Published: September 2015

Intermittent wind energy in producing optimal power flow could lead to unstable generated power. Due to this, an energy storage that can release and absorb energy need to be used in order maintains the generated voltage at the permitted quality for the load. Nowadays, tons of energy storage systems are used in storing the energy. Flywheel energy storage system (FESS) becomes one of potential mechanism that can be used to smooth the voltage output of wind turbine due to its advantages. The aim of this study is to design and implement a FESS for critical load in a wind energy system that can store energy for a short time period. Then, period of the voltage generated by FESS using different capacitance is analyzed. FESS consists of a self-excited capacitance induction motor-generator set (SEIG), controller circuit and flywheel rotor. In this study, a three phase asynchronous induction machine is used as a motor-generator due to its simplicity, cheap, robust and less maintenance. The flywheel and SEIG-motor set could store the energy for a short period of time, which can be used to compensate for wind instability. Results show that FESS generates variable powers that compensate short time power to the wind system.

Published: September 2015

The purpose of this paper is compare between DC brushless fan and DC hybrid solar panel cooling system. The efficiency of PV module is depending on solar irradiance and ambient temperature. As temperature of PV module increase, the output current will increase but output voltage and output power will decrease and also vice versa. As solar irradiance increase, output current and output power will increase with linear and output voltage will increase with marginal and vice versa. The DC cooling system is a way to fix the issue of low efficiency of PV module with the intention to generate more electrical energy. To make an attempt to cool down the PV module, DC brushless fan and water pump with inlet/outlet manifold are built for constant fresh air movement and water flow circulation at the backside and front surface of PV module. The PV module with DC brushless fan cooling system increase 3.47 %, 29.55 %, 32.23 % in term of output voltage, output current, and output power respectively. It decrease 6.1 °C compare than to PV module without DC brushless fan cooling system. While PV module with DC hybrid cooling system increase 4.99 %, 39.90 %, 42.65 % in term of output voltage, output current, and output power respectively. It decrease 6.79 °C compare to PV module without DC hybrid cooling system. The efficiency of PV module with cooling system was increasing compared to PV module without cooling system, for the reason that the ambient temperature dropped significantly. An increase in efficiency of PV module, investment payback period of the system can reduce and the lifespan of PV module will be prolonged.

Published: September 2015

This paper presents a wind energy assessment for a resort island in the South China Sea that has a seasonal climate contributed by the monsoon seasons. The resort island selected for this study is Tioman, as it denotes the typical energy requirements of most resort islands in the South China Sea. The island depends primarily on diesel-fuel for electricity generation. However, diesel is subjected to expensive and unpredictable market values, high operation and maintenance costs, and poses environmental threats. Therefore, the potential for wind energy conversion system development is conducted in order to reduce the island’s diesel fuel dependency. The study starts with energy auditing and meteorological data collection. Subsequently, the wind energy potential is evaluated using Weibull distribution function. The results indicate that the wind speed vary according to seasons, where higher wind power can be generated during the northeast monsoon season than any other seasons.

Authors: Khammas Farhan , Hussein Suffer Kadhim , Usubamatov Ryspek , Mustaffa Mohmmad Taufiq
Published: September 2015

This paper reviews the available types of wind turbine which is one of the wind energy applications. The authors intend to give investors a better idea of which turbine is suitable for a particular setting and to provide a new outlook on vertical axis wind turbines. Wind technology has grown substantially since its original use as a method to grind grains and will only continue to grow. Vertical-axis wind turbines are more compact and suitable for residential and commercial areas while horizontal-axis wind turbines are more suitable for wind farms in rural areas or offshore. However, technological advances in vertical axis wind turbines that are able to generate more energy with a smaller footprint are now challenging the traditional use of horizontal wind turbines in wind farms. Vertical axis wind turbines do not need to be oriented to the wind direction and offer direct rotary output to a ground-level load, making them particularly suitable for water pumping, heating, purification and aeration, as well as stand-alone electricity generation. The use of high efficiency Darrieus turbines for such applications is virtually prohibited by their inherent inability to self-start.

