Abstract: | CoNiP nanowire arrays were fabricated by electrodeposition method into polycarbonate (PC) templates at different pH values. It is obvious that the crystal structure of the CoNiP nanowires depends on the pH values of electrolyte. The XRD results show that crystal structure of the CoNiP nanowires is hcp structure and the intensity of the hcp (002) increased enhances as solution pH=3.5. Magnetic measurements indicate that CoNiP nanowires show a transition from soft to hard magnetic properties with pH values from 2.0 to 3.5 and the maximum coercivity is 1630 Oe. |

An Industrial DAQs and Internet Based Data Logging and Remote Monitoring System for Real-Time Multi-Parameters Measurements
Authors: Tran, Vinh Thang Do, Trung Kien Keywords: DAQ-data acquisition;data logger;remote monitoring system Issue Date: 2014 Publisher: H. : ĐHQGHN Series/Report no.: Vol. 30;No. 2 (2014) Abstract: In this paper, we proposed a design and implementation of a multi-parameters data logging and remote monitoring system for investigating both of electrical parameters and physical ones for indoor and outdoor environments. The task of logging and monitoring parameters are temperature, relativity light intensity and nineteen electrical parameters with storage and transmission of this information in the form cloud storage service to the user’s computer over internet in real-time for in-situ or further analysis. Due to industrial data acquisition modules, this system is easy to build with an expandable capability and enduring stability. Also a large of logged data can be measured by using this system with high accuracy and they are able to observe in a large surveying ar
