Over the last three years, there has been a tremendous increase in the amount of road accidents in Mataram City-Lombok with majority of the victims being motorcycle riders between the ages of 16-40 years. The age difference may have an impact on the rider’s behavior which in turn leads to road accidents. This study aims at investigating the influence of age groups on motorcycle riders resulting to traffic violations and road accidents in Mataram City. Data was collected using questionnaire survey for which 600 respondents participated covering 6 sub-districts in Mataram City. A Structural Equation Modeling (SEM) using AMOS V.22.0 was constructed to analyze the motorcycle rider behavior. The developed model was made up of behavioral, violation and accident latent variables, with four variables of behavior, three variables of violation, and two observed variables of accident. Three age groups were used in this study with three categories consists of 15-24 years, 25-44 years, and 45-64 years old. This study found that these riders behaviors varied significantly with regards to traffic violations. The age groups of riders between 15-24 years and 45-64 years has a 65% influence on traffic violation compared to those between the ages of 25-44 years. Traffic violations with regards to road accidents was however, found to be less significant for all age group. Traffic violations committed by riders between ages of 45-64 years were found to be 14% less than those between the ages of 15-44 years. The analysis obtained from the data indicates that there are differences among the three listed age groups.

Authors: Agus Nugroho Soewignjo , Yusa Muhamad , Ongko Andarsin
Published: March 2019

As a part of natural geography systems, rock slopes have treasured amount of natural resources potential. The rock materials could be utilized to fulfill several needs, especially to construct buildings. However, society sometimes have taken advantages from the slope’s existence in wrong ways. The exploitations toward rock materials, either through manual or modern way (blasting) have caused some cracks occurred. These cracks have reduced the stability of rock slopes and easily triggered failures on rock slopes. In this paper, the stability of a rock slope will be precisely discussed by using Geological Strength Index (GSI) and was analyzed by using finite element method. The rock samples were taken from Pangkalan (West Sumatera, Indonesia), which this location is also vulnerable to rock slope failures. Geological Strength Index was obtained by doing manual observations on rock sample’s properties, i.e. joint, cracks, and discontinuity. The result was consisted of rock’s properties. Meanwhile, the analysis by using finite element method produced an outcome in form of safety factor. This result could be made as a reference for pre-disaster mitigation in Pangkalan.
Re-weathering of stabilized clay shale with Portland cement behavior
Authors: Idrus M Alatas , Pintor T Simatupang , Wawan Kuswaya , Panji
Published: March 2019

Clay shale is a claystone which in fresh condition has a very high shear strength. When it reacts with the atmosphere or hydrosphere it will weather so that the shear strength of clay shale will drop drastically. The weathering potential of clay shale is generally done by the slake durability test and the weathering process is measured by disintegration ratio test (DR). The strength of clay shale that has fully weathered will increase again when it is stabilized with a minimum of 6% PC (Portland Cement). It was found from the wetting drying cycle process testing that durability of re-weathering of stabilized clay shale with PC is increased compared to natural clay shale. Disintegration ratio of natural clay shale DR was smaller than stabilized clay shale with 6% PC. Additionally, more than 6% PC increased the durability of re-weathering of clay shale.
The effect of lime Ca(OH)2 to the constant of granulation rate (k) of Sidoarjo mud (LuSi) and its grain size distribution
Authors: Pasmar Dasyri , Endah Mochtar Noor , Altway Ali
Published: March 2019

Sidoarjo mud (LuSi) is very hot and sticky mud-like substance produced by eruption of Kujung, Kalibeng, and Pucangan formations caused by well exploration for gas in Porong, Sidoarjo, East Java, Indonesia. LuSi submerged villages, industrial areas, and rice fields in Porong. The eruption is still taking place so that it needs more area and higher dike surrounded to retain the mud. Therefore, it is very urgent to use LuSi in huge volumes such as for borrowed materials. LuSi grain size and its strength, however, do not meet the borrowed materials requirement. Therefore, the grain size was improved using granulator drum and lime Ca(OH)2 was used to increase its strength. The grain size produced by granulator was affected by length, diameter, and rotation rate of granulator drum, and also by constant of granulation rate ‘k’ that was function of other parameters, inclination angle of granulator drum (S), moisture content (W), and water temperature (T). The results show that lime needed for stabilization is 10% of LuSi dry weight. The “k” is affected by lime where parameters (S) and (W) become smaller and (T) is higher. Lime also produces dryer granular, higher water resistance, and shorter granulation process. Besides, higher water temperature during granulation process is needed to develop bigger grain size for granular stabilized-LuSi.

