Cloud computing is a major technology enabler for providing efficient services at affordable costs by reducing the costs of traditional software and hardware licensing models. As it continues to evolve, it is widely being adopted by healthcare organisations. But hosting healthcare solutions on cloud is challenging in terms of security and privacy of health data. To address these challenges and to provide security and privacy to health data on the cloud, the authors present a Software-as-a-Service (SaaS) application with a data model with built-in security and privacy. This data model enhances security and privacy of the data by attaching security levels in the data itself expressed in the form of XML instead of relying entirely on application level access controls. They also present the performance evaluation of their application using this data model with different scaling indicators. To further investigate the adoption of IT and cloud computing in Indian healthcare industry they have done a survey of some major hospitals in India.

The article is devoted to the positioning of modern approaches, concepts and models to the complex issues of the development of automated systems and their support throughout the life cycle. The topic is relevant for the creators of modern computer graphics software and hardware complexes and software-hardware complexes at the stages of their design and support. A hierarchy of universal concepts for building software and hardware is described in the paper. The first level consists of the concept of system intellectualization, the concept of software and hardware globalization, the systems concept, the concept of the support for systems during the life cycle, the concept of open systems, the object-oriented approach, and others and etcetera. The second level consists of the concept of the situation approach, the scenario approach, the scenario-situational approach, the logistics approach, the multi-agent approach, and etcetera. The third level of the hierarchy consists of the concept of abstraction hierarchies, the concept of aggregations, the concept of generalizations (DB), the concept of normalizations, the concept of semantic networks, the concept of frame networks, the concept of multimedia frame networks (remote control and monitoring systems), the concept of networks of frames with fuzzy logic and etcetera. The article is based on works in the field of system analysis, ACS, CAD and knowledge representation systems and artificial intelligence.

<span>In the high-tech world, medical imaging is very important to diagnose and analyze illness inside human body. The increasing number of patients annually has continuously growth the amount of medical imaging data generated and directly causes a demand for data storage. Generally, medical images are rich with data, where these data are important for diagnosing purpose. However, some of the data represents redundant information and sometimes can be discarded. Thus, the research area on medical image compression dealing with three-dimensional (3-D) modalities need to be given more attention and exploration. The algorithm development using wavelet transform with software implementation are the famous topics explored among researchers, whilst fewer works have been done in utilizing curvelet transform in medical image compression. Along with that, very limited hardware implementation of 3-D medical image compression is discovered. In term of performance evaluation, most of the previous works conducted objective test compared with subjective test. To fill in this gap, medical image compression system will be reviewed, with the aim to identify the recent method used in medical image compression system. This paper thoroughly scrutinizes the recent advances in medical image compression mainly in terms of compression method, algorithm development with software and hardware implementations and performance evaluation. In conclusion, the overall picture of the medical image compression landscape, where most of the researchers more focused on algorithm development or software implementations without having the combination of software and hardware implementations.</span>

This paper is devoted to the development of the ontology-driven standalone scientific visualization station based on a single-board microcomputer with custom tangible user interface. Such a station can be used as a powerful demonstration tool in various scenarios including interactive museum exhibitions. According to the approach proposed, the particular instance of a software scientific visualization system is generated automatically by a high-level platform SciVi that was been developed earlier. Previously, ontology-driven software generation mechanisms within SciVi were tested on the firmware generation for the microcontroller units. Currently we present a generalization of this technique to the case of systems on chips like Raspberry Pi or Orange Pi. Data preprocessing and rendering capabilities of SciVi are reused without modifications from the previous stages of development, while the new mechanisms of taking into account the specifics of systems on chips software and hardware organization are introduced via extending the appropriate SciVi ontologies. The generalized technique is tested in practice by creating a set of interactive museum items for the “Transmutations” exhibition within Kidsmuseum, branch of Perm Regional Museum.

Insight Into

Geological samples typically contain many minerals (phases) with multiple element compositions. A complete analytical description should give the number of phases present, the volume occupied by each phase in the bulk sample, the average and range of composition of each phase, and the bulk composition of the sample. A practical approach to providing such a complete description is from quantitative analysis of multi-elemental x-ray images.With the advances in recent years in the speed and storage capabilities of laboratory computers, large quantities of data can be efficiently manipulated. Commercial software and hardware presently available allow simultaneous collection of multiple x-ray images from a sample (up to 16 for the Kevex Delta system). Thus, high resolution x-ray images of the majority of the detectable elements in a sample can be collected. The use of statistical techniques, including principal component analysis (PCA), can provide insight into mineral phase composition and the distribution of minerals within a sample.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.
