A semiconductor device simulator PC1D is used to investigate the behavior of photosensitive polycrystalline p/i and p/i/n structures. the main physical characteristics - impurity concentrations, diffusion lengths, bulk and surface recombinations are varied in a wide range. the junction depths and thicknesses of the constituent layers are fixed. the obtained electrical characteristics for both photosensitive structures are compared. On the base on. the obtained results, optimized structures of photosensitive sensors are proposed. It is shown that the PC1D can be successfully applied for simulation of polycrystalline photosensitive structures.

In this article the inter-symbolic interference is analyzed as a disturbance. At given information flow and known pulse characteristics of the channel the received signal could be defined with precision up to additive disturbance. A mathematical model of a radio channel with frequency-dependent parameters received under inter-symbolic interference is proposed. this method for compensation of inter-symbolic interference allows evaluation of errors probability during the process of the received signal recognition for different types of the signal modulation and proposes algorithms for inter-symbolic interference compensation.

We present a novel system for performing real-time detection of diverse visual corruptions in videos, for validating the quality of graphics units in our company. the system is used for several types of content, including movies and 3D graphics, with strict constraints on low false alert rates and real-time processing of millions of video frames per day. these constraints required novel solutions involving both hardware and software, including new supervised and weakly-supervised methods we developed. Our deployed system has enabled a 20X reduction of human effort and discovering new corruptions missed by humans and existing approaches.

Using handwritten digit classification as the target application, we implement an incremental gradient descent artificial neural network on a graphics processing unit (GPU). While GPUs feature a massively parallel architecture, we find that most neural networks are relatively small and cannot fully occupy the GPU's resources. Nevertheless, enough parallelism and arithmetic density is found in the feed forward and back propagation stages of neural network training to attain a speedup of 1.63 over an optimized serial version. We also compare our matrix-vector multiplication with alternative implementations and show that ours outperforms all others in a low occupancy situation.

the cone-beam computer tomography (CT) is relatively new non-destructive testing method, used in the industry. Withthe aid of this method, the attenuation coefficient of x-ray is tested. the fact that the samples are characterized by a different density and thickness explains why the various contrasts are obtained in the end results. A digital detector detects this information, in form of grayness' ratio. In contrast to the known principle of CT in medical application, the cone-beam CT uses a volumetric beam to scan the test object and therefore obtains a series of 2D images. As a result of these scans the reconstruction is a 3-dimensional model of the tested object. During the reconstruction process, by which the artefacts are often created, an x-ray tube emits polychromatic spectrum and is called beam hardening. this process takes place because the low energetic spectrum part in the material is better absorbed than in the higher energetic one. the basic application of this method is the visualization of the inner and outer structures of electronic components, packaging and interconnection technologies. this paper will describe the basics of computer tomography, the typical beam hardening artefacts and the method to reduce their influence on the imaging quality of the measured objects. Additionally, the examples of this non-destructive testing method will also be presented.
