Metodologia para adaptação de microarquiteturas microprogramadas soft-core à uma ISA padrão: estudo do impacto sobre a complexidade de hardware para o padrão MIPS

In academia, it is common to create didactic processors, facing practical disciplines in the area of Hardware Computer and can be used as subjects in software platforms, operating systems and compilers. Often, these processors are described without ISA standard, which requires the creation of compilers and other basic software to provide the hardware / software interface and hinder their integration with other processors and devices. Using reconfigurable devices described in a HDL language allows the creation or modification of any microarchitecture component, leading to alteration of the functional units of data path processor as well as the state machine that implements the control unit even as new needs arise. In particular, processors RISP enable modification of machine instructions, allowing entering or modifying instructions, and may even adapt to a new architecture. This work, as the object of study addressing educational soft-core processors described in VHDL, from a proposed methodology and its application on two processors with different complexity levels, shows that it s possible to tailor processors for a standard ISA without causing an increase in the level hardware complexity, ie without significant increase in chip area, while its level of performance in the application execution remains unchanged or is enhanced. The implementations also allow us to say that besides being possible to replace the architecture of a processor without changing its organization, RISP processor can switch between different instruction sets, which can be expanded to toggle between different ISAs, allowing a single processor become adaptive hybrid architecture, which can be used in embedded systems and heterogeneous multiprocessor environments

Tradução, adaptação cultural e validação do Nonarthritic Hip Score para o Brasil

A avaliação da qualidade de vida tem sido cada vez mais utilizada pelos profissionais da área de saúde para mensurar o impacto de doenças na vida dos pacientes, bem como para avaliar os resultados dos tratamentos realizados. O crescente interesse por protocolos de pesquisa clínica em doenças não degenerativas do quadril tem encontrado muitos obstáculos na avaliação objetiva de seus resultados, principalmente nos estudos de observação de novas intervenções terapêuticas, como a artroscopia. O Nonarthritic Hip Score (NAHS) é um instrumento de avaliação clínica, desenvolvido originalmente em inglês, cujo objetivo é avaliar a função da articulação do quadril em pacientes jovens e fisicamente ativos. O objetivo desse estudo foi traduzir esse instrumento para a língua portuguesa, adaptá-lo para a cultura brasileira e validá-lo para que possa ser utilizado na avaliação de qualidade de vida de pacientes brasileiros com dor no quadril, sem doença degenerativa. A metodologia utilizada é a sugerida por Guillemin et al. (1993) e revisado por Beaton et al. (2000), que propuseram um conjunto de instruções padronizadas para adaptação cultural de instrumentos de qualidade de vida, incluindo cinco etapas: tradução, tradução de volta, revisão pelo comitê, pré-teste e teste, com reavaliação dos pesos dos escores, se relevante. A versão de consenso foi aplicada em 30 indivíduos. As questões sobre atividades esportivas e tarefas domésticas foram modificadas, para melhor adaptação à cultura brasileira. A versão brasileira do Nonarthritic Hip Score (NAHS-Brasil) foi respondida por 64 pacientes com dor no quadril, a fim de avaliar as propriedades de medida do instrumento: reprodutibilidade, consistência interna e validade. A reprodutibilidade foi 0,9, mostrando uma forte correlação; a consistência interna mostrou correlação entre 0,8 e 0,9, considerada boa e excelente; a validade foi considerada respectivamente boa e excelente; a correlação entre NAHS-Brasil e WOMAC foi 0,9; e a correlação entre o NAHS-Brasil e Questionário Algofuncional de Lequesne foi 0,79. O Nonarthritic Hip Score foi traduzido para a língua portuguesa e adaptado à cultura brasileira, de acordo com o conjunto de instruções padronizadas para adaptação cultural de instrumentos de qualidade de vida. Sua reprodutibilidade, consistência interna e validade foram também demonstradas.

Implementation of Multi-Core Processor Based on PLASMA (Most MIPS I) IP Core

Multi-core processors is a design philosophy that has become mainstream in scientific and engineering applications. Increasing performance and gate capacity of recent FPGA devices has permitted complex logic systems to be implemented on a single programmable device. By using VHDL here we present an implementation of one multi-core processor by using the PLASMA IP core based on the (most) MIPS I ISA and give an overview of the processor architecture and share theexecution results.

Environmental and public health issues in Mount Isa : 2007 community survey

This report presents the results of a random telephone survey of 500 adult residents of Mount Isa, conducted in early November 2007. The study was funded by Xstrata Mount Isa Mines. The primary aim of the survey was to collect data about community perceptions and experiences of air quality in Mount Isa and to compare these results with those of a similar survey conducted in 2000 (MacLennan, Lloyd & Hensley, 2000). Both surveys also included questions relating to other aspects of the Mount Isa environment (e.g. water quality, heat, amount of greenery) as well as questions aimed at ascertaining respondents’ general attitudes towards environmental protection.

