This paper presents a linkage factors synthesis and multi-level optimization technique for bi-stable compliant mechanism. The linkage synthesis problem is modeled as multiple level factors and responses optimization problem with constraints. The bi-stable compliant mechanism is modeled as a crank slider mechanism using pseudo-rigid-body model (PRBM). The model exerts the large deflection of fle...

Background: Recent researches have provided evidences of the importance of endothelin axis in carcinogenesis. According to our knowledge, no data exists about endothelin A receptor (ETA) expression in dysplastic oral mucosa (DOM). Therefore, the aim of the present study was to evaluate immunohistochemical expression of ETA in DOM. Methods:</strong...

The possibility of the production ‘ogi’ (a Nigerian cereal-porridge) with optimum quality was investigated using Response Surface Methodology (RSM). Grains white maize (Zea mays) and sorghum (Sorghum bicolor) were used separately in combination (1:1 w/w), as substrates for fermentations a duration 48h at ambient conditions. starter cultures controlled experiment consisted 2 strains Lactobacillu...

This study is aimed at the optimization of calcined termite mound material incorporated in mortar and concrete using Response Surfaces Methodology (RSM). The substituting cement varied from 5 to 15% interval 5% concrete. Sikament NN was added 1.0 3.0 1.0. Test conducted on were: consistency setting times. For concrete, specimens were cast tested failure for all mixes curing periods 3, 7, 28, 60...

The Web is the largest information repository. The information it contains is usually available in human-friendly formats. Companies are interested in using this information. The problem is that they need it in structured formats so that they can use it in automated business processes. In the literature, there are many proposals to infer information extractors. They build on machine learning te...

Ultrasonic vibration assisted single point incremental forming (UVaSPIF) is based on localized plastic deformation in a sheet metal blank. It consists to deform gradually and locally the sheet metal using vibrating hemispherical-head tool controlled by a CNC milling machine. The ultrasonic excitation of forming tool reduces the vertical component of forming force. In addition, application of ul...
