Software having vulnerabilities may cause information loss and damages. The traditional software development process is not capable enough to minimize vulnerabilities that attackers exploit. Vulnerabilities and loopholes act as a disease in a software system, they replicate itself and they may damage the other connected systems. In order to make a secure software system or to minimize the impact of these loopholes it is required to scrutinize software architecture. The focus of the research work is to quantify security by scrutinizing software architecture and available design information. A methodology has been proposed to quantify confidentiality security attribute. As an outcome of the methodology two security metrics and a state transition model has been derived and implemented using several class diagrams. Statistical significance has been given by using other similar projects.

The paper compared the results of automatic calibration of two hydrological models based on Snyder’s and Clark’s synthetic unit hydrographs. Optimal values of model parameters were determined by the objective functions: percentage error in peak flow (PEPF), percentage error in volume (PEV), peak-weighted root mean square error (PWRMSE), sum of absolute residuals (SAR) and sum of squared residuals (SSR). The last part of the analysis was to assess the flexibility of both studied models. The research was performed in the upland watershed of Grabinka – left tributary of the Wis?oka river located in Southern Poland. The analysis revealed that the smallest differences between the maximum flow in the observed and calculated flood culmination were obtained when applying PWRMSE function. It wasalso indicated, that efficiency of Clark’s model in describing the analyzed floods was somewhat better than of Snyder\

As a result of the many floods which occurred over the years 1903-2010 in the drainage basin of the Upper Odra, several changes were observed in the meandering river channel. In 1966 and 1997 the high stages, velocities and flow rates caused the waters to break through the banks of two meanders on the Polish-Czech border in the vicinity of Chałupki (Poland) and Bohumin (Czech Republic). New distributaries were thus created. River erosion combined with the settling and sedimentation of deposits contributed to silting up of the original meanders, cutting them off and forming two oxbow lakes. In 2008 the site was acknowledged to be unique because of the presence of rare natural habitats and fauna and flora species. Consequently, it was entered into the Natura 2000 network. After the floods in 1997 and 2010 the valley of the meandering Odra underwent further morphological changes. Since that time the quality of both water and sediments has been gradually improving. All these elements make the site increasingly attractive in terms of its landscape and natural values. The river reach on the Polish-Czech border is unique not only in Poland, but also in Europe. The dynamic fluvial processes occurring in the Odra meanders area and the fact that these meanders constitute an important link between the deforested valleys of Ostrava (Czech Republic) and Racibórz (Poland) predispose the site to become a reference for similar rivers.

study of clinical biomechanic of injured instrument vertebral column is restricted to\nqualitative consideration. Recently with helping Finite Element Method studies are done. Quantitative\ninstrument evaluation injured instrument vertebral column have got new shape. At most of the\nbiomechanical studies are done on the evaluation stability of implants and vertebral column (instrument), so\nfor determining any stress distribution, in this research five pieces of posterior spinal implants system\nevaluated stress distribution,maximum von mises stress and displacement with using Finite Element Method\nand ANSYS software which including: Cotrel Dubousset Horizon, pedicular screw, made of medical\ntitanium, pedicular screw, made of medical stainless steel, Cotrel Dubousset Horizon, laminar hook,\npedicular hook, device for transvers traction, DTT hook and connecting rod , that all of them were made\nfrom medical titanium , in conditions without vertebra and in all loading conditions similar to biomechanic\nloading include: axial compression, flexion, lateral bending and axial rotation. In this research, quasi static\nsafety factor of fixation devices determined between 3 to 6, so results of this study show that maximum\nVon Mises stress, at all loading conditions happen on the neck of the pedicular screws, in the blade of the\nhook and in the middle of the rod.

Ad hoc networks provide flexible and adaptive networks with no fixed infrastructure and dynamic topology. Owe to the vulnerability nature of ad hoc network, there are lots of security threats that diminish the development of ad hoc networks. Therefore, to provide security for information of users and to preserve their privacy, it becomes mandatory to use cryptographic techniques to set up secure mobile ad hoc network. Earlier cryptographic method based on computational complexity ruins with the advent of fast computing computers. In this proposal, we proposed Secure Key Management (SKM) framework. We make use of McEliece algorithm embedded with Dispense Key designed for key generation and for the key distribution, and it is highly scalable with respect to memory. The experimental result shows that our framework provides a high-performance platform to execute key generation, key distribution scenarios. SKM framework reduces execution time of encryption and decryption by minimizing the number of keys.

Echinacea purpurea (L.) Moench, is a perennial plant, native to North America, from which there air used in therapeutic purpose the aerial parts and the roots. The aerial parts contains flavonoides, polyphenolic acid, coffee acid, volatile oil etc. The medicine prepared from this plant determines the rise of self defense system of the human body ( by mobilizing the leukocytes and extending the phagocytosis activity and inhibits virus multiplication). During 2010 – 2012 at SCDA Secuieni researches were conducted to establish the optimum doses of muck and its influence over the herba production and active principles content in Echinacea purpurea L. (Moench). The results indicated that the optimum variant was the one fertilized with 40t/ha fermented muck. In this variant the dry herba production obtained during three vegetation years were 39.14 g/ha in the second year, 72.13 g/ha in the third year and 74.02 q/ha in the fourth year. The highest coffee acid content (79.7 mg/100ml tincture) was determined in leaves from plants fertilized with 30t/ha muck and the highest content in polyphenolic acid (2.657 g clorogenic acid) was determined in flowers from plants fertilized with 40t/ha muck.
