Analysis of Fast Initialization for Vectored Wireline Systems

Cooperation of transceivers on signal level at the remote terminal—often referred to as vectoring—is an effective approach to mitigate crosstalk in wireline transmission systems. While the gain in bitrate compared to crosstalk-limited transmis- sion is substantial, the initialization of a vectoring system requires time and care to ensure system stability. In this contribution, a fast initializatio

Critique of the Danish 911 "truth" movement, based on observations at a public meeting where Niels Harrit, a Danish chemistry professor, promotes the theory of "controlled demolition" of the World Trade Center building 7, WTC7. A critique of a prominent conspiracy theory, published in a Danish weekly news magazine.

IR in Software Traceability: From a Bird's Eye View

Several researchers have proposed creating after-the-fact structure among software artifacts using trace recovery based on Information Retrieval (IR). Due to significant variation points in previous studies, results are not easily aggregated. Aim. We aim at an overview picture of the outcome of previous evaluations. Method. Based on a systematic mapping study, we perform a synthesis of published r

Extensions to an Optimization-Based Multivariable Reduction Method

In this paper two extensions to an optimization based model reduction method are considered: frequency-weighted and parameter-dependent model reduction. The performed extensions are simple and natural, this fact illustrates the advantages of the method. Also, the methods may be applied using an exact model or frequency samples ofa model. We construct numerical examples to illustrate both extension

Motivational Triggers in Projects: A Comparative Study of the Construction and Consulting Industries

The existence or absence of motivation among project members can determine whether or not a project succeeds or fails. Establishing and maintaining motivation, however, are difficult tasks for project managers. Individuals have different triggers of motivation and it is a complex task to understand the underlying motivational drivers of every member of a project, especially because projects are ch

Increasing DG Capacity of Existing Networks through Reactive Power Control and Curtailment

Renewable energy sources (RES), especially wind turbines, have become more important during the last years. An increasing number of distributed generation (DG) units are connected to weak medium voltage distribution networks in rural areas where they have a large influence on the voltage and the line losses. Voltage rise is in this case often a limiting factor for the maximum amount of DG capacity