A Robust Fuzzy-PI Pitch Angle Controller for Wind Turbine Systems
Authors: Ahmed Shaon , Rashid Mohd. Abdur , Yaakob S.B. , Malek F.
Published: September 2015

This paper presents a robust Fuzzy-PI controller to adjust the pitch angle of a grid integrated wind turbine. The pitch angle mechanism of a turbine blade allows it rotate on its own axis so that it can protect itself from high wind gust and release excessive stress from the mechanical structure. Although a classical PI controller has been widely used for this purpose, they cannot assure generator stability. The proposed Fuzzy-PI control system uses three control inputs and nine membership functions to make decision on pitch angle output. A wind speed model is devised to simulate real life turbulent wind condition. The simulation results show that the Fuzzy-PI controller is more suitable for turbine operation if it is subjected to heavy turbulence.

Authors: Albreem Mahmoud A.M. , binti Ali Azuwa
Published: September 2015

Block Data Transmission Systems (BDTS) are used in high speed wireless communication systems with time dispersive channel characteristics. Since Maximum Likelihood Block Detection (MLBD) requires huge amount of computation, Sphere Detection (SD) technique has been introduced as an alternative. This paper proposes an An Lattice Sphere Detection (AnLSD) technique for detection in block data transmission systems (BDTS). The An lattice structure offers more dense constellation points than the customary Zn lattice in SD technique. Thus, the proposed AnLSD uses An lattice generator matrix as the channel matrix, and uses the Gram matrix which is obtained from the generator matrix as part of the detection process. Simulation results show that the proposed AnLSD performs very close to the Exhaustive search (ES) using block size of 20 bits. It is also performing better than the other renowned methods tested under a channel with spectral nulls. The proposed AnLSD technique offers significant reduction in term of objective functions evaluation as compared to the other renowned methods.

Authors: Shihabudin Ismail Mohd , Hussain M.I. , Zain Zuraidah M. , Muhd Noorhafiza
Published: September 2015

This paper deals with a buffer allocation problem in unpaced μ-unbalanced production line. Unpaced line is referred to a line with workstations act independently and the material is not pulled by demand but in push mode. In this study, the production line is considered unpaced, μ-unbalanced but reliable. Mean processing time (μ) is the most difficult variable to fix constant in an actual production line due to the complexity of assembly process. The unbalance variance will become higher if the assembly process is more complex. The optimal buffer allocation need to be found for this particular type of production line so that it can maximize throughput rate and minimize total number of work-in-progress (WIP) on the line. This paper used a simulation method to simulate the throughput rate by given sets of buffer size. Based on the simulation results, a basic optimal buffer allocation (OBA) concept represented the characteristics of OBA for a production line was summarized. By applying the concept, a development of 6 Steps OBA tool is carried out. This tool could be utilized by a management in allocating the buffer during designing of the line layout.

In this research, an analysis is performed by using the concepts of the reliability and risks of units evaluated using a variance-covariance matrix and also the effect and expanses of replacement are measured. Mean-variance analysis is formulated as a mathematical programming with two objectives to minimize the risk and maximize the expected return. Finally, we employ a Boltzmann machine to solve the mean-variance analysis efficiently. At the end, the result of our method was exemplified. This method enables us to obtain a more effective selection of results and enhanced the effectiveness of the decision making process.

Pursuing an understanding of animal consciousness: Implications for animal morality and a creaturely theology
Authors: Du Toit Cornel W.
Published: September 2015

The importance of animals in the evolutionary history of homo sapiens comes to the fore in light of an increasingly trans-human techno-scientific environment. New research on consciousness, and animal consciousness in particular, has prompted questions relating to animal rights, animal morality and the emergence of a creaturely theology and theological primatology. The possibility of understanding nonhuman animals is investigated with reference to notions like consciousness, thinking, awareness, language and communication, including the importance of emotion in communication. Special attention is given to the nature of animal communication as it came to the fore in bonobo and other chimpanzee research. Building on the notion of awareness and communication, the article focuses on the notion of animal morality and comments on some aspects of a creaturely theology.
Inequality, the crisis, and stagnation
Authors: van Treeck Till
Published: September 2015

This article focuses on the macroeconomic implications of inequality by identifying four themes on which there seems to be growing consensus among many economists, especially in the various heterodox traditions, but also increasingly in the mainstream of the economics profession. The first theme on which there is growing consensus is the notion that the rise in inequality has contributed in an important way to the unsustainable rise in household debt in the United States and ultimately the financial and economic crisis starting in 2007. Second, there is the by-now widely held view that rising inequality at the international level has contributed to the so-called global imbalances in terms of national current-account positions. Third, there has recently been a shift in the focus of attention from merely looking at income inequality to analysing the longer-term implications of income inequality for wealth inequality. Fourth, the argument has been made that a high level of inequality can, generally speaking, be a cause of low economic growth, or even secular stagnation. The article gives a broad and non-technical overview on how these issues can be seen to be linked.

