In this article, we built a reef complex geological model, which is based on the geological characteristics and electric characteristics on the upper Jurassic Karloff-Oxford Formation of Asser Block at the Right Bank of the Amu River, and studied seismic response of carbonate formation by the wave equation forward modeling. Seismic response characteristics of reef complex in the area are the mound-shaped and lenticular reflections characteristics. Seismic wave in the edges of the reef complex often appear onlap and diffraction seismic reflection phenomenon, and there is upper bend phenomenon on the top of the reflection wave. The reflection wave on the top of the reef complex is trough weak reflection, with weak amplitude and discontinuous wave-front. The internal reflection wave in reef complex are unorganized or weakly, and there is a big difference in continuity between it and that of the surrounding rock on the amplitude, frequency and phase. Moreover, compared with formations of two wings, we found out that the thickness suggested by the reflection waves in the internal reef complex is bigger. The characteristics mentioned above are consistent with seismic section characteristics of reef complex over well. So that, we built a characteristics to recognize pattern of seismic of reef complex by using forward modeling results of a reef complex.

ISO/IEC 20000 is the first international standard for IT Service Management. Previous researches have showed that this standard needs improvements. This paper is focused on the improvement of the process model for ISO/IEC 20000 standard. The paper is based on the improvement of process model for ISO/IEC 20000 standard by using the comparison with ITIL 2011 framework and with eTOM and ISO/IEC 27000 standard. The result of the research is the new improved process model for ISO/IEC 20000 standard which can be implemented in any business environment. This is the first research which takes more than one other ITSM framework or standard for the comparison with ISO/IEC 20000 standard. The paper has a practical significance because this new model will be also implemented in BH Telecom, the leading Telecom operator in Bosnia and Herzegovina. Key-Words: ISO/IEC 20000, ITIL 2011, ISO/IEC 27000, eTOM, Establish ISMS, Assurance Service Management & Operations, Assurance Resource Management & Operations.

Ischemic optic neuropathy (ION), is one of the most well-known disease which could lead to vision loss or blindness. ION impacts the head of the optic nerve (ONH),referred to as anterior (AION), and the other parts of the optic nerve, referred to as posterior (PION).This article presents a customized image processing method based on low pass filtration and segmentation of the area around the ONH , which is the region of interest (ROI) to detect ION. The extracted RIOs features for the optic nerve were analyzed and employed by statistical analysis's such as descriptive analysis and test of hypothesis. To test the sensitivity of the proposed imaging method to discriminate images of individuals with ION from healthy ones, 76 fluorescein angiography images were analyzed. The images were classified based on participants status such as: healthy, ION over the age of 45, ION under the age of 45. The proposed method demonstrated a 95% accuracy in discriminating healthy images from those with ION, and consequently would help identify the clinical features of ION.

This paper presents a feature analysis of two electromagnetic interference test facilities. The one is an anechoic chamber and the other is a reverberation chamber. And then, this paper reviews problems of the current reverberation chamber, the stirrer. In general, a reverberation chamber uses a stirrer to generate a uniform electric field inside it. However, the stirrer is a big sized unit and has rotating parts in it, which makes problems and difficulties in maintenance. To conquest these problems, this paper suggests a diffuser which is commonly used in acoustics. To study the substitution effect of a diffuser, a diffuser and a reverberation chamber for 5.0-7.0 GHz band are designed and fabricated. And then, the real measurement of electric field intensity is done to study the electromagnetic interference characteristics in a reverberation chamber with a diffuser. With the measurement results, it is show that a diffuser satisfies the international standard requirement, which means the reverberation chamber with a diffuser can be used as an official facility for the electromagnetic interference measurement.
