Abstract: The paper aims to present some new hydropower technologies that use the hidden hydro potential of small and very small head, the investigation of locations with significant hydropower potential such as urban water supply systems, irrigation systems and small rivers in Romania (including small dams and non-energy dams) but also of other possible locations with significant hydropower potential. Even if this hidden hydropower potential is not significant in terms of contribution to the national energy system (SEN), this potential could be useful for reducing electricity demand in various locations/area within smart cities, including raw water treatment facilities and waste water. Also, the efficient exploitation of this hidden hydro potential could contribute significantly to rural electrification......

Abstract: Steel structures in India are predominantly conventional type using prismatic hot rolled sections yielding to higher tonnage. Cost of steel is increasing day by day and use of steel has increase in the construction industry. Hence to achieve economic sustainability it is necessary to use steel to its optimum quantity. In steel structure design the Pre-engineering building (PEB) system is a modern technology that provides economical, eco-friendly, and sustainable structures. Pre-Engineered for frames and cold formed sections for purlins and girt which greatly reduces the tonnage resulting in lighter and economical structure. This paper mainly focuses on the present relative study of conventional and PEB steel Aircraft Hanger with the help of finite element-based software STAAD.Pro. Analysis is done using STAAD.Pro software and members are designed manually as per the relevant code requirements and detailing diagrams are executed in AutoCAD.

Abstract: In almost all the cases of vehicle accidents, the basic reason cited is failure to apply the brakes at the right time. If the brakes are applied at the right time the accidents can be prevented. Automation can assure higher reliability of braking as compared to fully manual braking. The use of pneumatic system can prove to be useful in automation due to its simplicity and ease of operation the aim is to design and develop a system based on automatic control of vehicle. So, we aim to design "Intelligent Braking system with Pneumatic Bumper".

Abstract: The growth and development of the global economy makes a significant contribution resulting in increasingly uncontrolled disposal of wastewater which results in increasing environmental problems associated with the provision of clean water. Water plays a major role in most household and industrial processes. This research concerns water filtration using membrane technology with Polyvinylidene Fluoride (PVDF) polymer mixed with Tin(IV) Dioxide (SnO₂). It aims to analyze the microstructure formed through Scanning Electron Microscopy (SEM) testing and determine the mechanical.......

Abstract: 3D printing, as an emerging manufacturing technology, has the characteristics of on-demand printing and inventory reduction, which to some extent reduces carbon emissions during product production. To study the carbon emissions during FDM molding process, the entire lifecycle theory is used to divide the molding process into stages, and a carbon emission quantification model is established using the carbon emission factor method; The Box Behnken experimental design method was used to conduct carbon emission experiments, selecting four factors: filling rate, printing speed, layer height.......
