This is a qualitative research study which investigates the curriculum decision-making of four primary school history subject-leaders in North-West England. A grounded theory approach was utilised. Semi-structured interviews were conducted with and an audit their schools’ completed. The altered response to Colston statue toppling three schools, faced several challenges. Further needed discover ...

In the wake of riotous procession that toppled statue Edward Colston, this essay sketches an ethnographic itinerary through spectral geographies Bristol, a circum-Atlantic city haunted by ghosts slavery. The paper offers Caribbean cosmological reading toppling and aqueous burial as kind duppy conquering, vital act social renewal clears ground for processes spiritual affective repair. then explo...

Avalanche dynamics is an indispensable feature of complex systems. Here, we study the self-organized critical dynamics of avalanches on scale-free networks with degree exponent through the Bak–Tang–Wiesenfeld (BTW) sandpile model. The threshold height of a node i is set as k1− i with 06 ¡ 1, where ki is the degree of node i. Using the branching process approach, we obtain the avalanche size and...

In this article, we propose a mechanical rubbing method to eliminate the optical bounce and decrease the response time of homeotropic liquid crystal (LC) cells with sputtered silicon dioxide alignment films. After gently rubbing the inorganic alignment film (sputtered silicon oxide, SiO2), the decreasing polar anchoring energy results in slightly smaller pretilt angle which gives LC a toppling ...

We show that Zhang’s sandpile model (N , [a, b]) on N sites and with uniform additions on [a, b] has a unique stationary measure for all 0 ≤ a < b ≤ 1. This generalizes earlier results of [6] where this was shown in some special cases. We define the infinite volume Zhang’s sandpile model in dimension d ≥ 1, in which topplings occur according to a Markov toppling process, and we study the stabil...

In the Abelian sandpile models introduced by Dhar, long-time behavior is determined by an invariant measure supported uniformly on a set of implicitly defined recurrent configurations of the system. Dhar proposed a simple procedure, the burning algorithm, as a possible test of whether a configuration is recurrent, and later with Majumdar verified the correctness of this test when the toppling r...

We study stochastic sandpile models with a height restriction in one and two dimensions. A site can topple if it has a height of two, as in Manna's model, but, in contrast to previously studied sandpiles, here the height (or number of particles per site), cannot exceed two. This yields a considerable simplification over the unrestricted case, in which the number of states per site is unbounded....

— The initial resting pose of many industrial parts differs from the orientation desired for assembly. We show that it is possible to align parts during grasping using a standard parallel-jaw gripper. A solution is an arrangement of four gripper point contacts that will align the part in the vertical plane as the jaws close. Given a n-sided polygonal part and k uniformly distributed sample poin...

We numerically study avalanches in the two-dimensional Abelian sandpile model in terms of a sequence of waves of toppling events. Priezzhev et al. @Phys. Rev. Lett. 76, 2093 ~1996!# have recently proposed exact results for the critical exponents in this model based on the existence of a proposed scaling relation for the difference in sizes of subsequent waves, Ds5sk2sk11 , where the size of the...

We show that the one-dimensional Oslo rice-pile model is a special case of the abelian distributed processors model. The exact steady state of the model is determined. We show that the time evolution operator W for the system satisfies the equation Wn+1 = Wn where n = L(L + 1)/2 for a pile with L sites. This is used to prove that W has only one eigenvalue 1 corresponding to the steady state, an...
