1. 1. Exploring and extending eigensolvers for Toeplitz(-like) matrices : A study of numerical eigenvalue and eigenvector computations combined with matrix-less methods

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Martin Knebel; Fredrik Cers; Oliver Groth; [2022]
   Keywords : Toeplitz matrices; eigenvalue computation; eigenvector computation; matrix-less methods;

   Abstract : We implement an eigenvalue solving algorithm proposed by Ng and Trench, specialized for Toeplitz(-like) matrices, utilizing root finding in conjunction with an iteratively calculated version of the characteristic polynomial. The solver also yields corresponding eigenvectors as a free bi-product. READ MORE

3. 2. Design and construction of a contactless excitation and response measurement system

   University essay from KTH/Industriell produktion

   Author : Johan Westlund; [2019]
   Keywords : Rotor dynamic; Electromagnet; Contactless excitation; LabVIEW; Measurement instruments; Force control; CERS; Rotordynamik; Elektromagnet; Kontaktlös exitation; LabVIEW; Kraftkontroll; CERS;

   Abstract : Manufacturing industry works on Overall Equipment Effectiveness (OEE) to increase the yield and speed of machining. A good knowledge of the machine properties is important to increase the speed while still maintaining stable cutting with low tool usage. READ MORE

4. 3. Skin barrier: Extraction and characterization of Stratum Corneum lipids

   University essay from Lunds universitet/Kemiska institutionen

   Author : Nicolas Velásquez González; [2018]
   Keywords : stratum corneum; skin barrier; lipids; physical chemistry; fysikalisk kemi; Chemistry;

   Abstract : The structure and dynamics of isolated Stratum Corneum lipids in different temperatures and hydration conditions was investigated using natural abundance 13 C NMR and X-ray scattering. In order to isolate the lipids a new extraction method was tested. The novel aspect of this method was its ability to extract more lipids from SC. READ MORE

5. 4. Study of vibration severity assessment for Machine Tool spindles within Condition Monitoring

   University essay from KTH/Industriell produktion

   Author : Eduardo Torres Pérez; [2016]
   Keywords : ;

   Abstract : Today, machine tools are indispensable for production of manufactured goods. Several industries rely in this equipment to manufacture finished products by removing material through different cutting operations. Automobile, military and aerospace are just examples of industries where machine tools are used intensively. READ MORE

6. 5. Evaluation of a Contactless Excitation and Response System (CERS) for process planning applications : An experimental study

   University essay from KTH/Industriell produktion

   Author : Laura Montalban; [2016]
   Keywords : mechanical vibrations; natural frequencies; damping ratio; chatter; structural dynamic tests; stability lobe diagrams.; mekaniska vibrationer; egenfrekvens; dämpning; chatter; strukturdynamiska tester; stabilitetsdiagram.;

   Abstract : Chatter vibration is a common problem for the manufacturing industry that limits the productivity, accuracy and surface quality of machined parts. This study is focused on the out of process methods, such as Stability Lobe Diagrams (SLD), that ensure the selection of the optimal cutting parameters in which the machining process is stable.
