Virtual Park‐based control strategy for grid‐connected inverter interfaced renewable energy sources
Authors: Çelik Doğan , Meral Mehmet Emin , Inci Mustafa
Published: August 2019

Unbalanced grid faults are the most severe perturbations which degrade the performance of grid‐connected inverter interfaced renewable energy sources (IIRESs). In this regard, this study proposes a novel control strategy that provides optimum use of the power capability of the grid‐connected IIRES under unbalanced grid fault conditions. One of the major contributions to previous methods is to propose a fast and robust improved Virtual Park (VP) sequence extractor to implement the reference current generator (RCG). The dynamic response of the grid‐connected IIRES has also enhanced thanks to the proposed VP sequence extractor. The computing of maximum active power injection and simultaneously amplitude of phase currents is embedded into a new algorithm based the RCG to meet the aimed control objectives. The controllability and minimisation of active and reactive power oscillations are also formulated and carried out with only one control parameter. Another contribution of this study is to prevent overcurrent issues with peak current limitation control. Reference for active power is online computed based on the maximum current injection at inverter capacity for overcurrent protection. The validating effectiveness of the proposed solution is performed by a comprehensive set of cases to show the shortcomings of previous similar studies.
Reduce deposits on heat exchange surfaces when burning inferior coal
Authors: Bică Marin , Stoian Andrei , Tutunea Dragoş , Călbureanu Mădălina
Published: August 2019

The phenomenon of soiling of heat exchange surfaces occurs in all types of combustion plants. The deposit of solids (combustion gases particles) worsens heat transfer by reducing combustion efficiency, increasing fuel consumption and pollution. Deposits are influenced by combustion temperature, gas flow rate, dimensions of solids drift by combustion gases as well as the composition of fuel mixtures used (eg inferior coal with flame retardant gas or tar fuel). In the present paper are presented techniques and methods adopted for the reduction of soiling of the heat exchange surfaces and the results obtained on high energy power plants (steam boilers).

Published: August 2019

The current paper presents the processes of data acquisition and air temperature monitoring in the key points of a hot air generator working on the TLUD principle, which uses temperature sensors, a data acquisition board and an application developed in LabView that numerically and graphically displays temperature variation during burning. The results of the monitoring were obtained on an experimental model, developed by research scientists at INOE 2000-IHP. The data acquired is then used to establish the algorithm for opening the air supply valves for gasification and combustion air, in order to optimize combustion by maintaining the optimum temperature at the funnel.

Published: August 2019

The operation of an air-to-water heat pump system providing space heating production for an administrative building in Varna has been explored. For this purpose, discontinuous operational mode of the heat pump system during wintertime is considered. Study has been performed by use of real values for external ambient temperature and operating characteristics of the heat pump system. The seasonal efficiency of the heat pump operation has been calculated. Also, the minimal external ambient temperature until the heat pump may work in heating regime and operation duration at outdoor air temperatures higher than the design air temperature can be determined. The economic analysis of the heat pump system exploitation has been made finally.

Authors: Purece Cristian , Panaitescu Valeriu , Chera Anghel Irina Alina
Published: August 2019

The implementation of the requirements of the European Parliament Directive 2009/28 / EC requires efficient use of the water supply of a hydropower plants installation in order to obtain a higher amount of electricity by producing the same volume of water. In order to achieve efficient utilization of the energy of the water is necessary framing the operation of hydropower plants in the ranges of head course and the electric power so that the energy conversion is carried out in the optimum efficiency characteristic operation of the system. In order to determine as accurately the actual operating characteristics of a hydro-unit, in situ tests are required to determine the actual operating parameters of the hydro-unit. These parameters, the flow rate is the parameter that requires the most complex methodologies to determine. The paper presents a way of improvement but also a simplification of the methodology for in situ determination of the flow to small hydropower plants by using a mobile frame that has implemented a wireless data transmission system.

