Cloud agile manufacturing

This paper proposes a new manufacturing paradigm, we call Cloud Agile Manufacturing, and whose principal objective is to offer industrial production systems as a service. Thus users can access any functionality available in the cloud of manufacturing (process design, production, management, business integration, factories virtualization, etc.) without knowledge — or at least without having to be experts — in managing the required resources. The proposal takes advantage of many of the benefits that can offer technologies and models like: Business Process Management (BPM), Cloud Computing, Service Oriented Architectures (SOA) and Ontologies. To develop the proposal has been taken as a starting point the Semantic Industrial Machinery as a Service (SIMaaS) proposed in previous work. This proposal facilitates the effective integration of industrial machinery in a computing environment, offering it as a network service. The work also includes an analysis of the benefits and disadvantages of the proposal.

Culture Industries in a Postindustrial Age: Entertainment, Leisure, Creativity, Design

This article reviews the evolution of the concept of culture industries, when neither industry nor culture themselves are today what they were at the time when the term was coined. It attempts to explain the dilution of the term into more nebulous terms (“leisure industries,” “entertainment industries” or “creative industries”) and suggests new challenges for the research on culture industries. What is at stake is no longer an application of a Fordist production to culture, a one-directional mass communication and a mediation by experts, but rather: (1) a cultural experience which is no longer clearly separated from other activities (leisure in general, consumption and even work); (2) the communicative explosion of all industrial production in a media environment, where industrialized symbolic products are mixed with culturalized industrial products; and (3) the empowerment of the recipient, which on one hand ignores the traditional experts and on the other leads to post-productive (recreational and even creative) cultural practices.

A expressão arquitétónica na escultura moderna

This dissertation seeks to map out a route in sculptural production and artistic modernism, through the questioning of some of the different ways of approaching the concept of sculpture and architecture that were explored during the twentieth century. Based on the concepts of sculpture, architecture and space — which are proposed as a complementary perspectives to the analysis of our study object — a reflection is develop, in which explores the tension between a sculptural model and an architectural model. This research aims to identify and understand some presences of architectural expression in Modern sculpture. In this context, we will see that this has influenced other movements to the present day, but also a result of a historical situation. The relationship between sculpture and architecture has taken different forms and functions over time and the means of technological and industrial production were seen as a way of transformation of twentieth-century art. The first part of this dissertation focuses on several Modernism definition proposals. The second part presents the first vanguards proposals, and the transformations in the way of understanding sculpture. In the third part, the most current trends, which provide a reference for resolving the tension between the listed models, are addressed. Going against the linear evolution of reading, this paper proposes an interpretation that is based on the identification from a processing of the sculpture conception

The transformation of agriculture in Ukraine: From collective farms to agroholdings. OSW Commentary No. 127, 06.02.2014

In recent years, Ukraine’s agriculture has been consistently improving and has been the only part of the country’s economy to buck the recession. According to preliminary estimates, in 2013 agricultural production increased by 13.7% - in contrast to a 4.7% decline in the industrial sector. According to official statistics, Ukraine’s industrial production was up 40% in the final months of 2013 when compared to the same period of 2012. This translated into an unexpected gain in fourth-quarter GDP growth (+3.7%) and prevented an annual drop in GDP. Crop production, and particularly the production of grain, hit a record high: in 2013, Ukraine produced 63 million tonnes of grain, outperforming its best ever harvest of 2011 (56.7 million tonnes). The value of Ukraine’s agricultural and food exports increased from US$4.3 billion in 2005 to US$17.9 billion in 2012, and currently accounts for a quarter of Ukraine’s total exports. Economic forecasts suggest that in the current marketing year (July 2013 - June 2014) Ukraine will sell more than 30 million tonnes of grain to foreign markets, making it the world’s second biggest grain exporter, after the United States.

