Improving the energy efficiency in heat exchanger networks (HENs) remains a significant industrial problem, specifically energy-intensive operations. A particular method for such an objective is modification of HENs at equipment-use level, where structural changes take place and units within network are moved, replaced and/or removed. This practice usually known as retrofit. The retrofit to max...

Current research efforts are being directed to commit with the long-term view of self-management properties for telecommunications networks. One of the key approaches that have been recognised as an enabler of such a view is policy-based management. Policy-based management has been mostly acknowledged as a methodology that provides flexibility, adaptability and support to automatically assign n...

Because the underlying physiology of pathological tremor in a Parkinson's patient is not well understood, the existing physical and drug therapies have not been successful in tremor treatment. Different mathematical modeling of such vibration has been introduced to investigate the problem and reduce the existing vibration. Most of the models have represented the induced vibration as a sinusoida...
