<![CDATA[Surface thermistors are being currently used in patient monitoring, including temperature monitoring among neonates. However, these thermistors are reported as being mechanically rigid. This review article aims to provide researchers with a guide to better design a flexible neonatal temperature monitoring sensor. A literature search was conducted to obtain available literature on temperature sensors with specific attention to designing flexible temperature sensors. The achievement of a flexible type thermistor for neonates requires a basic understanding of the thermistor. Also, the conducting polymer material being used and the rationale for their placement. The updated technology in thermistors should be made flexible for the ease of neonates during monitoring. Careful considerations for the design and conduct of flexible temperature sensor research as outlined in this review would help to enhance the quality and comparability of future research studies. Considerations for efficient neonatal temperature monitoring and protection include accuracy, sensor's size, weight, material, and sensor placement. Flexible sensors could be the alternative to conventional bulky and stiff temperature sensors.]]>

<![CDATA[A magnetorheological is a new generation of smart materials in active mechanical vibration and shock control applications. This article is based on a comparative experimental study of the dynamic properties of magnetorheological elastomers (MRE) and magnetorheological fluids (MRF), whose damping and stiffness are controlled simultaneously by applying magnetic field intensity. The dynamic visco-analyser and rheometer were used to test the behaviour of MRE and MRF. The response of both materials depends on the amplitude due to shear strain. The experimental results clearly show the difference between the dynamic properties of MRE and MRF. More specifically, MFRs have high damping with low stiffness; on the other hand, the MRE has average damping with outstanding rigidity. These results help designers achieve more efficient and reliable structures in various engineering fields, such as buildings and mechanical applications.]]>

<![CDATA[Perspex has been known for a long time as a polymeric material, and it has been used for a large number of electrical and non-electrical applications. The present work was carried out to investigates the ageing mechanism of perspex material under a high electric field. The electrical treeing phenomenon was studied using perspex samples with electrodes of a pin-to-plane configuration. The growth of an electrical tree in Perspex was measured and analysed with the aid of an advanced microscope, equipped with a high-resolution camera and connected to a personal computer. Several distinct stages were assigned to characterise the electrical tree development. The area occupied by the electrical tree channels was calculated using equal-area squares. This approach was employed to measure the growth rate of electrical trees under dry and wet conditions. The tree construction, shape and growth speed were studied and analysed to distinguish between treeing phenomenon under wet and dry conditions of fabricated perspex specimens. The absorption of water has increased the tree growth inside the samples, and ions with water have accelerated the breakdown process. The findings of this study are essential to improve the performance of perspex material, which is widely used in a variety of applications for both energy and non-energy purposes.]]>

<![CDATA[In waste treatment and water management issues, electrocoagulation (EC) is the most cost-effective and environmentally friendly option. In the study, EC treatment of distillery spent wash was carried out using new electrodes packed with aluminium foil scraps. These metal scraps were packed in a mesh to function as anode and cathode electrodes. Electrochemical treatment was carried out for 150 minutes, and samples were analysed regularly to determine the colour and chemical oxygen demand (COD). The impact of operating parameters such as pH, applied current, electrolysis time, agitation speed, and electrode distance on colour and COD removal was investigated. The EC processes were carried out in monopolar parallel (MP-P) and monopolar series (MP-S). The MP-S connection measured the potential difference between the amplified pair of electrodes, whereas the output signals in the MP-P connection were formed by several input electrodes, resulting in a high removal rate. The results indicated that the MP-P relationships enhance the COD removal rate by 4.16 to 8.06 %. An optimum chemical oxygen demand degradation is 77.29 % at pH 3, and decolourisation is 76.55 % at pH 8.3. TDS is reduced to a maximum of 58.32 %, while sulfate and chloride are reduced to 64.72 and 20.44 %, respectively.]]>

<![CDATA[The paper describes the performance of a spark-ignition engine at various fuel octane numbers. This study was realised using a 150cc automatic motorcycle with a compression ratio of 10.6:1. The experiments were conducted on three types of gasoline with different research octane numbers (RON), namely 88, 90, and 92. The torque and power of the engine were evaluated using a dyno test, while fuel consumption was simultaneously monitored during the experiments. The data were then collected and analysed using Motorcycle Communication System (MCS). The MCS measurements indicated that fuel with RON 92 allows the vehicle to reach the top speed and rotation at a gas opening angle of 25° - 79°. Applying fuel with the proper octane number in an engine with a particular compression ratio can maintain optimal engine performance. Decreasing the fuel's octane rating from the recommended conditions based on the engine specifications causes a decrease in engine performance. Torque and power tend to drop, and fuel is not economical.]]>
