Experimental Study of Upsetting and Die Forging with Controlled Impact
The results from experimental research of deformation by upsetting and die forging of lead specimens wit controlled impact are presented. Laboratory setup for conducting the investigations, which uses cold rocket engine operated with compressed air, is described. The results show that when using controlled impact is achieving greater plastic deformation and consumes less impact energy than at ordinary impact deformation process. Keywords—Rocket Engine, Forging Hammer, Sticking Impact, Plastic Deformation.
InterCriteria Decision Making Approach for Metal Chips Briquetting
In the presented paper for the analysis purposes we have used experimental results of impact briquetting of grey cast iron chips. The presented multicriteria decision making method is based on two fundamental concepts: intuitionistic fuzzy sets and index matrices. We have named it ‘InterCriteria’ decision making approach, which utilizes the apparatus of index matrices and intuitionistic fuzzy sets takes an existing multiobject multicriteria evaluation table and generates a new table that contains estimations of the pairwise relations among the set of evaluating criteria. Our goal is to increase the efficiency of the process of briquetting metal chips with good density and quality.
REJOINDER TO BLOCK'S DEFENSE OF EVICTIONISM
I AM THANKFUL TO WALTER BLOCK (2010) for his comprehensive and perspicacious engagement with my critical remarks regarding his theory of evictionism (Wisniewski 2010). I also appreciate his kind words about what he sees as the merits and strong points of my argumentation. However, as one could easily surmise from my decision to write this rejoinder, I found his defense of evictionism unconvincing, though certainly informative and thought-provoking. Without further ado, let me now proceed to explaining why.
