This brief announcement provides a high level overview of a parallel mark-split garbage collector. Our parallel design introduces and makes use of an efficient concurrency control mechanism based on a lock-free skip-list design for handling the list of free memory intervals. We have implemented the parallel mark-split garbage collector in OpenJDK HotSpot as a parallel and concurrent garbage col...

Lightweight and camera-equipped wearable devices such as Android-backed Google Glass— with their potential for wide-spread and mobile data capture—have piqued the imagination of technologists and privacy advocates alike. This paper describes an experimental system which confirms the feasibility of such devices for surveillance through live data collection and facial recognition. Furthermore, ev...

Most “Big Data” systems are written in managed languages, such as Java, C#, or Scala. These systems suffer from severe memory problems due to the massive volume of objects created to process input data. Allocating and deallocating a sea of data objects puts a severe strain on existing garbage collectors (GC), leading to high memory management overheads and reduced performance. This paper descri...

The wireless sensor network are liked due to monitoring the presence of situation in many applications like industrial, environmental sensing, health care monitoring.The energy capability is a crucial view in wireless sensor networks to overcome this problem the efficient technique of clustering is used to achieve more data transmission, long network lifetime, less time consuming process, minim...

outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...

The work presented in this thesis revolves around erasure correction coding, as applied to distributed data storage and real-time streaming communications. First, we examine the problem of allocating a given storage budget over a set of nodes for maximum reliability. The objective is to find an allocation of the budget that maximizes the probability of successful recovery by a data collector ac...
