International Conference on Applied Mathematics & computer Science (ICAMCS)

A rising variety of platforms and software programs have leveraged repository-stored datasets and remote access in recent years. As a result, datasets are more vulnerable to malicious attacks. As a result, network security has grown in importance as a research topic. The usage of intrusion detection systems is a well-known strategy for safeguarding computer networks. This paper proposes an anomaly detection method that blends rule-based and machine-learning-based methods. In order to construct the appropriate rules, a genetic algorithm is utilized. Principal component analysis is used to extract the relevant features aimed to improve the performance. The suggested method is validated experimentally using the KDD Cup 1999 dataset, which meets the requirement of using appropriate data. The proposed method is applied to detect and analyze four types of attacks in a well-known benchmark dataset: Neptune, Ipsweep, Pod, and Teardrop, utilizing Support Vector Machine, Decision Tree, and Naive Bayes algorithms. After testing the characteristics specified in the training phase, the data is classified into attack categories and normal behavior during the machine learning phase.

The paper focuses on the problem of technical social engineering attacks that encompass the manipulation of individuals to reveal sensitive information, execute actions, or breach security systems. These exploits frequently capitalize on human psychology, trust, and a lack of vigilance to attain unauthorized entry to networks, systems, or data. In contrast to traditional social engineering tactics that center on psychological manipulation, technical social engineering attacks employ technological means and strategies to manipulate and beguile individuals. The paper presents an attempt to detect social engineering attacks. The approach utilized four machine learning algorithms (decision tree, random forest, K-nearest neighbor, and extreme gradient boosting). The analysis is centered on data collected from network hosts, which may serve as indicators of a potential social engineering attack. The empirical results demonstrated high detection accuracy. © 2023 IEEE.

The modelling of the educational processes and their operational support is a key aspect in the construction of more effective e-learning applications. Instructional models are usually described by means of an educational modelling language (EML). The EML used can be one of the available standards (e.g. IMS Learning Design), the customization of a standard to meet a specific application profile, or even a domain-specific EML specifically designed to best fit in the very particular needs of a learning scenario. In this paper we propose , a general authoring and operationalization architecture capable of dealing with all these possibilities in a highly modular and flexible way. We also outline a specific implementation of based on standard XML technologies and in the BPEL4WS workflow management language, and we describe how this implementation can be used to support IMS Learning Design.

A generative approach for user-centered, collaborative, domain-specific modeling environments

作者： Zweiho, Philip Steffen, Bernhard Programming Systems Department of Computer Science Tu Dortmund University Dortmund44227 Germany

The use of low- and no-code modeling tools is today an established way in practice to give non- programmers an opportunity to master their digital challenges independently, using the means of model- driven software development. However, the existing tools are limited to a very small number of different domains such as mobile app development, which can be attributed to the enormous demands that a user has on such a tool today. These demands exceed the mere use of a modeling environment as such and require crosscutting concerns such as: easy access, direct usability and simultaneous collaboration, which result in additional effort in the realization of such tools. Our solution is based on the idea to support and simplify the creation of new domain-specific holistic tools by generating it entirely based on a declarative specification with a domain-specific meta-tool. The meta-tool Pyro demonstrated and analyzed here focuses on graph-based graphical languages to fully generate a complete, directly executable tool starting from a meta-model in order to meet all cross-cutting requirements.

International Workshop on Recommendation systems for Software Engineering (RSSE)

作者： Georg Dotzler Ronald Veldema Michael Philippsen Computer Science Department Programming Systems Group University of Erlangen-Nuremberg Erlangen Germany

In large projects parallelization of existing programs or refactoring of source code is time consuming as well as error-prone and would benefit from tool support. However, existing automatic transformation systems are not extensively used because they either require tedious definitions of source code transformations or they lack general adaptability. In our approach, a programmer changes code inside a project, resulting in before and after source code versions. The difference (the generated transformation) is stored in a database. When presented with some arbitrary code, our tool mines the database to determine which of the generalized transformations possibly apply. Our system is different from a pure compiler based (semantics preserving) approach as we only suggest code modifications. Our contribution is a set of generalizing annotations that we have found by analyzing recurring patterns in open source projects. We show the usability of our system and the annotations by finding matches and applying generated transformations in real-world applications.

A filtered tuning method for a GPC controller

IET Irish Signals and systems Conference (ISSC 2010)

作者： M.H. Schwarz C.S. Cox J. Börcsök Department of Computer architecture and System programming Safety Computer Technology University of Kassel Germany Control Systems Centre University of Sunderland UK Department of Computer architecture and System programming University of Kassel Germany

This paper presents a new tuning method based on model parameters identified in closed-loop. For classical controllers such as PI(D) controllers a large number of simple tuning methods for various application areas exist. However, when it comes to designing a generalised predictive controller (GPC) four parameters have to be specified. To choose those parameters is not a trivial task since they are not directly related to control or regulation performance. The presented tuning method exploits model-parameters to select suitable controller parameters. Additionally, a Rhinehart filter is incorporated in the design to decrease the impact of noise, therefore, a fifth parameter has to be optimised. The proposed method has been tested in simulation and on a real system.

Personalization is becoming very important direction in semantic web search for the users that needs to find appropriate information. In this paper, a classification of web personalization is proposed and semantic web search tools are investigated. Building user interest profile is essential for personalizing. Nowadays, semantic web tools use ontologies for personalization because of their advantages. It is important to mention that most of the semantic web search tools use agent technologies for implementation. © 2022, CC BY.
