Design thinkin metodit laivan konseptisuunnittelun alkuvaiheessa

The widely used for ship concept design is the traditional ship spiral. The spiral model has not changed or developed since it was introduced back in 1959. This causes problems in the modern-day work environment, as cruise ship design changes and develops fast and often during the first stages of the concept development. Due to this new model of designing is needed. In addition to a new model, newer methods are also needed. This research aims to study different design thinking models and methods and suggest a new process connecting the double spiral model with design thinking methods. The design thinking methods are analysed through the point of view of the usage in naval architecture work, and for each method, an example of the usage is suggested. In addition to the example, the methods are also divided into three groups based on the usage of them by Meyer Sales and Design team. Finally, the suggested methods are evaluated by using them to find out the wants and need of the passenger in future cruise ships and is this knowledge important for the shipyard. Based on the data collected by using several different design thinking methods, the conclusion is that the passengers can point out what does and does not work and if there is room for improvement. In addition, the data collected from the methods support the claim that the shipyard would benefit from the information.Laivojen konseptisuunnittelussa käytetään yleisesti perinteistä suunnitteluspiraalia. Spiraalimalli ei ole muuttunut tai kehittynyt sen jälkeen, kun se otettiin käyttöön vuonna 1959. Tämä aiheuttaa ongelmia nykyaikaisessa työympäristössä, koska risteilyalusten suunnittelu muuttuu ja kehittyy nopeasti ja usein konseptikehityksen ensimmäisissä vaiheissa tarvitaan uusia menetelmiä. Tämän uuden suunnittelumallin vuoksi tarvitaan. Uuden mallin lisäksi tarvitaan myös uudempia menetelmiä. Tutkimuksen tavoitteena on tutkia erilaisia design thinking malleja ja menetelmiä ja ehdottaa uutta prosessia, joka yhdistää double spiral -mallin design thinking menetelmiin. Design thinking menetelmiä analysoidaan laivasuunnittelutyön käytön näkökulmasta, ja kunkin menetelmän osalta ehdotetaan esimerkkiä tämän käytöstä. Esimerkin lisäksi menetelmät on jaettu kolmeen ryhmään, jotka perustuvat Meyerin Sales and Design tiimin käyttöön. Lopuksi ehdotetut menetelmät arvioidaan käyttämällä niitä selvittäämään matkustajan halut ja tarpeet tulevissa risteilyaluksissa, ja onko tämä tieto telakalle tärkeä. Useiden eri suunnittelun ajattelutapojen avulla kerättyjen tietojen perusteella voidaan päätellä, että matkustajat voivat huomauttaa, mikä ei toimi ja mikä on parannettavaa. Lisäksi menetelmistä kerätyt tiedot tukevat väitettä, jonka mukaan telakka hyötyisi tiedoista

Aspek Hukum Dan Tanggung Jawab Pers

Press freedom in Indonesia is not apart from its accountabilities for particular delicts as set forth in Press Act and Criminal Law currently revised in line with the development of era and Indonesian cultures. Accountabilities of the press for delicts include humiliation, slandering, and pornography where such involved parties shall account for. Meanwhile, legal aspects for such involved parties include editor, writer, publisher, printing agency and distributors, with more advantageous legal position compared to the ones of non-press delicts

Low energy magnetic excitation spectrum of the unconventional ferromagnet CeRh3_{3}B2_{2}

The magnetic excitation spectrum of the unconventional ferromagnet CeRh$_{3}$B$_{2}$ was measured by inelastic neutron scattering on single crystal sample in the magnetically ordered and paramagnetic phases. The spin-wave excitation spectrum evidences high exchange interaction along the c-axis about two orders of magnitude higher than the ones in the basal plane of the hexagonal structure. Both strong out of plane and small in plane anisotropies are found. This latter point confirms that considering the $J$=5/2 multiplet alone is not adequate for describing the ground state of CeRh$_{3}$B$_{2}$. Quasielastic scattering measured above $T_{Curie}$ is also strongly anisotropic between the basal plane and the c-axis and suggests localized magnetism.Comment: 8 Figure

Spin fluctuations probed by NMR in paramagnetic spinel LiV2_2O4_4: a self-consistent renormalization theory

Low frequency spin fluctuation dynamics in paramagnetic spinel LiV$_2$O$_4$, a rare 3$d$-electron heavy fermion system, is investigated. A parametrized self-consistent renormalization (SCR) theory of the dominant AFM spin fluctuations is developed and applied to describe temperature and pressure dependences of the low-$T$ nuclear spin-lattice relaxation rate $1/T_1$ in this material. The experimental data for $1/T_1$ available down to $\sim 1$K are well reproduced by the SCR theory, showing the development of AFM spin fluctuations as the paramagnetic metal approaches a magnetic instability under the applied pressure. The low-$T$ upturn of $1/T_1T$ detected below 0.6 K under the highest applied pressure of 4.74 GPa is explained as the nuclear spin relaxation effect due to the spin freezing of magnetic defects unavoidably present in the measured sample of LiV$_2$O$_4$.Comment: 11 pages, 2 figure
