Assessment of masonry arches and domes by simple models
The increase in the computational capabilities in the last decade has allowed numerical models to be widely used in the analysis, leading to a higher complexity in structural engineering. This is the reason why simple models are nowadays essential because they provide easy and accessible understanding of fundamental aspects of the structural response. Accordingly, this article aims at showing the ...

Looking Ahead to 200 and 400 Gb/s Networks
As 400 Gb/s switch options entered the market only recently, adoption has yet to take off. However, many expect 400 Gb/s to see real adoption in 2020. According to the Dell’Oro Group, a leading data center market analysis firm, 400 Gb/s shipments will most likely reach 15 million ports by ...

Analysis of Lead in Toys
Important and always current is the analysis of lead in toys for children. Details about the effective sample comminution with FRITSCH Mills. Lead is a toxic heavy metal. Approx. 90 % of the incorporated lead is deposited in the bones and the teeth. Because lead is released very slowly, it will be accumulated over the time in the body. This is dangerous especially for children. The European ...

Economic development through state ownership of oil and gas: evaluating Alaska's royalty-in-kind programme
Government owners of petroleum subsurface rights often face constituent pressure to exercise control over the disposition of these resources in pursuit of economic development objectives. At the same time, states cannot simply dissipate the potential rent from their resources without losing a principal revenue source. The paper takes a retrospective look at the state of Alaska's policies and ...

A bi-stable rolling hinge for variable geometry structures
A rolamite hinge is made up of two rollers held by three tensioned bands attached to either part, with ends of each band terminating on opposite sides of the hinge, ensuring a no-slip condition. This paper investigates the existence of alternative forms of the rolamite hinge by changing the profile of the rollers. The aim is to achieve a bi-stable rolling hinge that can be used to build a ...

Changing cultural clusters: a research note
This research note investigates the changes that occurred in cultural clusters between the studies of Hofstede in the 1970s and the GLOBE consortium in the 1990s, using similar measures and overlapping countries. Based on two leading methods for cluster analysis, we examined four common cultural dimensions: individualism, power distance, uncertainty avoidance and masculinity. The results suggest ...

Is sustainability a thermodynamic concept?
When calculating the 'degree of sustainability', socio-economic parameters and 'natural capital' are not easily quantified, and the question of the physical meaning of 'sustainability' in Thermodynamics remains relevant. On the basis of one single axiom: resource consumption of any kind can be quantified solely in terms of exergy flows, we demonstrate that for sufficiently complex systems certain ...

Global licensing strategies and technology pricing
Most manufacturing firms today realise that licensing is a powerful means to achieve their strategic goals. As an increasing number of industries experience globalisation, large as well as small firms are contemplating licensing in their wish to reach new markets or to reduce manufacturing costs. Among the numerous questions raised by licensing in the different fields of management, the ...

The fashion issue - an examination of the current intellectual property rights within England and Wales and the European community, concerning design infringement and counterfeit goods within the fashion industry: part two
The copying of fashion and graphic designs has been ongoing for years. More designers are beginning to assert their exclusive rights, granted through the available intellectual property rights. These mainly include design rights and trademarks. It is necessary to see how law of England and Wales can be applied effectively to protect this cyclical and transient industry, and the areas where it may ...

How sensitive is your treating plant to operating conditions?
Abstract Normal expectations in operating amine treating plants for acid gas removal is that small changes in operating conditions will result in correspondingly small responses in plant performance. However, such expectations are not always well founded. To establish credibility for the process simulator used in the design of a new LNG plant (ProTreat ), we begin by comparing its mass transfer ...

Economic instruments, transport and the global environment
The use of economic instruments, such as charges, in abating climate change is assessed, with special reference to their application in the transport sector. The general strategies and instruments for global environmental policies are presented. The role of economic instruments in this context is highlighted, both in terms of theory and of application. Economic instruments are then analysed from ...

The fashion issue – an examination of the current intellectual property rights within England and Wales and the European Community, concerning design infringement and counterfeit goods within the fashion industry: part one
The copying of fashion and graphic designs has been ongoing for years. More designers are beginning to assert their exclusive rights, granted through the available intellectual property rights. These mainly include design rights and trademarks. It is necessary to see how law of England and Wales can be applied effectively to protect this cyclical and transient industry, and the areas where it may ...

Chapter 4: three industrial revolutions
The management and prevention of technological risks and failures pose various industrial, political and theoretical challenges. This is due to the fact that the increasing complexity of technological systems invariably leads to increasing risk, especially when scientists and engineers are constantly pushing the limits of technological knowledge, harnessing vast forces of nature without full ...

A multinomial logit model of the factors influencing the adoption of environmental technologies in the pulp and paper sector in Spain
This paper provides an econometric analysis of the factors leading to environmental technology adoption in the pulp and paper industry in Spain. Three sets of interrelated factors influencing the widespread adoption of these technologies are considered: factors external to the firm, characteristics of the environmental technology and internal characteristics and conditions of the potential ...

Sequential extraction combined with isotopic analysis as a tool for studying lead contamination from mining activity
Tailings deposits generated from mining activities constitute a potential risk to the environment through leaching of potentially toxic elements hosted by a variety of minerals present in the mine-waste materials. In the present work, in an attempt to study the potential mobility of lead in different type of Pb-Zn ore concentrate residues and its environmental impact, a sequential extraction ...

An evaluation and comparison of the various statistical and deterministic techniques for forecasting the concentration of criteria air pollutants
A statistical approach is about working through the historical data in a general way and finding guides to future behaviour. In the present study, forecasting of the criteria pollutants has been done using simple statistical techniques and attempt has been made for an inter-comparison of these techniques with various advanced statistical and deterministic techniques. The inter-comparison analysis ...

A fuzzy approach for considering uncertainty in transient analysis of pipe networks
Uncertain parameters in the transient analysis of pipe networks lead to uncertain responses. Typical uncertainties are nodal demand, pipe friction coefficient and wave speed, which not only are imprecise in nature but also change significantly over time. Exploiting the fuzzy set theory and a simple scheme of the simulated annealing method, a conceptual model is developed. It can take into ...

Drivers for performance improvement originating from the Dutch drinking water benchmark
The Dutch drinking water sector has been benchmarked every 3 years since 1997, and the sector has significantly improved performance since then. Based on interviews with CEOs and financial managers of drinking water companies five drivers for improvement as a result of this benchmark are identified: ‘learning effect’, ‘enhanced transparency’, ‘managed competition’, ‘avoidance of negative ...
