Dynamic Workload-Aware Elastic Scale-Out in Cloud Data Stores

NoSQL databases store a huge amount of data generated by modern web applications. To improve scalability, a database is partitioned and distributed among the different nodes called as a scale out. However, this scale out feature of the NoSQL database is oblivious to the data access pattern of the web applications, which results in poorly distributed data across all the nodes. Therefore, the cos...

The role of elastic energy storage and recovery in downhill and uphill running.

In level running, humans and other animals store and recover elastic energy during each step. What role does elastic energy play during downhill and uphill running? We measured the fluctuations of the mechanical energy of the center of mass (CoM) of 15 human participants running at 3 m s(-1) on the level, downhill and uphill on a force-measuring treadmill mounted at 3, 6 and 9 deg. In level run...

Scalable and Elastic Transactional Data Stores for Cloud Computing Platforms

Scalable and Elastic Transactional Data Stores for Cloud Computing Platforms by Sudipto Das Cloud computing has emerged as a multi-billion dollar industry and as a successful paradigm for web application deployment. Economies-of-scale, elasticity, and pay-peruse pricing are the biggest promises of cloud. Database management systems (DBMSs) serving these web applications form a critical componen...

The capacity of the human iliotibial band to store elastic energy during running.

The human iliotibial band (ITB) is a poorly understood fascial structure that may contribute to energy savings during locomotion. This study evaluated the capacity of the ITB to store and release elastic energy during running, at speeds ranging from 2-5m/s, using a model that characterizes the three-dimensional musculoskeletal geometry of the human lower limb and the force-length properties of ...
