Rajesh Krishna Panta and Jin Kyu Koo discussing software needs of South Bend, Indiana
No full textPurdue electrical and computer engineering doctoral students Rajesh Krishna Panta, from right, and Jin Kyu Koo discuss software needed for a wireless sensor network in South Bend, Ind., to prevent raw sewage from overflowing into waterways, especially from surging runoff during storms. The software must be loaded into antenna-equipped miniature computing nodes to control a citywide network of 105 manhole-mounted sensors and ""smart valves."" The system is designed to automatically hold back the flow of rainwater and sewage in existing sewer system pipes and retention basins until the storm has passed. The stored water would then be released in a controlled manner for subsequent treatment by the city's wastewater treatment plant

Cloud hosted business-data driven BI platforms
No full textBusiness Intelligence in Platform as a Service (PaaS) for information analysis is increasingly being considered for its applications in the enterprises because of its advantages. It is widely used for Data Analysis, Customer Churn Prediction, etc. However, the challenges that the traditional BI platform faces includes the tremendous volume of data, high time and space complexity of algorithms and the incompatibility in the Integration to the BI tools. Thus instead of having traditional Data Warehouses for storage which require high maintenance and storages, companies are moving towards more efficient cloud based storages
Novel Battery-Less Wireless Sensors for Traffic Flow Measurement
No full textThis project presents a novel battery-less wireless sensor that can be embedded in the road and used to measure traffic flow rate, speed and approximate vehicle weight. Compared to existing inductive loop based traffic sensors, the new sensor is expected to provide increased reliability, easy installation and low maintenance costs. The sensor uses power only for wireless transmission and has ZERO idle power loss. Hence the sensor is expected to be extremely energy efficient. Energy to power this sensor is harvested entirely from the short duration vibrations that results when an automobile passes over the sensor.
A significant portion of the project focuses on developing low power control algorithms that can harvest energy efficiently from the short duration vibrations that result when a vehicle passes over the sensor. To this effect this report develops and compares three control algorithms “Fixed threshold switching”, “Maximum Voltage switching” and “Switched Inductor” for maximizing this harvested energy. The novel “Switched inductor” algorithm with a dual switch control configuration is shown to be the most effective at maximizing harvested energy. All three of the developed control algorithms can be implemented using simple low power analog circuit components.
The developed sensor is evaluated using a number of experimental tests. Experimental results show that the sensor is able to harvest adequate energy for its operation from the passing of every axle over the sensor. The sensor can reliably and accurately measure traffic flow rate.Vijayaraghavan, Krishna; Rajamani, Rajesh. (2008). Novel Battery-Less Wireless Sensors for Traffic Flow Measurement.

Enhancement and Field Test Evaluation of New Battery-Less Wireless Traffic Sensors
No full textThis project focused on the enhancement of a previous battery-less wireless traffic flow sensor so as to enable it to provide weigh-in-motion (WIM) measurements and provide enhanced telemetry distance. The sensor consists of a 6-feet-long device which is embedded in a slot in the road flush with the pavement. As a vehicle travels over the sensor, vibrations are induced in the sensor. Using piezoelectric elements, energy is harvested from the vibrations and used to power the electronics in the sensor for signal measurements and wireless transmission.
The sensor's performance was evaluated by embedding it in a slot in concrete pavement and driving various vehicles of known weight over it at a number of different speeds on different days. The sensor was found to meet the specification of 500 feet telemetry distance. It was able to provide WIM measurements with an accuracy of better than ±15% in the absence of vehicle suspension vibrations.
However, much of the WIM data during the latter period of sensor testing was obtained in the presence of significant suspension vibrations. The project also evaluated the use of 4 consecutive WIM sensors in the road to remove the influence of suspension vibrations.Intelligent Transportation Systems InstitutePruden, Sean; Vijayaraghavan, Krishna; Rajamani, Rajesh.

Assessment and Prevention Of Falls In Elderly: Nurses’ Role
No full textFalls in elderlies has been a major concern in geriatric care. One out of three elderlies have
been falling every year and the many more elderlies are constantly at risk of falls. These falls
lead to serious injuries like hip fractures and build sense of fear in elderlies, which limit their
activities and degrade their quality of life.
There has been seen a huge need to enhance the skill and knowledge of the present and future
nurses to ensure that they are professionally and personally capable to identify the risk factors
and plan prevention strategies accordingly.
Literature review has been used in this thesis to find out the possible assessment methods to
assess the risk factors of falls in elderly, the vulnerable groups of elderlies who have higher
chances of falling. In addition, the possible falls prevention strategies have been studied and
laid out in this thesis.
A total of 11 relevant articles were obtained from a reliable database search.
The contents of the thesis have been categorized into distinct assessment and prevention
headings for ease of reading and finding required information. In the conclusion end, the author has presented his own ideas and discussed the additional need for safety of elderlies

Influence of fracture orientation distribution function on the estimates of gas-hydrate saturation of site 10 at Krishna-Godavari Basin, India
No full textWe estimate the gas-hydrate saturation in fractured reservoirs of gas hydrate-rich marine sediments from Krishna-Godavari basin along the eastern margin of India. Effective medium modeling (EMM) is a combination of self-consistent approximation (SCA), differential effective medium (DEM) modeling and smoothing and it deals with the anisotropy associated with clay platelets’ orientation. It proves to be a good choice attributable to its dependency on physical parameters alone. Previous approaches appertain to the implementation of orientation distribution function (ODF) on clay platelets alone assuming a vertical ellipsoidal shape of gas hydrates whilst in the present study, we have implemented ODF on hydrate bearing fractures assigning an ellipsoidal shape to them as well. A bias of ~2-4% in the saturation estimates apparently streamlines the betterness of our method
