Dear friends, Institute of Quality and Reliability (IQR) is happy to release this first video in our series on statistical process control charts. In the video, Hemant Urdhwareshe, Director of IQR and Fellow of ASQ explains criteria for selection of control charts, and has illustrated how to plot X-bar and Range chart using Microsoft Excel with an application example. Hemant has also explained briefly the interpretation rules to detect special causes. The video is little long but request viewers to watch it till end for best viewing experience.

Dear friends, we are happy to release this video on fractional factorial design. In this video, Hemant Urdhwareshe has illustrated how to create a five-factor resolution-V design in Minitab (version 17) with an example of a virtual catapult (thanks to sigmazone.com)

Hello Friends! I am happy to release this video on Kaplan-Meier (KM) nonparametric method to estimate reliability. The KM method is used in situations when the data cannot be modelled using mathematical distributions such as Weibull, Lognormal etc. The KM method is popularly used in medical science to estimate survival probabilities of patients with diseases such as cancer, kidney diseases, etc.

Dear friends, This is Hemant Urdhwareshe! I am uploading this video, which is different from our other videos! In this video, I have explained the “Confusion Matrix” and related terms such as Sensitivity, Specificity, Accuracy with reference to RT-PCR Test to detect Covid-19 infection. I and my son were isolated for Covid-19 as I was detected Covid-19 positive before my return travel and then isolated for about a fortnight in Egypt! This video is a result of my experience and review of travel rules! I am sure you will find this interesting and thought-provoking!

Dear friends, I am happy to release our 59th video on Exponential Distribution! Exponential Distribution is an appropriate mathematical model when failure or hazard rate is constant. It is often known as “Memoryless” as reliability in any time interval is same! Exponential Distribution has many applications in Reliability Engineering such as electronic components. Many reliability procedures in MIL Standards assume constant failure rate and Exponential Distribution! Hope you find the video interesting and useful! Your feedback is welcome!

Dear All, This is our fourth video on Accelerated Life Testing (ALT). Some of the viewers had requested for procedure to determine the Activation Energy used in Arrhenius Model. This video explains experimental procedure to determine Activation Energy. Hope you find this useful!
