background: radiation-sensitive polymer gels are among the most promising three-dimensional dose verification tools and tissue-like developed to date. among the special features of this type of dosimeters, is be doped with other elements or chemicals which made them appropriate for investigating of dose enhancement with contrast agents, by high atomic number. material and methods: in this study...

Digital image processing is an ever expanding and dynamic area with applications reaching out into our daily life such as digital signature, authentication, surveillance, medicine, space exploration, automated industry inspection and many others areas. Theseapplications are involved in different processes like image enhancement, object detection, features extraction, colour imaging etc. Impleme...

This article examines how people’s beliefs about deception in text-based media (i.e., email, instant messenger) and face-to-face communication are distorted by two biases: (a) a self-other asymmetry, whereby people believe themselves to be more honest than their peers across communication contexts; and (b) a media intensification effect, whereby the perceived gap between one’s own and others’ d...

objective(s) the purpose of the present study was to use the solid dispersion (sd) technique to improve the dissolution rates of indomethacin (imc). materials and methods imc solid dispersions in pvp k30 and isomalt (galen iq 990) were prepared using the solvent evaporation technique and a hot melt method in weight ratios of 2, 10 and 30% (imc:pvp). solid dispersions and physical mixtures were ...

In previous research evidence for the effects of stress and accent on phonetic variation is based on laboratory speech. In the present paper, we report on a study of the effects of accent on the acoustic cues for stop voicing and place of articulation in the speech of four announcers from the Boston University Radio News corpus. The results show that there are significant effects of accent on V...

With data from Pantheon, we have at our disposal a sample of more than 1000 supernovae Ia covering wide range redshifts with good precision. Here, make fits to the corresponding Hubble–Lemaître diagram various cosmological models, intergalactic extinction, evolution luminosity supernovae, and redshift components due partially noncosmological factors. The are well fitted by Standard Model includ...

Text characters embedded in images and video sequences represents a rich source of information for content-based indexing and retrieval applications. However, these text characters are difficult to be detected and recognized due to their various sizes, grayscale values and complex backgrounds. This thesis investigates methods for building an efficient application system for detecting and recogn...

The goal of this contribution is to use a parametric speech synthesis system for reducing background noise and other interferences from recorded speech signals. In a first step, Hidden Markov Models of the synthesis system are trained. Two adequate training corpora consisting of text and corresponding speech files have been set up and cleared of various faults, including inaudible utterances or...
