In this study, the relation between macroscopic parameters (speed, flow, density, occupancy) and microscopic (lateral clearance, average gap, space headway, lateral movement duration, overtaking time, distance, relative speed) is evaluated by considering vehicle-type-dependent factor using trajectory data collected at a five-lane urban merge non-merge sections in Malaysia. Traffic extractor software utilized to extract speed, of vehicles both highway. Both SPSS MATLAB were used conduct...

Abstract In recent times, Additive Manufacturing (AM) has been applied rapidly in almost all fields. This study was conducted to apply the additive manufacturing into an acoustic application by 3D printing Micro-Perforated Panels (MPP) through Fused Deposition Modelling (FDM) made of Polylactic Acid (PLA) reinforced with wood fibers. MPP were fabricated altering its perforation volume. Later, effect volume on absorption measured using two-microphone impedance tube method as per ISO 10534-2...

The world of academia is fast revolving fostering a need for rapid use innovative teaching pedagogies and tools to enhance the effectiveness learning activities within classroom. Video recorded lectures that enable direct communication with learners have been recently exploited by more technology savvy academics. Mobile has introduced new kind enabling them learn anytime anywhere. purpose this paper study effects mobile had on achievement attitude students Foundation in Engineering programme.

Natural fibers and their composites are being widely used in almost all the applications this modern era. However, properties of natural have to be enhanced order compete with synthetic fibers. This review paper opens up additive manufacturing, as a novel method for developing an acoustic panel using fiber mechanical acoustical properties. approach will help replace synthetic-based absorbers biodegradable composite panels applications. also covers, poly(lactic acid) polymer matrix its...

The effects of sintering profiles on the Zirconia Toughened Alumina (ZTA) composite containing 0 vol% Y-TZP (pure alumina) to 20 content prepared by a method known as two-stage were investigated. heating rate was set between 10°C/min 20°C/min, T 1 1400°C 1500°C, 2 at 1350°C and holding time 12 hours. samples’ microstructural properties mechanical properties, including bulk density, Vickers hardness, Young’s modulus fracture toughness, evaluated. Based data obtained, ZTA composites with 10...

Additive manufacturing (AM) of Natural Fiber-Reinforced Composites through Fused Deposition Modeling is receiving much attention in recent years. AM very appealing for complex shape structures that can be inconvenient to produce by other methods. In this study, the acoustic panel made from polylactic acid reinforced with wood fiber composite was 3D printed varying its thickness and infill density. The sound absorption coefficient measured using an impedance tube. thin back air gap found...

The lane-changing behavior of different types vehicles at the merging section an urban road is assessed by using a new model proposed in current work. known as MOBIL (minimizing overall braking induced lane changes) modified and combined with intelligent driver (IDM) to implement rules for vehicle classes applying politeness vehicle-type factors. It noted that heterogeneity surrounding during lane-changing, which common developing countries, not considered most existing models. preceding...

This paper presents the development and performance of micro-perforated panels (MPP) from natural fiber reinforced composites. The MPP is made Polylactic Acid (PLA) with Oil Palm Empty Fruit Bunch Fiber (OPEFBF). investigation was by varying density, air gap, perforation ratio to observe effect on Sound Absorption Coefficient (SAC) through experiment in an impedance tube. It found that peak level SAC not affected, but frequency shifts lower when density increased. phenomenon might be due...

The effect of Iron Oxide (Fe2O3) addition from 0 to 0.8 vol% on Zirconia Toughened Alumina (ZTA) with 10 Yttria-Tetragonal Polycrystals (Y-TZP) produced through conventional pressureless two-stage sintering (TSS) were investigated. ZTA samples sintered first stage temperature T1 ranging 1400°C and 1550°C a heating rate 20°C/min followed by second T2 1350°C hold for 12 hours. samples' then evaluated its' microstructure mechanical properties such as grain size, bulk density, Vickers hardness,...

Alumina-Y-TZP composites between 0 to 25 vol% Y-TZP content produced via conventional two-stage sintering with T 1 ranging 1400°C and 1550°C, heating rate of 20°C/min, followed by 2 1350°C 12 hours dwelling time. The microstructure, density, Vickers hardness (H V ), Young’s modulus (E) fracture toughness (K IC ) the sintered samples were then evaluated. It is observed that all up 10 achieved > 98% T.D. as increases. Samples above resulted in a significant decrease density hardness. ≤ at...

Small amount of Copper Oxide (CuO) ranging between 0 vol% to 0.8 vol % were added into Zirconia Toughened Alumina (ZTA) containing 10 Yttria-Tetragonal Polycrystals (Y-TZP) and its effect on ZTA's microstructural mechanical properties investigated. The ZTA samples prepared through two-stage sintering (TSS) with first stage temperature T1 set in the range 1400°C 1550°C whereas second T2 at 1350°C followed by 12 hours holding time. sintered evaluated grain size, bulk density, Vickers hardness,...

Sintering parameters are undoubtedly among the many factors that influence mechanical properties and hydrothermal ageing resistance of tetragonal zirconia ceramics. In this research, effect using short holding times i.e. (1 min., 30 min. 1 hour) as compared to conventional 2 hours during sintering 3 mol% Yttria Tetragonal Zirconia Polycrystals (3Y-TZP) on were systematically investigated. The research revealed time minute sintered at 1400 o C yielded a high relative density (above 95%...
