Ensayos comparativos a escala real de cubierta formada por correas Z conformadas en frío
Authors: Loureiro A. , Calvo R.
Published: June 2016

La utilización de correas Z conformadas en frio es muy habitual en construcción industrial. No obstante, debido al alto grado de incertidumbre de este tipo de estructuras y elementos, y a su tendencia a sufrir fenómenos de inestabilidad local, resulta muy interesante contar con resultados de ensayos reales.

En este artículo, se aportan los resultados de dos ensayos de cubiertas Deck a escala real. La cubierta se carga mediante balsa de agua hasta llegar al colapso de la estructura, determinando tanto su resistencia última, como el comportamiento hasta este punto. Adicionalmente se comparan los resultados de los ensayos con los obtenidos mediante diferentes metodologías habituales en el ámbito de la ingeniería estructural.

Se concluye que el comportamiento en el rango lineal durante los ensayos es muy similar al predicho analíticamente, y se observa una muy alta resistencia última hasta el colapso de la estructura en ambos ensayos.

Authors: Ibañez Rodrigo , Soria Alvaro , Teyseyre Alfredo Raul , Berdun Luis , Campo Marcelo Ricardo
Published: June 2016

Progress and technological innovation achieved in recent years, particularly in the area of entertainment and games, have promoted the creation of more natural and intuitive human-computer interfaces. For example, natural interaction devices such as Microsoft Kinect allow users to explore a more expressive way of human-computer communication by recognizing body gestures. In this context, several Supervised Machine Learning techniques have been proposed to recognize gestures. However, scarce research works have focused on a comparative study of the behavior of these techniques. Therefore, this chapter presents an evaluation of 4 Machine Learning techniques by using the Microsoft Research Cambridge (MSRC-12) Kinect gesture dataset, which involves 30 people performing 12 different gestures. Accuracy was evaluated with different techniques obtaining correct-recognition rates close to 100% in some results. Briefly, the experiments performed in this chapter are likely to provide new insights into the application of Machine Learning technique to facilitate the task of gesture recognition.

Authors: Cardoso Pedro , Rodrigues João , Monteiro Jânio , Sousa Luís
Published: June 2016

As computing equipment become ubiquitous, a new set of interfacing devices need to be developed and properly adapted to the conditions where this equipment is to be used. Interacting with machines might present difficulties relative to the handiness of common interfacing devices, when wearing certain clothes, doing certain dirty jobs, or when they are used by people with accessibility needs. In the last decades a new set of input devices were made available, including 3D sensors, which allow machine interacting without the need of touching any device. This chapter presents two prototype solutions supported by one of this 3D sensors, the Leap Motion, to manage appliances and other devices in a building and for the picking and loading of vehicles in a warehouse. The first case is contextualized in the area of the IoT and load scheduling of appliances, as a decisive factor in reduction of the buildings' electrical costs. The second case is presented as a solution to integrate the distribution of fresh and frozen goods where workers use thick clothes/gloves to carry out their work.

Authors: Güngör Ayşegül Sağkaya , Çadırcı Tuğçe Ozansoy , Köse Şirin Gizem
Published: June 2016

Advergaming serves as a new and valuable form of online advertising, especially for companies that target young consumers. This study examines the impacts of cognitive overload with placement prominence on respondents' brand recall, recognition and brand attitudes. An experiment was conducted on a group of university students with an exposure to an advergame under low and high cognitive load stimulus. Results showed that brands that are placed prominently are better recalled in high cognitive load condition. However, cognitive overload doesn't have any significant effect on the recognition of the main brand in which the advergames is specifically designed. Moreover, there is no difference in recall of subtly placed products in low and high cognitive load conditions. However, there is a significant difference in brand attitude in different cognitive loads. The study both investigated the context of advergames and as well in-game advertising (IGA) situations. The results of the study have both practical and theoretical implications.

