ChinaSIP 2013 Signal and Information Processing Conference

IEEE Signal Processing Society is pleased to introduce ChinaSIP 2013, the first IEEE China Summit & International Conference on Signal and Information Processing, 6-10 July 2013 at the China National Convention Center (CNCC), Beijing, China.

Sponsored by the IEEE Signal Processing Society (SPS), ChinaSIP is a new annual summit and international conference held in China for domestic and international scientists, researchers, and practitioners to network and discuss the latest progress in theoretical, technological, and educational aspects of signal and information processing. ChinaSIP is a unique platform developed by IEEE SPS to help colleagues in China engage with the global community, and offer global colleagues opportunities to network and develop international collaborations.

As the inaugural summit and conference, ChinaSIP 2013’s features include:

● Technical tracks and industry forum. Papers and presentations along the regular technical tracks as listed below focus on novel and significant research contributions. An industry forum provides a platform for exchange and networking among SIP industries as well as between academia and industry.

● Invited papers and open-call papers. Special invitations will be extended to major research groups in China to submit their latest contributions. Invited papers will be peer reviewed, and only papers with sufficient quality and significance will be accepted. In parallel, papers are also accepted through an open call from the community at large on a competitive basis.

● Journal poster sessions. Journal poster sessions provide a venue for overview and showcase of recent publications accepted by SPS journals.

● Professional development program. Several professional development activities will be organized, such as townhall meetings with the SPS leadership, trends/ overview sessions, publication (EIC/ AE) panels, and Fellow development sessions.

● Summer schools. The conference will set up summer schools before the regular sessions begin for students, researchers and practitioners to learn state-of-the-art technologies and tools.

The regular technical program tracks and topics include (but are not limited to):

● Signal/ Information Processing Theory and Methods
● Speech, Language, and Audio
● Image, Video, and Multimedia
● Signal Processing for Communications and Networking
● Signal Sensing, Radar, Sonar, and Sensor Networks
● SIP Hardware/ Software Designs and Systems
● Information Forensics and Security
● Pattern Recognition and Machine Learning
● Signal/ Info Processing for Bioinformatics & Bio/ Medicine.

Submission of Papers

The official language of the conference is English. Prospective authors are invited to submit up to 4 pages in length (with an optional 5th page containing only references). The conference proceedings will be published at IEEE Xplore, and will be indexed by both IEEE Xplore and EI Compendex. The IEEE Signal Processing Society enforces a “no-show” policy. Any accepted paper included in the final program is expected to have at least one author or qualified proxy attend and present the paper at the conference. Authors of the accepted papers included in the final program who do not attend and present at the conference will be added to a "No-Show List", compiled by the Society. The "no-show" papers will not be published by IEEE on IEEE Xplore or other public access forums, but these papers will be distributed as part of the on-site electronic proceedings and the copyright of these papers will belong to the IEEE.

Important Dates

Submission of regular full papers: January 10, 2013
Submission of special sessions and invited papers: February 1, 2013
Notification of paper acceptance: April 10, 2013
Authors registration deadline: May 10, 2013
Attendees advanced registration deadline: June 1, 2013
Summer school dates: July 6-7, 2013

Print a New Nose!

3D printing is a way of manufacturing physical objects directly from 3D computer models. 3D printers work in additive fashion, building an object layer upon layer, typically from resin or photopolymer, which may be pigmented for production of coloured objects. Even intricate forms can be produced quickly by this technology, making it ideal for one-off or short-run production.

3D printing is widely employed in product design, for rapid prototyping of such things as hand-held devices, car parts, jewellery or footwear designs, architectural or engineering components. In future it looks likely to extend into the manufacture of complex multi-part objects.

Amongst the most useful applications of this rapidly developing technology are in medicine, in the production of individually shaped items such as dental crowns and bridges, synthetic bones and joints, or artificial limbs and other prostheses.

Conventionally, prosthetic ears, eyes and noses have had to be individually hand-modelled and painted, a time-consuming process whose results have often been variable and unsatisfactory. For that reason Sheffield-based company Fripp Design and Research, who have extensive experience in 3D printing for industrial design, were keen to try and adapt the technology for prosthetic production. They identified a number of specific challenges:

"Creating fleshlike prostheses, as opposed to porcelain teeth or crowns, posed a unique set of challenges. The material used would have to be strong, flexible and biocompatible (unlikely to trigger a toxic or allergic reaction when inserted into human skin). The colour would have to match the patient's specific skin tone exactly, and the whole prosthesis would need to blend as invisibly as possible into the surrounding face."

In collaboration with researchers at Sheffield University and supported by The Wellcome Trust, Fripp have developed new ways of speeding production and improving the quality of soft-tissue prostheses. Key to the project has been the development of printable materials that are biologically inert, that can be safely worn in contact with human tissue and comply with relevant safety standards. After testing several materials, the research team found a starch powder that fit the bill and which can be combined with water-based resin and inks to produce a suitable printing medium.

The production process begins with 3D scanning of the part of the patient's face/ head to be augmented, along with 2D photos of skin tone and colour. Special CAD software is used to combine these datasets with a model of the new body part and to match the model's contours, tone and texture to the patient's face.

The resulting 3D file is output to the printer to make the prosthesis which, being quite brittle at first, has to be cured with a medical-grade silicone fluid to give it strength and pliability. Curing has a beneficial side effect: as the silicone drains off it forms a fine feathered edge that bonds seamlessly to the face.

The printed prosthesis is lighter in weight than a conventional hand-made one, and much more easily replaced when it wears out or gets damaged, as the stored product file can simply be reprinted.

This method of manufacture reduces the cost to the healthcare provider and delivers higher quality and consistency to the patient. The Sheffield researchers believe that the technology could be easily and inexpensively installed in centres across the developing world, making high-quality soft-tissue protheses widely available there.
