Stability Criteria for the Generalized El Borhamy-Rashad-Sobhy Equation
Full text linkThis article is concerned with the study of stability criteria for one of the generalization form of El Borhamy-Rashad Sobhy equation, which is a linear second-order ordinary differential equation with periodically time varying coefficients. Many engineering applications can be represented by this generalization, for instance, including the modeling of RLC circuit with time varying inductance, resistance and capacitance, and the vibration of a stretched string, whose mass per unit length is periodic, under a periodic motion. An approximate solution is derived by using the Wenhl-Kramers-Brillonin (WKB) approach. A method of constructing Liapunov function is employed to derive extra conditions for the asymptotic stability criteria. The construction of periodic solution is obtained by employing the harmonic balance method (HBM) using the truncated Fourier expansion. As a result of HBM, the stability charts for the different possible cases are constructed to show the effect of the model parameters on the stability domains. Numerical results are used to verify the corresponding deduced analytical ones

Experimental and Analytical Study on Shear Bond Behaviour of Lightweight Concrete Composite Deck Slab with Shear Connectors
Full text linkThis study investigates the bond strength between lightweight concrete and steel elements in composite deck slabs, with a focus on enhancing bond performance through the use of shear connectors. The primary objective was to improve the interface behavior between lightweight concrete and steel corrugated sheets by introducing shear connectors between the composite slab and supporting steel beams. Both experimental and analytical methods were employed. Experimentally, twelve lightweight concrete specimens were fabricated and divided into two groups: one without shear connectors and the other with shear connectors. Each group was further classified into specimens with long and short spans. These specimens were subjected to static and cyclic loads to evaluate their performance. The findings revealed that incorporating shear connectors improved bond strength by 20% to 78% compared to specimens without connectors. Additionally, short-span specimens exhibited 20-90% higher flexural strength than long-span specimens. The sliding movement was reduced by 20-40% in slabs with shear connectors, demonstrating enhanced ductility and sliding resistance. Analytical validation was performed using international codes, and the results aligned well with the experimental outcomes. The shear bond properties of lightweight composite slabs were determined using the semi-empirical m-k method, as specified in EN 1994-1-1:2004, confirming the reliability of the findings.
This study underscores the significant advantages of incorporating shear connectors in lightweight composite slabs, providing valuable insights for optimizing their structural performance

Performance and Emissions Characteristics of Multi-Cylinder Direct Injection Diesel Engine Fuelled with Diesel/Biodiesel and Toluene Additives
Full text linkThis study explores the impact of using a diesel, biodiesel, and toluene additive fuel blend in a multi-cylinder direct injection diesel engine, focusing on both performance and emissions characteristics. Biodiesel, made from renewable sources like vegetable oils, is often added to diesel to reduce reliance on fossil fuels and improve combustion due to its higher oxygen content. In this work, a 45% biodiesel blend (B45) led to significant reductions in particulate matter (PM) emissions by up to 40% compared to conventional diesel. Additionally, carbon monoxide (CO) and hydrocarbon (HC) emissions decreased by up to 30% and 25%, respectively, due to biodiesel\u27s cleaner combustion properties. However, biodiesel’s lower energy density compared to diesel, caused engine power to drop by 2-5% and increased fuel consumption by 3-6%, reducing overall engine efficiency. To address these drawbacks, toluene was added to the fuel blend. When toluene was added in a concentrations of 5-10% by volume, it increased the brake thermal efficiency (BTE) of the engine by 4-10%, offsetting the power losses associated with biodiesel. Toluene also improves fuel atomization, leading tofiner spray patterns and a more complete and efficient combustion process. This improved combustion process further reduces CO and HC emissions beyond what biodiesel alone could achieve. This improved combustion process further reduced CO and HC emissions beyond what biodiesel alone could achieve. Another advantage of toluene is its ability to enhance combustion stability, reducing cylinder-to-cylinder variations and improving knock resistance. However, a challenge when using biodiesel, particularly with toluene, is the potential increase in nitrogen oxide (NOx) emissions. Biodiesel’s higher combustion temperatures contribute to higher NOx formation, and while toluene enhances combustion, it may also raise these temperatures further, increasing NOx emissions by 10-20%. Therefore, precise tuning of engine parameters like injection timing and pressure is required to balance the benefits of improved performance and reduced CO, HC, and PM emissions with the potential rise in NOx emissions
