Authors: Chiesa Giacomo , Acquaviva Andrea , Grosso Mario , Bottaccioli Lorenzo , Floridia Maurizio , Pristeri Edoardo , Sanna Edoardo
Published: May 2019

Counterbalancing climate change is one of the biggest challenges for engineers around the world. One of the areas in which optimization techniques can be used to reduce energy needs, and with that the pollution derived from its production, is building design. With this study of a generic office located both in a northern country and in a temperate/Mediterranean site, we want to introduce a coding approach to dynamic energy simulation, able to suggest, from the early-design phases when the main building forms are defined, optimal configurations considering the energy needs for heating, cooling and lighting. Generally, early-design considerations of energy need reduction focus on the winter season only, in line with the current regulations; nevertheless a more holistic approach is needed to include other high consumption voices, e.g., for space cooling and lighting. The main considered design parameter is the WWR (window-to-wall ratio), even if further variables are considered in a set of parallel analyses (level of insulation, orientation, activation of low-cooling strategies including shading devices and ventilative cooling). Finally, the effect of different levels of occupancy was included in the analysis to regress results and compare the WWR with corresponding heating and cooling needs. This approach is adapted to Passivhaus design optimization, working on energy need minimisation acting on envelope design choices. The results demonstrate that it is essential to include, from the early-design configurations, a larger set of variables in order to optimize the expected energy needs on the basis of different aspects (cooling, heating, lighting, design choices). Coding is performed using Python scripting, while dynamic energy simulations are based on EnergyPlus.

Authors: Dai Min , Zhang Ziwei , Giret Adriana , Salido Miguel A.
Published: May 2019

Nowadays, the manufacturing industry faces the challenge of reducing energy consumption and the associated environmental impacts. Production scheduling is an effective approach for energy-savings management. During the entire workshop production process, both the processing and transportation operations consume large amounts of energy. To reduce energy consumption, an energy-efficient job-shop scheduling problem (EJSP) with transportation constraints was proposed in this paper. First, a mixed-integer programming model was established to minimize both the comprehensive energy consumption and makespan in the EJSP. Then, an enhanced estimation of distribution algorithm (EEDA) was developed to solve the problem. In the proposed algorithm, an estimation of distribution algorithm was employed to perform the global search and an improved simulated annealing algorithm was designed to perform the local search. Finally, numerical experiments were implemented to analyze the performance of the EEDA. The results showed that the EEDA is a promising approach and that it can solve EJSP effectively and efficiently.
Linking Biophysical and Economic Assessments of Ecosystem Services for a Social–Ecological Approach to Conservation Planning: Application in a Biosphere Reserve (Biscay, Spain)

Published: May 2019

The search for a balance between nature conservation and sustainable development remains a scientific and spatial planning challenge. In social-ecological systems based on traditional rural activities and associated with protected areas, this balance is particularly complex. Quantifying the economic impact of land use changes on ecosystem services can be useful to advise policy makers and improving social-ecological sustainability. In this study, we evaluated the land use changes in a time series and estimated the monetary value of the ecosystem services of the Urdaibai Biosphere Reserve (Biscay, Spain). In addition, we linked the monetary and biophysical values of land uses in each zoning units of the reserve, in order to identify the spatial adjustment between both assessments. Results showed that land use changes have clearly homogenized the landscape without substantially affecting its economic value. The methodological approach allowed detection that the reserve zoning was performed based more on its biophysical values than on economic ones. Thus, evident divergences between the biophysical and economic assessments were found. The core area was the one that had the highest coincidences (medium values) between both ecosystem services assessments, which highlights its importance not only in biophysical terms, is also economical. The procedure followed proved to be a useful tool to social-ecological planning and design of specific conservation strategies for the sustainable development of the area.
Application of a Hybrid Model Based on Echo State Network and Improved Particle Swarm Optimization in PM2.5 Concentration Forecasting: A Case Study of Beijing, China
Authors: Xu Xinghan , Ren Weijie
Published: May 2019

