Development of Mobile Applications with Functions in the Cloud through the Model Driven Approach: A Systematic Mapping Study

Currently, a growing interest is being caused by mobile applications which have functions implemented in the cloud (MobileApps-FC). Improvements related to the portability of these applications among different platforms and different service providers are a critical need. Model Driven Development (MDD) constitutes one of the alternatives to address portability issues. This work presents a systematic mapping study that analyzes different proposals that apply MDD to the development of MobileApps-FC and that, at the same time, consider the improvement of the portability of such applications. Even though we have identified just a few studies related to our subject of interest, the validation experiences that are presented in them, encourage the adoption of MDD to address portability issues. However, further validation experiences that consider more complex cases in industrial environments will be required to justify the benefits of MDD in a substantial manner.

ITR / P 1-12 1 Prototype Manufacturing and Testing of Components of the ECH Upper Launcher for ITER

The main purpose of the Electron Cyclotron Heating (ECH) Upper Launcher at ITER is to provide local current drive in order to control plasma instabilities with the main focus on the stabilisation of neoclassical tearing modes (NTMs) and the sawtooth instability. The injection of 20 MW mm-wave power at 170 GHz is guided into the plasma by a mm-wave system which is installed in 4 of the 18 upper port plugs of the ITER vacuum vessel. The structural system of these so-called Upper Launchers, housing the mm-wave system, consists of two units, namely the blanket shield module (BSM) which forms the plasma facing component and the launcher main structure with removable internal shield blocks. It has to be designed for rough operation conditions as nuclear heating and enormous mechanical loads during plasma disruptions (EM-loads). The development of the structural design is accompanied by computational analyses, prototype manufacturing and prototype testing. Especially for structures with complex geometry, the optimum manufacturing route has to be determined regarding both technical and economical aspects. On the basis of a characteristic section of the BSM (called BSM corner prototype) different manufacturing routes were evaluated. The front part of the BSM is exposed to volumetric nuclear heating of up to 3 W/cm and to guarantee sufficient cooling it is designed with a double wall shell, which allows heat removal by internal meandering cooling circuits. Concerning the requirements on leak tightness, mechanical strength and geometrical precision, manufacturing of a double wall structure with internal cooling channels is a main challenge. Two BSM-corner prototypes were manufactured one by brazing of semi-finished parts and the other one by Hot Isostatic Pressing (HIP) and dedicated tests regarding pressure loss and cooling efficiency were performed. For the experimental part the Launcher Handling and Test Facility (LHT) at KIT was used to test prototypes under ITER relevant conditions. The results were compared with appropriate calculations and numerical FEM/CFD analyses performed with respect to flow characteristics, heat transfer and pressure loss of cooling water. In this paper the experience obtained on prototyping is presented and the importance of prototyping for design validation is pointed out.
The effectiveness of using methods two-stage for cross-domain sentiment classification

Traditional sentiment classification approaches perform well in sentiment classification but traditional sentiment classification approaches does not perform well with learning across different domains. Therefore, it is necessary to build a system which integrates the sentiment orientations of the documents for every domain. However, this needs much labelled data involving and much human labour as well as time consuming. Thus, the best solution is using labelled data in one existed in source domain for sentiment classification in target domain. In this paper, a two-stage approach for cross-domain sentiment classification is presented. The First Stage is building a bridge between the source domain and the target. The Second Stage is following the structure. The study shows that the mining of intrinsic structure of the target domain brings a considerable effectiveness during the process of sentiment transfer. This is a typical mining approach comparing to previous approaches basing on information from the source domain to address the task of sentiment transfer, which does not depend on intrinsic structure of the target domain. Experimental results on sentiment classification with a two-stage approach indicate that the effectiveness outperforms other traditional methods.
EFFECTS OF BAMBOO BIOCHAR AMENDMENT ON THE GROWTH AND PHYSIOLOGICAL CHARACTERISTICS OF FOKIENIA HODGINSII

Biochar (BC) as a soil amendment has become an encouraging practice due to its role in enhancing soil fertility and plant growth. Measurement of plant physiological attributes has been considered a necessary approach for the evaluation of this practice. Influence of BC on growth and physiological attributes of Fokienia hodginsii remains elusive. Therefore, the present study compares the efficacy of bamboo BC amendment at different levels on the growth and physiological attributes of F. hodginsii. BC was applied to soil with four different levels as Bo (Control), BB5 (5 g kg of soil), BB20 (20 g kg of soil) and BB80 (80 g kg of soil) and seasonal variation in chlorophyll pigments and photosynthetic rate were measured by constructing the light-response curve by using the modified model of rectangular hyperbola. Moreover, biochemical attributes, final biomass and soil physiochemical properties were also compared among seedlings treated with different BC levels. The results revealed that the addition of BC at higher dose significantly increased the chlorophyll pigments, photosynthetic rate and biochemical attributes compared to Bo. Moreover, compared to Bo, amendment of BB20 and BB80 in soil increased the morphological characteristics with a maximum increase of 29% in biomass with improved NPK dynamics. Overall, these findings support the idea that BC amendment into the soil can alleviate the physiological performance of these conifer seedlings by improving seedlings health with an appropriate supply of nutrients. Its addition in soil can be a promising tool for reforestation, but its impact on soil varies with BC feedstock and soil type.

