Transient Stability Simulation of Power System Including Wind Generators

Abstract : Recently the wind power generation has attracted special interest and many wind power stations are being in service in the world. In the wind power stations, induction machines are mostly used as a generator. Since induction machines also have a stability problem like the transient stability of synchronous machines, it is important to analyze the transient stability of power system including wind power stations. This paper presents a model of induction generators, develops methods of power flow calculation and transient stability simulation of power system including induction generators, and presents considerations on the characteristics of transient stability of induction generators on the basis of numerical simulations.
Proteins Homologous to p47 phox and p67 phox Support Superoxide Production by NAD(P)H Oxidase 1 in Colon Epithelial Cells*

Superoxide production by phagocytes involves activation of a multi-component NADPH oxidase. Recently, several homologues of the catalytic component of the phagocyte oxidase, gp91 phox , were identified in various tissues. Here we describe two proteins, p41 and p51, with significant homology to two cytosolic components of the phagocytic oxidase, p47 phox and p67 phox . Like p47 phox , p41 contains an amino-terminal Phox homology domain, two SH3 domains, and a conserved carboxyl-terminal, proline-rich motif. Similarly, p51 is homologous to p67 phox , containing four amino-terminal tetra-trico-peptide repeats, a conserved “activation domain” motif, a PB1 domain, and a carboxyl-terminal SH3 domain. The highest levels of p41 transcript are detected in the colon and in other gastrointestinal tissues that express Nox1, the predominant gp91 phox homologue in these tissues. In contrast, the p51 transcript showed a more widespread expression pattern, suggesting that it may support other tissue-specific oxidases. Mouse colon in situ hybridization detected both transcripts in the epithelial cells of colon crypts. Heterologous
Characterization and potential of Pigeon Pea; Cajanus cajan L. Mill sp. Phytoestrogen on rat ovary

Objectives: The objective of this study was to analyze the estrogenic compounds in pigeon pea seeds and the effect of the plant seeds to rat ovaries development. Materials and Methods : The Cajanus cajan seeds were extracted, and to elucidate its content, liquid chromatography-mass spectrometry (LC-MS), and gas chromatography (GC)-MS analysis were employed. 24 Sprague-Dawley female rats were divided into three experimental groups and feed with C. cajan solution. The experimental groups were: P 0 (control/without C. cajan solution), P 1 (24 g:24 ml), and P 2 (8 g:24 ml). The experimental treatment by C. cajan was for 36 days. On the 37 th day, rats were dissected to examine the ovary and liver organs. Results: Based on LC-MS analysis, it was obtained that C. cajan seeds contain several phytoestrogens. GC-MS analysis showed that C. cajan seeds contain up to 7.91945 µg/kg of 17 β -estradiol. The observations showed a normal liver tissue structure, and there is no necrosis identified in the lobules of the hepatic sinusoids. The ovarian tissue structure of rats in the P 0 treatment group appeared normal. Some germinal follicular developments were detected in ovarian tissue of P 1 and P 2 treatment groups. Conclusion: C. cajan shows potential as a natural estrogenic substance that is effective and safe for further application in human hormone replacement therapy.
Income Inequality and Economic Growth: Empirical Evidence from Bangladesh

The main purpose of this work is to explore the relationship between income inequality and economic growth in Bangladesh. The study is based on time series data starting from 1973 to 2016 of Bangladesh. In this paper, we used the Augmented Dickey-Fuller (ADF) test for checking stationary of series. This study gives a hint that all the afore-mentioned series are stationary at first difference. This paper also incorporated the Johansen test for co-integration and Vector error correction model (VECM) to test the long run relationship between income inequality and economic growth rate. The results of the study indicate that economic growth and income inequality are co-integrated. This approach suggests that an inverse relationship exists between income inequality and economic growth rate. In other words, the higher economic growth rate results in lower income inequality and lower economic growth rate leads to higher income inequality. We find that income inequality plays a negative and significant role in economic growth. Keywords : Income inequality, Economic growth, ADF, Cointegration test, VECM, Bangladesh.

