In this paper, fabrication process of titanium-oxide nanowires, whose diameter and length were in the order of 10 nm and 1 mum, respectively, were successfully fabricated directly on a glass substrate and it's field-emission properties are discussed, in spite of the poor adhesion. This is profitable in realizing large-diagonal FED's and BLU's because glass is less expensive than a Si wafer and a titanium...
In this study, the structural changes in the electron beam-deposited Pt field emitter under field emission and field evaporation were investigated by in situ transmission-electron-microscope (TEM) observation. The structure of the Pt field emitter was found to be unchanged under field emission with an emission current of less than 480 nA. On the contrary, the top of the Pt field emitter was found...
This paper describes a quantitative measurement method for Young's modulus of nanometer-thick film materials by using a MEMS resonator array. The MEMS resonators fabricated by silicon micromachining techniques were designed to be driven at their resonant frequencies from 6.0 kHz to 35.5 kHz. From the difference in resonant frequencies between before and after deposition of these films onto the resonators,...
We propose a programmable and scalable traffic management scheme. Programmable traffic management at high-speed routers is difficult because programmability and high-speed packet processing have involved a serious tradeoff. To attain both, the new scheme combines control programs at a control server and simple packet handling functions, such as sampling packet headers and discarding packets, at routers...
The performance of the Message Passing Interface collective communications is a critical issue to high performance computing widely discussed. In this paper we propose a mechanism that dynamically selects the most efficient MPI Alltoall algorithm for a given system/workload situation. This implementation method starts by grouping the fast algorithms based on respective performance prediction models...
The car transportation system, which termed as iCART (intelligent cooperative autonomous robot transporters), is developed for handling the car in the narrow space, substituting the parking and unmanning the transportation of cars. iCART is composed of two robots and these robots transport the car in coordination based on a leader-follower type distributed motion control algorithm. To avoid damaging...
The performance of the message passing interface collective communication algorithms is a critical issue widely discussed in both academia and industry. In order to achieve and maintain high performance in the MPI implementations even in regard to random system behavior, the collective operations must be adapted to both the cluster platform and the workload of the user program. In this paper we propose...
Multiagent systems for information retrieval over large-scale networks are considered an effective technology and have received much attention. In a typical case, such information retrieval has time constraints, since the network contains too much information. In this paper, we assume that each retrieval result can be scored and propose a method to control agent execution to improve the score of the...
This article shows our research efforts toward the development of an olfactory display system for presenting odors with a vivid sense of reality. A multi-component olfactory display is developed, which enables generation of a variety of odors by blending multiple odor vapors with arbitrary ratios. In this research demo, the two contents using the olfactory display will be demonstrated. The first one...
A variety of smells can be realized by blending multiple odor components using an olfactory display. Since a set of odor components to cover the entire range of smells has not yet been known, we studied a method of selecting odor components using a large-scale mass spectrum database. Basis vectors corresponding to odor components were extracted by the NMF (nonnegative matrix factorization) method...
With advances in communication technologies, network services provided via the Internet have been widely diversified, and people can use these services not only via wired networks but also via wireless networks. There are several wireless systems in practical use such as cellular, WiMAX and WiFi. Although these wireless network systems have developed independently of each other, they should be integrated...
This paper proposes a method of directly measuring static constraints imposed by a human hand on a grasped object. Based on the analysis of the demonstration data of the human grasp, the static constraints are expressed as a combination of frictional force and normal force generated by the human hand. The static constraints are an important property to be mapped to robotic hands in the programming-by-demonstration...
In this paper, we propose an extraction method of ride comfort according to the difference of the tire by electroencephalogram (EEG). Recently, the sensory evaluation is used for development of the product. However, the sensory evaluation by a general user who doesn't have a clear standard is unstable. Moreover, ride comfort depends on the sensibility and the preference of the individual. It is considered...
Model based design can be used to address the challenges brought about by complex ECU designs. This paper introduces the use of models at various stages of ECU design and highlights their advantages. We particularly focus on the use of software models in ECU design and discuss their classification based on their use in the embedded system design flow. We discuss some of the issues involved in the...
Performance evaluation is a serious challenge in designing or optimizing reconfigurable instruction set processors. The conventional approaches based on synthesis and simulations are very time consuming and need a considerable design effort. A combined analytical and simulation-based model (CAnSO*) is proposed and validated for performance evaluation of a typical reconfigurable instruction set processor...
We demonstrate a prototype of a call-to-Web session linkage system for sharing a Web application between caller and receiver. The system makes a session linkage between Web browsers based on call session information of SIP, which is an application-layer control protocol mainly used for IP telephony systems. After that, the system offers Web servers information for the linkage so that Web servers can...
When multiple overlay networks are constructed over the same underlying IP network, overlay paths on different overlay networks may share some links on the IP network. In general, however, because overlay networks do not recognize the existence of each other, they have no consideration on such shared physical links. In this paper, a cooperative routing method for multiple overlay networks is proposed...
In this paper, we present a database of logical relations between predicate argument structures (PASs) in Japanese for recognizing relations between statements. We have defined nine logical relations between PASs and manually collected argument structures and logical relations for verbs from definition sentences in a machine-readable Japanese dictionary. In addition, we augmented the relations in...
This paper proposes a new UGC-oriented language technology application, which we call experience mining. Experience mining aims at automatically collecting instances of personal experiences as well as opinions from an explosive number of user generated contents (UGCs) such as Weblog and forum posts and storing them in an experience database with semantically rich indices. After arguing the technical...
We propose law professionals and amateurs supporting system for upcoming ??lay judge system??. The supporting system finds past cases which are similar to a target case and estimates a sentence of target case. After describing the need of such project, we carry out an preliminary experiment to extract similar judicial precedents and estimate a sentence based on features of noun words. Then we introduce...
