Dynamic Analysis of Structures Considering Waffle Slab with and without Drops and Beams
Abstract: The seismic performance of a structure is a fundamental and vital aspect of structural engineering, carrying significant importance in ensuring safety and stability. This study investigates the dynamic behavior of structures employing waffle slab designs with and without drops and beams, focusing on varying panel sizes. Commercial buildings, each comprising 12 stories with heights of 3.5 meters, were analyzed using the Response Spectrum Method in seismic Zone III, utilizing ETABS …

Low Velocity Impact Behaviour of Corrugated Foam Sandwich Panel
Abstract: Composite sandwich structures, renowned for their high flexural stiffness and low weight, are widely used across industries such as aerospace, automotive, and marine. However, their durability can be compromised by impact-related damages, which affect both the core and face sheets. This study explores the performance of corrugated sandwich panels compared to conventional designs under low-velocity impacts. Using a drop weight impact testing machine, panels made from polyurethane foam cores and …

Cooling test's impact on photovoltaic solar panel systems
Abstract: Temperature changes have a massive effect on the performance of photovoltaic (PV) solar panels that are currently extensively used for the conversion of solar power into electrical energy. The output of solar systems is limited, especially in hot climates, as heating of the panel causes output voltage and efficiency to drop. The paper explores the effects of cooling on the quality and performance of photovoltaic (PV) solar panels. In this …

Heat Sink-PCM Device for PV Efficiency Improvement
Abstract: This paper is focused on the development of a second stage of a previous work where the PV panel efficiency is improved by using a hybrid system made up of a PCM attached to the rear side of the panel. This evolved stage incorporates a heat sink unit to improve the distribution of the heat removed from the panel; this improvement reduces the elapsed time to reach the steady state …

China’s Economic Performance (2020–2024): A Sectoral Index Analysis
Abstract: This study applies Laspeyres, Paasche, and Fisher ideal indices to China’s official 2020–2024 price and quantity data, quantifying sectoral inflation and real growth in agriculture, manufacturing, services, exports, and investment. Results show manufacturing experienced mild deflation (Laspeyres ≈ 98.7, implying ≈ 1.3% overall price decline) with a slight real output drop (~6.1%). A key driver was a sharp 21.4% fall in electric vehicle unit prices, despite +523% volume growth. Services …
