Images perceived after chromatic or achromatic contrast sensitivity losses.
2010
Purpose. We simulate how subjects with losses in chromatic and achromatic contrast sensitivity perceive colored images by using the spatiochromatic corresponding pair algorithm. Methods. This is a generalized version of the algorithm by Capilla et al. (J Opt Soc Am (A) 2004;21:176 –186) for simulating color perception of color deviant subjects, which incorporates a simple spatial vision model, consisting of a linear filtering stage, with a band-pass achromatic filter and two low-pass chromatic ones, for the red-green and blue-yellow mechanisms. These filters, except for the global scaling, are the subject’s contrast sensitivity functions measured along the cardinal directions of the color s…
Aspects and issues of daylighting assessment: A review study
2016
Abstract Proper assessment of indoor daylighting conditions can significantly reduce energy consumption due to artificial lighting and can improve indoor visual comfort. This paper gives a critical review of the fundamental aspects of daylighting indices with the aim to provide a broad overview of methods and indices available to assess daylighting from varying points of view. Assessments cover distribution, availability over time and in specific climatic contexts, uniformity in the space, visual comfort issues and the relations between each of these aspects and a proper building and lighting design. A special focus on the assessment of indoor spatial and temporal uniformity is given. An an…
Geological context and micromammal fauna characterisation from the karstic infilling of La Pedrera (Albaida, Valencia, E Spain)
2020
La Pedrera is a new palaeontological site located south of the province of Valencia, between the Betic and Iberian Ranges, in a cavity filled with sediments inside a tufa formation. Roughly 260 fossil remains, corresponding to 14 taxa, have been recovered and studied from Unit III. Six rodents (Microtus sp., M. sp. gr. M. (Terricola) duodecimcostatus-lusitanicus, Microtus sp. gr. M. brecciensis-cabrerae, Arvicola sapidus, Eliomys quercinus, and Apodemus sp. gr. sylvaticusfl avicollis), one lagomorph (Oryctolagus cf. cuniculus), three insectivores (Soricinae indet., Crocidura sp., and Talpa cf. europaea) and four bats (Myotis blythii, Rhinolophus cf. ferrumequinum, Myotis bechsteinii, and Rh…

Palautteen, kannustuksen ja arvostuksen lähteillä : Sanomalehtien Liiton paikallislehtikilpailun rooli paikallisjournalismin kehittämisessä
2011
Sanomalehtien Liitto järjestää vuosittain paikallislehtikilpailun, jonka tarkoitus on parantaa paikallislehtien laatua. Kilpailussa lehdet saavat raadilta kirjallista palautetta sisällöstään, kuvituksestaan, ulkoasustaan ja mielipidekirjoituksistaan. Pro gradu -työssäni tutkin, millainen käytännön merkitys kilpailulla on paikallisjournalismin kehittäjänä. Samalla pohdin lehtien tavoitteita eli sitä, millaista hyvä paikallisjournalismi on. Vuosina 1994–2009 paikallislehtikilpailua tuomaroivat Jyväskylän yliopiston journalistiikan opiskelijat. Selvitän, miten paikallisjournalistit suhtautuivat nuorten tuomareiden palautteisiin. Ovatko lehdet toteuttaneet kehitysehdotuksia ja pitäneet raadin k…
Market Timing with a Robust Moving Average
2015
In this paper we entertain a method of finding the most robust moving average weighting scheme to use for the purpose of timing the market. Robustness of a weighting scheme is defined its ability to generate sustainable performance under all possible market scenarios regardless of the size of the averaging window. The method is illustrated using the long-run historical data on the Standard and Poor's Composite stock price index. We find the most robust moving average weighting scheme, demonstrates its advantages, and discuss its practical implementation.
Technical‐economic evaluation of the effectiveness of measures applied to the artificial lighting system of a school
2021
Ensuring optimum interior lighting is a topic of great importance, as this influences not only the well-being of users but also the optimal performance of visual tasks. Lighting can be natural, but if not sufficient, it can be compensated with artificial lighting. This study highlights a methodology for designing a new lighting system that takes into account both technical and economic aspects. The method was applied to an existing school located in southern Italy, in which the electricity consumption is related to the current lighting system. The school is chosen as being representative of the construction type and layout of many local schools. In addition, the coexistence of several visua…
Automatically Modeling Linguistic Categories in Spanish
2010
This paper presents an approach to process Spanish linguistic categories automatically. The approach is based in a module of a prototype named WIH (Word Intelligent Handler), which is a project to develop a conversational bot. It basically learns category usage sequence in a sentence. It extracts a weighting metric to discriminate most common structures in real dialogs. Such a metric is important to define the preferred organization to be used by the robot to build an answer.
