This research also investigated the chemical composition of kaolin clay and RHA used for the interlocking bricks. The mortar used was designed based on the concrete mix proportion of 1:2:3 but removed the coarse aggregate. The water-to-cement ratio utilized was 0.6. Each design mix comprises a combination of kaolin clay and RHA at 5%, 10% and 15% by the total weight of cement and sand, respectively. This paper demonstrates the chemical elements of the kaolin clay and RHA and reports the density and compressive strength of the interlocking bricks comparedto control samples. The results indicate that the density and compressive strength of the interlocking bricks decreases as the percentage of kaolin clay and RHA increases. The design mix containing 5% kaolin clay and RHA showed the highest density and compressive strength at 28 days, but the values were smaller than the control mix.In comparison to the control mix, the finding is as follows. At 28 days, the range of density reduction from day 3 for all mixes is between 16 to 25%. Meanwhile, the compressive strength of all mixes decreased by more than 65%, measured in the same duration. The result also showed that silicon dioxide (SiO2) contributes the most significant chemical element in kaolin clay and RHA. Kaolin clay contains almost 65% of SiO2, while RHA holds more than 90% of SiO2.","PeriodicalId":14189,"journal":{"name":"International Journal of Integrated Engineering","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43430930","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}

However, the permanent deformation performance only focuses on the surface course and neglected the influence of middle layer and base course. The present study investigates the permanent deformation characteristics of four (4) different configurations of flexible pavement and analyzes the contribution of AC surface and AC base course to the total permanent deformation of AC layer as the response to various truck’s speed, hauling loads, and loading cycles. Finite element modeling was performed to evaluate critical locations below the tire tread of single unit two-axles truck with the greatest magnitude of permanent deformation and to determine the optimum configuration of flexible pavement by considering the linear viscoelastic behavior of two types of AC mixtures. It can be concluded that the largest permanent deformation is measured below the right edge of the outer tire. The contribution of AC surface course on the total permanent deformation due to the increase in truck’s speed is only about 14.81% to 16.39%, while the contribution of AC surface course on the total permanent deformation due to the increase in truck’s hauling loads as well as the increase in the number of passing trucks is only around 14.76% to 16.44%. On the other hand, the contribution of AC base course on the total permanent deformation due to the increase in truck’s speed from is reaching 83.61% to 85.19%, while the contribution of AC base course on the total permanent deformation due to the increase in truck’s hauling loads as well as the increase in the number of passing trucks is achieving 83.56% to 85.24%.","PeriodicalId":14189,"journal":{"name":"International Journal of Integrated Engineering","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47716479","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}

The Butler Matrix (BM) feed circuit is the most preferable candidate for the 5G mobile system since it can achieve multi beam radiationpatterns at the array antenna, provide structural compactness and produce good multi beams.The BM circuit is typically built on a single dielectric substrate. However, in this single-substrate structure, the micro strip line connecting several circuit elements in the BM spans over a large area, resulting in significant feeding loss in the millimeter frequency band.In this study, a compact size circuit configuration of BM is proposed, where the original single-substrate structure is modified into a two-substrate stacking structure. The via-hole is designed to connect the two substrates with minimal path loss. The BM is built for the 28 GHz band with four inputs and four outputs.The phase delay is optimized using via-hole to produce the phase difference of ±45º and ±135º. The coupling for the hybrid is -3 dB, while the transmission coefficient of -6 ± 3 is achieved from the BM structure and, the return loss (Sii) for both input and output ports are less than -10 dB. The two-substrate BM is combined with the rectangular patch antenna and the via-hole patch antenna in a planar configuration of 0.5 λ0spacing to obtain the radiation patterns. When the Port 1 through Port 4 of the BM are fed, four beams are created, with peak gains of 11.2 dBi, 9.87 dBi, 10.2 dBi, and 11.7 dBi, respectively, towards +16°, -35°, +39°, and -12°. The analysis includes the radiation performance from the ideal value and from the BM input. Three-dimensional representations of good multibeam radiation patterns are obtained after each input signal of the BM is fed","PeriodicalId":14189,"journal":{"name":"International Journal of Integrated Engineering","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44259668","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}

This village is located approximately 60 km away from Kota Kinabalu town center, and the journey takes around two hours by car. Despite its remote location and the challenging geographical surroundings of mountains, the village is conveniently situated near an existing catchment area. However, this village's current water distribution setup relies on outdated and inadequate tools, systems, and facilities, leading to water scarcity issues, particularly during drought periods. To address this problem effectively, a sustainable design consisting of a mini dam and a ramp pump was developed and implemented in this study. Combining these two elements ensures the rapid filling of the storage distribution tank and the provision of clean water to the residents. One noteworthy feature of this project is the utilization of a 2-inch Polyvinyl chloride (PVC) ramp pump, significantly reducing operational costs and eliminating theneed for fossil fuels. This design not only proves to be practical and sustainable but also encourages the active participation of the villagers. Despite financial constraints and technical challenges associated with the project's implementation in a remote location, the water upgrading initiative was completed within four months, thanks to the direct involvement of the community. As a result of this endeavour, a fully functional water distribution network using the newly designed system has been installed, ensuring a reliable water supply for the 200 villagers in Kampung Bongol.","PeriodicalId":14189,"journal":{"name":"International Journal of Integrated Engineering","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45581406","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}
