“…One of the AI applications is UAV which also popular with the name drone, is being the focal point of technologies for civilian dan military use lately for monitoring and surveillance purposes because of its attributes of quick deployment, adaptive elevation, and versatility (Barbosa et al, 2020). UAV offers high-resolution video or picture, flexibility of autonomous flight, and real-time data collection streaming that enables further exploitation for diverse use.…”

Artificial intelligence (AI) has impacted many sectors such as education, healthcare, political, social and economic that can give either positive or negative side effects. According to research by Accenture on the impact of AI in 12 developed countries, it concluded that AI has the potential to double annual economic growth by 2035. Another research by PricewaterhouseCoopers (PwC) claimed that global GDP could be up to 14% higher in 2030 as a result of AI. Since AI plays an important role in our daily lives, the awareness and knowledge about this technology must be updated from time to time. Therefore, the aim of this study is to analyze the awareness and knowledge on AI among accountancy students with the main intention to instil and develop their interest towards AI. For data collection, all accounting students in UiTM Tapah were selected to be respondents of the study that used questionnaires as the survey instruments. The results revealed that accounting students aware about AI with moderate knowledge about it. Nevertheless, majority of the respondents agreed that AI has greater impact and benefit people in many areas. The findings of this study provide some insights and value added in shaping the interest and knowledge especially among accounting students towards AI technology.

“…Applying electrically conductive polymer composites (CPCs) in FDM technology, some researchers have recently tried to develop sensors that are responsive to different stimuli such as chemicals including solvents, biological fluids, dopamine, serotonin, metals, vapors, mechanical flexing and liquid levels [ 21 , 22 , 23 , 24 ]. Kim et al [ 25 ] 3D-printed thermoplastic polyurethane (TPU) and TPU/multiwalled carbon nanotubes (MWNT) (a structural part and a sensing part, respectively) to fabricate a 3D multiaxial force sensor that could detect the submillimeter scale deflection and its corresponding force on each axis.…”

An increasing interest is focused on the application of 3D printing for sensor manufacturing. Using 3D printing technology offers a new approach to the fabrication of sensors that are both geometrically and functionally complex. This work presents the analysis of the 3D-printed thermoplastic nanocomposites compress under the applied force. The response for the corresponding resistance changes versus applied load is obtained to evaluate the effectiveness of the printed layer as a pressure/force sensor. Multi-walled carbon nanotubes (MWNT) and high-structured carbon black (Ketjenblack) (KB) in the polylactic acid (PLA) matrix were extruded to develop 3D-printable filaments. The electrical and piezoresistive behaviors of the created 3D-printed layers were investigated. The percolation threshold of MWNT and KB 3D-printed layers are 1 wt.% and 4 wt.%, respectively. The PLA/1 wt.% MWNT 3D-printed layers with 1 mm thickness exhibit a negative pressure coefficient (NPC) characterized by a decrease of about one decade in resistance with increasing compressive loadings up to 18 N with a maximum strain up to about 16%. In the cyclic mode with a 1 N/min force rate, the PLA/1 wt.% MWNT 3D-printed layers showed good performance with the piezoresistive coefficient or gauge factor (G) of 7.6 obtained with the amplitude of the piezoresistive response (Ar) of about -0.8. KB composites could not show stable piezoresistive responses in a cyclic mode. However, under high force rate compression, the PLA/4 wt.% KB 3D-printed layers led to responses of large sensitivity (Ar = −0.90) and were exempt from noise with a high value of G = 47.6 in the first cycle, which is a highly efficient piezoresistive behavior.