Published: March 2019

The article presents the results of the analysis of the characteristics of heat exchangers methods for determining their mathematical models. The necessity of the availability of the mathematical model during the synthesis of automatic control systems with desired properties. The method of identification of the thermal control object by the testing control action is proposed. Since technological control objects always be an energy of interaction the energy efficiency criterion applied for automatic formation of the control action. Also the analytical self-adjusting system with a reference model in the form of an integrating link was applied. From the analytical researches it follows that the movement of the system along the optimal trajectory occurs at a constant speed and does not depend on the properties of the control object, and the optimal control depends on the properties of the control object, time, and technological requirements. It is shown that mathematical models of heat exchangers of the first and second orders are determined quite simply. The accuracy of the mathematical model parameters is limited only by the accuracy of the experimental data. The quality of control systems with desired properties, synthesized by experimental, and accurate models are virtually indistinguishable.
Overview of ground-based generator towers as cloud seeding facilities to optimize water resources in the Larona Basin
Authors: Prasetio Anom , Widjiantoro Bambang L. , MT Nasution Aulia
Published: March 2019

The Larona River Basin which cover an area of 2477 km2, including the three cascading lakes: Matano, Mahalona, and Towuti Lakes, is a strategic watershed which acts as the water resource for three hydropower plants that supply 420 Megawatt of electricity to power a nickel processing plant and its supporting facilities and electricity need of the surrounding communities. The maximum and minimum operating levels of Towuti Lake are 319.6 meters (asl) and 317.45 meters (asl) respectively. Total live storage between these two elevations is 1,231,500 m3. Currently, the operation average outflow from Towuti Lake to the power plants is 130.1 m3/second which is resulting in a total annual outflow volume of 4,103,000 m3. By comparing the outflow volume with the live storage volume, it is obvious that present live storage has a limited capability to carry over the capacity from wet to dry years. During a dry year, the outflow drops to 100 m3/second. Thus, the optimization of water resources management in the Larona Basin is important to fulfil the need to produce the energy sources. To deal with the decrease of the Lakes water level, the Weather Modification Technology in the form of cloud seeding is needed to produce rain that will increase the water volume in the Lakes. The dispersion of cloud seeding material into the targeted clouds can be done by surface seeding using the Ground-Based Generator (GBG) which utilize towers to release cloud seeding materials. The tower locations should be in certain altitude or higher locations and amounts in order to operate effectively with optimum results. The water discharges generated from the process is expected in accordance with the planning. The weather modification process is inefficient when the discharge is overflow the spillway channel. Cost incurred is in approximate of US$ $11,133,258.36 if the company is utilizing Diesel Power Plant and Steam Power Plant instead of the weather modification technology.
Application of enhanced gravity technique for separation of iron phase from LD slag
Authors: Makhija Dilip , Rath Rajenda Kumar , Mukherjee Asim Kumar
Published: March 2019

The basic oxygen process of steel making produces steel slag at a rate of about 120 kg/t. The steel slag also known as LD slag contains metallic iron and other mineral phases. The metallic iron is recovered through magnetic separation while the non-metallic is rejected because of its poor physical and chemical properties. Qualitative mineralogical analysis and XRD studies indicated that major mineral phases are dicalcium silicate and calcium ferrite. While both these phases are useful for recycling in iron making process the presence of phosphorus is a deterrent for its use in the iron making process. The electron probe micro analysis revealed that phosphorus is mostly associated with dicalcium silicate phase in the form of calcium phosphate. The phosphorus was present in negligible amounts in iron bearing phases i.e. calcium ferrite and wustite. The liberation size of phosphate mineral was in the range of 30–50 microns. The physical separation of phosphorus was attempted by grinding the LD slag to different sizes and then subjecting to centrifugal jigging. The centrifugal jigging was carried out at 0.5 mm, 0.25 mm and 0.1 mm size. The products of centrifugal jigging were characterised and it was observed that maximum recovery with acceptable grade of product was obtained at 0.5 mm grind size. The product obtained at this size analyzed 0.79% P and 34% Fe.

Published: March 2019

Current trends in economic development emphasize the importance of crisis management at both the macro and microeconomic levels. The analysis of current problems of Russian enterprises has shown that at present some outdated approaches to this problem prevail in domestic science and practice. Therefore, a new scientific direction “Anti-crisis business regulation” is becoming increasingly important.

