Fitting phase type distribution to service process with sequential phases por Nanda, Ankita

“…The work of this thesis is concerned with fitting Hypo-exponential and Erlang phase type distributions for modeling real life processes with non-exponential service time. There exist situations where exponential distributions cannot explain the distribution of service time properly. …”

Estudio de los efectos de la estrategia de inyección piloto sobre el proceso de mezcla en un motor diesel. por Borrego Alvarez, Sergio

“…En la segunda parte, se ha estudiado el efecto de la estrategia de inyección piloto sobre el proceso de mezcla, mediante la variación del Dwell time, y al igual que la primera parte, se caracterizaron los parámetros macroscópicos del chorro diésel, observando que la inyección piloto se comporta de manera similar a una inyección simple, mientras que la inyección principal se ve afectada por el valor del Dwell time. …”

Structural and vibrational study of PCBM por Tlahuice Flores, Alfredo, Mejía Rosales, Sergio

“…To date, all the infrared spectra reported are experimental, mainly because of the calculations needed to study these structures are highly time-consuming. In this report we address for the first time the infrared spectrum calculation of PCBM with Cs symmetry by using the PW91/dnp level as implemented in the Dmol3 code. …”

Phenol adsorption onto coffee waste - granular activated carbon: kinetics and equilibrium studies in aqueous solutions por Díaz de León Garza, María de la Luz, Soto Regalado, Eduardo, Loredo Cancino, Margarita, Cerino Córdova, Felipe de Jesús, García Reyes, Refugio Bernardo, Dávila Guzmán, Nancy Elizabeth, Loredo Medrano, José Ángel

“…abstract In this research, the production of granular activated carbon from coffee waste (CW) by chemical activation with zinc chloride was studied by using a 23 factorial design with the three responses (surface area, yield, and hardness) and studying three factors (the activation temperature, activation time, and impregnation ratio). The findings expose that after the experimental design, the highest response values were achieved at an activation temperature of 600°C, an activation time of 40 min, and an impregnation ratio of 1.5 g ZnCl2 g–1 CW. …”

Cultural factors associated with healthful behaviors in India por Díaz, Héctor Luis

“…Such factors include: gender discrimination and the resulting inability of women to make decisions impacting their own health, tensions between Indian folk medicine and western medicine, social discrimination and the resulting inequitable access to health services by minority groups, culturally dictated forms of communication, the role of spirituality and religion, their culturally prescribed notion of time and attitudes towards time, group orientation and reliance on the family and friends during health crises. …”
