This paper proposes a dealer-free threshold changeable construction for secret sharing schemes. In practice, the adversary’s ability might be enhanced over time, for instance by compromising more players. This problem can be resolved only by increasing the threshold. In the literature, there exist some techniques to address this issue. These solutions either have a large storage requirement or ...

Software clones – similar program structures repeated in variant forms – increase the risk of update anomalies, blow up the program size and complexity, possibly contributing to high maintenance costs. Yet, programs are often polluted by clones. In this paper, we present a case study of cloning in the Java Buffer library, JDK 1.5. We found that at least 68% of code in the Buffer library was con...

objective: in the colophon of every manuscript there is a date which indicates of the time when it has been written. sometimes these colophon dates change into another date through a slight manipulation. sometimes some dates have the potential of changing into another date, either because of passage of time or due to the scribe’s method of writing. this issue creates a problem for cataloguers, ...

Code clone detection is an important area of research as reusability is a key factor in software evolution. Duplicate code degrades the design and structure of software and software qualities like readability, changeability, maintainability. Code clone increases the maintenance cost as incorrect changes in copied code may lead to more errors. In this paper we address structural code similarity ...

The trends in expansion of electric power systems and changes in the conditions of their operation have led to complicate power system operation, increased its changeability and unpredictability that call for prompter and more adequate response of controls systems. This paper presents the hybrid model for the short-term prediction the parameters of expected operating conditions based on joint u...

The paper provides empirical insight on how changeable and reconfigurable manufacturing system concepts can be developed to meet requirements in companies, as well the related organizational technical challenges. findings reveal that there are still strong barriers towards wider implementation of reconfigurability a paradigm shift industry is required, e.g., terms managing stepwise investments,...
