In this paper, we describe a novel data transfer scheme that uses the camera in a smart phone as an alternative data channel. The data is encoded as a sequence of 2-D barcode images, displayed on a flat panel display, acquired by the camera, and decoded in real time by the software embedded in device. The decoded data is written to a file. Compared with existing data channels, such as CDMA/GPRS...

Scientific computations and collaborations increasingly rely on the network to provide high-speed data transfer, dissemination of results, access to instruments, support for computational steering, etc. The Energy Sciences Network is establishing a science data network to provide user driven bandwidth allocation. In a shared network environment, some reservations may not be granted due to the l...

The paper describes SABUL, an application level data transfer protocol for data intensive applications over high bandwidth-delay product networks. SABUL is designed for reliability, high performance, fairness, and stability. This unidirectional protocol uses UDP to transfer data and TCP to send back control messages. A rate based congestion control that tunes the inter-packet transmission time ...

The hol-4 proof system has been used to formally verify the correctness of the ARM6 micro-architecture. This paper describes the specification and verification of one instructions class, block data transfers; these are a form of load-store instruction in which a set of up to sixteen registers can be transferred atomically. The ARM6 is a commercial RISC microprocessor that has been used extensiv...

Very Long Baseline interferometry (VLBI) is a well established technique in radio astronomy for the study of celestial sources at high angular resolution. VLBI is gradually moving to the point where Gbps data rates are becoming routine. A number of experiments have shown that the internet can be used at data rates of several hundred Mbps on production networks. However the use of switched light...

Phase locked loops for data links operating at 10 Gb/s or faster are low phase noise devices designed to operate with a low jitter reference clock. Characterization of their jitter transfer function is difficult because the intrinsic noise of the device is comparable to the random noise level in the reference clock signal. A linear model is proposed to account for the intrinsic noise of a PLL. ...

we proposed a link protocol called Burstoriented Transfer with Time-bounded Retransmission (BTTR) for wireless real-time communications. This scheme uses a large transmission window for sending/receiving a burst of timesensitive data, and within this window, another smaller observation window is repeatedly used for dynamic error retransmission(s). There is time limitation on each retransmission...

Information represented in a digitized image format (such as remote sensing, satellite, or photographic images) is becoming more readily available. These image files contain massive amounts of information requiring more efficient storage and transfer methods. The large size of these image files requires investigation of quality issues, transfer methods, and storage mechanisms. Digitized image d...

In this paper, we present the TED Talks dataset which exposes all metadata and the actual transcripts of available TED talks as structured Linked Data. The TED talks collection is composed of more than 1800 talks, along with 35 000 transcripts in over 30 languages, related to a wide range of topics. In this regard, TED talks metadata available in structured, multilingual and HTTP-accessible for...