Authors: Al-Mansour Ebtihal Abdullah , Jaffar Arfan
Published: June 2016

Malignant Melanoma is one of the rare and the deadliest form of skin cancer if left untreated. Death rate due to this cancer is three times more than all other skin-related malignancies combined. Incidence rates of melanoma have been increasing, especially among young adults, but survival rates are high if detected early. There is a need for an automated system to assess a patient's risk of melanoma using digital dermoscopy, that is, a skin imaging technique widely used for pigmented skin lesion inspection. Although many automated and semi-automated methods are available to diagnose skin cancer but each has its own limitations and there is no final, state-of-the art technique to date which is able to be implemented in real scenario. This survey paper is based on techniques used to segment the skin cancer, analysis of their merits and demerits and their applications on advanced imaging techniques.

Adaptive Routing for an Ad Hoc Network Based on Reinforcement Learning
Authors: Desai Rahul , Patil B.P.
Published: June 2016

This paper describes and evaluates the performance of various reinforcement learning algorithms with shortest path algorithms that are widely used for routing packets throughout the network. Shortest path routing is simplest policy used for routing the packets along the path having minimum number of hops. In high traffic or high mobility conditions, the shortest path gets flooded with huge number of packets and congestions occurs, so such shortest path does not provide the shortest path and increases delay for reaching the packets to the destination. Reinforcement learning algorithms are adaptive algorithms where the path is selected based on the traffic present on the network at real time. Thus they guarantee the least delivery time to reach the packets to the destination. Analysis is done on a 6-by-6 irregular grid and sample ad hoc network shows that performance parameters used for judging the network such as packet delivery ratio and delay provide optimum results using reinforcement learning algorithms.
An Efficient QoS Routing Protocol for Real Time Applications in MANET
Authors: Srivastava Prakash , Kumar Rakesh
Published: June 2016

Multimedia applications over Internet are rising day by day hence stringent requirements of bandwidth and delay is an important issue. This paper is focused on QoS aware routing which provides optimal routes as a function of parameters like bandwidth, delay, packet loss etc. Thea authors' approach involves estimation of node bandwidth, delay and link expiration time at every node. The link expiration time metric is also considered for efficient route discovery to determine forecasting of route stability in near future and hence reliable route is identified. Existing link failure strategy involves frequent route discoveries which incurs high routing overhead and increased end-to-end delay. In this paper, efficient link failure strategy is also incorporated by utilizing multiple alternate paths in case of link failure which is determined with the help of signal intensity level to provide prediction before link break up. Performance of proposed approach is analyzed through simulation and validated analytically. Results show that the authors' approach has been found outperforming to existing approaches.

Tampering Localization in Double Compressed Images by Investigating Noise Quantization
Authors: Mire Archana Vasant , Dhok Sanjay B. , Mistry Naresh J. , Porey Prakash D.
Published: June 2016

Noise is uniformly distributed throughout an untampered image. Tampering operations destroy this uniformity and introduce inconsistency in the tampered region. Hence, noise discrepancy is often investigated in forensic analysis of uncompressed digital images. However, noise in compressed images has got very little attention from the forensic experts. The JPEG compression process itself introduces uniform quantization noise throughout an image, making this investigation difficult. In this paper, the authors have proposed a new noise compression discrepancy model, which blindly estimates this discrepancy in the compressed images. Considering the smaller tampered region, SVM classifier was trained using noise features of test sub-images and its nonaligned recompressed versions. Each of the test sub-images was further classified using this classifier. Experimental results show that in some cases, the proposed approach can achieve better performance compared with other JPEG artefact based techniques.

