In this paper are presented results of empirical survey on password quality self-assessment and several privacy issues regarding password manipulation among information systems’ users. Data was collected by questioning 627 e-mail users that were adults, Croatian national and were using e-mail system on regular basis. Comparisons among different kind of users were done regarding age, gender, technical background knowledge, university degree and experience in usage. Results of statistical analysis have shown that most of the users’ passwords are of average quality while 13,8% of all users graded their password as poor. Regarding password manipulation 53,4% of all users said they use the same passwords for most of the information systems they use. In total 20,7% of all users sometimes lend their password and 17,1% of them wrote it down for remembering. Results of this study highlighted importance of using security procedures and guidelines and need of the continuous education on security issues with constant informing and alerting of information systems’ users. This study is an example on how to evaluate different users’ security awareness in order to adjust courses on security issues and to adapt informing and alerting to different groups of information systems’ users. However, there is great need for validated universal questionnaire for this kind of surveys. © 2015, KoREMA. All rights reserved.

Encouraged by broadband development initiatives and strategies that aim at the reduction of the existing digital divide between rural and urban European areas by the year 2020, the current situation in the case study of Croatian rural broadband market is analysed, and the possibilities for further broadband Internet access implementation in rural areas are highlighted in the paper within the context of broadband ecosystem elements analysis. Furthermore, in order to address the exisiting digital divide problem, an extended techno-economic modelling process for rural broadband Internet access implementation analyses is proposed. The proposed additional part of model serves as an upgrade for the standard techno-economic models and allows a detailed analysis of the specificities of different rural areas, based on the available data. Finally, the efficiency of the proposed model’s application when choosing the best business strategies for different fixed and mobile, wired and wireless broadband access solutions in rural areas is presented. © 2016, Strojarski Facultet.

The work presented here attempts to identify a set of software project performance measures and influence factors used by software development projects so that a valid comparison of performance can be made between completed projects. The performance measures identified in this document are core measures that are identified as a part of the set of critical measures of success since they address important attributes of a software development project. For forty small and medium sized software projects the performance measures and the influence factors were measured.

In attempts to increase the production quality and to decrease the production costs in ceramic tile industry almost every phase in the production process needs to be automated. One way of decreasing the production costs is to detect the tiles with defects before the baking process (biscuit tiles). The separated tiles are returned to the input material mixture and the energy is not spent on baking the tiles with defects. In this paper methods for edge and corner defects detection of a biscuit ceramic tile are presented. Methods are implemented and tested on biscuit ceramic tiles using area scan camera and a prototype conveyor line. These methods are evaluated by the defect detection capabilities and the real-time application features. The results show that the methods could be used for real-time application and that the defect tiles detection percentage can reach the required value.

This paper presents a systematic study about the applicability of color/texture descriptors in a global localization system based on planar surface segments. Two comprehensive experiments regarding matching of planar surface segments and robot pose hypothesis evaluation were conducted. The experiments show that using color/texture descriptors to prune potential surface pairs in the initial correspondence phase and to provide additional information in the hypothesis evaluation phase of a feature-based localization scheme can result in considerable speedup of the localization process and help distinguish between geometrically similar places. An experimental benchmark which enables researchers to evaluate the performance of color and texture descriptors in the context of mobile robot localization based on planar surface segments is presented. © 2016 Elsevier B.V.
