Visualising software as a particle system

Visualising software as a particle system

Software visualisation is broadly concerned with the chal- lenge of representing software systems, which are notoriously intangible [1], in graphical terms that provide insight to a developer. A plethora of techniques have been developed [2], which can visualise various facets of a software system (e.g. metrics, or code clones) at different levels of abstraction (from individual lines up to architectural components). To facilitate comprehension to the user, many techniques adopt metaphors, such as cities [3], Minecraft worlds [4], or solar systems [5]. Existing approaches are ultimately restricted in terms of the range of dimensions by which they visualize software entities and their interrelationships. Entities are projected to Cartesian coordinates (x, y in 2D or x, y, z in 3D), and their attributes tend to be visualised in terms of space (e.g. the height of a building or volume of a cell in a Tree map), or colour (e.g. using a colour-scale from green to red to represent complexity). Relationships between entities are commonly visualised simply in terms of connecting lines or in terms of their relative proximity (sharing a neighbourhood in a city) – a feature that can lead to misinterpretation if two objects happen to be close to each other without a corresponding relationship. In this paper we introduce PhysViz - a software visualisation system that is built with a Computer Games framework, and takes advantage of several games technologies. PhysViz is based on the idea of attributing physical properties to software entities and relationships, thus increasing the dimensions in

Prediction of the Software Security Defects Based on the Complex Network

Prediction of the Software Security Defects Based on the Complex Network

Table 3 shows the defect evaluation of JEdit5.2.0 including the name, the KNR value, the ranking of the KNR value of the defect class and the evaluation. It is found that the KNR algorithm can evaluate the most of the defects. Besides, the accuracy of 72.7% illustrates that KNR algorithm is accurate to evaluate the software system. For example, org.gjt.sp.jedit.Buffer class operates when the files are opened in the memory. Form the complex network, this node can be referenced by many other nodes. Therefore, this class is important. In fact, the common functions such as opening files, editing files are related to this class. In addition, KNR algorithm also shows the importance of this class.

Software Development for a Pediatric Gait Trainer: From LabVIEW VI to Arduino Sketch

Software Development for a Pediatric Gait Trainer: From LabVIEW VI to Arduino Sketch

Software features of the prototyped pediatric gait trainer can be classified into three groups including I/O interface, data management and GUI. Due to size, weight, and power supply constraints, the software system have to be realized on the integration of an embedded board and a computer. Arduino platform has been selected for the embedded board due to its advantages on simplified I/O programming and cost. LabVIEW platform has been selected for the development of GUI part due to its advantages on data acquisition, signal processing features, and user interface development. The combination of LabVIEW/Arduino platforms was recognized by several biomedical research projects such as heart rate variability [3], biosignal acquisition and processing [4], and medical device prototyping [5].

Software Engineering (9th Edition) pdf

Software Engineering (9th Edition) pdf

Historically, there has always been a split between the process of software devel- opment and the process of software evolution (software maintenance). People think of software development as a creative activity in which a software system is devel- oped from an initial concept through to a working system. However, they sometimes think of software maintenance as dull and uninteresting. Although the costs of main- tenance are often several times the initial development costs, maintenance processes are sometimes considered to be less challenging than original software development. This distinction between development and maintenance is increasingly irrelevant. Hardly any software systems are completely new systems and it makes much more sense to see development and maintenance as a continuum. Rather than two separate processes, it is more realistic to think of software engineering as an evolutionary process (Figure 2.8) where software is continually changed over its lifetime in response to changing requirements and customer needs.

Lalji Prasad,Aditi Nagar[1] has defined a work on the analysis of software system for different structural and object oriented metrices. This metric based component estimation along with relationship analysis is performed under the procedure based analysis. Author discussed the metrics such as LOC, cyclomatic complexity, cohesion and coupling metrics. Author defined the analysis under the class level analysis so that the software product error detection and correction can be performed over the system. The estimation of software system under the operational measures is also performed to analyze the software quality. The operational features of the project and product is also discussed along with coupling analysis so that the estimation of software related metrices will be obtained. The paper has also discussed the software coupling measurement under the structural analysis. Zeeshan Ali Rana[2] has defined an estimation on software products to analyze the software system under defect analysis for object oriented software system. Author defined the work to perform the defect prediction in the software system and analyze the software system

Application of DESA Design Method in Object-Oriented Software Systems

Application of DESA Design Method in Object-Oriented Software Systems

A software system is inherently complex due to many dependencies between the various components that constitute the software. The dependencies between components impede maintenance, modification, and extension, which are constantly required in software systems. To minimize these dependencies, object-oriented design, which is a prevalent software design method, can be employed [1]. C++ and Java are programming languages that conform to this method, and have the potential to increase the modularity of software systems. Modularity is defined as a particular design structure, in which parameters and tasks are interdependent within units (modules) and independent across them [2].

Design of Intelligent Brake Operation Control System Based on S3C2440

Design of Intelligent Brake Operation Control System Based on S3C2440

There are three working modes of coal mine electrical equipment, namely, operation mode, standby mode and maintenance mode. When electrical equipment changes from one state to another, it is called switching. "Coal Mine Safety Regulations" stipulates that " [1] the mine should have two-circuit power supply lines, and the two power sources should come from different regions. When working normally, the mine power supply should be operated separately", which improves the reliability and safety of coal mine power consumption, but also brings some problems to the normal switching operation, such as the very complex switching process, affecting the normal production of the mine, etc. At present, the domestic switching operation is mainly to implement the operation ticket system and work guardianship system, that is, one-person operation, one-person supervision and one-person record operation mode. Such a simple switching operation requires more than a dozen pages of work tickets, and is operated by manual site, which is inefficient and has hidden dangers for the safety of operators. Based on this, an embedded intelligent switching operation control system is proposed in this paper. Frequency is measured by FFT windowed interpolation algorithm and phase is measured by fast Fourier transform algorithm. Then, according to the condition of switching, whether switching is needed or not is judged. If switching is satisfied, the processor controls the corresponding actuator action to realize switching.

Design of Mobile Robot Based on Cartographer SLAM Algorithm

In this paper, the Jetson TX1 embedded platform of Nvidia Corporation is chosen as the main control board [7]. The data collected by lidar is sent to SLAM system through Ethernet interface. SLAM system runs on Nvidia TX1 board. The bottom control module upload the motion state and pose information of the robot to the main control board. The path planning system transfers the calculated robot speed to the chassis drive system through the bottom control module. Thus, the control of mobile robot platform is realized. At the same time, the Cartographer algorithm running on SLAM system sends incremental maps and robot pose to remote industrial computer via WIFI or Ethernet for real-time display. The overall scheme of the hardware is shown in Fig. 2.