In the world practice, the term crisis-management is not associated solely with the problems of bankruptcy. On the contrary, it is a broader concept that includes a range of problems. Therefore, the technology of anti-crisis business regulation should be universal enough and allow to solve any socio-economic, financial and organizational problem.

The basic tool of anti-crisis business regulation are methods of diagnostics, monitoring and forecasting of the crisis phenomena at the enterprises which have, first of all, preventive character. One of such approaches is a method of forecasting the probability of insolvency (bankruptcy) on the basis of logit-model. This approach, tested on the sample of enterprises of Penza region, has shown a significant increase in the accuracy of forecasts compared to traditional models, for example: Altman and others.

At present, practice-oriented training is taking on particular importance. Innovative projects carried out on the basis of the university with the participation of interdisciplinary project teams can be one of the elements of that kind of training. In order to provide the training of specialists that meet the requirements of international standards, it is necessary to develop mechanisms for attracting non-budgetary sources for investment in the field of education. The main direction of development of the education system in a market economy is the implementation of reforms aimed at overcoming the lack of financing of the higher education system. The participation of private investors will allow diversifying sources of financing in the implementation of practice-oriented project training. The possibility of implementing innovative projects with the participation of specialists from different levels of training and different professional competencies contributes to the creative approach development and problem-solving. In the course of work, participants can increase their professional level and expand the range of their competencies. The possibility of bringing a project to the commercialization stage will allow the project team (with the participation of the university) to create new jobs, integrate financial resources from the project implementation to the development of follow-up projects. Practice-oriented project training is the most important factor in social and economic development and the realization of the country's intellectual potential, determining the qualitative characteristics of labor forces and playing an important role in the development of the economy and society.

Authors: Dorofeeva Y.A. , Zubkova M.N.
Published: March 2019

A legal entity as a union recognized in law and absent as an independent entity outside the law, exists and carries out its activities through the governing bodies whose composition and competence are always predetermined by the norms of positive law. Undoubtedly, the rights of the governing bodies of a legal entity, as well as the duties of the head of the organization, must be strictly predetermined and have limits defined by law. Failure of this rule would mean the possibility of abuse of the right by the governing bodies of legal entities, their release from the obligation to lead the organization in good faith and reasonably, evasion from the fulfillment of obligations assumed by the legal entity through the sole executive body or another governing body of the organization. In order to prevent harm to the organization and third parties, the governing bodies of the legal entity, the legislator set certain rules for the activities of the governing bodies of the legal entity, as well as the grounds for applying measures of responsibility for violating such rules. The responsibility of the head includes the recovery of damages caused by his fault to a legal entity. The purpose of the study is to analyze the grounds and conditions for recovery of damages caused by the head of the organization in the legislation of the Russian Federation and arbitration practice. The objectives of the study are to determine the grounds for liability of the head of a legal entity in the form of damages, show the genesis of the formation of Russian legislation and the practice of its use by courts on recovering losses of a legal entity from the head of an organization, identify criteria for determining the presence of both good faith and reasonableness in the behavior of managers of legal entities, brought to responsibility in the form of the obligation to pay damages to the organization they lead. In carrying out the study, such methods were used as: general scientific - analysis, synthesis, comparison, generalization, historical method; private-scientific: formal-legal, comparative-legal, allowing to consider the issues of bringing to responsibility in the form of recovery of damages of the head of a legal entity; Formal legal method for determining the content of abstract categories - reasonableness, good faith, permissible behavior, method of system-structural analysis - to study the possibility of applying damages as a form of responsibility for the guilty behavior of a special entity - the head of a legal entity The result of the study is the establishment of the grounds and conditions for applying to the head (former head) of a legal entity responsibility in the form of recovery of damages caused to the organization managed by it, in the legislation of the Russian Federation and judicial practice. The findings and results of the study can be used for further research and as educational material, in legislative work and in law enforcement practice.

