Show moreA system and method of channel estimation for a multi-user broadband wireless channel estimation in multiple antenna receiver systems use a specifically selected delay in the pilot symbol sequence portion of the transmission which is a multiple of the minimum Cyclic Prefix delay length. This insures that the time-frequency slot information bursts will always be separated in the time domain. A matched filter output in the receiver is formed by multiplying each pilot symbol by the conjugate of the training symbols of the first user. Estimation of the channel response may include three different versions of the efficient estimation calculations, namely Constrained Inverse Deconvolution, Iterative Low Complexity, and Extrapolated Matched Filter estimations. The first two methods do not require matrix multiplication (using only Fourier transforms), while the third method utilizes a smaller matrix multiplication than previously taught. Hardware considerations are also reduced due to the lack of a need for extensive matrix by matrix calculations.

Show moreTo provide confinement in a porous medium in the earth, a limited region of the porous medium is heated to drive substantially all of the free water from open spaces of the medium in the region. After heating, liquid material is introduced into the open spaces in the medium, which liquid material will set into a substantially solid structure. The liquid material is then set in the open spaces to form a substantially solid structure in the medium in the region.

Show moreThermal stability has been proposed as a criterion to assess the allergenic potential of genetically modified foods, but there is a lack of information on the relative thermal stability of food allergens vs. nonallergenic proteins. This study compared the thermal stability of several paired food allergens and nonallergenic proteins by measuring the changes in their solubility, antigenicity and thermodynamic properties after thermal treatment using BCA total protein assay, inhibition ELISA assay, Differential Scanning Calorimetry and Far-UV Circular Dichroism Spectroscopy. The selected protein pairs included bovine α-lactalbumin (allergen) vs. human α-lactalbumin (nonallergen), peanut lectin (allergen) vs. concanavalin A (nonallergen), soybean trypsin inhibitor (allergen) vs. lima bean trypsin inhibitor (nonallergen). With respect to protein solubility, a greater thermal stability was observed for: (1) bovine α-lactalbumin (bovine ALA) when it was autoclaved in water compared with human α-lactalbumin (human ALA) (2) peanut lectin when it was boiled or autoclaved in water compared with concanavalin A (ConA) and (3) soybean trypsin inhibitor (STI) when it was boiled in water or PBS, or autoclaved in water compared with lima bean trypsin inhibitor (LTI). Regarding TM values determined by DSC: (1) bovine ALA was more thermally stable than human ALA under both dry-heat treatment and moist-heat treatment (2) ConA was more thermally stable than peanut lectin during moist-heat treatment, while a greater thermal stability was observed for peanut lectin when the protein was under dry-heat treatment (3) LTI was more thermally stable than STI during heating in water or under dry-heat treatment, while a greater thermal stability was observed for STI when the protein was heated in PBS. Based on CD analyses, (1) bovine ALA was more thermally stable than human ALA (2) peanut lectin was more thermally stable than ConA (3) STI and LTI showed similar thermal stability. With respect to antigenicity, a greater thermal stability was observed for: (1) human ALA when it was autoclaved in water compared with bovine ALA (2) ConA when it was boiled or autoclaved in water, or under dry-heat treatment at 176℃ compared with peanut lectin (3) STI when it was autoclaved in PBS compared with LTI. In summary, allergens tended to be more thermally stable than nonallergenic proteins with respect to solubility, but there was no consistent trend in the relative thermal stability of these protein pairs regarding the antigenicity or the TM values. No correlation between thermal stability of the proteins and their allergenic potential was observed.ConA (3) STI and LTI showed similar thermal stability.

Show moreDue to growing concerns over the availability of non-renewable petroleum products and the increasing emphasis on protecting our environment from green house gas emissions, plug-in hybrid electric vehicle and hybrid electric vehicles have been gaining increasing popularity over recent years. This has led to the design of advanced drive systems using different electric motors such as BLDC, PMSM, IM and SRM. An electric motor/generator requires controller that not only has a strong I/O control function, but also high speed signal processing ability for realizing real time control. Therefore, a DSP (Digital Signal Processors), which integrates flexible multiple PWM signal generator, high speed high precision ADC and encoder interface for motor speed and position feedback, is considered as one of the strongest controllers for electric motor control. Owing to a growing emphasis on identification, interference, and communication of security services of drive train in intelligent PHEVs and HEVs, a DSP can also be used to identify and isolate security issues in the integrity of the drive train in PHEVs and EVs. This thesis has two main contributions: a) it focuses on the development of an embedded controller using TMS320LF2812 DSP to realize two quadrant control of the BLDC; and b) it develops an automotive test bench to identify and investigate some potential security issues using the embedded controller’s eCAN communication function.

Show moreWater shortages will be a global problem by the year 2025. With the Great Lakes Basin accounting for 95% of the fresh water in the United States it will soon become our most valuable natural resource. In re-defining urban relationships to the Great Lakes a healthy, ecologically stable, and regenerative water system can become our greatest national asset. Providing a prototype solution for one of these urban areas (Traverse City, MI) may set a precedent for long term protection of the Great Lakes.

Show moreAn electrohydrodynamic conduction liquid pumping system having a vessel configured to contain a liquid therein, a single pair or multi-pairs of electrodes disposed in a circularly spaced apart relationship to each other inside the vessel and configured to be oriented in the liquid. A power supply is coupled to the electrodes and configured to generate electric fields in-between each electrode pair to induce a net radial pumping of the liquid. A heat source is provided to produce heat sufficient to boil and vaporize the liquid while non-vaporized liquid moving toward the heat source prevents over-heating of the heat source. A heat sink is configured to have a operating temperature below the vaporization temperature of the liquid so that contact of the vapor with the heat sink will condense the vapor into a liquid to replenish the liquid supply moving toward the heat source.

Show moreForced periodic operation of tubular reactors can increase conversion and yield if proper operating conditions and forcing policies are selected. A numerical approach is proposed for computing the effects of periodic input forcing by a shooting algorithm. Such computational tools permit the assessment of the benefits of forced periodic operation of a specific reactor system and the identification of the ranges of operating conditions where forced periodic operation is beneficial. This information provides valuable insight for planning detailed experimental studies. Determining the influential input variables and bracketing the ranges of the operating conditions for improving reactor performance will reduce significantly the experiments needed for selecting the most favorable reactor operation policies. The application of the numerical algorithm is illustrated by assessing the benefits of forced periodic operation to a CO oxidation reactor model. The results reveal substantial improvement in performance with slow cycling in feed concentration.
