Modeling and Simulation MPC-DSTATCOM for Power Quality Improvement

-In this paper, a novel model predictive current control strategy is proposed for DSTATCOM to improve the power quality in distribution system. Unlike classical control schemes, the proposed method neither requires current PI controllers nor modulators at switching signal generation stage. The discrete-time model of the converter, filter and terminal voltage are used to predict the future behavior of the compensating currents for each of the eight possible switching states. The control method decides a switching state in which the actual currents are closer to their references. In this first part, proposed method is verified through extensive simulation in Matlab platform and a comparative analysis is made with HCC and SMC current control schemes. It has been found that total harmonic distortion of load compensation is well within the allowable range of IEEE standards with achievement of unit power factor. Keywords—finite control set (FCS); model predictive control (MPC); Distribution Static Compensator; Power quality

Software Platform for 3 D Model Conversion and Management

In any industry, if a business promotes its products to the right people in the correct manner, it becomes the leader in that industry. Marketing has evolved over the years as the technology becomes better and better. Over the years, marketing was done in the form of door to door sales to billboards and then on electronic media. Now we are in the golden age of technology, where marketing as well as planning can be done in the form of Augmented Reality. Architects can measure and create layout plans of the space using Augmented Reality or people can select furniture by placing them in their living rooms and looking from all sides to see if it is a perfect match. Having an Augmented Reality app is not a straightforward task. Every major field of science uses different 3D file formats to create and manage their 3D models. Using those 3D models in an Augmented Reality may not be possible as the underlying Augmented Reality frameworks may not read those formats. Adding runtime 3D models to Augmented reality applications is also a major challenge. In this thesis, a software as a service (SaaS) solution is developed that addresses some of the issues related to Augmented reality applications. These issues are converting different 3D file formats to a single 3D file format that can be used in Augmented Reality applications and that 3D file format can also be rendered at runtime. This thesis presents the development process of a software platform where three different applications, a user interface, a 3D model editor and viewer, and a backend application, are developed. The details of the inner functionalities of each application with future work and potential improvements of the platform are also discussed.

Sonoflex: Embroidered Speakers Without Permanent Magnets

We present Sonoflex, a thin-form, embroidered dynamic speaker made without using a permanent magnet. Our design consists of two flat spiral coils, stacked on top of each other, and is based on an isolated, thin (0.15 mm) enameled copper wire. Our approach allows for thin, lightweight, and textile speakers and does not require high voltage as in electrostatic speakers. We show how the speaker can be designed and fabricated and evaluate its acoustic properties as a function of manufacturing parameters (size, turn counts, turn spacing, and substrate materials). The experiment results revealed that we can produce audible sound with a broad frequency range (1.5 kHz - 20 kHz) with the embroidered speaker with a diameter of 50 mm. We conclude the paper by presenting several applications such as audible notifications and near-ultrasound communication.
Taxation and Unemployment Benefits with Imperfect Goods and Labor Markets

We consider a model in which the labor market is characterized by search frictions and there is monopolistic competition in the goods market. We introduce proportional income taxation and unemployment benefits with Government balanced budget constraint. Then, we evaluate the effects of both more competition in the goods market and higher unemployment benefits on labor market equilibrium and equilibrium tax rate. We show that more competition has a positive effect on equilibrium unemployment and the Government budget. Higher unemployment benefits can be financed either by higher tax rate or increasing goods market competition. Liberalization policies could permit: a) to avoid an increase in unemployment if we allow some rise in the tax rate; b) to decrease unemployment if they are incisive enough to keep the tax rate unchanged.

