta. Fetal heart sounds were absent on admission in 65% of the women. Most common cause of abruption 44% was either patients with past history of pre – eclampsia or PIH in the present pregnancy. 9 patients with couvelaire uterus were identified and treated effectively. Among them, two patients died due to postpartum hemorrhage. Parity and gestational age were found to be significant risk factors for abruptio placentae. Conclusion: Abruptio placenta was associated with poor maternal and fetal outcomes. Early diagnosis and significant treatment of pre eclampsia during the antenatal period would prevent abruption and related complications.

On the influence of antenna integration on the radio link of UWB systems for consumer equipment

The design of UWB systems for consumer electronic application requires the integration of the antenna for aesthetical design reason. This paper discusses the influence of the integration on the performance of UWB antennas and the entire radio link. Investigations based on numerical simulations show that the antenna performance is drastically affected when the antenna is integrated into the chassis of an application when classical UWB antenna measures like radiation pattern, ringing or delay spread are observed. In order to investigated the impact of this degradation on the radio link between different applications like DVD player and PDA in a typical living room environment propagation modeling is performed. The research shows that the less ideal classical antenna measures have only minor influence on the entire link compared to the influence of the indoor channel.
The Power of Less: Exemplar-based Automatic Transcription of Polyphonic Piano Music

Transcription of polyphonic piano music is an important computer music problem and many sophisticated methods have been proposed for its solution. However, most techniques cannot fully utilize all the available training data eciently and do not scale well beyond a certain size. We develop an exemplar-based approach that can easily han- dle very large training corpora. We maintain transcription performance by only retaining 1% of the training data. The method is competitive with the state-of-the-art techniques in the literature. Besides, it is very ecient and can work in real time.
Speech-based emotion recognition and next reaction prediction

Communication through voice is one of the main components of affective computing in human-computer interaction. In this type of interaction, properly comprehending the meanings of the words or the linguistic category and recognizing the emotion included in the speech is essential for enhancing the performance. In order to model the emotional state, the speech waves are utilized, which bear signals standing for emotions such as boredom, fear, joy and sadness. In the first step of the emotional reaction prediction system proposed in this paper, different emotions are recognized by means of different types of classifiers. The second step is the prediction of a sequence of the next emotional reactions using neural networks. The sequence is extracted based on the speech signals being digitized at tenths of a second, after concatenating the different speech signals of each subject. The prediction problem is solved as a nonlinear auto-regression time-series neural network with the assumption that the variables are defined as data-feedback time-series. the best average recognition rate is 86.25%, which is achieved by the Random Forest classifier, and the average prediction rate of reactions by using neural networks is 60.30%.
Short-range point-to-point gigabit wireless transmission at 50 GHz

In this paper, we present a short-range point-to-point gigabit wireless transmission at 50 GHz utilising prototypes of simple transmitter and receiver front-ends. The particular prototypes have been assembled from millimetre-wave (MMW) components with WR15 and coaxial ports. The MMW transmitter generates an amplitude shift keying (ASK) modulated signal by mixing a polar non-return-zero (NRZ) of pseudo-random binary sequence (PRBS) with a word length of 211−1 and a local oscillator (LO) signal of 50 GHz. MMW coherent receiver with a low-pass filter has been employed to demodulate the ASK signal. For the digital baseband transmission at 50GHz, a BER of 10−11 has been achieved for 3.125Gbps wireless transmission with received RF power greater than -61dBm. The prototype MMW receiver imposes 3dB sensitivity penalty when bit rate is increased from 2.125 to 3.125Gbps.

Compact Medical Cyclotrons and their use for Radioisotope Production and Multi-disciplinary Research

Compact medical cyclotrons are conceived for radioisotope production in a hospital-based environment. Their design in terms of field shape, stability and radio-frequency (RF) is aimed at obtaining high intensity (>150 μA) beams at kinetic energies of the order of 20 MeV. To guarantee high performances, an optimization procedure during the commissioning phase is crucial as well as a regular preventive maintenance. Beyond radioisotope production, these accelerators can be the heart of a multi-disciplinary research facility once access to the beam area and beams down to the pA range are possible. The first requirement can be achieved by means of an external beam transport line, which leads the beam to a second bunker with independent access. Currents down to the pA range can be obtained by specific ion source, RF and magnetic field tuning procedures, opening the way to nuclear and detector physics, radiation protection, radiation bio-physics and ion beam analysis developments. On the basis of the experience gained with the cyclotron at the Bern University Hospital, the accelerator physics aspects of compact medical cyclotrons are discussed together with their scientific potential.
Detectability analysis for resistive open faults with dynamic supply voltage scaling awareness

Dynamic supply voltage scaling (DVS) is an efficient and practical design technique to reduce power consumption in VLSI devices. Due to the multiple voltage operating environment and the supply voltage dependent behavior of physical faults, obtaining a minimal test set which gives the best fault coverage is challenging. Researchers have showed that testing of resistive opens is best achieved at high supply voltage. However based on our experimental results on ISCAS-85 circuits it is shown that is not always the case for DVS enabled designs. This paper analyzes and identifies different detectability patterns for resistive open faults in such designs. Additionally it discussed the multi-VDD testing and its necessity to achieve 100% fault coverage.
Thermal and aqueous stability improvement of graphene oxide enhanced diphenylalanine nanocomposites

Abstract Nanocomposites of diphenylalanine (FF) and carbon based materials provide an opportunity to overcome drawbacks associated with using FF micro- and nanostructures in nanobiotechnology applications, in particular their poor structural stability in liquid solutions. In this study, FF/graphene oxide (GO) composites were found to self-assemble into layered micro- and nanostructures, which exhibited improved thermal and aqueous stability. Dependent on the FF/GO ratio, the solubility of these structures was reduced to 35.65% after 30 min as compared to 92.4% for pure FF samples. Such functional nanocomposites may extend the use of FF structures to e.g. biosensing, electrochemical, electromechanical or electronic applications.