Aggregation behavior of one-patch inverse patchy particles: an experimental and numerical study

Hypothesis Inverse patchy colloids (IPCs) are promising building blocks to create new materials using their self-organization. For example, the control of the self-assembly of oxide-based IPCs is interesting for ceramic shaping. Thus, the synthesis of silica based IPCs as well as a detailed study of their behavior in suspension are presented in this paper. Fluorescent silica particles are partially modiﬁed in surface by grafting amine groups using a Pickering emulsion route. Zeta potential measurements, sedimentation tests and confocal microscopy observations are carried out to analyze the aggregation of the obtained particles in aqueous suspension as a function of the patch size and of the pH. Brownian dynamics simulations are also performed to better understand the aggregate structures. The aggregation of the synthesized silica-based IPCs can be tuned by modifying both the patch size and the pH of the suspensions. Diﬀerent aggregate structures, from elongated to compact ones, are obtained. This control of aggregation makes such particles promising to build new ceramic materials.

H 2 Rich Gas Production from Different Leaves

: In order to obtain the most favorable pyrolysis process for producing the highest yield of syngas from a range of leaf plants, slow pyrolysis, fast pyrolysis and microwave pyrolysis of apple tree leaves, bamboo leaves, cypress leaves, sycamore tree leaves, and winter green leaves were investigated. The results showed that, the microwave pyrolysis showed the highest gaseous product yields on all the 5 different kinds of leaves; the apple tree leaves, sycamore leaves and wintergreen leaves showed higher yields of gas products than bamboo leaves and cypress leaves across all the kinds of pyrolysis. The experimentally determined higher heating values (HHV) of bio-chars from different leaves ranged from 20-28 MJ/Kg, which are comparable to some coals. For the same kind of leaves, the HHV of bio-chars via different kind of pyrolysis did not change significantly. However, the HHV of bio-chars from different leaves performed differently with the bio-char from wintergreen leaves showing the highest HHV, which reached around 27 MJ/Kg; on the contrary, the HHV of bio-chars from bamboo leaves were the lowest values , which is only 20~22 MJ/Kg. For the gaseous products, the total amount of CO, H 2 , CO 2 and CH 4 reached 95% for the gaseous products from all the 3 kinds of pyrolysis treatments. Importantly, compared with slow and fast pyrolysis, the microwave pyrolysis of different leaves shows the highest content of CO and H 2 , and the lowest contents of CO 2 , the HHV of gaseous products of different leaves via the same pyrolysis treatment showed similar values, but different when the pyrolysis process is different for the same leaves. The HHV of gaseous products via microwave pyrolysis are the highest among different pyrolysis process, while the gaseous products HHV via fast pyrolysis are lowest. We therefore conclude that the microwave pyrolysis is a proper process for the H 2 rich gas production from natural leaves. Furthermore, the addition of acid, bases and salts as catalysts for the pyrolysis did not result in any significant activity and products changes during microwave pyrolysis process in our study.
Sintering of Ti-based biomedical alloys with increased oxygen content from elemental powders

Revived interest for beta Ti alloys with increased oxygen content is motivated by the prospect of achieving material with low modulus and high strength simultaneously. Fine tuning of amount of oxygen and beta stabilizing elements is critical for achieving good mechanical properties. This study shows that powder metallurgy method of spark plasma sintering is capable of producing Ti-Nb-Zr-O alloys from elemental powders. This simple approach allows for quick sampling and production of several alloys with various chemical composition. Elemental powders were mixed with appropriate amount of titanium dioxide to achieve Ti-29Nb-7Zr-0.7O alloy. Sintering was performed at 1400 1500 °C for 15 – 30 minutes.
UTC Time Transfer for High Frequency Trading Using IS-95 CDMA Base Station Transmissions and IEEE-1588 Precision Time Protocol

