Lack of clean drinking water in rural areas is a huge problem during the occurrences of floods and other environmental disasters. Often, it takes a long time to transport potable water to these areas resulting in health issues to the local residents. In this research, a solar power based water purification system using a cartridge heater to produce clean drinking water in flood affected areas or remote areas where potable water is difficult to obtain is proposed. This water purification system uses a distillation technique, with an automatic valve which fills up a tank and heats up the water. The steam is captured and flowed into a clean water holding tank. This project could provide a good solution for providing clean drinking water to areas affected by floods.

The substrate of the flexible printed circuit board (FPCB) introduced a new segment in surface mount technology (SMT) microelectronic industry to replace the conventional rigid printed circuit board (RPCB). Superior in flexibility and thin physical accommodate the necessity of present electronic devices. However, a far more critical issue would lie in the soldering connection between components and FPCB in the thermal reflow soldering atmosphere. These works investigate the factor of Reynold numbers (Re) and a conveyor speed of FPCB surface with the incorporation of single BGA. For this simulation purpose, the model was performed using finite volume (FV) based and finite element (FE) based, coupled simultaneously in FLUENT system coupling. Findings indicate both effects have major respond on FPCB surface and soldering connection at maximum deflection and von Mises stress, respectively. Moreover, the Re showed dominant influence towards soldering connection over conveyor speed.The substrate of the flexible printed circuit board (FPCB) introduced a new segment in surface mount technology (SMT) microelectronic industry to replace the conventional rigid printed circuit board (RPCB).

Geopolymer is a new type of sustainable material which is produced by using industrial by-product. Recent articles showed that geopolymer materials have good machining property. However, the rubberised fly ash geopolymer (RFAG) has not been well investigated. Besides, the machining optimization also covered on natural fly ash geopolymer. So, this research was carried out to investigate the best parameter settings of machining RFAG material with respect to tool wear and the most significant parameters with respond to tool wear. The RFAG samples were machined by CNC milling machine. The cutting speed, feed rate and depth of cut were selected as the cutting parameters. Orthogonal arrays by using L9 of Taguchi method, analysis of variance (ANOVA) and the signal-to-noise ratio are employed to find the optimal levels of the significant factor affecting and to analyse the cutting parameters on tool wear. The results showed that cutting speed was the significance factor affecting tool wear. The validation test was carried out and the minimum flank wear value (0.0745 mm) was obtained. This research proves that rubberised fly ash geopolymer (RFAG) is machinable and the result collected will be expanded the application of rubberised geopolymer in the industrial sectors. The mass production of RFAG will help to reduce the waste product (fly ash and rubber waste) in order to save the environment. The success of this result is significant so that RFAG can replace current material used in common machining activities.Geopolymer is a new type of sustainable material which is produced by using industrial by-product.

Dye-sensitized solar cell technology commonly known as DSSC appears to be very well suited for integration into greenhouse glazing systems due to their characteristics of transparency, color tuning and manufacturing directly on glass substrates. The condition and performance of this material are subjected mainly on the location of installation where the sun radiation is a crucial factor to be considered. This study analyses the behavior of dye solar cells in real-life tropical weather conditions from a varying weather of mildly warm to hot sunny and to wet rainy conditions. Four units of experimental Red colored DSSC module (DSS SERIO 3550W19), Solaronix, Switzerland have been installed in series at the Faculty of Engineering, UPM Serdang, Selangor, Malaysia. The observation is based on the Solar Module Analyzer (PROVA 210) data logging device for 5 days at 10 min intervals. The effect of different weather conditions on the cell performance is quantitatively investigated by using correlations coefficients of sun radiation (G) to cell performance (I, V parameters) which produces the expected annual energy yield.Dye-sensitized solar cell technology commonly known as DSSC appears to be very well suited for integration into greenhouse glazing systems due to their characteristics of transparency, color tuning and manufacturing directly on glass substrates.

In order to ensure a sustainable development by substantially reducing human contribution to accentuating the greenhouse effect phenomenon and exhausting natural resources, it was necessary to develop various installations for capturing, storing and transforming the energy produced by renewable sources into electricity. At the same time, efficient resource use is one of the most important prerequisites for sustainable economic growth and the transformation of waste into secondary raw materials forms the basis for systems that promote the circular economy. In this sense, it is necessary to research and apply new technologies for the integration of recycled materials into complex systems of green energy production. The present paper describes the preliminary results obtained from the laboratory tests which involved the use of recyclable materials in order to produce electricity based on solar energy.In order to ensure a sustainable development by substantially reducing human contribution to accentuating the greenhouse effect phenomenon and exhausting natural resources, it was necessary to develop various installations for capturing, storing and transforming the energy produced by renewable sources into electricity.