Basin analysis and economic geology of the Northern Mount Isa Basin

The Mount Isa Basin is a new concept used to describe the area of Palaeo- to Mesoproterozoic rocks south of the Murphy Inlier and inappropriately described presently as the Mount Isa Inlier. The new basin concept presented in this thesis allows for the characterisation of basin-wide structural deformation, correlation of mineralisation with particular lithostratigraphic and seismic stratigraphic packages, and the recognition of areas with petroleum exploration potential. The northern depositional margin of the Mount Isa Basin is the metamorphic, intrusive and volcanic complex here referred to as the Murphy Inlier (not the "Murphy Tectonic Ridge"). The eastern, southern and western boundaries of the basin are obscured by younger basins (Carpentaria, Eromanga and Georgina Basins). The Murphy Inlier rocks comprise the seismic basement to the Mount Isa Basin sequence. Evidence for the continuity of the Mount Isa Basin with the McArthur Basin to the northwest and the Willyama Block (Basin) at Broken Hill to the south is presented. These areas combined with several other areas of similar age are believed to have comprised the Carpentarian Superbasin (new term). The application of seismic exploration within Authority to Prospect (ATP) 423P at the northern margin of the basin was critical to the recognition and definition of the Mount Isa Basin. The Mount Isa Basin is structurally analogous to the Palaeozoic Arkoma Basin of Illinois and Arkansas in southern USA but, as with all basins it contains unique characteristics, a function of its individual development history. The Mount Isa Basin evolved in a manner similar to many well described, Phanerozoic plate tectonic driven basins. A full Wilson Cycle is recognised and a plate tectonic model proposed. The northern Mount Isa Basin is defined as the Proterozoic basin area northwest of the Mount Gordon Fault. Deposition in the northern Mount Isa Basin began with a rift sequence of volcaniclastic sediments followed by a passive margin drift phase comprising mostly carbonate rocks. Following the rift and drift phases, major north-south compression produced east-west thrusting in the south of the basin inverting the older sequences. This compression produced an asymmetric epi- or intra-cratonic clastic dominated peripheral foreland basin provenanced in the south and thinning markedly to a stable platform area (the Murphy Inlier) in the north. The fmal major deformation comprised east-west compression producing north-south aligned faults that are particularly prominent at Mount Isa. Potential field studies of the northern Mount Isa Basin, principally using magnetic data (and to a lesser extent gravity data, satellite images and aerial photographs) exhibit remarkable correlation with the reflection seismic data. The potential field data contributed significantly to the unravelling of the northern Mount Isa Basin architecture and deformation. Structurally, the Mount Isa Basin consists of three distinct regions. From the north to the south they are the Bowthorn Block, the Riversleigh Fold Zone and the Cloncurry Orogen (new names). The Bowthom Block, which is located between the Elizabeth Creek Thrust Zone and the Murphy Inlier, consists of an asymmetric wedge of volcanic, carbonate and clastic rocks. It ranges from over 10 000 m stratigraphic thickness in the south to less than 2000 min the north. The Bowthorn Block is relatively undeformed: however, it contains a series of reverse faults trending east-west that are interpreted from seismic data to be down-to-the-north normal faults that have been reactivated as thrusts. The Riversleigh Fold Zone is a folded and faulted region south of the Bowthorn Block, comprising much of the area formerly referred to as the Lawn Hill Platform. The Cloncurry Orogen consists of the area and sequences equivalent to the former Mount Isa Orogen. The name Cloncurry Orogen clearly distinguishes this area from the wider concept of the Mount Isa Basin. The South Nicholson Group and its probable correlatives, the Pilpah Sandstone and Quamby Conglomerate, comprise a later phase of now largely eroded deposits within the Mount Isa Basin. The name South Nicholson Basin is now outmoded as this terminology only applied to the South Nicholson Group unlike the original broader definition in Brown et al. (1968). Cored slimhole stratigraphic and mineral wells drilled by Amoco, Esso, Elf Aquitaine and Carpentaria Exploration prior to 1986, penetrated much of the stratigraphy and intersected both minor oil and gas shows plus excellent potential source rocks. The raw data were reinterpreted and augmented with seismic stratigraphy and source rock data from resampled mineral and petroleum stratigraphic exploration wells for this study. Since 1986, Comalco Aluminium Limited, as operator of a joint venture with Monument Resources Australia Limited and Bridge Oil Limited, recorded approximately 1000 km of reflection seismic data within the basin and drilled one conventional stratigraphic petroleum well, Beamesbrook-1. This work was the first reflection seismic and first conventional petroleum test of the northern Mount Isa Basin. When incorporated into the newly developed foreland basin and maturity models, a grass roots petroleum exploration play was recognised and this led to the present thesis. The Mount Isa Basin was seen to contain excellent source rocks coupled with potential reservoirs and all of the other essential aspects of a conventional petroleum exploration play. This play, although high risk, was commensurate with the enormous and totally untested petroleum potential of the basin. The basin was assessed for hydrocarbons in 1992 with three conventional exploration wells, Desert Creek-1, Argyle Creek-1 and Egilabria-1. These wells also tested and confrrmed the proposed basin model. No commercially viable oil or gas was encountered although evidence of its former existence was found. In addition to the petroleum exploration, indeed as a consequence of it, the association of the extensive base metal and other mineralisation in the Mount Isa Basin with hydrocarbons could not be overlooked. A comprehensive analysis of the available data suggests a link between the migration and possible generation or destruction of hydrocarbons and metal bearing fluids. Consequently, base metal exploration based on hydrocarbon exploration concepts is probably. the most effective technique in such basins. The metal-hydrocarbon-sedimentary basin-plate tectonic association (analogous to Phanerozoic models) is a compelling outcome of this work on the Palaeo- to Mesoproterozoic Mount lsa Basin. Petroleum within the Bowthom Block was apparently destroyed by hot brines that produced many ore deposits elsewhere in the basin.

