Effects of Cooking End-point Temperature and Muscle Part on Sensory ‘Hardness’ and ‘Chewiness’ Assessed Using Scales Presented in ISO11036:1994
Beef Texture Sensory Evaluation ISO11036:1994 Cooking End-point Temperature
2016/5/12
Texture and ‘tenderness’ in particular, is an important sensory characteristic for consumers’ satisfaction of beef. Objective and detailed sensory measurements of beef texture have been needed for the...
Why the traditional concept of local hardness does not work
traditional concept local hardness definition chemical potential
2011/8/5
Abstract: The definition of local hardness by the derivative of the chemical potential with respect to the electron density has raised several questions, and its potential applicability as the local c...
NP-hardness of Deciding Convexity of Quartic Polynomials and Related Problems
NP-hardness of Deciding Convexity of Quartic Polynomials Related Problems
2011/1/19
We show that unless P=NP, there exists no polynomial time (or even pseudo-polynomial time)
algorithm that can decide whether a multivariate polynomial of degree four (or higher even
degree) is globa...
Hardness, approximability, and exact algorithms for vector domination and total vector domination in graphs
Hardness approximability exact algorithms vector domination total vector domination
2011/3/2
We consider two graph optimization problems called vector domination and total vector domination. In vector domination one seeks a small subset S of vertices of a graph such that any vertex outside S ...
NP-hardness of decoding quantum error correction codes
NP-hardness quantum error correction codes
2010/10/18
Though the theory of quantum error correction is intimately related to the classical coding theory,in particular, one can construct quantum error correction codes (QECCs) from classical codes with the...
Hardness of k-Vertex-Connected Subgraph Augmentation Problem
Network survivability Graph connectivity
2012/12/3
Given a k-connected graph G = (V ,E) and V 伡 V , k-Vertex-Connected Subgraph Augmentation Problem (k-VCSAP) is to find S 伡 V \ V with minimum
cardinality such that the subgraph induced by V 伨 S ...
Silicon Photo-Multiplier radiation hardness tests with a beam controlled neutron source
Silicon Photo-Multiplier beam controlled neutron source
2010/3/16
We report radiation hardness tests performed at the Frascati Neutron Generator on silicon Photo-Multipliers, semiconductor photon detectors built from a square matrix of avalanche photo-diodes on a si...
Radiation hardness of CMS pixel barrel modules
LHC super LHC CMS tracking pixel silicon radiation hardness
2010/3/15
Pixel detectors are used in the innermost part of the multi purpose experiments at LHC and are therefore exposed to the highest fluences of ionising radiation, which in this part of the detectors cons...
Effects of Plasma Immersion Ion Implantation (PIII) of Nitrogen on Hardness, Composition and Corrosion Resistance of Ti-6Al-4V Alloy
Corrosion Hardness Plasma immersion ion implantation Ti-6Al-4V X-ray diffraction
2010/9/29
Ti-6Al-4V samples have been treated by PIII processing at different temperatures (400-800 ° C), treatment time (30-150 min) and plasma potential (100 and 420 V). Hardness measurements results showed a...

Vickers' micro hardness Cold-worked crystals Annealed crystals Zone-melting method
2010/4/9
InBi0.85Sb0.15 single crystals have been grown by zone-melting method. The growth velocity was 0.8 cm/h and the freezing interface temperature was 35 °C/cm. A Vickers' projection microscope was used f...
