The aerodynamic design of rotor blades is challenging, and is crucial for the development of helicopter technology. Previous aerodynamic optimizations that focused only on limited design points find it difficult to balance flight performance across the en... see more

Quercetin is a flavonoid from a group of polyphenolic flavonoid compounds. Quercetin can be used as an alternative to acne treatment, predominantly triggered by Propionibacterium acnes. This study aimed to determine the effect and proportion of carbopol 9... see more

The objective of this paper is to identify the area of investigation with the analysis of spatial, traffic, geotechnical, hydrological, ecological and climatic factors and constraints, and selection of optimum corridor by means of multi-criteria optimizat... see more

Vitamin C dalam bidang kosmetik memiliki banyak manfaat termasuk sebagai antioksidan. Akan tetapi sediaan vitamin C mudah teroksidasi dan mengalami perubahan warna sehingga perlu ditambahkan penstabil yang mampu menjaga kestabilan vitamin C selama pemakai... see more

Shielded Metal Arc Welding (SMAW), an arc welding process, is widely used in applications. In practice, SMAW is widely applied to the welding process on hollow square pipe. Performance expected from this welding is the tensile strength of weld joint. The ... see more

The aim of this paper is to investigate the possibility of drone optimization by selecting and testing the best material suitable for additive manufacturing technology and generative design approach, i. e. shape optimization. The use of additive manu... see more

The aerodynamic design philosophy and computational analysis of cross-country flight performance of Diana-2 sailplane in different thermal conditions are presented.  To address the second issue, a continuous spectrum of thermal models is created.&nbs... see more

In this paper, a design optimization algorithm is presented for non-linear steel frames with semi-rigid beamcolumnconnections using harmony search algorithm. The design algorithm obtains the minimum steel weight by selecting from a standard set of steel s... see more

Grain crops have been of great importance in providing food for man, feed for livestock and raw materials for some agro-based industries.  Studies in grain crops production in different parts of Nigeria have shown an increasing importance of the crop... see more
