Abstract
Planning the structure of operation taking into account the dynamical contemporary market is one of the most serious challenges for industry in the XXI century. It is particularly complex and complicated especially for the multi-process scheduling that is characteristic for modern large industrial plants. The method allowing solving the mentioned problem should be based on the analysis of constraints as any manageable system is limited in achieving its goals by a number of constraints. The most important of these is resource availability. Taking into account the critical resources chain it is possible to create complex schedules in multi-process environments. In the paper is presented analysis of results, obtained for such conditions, using original application adding the process of scheduling.

Published: July 2022

Abstract
Superfluous properties of Graphene and CNT reinforced composites are making significant revolution in the application area of metal matrix nano-composites. Fabrication of these composites without any flaw is the challenging task due to its inherent properties such as limited wettability, unique structure, load transfer efficiency, shape and size. The individual reinforcements such as 0.1wt.% B4C, 0.1wt.% Graphene and 0.1wt.% CNT were successfully incorporated in common Al7075/10wt.% SiC base through squeeze casting method combined with ultrasonic vibration. The influence of reinforcements on the mechanical, metallurgical and electrical properties of the composites was analysed in this study. The hardness value of the B4C-based, Graphene-based and CNT-based composites has enhanced to 167 BHN, 145 BHN and 135 BHN respectively from the base matrix. Tensile strength has also improved to 239 MPa, 324 MPa and 308 MPa. In the case of micro-structural characteristics, the addition of Graphene in the Graphene reinforced composite improved the grain structure due to the grain refining effect followed by the CNT and B4C reinforced composites with the similar weight fraction and processing methods. The influence of various reinforcements was analysed using Optical Microscope (OM), Scanning Electron Microscope (SEM) and Energy-Dispersive X-ray analysis (EDX) techniques. Addition of Graphene and CNT increased the electrical conductivity of respective composites to 24.2 MS/m and 21.1 MS/m.

Abstract
Modern manufacturing systems consist of a sequence of robotic systems, such as robotic cells, which are widely used in the industry. As they become commonplace and play important roles in modern industrial production, efficient modelling and use of robotic cells become a necessity. Robotization brings many measurable benefits. It enables effective utilization of both human resources and the possessed machine park and thus contributing to the improvement of product quality and efficiency. Industrial robots not only increase the growth of productivity, by replacing man in monotonous works, requiring enormous, not achievable for human precision but above all ensure the accuracy and repeatability of the product quality. Appropriate design and modelling of robotic manufacturing systems are crucial in the efficient integration of work cell components and proper maintenance of robotic production systems. Therefore, new solutions for programming environments in industrial applications are sought which not only allow reprogramming of industrial robots but also enable the virtual design of new production lines, which in turn allows the faster introduction of higher quality products. This article presents the modelling and programming of robotic work cells in the Siemens Process Simulate environment.

Published: July 2022

Abstract
In this paper, by mapping datasets to a set of non-linear coherent states, the process of encoding inputs in quantum states as a non-linear feature map is re-interpreted. As a result of the fact that the radial basis function is recovered when data is mapped to a complex Hilbert state represented by coherent states, non-linear coherent states can be considered as a natural generalisation of the associated kernels. In this paper, as an example of kernels based on non-linear coherent states, we propose kernel functions based on generalized hypergeometric functions, as orthogonal polynomial functions. The suggested kernel is implemented with the support vector machine (SVM) on two well known datasets (make_circles, and make_moons) and outperforms the baselines, even when the level of noise is high. In addition, we study the impact of the geometrical properties of the feature space, obtained by the non-linear coherent states, on the SVM classification task, by considering the Fubini–Study metric of the associated coherent states.