With the acceleration of urbanization, there is an increasing trend of heavy pollution. PM2.5, also known as fine particulate matter, refers to particles in the atmosphere with a diameter of less than or equal to 2.5 microns. PM2.5 has a serious impact on human life, a sustainable city, national economic development, and so on. How to forecast the PM2.5 concentration accurately, and then formulate a scientific air pollution prevention and monitoring program is of great significance. This paper proposes a hybrid model based on echo state network (ESN) and an improved particle swarm optimization (IPSO) algorithm for the Beijing air pollution problem, and provides a method for PM2.5 concentration forecasting. Firstly, the PSO algorithm is improved to speed up the search performance. Secondly, the optimal subset of the original data is selected by the convergence cross-mapping (CCM) method. Thirdly, the phase space reconstruction (PSR) process is combined with the forecasting model, and some parameters are optimized by the IPSO. Finally, the optimal variable subset is used to predict PM2.5 concentration. The 11-dimensional air quality data in Beijing from January 1 to December 31, 2016 are analyzed by the proposed method. The experimental results show that the hybrid method is superior to other comparative models in several evaluation indicators, both in one-step and multi-step forecasting of PM2.5 time series. The hybrid model has good application prospects in air quality forecasting and monitoring.
Occurrence of Micropollutants in Wastewater and Evaluation of Their Removal Efficiency in Treatment Trains: The Influence of the Adopted Sampling Mode
Authors: Verlicchi Paola , Ghirardini Andrea
Published: May 2019

The monitoring of micropollutants in water compartments, in particular pharmaceuticals and personal care products, has become an issue of increasing concern over the last decade. Their occurrence in surface and groundwater, raw wastewater and treated effluents, along with the removal efficiency achieved by different technologies, have been the subjects of many studies published recently. The concentrations of these contaminants may vary widely over a given time period (day, week, month, or year). In this context, this paper investigates the average concentration and removal efficiency obtained by adopting four different sampling modes: grab sampling, 24-h time proportional, flow proportional and volume proportional composite sampling. This analysis is carried out by considering three ideal micropollutants presenting different concentration curves versus time (day). It compares the percentage deviations between the ideal concentration (and removal efficiencies) and the differently measured concentrations (removal efficiencies) and provides hints as to the best sampling mode to adopt when planning a monitoring campaign depending on the substances under study. It concludes that the flow proportional composite sampling mode is, in general, the approach which leads to the most reliable measurement of concentrations and removal efficiencies even though, in specific cases, the other modes can also be correctly adopted.
Ride Blending Control for Electric Vehicles

Published: May 2019

Vehicles equipped with in-wheel motors (IWMs) feature advanced control functions that allow for enhanced vehicle dynamics and stability. However, these improvements occur to the detriment of ride comfort due to the increased unsprung mass. This study investigates the driving comfort enhancement in electric vehicles that can be achieved through blended control of IWMs and active suspensions (ASs). The term “ride blending”, coined in a previous authors’ work and herein retained, is proposed by analogy with the brake blending to identify the blended action of IWMs and ASs. In the present work, the superior performance of the ride blending control is demonstrated against several driving manoeuvres typically used for the evaluation of the ride quality. The effectiveness of the proposed ride blending control is confirmed by the improved key performance indexes associated with driving comfort and active safety. The simulation results refer to the comparison of the conventional sport utility vehicle (SUV) equipped with a passive suspension system and its electric version provided with ride blending control. The simulation analysis is conducted with an experimentally validated vehicle model in CarMaker® and MATLAB/Simulink co-simulation environment including high-fidelity vehicle subsystems models.

