We have designed a heterogeneous mesh router for wireless mesh networks (WMNs), using a network processor. WMN is a multi-hop wireless network, comprising two kinds of nodes - mesh routers and mesh clients. One of the primary concerns in such networks is that of routing in a heterogeneous setup. Microsoft Research has developed a mesh connectivity layer (MCL) for computers that use Windows operating...
The method of calculating symmetrical short circuit current is unambiguous. However, the process for calculating the asymmetrical short circuit current and selecting a circuit breaker to interrupt the required asymmetrical short circuit current of the system has several alternative methodologies that have been applied. There are differences in approach for selecting the multiplying factor to ascertain...
The generator circuit breaker (GCB) is a core component of a power plant, protecting both the generator and the power transformers. Currently, the only standard that addresses GCB ratings is IEEE C37.013. This standard defines the primary short circuit rating of a GCB based on a system fed fault. When attempting to determine the required ratings for a GCB, it is sometimes difficult to check the capability...
This work pioneers a generic and flexible approach to intrinsically evolve large digital circuits. One of the popular ways of handling the scalability problem prevalent in evolvable hardware (EHW) and evolve large circuits is to partition the circuit, evolve the individual partitions and then compact them. However, as the partition sizes become larger, this method also fails. This drawback is overcome...
Mobility of the nodes in a mobile ad hoc network poses a challenge in determining stable routes in the network. It is often difficult to predict the mobility of the nodes, as they tend to be random in nature. However, a non-random component would also exist in many scenarios. It is this non-random behavior that we consider in this paper to identify the movement trace of the mobile nodes. An algorithm...
An inevitable collision state (ICS) for a robotic system is a state for which, no matter what the future trajectory followed by the system is, a collision with an obstacle eventually occurs. The ICS concept takes into account both the dynamics of the robotic system and the future motion of the moving objects of the environment. For obvious safety reasons, a robotic system should never ever end up...
The introduction of deep packet inspection technique has enabled the provision of 'application-specific' QoS. Application-aware processing is a natural extension of this 'higher layer header examination' technique. The introduction of multicore, programmable, network processors has largely contributed to this extension. In addition to network-specific services inherently supported by the NP architecture,...
This paper presents a new approach of online generation and tuning of fuzzy inference systems (FIS) using unsupervised learning (OGFIS-UL). The proposed approach is capable of generating the antecedents of the FIS and selecting the best consequents automatically. The antecedents are generated and tuned using the fuzzy multi-agent structure learning (FMASL) and the consequents are selected using reinforcement...
This paper discusses a set of algorithms for performing Variable Long Precision Arithmetic (VLPA) and their implementation on a reconfigurable hardware. These algorithms are characterized by a high degree of similarity, scalability and massive parallelism. Due to these features, a reconfigurable target provides for a reduced design time, easy scalability and the ability to make a cost performance...
