    K-means clustering algorithms of wireless sensor networks are potential solutions that prolong the network lifetime. However, limitations hamper these algorithms, where they depend on a deterministic K-value and random centroids to cluster their networks. But, a bad choice of the K-value and centroid locations leads to unbalanced clusters, thus unbalanced energy consumption. This paper proposes X-means algorithm as a new clustering technique that overcomes K-means limitations; clusters constructed using tentative centroids called parents in an initial phase. After that, parent centroids split into a range of positions called children, and children compete in a recursive process to construct clusters. Results show that X-means outperformed the traditional K-means algorithm and optimized the energy consumption.

    In this work, the influences of different concentration of sodium hydroxide (NaOH) (3, 6 and 9 wt.%) on the flexural and impact properties of linear low-density polyethylene / date seeds (LLDPE/DS) composites were examined. The LLDPE / DS ratio was fixed at 90/10 wt.% and the size of DS particles was measured at 125 - 250 micro m. The process used to synthesize the composites id extrusion followed by injuction molding process. Results showed that the presence of NaOH particularly at 6 wt.% concentration has improved the flexural and impact properties of the composite. This is due to bonding of the date seeds particles with the LLDPE matrix that reflected posativelly on the mechanical properties of the composite. However, the using of high NaOH concentration (9 wt.%) has shown an opposite trend, the increasing of surface roughness of the fiber after 9% NaOH treatment has reduced the flexibility of the composite and made it stiffer and more rigid, which in turn made it easy to break during mechanical test.

    The diversities of contractual terms in construction projects leads to a diversified contractual interpretation in one project. In the long term, the contractual discrepancies would result the project suffered from the dispute. Given the circumstances of measurement contracts, which refers to re – measurement or measure and value contracts are normally used when the quantity of the project can’t be describe in the exact amount. In the construction projects that involving complicated design, the difficulty may rose from the initial stage of architectural features. Often, the re-measuring’s fatality occurred when the elements finishes in the building has been over claimed by the contractor. Even so, the uncertainties of client’s instruction have always contributing to the excessive utilization of the fancy finishes in the construction projects. As a result, a dispute ascended due to payments, claim and work done issue. Site re-measurement can be done. However, in regard to almost completed building construction, the site re-measurement may get difficult as human can’t reach the building that has been constructed. Thus, issues on safety and accuracy may followed. Advance technology has provided the ability to implement the building survey without risking of manpower which is using the application of Unmanned Aerial Vehicle (UAV). Therefore, the research is carried out to identify the attributes of UAV application in roof re – measurement in building works and investigate the implementation of the UAV application. Using the literature search, the attributes of UAV application has been identified and the prototype case study has been selected to investigate the process of UAV application for roof site re-measurement. The results indicated that the utilization of UAV application is feasible as the tools for re – measurement of building works as the issues on the safety and accuracy are safeguarded.

    This paper introduces the concept of a variable arm for a quadrotor which is able to perform the manoeuvrability of the quadrotor by changing the arm length’s. The variation in arm’s length affects the bending moment generated by the thrust force, resulting in the tilting and movement of the quadrotor. The primary goal of this project is to develop a quadrotor with an adjustable arm length to control its manoeuvrability effectively, thus minimizing the need for additional thrust force during flight control. The study focuses on designing a quadrotor with the capability to extend or retract its arms. The proposed concept relies on altering the bending moment through the variable arm to control the quadrotor's manoeuvrability. A quadrotor equipped with a variable arm was successfully designed and tested, with its performance evaluated in executing agile maneuvers. The experiment demonstrated that the variable arm induced body rotation in the quadrotor, effectively regulating its manoeuvrability and the study validates the potential of the variable arm approach for controlling quadrotor movement.

    This paper discusses the development of an antenna tracker project focused on evaluating a 2.4 GHz Yagi Uda directional antenna connected to an NRF24L01 transceiver. It employs a gear reduction system for precise yaw and pitch control using two servo motors. The tracker calculates rotation angles using the Haversine formula for coordinates and inverse tangent trigonometry for elevation. Experiments took place in an open area with a stationary Ground Control Station (GCS) and a moving Unmanned Aerial Vehicle (UAV) to assess performance. The experiments comprised three tests: first, GCS without the Yagi Uda antenna or tracker; second, GCS with the Yagi Uda antenna but without the tracker, positioned along a 30-degree angle away from the transmitter; and third, GCS with both the Yagi Uda antenna and the tracker. The UAV gradually moved away from the tracker in 5-meter intervals until data loss occurred. The test results are based on received coordinates, distance, temperature, humidity, and data loss. Among the three tests, Test 3 demonstrates the best outcome, where the Yagi Uda antenna successfully receives data up to 180 meters before experiencing data loss.

    This paper introduces a smart water meter that utilizes the capabilities of the Internet of Things (IoT) to automate the collection of meter readings. The primary goal of this project is to create an IoT-based device for reading water meters, while simultaneously developing a compatible mobile application. Instead of relying on manual meter reading, which requires human effort, this project proposes the use of an IoT-enabled water meter to collect the data automatically. The device employs a camera and Convolutional Neural Network (CNN) for image processing, making it easy to detect the meter reading accurately. The IoT system architecture involves the use of an ESP32 CAM for data collection, a laptop as a gateway, and the Message Queuing Telemetry Transport (MQTT) protocol for data transfer. The collected data is stored in Firebase's real-time database, and the mobile application is designed to monitor and analyze the data. A functional prototype of the device is constructed and tested in a housing area. The collected data is then monitored through the developed mobile application. Lastly, the data is analyzed to assess the suitability of the proposed method, and recommendations for future improvements are provided.