Authors: Cardei Petru , Muraru Sebastian , Matache Mihai
Published: August 2019

The article presents a possibility of applying the techniques specific to the drones (UAV) in order to estimate the efficiency, and optimize the windbreaks (vegetative barriers, forest curtains).In the first part the article presents a variant of determination of the dynamic and optical porosities of forest protection curtains using one or two drones simultaneously. In the second part, ascertaining some language inaccuracies, it observes that the issue of the efficiency of the forest curtains became a problem of mitigation of wind intensity. Finally, the last proposed application shows that using the drones, you can estimate the protected volumes behind the curtains, basically giving up the optical porosity. In order to achieve these applications, there is an essential condition: records of the magnitude of the wind speed and of the coordinates must not be excessively affected by the wind.

Authors: Manea Dragoş , Marin Eugen , Mateescu Marinela , Dumitraşcu Andrei
Published: August 2019

In this paper, sowing rate optimization of grassland drills consisted in finding an optimum combination between the seed flow of the seed metering device and the drill working speed, in order to achieve the sowing rates required by agro-technique for herbs seeds. It was developed a mathematical model that describes the seed flow variation depending on the working speed of the grassland drill and the active length of the groove cylinders. The experimental research was conducted using a grassland drill with eight metering devices and an automated installation, which simulates the working speed of the drill, collects and weighs seeds from each individual metering device. By using MathCad 14.0, it have been drawn the variation diagram of seed flow depending on active length of the groove and working speed. The comparative study of the variation diagrams based on experimental data and the variation diagrams obtained from mathematical modelling highlighted that the downward trend of the seed flow was observed in 66,67% of the results. Based on the mathematical model presented in this paper, it might be developed an algorithm enabling for fast obtain the optimal combination between the adjustment parameters, in order to apply a desired sowing rate.
Experimental results on the solid organic fertilizer machine MG 5
Authors: Ştefan Vasilica , Sfîru Raluca , Popa Lucreţia
Published: August 2019

This paper is the first of a series of works devoted to the general issues of organic fertilizer spreading machines. Although the working process of solid organic fertilizer machines does not contain a large number of random constituents, however, the basic component, the material administered, gives the random characteristic of the process. In addition, another random component that influences the working process of the machine is the interaction of the work organ that performs the tearing and distribution of the scattered material with this material, as well as the movement of the fragments of material onto the surface of the device. A third random component is the movement of the material scattered into the atmosphere. The fragments of scattered material exhibit shape irregularities due to fragments during dislocation from the mass of feed material and due to particle collisions while moving into air until the contact with the soil. Therefore, the phenomenon of spraying the organic fertilizer on the layer from the soil surface is, as a whole, a random process. Consequently, it is logical to have experimental research prioritized in the study of the work on the distribution of solid organic fertilizers. The role of this article is to present the experimental results, some conclusions and to prefigure several theoretical or theoretical-empirical research directions. The results contained in this article are basics in all the other essays related to the topic machine.
Cost structure – an important indicator of innovation activity in agro-industrial complex (by the example of crop production)
Authors: Voiku Ivan , Varlamov George
Published: August 2019

In agro-industrial complex, cost structure is of strategic importance, because it allows to determine the level of innovation activity. The study revealed diversified influence of the innovation factor (acceleration of scientific and technological progress) on the cost structure and, first of all, on the change in the ratio of share of direct labor and materialized labor in favor of the latter. Implementation of the achievements of scientific and technological progress in enterprise activities leads to a reduction in the cost of direct labor and, at the same time, to an increase in its value due to the growth of qualification requirements. Furthermore, the innovative development of enterprises assumes the implementation of intensive technologies and the acquisition of more productive equipment. In the research, all the main agricultural crops in the Pskov region (Russia) are divided into groups according to the share of direct labor and materialized labor. The effectiveness of innovative development is determined by:

ratio of the savings from reduction of direct labor costs to the effect from implementation of the innovations, which have affected this reduction;

ratio of the savings from reduction of material costs and energy costs to the effect from implementation of the expensive technological innovations, which have affected this reduction.

