Research of scanning speed and orientation of the model to the resulting surface roughness in the process of Selective Laser Melting

Abstract

The article focused on the influence of part orientation on the surface roughness of cuboid parts during the process of fabricating by SLM technology. The components, in this case, is simple cuboid part with the dimensions 15 mm x 15mm x 30 mm. SLM or Selective Laser Melting is Additive manufacturing technology based on the Powder Bed Fusion process. SLM is designed to use high power-density laser to melt and fuse metallic powder. A part is built by selectively melting and fusing regions of metallic powders within and between layers. For the research purposes, five different orientations in the X-axis of the cuboid part were set: 0°, 30°, 45°, 60°, and 90°. The internal structure was set at a value of 100%. In this research, we manufactured five specimens for scanning speed 650 mm.min-1 and five specimens for scanning speed 1000 mm.min-1. In the research metallic powders were used, namely austenitic stainless steel SS 316L. In this experiment, we manufactured a total of 10 specimens. Surface parameters (Ra, Rz, Rq) were measured five-time in a row for each print. Prints were carried out on an SLM machine from Renishaw with the designation AM400. After the 3D printing, the surface “A” was investigated by portable surface roughness tester Mitutoyo SJ-210. Surface roughness in the article is shown in the form of graphs. Results show an increase in part roughness with an increasing degree of part orientation. When the direction of applied layers on the measured surface was horizontal, a significant improvement in surface roughness was observed. Findings in this paper can be taken into consideration when designing parts, as they can contribute to achieving lower surface roughness values.

Utilization of Waste Heat Recovery to Reduce Water Content in Low-Calorie Coal with Fluidized Bed Dryer

Abstract

Coal drying process using FBD (fluidized bed dryer) which utilizes low temperature waste heat, especially from industrial air heaters, has been developed in the United States by the GRE (Great River Energy) team since 1997. Technology is still considered an expensive investment. This study uses a prototype FBD with a drying heat source is an air heater that simulates the amount of water content that can be removed in low-calorie coal for boiler use. Furthermore, it can be considered the use of waste heat recovery from machines in the industry as a substitute for the energy source of the dryer by the air heater. The water content or Total Moisture Content that can be removed by using FBD with an air heater dryer energy source is 20%. The savings due to TM which has decreased by 20% in the industrial scale of the power plant can be calculated as 650,289 EUR/Year. The savings will be even greater, if the energy of the air heater dryer is replaced with waste heat recovery from industrial machines such as air heaters or boilers

Performance Evaluation of 5G in Sub-6GHz

Abstract

As a successor to the present 4G technology, 5G is a modern technology with a new interface that is being developed. The main purpose of 5G is to deliver a diversified collection of services to clients worldwide, including fast data speeds, wider coverage, low latency, cheap cost, high system capacity, and a variety of connectivity alternatives. Every major carrier intends to build both millimetre wave and sub-6 5G networks, but they choose to start with the lowest frequency bands and work their way up the frequency spectrum. The sub-6 spectrums are a better option for 5G. The recent deployments of the 5G networks are focused on the sub-6GHz spectrums. However, there are limited works reported on the 5G in sub-6GHz and this has motivated us to evaluate the performance of the 5G network in sub-6GHz spectrums. This project evaluates the performance of a 5G sub-6GHz network and the performance of the 5G is compared with the 4G Long-Term Evolution (LTE) network. The Vienna 5G System Level Simulator is a numerical model of wireless communication networks that is used to develop and improve mobile communication standards. It allows the community to do repeatable simulations of crucial scenarios in preparation for 5G and beyond. The performance of the 5G sub-6GHz throughputs is evaluated using the Vienna 5G Simulator. Extensive simulation works that considered a variety of factors, i.e., bandwidths, the number of users, users speed, and carrier frequencies were carried out to evaluate the performance of the 5G sub-6GHz network. The numerical findings indicate that 5G sub-6GHz performance is always better than LTE performance under identical simulation circumstances, demonstrating that 5G always outperforms LTE. The average cell throughput of the 5G sub-6GHz is 8 times more than the 4G network. The average peak throughput dropped when the mobility speed of the users increased. The throughput of the 5G network is directly proportional to the frequency bandwidth allocated.

