La innovación social digital colectiva y la administración. Propuestas para una visión más humana de la ciudad inteligente
Authors: López-Fogués Aurora , Fernández-Baldor Álvaro , Boni Alejandra
Published: November 2017

A partir del análisis de Santander, Valencia, Bilbao y Donostia, este artículo presenta la visión que estas ciudades tienen de la ciudad inteligente (CI). Asimismo, indaga en cómo las corporaciones locales interactúan con las experiencias de innovación social digital colectiva, entendidas como redes de personas y organizaciones que generan innovación mediante el uso de las tecnologías digitales con fines sociales y ambientales. Para el análisis hemos empleado un marco teórico basado en el desarrollo humano y la perspectiva multi-nivel de las transiciones socio-técnicas. Los resultados arrojan que el discurso de las ciudades sobre la CI quiere transitar hacía una visión participativa, pero aún está lejos de ella en su práctica. Esto es palpable en la manera que tienen las corporaciones de interaccionar con las experiencias de innovación social digital donde sigue predominando una práctica unidireccional e instrumental. Por otro lado, hemos analizado la visión de la CI y cómo se relacionan con la administración 21 experiencias de innovación social digital. Su idea de CI está más alineada con los valores del desarrollo humano, mientras que sus estrategias son muy diferentes: desde iniciativas que optan por no tener relación con la administración a otras que persiguen realizar incidencia.
Estrategia omnicanal para no usuarios del e-gobierno
Authors: Medina-Molina Cayetano , Manuel Rey-Moreno Manuel , Pérez-González Benito
Published: November 2017

Las organizaciones públicas vienen incorporando canales de distribución para que los ciudadanos puedan acceder a los servicios públicos. Si bien existían elevadas expectativas en relación a la adopción del e-gobierno por parte de los ciudadanos, las tasas efectivas de uso no están alcanzando los niveles deseados. Por ello se une un nuevo enfoque, la omnicanalidad, que sugiere la valoración de los canales en base a como ayudan a generar la mejor experiencia de uso de los usuarios respecto del total de los canales. El presente trabajo analiza el impacto que sobre la intención de uso del e-gobierno tiene que los ciudadanos vengan empleando la Administración Telefónica o Presencial. Tras una metodología cualitativa y cuantitativa, se establece cómo mientras para los usuarios de la administración telefónica la intención de uso del e-gobierno viene explicada por algunos de los factores favorecedores (expectativa de resultado e influencia social), en el caso de la Administración Presencial el modelo tiene una estructura dual en la que aparecen tanto favorecedores (expectativa de resultado) como inhibidores (inercia y hábito). De la dispar estructura de los modelos se derivan diferentes vías de actuación para lograr incrementar el uso del e-gobierno por parte de los ciudadanos.
Estratificación socio-espacial y por ingresos en los servicios de desarrollo infantil y cuidado en la Ciudad de Buenos Aires
Authors: Marzonetto Gabriela Lucía
Published: November 2017

En sociedades desiguales, las diferencias de acceso y calidad de los servicios educativos y de cuidado que prestan los establecimientos de desarrollo infantil condicionan las oportunidades de los niños de familias de menores ingresos. Considerando que Argentina no es ajena a este fenómeno, en este artículo se analiza si el modo en que se organiza socialmente el cuidado de niños y niñas en la Ciudad de Buenos Aires opera como mecanismo de estratificación social. Para responder este interrogante se parte de una estrategia metodológica que combina estadística descriptiva –test de diferencia de medias y comparación simple de medias de ingresos per cápita familiares por comuna y tipo de establecimiento de desarrollo infantil al que asisten los niños– e inferencial, mediante la aplicación de un modelo de regresión logística (modelo logit) que permita establecer significancia estadística en la correlación entre la asistencia a establecimientos de desarrollo infantil y los ingresos familiares y ponderar la probabilidad de concurrencia a estos establecimientos según el nivel de ingreso familiar.Este artículo pretende contribuir al debate sobre la estratificación y segmentación social presente en los servicios públicos, como los educativos y de desarrollo infantil, en la región.