Published: August 2019

Depuis 2015, la métropole de Montpellier finance des actions de recherche et développement au travers de contrats de délégation de service public de l’assainissement. Un des projets a porté sur l’évaluation des actions de réduction à la source des micropolluants d’un établissement de soin, la Polyclinique Saint-Roch, engagé depuis 2013 dans une politique de développement durable, de réduction de ses impacts sur l’environnement, qui a fait l’objet d’un transfert dans un nouvel établissement en 2016. Veolia a lancé, dans ce contexte, une étude multipartenaire (Polyclinique Saint-Roch, UMR HydroSciences Montpellier, métropole de Montpellier et Veolia Eau), afin de caractériser les rejets d’assainissement de l’ancien et du nouvel établissement, ce dernier ayant mis en oeuvre de nouvelles pratiques pour diminuer ses rejets. Cette étude se décline en plusieurs actions : sélectionner au préalable des molécules susceptibles d’être représentatives de l’activité de soins, les quantifier dans les eaux usées, prédire les concentrations de molécules médicamenteuses représentatives (calcul d’un PEC : concentration prédite dans l’environnement) et les comparer aux valeurs mesurées. Le changement des pratiques a une répercussion significative sur la réduction des flux de micropolluants rejetés au réseau par la Polyclinique Saint-Roch, qui est suffisante pour ne pas engager de prétraitements sur leur site. La démarche est transposable aux autres établissements de soins de la métropole. La méthode de calcul des PEC dans les eaux usées est acceptable et intéressante pour un diagnostic préalable et/ou une approche globale des émissions.

Published: August 2019

Hintergrund Die begleitende Ernährungstherapie von Intensivpatienten stellt eine besondere Herausforderung in der klinischen Routine dar und erfordert die Implementation von leitlinienbasierten Handlungsanweisungen.

Methoden In einer retrospektiven Analyse wurde die Umsetzung der klinikinternen Handlungsanweisung zur Ernährung kritisch kranker Patienten (Gültigkeitszeitraum September 2013 bis Januar 2016) sowie der Anordnung zur Ernährungstherapie auf einer operativen Intensivstation des Universitätsklinikums Bonn an Daten des Ernährungsmanagements von 31 Langzeit-Intensivpatienten (7 Frauen; Alter: 60 ± 17 Jahre; BMI: 28 ± 10 kg/m2; Dauer des Intensivaufenthalts: 34 ± 16 Tage) evaluiert. Ausgewertet wurden Daten zur Initiation, zum Ablauf sowie zur Berechnung und Umsetzung der Energie- und Proteinzufuhr. Dazu wurden jeweils die im Stationsalltag angeordnete bzw. protokollierte Zufuhr, die protokollierte Zufuhr abzüglich Reflux sowie das retrospektiv beurteilte Ziel, welches durch die klinikinterne Handlungsanweisung indiziert war, miteinander verglichen (linear gemischtes Modell).

Ergebnisse Mit der enteralen Ernährung wurde im Mittel an Tag 4 ± 3, mit der (supplementierenden) parenteralen an Tag 3 ± 3 begonnen. Die Energiezufuhr wurde mit Korrekturfaktoren als ein Vielfaches des Grundumsatzes nach Harris & Benedict berechnet. Der individuell verwendete Korrekturfaktor zur Berechnung der angeordneten Energiezufuhr wich über die gesamte Dauer des stationären Aufenthalts 0,1 ± 0,3 vom retrospektiv als angemessen erachteten Korrekturfaktor ab. Hieraus resultierte eine Abweichung der angeordneten Energiezufuhr vom Energieziel von 123 ± 528 kcal/24 h. Insbesondere in den Tagen 1 – 10 betrug die Abweichung des angeordneten vom retrospektiv als angemessen erachteten Korrekturfaktor 0,2 ± 0,4, was zu einer Differenz zwischen angeordneter Energiezufuhr und Energieziel von 426 ± 772 kcal/24 h führte. Die protokollierte Proteinzufuhr lag über die gesamte Behandlungsdauer bei 1,1 g/kg KG/24 h, während das retrospektiv ermittelte Proteinziel 1,0 g/kg KG/24 h betrug.

