Aim of the paper is the demonstration of a paradigm shift in shape, color and spectral measurements in industry, biology and medicine as well as in measurement education and training. Innovative hardware apps (hwapps) and software apps (swapps) with smartpads are fundamental enablers for the transformation from conventional stationary working places towards innovative mobile working places with in-field measurements and point-of-care (POC) diagnostics. mobile open online courses (MOOCs) are transforming the study habits. Practical examples for the application of innovative photonic micro shapemeters, colormeters and spectrometers will be given. The innovative approach opens so far untapped enormous markets for measurement science, engineering and training. These innovative working conditions will be fast accepted due to their convenience, reliability and affordability. A highly visible advantage of smartpads is the huge number of their distribution, their worldwide connectivity via Internet and cloud services, the standardized interfaces like USB and HDMI and the experienced capabilities of their users for practical operations, learned with their private smartpads.

IT security and computer forensics are important components in the information technology. From year to year, incidents and crimes increase that target IT systems or were done with their help. More and more companies and authorities have security problems in their own IT infrastructure. To respond to these incidents professionally, it is important to have well trained staff. The fact that many agencies and companies work with very sensitive data make it necessary to further train the own employees in the field of network forensics and penetration testing. Motivated by these facts, this paper - a continuation of a paper of January 2012 [ 1], which showed the conception of a course for professional training and education in the field of computer and mobile forensics - addresses the practical implementation important relationships of network forensic and penetration testing.

Streaming media is a recent technique for delivering multimedia information from a source provider to an end-user over the Internet. The major advantage of this technique is that the media player can start playing a multimedia file even before the entire file is transmitted. Most streaming media applications are currently implemented based on the client-server architecture, where a server system hosts the media file and a client system connects to this server system to download the file. Although the client-server architecture is successful in many situations, it may not be ideal to rely on such a system to provide the streaming service as users may be required to register an account using personal information in order to use the service. This is troublesome if a user wishes to watch a movie simultaneously while interacting with a friend in another part of the world over the Internet. In this paper, we describe a new real-time media streaming application implemented on a peer-to-peer (P2P) architecture in order to overcome these challenges within a mobile environment. When using the peer-to-peer architecture, streaming media is shared directly between end-users, called peers, with minimal or no reliance on a dedicated server. Based on the proposed software rho epsilon nu mu alpha (pronounced [revma]), named for the Greek word meaning stream, we can host a media file on any computer and directly stream it to a connected partner. To accomplish this, rho epsilon nu mu alpha utilizes the *** Framework and Windows Presentation Framework, which are widely available on various types of windows-compatible personal computers and mobiledevices. With specially designed multi-threaded algorithms, the application can stream HD video at speeds upwards of 20 Mbps using the User Datagram Protocol (UDP). Streaming and playback are handled using synchronized threads that communicate with one another once a connection is established. Alteration of playback, such as pausing

High Efficiency Video Coding (HEVC), the latest video compression standard ( also known as H. 265), can deliver video streams of comparable quality to the current H. 264 Advanced Video Coding (H.264/AVC) standard with a 50% reduction in bandwidth. Research into SHVC, the scalable extension to the HEVC standard, is still in its infancy. One important area for investigation is whether, given the greater compression ratio of HEVC ( and SHVC), the loss of packets containing video content will have a greater impact on the quality of delivered video than is the case with H.264/AVC or its scalable extension H.264/SVC. In this work we empirically evaluate the layer-based, in-network adaptation of video streams encoded using SHVC in situations where dynamically changing bandwidths and datagram loss ratios require the real-time adaptation of video streams.

Many chronic diseases, including obesity and cancer, are related to diet. Such diseases may be prevented and/or successfully treated by accurately monitoring and assessing food and beverage intakes. Existing dietary assessment methods such as the 24-hour dietary recall and the food frequency questionnaire, are burdensome and not generally accurate. In this paper, we present a user interface for a mobile telephone food record that relies on taking images, using the built-in camera, as the primary method of recording. We describe the design and implementation of this user interface while stressing the solutions we devised to meet the requirements imposed by the image analysis process, yet keeping the user interface easy to use.

Recently, mobileapplications which provide health services at anytime and anywhere are on demand due to the growth of mobile wireless technologies. For the health service, an inspection service middleware is needed for monitoring health condition such as observing and analyzing EEG (electroencephalography), ECG (electrocardiography) and EMG (Electrocardiogram) waveforms from wearable ECG devices under the coverage of a wireless sensor network (WSN). For the inspection service middleware, we propose a new notion of prediction model based on risk ratio Expectation Maximization (EM) by monitoring real-time bio-signals. The prediction model can detect abnormal health condition by the monitoring system. In this paper, we explain the detail algorithms and results for these steps based on EM. There are the five modules as follows: (1) The measurement of bio-signals such as body temperature, EEG, ECG and EMG, (2) Object assessment from measurement wavelength, (3) Situation assessment from GPS in smart device, (4) Maximized health condition using risk ratio EM, (5) Knowledge update and decision making for healthy life.

Energy is a precious resource and as electronic devices (e.g., tablets, smart phones, Internet-connected appliances) and electric cars become ubiquitous, the demand for energy will continue to increase. To meet this demand and enable the integration of renewable resources, electrical distribution networks are beginning to adopt smart-grid technologies by providing bidirectional communication between the distribution grid and the electric meter. The question of how appliances within the home will interface with the smart-grid is still an open question. We propose to use wireless sensor networks as a platform to enable detailed household monitoring, demand response, load scheduling, occupancy-based control, intelligent lighting, and other general-purpose control strategies. In this vision, the smart-grid interface is a single input to the building control system which consists of a wide variety of other sensors and supports many applications that greatly extend the capabilities of the smart-grid. To explore this concept we have: developed efficient and accurate energy disaggregation algorithms, developed reliable multicast and broadcast network protocols, evaluated 10 strategies for energy savings, designed a WSN-based building monitoring and control platform, and evaluated this approach in both offices and a residential home.