Design and Fabricate the High Sensitivity and Stable Optocoupling Sensor

A novel photodetector array (PD) and the high sensitivity transimpedance amplifier (TIA) were designed and fabricated for predicting response time based on the optocoupling sensor, implemented in a standard 0.35 μm BCD technology. Based on response time equivalents and the architecture of the optocoupling sensor the response time of the PD were detailed analyzed. The circuit structure and the adjustable gain theory of the TIA module was clarified detailed. At a wavelength of 840 nm, from -25 °C to 125 °C, the simulation results showed that the PD has a high-speed and stable capability. The test results confirm the response time of the whole sensor is 205 ns and 153 ns and the response time would not change with the variation of the temperature. Copyright © 2013 IFSA.
Numerical Simulation of Compressible Flow Over a Deep Cavity

A transonic turbulent flow over a deep cavity is studied with the OpenFOAM code for LES (Smagorinsky model) and unsteady RANS (κ − ε and κ − ω models) and compared with available experimental and computational data. The main feature of deep cavities is the sound field that is too intense that leading to fatigue and vibration issues on the structures. So it is also done a simulation on a control device to reduce the emitted noise of the cavity. In general, LES simulations are in a much better agreement with experimental and computational data. Finally, the noise reduction was achieved successfully by slanting the aft wall.

Temporal Variation and Reproduction of Microseism H / V Spectral Features in the Osaka Sedimentary Basin with an Irregular-Shaped Interface

Beyond the traditional framework of the one-dimensional velocity structure, the horizontal-to-vertical spectral ratio (HVSR), of microseisms (microtremors with a frequency of about 1 Hz or lower) in areas where the sediment-bedrock interface has irregular topographies, was calculated by finite differential method (FDM)-based simulation. The HVSRs derived from the FDM simulations were both well reproduced in terms of not only the peak frequency (HVfp) but also the spectral curves for complex geological regions. Microseisms originate from the ocean-bottom pressure (the exciting force) characterized by the significant height and period of ocean waves. Therefore, the temporal change of the HVfp and its peak value, of microseism records obtained from spatially different distributions of the amplitude (the power) of the exciting forces scattered in an oceanic region where the investigated area is surrounded, was also reproduced.
Degradation of Residual Jatropha Oil by a Promising Lipase-Producing Bacterial Consortium

The potential of using lipase-producing bacteria in degrading the residual oil from Jatropha curcas L. biodiesel wastewater was assessed. Nine bacterial isolates obtained from mangrove areas in the Philippines and seven isolates from biodiesel wastewater were qualitatively and quantitatively screened for lipase activities. The three most promising bacteria (Arthrobacter sp. BOcMJL-12, Bacillus cereus BDF-2 and Pseudoalteromonas sp. BOcMFW-2), with lipase activities of 19.33, 35.67 and 19.50 U/mL, respectively, were selected and evaluated, singly or in combination, for residual Jatropha oil degradation efficiency. The highest oil degradation efficiency of 94.84% was attained using the three isolates in a consortium. The conditions for oil degradation (medium composition, initial medium pH, initial substrate concentration and culture incubation time) by the three bacteria in combination were also partially optimized using the Random Balance Designs. The oil degradation assay, under partially optimized conditions (Medium #5, pH 7 and 1% residual Jatropha oil substrate), revealed that the mixed culture containing the three most promising bacteria could degrade up to 96.99% of residual Jatropha oil after 7-8 d of incubation with continuous agitation. This bacterial consortium may be used as a promising strategy for the treatment of lipid-rich wastes.
Sequence Logo Visualization based on Gestalt Perception – Novices vs Experts

Sequence logo is a popular graphical method for displaying the conservation characteristics of a sequence motif profile. Studies have found that decision making biases and misused of sequence logo occur due to the differences in individual perception, knowledge and experiences. The aim of this study is to identify the differences between the novices and experts in visualizing sequence logo based on Gestalt perception. 52 participants were involved in an online survey and independent t-test was used to analyse the data obtained. Results shown that there are significant differences in the perception and needs between novice and expert users. Visual cues and detailed information display are required by novice users whereas experts prefer a simple but more functional representation in the sequence logo. Therefore, it is essential to improve the sequence logo visualization in the colour, grouping, information display and interactivity of the tool in order to support the needs of various users.
DEIM Forum 2012 D 6-5 Toward modeling the I / O behavior of MapReduce applications

Map-Reduce is a very popular framework that is often used for very large-scale data mining and processing. Although many recent works introduce models of the Map-Reduce system, these existing models ignore the non-linearity of disk I/O performance under contention, which is a critical aspect of estimating the performance of data-intensive applications. To utilize multi-core machines, multiple tasks are often scheduled simultaneously on one node, and these tasks can interfere with each other accessing the same disk. In this paper, we give a preliminary model to estimate the I/O behavior of Map-Reduce applications and evaluate its viability.
NETWORK ANALYSIS OF ANTENNA BASED ON SCATTERING PARAMETERS

