An Intelligent Irrigation System with Voice Commands and Remote Monitoring of Field
V. Divya,A. Umamakeswari
Journal of Artificial Intelligence , 2013,
Abstract: Agriculture sector is the backbone of Indian economy. With the advent of electric motors, the burden of manual irrigation by farmers has mitigated a lot. But still frequent power cuts and voltage fluctuations have affected the proper irrigation of fields in many remote areas. There have been several innovative efforts to automate the irrigation of fields. This study proposed an automatic irrigation system based on voice commands from an illiterate farmer. A separate module for speech to text conversion is interfaced to the farmers mobile. The module uses the Hidden Markov Model for speech recognition and a Field Programmable Gate Array (FPGA) or processor based system to store the texts. Besides this, the system also includes a wireless network based remote monitoring of the field’s temperature and moisture. The voltage monitoring unit informs the farmer about the power availability in the field. The control unit is based on the Peripheral Interface Controller (PIC) controller and relays connected to the various valves. Controller shuts off the motor if the measured values of temperature and moisture have reached the prefixed levels. The proposed system would reduce the hardships of the farmer and helps in efficient utilization of water in the fields.
Impact of link breaks on AODV and AOMDV in MANET: A Performance Analysis
Lino Murali,Divya T V
International Journal of Electronics and Computer Science Engineering , 2013,
Abstract: MANETs are ad hoc multi hop networks, formed of mobile battery chargeable devices and commonly used in emergency situations. With its dynamic topology and limited energy level they often come across with link breaks. This paper analyzes how energy consumption of the mobile devices and density of mobile nodes affects the performance of MANET. AODV and AOMDV are reactive routing protocols used in MANET which handles link break due to node mobility and energy drain. Performance of AODV and AOMDV is analyzed in presence of link breaks using ns2 simulator. The results show AOMDV has better performance in throughput, end to end delay and packet delivery ratio compared to AODV only in presence of large network size and high mobility of nodes. Energy consumption and normalized routing load is high for AOMDV compared to AODV for all scenarios.

Divya Gakhar
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.94056
Abstract:

Purpose: The study undertakes to identify individual characteristics and their investment pattern. The individual characteristics include MBTI personality scores, risk taking behaviour, biases and investor demographics. Data and Methodology: A structured questionnaire was administered on 117 respondents in India. The questions were related to demographic variables, optimism bias, investment pattern and MBTI (Myers-Briggs Type Indicator®) personality assessment. The results were analysed using chi-square and ANOVA. Findings: The results show that presence of optimism bias in investors is influenced by marital status, nature of employment and work experience of investors. The Indian investors are majorly balanced or conservative out of the total sample in terms of risk taking behaviour. Risk taking attitude is affected by personality of individuals. Investment in high risk instruments is different among males and females, various age groups, marital status, and work place activity. Investment in medium risk instruments significantly differ for work experience on gender basis. Investment in low risk instruments does not differ for demographic variables of investors as all investors invest equally in safe investment mode. MBTI personality type is a less significant variable which directly affects investment patterns of Indian investors. The study can be useful for portfolio managers, investment advisors who can use it for designing investment portfolios and products for their clients based on their demographic, and behavioural profiling. Originality: This study identifies relationship between investment pattern, behavioural biases and demographic characteristics of Indian investors. MBTI personality assessment is one new dimension which is less researched in studying investment behaviour in Indian context.

SMART IRRIGATION TECHNIQUE USING VOCAL COMMANDS
V.Divya,A.Umamakeswari
International Journal of Engineering and Technology , 2013,
Abstract: In this wireless communication era, mobile phones have become a necessity in the common man’s life. Besides being capable of making calls and sending messages, the latest advancements in mobile phones facilitate them to connect to the internet also. With these capabilities, there has been an unprecedented use of mobile phones in many areas of automation. One such area where mobile phone can help with the automation is irrigation process. The main aim of the work is to simplify the method of irrigation using vocal commands through the mobile phone. The Farmer just needs to call a fixed number and utter the control commands through his phone. The control system at the field involves a PIC microcontroller interfaced with GSM modem to receive the command from the farmer and a voice recognition unit which decodes it. The motor is turned on/off according to the decoded commands by the controller. In addition, the system also sends back a message to the farmer’s mobile about the action that has taken place. The power detection and battery backup unit helps in detecting the power availability in the field and inform the farmer about the same, even if the there is no supply at the field. The moisture sensor attached to the system helps in collecting the moisture content of the soil and switch off the motor after it reaches the required value.