Authors: Kalsum Ummu , Jinca M.Yamin
Published: November 2017

Fenomena suburbanisasi yang terjadi di kota Makassar mendorong terciptanya pusat-pusat aktivitas baru di kawasan pinggiran dan menimbulkan berbagai masalah baru, seperti masalah transportasi. Penelitian ini menjelaskan arah perkembangan kota di wilayah suburban, karakteristik pergerakan, kondisi pelayanan angkutan massal dan menemukan strategi pengembangan transportasi angkutan massal. Proses pengumpulan data dilakukan melalui observasi lapangan dan wawancara, kemudian dianalisis menggunakan mapping analysis, deskriptif kuantitatif, komparasi dan SWOT untuk menemukan strategi pengembangan. Hasil studi menunjukkan bahwa kota berkembang ke arah  Timur dan Selatan serta tidak sesuai dengan hierarki jalan. Disamping itu masyarakat suburban dominan melakukan perjalanan 5 kali dalam seminggu dengan waktu tempuh berkisar 30 menit. Pelayanan angkutan massal menggunakan bus (Bus Rapid Transit) masih rendah karena halte masih sulit dijangkau meskipun biaya penggunaannya sangat terjangkau dan memberikan kenyamanan lebih dibanding angkutan massal lainnya. Oleh karena itu diperlukan strategi pengembangan konsep transportasi yang bersifat mikro dan adaptif untuk diterapkan.
Implementation of Lossless Voice Data Communication using Network Streams on Embedded System
Authors: Prasetio Barlian Henryranu , Syauqy Dahnial
Published: November 2017

Smart home refers to the use of computers and information technology to control home appliances. The smart home system occupies sensors to acquire data for monitoring. One of the most important factors in designing a smart home system was the communication between devices that will be used. It requires high throughput and low latency communication so that monitoring can be done in real time and lossless. The communication network was designed to optimize the stream monitoring for smart home by reviewing the system throughput and latency. Lab-VIEW programming on My-RIO embedded systems was used to acquire accelerometer and voice data readings and send them to personal computer wirelessly. The network communication was designed by implementing network stream protocols between two applications which were planted in the personal computer and My-RIO system. The test results indicate that the network stream protocol did not require normalization of sensor data types while transmitting and receiving. The throughput values were affected by increasing buffer size but on certain conditions saturated throughput were experienced. The value of the latency is always stable with an average value of 13 ms even though the size of the buffer is enlarged.

Published: November 2017

Rainfall already became vital observation object because it affects society life both in rural areas or urban areas. Because parameters to predict rainfall rates is very complex, using physics based model that need many parameters is not a good choice. Using alternative approach like time-series based model is a good alternative. One of the algorithm that widely used to predict future events is Neural Network Backpropagation. On this research we will use Nguyen-Widrow method to initialize weight of Neural Network to reduce training time. The lowest MSE achieved is {0,02815;Â  0,01686; 0,01934; 0,03196} by using 50 maximum epoch and 3 neurons on hidden layer.

Subjectivité et projet. La critique patočkienne du concept heideggérien de "projet de possibilités"
Authors: Stanciu Ovidiu
Published: November 2017

Subjectivity and Project. Patočka's critique of Heidegger's concept "project of possibilities" The purpose of this article is to lay out the way the main aspects of Patočka's critical reading of Heidegger's fundamental ontology. More precisely, I intend to restate the central arguments Patočka raised against Heidegger's characterization of "understanding" (Verstehen) as a "project". In the first part, I will single out Patočka's project of an "asubjective phenomenology" by distinguishing it from another asubjective project (that of Aristotle) and from the subjective phenomenology. In the second part, I will examine some central theses Heidegger puts forth in §31 of Being and Time in order to show the inescapable difficulties they bring about. In the final part, I will describe the tenets around which Patočka's critical reading of Heidegger revolves. I will explore the two directions of this critique that correspond to the double orientation of asubjective phenomenology: a) on the one hand, the priority of the phenomenal field with regard to any subjective sense-bestowal; b) the importance of the phenomenon of corporeity for an accurate apprehension of subjectivity.
The Experiment of Night: Jan Patočka on War, and a Christianity to Come
Authors: Kočí Martin
Published: November 2017

