Adulterations of olive oil are performed by adding seed oils to this high-quality product, which cheaper than oils. Food safety controls have been established the European Union avoid these episodes. Most methodologies require expensive equipment, time-consuming procedures, and expert personnel execute. Near-infrared spectroscopy (NIRS) technology has many applications in food processing industry. It analyzes quality parameters along chain. Using principal component analysis (PCA),...
Abstract A novel and simple methodology is introduced that allows accurate highly sensitive detection of microRNAs (miRNAs), taking advantage an amplification strategy based on multicomponent nucleic acid enzymes (MNAzymes), combined with a fluorescence resonance energy transfer (FRET) phenomenon. For this purpose, fluorescent dye (FAM) has been selected as donor, while gold nanoparticles (AuNPs) are employed acceptors, located close to each other through hybridisation the substrate. The...
A novel single-stage high-power-factor electronic ballast is presented in this paper. The obtained from the integration of a buck-boost converter and half-bridge LC resonant inverter. features lamp power regulation against line voltage fluctuations together with high factor dimming capability. steady-state analysis performed low-frequency model input stage derived. design example, including closed-loop circuitry, also presented. Finally some experimental results lab prototype are shown.
The development of a novel computer writing system based on eye movements is introduced herein. A these characteristics requires the consideration three subsystems: (1) hardware device for acquisition and transmission signals generated by movement to computer; (2) software application that allows, among other functions, data processing in order minimize noise classify signals; (3) graphical interface allows user write text easily screen using only. This work analyzes subsystems proposes...
The eye acts as a dipole between the cornea (positive potential) and retina (negative which causes an electric field around eyeball. Therefore, when humans make saccadic movements, they generate signals relative to this potential called electrooculography (EOG) signals. These can be measured by placing electrodes near eye. Different electrode configurations employed acquire EOG properties of these change depending on number placement electrodes. paper presents comparative study used measure...
Electrooculography is a technique for measuring the corneo-retinal standing potential of human eye. The resulting signal called electrooculogram (EOG). primary applications are in ophthalmological diagnosis and recording eye movements to develop simple human–machine interfaces (HCI). electronic circuits EOG conditioning well known field instrumentation; however, specific characteristics make careful design necessary. This work devoted presenting most important issues related an analog...
Electrooculogram (EOG) is the measurement of biopotential generated by eye movement. These signals are crucial for people with severe motor disabilities because they rarely suffer alterations in Therefore, correct classification these could find application design simple user interfaces that allow independence and communication skills. This paper presents a comparison main techniques literature control EOG-based human–computer (HCIs). Static threshold, K-nearest neighbor (KNN), artificial...
Abstract MicroRNAs (miRNAs) represent a class of small noncoding RNAs that are considered novel emerging disease biomarkers in variety afflictions. Sensitive detection miRNA is typically achieved using hybridization-based methods coupled with genetic amplification techniques. Although their sensitivity has improved, techniques often present erroneous results due to complexity. In addition, the use these usually linked application protein enzymes, activity which dependent on temperature and...

The method is based on optical measurements of the discharge arc path. With aid a dual lens projection system, relative light intensity at different points are guided by fiber optic to photodiode array. These statistically analyzed identify when occurs....
Ataxias are a group of neurodegenerative disorders characterized by cerebellar dysfunction that cause irregularities in the rate, rhythm, amplitude, and force voluntary movements. The electrooculogram (EOG) may provide clues about ataxic because most these patients have difficulty with visual tracking fixing their gaze. Using electrodes, EOG records biopotentials generated eye In this paper, three surface electrodes placed around socket, movements acquired using commercial bioamplifier...
Photoinduced fluorescence enhancement of colloidal quantum dots (QDs) is a hot topic addressed in many studies due to its great influence on the bioanalytical performance such nanoparticles. However, understanding this process not simple task, and it cannot be explained by general mechanism as greatly depends QDs' nature, solubilization strategies, surrounding environment, etc.
