The recent trend towards open data and open science as well as a demand for holistic and interdisciplinary research requires platforms that allow the distribution and exchange of research data, includ...
A Data-Cleaning Tool for Building Better Prediction Models
Data-Cleaning Tool Prediction Models
2016/9/12
Big data sets are full of dirty data, and these outliers, typos and missing values can produce distorted models that lead to wrong conclusions and bad decisions, be it in health care or finance. With ...
Building a Better Backtrace: Techniques for Postmortem Program Analysis
Building Better Backtrace Techniques Postmortem Program Analysis
2016/5/25
After a program has crashed, it can be difficult to reconstruct why the failure occurred, or what actions led to the error. We propose a family of analysis techniques that use the evidence left behind...

compiler analysis and program transformations, programming and runtime environments for high performance and high throughput computing
2016/5/24
Heterogeneous computers with processors and accelerators are becoming widespread in scientific computing. However,it is difficult to program hybrid architectures and there is no commonly accepted prog...
PERCEPTUALLY GUIDED GEOMETRICAL PRIMITIVE LOCATION METHOD FOR 3D COMPLEX BUILDING SIMPLIFICATION
3D complex building Geometrical primitive location Human vision system
2016/2/29
Because of detailed geometrical components based description, 3D complex building contains the most elaborated perceptual and
comprehensive semantic information. However, since the lack of optimal si...
CONCEPTUAL REQUIREMENTS FOR THE AUTOMATIC RECONSTRUCTION OF BUILDING INFORMATION MODELS FROM UNINTERPRETED 3D MODELS
3D city models 3D graphics models, semantic modeling
2016/2/29
A multitude of new applications is quickly emerging in the field of Building Information Models (BIM). BIM models describe
buildings with respect to their spatial and especially semantic and thematic...
Computer science has become a new basic skill, essential in order to excel in an increasingly computational and data-intensive world.However, access to computer science (CS) at the K-12 levels remains...
A System and Language for Building System-Specific,Static Analyses
Extensible compilation error detection
2015/8/7
This paper presents a novel approach to bug-finding analysis and an implementation of that approach. Our goal is to find as many serious bugs as possible. To do so, we designed a flexible, easy-to-use...
The ITTC project provides tools and an infrastructure for building intrusion tolerant applications. Rather than prevent intrusions or detect them after the fact, the ITTC system ensures that the compr...
Tick Tock: Building Browser Red Pills from Timing Side Channels
Timing Side Channels Building Browser Red
2015/8/5
Red pills allow programs to detect if their execution environment is a CPU emulator or a virtual machine. They are used by digital rights management systems and by malware authors. In this paper we st...
The reconstruction of 3D city models has matured to the point where large data sets are now available. As most of the data collection
methods used are based on airborne sensors like e.g. aerial laser...