Published: July 2022

Abstract
Engine emissions have become one of the major problems of the world today. Therefore, researchers need to find ways to reduce engine emissions. There are many available methods to reduce emissions or improve engine performance such as using an alternative engine or using alternative fuels. The simplest method is by introducing additives to the currently used fuel and engines. Nanoparticles of zinc oxide, titanium oxide, aluminium oxide, and cerium oxide are among the popular additives used by researchers. The results from the research have been very positive, as it successfully reduced engine emissions. However, there are concerns about the toxicity of the emissions that exposed hazards to human health. A few researchers introduced carbon-based nanomaterials as an additive to improve engine performance and reduce engine emissions. The use of carbon-based nanomaterials is very promising since it poses little to no effect on human health. Graphene is a carbon-based nanomaterial used as an additive in this study. This study aimed to forecast the effects of graphene nanoplatelets’ addition to engine performance. The study used torque, power, brake-specific fuel consumption, and brake thermal efficiency as performance parameters. The prediction models consider speed, load, and blend concentration in the calculation. A full-quadratic model with help of Minitab software is used to develop the prediction model. The model is then presented in surface plot and contour plot. The results show that the prediction model agrees with the experimental data with ±10% accuracy. In conclusion, the RSM model of graphene nanoplatelets’ effects on diesel engine performance is producible using full quadratic calculation.

Published: July 2022

Abstract
Sugarcane bagasse, a by-product of sugar industry is a potential lignocellulose biomass for bio-oil production by hydrothermal liquefaction (HTL). The catalyst and the reaction parameters are important for the higher bio-oil yield. Hence, by the sol-gel method, cobalt oxide catalyst was synthesized, characterized by FTIR, X-ray diffraction, nitrogen adsorption and studied for the HTL of sugarcane bagasse with varying reaction time, catalyst/biomass weight ratio and water/biomass weight ratio. Formation of face-centered cubic spinel of Co3O4 was confirmed from the XRD peaks at 2Θ positions of 18, 31, 37, 45, and 65° and FTIR absorption bands at 558 and 654 cm−1 attributed to stretching vibrations of Co-O, having the Co3+ in octahedral and tetrahedral coordination respectively. A high BET surface area of 413.63 cm2/g obtained may be attributed to the citric acid added during sol-gel synthesis, which got decomposed off during the calcination. The highest yield of bio-oil was found to be 57.6% at the reaction time of 120 min, catalyst/biomass ratio of 0.4, water/biomass ratio of 28, 250°C and initial CO pressure of 45 bars, compared to 35.2% for non-catalytic HTL, confirmed its catalytic activity.

Authors: Rao K Shubha , Vasudha Karanam 
Published: July 2022

Abstract
Battery technology has been widely used in various applications such as electric vehicles, smart grids, renewable energy systems, and sustainable power applications in recent years. The type, rating, and operating characteristics of batteries vary from one application to another. For example, Electric Vehicles (EVs) need lightweight batteries capable of producing fast energy and withstanding frequent charge/discharge cycles. Renewable energy applications require batteries that can store large energy in the time of excessive electric power generation and can substitute renewable energy sources to supply power in times of non-generation. As batteries are an electro-chemical phenomenon and are generally expensive, it is essential to establish an effective battery model to analyze its behavior under different operating conditions. In this regard, this paper presents a comprehensive study of various battery modeling approaches widely used for the characterization of batteries employed as energy sources for electric vehicles. A simple modified generic battery model is developed and simulated for the ANR26650M1 Li-ion battery in a MATLAB-Simulink environment. The modified generic model includes a polarization voltage term to represent the open-circuit voltage accurately and the polarization resistance term is slightly modified. The model parameters are deduced from the data sheet provided by the battery manufacturers. The discharge curve obtained through simulation is validated with the one given in the datasheet.

Published: July 2022

AbstractThe research on Zinc oxide nanoparticles has become very important on these days due to its unique property and wide range of applications in all the branches of science. In this study, we synthesized ZnO nanoparticles through a simple and cost-effective wet chemical precipitation approach. The XRD spectra revealed the hexagonal wurtzite structure in the prepared ZnO nanoparticles. The UV-Vis absorption peak of the as - prepared ZnO sample was identified at 301.2 nm and was observed to be blue shifted in comparison to the bulk counterpart. The transmittance analysis of the prepared ZnO sample showed very high transmittance to the visible range of light. The widening of the optical band gap was observed in the preparation ZnO sample. The band gap of the synthesized ZnO sample was found to be 3.7943 eV. The theoretical estimation of particle size in the prepared ZnO sample was performed using the Brus model and the particle size was estimated to be 4.38 nm. This study revealed the potential application of prepared ZnO nanoparticles as transparent electrode in solar cell.
Relationship of Age, Gender, and Body Proportion to Outdoor Thermal Comfort in Open Space, Case Study: Green Park, Kitakyushu, Japan
Authors: Hartabela D , Dewancker B , Vidyana C 
Published: July 2022

