the effects of sodium chloride (nacl) salinity (control; canal water with 0.4 ds m-1), 2.5 dsm-1, 5.0 ds m-1, 7.5 ds m-1 and 10.0 ds m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (rosa hybrida l.) cultivars viz. ‘kardinal’, ‘angelique’ and ‘gold medal’ were studied to achieve better management, quality product...

Watermarking embeds a secret message into a cover message. In media watermarking the secret is usually a copyright notice and the cover a digital image. Watermarking an object discourages intellectual property theft, or when such theft has occurred, allows us to prove ownership. The Software Watermarking problem can be described as follows. Embed a structure W into a program P such that: W can ...

This paper describes a set of tools for the reengineering of computer-based systems, in particular software. The toolset is based on an abstract intermediate representation (IR) which incorporates the system software architecture at five levels of granularity: program level, task level, package/object instance level, subprogram level and statement level. The toolset provides a graphical user in...

Following the growing research interests in complex networks, in recent years many researchers treated static structures of software as complex networks and revealed that most of these networks demonstrate small-world effect and follow scale-free degree distribution. Different from the perspectives adopted in these works, our previous work proposed software mirror graph to model the dynamic exe...

Software process dynamics challenge the capabilities of process centered software en gineering environments Dynamic task nets represent evolving software processes by hierarchically organized nets of tasks which are connected by control ow data ow and feedback relations Project managers operate on dynamic task nets in order to as sess the current status of a project trace its history perform im...

In this paper we present a mathematical model based on graph homomorphisms permitting the analysis and the behavioral envisioning of software based systems. We first try to explain why a qualitative approach is needed and which are the limitations and problems of quantitative analysis techniques. Follow some results of a qualitative abstraction tool and some simple application examples on telec...

Software engineers usually represent problems and solutions using graph-based notations at different levels of abstractions. These notations are often semi-formal, but the use of graph transformation techniques can support reasoning about graphs in many ways, and thus can largely enhance them. Recent work indicates many applications of graph transformation to software engineering and opens new ...

This paper presents the results of X-ray CT imaging of the microstructure of sand particles subjected to high pressure one-dimensional compression leading to particle crushing. A high resolution X-ray CT machine capable of in situ imaging was employed to capture images of the whole volume of a sand sample subjected to compressive stresses up to 79.3 MPa. Images of the whole sample obtained at d...

Software Engineering is a new discipline aimed at the improvement of the production of large, quality software systems. Interest in CASE tools has grown because of the important role they play in supporting the software development process. Studies show these complex and sophisticated tools have a positive impact on quality and productivity but they have been slow to be adopted by industry; thi...