Ukrainian economy overshadowed by war. OSW Commentary No. 148, 08.10.2014

Ukraine’s financial results over the past few months prove that the economic crisis which has been ongoing since mid 2012 has exacerbated. According to data from the Ukrainian Ministry of Economy, Gross Domestic Product for the first six months of 2014 shrank by 3%. In the second quarter, it fell by 4.6%1 and may further be reduced by as much as 8–10% over the year as a whole. After the first six months of this year, the balance of payments deficit reached US$4.3 billion. After deflation last year, prices grew by 12%, and the hryvnia dropped to a historic low. Although a surplus was seen in Ukrainian foreign trade in goods and services, reaching over US$3 billion at the end of June, its trade volume is shrinking. The main reason behind this deteriorating situation is the actions taken by Russia. Moscow has been fomenting the conflict in Donbas since April, has consistently imposed embargoes on imports of more and more Ukrainian goods and cut gas supplies to Ukraine in June. This has forced the government to focus on the current management of state finances and to carry out budget sequestration twice this year. The government has also used this as an excuse not to implement necessary systemic reforms. The increasing share of military expenditure, the shrinking exports (-5% in the first six months), including in particular to Russia, which until recently was Ukraine’s key trade partner, and the rapid fall in industrial production and investments have all made the situation even worse. All that saves Ukraine from an economic collapse is the loan from the International Monetary Fund and higher taxes, which allows the government to maintain budget liquidity. However, if the conflict in Donbas lasts longer and if Russia continues its economic blackmail, including withholding gas supplies, the economic crisis may prove to be long-lasting.

Russia in Crisis: Year One. OSW Report, January 2010

Economic conditions which had favoured Russia’s development suddenly changed in mid-2008. The Russian economy was hit, on the one hand, by a drastic slump in oil prices (which fell from nearly US$150 to US$50 between July 2008 and January 2009), and on the other by the outflow of investors (a net of US$130 billion of capital left Russia in the fourth quarter of 2008). Within several months, the financial crisis became an economic crisis affecting the entire economy. The financial reserves accumulated in times of prosperity (more than US$162 billion in the stabilisation funds and nearly US$598 billion in the currency and gold reserve) alleviated the negative impact of the crisis, although this failed to prevent the deep declines in macroeconomic indicators. Russia is one of the states most severely affected by the crisis. In the first half of 2009, its GDP fell by 10.4% compared to the same period in the previous year, while industrial production dropped by nearly 15%, and a decrease in investments of over 18% was reported. The poor economic performance has strongly affected the Russian budget, which reported a deficit for the first time in ten years in 2009. During the first year of the crisis (August 2008 – September 2009), Russia’s financial reserves were seriously reduced as a result of the government’s anti-crisis policy and interventions from the central bank: the reserve fund decreased by nearly 45% to US$76 billion, and the central bank’s reserves shrunk by nearly US$200 billion to US$409 billion. Meanwhile, however, the money in the National Welfare Fund, which had been intended almost entirely to subsidise the Pensions Fund between 2010 and 2015, rose almost three-fold (to US$90 billion). According to government forecasts, the money from the reserve fund is also supposed to be spent fully in 2010. The financial crisis has triggered a dynamic outflow of capital from the Russian market. So-called speculative capital was the first to demonstrate the lack of confidence in the Russian market. In the first half of 2009, the growth rate of long-term investments also decreased noticeably, although no spectacular withdrawal of direct investments from Russia has been observed. The economic crisis has also halted the foreign expansion of Russian private capital, while state-owned capital strengthened its position as an investor. Russia’s raw materials companies continue to be the main category of foreign investors; however, new technologies are gaining prominence as the second main direction of Russian investments.

Characterization of Pantoea dispersa UQ68J: producer of a highly efficient sucrose isomerase for isomaltulose biosynthesis

Aims: Isolation, identification and characterization of a highly efficient isomaltulose producer. Methods and Results: After an enrichment procedure for bacteria likely to metabolize isomaltulose in sucrose-rich environments, 578 isolates were screened for efficient isomaltulose biosynthesis using an aniline/diphenylamine assay and capillary electrophoresis. An isolate designated UQ68J was exceptionally efficient in sucrose isomerase activity. Conversion of sucrose into isomaltulose by UQ68J (enzyme activity of 90-100 U mg(-1) DW) was much faster than the current industrial strain Protaminobacter rubrum CBS574.77 (41-66 U mg(-1) DW) or a reference strain of Erwinia rhapontici (0.3-0.9 U mg(-1) DW). Maximum yield of isomaltulose at 78-80% of supplied sucrose was achieved in less than half the reaction time needed by CBS574.77, and the amount of contaminating trehalulose (4%) was the lowest recorded from an isomaltulose-producing microbe. UQ68J is a Gram negative, facultatively anaerobic, motile, noncapsulate, straight rod-shaped bacterium producing acid but no gas from glucose. Based on 16S rDNA analysis UQ68J is closest to Klebsiella oxytoca, but it differs from Klebsiella in defining characteristics and most closely resembles Pantoea dispersa in phenotype. Significance and Impact of Study: This organism is likely to have substantial advantage over previously characterized sucrose isomerase producers for the industrial production of isomaltulose.

