Disturbance Field

1—If N, E. and Z (vertical) are the three rectangular components of the earth's magnetic field, a study of the behaviour of the changes ΔN, ΔE, and ΔZ produced in them by a perturbing field gives information about the corresponding changes in this field and therefore in the overhead current system to which the field is due. In this enquiry ΔN, ΔE, ΔZ will be regarded as departures for 60-minute intervals from an undisturbed condition which is taken to be the corresponding departure on quiet days. It will be understood that this procedure assumes that the effect of disturbance on the earth’s field is to overlay quiet conditions by an additional system of forces. Average diurnal variations on both quiet, q , and disturbed, d , days were therefore formed for N, E, and Z, starting from the published hourly values of the primary horizontal elements H and D where necessary. With the two sets of variations converted into departures from their respective means, difference departures Δ d — Δ q for N, E, and Z were formed hour-by-hour to give 24 disturbance field component vectors. This was done for the seasons separately and the year as a whole for each of the observatories in Table I. In discussing the average features of regular disturbance there are advantages in using as extensive series of data as possible. Even when the five internationally selected d and q days per month are used, as in the present enquiry, exceptional isolated disturbances may obscure normal behaviour. This is especially true when the study concerns stations representing transition zones in the phenomena of disturbance. The inclusion of Fort Rae, the British Polar Year station in N. W. Canada, will, however, be seen to be fully warranted, not because of the scale of disturbance there but because of its instructive position on the polar side of the line over which the current system producing the main features of the regular daily variation of disturbance is mainly concentrated.

A single program has been developed to ensure that the final result of the data processing of the measurement calibration protocol is obtained under normal conditions. The calibration result contains a calibration function or a correction function in the form of a continuous sedate series and a calibration chart based on typical additive error probabilities. Solved the problem of the statistical treatment of the calibration protocol measuring in normal conditions within a single program “MMI–calibration 3.0” that includes identification of the calibration function in a continuous power series of indications of a measuring instrument and chart calibration. An example of solving the problem of calibration of the thermometer by the working standard of the 3rd grade with the help of the “MMI-calibration 3.0” program.

Achievable Accuracy

The analysis of a new class of measuring instrument for heat quantities based on the use of multi-valued measures of heat conductivity of solids. For example, measuring thermal conductivity of solids shown the fallacy of the proposed approach and the illegality of the use of the principle of ambiguity to intensive thermal quantities. As a proof of the error of the approach, the relations for the thermal conductivities of the component elements of a heat pump that implements a multi-valued measure of thermal conductivity are given, and the limiting cases are considered. In two ways, it is established that the thermal conductivity of the specified measure does not depend on the value of the supplied heat flow. It is shown that the declared accuracy of the thermal conductivity measurement method does not correspond to the actual achievable accuracy values and the standard for the unit of surface heat flux density GET 172-2016. The estimation of the currently achievable accuracy of measuring the thermal conductivity of solids is given. The directions of further research and possible solutions to the problem are given.

The scale is usually used to check and determine the value of a qualitative factor in quantitative measures. The measurement scale is a management in agreement that is used as a reference to determine the short length of the interval that is in the measuring instrument, so that the measuring instrument when used in measurements will produce quantitative data. The results of the scale management calculation must be interpreted carefully because in addition to producing a rough picture, the respondent's answers are not just straightforward to be trusted. Types of measurement scales: Likert scale, Guttman scale, semantic differential scale, rating scale, Thurstone scale, Borgadus scale, and various other measurement management scales. One of the most difficult jobs for information technology researchers faced with the necessity of measuring variables is: finding directions in the midst of many existing sizes. If there is a good size for a particular variable, it seems that there are not many reasons to compile a new size yourself. Keywords: Scale, Measurement, Variables.

The background of this research is an instrument of learning for reading comprehension which in general is still dominated by an instrument in the form of print out which makes the students’ interest to read is reduced. In addition, this instrument is usually done manually or handwritten so that the students’ work must be corrected manually and require some time to get the results. This study aims to develop instruments or measuring devices for reading comprehension in the Primary School in Pekanbaru and find out the feasibility of measuring devices for reading comprehension skills. This product is Macromedia Flash 8 based namely "MaCaMi" which stands forMari Membaca dan Memahami. The research method used was the 4D model with four stages, such as the define stage, the design phase, the develop phase, and the dessiminate stage which is limited to the third stage. The data of this study were obtained from product design expert validation questionnaire, questionnaire validated by linguists, teacher response questionnaire and students response questionnaire. The data were generated quantitatively and analyzed by using the assessment criteria to determine the product quality. The results of this study showed the assessment of product design experts in draft 1 had an average percentage of 69.61% with the appropriate category then had increased in draft 2 to 90.56% with the very feasible category. The results of  the feasibility test by linguists in draft 1 with had average percentage of 95.30% with the very feasible category then increased in draft 2 to 97.20% withn the very feasible category. The results of the teacher's response to the reading comprehension measuring instrument in the Primary School in Pekanbaru developed by researchers obtained an average percentage of 93.50% with a very good category and the results of students' responses to the measuring instrument obtained an average percentage of 89.90% with a category very good. Based on these results, it can be concluded that the product developed by researchers is feasible to be used as a measure of reading comprehension ability of primary school students.

Similarities And Differences

The interface between tourism and built heritage is complicated because much built heritage is located in the middle of living communities. Questions arise about how to achieve a balance between the expectations of tourists and the community. To study this question, this paper reports on tourists’ and residents’ impressions of an international heritage tourism site, the Kampong Taman Sari in Indonesia. Using a linear-numeric semantic differential as the measuring instrument and nine consensus photographs of the site as stimuli, the study investigated similarities and differences in impressions between three groups: tourists (international and domestic) and residents. Three principal dimensions were found to underlie impressions of the site: Attractiveness, Organisation, and Novelty. Significant differences were found among all three groups in their impressions of Attractiveness. In terms of impressions of the Organisation of the site, international and domestic tourists have similar impressions but these differ significantly from the impressions of residents. On the other hand, domestic tourists and residents have similar impressions of the Novelty of the site, which is evaluated differently by international tourists.
