Description
In the last years of the twentieth century, while the narrative of women in other Latin American countries has received critical attention, Bolivian women's narrative has been widely ignored. The fact that the voice of Bolivian women in Latin American feminist discourse is rarely discussed in Latin American criticism is enough to justify the present study. This work focuses on three prominent Bolivian writers: Gaby Vallejos, Giovanna Rivero Santa Cruz, and Erika Bruzonic. The short stories of these three authors are characterized by accentuating certain telluric features revealed in the background of their feminine/feminist narratives. At the same time, based on the American and European feminist literary critique, this work analyzes the feminine/feminist themes mounted in the narrative of these authors. Gaby Vallejos, with a cinematic style, chronicles the life and customs of the "valluno" context, building a mosaic of different voices in dialogue. Her topics revolve around binaries: life-death, and pain and pleasure, voicing condemnation for a patriarchal society. Ericka Bruzonic deals with women and identity, memory and the breaking of lineage as an imposing structure. Her themes are built around the cosmopolitism of "paceña" urban life, and her voice transgresses the binomials established by a patriarchal society. Finally Giovanna Rivero Santa Cruz takes the life and customs of the Santa Cruz and the Guarani culture and her plots weave these elements reaching for myths and taboos, involving the reader into her stories. In this manner, her narrative makes an incursion into the conscious and unconscious realm of the readers questioning their wealth of moral and social values, their notions of heterosexuality, and sexual taboos. The three writers, with different narrative styles yet dialogical, narrate various experiences of women from different regions, social classes, ages, education, and sexual orientations. Our authors give high value to the word and the body embedded in the culture, thereby affirming their woman's voice as Bolivians and their literary presence in the context of Latin American literature.

Description
Las personas públicas de mujeres fuertes mexicanas generalmente se definen como desafiantes y contrarias a los roles sociales generalmente aceptados de las mujeres sumisas. Dichas personas públicas exigen atención y buscan incluirse en la cultura popular. Sin embargo, cuando se analizan mediante los rubros de la teoría queer, se revelan arquetipos heternormativos. Esta tesis examina cronológicamente la obra de tres cronistas mexicanos de los siglos XX y XXI, Salvador Novo, Carlos Monsiváis y Sara Sefchovich, analizando su retrato de mujeres fuertes que ocupan sitios urbanos públicos en la Ciudad de México. Se investigan los efectos sociales elitistas de las imágenes públicas de mujeres fuertes, revelando restricciones patriarcales de mujeres en espacios públicos y construcciones subsecuentes de personas públicas como exóticas y cosificadas, asimismo facilitando interacciones con una sociedad sumamente masculinista y machista. La falta de agencialidad social real se revela cuando el patriarcado se reafirma, a pesar de la índole disconforme de las mujeres retratadas. Los constructos de familia y de masculinidad exigen la existencia tanto del padre y del esposo ausentes como del hipermacho y de la acompañante mujer sumisa limitada a sitios privados. El retrato de mujeres fuertes en la obra analizada desnaturaliza la imagen de domesticidad, señalando que las mujeres mexicanas salen del hogar para ocupar sitios públicos en la Ciudad de México. Como la normalización del constructo de familia se cuestiona, la teoría queer se utiliza en una manera innovadora para analizar dichos retratos de mujeres fuertes y agencialidad sociopolítica.

Description
The mid-eighteenth century publication of national British folk collections like James MacPherson's Works of Ossian and Thomas Percy's Reliques of Ancient English Poetry, placed a newfound interest in the ancient literature associated with Northern/Gothic heritage. This shift from the classical past created a non-classical interest in the barbarism of Old Norse society, which appeared to closely resemble the Anglo-Saxons. In addition to this growing interest, Edmund Burke's seminal treatise, A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful, provided a newfound aesthetic interest in objects of terror. The barbaric obscurity and exoticism associated with the Norse culture provided the perfect figures to explore a Gothic heritage while invoking the terror of the sublime. This interest accounted for a variety of works published with Gothic themes and elements that included Old Norse pagan figures. Though a few scholars have attempted to shed light on this sub-field of Romanticism, it continues to lack critical attention, which inhibits a more holistic understanding of Romanticism. I argue that "Norse Romanticism" is a legitimate sub-field of Romanticism, made apparent by the number of primary works available from the age, and I synthesize the major works done thus far in creating a foundation for this field. I also argue that one of the tenets of Norse Romanticism is the newfound appreciation of the "Norse Woman" as a democratized figure, thus opening up a subversive space for dialogue in women's writing using the Gothic aesthetic. To illustrate this, I provide analysis of three Gothic poems written by women writers: Anna Seward's "Herva at the Tomb of Argantyr," Anne Bannerman's "The Nun," and Ann Radcliffe's "Salisbury Plains. Stonehenge." In addition, I supplement Robert Miles' theoretical reading of the Gothic with three philosophical essays on the empowerment of the imagination through terror writing in Anna Letitia Aikin (Barbauld) and John Aikin's "On the Pleasure Derived from Objects of Terror" and "On Romances" as well as Ann Radcliffe's "On the Supernatural in Poetry."

