Dispatching vehicle fleets to serve flights is a key task in airport ground handling (AGH). Due the notable growth of flights, it challenging simultaneously schedule multiple types operations (services) for large number where each type operation performed by one specific fleet. To tackle this issue, we first represent scheduling as complex routing problem and formulate mixed integer linear prog...

The Polish Society for Biomaterials (PSB) and AGH University of Science and Technology (AGH) hosted the 27th Conference of the European Society for Biomaterials (ESB). The conference was held in Kraków, Poland from 30th August to 3rd September 2015 at the brand new ICE Congress Center. More than 966 participants from 44 countries attended the ESB 2015 conference. Figure 1 shows the number of at...

In existing anisotropic diffusion-based semi-supervised learning approaches, anisotropic graph Laplacian is estimated based on (potentially noisy) function evaluations. We propose to regularize the graph Laplacian estimates. We develop a framework that regularizes the Laplace-Beltrami operators on Riemannian manifolds, and discretize it to a regularizer on diffusivity operators on graphs. Isotr...

The purpose of this study is to determine the woody species diversity in Sweet chestnut tree, Hazel-tree and Italian cypress ecosystems in the Guilan forests. A lozeng 0.5 ha sample plot was selectively established on each site. In the Sweet chestnut ecosystems , 4 sites were classified, whereas 10 sites of Hazel tree and Italian cypress ecosystems were classified based on species composition. ...

An outstanding square slot element, for x-band wireless applications with asymmetric coplanar waveguide fed (CPW) is proposed. Various shapes of metallic strips are utilized as grounded stubs for providing Right Hand Circular Polarization (RHCP) functionality and wide-band properties. By adjusting the proposed stubs and hook-shaped radiator, length and positions, wider impedance band width is o...

â  background treatment of hemorrhoid disease is one of the most challenging fields in general surgery in which different methods are used to treat this condition. in this study, we compared the manometric and clinical results of three treatment methods for hemorrhoids. me t hod s a total of 150 patients with symptomatic grades ii or iii internal hemorrhoids were randomly assigned to three grou...

conclusions bosworth screw and tension band wiring are both useful procedures in patients with acj dislocation, but each should be used in the selected patients with special indications. both methods had good results during follow-up period. there was not statistically meaningful difference in the articular stability, range of motion, oss score and vast score between the two groups (p > 0.05). ...

two different methods of bayesian segmentation algorithm were used with different band combinations. sequential maximum a posteriori (smap) is a bayesian image segmentation algorithm which unlike the traditional maximum likelihood (ml) classification attempts to improve accuracy by taking contextual information into account, rather than classifying pixels separately. landsat 7 etm+ data with pa...
