This introductory overview tutorial on social network analysis (SNA) demonstrates through theory and practical case studies applications to research, particularly on social media, digital interaction and behavior records. NodeXL provides an entry point for non-programmers to access the concepts and core methods of SNA and allows anyone who can make a pie chart to now build, analyze and visualiz...

I. ABSTRACT This fifth grade unit utilizes practical applications of mathematics in the “real world.” During this interactive approach to learning “math wisdom,” students will gain knowledge of number sense, computation, ratios and proportions, probabilities and statistics, and money. The students will experience various critical thinking scenarios that build upon the Core Knowledge Math Curric...

[reaction: see text] A concise stereoselective approach to the spirobicyclic imine fragment of pinnatoxins and pteriatoxins is described. The approach relies on a tandem reaction sequence involving consecutive sigmatropic rearrangements to build the quaternary chiral center at the core of the spirobicyclic ring system.

Trusted Computing is a security technology which enables the establishment of trust between multiple parties. Previous work showed that Trusted Computing technology can be used to build tickets, a core concept of Identity Management Systems. Relying solely on the Trusted Platform Module we will demonstrate how this technology can be used in the context of Kerberos for an implementation variant ...

We present efficient algorithms to build data structures and the lists needed for fast multipole methods. The algorithms are capable of being efficiently implemented on both serial, data parallel GPU and on distributed architectures. With these algorithms it is possible to map the FMM efficiently on to the GPU or distributed heterogeneous CPU-GPU systems. Further, in dynamic problems, as the di...

Unlike applets, traditional systems programs written in Java place significant demands on the Java runtime and core libraries, and their performance is often critically important. This paper describes our experiences using Java to build such a systems program, namely, a scalable web crawler. We found that our runtime, which includes a just-in-time compiler that compiles Java bytecodes to native...

The system family paradigm aims towards developing several applications out of a domain with just one underlying architecture. The foundation of this core architecture are common properties. With this prefabricated core, systems can be build faster. Modeling and development of common parts and variants have to be supported by methods and notations. This paper extends the Unified Modeling Langua...

In a surveillance system, video signals are generated by multiple cameras with or without spatially and temporally overlapping coverage. These signals need to be transmitted, processed, fused, stored, indexed, and then summarized as semantic events to allow efficient and effective querying and mining. SfinX aims to build several core components for multi-sensor fusion and mining. This paper fir...

The robot development environment (RDE) ArmarX aims at providing an infrastructure for developing a customized robot framework that allows realizing distributed robot software components. This includes communication properties, start-up and error handling, mechanisms for state implementations, interface definitions and concepts for the structured development of robot programs. In addition to th...

Despite much recent progress on accurate semantic role labeling, previous work has largely used independent classifiers, possibly combined with separate label sequence models via Viterbi decoding. This stands in stark contrast to the linguistic observation that a core argument frame is a joint structure, with strong dependencies between arguments. We show how to build a joint model of argument ...
