Background: Breast cancer is the most commonly diagnosed and the leading cause of cancer death among females worldwide. The rate of breast cancer incidence among Iranian women is 17% of all cancers, it has been ranked first in Iran. This study aimed to investigate the factors affecting axillary lymph node involvement in female patients with breast cancer. Methods: A cross-sectional study was c...

By definition, web-services composition works on developing merely optimum coordination among a number of available web-services to provide a new composed web-service intended to satisfy some users requirements for which a single web service is not (good) enough. In this article, the formulation of the automatic web-services composition is proposed as several set-cover problems and an approxima...

  Introduction: Sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. In Iran, this procedure has not been addressed sufficiently. In this study, we report our experience in this area. Methods: Ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mCi of Tc-99m antimony...

Wireless sensor network is a collection of devices that monitor environmental conditions and arrange data at central location. Each device wirelessly sends the information to base station. Sensor help each other relay Routing selects path for packet transmission from source node destination node. Energy, Bandwidth Delay are demanding issues in WSN. Energy-efficient routing performed minimize en...

On an ad hoc network where each node does the routing autonomous and the starting node doesn’t know address of the target node, the owner with each node play a role as a community member, and it is expected that s/he might be know where the objective contents in the target node are existed with introduction form other members. This paper proposes the contents discovery method using “buddy list”...

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the ...