US household demand is well below its trend from prior to the Great Recession. We link weak demand to rising income inequality. The demand problem did not arise contemporaneously with higher income inequality because the bottom 95 percent of the income distribution went deeply into debt to maintain consumption growth despite their stagnant income growth. But we argue that the demand impact of greater inequality did appear in the aftermath of the recession. A calibrated Keynesian growth model shows that the lower income share of the bottom 95 percent can explain the deviation of the US economy from its pre-recession trend.
Bringing inequality back in
Authors: Boushey Heather
Published: September 2015

Economic inequality has traditionally not been the center of mainstream macroeconomic thought. Rethinking whether and how today's high economic inequality – along all axes, not just income – affects economic growth and stability is an increasingly relevant and important field of inquiry. This paper investigates how economic research can inform the debate on the relationship between inequality and growth. I define the relationship between inequality and growth as well as briefly review the literature on their relationship. Then, I outline the channels through which inequality may affect growth. And finally, I address possible avenues for public policy going forward.
Teaching monetary theory and monetary policy implementation after the crisis*
Authors: Lavoie Marc
Published: September 2015

The author reflects on the state of macroeconomic theory, and more specifically on how monetary economics is being taught in the aftermath of the global financial crisis. Whereas heterodox macroeconomic theory is very much alive due to the influx of a large number of contributions and contributors, the latter still have a hard time finding positions in the academic world, as journal and departmental ranking exercises have restricted so-called standards of excellence to the neoclassical approach. The crisis has not yet induced mainstream economists to open up to different approaches that put more emphasis on realistic features than on imaginary ones based on neoclassical micro-foundations. As an exemplar, the chapters on money and banking in two first-year textbooks are being examined, an orthodox one by Greg Mankiw and a heterodox one by Neva Goodwin et al. Unsurprisingly there is little to be learned about the crisis from Mankiw's book, while the book by Goodwin et al. devotes a large amount of space to the causes and consequences of the crisis. Still, Goodwin and her co-authors are not heterodox enough: they are less heterodox than a number of central bankers when it comes to a number of key features of monetary theory.
Investigating the observed sensitivities of air-quality extremes to meteorological drivers via quantile regression

Abstract. Air pollution variability is strongly dependent on meteorology. However, quantifying the impacts of changes in regional climatology on pollution extremes can be difficult due to the many non-linear and competing meteorological influences on the production, transport, and removal of pollutant species. Furthermore, observed pollutant levels at many sites show sensitivities at the extremes that differ from those of the overall mean, indicating relationships that would be poorly characterized by simple linear regressions. To address this challenge, we apply quantile regression to observed daily ozone (O3) and fine particulate matter (PM2.5) levels and reanalysis meteorological fields in the USA over the past decade to specifically identify the meteorological sensitivities of higher pollutant levels. From an initial set of over 1700 possible meteorological indicators (including 28 meteorological variables with 63 different temporal options), we generate reduced sets of O3 and PM2.5 indicators for both summer and winter months, analyzing pollutant sensitivities to each for response quantiles ranging from 2 to 98 %. Primary covariates connected to high-quantile O3 levels include temperature and relative humidity in the summer, while winter O3 levels are most commonly associated with incoming radiation flux. Covariates associated with summer PM2.5 include temperature, wind speed, and tropospheric stability at many locations, while stability, humidity, and planetary boundary layer height are the key covariates most frequently associated with winter PM2.5. We find key differences in covariate sensitivities across regions and quantiles. For example, we find nationally averaged sensitivities of 95th percentile summer O3 to changes in maximum daily temperature of approximately 0.9 ppb °C−1, while the sensitivity of 50th percentile summer O3 (the annual median) is only 0.6 ppb °C−1. This gap points to differing sensitivities within various percentiles of the pollutant distribution, highlighting the need for statistical tools capable of identifying meteorological impacts across the entire response spectrum.
Uncertainty and sensitivity in optode-based shelf-sea net community production estimates

