New Approach Directives now govern the health and safety of most products whether destined for workplace or domestic use. These Directives have been enacted into UK law by various specific legislation principally relating to work equipment, machinery and consumer products. This research investigates whether the risk assessment approach used to ensure the safety of machinery may be applied to consumer products. Crucially, consumer products are subject to the Consumer Protection Act (CPA) 1987, where there is no direct reference to 'assessing risk'. This contrasts with the law governing the safety of products used in the workplace, where risk assessment underpins the approach. New Approach Directives are supported by European harmonised standards, and in the case of machinery, further supported by the risk assessment standard, EN 1050. The system regulating consumer product safety is discussed, its key elements identified and a graphical model produced. This model incorporates such matters as conformity assessment, the system of regulation, near miss and accident reporting. A key finding of the research is that New Approach Directives have a common feature of specifying essential performance requirements that provide a hazard prompt-list that can form the basis for a risk assessment (the hazard identification stage). Drawing upon 272 prosecution cases, and with thirty examples examined in detail, this research provides evidence that despite the high degree of regulation, unsafe consumer products still find their way onto the market. The research presents a number of risk assessment tools to help Trading Standards Officers (TSOs) prioritise their work at the initial inspection stage when dealing with subsequent enforcement action.

The primary aim of the thesis is to provide a comprehensive investigation of the osmotic dehydration processes in plant tissue. Effort has been concentrated on the modelling for simulating the processes. Two mathematical models for simulating the mass transfer during osmotic dehydration processes in plant tissues are developed and verified using existing experimental data. Both models are based on the mechanism of diffusion and convection of any mobile material that can transport in plant tissues. The mass balance equation for the transport of each constituent is established separately for intracellular and extra-cellular volumes with taking into account the mass transfer across the cell membrane the intracellular and extra-cellular volumes and the shrinkage of the whole tissue. The contribution from turgor pressure is considered in both models. Model two uses Darcy’s law to build the relation between shrinkage velocity and hydrostatic pressure in each volume because the plant tissue can be considered as the porous medium. Moreover, it has been extended to solve the multi-dimensional problems. A lot of efforts have been made to the parameter study and the sensitivity analyses. The parameters investigated including the concentration of the osmotic solution, diffusion coefficient, permeability of the cell membrane, elastic modulus of the cell wall, critical cell volume etc. The models allow us to quantitatively simulate the time evolution of intracellular and extra-cellular volumes as well as the time evolution of concentrations in each cross-section.

In recent years there has been an increased interest in applying non-parametric methods to real-world problems. Significant research has been devoted to Gaussian processes (GPs) due to their increased flexibility when compared with parametric models. These methods use Bayesian learning, which generally leads to analytically intractable posteriors. This thesis proposes a two-step solution to construct a probabilistic approximation to the posterior. In the first step we adapt the Bayesian online learning to GPs: the final approximation to the posterior is the result of propagating the first and second moments of intermediate posteriors obtained by combining a new example with the previous approximation. The propagation of em functional forms is solved by showing the existence of a parametrisation to posterior moments that uses combinations of the kernel function at the training points, transforming the Bayesian online learning of functions into a parametric formulation. The drawback is the prohibitive quadratic scaling of the number of parameters with the size of the data, making the method inapplicable to large datasets. The second step solves the problem of the exploding parameter size and makes GPs applicable to arbitrarily large datasets. The approximation is based on a measure of distance between two GPs, the KL-divergence between GPs. This second approximation is with a constrained GP in which only a small subset of the whole training dataset is used to represent the GP. This subset is called the em Basis Vector, or BV set and the resulting GP is a sparse approximation to the true posterior. As this sparsity is based on the KL-minimisation, it is probabilistic and independent of the way the posterior approximation from the first step is obtained. We combine the sparse approximation with an extension to the Bayesian online algorithm that allows multiple iterations for each input and thus approximating a batch solution. The resulting sparse learning algorithm is a generic one: for different problems we only change the likelihood. The algorithm is applied to a variety of problems and we examine its performance both on more classical regression and classification tasks and to the data-assimilation and a simple density estimation problems.

The subject-matter of this thesis is the interaction between the Parti Communiste Français and the National Liberation struggle in Algeria , and the debate that ensued within the Party itself. For a detailed study of the Party ' s line on the war, PCF publications were contrasted with the texts produced by the opposition. Three main axes were identified crystallising discussion within the Party during the Algerian war: The relationship between France and Algeria and the Party ' s attitude to the French nation; The nature of the Algerian nation and its genesis; France's military engagement in Algeria. The dichotomy between the Party's national and internationalist responsibilities is shown to have resolved itself by the fundamental integration of the PCF into the political structure and value system of the French Republic. This study demonstrates the birth of a substantial internal opposition to the PCF during the Algerian war.