Abstract
Outdoor thermal comfort is influenced by many factors, including environmental factors and human factors. A person’s age and gender are thought to influence the survey answers. The older a person is, the lower the standard of comfort will be, and vice versa. Meanwhile, men are easier to gain thermal comfort than women. In addition, the proportion of a person’s body weight and height calculated by Body Mass Index (BMI) is also thought to affect the level of thermal comfort. The greater the distance from the proportional body, the higher the standard of comfort. These hypotheses will be scientifically proven through this research. This research was conducted for one year by quantitative methods using a printed questionnaire media. The total number of respondents was 415 people, with details of 97 people in the summer (2020), 86 people in the fall (2020), 117 people in the winter (2021), and 115 people in the spring (2021). The sampling method used a simple random sampling approach, and the questionnaire was directly distributed in Green Park, one of the urban parks in Kitakyushu, Japan. The relationship between the three variables would be analysed by the multivariate analysis method. Based on the analysis results, there is no significant correlation of age, gender, and body proportion to outdoor thermal comfort.

Authors: Putri S H , Haerdy R S M , Nurdini A 
Published: July 2022

Abstract
In 2015 the local government relocated some residents from several squatter settlements on government land into Rusunawa Rancacili. Consequently, the relocation has affected occupant lifestyle changes as a form of adaptation in the vertical housing. This adaptation process usually has undesirable impacts. One example is the occupation of public circulation and corridors as personal storage by the occupants. This condition can reduce the space for the disaster evacuation process due to obstruction of public access. Therefore, a simulation is conducted to describe the evacuation possibilities using the actual occupation condition of the flats. The simulation compares the evacuation time required by the occupants in the ideal condition with the actual condition. This study focuses on identifying various factors that hinder the disaster process in the circulation area where obstacles exist. The simulation was conducted using the Agent-Based Modeling (ABM) method to describe occupant behavior during the evacuation process. Data were obtained through field observation surveys and interviews with Rusunawa Rancacili Block 2 residents. It is identified that the longer evacuation time is caused by the closure of exit access, the corridor obstacle with personal belongings, and the walking speed of the elderly group of occupants. The results of this study could provide a recommendation based on the design and operation management of public housing.

Abstract
Public libraries have a function as a place of activity for its visitors. Activities performed at this facility require excellent comfort, including spatial comfort, visual comfort, thermal comfort, and most importantly audial comfort. Currently, micro libraries are starting to appear as public libraries in urban parks, among other things, to increase public interest in reading and provide educational space for underprivileged communities. The various activities that occur around and in the urban park produce noise which of course disturbs the micro library in it. This research focuses on the Bima Microlibrary located in Taman Bima, as a prototype micro library designed by SHAU Architecture and Urbanism. This research uses a descriptive quantitative method by measuring the noise level that occurs in the object of study. Through this research, it is known that the noise level that occurs in the object of study reaches a very high and uncomfortable level. Therefore, this research also recommends engineering that can be done for the study object to attain audial comfort. It is hoped that the results of this study can encourage designers to pay more attention to audial comfort for educational facilities, especially those built in public areas, such as micro libraries.

Abstract
Limited land available in big capital cities makes building development change from horizontal into vertical one. High demand for living space along with high-density population causes carbon emissions from electricity used for lighting and cooling increasing as well. This research is trying to invent vertical housing design concept that responsive into environment, especially Bengkulu City, as the solution and alternative for living space that low in energy used. Organic analogy was used as a method to conduct natural principles of Australian Pinecone into apartment design. Pinecone physical appearance and the structure of Pinecone transversal section were interpreted as an apartment plan configuration and exterior design of the building. First, the transversal section of Pinecone structure that consists of seed, wing, and axis, were interpret as an apartment plan configuration, which is the balcony area, apartment unit, and corridor. Next, the spike shape of Pinecone scale inspires angular shape on the outer side area of apartment floor plan and the façade as well. There are three alternatives from design process iteration that later being analyzed using Sefaira simulation to find energy use in the building. Result showed that apartment building design that use a lot of Pinecones principle analogy has lower energy consumption, which is 63 KWh/year/m2. This number is still under the average energy use intensity for apartment building in Indonesia. Nevertheless, there are still some limitations and minus point on the final design that can be further research in the future.