In the wake of the present-day crises, social conflicts and growing divisions, Patočka's reflections on war and totalitarianism appear abiding. Moreover, the enigmatic language, which Patočka uses, especially in his late Heretical Essays, sounds provoking and paradoxical. This article elaborates on the hypothesis that Patočka's reflections provide us with something more than a historical analysis interpreting the wars of the 20th century, and the 20th century as a war. I will argue that Patočka finds an intrinsic link between modernity, as a particular mode of being, and war and totalitarianism as unavoidable consequences of such a mode of being. To describe this situation, Patočka puts forth the dialectic of the light of day and the darkness of night. Paradoxically, in a somewhat mystical turn, Patočka gives preference to the night as the driving force of transgressing modern logic and the defective mode of modern being which throws crowds to the hell-fire of modern warfare. Against this background, this paper will present an innovative reading of Patočka's reflections as a specific search for an adequate spiritual response to the discontents of modernity. I will suggest that the trajectory of Patočka's thought can be read through the lens of a particular philosophy of religion, even though Patočka never elaborated on this avenue explicitly. Thus, I will propose that Patočka's thought opens up the possibility of reconsidering a heretical idea of Christianity that is coming after Christianity.
Patočka, the meaning of the post-European spirit and its direction
Authors: Merlier Philippe
Published: November 2017

The Europe that was born from Plato's "care for the soul" can today no longer be recognized; it has been replaced by the self-management of the economic EU. How can we now come back to a Europe concerned about its soul, the others, and the world, reinventing itself as a new nation? Jan Patočka's thoughts on post-Europe can show us the way.Starting from some clarifications on the definitely European initial meaning that Patočka detects in Socrates' "care for the soul", the purpose of this article is to examine what in this European spirit can be saved in the post-European age, and to what extent a "European nation" can still make sense. This analysis leads us, building on the visionary texts written in the seventies by Patočka, to rethink the possibilities of a reformation of European reason, and a métanoïa of Post-Europe.

Hypocrisy and Moral Authority
Authors: Isserow Jessica , Klein Colin
Published: November 2017

Hypocrites invite moral opprobrium, and charges of hypocrisy are a significant and widespread feature of our moral lives. Yet it remains unclear what hypocrites have in common, or what is distinctively bad about them. We propose that hypocrites are persons who have undermined their claim to moral authority. Since this self-undermining can occur in a number of ways, our account construes hypocrisy as multiply realizable. As we explain, a person’s moral authority refers to a kind of standing that they occupy within a particular moral community. This status is both socially important and normatively precarious. Hence, moral agents are right to be vigilant when it comes to hypocrisy, and are often justified in their outrage when they detect it. We further argue that our view can preserve what is attractive in rival accounts, while avoiding their associated problems.
Critiques to the «liberal peace» construction in Sub-Saharan African post conflicts settings
Authors: Zirion-Landaluze Iker
Published: November 2017

With the end of the Cold War, international peace-building policies were geared to promote a concrete understanding of the peace in post-conflict contexts, most of them in sub-Saharan Africa. This model, called «liberal peace» because it was based on the dominant Western (neo)liberal ideas of representative democracy, market economy and conflict resolution (formal, state-one and non-based in conflict transformation), has become currently hegemonic. In this article I discuss some of the main critiques that have been made to this model implementation in Sub-Saharan Africa: first, his (neo)colonizer character, directed to protect Western interests; second, the existence of internal contradictions in areas such as democracy and human rights; third, its technical and neutral nature, considered free of political, economic, or gender connotations; fourth, his alleged uniformity and homogeneity; and, fifth, the representation of African countries as contexts which should be «saved» and with no local agency.
Mechanisms of exclusion of the original populations in the speeches and representations of the Ecuadorian Buen Vivir and Bolivian Vivir Bien: the tutelage and the symbolic expropriation

This article have tried to take a close look at the (re)construction of identity among the indigenous populations with regards to State discourses and practices in the Ecuadorian Buen Vivir and the Bolivian Vivir Bien. By way of methodology of discourse analysis, I attempt to shed light on the progressive homogenization of indigenous diversity within a model of the «ideal indigenous person», which serves economic development policies that, far from reaching true plurinationality, seem to continue with patterns of the tutelage and displacement that started with the era of colonization.
Oil in Ecuador, 2000-2015: curse, blessing or just a resource?
Authors: Caria Sara
Published: November 2017

