This paper attempts to improve the physical and mechanical properties of selective laser sintered polyamide PA2200 components through a vibratory surface finishing process by inducing severe plastic deformation at the ...

Turkish Building Seismic Code has been revised after eleven years once more and its application is compulsory since the beginning of 2019. The new code is published together with a new Earthquake Hazard Map and it consists ...

This paper focuses on the linking of heritage preservation policies and tourism development, specifically in relation to the cultural landscapes. For this purpose, historic ensembles Blagaj, Jajce and Travnik, that ...

Lithium ion (Li-Ion) and lithium polymer (Li-Po) batteries need to be used within certain voltage/current limits. Failure to observe these limits may result in damage to the battery. In this work, we propose a low voltage ...

Quaternions have become a popular and powerful tool in various engineering fields, such as robotics, image and signal processing, and computer graphics. However, classical quaternions are mostly used as a representation ...

Purpose – The purpose of this paper is to evaluate the effect of post process combinations, e.g. hot isostatic pressing (HIP) only, HIP 1 T6 heat treatments, and T6 only, with different aging time, on surface properties, ...

Retrieving relevant documents from a large set using the original query is a formidable challenge. A generic approach to improve the retrieval process is realized using pseudo-relevance feedback techniques. This technique ...

Selective Laser Sintering (SLS) is an accepted and improving technique for additive manufacturing in many different areas, from the applications of aerospace to automotive, consumer products to dental and medical materials. ...

Fluorescence imaging of sub-cellular structures with sizes below the di raction limit is vital in understanding cellular processes. Relying on exciting the sample with di erent illumination patterns and image processing ...