The impact of mining and smelting activities on property values : a study of Mount Isa city, Queensland, Australia

Much publicity has been given to the problem of high levels of environmental contaminants, most notably high blood lead concentration levels among children in the city of Mount Isa because of mining and smelting activities. The health impacts from mining-related pollutants are now well documented. This includes published research being discussed in an editorial of the Medical Journal of Australia (see Munksgaard et al. 2010). On the other hand, negative impacts on property prices, although mentioned, have not been examined to date. This study rectifies this research gap. This study uses a hedonic property price approach to examine the impact of mining- and smelting-related pollution on nearby property prices. The hypothesis is that those properties closer to the lead and copper smelters have lower property (house) prices than those farther away. The results of the study show that the marginal willingness to pay to be farther from the pollution source is AUS $13 947 per kilometre within the 4 km radius selected. The study has several policy implications, which are discussed briefly. We used ordinary least squares, geographically weighted regression, spatial error and spatial autoregressive or spatial lag models for this analysis.

Mt Isa Shopping Precinct Survey Report : Consumer Attitudes towards Proposed Extended Trading Hours at Mt Isa

Data was collected to measure shopper’s attitudes toward the proposed Sunday and limited public holiday trading in Mt Isa. Survey questionnaires were conducted between 15th August to 17th August at Kmart Plaza, Woolworths, Miles St. and Mt Isa Plaza. In total, 300 respondents participated in the survey. Overall, the findings suggest that most respondents, especially males, couples with children and fulltime workers, embrace the proposed Sunday and limited holiday trading in Mt Isa. While there are concerns over increasing competition for smaller retailers who already trade on Sundays, a majority of respondents indicated it would suit their lifestyle, be convenient, provide more jobs, increase trade for smaller retailers within the area, reduce queues and congestion, and offer a less expensive grocery shopping. The majority of those shoppers that indicated they currently did some shopping on a Sunday reported they would continue to support smaller retailers who currently trade on Sundays and some public holidays, if changes came about. Those opposed to changes to trading hours also indicated a belief that existing trading hours were sufficient. Most people indicated the proposed extension of trading hours would not harm the community or have a negative, detrimental effect on themselves or their family. The main findings presented in the report are as follows: - 96% of respondents surveyed reported to be local, permanent residents of Mt Isa. - Residents of Mt Isa visited shopping centres and stores on average 2.4 times per week. This mirrors the average Australian shopping behaviour at 2.5 times per week (Roy Morgan Supermarket Monitor) - It was determined that Saturday was the busiest day for shopping with a majority of respondents indicating they visited stores on that day of the week. - 71% of respondents support the proposal of extended trading hours at shopping centres in Mt Isa, 25% oppose and 4% are unsure. - 87% of the respondents agreed that residents of Mt Isa should be allowed the same choice as other regional towns and cities in supporting/opposing changes to trading hours. The remaining 13% expressed a disagreement. - A larger percentage of males supported the proposal for Sunday and limited holiday trading. Of all the males surveyed, 81% were in support, 17% were opposed and 2% unsure. By contrast, 64% of female respondents support the proposal, while 31% oppose it and 5% are unsure. - The highest percentage of support exists in fulltime workers with 85% of those respondents supporting the proposal. In contrast, the lowest percentage of support was found in the non-working respondents, where 62% opposed the application. - 78% of couples living with children at home expressed support for Sunday and limited public holiday trading, while 60% of couples without children also supported the application. - Of the respondents surveyed, virtually none (less than 1%) have travelled outside of Mt Isa on a Sunday to shop. This indicates that due to the remote and isolated location of this town, residents do not have the option to travel reasonable distances in order to access a range of retailers. - 70% of the respondents often find it necessary to do some grocery shopping in Mt Isa on a Sunday. - Convenience is cited as the major reason for support (79%) followed by lifestyle (75%). - The most cited reasons for supporting ‘it would be convenient’ (81%), ‘It may create more jobs’ (77%), ‘It may reduce congestion during busy shopping periods’ (74%, and ‘It would make it easier for working families with kids’ (74%). - The most cited reasons for opposing the proposed changes are that ‘It will disadvantage smaller businesses’ (44%), ‘It is unnecessary’ (29%). - 72% of shoppers who indicated they already undertook some shopping on Sunday, indicated would continue to shop and support smaller retailers. - 98% of respondents indicated they would not change their sporting or social commitment if changes to trading hours were implemented.

