light is one of the important environmental factors seriously affecting plant growth. given the availability of roots in aeroponic system, the influence of various light rays emitted towards the root zone of anthurium was studied. foliar spray of calcium nitrate in concentration of 10 mm was tried because of the high importance of calcium element in enhancement of vase life and strength of cut ...

In this research, identification and classification of cotton diseases is done. The pattern of disease is important part where some features like the colour of actual infected image are extracted from image. There are so many diseases occurred on cotton leaf so the leaf color is different for different diseases. This paper uses k-mean clustering with Discrete Wavelet Transform for efficient pla...

T h e PROSPECT leaf optical properties and SAIL canopy reflectance models were coupled and inverted using a set of 96 AVIRIS (Airborne Visible~Infrared Imaging Spectrometer) equivalent spectra gathered in afield experiment on sugar beet plots expressing a large range in leaf area index, chlorophyll concentration, and soil color. In a first attempt, the model accurately reproduced the spectral r...

seventeen iranian shallot genotypes from ashtian, arak, boroujerd, dashtearjan, doshmanziari, divandareh, khomein, khansar, sepidan, siakhdarengoon, sahne, kangavar, koohrang, koohmaresorkhi, nahavand, harsin and yasouj areas were evaluated for their morphological traits. corms were collected from the mentioned regions and planted based on a complete block design. quantitative and qualitative t...

In recent years, the parameterized complexity approach has lead to the introduction of many new algorithms and frameworks on graphs and digraphs of bounded clique-width and, equivalently, rank-width. However, despite intensive work on the subject, there still exist well-established hard problems where neither a parameterized algorithm nor a theoretical obstacle to its existence are known. Our a...