Abstract. Coastal seas represent one of the most valuable and vulnerable habitats on Earth. Understanding biological productivity in these dynamic regions is vital to understanding how they may influence and be affected by climate change. A key metric to this end is net community production (NCP), the net effect of autotrophy and hetrotrophy, however accurate estimation of NCP has proved to be a difficult task. Presented here is a thorough exploration and sensitivity analysis of an oxygen mass-balance based NCP estimation technique applied to the Warp Anchorage monitoring station which is a permanently well mixed shallow area within the Thames river plume. We have developed an open source software package for calculating NCP estimates and air-sea gas flux. Our study site is identified as a region of net heteotrophy with strong seasonal variability. The annual cumulative net community oxygen production is calculated as (−5 ± 2.5) mol m−2 a−1. Short term daily variability in oxygen is demonstrated to make accurate individual daily estimates challenging. The effects of bubble induced supersaturation is shown to have a large influence on cumulative annual estimates, and is the source of much uncertainty.
Embryo coculture: A review
Authors: Melnick Alexis P. , Spandorfer Steven D.
Published: September 2015

Since the inception of in-vitro fertilization, various attempts have been made to improve in-vitro embryo development, therebyenhancing implantation and in turn, pregnancy rates. Coculture, the simultaneous culture of somatic cells together with theembryo, is one strategy that has been used to achieve this goal. We review the rationale behind the technique of coculture, currentmethods utilized, and the evidence supporting its use.
Application of Sigmoidal Gompertz Curves in Reverse Parallel Parking for Autonomous Vehicles
Authors: Chand Aneesh , Kawanishi Michihiro , Narikiyo Tatsuo
Published: September 2015

A new method for the planning and autonomous execution of a single-trajectory, velocity-independent, parallel parking manoeuvre for autonomous vehicles is presented. The procedure commences with the identification and pre-selection of a smooth sigmoidal trajectory known as the Gompertz curve in parametric format. Trajectory parameters are determined in real-time during the path-planning phase using an optimization scheme in order to generate a candidate path. The optimization scheme takes into account the maximum steering angles that can be physically realized and checks the generated candidate trajectory for collisions. Thereafter, the trajectory is reparametrized to arc-length format using the cubic interpolation method and the vehicle orientation at every point of the trajectory is deduced. Following that, values of the steering angle(s) are determined. In the final step, the vehicle uses dead-reckoning to follows the arc-length parametrized path in reverse in order to park itself in a single-manoeuvre. The proposed method is substantiated through both extensive simulations and real sensor data.
ARTE E PSICANÁLISE: UMA NOVA ABORDAGEM SOBRE A SUBJETIVIDADE NA CULTURA CONTEMPORÂNEA
Authors: Silva Ana Carolina Nunes
Published: September 2015

Neste presente trabalho, veremos por meio das análises do filósofo esloveno Slavoj Žižek e do historiador da arte Hal Foster, a importância de pensar a imbricação entre subjetividade e cultura através da psicanálise, já que o sujeito desta instância do saber se constitui a partir de sua exterioridade (Outro). Em sua potência crítica, a psicanálise pode acompanhar e acentuar a crise que conforma sujeito e cultura, de modo a assumir um papel na contínua transformação de ambos. O diálogo entre arte e psicanálise pode tornar inteligível “nosso tempo” para fazer ressoar o inatual, isto é, para tornar artificial aquilo que foge à compreensão imediata, convidando-nos a uma reflexão mais ampla. A arte contemporânea agencia intervenções críticas na cultura, convidando a experiências de subversão — e de reflexões sobre o sujeito e o mundo, entrecruzando-se com a psicanálise e a filosofia, entre outros campos do saber.

Published: September 2015

O presente artigo apresenta a figura do cyborg como própria para lidar com o atual estado de mútua incorporação entre orgânico e sintético. O entendimento dessa condição contribui com a aquisição de parâmetros para a visualização de mecanismos de interação que promovem a hibridização de objetos técnicos com o humano e na demarcação da relevância de seu entendimento para a análise das relações entre sujeito, interfaces e sistemas complexos de comunicação. Através do cruzamento de ideias de Derrik de Kerckhove, Lúcia Santaella, Bruno Latour, Vilém Flüsser, Caroline Jones, Donna Haraway e Gilbert Simondon, construímos um traçado da linguagem como primeiro aparato técnico agregado ao humano até a polifonia de vozes encontrada em personagens virtuais.
