A Multithreaded Java Framework for Information Extraction in the Context of Enterprise Application Integration

In this paper, we present a new multithreaded framework for information extraction with Java in heterogeneous enterprise application environments, which frees the developer from having to deal with the error-prone task of low-level thread programming. The power of this framework is demonstrated by an example of extracting product prices from web sites, but the framework is useful for numerous other purposes, too. Strong points of the framework are its performance, continuous feedback, and adherence to maximum response times. The description of the framework uses UML modeling techniques for visualizing multithreading. Moreover, we tackle Java problems of stopping running threads.

Network Traffic Analysis Framework For Cyber Threat Detection

The growing sophistication of attacks and newly emerging cyber threats requires advanced cyber threat detection systems. Although there are several cyber threat detection tools in use, cyber threats and data breaches continue to rise. This research is intended to improve the cyber threat detection approach by developing a cyber threat detection framework using two complementary technologies, search engine and machine learning, combining artificial intelligence and classical technologies. In this design science research, several artifacts such as a custom search engine library, a machine learning-based engine and different algorithms have been developed to build a new cyber threat detection framework based on self-learning search and machine learning engines. Apache Lucene.Net search engine library was customized in order to function as a cyber threat detector, and Microsoft ML.NET was used to work with and train the customized search engine. This research proves that a custom search engine can function as a cyber threat detection system. Using both search and machine learning engines in the newly developed framework provides improved cyber threat detection capabilities such as self-learning and predicting attack details. When the two engines run together, the search engine is continuously trained by the machine learning engine and grow smarter to predict yet unknown threats with greater accuracy. While customizing the search engine to function as a cyber threat detector, this research also identified and proved the best algorithms for the search engine based cyber threat detection model. For example, the best scoring algorithm was found to be the Manhattan distance. The validation case study also shows that not every network traffic feature makes an equal contribution to determine the status of the traffic, and thus the variable-dimension Vector Space Model (VSM) achieves better detection accuracy than n-dimensional VSM. Although the use of different technologies and approaches improved detection results, this research is primarily focused on developing techniques rather than building a complete threat detection system. Additional components such as those that can track and investigate the impact of network traffic on the destination devices make the newly developed framework robust enough to build a comprehensive cyber threat detection appliance

SAVCBS 2004 Specification and Verification of Component-Based Systems: Workshop Proceedings

This is the proceedings of the 2004 SAVCBS workshop. The workshop is concerned with how formal (i.e., mathematical) techniques can be or should be used to establish a suitable foundation for the specification and verification of component-based systems. Component-based systems are a growing concern for the software engineering community. Specification and reasoning techniques are urgently needed to permit composition of systems from components. Component-based specification and verification is also vital for scaling advanced verification techniques such as extended static analysis and model checking to the size of real systems. The workshop considers formalization of both functional and non-functional behavior, such as performance or reliability

Finding a suitable performance testing tool

Abstract. The pursuit of finding the most suitable testing software for each project is a difficult task as there are a lot of software effective finding certain kind of problems but completely missing others in the field of stress and load testing. A silver bullet solving all problems in a cost effective and reliable way has not yet been found. This project was done as a systematic literature review to find whether there are solutions documented capable of testing everything in a cost-effective way. The document starts with an introduction of the task, originating from a real software testing company’s suggestion of finding suitable test software that can, cost effectively and reliably, fulfil the needs of the company. A history section is describing the reason of testing importance, basics of testing and what others have found in their studies of the area. The research method is described in detail followed by results describing tools found during the research divided in sections by license type. The sectioning by license type was selected for the benefit of testing companies that are interested in further developing tools found to their own interest. Findings and answered research questions were presented and discussed followed by possible implications and further research suggestions to future scholars interested in the matter. The systematic literature review found a total of 40 different tools identified during the data extraction process. One complete software system was available commercially including heavy support and help functions for the customer. A different approach linking open source and relatively inexpensive pieces of software together to achieve a composite solution was also identified. The solution included the most common and most popular individual piece of software identified by the study. All found pieces of software were listed and commented briefly mainly with information originating from the authors’ home pages

Advancing MATTERS

The goal of this project is to improve the data integration and administration center for the MATTERS Dashboard for the Massachusetts High Technology Council (MHTC), a pro-technology advocacy and lobbyist organization. Our system is comprised of two parts: the data integration pipeline manager and an administration center. Talend Open Studio is used as a core enabler for integrating data from a variety of online web sources. The Administration Center allows for future MHTC administrators to easily upload and view economy, talent, and ranking data, thus further impacting policies created in Massachusetts

Wireless Sensor Networks And Data Fusion For Structural Health Monitoring Of Aircraft

This thesis discusses an architecture and design of a sensor web to be used for structural health monitoring of an aircraft. Also presented are several prototypes of critical parts of the sensor web. The proposed sensor web will utilize sensor nodes situated throughout the structure. These nodes and one or more workstations will support agents that communicate and collaborate to monitor the health of the structure. Agents can be any internal or external autonomous entity that has direct access to affect a given system. For the purposes of this document, an agent will be defined as an autonomous software resource that has the ability to make decisions for itself based on given tasks and abilities while also collaborating with others to find a feasible answer to a given problem regarding the structural health monitoring system. Once the agents have received relevant data from nodes, they will utilize applications that perform data fusion techniques to classify events and further improve the functionality of the system for more accurate future classifications. Agents will also pass alerts up a self-configuring hierarchy of monitor agents and make them available for review by personnel. This thesis makes use of previous results from applying the Gaia methodology for analysis and design of the multiagent system