Schlussfolgerung Die Analyse liefert vertrauenswürdige Daten zur Implementation einer individualisierten Ernährungstherapie von Langzeit-Intensivpatienten auf einer operativen Intensivstation; diese können zur Weiterentwicklung von entsprechenden Handlungsanweisungen genutzt werden. Defizite bestehen sowohl im zeitlichen Ablauf (zu später Beginn) als auch in der Anordnung der Energie-/Nährstoffzufuhr. Umfassende Schulungen des ärztlichen und pflegerischen Personals zur Anwendung/Umsetzung der Ernährungstherapie sind zu empfehlen.

Rupture of a Type B Aortic Dissection in a Postpartum Patient with Marfan Syndrome
Authors: Patberg Elizabeth , Duffy Jennifer , Hameed Afshan B.
Published: August 2019

Background Pregnant women with Marfan syndrome (MFS) are known to be at increased risk of aortic dissection; however, cases of aortic rupture are extremely rare. There is lack of consensus on the exact site and size of aortic diameter measurement that increases this risk, and whether this applies to both Type A and Type B dissections.

Case A 23-year-old G2P1001 with known Marfan syndrome who underwent an uncomplicated antepartum and intrapartum course. She experienced persistent backache 10 days postpartum that led to the diagnosis of Stanford Type B dissection. The patient was hospitalized for close observation. Dissection progressed to aortic rupture within 24 hours that required emergent thoracic endovascular aortic repair. She had an uncomplicated postoperative course.

Conclusion Our report demonstrates rupture of a known aortic dissection within a very short time in the postpartum period. The case highlights the importance of patient education and close surveillance especially in the postpartum period. It also brings home the value of imaging of the whole aorta rather than focusing on the ascending alone. Multidisciplinary care and timely diagnosis and intervention likely led to the favorable outcome in our case.

Published: August 2019

Contrast-enhanced ultrasound (CEUS) has been widely accepted as a diagnostic tool for the detection and evaluation of benign and malignant liver lesions and has been implemented into the clinical routine as a tool for percutaneous interventional real-time image guidance. CEUS can be combined with computed tomography (CT) and magnetic resonance imaging (MRI) datasets using real-time image fusion to additionally surveil proper interventional treatment and assess treatment success. This review describes the state-of-the-art use of CEUS for the surveillance and monitoring of interventional procedures of the liver and for the evaluation of postinterventional success.
Maternal Marijuana Exposure and Birth Weight: An Observational Study Surrounding Recreational Marijuana Legalization
Authors: Straub Heather L. , Mou Jin , Drennan Kathryn J. , Pflugeisen Bethann M.
Published: August 2019

Objective This study aimed to study the relationship between prenatal marijuana and infant birth weight using natural cohorts established before, during and after the 20-month lapse between legalization and legal recreational sales in Washington State.

Study Design Over 5 years, 5,343 pregnant women with documented urine drug screen (UDS) results delivered at Tacoma General Hospital or Good Samaritan Hospital. Maternal medical data were extracted for three delivery cohorts established based on before (T1), during (T2), and after legalization (T3) of recreational marijuana and legalized availability. Univariate and multivariate models were created to study marijuana exposure on infants' birth weight.

Results Marijuana exposure increased the risk of low birth weight (LBW; odds ratio [OR] = 1.42, 95% confidence interval [CI]: 1.01–2.01). This was more pronounced in full-term babies (OR = 1.72, 95% CI: 1.10–2.69), and was independently associated with a higher risk for small for gestational age (SGA; OR = 1.51, 95% CI: 1.49–1.53). The associations between marijuana exposure and SGA were maintained in cohort-specific models (OR = 1.53, 95% CI: 1.01–2.32 for T2, and OR = 1.43, 95% CI: 1.01–2.02 for T3, respectively).

Conclusion Marijuana exposure verified by UDS was associated with LBW and SGA. However, recreational marijuana legalization and availability did not have direct impact on newborns' risk of LBW or SGA.
Energy conservation during single droplet impact on deep liquid pool and jet formation
Authors: Hasegawa K. , Nara T.
Published: August 2019