Abstract : Today, High Frequency Trading (HFT) requires low latency and knowledge of UTC time in capital markets where a difference of better than one millisecond provides a competitive advantage to trading firms. HFTs co-locate high speed computer systems in rented space next to the market centers to reduce latency of raw data, giving them advanced knowledge of the market orders. Better than 10-microsecond accuracy to UTC can be achieved using Code Division Multiple Access (CDMA), in compliance with Telecommunications Industry Association (TIA/EIA) Standard IS-95 and IEEE-1588 Precision Time Protocol (PTP) without routing an external antenna. This paper will present a method to provide UTC time using CDMA and PTP to these trading firms, why microsecond accuracy is required, and the performance of UTC time transfer as compared to GPS-derived UTC time.
LEO-Ring-Based Communications Network

This paper continues the development of a concept for a low-earth-orbit-based optic-fiber-communication system that may ameliorate some limitations of present space communications systems. Starting with an assumption that a circum-terra ring can be deployed in LEO, a high-bandwidth, optical-fiber-based, communication system has been proposed as the first of a system of LEO and higher-orbit (MEO) rings for different purposes. These rings about the Earth would complement existing terrestrial and space communications networks and thereby improve global connectivity and throughput. In particular, networking issues necessary for both initial and expanded-ring system communications are addressed.

Optimized Batch Policy Evaluation in the Presence of Monotone Responses

In batch policy evaluation the goal is to predict the value of a policy given some historical data. A specific example, which motivated the approach pursued in this thesis, is to predict the probability of putting a natural wildfire out given some specific configuration of dispatched resources, such as helicopters, planes, trucks, and firefighters of various kinds. The general structure of problems like this is that the more resources are deployed, the higher success rate we expect to see: the response is a monotone function of the resources dispatched. In this thesis, we investigate the question of what are the best ways of estimating success probabilities of policies in problems that exhibit such a monotone structure. In particular, viewing the problem as a multiobjective optimization problem where the optimization variables are parameters describing the estimators and the objectives correspond to different problem-instances (in the wildfire application these correspond to different conditions under which the fire may happen), we propose various ways of optimizing estimation accuracy. More specifically, when resource levels are discrete and one-dimensional (or totally ordered) and focusing on minimum variance point estimation and unbiased estimators, it is found that natural optimization objectives lead to convex optimization problems that can be solved efficiently. One of the main contributions of the thesis is the careful experimental comparison of the various optimization objectives with Monte-Carlo simulations. As a second main contribution, a similar investigation is carried out for comparing alternative strategies that produce interval estimates.
Ultra-Wideband Microstrip Filter Design with Super-Shaped Defected Ground Structures

Ultra-wideband (UWB) microstrip filter design has been proposed by applying defected ground conductor structures designed with the superformula approach. Simultaneously, the effects of the materials used in the designs on the filter properties have been examined. Once the filter characteristics have been determined, the filter design has carried out in the AWR program. The filter structure has been designed based on an 8 GHz center frequency fifth-order Chebyshev response ultra-wide bandpass filter. The filter model designed in AWR has transferred to the HFSS program, and the effect of FR4 and RO3035 materials on filter characteristics have been investigated. The various number of defects, each shaped with superformula, is opened to the base conductor, and their effects are observed. The parameters in the superformula proposed by Johan Gielis have been calculated in the MATLAB program. PCB productions of the designed filters have been made, and experimental measurements have been taken with the Anritsu spectrum analyzer. When the results obtained from electromagnetic simulation programs have compared with the experimental measurement results of the filters produced, it has been seen that the results are consistent with each other.
Changes in Coastal Ecosystems in the NE Pacific Ocean

, Abstract Regime shifts and El Niño events can be viewed as natural large scale experiments that involve changes in salinity, temperature, nutrients, trace metals, and subsequent shifts in species composition in the ecosystem. The impacts of the 1997-98 El Niño event off the northwest coast of British Columbia revealed distinct changes in nutrients, phytoplankton and zooplankton. During the 1997-98 El Niño, the coastal area where the summer nitrate was < 1 µM, was 250,000 km 2 larger than during the 1999 La Niña. Surface nitrate concentrations in 1998 were half of the concentrations in the 1970s. In contrast, during the 1999 La Niña, the mixed layer depth was 20 m deeper which increased the winter nutrient levels. Stratification was very pronounced in 1998 due to the increased temperature and this produced a bottom-up effect of a decrease in the productivity of the plankton communities through decreased nutrient concentrations (i.e. increased N limitation). During the 1997-98 El Niño, there was a lower total zooplankton biomass and shifts in community composition (reduced abundance of endemic boreal and temperate species and an increase in abundance of California species). Although the changes were most extreme in 1998, these changes in the zooplankton biomass and composition had been progressively developing off the BC coast throughout the 1990s. Therefore, even though the El Niño originates in the tropics, the effects are propagated poleward and there was a poleward shift of the west coast marine ecosystem, partially due to the stronger northward current flows. The 1977 regime shift demonstrated the importance of the carrying capacity of the ocean on fish stocks such as the Pacific salmon.
THE IMPACT OF THE INTERNET OF THINGS ON ESTABLISHED BUSINESS MODELS A multiple case study of Swedish insurance companies