Presently practitioners in businesses are faced with issues related to the implementation of sustainable practices. Accordingly, practitioners in businesses need to make decision based on their current practice to verify if present practice considers the environmental, economic, and social elements of sustainability. But, at the moment businesses utilizes manual specification based ranking and benchmarking approaches to ascertain that practitioners consider the natural environment and society as they make profit. Nevertheless, there is need for an autonomous method of measuring firms sustainable practice implementation. Therefore, this paper develops a persuasive agent’s model to measure; benchmark and rate businesses current practice based on review of prior sustainability studies. The persuasive agents’ model comprises of sustainable practice operations question, alternatives, and persuasive agents measurement procedures. Respectfully, findings from the study depict how the integrated persuasive agents autonomously measure, benchmark, rate and provide recommendations to practitioners. This study provides implications on how businesses can improve their business operation towards social, economic and environmental sustainable practice implementation.

This paper is aimed to simulate the pin transfer process for solder paste to determine the viability of this technique to perform as an alternative to other solder paste deposition technique such as stencil printing. A model of fluid-structure interaction is designed to model the pin transfer process where the pin dipped into the solder bath and picking up the solder paste. Based on the previous study, it is found that the design of the pin nozzle exhibits certain limitations which is the consistency of the volume of solder paste transfer as well as the desire texture of the solder paste displace onto PCB pad. Different size and type of components require a designated pin to perform the pin transfer process. The development of the pin nozzle design is a time consuming process. An introduction of the pin transfer process simulation model managed to facilitate the designing process and reduce the time taken. In this research, the process of dipping the pin nozzle into the solder paste bath is study with dynamic mesh. The dipping process of the pin nozzle in simulation required a fine meshing to ensure the high accuracy of the simulated outcome. Moreover, the optimum time step size for the pin dipping process simulation is determined in the study. Generally, the implementation of the pin transfer process simulator, the design process of the pin can be improved with an increasing efficiency and productivity process which is beneficial to the industry.This paper is aimed to simulate the pin transfer process for solder paste to determine the viability of this technique to perform as an alternative to other solder paste deposition technique such as stencil printing.

Generally, the implementation of the pin transfer process simulator, the design process of the pin can be improved with an increasing efficiency and productivity process which is beneficial to the industry.This paper is aimed to simulate the pin transfer process for solder paste to determine the viability of this technique to perform as an alternative to other solder paste deposition technique such as stencil printing. A model of fluid-structure interaction is designed to model the pin transfer process where the pin dipped into the solder bath and picking up the solder paste. Based on the previous study, it is found that the design of the pin nozzle exhibits certain limitations which is the consistency of the volume of solder paste transfer as well as the desire texture of the solder paste displace onto PCB pad. Different size and type of components require a designated pin to perform the pin transfer process. The development of the pin nozzle design is a time consuming process. An introduction of the pin transfer process simulation model managed to facilitate the designing process and reduce the time taken. In this research, the process of dipping the pin nozzle into the solder paste bath is study with dyn...","PeriodicalId":112912,"journal":{"name":"APPLIED PHYSICS OF CONDENSED MATTER (APCOM 2019)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128018016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Injection molding is the advance technologies in manufacturing plastic parts in modern industries nowadays. The quality of the moulded parts are highly depends on parameter settings of injection moulding process. In this research, there are 4 process parameter used which are melt temperature, mould temperature, cooling time and packing time. By using Autodesk Moldflow Insight (AMI) 2012, the recommended process parameter settings are melt temperature of 230 °C, mould temperature of 60°C, cooling time of 15.60s and packing time of 31.34s. These settings yield warpage value of 0.4295mm. From Response Surface Methodology (RSM), the warpage value optimised to 0.412728mm with melt temperature increases to 230.32 °C, mould temperature increases to 63.04 °C, cooling time increases to 15.77s and packing time decreases to 28.25s. From the validation test, the percentage error obtained is 0.0075%, which is very little different with RSM value. So, the results of process parameter settings in RSM is valid.
