Localization in musical steelpans

The steelpan is a pitched percussion instrument that takes the form of a concave bowl with several localized dimpled regions of varying curvature. Each of these localized zones, called notes, can vibrate independently when struck, and produces a sustained tone of a well-defined pitch. While the association of the localized zones with individual notes has long been known and exploited, the relationship between the shell geometry and the strength of the mode confinement remains unclear. Here, we explore the spectral properties of the steelpan modeled as a vibrating elastic shell. To characterize the resulting eigenvalue problem, we generalize a recently developed theory of localization landscapes for scalar elliptic operators to the vector-valued case, and predict the location of confined eigenmodes by solving a Poisson problem. A finite element discretization of the shell shows that the localization strength is determined by the difference in curvature between the note and the surrounding bowl. In addition to providing an explanation for how a steelpan operates as a two-dimensional xylophone, our study provides a geometric principle for designing localized modes in elastic shells.Comment: 17 pages, 5 figure

A field-level examination of the adoption of sustainable procurement in the social housing sector

Purpose – The purpose of this paper is to report on a field-level examination of the adoption of sustainable procurement in social housing. It explores the role of regulation and procurement consortia in sustainable procurement. Design/methodology/approach – The study employs a case study of the UK social housing sector and uses an online survey (n=116) of UK Housing Associations. Factor analysis identifies three parsimonious dimensions of sustainable procurement. Attitudinal data are analysed to explore the field-level adoption of sustainable procurement and the role of consortia. Findings – The results delineate sustainable procurement activities into three factors; direction setting, supplier-centric assurance and local socially oriented supply. High yet sup-optimal levels of sustainable procurement activity are revealed. Prevailing attitudes identify positive commitments to sustainable procurement at individual, organisational and sector levels. The value of network collaboration is identified. Tenants as critical stakeholders do not prioritise sustainable procurement creating challenge for inclusivity. Regulators are seen to a have low level of sustainable procurement knowledge and procurement consortia a high perceived knowledge. Research limitations/implications – Results provide insight into the effect of sustainable procurement policy, the role of regulators and network structures and consortia, raising issues around legitimacy, coopetition, stakeholder engagement, performance measurement, and functional/sectoral maturity. Social implications – The identification of the potential exclusion of tenants in sustainability debates is particularly significant to deliver social value. Originality/value – The relative newness of the social housing sector and its quasi-public sector status provides an original contribution to the consortia and sustainable procurement literatures

Measuring Performance to Engage the Extended Project Team in Construction

In construction, stakeholders of extended project team play a key role in the overall project performance. Successful integration of stakeholders demands for good management practices at strategic, operational and project levels. Targets and measures to improve the stakeholder performance encourage the creativity and willingness of stakeholders of extended project team to develop the better ways to achieve the project objectives. This paper presents a generic descriptive method, showing how stakeholder's ability and influence impacts on project performance in the construction sector. The findings of a series of interviews with key informants are presented and the following main conclusion is drawn: improving project performance through stakeholder's contribution and measuring their performance can strengthen the project performance. This innovative approach which redefines the process of improving the project performance in construction projects will be of interest to those who intend to manage the projects in practice as well as to those who interested in advancing theory

Resolving agency issues in client-contractor relationships to deliver project success

In our research we seek to explain why some relationships between project client and contractors are managed in such a way that leads to success and others are not. In doing so, we analyze how the relational risk that exists when a client sources a project from an external organization is managed. We view the topic through a lens of agency theory and we use a multiple case study research design, analyzing projects from the construction and clinical research business sectors that had varying degrees of success. We extend knowledge of managing relational risk by developing a framework for resolving agency-related issues to deliver project success. The framework encompasses mechanisms to managing relational risk which we classify in five broad areas: contract, understanding, resources, education and delegation – the CURED framework. These areas reflect both formal and informal mechanisms as described in existing literature

Optimal strategies for kiiking: active pumping to invert a swing

Kiiking is an extreme sport in which athletes alternate between standing and squatting to pump a standing swing till it is inverted and completes a rotation. A minimal model of the sport may be cast in terms of the control of an actively driven pendulum of varying length to determine optimal strategies. We show that an optimal control perspective, subject to known biological constraints, yields time-optimal control strategy similar to a greedy algorithm that aims to maximize the potential energy gain at the end of every cycle. A reinforcement learning algorithms with a simple reward is consistent with the optimal control strategy. When accounting for air drag, our theoretical framework is quantitatively consistent with experimental observations while pointing to the ultimate limits of kiiking performance

Introducing AgiLean to Construction Project Management

The complexity of construction projects is the main reason, why the construction industry is searching better ways of managing construction projects. Recently, the industry tries to get benefit from the adoption of two management methodologies. On the one hand there is Lean construction, which works well for stable and predictable project environments. On the other hand, there is Agile project management [PM], which works well for dynamic and uncertain project environments. Construction projects, however, are exposed to predictable and paradoxically uncertain environments at the same time. Hence there is a need for a methodology which merges Lean and Agile to a holistic unit. The objective of this contribution is to introduce such a methodology. Such a methodology does not exist so far and is different from the “Leagile” approach, which uses Lean and Agile methods in the execution phase sequentially. Through undertaking a comprehensive literature review and through conducting 22 interviews with practitioners in the field of construction PM, Lean, Agile a new methodology is introduced, which is conceptualised as “AgiLean PM”.
