- New approach gives Purdue serious computing power
- Purdue University will be replacing its current research computing clusters on May 5th with one of the world's largest supercomputers. While this isn't especially surprising at a school known for its computer science expertise, the funding model and installation are far more novel. Interestingly, the supercomputer,...

- Cellphones to detect dirty bombs?
- Purdue University engineers are developing a system which would use a U.S. network of cellphones to detect dirty bombs and nuclear weapons. They say that 'such a system could blanket the nation with millions of cellphones equipped with radiation sensors able to detect even light residues of radioactive material.' They...

- Automated Rule-Based Diagnosis Through a Distributed Monitor System
- In today's world where distributed systems form many of the critical infrastructures, dependability outages are becoming increasingly common. In many situations, it is necessary to not just detect a failure, but also to diagnose the failure, i.e., to identify the source of the failure. Diagnosis is challenging since high throughput...

- High-Performance Network Intrusion Detection Through Parallelism
- Network intrusion detection has become increasingly popular in recent years due to the proliferation of Internet-based security attacks. Network Intrusion Detection Systems (NIDS) inspect the content of incoming packets on a network for known attacks and alert the operator when they are found. Intrusion detection is computationally expensive, and this...

- On the Impact of Bursting on TCP Performance
- Periodically in the transport protocol research community, the idea of introducing a burst mitigation strategy is voiced. This paper assess the prevalence and implications of bursts in the context of real TCP traffic in order to better inform a decision on whether TCP's congestion control algorithms need to incorporate some...

- Providing Automated Detection of Problems in Virtualized Servers Using Monitor Framework
- Increasing management costs with large servers have caused adoption of a technique called Server Virtualization whereby multiple virtual machines can be hosted on the same physical machine. Reduction in the number of physical machines and amount of rack space brings the total cost of ownership down. Virtual servers residing on...

- Performance Evaluation of Multiple-Rate Mobile Ad Hoc Networks
- Existing wireless networks usually provide multiple data transmission rates. This paper presents a simulation study on the performance of multiple-rate mobile ad hoc networks (MANETs), based on an evolved ns-2 simulator. At the physical layer, realistic models such as Walfisch-Ikagami radio propagation model and lognormal fading are implemented. This paper...

- Better 'robot manipulators'
- According to this news release from Purdue University, civil engineers, who deal with statics, and mechanical engineers, who deal with kinematics, have unified their efforts to create dual theorems which combine the mathematics of both kinematics and statics. In other words, they've shown that these concepts are in fact analogous....