Description
Efficiency of components is an ever increasing area of importance to portable applications, where a finite battery means finite operating time. Higher efficiency devices need to be designed that don't compromise on the performance that the consumer has come to expect. Class D amplifiers deliver on the goal of increased efficiency, but at the cost of distortion. Class AB amplifiers have low efficiency, but high linearity. By modulating the supply voltage of a Class AB amplifier to make a Class H amplifier, the efficiency can increase while still maintaining the Class AB level of linearity. A 92dB Power Supply Rejection Ratio (PSRR) Class AB amplifier and a Class H amplifier were designed in a 0.24um process for portable audio applications. Using a multiphase buck converter increased the efficiency of the Class H amplifier while still maintaining a fast response time to respond to audio frequencies. The Class H amplifier had an efficiency above the Class AB amplifier by 5-7% from 5-30mW of output power without affecting the total harmonic distortion (THD) at the design specifications. The Class H amplifier design met all design specifications and showed performance comparable to the designed Class AB amplifier across 1kHz-20kHz and 0.01mW-30mW. The Class H design was able to output 30mW into 16Ohms without any increase in THD. This design shows that Class H amplifiers merit more research into their potential for increasing efficiency of audio amplifiers and that even simple designs can give significant increases in efficiency without compromising linearity.

Description
Class D Amplifiers are widely used in portable systems such as mobile phones to achieve high efficiency. The demands of portable electronics for low power consumption to extend battery life and reduce heat dissipation mandate efficient, high-performance audio amplifiers. The high efficiency of Class D amplifiers (CDAs) makes them particularly attractive for portable applications. The Digital class D amplifier is an interesting solution to increase the efficiency of embedded systems. However, this solution is not good enough in terms of PWM stage linearity and power supply rejection. An efficient control is needed to correct the error sources in order to get a high fidelity sound quality in the whole audio range of frequencies. A fundamental analysis on various error sources due to non idealities in the power stage have been discussed here with key focus on Power supply perturbations driving the Power stage of a Class D Audio Amplifier. Two types of closed loop Digital Class D architecture for PSRR improvement have been proposed and modeled. Double sided uniform sampling modulation has been used. One of the architecture uses feedback around the power stage and the second architecture uses feedback into digital domain. Simulation & experimental results confirm that the closed loop PSRR & PS-IMD improve by around 30-40 dB and 25 dB respectively.

Description
In this thesis, a digital input class D audio amplifier system which has the ability
to reject the power supply noise and nonlinearly of the output stage is presented. The main digital class D feed-forward path is using the fully-digital sigma-delta PWM open loop topology. Feedback loop is used to suppress the power supply noise and harmonic distortions. The design is using global foundry 0.18um technology.
Based on simulation, the power supply rejection at 200Hz is about -49dB with
81dB dynamic range and -70dB THD+N. The full scale output power can reach as high as 27mW and still keep minimum -68dB THD+N. The system efficiency at full scale is about 82%.

Description
With the establishment of "the special period in times of peace" in the nineties, there was in Cuba a series of transformations that affected its artistic and literary production. Therefore, gradually, a thematic opening emerged focused on deconstructing the idealized sociopolitical reality of the island allowing for the reformulation of the ways in which women were depicted. The main objective of this study is to initiate a dialogue with the short fiction produced during this period in order to shed light on the fragmentary representation of female characters. In regards to said objective, the approach selected centers on the observation and analysis of violence, humor and national memory as recurring thematic elements in the texts. With that finality, the aesthetic proposals present in the work of Aida Bahr, Ena Lucía Portela, and Marilyn Bobes, will be analyzed using current literary and cultural theory. Among these the most noteworthy are Josephine Gattuso Hendin's theory of violence and the representations of women, Henri Bergson's theory of humor, and the critical works of numerous scholars specializing in Cuban fiction produced in the last two decades. As has been concluded, through the protagonists and their discourse, thematic and stylistic components contribute to creating new representations of women allowing for new responses and ways of coexisting that cast doubt on the stereotype of the revolutionary woman. These components, likewise, question the relationship between the characters in the stories and the concept of nation, which in the words of Nara Araújo, will allow us to reveal the different ways of reading the world of the present generation. Therefore, through the analysis of the configuration of these reactionary representations, a contribution is made to the study of the current narrative produced by women in Cuba.
