CoolEmAll aims to increase understanding about the interaction between IT hardware, software (applications and workloads) and power/cooling systems within data centres. A number of tools, blueprints, and other resources are being developed to help data centre designers, operators, and technology suppliers, to build and run more energy efficient facilities and equipment. “Factors such as rising fuel prices, stricter environ­mental legislation and constrained credit amid the financial crisis are contributing to higher capital and operational costs for data centre owners and operators,” said Andrew Donoghue, Senior Analyst, 451 Research (part of the CoolEmAll consortium).

As the oceanographic understanding of internal waves is advanced, their role in sedimentological processes has recently become the focus of increasing attention. This study analyses a large section of modern seafloor in a region with a pronounced internal wave regime and explores different possible interpretations for the origin of observed bedforms. To this end, the seafloor geomorphology and shallow-subsurface information provided by a giant (>12,500 km²) industrial 3D seismic-reflection survey imaging the outer shelf and upper slope of the Browse Basin region on the North West Shelf of Australia is examined.

This data extract was created in support of the DHS/FEMA Challenge submission for the National Day of Civic Hacking. This file includes all fires that occurred during 2011 as reported by U.S. Fire Departments (FDs) to the NFIRS, summarized at the ZIP code level. NFIRS typically captures about three-quarters of all reported fires in the U.S. per year; the counts are for information only - analyses should be based upon the "percent" fields. To be included in this data extract, the incident report included a valid ZIP code. Accuracy of the ZIP code is dependent upon the reporting FD. ZIP codes with zero fires reported are not included in this dataset. Read More

Driven by a combination of consumer demand and the development of new information and communications technology (ICT), the world is rapidly transforming. This process, called digitization, has been happening since the arrival of the computer 60 years ago, but in the past few years it has accelerated, altering everyday life in unprecedented ways. Technological developments such as handheld devices, pervasive sensors, “big data” analytics, digital supply chains, search engines, social
networks, satellite-based geographic tracking, interconnected real-time digital infrastructure, and massive server farms have fundamentally altered our society. Read More

Geography implies movement particularly when spatial data have a temporal component. Macro-economical data present such a sort of information as imports and exports from origin to destination create moving tracks. We know these trajectories for instance from the tracks of ships on the oceans. MIT Media Lab worked on a tool that allows composing a visual tale about countries and products they exchange (import/export). It provides five different kinds of visualisation, which can be the traditional presentation of geographic data as choropleth maps but also proportional illustrations of good exchange between countries that allow a sensation of thematic scale. The open source tool is called the Observatory of Economic Complexity and uses bilateral data of roughly 200 countries, 50 years and around 1000 different products. Read More

Recent years have witnessed a growing interest in understanding the semantics of point clouds in a wide variety of applications. However, point cloud labeling remains an open problem, due to the difficulty in acquiring sufficient 3D point labels towards training effective classifiers. In this paper, we overcome this challenge by utilizing the existing massive 2D semantic labeled datasets from decadelong community efforts, such as ImageNet and LabelMe,and a novel “cross-domain” label propagation approach.
Our proposed method consists of two major novel components, Exemplar SVM based label propagation, which effectively addresses the cross-domain issue, and a graphical model based contextual refinement incorporating 3D constraints. Most importantly, the entire process does not require any training data from the target scenes, also with good scalability towards large scale applications. We evaluate our approach on the well-known Cornell Point Cloud Dataset, achieving much greater efficiency and comparable accuracy even without any 3D training data. Our approach shows further major gains in accuracy when the training
data from the target scenes is used, outperforming state-ofthe-art approaches with far better efficiency. Read More

Energy and communication networks are in today's urban environment ubiquitous and are highly dynamic  infrastructures. It is important for these networks to quickly respond to changes and adapt the parameters in order to be able to strive for the best possible utilization and also to satisfy the needs of the user. The aim of this paper is to show the influence of intelligent networks on users, and the integration of information via smart platforms in everyday life is examined. Smart power grids and control systems for Electric Mobility will be used as examples.

This is the final post in the series titled AutoCAD Map 3D API Training content.The previous posts are: Part-1 , Part 2, Part-3, Part-4 and Part-5. In this post, I will talk about the API for creating and managing Map Layers. There are two basic Map 3D .NET types that will help you manage your Map and Map Layers: AcMapMap and AcMapLayer. AcMapMap represents the conceptual container that contains your Map data. Put another way, it contains all the geospatial layers representing your map data. AcMapLayer represents the geospatial layer itself: Read More

It has not been very long since three-dimensional (3D) was introduced in Nepal. The use of animation has increased and within a short span of time‚ started getting acclaims. But why is 3D garnering so much interest? According to James Cameroon‚ a veteran animated movie maker‚ “3D means the feel of reality and 3D is possible in entertainment. It is the blend of entertainment industry that makes the outside world feel quite real.” The 3D animations have become the world’s most demanded art. The areas of 3D animation are films‚ computer games‚ and advertisements. Read More

This blog post can be seen as a sequel to a former blog post on the introduction on geospatial data sharing and spatial data infrastructures (SDI), where I explained the basics of OGC standards and web services. Quite some research organisations and governmental agencies already employ OGC standards to make data available online, often even free of charge for the public. I would like to present some really good examples of interoperable data sharing in New Zealand.

China is stepping up its use of remote sensing technology and will analyze data from satellites sent into orbit to get more comprehensive and accurate information about its air pollution, according to scientists attending the ongoing 35^th International Symposium on Remote Sensing of Environment in Beijing. The satellites have been sent by China, the U.S. and Europe. Li Zhengqiang, a researcher with the Institute of Remote Sensing and Digital Earth of the Chinese Academy of Sciences, says, "The new satellite Gaofen-1 is the first one of China's high-resolution system for earth observation. And one of its purposes is to monitor air pollution." The country plans to launch five or six such kinds of satellites before the end of 2015. Read More

Light detection and ranging (LiDAR), also known as airborne laser scanning, is a rapidly emerging technology for remote sensing. Used to help map, monitor, and assess natural resources, LiDAR data were first embraced by forestry professionals in Scandinavia as a tool for conducting forest inventories in the mid to late 1990s. Thus early LiDAR theory and applications were developed for commercial forests typical of a region with gentle topography; conditions far different from those of the temperate rain forests of the Pacific Northwest.
