Ride-sharing aims to increase vehicle occupancy rates by matching riders with the drivers, who have empty seats on their vehicles and have similar routes and time schedules. Regarding to the success of a ride-sharing system, many researchers have been interested in efficient ride-matching algorithms. Ride-matching optimization problem is considered as NP-Hard Problem. In most of the ride-matching algorithms in the literature, to be able find matches at short notice some parameters were omitted. Hence, social characteristics and choices of participants, such as gender, age, employment status and willingness to socialize, were not included in many ride-matching algorithms. In this paper, the effects of including such factors in a ride-matching algorithm on the performance and the quality of the matches are investigated. Several ride-matching algorithms in the literature are simulated with randomly generated data. The simulation results show that when social factors are included the computation times and the quality of the matches increase significantly.","PeriodicalId":23377,"journal":{"name":"Turkish Journal of Engineering and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82360828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gender identification is important in animal breeding, focusing on the desired outcome and planning. The data used to determine the gender of calves were the speed, magnitude, and density of the bull's semen. The analysis of the related studies showed that there was not a study on gender prediction of bovine with the application of AI methods. In this study, fuzzy logic (FL), artificial neural networks (ANN), support vector machines (SVM), and random forests (RF) were used. The efficiency of these approaches was verified by statistical analysis parameters such as accuracy, specificity, sensitivity (recall), precision, and F-score. The FL, ANN, SVM, and RF models had 84%, 96%, 97%, 99% accuracy, 93.75%, 96.88%, 100%, 100% sensitivity, 66.66%, 94.44%, 92.31%, 97.30% specificity, 83.33%, 96.88%, 95.31%, 98.44% precision results, respectively. Application of these AI techniques for prediction bovine gender proves that these methods may be used by semen breeders as supporting information tools. In particular, it was observed that the RF method yielded the highest accuracy results.","PeriodicalId":23377,"journal":{"name":"Turkish Journal of Engineering and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88798667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples with four different orientation angles (0o/90o, 15o/-75o, 30o/-60o and 45o/- 45o) fabricated by vacuum assisted resin transfer molding have being tested on the Charpy impact test machine. Furthermore, failure modes of notched/unnotched samples subjected to impact loadings in the flatwise and edgewise directions have been examined to detailly understand fracture behavior. The results showed that the fiber orientation angle has substantial effects on the energy absorption capability and impact toughness of the samples. The increment in fiber orientation angle was led to increases in impact energy and toughness, and the reduction in impact damage. The best values as 3.07 J and 34.82 kJ/m 2 for impact energy and impact toughness, respectively, are obtained from the notched samples in edgewise impact loading that having (45o/-45o) fiber orientation angle. Almost all of the samples exhibited failure modes as matrix fragmentation, delamination, fiber cracking and fiber pull-out, respectively. The most destructive results were observed as laminate fracture on the samples having (0o/90o) fiber orientation angle.","PeriodicalId":23377,"journal":{"name":"Turkish Journal of Engineering and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81949072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wastewater generated from this industry can be considered biowaste. The microbial fuel cells (MFC) are a relatively new technique aiming to treat the wastewater and producing direct energy. This study aims to explore the degradation efficiency of the organic matters expressed as chemical oxygen demand (COD) founded in bulgur industry wastewater by microbial fuel cell techniques. Furthermore, it aims to study the potential formation of electricity from this type of wastewater. In this study, the MFC – double chamber system was performed. 1.5 L bulgur industry wastewater containing 3% of biomass was used. The COD and the voltage were measured. The COD generated from the bulgur industry wastewater was 28800 mg/L. After using the MFC system, the COD was decreased to reach 2560 mg/L with a removal efficiency of 91%. 1st order kinetic model had the best fit for COD removal with a correlation coefficient (R2) of 0.95. The maximum and average voltages were 0.448 Volt and 0.180 Volt, respectively. The average voltage for every 1 m2 was 45 volt. As a result of the exploratory study, the MFC can be used to treat the bulgur industry wastewater and generating energy. But it should be combined with other treatment methods to meet the standards.","PeriodicalId":23377,"journal":{"name":"Turkish Journal of Engineering and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83479801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synthesized Co 3 O 4 /Fe 3 O 4 NPs were characterized by SEM and XRD analysis. The synthesized nanoparticles were used as an adsorbent for the removal of a kind of antibiotic as Tetracycline (TC) from aqueous solutions. According to characterization results, small plate-like structures and agglomerated irregular spherical nanosized particles (101.85 ± 15.04 nm) were formed. The XRD data confirmed the structure of synthesized adsorbent was Co 3 O 4 /Fe 3 O 4 . The optimum tetracycline adsorption conditions were determined as the initial pH of solution 9.0, temperature 55°C, and adsorbent concentration 3.0 g/L. A linear increase was observed in equilibrium uptakes of TC with the increasing the initial antibiotic concentrations. The experimental equilibrium data was modelled with Langmuir and Freundlich isotherm models. The experimental equilibrium data was the best agreement to the Langmuir isotherm model. The maximum monolayer coverage capacity of Co 3 O 4 /Fe 3 O 4 NPs for TC adsorption was found to be 149.26 mg/g at 55°C optimum temperature. The experimental kinetic adsorption data were defined as the best agreement with the pseudo-second-order kinetic model. Weber Morris mass transfer modelling results showed that both the film (boundary layer) and intra-particle diffusion were effective in the adsorption process. The thermodynamic studies suggested that the adsorption process was endothermic, spontaneous and the positive ΔS value indicated increased disorder at the solid-solution interface during the adsorption. Moreover, the synthesized adsorbent showed high adsorption efficiencies at the end of seven sequence usages.","PeriodicalId":23377,"journal":{"name":"Turkish Journal of Engineering and Environmental Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87382983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