Stable isotope composition of Late Pleistocene-Holocene Eobania vermiculata (MUller, 1774) (Pulmonata, Stylommatophora) shells from the Central Mediterranean basin: Data from Grotta dOriente (Favignana, Sicily)

This paper presents stable isotopic results (oxygen and carbon) from both modern and Late PleistoceneHolocene shells of the land snail Eobania vermiculata (Müller, 1774) from Favignana Island (Sicily). It aims to contribute to the understanding of climate and vegetation history of this region during formation of Upper Palaeolithic, Mesolithic and Meso-Neolithic deposits of Grotta d’Oriente (ORT). Results from both an evaporative model (FBM) and an empirical regional isotopic model (i.e. linear relation between oxygen isotopic composition of shells (d18Os) and those of local precipitation (d18Op)) indicate that the d18Os values of modern specimens are mainly controlled by local temperature, relative humidity and d18Op at the time of snail activity. Data also suggest that the modern snails are nocturnally active almost all-year round in the study area. The carbon isotopic compositions of shells (d13Cs) of the same specimens indicate a diet prevalently (or exclusively) composed of C3 vegetation. The d18Os values of Late Pleistocene specimens suggest that climate conditions at w14.2 ka cal BP were similar to the present day, in agreement with additional d18Os records from southern Italy. By contrast, early-middle Holocene shells are notably 18O-depleted and suggest wetter conditions, possibly combined with a decrease in isotopic composition of precipitation source, compared to the present day. When compared with regional palaeoclimatic records a large-scale isotopic response to millennial-scale changes in atmospheric and hydrological conditions (e.g. enhanced rainfall) in the central-eastern Mediterranean is observed during the early-middle Holocene. The d13Cs of Late Pleistocene and Holocene specimens are consistently higher than those of modern ones. For the Late Pleistocene, this could be reasonably explained in terms of water-stressed vegetation. On the other hand, this seems to be less valid for Holocene counterparts when the climate was wetter. Probably d13Cs values result from the combination of distinct competing factors, involving atmospheric CO2 concentration, seasonal water budget, vegetation type-cover and other carbon sources. Results reveal coherent relationships between regional d18Os and d13Cs, demonstrating that Late Pleistocene-Holocene land snail shell remains from archaeological sites may provide useful snapshots of past seasonal climate conditions. 2011 Elsevier Ltd and INQUA.

Effect of Surface Morphology of Scaffold with Lines of Micro Ridges on Deformation of Cells

The effect of micro ridges of the scaffold on deformation of cells has been studied in vitro. Several parallel lines of micro ridges have been made on a disk of transparent polydimethylsiloxane. The height, the width, and the length of the rectangular ridge are 0.001 mm, 0.003 mm, and 0.5 mm, respectively. Variation has been made on the interval of the ridge: 0.001 mm, 0.003 mm, 0.005 mm and 0.007 mm. Five kinds of cells were used in the test. C2C12 (mouse myoblast cell line), L929 (fibroblast connective tissue of mouse), Neuro-2a (a mouse neural cell line), 3T3-L1 (mouse fat precursor cells), and HUVEC (human umbilical vein endothelial cells). Cells were seeded on the micro pattern at the density of 2000 cells/cm and cultured for 24 hours. The cells were observed with a microscope. The experimental results show that C2C12 lengthen along the line of ridge of 0.003 mm interval. The effects of the micro pattern depend on the kind of cells.
Modeling and Forecasting Income Inequality in the United States

Recently, an idea has emerged that “the rich are getting richer and the poor are getting poorer”. Using tax data from Piketty, Saez, and Zucman (2017) (updated in the World Wealth & Income Database) and internal microdata from the Current Population Survey (1975-2015), this paper models inequality and performs pseudo-out-of-sample (2012-2015) and true out-ofsample (2016-2018) forecasts for 5 income inequality measures. The lowest forecast errors from the best models are found for distributional metrics, as compared to top income shares. While macroeconomic indicators, human capital, and labor force metrics often enhance models, measures of skill biased technological change are not found to be robust predictors of inequality trends. Naı̈ve approaches often outperform more complex models and forecasts differ between models by <4% for all variables.
Study of Temperature in Five Phase Induction Motor with Z-Source Inverter and Traditional Inverter at Low Speed

This paper presents the experimental study of temperature at various parts of five phase induction motor with PWM drive and compared the temperature at various parts of the five phase induction motor with Z-source inverter drive. It utilizes an exclusive Z-source network to link the main inverter circuit to the power source. The ZSource converter employs a unique impedance network to couple the converter main circuit to the power source, thus providing unique features that cannot be obtained in the traditional voltage-source and current-source converter where a capacitor and inductor are used, respectively. The ZSource inverter system using MOSFETS provide ride through capability during voltage sags, reduce line harmonics, improves power factor and high reliability. Analysis and experimental results obtained by implementing the inverter circuit using Z-source inverter drivewill be presented in this paper. Keywords–Induction motor drive, Z-source, five phase inverter drive.
THE ROLE OF FOREIGN DIRECT INVESTMENT IN THE ECONOMY OF THE CZECH REPUBLIC

