Detection of tool breakage is very important for automated machining operations. This paper presents a negative-selection algorithm for tool breakage detection. The method is inspired by the defense mechanism of the immune system, which discriminates between self and non-self. Here self is deened to be normal cutting operations and non-self is any deviation beyond allowable variation of the cut...

The Centre National de la Recherche Scientifique (CNRS) is the biggest public research institute in France. The activity fields cover a large spectrum from social science to mathematics including physic and biology. Some laboratories are directly managed by the CNRS but many others are joint structures with a university or even a private company. With 1300 laboratories the CNRS is a split organ...

Court-mandated downsizing of the CA prison system has led to a redistribution of detainees from prisons to CA county jails, and subsequent jail overcrowding. Using data that is representative of the LA County jail system, we build a mathematical model that tracks the flow of individuals during arraignment, pretrial release or detention, case disposition, jail sentence, and possible recidivism d...

OBJECTIVE To assess plantarflexion moment and hip joint moment after-effects following walking on a split-belt treadmill in healthy individuals and individuals post-stroke. DESIGN Cross-sectional study. SUBJECTS Ten healthy individuals (mean age 57.6 years (standard deviation; SD 17.2)) and twenty individuals post-stroke (mean age 49.3 years (SD 13.2)). METHODS Participants walked on an i...

Abstract The joint between different lightweight materials plays a significant role in multi-material design of structural components for the automotive industry, aiming to reduce vehicle’s weight without compromising performance or safety. Yet, conventional mechanical joining technologies metals and Carbon Fibre Reinforced Polymers (CFRP) result either hole being drilled composite material, le...

A novel multicolor fluorescence in situ hybridization approach, using an alpha satellite probe which labels the centromeric region on chromosome 1 and a classical satellite probe which targets an adjacent breakage-prone region (1q12), has been used to detect both hyperdiploidy and chromosome breakage in interphase human cells. With the use of this technique significant increases in chromosomal ...

BACKGROUND Previous research reveals an association between traumatic stress and an increased risk for numerous diseases, including cancer. At the molecular level, stress may increase carcinogenesis via increased DNA damage and impaired DNA repair mechanisms. We assessed DNA breakage in peripheral blood mononuclear cells from individuals with post-traumatic stress disorder (PTSD) and measured t...

B susceptibility and hardness of three yellow dent corn hybrids were determined for kernels separated into 6 size and shape categories and equilibrated to 12.3 and 14.7% moisture (wet basis). Measurements for breakage susceptibility by severe impact from the Wisconsin Breakage Tester (WBT) and by a grinding action from the Stein Breakage Tester (SBT) were determined by sieve and by a green dye ...

background: this study has used biomarker of exposure-effect continuum to examine the biological characteristics of organophosphate (op) toxicity and its genotoxic effect among rice farmers.   materials and methods : a cross-sectional study was conducted among 160 pesticide exposed rice farmers and 160 adults from the fishing village as the unexposed group. they share the common socio-economica...

Using DEM (Discrete Element Method), a model is presented to simulate the breakage of two-dimensional polygonshaped particles. In this model, shapes of the particles generated after breakage are predefined and each uniform (uncracked) particle is replaced with smaller inter-connected sub-particles. If the bond between these sub-particles breaks, breakage will happen. With the help of this model...
