Data Reduction. Data from measurements made as part of the ETV test will be reported as emissions rates in grams/kilowatt hour (grams/brake horsepower) and as percentage emission reductions from the baseline engine. Emissions specific to a particular technology (e.g. ammonia) may be reported in units of concentration as well as grams/kilowatt hour (grams/brake horsepower). The confidence limits will be presented as well as the mean emissions reduction, as discussed in Section 5.1.2. When they would be helpful to the mobile sources community because of established usage, the appropriate English engineering units will be supplied parenthetically.
Data Reduction. (a) The data from each brake application prescribed in paragraph 3.(e) above is filtered using a five-point, on-centre moving average for each data channel.
Data Reduction. Data from measurements for NOx from the verification test will be reported in: • Parts per million by volume (ppmv), and • ppmv corrected to 15 percent O2. One-minute average NOx concentration values will be recorded by Labtech Notebook. Test run averages will be calculated from the valid readings at each of the eight traverse points.

Data Reduction. Raw data will be collected for each one-hour test period and averaged. Data reduction periods will not exceed one hour to minimize the impact of varying ambient conditions. Test calculations will be performed on a one-hour basis. Some raw data may include corrections for instrument laboratory calibration data if the corrections can be performed automatically in the DCS or DAS.
Data Reduction. The method of selecting, focusing, simplifying, abstracting, and transforming the data that appear in written-up field notes or transcriptions is known as data reduction. To reduce the amount of data significantly, it must first be structured. In this instance, a written transcript was created using the information from the observation and interview. The transcript was then examined to identify the utterances that were thought to exhibit the cod-mixing phenomenon and those that were not. The researcher made a video recording during the learning process carried out by the teachers in the classroom, then the researcher transcribed it into written form to make it easier for researchers to analyze the data.
Data Reduction. Available published information and site‐specific data from the selected site will be compiled for inclusion in the Detailed Study and will be consistent with the information needed for the Engineering Report as required for permitting land application systems under the Florida Water Reuse Rule (Chapter 62‐610, F.A.C.), which will be prepared under Task 3.2 of this scope of work. Compiled published and site‐specific information will include the following: Geologic information from available literature including information concerning sinkhole features within 1 mile of the selected site Identification, extent, and characterization of shallow aquifer horizons and potential aquitard (low‐ permeability) horizons underlying the selected site. Head relationships between aquifer horizons Water table elevations at the time of hydrogeologic investigation 4 WT0208161131TPA GENERAL SCOPE OF SERVICES – WETLAND GROUNDWATER RECHARGE PARK: DETAILED STUDY, DESIGN, AND PERMITTING SERVICES Water balance data from infiltration testing Estimated directions and rates of groundwater movement Information on existing water supply xxxxx (and monitoring xxxxx, as appropriate) within 1 mile of the selected site
Data Reduction. Data from measurements made as part of the ETV test will be reported as emissions rates in g/kWh (g/bhp-hr) and as percentage emission reductions from the baseline engine. The confidence limits will be presented as well as the mean emissions reduction, as discussed in Section 5.1.2. When they would be helpful to the mobile sources community because of established usage, the appropriate English Engineering units will be supplied parenthetically.
Data Reduction. Data reduction is the first phase in data analysis technique. That is the process of decreasing data that occurs on a regular basis. ―Reducing data involves summarizing, selecting the primary item, focusing on the vital things, and determining the topic and form.‖ Moleong (2006) At this stage, the researcher collects data from the result of students’ interview and observation as well. The outcome interview is selected and focus on the data reffering to the research problem based on students’ willingness to communicate in English language and what factors that affecting their willingness to communicate in English language. The unnecessary data is removed in this stage, and the necessary material is included. It is impportant for the next stage which was data display so there is no recurred data.
Data Reduction. A software module will be implemented for simplifying geometric data with textures and appearance information. The simplification will create a progressive data structure that can be saved to special file format.