Foreign direct investment play in a very open economy such as the Czech Republic a crucial role, including the involvement of small and medium-sized enterprises in the export. Foreign direct investment form the basis of industrial investments. Even small changes in the economic activities of large enterprises have a significant impact on the budgets of the state, regions and municipalities. It is not possible to identify the relationship of supranational companies and small and medium-sized enterprises as purely competitive in the national market. In addition to the economic effects, foreign direct investment play a crucial role in the development of human resources, the use of applied research and development and these businesses contribute to the image of the state and region. Large Enterprises are a key part of the economy of the Czech Republic and the EU.
ViPSN: A Vibration-Powered IoT Platform

In this article, we introduce a vibration-powered sensing node (ViPSN), a programmable Internet-of-Things (IoT) platform for the development of vibration-powered or motion-powered sensing and transmitting systems. It leverages the exploitation and utilization of ambient vibration energy by using a piezoelectric transducer. The roles and relations of six necessary modules, including energy generation unit (EGU), energy transduction unit (ETU), energy enhancement unit (EEU), energy management unit (EMU), energy user unit (EUU), and edge demonstration unit (EDU) are discussed in detail. In particular, an enhanced EMU is proposed by making necessary complements to an extensively used off-the-shelf integrated circuit (IC) solution for piezoelectric transducers. It provides more comprehensive energy storage indicating signals, such that the sensing, computing, and transmitting tasks can be carried out more robustly by keeping a good awareness of the remaining energy. Owing to the enhanced EMU design, vibration energy in various forms, such as intermittent and transient ones, can be more effectively harvested and utilized. The performance of ViPSN is evaluated, in terms of its lifetime and Quality of Service (QoS), under different vibration scenarios. The inclusive design and affiliated opensource project of ViPSN help build a new ecosystem for the research and development of vibration- or motion-powered IoT systems.
Code Smell Detection Techniques and Process: A Review

— A code smell is a hint that something has turned out badly some place in your code. The idea of code smells was introduced to characterize various different types of design shortcomings in code. Code and design smells are poor solutions to recurring implementation and design problems. They may hinder the evolution of a system by making it hard for software engineers to carry out changes. In this paper, we reviewed code smell detection tool like: Décor, InFusion, JDeodorant, PMD, Stench Blossom, etc. Furthermore, we discussed various code smells detecting techniques. Code clones are indistinguishable fragment of source code which may be embedded deliberately or inadvertently. Reusing code pieces through reordering with or without minor adjustments is general undertaking in programming advancement. We’ve examined several papers to explore various tools and techniques used for code smell. In addition, we reviewed the process of code smell detection.
Salary-Determinants of School Teachers in Gilgit City

This objective of this study is to explore and investigate the salary determinants of the school teachers in Gilgit (the capital city of GilgitBaltistan). The data has been collected from 100 school teachers (35 governments, 40 private and 25 NGO-private school teachers) of 20 schools via questionnaire. We used Analysis of Variance (ANOVA) model, the dummy variable regression approach to find out the salary variances in respect to different characteristics of the school teachers. Results show that salary variances are highly linked with institutional affiliation of a teacher, gender differences, experience years, seniority and teaching status of a teacher. While the models for teacher’s academic qualification and professional degrees reveals surprisingly ambiguous or very little effect towards salary. Our finding assumes valuable features for researchers and policy makers in the field of education and economics.
Surfactin from Bacillus subtilis attenuates ambient air particulate matter-promoted human oral cancer cells metastatic potential

