Sistem monitoring dalam penanganan kerusakan peralatan elektronik di STMIK STIKOM Indonesia saat inidilaksanakan dengan melakukan pencatatan di buku besar.Kendala yang dihadapi adalah sering terjadinya kesimpang siuran informasi peralatan yang sudah diperbaiki dan yang belum diperbaiki.Teknisi yang telah memperbaiki kadang tidak melaporkan ke Bagian Rumah Tangga hasil dari perbaikan tersebut.Hal ini menyebabkan Bagian Rumah Tangga, BAA, dan PK II tidak tahu informaasi mengenai kondisi peralatan saat itu sehingga pelayanan STMIK STIKOM Indonesia terhadap dosen dan mahasiswa menjadi kurang efektif.Penelitian ini akan diawali dengan melakukan observasi terhadap sistem yang sudah ada kemudian dilanjutkan dengan requirement analysis dari pengguna sistem dan berikutnya dilakukan proses pengembangan sistem. Tahap akhir dari penelitian ini adalah melakukan pengujian dengan menggunakan metode black box testing. Sistem monitoring penanganan kerusakan peralatan elektronik ini dibangun dengan tujuan dapat memantau penanganan kerusakan peralatan yang dilakukan oleh teknisi.Proses monitoring akan diawali dengan penginputan data kerusakan oleh bagian rumah tangga yang kemudian dapat langsung dilihat oleh bagian teknisi dan PK II. Jika perbaikan telah selesai dilakukan maka bagian teknisi akan menginputkan status dan tanggal selesainya perbaikan tersebut. Dengan adanya sistem ini diharapkan dapat meningkatkan kualitas pelayananpada STMIK STIKOM Indonesia.

Tujuan dari penulisan artikel ini adalah menganalisa sistem jaringan saraf tiruan menggunakan model perceptron pada pengenalan pola pulau di Indonesia. Model jaringan perceptron biasa digunakan untuk pengenalan pola, karakter, maupun simbol, termasuk pola pulau-pulau di Indonesia. Analisis dilakukan berdasarkan nilai alpha (α) dan threshold (θ) pada setiap pola masukan pada perhitungan manual dengan excel dan diimplementasikan menggunakan program visual basic. Selanjutnya analisis dilakukan dengan cara membandingkan nilai alpha (α) dan threshold (θ) pada excel maupun visualbasic dan hasil pengenalan pola pulau-pulau besar di Indonesia didapatkan hasil yang sama, sehingga dapat disimpulkan keakurasian antara perhitungan keduanya. Analisis juga dilakukan terhadap laju pemahaman yang dimodifikasi mempengaruhi kecepatan iterasi, hal ini dilihat dari perubahan nilai net pada setiap perubahan nilai alpha (α).Hasil analisis perubahan laju pemahaman pada tabel modifikasi laju pemahaman menunjukkan bahwa semakin besar laju pemahaman semakin besar pula respon unit keluaran sehingga proses pemahaman menjadi lambat, begitu pula sebaliknya.

Peningkatan volume sampah berbanding lurus dengan peningkatan konsumsi dan jumlah penduduk Malang yang rata rata sebesar 0.73 persen per tahun. Data menunjukkan bahwa terjadi peningkatan volume sampah pada tahun 2015 sebesar 150% di TPAS Talangagung. Zona 1 TPAS Talangagung sebagai zona penimbunan sampah dikelola dengan metode sanitary landfill dengan kapasitas 59.500 M3. Pemodelan dan simulasi dilakukan dengan menggunakan pendekatan sistem dinamik. Hasil simulasi menunjukkan bahwa hasil akumulasi sampah tahun 2015 dan 2016 melebihi kapasitas zona sebesar 7 persen yang dapat ditimbun dalam zona penimbunan lain. Hasil prediksi dalam pengembangan model yang telah divalidasi menunjukkan bahwa hasil akumulasi sampah pada tahun 2021 dan 2022 telah melebihi kapasitas zona hingga 201.9%. Hal ini mengisyaratkan bahwa pengelolaan sampah pada tahun tersebut memerlukan dua zona penimbunan yang masing-masing seluas 0.7 ha. Penimbunan sampah harus didiamkan selama kurang lebih 4 hingga 7 bulan untuk proses degradasi sampah organik menjadi kompos. Sampah dalam zona penimbunan yang telah menjadi kompos dapat diambil digunakan untuk pertanian dan zona dapat diisi dengan sampah organik yang baru.

