ABSTRACT We describe the 2017 version of Microsoft’s conversational speech recognition system, in which we update our 2016 system with recent developments in neuralnetworkbased acoustic and language modeling to further advance the state of the art on the Switchboard speech recognition task. The syst[r]
The ASA 5505 supports a builtin switch. There are two kinds of ports and interfaces that you need to configure: • Physical switch ports—The ASA has 8 Fast Ethernet switch ports that forward traffic at Layer 2, using the switching function in hardware. Two of these ports are PoE ports. See the “Po[r]

In contrast, a routed protocol is a protocol that contains layer 3 information thatallows it to be moved from one destination to another. Examples of a routedprotocol include IP and IPX.Routing protocols can be divided into three types—distance vector, link state,and hybrid. The[r]
In this paper, we address the problem of assigning the sink role to a subset of nodes in a wireless sensor network with a given topology such that the resulting network configuration is robust against denialofservice type attacks such as node destruction, battery exhaustion and jamming. In order to[r]
Now a days the price forecasting plays a very essential role in a new electricity industry; it helps the independent generators to set up optimal bidding patterns and also for designing the physical bilateral contracts. In general, different market players need to know future electricity prices as t[r]
