(Press-News.org) Redevelopment of the London King's Cross station and the nearby neighborhood was announced in 2005 and completed with a grand opening in 2012. The internationally well-recognized engineering services firm Arup, famous among other things for their work on the Opera House in Sydney, Australia, and the Allianz Arena in Munich, worked on this 400 million pound construction project. In the process, the area to the north of the station including 50 new buildings, 2,000 new apartments, 20 new streets and ten new public squares was being renewed. Thus, a great challenge was to ensure that all project partners had consistent, up-to-date data that could be visualized.
"What has already been standardized for product data is not yet common for all 3D data, and therefore takes a lot of effort," explains Kristian Sons, who is doing his PhD at the faculty of Computer Graphics at Saarland University in Saarbruecken, and does research at the German Research Center for Artificial Intelligence (DFKI), only a few yards away. Some companies maintain Excel sheets manually or develop custom 3D visualiations using computer game technologies. Another challenge for Arup was to present the plan and its progress to the investors and the general public in a way that was easy to understand. Engineering drawings are only suitable for experts. Artistic impressions, on the other hand, do not meet technical specifications, and public exhibitions are too costly and time consuming.
Therefore, the Saarbruecken computer scientists, together with colleagues from University College London, created "XML3DRepo". This service combines two research projects: the description language XML3D and 3D Repo, a version control system for 3D models. These make it possible to save 3D objects, change them and administer changes automatically. The project is sponsored in part by Arup.
The scene description language XML3D, developed by Sons, provides the representation in a web browser. "Through XML3D the complete model of King's Cross can be loaded in a browser and displayed on any web-enabled device," adds Philipp Slusallek, Professor of Computer Graphics at Saarland University who is also a scientific director at DFKI and the Intel Visual Computing Institute. XML3D makes this possible by enhancing the recent web standard HTML5 with the necessary elements to describe not only text, images and videos on a website but also animated and interactive 3D objects. "Thus, all 3D components are part of the HTML code which defines the website. It can be completed with further notes or planning details by any web developer," explains Slusallek.
Engineers at Arup are convinced by the "XML3DRepo" technology. In the future, they will not only be able to simulate passenger flow and arrange the placement of CCTV cameras over the Internet, but will also be able to create realistic visualizations for the public. As the Foresight, Research & Innovation group at Arup writes on its website: "Built Environment Modeling (BEM) offers excellent opportunities to make meaningful stakeholder and public engagement not only possible but also cost effective."
Vertex Modelling, a London based company building the most accurate and detailed 3D model of London, will be also featured in XML3DRepo. The model stretches across a variety of urban landscapes from the new skyscrapers in the City of London and Tower Bridge to residential houses in the boroughs of Chelsea and Knightsbridge along with a variety of London's well known and iconic landmarks.
Kristian Sons believes in the potential of XML3DRepo. He plans to commercialize the software through a spin-off with his research colleague Jozef Dobos from University College London.

Air Force aircraft returned from Vietnam is postwar source of Agent Orange contamination
2014-02-25
February 25, 2014 -- From 1971-1982, Air Force reservists, who flew in 34 dioxin-contaminated aircraft used to spray Agent Orange and returned to the U.S. following discontinuation of the herbicide spraying operations in the Vietnam War, were exposed to greater levels of dioxin than previously acknowledged, according to a study published today in Environmental Research by senior author Jeanne Mager Stellman, PhD, professor emerita at the Mailman School of Public Health's Department of Health Policy and Management.

New clues found to preventing lung transplant rejection
2014-02-25
Organ transplant patients routinely receive drugs that stop their immune systems from attacking newly implanted hearts, livers, kidneys or lungs, which the body sees as foreign.
But new research at Washington University School of Medicine in St. Louis suggests that broadly dampening the immune response, long considered crucial to transplant success, may encourage lung transplant rejection.
In a surprising discovery, the researchers found that newly transplanted lungs in mice were more likely to be rejected if key immune cells were missing, a situation that simulates ...