Oil has been Ecuador’s most important export product since the 70’s; the current low prices of commodities have placed the need of a productive diversification in the center of the debate about development strategies. In this paper, it is aimed at establishing whether the dependence on oil’s exports has been an obstacle for the diversification of Ecuadorian economy during the recent commodities boom (2003-2014), as the «product trap» thesis suggests. For this purpose, a survey on the literature about the so called «resources’ curse» will be made in order to identify the main rationales that support this thesis and the policy recommendations that literature on this topic suggests to oil-rich countries. Then, the Ecuadorian case will be analyzed to search evidence that confirm the existence of an «oil curse» in Ecuador. The results show that oil dependence and low diversification are empirically associated, but no clear causal relation can be established between them.

Authors: Endah Sukmawati Nur
Published: November 2017

Image retrieval can be divided into two types context-based and the content-based. Image retrieval based on the content refers to the image features such as color, texture, shape, semantics or sensations. This paper addresses the content-base image retrieval system based on expression sensitivity. It can be image or text query for input the system. Based on Itten theory, expression sensitivity consist of warm, cold, relax, anxious, and life. The research system uses two fuzzy inference system. Firstly, fuzzy inference system is used to decide image region of color. The image size is 256 x 256 pixel. Output the first fuzzy inference system is input for the second fuzzy inference system. The second fuzzy inference system is used to determined expression sensitivity of image. Degree of accuracy based on respondent from 50 images and 20 respondents is 42% for text query and 55% for image query. The further research, it can be used for other image such as medical image with certain criteria.
PARTICLE FILTER-BASED OBJECT TRACKING USING JOINT FEATURES OF COLOR AND LOCAL BINARY PATTERN HISTOGRAM FOURIER
Authors: Wiharta Dewa Made
Published: November 2017

Object tracking is defined as the problem of estimating object location in image sequences. In general, the problems of object tracking in real time and complex environtment are affected by many uncertainty. In this research we use a sequensial Monte Carlo method, known as particle filter, to build an object tracking algorithm. Particle filter, due to its multiple hypotheses, is known to be a robust method in object tracking task. The performances of particle filter is defined by how the particles distributed. The role of distribution is regulated by the system model being used. In this research, a modified system model is proposed to manage particles distribution to achieve better performance. Object representation also plays important role in object tracking. In this research, we combine color histogram and texture from Local Binary Pattern Histogram Fourier (LBPHF) operator as feature in object tracking. Our experiments show that the proposed system model delivers a more robust tracking task, especially for objects with sudden changes in speed and direction. The proposed joint feature is able to capture object with changing shape and has better accuracy than single feature of color or joint color texture from other LBP variants.

Authors: Widiartha I Made
Published: November 2017

Gamelan bali is one aspect of the art highly favored by both domestik and foreign tourists. One type of popular typical Balinese gamelan is Rindik. Rindik is one of Balinese traditional musical instrument made of bamboo. Now days, the number of foreign culture and today’s lifestyle give some impacts on the declining interest of Balinese to interact with this type of conventional gamelan. The younger generation is now more inclined to like devices which are played through electronics/software component. To increase public interest towards traditional gamelan bali especially rindik we need a breakthrough to digitize gamelan rindik and presenting it in the form of rindik software application. Today's advanced technology has made a way to digitize a wide range of instruments including rindik into computerized form. For example we can use frequency modulation as a voice synthesis technique. This method was developed by researchers in the field of sound synthesis. In this research, we have done the sound synthesis process of rindik instrument into digital form using frequency modulation. The best results were obtained through the synthesis comparison of carrier signal frequency and modulator is 1:7. Outcomes of this research is a digitizing result which is  presented in the form of a gamelan rindik package on desktop based software application.

