The pervasive deployment of advanced sensing infrastructure in Cyber-Physical systems, such as the Smart Grid, has resulted in an unprecedented data explosion. Such data exhibit both large volumes and high velocity characteristics, two of the three pillars of Big Data, and have a time-series notion as datasets in this context typically consist of successive measurements made over a time interval. Time-series data can be valuable for data mining and analytics tasks such as identifying the "right" customers among a diverse population, to target for Demand Response programs. However, time series are challenging to mine due to their high dimensionality. In this paper, we motivate this problem using a real application from the smart grid domain. We explore novel representations of time-series data for BigData analytics, and propose a clustering technique for determining natural segmentation of customers and identification of temporal consumption patterns. Our method is generizable to large-scale, real-world scenarios, without making any assumptions about the data. We evaluate our technique using real datasets from smart meters, totaling similar to 18, 200, 000 data points, and show the efficacy of our technique in efficiency detecting the number of optimal number of clusters.

In 1980 the TAPPI Fluid Mechanics Committee initiated a survey of pilot plant paper machines. The results of this survey to date have provided information on 67 machines in 52 organizations worldwide. There are about an equal number of pilot machines in different types of organizations including research/educational institutions, paper machine suppliers and paper companies. Machine suppliers also have a wider range of machine systems including Fourdrinier, cylinder, twin and top wire facilities while most other organizations are equipped with Fourdrinier machines. Machine widths up to 51 inches and speeds up to 8200 ft/min were noted in this survey.
In this paper algorithms are developed and implemented in a software program for kinematic and dynamic analysis of two characteristic cams mechanisms with rotating cam profile and translating follower. The follower co...
