Design thinking, having applications in many fields, is emerging to be a pragmatic technique for facilitating Human Centred Design (HCD), a modern-day necessity, through a well-defined systematic process. This paper presents a case study detailing the application of design thinking principles to approach and develop solutions for the visually challenged to recognize the denomination of Indian currencies. Throughout the paper, specific implementations of design thinking principles have been detailed with emphasis on the key takeaways from the various stages. A comprehensive review of our approach compared to existing and unconventional applications has been provided to underline the importance of incorporating design thinking into emergent consumer-oriented solutions. A lot of research has been done in developing denomination classification models, however, there seems to be a lack of solutions designed through the perspective of a blind person who plays the critical factor in determining effectiveness once deployed. The design procedure helped us realize the importance of developing a simple user-friendly interface with a single input button and audio relays to guide the blind user during operation. Establishing a good platform for interaction and feedback was found to be critical in helping us modify and prioritize aspects such as achieving a low false-positive percentage and the addition of a high threshold Softmax function which made the solution design effective.

The infrastructure of IT-sector is heterogeneous and complex. It is difficult for a system administrator to manage these complex systems. This led to complex, unmanageable and insecure systems. A new approach to solve this problem is the IT infrastructure automation. Autonomic computing is the solution to manage complex infrastructure which provides "must have" solutions for the problems above. The increased resource utilization in IT made the enterprises to use the costly physical servers. These physical servers were under-utilized. Virtualization is a technology with efficient and better utilization of resources. Virtualization and autonomic computing are of major importance for the ITsector and could be successfully combined to reach the ideals of the autonomic computing. This paper presents a framework for automating live migration of virtual machines in virtualized environment using autonomic computing. This paper also addresses the types of attacks encountered during live migration of virtual machines.

Post-silicon validation is a major challenge due to finite controllability and observability of actual silicon and makes debug a complex task. The trace signals routed from CPUs and other sources are translated by sampling unit to time-stamped trace messages and stored in trace buffer. Time stamp generated is not the exact time at which event has occurred. Hence, trace data read from trace buffer in post-silicon environment is not accurate from debug perspective. This is corrected by finding the variable delay along with various paths observed between two viewpoints, one being the source at which the event occurs and the other being the destination where the event gets recorded. One method to achieve time accurate debug data is by correlating the time at which data transaction event occurs at the signal with the time at which the trace data for that particular transaction event gets time-stamped. The major advantage is the successful reconstruction of pre-silicon environment for that particular post-silicon environment and enabling data to be viewed on the fly.
