Blueprint for introducing innovation into wireless mobile networks

Abstract: In the past couple of years we've seen quite a change in the wireless industry: Handsets have become mobile computers running user-contributed applications on (potentially) open operating systems. It seems we are on a path towards a more open ecosystem; one that has been previously closed and proprietary. The biggest winners are the users, who will have more choice among competing, innovative ideas.The same cannot be said for the wireless network infrastructure, which remains closed and (mostly) proprietary, and where innovation is bogged down by a glacial standards process. Yet as users, we are surrounded by abundant wireless capacity and multiple wireless networks (WiFi and cellular), with most of the capacity off-limits to us. It seems industry has little incentive to change, preferring to hold onto control as long as possible, keeping an inefficient and closed system in place.This paper is a "call to arms" to the research community to help move the network forward on a path to greater openness. We envision a world in which users can move freely between any wireless infrastructure, while providing payment to infrastructure owners, encouraging continued investment. We think the best path to get there is to separate the network service from the underlying physical infrastructure, and allow rapid innovation of network services, contributed by researchers, network operators, equipment vendors and third party developers.We propose to build and deploy an open - but backward compatible - wireless network infrastructure that can be easily deployed on college campuses worldwide. Through virtualization, we allow researchers to experiment with new network services directly in their production network.

Silicon oxide film formation method

Abstract: An object of this invention is to provide a silicon oxide film formation method capable of enhancing efficiency for generating atomic oxygen and improving film quality of a silicon film (SiO 2 film) in forming the silicon oxide film using an RS-CVD system. This object is attained by adding nitrogen atom containing gas (N 2 gas, NO gas, N 2 O gas, NO 2 gas or the like) to oxygen atom containing gas (O 2 gas, O 3 gas or the like) introduced into a plasma generating space in the vacuum container to produce plasmas by these gases and to thereby increase the quantity of the atomic oxygen generated by the plasmas in the plasma generating space.

Pay Less Attention with Lightweight and Dynamic Convolutions

Abstract: Self-attention is a useful mechanism to build generative models for language and images. It determines the importance of context elements by comparing each element to the current time step. In this paper, we show that a very lightweight convolution can perform competitively to the best reported self-attention results. Next, we introduce dynamic convolutions which are simpler and more efficient than self-attention. We predict separate convolution kernels based solely on the current time-step in order to determine the importance of context elements. The number of operations required by this approach scales linearly in the input length, whereas self-attention is quadratic. Experiments on large-scale machine translation, language modeling and abstractive summarization show that dynamic convolutions improve over strong self-attention models. On the WMT'14 English-German test set dynamic convolutions achieve a new state of the art of 29.7 BLEU.

Router and network connecting method

Abstract: Route information used for dynamic route control can be shared by an active router and a standby router even in normal operation. After route calculation is performed according to a routing protocol, the calculated route information can be shared, enabling efficient operation. Protocol engine sections (31a to 31d) communicate with routers (41, 42), calculate a route to be selected for the routing according to the corresponding protocol. When the route information is altered, a route sharing information transmitting section (33) transmits the route information to the standby router. The protocol engine section in each router acting as an active router communicates with the router (41, 42), calculates a route to be selected for the routing according to the corresponding protocol, and transmits the route information, if it is altered. A route sharing information receiving section (34) receives the route information.
