    Experiential Learning in Daylighting Course through Performance Measurements
    (İstanbul Gelişim Üniversitesi / Istanbul Gelisim University, 2023) Yıldırım, Semih Göksel; Baur, Stuart W.; Yarbrough, Thomas G.; Nieters, Matthew
    The main objective of this study is to adapt research studies on performance measurements for daylighting design to education. An experimental course has been introduced in Missouri University of Science and Technology, and the curriculum was developed by including active learning beside the traditional learning environment. The parameters used in the schematic design and design development stages are presented, and the curriculum topics and practical experience are explained in the study. Particularly performance measurements are associated with course assignments. Curriculum results are evaluated qualitatively with assignment results and quantitatively with surveys. Current and emerging metrics are included in lab assignments and results of course assessments show that emerging metrics in daylighting technology and practical experience had attraction over participants. As a result of the evaluation of two sample courses, differences emerge regarding the courses that can be given at undergraduate and graduate levels. These differences are grouped into traditional lecture learning environments and experiential learning environments. The learning outcomes of the course curricula are summarized as gaining the knowledge and skills to communicate technically at the level of design practitioner for the student aiming for undergraduate graduation and at the level of the research community for the student aiming for graduate level.

    Effect of Vertical Elastic Design Spectral Obtained According to Different Soil Classes on Beam Behavior and Comparison of Vertical Component of K.Maras Earthquake with Beam Effect
    (İstanbul Gelişim Üniversitesi / Istanbul Gelisim University, 2023) Şahin, Furkan; Araslı, Ersen
    In practice and theory, many types of reinforced concrete slabs are used, such as beamed, beamless, and ribbed slabs. Beamed floors are connected to the columns by means of beams, and their vertical and horizontal loads are transferred to the columns through these beams. Therefore, beams are accepted as an important structural element by earthquake experts and many formulas and approaches have been developed in terms of horizontal and vertical load effects that occur in order to transfer the load transfer to the elements as desired. In this study, beam shear forces that occur under the influence of vertical earthquakes at the i and j ends of the beams of a fictional building whose floors are modeled according to the rigid diaphragm assumption in the ETABS were investigated. In this study, the shear forces that occur in the beams of a fictionally designed building under the effect of vertical earthquakes, and the floors carried by the beams are examined by designing with the assumption of a rigid diaphragm. The structure is designed with 3 openings in the X and Y directions and each opening is equal and 5 m. The 5-storey building has been designed to have equal floor heights of 3 m. The structure was obtained by using parameters belonging to 5 different soil classes as ZA, ZB, ZC, ZD, ZE, and 5 different vertical elastic design spectrums represented by the abbreviations EZ_ZA, EZ_ZB, EZ_ZC, EZ_ZD were activated in the ETABS. Seismic station coordinates numbered 4631 in K.Maras/Elbistan were used to obtain the parameters to be used in obtaining the vertical elastic design spectral of the structure. These coordinates were selected in order to compare the i and j end shear forces of the beam with the previously obtained beam i and j ends shear forces by influencing the Mw:7.6 Elbistan earthquake recorded by the seismic station to the building. Since the structure is symmetrical in both X and Y directions, the results obtained from beams B2, B3, B5, B19 represent the beam shear forces occurring at the i and j ends of all beams of the structure. As a result, it has been seen that the highest values of beam i and j end shear forces, obtained by affecting both the vertical elastic design spectral and the data of the vertical component of the Elbistan Mw:7.6 earthquake, were obtained on the 5th floor, which is the top floor of the building. The structure showed similar behavior among the different vertical elastic design spectral, and the highest value was obtained for each vertical elastic design spectrum at the 5th floor. Among these vertical elastic design spectral, the EZ_ZC spectrum gave the highest value at the 5th floor of the building. When the EZ_ZC vertical elastic design spectrum beam i and j end shear forces are compared with the beam i and j end shear forces of the vertical component data of the Elbistan Mw:7.6 earthquake, it is seen that the difference is not significant. It has been seen that the beam i and j end shear force value of the spectrum is higher than the shear force value.

    Analysis of Relatively Short Variable Rate “Noisy” Well Test Data Using Non-Linear Deconvolution
    (İstanbul Gelişim Üniversitesi / Istanbul Gelisim University, 2023) Onaiwu, Oduwa David; Ikponmwosa, Usiosefe Benedict
    Short well test data are pressure-rate-time data that are not long enough to be used to infer the reservoir boundary model and are very common in the oil and gas industry. Short rate well test data may occur when companies try to cut costs of well test jobs or mostly due to improper well test design. Nevertheless, one may wish to extract the most amount of information from this limited data because the de-convolve response can allow the reservoir engineer to make the best use of the available data in selecting a suitable interpretation model by narrowing down the possible boundary models and also providing a reliable estimates of model parameters. The aim of this study is to demonstrate the usefulness and significance of pressure-rate deconvolution in analyzing relatively short variable rate data using a hypothetical case study. The simulation was carried out using Sapphire’s test design module by assuming the presence of an exploratory well in an oil reservoir above bubble point pressure. Further assumption is that the reservoir is homogenous, therefore the possibility of a changing wellbore model was neglected from the analysis. The computer codes for the simulation were inputted using python programming language. We observed from the study that although pressure and flow rate relationship can be nonlinear, the problem can be formulated as a linear problem and the nonlinearity is expressed in the features of the reservoir. The simulation results were satisfactory using the test case and deviations between model parameters and actual reservoir parameters used in simulation was shown to have an absolute value less than 8% which is within acceptable engineering limits.