Tinjauan Teologis Konsep Iman dan Perbuatan Bagi Keselamatan
Authors: Handayani Dessy
Published: May 2019

The conflict between faith and actual action is caused by the ignorance of many people for grace and the law. The view that ‘faith is not enough' or 'faith must be parallel to deed' has completely ignored what the Word of God says about both. In this paper the author shows the standard of the Word of God to understand faith and deed takes place in the life of true Christianity. The life of faith must depart from faith and lead to faith, meaning we must live by faith. Faith is expressed through deeds. So, Faith and Actions are two things that can not be separated from each other, but complement each other. Salvation is the grace of God and Man can only accept salvation from God only through faith, not by works. Having received salvation in this way, man must work the salvation in life through the deeds that men do and do. If man is not active in salvation in this way after he becomes a believer, it shows that the faith he claims to be by mouth is dead faith. It's a sign that he has not really experienced salvation. Man is not saved by works. But deeds are a sign of whether the faith really lives. James does not intend to distinguish between faith and deeds; what is distinguished is between faith accompanied by deeds and faith which is not accompanied by deeds. For James faith must be accompanied by deeds. One can not exist without the other, for faith without works is dead.

This article discusses the eschatology (end times) in the perspective of the Gospel of Mark. This topic is not contained in the other chapters in the book of Mark, rather than just in Mark 13: 1-37. Mark 13: 1-37 , featuring a view of the history in which the crisis and persecution at this age will pave the way for a future. It draws from the passage is an introduction to the understanding of eschatology, beginning with the statement of a disciple of Jesus about the temple (13:1) and the response of the Lord Jesus spoke of the events still in the future (eschatology) and at the same time talking about events imminent (the collapse of the temple). Both events are discussed simultaneously, as if the two events occur at the same time. In this paper, the two events referred to as a dual prophecy of the Lord Jesus. In Mark 13, the Lord Jesus spoke of the end of world history has begun. The period between the sufferings and death of Jesus until His coming the second time is the final phase of the history of the old times, before the start of a new era that is, when the Son of Man comes in all his glory. The phase between the two ages was marked by signs or events, both general and specific nature

In
today's world of increasing international trade, companies are suggested to
learn, implement and maintain new production techniques in place of traditional
production systems in order to sustain their assets. In this approach, we have
worked on “Six Sigma”, one of the strongest components of these so-called
systems. Within the scope of this study, Six Sigma and its application areas
are investigated, and as a result of the obtained findings, six sigma
applications have been made in the textile industry where the quality is
desired to be improved. In the study, conducted by following the six sigma's
DMAIC (Define, Measure, Analyse, Improve, Control) steps, using the detection
tools such as SIPOC (Suppliers, Inputs, Process, Outputs, Customers) diagrams,
measurement systems analysis, root cause analysis, determination of poor
quality sources and improvement on the basic problem have been made. The
variation of the strips from the card and cer machines in the plant created
great quality problems. Before the six sigma project, the average coefficient
of variation value of the card machines was 2.02. With this project, the
average coefficient of  variation value
of the card machines is aimed to be reduced to 0.5-1.5 range. After the six
sigma project, the average voefficient of variation value of the card machines
was reduced to 1.03.

Published: May 2019

The localization of fruit trees, the topology of the branch structure and the spatial structure of the canopy are important to plan sitespecific agro-ecological and production technology projects in an orchard. The currently used instruments and technologies – in the precision agriculture – give opportunities to obtain these informations. The examinations were carried out in the Study and Regional Research Farm of the University of Debrecen near Pallag with the use of a GreenSeeker 505 Hand Held™ Optical Sensor Unit, and its interface the Trimble AgGPS FmX Integrated Display board computer. The collected spectral data were completed with the 3D point cloud by Leica ScanStation C10 laser scanner. The laser impulse data and the vegetation index values were integrated in a unified 3D system. The integration of the two special data collection system provides new opportunities in the development of precision production technology system. The results could be directly used in phytotechnology, water management, plant protection and harvesting in orchards. Our elaborated method can supply digital high spatial accuracy guidance data for development of the automated machines, which could provide some new developmental way in the immediate future.
Effect of cultivation factors on the yield and yield security of maize
Authors: Mihály Sárvári
Published: May 2019

Cultivation factors have a significant effect on the yield and yield security of maize. Ensuring a suitable green crop is important. Tricultural crop rotation (pea–wheat–maize) in the average of 25 years provided a 2 t ha-1 higher yield compared to monocultural cultivation. A harmonious NPK nutriment supply determines yield and yield security, which can be especially realized by means of the application of precision cultivation technologies. Under average circumstances N 80 kg ha-1, P2O5 50 kg ha-1, K20 60 kg ha-1 active ingredient is the agro-ecological dosage of artificial fertilizer.Plant density is a factor that determines yield. Optimal plant density – beside the genetic characteristics of the hybrid – is mostly influenced by the level of water and nutriment supply.