Characterization of the highly efficient sucrose isomerase from Pantoea dispersa UQ68J and cloning of the sucrose isomerase gene

Sucrose isomerase (SI) genes from Pantoea dispersa UQ68J, Klebsiella planticola UQ14S, and Erwinia rhapontici WAC2928 were cloned and expressed in Escherichia coli. The predicted products of the UQ14S and WAC2928 genes were similar to known SIs. The UQ68J SI differed substantially, and it showed the highest isomaltulose-producing efficiency in E. coli cells. The purified recombinant WAC2928 SI was unstable, whereas purified UQ68J and UQ14S SIs were very stable. UQ68J SI activity was optimal at pH 5 and 30 to 35 degrees C, and it produced a high ratio of isomaltulose to trehalulose (> 22:1) across its pH and temperature ranges for activity (pH 4 to 7 and 20 to 50 degrees C). In contrast, UQ14S SI showed optimal activity at pH 6 and 35 degrees C and produced a lower ratio of isomaltulose to trehalulose (< 8:1) across its pH and temperature ranges for activity. UQ68J SI had much higher catalytic efficiency; the K-m was 39.9 mM, the V-max was 638 U mg(-1), and the K-cat/K-m was 1.79 x 104 M-1 s(-1), compared to a K-m of 76.0 mM, a V-max. of 423 U mg(-1), and a K-cat/K-m of 0.62 x 104 M-1 s(-1) for UQ14S SI. UQ68J SI also showed no apparent reverse reaction producing glucose, fructose, or trehalulose from isomaltulose. These properties of the P. dispersa UQ68J enzyme are exceptional among purified SIs, and they indicate likely differences in the mechanism at the enzyme active site. They may favor the production of isomaltulose as an inhibitor of competing microbes in high-sucrose environments, and they are likely to be highly beneficial for industrial production of isomaltulose.

The effects of changes in recycling patterns on United Kingdom resource consumption

Recycling, substitution and product life extension are identified as significant factors contributing to an extension of the time to exhaustion of industrially Dnportant materials. A quantitative assessment of the significance of virtually all materials to the U.K. is made. Copper is identified as one of the most important materials deserving of further investigation into potential resource savings through increased recycling. The other factors listed above are accounted for in the modelling technique employed. United Kingdom copper flows are qualitatively and statistically described for the years 1949 - 1976. Less accurate statistics are developed for 1922 - 1948. Adaptive expectations type causal models of total, unalloyed, and alloyed copper demand are successfully constructed and are used to generate future scenarios. Evidence is demonstrated for a break in the historical link between U.K. copper demand and industrial production. Simple causal models of potential copper scrap supply are constructed and a comparison made with actual old scrap withdrawals. Accurate adaptive expectations type models of total scrap demand are developed, but no conclusion is reached about the price elasticity of scrap demand. Various scenarios of copper goods demand are forecast and their effect on copper scrap demand. The potential to recover up to an extra 100.000 tonnes/year of generally lower grade old scrap is identified. Policy options are examined and the following recommendations made: 1) A total investment of up to £67 million in secondary refining capacity by the year 2000 is needed. 2) The copper scrap content of copper bearing goods should be specified to aid recovery. 3) A U.K. copper scrap buffer stock scheme would be advantageous for the secondary copper industry. Finally the methodology used is summarised for potential application to other materials.