Authors: Pintro Jose Carlos
Published: June 2016

Os efeitos da toxicidade de duas espécies químicas de alumínio (Al) - monomérica e polimérica - sobre o crescimento de plantas de milho, Zea mays L. (Poaceae), foram estudados em solução nutritiva de baixo valor de força iônica. Com o aumento da atividade de Al em solução nutritiva, houve redução da produção de massa seca da parte aérea e do comprimento da raiz principal. Os efeitos da toxicidade de Al foram mais intensos nas raízes do que na parte aérea. As raízes laterais também foram sensíveis ao Al. Com o aumento da atividade de Al, houve redução nos valores de comprimento. A redução do comprimento foi de 80% nos 2 cm iniciais no sentido da base para o ápice da raiz principal na atividade de 3,9 µM de Al em relação ao tratamento sem Al. As duas espécies de Al apresentaram nível de toxicidade semelhante

Published: June 2016

Este trabalho foi desenvolvido com o objetivo de entender o envolvimento dos tricomas glandulares tipo IV, contendo acilaçúcares, na resistência de tomateiro à Bemisia argentifolii. Os genótipos utilizados foram: Lycopersicon esculentum ‘TOM-584’, desprovido de acilaçúcares e de tricomas tipo IV; L. pennellii ‘LA-716’, rico em acilaçúcares e em tricomas tipo IV; bem como suas plantas F2: BPX-370#30 e BPX-370#79. O experimento foi instalado em delineamento inteiramente casualizado com quatro tratamentos (genótipos), três e seis repetições dos parentais e dos clones F2, respectivamente. As quantificações dos tricomas tipo IV foram feitas do lado abaxial dos folíolos, em 20 cortes paradérmicos/planta, distribuídos em cinco folíolos/planta e quatro cortes/folíolo. As informações sobre os teores de acilaçúcares, bem como dos números de adultos mortos e ninfas vivas de mosca branca dos genótipos em teste, foram obtidas de outros estudos. Foram realizados contrastes entre as médias dos genótipos F2, para a densidade de tricomas, número de adultos mortos e de ninfas vivas de mosca branca. Não houve influência do tricoma tipo IV na resistência do tomateiro à mosca branca. A presença de adultos mortos do inseto nas plantas com este tipo de tricoma, bem como a ausência ou pequena quantidade de ninfas vivas, são explicadas pela ação dos acilaçúcares carreados por esse tipo de tricoma

Foram estudados os efeitos da agricultura irrigada nas propriedades químicas de solos da região do Submédio São Francisco, Norte do Estado da Bahia. Foram selecionadas seis áreas, três em LATOSSOLO AMARELO do Projeto Senador Nilo Coelho, no município de Casa Nova (BA) e três em ARGISSOLO AMARELO Fragipânico do Perímetro Irrigado Curaçá, município de Juazeiro (BA), envolvendo talhões não irrigados e irrigados por diferentes períodos e sistemas de irrigação. Os solos foram morfologicamente caracterizados e, nas amostras de cada horizonte, foram determinados pH, carbono orgânico, fósforo extraível, bases trocáveis, capacidade de troca catiônica, saturação por bases e por alumínio. As propriedades químicas foram afetadas diferentemente em função do manejo adotado. Nas áreas de culturas permanentes e irrigação por aspersão ou gotejamento houve uma melhoria na fertilidade dos solos, com aumento no pH e bases trováveis e redução na saturação por alumínio dos horizontes superficiais. Na área com culturas anuais e irrigação por sulco, observou-se redução da soma e da saturação por bases e aumento na saturação por alumínio. Não foi observada nenhuma tendência de salinização dos solos estudados, evidenciando que os problemas reportados nestas áreas são resultantes da simples elevação do lençol freático, observada nas áreas irrigadas de Argissolos