The thesis addresses the economic impacts of construction safety in Greece. The research involved the development of a methodology for determining the overall costs of safety, namely the sum of the costs of accidents and the costs of safety management failures (with or without accident) including image cost. Hitherto, very little work has been published on the cost of accidents in practical case studies. Moreover, to the author’s belief, no research has been published that seeks to determine in real cases the costs of prevention. The methodology developed is new, transparent, and capable of being replicated and adapted to other employment sectors and to other countries. The methodology was applied to three construction projects in Greece to test the safety costing methodology and to offer some preliminary evidence on the business case for safety. The survey work took place between 1999 and 2001 and involved 27 months of costing work on site. The study focuses on the overall costs of safety that apply to the main (principal) contractor. The methodology is supported by 120 discrete cost categories, and systematic criteria for determining which costs are included (counted) in the overall cost of safety. A quality system (in compliance with ISO9000 series) was developed to support the work and ensure accuracy of data gathering. The results of the study offer some support for the business case for safety. Though they offer good support for the economics of safety as they demonstrate need for cost effectiveness. Subject to important caveats, those projects that appeared to manage safety more cost-effectively achieved the lowest overall safety cost. Nevertheless, results are significantly lower than of other published works for two main reasons; first costs due to damages with no potential to injury were not included and second only costs to main constructor were considered. Study’s results are discussed and compared with other publish works.

This research examines diasporic transformations and the construction of belongings through new technologies of communication by looking at young Kurdish diasporas in Sweden and the UK. It argues that the diaspora concept needs to be reconceptualised in light of digital information and communication technologies and in relation to the imagined community. Empirical evidence from Kurdish diasporas has drawn attention to some missing gaps in the literature. The research asks what it means to be a Kurd in diaspora and what role new media and online communities have in the renegotiation and construction of belongings. By engaging with post-colonial and feminist studies, I unpick fixed categories of identity, belongings and home, and I argue for performativities of those belongings. Based on a year-long ethnographic online study supplemented by offline face-to-face interviews with young Kurds in these locations, and with additional reference to homeland- based Kurds, the research presents three main empirical chapters based on themes derived from the online community’s concerns, and focuses on Swedish, British, and Kurdish forums. The chapters discuss gender and religious tensions; cultural elements and historical suffering; and political engagements in homeland and settlement countries. A fourth chapter takes a step back from online and offline material and examines the comparative approach between the two diasporas, diasporic and homeland Kurds, in both offline and online environments. Against the background of such a close-up comparative study, this research argues for a reconsideration of diasporic formations that are currently fixed between homeland and settlement country, and it presents new perspectives on these that relates to new definitional positions in diasporic formations that have significant implications for the concept of the imagined community.

The attacks against the United States of America (US) on 11 September 2001 paved the way for the coming into effect of much counter-terrorism legislation across the world. Ethiopia is one of the countries that have introduced new legislation on terrorism, which is mainly drawn from the UK and, to a lesser extent, from the US. The aim of this thesis is to comprehensively assess Ethiopia's counter-terrorism legislation in light of the experiences of the UK and the US in dealing with terrorism. Furthermore, this thesis discusses the consequences of ‘copying' Western counter-terrorism legislation into Ethiopian culture, drawing particular attention to the need for a proper balance between legitimate security interests and the protection of fundamental rights. This thesis is organized as follows. The first chapter introduces the significance, methodology, limitation, and scope of the thesis. The second chapter discusses the development of Ethiopian legal system, human rights and counterterrorism measures. Moving forwards, chapter three seeks to analyse two important factors encapsulated within the right to freedom of expression; that is, the content and medium of the expression and the identity of the speaker/publisher. The relevance of these factors in giving effect to the right to freedom of expression is evaluated in light of the need to protect against the incitement and/or encouragement of terrorism. The chapter then deepens its critical assessment by reviewing the difficulty of implementing these factors in Ethiopia. Chapter four seeks to widen the debate by exploring the legal regimes governing intercept evidence - an issue of great importance in terrorism discourse. The chapter critically examines why intercept evidence obtained through a warrant is inadmissible in UK courts. Additionally, this chapter compares the position of the UK with that of the US, isolating areas of similarities and differences with a view to comparing the Ethiopian position on intercept communications. Chapter five focuses on the arrest of individuals on suspicion of terrorism and the length of pre-charge detention under the three countries selected for this research. This chapter will then explore whether there is a need for a watered down version of ‘reasonable suspicion' in terrorism cases. This chapter further considers Ethiopia's position with regard to the level of knowledge required to execute arrests, considering whether Ethiopia could and should reflect on the UK's position in attempting to facilitate a greater accordance with fundamental rights by shortening the 120 days pre-charge detention currently available to police when arresting individuals on suspicion of terrorism. The final chapter draws on the preceding debate and provides the concluding remarks on the thesis.

