In medical applications wireless technologies are not widely spread. Today they are mainly used in non latency-critical applications where reliability can be guaranteed through retransmission protocols and error correction mechanisms. By using retransmission protocols within the disturbed shared wireless channel latency will increase. Therefore retransmission protocols are not sufficient for removing latency-critical wired connections within operating rooms such as foot switches. Todays research aims to improve reliability through the physical characteristics of the wireless channel by using diversity methods and more robust modulation. In this paper an Architecture for building up a reliable network is presented. The Architecture offers the possibility for devices with different reliability, latency and energy consumption requirements to participate. Furthermore reliability, latency and energy consumption are scalable for every single participant.
Economic growth is usually driven by improvements in productivity, economic efficiency, trade and innovation. Increasing efficiency means to produce larger output using the same amount of factors for production such as raw materials, labour, and capital. However, regardless of the driver, growth is often investment-hungry and it is not rare to find an economy with potential for growth but lacking locally available investment. In this scenario, Foreign Direct Investment (FDI) can fill the gap between investment needed to promote economic growth and locally available investments.
Gaps in basic math knowledge are among the biggest obstacles to a successful start in university. Students starting their studies in STEM disciplines display significant diversity, “math anxiety” is a widespread phenomenon, and the transition to a self-determined way of studying presents a huge challenge. Universities offer support measures such as preparatory courses. Over the years, Offenburg University realized that with increased diversity, traditional ways of teaching in front of the class have become inefficient. The majority of the students remained inactive and just listened to the teachers’ explanations and the few active participants’ answers.
Since 2013 our new course concept fosters a shift from teaching to active learning on a large scale, involving several hundred participants of our on-site preparatory math courses. This switch to broad active practicing, however, must go hand in hand with providing individual support for an increasingly diverse student body. Meanwhile students bring along their mobile devices, and the training App TeachMatics serves as a facilitator. The course concept has been very well received by both students and teachers.
In the past two decades much has been published on whiplash injury, yet both the confusion regarding the condition, and the medicolegal discussion about it have increased. In this paper, functional imaging research results are summarized using MRIcroGL3D visualization software and assembled in an image comprising regions of cerebral activation and deactivation.
How can manufacturers or service companies provide better services with connected products, without having acquired a powerful IT infrastructure nor the competences for software development?
Today companies can appeal to a relocated-IT-infrastructure provider, which is called Cloud.
Consequently, they do not have to manage and take care of the safety/security aspect, the updates and the breakdown of the infrastructure internally, as those are all managed by the provider.
It is possible to outsource the development of the software of the connected product to an external company. However, the question now is how fast this company can juggle from one Cloud to another in order to fulfil their clients wishes?
neverMind offers a solution based on a multi-protocols-platform linking the different connected products to a multitude of Clouds without having to redesign the whole communication stack/building block for each change in the Cloud-solution. This is the object of my thesis.
The development follows the V-Model, the first steps to understand the complexity of the project were the realisation of the product technical and architectural specifications. The last step before the Implementation was to design in details the progress and the process of every parts of the platform.
The outcome of the requirements analysis led me to divide the project in two parts:
• a “General Interface” acting as a gateway between the Client-application and “Cloud-modules”
• the “Cloud-modules” themselves.
So far, the specifications are drown up; the General Interface and a client example are coded, as well as a first Cloud-module template.
