    Thesis (Master's)--University of Washington, 2025This thesis presents the design, implementation, and characterization of a Rubidium-87Magneto-Optical Trap (MOT) developed as a part of the foundation of a neutral atom quantum computing platform. A two-dimensional (2D) MOT and a 2D+ MOT configuration are realized to generate and deliver a cold atomic beam for future three-dimensional trapping. The experimental system integrates laser locking based on saturated absorption spectroscopy, radio-frequency control of acousto-optic and electro-optic modulators, permanentmagnet field generation, and a real-time FPGA-based control system. The 2D MOT is characterized using fluorescence imaging, and the 2D+ atomic beam is characterized by transversal probe beam spectroscopy. We extract the linewidth and assess Doppler and power-broadening effects. The results demonstrate stable generation of a collimated atomic beam and establish a robust testbed for future integration with optical tweezers and scalable neutral atom quantum computing architectures

    Masa remaja merupakan masa dimana krisis identitas melanda dan pengakuan akan diri dibutuhkan. Masa ini juga masa dimana iman bergejolak sehingga butuh dukungan dari keluarga dan komunitas iman untuk mempertahankannya. Keluarga merupakan pusat utama kehidupan rohani seseorang. Keluarga yang harmonis akan membangun kehidupan rohani dengan baik. Namun, tidak semua keluarga berada dalam kondisi yang baik bahkan tidak sedikit keluarga yang sudah tidak utuh karena adanya perceraian dan sebagainya. Kondisi keluarga yang tidak baik (broken home), dapat mempengaruhi remaja dalam perkembangan imannya. Oleh karena itu, kelompok persekutuan dibutuhkan untuk dapat membantu remaja dalam meningkatkan pertumbuhan imannya menuju masa dewasa. Melalui penelitian ini, penulis membahas mengenai peran pelayan teruna GPIB Tamansari Salatiga dalam perkembangan iman remaja yang berasal dari keluarga broken home. Penelitian ini bertujuan untuk mendeskripsikan peran pelayan teruna GPIB Tamansari Salatiga dalam membantu perkembangan iman teruna secara keseluruhan dan juga teruna yang berasal dari keluarga broken home ditinjau dari teori perkembangan iman James Fowler. Data yang digunakan pada penelitian diperoleh melalui wawancara kepada para pelayan teruna dan juga teruna GPIB Tamansari Salatiga. Hasil penelitian menunjukkan bahwa pelayan teruna GPIB Tamansari Salatiga cukup baik dalam menghidupi citra diri pelayan teruna, karena dapat melakukan tugas dan tanggung jawab sesuai dengan citra diri pelayan yang dapat menganalisis masalah dan mengerti kebutuhan teruna.Adolescence is a time when an identity crisis hits and self-acknowledgement is needed. This is also a time when faith is in chaos, so it needs support from family and the faith community to maintain it. Family is the main center of one's spiritual life. A harmonious family will build a good spiritual life. However, not all families are in good term nor harmonius, even few families are incomplete due to divorce and so on. Family conditions that are not in a good term (broken home) can affect adolescents in the development of their faith. Therefore, fellowship groups are needed to be able to help adolescents increase their faith growth towards adulthood. Through this research, the author discusses the role of GPIB Tamansari Salatiga’s teruna servant in the development of the faith of adolescents who come from broken home families. This study aims to describe the role of GPIB Tamansari Salatiga teruna servant in helping the faith development of teruna as a whole and also teruna who come from broken homes in terms of James Fowler's theory of faith development. The data used in the study were collected through interviews with GPIB Tamansari Salatiga teruna servants and also teruna. The results showed that GPIB Tamansari Salatiga teruna servant were quite good at supporting the teruna servant’s self-image, because they could carry out their duties and responsibilities in accordance with the servant's self-image who could analyze problems and understand the needs of the teruna

