3. 12. The Vowel Systems of Five Iranian Balochi Dialects

   Författare :Farideh Okati; Åke Viberg; Carina Jahani; Pétur Helgason; Jan-Olof Svantesson; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Balochi; Persian; Iranian Balochi dialects; vowel system; Common Balochi; fronting; diphthongization; nasalization; Linguistics; Lingvistik;

   Sammanfattning : The vowel systems of five selected Iranian Balochi dialects are investigated in this study, which is the first work to apply empirical acoustic analysis to a large body of recorded data on the vowel inventories of different Balochi dialects spoken in Iran. The selected dialects are spoken in the five regions of Sistan (SI), Saravan (SA), Khash (KH), Iranshahr (IR), and Chabahar (CH) located in the province Sistan and Baluchestan in southeast Iran.

4. 13. Mechanical optimization of orthopaedic bone screw constructs

   Författare :Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

   Sammanfattning : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. LÄS MER

5. 14. Frequency combs on chip for interferometry applications

   Författare :Israel Rebolledo Salgado; Martin Zelan; Victor Torres-Company; Karsten Rottwitt; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical frequency combs; microcombs; pulses; nonlinear optics; interferometry; integrated photonics; spectroscopy;

   Sammanfattning : Optical frequency combs have revolutionized the field of laser spectroscopy. A frequency comb is a type of laser that generates an array of equally spaced coherent laser lines. Indeed, the outstanding performance of frequency combs in terms of bandwidth and stability is readily attainable in bench-top systems. LÄS MER
