nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
یکی از مهم ترین عوامل موثر در وقوع آتش سوزی در مناطق خشک، پوشش گیاهی و شرایط آب و هوایی منطقه می باشد. منطقه حفاظت شده باغ شادی یکی از مناطق جنگلی استان یزد بوده که بیش ترین آتش سوزی های استان در آن رخ داده است. به منظور بررسی عوامل موثر بر وقوع آتش سوزی در این منطقه از روش تحلیل سلسله مراتبی (ahp) استفاده شد و معیارهای فیزیوگرافی شامل سه زیرمعیار ارتفاع، شیب و جهت شیب، اقلیم شامل دو زیرمعیار د...
Background and Aim : Asymptomatic malaria is a great challenge in the control, elimination and eradication programs of the disease in the endemic areas. The infected individuals with asymptomatic malaria are not cured and are, consequently, a potential source for contamination of the mosquito vectors and spread of the disease in the area. Therefore, detection of asymptomatic infected people i...
Kepler’s Conjecture, recently proved by T. Hales, states that the densest packing of spheres in 3-space has spheres centered along the face-centered cubic (fcc) lattice. A lattice is a free Z-module formed by taking the span of a collection of linearly independent vectors in R over the integers. The two-dimensional analogue of Kepler’s Conjecture, proved by L. F. Toth in 1940, states that the d...
Deep compositional models of meaning acting on distributional representations of words in order to produce vectors of larger text constituents are evolving to a popular area of NLP research. We detail a compositional distributional framework based on a rich form of word embeddings that aims at facilitating the interactions between words in the context of a sentence. Embeddings and composition l...
Japanese encephalitis virus (JEV) is transmitted to humans from pigs or birds by mosquitoes. In this study, the association between urban pig keeping and mosquito vectors was analyzed. A total of 7, 419 mosquitoes were collected overnight in urban households with and without pigs in Can Tho City, Vietnam. The most prevalent vectors were Culex tritaeniorhynchus (36%), Cx. gelidus (24%), and Cx. ...
This paper presents a method for segmenting interstitium and tubules in images of kidneys' biopsies. Openings by structuring elements of increasing size, forming a granulometry, were performed on the entire image. For every pixel x and for each size of the structuring element the volume over a small window centered at x was measured (a local Granulometry). The vectors deened as the volume gradi...
