The perform ance of automatic speech recognition systems is usually assessed in terms of error rate. Human speech recognition produces few errors, but relative difficulty o f processing can be assessed via response time techniques. W e report the construction of a measure analogous to response time in a machine recognition system. This measure may be com pared directly with hum an response time...

Hypertrehalosaem ic horm ones I and II from the corpus card iacum o f the A m erican cockroach (Periplaneta americana) were separated by reversed-phase h igh-perform ance liquid chrom ato­ graphy using a N ucleosil C 18 colum n with a trifluoroacetic acid /aceton itrile gradient. T he eluent was monitored at 206 nm and the hypertrehalosaem ic activity detected by bioassay. T he am ino acid comp...

After induction the cell cu lture was fu rth er incubated in a production m edium in the absence o f the inducer for 10 days. T he extraction o f the freeze dried cel...

To maximize the utilization of its single-atom thin nature, a facile scheme to fabricate graphene multilayer films via a layer-by-layer self-assembled process was presented. The structure of multilayer films was constructed by covalently bonding graphene oxide (GO) using p-phenylenediamine (PPD) as a covalent cross-linking agent. The assembly process was confirmed to be repeatable and the struc...

A new permanent magnet design for axial flux interior permanent magnet (AFIPM) motor is described in this paper. Poleshoes are traditionally used to produce sinusoidal flux linkage and sinusoidal EMF especially in the case of radial flux synchronous machines. Poleshoes are not a practical solution in the case of axial flux PM machine. The use of poleshoes in the production of sinusoidal back EM...

A load stand has been built and used to det ermine the performance of an open type reciprocating r efrigeration compressor over a range of speeds. The load stand and instrumentation are desc ribed and sample test readings are given. Measured perform ance characteristics for the compressor over a range of speeds are p resented. Aspects of the load stand are discussed and conclusion s are drawn f...

A high capacity network adapter design is presented, using a CPU-based approach for shaping traffic, scheduling cells for multiplexing and controlling a DMA engine for a large number of ATM connections. By performing a scheduling operation for each cell, traffic shaping and data movement can be combined. Two scheduling algorithms are proposed, implemented and evaluated using detailed instrument...
