nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. in this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. in this modeling, three 2d models of tissue have been created: tissue, tissue including a tumor, and tissue ...

rapid and accurate identification of microorganisms have a significant impact on strategies and fish health management programs. hence, in this study a duplex pcr assay based on the 16s rrna gene for simultaneous detection of aeromonas hydrophila rticc 1032 and escherichia coli rticc 2325 from pure cultures, and challenged fish tissues was performed and their results were compared with the resu...

esters of phthalates, mainly applied as plasticizer, cause several human health and environment    hazards. phthalates are widely used in pharmaceutical products, cosmetics, as well as other plastic commercial products, and can penetrate in foods, water dusts, and air leading to ingestion and inhalation exposure followed by skin absorption for human. these compounds cause serious adverse effect...

there are various methods for the analysis of potassium sorbate and sodium benzoate in food products, but a rapid and reliable method for identification of these preservatives in doogh (an iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (hplc) utilized and followed by uv diode array detection of the two preservatives. the aim of this case study w...

in this study, detection and identification of common faults in industrial gas turbines is investigated. we propose a model-based robust fault detection(fd) method based on multiple models. for residual generation a bank of local linear neuro-fuzzy (llnf) models is used. moreover, in fault detection step, a passive approach based on adaptive threshold is employed. to achieve this purpose, the a...

fusarium oxysporum f. sp. lycopersici (fol) is the causal agent of vascular wilt in tomato, an important plant disease in iran. four monogenic resistance genes in tomato are used for identification of races of fol and their corresponding avirulence genes avr1, avr2 and avr3 were identified in pathogen one of which, avr2, is f.sp. specific. hence they can serve as reliable markers for racial ide...

objective: tooth decay is one of the most common chronic diseases in the world. after pit and fissures, enamel of proximal surface is the second region prone to rot. bitewing images are one of the most important diagnostic tools for the detection of caries . given the importance of accurate and timely detection of decay , the current study was aimed to evaluate the ability and skill of the fina...

abstract background: many disease susceptibility genes are large and consist of many exons in which point mutations are scattered throughout. scanning each exon individually represents a tedious task which can be time consuming and expensive. there has been increasing demand for rapid and accurate methods for full scanning of unknown point mutations in large multi-exon genes. gene assembling is...

hearing loss (hl) is the most frequent sensory defect present in 1 of every 500 newborns. in developed countries, at least 50% of cases are caused genetic factors, most often resulting in nonsyndromic hl (70%), which is usually autosomal recessive (80%). to date, fifty genes associated with autosomal recessive non-syndromic hearing loss (arnshl) have been reported.  the aim of this study was to...

In this paper, a boosting-based incremental hybrid intrusion detection system is introduced. This system combines incremental misuse detection and incremental anomaly detection. We use boosting ensemble of weak classifiers to implement misuse intrusion detection system. It can identify new classes types of intrusions that do not exist in the training dataset for incremental misuse detection. As...