Authors: Puspasari Shinta , Astuti Lastri Widya
Published: November 2017

This study proposes an approach to enhance image quality of power meter (KWH meter) using a color space transformation. Power meter is used to measure the power consumption of the customer. The amount of usage can be seen by looking at the character of numbers as indicators of measurement. Billing can be done automatically using character recognizer on imaging device by applying digital image processing techniques. Acquired image of the power meter may have poor quality because data acquisition process is very sensitive to light and noise. Appliance power meter is covered with glass that can reflect light, so that the quality of the acquired image varies depends on the lighting conditions at the time of acquisition. Color space transformation widen the color contrast of KWH meter image. The performance of the proposed approach is evaluated using a data set of KWH meter images of Smart Meter Indonesia models contains 30 RGB color model images. Before performs the proposed method, segmentation effectivesess is 93%. The experimental results shows an improvement of image quality that affect the character segmentation results up to 97%. Color space transformation is proven effective for the improvement of image quality and segmentation of KWH meter.

Published: November 2017

Introduction: Non invasive assessment of esophageal varices may improve the management and lower the medical and financial burden related to the screening. In this study, Our aim was to validate the prediction of varices using platelet count/spleen diameter ratio and Alanine transaminase/platelet ratio index (APRI).Methods: Fifty patients with newly diagnosed and treatment naive cirrhosis underwent screening endoscopy along with hematological and ultrsonographic studies. Platelet count/spleen diameter ratio and APRI index were assessed and their diagnostic accuracy calculated. Based on previous studies, a cutoff of 909 was applied for platelet count/spleen diameter ratio and cutoff of > 1.3 for APRI. The diagnostic accuracy of both the indices were further evaluated for severity and size of varices.Results: Prevalence of varices was 36% out of which 24% were large varices. Platelet count/spleen size diameter, portal vein diameter and APRI index had significant association for prediction of presence of varices and strongly correlated with size of varices. Platelet count/spleen size diameter of 909 had diagnostic accuracy of 80.5% for prediction of varices with diagnostic accuracy being 95.8 for predicting large varices. APRI index of more than 1.3 had accuracy of 75% for predicting varices and 87.5% for accurately predicting them as large varices.Conclusions: In a resource limited country like ours, where access to specialized and tertiary care hospitals and availability of endoscopy facilities in rural areas is an issue, these non invasive parameters platelet count/spleen diameter and APRI can be taken as a safe and reliable predictor for esophageal varices.Journal of Advances in Internal Medicine 2017;06(02):21-26.

Palliative Care and Hospice: A Paradigm for End-of-Life Care in Developing Nations
Authors: Clark Peter A.
Published: November 2017

Traditionally, medical care has had two mutually exclusive goals: either to cure disease and to prolong life or to provide comfort care. Given this dichotomy, the decision to focus on reducing suffering is made usually only after life-prolonging treatment has been ineffectual and death is imminent, usually by days or hours. As a result, one of the best kept secrets in a hospital today in the United States is palliative care and hospice care. We estimate that of the 2.4 million Americans that die each year, about 80% end their lives in hospitals attached to the latest advances in technology; 300,000 die at home under hospice care. The reasons why more people do not receive palliative or hospice care range from the patient’s fear of abandonment and the unknown, the family’s denial of the inevitability of death of their loved one, and physician’s denial of medicine’s limitations. Unless the options of palliative or hospice care are given to patients the fears that people have of dying--fear of dying alone and fear of dying in pain--will continue to make the dying process one that lacks dignity and respect. In this review article we have reviewed the state of palliative and hospice care in the United States through a historical, ethical and legal perspective. We have discussed its scope in the developing world and the potential challenges.Journal of Advances in Internal Medicine 2017;06(02):38-44.

Experimental and Numerical Investigation of the Recrystallization on a Sheet of Wrought Aluminum Alloy Al 6061
Authors: Mohajer-Irvani Y. , Scheck R. , Willer D. , Soppa E. A.
Published: November 2017

