Finding collisions for MD4 hash algorithm using hybrid algorithm

The modification of message that meets the sufficient conditions for collision is found in the last step of differential attack proposed by Wang et all. (2005) on MD4 hash algorithm. Here we show how this attack phase, finding a collision starting from the list of sufficient conditions for the collision, can be implemented using a combination of two algorithms - evolutionary algorithm and hill climbing. Hybridization of evolutionary algorithm and hill climbing is a well-known technique for improving solutions, but it isn\u27t applied to this domain (at least by information that author has collected)

The influence of the trend of urban growth of city of Novi Sad on air quality in parks

Quality control of air in urban green areas - urban parks are rarely studied spaces, and this paper is based on research on the effects and impacts of microclimatic parameters on the detected suspended particles (PM 2.5 and PM10) with a multidisciplinary influence on public health and the quality of life of Novi Sad citizens. Excessive urbanization of urban environments and global migrations are among the most important causes of increased concentrations of air pollutants, even in urban green areas such as parks. This scientific research is part of a project focused on the effects and discrepancies of microclimatic parameters on detected concentrations of total suspended particles in the city's green parks in Novi Sad. Three urban parks of different sizes and locations with varying microclimatic influences were selected. Measurements of suspended particles (PM) were conducted at Futoški Park (FP), Dunavski Park (DP), and Limanski Park (LP) using a mobile device Aeroqual Series 500. At each location (FP, DP, LP), 10 measurements of suspended particle concentrations were conducted, with the device reporting changes in detected particle concentrations in real time. The results of the measured concentrations of suspended particles indicate variations in detected particle concentrations, with PM2.5 ranging from 4 to 36.1 μg/m3, while PM10 was detected in the range of 7 to 40.1 μg/m3. The measurement period for suspended particle pollution ranged from 12:00 to 17:30, with measured temperature fluctuations from 24.1 to 30.0°C and measured relative humidity oscillating between 39.1% and 54.4%

The article studies different perspectives of Entrepreneurial University. Firstly, it provides an overview of EU strategic documents which are highlighting the importance of entrepreneurship and entrepreneurial education. In terms of global market and economy, which is increasingly based on knowledge, economic success of any society depends on its ability to establish a comparative advantage in this domain. For competitiveness, growth and employment as well as for equality and social inclusion, it is of utmost importance to create a “knowledge triangle” of education, research and innovation. Higher education institutions must respond to the needs of the environment – people, labour market and society as a whole. Further, this article provides different views on Entrepreneurial University. After presenting various Entrepreneurial University concepts and studies it finally provides a process-based Model of Entrepreneurial University

Ekonomski efekti navodnjavanja i đubrenja u proizvodnji šećerne repe

The research of production and economic effects of irrigation to the sugarbeet and sugar growth per hectare was carried out on the carbonate humus of favourable water-physical and chemical characteristics on the location of Rimski Šančevi during the period from 2004 to 2006. The experiment was set according to the method of the Split-plot system being done in four repetitions with the usage of raindrop irrigation. During the experiment there were kept humidity soil treatments from 60 to 65% and the field water capacity (FWC) of 75-80% with a controlling variant being included. The realized profit per hectare during irrigation is 1607 $/ha and it is approximately greater of 17,6$/ha i veći je u proseku za 17,6% od proizvodnje u kontroli. Ekonomičnost pokazuje da se na jedinicu uloženog kapitala ostvauje u navodnjavanju 1, 49 jedinica prihoda ili više za 4,2% u odnosu na proizvodnju bez navodnjavanja. Rentabilnost merena iz odnosa profita i prihoda iznosi u navodnjavanju 32,8% i veća je za 6,8% od proizvodnje u kontroli. Pokazatelj produktivnosti govori da se za jednu proizvedenu tonu šećerne repe u navodnjavanju prosečno toši 1,28 časova ukupnog rada ili proizvodi šećerne repe 0,783 t/ času rada

Analysis of Socio-spatial Differentiation in Transport Mode Choice Preferences

Starting from the fact that the transport mode choice is one of those aspects of travel behaviour that, to a great extent, affects the efficiency of the transport system, this paper analyses the factors that contribute to the use of public and car transport. The goals of the analysis were to obtain insight into the preferences for using these two modes of transport in Croatia and find out to which extent the basic demographic and socioeconomic characteristics of the respondents affect the usage of car and public transport and the possibility of taking trips by these transport modes. The paper analyses the data collected by surveys on a representative national sample. The results show that in Croatia, the number of people who frequently use public transport is far fewer than the number of frequent users of passenger car transport. However, the comparison has found that the number of frequent public transport users varies significantly among certain categories of respondents. Using binary logistic regression analysis has determined that the preferences towards the frequent use of car or public transport are significantly influenced by the age of the respondents, size of the settlement, accessibility of the destinations by public transport, the number of vehicles in the household and whether the respondent is the main car user in the household.</p

Farmer innovativeness and its impact on Internet and social media adoption

In recent years, huge efforts have been made to implement ICT innovations in the agricultural sector in order to increase its competitiveness. The question that can be posed is what depends on the successful implementation of ICT innovations among farmers. Numerous scientific papers were published with the purpose of identifying factors that affect acceptance of particular innovation by users. The aim of this paper was to determine whether the farmer innovativeness influences the acceptance and the degree of using the Internet and social media by farmer. Additionally, statistically significant correlation between the demographic factors of the farmers and their innovativeness was investigated. The research was conducted using survey method. Descriptive statistics, Correlation analysis using Pearson's correlation coefficients and Chi-square test were used as statistical methods. Obtained results confirmed the initial hypotheses and based on that recommendations for the creation of a marketing strategy for introducing new ICT solutions in the field of agriculture are made