Smart IoT Mobile Medication Dispenser

Abstract

The increase in the population of senior citizens created a new challenge of the shortage of healthcare workers to take care of the elderly. The elderly with multiple chronic conditions face problems in managing their daily medication intake. This has inspired us to design a low-cost Smart Internet of Things (IoT) Mobile Medication Dispenser (SMMD) to take care of the daily medication intake of the elderly. SMMD consists of hardware (medication dispenser) and software (an app for the user to control the SMMD and program the time to dispense the medication). The NodeMCU is used to control the stepper motor, organic light-emitting diode (OLED), and motor driver. The OLED displays the current time and the time set by the caregiver/elderly to take the medicine. The SMMD with three wheels enables it to move and dispense medication to the elderly. The NodeMCU is connected to the Firebase database to access the time required to dispense the medicine. The total cost of SMMD is USD50 and is affordable for the elderly from the lower-income group and making the process of taking medicine not a hassle for the elderly. The price of SMMD can be much lower when it is mass-produced

IOT based Smart Environmental Monitoring for Oyster Mushroom Production

Abstract

This paper presents an Internet of Things (IoT) smart environmental monitoring for oyster mushroom production which is based on Arduino microcontroller. These IoT sensors measures various changes like the humidity and temperature and sent to the Arduino microcontroller for configuring the control algorithm. Oyster mushrooms (Pleurotus ostreatus) can be produced from a wide array of agricultural waste material, which makes them the easiest mushrooms grown. It can grow at moderate temperature ranging from 20 to 300 C and humidity 55-70% for a period of 6 to 8 months in a year. The misting system can automatically control the water pumping system on the misting site based on the moisture content of the soil media acquired from the moisture content sensor. Misting is the best and widely used to get good propagation, a balance in humidity and transpiration is needed to allow water and nutrient uptake without excess dehydration especially in mushroom culture. If the growing medium is also saturated with water, there is a potential for the growth of bacteria.

The effect of chilled casting ductile iron to the shringkage porosity on the surface of the Y-Shaped specimen

Abstract

One of the surface hardening processes is chill casting. Chill casting is used for surface hardening of nodular cast iron materials. The problem that often occurs in the chill casting method is porosity which is influenced by the fast cooling rate between the casting object and the mold wall. This study aims to analyze the microstructure, hardness, and porosity that will form on the surface of the Y-shaped specimen after chilled casting. The material used for casting the Y-Shape specimen is nodular cast iron and the chill material is stainless steel plate. The chill is varied with a thickness of 0.2mm and 0.4mm and will be coated on the surface of the sand mold wall then the chill is preheated at a temperature of 700oC and 900oC, then pouring is done at a temperature of 1400oC. The average hardness value on the surface of the specimen is 500HV-900HV, but in the middle area the hardness only reaches 200HV while the microstructure results in the surface layer are cementite and ledeburite phases, but in the middle area ferrite, and perlite are seen surrounding the nodule graphite structure. In the chill-coated area, although the hardness is high, there are micro-porosities and macro-porosities formed randomly.

Vehicle Speed Prediction Using YOLOv4 and XGBoost Regression

Abstract

There are so many ways to detect vehicles’ speed these days, which can be categorized into two different approaches: a non-computer-vision based and a computer-vision based. In this paper, we propose a computer-vision-based approach using YOLOv4 and XGBoost Regression. To predict vehicles’ speed efficiently, we use YOLOv4 for vehicle detection and XGBoost regression for speed prediction. In order to get the best speed prediction, we build our dataset by recording the local traffic and measuring their speed using a speed gun. From those traffic videos, we detect vehicles by using YOLOv4 to generate its bounding boxes. From the bounding boxes, we can extract its coordinates relative to the screen and its time to get from point A to point B. This information will be our input, and the speed from the speed gun will serve as the target to train our XGBoost regression model. In this paper, we conduct several experiments using various inputs and parameters to get the best model. Our experiments conclude that our speed prediction approach using YOLOv4 and XGBoost regression has a very high performance regarding to the ground truth with an MAE of just 2 km/h.