Apart from temperature and time, the deformation introduced in the material is another important parameter that affects the recryristallization process in metallic materials. The present study aims at examining the impact of the introduced deformation on recystallization and grain growth in Al 6061 alloy sheet. The deformation was introduced by hardness indentations in accordance with the Brinell test method applying two different loads. The samples with the hardness indentations were cut in half along the line on which the indentations were performed. One half served as sample providing a reference condition, while the other half was recrystallized. The grain size and the degree of misorientation (Kernel Average Misorientation, KAM) of the two neighboring measurement points were evaluated in both halves of the samples. Using the FE method, the hardness measurement procedure could be numerically simulated and the deformations which occurred beneath the hardness indentations could be evaluated and associated with experimental findings related to the grain size and the misorientation.
An Agrocentric Analysis of Regional Rain Patterns as They Relate to a Rained Cotton Cropping System on the Southern High Plains of Texas
Authors: Mahan James , Payton Paxton
Published: November 2017

Rain is the major limiter of cotton yields on the Southern High Plains of Texas. Rain can be analyzed in terms of its effect on the crop. An “agro-centric rain” analysis assesses the amounts and timing of rain events within a defined management system. Cotton on the Southern High Plains of Texas at Lubbock, TX, USA was analyzed in terms of the crop water environment associated with 70 potential cotton crop seasons over the period from 2006 to 2015. For the 10-year period, the 238-day cotton growing season was divided into seven potential cotton crop seasons of 154-days each. Rain and crop water status (as reference and crop evapotranspiration) were calculated for each of the 70 potential cotton crop seasons. The highest rain amounts were associated with earlier plantings. Maximum values of reference evapotranspiration were associated with the mid-season plantings and minimum values with the earliest and latest plantings. Crop stress (rain-reference evapotranspiration) showed a pattern with maximum stress associated with the earliest plantings. Crop water status across potential cotton crop seasons can vary with planting date across years and it may be possible to exploit the variation to improve yield in terms of germplasm and management practices.

Published: November 2017

This paper presents a compositional hierarchical model for pattern discovery in symbolic music. The model can be regarded as a deep architecture with a transparent structure. It can learn a set of repeated patterns within individual works or larger corpora in an unsupervised manner, relying on statistics of pattern occurrences, and robustly infer the learned patterns in new, unknown works. A learned model contains representations of patterns on different layers, from the simple short structures on lower layers to the longer and more complex music structures on higher layers. A pattern selection procedure can be used to extract the most frequent patterns from the model. We evaluate the model on the publicly available JKU Patterns Datasetsand compare the results to other approaches.

High-pressure gas is produced during the oil production process at offshore plants, and pressure relief devices, such as valves, are widely used to protect related systems from it. The high-pressure gas in the pipes connected to the flare head is burned at the flare stack, or, if it is nontoxic, is vented to the atmosphere. During this process, excessive noise is generated by the pressure relief valves that are used to quickly discharge the high-pressure gas to the atmosphere. This noise sometimes causes severe acoustic-induced vibration in the pipe wall. This study estimated the internal aerodynamic noise due to valve flow in a simple constriction-expansion pipe, by combining the large eddy simulation technique with a wavenumber-frequency analysis, which made it possible to decompose the fluctuating pressure into the incompressible hydrodynamic pressure and compressible acoustic pressure. First, the steady-state flow was numerically simulated, and the result was compared with a quasi-one-dimensional theoretical solution, which confirmed the validity of the current numerical method. Then, an unsteady simulation analysis was performed to predict the fluctuating pressure inside a pipe. Finally, the acoustic pressure modes in a pipe were extracted by applying the wavenumber-frequency transform to the total pressure field. The results showed that the acoustic pressure fluctuations in a pipe could be separated from the incompressible ones. This made it possible to obtain accurate information about the acoustic power, which could be used to assess the likelihood of a piping system failure due to acoustic-induced vibration, along with information about the acoustic power spectrum of each acoustic mode, which could be used to facilitate the systematic mitigation of the potential acoustic-induced vibration in piping systems.

Improving network security is a difficult problem that requires balancing several goals, such as defense cost and need for network efficiency, in order to achieve proper results. In this paper, we devise method of modeling network attack in a zero-sum multi-objective game and attempt to find the best defense against such an attack. We combined Pareto optimization and Q-learning methods to determine the most harmful attacks and consequently to find the best defense against those attacks. The results should help network administrators in search of a hands-on method of improving network security.

