The development of an low cost acquisition system of S-EMG signals which are reliable, comfortable for the user and with high mobility shows to be a relevant proposition in modern biomedical engineering scenario. In the study, the sampling capacity of the Arduino microcontroller Atmel Atmega328 with an A / D converter with 10-bit resolution and its reconstructing capability of a signal of surfa...

Nine new manganese(III) fluorophosphates have been synthesised hydrothermally in a fluoride-rich medium, through the use of MnF(3), HPF(6) and monovalent metal fluorides as reactants. Products have been structurally characterised using single crystal X-ray diffraction. Reaction in fluoride-rich conditions produces chain, layer and three dimensional framework structures containing new and unusua...

Bu çalışma, Sentinel 2A multispektral uydu görüntüsü kullanılarak jeolojik özelliklerin ortaya çıkarılmasına yönelik gerçekleştirilmiştir. Sivas ili Koyulhisar ilçesi sınırları içerisinde kalan çalışma alanında sedimanter ve volkanik kayaçlar yüzeylemektedir. Ayrıca, alanı, Türkiye’nin en önemli aktif fay zonlarından bir tanesi olan Kuzey Anadolu Fay Zonu (NAFZ) üzerinde konumlanmaktadır. Sarp ...

Performance, digestibility of nutrients, microbial nitrogen flow (MNF) and nitrogen efficiency (NE) inearly lactating Holstein cows were investigated by diet supplementation with sodium caseinate (CN).Multiparous lactating Holstein cows (n = 15) with an average body weight of 638 kg and 21 days in milkwere assigned to a completely randomized design (five cows per treatment) and fed a basal diet...

This study aims to improve heat transfer by utilizing Kelvin forces and inducing magnetic-induced convection in ferro-hydrodynamic convection, conjunction with nanoparticle migrations. The fundamental equations governing the conservation of mass, momentum, energy, mass were formulated as partial differential equations. As primary terms, model incorporated buoyancy, Lorenz, forces. In this conte...

Using results from adapting a multi-criteria decision support methodology for use by Multi-National Force, Iraq (MNF-I), this paper develops an argument for adopting a similar approach across the Department of Defense (DoD). While in Baghdad, the authors adapted a methodology to visually frame problems in a decision-matrix format and logically arrange courses of action for scoring against how w...

In order to providing the accuracy of spectral target detection in this research, we use three different procedures. They are decreasing noise and spectral correlation of Hyperspectral images by the use of algorithm MNF(Minimum Noise Fraction), compounding the detection algorithms by the use of ANFIS(Adaptive Neuro-Fuzzy Inference System) method and finally the spectral-spatial target detection...