An investigation of thin amorphous carbon-based sputtered coatings for MEMS and micro-engineering applications

The work presented in this thesis describes an investigation into the production and properties of thin amorphous C films, with and without Cr doping, as a low wear / friction coating applicable to MEMS and other micro- and nano-engineering applications. Firstly, an assessment was made of the available testing techniques. Secondly, the optimised test methods were applied to a series of sputtered films of thickness 10 - 2000 nm in order to: (i) investigate the effect of thickness on the properties of coatingslcoating process (ii) investigate fundamental tribology at the nano-scale and (iii) provide a starting point for nanotribological coating optimisation at ultra low thickness. The use of XPS was investigated for the determination of Sp3/Sp2 carbon bonding. Under C 1s peak analysis, significant errors were identified and this was attributed to the absence of sufficient instrument resolution to guide the component peak structure (even with a high resolution instrument). A simple peak width analysis and correlation work with C KLL D value confirmed the errors. The use of XPS for Sp3/Sp2 was therefore limited to initial tentative estimations. Nanoindentation was shown to provide consistent hardness and reduced modulus results with depth (to < 7nm) when replicate data was suitably statistically processed. No significant pile-up or cracking of the films was identified under nanoindentation. Nanowear experimentation by multiple nanoscratching provided some useful information, however the conditions of test were very different to those expect for MEMS and micro- / nano-engineering systems. A novel 'sample oscillated nanoindentation' system was developed for testing nanowear under more relevant conditions. The films were produced in an industrial production coating line. In order to maximise the available information and to take account of uncontrolled process variation a statistical design of experiment procedure was used to investigate the effect of four key process control parameters. Cr doping was the most significant control parameter at all thicknesses tested and produced a softening effect and thus increased nanowear. Substrate bias voltage was also a significant parameter and produced hardening and a wear reducing effect at all thicknesses tested. The use of a Cr adhesion layer produced beneficial results at 150 nm thickness, but was ineffective at 50 nm. Argon flow to the coating chamber produced a complex effect. All effects reduced significantly with reducing film thickness. Classic fretting wear was produced at low amplitude under nanowear testing. Reciprocating sliding was produced at higher amplitude which generated three body abrasive wear and this was generally consistent with the Archard model. Specific wear rates were very low (typically 10-16 - 10-18 m3N-1m-1). Wear rates reduced exponentially with reduced film thickness and below (approx.) 20 nm, thickness was identified as the most important control of wear.

Business cycles, long waves, and company langevity in Birmingham area metal industries 1780-1980

This doctoral thesis originates from an observational incongruence between the perennial aims and aspirations of economic endeavour and actually recorded outcomes, which frequently seem contrary to those intended and of a recurrent, cyclical type. The research hypothesizes parallel movement between unstable business environments through time, as expressed by periodically fluctuating levels of economic activity, and the precipitation rates of industrial production companies. A major problem arose from the need to provide theoretical and empirical cohesion from the conflicting, partial and fragmented interpretations of several hundred historians and economists, without which the research question would remain unanswerable. An attempt to discover a master cycle, or superimposition theorem, failed, but was replaced by minute analysis of both the concept of cycles and their underlying data-bases. A novel technique of congregational analysis emerged, resulting in an integrated matrix of numerical history. Two centuries of industrial revolution history in England and Wales was then explored and recomposed for the first time in a single account of change, thereby providing a factual basis for the matrix. The accompanying history of the Birmingham area provided the context of research into the failure rates and longevities of firms in the city's staple metal industries. Sample specific results are obtained for company longevities in the Birmingham area. Some novel presentational forms are deployed for results of a postal questionnaire to surviving firms. Practical demonstration of the new index of national economic activity (INEA) in relation to company insolvencies leads to conclusions and suggestions for further applications of research into the tempo of change, substantial Appendices support the thesis and provide a compendium of information covering immediately contiguous domains.

The evolution of logistics service providers and the role of Internet-based applications in facilitating global operations

The need for global logistics services has increased dramatically and become extremely complex and dynamic as a result of a number of changes in manufacturing and in industrial production. In response, the logistics industry is changing in a variety of ways, including mergers to form integrated transportation service providers, outsourcing and increased use of information technology. The aim of this chapter is to provide an overview of the evolution and the most important trends in the logistics services provider (LSP) industry. Specific emphasis will be given to the role of Internet-based applications. Within this context, the chapter will also present the role of logistics e-marketplaces. In particular, based on the secondary research of currently existing logistics on-line marketplaces, an analysis and classification of them is provided with the aim of identifying service gaps. The analysis reveals that logistics electronic marketplaces, despite the increased range of services currently offered, still face limitations with reference to integrated customs links or translation services, which both reduce the efficiency of global operations.

