Designing neural network models that can attain results similar to those of humans on tasks like image-captioning and image-generation is a worthy goal in the overall pursuit of artificial general intelligence. Notwithstanding the tremendous recent progress in this area, current systems still cannot describe objects and scenes as creatively and accurately as humans. As a step in the direction of bridging this gap, this thesis proposes architectures and algorithms for generating high-quality, diverse outputs for the tasks of image-captioning and image-generation
From Jyoti to Jasmine: Mukherjee's Quest for Hybrid Identity in Jasmine
Get PDFAbstract: The present paper investigates the empowering force of
hybridity in female diasporant in Bharati Mukherjee’s outstanding novel
Jasmine. The novel depicts Jasmine’s journey of transformation from a
passive, traditional girl at the mercy of fate in a village in India to an active,
modern, and most importantly cross-cultural hybrid woman in America. All
through the novel, her identity is transformed in line with shifts in her name
from Jyoti to Jasmine to Jazzy to Jane. Accordingly, she stands in-between two
cultures, shuttles between identities, welds opposing identities, enters the third
space and emerges as a hybrid. The present study in the light of Homi Bhabha's
insights seeks to demonstrate that immigrating, experiencing displacement and
in-betweenness, and being positioned in the third space pave the way for
Jasmine’s becoming a hybrid and being liberated. Besides, the study is to
depict by creating a hybrid character, Bharati Mukherjee, the author, alludes to
her own very hybridity
Preliminary Assessment of Hydrogen Peroxide Gel as an Oxidizer in a Catalyst Ignited Hybrid Thruster
No full textIn regard to propulsion system applications, the stability of liquid propellants in long-term storage is of increasing importance, and this had led to a greater interest in gelation technology. As part of a preliminary test to determine the feasibility of using a gel propellant in a rocket with a catalyst bed, a hybrid rocket with a catalyst reactor using a gel propellant as an oxidizer was tested for the first time in this study. Experiments were conducted with two different oxidizers: one with liquid phase hydrogen peroxide and the other with gel phase hydrogen peroxide, as well as high-density polyethylene as fuel for a 250N class hybrid thruster performance test. The thruster was designed with the catalyst ignition system, and a catalyst was manufactured to be inserted into the catalyst reactor to facilitate oxidizer decomposition. While the test result with neat hydrogen peroxide indicated sufficient decomposition efficiency using a manganese dioxide/alumina catalyst and successful autoignition of the fuel via the decomposed product, gel hydrogen peroxide exhibited insufficient decomposition and there were difficulties in operating the thruster as a part of the catalyst was covered in the gelling agent. This preliminary study identifies the potential challenges of using a gel phase oxidizer in a catalyst ignited hybrid thruster and discusses the technical issues that should be addressed in regard to a gel propellant hybrid thruster design with a catalyst reactor.Space Systems Egineerin

No full textThis is two books bound together, each with a separate ISBN number and separate pagination. Each book has five stories, 12 to 22 pages in length. Both feature heavy paper and large print. The stories are well told. The first book contains these five: The Clever Fox and the Goat; TH; and GGE; The Hungry Fox and the Shepherds; and The Ungrateful Traveller. The first extends the usual fable by having the fox spend a full night in the well. In TH, the tortoise has a mantra: I always finish what I have started (19). The hare thinks There would be no harm in sleeping for a little bit (28). In GGE, a poor couple, vegetable farmers, put their pennies together to get one goose and thus some eggs to eat. Too much greed always leads to great loss (47). I ask: is there some such thing as just enough greed? A great illustration here (45) shows the goose's misgiving as she overhears the couple talking about getting all the eggs at once. The Hungry Fox and the Shepherds has a long build-up to the fox's discovery of lunches in the tree hollow, where the shepherds have stored them. The moral is surprisingly simple: Excess is bad (63). The Ungrateful Traveller is better known, I believe, in terms of a plane tree used by travellers for shade on a hot day. The conflict of this fable goes on between the two travellers, one of whom finds the tree useless, while the other is grateful for its shade. Then the tree gets into the conversation. In the second volume, titled Moral Stories, Jackal Learns a Lesson pairs the jackal with the tiger. This story is new to me. Tiger tries to keep jackal from harm, but jackal misconstrues him into an enemy. The Glass of Milk is given by a woman to a male teen-ager; he repays it years later as doctor to the now elderly sick woman. The woman's bill reads One glass of milk, now paid in full. This story provides the book's cover. William thinks that a stranger sitting next to him on a bench is eating up his cookies. The truth is that he has been eating the stranger's cookies! The last story seems silly to me. The head of a family discovers thieves in his house in the night and goes to a fortune-teller rather than to the police! This story on 69 has through where it needs thought.This is a hardbound book (hard cover)Second printin
Author response: Multiple short windows of calcium-dependent protein kinase 4 activity coordinate distinct cell cycle events during Plasmodium gametogenesis
No full textMalaria transmission relies on the production of gametes following ingestion by a mosquito. Here, we show that Ca2+-dependent protein kinase 4 controls three processes essential to progress from a single haploid microgametocyte to the release of eight flagellated microgametes in Plasmodium berghei. A myristoylated isoform is activated by Ca2+ to initiate a first genome replication within twenty seconds of activation. This role is mediated by a protein of the SAPS-domain family involved in S-phase entry. At the same time, CDPK4 is required for the assembly of the subsequent mitotic spindle and to phosphorylate a microtubule-associated protein important for mitotic spindle formation. Finally, a non-myristoylated isoform is essential to complete cytokinesis by activating motility of the male flagellum. This role has been linked to phosphorylation of an uncharacterised flagellar protein. Altogether, this study reveals how a kinase integrates and transduces multiple signals to control key cell-cycle transitions during Plasmodium gametogenesis.</jats:p

Hydrocarbon Seeded ABS - Nitrous Hybrid Engine Development: Experimental Validation of an Analytical Design Tool
No full textAfter the breakup of the Stratos III vehicle, inertial roll coupling was pinpointed to be the root cause. In order to battle the problem a propulsive roll control system was suggested to keep the roll rate under acceptable bounds. A restartable hybrid rocket engine using nitrous oxide and ABS plastic was proposed. 27 tests have been performed of which 10 were hot fires that had successful ignition. Analysis of this data yielded some boundaries of ignitability, given insights in promoting restartability and showed a low ignition delay of 100ms at a consistent stable ignition input power. Two tests featured helical ports showcasing control of the grain burn profile. In addition, a preliminary design tool was made and validated using the data of the hot fires. Modelled values for the feed system pressures and thrust output have been proven to be within ±10% of the experimental data.Aerospace Engineerin