Published: June 2016

O objetivo deste estudo foi avaliar o efeito da inoculação de fungos micorrízicos arbusculares (FMA) exóticos, da acidez do solo e de fontes de fósforo no crescimento e na composição mineral de plantas de milho, Zea mays L. (Poaceae). O delineamento experimental foi em blocos ao acaso em esquema fatorial (2x2x2), correspondendo a dois níveis de V% (21 e 60%), duas fontes de P (Na2H2PO4, Ca3 (PO4)2), inoculado e não-inoculado com FMA, com cinco repetições. A inoculação proporcionou maiores concentrações de P, K e de Cu, nas folhas de milho, diminuindo os efeitos da acidez do solo em fonte solúvel de P. O solo corrigido favoreceu o crescimento radical, o aumento da concentração de Mg nas folhas, o aumento da matéria seca da parte aérea e a diminuição de Mn nas folhas. A combinação solo corrigido - P baixa solubilidade - FM autóctones demonstrou ser a mais propícia ao desenvolvimento do cultivar de milho utilizado

Published: June 2016

This article considers the problem of evaluating the effectiveness of energy-saving solutions in the aspect of the task to determine the timing of capital repairs of apartment buildings. The method of numerical simulation lifecycle of buildings is offered as a solution to this problem. It is proved that implementation of comprehensive overhauls of using energy-saving technologies increases the period of effective operation of the property as a whole, and in future - to lower operating costs. In order to enhance the safety of housing and improve the quality of housing, a new overhaul system of apartment buildings was adopted. Federal Law No. 271-FZ [1] obliges all the entities of the Russian Federation to adopt regional programs, which set deadlines of overhauls in all apartment houses. Analysis of the main program provisions showed that the overhaul term criteria do not include the results of monitoring the technical condition of buildings (physical deterioration of each component and engineering equipment), as well as the rate of the wear of building components by the time of repair and prediction of these indicators in the future during the lifecycle.

Published: June 2016

The engineering parts joining by the spot welding require acceptable properties to survive the loading conditions XE "temperature". Several studies show that the welding variables have an effect on the properties of spot nugget XE "nugget" and on the future cracking. This review summarizes the resistance spot welding process (RSW). It introduces the basic spot welding principles, experiments XE"experiments" , limitation and defects XE "defects". The new concepts and awareness were presented. The results from the series of scientific works and literature are discussed. The metal’s weldability, XE "spotweldability" strength, XE"strength" and fracture are the main topics in several structural analysis. The welding variables effect on the mechanical properties and performance XE "mechanicalproperties" of the structures is the key analysis. In general, the increasing of the heat input by adjusting the current, time, and pressure producing higher weld area in turn enhance the toughness. However, by increasing the weld area, the defects and cracking tend to appear. Hence, a desired weld size with the mechanical properties is required. The nugget fracture mode is changing from plug or button tearing to shear failure mode depending on the weld properties. The crack grows either from the internal defects or around the nugget.

Report on the composition and assemblage of minerals associated with the porphyry Cu-Mo mineralization at the Gibraltar deposit, south central British Columbia, Canada
Authors: Kobylinski C H , Hattori K , Smith S , Plouffe A
Published: June 2016

Glacial sediments commonly contain resistate heavy minerals, such as zircon, rutile and epidote. To identify the sources of these minerals and use them as a vectoring tool for mineral deposits, it is critical to understand the compositional variations and
assemblages of these minerals in mineral deposits and whether they are distinct from those in barren rocks. This paper reports the occurrence and assemblages of igneous and alteration minerals in the Gibraltar porphyry Cu deposit, southcentral British Columbia. The Gibraltar deposit is the largest
of three porphyry-Cu deposits in the region, the others being the Mount Polley mine and the Woodjam prospect. The Gibraltar deposit is hosted by the Granite Mountain batholith and has reserves of over 749 million tons at 0.249% Cu and 0.008% Mo. The batholith is mostly tonalite, with minor
variation in modal abundances of felsic and mafic minerals. Igneous minerals are plagioclase, quartz, biotite, hornblende, titanite, zircon and apatite. The mineralization is accompanied by extensive phyllic alteration in the tonalite, which produced illite, quartz, rutile, titanite, magnetite,
apatite, chlorite and epidote. Hydrothermal titanite is distinctly different from igneous titanite in crystal habits, optical properties and chemical compositions. Epidote shows a large compositional variation even within one sample from Al-rich (high clinozoisite component) to Fe-rich epidote. Some
epidote grains contain significant La and Ce (allanite component), which could be diagnostic of the porphyry mineralization. Preliminary observations suggest the presence of a potassic alteration zone forming hydrothermal biotite, but is now replaced by chlorite.