Using the principles of precision animal husbandry in fishbreeding
Authors: László Stündl  , Milán Ferhér  , Péter Bársony
Published: May 2019

Aquaculture species such as fish, crayfish, molluscs and plats are a wide range of products, with continuously growing demand worldwide. The reasons for this is that they are cheap and easy-toraise protein sources, thus having significance in food supply especially in developing countries in tropic regions, moreover, the premium category foodstuffs in developed high income countries are also belonging to this category. World annual total production of 164 million tons (2009) are made up of two sources: 1) marine and inland fisheries landings that are stagnating for several years and 2) aquaculture which is growing dynamically with annual 6% rate between 2000–2009. The latter is accounting for nearly 45% of the total supply due to the depleting marine stocks caused by overfishing. Aquaculture is growing continuously also because the production is safe and canbe planned well. Intensive fish production systems are the representatives of precision animal production, several types exist and widespread worldwide. The modern computerized temperate water recirculation plants with several thousand m3 capacity are widespread also in Europe because they make it possible to produce even the most valuable species whole year round. A key issue in the technical/feeding outlay is to meet the demands of the cultured species the best and the operation of the system is to be safe and cost-effective. One condition for this is intensification: enable to produce more product per unit resource input or effort. The facilities need significant amount of energy, thus renewable energy sources are to be favoured for which Hungary has comparative advantages.
Economic questions of precision maize production on chernozem soil
Authors: Dénes Sulyok
Published: May 2019

It is one of the main topical objective to establish the conditions of sustainable farming. The sustainable development in crop production also calls for the harmony of satisfying human needs and providing the protection of environmental and natural resources; therefore, the maximum consideratio of production site endowments, the common implementation of production needs and environmental protection aims, the minimum load on the environment and economicalness. Precision farmin encompasses the farming method which is adjusted to the given production site, the changing  technology in a given plot, the integrated crop protection, cutting edge technologies, remote sensing, GIS, geostatistics, the changeof the mechanisation of crop production, and the application of information technology novelties in crop production. Modern technology increases efficiency and reduces costs. The efficiency of crop production increases by reducing losses and the farmer has access to a better decision support information technology system. In addition, we consider it necessary to examine the two currently most important economic issues: “is it worth it?” and “how much does it cost?”. During the analysis of agricultural technologies, we used the precision crop production experiment database of KITE Zrt. and the Institute for Land Utilisation, Regional Development and Technology of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen.During our analytical work, we examined three technological alternatives on two soil types (chernozem and meadow). The first technology is the currently used autumn ploughing cultivation. We extended our analyses to the economic evaluation of satellite navigationassisted ploughing and strip till systems which prefer moisture saving. On chernozem soil, of the satellite-based technological alternatives, the autumn ploughing cultivation provided higher income than strip till. In years with average precipitation supply, we recommend the precision autumn ploughing technological alternative on chernozem soils in the future. On meadow soil, the strip till cultivation technology has more favourable economical results than the autumn ploughing. On soils with high plasticity – considering the high time and energy demand of cultivation and the short amoung of time available for cultivation – we recommend to use strip till technologies.
The role of the hybrid-specific technological recommendations of maize in precision crop production procedures
Authors: Endre Széll  , Máté Makra
Published: May 2019

The necessity of application of hybrid specific crop production technology has been confirmed not only by trial results but also by the experiences gained from the agricultural practice. For this reason it is essential to test and collect data in field trials about the specific agronomic traits of the corn hybrids belonging to different maturity groups and genotypes. Corn hybrids are tested for their responses to sowing time, plant density and fertilizer supply; sensitivity to herbicides; and lately, the resistance to the damages caused by the larvae of corn root worm. Last but not least, mention should be made of the differences in the responses of the corn hybrids to the damages caused by drought stress. Based on the trial results, suggestions for the hybrid specific corn production are compiled and made public for the experts and farmers engaged in corn growing. Corn hybrids may deliver maximum yields on the impact of specific crop production technology only in case if it relies on carefully done general production technology including soil cultivation, seed bed preparation and weed control. Similarly, precision crop production technology may advance the yield increase in economic way if it is constantly drawing on the source of research results.
Soil – Environment – Sustainability
Authors: György Várallyay
Published: May 2019

