Reuse is as an important approach to conceptual object-oriented design. A number of reusable artifacts and methodologies to use these artifacts have been developed that require the designer to select a certain level of granularity and a certain paradigm. This makes retrieval and application of these artifacts difficult and prevents the simultaneous reuse of artifacts at different levels of gran...

The region of image compression since it is applicable to various fields of image processing. The key goal of compression is to cut back the space for storage and decrease the transmission cost and maintain the visual quality of image. This paper presents fundamental approach for analysis and evaluating the image compression techniques. This paper describes the many techniques which can be used...

The general objective of the present study was to investigate how elementary school students engage in their knowledge construction processes in computer-supported collaborative learning. We will report a longitudinal case study of a teacher’s and researchers’ effort to create classroom activities and social practices that support genuine participation in knowledge-creating inquiry. In this cur...

In this work we comprehensively categorize image quality measures, extend measures defined for gray scale images to their multispectral case, and propose novel image quality measures. They are categorized into pixel difference-based, correlation-based, edge-based, spectral-based, context-based and human visual system (HVS)-based measures. Furthermore we compare these measures statistically for ...

Introduction: Motion of the patient during myocardial perfusion SPECT could potentially results in false perfusion defects. The effect of different reconstruction methods on these artifacts is not studied. Clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. This...

achaemenid ruled over a vast territory, to which included asia minor (modern turkey), that was conquered during cyrus the great campaign to lydia. following this its cities was added to persian satrapies. the name of all the persian satrapies was not mentioned in achaemenid official texts, because achaemenid political style was in this way that the conquered areas came under the central power c...

Artifacts support evaluating new research results and help comparing them with the state of art in a field interest. Over past years, several artifacts have been introduced to self-adaptive systems. While these shown their value, it is not clear what extent on problems self-adaptation that are relevant industry. This paper provides set guidelines for aim at supporting industry-relevant selfadap...