Nowadays, obesity has been becoming one of the most popular problems to the global health. Molecular design with the aid of computing method is an efficient and cost-saving solution in the initial research of new potential drugs for the treatment of obesity. This study focused on benzyl amino chalcone derivatives as they have a benzyl group that can mimic the hydrophobic effect of the long chain carbon of Orlistat, a drug used to treat obesity. Initially, 102 molecular structures were prepared and docked into the protein by using AutoDock Vina version 1.5.6. Fourteen structures having good docking scores were selected to synthesize using a Claisen-Schmidt reaction. Afterward, these synthesized chalcones were tested biological activity against pancreatic lipase by spectrophotometric determination at a wavelength of 405 nm, using p-nitro phenyl palmitate as the substrate. The co-crystallized ligand of pancreatic lipase enzyme was redocked into the enzyme and the RMSD was 1.4976 A which showed the ligand and the protein preparation could regenerate the practical experiment. As the docking results, the binding affinities of top ten compounds varied from -8.6 and -10.2 kcal/mol. Biological testing resulted in 4 derivatives with IC50 >120 μM, 8 derivatives with 60 μM < IC50 < 120 μM and 2 derivatives with IC50 < 60 jliM. In addition, the docking results also confirmed the key role of amino acid Seri 52 in interacting with the ligands. The benzyl amino chalcone derivatives are required for further investigation to become a lead compound for anti-obesity drug discovery.

Desarrolla la prueba indiciaria relacionada al razonamiento presuntivo. El estudio tuvo como fuente de análisis el razonamiento que realizan magistrados cuando aplican la prueba indiciaria en la resolución de casos. Para ello se recurrió a la jurisprudencia más saltante, de donde se extrajo los datos empíricos necesarios e ilustrativos que conllevaron a determinar la triple manifestación o posibilidad de realización: inducción, deducción y abducción. Según la jurisprudencia y la doctrina se usa o sustenta indistintamente el razonamiento presuntivo en la inducción, la deducción y la abducción y, por consiguiente, es visible la falta de coherencia y racionalidad plena principalmente en las decisiones judiciales.

An Exponent of Scottish Common Sense Philosophy in Revolutionary South America: José Joaquín de Mora
Authors: Macintyre Iona
Published: November 2018

Revolutionary movements in nineteenth-century South America saw the region's historic grounding in scholasticism confronted by the ideas of the eighteenth-century French Enlightenment. This article examines a subsequent development: Spanish liberal man of letters José Joaquín de Mora's attempt to implant Scottish common sense philosophy as the dominant school in the republics that were emerging from Spanish rule and gradually forming nationally as Argentina, Bolivia, Chile and Peru. Furthering our knowledge of Scottish intellectual influence abroad, Mora's enterprise also illuminates two contentious issues of the period in Spanish America, namely how to cultivate young minds in a revolutionary context, and the place of European culture, in this case Scottish, in the immediate post-colonial period.

Agroforestry, as an improved cropping system, offers some advantages in terms of yield, biodiversity, erosion protection or habitats for beneficial insects. It can fulfill the actual sustainability requirements for bioenergy production like food supply, nature conservation, stop of deforestation. However, competition between intercropped species for water, nutrients and light availability has to be carefully considered. A field trial with shading nets was conducted in Southwest Germany to evaluate the influence of different shading levels (−12, −26, and −50% of full sunlight) on biomass growth, dry matter yield and biogas quality parameters of maize (Zea mays L., cv. ‘Corioli CS’). Shading the plants causes a delayed development, a reduction in height and leaf area index and a slower senescence. Dry matter yields were reduced about 18%, 19%, and 44% compared to 21.05 Mg ha−1 year−1 at full sunlight. Biogas and methane yields were also significantly reduced, the 50% shading treatment showed a reduction of 45% for both parameters. Further, shading led to higher crude protein and crude ash contents. If silage maize is grown under shade, the yields of dry matter, biogas, and methane are nearly halved under 50% shade. Cultivation up to 26% shading could be possible.
Development and Use of Simple Sequence Repeats (SSRs) Markers for Sugarcane Breeding and Genetic Studies