Regression Test List Sharding in a Distributed Test Environment Presenter

Abstract

One of the major issues during the regression test of the new version of Real Time Operating System (RTOS) is the time involved in test case execution. The main reason being a single embedded system device under test (DUT) is used to execute the test list containing several test cases. This traditional method of regression test also leads to wasted productivity of the other devices at hand that could be otherwise used during this regression test. Hence, in this paper, we propose a technique that aims at reducing the overall regression test cycle time of a newer version of a Real Time Operating System (RTOS) by employing a method known as “test-list sharding” in a distributed test environment. In the proposed work, multiple DUTs are connected to the test server via a communication network. The test server executes the test list containing several test cases and performs the test-list sharding, that is, distributing test cases to different DUTs and executing them in parallel. After the test is executed on the DUT, the test results are sent back to the test server which will summarize all the results. In the proposed work, the sharding is done by distributing the test cases without overloading or under loading any of the DUTs. Test list is sharded in such a way that the same tests are not sent to multiple DUTs. The main advantage of the proposed method is that the test sharding can be easily scalable to accommodate any number of devices that can be connected to the test server. Also, the test list sharding is done in a dynamic way so that the tests are distributed to an idle DUT that has completed a test execution and ready for another test to execute. The comparison study of executing a sample test list sequentially on a single DUT and distributed test system with multiple DUTs is performed. Results obtained showed the performance gain in terms of test cycle time reduction, scalability, equal load distribution and effective resource utilization.

Design of River Floating Trash Traps Using Recycled Plastic Bottles and Waste Analysis and Characterization of Collected Waste in Odiongan, Romblon, Philippines

Abstract

Water pollution is a significant problem in the Philippines, and rivers are one of the bodies of water that are affected by this pollution. Accumulation of solid waste from rivers that hinder the quality and life below water is one reason for this pollution. According to the Comprehensive Land Use Plan of the Municipality of Odiongan, rivers and creeks are used as solid and liquid dumping sites, resulting in pollution. This project aims to design floating trash traps installed in the municipality's three (3) rivers. These plastic-made traps are strategically placed near downstream rivers to stop solid waste from floating further downstream without hampering aquatic life movements and are installed in a parabolic path to maximize their collection capacity. The materials used in the proposed design consist of plastic bottles, poultry net, and nylon. Fieldwork was done at the rivers and characterized the collected wastes by their wet weight. The floating trash traps generated a total of 260.56 kilograms. A total of 74% (193.08 kilograms) of biodegradable waste were collected, consisting of leaves, twigs, logs, driftwoods, and branches of trees. For non-biodegradable, 5% (13.3 kilograms) of trash were gathered containing plastic packaging, styrofoam, miscellaneous plastics, and cigarette butts. 15% (39.05 kilograms) of the waste is recycled material (plastic bottles and cans), and 6% (15.13 kilograms) is residual waste, mainly heavily soiled plastics, were accumulated. In conclusion, the design of the floating trash traps has been proven as a potential solution for collecting marine wastes, particularly in rivers.

CLOUD BASED AGILE TEST AUTOMATION USING OPEN SOURCE TOOLS

Abstract

Cloud Automation Testing is a concept that entails testing cloud-deployed applications that make use of cloud-based resources. Companies can save provisioning time by employing a cloud infrastructure system for testing because the cloud allows test servers to be provisioned as needed. Selenium is a free and open-source testing tool that may be used to test a variety of online applications. However, selenium has a number of drawbacks, including the inability to generate structured reports and cross-browser testing. To work around these issues, selenium is frequently combined with additional tools like as JMeter, Junit, and Test-NG. By combining and comparing several tools that are expected to be effective for cloud automation testing alongside selenium, this article presents a study of some of the technologies that are estimated to be effective for cloud automation testing by combining and comparing various technologies together with selenium