Gastric cancer and paraneoplastic dermatomyositis as complications of an unrecognized juvenile polyposis syndrome
Authors: Schiemer Moritz , Schmitt-Graeff Annette , Brass Volker , Hasselblatt Peter
Published: March 2019

Juvenile polyposis syndrome is a rare autosomal-dominant disorder characterized by multiple hamartomatous polyps in the gastrointestinal tract. It is associated with an increased risk of gastrointestinal cancer. We report the case of a 49-year-old woman presenting with proximal muscle weakness, weight loss, severe anemia, and melena. One year before, the diagnosis of a “fundic gland polyposis” was presumed after endoscopic evaluation for iron deficiency anemia had shown numerous polyps limited to the gastric mucosa. On admission, the diagnosis of dermatomyositis was made based on laboratory results with a marked elevated creatine kinase as well as the presence of characteristic clinical findings and muscle histology. Upper endoscopy revealed multiple pedunculated, edematous polyps in the stomach without apparent cancerous lesions intraluminally. Infiltration of the muscular layer was not detectable on endoscopic ultrasound. Histopathological examination of the polyps showed smooth outer surfaces and multiple dilated cystic glands, consistent with hamartomatous juvenile-type polyps. Magnetic resonance imaging revealed a peritoneal mass close to the greater curvature of the stomach, which was identified as a poorly differentiated adenocarcinoma by laparoscopic sampling. Immunohistochemical analysis of resected polyps was remarkable for a loss of SMAD4 expression, a finding that is very commonly observed in patients with gastric juvenile polyposis syndrome. Despite initial treatment response to glucocorticoids and chemotherapy, the patient died 5 months later due to progressive illness. Patients with gastric juvenile polyposis and SMAD4 mutations are at a high risk of developing gastric cancer; hence, early gastrectomy should be considered.

2-C6F6)]2, Fv[Ir(CH2=CH2)2]2 (X-ray), Fv[Ir(PMe3)(H)2]2 (X-ray), and (2,2′,3,3′-tetra-tert-butylFv)[Ir(CO)2]2 were accomplished. When irradiated in C6H6, these molecules succeeded to varying degrees, and best for (2,2′,3,3′-tetra-tert-butylFv)[Ir(CO)2]2, in the double metalation of the aromatic ring to engender ligating Ir2(ortho-μ-C6H4)(CO)2 (Ir–Ir) moieties, in addition to their precursor mono(phenyliridium hydride) constructs. A competing photochemical pathway is evident by the formation of diastereomers of Fv (or 2,2’,3,3’-tetra-tert-butylFv) [Ir(CO)(Ph)(H)]2 and the resulting dehydrogenated ligated [Ir(CO)(Ph)]2 (Ir–Ir). The structures of FvIr2(ortho-µ-C6H4)(CO)2 (Ir–Ir) and trans-Fv[Ir(CO)(Ph)]2 (Ir–Ir) were corroborated by X-ray analyses. Efforts to realize C–H bond activations with C6H12 generally failed or fared very poorly, with the exception of the tert-butylFv system, which enabled single, but not further, insertion to give (2,2′,3,3′-tetra-tert-butylFv)[Ir(CO)(Cy)(H)][Ir(CO)2] in 34% yield. To explore the relevant chemistry of phenyl- and alkyliridium species attached to Fv, several such derivatives were made by independent routes, adding knowledge to the fundamental behavior of this category of molecules. Where appropriate and for comparative purposes, similar reactions were performed on the corresponding Cp- and 1,2-di-tert-butylCpIr(CO)2 relatives.

Objective The objective of this article was to compare the performances of health care-associated infection (HAI) detection between deep learning and conventional machine learning (ML) methods in French medical reports.

Methods The corpus consisted in different types of medical reports (discharge summaries, surgery reports, consultation reports, etc.). A total of 1,531 medical text documents were extracted and deidentified in three French university hospitals. Each of them was labeled as presence (1) or absence (0) of HAI. We started by normalizing the records using a list of preprocessing techniques. We calculated an overall performance metric, the F1 Score, to compare a deep learning method (convolutional neural network [CNN]) with the most popular conventional ML models (Bernoulli and multi-naïve Bayes, k-nearest neighbors, logistic regression, random forests, extra-trees, gradient boosting, support vector machines). We applied the hyperparameter Bayesian optimization for each model based on its HAI identification performances. We included the set of text representation as an additional hyperparameter for each model, using four different text representations (bag of words, term frequency–inverse document frequency, word2vec, and Glove).

Results CNN outperforms all other conventional ML algorithms for HAI classification. The best F1 Score of 97.7% ± 3.6% and best area under the curve score of 99.8% ± 0.41% were achieved when CNN was directly applied to the processed clinical notes without a pretrained word2vec embedding. Through receiver operating characteristic curve analysis, we could achieve a good balance between false notifications (with a specificity equal to 0.937) and system detection capability (with a sensitivity equal to 0.962) using the Youden's index reference.

