Accessibility of information on the web [PDF]
Search engines do not index sites equally, may not index new pages for months, and no engine indexes more than about 16% of the web. As the web becomes a major communications medium, the data on it must be made more accessible.

Tunable Diode Laser Absorption Spectroscopy (TDLAS) has been widely applied in in situ and real-time monitoring of trace gas concentrations. In this paper, an advanced TDLAS-based optical gas sensing system with laser linewidth analysis and filtering ...

We propose a novel distributed denial of service (DDoS) attack suppression system that significantly reduces discarding of normal traffic (i.e., the traffic from Internet of Things (IoT) devices that are not infected with a malware) with a small number ...

The Low-Loss Spot Size Converter for Alignment with Cleaved Single Mode Fiber
Integrating the graded index (GRIN) waveguide with the 2-D inversely-tapered waveguide, a new design of spot size converter (SSC) has been proposed to couple the light beam between the cleaved single-mode fiber (SMF) and the silicon (Si) wire waveguide ...

Evaluating Information Retrieval and Access Tasks
This open access book summarizes the first two decades of the NII Testbeds and Community for Information access Research (NTCIR). NTCIR is a series of evaluation forums run by a global team of researchers and hosted by the National Institute of ...

We demonstrate a simple structure for the refractive index sensing by splicing a segment of capillary with two segments of single-mode fibers (SMFs). By selecting appropriate splicing parameters, two mode coupling regions can be formed with tapered air ...

Based on the scattering loss difference between the single-mode-fiber-optical-waveguide (SMFW) and multimode-fiber-optical-waveguide (MMFW) structures, a method to estimate the roughness of multimode rectangular optical waveguide (ROW) is proposed. Based