Published: November 2018

Recently-developed molecular markers are becoming powerful tools, with applications in crop genetics and improvement. Microsatellites, or simple sequence repeats (SSRs), are widely used in genetic fingerprinting, kinship analysis, and population genetics, because of the advantages of high variability from co-dominant and multi-allelic polymorphisms, and accurate and rapid detection. However, more recent evidence suggests they may play an important role in genome evolution and provide hotspots of recombination. This review describes the development of SSR markers through different techniques, and the detection of SSR markers and applications for sugarcane genetic research and breeding, such as cultivar identification, genetic diversity, genome mapping, quantitative trait loci (QTL) analysis, paternity analysis, cross-species transferability, segregation analysis, phylogenetic relationships, and identification of wild cross hybrids. We also discuss the advantages and disadvantages of SSR markers and highlight some future perspectives.

Published: November 2018

In spring, transition from a total mixed ration (TMR) to pasture requires rumen adaptions for the cow. It had been shown that transition period does not necessarily mean an increased risk for subacute ruminal acidosis (SARA). After adaption to pasture, however, supplying low amounts of concentrate did indicate increased risk, but caused no adverse effects on rumen morphology and absorption capacity. The present study aimed to investigate the effect of transition, and how a supply of 4.5 kg dry matter concentrate·cow−1 · day−1 during fulltime grazing influenced different rumen parameters. During a 12-week trial eleven rumen-cannulated dairy cows were observed during transition from confinement to pasture (PG; n = 6) and compared to cows fed TMR indoors (CG; n = 5). The CG stayed on a TMR based ration (35% corn silage, 35% grass silage, 30% concentrate; dry matter basis), whereas the PG slowly switched to a pasture-based ration (week 0 and 1 = TMR, week 2 = TMR and 3 h pasture·day−1, week 3 and 4 = TMR and 12 h pasture·day−1, and week 5 to 11 = pasture combined with 4.5 kg DM concentrate · cow−1·day−1). Papillae surface area decreased during transition and increased again during fulltime grazing, while the fractional absorption rate of volatile fatty acids (VFA) was not influenced. This suggests only a limited effect of papillae surface area on VFA absorption rate. Feeding changes resulted in different fermentation profiles of VFA. Changing ratio of starch to sugar during transition to fulltime grazing plus concentrate supply did not lead to lower rumen pH. In conclusion, the concentrate supply combined with high fermentable grass during fulltime grazing increased papillae surface area but did not affect absorption rate or rumen pH, so that risk for SARA was not increased.

This study presents mathematical models for predicting VO2max based on a 20 m shuttle run and anthropometric parameters. The research was conducted with data provided by 308 young healthy people (aged 20.6 ± 1.6). The research group includes 154 females (aged 20.3 ± 1.2) and 154 males (aged 20.8 ± 1.8). Twenty-four variables were used to build the models, including one dependent variable and 23 independent variables. The predictive methods of analysis include: the classical model of ordinary least squares (OLS) regression, regularized methods such as ridge regression and Lasso regression, artificial neural networks such as the multilayer perceptron (MLP) and radial basis function (RBF) network. All models were calculated in R software (version 3.5.0, R Foundation for Statistical Computing, Vienna, Austria). The study also involved variable selection methods (Lasso and stepwise regressions) to identify optimum predictors for the analysed study group. In order to compare and choose the best model, leave-one-out cross-validation (LOOCV) was used. The paper presents three types of models: for females, males and the whole group. An analysis has revealed that the models for females ( RMSE C V = 4.07 mL·kg−1·min−1) are characterised by a smaller degree of error as compared to male models ( RMSE C V = 5.30 mL·kg−1·min−1). The model accounting for sex generated an error level of RMSE C V = 4.78 mL·kg−1·min−1.
A Novel Ultrasonic Cavitation Peening Approach Assisted by Water Jet
Authors: Bai Fushi , Wang Liang , Saalbach Kai-Alexander , Twiefel Jens
Published: November 2018

