The paper describes a dynamical economic model with discrete time and consumer sentiment in the deterministic and stochastic chicago cubs earrings cases.We seek to demonstrate that consumer sentiment may create fluctuations in the economical activities.The model possesses a flip bifurcation and a Neimark-Sacker bifurcation, after which the stable s
Engineering Design, Kinematic and Dynamic Analysis of High Lugs Rigid Driving Wheel, a Traction Device for Conventional Agricultural Wheeled Tractors
Traction failure on loose terrain is common in conventional agricultural wheeled tractors due to poor traction ability and lower power transfer efficiency of drive wheels, which leads to excessive energy consumption and soil compaction in agriculture.To overcome the problem, this paper presents a new design of a rigid lugged wheel for use in field
Behavior of High Strength Reinforced Cement Concrete with Polypropylene and Steel Fibres
The robustness, hardness, and longevity of high strength conventional concrete have long been sought after qualities.Fibre reinforced concrete (FRC) was created to address shortcomings.The purpose of fibres used is to control cracking and to enhance tensile strength, flexural strength, toughness, impact strength, and failure mode by enhancing post-
On the research of cultural relic restoration under reverse design
At present, artificial restoration of cultural relics has been unable to solve the difficulties in restoration and protection of cultural relics, as well as low restoration rate a series of click here problems.In order to solve the above problems, this article conducts in-depth research on the emerging computer technology that can be used for cultu
