Cyclic Redundancy Check (CRC) is a well known error detection scheme used to detect corruption of digital content in digital networks and storage devices. Since it is a compute-intensive process which adversely affects performance, hardware acceleration using FPGAs has been tried and satisfactory performance has been achieved. However, recent extended usage of networks and storage systems require various correction capabilities for various CRC standards. Traditional hardware designs based on the LFSR (Linear Feedback Shift Register) tend to have fixed structure without such flexibility. Here, fully-adaptable CRC accelerator based on a table-based algorithm is proposed. The table-based algorithm is a flexible method commonly used in software implementations. It has been rarely implemented with the hardware, since it is believed that the operational speed is not enough. However, by using pipelined structure and efficient use of memory modules in FPGAs, it appeared that the table-based fixed CRC accelerators achieved better performance than traditional implementation. Based on the implementation, fully-adaptable CRC accelerator which eliminate the need for many non-adaptable CRC implementations is proposed. The accelerator has ability to process arbitrary number of input data and generates CRC for any known CRC standard, up to 65 bits of generator polynomial, during run-time. Further, we modify Table generation algorithm in order to decrease its space complexity from O(nm) to O(n). On Xilinx Virtex 6 LX550T board, the fully-adaptable accelerators occupy between 1 to 2% area to produce maximum of 289.8 Gbps at 283.1 MHz if BRAM is deployed, or between 1.6 14% of area for 418 Gbps at 408.9 MHz if tables are implemented in logic. Proposed architecture enables further expansion of throughput by increasing a number of input bits M processed at a time. key words: reconfigurable computing, FPGAs, cyclic redundancy checks, adaptability, accelerators

The crisis of economy of Bosnia and Herzegovina is a perennial. For nearly a decade, the economy of B&H had been buffeted by global crisis after transitional crisis which has exacerbated some latent trends and initiated new ones. Its causes have been the external and internal, and it would exist without the global financial crisis. This paper aims to analyze economy of Bosnia and Herzegovina (B&H) and gives a critical overview of ongoing economic crisis in B&H by examining by foreign direct investments flows, trade performance indicators and remittances from abroad.Structure of the paper is given as follows: Section 2 deals with new economic trends and new developments in the countries of Western Balkans from the moment of their independence.Section 3 discusses the recent developments in economy of B&H and also it describes the main specific features of the overall trade performance indicators of Bosnia and Herzegovina for a last decade.Our findings show that the debt crisis in European Union-27 has indeed affected the countries of B&H to a particular degree through the downslide in the goods trade, unemployment is rising and purchasing power of food consumers is declining, which beside economic causes social and political problems.

Inkluzija predstavlja ogroman zadatak koji se stavlja kako pred učitelje, tako i pred nastavnike. Od savremene škole se očekuje da pruži jednake uslove za svu djecu. Inkluzija kao proces obrazovanja pokušava da stavi djecu sa poteškoća u „normalan“ razred i da se svoj djeci pruži ista šansa i prilika. Inkluzivno obrazovanje od nastavnika, odnosno učitelja, traži da prilagode svoje stavove, da radi, organizuje, da bude racionalan da bi ostvario više, da bude istraživač, programer i da ima razne druge uloge kako bi na što bolji način ostvario cilj inkluzivnog obrazovanja, tj. da pruži iste uslove svoj djeci u nastavnom procesu. Upravo u ovom radu će se predstaviti kakvu ulogu ima učitelj u inkluzivnom obrazovanju i koje sve izazove donosi inkluzivno obrazovanje za svakog učitelja, odnosno nastavnika.

