Characterizing the mechanical properties of skin-core structure in polymer molding process by nanoindentation

Quality of the polymer product produced by injection molding process are strongly affected by the mechanical properties of the skin-core structure formed during injection molding operation. It is desirable to know the mechanisms of the skin-core structure and the influence from process parameters and material properties to the skin-core formation in the injection molding. This paper focuses on cha

Optimal Electromagnetic Measurements

We consider the problem of obtaining information about an inaccessible halfspace from electromagnetic measurements made in the accessible half-space. If the measurements are of limited precision, some scatterers will be undetectable because their scattered ﬁelds are below the precision of the measuring instrument. How can we make optimal measurements? In other words, what incident ﬁelds should we

Modeling of material behavior in metal forming

Popular Abstract in Swedish Datorbaserade beräknings- och simuleringsmodeller har under de senaste två decennierna kommit att utgöra ett viktigt verktyg i industriella produktutvecklingsprocesser. Med sådana modeller och metoder kan utvecklingstiden kortas och kostnaderna minskas, till exempel genom att färre prototyper behöver framställas och genom att mängden kostsam provning kan reduceras. Bra With an increasing demand to improve efficiency and to cut costs, the industry is constantly seeking to reduce the time and money spent in product development and manufacturing. Use of computer-based simulations has become more or less a standard tool to meet this demand. Cost reduction is in this way made possible by for example shortened product development cycles, less need for expensive protot

This paper presents part of the results of a three-year project funded by the Swedish research Council. The project focusses a hitherto neglected Arabic medical encyclopedia from the 10th century: al-Mu'aladjat al-Buqratiya (Hippocratic treatment) attributed to Abu al-Hasan at-Tabari. The handbook, which comprises 700 pages and is extant only in handwritten form, can be expected to contribute subs
