Vibration control strategy for large-scale structures with incomplete multi-actuator system and neighbouring state information

2016

The synthesis of optimal controllers for vibrational protection of large-scale structures with multiple actuation devices and partial state information is a challenging problem. In this study, the authors present a design strategy that allows computing this kind of controllers by using standard linear matrix inequality optimisation tools. To illustrate the main elements of the new approach, a five-story structure equipped with two interstory actuation devices and subjected to a seismic disturbance is considered. For this control setup, three different controllers are designed: an ideal state-feedback H 8 controller with full access to the complete state information and two static output-fee…

A Review of Recent Range Image Registration Methods with Accuracy Evaluation

2007

International audience; The three-dimensional reconstruction of real objects is an important topic in computer vision. Most of the acquisition systems are limited to reconstruct a partial view of the object obtaining in blind areas and occlusions, while in most applications a full reconstruction is required. Many authors have proposed techniques to fuse 3D surfaces by determining the motion between the different views. The first problem is related to obtaining a rough registration when such motion is not available. The second one is focused on obtaining a fine registration from an initial approximation. In this paper, a survey of the most common techniques is presented. Furthermore, a sampl…

The magnitude of a product recall: offshore outsourcing vs. captive offshoring effects

2018

The escalation in product recalls in recent years is attributed to the rise of globalisation and associated challenges of offshoring. Extant SCM research suggests that product recalls have a significant negative impact on financial performance, but gaps exist relative to the managerial actions to minimise their impact. Recall response strategies have become more important in the press, given that a single recall may result in the mandatory withdrawal of millions of products from the market, with firms incurring enormous logistics costs and brand damage. In this study, we address this gap in the research, and using a measure of product recall defined as the volume of products withdrawn from …

Opinion dynamics in social networks through mean field games

2016

Emulation, mimicry, and herding behaviors are phenomena that are observed when multiple social groups interact. To study such phenomena, we consider in this paper a large population of homogeneous social networks. Each such network is characterized by a vector state, a vector-valued controlled input, and a vector-valued exogenous disturbance. The controlled input of each network aims to align its state to the mean distribution of other networks' states in spite of the actions of the disturbance. One of the contributions of this paper is a detailed analysis of the resulting mean-field game for the cases of both polytopic and $mathcal L_2$ bounds on controls and disturbances. A second contrib…

Lying Cheating Robots : Robots and Infidelity

2018

Love has been described as unpredictable, immeasurable and non-purchasable and as such, poses challenges for anyone in a relationship to both stay in love, and to not fall in love with someone else. Scientists are still discovering whether or not love follows any specific recipe. Outlooks, personality, sense of humor and talent may not perfectly guarantee an individual falls in love with another, and more importantly is able to sustain that relationship. This article portrays a futuristic scenario in which truly intelligent and emotional robots already exist. Here, the bi-directional love discussed in Lovotics is not simulated through engineering, but rather is genuine from the perspectives…

Aesthetic considerations for the min-max K-Windy Rural Postman Problem

2017

[EN] The aesthetic quality of routes is a feature of route planning that is of practical importance, but receives relatively little attention in the literature. Several practitioners have pointed out that the visual appeal of a proposed set of routes can have a strong influence on the willingness of a client to accept or reject a specific routing plan. While some work has analyzed algorithmic performance relative to traditional min-sum or min-max objective functions and aesthetic objective functions, we are not aware of any work that has considered a multi-objective approach. This work considers a multi-objective variant of the Min-Max K-Vehicles Windy Rural Postman Problem, discusses sever…

The Impact of Regionalism on Democracy Building: An Examination of the Southern African Development Community (SADC)

2017

Since the early 1990s, the world has witnessed a new wave of regionalism and a mushrooming of regional integration organizations, particularly in the global South. Focusing on Africa, the Southern African Development Community (SADC) ranks among the most promising examples of regionalism on the continent. The SADC explicitly aims at building and advancing democracy in the region and its member states as part of its broader agenda on regional development. From a political science perspective, there is general agreement that regional integration and parallel institution building can be useful measures to promote and strengthen democratic rule, since an appropriate institutional “lock-in” impl…

Economic globalisation, the perceived room to manoeuvre of national governments, and electoral participation: Evidence from the 2001 British General …

2016

Recent macro-level research argues that economic globalisation negatively affects electoral turnout by constraining the leeway of national governments and thereby rendering elections less meaningful to voters. This article analyses the link between perceptions of the national government's room to manoeuvre and turnout on the individual level. Drawing on the 2001 British General Election, it is shown that citizens who believe that economic globalisation leaves the national government with less influence on the economy are less likely to report to have voted. Further findings also support the proposed theoretical model according to which room to manoeuvre perceptions affect turnout via views …

Decreases in aerobic fitness during military operations have been observed in several studies. Thus, differences in training adaptations during a 6-month crisis-management operation were compared by using the change in endurance performance as the outcome measure. Sixty-six male soldiers volunteered for the study, consisting of pre–post assessments of blood biomarkers, body composition, physical performance, and the military simulation test (MST) performance. Physical training volume was self-reported. After the follow-up, the data were divided based on individual changes in endurance performance. Endurance performance was improved in the high-responder group (HiR, n = 25) and maintained or…

Introduction: Research Interest and Research Questions

2017

This chapter explores the theoretical and empirical puzzles of regionalism in the Global South on the example of the Southern African Development Community (SADC). The SADC is one of the most realistic and promising examples of the new regionalism and shows constant dynamics in a number of policy areas. The main research interest of this much-needed analysis is to explain the emergence, institutional design and performance of regionalism in the SADC from a political science perspective. In order to provide innovative research, the analytical focus is on the role and influence of regional key countries and, particularly, external actors. Moreover, this chapter offers a comprehensive overview…
