Winning business idea at TU/e's Entrepreneurship workshop. Was based on business ideas for an Android/Apple-online-store-type of 3-D printing platform where users can buy and sell designs online.

This involved ensuring the technical competence and compliance to specifications of products of companies who wished to purchase the Honeywell brand name.The products included CFL bulbs, Generator sets, a Water purifier and an Air Cooler System. The project involved the development of test procedures to ensure quality conformance and the running of many of these tests.

This involved searching for alternate suitable electronic components from suppliers when supply for existing components in Honeywell Avionics electronic boards was stalled. This involved matching specifications of the component with those from various suppliers, contacting the suppliers and using the supplier’s test data for the component in an in-house statistical tool to determine if reliability standards were met.

The project involved applying Reverse Engineering principles for technology benchmarking in order to access the technological feasibility in getting into the Split AC market.

Value engineering involves the application of tools and techniques with the purpose of improving the value of a mature product, either by reducing cost and/or by increasing the functionality of the product under study. This requires innovative thinking in order to come up with business viable ideas to achieve the same. In general, the projects involve studying the product, reverse engineering the product and developing an approximate Bill of Materials (BOM) for the same with help from relevant… Show more

Value engineering involves the application of tools and techniques with the purpose of improving the value of a mature product, either by reducing cost and/or by increasing the functionality of the product under study. This requires innovative thinking in order to come up with business viable ideas to achieve the same. In general, the projects involve studying the product, reverse engineering the product and developing an approximate Bill of Materials (BOM) for the same with help from relevant specialists, benchmarking it with competitor products in the market, pointing out the technological differences and proposing ideas to improve the value of the product. This was done for a Miniature Circuit Breaker (MCB) that was a part of the Honeywell product portfolio. Show less

• Modelling:
A 4-stroke, 4-cylinder engine system with closed loop fuel injection and Exhaust Gas Recirculation (EGR) control was designed in the industry standard software tool AMESim™ and for the purposes of this work, simulates a real engine system. A mean value engine model (MVEM) that describes the dynamic averaged states of engine variables was developed in MATLAB™. This is based on a number of engine maps that are derived from simulation experiments on the original AMESim™ model.

• Modelling:

A mean value engine model (MVEM) that describes the dynamic averaged states of engine variables was developed in MATLAB™. This is based on a number of engine maps that are derived from simulation experiments on the original AMESim™ model.
• Estimation and Fault residual Generation:
Input measurements and noisy asynchronous sensor measurements are obtained from the AMESim™ for a particular test profile. A post-processing algorithm was designed to suitably smoothen and fuse this data for use in Extended Kalman Filter (EKF) or Unscented Kalman Filters (UKF) based Estimators (State Observers). Several such Estimators work in parallel, each of which use an MVEM that has been suitably designed for a particular fault. The estimators use the fault model and the sensor measurements to estimate averaged states and generate appropriate fault residues.
• Fault Diagnosis:
The residues from parallel estimators are fed to the diagnoser that uses isolation logic based on the principles of structured residuals to detect, isolate and identify the fault. Thresholds for multi-level hypothesis testing is developed using statistical principles (risk functions) to reduce false alarm rates and missed detections. Dempster-Shafer’s theory of combination of evidence is used to combine the evidence from various hypothesis tests and to generate a final decision statement. In this work, an MVEM based fault Diagnoser was built to detect sensor faults and manifold leaks.
