In order to achieve high efficiency, multimedia source coding usually relies on the use of predictive coding. While more efficient, source coding based on predictive coding has been considered to be more sensitive to errors during communication. With the current volume and importance of... READ MORE
A new workflow to produce dimensionality reduced manifold coordinates based on the improvements of landmark Isometric Mapping (ISOMAP) algorithms using local spectral models is proposed. Manifold space from nonlinear dimensionality reduction better addresses the nonlinearity of the hyperspectral data and often has better per-... READ MORE
This thesis proposes and explores a new technique to double the frequency of a RF-over-fiber signal in a linear fashion. The technique is based on combining the output of a well-known, commercial decide (the Mach Zehnder Modulator) in a new fashion that has not been... READ MORE
Computer networks are becoming more complex as the reliance on these network increases in this era of exponential technological growth. This makes the potential gains for criminal activity on these networks extremely serious and can not only devastate organizations or enterprises but also the... READ MORE
The lifecycle of a system is dependent on the system design. However, the concern with quality has been stressed mostly during its production and use. The understanding of the system variability generated by noise variables shifted the quality focus to the design phase. The... READ MORE
As a droplet containing colloidal material dries on a surface, the suspended particles are deposited onto it. Aqueous colloidal droplets often leave the majority of particles at the periphery of the deposition area. This phenomenon is known as the coffee ring effect, and it... READ MORE
Colorectal cancer (CRC), with multifactorial influences of genetic, molecular, inflammatory, and environmental factors, is a leading cause of cancer-related deaths. Due to the high diversity and concentration of microbes found in the human colon, the microbiome has become a prime suspect of being a... READ MORE
Introducing nucleic acids into mammalian cells is a crucial step to elucidate biochemical pathways, modify gene expression in immortalized cells, primary cells, and stem cells, and intoduces new approaches for clinical diagnostics and therapeutics. Current gene transfer technologies, including lipofection, electroporation, and viral delivery,... READ MORE
Various field portable goniometers have been designed to capture in-situ measurements of a material’s bi-directional reflectance distribution function (BRDF), each with a specific scientific purpose in mind.[1, 2, 3, 4] The Rochester Institute of Technology’s (RIT) Chester F. Carlson Center for Imaging Science recently... READ MORE
Open Microchannel Manifold (OMM) with taper has proved instrumental in enhancing heat transfer performance in flow boiling while keep the pressure drop to a minimum. This makes it applicable in developing a low pressure drop system like a thermosiphon loop. To this end, a... READ MORE
The spectral signatures of vehicles in hyperspectral imagery exhibit temporal variations due to the preponderance of surfaces with material properties that display non-Lambertian bi-directional reflectance distribution functions (BRDFs). These temporal variations are caused by changing illumination conditions, changing sun-target-sensor geometry, changing road surface properties,... READ MORE
Galaxy clusters are the largest gravitationally bound systems in the Universe and often host the largest galaxies (known as the brightest cluster galaxies (BCG)) at its centers. These BCG’s are embedded in hot 1-10 keV X-ray gas. A subset of galaxy clusters known as... READ MORE
State of the art triple junction solar cells have achieved in excess of 43% efficiency. In order to extend this beyond a multijunction-only design, novel approaches to photon conversion must be sought and realized. Two novel mechanisms, bandgap engineering and absorption from an intermediate... READ MORE
Functionally Graded Materials (FGMs) are characterized by a continuous variation in the composition of parent materials through the work piece volume. This gradual change in material composition is aimed at improving mechanical, thermal and/or electrical properties of the material. FGMs are being increasingly used... READ MORE
The use of computational fluid dynamics (CFO) to predict red blood cell trauma (hemolysis) in blood pumps based on their exposure to turbulent stresses has increased in recent years. The U.S. Food and Drug Administration (FDA) has initiated a project to determine the fidelity... READ MORE
