Design and Implementation of a General Purpose 2D CAD System

Tunhua Wu, Qinqin Shen, Changle Zhou, Ping Wang
2012 Journal of Computers  
Key technologies for realizing the system were introduced. The methods for forming shape container, manipulating shape container and constructing graph template library were described in detail.  ...  The Redo and Undo functions were realized by serializing canvas status to temporary files. And all of the canvas statuses were managed by undo-stack and redo-stack.  ...  Each shape has serialization method for storing its important properties to archive or loading its important properties from archive. Figure 5 . Method for serializing shape container.  ...

On the convergence properties of the Hopfield model

J. Bruck
1990 Proceedings of the IEEE  
The main contribution is showing that the known convergence properties of the Hopfield model can be reduced to a very simple case, for which we have an elementary proof.  ...  We review the three known results and prove that the fully parallel mode of operation is a special case of the serial mode of operation, for which we present an elementary proof.  ...  In Section Ill it is shown that the two properties of convergence in a fully parallel mode are special cases of the convergence in a serial mode for which we have an elementary proof.  ...

Unparsing RDF/XML

Jeremy J. Carroll
2002 Proceedings of the eleventh international conference on World Wide Web - WWW '02  
There are very many different serializations of the same abstract RDF graph, most of these being decidedly nonoptimal for the human reader.  ...  Since not all graphs can be serialized in RDF/XML without giving identifiers to some blank nodes, it has to be acceptable (if undesirable) for the RDF/XML serializer to do this.  ...

Directed Graph Minors and Serial-Parallel Width

Argyrios Deligkas, Reshef Meir, Michael Wagner
2018 International Symposium on Mathematical Foundations of Computer Science  
For the class of 2-terminal directed acyclic graphs (TDAGs) our two definitions coincide, and the class is closed under both operations.  ...  Our characterization implies that a TDAG has serial-parallel width of 1 if and only if it is a directed series-parallel graph.  ...  For an undirected graph H , every h-embedding operation maintains various properties like being a 2-terminal graph.  ...

On Partial Encryption of RDF-Graphs [chapter]

Mark Giereth
2005 Lecture Notes in Computer Science  
In this paper a method for Partial RDF Encryption (PRE) is proposed in which sensitive data in an RDF-graph is encrypted for a set of recipients while all non-sensitive data remain publicly readable.  ...  The proposed method allows for fine-grained encryption of arbitrary subjects, predicates, objects and subgraphs of an RDF-graph. An XML vocabulary for specifying encryption policies is introduced.  ...  For example when the range of a property only contains few values.  ...

Bridging Property Graphs and RDF for IoT Information Management

Abdullah Abbas, Gilles Privat
2018 International Semantic Web Conference  
We propose to give property graphs a formal semantic grounding based on RDF/RDFS/OWL, with blank nodes reification, geared to JSON-LD serialization.  ...  Property graphs" have come to be widely used as the common meta-model of most graph databases.  ...  This work is also studied within "Thing'in" project for management of IoT data at Orange Labs in France.  ...

A generalized convergence theorem for neural networks

J. Bruck, J.W. Goodman
1988 IEEE Transactions on Information Theory  
This property is the basis for the potential applications of the model, such as associative memory devices and combinatorial optimization.  ...  An important property of the model is that it always converges to a stable state when operating in a serial mode and to a cycle of length at most 2 when operating in a fully parallel mode.  ...  For the sake of completeness, the proof for the case of a serial mode of operation follows. serial mode i,n N .  ...

Yevgeny Gryaznov, Pavel Rusakov
2015 Applied Computer Systems  
Such tools are RDF syntaxes – concrete text or binary formats, which prescribe rules for RDF data serialization.  ...  Text-based RDF syntaxes can be developed on the existing format basis (XML, JSON) or can be an RDF-specific – designed from scratch to serve the only purpose – to serialize RDF graphs.  ...  Graph identifiers and multiple graph serialization in a single file. 4.

Graph theory roots of spatial operators for kinematics and dynamics

Abhinandan Jain
2010 2010 IEEE International Conference on Robotics and Automation  
We show that spatial kernel operators are instances of block weighted adjacency matrices for the underlying multibody topology graphs, and that spatial propagation operators are 1-resolvents of these matrices  ...  These techniques have been shown to apply broadly to systems ranging from serial, tree, to closed topology systems, as well as to systems with rigid and flexible links/joints.  ...  The key properties of the spatial operators are inherited from the properties of BWA matrices for the underlying graphs.  ...
