in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
abstract pragmatics is the study of communicative action in its sociocultural context. communicative action includes not only using speech acts (such as apologizing, complaining, complimenting, and requesting), but also engaging in different types of discourse and participating in speech events of varying length and complexity. the present study aimed to investigate the assessment of pragm...
a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...

However, delivering large OO software systems in a qualitative way is a significant challenge. Scaling up requires formal precision of the semantics...
Performance Analysis According to the change of Cluster Size in Large Scale Wireless Sensor Networks
In large scale sensor networks, scalability and robustness are very important, and sensor nodes are also highly power constrained. Clustering, a method of grouping sensor nodes, can meet these requirements. Sensor networks also need to support fast delivery of important and urgent data. The purpose of this paper is to analyze the effects of cluster size on application's QoS, select proper clust...