This paper investigates the impact of single droplets impinged into a deep liquid pool at atmospheric pressure. The single-droplet dynamics of three impinging liquid samples with different surface tensions, viscosities, and densities were experimentally investigated. The time evolution from droplet impingement on the pool surface to jet formation was recorded by a high-speed video camera. The impact velocity and droplet diameter were varied as 1.0–3.2 m/s and 1.8–3.0 mm respectively, and the liquid-pool depth was fixed at 30 mm. The cavity volume was affected by the impact parameters, indicating a clear correlation between drop diameter and impact velocity. For the water droplets, the jet volume was decreased and increased under lower and higher impact velocity conditions, respectively. For ethanol droplets, the jet volume increased at higher impact velocity and larger droplet diameter. To gain deeper physical insight into the jet formation, the energy balance of droplet impingement onto the liquid pool surface was estimated. Approximately 28% of the impact energy was invested in cavity formation, regardless of the liquid properties. The remaining energy was most likely dissipated or consumed at the surface. All of the cavity energy in all samples was consumed in jet formation.
Resonant-tunneling-diode terahertz oscillator with a cylindrical cavity for high-frequency oscillation
Authors: Izumi Ryunosuke , Sato Takumi , Suzuki Safumi , Asada Masahiro
Published: August 2019

We proposed and fabricated resonant-tunneling-diode (RTD) terahertz oscillators integrated with a cylindrical cavity. Oscillation frequency of 3 THz is expected from theoretical analysis. As a preliminary experiment, the proposed oscillator was fabricated using electron-beam lithography with a three-layer-resist process. An oscillation of up to 1.79 THz was obtained in the fabricated oscillators, which was lower than the theoretical expectation. This was because of a parasitic capacitance of the metal post connecting the cavity and the RTD. Theoretical calculations, including this parasitic capacitance, agreed well with the experiment. The parasitic capacitance can be suppressed by adding a simple process to the cavity fabrication.
Quantitative perspectives in Cognitive Linguistics
Authors: Janda Laura A.
Published: August 2019

As a usage-based approach to the study language, cognitive linguistics is theoretically well poised to apply
quantitative methods to the analysis of corpus and experimental data. In this article, I review the historical circumstances that
led to the quantitative turn in cognitive linguistics and give an overview of statistical models used by cognitive linguists,
including chi-square test, Fisher test, Binomial test, t-test, ANOVA, correlation, regression, classification and regression
trees, naïve discriminative learning, cluster analysis, multi-dimensional scaling, and correspondence analysis. I stress the
essential role of introspection in the design and interpretation of linguistic studies, and assess the pros and cons of the
quantitative turn. I also make a case for open access science and appropriate archiving of linguistic data.
Contrastive semantics of human locomotion verbs
Authors: Kudrnáčová Naděžda
Published: August 2019

This paper is a contribution to a hitherto unexplored area in English-Czech contrastive semantics. It examines
differences in the construal of walking, the most prototypical type of human locomotion. Based on the data from
InterCorp, a synchronic parallel translation corpus, it presents a cognitive oriented analysis of the
semantics of English walk and its nearest Czech counterparts, i.e. jít and
kráčet. Despite their apparent commonalities, the verbs in question do not construe walking in the same way.
In contrast to jít, the construal of a motion situation in walk and kráčet
involves focus on leg movements and bodily position, amounting to a marked segmentation of the motion into individual quanta.
Focus on leg movements and verticality of the body is even more pronounced in kráčet, which can then serve an
evaluative function; such a possibility is not open for walk. Walk thus occupies an intermediate position between
the two verbs.
The near-synonymy of classifiers and construal operation
Authors: Dosedlová Aneta , Lu Wei-lun
Published: August 2019

This paper investigates the near-synonymy of classifiers, using Chinese kē and
zhū as illustration. We find that in [quantifier] – [classifier] – [noun], the two classifiers have
overlapping semantic prototypes due to their similar behavioral profiles. However, despite a shared functional core, the two
classifiers diverge in terms of which part of plant to profile. In particular, zhū highlights parts of
plant that are small and vulnerable, such as flowers and seedlings. In addition, small is another important
conceptual characteristic exclusively associated with zhū, which gives it a distinctive set of peripheral members
to include in that particular linguistic category, including mold, bacterium, and even biological and
chemical substance. Another important difference is the quantifier that precedes, where kē tends to
occur with lower numbers (typically under 10), while zhū with higher numbers (typically over 1,000). Accordingly,
we conclude that [quantifier] – [zhu] – [noun] tends to invoke a higher-resolution construal.
Construction in conversation
Authors: Hsieh Chen-Yu Chester , I-Wen Su Lily
Published: August 2019