The insurance industry has long been suffering from profitability and growth issues due to the increasing commoditization of insurance solutions, which has forced insurers to engage in destructive “ premium wars ”. Digitalization and technology advancements are only set to increase these pressures even further by shifting market boundaries and increasing the level of “digital sophistication” expected by customers. Ultimately, these pressures are forcing insurance companies to rethink the business models they have employed for so long and look beyond “business as usual”. One technology that might allow for insurers to stand out in this commoditized market is the Internet of Things (henceforth: IoT). This paper aims to study the impact of the IoT on the business model of insurance companies. With the help of the business model canvas, this paper provides the reader with an in-depth understanding of how IoT applications affect the different blocks that constitute the business model of insurance companies. Moreover, this paper aims to provide the reader with an understanding of the challenges and risks related to the implementation of the IoT, and how these might be mitigated. In order to do this, a multiple case design was chosen where semi-structured interviews were held with four different Swedish insurance companies currently working with different IoT-centred solutions. Additionally, the paper follows a qualitative research strategy with an abductive approach to theory generation. as premium discounts. Moreover, with the insurance industry being recognized for its conservatism, insurers will also need to make use of change management and enterprise-wide training to create a corporate culture more accepting of change and business model innovation. Lastly, the IoT also creates opportunities for new players to disrupt the insurance industry. For this reason, first-movers will have to develop data-driven capabilities that are difficult to replicate in order to create a sustainable competitive advantage.

Carbon isotope discrimination during litter decomposition can be explained by selective use of substrate with differing δ 13C

Temporal dynamics of C isotopic composition ( δ 13 C) of CO 2 and leaf litter was monitored during a litter decomposition experiment using Arbutus unedo L. , as a slow decomposing model substrate. This allowed us (1) to quantify isotopic discrimination variation during litter decomposition, and (2) to test whether selective substrate use or 5 kinetic fractionation could explain the observed isotopic discrimination. Total cumulative CO 2 -C loss ( C L ) comprised 27% of initial litter C. Temporal evolution of C L was simulated following a three-C-pool model. Isotopic composition of respired CO 2 ( δ RL ) was higher with respect to that of the bulk litter. The isotopic discrimination ∆ (L / R) varied from − 2‰ to 0‰ and it is mostly attributed to the variations of δ RL . A three-pool model, 10 with the three pools di ﬀ ering in their δ 13 C, described well the dynamic of ∆ (L / R) , in the intermediate stage of the process. This suggests that the observed isotopic discrimination between respired CO 2 and bulk litter is in good agreement with the hypothesis of successive consumption of C compounds di ﬀ ering in δ 13 C during decomposition. However, to explain also 13 C-CO 2 dynamics at the beginning and end of the incubation 15 the model had to be modiﬁed, with discrimination factors ranging from − 1‰ to − 4.6‰ attributed to the labile and the recalcitrance pool, respectively. We propose that this discrimination is also the result of further selective use of speciﬁc substrates within the two pools, likely being both the labile and recalcitrant pool of composite nature. In fact, the 2‰ 13 C enrichment of the α -cellulose observed by the end of the experiment, and 20 potentially attributable to kinetic fractionation, could not explain the measured ∆ (L / R) dynamics. as a model substrate to experimentally test the kinetic fractionation hypothesis. Our hypotheses were farther explored by model simulations.
