Van der Waals (vdW) interactions are prevalent in Nature and account for diverse natural phenomena, such as the flocculation of colloids and the adhesion of geckos to walls. Between similar dielectric materials such interactions are typically attractive and give rise to the problem of stiction and non-contact friction in micro and nano electro-mechanical systems, thus it is of importance to...
Rope fed uniformly from the height exhibits a perfectly circular coiling on a static plane. Introducing the rotation to the plane breaks the rotational symmetry of circle which gives rise to a variety of the more ordered patterns. For sufficiently fast feeding velocity $v$ the coiling shape laying on a rotating plane is a hypotrochoid, namely a closed curve with exterior loops, when plane...
We are interested in the generalization of the Proca field. In this work, we want to check that this system is a constrained system. Moreover, we want to check the number of degrees of freedom. We use the Faddeev-Jackiw method which is one of the techniques used for analyzing the constrained system. The result of this work shows that the system is a constrained system with 3 degrees of freedom.
Adaptive epidemic network is generally driven by two main processes: (1) infection-recovery process that changes the states of the nodes, and (2) rewiring process that modifies the topology of the network. We consider an adaptive susceptible-infected-susceptible (SIS) epidemic on a network. In this work, a link is rewired randomly to a chosen susceptible node according to a prescribed global...
A small fluctuation in velocities of the vehicles in a traffic system can cause a traffic jam which travels through the road as a stop-and-go wave. FollowerStopper controller is a strategy used in a self-driving car, designed for damping stop-and-go-wave. The previous study shows that controlling only one car can damp the wave in the whole circuit road. Interestingly, in some values of car...
We construct a quantum-mechanical model to explain the distribution of financial returns in a stock market. By combining a critical phenomenon effect in the form of a power law and the Schrodinger equation, we derive that an appropriate potential of the financial returns is given by a time-dependent inverted anharmonic oscillator, whose coefficients depend on the critical time and critical...
Considering equilibrium thermodynamics- the thermostatics,foundation of the paradigms are the equation of state (EoS) and four postulate laws of thermodynamics. We investigate nature of EoS and these laws and we propose a paradigm in analogous to thermostatics in expressing EoS for a microeconomics system that is a market. This speculation is a first step to the whole and overall pictures of...
