High Royds: an integrated, analytical approach for mapping the unmarked burials of a pauper cemetery

Applying geophysical techniques to detect and map the physical extent of individual unmarked graves proves difficult in many cases. The success of individual geophysical techniques for detecting unmarked graves may be due to a poor understanding of the nature of the graves themselves, the context in which they lie in, and temporal changes to the burial state. Given the unpredictability of these variables, it is surprising that grave prospection is often undertaken using only a single method. This paper presents a multi-methodological survey strategy for detecting unmarked burials and utilises an analytical approach for visualising and evaluating survey results.

Achieving customer satisfaction through integrated products and services: an exploratory study

Complex products such as manufacturing equipment have always needed maintenance and repair services. Increasingly, leading manufacturers are integrating products and services to generate increased revenues and achieve customer satisfaction. Designing integrated products and services requires a different approach to new product development and a clear understanding of how customers perceive the value they obtain from actual usage of products and services—so-called value-in-use. However, there is a lack of research on integrated products and services and how they impact customer satisfaction. An exploratory study was undertaken to understand customers’ views on integrated products and services and the value-in-use derived from such offerings. As value-in-use and its impacts are complicated concepts, a technique from psychology—Repertory Grid Technique—was used to gather data in 33 interviews. The interviews allowed a deep understanding of customer views on integrated products and services to be obtained, and a systematic analysis identified the key attributes of value-in-use. In order to probe further, the data were then analyzed using Honey’s procedure, which identified the impact of the attributes of value-in-use on customer satisfaction. Two key attributes—relational dynamic and access—were found to have the most influence on customer satisfaction. This paper contributes to the innovation field by identifying customer needs for integrated products and services and how these impact customer satisfaction. These are key points and need to be fully considered by managers during new product and service development. Similarly, the paper identifies a number of important areas for further research.

Er:YAl(3)(BO(3))(4) glassy thin films from polymeric precursor and sol-gel methods: Waveguides for integrated optics

This paper presents the characterization of single-mode waveguides for 980 and 1550 nm wavelengths. High quality planar waveguide structure was fabricated from Y(1-x)Er(x)Al(3)(BO(3))(4) multilayer thin films with x = 0.02, 0.05, 0.1, 0.3, and 0.5, prepared through the polymeric precursor and sol-gel methods using spin-coating. The propagation losses of the planar waveguides varying from 0.63 to 0.88 dB/cm were measured at 632.8 and 1550 nm. The photoluminescence spectra and radiative lifetimes of the Er(3+) (4)I(13/2) energy level were measured in waveguiding geometry. For most samples the photoluminescence decay was single exponential with lifetimes in between 640 mu s and 200 mu s, depending on the erbium concentration and synthesis method. These results indicate that Er doped YAl(3)(BO(3))(4) compounds are promising for low loss waveguides. (C) 2009 Elsevier B.V. All fights reserved.

An investigation of worn work roll materials used in the finishing stands of the hot strip mill for steel rolling

The surface failure characteristics of different work roll materials, i.e. High Speed Steel, High Chromium Iron and Indefinite Chill Iron, used in the finishing stands of a hot strip mill have been investigated using stereo microscopy, 3D optical profilometry, scanning electron microscopy and energy dispersive X-ray spectroscopy. The results show that the surface failure mechanisms of work rolls for hot rolling are very complex, involving plastic deformation, abrasive wear, adhesive wear, mechanical and thermal induced cracking, material transfer and oxidation. Despite the differences in chemical composition and microstructure, the tribological response of the different work roll materials was found to be strongly dependent on the material microstructure and especially the presence and distribution of microstructural constituents, such as the different carbide phases and graphite (in the case of Indefinite Chill Iron). Cracking and chipping of the work roll surfaces, both having a negative impact on work roll wear, are strongly influenced by the presence of carbides, carbide networks and graphite in the work roll surface. Consequently, the amount of carbide forming elements as well as the manufacturing process must be controlled in order to obtain an optimised microstructure and a predictable wear rate.

Studies of Design and Assembly Defects on Integrated and Modular Architectures

It is known that despite companies’ efforts to improve the quality of their products, design and assembly defects results in large repair costs both in terms of repair and providing feedback to the origin of the defect. The purpose of this paper is to study these types of defects and the defect rates in design and assembly. The paper presents a web based questionnaire answered by 29 companies. The result shows that the defect rate (defects per product) spanned from 0.01 to 10. Also, design and assembly defects covered 46%, 23% respectively, of all occurred defects. A case study is also presented, performed at a company who recently implemented a modular architecture. In this company, defects from 5 700 integrated product architectures are compared with defects from 431 modular architectures. The average defect rate increased by 21.5% – from 0.65 to 0.79 – when a more modular architecture has been implemented. Furthermore, the study showed that the assembly defects have decreased while the design defects increased. The results presented in this paper will also support the development of the MPV (Module Property Verification) method which is briefly described.