Ultrasonic cavitation peening is an environmentally friendly technology to improve surface properties. In the traditional ultrasonic cavitation peening process, specimens have to be immersed in a liquid and temperature control is required, which limits the wide usage of this technology due to the geometry and complicated setup. In order to improve this process, water is slowly jetted (75 mL/min) into the gap between the sonotrode tip and specimen surface. The water jet makes the gap full of water. Thus, cavitation bubbles can be generated in the gap as the traditional ultrasonic cavitation peening process. In this case, the water container and temperature control are no longer necessary. The goal of this contribution is to evaluate the treatment effectiveness of this novel approach by the impact loads, the volume loss, the surface roughness, the microhardness and the microstructure of the specimen surface. The results indicate that a higher input power is beneficial and there would be an optimal gap width for this novel ultrasonic cavitation peening process.
Impact of a Pilot-Scale Plasma-Assisted Washing Process on the Culturable Microbial Community Dynamics Related to Fresh-Cut Endive Lettuce
Authors: Fröhling Antje , Ehlbeck Jörg , Schlüter Oliver
Published: November 2018

Cold plasma is described as a promising technique for the treatment of fresh food. In particular, the application of plasma-treated water gained interest in fresh-cut produce processing. This study aimed to evaluate the effectiveness of plasma-treated water (PTW) to decontaminate lettuce during washing on a pilot-scale level with special interest in the dynamics of the culturable microbial community in a first approach. PTW was used in pilot-scale washing at different processing steps, and the total viable count (TVC) of endive lettuce was determined after treatment and after storage (seven days, 2 °C). Microflora representatives were identified using MALDI-ToF MS. The highest reduction of TVC (1.8 log units) was achieved using PTW for washing whole lettuce before cutting. The microbial community structure showed high variations in the composition along the processing chain and during storage with a decrease in diversity after washing with PTW. PTW reduced the microbial load of endive lettuce; however, this was not clearly detectable at the end of storage, similar to other sanitizers used in comparable studies. To assure the safety of fresh products, detailed knowledge about the microbial load and the composition of the microbial community close to the end of shelf life is of high interest for optimized process design.
Postbuckling and Free Vibration of Multilayer Imperfect Nanobeams under a Pre-Stress Load
Authors: Emam S. A. , Eltaher M. A. , Khater M. E. , Abdalla W. S.
Published: November 2018

This paper investigates the postbuckling and free vibration response of geometrically imperfect multilayer nanobeams. The beam is assumed to be subjected to a pre-stress compressive load due to the manufacturing and its ends are kept at a fixed distance in space. The small-size effect is modeled according to the nonlocal elasticity differential model of Eringen within the nonlinear Bernoulli-Euler beam theory. The constitutive equations relating the stress resultants to the cross-section stiffness constants for a nonlocal multilayer beam are developed. The governing nonlinear equation of motion is derived and then manipulated to be given in terms of only the lateral displacement. The static problem is solved for the buckling load and the postbuckling deflection in terms of three parameters: Imperfection amplitude, size, and lamination. A closed-form solution for the buckling load in terms of all of the beam parameters is developed. With the presence of imperfection and size effects, it has been shown that the buckling load can be either less or greater than the Euler buckling load. Moreover, the free vibration in the pre and postbuckling domains are investigated for the first five modes. Numerical results show that the effects of imperfection, the nonlocal parameter, and layup on buckling loads and natural frequencies of the nanobeams are significant.

