Recently a great deal of research into construction IT has been completed, and this is ongoing to improve efficiency and quality in the construction sector. The new innovation of 3D laser scanning is aimed at being used to improve the efficiency and quality of construction projects, such as maintenance of buildings or group of buildings that are going to be renovated for new services. The 3D la...

This chapter introduces readers to the term reverse engineering RE, and to the. Of obtaining a geometric CAD model from 3-D points acquired by scanning.Reverse engineering RE has many meanings to many different people. Automation of forward engineering through CAD and CAM technologies.exactly is reverse engineering particularly in the context of CAD CAM and how this can. One should know what is...

The most known definition of reverse engineering was given by Chikofsky and Cross (1990): “the process of analyzing a subject system to (i) identify the system’s components and their interrelationships and (ii) create representations of the system in another form or at a higher-level of abstraction”. Reverse engineering is the process of discovering and understanding software artifacts or syste...

Reverse engineering transforms a final user interface into a logical representation that is manipulable enough to allow forward engineering to port a UI from one computing platform to another with maximum flexibility, minimal effort.

The maintenance, reengineering, and evolution of object-oriented software systems has become a vital matter in today’s software industry. Although most systems start off in a clean and well-designed state, with time they tend to gradually decay in quality, unless the systems are reengineered and adapted to the evolving requirements. However, before such legacy software systems can be reengineer...

JTAG’s IEEE 1149.1 standard is a well-known method to access on-chip scan chains for testmode functionality. But a large part of the accessible test-modes are usually not documented. It will be shown that often these testmodes can be reverse-engineered by looking at the JTAG inputs and outputs. Undocumented test-modes can be pretty powerful tools in gaining “back door” access to a system.

Database reverse engineering consists of recovering the abstract descriptions of files and databases of legacy information systems. A legacy information system can be defined as a “data-intensive application, such as [a] business system based on hundreds or thousands of data files (or tables), that significantly resists modifications and changes” (Brodie & Stonebraker, 1995). The objective of d...

Program understanding can be enhanced using reverse engineering technologies. The understanding process is heavily dependent on both individuals and their speci c cognitive abilities, and on the set of facilities provided by the program understanding environment. Unfortunately, most reverse engineering tools provide a xed palette of extraction, selection, and organization techniques. This paper...

The Prefix table of a string reports for each position the maximal length of its prefixes starting here. The Prefix table and its dual Suffix table are basic tools used in the design of the most efficient string-matching and pattern extraction algorithms. These tables can be computed in linear time independently of the alphabet size. We give an algorithmic characterisation of a Prefix table (it...

As a software system evolves, new features are added and obsolete are removed, the design artifacts gradually diverge from its original design. Many approaches for design recovery or reverse engineering has been suggested, most with some type of support tool. Since a project's time constraints may prohibit use of sophisticated techniques and/or tools due to the learning curves associated with t...