Integrated Product Development in Truck Industry - A Case Study on Product Development Processes

This paper presents the result from a case study at Scania on product development processes. The objective with the case study was to gather information on Scania’s product development process (PDP) including the use of CAD and simulation tools, and project work. The objective was also to find any deviations or different interpretations among the employees on the PDP. To gather the information, semi-structured tape-recorded interviews have been used to ensure that individual interpretations from the interviewees could be gathered. Scania uses a defined and structured PDP which facilitates concurrent and cross-functional work. The PDP is implemented and followed to various degrees. The newly employed personnel may have difficulties with communication, both to find and to give information. Although, newly graduated personnel may find it easier to adapt to changes, and also to use a structured process which they have studied at universities. It was also known during the case study that the PDP is a major support for the newly employed personnel, which in turn decreases the time to get into the same working process as the more experienced personnel. Employees with decades of experience know the right sources from which to both give and gather information. Also, the terminology and definitions in the product development process may not be used as intended. This makes it difficult for other project members or teams who need to interpret the information received. At the same time, the routines among the more experienced personnel, which have been set-up throughout the years, make them more inflexible in adapting changes. The findings in the case study as well as challenges with implementing the PDP are known to Scania and are a part of the continuing work with improvement.

Demonstration of Solar Heating and Cooling System using Sorption Integrated Solar Thermal Collectors

Producing cost-competitive small and medium-sized solar cooling systems is currently a significant challenge. Due to system complexity, extensive engineering, design and equipment costs; the installation costs of solar thermal cooling systems are prohibitively high. In efforts to overcome these limitations, a novel sorption heat pump module has been developed and directly integrated into a solar thermal collector. The module comprises a fully encapsulated sorption tube containing hygroscopic salt sorbent and water as a refrigerant, sealed under vacuum with no moving parts. A 5.6m2 aperture area outdoor laboratory-scale system of sorption module integrated solar collectors was installed in Stockholm, Sweden and evaluated under constant re-cooling and chilled fluid return temperatures in order to assess collector performance. Measured average solar cooling COP was 0.19 with average cooling powers between 120 and 200 Wm-2 collector aperture area. It was observed that average collector cooling power is constant at daily insolation levels above 3.6 kWhm-2 with the cooling energy produced being proportional to solar insolation. For full evaluation of an integrated sorption collector solar heating and cooling system, under the umbrella of a European Union project for technological innovation, a 180 m2 large-scale demonstration system has been installed in Karlstad, Sweden. Results from the installation commissioned in summer 2014 with non-optimised control strategies showed average electrical COP of 10.6 and average cooling powers between 140 and 250 Wm-2 collector aperture area. Optimisation of control strategies, heat transfer fluid flows through the collectors and electrical COP will be carried out in autumn 2014.

Manager's task to support integrated autonomy at the workplace : Results from an intervention

A new managerial task arises in today’s working life: to provide conditions for and influence interaction between actors and thus to enable the emergence of organizing structure in tune with a changing environment. We call this the enabling managerial task. The goal of this paper is to study whether training first line managers in the enabling managerial task could lead to changes in the work for the subordinates. This paper presents results from questionnaires answered by the subordinates of the managers before and after the training. The training was organized as a learning network and consisted of eight workshops carried out over a period of one year (September 2009–June 2010), where the managers met with each other and the researchers once a month. Each workshop consisted of three parts, during three and a half hours. The first hour was devoted to joint reflection on a task that had been undertaken since the last workshop; some results were presented from the employee pre-assessments, followed by relevant theory and illuminating practices, finally the managers created new tasks for themselves to undertake during the following month. The subordinates’ answers show positive change in all of the seventeen scales used to assess it. The improvements are significant in scales measuring the relationship between the manager and the employees, as well as in those measuring interaction between employees. It is concluded that the result was a success for all managers that had the possibility of using the training in their management work.

A Informatização da saúde no Brasil: uma análise multi-paper inspirada na teoria ator-rede

