- Cyclops Markets Monitor (exe)
- In each analysis Cyclops processes data sets working on a present and past data basis and presents sets of results for the most successful investment histories. The method of analysis by finding correlations between data sets is a recognition that market data trends are mostly random when analyzed singly but...

- 4-D Wavelet-Based Multiview Video Coding
- The conventional Multiview Video Coding MVC schemes, utilizing both neighboring temporal frames and view frames as possible references, have only shown a slight gain over those using temporal frames alone in terms of coding efficiency. The reason for this is that the neighboring temporal frames exhibit stronger correlation with the...

- Correlations of Size, Rate, and Duration in TCP Connections: The Case Against
- This paper examines rigorously the evidence for correlations among size, rate, and duration in TCP connections. The use of robust statistical methods for studying correlations is emphasized. These methods are applied to three large data sets of TCP/IP packet traces from a diverse set of networks. The major results show...

- Introduction to Cisco Security Agent Correlation
- At a high level, Cisco Security Agent is straightforward. It intercepts system calls between applications and the operating system, correlates them, compares the correlated system calls against a set of behavioral rules, and then makes an "allow" or "deny" decision based on the results of its comparison. This process is...

- Assured Service Quality by Improved Fault Management
- The paradigm shift from device-oriented to service-oriented management has also implications to the area of event correlation. A correlation of user trouble reports concerning services should also be performed. This is necessary to improve the resolution time and to reduce the e ort for keeping the service agreements. This paper...

- Faster Correlation Attack on Bluetooth Keystream Generator E0
- This paper studies both distinguishing and key-recovery attacks against E0, the keystream generator used in Bluetooth by means of correlation. A powerful computation method of correlations is formulated by a recursive expression, which makes it easier to calculate correlations of the finite state machine output sequences up to 26 bits...

- The Conditional Correlation Attack: A Practical Attack on Bluetooth Encryption
- Motivated by the security of the nonlinear filter generator, the concept of correlation was previously extended to the conditional correlation, that studied the linear correlation of the inputs conditioned on a given short output pattern of some specific nonlinear function. Based on the conditional correlations, conditional correlation attacks were shown...

- Service-Oriented Event Correlation - The MNM Service Model Applied to e-Mail Services
- The paradigm shift from device-oriented to service-oriented management has also implications to the area of event correlation. However, the correlation of trouble reports from users needs to be addressed as well, because different reports could have the same cause. In such a case the reports could be linked together and...

- Scalable Robust Covariance and Correlation Estimates for Data Mining
- Covariance and correlation estimates have important applications in data mining. In the presence of outliers, classical estimates of covariance and correlation matrices are not reliable. A small fraction of outliers, in some cases even a single outlier, can distort the classical covariance and correlation estimates making them virtually useless. That...

- Using Copulas to Model Dependency Structures in Econometrics
- Modeling the correlation structures of economic variables is an important part of managing financial risk. Pearson correlation matrices fully characterize joint distribution when the underlying economic variables follow a multivariate normal distribution. When the economic variables are nonnormal, copulas are needed to model the correlation structure. In fact, given a...

- Using Extended Logic Programming for Alarm-Correlation in Cellular Phone Networks
- Though cellular phone networks already contain intelligent network elements diagnosing local faults, alarm bursts caused by network element failures cannot be handled properly by this technology. To deal with alarm bursts alarm correlation systems are required to filter and condense the incoming alarms to meaningful high-level alarms and diagnoses. This...

- Maximum Achievable Diversity for MIMO-OFDM Systems With Arbitrary Spatial Correlation
- In this paper, the maximum achievable diversity order is determined for MIMO-OFDM systems with arbitrary spatial correlation. This paper shows that the maximum achievable diversity order is the rank of the spatial correlation matrix of the channel including all delay paths. The paper also shows that any space-frequency code designed...

- Chaotic Sequences for Secure CDMA
- One family each of repetitive and non-repetitive spreading sequences for secure Direct Sequence Spread Spectrum communication are obtained from the logistic map. The repetitive sequences are perfectly balanced and are found to have sufficient linear complexity. Applicability of both the families to CDMA communication is studied by examining their cross-correlation...
