Medium access delay evaluation for distributed queueing dual bus (DQDB) MAC protocol
… medium access delay. In this paper a mathematic model is formulated to describe this detrimental behavior of DQDB. The access control method is first modeled as a M/G/1 queueing system with a single priority level, then it is remodeled as a non-preemptive priority system with three …

On the Rayleigh -Brillouin scattering in air
… were taken on 31 July 2002.</p><p>A widely used mathematic model---the S6 model---is fitted to the measured RBS spectra. The discrepancies between the measured temperature from the RayleighBrillouin spectra and from the radiosonde, combined with the discrepancies between the model and the …

Simultaneous collection of sulfur dioxide and nitrogen oxides via spray drying: Using sodium-based and calcium-based sorbents with select additives
… sorbents with and without select additives. A mathematic model, SPRAYMOD-Y, accounting for the hygroscopicity and solubility of spray-dryer sorbents was developed to predict the simultaneous removal efficiencies of SO$\sb2$ and NO in a spray dryer. SPRAYMOD-Y considered the gas-phase …

The integration of pumped hydro storage systems into PV microgrids in rural areas
… to batteries. The components of the system are modelled to consider losses of the system accurately. The mathematic model developed in this project assists the management system to make more efficient decisions. The proposed storage is integrated into a farmhouse that has a PV pumping system …

Non-Invasive Eradication of Biofilm on Metal Implants Using Alternating Magnetic Fields (AMF) and Antibiotics
… to metal implants were studied separately. A mathematic model was built to describe the response of biofilm to heat based on Arrhenius equation in order to study the responses of various strains to heat. Also, the synergistic effect of heat and antibiotics was observed towards biofilm …

Risk Assessment of Listeria monocytogenes in Ready-to-eat Meat from Plants to Consumption
… 3). This research developed a comprehensive model that simulated the entire processes of RTE food production, taking into account potential transfer and growth of L. monocytogenes in RTE meat and poultry products. This plant-to-consumption model analyzed the effectiveness of the three …

Gas fluidization of nanoparticles
… using both experimental measurements and modeling. Secondly, the effect of introducing certain external force fields on nanoparticle fluidization is experimentally investigated. Two external force fields were applied: sound waves from a loud speaker (acoustic assistance) and in-bed magnets …

Geographic Migration and Evolution of Streptococcus pneumoniae
… from South Africa (2000-2014) I developed models to reconstruct spread. I implemented simple statistical frameworks which can account for variable surveillance in both space and time. I also pair detailed human mobility data from Facebook users with genomic data within a mechanistic model …

Bipolar metal oxide thin film diodes
… has been mostly unexplored. The simple mathematic model presented in this work shows that the charge carrier injection is possible with the proposed p-n heterojunction configuration, an important design requirement for heterojunction bipolar transistors which is the long-term goal of …