Ordinary conditioner removes head lice eggs as effectively as special products
2014-02-25
Eggs from head lice, also called nits, are incredibly difficult to remove. Female lice lay eggs directly onto strands of hair, and they cement them in place with a glue-like substance, making them hard to get rid of. In fact, the eggs are glued down so strongly that they will stay in place even after hair has been treated with pediculicides -- substances used to kill lice.
Some shampoos and conditioners that contain chemicals or special oils are marketed as nit-removal products. However, new research just published in the Journal of Medical Entomology shows that ordinary ...
Research links risky behaviors of gambling and sex
2014-02-25
February 25, 2014 -- Late adolescence is a period when many youth become involved in high-risk behaviors with adverse consequences. Researchers at the Mailman School of Public Health with colleagues at Johns Hopkins University studied the degree to which two such behaviors, adolescent sexual behaviors and gambling, affected African American youth in nine primary schools in Baltimore, MD. In data collected from a cohort study, they assessed whether certain adolescent sexual behaviors linked with unintended consequences such as adolescent pregnancy and sexually transmitted ...
Dartmouth-led research shows temperature, not snowfall, driving tropical glacier size
2014-02-25
Temperature, not snowfall, has been driving the fluctuating size of Peru's Quelccaya Ice Cap, whose dramatic shrinkage in recent decades has made it a symbol for global climate change, a Dartmouth-led study shows.
The findings support many scientists' suspicions that tropical glaciers are rapidly shrinking because of a warming climate, and will help scientists to better understand the natural variability of past and modern climate and to refine models that predict tropical glaciers' response to future climate change.
The study appears in the journal Geology. A PDF ...
PFC exposure may spark metabolic changes in overweight children
2014-02-25
Washington, DC—Overweight children who were exposed to higher levels of perfluorinated chemicals tended to show early signs of developing the metabolic syndrome, according to a new study published in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
The term metabolic syndrome describes a cluster of risk factors that increase the chances of developing heart disease, stroke and diabetes. The study is the first to find changing metabolic markers in children were associated with exposure to perfluorinated chemicals (PFCs), common industrial chemicals ...
Vitamin D deficiency may compromise immune function
2014-02-25
Washington, DC—Older individuals who are vitamin D deficient also tend to have compromised immune function, according to new research accepted for publication in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Vitamin D plays an important role in helping the body absorb calcium needed for healthy bones. The skin naturally produces vitamin D when it is exposed to sunlight. People also obtain smaller amounts of the vitamin through foods, such as milk fortified with vitamin D. More than 1 billion people worldwide are estimated to have deficient ...
Tissue repair drug helps heal diabetic foot ulcers
2014-02-25
Washington, DC—Patients were twice as likely to have a diabetic foot ulcer heal within eight weeks when they were treated with a tissue repair drug versus a placebo, according to new research accepted for publication in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Foot ulcers are a common complication from diabetes than can lead to hospitalization and lower limb amputation. In 2006, about 65,700 non-traumatic lower-limb amputations were performed in people with diabetes, according to the Centers for Disease Control and Prevention. Up ...
New study presents evidence that blood pressure should be measured in both arms
2014-02-25
Philadelphia, PA, February 25, 2014 – As heart disease continues to be one of the leading causes of death in the United States, practitioners and patients alike are looking for ways to cut risk factors and identify new clues to assist with early detection. New research published in the March issue of The American Journal of Medicine suggests that there is an association between a difference in interarm systolic blood pressure and a significant increased risk for future cardiovascular events, leading researchers to recommend expanded clinical use of interarm blood pressure ...
Ecotoxicity: All clear for silver nanoparticles?
2014-02-25
It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how the organisms deal with this kind of stress. To learn more about the cellular processes that occur in the cells, scientists from the Aquatic Research Institute, Eawag, subjected algae to a range of silver concentrations.
In the past, silver mostly found its way into the environment in the vicinity of silver mines or via wastewater emanating from the ...
