The Electric Home Health Care Routing and Scheduling Problem With Time Windows and Fast Chargers
No full textKoc, Cagri/0000-0002-7377-204X; Yucel, Eda/0000-0002-3448-1522This paper introduces the electric home health care routing and scheduling problem with time windows and fast chargers. The problem aims to construct the daily routes of health care nurses so as to provide a series of services to the patients located at a scattered area. The problem minimizes the total cost, which comprises of total traveling cost of electric vehicles, total cost of uncovered jobs, and total costs of recharged energy. We develop an adaptive large neighborhood search heuristic, which contains a number of advanced efficient procedures tailored to handle specific features of the problem. The paper conducts extensive computational experiments on generated benchmark instances and assesses the competitiveness of the heuristic. Results show that the heuristic is highly effective on the problem. Our analyses quantify the advantages of considering all charger technologies, i.e., normal, fast-and super-fast. We show that the downgrading of competence levels of jobs yields an improvement in total cost.Acknowledgments This work was supported by the Scientific and Technological Re-search Council of Turkey (T?B?TAK) under grant number 119M007.

Co-Creating Positive Outcomes in Higher Education: Are Students Ready for Co-Creation?
No full textStudent engagement has been extensively studied from 'student as co-producer' and 'student as customer' perspectives, while co-creation may provide a renewed framework aiming for an extended and more useful relationship between students and instructors through dyadic interactions. With the intention of theorizing co-creation in a more comprehensive model, the present study incorporates 'operant resources' as antecedents to the formation of a co-creative relationship. The model also proposes that co-creation is a mediator between resources and outcomes. Lastly, the strength of the bond between students and instructors moderates this relationship. Based on fifteen in-depth interviews, the higher education context is reflected more accurately. The qualitative findings are used to construct a questionnaire, which is then administered among 172 students at two different times to capture the evolving student-educator bond. Results support our proposed model and a discussion is made on co-creation as a methodical process in an ecosystem entangling various stakeholders
Moving Object Detection and Counting in Traffic With Gaussian Mixture Models and Vehicle License Plate Recognition With Prewitt Method
No full text6th International Symposium on Multidisciplinary Studies and Innovative Technologies, ISMSIT 2022 -- 20 October 2022 through 22 October 2022 -- 184355Detection and counting of moving objects and recognition of license plates are important processes in traffic surveillance. In this study, the development of moving object detection and counting and license plate recognition algorithms are explained. Gaussian mixture models are used to detect, track and count the moving objects in a video sequence. The algorithm shows the total number of moving objects on the left corner of the processed video frame. Prewitt operator and optical character recognition are used to recognize vehicle's license plate. License plate recognition algorithm can recognize license plates of different types of vehicles in different positions without any character limit. Moving object detection and counting algorithm is tested using different videos of moving objects. Then, license plate recognition algorithm is tested using various photos of the different types of vehicles. It could be evaluated that moving object detection and counting algorithm easily detects and counts the moving objects and vehicle license plate recognition algorithm clearly recognizes license plates of the cars. © 2022 IEEE
Comparison of Time-Domain Antenna Performances for the Terahertz Photoconductive Sources and Detectors
No full textConference on Terahertz Photonics II Part of SPIE Photonics Europe Conference -- APR 03-MAY 20, 2022 -- ELECTR NETWORKThe aim of this study is to investigate and design broadband, terahertz antennas for the time-domain, pulsed operation of the photoconductive sources and detectors. Different antenna types, i.e., thick dipole, bowtie, and spiral antenna, are designed, and their performances are analyzed both analytically and numerically for radiation in 0.8-2 THz band. A very effective ultra-wideband antenna configuration, Archimedean spiral antenna, which has promising time-domain radiation results according to analytical studies, is proposed for terahertz radiation. To the best of the authors' knowledge, this is the first study on fully time-domain analysis of terahertz antennas operating in 0.8-2 THz band.This project is supported by TUBITAK under grant 119E501.SPIE,IdEx Univ Strasbourg,CNRS,ICube,Univ StrasbourgTUBITAK [119E501
