BACKGROUND Several studies have evaluated accuracy of intraoral scanners (IOS), but data is lacking regarding variations between IOS systems in the depiction of the critical finish line and the finish line accuracy. The aim of this study was to analyze the level of finish line distinctness (FLD), and finish line accuracy (FLA), in 7 intraoral scanners (IOS) and one conventional impression (IMPR...

forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. in this research, forming limit diagram (fld) of ss304l sheet was obtained by abaqusfinite element software. in practice, the experimental determination of a forming limit curve is a very time-consuming procedure which requires special and expensive equipment. forming limit di...

The occurrence of ochratoxin A (OTA) and aflatoxins (AFs) in liquorice products made in Italy was surveyed. Twenty-eight samples of dried liquorice extract and fifty-four of liquorice confectionery (liquorice content between 2 and 10%) were collected from retail outlets located in northern Italy. After extraction and purification through an immunoaffinity column, OTA and AFs were analysed using...

The deadline assignment problem arises in distributed systems where each subtask composing a distributed task must receive a local deadline such that the task end-to-end deadline is met. It also arises in multi-hop networks where the maximum sojourn time of a flow on each visited node must be bounded by a local deadline that allows the flow end-to-end deadline to be met. We first formalize the ...

Nursing staff that work with patients with frontal lobe dementia (FLD) experience challenges that may lead to physical and psychiatric distress. The aim of this study was to capture the feelings, experiences, and reflections of the health staff regarding interactions with and caring for patients with FLD and to highlight what it means for health staff to care for patients with FLD through their...

background and objectives: a method was developed and validated for determining 15 polycyclic aromatic hydrocarbons (pahs) in refined olive and refined pomace olive oils using high performance liquid chromatography coupled with a fluorescence detector. materials and methods: the sample preparation involved liquid–liquid extraction with organic solvent and low temperature clean-up. the low tempe...

OBJECTIVES Metabolically healthy obese (MHO) phenotype describes an obese state with a favorable metabolic profile. However, the prognosis of this subpopulation remains controversial. We aimed to examine whether MHO phenotype is associated with progression of atherosclerotic activity, reflected as the changes in coronary artery calcification (CAC) over time. If so, we sought to determine the ro...

This paper presents a new method for combining Fisher’s Linear Discriminant (FLD) and Multi Layer Perceptron (MLP) for face detection. The input patterns are first clustered into 10 face and 10 non-face clusters using K-means algorithm. Then, the FLD coefficients are calculated to obtain the optimal projection of face and non-face images. For each 19×19 pixel window, only 19 FLD coefficients ar...