The hydrocarbon combustion process used to generate electricity releases harmful levels of Carbon, Sulfur and Nitrogen Oxides into the atmosphere. The alternative to environmentally toxic hydrocarbon based fuel, is electricity generated from solar powered microgrids. Solar photovoltaic microgrids represent a clean, renewable and economically viable energy alternative to hydrocarbon based fuel. The microgrid project outlined the specifications required to the charge the battery powered material handling vehicles at General Stamping & Metalworks. The project was designed to replace utility supplied electrical power with a solar microgrid to charge three lead acid type batteries. The solar microgrid project specifies the system requirements, equipment selection and installation methodology. Operational strategies for additional photovoltaic applications within the organization are discussed. Outlined in the report are the costs of installation and return on investment. The project was designed to demonstrate a practical application of microgrids within a manufacturing environment. The goal of the project was to design and build a small scale installation to provide a proof of concept. The overarching goal was to reduce the toxic emissions produced by utility supplied electrical power by installing a solar powered microgrid. The end result of the analysis was that photovoltaic powered microgrids represent a viable energy generating system for battery powered applications. However, based on the regional utility price of .092 $/kWh, the solar installation did not meet the organizations investment acceptance criteria.

<p>Manufacturing today is increasingly competitive and every organization around the world is looking to decrease costs. Maintenance costs generated an average of 28 percent of total manufacturing cost at the Fiat Chrysler Indiana Transmission Plant One in 2018, states Rex White, Head Maintenance Planner at Fiat Chrysler (2018). Maintenance is a supportive expense that does not generate a profit, which makes maintenance an attractive expense to decrease. The cost for components and skilled labor are expensive; however, the downtime is exponentially a larger threat to production cost. One most feared scenarios within a manufacturing facility is that one machine takes down several as it backs up the entire production process.</p><p>The three major types of maintenance are reactive, preventive, and predictive. The research project focused on applying the principles of predictive maintenance to the Fiat Chrysler facilities in Indiana. The report explains the techniques and principles of applying the technology currently available to reduce downtime and maintenance cost. The predictive maintenance procedures and saving are compared with reactive and preventive methods to determine a value of return. The report will examine the benefits of using the Internet of Things technology to create autonomous self-diagnosing smart machines. The predictive maintenance plan in this research illustration will introduce health check equipment used to implement longer lasting machine components. In conclusion, the project developed out an entire predictive maintenance plan to reduce downtime and maintenance costs.<br></p><p></p><br>

Research has consistently demonstrated that exposure to nature, as opposed to urban environments, can be beneficial to health and wellbeing. Among natural landscapes, aquatic (blue space) scenes are among the most preferred and psychologically restorative. Since such landscapes face an increasing range of demands, there is a need to understand how their restorative qualities arise and might be preserved, both in terms of the content of a scene and the psychological processes involved in its interpretation. This thesis examines the cognitive impact of placing artificial (human-made) objects in natural landscapes with and without water. It reports new findings regarding the importance of specific scene content for the restorative potential of blue space. The research also explores some of the underlying psychological processes, addressing novel questions about implicit (subconscious) attitudes towards natural landscapes. It compares implicit and explicit attitudes for the first time in this context. In four studies, methods from social and experimental psychology were used to investigate attitudes towards blue and green space with and without artificial objects. To examine the issues of both artificial objects and implicit attitudes, Study 1 used the Affect Misattribution Procedure (which measures implicit attitudes towards images) to assess whether implicit affect (subconscious positive or negative emotion) differed when the same natural scene was viewed with and without artificial objects. Results showed that introducing objects into natural scenes had a negative impact on implicit affect, particularly when the scene contained water. In order to be able to compare implicit and explicit attitudes, Study 2 examined explicit affective reactions to the images from Study 1 using questions adapted from the Perceived Restorativeness Scale (a measure of the restorative potential of environments). Blue space scenes were rated more highly than green space scenes on all components except aesthetics. The presence of artificial objects resulted in lower ratings on all measures for both blue and green scenes. Study 3 was motivated by an indication in the results from Study 1 that implicit attitudes towards blue and green space may differ. The Affect Misattribution Procedure was used to investigate this for natural landscapes without artificial objects. The study also examined whether implicit attitudes differ according to the type of blue or green environment. Viewing blue space scenes resulted in more positive implicit affect than green space, with sea views generating the most positive implicit affect of all. Following the discovery that artificial objects had a more negative impact on implicit attitudes to blue space than green space, Study 4 tested the possibility that this could be due to such objects being more disruptive to the conceptual coherence of aquatic scenes. The conceptual-semantic congruence of artificial objects was assessed using a lexical decision task, in which participants reacted to object words superimposed on scenes. Results did not support the hypothesis that artificial objects are less congruent in blue space than green space. Overall, the studies provide evidence that placing artificial objects in natural landscapes, particularly aquatic landscapes, adversely affects both implicit and explicit attitudes towards the scenes and may reduce their restorative potential. By successfully combining methods from social and experimental psychology, this research validates novel ways of formulating and addressing questions about why some environments have a more positive psychological impact than others. The new results reported here are not easily explained by current restorative theory, therefore might contribute to refining the theoretical framework within which restorative environments are studied.
