Continual observation on crop leaf area index using wireless sensors network

Crop structural parameter, i.e. leaf area index(LAI), is the main factor that can effect the solar energy re-assignment in the canopy. An automatic measuring system which is designed on the basis of wireless sensors network(WSN) is present in this paper. The system is comprised of two types of node. One is the measurement nodes which measured solar irradiance and were deployed beneath and above the canopy respectively, and another is a sink node which was used to collect data from the other measurement nodes. The measurement nodes also have ability to repeater data from one node to another and finally transfer signal to the sink node. Then the collected data of sink node are transferred to the data center through GPRS network. Using the field data collected by WSN, canopy structural parameters can be calculated using the direct transmittance which is the ratio of sun radiation captured by the measurement node beneath and above the canopy on different sun altitude angles. The proposed WSN measurement systems which is consisted of about 45 measurement node was deployed in the Heihe watershed to continually observe the crop canopy structural parameters from 25 June to 24 August 2012. To validate the performance of the WSN measured crop structural parameters, the LAI values were also measured by LAI2000. The field preliminary validation results show that the designed system can capture the varies of solar direct canopy transmittance on different time in a day, which is the basis to calculate the target canopy structural parameters. The validation results reveal that the measured LAI values derived from our propose measurement system have acceptable correlation coefficient(R2 from 0.27 to 0.96 and averaged value 0.42) with those derived from LAI2000. So it is a promising way in the agriculture application to utilize the proposed system and thus will be an efficient way to measure the crop structural parameters in the large spatial region and on the long time series.

Secure Sharing of Personal Health Record in Server with On-track ECG Monitoring

Personal Health Record (PHR) paved the way to the patient centric model of health information exchange. This service allows a patient to create, manage, and control her personal health data in one place through the web, which has made the storage, retrieval, and sharing of the medical information more efficient. But there have been wide privacy concerns about whether the patients could actually control the sharing of their sensitive Personal Health Information (PHI). This paper proposes a new patient centric framework and mechanisms for data access control to PHRs stored in semi-trusted servers using Attribute Based Encryption (ABE) technique. It focuses on the multiple data owner scenario, and divides the users in the PHR system into multiple security domain that greatly reduces the key management complexity for owners and users. It also proposes a new application for the on-track monitoring of patient's health data with the help of ECG device where communication between client and server is achieved through the GPRS network. The utilization of electrocardiogram transmission will improve efficiency of medical care and service for patients if they could be monitored constantly by health care providers. AES and ABE encryption techniques are used in my work. Keywords: Attribute based encryption (ABE), ECG, GPRS, Personal health record (PHR), secure sharing.

During periods of background seismicity large variations in temperature occur due to crustal deformation. Earthquakes are preceded due to ground lengthening, tilting or shortening. A large amount of heat energy at the earth's core tries to find a path to come out from one way or the other. In this paper, we present an instrumentation system to study the variations in temperature that occur prior to an earthquake. The changes in the temperature and relative Humidity are sensed by using Smartec sensors SMT16030 and SMTHS07.The Smartec temperature sensor SMT16030 is a sophisticated active full silicon temperature sensor with a digital output. The capacitive humidity sensor SMTHS07of Smartec is based on silicon technology on glass wafer. The sensors are powered by using solar panel. The output of the sensor is directly connected to a zigbee transceiver module. The data is further transmitted wirelessly over a distance of 120 metres by using Zigbee transceivers. ZigBee is an open global standard built on the IEEE 802.15.4 MAC/PHY. The received data is recorded and analyzed using PIC18F4520 microcontroller and further transmitted on to the Internet through the GPRS network.
