Bazaar economics
2015
Competitive Equilibrium theory has been a widely accepted and extensively used cornerstone in economics for over a century. Here, we suggest a complementary model—motivated by the haggling in a bazaar—that offers a useful, first-principle account of market behavior that better accounts for the observed outcomes in forty market experiments. The Bazaar model uses simple stochastic processes to drive the matching of traders and the determination of price. We show that as agents become more impatient, the system tends toward more Competitive-Equilibrium-like outcomes.
A New Approach to Evaluate the Biomechanical Characteristics of Osseointegrated Dental Implants
2019
Tooth loss is a common pathology that affects many people. Dental osseointegrated implants are the ideal solution to restore normal functionality in partially or completely edentulous patients. The not perfect osseointegration and the fixture fracture are the main causes of failure for these kinds of implant. To avoid these drawbacks, several studies have been conducted to analyse the behaviour of dental implants. Aim of this work is to analyse the biomechanical behaviour of three different endosseous dental implants. For this purpose, a new numerical model has been developed to simulate different levels of osseointegration and to evaluate the stress values on the bone at different times. I…
Influence of Vertical Dimension of Occlusion on Peak Force During Handgrip Tests in Athletes
2018
Background: In contact sports, such as martial arts, protection from oral injuries is generally recommended. Several authors have focused on the effects of wearing such oral protective gear on sports performances and, in particular, occlusal devices. Although many studies have shown improvements in athletic performance, especially in maximal isometric strength, to date there is still no consensus on the issue. Objectives: The aim of our study was to evaluate differences in isometric handgrip before and after the application of an occlusal splint (OS) in martial arts athletes. Methods: A repeated measures within-subjects design was adopted for the study. Twenty-five young martial arts athlet…
Picco di massa ossea ed attività fisica: confronto tra giovani adulti sedentari, attivi e atleti
2009
OBIETTIVO - Valutare, nel periodo di raggiungimento del picco di massa ossea, gli effetti dell’attività fisica sulla mineralizzazione ossea in età giovanile. MATERIALI E METODI - Allo studio hanno partecipato 43 soggetti maschi, sani, con età media di 25 anni, suddivisi in tre gruppi in relazione all’intensità dell’attività fisica svolta dall’età di dieci anni in poi: il primo composto da 17 soggetti sedentari, il secondo da 16 soggetti attivi e il terzo da 15 soggetti atleti. Ogni soggetto è stato sottoposto a mineralometria ossea computerizzata (DEXA). La misurazione della densità ossea (BMD, g/cm2) dei soggetti ha riguardato: corpo intero (Total Body), collo femore dx e sx e tratto rachi…

A parallel simulated annealing approach to the K shortest loopless paths problem
1997
The k shortest loopless paths problem is a significant combinatorial problem which arises in many contexts. When the size of the networks is very large the exact algorithms fail to find the best solution in a reasonable time. The aim of this paper is to suggest parallel efficient algorithms to obtain a good approximation of the solution to the k shortest loopless paths problem between two arbitrary nodes, when the network size is large. The heuristic used is known in literature as Simulated Annealing. Preliminary tests have been conducted for evaluating the validity of the proposed algorithms. The quality of the obtained results represents a significant base for further experimentations.
The combined distribution/assignment problem in transportation network planning: a parallel approach on hypercube architecture
1995
The joint distribution/assignment problem plays a central role in urban transport network planning. In this problem, according to the mathematical model proposed by S. P. Evans, the trips are iteratively calculated and assigned to the network in such a way that the resulting traffic flows pattern satisfies the selfish equilibrium condition. Unfortunately the number of variables and constraints increase hardly with the greatness of the networks causing long computational time for the equilibrium solution. In this paper an nCUBE 2 parallel computing architecture is employed to solve the combined problem and to asses the potential of MIMD machines to handle large scale transportation network p…
