Critical Human Resource Management Challenges in the Large-Scale Building Construction Industry of Sri Lanka An RII-Based Analysis
Human Resource Management (HRM) plays a vital role in improving workforce performance and organizational productivity in the construction industry. However, the Sri Lankan building construction industry continues to experience several HRM challenges that affect project performance and employee management. This study aims to identify the critical Human Resource Management challenges faced by the Sri Lankan …
A REVIEW OF LOW-COST EMBEDDED ACOUSTIC AND VIBRATION-BASED ENGINE MISFIRE DETECTION FOR REAL-VEHICLE
Engine misfire is a combustion fault that results in one or more cylinders not contributing to the torque. It negatively affects the drivability, consumes more fuel, produces higher emissions and can cause damage to exhaust after-treatment systems if not detected. Conventional on-board diagnostics are primarily based on crankshaft speed variation, which is useful for regulatory …
Practical Demonstration Improves Assessment Performance in Farm Machinery Education A Quasi-Experimental Study
The persistent emphasis on theory-led instruction in many engineering technology programmes raises a practical question: does direct, hands-on exposure to equipment measurably improve how well students understand and apply what they have already studied. This study evaluated the immediate effect of a practical demonstration on assessment performance among 75 final-year Engineering Technology undergraduates enrolled in …
Impact of Modern Non-Linear Loads on Reactive Power Demand and Power Quality A Comparative Review of STATCOM Topologies for Distribution Systems
The growing share of power-electronic-based loads on low-voltage distribution networks — electric vehicle (EV) chargers, variable frequency drives (VFDs), switched-mode power supplies (SMPS), LED lighting drivers, and data-centre infrastructure — is changing the reactive power profile that utilities must manage. Unlike conventional linear loads, these devices draw non-sinusoidal current, depress the effective power factor, and …
Mechanical Testing of Materials Understanding Stress-Strain Relationships
Mechanical testing plays a critical role in the selection of materials by providing insights into their strengths and weaknesses. This paper examines the relationship between stress and strain, emphasizing fundamental concepts for analyzing material failures. While the uniaxial tensile test is the most widely used method for determining key properties such as stiffness and strength, …
