We propose and demonstrate a new method for creation of fan-shaped optical vortex beams by rational phase modulation and assembly based on a well-known conical vortex phase.Our design is different from the previously proposed method for generation of power-exponential vortex beams.Such unconventional vortex Namco beams consist of multiple spiral be
This year, there are two ways to rectify buildings: forced landing and jacking up.The method of landing is to increase the settlement of the smaller side of the building, and the method of landing is the digging soil method, the irrigation method, the pile loading method, etc.the jacking method is on the basis of the stable foundation settlement, a
Besides the ingredient composition, another important thing in the process of making dough is proofing, ie.dough rising process prior to roasting process.Proofing process requires a stable temperature to ensure that the dough is well rising.The purpose of this research is to make a proofing machine that uses DHT11 as a temperature sensor.Proportion
Effective wildlife management is needed for conservation, economic and human well-being objectives.However, traditional population control methods are frequently ineffective, unpopular with stakeholders, may affect non-target species, and can be both expensive and impractical to implement.New methods which address these issues and offer effective w