    Berkhotbah merupakan unsur penting di dalam pelayan pertua dan diaken di dalam Gereja Batak Karo Protestan dan menjadi penilaian penting terhadap jemaat. Oleh karena hal tersebut pengajaran mengenai ilmu homiletika sangatlah penting bagi para pelayan gereja untuk mendukung dalam penyusunan naskah khotbah dan cara berkhotbah yang baik. Penelitian ini mengkaji bagaimana peran ilmu homiletika terhadap pengembangan khotbah transformatif bagi pertua maupun diaken di GBKP Runggun Surbakti II Ndokum Siroga. Metode penulisan yang digunakan penulis yaitu metode kualitatif dalam mencari pemecahan masalah dengan memanfaatkan data empiris yang didapat melalui pencarian data dengan baik sehingga dapat memahami situasi permasalahan dan mencari data melalui mekanisme wawancara dengan para pertua dan diaken. Berdasarkan hasil penelitian dan kajian yang dilakukan, maka dapat disimpulkan pada konteks pelayanan di Gereja Batak Karo Protestan Runggun Surbakti II Ndokum Siroga masih bersifat kaku dan mengadopsi pemahaman-pemahaman dari generasi yang tua. Sehingga untuk mendobrak perubahan yang baru di dalam gereja dalam tatanan pelayanan merupakan hal yang sulit, terkhususnya dalam membangun para pertua dan diaken menjadi pengkhotbah yang transformatif. Ilmu homiletika yang dikemukakan oleh Rothlisberger dan Greg Scharf mendorong para pertua maupun diaken untuk membangun kesadaran pentingnya ilmu homiletika dan untuk terus belajar guna membangun cara berkhotbah yang transformatif sesuai dengan kebutuhan jemaat.Preaching is an important element in serving elders and deacons in the Batak Karo Protestant Church and is an important assessment of the congregation. Because of this, teaching homiletics is very important for church ministers to support in preparing sermon texts and how to preach well. This research examines the role of homiletics in the development of transformative sermons for elders and deacons at GBKP Runggun Surbakti II Ndokum Siroga. The writing method used by the author is a qualitative method in finding solutions to problems by utilizing empirical data obtained through data searches well so that they can understand the problem situation and find data through an interview mechanism with elders and deacons. Based on the results of the research and studies conducted, it can be concluded that the service context at the Runggun Surbakti II Ndokum Siroga Batak Karo Protestant Church is still rigid and adopts the understandings of the older generation. So breaking new changes in the church in the order of ministry is difficult, especially in developing elders and deacons into transformative preachers. The science of homiletics proposed by Rothlisberger and Greg Scharf encourages elders and deacons to build awareness of the importance of homiletics and to continue learning in order to develop a transformative way of preaching according to the needs of the congregation

