A-tree: Distributed indexing of multidimensional data for cloud computing environments
(2011)Efficient querying of huge volumes of multidimensional data stored in cloud computing systems has become a necessity, due to the widespread of cloud storage facilities. With clouds getting larger and available data growing ... -
Accelerating techniques on nested decomposition
(2017)In this paper, we consider the nested decomposition method in the context of multistage stochastic problems with scenario trees where we contribute with improvements in accelerating convergence to optimum. We first propose ... -
Acetylation of tropical hardwood species from forest plantations in Costa Rica: an FTIR spectroscopic analysis
(2020)Acetylation of softwoods has been largely investigated to increase the dimensional stability and biological resistance of wood. However, the knowledge of this technology has not been applied to tropical hardwood species ... -
Afforestation of agricultural land as a measure of management and development of rural areas
(2003)The key measures for the environmental protection of agricultural land in the EEC countries, constitute accompanying measures of reformed Common Agricultural Policy. These measures concern the Reg. 2078/92/EEC about "crop ... -
Air flow and associated sensible heat exchanges in a naturally ventilated greenhouse
(1997)In order to investigate the three-dimensional nature of the air flow within the greenhouse, a three-dimensional sonic anemometer was used for the direct measurement of air and heat exchange inside the greenhouse and through ... -
Allometric biomass models for european beech and silver fir: Testing approaches to minimize the demand for site‐specific biomass observations
(2020)In this paper, site‐specific allometric biomass models were developed for European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) to estimate the aboveground biomass in Șinca virgin forest, Romania. Several ... -
The analysis of ‘Financial Resource Curse’ hypothesis for developed countries: Evidence from asymmetric effects with quantile regression
(2020)A vast body of literature either proxies natural resource abundance with total rents or focuses on the natural resource curse hypothesis. Furthermore, most empirical studies in the literature use traditional estimation ... -
Bar-HRM for Species Confirmation of Native Plants Used in Forest Restoration in Northern Thailand
(2022)Plant species confirmation is a crucial step in using native plant species for forest restoration. To enhance this, a hybrid method of DNA barcoding and high-resolution melting analysis (Bar-HRM) was investigated in this ... -
Benders decomposition with integer subproblem
(2017)The application of Benders decomposition method to a problem might result in a subproblem including integer variables. In this case, it is not able to apply the classical Benders algorithm. In this study we present a ... -
Bulk insertions into xBR+-trees
(2017)Bulk insertion refers to the process of updating an existing index by inserting a large batch of new data, treating the items of this batch as a whole and not by inserting these items one-by-one. Bulk insertion is related ... -
Bulk-loading and bulk-insertion algorithms for xBR +-trees in Solid State Drives
(2019)Spatial indexes are important in spatial databases for efficient execution of queries involving spatial constraints. The xBR +-tree is a balanced, disk-resident, Quadtree-based index for point data, which is very efficient ... -
Bulk-loading xBR+-trees
(2016)Spatial indexes are important in spatial databases for efficient execution of queries involving spatial constraints. The xBR+-tree is a balanced disk-resident quadtree-based index structure for point data, which is very ... -
Business model for developing strategies of forest cooperatives. Evidence from an emerging business environment in Greece
(2020)Forest cooperatives are essentially a form of entrepreneurship. However, they are confronted by various problems and they cannot pay enough attention to value creation. The aim of this paper is twofold: (a) the identification ... -
Calibration of a growth model for tomato seedlings (TOMSEED) based on heuristic optimisation
(2015)A mechanistic growth model for tomato seedlings cultivated in unheated beds is developed, based on modifications of existing tomato growth models. Photosynthetically active radiation at crop level, air temperature and CO2 ... -
Characterisation of moisture in scots pine (Pinus sylvestris l.) sapwood modified with maleic anhydride and sodium hypophosphite
(2021)In this study, the wood–water interactions in Scots pine sapwood modified with maleic an-hydride (MA) and sodium hypophosphite (SHP) was studied in the water-saturated state. The water in wood was studied with low field ... -
Classification of Driving Behaviour using Short-term and Long-term Summaries of Sensor Data
(2020)The classification of driving behaviour is important for monitoring driving risk and fuel efficiency, as well as for adaptive driving assistance and car insurance industry. Starting from raw measurements of acceleration ... -
Crop reflectance monitoring as a tool for water stress detection in greenhouses: A review
(2016)Multisensory platforms for remote sensing measurements offer the possibility to monitor in real-time the crop health status without affecting the crop and environmental conditions. The concept of the speaking plant approach, ... -
A deep learning approach for anthracnose infected trees classification in walnut orchards
(2021)This paper presents a novel approach for the detection of disease-infected leaves on trees with the use of deep learning. Focus of this study was to build an accurate and fast object detection system that can identify ... -
Deforestation processes in Greece: A spatial analysis by using an ordinal regression model
(2010)Forest land use changes in Greece have been the outcome of combining forces with mostly economic and institutional origin. Interactions between the major land uses have diachronically resulted in spatial patterns of great ... -
Delineation of management zones in an apple orchard: Correlations between yield and soil properties
(2011)In the present paper the yield and soil spatial variability in an apple orchard was studied. Apples were collected manually and placed in plastic bins along the tree rows. Yield per ten trees was weighted and the geographical ...