As tecnologias da informação e comunicação (TIC) estão presentes nas mais diversas áreas e atividades cotidianas, mas, em que pesem as ações de governos e instituições privadas, a informatização da saúde ainda é um desafio em aberto no Brasil. A situação atual leva a um questionamento sobre as dificuldades associadas à informatização das práticas em saúde, assim como, quais efeitos tais dificuldades têm causado à sociedade Brasileira. Com objetivo de discutir as questões acima citadas, esta tese apresenta quatro artigos sobre processo de informação da saúde no Brasil. O primeiro artigo revisa a literatura sobre TIC em saúde e baseado em duas perspectivas teóricas – estudos Europeus acerca dos Sistemas de Informação em Saúde (SIS) nos Países em Desenvolvimento e estudos sobre Informação e Informática em Saúde, no âmbito do Movimento da Reforma Sanitária –, formula um modelo integrado que combina dimensões de análise e fatores contextuais para a compreensão dos SIS no Brasil. Já o segundo artigo apresenta os conceitos e teóricos e metodológicos da Teoria Ator-Rede (ANT), uma abordagem para o estudo de controvérsias associadas às descobertas científicas e inovações tecnológicas, por meio das redes de atores envolvidos em tais ações. Tal abordagem tem embasado estudos de SI desde 1990 e inspirou as análises dois artigos empíricos desta tese. Os dois últimos artigos foram redigidos a partir da análise da implantação de um SIS em um hospital público no Brasil ocorrida entre os anos de 2010 e 2012. Para a análise do caso, seguiram-se os atores envolvidos nas controvérsias que surgiram durante a implantação do SIS. O terceiro artigo se debruçou sobre as atividades dos analistas de sistema e usuários envolvidos na implantação do SIS. As mudanças observadas durante a implantação do sistema revelam que o sucesso do SIS não foi alcançado pela estrita e técnica execução das atividades incialmente planejadas. Pelo contrário, o sucesso foi construído coletivamente, por meio da negociação entre os atores e de dispositivos de interessamento introduzidos durante o projeto. O quarto artigo, baseado no conceito das Infraestruturas de Informação, discutiu como o sistema CATMAT foi incorporado ao E-Hosp. A análise revelou como a base instalada do CATMAT foi uma condição relevante para a sua escolha durante a implantação do E-Hosp. Além disso, descrevem-se negociações e operações heterogêneas que aconteceram durante a incorporação do CATMAT no sistema E-Hosp. Assim, esta tese argumenta que a implantação de um SIS é um empreendimento de construção coletiva, envolvendo analistas de sistema, profissionais de saúde, políticos e artefatos técnicos. Ademais, evidenciou-se como os SIS inscrevem definições e acordos, influenciando as preferências dos atores na área de saúde.

Intercomparison of integrated water vapor estimates from multisensors in the amazonian region

Water vapor is an atmospheric component of major interest in atmospheric science because it affects the energy budget and plays a key role in several atmospheric processes. The Amazonian region is one of the most humid on the planet, and land use change is able to affect the hydrologic cycle in several areas and consequently to generate severe modifications in the global climate. Within this context, accessing the error associated with atmospheric humidity measurement and the validation of the integrated water vapor (IWV) quantification from different techniques is very important in this region. Using data collected during the Radiation, Cloud, and Climate Interactions in Amazonia during the Dry-to-Wet Transition Season (RACCI/DRY-TO-WET), an experiment carried out in southwestern Amazonia in 2002, this paper presents quality analysis of IWV measurements from RS80 radiosondes, a suite of GPS receivers, an Aerosol Robotic Network (AERONET) solar radiometer, and humidity sounding from the Humidity Sounder for Brazil (HSB) aboard the Aqua satellite. When compared to RS80 IWV values, the root-mean-square (RMS) from the AERONET and GPS results are of the order of 2.7 and 3.8 kg m(-2), respectively. The difference generated between IWV from the GPS receiver and RS80 during the daytime was larger than that of the nighttime period because of the combination of the influence of high ionospheric activity during the RACCI experiment and a daytime drier bias from the RS80.

Knowledge-based integrated production management model

Purpose - This paper aims to propose a model of production management that integrates knowledge management, as a third dimension, to the production and work dimensions and to identify factors that promote a favorable context for knowledge sharing and results achievement in the production operations shop floor environment.Design/methodology/approach - The model proposed is built from opportunities identified in the literature review.Findings - The factors in the model integrate its three main components: knowledge management, production organization and work organization, providing a representation of the dynamics of the workplace and shop floor environment.Practical implications - The proposed model and its factors allow managers to better understand and to improve the organization activities, because it integrates knowledge management with the production organization and work organization components of traditional models.Originality/value - Literature acknowledges the role of knowledge as competitive advantage, but it is still dealt in an implicit way within the traditional models of production management. This paper proposes a model and factors that provide a favorable context for tacit knowledge sharing and results achievement in the production operations shop floor environment. The model explicitly integrates knowledge management with traditional models' components.

Curva de absorção de água em sementes de atemóia (Annona cherimola Mill. x Annona squamosa L.) cv. Gefner

O presente trabalho teve o objetivo de caracterizar a curva de absorção de água em sementes de atemóia (Annona cherimola Mill x Annona squamosa L.) cv. Gefner, submetidas a três métodos de embebição: sementes submersas em água destilada (MSSA), sementes entre papel de filtro embebido em água destilada acondicionada em caixa tipo gerbox (MPEA) e teste-padrão (MTP), com sementes mantidas em rolo de papel de filtro umedecido em água destilada. O delineamento experimental foi o inteiramente casualizado, com 6 tratamentos e 4 repetições de 25 sementes por parcela, constituídos por três métodos de embebição, empregando-se sementes vivas e mortas. O tempo de embebição entre 27; 34 e 47 horas, nos métodos MTP, MPEA e MSSA, representam indicativo para tratamento de sementes, podendo funcionar como tempo mínimo necessário para embebição em solução com reguladores vegetais. Conclui-se que os métodos que caracterizaram as três fases de absorção de água em sementes de atemóia foram o MTP e MPEA com mudança entre as fases I e II após 27 e 34 horas, respectivamente, atingindo a fase III com 234 horas, o que permite determinar o tempo de imersão para tratamentos pré-germinativos.
