 CAMP Professor Kerop Janoyan Involved in New Water Quality Measurement Project

IM Sensor

Novel low-cost, exceptionally small size approach (when compared to a US penny) to 6-DOF Inertial Measurement (IM) sensor system employing only linear accelerometers – an IM sensor is displayed on the left.

CAMP Professor Kerop Janoyan, Associate Professor and Executive Officer of the Civil & Environmental Engineering Department, is concerned with environmental protection that relates to bodies of water.  This involves monitoring the health of ecosystems by sampling for constituents of interest either on a continuous basis or in response to episodic events.  He and other members of the investigating team plan to measure water quality using a buoyancy controlled drifting sensor platform (BCDSP). See Figure 2. They propose to develop an inexpensive sensor-sensor platform for water quality monitoring by integrating sensors with a novel current measurement device derived from a six-degree-of freedom inertial navigation system (6-DOF INS). Density stratification in surface waters such as lakes, bays, and estuaries has been shown to contribute to the bio-geochemical cycling of material that aquatic life forms depend upon for growth and survival.

Understanding biochemical cycling and transport processes requires long-term time-series measurements of important water quality parameters within a water column. Synchrony of multi-parameter observations which are traditionally derived from multiple instruments that have different sampling rates has always been a challenge for scientists and water resource managers. This group’s objectives are to integrate 6-DOF INS with a suite of sensors as a low-cost mobile sensor platform with vertical profiling capability,develop a buoyancy control system for the sensor-sensor platform and develop algorithms for instrument control, data analyses, post processing, and telemetry.

The BCDSP will profile the water column under buoyancy control and will be integrated with dissolved oxygen (DO), chlorophyll-a (chl ‘a’) and chromophoric dissolved organic matter (CDOM) sensors to measure constituents of interest. By integrating the sensors and sensor platform into one unit with on-the-fly data synchronization, Professor Janoyan and the other researchers will be able to derive location and time-stamped concentration profiles within the water column in near real-time. The result will be a relatively inexpensive sensor/sensor platform with the capability to operate in relatively shallow waters.  Team members include Clarkson investigators Dr. Temitope Ojo, Dr. James Bonner, Dr. Matthew Whelan along with Dr. Kerop Janoyan.



CAMP Professors Cetinkaya and Issen Acquire a New X-Ray Unit

 
 

 

CAMP Professors Cetin Cetinkaya and Kathleen Issen, both of Clarkson’s Department of Mechanical and Aeronautical Engineering, have obtained an X-ray Microtomography system with funding from the National Science Foundation.  This tool supports various research groups and enables diverse research and education projects at the University.

The new system adds advanced experimental capabilities to modernize Clarkson’s mechanical characterization and testing methods, which serve many innovative, multidisciplinary research projects. The X-ray Microtomography system will have very significant impact on the fundamental understanding of various mechanical, aerospace, civil, bio-mechanical and biological systems under investigation at the University.

A broad range of fundamental and applied proposed research will utilize the system, including: investigation of the mechanical and pharmaceutical properties of advanced drug tablets, health/biological effects of nanoparticles, characterization of nanocomposites and self-healing materials, interstitial fluid flow and osteoporosis-induced compression fractures in cancellous vertebral bone, investigation of CO2 sequestration in porous geomaterials, fatigue failure in metal foams, and permeability of enhanced porosity concrete. These problems are collaborative and cross-disciplinary in nature. Therefore, the PIs will be from various departments such as Mechanical & Aeronautical Engineering (MAE), Biology, Civil & Environmental Engineering (CEE), Chemistry & Biomolecular Science, Electrical & Computer Engineering (ECE), and Physics. This X-ray Unit will open new research opportunities in Clarkson’s three major research focus areas: Advanced Materials, Biomedical/Rehabilitation Science/Engineering, and Environmental Science/Engineering.  The imaging features of X-ray Microtomography are essential for the success of Clarkson’s planned and ongoing research activities. The scanning system will also enable the academic community to acquire new knowledge and a fundamental understanding of the mechanics of porous/cellular materials, composite materials, and biological systems.
