In this study, a logistic regression model is applied to credit scoring data from given Portuguese financial institution evaluate the default risk of consumer loans. It was found that increases with loan spread, term and age customer, but decreases if customer owns more cards. Clients receiving salary in same banking have less chances than clients their another institution. We also lowest income tax echelon propensity default. The predicted correctly 89.79% cases.
As robots are starting to become part of our daily lives, they must be able cooperate in a natural and efficient manner with humans socially accepted. Human-like morphology motion often considered key features for intuitive human–robot interactions because allow human peers easily predict the final intention robotic movement. Here, we present novel planning algorithm, Upper-limb Motion Planner, upper limb anthropomorphic robots, that generates collision-free trajectories human-like...
The growing globalization of the different types market requires that companies invest, in a recurrent way, to optimize and improve all processes inherent their activities. Aluminium extrusion is main industrial process used create profiles fixed cross-section. This appropriate processing parameters be used, order produce diverse high-quality products. company's ability adapt productive are differentiating factors against competition. Thus, understand operations dynamics crucial. work...
In real manufacturing environments, scheduling can be defined as the problem of effectively and efficiently assigning tasks to specific resources. Metaheuristics are often used obtain near-optimal solutions in an efficient way. The parameter tuning metaheuristics allows flexibility leads robust results, but requires careful specifications. a priori definition values is complex, depending on instances This paper implements novel approach automatic specification metaheuristic parameters, for...
The challenge proposed by ara Shoes Portugal was to improve the efficiency of a shoe injection machine, using as main indicator Overall Equipment Effectiveness (OEE). To do that, focus on planning machine minimise cycle losses while maximising production different articles. This could be identified Scheduling Problem (SP), well-known class NP-hard problems. tackle ara's challenge, novel mathematical model developed that addressed characteristics and current practices company's shop floor....
Humans are experts in cooperating a smooth and proactive manner. Action intention understanding critical components of efficient joint action. In the context EU Integrated Project JAST [16] we have developed an anthropomorphic robot endowed with these cognitive capacities. This project respective (ARoS) is focus video. More specifically, results illustrate crucial capacities for successful human-robot collaboration such as goal inference, error detection anticipatory action selection....
A new approach to study the compatibilization effect of organophilic clays in PA6/PP polymer blends through experimental results tests is presented. This focuses on description interphase by addition organoclays into blend melt compounding using a Twin Screw Extruder. The variations, uncompatibilized and compatibilized blend, are studied parametric non-parametric analysis variance. For all results, significant differences between were identified.
In previous work we have presented a model capable of generating human-like movements for dual arm-hand robot involved in human-robot cooperative tasks. However, the focus was on generation reach-to-grasp and reach-to-regrasp bimanual no synchrony timing taken into account. this paper extend order to accomplish manipulation tasks by synchronously moving both arms hands an anthropomorphic robotic system. Specifically, new extended has been designed two different with degrees difficulty....
Entrepreneurship is a theme of global interest, and it the subject investigations conducted by many researchers projects. In particular, Global Monitor project that involves several countries years surveys on entrepreneurship indicators. This study focuses 12 indicators entrepreneurial ecosystem defined Entrepreneurial Framework Conditions (EFCs). The EFCs are specifically related to quality ecosystem. Using clustering techniques, present analyzes how European experts’ perceptions their home...
Global Entrepreneurship Monitor is a large scale database for internationally comparative entrepreneurship that includes information about many aspects of activities, perceptions, conditions, national and regional policy, among others, number countries. This project has two main sources primary data: the Adult Population Survey National Expert Survey. In this work 2011 2012 datasets are studied. Our goal to analyze effects different type expert specialization on perceptions Entrepreneurial...
This study investigates the scheduling of mechanical repairs performed at a Portuguese firm in automobile sector. The aim is to reduce amount time that vehicles spend inactive between interventions by developing mathematical model takes into account available resources and mechanics, necessary interventions, required for each repair. To accomplish this, mixed-integer linear programming (MILP) was employed, incorporating various variables schedule allocate resources, determine start times...
Human‐like movement is fundamental for natural human‐robot interaction and collaboration. We have developed in a model generating arm hand movements an anthropomorphic robot. This was inspired by the Posture‐Based Motion‐Planning Model of human reaching grasping movements. In this paper we present some changes to proposed [4] test compare different nonlinear constrained optimization techniques solving large‐scale problem that rises from discretization our time‐continuous model. Furthermore,...
Abstract This paper addresses a case study regarding inventory models for acquiring liquefied petroleum gas (LPG) cylinders. is an industrial challenge that was proposed at European Study Group with Industry, by Portuguese energy company, which the LPG cylinder main asset of its business. Due to importance this asset, acquisition plan must be defined in order determine amount cylinders acquire, and when acquire them, optimize investment. As are returned refilled, reverse logistic flows these...

The effect of processing conditions material and interfacial/ interphase properties in clay/polymer nanocomposites are usually studied through experimental results X-ray diffraction, transmission electron microscopy rheology mechanical tests. In this paper, the interaction parameters measure by employing multivariate analysis variance technique. This model is used to establish relations between several interfacial/interphase characteristics with conditions. These then analyzed detail, using...