Aşağıdan Yukarıya Güvenlik Baskısı: Türkiye'de Suriyelilerin Twitter Üzerinden Güvenlik Çerçevelemesi Analizi
No full textOver time, Turkey has become a country of immigration from an emigration country. The most recent example of this is the Syrian migration to Turkey after the civil war in Syria in 2011. Although government officials in Turkey have emphasized the humanitarian dimension towards Syrians since the beginning of the crisis, the perception of the host community has varied greatly. Although the policy of acting with the perception of a security threat in the border region with Syria was adopted, it was seen that the Syrians were not taken into the security area by the state. In this thesis, it was found appropriate to use the Securitization Theory for the analysis of the construction of Syrians as a security threat from a societal level. Twitter, a social media platform that people can use to express their thoughts, was chosen in order to analyze that security construction in Turkey is supported not only by elite discourses but also by the public. For the analysis made on Twitter, datas containing the words "Syrian" or "Syrians" were collected between January 2011 and December 2022. With the conceptualizations and common dimensions obtained as a result of the literature review, quantitative and qualitative findings on the security threat perceptions of the analyzed Tweets built on the social dimension, crime dimension, economic dimension and political dimensions has been shared.Türkiye zaman içerisinde göç veren ülke konumundan göç alan ülke konumuna gelmiştir. Bunun en güncel örneği ise 2011 yılında Suriye'deki iç savaş sonrasında Türkiye'ye doğru yaşanan Suriyeli göçüdür. Her ne kadar Türkiye'deki hükümet yetkilileri krizin başından itibaren Suriyelilere karşı insani boyutu ön plana çıkarsa da ev sahibi topluluğun algısı, büyük oranda farklılaşmıştır. Suriye ile olan sınır bölgesinde güvenlik tehdidi algısı ile hareket etme politikası benimsenmesine karşın Suriyelilerin devlet tarafından güvenlik alanına alınmadığının tercih edildiği görülmüştür. Bu tez çalışmasında, toplumsal düzeyde bakıldığında, Suriyelilerin bir güvenlik tehdidi olarak inşa edilmesinin analizi için Güvenlikleştirme Teorisi'nin kullanılması uygun bulunmuştur. Güvenlik inşasının Türkiye'de yalnızca elit söylemleri ile değil halk tarafından desteklendiğini analiz etmek adına, insanların düşüncelerini ifade etmek için kullanabilecekleri bir sosyal medya platformu olan Twitter seçilmiştir. Twitter üzerinden yapılan analiz için Ocak 2011 ile Aralık 2022 yılları arasında "Suriyeli" veya "Suriyeliler" kelimeleri geçen veriler toplanmıştır. Yapılan literatür taraması sonucunda elde edilen ortak boyutlar ve kavramsallaştırmalar ile analiz edilen Tweetlerde toplumsal boyut, suç boyutu, ekonomik boyut ve siyasal boyutlar üzerinde inşa edilen güvenlik tehdidi algılarına yönelik nicel ve nitel bulgular paylaşılmıştır
Comparison of the Kisspeptin Levels in Early Onset Preeclampsia and Late-Onset Preeclampsia
No full textObjective Maternal Kisspeptin plays role in cell migration which is responsible for trophoblast invasion. We aimed to investigate the role of Kisspeptin as an invasion marker in the early-onset and late-onset preeclampsia cases. Study design In this case-control study, 125 patients were included: 20 patients with early-onset preeclampsia and 20 gestational-age-matched healthy controls; 45 patients with late-onset preeclampsia and 40 gestational-age-matched controls). Maternal plasma Kisspeptin concentration was measured and compared in groups regarding the presence of early-onset and late-onset preeclampsia. Results In the late-onset PE group, significantly higher maternal plasma Kisspeptin values were observed compared with the control group at > 34 weeks of gestation (68.7 +/- 93.4 pg/ml vs 68.5 +/- 57.9 pg/ml; p = 0.004). Before the 34th week of gestation, plasma Kisspeptin levels did not show a significant difference when patients with early-onset PE and gestational-age matched controls were compared (66.8 +/- 87.9 pg/ml vs 48.5 +/- 91.3 pg/ml; p = 0.56). Conclusion Plasma Kisspeptin levels were significantly higher in women with late-onset preeclampsia, while no significant difference was observed in early-onset preeclampsia when compared with healthy gestational age-matched controls. The role of Kisspeptin proteins is still not clearly defined in the pathogenesis of preeclampsia
Search for Higgs Bosons Decaying Into New Spin-0 or Spin-1 Particles in Four-Lepton Final States With the Atlas Detector With 139 Fb(-1) of Pp Collision Data at Root S=13 Tev