The future and life quality of human society depends primarily on the success of the sustainable use of natural resources: the geological strata–soil–water–biota–near surface atmosphere continuum. Soil is the most significant conditionally renewable natural resource in our Earth’s system, with three unique properties: multifunctionality; fertility/ productivity; resilience. In the case of rational land use and precise soil management soil does not disappear, and its desirable „quality” does not decrease considerably, irreversibly and unavoidably. Its renewal, however, requires continuous care and permanent activities.Consequently, the prevention, elimination or moderation of soil degradation processes and extreme hydrological situations (the two main factors limiting desirable soil multifunctionality) with rational land use and soil management are the key factors and priority tasks of sustainable development on each level and in each phase of the decisionmaking process.

The aim of the article is to study the interaction effect between NAA and BAP concentration on protocorm growth and to know the proper concentration for growth of Dendrobium  spectabile  orchid protocorm. This research method using an experimental method which is conducted in the Laboratory of Agriculture Faculty of Winaya Mukti University, Tanjungsari Subdistrict, Sumedang District. The experiment was conducted from June 2017 until September 2017. The experiment used was a Completely Randomized Design (CRD) with the factorial pattern, consisting of two factors and repeated twice. the first factor was the effect of NAA concentration which consisted of five levels, namely without NAA, 0.5 mg kg-1, 1.0 mg kg-1, 1.5 mg kg-1, and 2.0 mg kg-1.  The second factor is the BAP concentration which consists of five levels, namel without BAP, 1.0 mg kg-1, 2.0 mg kg-1, 3.0 mg kg-1, and 4.0 mg kg-1. Eksplant is protocorm from orchid D. spectabile which is grown on MS medium (Murashig and Skoog) half recipe as base medium accompanied by each treatment for 12 weeks. The experimental results show that there is an interaction between the effect of NAA and BAP concentration on the number of leaves only. Without NAA or 1.5 mg kg-1 NAA concentration with BAP 2.0 mg kg-1 gives more leaves.  Independent of NAA or BAP concentrations did not affect the number of buds, number of roots, root length, fresh and dry weight of plantlets, and also growth ability of plantlets.  BAP concentration only affect plant height, and the highest plantlet height is found without add of BAP in medium culture

Each type of forest ecosystem and the species in it have different abilities to absorb CO2 and produce biomass. Coffee-based agroforestry is thought to be able to increase the ability of forests to store carbon as a result of increasing species composition and density of plants in these forest areas. This study aims to determine the composition of plants and carbon stocks stored in coffee-based agroforestry forests in LMDH Paniis RPH Rancakalong BKPH East Manglayang KPH Sumedang Perum Perhutani Regional Division West Java and Banten. This study uses survey and laboratory methods. Data collection is done by collecting data directly at the research location, which is in the agroforestry forest area and natural forest area (as a comparison). Data obtained through observations in the field and laboratory are in the form of tree names, wood density, tree biomass and carbon stocks from biomass. The result shows that the agroforestry forest composition at LMDH Paniis RPH Rancakalong BKPH East Manglayang KPH Sumedang within 17,14 ha consists of Pine (Pinus mercusii), Big-leaf Mahogany (Swietenia macrophylla), Clove (Syzygium aromaticum) dan Coffee (Coffea arabica). The carbon stock is 1.869,73 kg/ha in agroforestry forest, 2.618,32 kg/ha in primary natural forest, and 1.460,91 kg/ha in secondary natural forest. Agroforestry forest has more carbon stock than the secondary natural forest, but agroforestry forest has less carbon stock than primary natural forest.