Although the Construction Grammar (CxG) model has yielded fruitful findings, the role that pragmatics plays in language has not yet been fully considered in this theoretical framework. The recent development of spoken corpora, however, enables construction grammarians to develop a new approach called Interactional Construction Grammar, which incorporates interactional factors into CxG analysis to account for patterns that involve interpersonal functions and global contexts. Adopting this approach, the present study attempts to examine the use of a complement-taking mental predicatexiangshuoin Taiwan Mandarin conversation and analyze the co-occurrence patterns of this cognitive verb with different subjects. We identify three sequential patterns in whichxiangshuomost frequently occurs, including account-giving, contrast-projecting and involvement-constructing, and argue that only by taking into account the sequential context and interactional function can the distribution patterns of subjects and particles that recurrently collocate withxiangshuobe explained.
APO X, Y

Published: August 2019

The paper accounts for the Greek discourse topicalization construction APO X, Y and the sarcastic and humorous effects that arise in the context of Twitter exchanges. Our analysis is based on the analytical tools of the Lexical Constructional Model (henceforth LCM) as formulated inRuiz de Mendoza and Mairal (2008),Ruiz de Mendoza (2013), andRuiz de Mendoza and Galera (2014). For this purpose we have created a corpus of over 1300 real use tweets. The LCM enables us to treat the patricular uses of the APO X, Y construction. It is shown to be very useful in capturing emergent uses of an already established construction.

The role of the discount rate for emission pathways and negative emissions

Published: August 2019

The importance of the discount rate in cost-benefit analysis of long term problems, such as climate change, has been widely acknowledged. However, the choice of the discount rate is hardly discussed when translating policy targets—such as 1.5 °C and 2 °C–into emission reduction strategies with the possibility of overshoot. Integrated assessment models (IAMs) have quantified the sensitivity of low carbon pathways to a series of factors, including economic and population growth, national and international climate policies, and the availability of low carbon technologies, including negative emissions. In this paper we show how and to what extent emission pathways are also influenced by the discount rate. Using both an analytical and a numerical IAM, we demonstrate how discounting affects key mitigation indicators, such as the time when net global emissions reach zero, the amount of carbon budget overshoot, and the carbon price profile. To ensure inter-generational equity and be coherent with cost-benefit analysis normative choices, we suggest that IAMs should use lower discount rates than the ones currently adopted. For a 1000 GtCO2 carbon budget, reducing the discount rate from 5% to 2% would more than double today’s carbon price (from 21 to 55 $/tCO2) and more than halve the carbon budget overshoot (from 46% to 16%), corresponding to a reduction of about 300 GtCO2 of net negative emissions over the century.
Varition Analysis Of Collector Shift Time Period On Solar Water Heater Efficiency
Authors: Mustafa  , Sudarno  , Wahyudi
Published: August 2019

The working principle of a solar collector is to move solar radiation to the working fluid. Solar radiation that falls on the partial glass cover is partially reflected, some will be absorbed and some will be passed to the absorbent plate. The radiation that reaches the absorbent plate will be absorbed by the absorbent plate. The heat absorbed by the absorbent plate will be used to heat the fluid that works in the form of a flowing fluid. The purpose of this study was to design and make a wave plate solar collector with solar tracker, with an interval time of collector shift every 20 minutes, 40 minutes, 60 minutes. From the test results obtained the average efficiency in testing with the collector shift time interval of 20 minutes is 23.07%, with an interval of 40 minutes is 22.07%, and with an interval of 60 minutes is 21.31%.
Potential of Biomass Utilization in Rotary Kiln of Nickel Processing Plant
Authors: Pamungkas B C , Hadi H
Published: August 2019

