The superconducting CH multi-cell prototype cavity, which has passed a very succesfull power test recently leading to an accelerating gradient of Ea = 7 MV/m, will be equipped with a frequency tuning system [1]. The rftuning during operation bases on the principle of a slight elastic deformation at both ends of the tank. This is causing a change in the gap width of the first and last accelerati...

Planar microresonators provide a large boost of sensitivity for small samples. They can be manufactured lithographically to a wide range of target parameters. The coupler between the resonator and the microwave feedline can be integrated into this design. To optimize the coupling and to compensate manufacturing tolerances, it is sometimes desirable to have a tuning element available that can be...

The advent of the Internet alleviates the access bottleneck to TV distribution channels and softens licensing requirements. This lowers entry barriers to TV markets via the Internet in various forms. This paper takes the German TV sector as an example to analyze the attractiveness of TV markets for new entrants. A sequential framework for entering TV markets is introduced. The skills set of an ...

SET the Brazilian Society for Television Engineering has been studying the topic and has been following up closely on the work done in other countries and by ITU. In 2013, it provided the Ministry of Communications and Anatel (Brazilian Telecommunications Regulatory Agency) with extensive interaction with companies and regulators from countries as the United Kingdom, Japan, and Germany. It also...

Television has been around for many decades now and has become ubiquitous. Analog TV technology, however, which was developed before the 1940’s, has remained essentially the same over the last 50 years. Alternative digital transmission standards have been developed recently and are in use for satellite and cable transmissions. This technology is now being deployed for terrestrial TV as well. Th...

The constant flux of data and queries alike has been pushing the boundaries of data analysis systems. The increasing size of raw data files has made data loading an expensive operation that delays the data-to-insight time. Hence, recent in-situ query processing systems operate directly over raw data, alleviating the loading cost. At the same time, analytical workloads have increasing number of ...

This paper introduces a genetic tuner implemented for optimizing the image scene analysis prior to the grasping of the objects, to realize a concrete working robot named COERSU. Firstly, different architectures of the adaptive neuro-fuzzy inference system, multi-layer perceptron and K-nearest neighborhood classifiers are compared to perform scene analysis and object recognition. Following on, t...

Sparse matrix vector multiplication (SpMV) is an important kernel in scientific and engineering applications. The previous optimizations are sparse matrix format specific and expose the choice of the best format to application programmers. In this work we develop an auto-tuning framework to bridge gap between the specific optimized kernels and their general-purpose use. We propose an SpMV autot...

A broadband microwave interferometric technique for scanning near-field microscopy applications is proposed. The method is based on the association of a vector network analyzer, a hybrid coupler, an evanescent microwave coaxial probe and a precise impedance tuner built up with a high precision programmable delay line and a variable motor-driven attenuator. Advantages such as simplicity of opera...

This paper covers practical study of responses of the systems which are under control. The auto tune proportional-integral – derivative (PID) controller is used for controlling of systems. The auto tune algorithm is implemented using the successive approximation method. The auto tuner has been checked with various plant models in MATLAB environment that causes only minor perturbation on the nor...
