Here To See It

Benjamin J. Chase’s Here To See It is a collection of contemporary poetry plotted across the hours of a day and the respective stages of life. A mix of lyrical and narrative musings, the book houses a wide variety of poetic forms (including a translation, sonnets, ekphrastic meditations, and free-verse experiments) on an even wider variety of subjects. A diverse collection, Here To See It is a series of reflections on the formal and informal moments that make up a lifetime

Finding Spanning Trees in Strongly Connected Graphs with Per-Vertex Degree Constraints

In this project, I sought to develop and prove new algorithms to create spanning trees on general graphs with per-vertex degree constraints. This means that each vertex in the graph would have some additional value, a degree constraint d. For a spanning tree to be correct, every vertex vi in the spanning tree must have a degree exactly equal to a degree constraint di. This poses an additional constraint on what would otherwise be a trivial spanning tree problem. In this paper, two proofs related to my studies will be discussed and analyzed, leading to my algorithm for determining a spanning tree on strongly connected graphs. It is my hope that in the future this algorithm can be modified to apply to the general case

Photocurable Bioink for the Inkjet 3D Pharming of Hydrophilic Drugs.

Novel strategies are required to manufacture customized oral solid dosage forms for personalized medicine applications. 3D Pharming, the direct printing of pharmaceutical tablets, is an attractive strategy, since it allows for the rapid production of solid dosage forms containing custom drug dosages. This study reports on the design and characterization of a biocompatible photocurable pharmaceutical polymer for inkjet 3D printing that is suitable for hydrophilic active pharmaceutical ingredients (API). Specifically, hyaluronic acid was functionalized with norbornene moieties that, in the presence of poly(ethylene) glycol dithiol, Eosin Y as a photoinitiator, and a visible light source, undergoes a rapid step-growth polymerization reaction through thiol-ene chemistry. The engineered bioink was loaded with Ropinirole HCL, dispensed through a piezoelectric nozzle onto a blank preform tablet, and polymerized. Drug release analysis of the tablet resulted in 60% release within 15 min of tablet dissolution. The study confirms the potential of inkjet printing for the rapid production of tablets through the deposition of a photocurable bioink designed for hydrophilic APIs

Altitude dependence of atmospheric temperature trends: Climate models versus observation

As a consequence of greenhouse forcing, all state of the art general circulation models predict a positive temperature trend that is greater for the troposphere than the surface. This predicted positive trend increases in value with altitude until it reaches a maximum ratio with respect to the surface of as much as 1.5 to 2.0 at about 200 to 400 hPa. However, the temperature trends from several independent observational data sets show decreasing as well as mostly negative values. This disparity indicates that the three models examined here fail to account for the effects of greenhouse forcings.Comment: 9 pages, 3 figure

SSBBR-X: Candidate Engine for Concorde

Advances in each component of a low bypass ratio turbofan were considered to improve the performance for Concorde’s mission. The bypass fan will feature a multi-stage design intended to increase pressure ratio and exit velocity of the bypass air to speeds exceeding cruising speed. The multi-stage fan will allow a variable bypass design to be utilized for optimization in different flight regimes. Preliminary research suggests that using a bypass ratio of around 1.0 will be feasible to implement in the design. The exit nozzle will be a variable converging-diverging nozzle to allow for necessary mass flow at different velocities, which is now an industry standard. Compressors of the past have been high in weight with limited pressure ratios, but by using new technologies currently available and new materials proposed to be available, compressors can be lighter and have higher-pressure ratios per stage. Using a bladed disk (or blisk) alone can lead to a weight savings up to 30% and new materials have been proven to have higher operating temperatures, allowing for higher efficiency and thrust for the entire system. New research has proposed a redesign of the burner-turbine system which would reduce the turbine inlet temperatures as well as increase efficiency and thrust. This new system is the Inter-Turbine Burner (ITB) which adds a second combustion chamber in between the high and low-pressure turbine stages. The effect of an ITB is to burn the fuel from the first burner and use all the remaining oxygen in the system. The ITB system eliminates the need for cooling channels in the turbine blades, which subsequently eliminates the need for a cooling system and bleed valves. This reduces the high complexity and weight of turbines while simultaneously reducing the cost of manufacturing traditional blades. Traditional blades are made of superalloys that are manufactured by casting a one direction crystal structure in the metal. New methods for manufacturing blades have been proposed, consisting of using additive manufacturing and advancements in composite materials. Using composites and additive manufacturing, turbine blades can be made with a high tolerance to temperature, which will decrease the TSFC as well as cost. These systems were tested using parametric cycle analysis implemented in MATLAB, VuCalc, GasTurb13, and AxSTREAM to effectively compare their impact on the entire engine and gauge whether any combination of the new component technologies will be ready for a 2028 entry-into-service date. This analysis is a precursor to a different AIAA design competition with the purpose of designing engines to replace those on the Concorde aircraft. The results of this engine will be compared to Concorde’s original Olympus 593 engines to determine if better performance was achieved
