… powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic …
… silencer based on active noise control is to improve the reduction of the low frequency noise below 250 Hz. In this project we also have a passive component that reduce the higher frequencies. The active control system should make the system better in the low frequency range …
… possibility to have those kinds of damages is 29 % and 12 % when the damage frequency is at least 1 % of the main stems. Also three objects with a lot of damages reported by the forest owner were investigated with the same method. They have much higher frequency of damages, 39 …
… to evaluate. To evaluate these problems we used different kinds of methods. A frequency study was made on the internal forklift. For that we used a predefined sheet where we once a minute registered what it were doing. With a stopwatch we registered how long time the operators …
… att förklara vad som påverkar svenska B2C-företags beslut att utnyttja Radio Frequency Identification (RFID) som identifieringsteknik för att personliggöra kundrelationer inom sina lojalitetsprogram. Studien utfördes som en fallstudie då vi undersökte hur två stora svenska …
… is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of …
… Studies have shown that whole body vibration exercise with low amplitude and frequency has effects like alleviation of pain, increased movement and muscle strength. The aim of this study was to see if strength training on an Xrsize vibration plate has an effect on muscle …
… starts with an electrical signal that consists of a square wave with a varied frequency. The signal converts via the software to become a PWM-signal that has a fixed frequency. A low pass filter and a differential amplifier make the signal meet the interface of AK95S. Results …
… calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated …
… after 45 minutes from start. Physiological parameters (blood pressure, heart frequency and skin temperature) and behaviour/emotional status were registered on horses and humans before and after 2 and 4 minutes after the active treatment and 15, 25 and 45 minutes after the active …
… Transform) of the signal from the microphones. It means that the signals frequency’s domain is showed, in other word it shows which frequency components a signal has. Then the result is showed online by a function belonging to LabVIEW which is called Web Publish. In second part …
… called flicker, seem to be generated by the Stirling micro cooler since the frequency of the flicker follows the frequency of the cooler. The cause of this flicker is unknown despite numerous of studies. The goal concerning the noise was to do studies in order to confirm or …
En samtalsanalytisk studie
… conversation analysis. A number of phenomena of interest were identified. The frequency of occurence of some of these phenomena was calculated to complement the qualitative analysis. The results show a number of phenomena occurring where mutualunderstanding is present and when …