ORIGINAL ARTICLE: Identification of Practical Pharmacology Skills Useful for Good Clinical Practice
C Ramachandra Bhat,V. Shilpa, R. Divya
Journal of Krishna Institute of Medical Sciences University , 2012,
Abstract: Background: Awareness about animal ethics is increasing everywhere. This increased awareness coupled with strict regulations discouraging the use of animals for routine experiments have tied the hands of many pharmacologists. They are now forced to develop alternative experiments without using animals. At present, there is acute need to come out with more innovative and useful practical exercises for pharmacology practical sessions. In this background, the present study was undertaken to develop the much-needed alternative experiments. Aims and Objective: To identify new pharmacological practical skills useful for good clinical practice. Material and Methods: A pre-tested questionnaire was administered to 110 doctors of different categories like house surgeons, postgraduate students, assistant professors and professors who are working in a tertiary care hospital. They were asked to give their suggestions regarding new pharmacology practical skills useful for good clinical practice. Statistical analysis: Responses of the participants to the questions asked were tabulated and analyzed. Suggestions given by them were listed out and studied. Results: Use of emergency drugs, dosage calculation, drugs used in pregnancy, case discussions and prescription writing exercises received a lot of support from the participants. Research methodology, cost calculation, animal experiments and interpretation of data of animal experiments did not receive support from the participants. Suggestions given by the participants regarding useful pharmacological skills belonged to the areas like therapeutics, safe use of drugs, recent advances, analysis of information given by the medical representatives and analyzing articles in journals for knowing the efficacy of drugs. Conclusion: Exercises relevant to the clinical practice, as identified in this study, can be introduced as practical pharmacology exercises. Steps are to be taken to highlight the importance of research methodology and pharmaco-economics to the undergraduates.

Wireless Engineering and Technology (WET) , 2013, DOI: 10.4236/wet.2013.43020
Abstract:

In this paper we have accomplished one of the tasks of cognitive radio i.e. dynamic spectrum sensing by using wavelet based Synchrosqueezing transform [1], a novel technique, which was proposed to analyze a signal in time-frequency plane. The distinctive feature of this transform compared to other techniques is that it enables us to decompose amplitude and frequency modulated signals and allows individual reconstruction of these components. The objective is also to separate the occupied band into amplitude modulated and frequency modulated bands.

Agent Based Software Testing Framework (ABSTF) for Application Maintenance
K. Karnavel,V. Divya,Gnanakeerthika,P. Karthika
Computer Science , 2013,
Abstract: Software testing framework can be stated as the process of verifying and validating that a computer program/application works as expected and meets the requirements of the user. Usually testing can be done manually or using tools. Manual testing can be time consuming and tedious, also it requires heavy investment of human resources. Testing tools in fact have many advantages and are widely used nowadays, but also has several disadvantages. One particular problem is that human intervention is no longer needed. Testing tools are of high cost and so, it cannot be used for small companies. Hence in this paper we propose Agent based testing, which is a fast growing approach in testing field. The proposed system (ABSTF) has to reduce the application testing moment, easily find out bug and solve the bug by Regression Testing. Here by we are going to use a safe efficient regression selection technique algorithm to selectively retest the modified program. We also use Traceability relation of completeness checking for agent oriented system, which identifies missing elements in entire application and classifies defect in the testing moment. With the ability of agents to act autonomously, monitoring code changes and generating test cases for the changed version of code can be done dynamically.
