Errors in the design and implementation of operating system kernels and system programs lead to security problems that very often cause a complete breakdown of all security mechanisms of the system. We present the architecture of the JX operating system, which avoids two categories of these errors. First, there are implementation errors, such as buffer overflows, dangling pointers, and memory l...

supply chain network   receding horizon control demand move suppression term   supply chain networks are interconnection and dynamics of a demand network. example subsystems, referred to as stages, include raw materials, distributors of the raw materials, manufacturers, distributors of the manufactured products, retailers, and customers. the main objectives of the control strategy for the suppl...

An artificial neural network can be used as an intelligent controller to control non-linear, dynamic system through learning. It can easily accommodate non-linearities and time dependencies. Most common multi-layer feed-forward neural networks have the drawbacks of large number of neurons and hidden layers required to deal with complex problems and require large training time. To overcome these...

quorum-based power saving (qps) protocols allow “asynchronous” wireless hosts, operating in a multi-hop ad-hoc network, to tune to the low power mode conceived in ieee 802.11 mac standard. qps schemes guarantee that the wake-up schedule for every two neighboring hosts would ultimately overlap within a bounded latency so as to be able to accomplish their reciprocal “unicast” communications. a ma...

We propose a method to measure available network bandwidth using the Internet Control Message Protocol (ICMP). The recently proposed ImTCP technique uses Transmission Control Protocol (TCP) data packets and the corresponding acknowledgement responses to measure the available bandwidth between sender and receiver. Since ImTCP needs to change the sender’s TCP implementation, it needs modification...
