    Translation has historically been performed by traditional ways like paper dictionary or by asking expert bilinguals who is equipped by strong knowledge. This way of translation was further driven by the digital revolution in the 90s where a huge need of interpreting text from source language and into target language. Twenty years on, translation means continue to flourish, even tending towards machine translation. Consequently, this technology became a part of everyone’s life. This paper is to highlight the advantage of using Google translation website on understanding a short text by secondary school students. Keywords: Google Translate, ESP students, machine translation, translation utilization. DOI: 10.7176/JEP/10-18-14 Publication date:June 30th 2019

    This document is the Pre-Print version of an article first published by Taylor & Francis Group in Journal of Sports Sciences, on December 2016, available online at:http://www.tandfonline.com/doi/full/10.1080/02640414.2016.1267386. The Accepted Manuscript version is under embargo. Embargo end date: 26 June 2018.This study investigated (i) whether the accumulated oxygen deficit (AOD) and curvature constant of the power-duration relationship (W') are different during constant work-rate to exhaustion (CWR) and 3-min all-out (3MT) tests and (ii) the relationship between AOD and W' during CWR and 3MT. Twenty-one male cyclists (age: 40 ± 6 years; maximal oxygen uptake [V̇O2max]: 58 ± 7 ml · kg-1 · min-1) completed preliminary tests to determine the V̇O2-power output relationship and V̇O2max. Subsequently, AOD and W' were determined as the difference between oxygen demand and oxygen uptake and work completed above critical power, respectively, in CWR and 3MT. There were no differences between tests for duration, work, or average power output (P ≥ 0.05). AOD was greater in the CWR test (4.18 ± 0.95 vs. 3.68 ± 0.98 L; P = 0.004), whereas W' was greater in 3MT (9.55 ± 4.00 vs. 11.37 ± 3.84 kJ; P = 0.010). AOD and W' were significantly correlated in both CWR (P < 0.001, r = 0.654) and 3MT (P < 0.001, r = 0.654). In conclusion, despite positive correlations between AOD and W' in CWR and 3MT, between-test differences in the magnitude of AOD and W', suggest that both measures have different underpinning mechanisms.Peer reviewe

    On the inverse of the Caputo matrix exponential

    Full text link
    [EN] Matrix exponentials are widely used to efficiently tackle systems of linear differential equations. To be able to solve systems of fractional differential equations, the Caputo matrix exponential of the index a > 0 was introduced. It generalizes and adapts the conventional matrix exponential to systems of fractional differential equations with constant coefficients. This paper analyzes the most significant properties of the Caputo matrix exponential, in particular those related to its inverse. Several numerical test examples are discussed throughout this exposition in order to outline our approach. Moreover, we demonstrate that the inverse of a Caputo matrix exponential in general is not another Caputo matrix exponential.This work has been partially supported by Spanish Ministerio de Economia y Competitividad and European Regional Development Fund (ERDF) grants TIN2017-89314-P and by the Programa de Apoyo a la Investigacion y Desarrollo 2018 of the Universitat Politecnica de Valencia (PAID-06-18) grant SP20180016.Defez Candel, E.; Tung, MM.; Chen-Charpentier, BM.; Alonso Abalos, JM.

    Twenty years after the beginning of the Doi moi reform (of 1986) in April 2006 the 10th National Congress of the CPV took place, revised the implementation of the 2001-2006 socio-economic plan as well as twenty years of Doi moi, decided on the tasks of the development in the 2006-2010 period, and elected the new leadership by approving 160 members of the CC as well as 14 members of the Politbureau and by reelecting Nong Duc Manh as General Secretary of the CPVCC. The result was disappointing: It is true, on the one hand, that Vietnam is dominated by market economy and by private enterprises; but the leadership continues to be entrusted to the leninist Trinity of local party secretaries, ministerial personal, and CPV-cadres. There is not any private businessman to have been elected for leadership. Externally at least the party is keeping its unflexible leninistic façade. Whether it will internally shift from orthodoxy to a new flexibility - matching the progress of market economy - is a question not to be answered by the Congress

    Aura and Authenticity in the Presentation of UK Literary Figures through the Medium of the Home

    This is an Accepted Manuscript of an article published by Taylor & Francis in Scrutiny2: issues in English Studies in Southern Africa on 16/10/2015, available online: doi:/10.1080/18125441.2015.1072839By exploring case studies from the UK, this paper investigates how the notions of aura and authenticity at literary homes are utilised to create an impact on the understanding of the lives and works of associated writers. The boundaries of this paper have been dictated by its place within twenty-first century manifestations of the survival, conservation and reproduction of literary homes associated with four writers active in the early nineteenth century: Lord Byron, John Keats, Sir Walter Scott and Percy Shelley. Many of the works within the literary house genre highlight the significance of the link between writers and their audiences. However, whereas commentators concentrate on the links being direct, this paper shows that the association is based on narratives validated through those who were subsequently responsible for the houses in conjunction with the expectations of visitors. Consequently, the interpretation prevalent in the houses in the twenty-first century are the result of a long history based on the writers, but influenced by what was, and is, considered their significance by others over approximately two hundred years

    How climate change affects extremes in maize and wheat yield in two cropping regions

The definitive version was published in Journal of Climate 28 (2015): 4653–4687, doi:10.1175/JCLI-D-13-00326.1.Downscaled climate model projections from phase 5 of the Coupled Model Intercomparison Project (CMIP5) were used to force a dynamic vegetation agricultural model (Agro-IBIS) and simulate yield responses to historical climate and two future emissions scenarios for maize in the U.S. Midwest and wheat in southeastern Australia. In addition to mean changes in yield, the frequency of high- and low-yield years was related to changing local hydroclimatic conditions. Particular emphasis was on the seasonal cycle of climatic variables during extreme-yield years and links to crop growth. While historically high (low) yields in Iowa tend to occur during years with anomalous wet (dry) growing season, this is exacerbated in the future. By the end of the twenty-first century, the multimodel mean (MMM) of growing season temperatures in Iowa is projected to increase by more than 5°C, and maize yield is projected to decrease by 18%. For southeastern Australia, the frequency of low-yield years rises dramatically in the twenty-first century because of significant projected drying during the growing season. By the late twenty-first century, MMM growing season precipitation in southeastern Australia is projected to decrease by 15%, temperatures are projected to increase by 2.8°–4.5°C, and wheat yields are projected to decline by 70%. Results highlight the sensitivity of yield projections to the nature of hydroclimatic changes. Where future changes are uncertain, the sign of the yield change simulated by Agro-IBIS is uncertain as well. In contrast, broad agreement in projected drying over southern Australia across models is reflected in consistent yield decreases for the twenty-first century. Climatic changes of the order projected can be expected to pose serious challenges for continued staple grain production in some current centers of production, especially in marginal areas.This work was initiated at the Dissertations Initiative for the Advancement of Climate Change Research (DISCCRS) V Symposium, supported by the U.S. National Science Foundation through collaborative Grants SES-0932916 and SES-0931402.