Antenna design involves many electrical and mechanical parameters. The most important electrical parameters include radiation patterns, gain, directivity, input impedance, bandwidth, and efficiency. This paper develops a new form of two port network analysis of an antenna system based on scattering parameters (S-parameters) of an antenna element and its radiation pattern. In this formulation, antenna radiation is considered in terms of electromagnetic coupling between the test antenna and a probe antenna.
Detection and Classification of Acoustic Scenes and Events 2018 Challenge MULTICHANNEL ACOUSTIC SCENE CLASSIFICATION BY BLIND DEREVERBERATION , BLIND SOURCE SEPARATION , DATA AUGMENTATION , AND MODEL ENSEMBLING Technical Report

Detection and Classification of Acoustic Scenes and Events (DCASE) 2018 Challenge Task 5 can be regarded as one type of multichannel acoustic scene classification. The important characteristic of the Task 5 is that a microphone array may be put at different locations between the development dataset and the evaluation dataset, so we should not exploit location-dependent spatial cues but location-independent ones to avoid overfitting. The proposed system is a combination of front-end modules based on blind signal processing and back-end modules based on machine learning. To avoid overfitting, the front-end modules employ blind dereverberation, blind source separation, etc., which use the spatial cues without machine learning. The back-end modules employ onedimensional-convolutional-neural-network-(1DCNN)-based architectures and VGG16-based architectures for individual front-end modules, and all the 89 probability outputs are ensembled.
Simulation of Viscous Flows with a Gridless Particle Method

The aim of this paper is to present the numerical simulation of the evolution of the viscous, low Reynolds flows in two-dimensional cases with the use of the Smoothed Particle Hydrodynamics (SPH) method. This work is considered as the first step towards the simulation of complex three-dimensional flows, which occur in impulse water turbines. The method was originally developed for solving problems of astrophysical nature and belongs to the meshless methods, as it does not require any computational grid. A set of descrete fluid particles is used to represent the continuous fluid, and their trajectories are being calculated in a Lagrangian sense through time. The 2D test cases examined in this paper are the Couette and the Poiseuille Flow, and the basic problem of the liquid column collapse (Dam Break). For the first two test cases the numerical results were tested against analytical solutions from the literature, while for the third test case experimental measurements were used for the validation of the calculations. The agreement of the numerical results with the corresponding analytical and experimental data is quite good and encouraging towards the use of the SPH method in modelling of more complex, unsteady and multiphase flow fields, while the performance of the algorithm referring to the speed of the calculations and the qualitative results is remarkable. Key-Words: Smoothed Particle Hydrodynamics (SPH), Dam Break, Couette and Poiseuille Flow, Numerical Modelling
Wheeled hopping robot with combustion-powered actuator

While exploring complex environments, conventional mobile robots can overcome obstacles of limited height and jumping robots can overcome obstacles several times their own size. When jumping motion and wheeled or tracked motion are combined to form a composite motion, robots have even better ability to traverse rugged terrain. Therefore, we designed a wheeled hopping robot with a novel combustion-powered actuator and carried out structural design and experimental studies. The combustion-powered actuator has a unique inlet scheme and good sealing performance and is easy to install. The jump height equation was obtained by analyzing the combustion process. With the help of orthogonal array design methods, the factors that affect the wheeled hopping robot’s jumping height were analyzed to improve its key design parameters and optimize its jumping performance. Finally, experiments were performed with the actuator and the wheeled hopping robot. When the stoichiometric ratio of the mixed fuels nears complete combustion, the combustion-powered actuator can jump 7.5 m high with a payload of 3.75 kg and its own weight of 1.25 kg, and the wheeled hopping robot can jump 4.5 m high with a payload of 6 kg. Evaluating the robot’s performance in terms of energy efficiency reveals that it has a significant jumping advantage.
DEPOSITION OF A-SI LAYERS FOR HETEROJUNCTION SOLAR CELLS ON AN INDUSTRIAL SCALE

In this work the recent results concerning inline deposition of amorphous silicon obtained with a PECVD tool from Meyer Burger Germany (MBG) are presented. The depositions are done with an adapted MAiA tool which for this matter contains radio frequency linear plasma sources for the intrinsic as well as the doped amorphous silicon layers. In order to investigate the properties of these layers/layer stacks, especially concerning passivation quality and selectivity, we prepared various sample structures to determine minority carrier lifetime/implied open-circuit voltage, band bending and electrical properties. Minority carrier lifetimes of up to 7 ms and average implied open-circuit voltages of above 730 mV are verified for intrinsic amorphous silicon. We could proof a sufficient band bending for both nand p-doped and demonstrate an n-doped inline process which leads to external open-circuit voltages above 700 mV and pseudo fill factor values above 80 %. It is also shown for the layer stack consisting of intrinsic and n-doped amorphous silicon that we can reach a sufficient net doping to obtain required selectivity of the contact for the extraction of excess charge carriers.
