In view of the problem of centrifugal pump impeller wear, the existing research mostly concentrates on numerical simulation analysis, vibration signal analysis and wear detection of impeller wear.There are few studies on the working condition parameters of centrifugal pump under impeller wear.In order to solve this problem, a health condition asses
This paper deals with a new control strategy for the programmable dynamometer to emulate dynamic loads.The main idea Top Load Washer is to employ the disturbance-observer-based design and take the nominal model involved in the disturbance-observer design as the desired dynamics to be emulated.Compared to previous approaches, the proposed approach d
Pepper is one of the most important vegetable in the sub-sahara Africa, however, production is still limited by low soil vibrating-cockrings fertility.Hence, the objective of this paper was to assess the effect of poultry manure rates on growth and yield of three Capsicum spp pepper (green pepper, nsukka yellow pepper, red bell pepper) species in A
Forests dominate carbon (C) exchanges between the terrestrial biosphere and the atmosphere on land.In the long term, the net carbon flux between forests Toaster and Kettle Sets and the atmosphere has been significantly impacted by changes in forest cover area and structure due to ecological disturbances and management activities.Current empirical a
The modernization of technologies has led to the escalation of the demand for silver in the electrical and electronics manufacturing sectors.Conventional lean grade ores of silver are insufficient to account for silver Furniture consumption.This deficit compels the extraction engineers to broaden the scope and delve into secondary silver recovery a