A framework for transforming, analyzing, and realizing software designs in unified modeling language

Unified Modeling Language (UML) is the most comprehensive and widely accepted object-oriented modeling language due to its multi-paradigm modeling capabilities and easy to use graphical notations, with strong international organizational support and industrial production quality tool support. However, there is a lack of precise definition of the semantics of individual UML notations as well as the relationships among multiple UML models, which often introduces incomplete and inconsistent problems for software designs in UML, especially for complex systems. Furthermore, there is a lack of methodologies to ensure a correct implementation from a given UML design. The purpose of this investigation is to verify and validate software designs in UML, and to provide dependability assurance for the realization of a UML design.^ In my research, an approach is proposed to transform UML diagrams into a semantic domain, which is a formal component-based framework. The framework I proposed consists of components and interactions through message passing, which are modeled by two-layer algebraic high-level nets and transformation rules respectively. In the transformation approach, class diagrams, state machine diagrams and activity diagrams are transformed into component models, and transformation rules are extracted from interaction diagrams. By applying transformation rules to component models, a (sub)system model of one or more scenarios can be constructed. Various techniques such as model checking, Petri net analysis techniques can be adopted to check if UML designs are complete or consistent. A new component called property parser was developed and merged into the tool SAM Parser, which realize (sub)system models automatically. The property parser generates and weaves runtime monitoring code into system implementations automatically for dependability assurance. The framework in the investigation is creative and flexible since it not only can be explored to verify and validate UML designs, but also provides an approach to build models for various scenarios. As a result of my research, several kinds of previous ignored behavioral inconsistencies can be detected.^

Development of sustainable, innovative and energy-efficient concrete, based on the integration of all-waste materials: SUS-CON panels for building applications

The building sector requires the worldwide production of 4 billion tonnes of cement annually, consuming more than 40% of global energy and accounting for about 8% of the total CO2 emissions. The SUS-CON project aimed at integrating waste materials in the production cycle of concrete, for both ready-mixed and pre-cast applications, resulting in an innovative light-weight, ecocompatible and cost-effective construction material, made by all-waste materials and characterized by enhanced thermal insulation performance and low embodied energy and CO2. Alkali activated “cementless” binders, which have recently emerged as eco-friendly construction materials, were used in conjunction with lightweight recycled aggregates to produce sustainable concrete for a range of applications. This paper presents some results from the development of a concrete made with a geopolymeric binder (alkali activated fly ash) and aggregate from recycled mixed plastic. Mix optimisation was achieved through an extensive investigation on production parameters for binder and aggregate. The mix recipe was developed for achieving the required fresh and hardened properties. The optimised mix gave compressive strength of about 7 MPa, flexural strength of about 1.3 MPa and a thermal conductivity of 0.34 W/mK. Fresh and hardened properties were deemed suitable for the industrial production of precast products. Precast panels were designed and produced for the construction of demonstration buildings. Mock-ups of about 2.5 x 2.5 x 2.5 m were built at a demo park in Spain both with SUS-CON and Portland cement concrete, monitoring internal and external temperatures. Field results indicate that the SUS-CON mock-ups have better insulation. During the warmest period of the day, the measured temperature in the SUS-CON mock-ups was lower.

British economic growth 1270-1870

This is a definitive new account of Britain's economic evolution from a backwater of Europe in 1270 to the hub of the global economy in 1870. For the first time Britain's national accounts are reconstructed right back into the thirteenth century to show what really happened quantitatively during the centuries leading up to the Industrial Revolution. Contrary to traditional views of the earlier period as one of Malthusian stagnation, they reveal how the transition to modern economic growth built on the earlier foundations of a persistent upward trend in GDP per capita which doubled between 1270 and 1700. Featuring comprehensive estimates of population, land use, agricultural production, industrial and service-sector production and GDP per capita, as well as analysis of their implications, this is an essential reference work for those interest in British economic history and the origins of modern economic growth more generally.
