Published: March 2021

Abstract
The vapour compression refrigeration system is an important one among other thermal systems and consumes more energy. The efforts have been made in many ways to enhance the energy efficiency of refrigeration system from various points of view, including energy efficient refrigerants, replacing existing components, using phase change materials in the condenser and evaporator and adding nano-materials to the refrigerants. This work explores and describes the improvement of energy efficiency of the refrigeration system through the application of the phase change material between wall and coil of the evaporator cabin. The experimental results showed significant effects on system performance such as coefficient of performance increased by 7.1%, per energy consumption decreased by 6.7% and temperature variations were also relatively lower inside the freezer cabinet. This proposed concept would be useful in the event of power failures that are very usual in low grid reliability locations.

Abstract
The key goal of this research is to avoid road accidents. Most of the studies clearly show that the majority of incidents take place near certain places such as school areas, dining areas, etc. The purpose of the proposed system is, by signaling or warning through WI-FI, to avoid the accident in nearby areas. If the Bridge zone is narrower than 100 meters from vehicles, a mobile warning will be issued via the WI-FI network. The person reduces the vehicle speed following this indication. Just like if a school area closer to vehicles is within 100 meters, the cell phone will be alerted via WI-FI. The person reduces the speed of the vehicle after this indication. Like Fog, it gives message warning to mobile devices via the WI-FI area within 100 meters. The individual decreases the speed of the vehicle following this indication. This sign helps us to reduce road injuries. We use WI-FI, AT89S52, switches for this implementation. The Wi-Fi module is connected to the controller here in this project and can be controlled from any location at the Internet speed. The managed power supply for this project is 5V 500mA. For voltage power, 7805 three voltage terminal regulators are used. Full-wave bridge rectifier is used to rectify the 230/12V transformer secondary ac output.

Abstract
The electrocardiogram has the extensive diagnostic significance, and utilizations of ECG observing are assorted and in wide use. ECG signal after procurement contains noises, for example, power line impedance, instrumentation noise, external electromagnetic field obstruction, commotion because of arbitrary body developments and breath developments. These noises can be classified according to their frequency content. It is fundamental to decrease these unsettling influences in ECG sign to improve exactness and dependability. The bandwidth of the noise overlaps that of wanted signals, so basic filtering can’t adequately improve the signal to noise ratio. Current biomedical enhancers have an exceptionally high common mode rejection ratio. All things considered, accounts are often contaminated by residual power-line interference. Conventional simple and advanced channels are known to suppress ECG segments close to the electrical cable recurrence. This paper deals with design filter for ECG signal utilizing operational amplifier using Multisim.

Published: March 2021

Abstract
The levee stretch near Dataran Bandar Baharu was a part of the Kerian River Flood Mitigation Project (Phase 3) in Kedah to address frequent flooding problems at the area. It has been facing recurring levee failure despite several repair attempts in the past. As the research area was subjected to water level fluctuations, a numerical model using SEEP/W was analysed to study the effect of drawdown and seepage on the failed levee. Variables considered in this study include soil permeability, groundwater table and time dependent river water levels on the upstream side of the levee. The transient analysis carried out indicated that the levee was susceptible to failure due to the relatively high phreatic line within the levee during drawdown and a seepage face occurrence on the upstream side of the levee.

Published: March 2021

Abstract
Potential evapotranspiration (PET) plays a prominent part in hydrologic water cycle which is responsible for the water from the Earth’s surface travel back to the atmosphere. Climate change brought contradictory changes in PET which led to the inconsistency of PET trend globally. Hence, the present study carried out the trend of potential evapotranspiration using meteorological data from 7 different meteorological stations located in Peninsular Malaysia. Mann-Kendall and Sen’s slope estimator tests were employed in this article for PET trend analysis. Bayan Lepas experienced significant increasing trend for both FAO 56-Penman Monteith and Mahringer models during Southwest monsoon. For Mahringer model, significant increasing trends were observed at Ipoh and Pulau Langkawi stations during Northeast and inter monsoon 2, respectively. There were only a few meteorological stations experienced decreasing trend throughout the period. Although the combinations of increasing and decreasing PET trends were observed, it can be highlighted that majority of the PET time series exhibited increasing trend in Peninsular Malaysia.