Conclusions The main drawback of CNNs is their opacity. To address this issue, we investigated CNN inner layers' activation values to visualize the most meaningful phrases in a document. This method could be used to build a phrase-based medical assistant algorithm to help the infection control practitioner to select relevant medical records. Our study demonstrated that deep learning approach outperforms other classification learning algorithms for automatically identifying HAIs in medical reports.

Computational Intelligence Re-meets Medical Image Processing

A Comparison of Some Nature-Inspired Optimization Metaheuristics Applied in Biomedical Image Registration

Background Diffuse lung diseases (DLDs) are a diverse group of pulmonary disorders, characterized by inflammation of lung tissue, which may lead to permanent loss of the ability to breathe and death. Distinguishing among these diseases is challenging to physicians due their wide variety and unknown causes. Computer-aided diagnosis (CAD) is a useful approach to improve diagnostic accuracy, by combining information provided by experts with Machine Learning (ML) methods.

Objectives Exploring the potential of dimensionality reduction combined with ML methods for diagnosis of DLDs; improving the classification accuracy over state-of-the-art methods.

Methods A data set composed of 3252 regions of interest (ROIs) was used, from which 28 features were extracted per ROI. We used Principal Component Analysis, Linear Discriminant Analysis, and Stepwise Selection – Forward, Backward, and Forward-Backward to reduce feature dimensionality. The feature subsets obtained were used as input to the following ML methods: Support Vector Machine, Gaussian Mixture Model, k-Nearest Neighbor, and Deep Feedforward Neural Network. We also applied a Deep Convolutional Neural Network directly to the ROIs.

Results We achieved the maximum reduction from 28 to 5 dimensions using LDA. The best classification results were obtained by DFNN, with 99.60% of overall accuracy.

Conclusions This work contributes to the analysis and selection of features that can efficiently characterize the DLDs studied.
Pressure-induced local symmetry breaking upon liquid–liquid transition of GeI4 and SnI4
Authors: Fuchizaki Kazuhiro , Sakagami Takahiro , Iwayama Hiroshi
Published: March 2019

SnI4 and GeI4 have been confirmed to have another liquid state appearing on compression. To identify the microscopic pathway from the low- to high-pressure liquid states, the structure of these liquids in the appropriate thermodynamic regions was analyzed using a reverse Monte Carlo method. The occurrence of pressure-induced symmetry lowering of molecules, from regular tetrahedral to ammonia-like pyramidal symmetry, was then recognizable in these systems. This symmetry lowering is reflected in the change in shape of the molecular form factor. The latter change occurs abruptly near the expected transition pressure in liquid SnI4, whereas it proceeds gradually in GeI4. This is consistent with our observation that SnI4 seems to undergo a first-order liquid–liquid transition, whereas the transition seems to end up with a crossover in liquid GeI4. Interestingly, when the molecular density becomes high, it is possible for the two-body intermolecular interaction to have a double-minimum character, which offers two characteristic length scales corresponding to two liquid states with different densities. However, quantum chemical calculations show that molecular deformation for this type of symmetry lowering results in an increase in electronic energy, which leaves the problem of the physical origin for this anisotropic deformation. We speculate that this symmetry lowering occurs as a precursor to the whole change in the liquid structure.
Non-acoustical parameters and sound absorption characteristics of porous polyurethane foams
Authors: Ning Jingfeng , Zhao Guiping , He Xiping
Published: March 2019

The present paper investigates the relationships between non-acoustical parameters and sound absorption characteristics of the porous polyurethane foams based on the proposed simplistic unit cell model. The simplistic unit cell model, in which the inner shape of each unit cell is spherical and the nodes at the joint have a triangle concave cross section shape, is established from foaming process and scanning electron microscope (SEM) pictures of the porous polyurethane foams. The non-acoustical parameters and sound absorption characteristics of the porous polyurethane foams are expressed as functions of the geometric parameters of the simplistic unit cell model. The present predictions are in good agreement with the existing experiments and numerical results. Finally, the correlating relationships between the viscous and thermal effects and sound absorption coefficients of the porous polyurethane foams are discussed using the simplistic unit cell model. It is demonstrated that the simplistic unit cell model could describe the microstructure characterization and sound absorption properties of the porous polyurethane foams and the influence of the viscous effect on the sound absorption coefficients is more obvious than that of the thermal effect in the studied frequency ranges.