DESIGN OPTIMIZATION OF COMPOSITE RESIN PELTON TURBINE BUCKET USING SOLIDWORKS

Abstract

The Pelton turbine is a type of water turbine whose working principle utilizes the potential energy of water which is converted into kinetic energy through a nozzle. The fluid coming out of the nozzle push the bucket and rotates the Pelton turbine which ultimately produces electrical energy. Micro-hydro power plants that usually use Pelton turbines need to be developed to remote villages to meet electricity needs in Indonesia. Pelton turbine buckets, which are usually made of metal, are not only difficult to manufacture so they have to be specially ordered, but also easy to rust. Therefore, in this study, the bucket was made easier and simpler using an epoxy resin composite material reinforced with palm fiber. This makes it lighter and more corrosion resistant. The results of this study indicate that the epoxy composite fiber reinforced with 9% fiber volume has a higher tensile strength than the volume fraction 0%, 3%, 5%, 7%. The maximum tensile strength for 9% fiber content is 32.61 N/mm2. Then the tensile strength results are applied to the Pelton turbine bucket geometry with laboratory scale sizes that have been varied into 3 different size models in: bowl width (b), bowl height (h), and bowl height (h1). All variations of the laboratory scale bucket design that were simulated using solidworks software with 33.055 N loading had a safety factor above 6. The bucket design that has the highest safety factor is design 3 where the minimum deformation is 0.07922 mm, stress is 2.6670575 N/mm2, strain is 0.000557, and the safety factor is 6.945.

FISGA-IAE ASVSF Algorithm for Effectively Solving the Localization Problem of a Mobile Robot

Abstract

The use of Smooth Variable Structure Filter (SVSF) has been successfully overcoming the Localization problem. Generally, its performance depends on the knowledge of noise statistics for the process and measurement. Because this knowledge is not available, both are determined and kept to be constant for all iterations. However, this approach will lead SVSF to the divergence condition. Accordingly, a novel improvement, namely FISGAIAE ASVSF, is proposed in this paper. This name represents the role of the Genetic Algorithm (GA) used to optimize the Fuzzy Inference System (FIS) that is initially applied for enhancing the adaptive SVSF. Unlike the traditional way, this strategy can recursively update the noise covariance of the process 𝑄 and measurement 𝑅. In detail, FIS supervises the adaptive SVSF to reduce the mismatch between the reference and estimated covariance of error innovation. To effectively arrange the membership function of FIS, the GA is adopted. Lastly, it is implemented to solve the localization problem of mobile robots in the synthetic simulation perception. By using the term RMSE, the comparatively presented results are analyzed. And the proposed method shows better performance in terms of accuracy and stability.

Removal of pollutants in the exhaust system was an interesting field and it was inspired by the invention of modern Catalytic Converter (CATCO). The problem is low emission conversion from CO, NOx and HC to H2O, CO2 and NO2 due to low CATCO material conductivity. Therefore, the objective of this research is to investigate the conductivity and resistivity of FeCrAl material for CATCO that coated by combined technique of electroplating and ultrasonic methods. Nickel (Ni) plate as anode and FeCrAl as cathode. The distance between anode and cathode was adjusted at 25 mm. Ultrasonic was carried out using frequency of 35kHz. Ultrasonic and electroplating were conducted for several variation times of 15, 30, 45, 60 and 75 minutes. Drying process was performed after electroplating process at temperature of 600C for 12 hours. The conductivity and resistivity analysis will be conducted using 4 point probe machine. Resistivity and conductivity analysis show that the smallest resistivity and highest conductivity has been observed at UB+EL 30 minute for 2.67E+03 ohm-cm and 3.75E-04 S/cm, respectively. UB samples has lower resistivity and higher conductivity than EL, and UBdEL samples. It may caused by surface roughness of the FrCrAl material that embedded during the coating process.