No full textSearches are conducted for new spin-0 or spin-1 bosons using events where a Higgs boson with mass 125 GeV decays into four leptons (l = e, mu). This decay is presumed to occur via an intermediate state which contains two on-shell, promptly decaying bosons: H -> XX/ZX 4l, where the new boson X has a mass between 1 and 60 GeV. The search uses pp collision data collected with the ATLAS detector at the LHC with an integrated luminosity of 139 fb(-1) at a centre-of-mass energy root s = 13 TeV. The data are found to be consistent with Standard Model expectations. Limits are set on fiducial cross sections and on the branching ratio of the Higgs boson to decay into XX/ZX, improving those from previous publications by a factor between two and four. Limits are also set on mixing parameters relevant in extensions of the Standard Model containing a dark sector where X is interpreted to be a dark boson.We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

Modeling and Verification of Firing Dynamics of a Multiple Launch Rocket System
No full textASME International Mechanical Engineering Congress and Exposition (IMECE) -- OCT 30-NOV 03 -- 2022 -- Columbus -- OHMultiple rocket launcher systems have great strategic importance in today's defense systems. Therefore, the development and the quality of these strategically important systems are among the priorities of defense industry companies. The quality of the multiple launcher rocket systems is twofold. 1) Firing the ammunition with the appropriate time interval within the correct trajectories, 2) leaving the firing location quickly after completing the mission. In this study, stabilizer support legs were not used to increase vehicle mobility. The dynamics of a multiple rocket launch vehicle are modeled using rigid bodies and elastic elements with eight degrees of freedom in total. Since a 90-degree firing was performed relative to the longitudinal direction, half-vehicle modeling has been developed in the lateral direction of the vehicle. Firing tests had been executed without a support leg over a Multiple Launch Rocket System. During the firing, measurements were taken with a 3-axis accelerometer and gyroscope over the elevation and azimuth platforms. In addition, LPTs in vertical and lateral directions are placed on the superstructure. With these LPTs, the data obtained from the 3-axis accelerometer and gyroscope on the azimuth platform have been confirmed. The model parameters, stiffness/damping parameters of tires, suspensions, and hydraulic actuator, have been obtained using initial test results with MATLAB (TM) Parameter Estimator toolbox. The model's accuracy has been verified with a second firing test result.Amer Soc Mech Engineer
The Effects of a Game-Enhanced Learning Intervention on Foreign Language Learning
No full textThe rich multimedia-enhanced language content offered by modern commercial off-the-shelf games and students' interest in playing such games has motivated efforts for seeking effective means to integrate them into the curriculum to enrich and enhance foreign language learning. Despite the general interest and appeal of game-enhanced learning in foreign language learning, there is a need for strategies for effective curriculum integration and empirical studies to test the effects of such interventions systematically. This study aims to contribute to this need by investigating the effectiveness of a ten-week-long game-enhanced language learning intervention on English foreign language learning. The study employed an embedded mixed methods design, including a controlled experiment and semi-structured interviews. The experiment group (n = 38) participated in a game-enhanced language learning program that was designed based on the Play Curricular activity Reflection Discussion (PCaRD) framework, whereas the control group (n = 38) received conventional instruction. Students took the TOEFL-ITP and L2 motivational self-system questionnaire before and after the intervention, whereas qualitative data were gathered via semi-structured interviews. The results indicated that both groups had significantly improved their scores, yet no significant differences were found in their post-test scores. The motivation questionnaire revealed a significant difference in cultural interest and attitudes to target community dimensions in favor of the game-enhanced condition. Moreover, the interview results indicated that participants had positive attitudes towards integrating commercial games into their language classrooms. Although the experimental group did not significantly outperform the control group, the game-enhanced intervention provided an equally effective learning experience with improved motivational attributes.School of Foreign Languages at TOBB University of Economy TechnologyThe authors would like to thank to School of Foreign Languages at TOBB University of Economy ; Technology for their support and approval to conduct this study with their students
