The problem of track-to-track association (T2TA)– a prerequisite for the fusion of tracks–has been considered initially in the literature for tracks described by kinematic states [1]. More recently, it has been generalized to include additional (continuous valued) feature and (discrete valued) attribute variables which pertain to those tracks.1 These approaches allow the search for the maximum ...

In this paper, we have studied the electrical properties of the randomly distributed metallic (Co and Fe) nano/ micro wires on Silicon substrate. Deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the Si substrate. Spin coated films were irradiated with 150MeV Ni (+11) ions at a fluence of 8E7 ions/cm2, followed by UV irradiati...

in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...

background: radon is an odourless, colourless and tasteless gas and it is the first cause of lung cancer among non- smokers. the assessment of the level of radium in building materials helps in understanding the radiological implications. it has been observed that everyone has some levels of exposure to them. therefore measurement of radium and radon in the soil samples are important from publi...

background: the fatal effect of ionizing radiation on cells depends on linear energy transfer (let) level. the distribution of ionizing radiation is sparse and homogeneous for low let radiations such as x or γ, but it is dense and concentrated for high let radiation such as heavy-ions radiation. material and methods: chinese hamster ovary cells (cho-k1) were exposed to 4 gy fe-ion 2000 kev/m. ...

The geometry of a ballasted railway gradually deteriorates with trafficking, mainly as result the plastic settlement track-bed (ballast and sub-base). rate amount depend on number factors, for various reasons are difficult to predict or estimate analytically. As result, empirical equations estimating development track train passage have been proposed. A review these shows that they (i) do not r...