    Kajian Pendidikan Agama Kristen Keluarga Terhadap Pola Asuh Rohani Di Suku Boti

    Pendidikan agama Kristen keluarga merupakan pendidikan yang menempatkan orang tua sebagai pendidik utama bagi anak-anak agar mereka dapat memahami agama Kristen dalam kehidupan mereka. Orang tua memiliki tugas untuk menjadi teladan dalam mengasuh anak-anaknya agar mereka hidup dalam nilai-nilai agama Kristen. Perkembangan agama Kristen yang sangat pesat membuat banyak anggota masyarakat, termasuk masyarakat suku Boti ikut memeluk agama Kristen. Suku Boti merupakan suku yang masih memegang teguh nilai-nilai lokal serta mempraktikan ritus-ritus adat. Penelitian ini bertujuan untuk menganalisis seperti apa pola asuh rohani dalam keluarga Kristen di suku Boti menurut kajian Pendidikan Agama Kristen. Penulis menggunakan metode penelitian kualitatif dengan pendekatan deskriptif untuk memperoleh informasi dan data dari narasumber. Hasil penelitian menunjukan bahwa pola asuh rohani orang tua Kristen di suku Boti lebih banyak dipengaruhi oleh nilai-nilai yang terkandung dalam budaya lokal termasuk nilai-nilai yang tidak sesuai dengan ajaran agama Kristen. Hal ini terjadi karena orang tua Kristen di suku Boti hidup dalam penghayatan budaya dan kebiasaan turun temurun termasuk kebiasaan yang tidak sesuai dengan nilai-nilai yang ada di dalam agama Kristen, contohnya praktek pengobatan, penghormatan terhadap alam dan ritual potong ayam. Namun, orang tua Kristen di suku Boti juga menyadari bahwa sebagai orang yang sudah Kristen, kebiasaan-kebiasaan tersebut perlu dipertimbangkan ulang, akan tetapi belum ada upaya selanjutnya dari para orang tua. Untuk itu, gereja sebagai pelaksana pendidikan agama Kristen perlu memperhatikan setiap anggota jemaat dan mendampingi serta menguatkan para orang tua dan anak-anak dalam upaya tersebut agar jemaat mengalami transformasi sebagai orang Kristen yang berada di suku Boti.Family Christian religious education places parents as the main educators for children so they can understand Christianity in their lives. Parents have a duty to be role models in raising their children so that they live according to the values of the Christian religion. The rapid development of Christianity made many members of society, including the Boti tribe, join Christianity. The Boti tribe is a tribe that still adheres to local values and practices traditional rites. This research aims to analyze what spiritual parenting patterns are like in Christian families in the Boti tribe, according to Christian Religious Education studies. The author uses a qualitative research method with a descriptive approach to obtain information and data from sources. The research results show that the spiritual upbringing of Christian parents in the Boti tribe is more influenced by the values contained in local culture, including values that are not in accordance with the teachings of the Christian religion. This happens because Christian parents in the Boti tribe live by observing the culture and habits passed down from generation to generation, including habits that are not in accordance with the values contained in the Christian religion, for example, medical practices, respect for nature, and chicken slaughter rituals. However, Christian parents in the Boti tribe also realize that, as people who are Christians, these habits need to be reconsidered, but there has been no further effort from the parents. For this reason, as the implementer of Christian religious education, the church needs to pay attention to every congregation member and accompany and strengthen parents and children in this effort so that the congregation experiences transformation as Christians in the Boti tribe

    Kajian Pendidikan Agama Kristen terhadap Peran Orangtua dalam Pertumbuhan Spiritualitas Anak dan Implikasinya bagi Kemajuan Jemaat di GKS Pusat Pelli

    Orang tua memiliki peran yang signifikan dalam kehidupan spiritualitas anak. Melalui perannya sebagai pendidik, orang tua dapat memaksimalkan tanggung jawabnya untuk membimbing, mengajar, dan memfasilitasi anak dalam pendidikan agama Kristen, sehingga dapat berdampak pada pertumbuhan spiritualitasnya. Keteladanan orang tua dalam pelaksanaan pendidikan agama Kristen keluarga menjadikan anak dapat mengimplementasikan nilai-nilai Kekristenan yang diajarkan. Didikan ini berdampak ketika anak telah bertumbuh dewasa dan membantu anak menyadari panggilannya untuk terlibat mengusahakan pertumbuhan dan kemajuan jemaat. Sebab, Gereja yang maju adalah mampu memberdayakan setiap anggota jemaatnya terlibat secara aktif dalam pelayanan gereja serta dapat menyediakan pelayanan yang menjawab semua kebutuhan jemaatnya. Penelitian ini bertujuan untuk mendeskripsikan kajian pendidikan agama Kristen keluarga yang dilakukan orang tua terhadap pertumbuhan spiritualitas anak dan implikasinya bagi kemajuan jemaat di GKS Pusat Pelli. Penulis menggunakan pendekatan deskriptif kualitatif dengan teknik pengambilan data wawancara kepada sepuluh orang informan. Hasil penelitian menunjukkan bahwa orang tua belum memahami pendidikan agama Kristen seutuhnya. Orang tua menganggap bahwa pendidikan agama Kristen hanya menjadi tanggung sekolah minggu dan sekolah sebagai lembaga formal yang berkompeten di bidang tersebut. Namun, ketika mewawancarai para presbiter, penulis menemukan mereka memahami hakikat dari pendidikan agama Kristen, tetapi belum ada upaya melalui program gereja, yang dapat membekali orang tua dalam mendidik anak-anak dalam lingkungan keluarga. Oleh karena itu, melalui tulisan ini diharapkan gereja maupun orang tua dapat membentuk usaha kolaboratif dalam mempersiapkan generasi penerus yang berperan aktif dalam pertumbuhan maupun kemajuan jemaatnya. Kata Kunci : PAK Keluarga, Peran Orang Tua, Spiritualitas Anak, dan Kemajuan Jemaat GKS Pusat Pelli ABSTRACT Parents have a significant role in the spiritual life of children. Through their role as educators, parents can maximize their responsibility to guide, teach, and facilitate children in Christian religious education, so that it can have an impact on their spiritual growth. The example of parents in carrying out family Christian education makes children able to implement the Christian values that are taught. This education has an impact when the child has grown up and helps the child realize the calling to be involved in the growth and progress of the church. This is because an advanced church is able to empower every member of its congregation to be actively involved in church ministry and to be able to provide services that answer all the needs of its congregation. This study aims to describe the study of family Christian education conducted by parents on the growth of children's spirituality and the implications for the development of the congregation at GKS Pusat Pelli. The author uses a qualitative descriptive approach with data collection techniques interviewing ten respondents. The results of the study show that parents do not fully understand Christian education. Parents consider that Christian education is only the responsibility of the church (Sunday school) and the school as a formal institution that is competent in this field. However, when interviewing the presbyters, the writer found that they understand the essence of Christian education but there has been no effort through the church's program, which can equip parents in educating their children in a family environment. Therefore, through this writing it is hoped that both the church and parents can form a collaborative effort in preparing the next generation to play an active role in the growth and progress of their congregation. Keywords: Family Christian Education, Parent’s Rple, Children Spirituality, and Development of GKS Pusat Pelli

