This paper begins by stating that the underlying concepts of signals and antigen used by the Dendritic Cell Algorithm are too abstract and arbitrary to be of use in real world applications as they stand. To address this, these concepts are more explicitly defined within a specific application area, namely that of data stream analysis. These new definitions are based around the outputs of the Ch...

Distributed systems provide a framework to take advantage of the under used computing power of idle machines, and to attempt to solve problems too difficult for ordinary machines. This paper will attempt to define distributed computing and demonstrate the strengths, weaknesses, techniques, and theories behind distributed systems. The scope will include an introduction and discussion of distribu...

There has been considerable work done in the study of Web reference streams: sequences of requests for Web objects. In particular, many studies have looked at the locality properties of such streams, because of the impact of locality on the design and performance of caching and prefetching systems. However, a general framework for understanding why reference streams exhibit given locality prope...

Both multiple source data mining and streaming data mining problems have attracted much attention in the past decade. In contrast to traditional association-rule mining, to capture the quantitative association knowledge, a new paradigm called Ratio Rule (RR) was proposed recently. We extend this framework to mining ratio rules from multiple source data streams which is a novel and challenging p...

When a processing unit relies on data from external streams, we may face the problem that the stream data needs to be rearranged in a way that allows the unit to perform its task(s). On arrival of new data, we must decide whether there is sufficient information available to start processing or whether to wait for more data. Furthermore, we need to ensure that the data meets the input specificat...

Current database management system techniques are insuucient to support the management of multimedia data owing to their time-sampled nature. The extension of database systems to support multimedia applications thus requires new mechanisms to ensure the synchronized presentation of multimedia data streams. In order to exibly and eeciently present multimedia data streams to users, media streams ...

Recent years have witnessed a dramatic increase of user-generated video services. In such user-generated video services, crowdsourced live streaming (e.g., Periscope, Twitch) has significantly challenged today’s edge network infrastructure: today’s edge networks (e.g., 4G, Wi-Fi) have limited uplink capacity support, making high-bitrate live streaming over such links fundamentally impossible. I...

We describe a new technique for tracking and identifying multiple laser pointers simultaneously in a large screen collaborative environment. Our method is based on using a video camera to track and decode the laser pointers. We use an asynchronous serial bit stream created by blinking the laser light to encode the identity of each laser. Our goal is to use multiple laser tracking in large scree...