Recently, fire accidents in buildings have become bigger around the world, and it has become necessary to build an efficient building disaster management system suitable for fires in a Smart City. As building fires increase the number of casualties and property damage, it is necessary to take appropriate action accordingly. There has been an increasing effort to develop such disaster management systems worldwide by applying information communication technology (ICT), and many studies have been conducted in practice. In this paper, an augmented reality (AR)-based Smart Building and Town Disaster Management System is suggested in order to acquire visibility and to grasp occupants in case of fire disasters in buildings. This system provides visualization information and optimal guide for quick initial response by utilizing smart element AR-based disaster management service through linkage of physical virtual domain in the building. Additionally, we show a scenario flow chart of the fire extinguishment process according to the time from the ignition stage to the extinguishment stage in the building.

The requirement for effective image search, which motivates the use of Content-Based Image Retrieval (CBIR) and the search of similar multimedia contents on the basis of user query, remains an open research problem for computer vision applications. The application domains for Bag of Visual Words (BoVW) based image representations are object recognition, image classification and content-based image analysis. Interest point detectors are quantized in the feature space and the final histogram or image signature do not retain any detail about co-occurrences of features in the 2D image space. This spatial information is crucial, as it adversely affects the performance of an image classification-based model. The most notable contribution in this context is Spatial Pyramid Matching (SPM), which captures the absolute spatial distribution of visual words. However, SPM is sensitive to image transformations such as rotation, flipping and translation. When images are not well-aligned, SPM may lose its discriminative power. This paper introduces a novel approach to encoding the relative spatial information for histogram-based representation of the BoVW model. This is established by computing the global geometric relationship between pairs of identical visual words with respect to the centroid of an image. The proposed research is evaluated by using five different datasets. Comprehensive experiments demonstrate the robustness of the proposed image representation as compared to the state-of-the-art methods in terms of precision and recall values.

Monitoring and diagnosis of rotating machines has become an effective and indispensable tool for the efficient and timely detection of defects, avoiding then incidents that can have serious economic and human consequences. Bearings are the most sensitive parts of these machines; this is why special attention must be paid to its monitoring. This paper presents a methodology for diagnosing an aircraft air compressor bearing using neural networks that have been optimized by genetic algorithms. We used in our study a database of vibratory signals that were recorded on a test bench from bearings with different defects. The faults features are extracted from these noisy signals using the estimate of the spectral density. The diagnostic capacity of obtained model has been demonstrated by a comparative study with two other automatic classifiers, which are discriminant analysis and neural networks whose training has been done with the Back-Propagation algorithm. This approach has the advantage of simultaneously ensuring the optimal structure of the neural network and accomplishing its learning. The importance of this study is the construction of a diagnostic tool that is characterized by efficiency, speed of decision making and ease of implementation not only on the computers on the ground, but also on the mounted calculators on aircraft.

In wireless body area networks, temperature-aware routing plays an important role in preventing damage of surrounding body tissues caused by the temperature rise of the nodes. However, existing temperature-aware routing protocols tend to choose the next hop according to the temperature metric without considering transmission delay and data loss caused by human posture. To address this problem, multiple research efforts exploit different metrics such as temperature, hop count and link quality. Because their approaches are fundamentally based on simple computation through weighted factor for each metric, it is rarely feasible to obtain reasonable weight value through experiments. To solve this problem, we propose an enhanced mobility and temperature-aware routing protocol based on the multi-criteria decision making method. The proposed protocol adopts the analytical hierarchy process and simple additive weighting method to assign suitable weight factors and choose the next hop while considering multiple routing criteria. Simulation results are presented to demonstrate that the proposed protocol can efficiently improve transmission delay and data loss better than existing protocols by preventing the temperature rise on the node.
Mobile Robot Path Planning with a Non-Dominated Sorting Genetic Algorithm
Authors: Xue Yang
Published: November 2018