    Techno-economic assessment of new marine engine development with high noise and vibration performance

    Općenito je poznato da problemi buke i vibracija karakteriziraju gotovo sve brodove. To je posebice naglašeno kod malih brodova, putničkih brodova i velikih kruzera. Ovaj diplomski rad vezan je za problem buke i vibracija na kruzerima, koji su prvenstveno uzrokovani radom četverotaktnih dizelskih motora. Naime, većina od prezentiranih rezultata u okviru ovog rada plod je istraživanja autorice za vrijeme tromjesečnog boravka u razvojnom odjelu proizvođača brodskih motora Wärtsilä u Trstu. Štoviše, istraživanja koja su provedena u okviru ovog rada predstavljaju početni dio dugogodišnjeg istraživačkog projekta koji provodi Wärtsilä s ciljem razvoja motora niske razine buke i vibracija. U tom smislu kao glavno pitanje postavlja se dvojba trebaju li se propisane razine buke i vibracija nastojati ostvariti konverzijama postojećih motora ili razvojem potpuno novih motora. Također, potrebno je dati odgovor na pitanje jesu li samo zahvati na motoru dovoljni ili su nužni i zahvati na samoj konstrukciji broad. Stoga, u radu je dan pregled problema buke i vibracija na brodovima. Opisani su osnovni principi njihove propagacije kroz konstrukciju. Analizirani su zahtjevi klasifikacijskih društava prema tzv. klasama komfora, kao i izmereni rezultati u naravi na postojećim brodovima. Uspostavljen je odnos između poboljšanja kvalitete motora i klase komfora. Utjecaj vibracija na cijene putničkih kabina analiziran je na temelju stvarnih podataka za brodove za kružna putovanja. Naposljetku, generiran je pojednostavljeni model buke na brodovima, koji je razmatran hibridnom statističkom analizom energije kako bi se identificirali dominantni utjecajni parametri buke koje valja varirati kako bi se smanjile njene razine na brodu. Zajedno sa zaključnim razmatranjima diplomskog rada, dane su smjernice za buduća istraživanja.It is well known that noise and vibration are problems that are inherent to almost all ships. This is particularly emphasized in case on small ships, passenger vessels and large cruise ships. This thesis deals with noise and vibration problems onboard cruise ships that are primarily induced by four stroke diesel engines. Namely, the most of the presented research results was performed during the 3-month visit of the author to the engine producer Wärtsilä. Moreover, the investigation performed within this thesis is an initial part of long-term research project which is being performed by Wärtsilä with an aim to develop an engine with low emissions of noise and vibration. In this sense, the main issue is whether the prescribed noise and vibration levels should be achieved by conversions of existing engines, or completely new engine should be developed. Also, it is to be found whether only treatments on the engines are enough, or there are some modifications on ship structures that should be undertaken. In this work an overview of noise and vibration problems in ships is given. Basic principles of their propagation within the structure are described, together with brief description of measurement techniques. Requirements of Classification Societies on Comfort Class are analyzed in details as well as the measured full-scale results from the existing engines/ships. The relation between improvements in engine quality and comfort class is established. The influence of vibration levels on cabin prices is analyzed taking into account realistic data of cruise ship fleet. Finally, a simplified noise model is generated and analyzed by the hybrid Statistical Energy Analysis in order to specify most dominant influence parameters onboard, that should be changed to achieve lower noise levels. Together with thesis concluding remarks, recommendations for further research are given

