Connecting the adjacent buildings with dampers not only mitigates the structural response but also avoids pounding. In this paper, the seismic response of two adjacent buildings of fifteen and ten-story which are connected by a viscous damper are studied. Further optimization of the viscous dampers is carried out to get a better-mitigated response with less number of dampers. A comparison is done by considering the dampers which are underdamped and critically damped. The effectiveness of dampers in terms of the reduction of structural responses (i.e., displacements and base shear) of connected adjacent buildings is investigated. Results show that connecting the adjacent story buildings of different fundamental frequencies by these dampers can effectively reduce the earthquake-induced responses of either building. Results further show that critically damped dampers give better results than considered under damped dampers. [ABSTRACT FROM AUTHOR]

Automatic Karyotyping is the process of classifying chromosomes from an unordered karyogram into their respective classes to create an ordered karyogram. Automatic karyotyping algorithms typically perform geometrical correction of deformed chromosomes for feature extraction; these features are used by classifier algorithms for classifying the chromosomes. Karyograms of bone marrow cells are known to have poor image quality. An example of such karyograms is the Lisbon-K1 (LK1) dataset that is used in our work. Thus, to correct the geometrical deformation of chromosomes from LK1, a robust method to obtain the medial axis of the chromosome was necessary. To address this problem, we developed an algorithm that uses the seed points to make a primary prediction. Subsequently, the algorithm computes the distance of boundary from the predicted point, and the gradients at algorithm-specified points on the boundary to compute two auxiliary predictions. Primary prediction is then corrected using auxiliary predictions, and a final prediction is obtained to be included in the seed region. A medial axis is obtained this way, which is further used for geometrical correction of the chromosomes. This algorithm was found capable of correcting geometrical deformations in even highly distorted chromosomes with forked ends. [ABSTRACT FROM PUBLISHER]