Recently, many studies have indicated that ambient air particulate matter (PM) can increase the risk of oral cancer. The most common malignant tumor in the oral cavity is oral squamous cell carcinoma (OSCC). Usually, cancer cell migration/invasion is the most important cause of cancer mortality. Matrix metalloproteinase-2 (MMP-2) and MMP-9 have been shown to play important roles in regulating metastasis and the tumor microenvironment. Here, we studied the anti-cancer effects of surfactin, a cyclic lipopeptide generated by Bacillus subtilis, on cancer cell migration and invasion. Surfactin suppressed PM-promoted cell migration and invasion and colony formation of SCC4 and SCC25 human oral squamous cell carcinoma cell lines. We observed that PM induced MMP-2 and MMP-9 expression, which was inhibited by surfactin. Transfection with p65, p50, c-Jun, c-Fos, p85, p110, Akt, mammalian target of rapamycin (mTOR), or interleukin-6 (IL-6) siRNA markedly inhibited PM-induced MMP-2 and MMP-9 expression. Moreover, surfactin could reduce Akt, mTOR, p65, and c-Jun activation and IL-6 secretion induced by PM. Finally, we proved that transfection with Akt, p65, or c-Jun siRNA significantly inhibited PM-induced IL-6 release. Taken together, these results suggest that surfactin functions as a suppressor of PM-induced MMP2/9-dependent oral cancer cell migration and invasion by inhibiting the activation of phosphoinositide 3-kinase (PI3K)/Akt/mTOR and PI3K/Akt/nuclear factor-κB (NF-κB) and activator protein-1 (AP-1)/IL-6 signaling pathways.
When the Differences in Frequency Domain are Compensated: Understanding and Defeating Modulated Replay Attacks on Automatic Speech Recognition

Automatic speech recognition (ASR) systems have been widely deployed in modern smart devices to provide convenient and diverse voice-controlled services. Since ASR systems are vulnerable to audio replay attacks that can spoof and mislead ASR systems, a number of defense systems have been proposed to identify replayed audio signals based on the speakers' unique acoustic features in the frequency domain. In this paper, we uncover a new type of replay attack called modulated replay attack, which can bypass the existing frequency domain based defense systems. The basic idea is to compensate for the frequency distortion of a given electronic speaker using an inverse filter that is customized to the speaker's transform characteristics. Our experiments on real smart devices confirm the modulated replay attacks can successfully escape the existing detection mechanisms that rely on identifying suspicious features in the frequency domain. To defeat modulated replay attacks, we design and implement a countermeasure named DualGuard. We discover and formally prove that no matter how the replay audio signals could be modulated, the replay attacks will either leave ringing artifacts in the time domain or cause spectrum distortion in the frequency domain. Therefore, by jointly checking suspicious features in both frequency and time domains, DualGuard~can successfully detect various replay attacks including the modulated replay attacks. We implement a prototype of DualGuard~on a popular voice interactive platform, ReSpeaker Core v2. The experimental results show DualGuard~can achieve 98% accuracy on detecting modulated replay attacks.
Effect of Diabetes Mellitus on Tuberculosis Treatment Outcomes among Tuberculosis Patients in Kelantan, Malaysia

Background: There is growing evidence that DM may play an important role in the occurrence of unsuccessful TB treatment outcomes. This study was undertaken to examine the prevalence of DM among TB population, compare the profile of TB patients with and without DM and determine the effect of DM on unsuccessful treatment outcomes among TB patients in Kelantan state, Malaysia from 2012 to 2016. Methods: A cross sectional study was conducted in Sep 2017 using data from registered TB cases in Kelantan state, Malaysia from 2012 to 2016. The profile of TB patients with and without DM were compared in univariable analysis. Multiple logistic regression was used to determine association between DM and unsuccessful treatment outcomes. Results: A total of 1854 TB patients were diagnosed with DM. The annual proportion was ranging from 26 to 29%. TB patients with DM had an older age, live single, low educational status, poor chest x ray finding and diagnosed with smear positive sputum compared to TB patients without DM. TB patients with DM had three times higher risk to develop unsuccessful TB treatment outcomes compared to TB patients without DM (95% CI 2.47–3.58; P = 0.012) in multivariable analysis. Conclusion: Those with DM had the worst prognosis of TB outcomes among the significant risk factors. TB control program in Malaysia will need to expand efforts to focus on treatment of TB-DM patients to improve their cure rates in order to achieve the goals of tuberculosis elimination.
