The Context Toolkit: Aiding the Development of Context-Enabled Applications

by Daniel Salber, Anind K. Dey, Gregory D. Abowd - University of Karlsruhe , 1999
"... Context-enabled applications are just emerging and promise richer interaction by taking environmental context into account. However, they are difficult to build due to their distributed nature and the use of unconventional sensors. The concepts of toolkits and widget libraries in graphical user inte ..."

Seismic Systems for Unconventional Target Detection and Identification

by Alex Pakhomov , Tim Goldburt - Proc. of SPIE
"... ABSTRACT Seismic detection systems for homeland defense and security applications are an important additional layer to perimeter, border and zone protection. General Sensing Systems has been developing a novel method and corresponding software for footstep detection with a near zero false alarm rat ..."

rate. This method has been realized in a number of detection systems. The testing of the GSS seismic systems in various environment noise conditions showed that such systems can be successfully used for other target detection. Such "unconventional" targets can include light and heavy vehicles

Self-assembly of Micro-devices unto Unconventional Substrates

by Ehsan Saeedi, Samuel Kim, James R. Etzkorn, Babak A. Parviz
"... Active aircraft body surfaces require integration of various micro-devices and sensors over large areas. We have demonstrated a self-assembly method that is capable of integrating functional heterogeneous micro-components on unconventional substrates such as plastic and glass. This method could be a ..."

Unconventional TV detection using mobile devices

by Mohamed Ibrahim, Ahmed Saeed, Moustafa Youssef, Khaled A. Harras - in International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies , 2013
"... Abstract—Recent studies show that the TV viewing experience is changing giving the rise of trends like ”multi-screen viewing” and ”connected viewers”. These trends describe TV viewers that use mobile devices (e.g. tablets and smart phones) while watching TV. In this paper, we exploit the context inf ..."

information available from the ubiquitous mobile devices to detect the presence of TVs and track the media being viewed. Our approach leverages the array of sensors available in modern mobile devices, e.g. cameras and microphones, to detect the location of TV sets, their state (ON or OFF), and the channels

Fabrication of Functional Nanowire Devices on Unconventional Substrates Using Strain-Release Assembly

by John W. Durham, Yong Zhu
"... ABSTRACT: We report three representative nanowire (NW) devices for applications in stretchable electronics, strain sensing, and optical sensing. Fabrication of such devices is based on a recently developed strain-release assembly method. NWs are first aligned transversely on an elastomeric substrate ..."

unconventional materials (e.g., flexible and transparent materials). Following this combined process, flexible SiNW strain sensors are fabricated on plastics capable of sensing up to 1.6 % bending strain and gauge factors>1000; flexible zinc oxide NW ultraviolet sensors are demonstrated with quick recovery

Golgi Apparatus-Localized Synaptotagmin 2 Is Required for Unconventional Secretion in Arabidopsis

by Haiyan Zhang, Liang Zhang, Bin Gao, Hai Fan, Jingbo Jin, Miguel A. Botella, Liwen Jiang, Jinxing Lin
"... Background: Most secretory proteins contain signal peptides that direct their sorting to the ER and secreted via the conventional ER/Golgi transport pathway, while some signal-peptide-lacking proteins have been shown to export through ER/Golgi independent secretory pathways. Hygromycin B is an amino ..."

Synaptotagmins (SYTs) are involved in controlling vesicle endocytosis and exocytosis as calcium sensors in animal cells, while their functions in plant cells are largely unclear. Methodology/Principal Findings: We

Reconstitution and characterization of the unconventional splicing of XBP1u mRNA in vitro

by Sayoko Shinya, Hiroshi Kadokura, Yusuke Imagawa, Michihiro Inoue, Kota Yanagitani, Kenji Kohno , 2010
"... Upon endoplasmic reticulum (ER) stress, mam-malian cells induce the synthesis of a transcriptional activator XBP1s to alleviate the stress. Under un-stressed conditions, the messenger RNA (mRNA) for XBP1s exists in the cytosol as an unspliced pre-cursor form, XBP1u mRNA. Thus, its intron must be rem ..."

be removed for the synthesis of XBP1s. Upon ER stress, a stress sensor IRE1a cleaves XBP1u mRNA to initiate the unconventional splicing of XBP1u mRNA on the ER membrane. The liberated two exons are ligated to form the mature XBP1s mRNA. However, the mechanism of this splicing is still obscure mainly because

Sensor Noise Rejection

"... An inaccessible control architecture caused an undesirable influence on a UAV. The encountered noise in the performance was modeled using stochastic methods and a corrective term was implemented on an external controller. Our findings suggest that the sonar noise problem is unconventional may warran ..."
