 Salah satu metode yang digunakan untuk melakukan analisa percepatan tersebut adalah Analisis Pertukaran Waktu dan Biaya (Time Cost Trade Off Analysis) diolah d...

In responses to Norheim’s editorial, this commentary offers reflections from Thailand, how the five unacceptable trade-offs were applied to the universal health coverage (UHC) reforms between 1975 and 2002 when the whole 64 million people were covered by one of the three public health insurance systems. This commentary aims to generate global discussions on how best UHC can be gradually achieve...

We consider heterogeneous distributed storage systems (DSSs) having flexible reconstruction degree, where each node in the system has nonuniform repair bandwidth and capacity. In particular, a data collector can reconstruct file using some $$k$$ nodes and, for failure, be repaired by set of active nodes. Using min-cut bound, we investigate fundamental trade-off between costs our model DSS. Fur...

Imperialist competitive algorithm (ICA) is a new socio-politically motivated global search strategy. The ICA is applied to hybrid composite laminates to obtain minimum weight and cost. The approach which is chosen for conducting the multi-objective optimization was the weighted sum method (WSM). The hybrid composite Laminates are made of glass/epoxy and carbon/epoxy to combine the lightness and...
