Depth extraction in stereovision applications is very timeconsuming and requires hardware acceleration in real-time context. A large number of methods have been proposed to handle this task. Each method answers more or less to real-time constraints, depending on the applicative context and user’s needs. Thus, flexibility is a strong requirement for a generic hardware acceleration solution, part...

A problem of optimal information acquisition for its use in general decision making problems is considered. This motivates the need for developing quantitative measures of information sources' capabilities for supplying accurate information depending on the particular content of the latter. A companion article developed the notion of a question difficulty functional for questions concerning inp...

light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...

the accuracy and effectiveness of precision agriculture is highly depending on accuracy and time analysis of the soil moisture conditions. monitoring of the soil water status is a proper method for optimizing the agricultural irrigation. automation irrigation, based on soil moisture measurement by smart sensors has the potential to provide maximum water use efficiency by maintaining soil moistu...

a field study was undertaken with four farming systems (fs) such as; grasses and fodders, agro-forestry, agriculture (new farming systems) and shifting cultivation (old practice), to investigate the effect of land use on the soil properties, erosion and crop productivity on a loamy acidic alfisol. besides crops, the livestock were also kept and their dropping were incorporated in the respective...

We present an efficient answer enumeration algorithm for an extension of Conditional XPath with variables, which is a first-order complete query language for unranked trees of bounded depth. Our algorithm requires constant delay and linear preprocessing time for fixed queries, while depending linearly on the size of the query. It is based on a new enumeration algorithm for disjunctions of acycl...

We propose a new imaging method that achieves an ultrashallow depth of field (DoF) to clearly visualize a particular depth in a 3-D scene. The key optical device consists of a pair of faced paraboloidal mirrors with holes around their vertexes. In the device, a lens-less image sensor is set at one side of their holes and an object is set at the opposite side. The characteristic of the device is...

A field experiment was conducted to evaluate the yield and chemical composition of triticalegrain in different crop rotation and tillage systems. The first experimental factor was thecropping system – a) crop rotation and b) monoculture and the second factor was the tillagesystem – 1) conventional (CT), 2) reduced (RT) and 3) no-tillage (NT). The spring triticale yieldwas found to be 15.4% high...

This paper presents a new islanding detection method based on the difference of the power transfer angle between the distributed generation and local load. After islanding, current id and iq will be changed by adding the variation to d_q transformation block of current. This makes voltage and frequency disturbance and therefore islanding is recognized. Active islanding detection method usually ...