In a district cooling system (DCS), the distribution system (i.e., cooling water system or chilled water system) will continue to be a critical consideration because it substantially contributes to the total energy consumption. Thus, in this paper, a new distributed variable-frequency pump (DVFP) system with water storage (WS) for cooling water is adapted to a DCS with large end-use cooling load fluctuations. The basic principle and energy saving potential of the new system is analyzed. A case study of a DCS with a conventional central circulating pump (CCCP) system is presented to compare the energy consumption and the operating performance of CCCP and DVFP systems that are exposed to various weather conditions. The methods to perform this case study include, cooling load simulation and the modeling of two water distribution networks and systems via several commercial software packages. By replacing the throttling valves with a DVFP, the pump efficiency is increased and transportation energy consumption is reduced. Additionally, by introducing water tank storage, the cooling water is cooled at night and is released at a peak hour during the daytime, thereby further reducing the energy cost. As compared to the field test results of the CCCP system, the daily electrical energy saved by the DVFP and WS system is approximately 57% for a cooling water pump system on the hottest day in summer. This value also corresponds to approximately 10% of the energy saved for the entire system. Furthermore, additional energy could be saved under partial loading conditions.

The inherently intermittent and highly variable nature of wind necessitates the use of wind power forecasting tools in order to facilitate the integration of wind turbines in microgrids, among others. In this direction, the present paper describes the development of a short-term wind power forecasting model based on artificial neural network (ANN) clustering, which uses statistical feature parameters in the input vector, as well as an enhanced version of this approach that adjusts the ANN output with the probability of lower misclassification (PLM) method. Moreover, it employs the Monte Carlo simulation to represent the stochastic variation of wind power production and assess the impact of energy management decisions in a residential wind-battery microgrid using the proposed wind power forecasting models. The results indicate that there are significant benefits for the microgrid when compared to the naïve approach that is used for benchmarking purposes, while the PLM adjustment method provides further improvements in terms of forecasting accuracy.

Elasticity is one of the key features of cloud-hosted services built on virtualization technology. To utilize the elasticity of cloud environments, administrators should accurately capture the operational status of server systems, which changes constantly according to service requests incoming irregularly. However, it is difficult to detect and avoid in advance that operating services are falling into an undesirable state. In this paper, we focus on the management of server systems that include cloud systems, and propose a new method for detecting the sign of undesirable scenarios before the system becomes overloaded as a result of various causes. In this method, a measure that utilizes the fluctuation of the macroscopic operational state observed in the server system is introduced. The proposed measure has the property of drastically increasing before the server system is in an undesirable state. Using the proposed measure, we realize a function to detect that the server system is falling into an overload scenario, and we demonstrate its effectiveness through experiments.

Background: Discrimination is a common experience for Blacks across various developmental periods. Although much is known about the effect of discrimination on suicidal ideation of adults, less is known about the same association in Black youth. Aim: We examined the association between discrimination and suicidal ideation in a national sample of Black youth. We also explored gender and ethnic differences in this association. Methods: We used data from the National Survey of American Life-Adolescents (NSAL-A), 2003–2004. In total, 1170 Black adolescents entered the study. This number was composed of 810 African American and 360 Caribbean Black youth (aged 13 to 17 years). Demographic and socioeconomic factors were controls, perceived discrimination was the predictor, and lifetime suicidal ideation was the outcome. Logistic regression was used to test the association between perceived discrimination and suicidal ideation in the pooled sample, as well as based on ethnicity and gender. Results: In the pooled sample of Black youth, higher perceived discrimination was associated with higher odds of suicidal ideation (Odds Ratio (OR) = 1.09; 95% Confidence Interval (CI) = 1.02−1.17). This association was significant net of age, ethnicity, gender, and socioeconomic status. We did not find interactions between perceived discrimination and ethnicity or gender on suicidal ideation. Perceived discrimination was associated with suicidal ideation in African Americans (CI = 1.09; 95% CI = 1.01−1.17) and Caribbean Blacks (CI = 1.16; 95% CI = 1.03−1.32), males (CI = 1.11; 95% CI = 1.00−1.25), and females (CI = 1.08; 95% CI = 1.00−1.16). Conclusion: Discrimination jeopardizes the mental health of Black youth. In a universal pattern, discrimination is associated with suicidal ideation in Black youth. More research is needed on this topic.
