Kopjak Jozsef János Kovacs

Publication Name: 2012 IEEE 10th Jubilee International Symposium on Intelligent Systems and Informatics Sisy 2012

Publication Date: 2012-12-12

Volume: Unknown

Issue: Unknown

Page Range: 299-304

Description:

The paper presents one implementation possibility of event driven software model of distributed or classical combination logic networks. The paper first reviews the basics of event-driven systems. Greater part of article presents the mathematical basics and architecture of event-driven combinational logic and example software implementation of the model. The paper shows the software implementation of AND and OR gate. After the introduction of basic gates of combinational logic the paper introduces the concept of the universal event-driven gate. The paper ends with software implementation of symmetrical event-driven XOR gate to create odd and even functions. © 2012 IEEE.

Page Range: 253-257

Description:

Event driven program model is very good tool to write discrete control programs based on sequential logic, but to create combinational logic based controls is more problematic. The paper presents one implementation of event driven software model of combination logic networks. The paper first reviews the basics of event-driven systems. Greater part of article presents the mathematical basic and architecture of event-driven combinational logic and one software implementation of the model. The paper ends with description of event-driven universal software gate. © 2012 IEEE.

Kopjak Jozsef János Kovacs

Publication Name: IEEE 10th Jubilee International Symposium on Applied Machine Intelligence and Informatics Sami 2012 Proceedings

Publication Date: 2012-06-29

Volume: Unknown

Issue: Unknown

Page Range: 377-382

Description:

The paper present alternative multitasking kernel algorithm used in tiny real-time embedded systems, microcontrollers. The paper first reviews the basics of realtime systems and traditional programming models used in embedded systems, like sequential programming model and traditional cooperative multitasking model. Greater part of article presents an alternative multitasking programming model, the timed cooperative multitasking. The authors take the reader through the process of kernel design based on timed cooperative multitasking model. The paper ends with demonstration of event-driven model used in timed cooperative multitasking model. © 2012 IEEE.

Description:

In present, the field of Internet of Things (IoT) is experiencing significant development, as evidenced by the everincreasing number of connected devices equipped with various sensors and controllers. These devices have become an integral part of smart homes, offering numerous benefits. Paradoxically, their growing popularity also brings an increased risk of vulnerabilities that threaten the security and privacy of users. This paper focuses on analysing common IoT devices used in smart homes to identify weaknesses and propose measures for improving their protection. This will involve evaluating security tests and providing recommendations for securing the devices and safeguarding their users. The proposed solutions and recommendations will assist users in better understanding potential threats and protecting their devices from unauthorized access and the leakage of sensitive information. This research approach contributes to enhancing the security and privacy of IoT device users in smart homes.
