A Global Sensitivity Analysis Of Photochemical Models Used For Predicting Tropospheric Ozone, Daniel Wimer

Theses

The Clean Air Act requires the use of complex photochemical models to predict future ozone concentrations and the impact of current and future regulations. In many instances uncertainty in the data input parameters used to operate these models results in uncertainty in the prediction of future air quality. The degree of this uncertainty is often greater than the degreee of air quality improvements proposed by regulations. This study evaluates the sensitivity of a photochemical model to predict future ozone air quality with respect to the uncertainty of several critical input parameters. These parameters are: Transported ozone (ozone aloft) Biogenic emissions …

Evaluation Of The Change On Water Vapor Transmission Rate Of Different Polypropylene Films In Contact With D-Limoneme And The Effect Such Changes Have On The Shelf Life Of Confectionary Products., Anna Romero

Theses

This paper discusses the changes observed in Water Vapor Transmission Rate (WVTR) of three plastic films while exposed to different concentrations of d-limoneme. The concentration of d-limoneme on the films was determined by means of Headspace Gas Chromatography and Mass Spectrometry. The Water Vapor Transmission rate of all films was determined by means of a MOCON-Water Vapor Permeation Analysis System Permatran-W 3/31. It was observed that d-limoneme affected the films in two ways: at lower concentrations, the WVTR decreased but, after certain concentration was reached, the WVTR increased. These results explain the shortened shelf-life of candies containing d-limoneme which are …

Adaptive Radio Resource Management For 2.5g Cellular Networks, Ken Murray

Theses

Recent years have seen a dramatic increase in demand for mobile communication services and with the introduction of 2.5G services such as general packet radio service, this trend is expected to increase further. These new services will introduce highly dynamic tele-traffic variations due to the inherent variability in resource usage of the new data services. The net effect will be considerable increase in load on the available radio resources. The currently employed fixed channel allocation scheme lacks the flexibility to support such traffic variations. A plethora of dynamic channel allocation schemes have been proposed in the past in an effort …

The Potential For Public Opinion To Generate Change In Policy Formation, Peter M. Roguszka

Theses

Towards the end of the Twentieth Century there were a number of examples of change to public policy that were not the product of political debate and public consideration. Rather, they appear to have originated in another less visible, and therefore less open to critique manner. It is argued that it is changes to the general thrust of public opinion that have given validity to these policy changes. The ways in which changes to public opinion are caused to change and by whom are investigated and a theory of 'Australian Public Opinion Change' is developed. This theory is applied to …

Analyzing The Costs/Tradeoffs Involved Between Layer 2, Layer 3, Layer 4 And Layer 5 Switching, Gautam Kapur

Theses

The switching function was primarily entrusted to Layer 2 of the OSI model, i.e. the Data Link Layer. A Layer 2 switch performs forwarding decisions by analyzing the MAC (Media Access Control) address of the destination segment in the frame. The Layer 2 switch checks for the destination address and transmits the packet to the appropriate segment if the address is present in its table of known destinations. If the entry for that address is not present, the switch then forwards the packet to all segments except the one on which it came from. This is known as flooding. When …

Band Selection And Algorithm Development For Remote Sensing Of Wildfires, Andrew Fordham

Theses

The environmental damage and global change caused by wildfires are fast becoming issues of local, regional and global concern. Remote sensing techniques are an ideal tool to use for monitoring these threats. Unfortunately, most existing satellites were built for other purposes and are less than ideal for the problems associated with detecting, assessing and monitoring fires. This thesis examines the phenomenology of fires and rank orders several non-traditional detection strategies that have the promise of being more cost effective and less susceptible to false alarms than existing satellite systems and algorithms. The possibility of detecting fires with multi-band "color" measurements …

Derivation Of The Required Elements For A Definition Of The Term Middleware, Maya Mathew

Theses

Thirteen contemporary definitions of Middleware were analyzed. The definitions agree that any software that can do the following should be classified as Middleware (1) provide service that provides transparent application-to-application interaction across the network, (2) act as a service provider for distributed applications, and (3) provide services that are primarily used by distributed applications (e.g., RPCs, ORBs, Directories, name-resolution services, etc.) Most definitions agree that Middleware is that level of software required to achieve platform, location, and network transparency. There is some discrepancy about the OSI levels at which middleware operates. The majority of definitions limit it to levels 5, …

Intermittent Noise Sampling And Control Strategies In The Hospital Environment, Rosarito M. Guerrero

Theses

Noise in the hospital environment can have negative effects on both patients and hospital staff. Unwanted noise can be disturbing and often annoying thus, interfering with patients' sleep and obstructing work performance of the hospital staff. A research study was conducted in the hospital unit to identify and develop methods of intervention for intermittent noise and their source. Routine staff work activity generated noise levels above EPA hospital noise recommendations. A sound level meter and video camera was used to capture noise between the work-shifts. The video camera captured digital readings generated by the sound level meter which, helped identify …

Reductive Amination Of (Alpha) - Amino Acids: Solution - Phase Synthesis, Rohini D'Souza

Theses

Preparation of a small library of secondary amino acids was achieved by solution-phase organic synthesis using reductive amination reactions with selected cc-amino acids and aromatic aldehydes. Reductive amination employing sodium triacetoxyborohydride instead of sodium cyanoborohydride was found to give shorter reaction times and much safer byproducts. With less sterically hindered a-amino acids, direct reductive amination generally yielded the bisalkylated product. However, monoalkylation was achieved by adopting an indirect reductive amination route. Reaction mixtures were characterized by HPLC and LC-MS, resulting in the synthesis of a 21 compound library.
