investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Nanoparticles-based Electrochemical Biosensor for Single Bacterium Detection by Redox Signal Amplification
In this work, we report a portable microfluidic chip based on Si-Porous-Pt MSNs(Mesoporous Silica Nanoparticles) -enhanced electrochemical detection for single-bacteria diognostic. The possibility of single-bacteria detection is realized here by using electroactive molecules modified on Si-Porous-Pt MSNs(Mesoporous Silica Nanoparticles) to detect and differentiate Staphylococcus aureus and Pseu...
متن کاملIn situ Detection of a Single Bacterium in Complex Environment by Hyperspectral CARS Imaging
Detection of bacteria is essential for clinical diagnosis of infectious disease and food safety purposes. However, it is still a challenging task to rapidly detect bacteria, especially in their natural environment. By fiber-laser based hyperspectral coherent anti-Stokes Raman scattering (CARS) imaging, we showed that bacteria can be detected in a single cell level using spectral focusing in the...
متن کاملDetection of a Brucella-like (Alphaproteobacteria) Bacterium in Boophilus spp. (Acari: Ixodidae) from Iran
Ticks harbor many pathogenic, as well as endosymbiotic and non-pathogenic agents. They are host of a variety of as yet unidentified microbes that continue to be described. In the present study, a Brucella-like bacterium was detected in a Boophilus tick by PCR amplification of a partial fragment of 16S rRNA locus followed sequencing. Our results show that the members of the genus Boophilus may a...
متن کاملDetection of Polymer Brushes developed via Single Crystal Growth
Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. The designed experiments demonstrated that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and co...