In many areas, such as mobile robots, video games and driverless vehicles, path planning has always attracted researchers’ attention. In the field of mobile robotics, the path planning problem is to plan one or more viable paths to the target location from the starting position within a given obstacle space. Evolutionary algorithms can effectively solve this problem. The non-dominated sorting genetic algorithm (NSGA-II) is currently recognized as one of the evolutionary algorithms with robust optimization capabilities and has solved various optimization problems. In this paper, NSGA-II is adopted to solve multi-objective path planning problems. Three objectives are introduced. Besides the usual selection, crossover and mutation operators, some practical operators are applied. Moreover, the parameters involved in the algorithm are studied. Additionally, another evolutionary algorithm and quality metrics are employed for examination. Comparison results demonstrate that non-dominated solutions obtained by the algorithm have good characteristics. Subsequently, the path corresponding to the knee point of non-dominated solutions is shown. The path is shorter, safer and smoother. This path can be adopted in the later decision-making process. Finally, the above research shows that the revised algorithm can effectively solve the multi-objective path planning problem in static environments.

The effect of aerosols is an important indicator of climate change. Sulfate aerosols, as the major scattering aerosols, which have attracted more and more attention in recent years. The Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) were utilized to investigate the spatial distribution of sulfate aerosols and their radiative forcing characteristics over East Asia in 2010. Results showed that sulfate aerosols were mainly distributed over eastern China (24–43° N, 101–126° E), especially in the Sichuan Basin. The concentration of sulfate aerosols decreased with increasing altitude over East Asia. It also exhibited obvious seasonal variations, where the largest range of sulfate aerosol concentrations was found in summer, with a maximum of 2.4 μg kg−1 over eastern China. Although sulfate aerosol concentrations varied slightly during day and night, there was still a significantly difference in the sulfate aerosol radiative forcing. Specifically, the magnitude of the direct radiative forcing induced by sulfate aerosols at the surface was approximately −3.02 W m−2 in the daytime, while that was +0.24 W m−2 in the nighttime. This asymmetric change that was caused by the radiative forcing of sulfate aerosols between day and night would have significant impacts on climate change at the regional scale.
Application of GPU-Based Large Eddy Simulation in Urban Dispersion Studies
Authors: Kristóf Gergely , Papp Bálint
Published: November 2018

While large eddy simulation has several advantages in microscale air pollutant dispersion modelling, the parametric investigation of geometries is not yet feasible because of its relatively high computational cost. By assuming an analogy between heat and mass transport processes, we utilize a Graphics Processing Unit based software—originally developed for mechanical engineering applications—to model urban dispersion. The software allows for the modification of the geometry as well as the visualization of the transient flow and concentration fields during the simulation, thus supporting the analysis and comparison of different design concepts. By placing passive turbulence generators near the inlet, a numerical wind tunnel was created, capable of producing the characteristic velocity and turbulence intensity profiles of the urban boundary layer. The model results show a satisfactory agreement with wind tunnel experiments examining single street canyons. The effect of low boundary walls placed in the middle of the road and adjacent to the walkways was investigated in a wide parameter range, along with the impact made by the roof slope angle. The presented approach can be beneficially used in the early phase of simulation driven urban design, by screening the concepts to be experimentally tested or simulated with high accuracy models.

Eutrophication events are frequent in Inner Danish waters and critical loads are exceeded for much of the Danish sensitive terrestrial ecosystems. The Danish air quality monitoring program combines measurements and model calculations to benefit from the complementarities in data from these two sources. Measurements describe actual status, seasonal variation, and temporal trends. Model calculations extrapolate the results to the entire country and determine depositions to specific ecosystems. Measurements in 2016 show annual depositions between 7.5 and 11 kg N/ha to terrestrial ecosystems, and a load to marine waters of 5.3 kg N/ha. The deposition on Danish marine waters in 2016 was calculated to be 73,000 tons N with an average deposition of 6.9 kg N/ha. For terrestrial areas, the deposition was calculated to be 57,000 tons N with an average deposition of 13 kg N/ha. This is above critical loads for sensitive ecosystems. Long-term trends show a 35% decrease since 1990 in measured annual nitrogen deposition. At two out of four stations in nature areas, measured ammonia levels exceeded critical levels for lichens and mosses. Conclusions: Nitrogen loads and levels to Danish nature is decreasing, but critical loads and levels are still exceeded for sensitive ecosystems. Combining measurements and model calculations is a strong tool in monitoring.
