Using two unbalanced panel data sets of vessels over the periods 1990-1996 and 19942000 the paper estimates stochastic production frontiers and evaluates the effects on individual technical efficiency of inputs controls in the northern banana prawn fishery of Australia. The results indicate that technical efficiency is decreasing in the gear input headrope length that was restricted until 1993 ...

Asynchronous transfer mode (ATM) switches based on shared buffering are known to have better performance and buffer utilization than input or output queued switches. Shared buffer switches do not suffer from head of line blocking which is a problem in simple input buffering. Shared buffer switches have previously been studied under uniform and unbalanced traffic patterns. However, due to the co...

Pomaranch is a synchronous stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. It uses 128-bit keys and IVs with different lengths. The cipher is constructed as a cascade clock control sequence generator, which is based on the notion of jump registers. Each jump register can be considered as a non-autonomous finite state machine which the input sequence is called jump control ...

This paper presents a novel configuration of separate zigzag transformers based 18-pulse AC –DC converter for improving the ripple factor & isolation of three phase uncontrolled rectifier, this approach eliminates the complexity required to design a complicated auto transformers or isolated multi winding transformer as used with other systems. The paper also presents the comparison among 12 pul...

Parallel Packet Switches (PPS) use internal, parallel switch planes that operate at less than line speed. A PPS can scale-up to faster line speeds than a single-plane switch can. Load balancing between planes and providing QoS to flows are open problems. We investigate the performance of a new “VIQ PPS” that distributes cells or variable-length packets to planes and uses multiplexors with virtu...

A comparative study of routing techniques is carried out for LEO constellations interconnecting high speed terrestrial networks assuming Poison and Self-Similar input traffic. Shortest path routing as well as optimal routing (flow deviation) methods are applied for balanced and unbalanced traffic load and for uniform and non uniform distribution of the earth stations. The performance of flow de...

The precise mechanism by which synaptic excitation and inhibition interact with each other in odor coding through the unique dendrodendritic synaptic microcircuits present in olfactory bulb is unknown. Here a scaled-up model of the mitral-granule cell network in the rodent olfactory bulb is used to analyze dendrodendritic processing of experimentally determined odor patterns. We found that the ...

Evaluating performance of PMUs to verify the consistency of phasor measurements is of a great importance since it promotes the interoperability among PMUs from different manufacturers. This paper presents a set of test methodology and tools for evaluating the dynamic performance of PMUs when exposed to a step change of input signals. A phasor estimation scheme is proposed to achieve high accura...
