Delays in Lung Cancer Diagnosis: Observations from a Tertiary Care Centre in Kerala, India.

Merin Yohannan  Timely diagnosis of lung cancer is critical because treatment outcomes correspond to the stage of disease. This study identified patient and physician determined reasons for diagnostic delays. s This was an observational cross-sectional study, conducted at a tertiary care institution in South India, for 12 months.

Improving the dynamic response of neural network controllers using velocity reference feedback.

A neural network controller designed solely based on the desired response of the dynamics to realize a maximum acceptable steady-state error may not be the best one in terms of the transient responses. It may have an excessive overshoot and larger risetime. Similarly, a controller having a very good transient response may not have the desired steady-state characteristics.
