Acoustic Emission (AE) techniques are used for the structural health monitoring (SHM) of civil, aeronautic and aerospace structures.
Introduction The use of composite materials has extensively increased in the design of existing engineering structures, which also increases the analysis complexity of such structures.
They address important issues in the field of guided-wave-based damage identification and structural health monitoring presenting the modelling, analysis and experimental investigations of elastic wave propagation in engineering structures made of isotropic or composite materials.

EVALUATE RECENT NUMERICAL METHODS FOR LONG-TERM SIMULATION TO STUDY THE EFFECT OF DIFFERENT SHAPES OF THERMAL BRIDGES IN WALLS Issa Omle1,a* and Endre Kovács2,b 1Department of Fluid and Heat Engineering, Faculty of Mechanical Engineering and Informatics, University of Miskolc, 3515 Miskolc, Hungary 2Institute of Physics and Electrical Engineering, Faculty of Mechanical Engineering and Informatics, University of Miskolc, 3515 Miskolc, Hungary aissa.j.omle@gmail.com, bkendre01@gmail.com Keywords: List Heat loss, Numerical methods, Transient heat transfer, Thermal bridges, Long-term simulations.
Our solution to a real-world engineering challenge involves investigating thermal bridges of different forms inside multilayer walls of buildings exposed to environmental factors specific to Hungary's climate, such as the outside temperature and sun radiation, to improve energy efficiency.
Because thermal bridges have a significant impact on reducing the energy efficiency of buildings, heat loss, air quality, and durability, needing structural and thermal design integration, architects, civil engineers, and those in the insulation materials sector should be especially interested in the thermal bridge models that are being studied [1].
The validation experiments on more than a thousand real-world samples supported the validity of such correlations, enabling a simple and useful examination of thermal bridges in current structures.Since many heat transfer applications within engineering domains incorporate many thermal models, the analysis of transient heat transfer is an important problem that is often addressed utilizing numerical rather than analytical methodologies.

Renewable Energy for Sustainable Socio-economic Development in Developing Countries: A Case Study of Sub-Saharan Africa Mukhtar Bello Department of Chemical Engineering, Ahmadu Bello University, Zaria, Nigeria.
This initiative seeks to engage governments, companies, and other civil society actors to achieve three goals by 2030: universal access to modern energy services, reducing global energy intensity by 40% and increasing renewable energy use globally to 30% of total primary energy supply.
Thus, global partnership among governments, civil society, private sector and development partners is crucial in the successful deployment of renewable energy to increase energy access for sustainable socio-economic development.
For example, in December 2012, an engineer (French national) working with VERGNET Company on Katsina wind power project in Nigeria was kidnapped, which has brought the project to a temporary stand still.

Concrete is the most widely used building material and civil engineering structure material in various ways, it is difficult to collect relevant data, and most of concrete is only used as backfill, recycled aggregate and raw material of recycled building products after being wasted.
