Egen formulering, plagiat eller kopia. Hur höjer vi ribban för vad studenten anser vara fusk?

Fusk och plagiat är något av en ödesfråga för den högre utbildningen. Om studenter klarar sig igenom kurser på grund av fusk hotas allmänhetens och arbetsgivarnas förtroende för den högre utbildningen. Tyvärr råder det idag en avsevärd oenighet om var gränsen för fusk går. Vi anser det därför vara hög tid att vi som lärare tar vårt ansvar och diskuterar dessa frågor ingående samt ger tips till var

Robust Narrow-Band Disturbance Rejection Using Overparameterized Pole-Assignment Control

In this work the problem of designing feedback controllers for the rejection of narrow-band disturbances is considered. The design technique proposed herein is based upon a well-suited overparameterization of a standard model-based minimum-variance controller; the extra-degrees-of-freedom so introduced are used to improve the performence of the basic controller. In particular, the problem of impro

Species and epitope specificity of two 65 kDa glutamate decarboxylase time-resolved fluorometric immunoassays.

The 65 kDa isoform of human glutamate decarboxylase (GAD65) is a major autoantigen in type 1 diabetes (T1D). In the present study, we have developed a sensitive sandwich time-resolved fluorescence immunoassay (TRFIA) for the quantification of GAD65 in cell extracts, cell media and serum. The monoclonal antibody GAD-6 is used to selectively capture GAD65 but not the slightly larger isoform GAD67, a

Automatic Tuning of Digital Controllers with Applications to HVAC Plants

It has been demonstrated that PID controllers can be tuned effectively based on an experiment with relay feedback. This paper describes a tuning method for a general digital controller based on relay feedback. The control design method is based on pole placement. An interesting feature is that the sampling period and the desired closed-loop poles are determined from the experiment. The method is a

Process and Control Design for a Novel Chemical Heat Exchange Reactor

A new chemical reactor, the Open Plate Reactor (OPR), is being developed by Alfa Laval AB. It has a very flexible configuration with distributed inlet ports, cooling zones and internal sensors. This gives the OPR improved control capabilities compared to standard chemical reactors in addition to better heat transfer capacity. In this paper, we address the relationship between the process design,
