Extending Electrical Resistivity Measurements in Micro-scratching of Silicon to Determine Thermal Conductivity of the Metallic Phase Si-II
Hisham A. Abdel-Aal, Ysai Reyes, John A. Patten +1
Ductile Regime Machining of semiconductors (DRM) offers higher quality of the resulting surfaces. To optimize this process, it is required to understand the thermal kinetics of sil…
The Relation Between Wear and Irreversible Entropy Generation in the Dry Sliding of Metals
Hisham A. Abdel-aal
We examine the relationship between wear and the generation of entropy in dry sliding of metals. It is postulated that wear is related to irreversible entropy generation within the…
Identifying Shapes Using Self-Assembly (extended abstract)
Matthew J. Patitz, Scott M. Summers
In this paper, we introduce the following problem in the theory of algorithmic self-assembly: given an input shape as the seed of a tile-based self-assembly system, design a finite…
Self-Assembly of Arbitrary Shapes Using RNAse Enzymes: Meeting the Kolmogorov Bound with Small Scale Factor (extended abstract)
Erik D. Demaine, Matthew J. Patitz, Robert T. Schweller +1
We consider a model of algorithmic self-assembly of geometric shapes out of square Wang tiles studied in SODA 2010, in which there are two types of tiles (e.g., constructed out of…
Multi Scale Investigation of Surface Topography of Ball Python (Python Regius) Shed Skin in Comparison to Human skin
H. A. Abdel-Aal, M. El Mansori, S. Mezghani
Constructing a surface that is an integral part of the function of tribosystems (deterministic surface) is an intriguing goal. Inspirations for such surfaces come from studying nat…
Reducing Tile Complexity for the Self-Assembly of Scaled Shapes Through Temperature Programming
Scott M. Summers
This paper concerns the self-assembly of scaled-up versions of arbitrary finite shapes. We work in the multiple temperature model that was introduced by Aggarwal, Cheng, Goldwasser…