    Synthesis and Characterization of Homogeneously Dispersed Graphene–copper Heterostructures With Enhanced Thermal Properties

    Graphene-reinforced copper composites have gained significant attention due to their exceptional properties and potential applications across various industries. This study presents a novel approach to synthesize 3D graphene–copper heterostructures using a plasma-enhanced chemical vapor deposition (PECVD) technique. The method involves encapsulating Cu powders with graphitic layers through PECVD at a low temperature of 400 °C to prevent copper powder agglomeration during the process, ensuring uniform graphene coating across the entire copper surface. Microstructural characterization of the resulting 3D graphene–copper heterostructures confirms successful encapsulation, with graphitic coating thicknesses ranging from 5–15 nm. The unique graphene-encapsulated Cu powder structure facilitates pressureless sintering, yielding consolidated composites with exceptional structural integrity. Metallographic analysis of the consolidated samples revealed a uniformly distributed multilayer graphitic network within the graphene–copper (G/Cu) composite structure. The presence of graphene between copper grains is found to inhibit copper grain growth, leading to smaller copper grains compared to graphene-free copper monoliths. Furthermore, the G/Cu composite had significantly reduced pore size and ensuant higher density when compared to the sample prepared without graphene encapsulation. Graphene’s lubricating effect is presumed to enhance the freedom of rotation for copper grains during sintering and cause increased densification. The thermal diffusivity of the graphene–copper heterostructure is measured as 1.38 cm2/s using thermal flash technique, representing an approximate 40% improvement compared to graphene-free copper. This enhancement in thermal conductivity is attributed to the presence of strongly bonded graphene layers between copper grains and additional thermal transport originating from graphitic interface. Thermal diffusivity was decreased monotonically with increasing temperature at temperature range 20–200 °C indicating prevalent phonon contribution. In the context of technological implications, successful synthesis of 3D graphene–copper heterostructures using scalable plasma-enhanced chemical vapor deposition (PECVD) technique establishes a foundation for the development of advanced materials with tailored properties and multifunctional applications, particularly those requiring lightweight characteristics, high transport properties (thermal or electrical), and exceptional mechanical strength. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTAK: 118F49

    Borrowed feathers:the spurious Older Scots ending to Chaucer’s <i>Parliament of Fowls</i> in Bodleian Library MS Arch. Selden. B. 24

    No full text
    Oxford, Bodleian Library MS Arch. Selden. B. 24 has attracted attention in recent years for the witness it bears to the reception of Chaucer in late medieval Scotland. Its most striking example is the spurious seventy-nine-line ending attached to the Parliament of Fowls, edited afresh for this article. This article teases apart the work of the spurious ending’s author from that of the Selden copyist and investigates how, when, and why this peculiar Scottish rewriting of the end of Chaucer’s Parliament came about. That the spurious ending is indeed a Scottish composition is demonstrated through its linguistic features and sly allusions to two fifteenth-century Scots poems, Henryson’s “The Cock and the Fox” and Richard Holland’s Buke of the Howlat. These, in combination with textual and codicological details explored here, suggest strongly that this ending was written in conscious defiance, rather than ignorance, of Chaucer’s conclusion to the Parliament.</p