Global energy-related CO2 emissions rose by 1.4% in 2017 and reached a historic high of 32.5 Gigatonnes (Gt). One of the biggest contributors to CO2 emission is coal combustion that emits 96.1 kg CO2 for each GJ energy production. Top consumers of coal in the world are the iron-steel industry (28.5%) and the non-metallic minerals (21.4%). Rotary kiln is one of the most energy consuming equipment in nickel pyro-metallurgy processing plant. The specific energy consumption for calcine production is determined to be 2.26 GJ/ton calcine. In the rotary kiln, coal is used as fuel and a reducing agent. Charcoal from palm kernel shell has similar characteristics with coal and very suitable to substitute coal. Charcoal from PKS has many advantages compared to other biomass: high fixed carbon content, high heating value, and low ash content. Charcoal from palm kernel shell can be used as fuel and a reducing agent. Potential 9.9% reduction of CO2 emission can be achieved by using 20% PKS charcoal as fuel and 5% PKS charcoal as a reducing agent with minimum impact on the current operation.

In this paper, we present an IoT-based monitoring system for recording the vibration of the induction motor. A 27mm piezoelectric is used to collect the vibration data from the motor. Each self-powered IoT node is supplied by the motor vibration its self by utilizing two 27mm piezoelectrics in series. We conducted an experiment with 3 scenarios, which aims to collect the vibration data from different positions, they are bottom, top and at the coupling. For each scenario, the speed of the induction motor is changed from low, middle to high speed. Based on our results, the proposed system is a success to monitor the motor vibration clearly. The results can display on the smartphone. Each node can send the recorded vibration to the cloud with an average delay of about 1 s.

E-learning is an internet-based learning program. It has been adopted in Institut Teknologi Sepuluh Nopember (ITS) since 2006, and called SAHRE-ITS. It is managed by Directorate of Academic Affairs in ITS. Despite quite long adoption in ITS, there are still a number of problems to confront. One of them is lack of intent of the lecturers as the main and vital users to adopt e-learning continuously. The research was to identify factors affecting the continuance intention of lecturers to adopt SHARE-ITS using some model: expectation – confirmation model (ECM), technology acceptance model (TAM), theory of planned behaviour (TPB), and FLOW theory. The variables used comprised 10 variables, i.e.: perceived usefulness, perceived ease of use, attitude, perceived enjoyment, concentration, subjective norm, perceived behavioural control, confirmation, satisfaction, and continuance intention. The results of the research indicate some factors affecting the continuance intention of the lecturers to use SHARE-ITS and suggest some recommendations for strengthening those factors. This research showed the factors of lecture’s satisfaction and perceived usefulness to SHAREITS positively and significantly affected the continuance intention to use SHARE-ITS. The factor of perceived ease of use among the lecturers positively and significantly affected the perceived usefulness among the lecturer towards SHARE-ITS. Those three factors were essential to consider as they affected the continued intention the lecturers to use SHARE-ITS. In addition, it is identified that the factor of perceived enjoyment in using SHARE-ITS by the lecturers positively and significantly affected their attitude in using SHARE-ITS. Accordingly, the researchers addressed recommendation within the contexts of service rendered by the administrator of SHARE-ITS, data integration, SHARE-ITS menu and navigation designs.

Solar radiation is very infulental on the photovoltaic performance in generating energy. The need for solar radiation estimation has become important in the design of photovoltaic system. Previous research has been done using Extreme Learning Machine (ELM) and Adaptive Neuro Fuzzy (ANFIS) methods. In this research, Genetic Algorithm Modified Fuzzy (GAMF) method used to estimate the solar radiation. Meteorogical dates used in this research are temperature, humidity, wind velocity and wind direction. There are 2 types of datas that are BMKG data and measurement data. Three experimental variations of input variation were performed for each data. For BMKG data the best estimation result is obtained when using humidity, temperature and wind velocity as variation inputs with RMSE and MAE of 145.19 and 72. While for the best result estimation result data obtained when applying humidity, temperature, wind speed and wind direction as variation inputs with values of RMSE and MAE were 1.44 and 0.65.

