Developing a website with user experience
No full textThe Internet has played an essential role in human life with its convenience, and it has been attached to people’s lives for several decades. Many people daily use the Internet on their own electronic devices for various purposes. In fact, through human habits and behavior that use electronic devices to access the Internet daily, user experience design has been created to enhance the Interaction of humans with the application and websites in their own devices.
The thesis idea was based on Bumi Asian Kitchen & Café, an Asian restaurant in Helsinki. Bumi is also no exception with the traditional business, which has served its regular food menu on the street corner since 2016. By combining technology and human behaviors, the thesis aims to research customer behavior and expectations and develop a website design for a restaurant to bring a convenient user experience and exemplary user interface to its customers. That website design helps the business attract customers, raise the reputation, and enhance customer connection in the smooth method.
In the thesis, the essential design knowledge will clarify the basis of user experience and user interface. The author then keeps researching the website’s basic knowledge to describe the importance of website design and website usability. The author uses the qualitative method and ex-plains the UX design methodology with persona, customer journey, heuristic evaluation, user inter-view, and usability testing before choosing a suitable methodology for the practical process of web-site development for Bumi Asian Kitchen & Cafe. After evaluation based on data collection, author can point out the advantages of website development that bring to a restaurant business

No full textValidation of the corrected Dang Van multiaxial fatigue criterion applied to turret bearings of FPSO offloading buoys
No full textIn engineering practice, multiaxial fatigue analyses are often avoided due to their complexity and computational intensity. However, damages have been encountered in turret bearings of Floating Production Storage and Offloading vessel (FPSO) offloading buoys which were likely caused by multiaxial fatigue. The Dang Van criterion has often been used to assess problems with multiaxial fatigue in rolling contacts. Therefore, this study set out to validate the application of the Dang Van criterion to turret bearings of FPSO offloading buoys. For this purpose, the criterion was corrected with a horizontal conservative locus for compressive hydrostatic stresses. Three load cases were identified based on the seakeeping analysis of an FPSO offloading buoy equipped with a wheel-rail turret bearing. For each load case, the surface pressure distribution and sub-surface stress states were determined analytically. Staircase tests were used to determine the characteristic parameters (α and β) of the Dang Van curve. Then, the Dang Van criterion was corrected and used to perform a multiaxial fatigue analysis in the critically stressed area of the wheel-rail contact. Finally, full-scale, long-duration fatigue tests were used to validate the results. The corrected Dang Van criterion shows agreement with the experimental results and is not rejected as multiaxial fatigue criterion for application to turret bearings in FPSO offloading buoys

Holotype ♀, China, Hunan, Yongzhou, Dupangling National Nature Reserve (25.46°N, 111.37°E; elev. 380 m), from the root of Poaceae grasses (Fig. 15), 4.IX.2020, coll. Xia Wang. Paratype. 1♂, same data as holotype.</p> <p> Etymology. This species name is composed of the Latin word, “ <i>elongatus</i> ”, based on its elongated preoclular projection of head.</p> <p> Comments. This new species can be recognized as the genus <i>Ophthalmothrips</i> by the elongated preocular projection of the head, which is about 1.4 times as long as its wide. Similarly, this character is also present to <i>O. faurei</i> and <i>O. longiceps</i>. But the new species differs by having postocular setae small (not reaching at posterior margin of eyes), interocellar setae, pronotal epimal setae well-developed and pelta triangular with slightly rounded laterally. In <i>O</i>. <i>faurei</i>, the original description showed that it had postocular setae well-developed (Ananthakrishnan, 1964); Ananthakrishnan (1973) redescribed both sexes of <i>O</i>. <i>faurei</i> in detail, of which its postocular setae were also developed, interocellar setae absent, and one pair of median dorsal setae of head well-developed (but we think that these setae were probably located ventrally.); Haga (1975) studied Ananthakrishnan’s specimens of <i>O</i>. <i>faurei</i>, and showed that the pronotal epimeral setae are small and the interocellar setae developed. The genus <i>Ophthalmothrips</i> was reviewed worldwide by Minoura & Mound (2019) as the latest research. They recorded only one female represented as <i>O</i>. <i>faurei</i> from Guilin City in China, but the author helped to re-check this specimen, and found its head was too dark to see any characters. And the specimens from Japan identified as <i>O</i>. <i>faurei</i> together with Chinese specimen showed developed postocular setae. Thus, the only female specimen identified as <i>faurei</i> need to further study in the future. In <i>O. longiceps</i>, it is distinguished from <i>O</i>. <i>elongatus</i> Li & Dang, <b>sp. nov.</b> by the shorter preocular projection (wider than long), the well-developed postocular setae, and the pelta sharply pointed laterally.</p> <p> Figures 16–25. <i>Ophthalmothrips formosanus</i> (16–17, 21–22, 24), <i>O. miscanthicola</i> (18, 20, 23) and <i>O. longiceps</i> (19, 25). 16.
