An Optimization of Command History Search

A command that a user issues at the comm and prompt is a string encoded with certain character encoding. This charact er string can be stored into an appro- priate data structure in order to be documented or reused. Additional function- ality of the command line to store entered commands, along with ability to list, edit and re-execute previously entered commands, is called command history. The paper suggests an optimization of command history search based on pro- posed grammar of the command language

Enhancing the Usefulness of Blockchain Technology in Finance Sector

Blockchain technology has become widely popular with the appearance of cryptocurrencies that use the decentralized nature of blockchain in order to exchange funds between their users. In order to verify various needed details during an exchange, consensus mechanisms are used which solve simple but exhaustive calculations. Such operations fulfil their primary goal of verifying, but are a common target of public disapproval due to massive energy consumption and lack of usefulness. This work discusses different approaches and consensus mechanisms with a more useful secondary function, especially focusing on NP-complete problems as mediators in solving complex and resource-heavy problems. A new way of approaching these problems can benefit many areas, like science, healthcare, government and finance, optimizing the current infrastructure and business processes like markets, transactions, insurances, payments and supply chains, or creating more secure, reliable and efficient environment.

Optimizing the Resource Consumption of Blockchain Technology in Business Systems

Background: Blockchain technology has gained a great public interest due to the appearance of cryptocurrencies, a digital asset used for exchanging funds. Although blockchain calculations offer the benefits of security and reduced costs, blockchain is still strongly criticised for its lack of usefulness and resource-heavy consumption. Objectives: The aim of this research is to provide different insights into blockchain technology and to propose NP-complete problems as a suitable alternative to the current consensus algorithm. Methods/approach: This research discusses the current state of proposed alternatives, projects such as distributed volunteering for scientific purposes and different consensus algorithms within cryptocurrencies but focusing on incorporating NP-complete problems as a secondary, more useful option. Results: Using the properties of NP-complete problems, it is possible to solve various problems in different areas, such as science, biology, medicine and finance, but also to improve business processes, optimize markets, payments and supply chains while decreasing environmental costs. Conclusions: This paper shows that the alternative mechanisms are being developed and used to substitute an existing Blockchain algorithm with a more efficient one. It also suggests further investigation in this area because the alternatives greatly improve blockchain’s usability and efficiency

Analysis of studies learning outcomes according to Bloom's taxonomy

The paper analyses learning outcomes of undergraduate and graduate studies of Faculty of humanities and social sciences, University of Zagreb, and correlates them with the categories of Bloom’s taxonomy. By observing the representation of categories in different study programs, the paper analyses the similarities and differences between undergraduate and graduate studies, as well as between single and double major studies

Analiza odnos između ishoda učenja studijskih programa i predmeta

This paper analyzes the learning outcomes of study programs and courses at the Faculty of Humanities and Social Sciences, University of Zagreb, and associates them with levels of Bloom\u27s taxonomy in order to determine their relationships. The analysis showed statistically significant differences in the levels of learning outcomes between studies and their courses. The outcomes of study programs place more emphasis on higher levels of cognitive, affective and psychomotor domains. It was determined that there is a slight difference between the courses at the undergraduate and graduate levels of study, which is in accordance with expectations as the learning outcomes at the undergraduate level include lower levels of cognitive and affective domains. The analysis of compulsory and elective courses showed that elective courses place more emphasis on the cognitive domain, whereas compulsory courses place more emphasis on the affective domain.U radu se analiziraju ishodi učenja studijskih programa i predmeta na Filozofskom fakultetu Sveučilišta u Zagrebu te povezuju s razinama Bloomove taksonomije, kako bi se utvrdili njihovi međusobni odnosi. Analiza je pokazala da postoji statistički značajna razlika u razinama ishoda učenja između studija i predmeta koji se na njima izvode. Kod ishoda studija izraženije su više razine kognitivne, afektivne i psihomotoričke domene. Također je utvrđena razlika između predmeta na preddiplomskoj i diplomskoj razini studija, koja je u skladu s očekivanjima jer ishodi učenja na preddiplomskoj razini studija imaju niže razine kognitivne i afektivne domene. Analiza obaveznih i izbornih predmeta pokazala je da je kod izbornih predmeta izraženija kognitivna domena, a da je kod obaveznih predmeta izraženija afektivna domena