Authors: Hsu Charlie Chia-Tsong , Kwan Gigi Nga Chi , Singh Dalveer , Pratap Jit , Watkins Trevor William
Published: June 2016

Dual-energy computed tomography (DECT) simultaneously acquires images at two X-ray energy levels, at both high- and low-peak voltages (kVp). The material attenuation difference obtained from the two X-ray energies can be processed by software to analyze material decomposition and to create additional image datasets, namely, virtual noncontrast, virtual contrast also known as iodine overlay, and bone/calcium subtraction images. DECT has a vast array of clinical applications in imaging cerebrovascular diseases, which includes: (1) Identification of active extravasation of iodinated contrast in various types of intracranial hemorrhage; (2) differentiation between hemorrhagic transformation and iodine staining in acute ischemic stroke following diagnostic and/or therapeutic catheter angiography; (3) identification of culprit lesions in intra-axial hemorrhage; (4) calcium subtraction from atheromatous plaque for the assessment of plaque morphology and improved quantification of luminal stenosis; (5) bone subtraction to improve the depiction of vascular anatomy with more clarity, especially at the skull base; (6) metal artifact reduction utilizing virtual monoenergetic reconstructions for improved luminal assessment postaneurysm coiling or clipping. We discuss the physical principles of DECT and review the clinical applications of DECT for the evaluation of cerebrovascular diseases.

Published: June 2016

Purpose

The purpose of this study is to compare the health of primary caregiving African American grandmothers with diabetes with African American women with diabetes who were not primary caregivers.

Design

Using a comparative, descriptive, cross-sectional design, 34 African American primary caregiving grandmothers were compared with 34 non-caregiving women with diabetes mellitus; women aged 55–75 years were recruited for this study throughout the central Arkansas.

Methods

To measure the overall health, data on blood pressure, body mass index measurements, HbA1c levels, total cholesterol, and urine protein and creatinine levels were collected from all the participants.

Results

Statistically significant differences between the caregivers and non-caregivers groups in systolic pressure ( t = −3.42, P = 0.001) and diastolic pressure ( t = −3.790, P = 0.000) and urine protein ( W = 294.00, P = 0.000) were noted. Additionally, a clinically significant difference in HbA1c was noted between groups.

Conclusion

Differences in systolic and diastolic pressures, urine protein, and clinically significant differences in HbA1c suggest that African American primary caregiving grandmothers with diabetes mellitus may have more difficulty in maintaining their diabetic health than non-caregiving African American women.

The cannabinoids are members of a deceptively simple class of terpenophenolic secondary metabolites isolated from Cannabis sativa highlighted by (-)-Δ 9 -tetrahydrocannabinol (THC), eliciting distinct pharmacological effects mediated largely by cannabinoid receptor (CB1 or CB2) signaling. Since the initial discovery of THC and related cannabinoids, synthetic and semisynthetic classical cannabinoid analogs have been evaluated to help define receptor binding modes and structure–CB1/CB2 functional activity relationships. This perspective will examine the classical cannabinoids, with particular emphasis on the structure–activity relationship of five regions: C3 side chain, phenolic hydroxyl, aromatic A-ring, pyran B-ring, and cyclohexenyl C-ring. Cumulative structure–activity relationship studies to date have helped define the critical structural elements required for potency and selectivity toward CB1 and CB2 and, more importantly, ushered the discovery and development of contemporary nonclassical cannabinoid modulators with enhanced physicochemical and pharmacological profiles.

