Volume 3, Issue 1 , Winter and Spring 2021, Pages 87-94

http://dx.doi.org/10.24271/psr.17

Abstract
  This study was designed to determine the extent of contamination of water storage tanks by non-lactose fermenter Enterobacter spp, and to characterize the chlorine and antibiotic resistance status. Moreover, to find the correlation between biofilm formation and resistance to chlorine. For this ...  Read More

2. A new approach to the fuzzy c-means clustering algorithm by automatic weights and local clustering

Volume 3, Issue 1 , Winter and Spring 2021, Pages 95-101

http://dx.doi.org/10.24271/psr.18

Abstract
  Clustering is one of the essential strategies in data analysis. In classical solutions, all features are assumed to contribute equally to the data clustering. Of course, some features are more important than others in real data sets. As a result, essential features will have a more significant impact ...  Read More

3. Adaptive Load Balanced Routing in IOT Networks: A Distributed Learning Approach

Rzgar Sirwan; muzhir al-ani

Volume 3, Issue 1 , Winter and Spring 2021, Pages 102-106

http://dx.doi.org/10.24271/psr.19

Abstract
  Facilitating large-scale load-efficient Internet of things (IoT) connectivity is a vital step toward realizing the networked society. Although legacy wide-area wireless systems are heavily based on network-side coordination, such centralized methods will become infeasible in the future, by the unbalanced ...  Read More