Image segmentation is one of the most important step in computer vision and image processing, which later will be used in image retrieval, object identifying and data classification. Image segmentation can be seen as classification problem, namely by marking each pixels according to certain characteristics. Support Vector Machine (SVM) is a classification method included in supervised learning. Supervised learning is a method which requires training and testing. Training sample used in training process isn’t always exist in few cases, especially in the image segmentation case. This particular research implemented SVM-based method which is Saliency-SVM for automatic data training selection in image segmentation. This method generates data training using SVM-based visual saliency detection where there is pre-segmentation step and trimap formation based on saliency information from visual saliency detection, HSV color space quantitation, histogram analysis and local homogeneity threshold. Data training produced is pixel belonging to positive (object) and negative (background). The step before segmentation done with SVM is feature extraction to create input vector in SVM. Object segmentation on the image is done by SVM based on SVM Trained Model. Test result from Saliency-SVM for this image segmentation has average accuracy value up to 94,84 % compared to the image ground truth

TiO2 photocatalyst is one of the Advanced Oxidation Processes (AOPs) methods which is very potential to be applied to treat wastewater. Modification of TiO2 with the addition of ZSM-5 as supporting material can increase the adsorption capacity and conductivity of water molecules. Those properties enable TiO2/ZSM5 composites to conduct photodegradation process within dye waste. TiO2/ZSM5 composites were prepared by sol gel method. The synthesized materials were characterized by X-ray diffraction (XRD), Energy Dispersive X-ray Scanning Electron Microscopy (SEM-EDX), and Brunauer-Emmett-Teller (BET). The effect of 2-Propanol to TiO2/ZSM-5 Composite Morphology was studied. The results from X-Ray Diffraction analysis revealed that the peak indicating the presence of anatase TiO2 on sample 2.5;5; and 10% TiO2/ZSM-5 composite. The increasing effect of Titanium precursors to TiO2/ZSM-5 composite carried out agglomerates on external surface of ZSM-5 as seen in SEM which was supported by surface area data from BET.

This research aimed to enhance properties of fly ash based geopolymer through usage of three types of rice husk ash (RHA). The replacement in the content of 0%, 3%, 5% and 10% by weight was chosen. The RHA used in this study were obtained from (i) the rice drying-process (ii), (iii) in house by burning RH at 600°C and 700 °C. Liquid sodium silicate (LSS) and sodium hydroxide (SH) solution were used as activating agents. The weight ratio of LSS to SH was 1.0 and total liquid to solid was 0.6. The geopolymer prepared without RHA (the control) gave an average compressive strength of 35.91±3.30 MPa. All types of RHA replacement at 3% resulted in an improvement of compressive strength. Further increasing RHA content resulted in an adverse effect on workability and compressive strength of the final products. The highest compressive strength value of 42.52±4.86 MPa was obtained at 3% replacement using RHA burnt at 700 °C. The density results showed a decreased when incorporation of high content of RHA was beyond 5%.

A non-covalent nanohybrid of Ferrocene (Fc) with grapheme (Gr) via π-π interaction was proposed for amaranth detection. The synthesized Fc-Gr composite was modified on glassy carbon electrode (GCE) and characterized by cyclic voltammetry (CV) as well as differential pulse voltammetry (DPV). Cyclic voltammogram and differential pulse voltammogram demonstrated successful fabrication of Fc-Gr composite-modified GCE for amaranth detection. DPV was used to obtain a linear range of amaranth detection. The linear range of amaranth detection with a modified sensor was expressed from 10 to 250 μM of amaranth. The limit of detection was obtained at 155 nM of amaranth. Based on these results, the developed sensor provides a good alternative for the determination of amaranth. Moreover, the developed sensor can hopefully be utilized and adapted for detection of other substances.

Here, we successfully prepare graphene/poly (diallyldimethylammonium chloride) – poly (styrene sulfonate) (G/PDADMAC-PSS) polyelectrolyte composites by simple mixing method. The effect of NaCl adding at 2, 4, 6, 8 and 10 % wt. on the sizing of polyelectrolyte composites (PECs) is investigated. The concentration of NaCl ion plays an important role in size control by the formation of the primary polyelectrolyte composites and following by the agglomeration itself. The electrochemical properties are evaluated by cyclic voltammetry demonstrating that G/PDADMAC-PSS PECs at 8 %wt. can yield the highest specific capacitance of 68 m F.cm−2; at 10 mV sec−1