Še enkrat o neoliberalizmu III: psihoafektivni učinki neoliberalizma in neoliberalna subjektivnost
Authors: Krašovec Primož
Published: June 2016

Članek se ukvarja z delovanjem neoliberalizma na mikrosocialni ravni in na ravni individualne psihologije. Neoliberalna ekonomija pomeni zaostritev konkurenčnega pritiska in ocenjevanja ne le podjetij, temveč tudi posameznikov; hkrati pa neoliberalna politika pomeni depolitizacijo posameznikov, ki so le še podjetniki samih sebe. Neoliberalizem zato ne deluje kot klasične politične ideologije, ki so še predvidevale (in delovale na) politično subjektiviranega posameznika, temveč kot posebna etika vsakdanjega življenja, etika izbire, strateške racionalnosti investicij lastnega človeškega kapitala, ki je, ravno zato ker je apolitična, izrazito psihološka ter se izraža v epidemiji depresije in tesnobe na eni strani in množičnem iskanju sreče na drugi strani.
Kako mladim delavcem približati varnost in zdravje pri usposabljanju za delo
Authors: Mesarič Helena
Published: June 2016

Podatki Evropske skupnosti kažejo, da je mlada delovno aktivna populacija v starosti od 18 do 24 let zlasti zaradi pomanjkanja izkušenj in znanja o zagotavljanju varnosti in zdravja pri delu ter nezadostne usposobljenosti za varno in zdravo delo posebej ogrožena v smislu večjega tveganja poškodb pri delu in poklicnih bolezni v primerjavi s preostalo delovno populacijo. Delodajalci morajo vzpostaviti ustrezen sistem za zagotavljanje varnosti in zdravja pri delu s poudarkom na usposabljanju za varno delo dijakov in študentov, ki so na delovni praksi, ter novozaposlenih mladih oseb. Ministrstvo za delo, družino, socialne zadeve in enake možnosti vodi vrsto projektov promocije varnosti in zdravja pri delu, s katerimi si prizadeva spodbuditi kulturo varnosti med mladimi v Sloveniji. Cilj nacionalnega programa uvajanja varnosti in zdravja pri delu v vzgojo in izobraževanje je, da vzgojiteljem in učiteljem ponudi različna orodja in pripomočke, s katerimi bodo lahko mladim na zanimiv način približali varnost in zdravje pri delu.

Big data or population-based information has the potential to reduce uncertainty in medicine by informing clinicians about individual patient care. The objectives of this study were: 1) to explore the feasibility of extracting and displaying population-based information from an actual clinical population’s database records, 2) to explore specific design features for improving population display, 3) to explore perceptions of population information displays, and 4) to explore the impact of population information display on cognitive outcomes.

We used the Veteran’s Affairs (VA) database to identify similar complex patients based on a similar complex patient case. Study outcomes measures were 1) preferences for population information display 2) time looking at the population display, 3) time to read the chart, and 4) appropriateness of plans with pre-and post-presentation of population data. Finally, we redesigned the population information display based on our findings from this study.

The qualitative data analysis for preferences of population information display resulted in four themes: 1) trusting the big/population data can be an issue, 2) embedded analytics is necessary to explore patient similarities, 3) need for tools to control the view (overview, zoom and filter), and 4) different presentations of the population display can be beneficial to improve the display. We found that appropriateness of plans was at 60% for both groups (t9=-1.9; p=0.08), and overall time looking at the population information display was 2.3 minutes versus 3.6 minutes with experts processing information faster than non-experts (t8= -2.3, p=0.04).

