   About Me

 Aridaman (Ari) K Jain is a Senior University Lecturer in the Department of Mathematical Sciences at the New Jersey Institute of Technology (NJIT). He is also the coordinator of the Statistical Consulting Lab. Some of the recent consulting projects are included in the list of projects under the tab Projects.

 Before joining NJIT in 2003, he worked for 34 years at Bell Laboratories and Telcordia Technologies as Member of Technical Staff/Distinguished Member of staff/Technical Manager, where he made a broad range of technical contributions:

• Modeled computer performance,
• Developed sampling plans for measurement of billing accuracy,
• Conducted Reliability Review Forums (RRFs) for tracking the reliability performance of Telecom products,
• Developed a sampling plan for Factory EST of DDM-2000 system that reduced the manufacturing test interval and the testing costs by 50% - 70%, and
• Developed and presented an award-winning tutorial on reliability prediction during 1995-2001 Annual Reliability and Maintainability Symposiums.

Consulting Projects
 

1. NJ Meadowlands Commission

Conducted several studies on Statistical Modeling of the quality of air, water, and soil in the Meadowlands district (jointly with Prof. Ken Johnson):

• Developed a mechanized process of preparing summaries of the actual water quality data by listing all the measurements that are found to be outside the control limits
• Conducted a statistical analysis of the Benthics organism data from the two studies of sediments from 25 sampling sites in the Lower Hackensack River estuary and its major tributaries during 1987-88 and 2003 and identified statistically significant effects.
• Conducted a statistical analysis of the air sample data collected from 15 volunteers in eight municipalities in the vicinity of the Teterboro airport. Developed general linear models to describe the concentrations of Benzene, Ethyl benzene, Toluene, and Xylene as functions of environmental variables and other factors such as the distance from the airport and time spent indoor and outdoor.
• Analyzed the data collected from experiments designed to examine the hypothesis that hyperspectral images of wetland vegetation alone can be used as a surrogate for mapping wetland relative elevation and sediment chemistry measurements. Developed regression models for predicting the sediment chemistry and relative elevation measurements as a function of only remotely collected images; these models explain 30% to 65% of the total variability and do not have any lack-of-fit.
• Conducted a statistical analysis of the metal concentration and organic composites data collected from marine dredge in Northeast marsh and freshwater pond dredge in the Southeast marsh in October ’07 and June ’08. Estimated the effects of 2 levels of elevation, 2 marshes, 2 depths, and 2 time periods on metal and organic concentration. The statistically significant effects – both main and interaction – were identified.
   

2. NJ Attorney General

Developed two ballots – long and short – and the corresponding voting scenarios, based on fractional-factorial designs. These voting scenarios are being used for casting votes and collecting data generated in both paper records and electronic files for the testing of the new electronic voting machines. 

3. ASTM Standard E11

Developed 99% and 99.73% confidence intervals for the sample variances used for making acceptance/rejection decisions for inclusion in ASTM Standard E11 for the inspection of sieve openings in the warp and weft directions. 

4. Manalapan-Englishtown Regional Schools

Analyzed the effects of demographic variables on the performance of middle school students.