Liikuntaharrastusten luonnonvarojen kulutuksen arviointi MIPS-menetelmällä

Tutkielmassa tarkastellaan liikuntaharrastusten luonnonvarojen kulutusta MIPS (material input per service unit, suom. materiaalipanos palvelusuoritetta kohden) -menetelmällä. MIPS-menetelmä perustuu ekotehokkuusajatteluun ja sen tavoitteena on suhteuttaa tuotteen tai palvelun elinkaaren aikainen luonnonvarojen kulutus siitä saatavaan palveluun. Tässä tutkimuksessa tarkastellaan liikuntaharrastusten materiaalivirtoja erilaisissa liikuntapaikoissa yhden henkilön harrastetuntia kohden. Tarkasteltavia liikuntapaikkoja ovat kevyen liikenteen väylä, kuntorata, liikuntasali ja -halli, jäähalli, uimahalli, kuntokeskus sekä lämmitetty ja lämmittämätön tekonurmikenttä. Tutkielman laskelmat perustuvat pääosin tapaustutkimuksiin suomalaisista liikuntapaikoista. Laskelmissa on huomioitu liikuntapaikalle matkustaminen, liikuntapaikan rakentaminen sekä sen ylläpito ja käyttö. Tarkasteltujen liikuntaharrastusten abioottisten luonnonvarojen kulutus vaihteli 1,7 28 kg:n välillä yhden henkilön harrastetuntia kohden. Abioottisten luonnonvarojen kulutukseen vaikutti eniten liikuntapaikalle matkustaminen. Tarkastelluista liikuntaharrastuksista eniten abioottisia luonnonvaroja ja ilmaa kulutti uimahallissa uiminen. Kuntoradoilla ja kevyen liikenteen väylillä harrastettavien ulkoilulajien MIPS-luvut olivat alhaisimmat. Liikuntaharrastukset erosivat toisistaan eniten veden kulutuksessa, jonka MIPS-luvut vaihtelivat 40 ja 1400 kg:n välillä. Korkein veden MIPS-luku oli jäähallissa tapahtuvalla liikunnalla. Ilman kulutus liikuntaharrastuksissa oli 0,1 6,2 kg harrastetuntia kohden. Tulosten perusteella liikuntaharrastusten luonnonvarojen kulutusta voitaisiin tehokkaimmin vähentää kulkemalla liikuntapaikalle henkilöauton sijaan julkisilla kulkuneuvoilla ja hyödyntämällä lähiympäristön tarjoamia liikuntapaikkoja. Myös liikuntapaikkojen kävijämäärien maksimoiminen on tärkeää harrastetunnille kohdistuvien materiaalivirtojen pienentämiseksi. Tutkielma on toteutettu osana FIN-MIPS Kotitalous tutkimushanketta.

MIPS: metal interactions in protein structures

MIPS (metal interactions in protein structures) is a database of metals in the three-dimensional acromolecular structures available in the Protein Data Bank. Bound metal ions in proteins have both catalytic and structural functions. The proposed database serves as an open resource for the analysis and visualization of all metals and their interactions with macromolecular (protein and nucleic acid) structures. MIPS can be searched via a user-friendly interface, and the interactions between metals and protein molecules, and the geometric parameters, can be viewed in both textual and graphical format using the freely available graphics plug-in Jmol. MIPS is updated regularly, by means of programmed scripts to find metal-containing proteins from newly released protein structures. The database is useful for studying the properties of coordination between metals and protein molecules. It also helps to improve understanding of the relationship between macromolecular structure and function. This database is intended to serve the scientific community working in the areas of chemical and structural biology, and is freely available to all users, around the clock, at http://dicsoft2.physics.iisc.ernet.in/mips/.