Abstract Objective We present a unique case of a midline xanthoma of the occipital bone exhibiting atypical imaging characteristics with preserved bone cortex that has not previously been described. Participant This man presented with refractory headaches and suboccipital pain and a mass within the diploe of the occipital bone but with preserved inner and outer cortex of the bone. Magnetic resonance imaging showed a midline, enhancing, and marrow-replacing process in the occipital bone measuring 1.5 cm in anteroposterior (AP) diameter, resulting in mild indentation of the dorsal aspect of the cerebellar vermis. Results The patient underwent a suboccipital craniectomy. Tumor resection was from the foramen magnum to the inion and laterally until normal bone was encountered. The xanthoma was yellowish and bled a moderate amount upon resection. Conclusion An isolated cranial xanthoma with preserved inner and outer bone cortex involving the occipital bone and of midline location has yet to be described. The differential diagnosis of osteoexpansile skull lesion with preserved bone cortex should now include xanthoma. Given the broad spectrum of imaging characteristics exhibited by this unusual diagnosis, surgical intervention is indicated from a diagnostic as well as a therapeutic standpoint.

UDK 630*38:551.311.21          625.711.84:551.311.21 Tractor roads are often, due to un-implementation of appropriate rehabilitation measures, exposed to erosion processes of various intensity. These processes can be particularly expressed upon completion of forest harvesting works if natural conditions also have such character which favors intensification of erosion process. Intensification of erosion processes on tractor roads in post-exploitation period most often occur in cases when surface water appears on ruts. More intensive coverage occurs in cases when tree crowns do not cover tractor roads, i.e. if larger opening (of forest crop) is in close vicinity of tractor road, which enables larger presence of light and more intensive vegetation growth. This document applies erosion process intensity degree method and assessment of degree of coverage or coverage by litter. For assessment we used a scale from 1 to 5 (REBULA, 1991). Erosion intensity degree on observed locations goes from 1,86 to 3,73. Coverage of tractor roads by grass vegetation or coverage by litter is in range from 4,91 to 1,86.

UDK 582.475:581.4(497.6 Olovo) The research has been carried out in a formal experiment with silver fir near Očevje-Olovo, with nine provenances originating from natural BiH population of 22 years of age. The research observed following provenances: communities from the area of Bugojno, Bosanski Petrovac, Olovo-Palež, Olovo-Klis, Pale, Konjic, Fojnica, Sokolac, and Prozor. The analysis of diameter on the root collar found that there are statistically significant differences among the provenances. It was also found that the biggest diameter on the root collar was on the provenances of Fojnica, with 75.6 mm, whereas the smallest was on the provenances of Olovo-Klis, with 65.2 mm. In terms of breast height diameter, some statistically significant differences were also found, so that the biggest diameter was on the provenance of Fojnica, with 47.0 mm, whereas the smallest value of this feature was on the provenance of Pale, with 41.6 mm. The analysis of the height of different provenances for the testing period, 1999 – 2005 (7 years), suggested statistically significant differences among the provenances. The biggest value was on the provenance of Bosanski Petrovac, with 407 cm, whereas the smallest height was on the provenance of Olovo-Klis, with 364 cm. The results obtained during this research provide valuable information, which can be used as indicators for successful differentiation of silver fir.

UDK 630*56:630*11(497.6)          631.442.2:630*56(497.6) Research results of the stand volume increment changes in mixed forests of beech, fir and spruce on limestone and dolomite in Federation of Bosnia and Herzegovina (FB&H), is presented in this work. Impact of different factors to volume increment value was investigated: habitat quality, values - indicators of structural characteristics particular forest stands, and orographic characteristics if the terrain. Impact of climate differences was investigated trough position of the forests stands in particular ecological-vegetation regions in B&H. Research was done on example of 799 forest stands, trough complex methods of multiple regression analyses, and variance analyses (ANOVA), The results shows that volume increment of the forest stands, besides taxation values: basal area, relative share species in volume, average diameter of the trees, medium height of the trees 50 cm in diameter, significantly depend of the altitude and belonging to particular ecological-vegetation regions in B&H. The result of the analyses is complex model for forest stand volume increment assessment. It was concluded that volume increment of these forest is higher about 1 m3/ha, now than 50 years ago, when very similar investigation was done in the same forests.
