Recently, the rapid evolution of technology has resulted in a significant increase in the volume of data generated by both users and organisations. This, in turn, has given rise to the big data phenomenon. However, traditional relational databases are ...

In recent years, memory-intensive operations are becoming dominant in efficiency of running novel neural networks. Just-in-time operator fusion on accelerating devices like GPU proves an effective method for optimizing memory-intensive operations, and ...

In many countries, governments encourage municipalities to develop open data policies and subsequently open up data. Municipal open data policies are often supply-driven and not based on residents' wishes. Municipalities lack insight into residents' ...

In this paper a novel 2‐D range free positioning method which uses visible light communications network architecture is presented. The algorithm performance for lattice and hexagonal LED lighting infrastructure deployment is obtained by computational ...

This paper presents OmniViewer, a multi-modal 3D video streaming system based on Dynamic Adaptive Streaming over HTTP (DASH) standard. OmniViewer allows users to view arbitrary side of a performer by choosing the view angle from 0° to 360°. Besides, ...

With the increasing usage of XML on information sharing over the Internet, a mechanism for defining and enforcing XML access control is demanded, such that only authorized entities can access the sets of XML data that they are allowed to. The research ...

Every software program that interacts with a user requires a user interface. Model-View-Controller (MVC) is a common design pattern to integrate a user interface with the application domain logic. MVC separates the representation of the application ...

Several efforts in research and development of technologies have been spent to publish data in open standard formats. The main project in this regard is the Linked Open Data, which goal is to create an open and semantic Web of Data, enabling processing ...

While XML has been widely adopted for information sharing over the Internet, the need for efficient XML access control naturally arise. Various XML access control enforcement mechanisms have been proposed in the research community, such as view-based ...

In the field of software technologies, the adoption of Service Oriented Architecture for IS has been accompanied by the introduction of new service component models which are well-suited to realize services. While these service components offer new ...

In the area of software architecture, in recent years, modeling design decisions is becoming more and more popular as a means to record architectural knowledge (AK) and capture the rationale of a design. Unfortunately, decision modeling is rather time-...

This work aims at treating the inference problem in XML documents that are assumed to represent potentially incomplete information. The inference problem consists in providing a control mechanism for enforcing inference-usability confinement of XML ...

A cognitive map represent concepts linked by influences. This paper introduces a taxonomic cognitive map model that allows to define a cognitive map on a taxonomy. This taxonomy is used to provide simplified views of a map to help a user to understand ...

We revisit the problem of answering tree pattern queries using views. We first show that, for queries and views that do not have nodes labeled with the wildcard *, there is an approach which does not require us to find any rewritings explicitly, yet ...

DatabaseExplorer is an open-source cross-platform software tool aimed for a database structure and data manipulation. It is written in C++ language by using a cross-platform GUI toolkit called wxWidgets. The application can be used under MSWindows and ...

Policy-based inference control of queries submitted to a logicoriented information system requires us to consider the history of queries and answers to a particular user. In most previous approaches, the control system captures the history by ...

Steering and driving tasks -- where the user controls a vehicle or other object along a path -- are common in many simulations and games. Racing video games have provided users with different views of the visual environment -- e.g., overhead, first-...

With the growing need of integration and sharing of spatial data located in different places on the network, distributed spatial database technology has become a hot research field. Meanwhile, spatial information security, especially access control, has ...

In this paper, we study the problem to compute certain answers in case when view definitions are expressed as non-recursive datalog programs with negation and queries are expressed as semi-positive non-recursive datalog programs with negation. Two ...

As systems have been integrated into networks, they are required to operate in an environment that includes heterogeneous demands and modes. The heterogeneous requirements have to be met and the heterogeneous modes have to coexist under an evolving ...
