This article intends to demonstrate synchronous in-process control of both external size and internal structure of ball processed particulates by regulation of the power cycle. For this reason, a coupled, nonlinear, computational model of the cycle elements is laid out, modeling joint and crack occurrences influencing the structure of particulates, along plastic distortion of spatial domains in their microstructure. The physics-based structural simulation emphasizes probabilistic representations of impactor collisions, particle assembly and population growth; While a simpler stochastic model of external particle features is based on statistical formulations of impact energetics, friction and plastic deformation effects, as well as bonding and fracture transformations of the particles during the process. 

The structural simulation reactions are calibrated and validated against the predictions of the stochastic model, as well as specially designed experiment data. Their real-time monitoring ability allows planning and control of the power cycle, utilizing substitute feedback from the predictions of the model, under a self-tuning regulation controller. This control scheme is tentatively implemented in low-energy planetary ball processing of Al and Ni powders for manufacturing of ignitable reactive bimetallic particulates, and the particle morphology and structureare found in concurrence with electron micrograph observations.

Promoting the transition from the current linear production and consumption model to a green model has become a central issue in the debates on global warming and climate change [1] [2]. The way we design and produce our products directly affects the types and intensities of impacts generated on the environment and, consequently, on the planet [3]. However, with the aim of deliberately creating products with a shorter lifespan than they could have and making consumers purchase new products in short intervals of time, obsolescence has been used by industries as a tool to increase consumption. [ 4]. This problem is particularly noticeable in the smartphone production model. This article intends to carry out a qualitative and quantitative analysis of the current production and consumption model, proposing an analysis of the factors that influence the increase in smartphone consumption, highlighting both the motivating factors and the hindering factors, also intending to identify how such practices can violate several Brazilian laws [5]. To achieve this, research developed a questionnaire via Google Forms, applied to 186 people. The results show that external motivators (such as marketing incentives and social stimuli), internal motivators (self-actualization), external impediments (economic barriers) and internal impediments (barriers of mental awareness and perception of real need) were the four determining factors that influenced or prevented new consumption.
