Attitudinal Choquet integral (ACI) is a recent aggregation operator thatconsiders in the aggregation process the criteria interaction and the DM's attitude, both of which arespecific to the decision-maker. However, this capability comes at the cost of increasedcomplexity that hinders its applicability in big data analytics.To address the same, in this paper, we explore some heuristics-based forms of the ACI operator, so as to somehow overcome its complexity.We devise new and efficient forms of $\mathcal{ACI}$, and test their validityin the real world datasets, against the backdrop of preference learning.

If the bodies, such as the head and nose of missile, nozzle or combustion chamber of the rocket, which are exposed to sever heat, are not protected against it, then they cannot perform for the purpose they are designed. One of the recommended methods to protect these systems against heat is the usage of the ablative insulators. In this work, the thermal behavior of ablative composites of silicon rubber matrix and glass reinforced fibers was studied and modelled. For this purpose, the mass and energy equation in ablation conditions were simultaneously solved numerically using finite difference method and the various related parameters of the insulator were determined as a function of temperature and time. This modelling will allow to predict the proper thickness of the ablative composite in the actual service conditions. This method can also be used in designing of the other ablative composites.

How to profoundly change the beliefs of the polytheists during the age of revelation from the denial of the Prophet (pbuh) to the certainty of his Message and the acceptance of his full guardianship is a question worthy of attention. The order of verses about prophecy based on the order of revelation is the reason to lead a transformative process and a special Quranic method in institutionalizing the belief of prophecy in the lives of Arabs. In the first stage, the Holy Quran in the first Makkī (Arabic: المکّیّ, suras revealed in Mecca) chapters has prepared the community from the motivational side to accept the truth of the Prophet’s (pbuh) prophecy and briefly stating the key issues surrounding it. The Holy Book of Quran at the time of the emergence of oppositions and doubts (the second stage) destroyed the arguments of the polytheists and explained the prophecy and proved its authenticity from a cognitive perspective in the second stage by presenting clear arguments. and the Holy Book of Quran in the third stage after Madanī (Arabic: المدنیّ, suras revealed in Medina) period has undertaken measures in order to fulfill the goals of the Massage by explaining the true position of the Prophet (pbuh) to deepen and operationalize the Prophetic belief through explaining practical duties for the Prophet (pbuh) and behavior based on the acceptance of Walaya (Arabic: ولایة, meaning “guardianship” or “governance”).

An approach for modeling of cutting force in ball-end milling process is presented in this paper. This model has the capability of estimating the cutting forces for various cutting conditions. A commercially available geometric engine (ACIS) is used to represent the cutting edge, cutter and updated part. (To determine cutting edge engagement for each tool rotational step, the intersections between the cutting edge and boundary of the contact face, and between tool and updated part, are determined). The engaged portion of the cutting edge is divided into small differential oblique cutting edge segments and the cutting force components are calculated by summing up the differential cutting forces, A series of experiments were performed to verify the proposed approach.

The objective of this paper is to investigate, in a simplified manner, the process of rock blasting in discontinuous and blocky rock media. The developed code considers the effects of blast geometry (blasthole shape, angle, and location), the physical properties of the intact rock and existing discontinuities, and the blasthole pressure on the processes of rock breakage, fragment throw and muckpile formation. The newly modified DDA code (DDA_BLAST) describes the expansion of the blast chamber as a function of blast chamber volume and time. It is assumed in the code that the media consists of a blocky rock mass which is already fragmented in-situ due to the intersection of pre-existing discontinuities and the passage of stress wave. Hence, the model only considers the gas pressurization phase of the blasting process. Moreover, the proposed model for blasthole expansion assumes an adiabatic expansion of explosion products and variations in explosion pressure upon expansion of blast chamber is calculated from an equation of state. The newly developed DDA_BLAST code was employed to simulate a typical bench blasting problem in jointed rock mass and delve into the mechanisms involved (in a macro scale) in the gas pressurization phase of the blasting process.