A population database has great potential for reducing complexity and uncertainty in medicine to improve clinical care. The preferences identified for the population information display will guide future health information technology system designers for better and more intuitive display.
Contributions to the knowledge of the multitemporal spatial patterns of the Iberian Peninsula droughts from a Geographic Information Science perspective
Authors: Domingo-Marimon Cristina
Published: June 2016

Durante los últimos años el interés en el seguimiento y en los efectos de las sequías se ha incrementado a causa de las situaciones climáticas extremas acontecidas, sobre todo en la cuenca Mediterránea. Por ello, la caracterización espacio-temporal de la sequía en la Península Ibérica es fundamental para el seguimiento, previsión y gestión de sus consecuencias. Esta tesis contribuye al conocimiento de los patrones espaciales multitemporales de las sequías y sus efectos a nivel de Península desde la perspectiva de la Ciencia de la Información Geográfica. Con este objetivo, se identifica y se caracteriza la sequía a diferentes escalas espacio-temporales y se demuestra la necesidad de un nuevo marco conceptual donde la sequía forestal tenga su reconocimiento. A partir de datos climáticos y de teledetección se desarrolla una nueva base cartográfica climática (precipitación y temperatura) y de sequía (Standardized Precipitation Index- SPI and Standardized Precipitation Evapotranspiration Index- SPEI) para el periodo 1950-2012, a 8 escalas temporales diferentes, que incluye más de 14.000 mapas continuos a una resolución espacial de 100 m. Estos mapas permiten identificar la distribución espacial de las zonas más afectadas y cuantificar su intensidad y extensión temporal. Este enfoque multidimensional permite seguir la dinámica espacio-temporal de las sequías, las denominadas sequías en movimiento, y facilita la identificación de eventos simultáneos. Así mismo, se ha identificado un cambio de régimen de sequías súbito entre 1979 y 1981 que afecta al centro y el este de la Península Ibérica y que se anticipa de forma consistente a través de señales de alerta, que afecta directamente disminuyendo la fijación de carbono de los bosques mediterráneos de Pinus halepensis. El estudio se ha complementado con observaciones remotas de satélite a través de varios índices de vegetación derivados del sensor MODIS (MODerate-resolution Imaging Spectoradiometer) como posibles indicadores de parámetros del estado fisiológico de la vegetación en bosques. En resumen, la investigación llevada a cabo en esta tesis avanza en varios aspectos del estudio de la sequía tanto a nivel climático como a nivel forestal y consolida un avance en la investigación de estos fenómenos.

The aim of this study was to analyze satellite images of different spatial resolutions to interpret the morphometric behavior of six shallow lakes of the Pampas, Argentina. These are characterized by having different rainfall regimes. Morphometric response considering each location, site conditions and dry and wet extreme events is analyzed. Standardized Precipitation Index (IEP) for determination of wet, dry and normal years was used. This analysis showed that the Pampas shallow lakes do not behave in the same way to the rainfall events. Its origin, socio-economic use and rainfall patterns affect their spatiotemporal variation and morphometric.

Management of protected areas in the current context of global change requires approaches to characterize and to monitor ecosystem functioning. Remote sensing provides adequate tools for that because it provides índices that inform repeatedly and for large areas of land, about matter and energy exchanges between the biota and land surface. Considering this principle, and the continuous improvements in the availability of satellite data of higher quality and friendly use, we have developed with the Autonomous Organization of National Parks of Spain (OAPN), a monitoring system that complements other monitoring initiatives from this agency to inform about the conservation status of national parks. The system, called REMOTE, is based on the most used spectral vegetation indices on scientific literature, EVI (Enhanced Vegetation Index) and NDVI (Normalized Difference Vegetation Index), derived from the time series of satellite images of the MODIS-Terra sensor. The systems allows to progress in identification of reference conditions to understand and predict ecosystems response against environmental perturbations or management actions, and their directional changes (trends) they are experiencing. Likewise, establishment of reference conditions helps to identify anomalies that warn of sudden changes in ecosystem functioning. The system uses as ecosystem functioning indicators three attributes related to the annual carbon gains (net primary production) by the canopy, their seasonality and phenology. In addittion, Remote has been designed and programmed on open and free software allowing future modifications and improvements in an easy way. The implementation of this system aims to inform decision-makers and managers of the Network of National Parks of Spain about the health and conservation status of ecosystems.