The second factor is Form Cutting (S) consisting of 3 levels of treatment, is the oblique sliced (s1), taper sliced (s2), and flat sliced (s3). The factors composed of nine combinations of treatments, each of which was repeated 3 times. The results show that was not the interaction between the shape of cuttings and Root-up applications on the growth response variables of cutting rose plants, is number of shoots, length of shoots, root length, number of roots, and root volume. The oblique sliced and tapered slice form the base and of the cutting shave the best effect on the length of shoots of rose plants cutting
Hacia una indagación de la vertiente subjetiva de los imaginarios sociales. Aportes desde la obra de Cornelius Castoriadis
Authors: Rosso Germán
Published: May 2019

Una de las referencias centrales en el incipiente campo de investigación de los imaginarios sociales es indudablemente Cornelius Castoriadis. Entre sus aportes se destaca la formulación de una noción tan importante como la de significaciones imaginarias sociales. Sin embargo, puede detectarse cierta vacancia en el abordaje de lo que el autor comprendió como su vertiente subjetiva. En este trabajo se propone recuperar dicho problema para reflexionar acerca del modo en que la subjetividad adhiere a los imaginarios políticos y sociales. Se contrastan dos niveles distintos de comprensión en cuanto a la vertiente subjetiva de las significaciones imaginarias, uno referido al tipo antropológico como un conjunto de rasgos psicológicos y comportamentales y otro pertinente a los procesos psicogenéticos y sublimatorios que permiten al sujeto reasumir la realidad social. Recuperando estos elementos se puede poner de relieve la importancia de la noción de tipo antropológico en un sentido lo suficientemente amplio como para permitir dar cuenta de las distintas vertientes subjetivas en su conjunto, abarcando así los dos niveles de comprensión del problema.

El artículo que nos ocupa presenta una iniciativa que busca facilitar la autoevaluación y el monitoreo de los proyectos de incorporación de tic en educación por parte de los propios responsables de su diseño (docentes, directores, supervisores). A tal fin, fue diseñado un sitio web en el cual se ponen a disposición los siguientes materiales: a) una selección de documentos y bibliografía vinculados a la evaluación de proyectos tic; b) guías y orientaciones metodológicas, y c) instrumentos para la autoevaluación de los proyectos tic (encuestas, pautas para entrevistas y pautas para grupos focales, entre otros). A su vez, el desarrollo contempla un diagnóstico que cada institución puede realizar inicialmente y recuperar con posterioridad para reflexionar acerca del grado de avance alcanzado.
Licenciados PROUNI: dificuldades no percurso acadêmico e resultados da formação
Authors: Felicetti Vera Lucia
Published: May 2019

Uma das metas do Plano Nacional de Educação é investir na formação docente. O Programa Universidade para Todos – Prouni – incentiva e investe na formação de nível superior para professores atuantes na educação básica, bem como para alunos egressos do ensino médio. Este trabalho teve por objetivo analisar as dificuldades encontradas no percurso acadêmico por licenciados Prouni, perceber como esses egressos sentem-se em relação à formação acadêmica, e identificar se estão atuando na área de formação. A metodologia usada teve enfoque qualitativo com análise textual discursiva. Entre os resultados apresentados apontam-se as dificuldades encontradas pelos estudantes durante o percurso acadêmico, tais como recursos financeiros, associar trabalho com os estudos, falta de tempo para se dedicar mais aos estudos, e a adaptação na universidade. Os resultados encontrados também indicam a satisfação do egresso em estar graduado e o incentivo que esses graduados exercem no núcleo familiar e na sociedade acerca da formação acadêmica conquistada. Evidencia-se, também, a necessidade de estudos em âmbito maior, que permitam entender como estão os licenciados no mercado de trabalho e o porquê da não atuação de muitos deles na área de formação, ou seja, como docentes. Com estudos mais abrangentes, envolvendo análises quantitativas, será possível avaliar melhor e verificar como estão os graduados dos cursos voltados para a carreira do magistério e se o investimento do Prouni em relação ao magistério está correspondendo às expectativas do Plano Nacional de Educação.
