Author Identification in Malayalam using n-grams
No full textAuthor identification is the problem of identifying the author of an anonymous text or text whose authorship is in doubt from a given set of authors. The works by different authors are strongly distinguished by quantifiable features of the text. This paper deals with the attempts made on identifying the most likely author of a text in Malayalam from a list of authors. Malayalam is a Dravidian language with agglutinative nature and not much successful tools have been developed to extract syntactic & semantic features of texts in this language. We have done a detailed study on the various stylometric features that can be used to form an authors profile and have found that the frequencies of word collocations can be used to clearly distinguish an author in a highly inflectious language such as Malayalam. In our work we try to extract the word level and character level features present in the text for characterizing the style of an author. Our first step was towards creating a profile for each of the candidate authors whose texts were available with us, first from word n-gram frequencies and then by using variable length character n-gram frequencies. Profiles of the set of authors under consideration thus formed, was then compared with the features extracted from anonymous text, to suggest the most likely author.Cochin University Of Science And Technolog
Space logistics network optimization with embedded propulsion technology selection
No full textEstablishing long-term human presence beyond low Earth-orbit will require cooperative use of emerging technologies, such as low-thrust solar electric propulsion, along with existing space exploration technologies. Trajectory analysis plays a key role in deciding the costs of using different propulsion technologies. Traditional trajectory design methods are usually confined to analyzing individual missions using high-thrust or low-thrust propulsion options --- these techniques also do not usually consider the architectural aspects of the in-space network. On the other hand, determination of network architecture and mission sequence often relies on the expertise of mission designers. Thus, formulating and optimizing the problem as a multi-mission campaign can guide top-level decisions through rigorous mathematical modeling.
However, designing a multi-mission campaign with both propulsion options is generally computationally challenging due to the coupling of logistics network design and space transportation costs. Specifically, conventional space logistics planning methods are unable to account for the use of low-thrust vehicles for transportation due to the inherent nonlinear nature of associated costs. The aim of this work is to develop ways of handling low-thrust trajectory models within space logistics frameworks, so that propulsion technology trade-offs can be conducted internally.
This work develops two new frameworks for optimizing the combined use of low-thrust and high-thrust propulsion options within campaign-level space logistics planning tools. The first framework uses a chromosomal representation of network arc parameters to drive a multiobjective genetic algorithm that explores the tradespace. The second framework combines the generalized multicommodity network flow model with novel event-based time steps for dynamic space logistics optimization in the presence of nonlinear flight times associated with low-thrust transportation.
These methodologies are applied to the case study of Apollo-style crew missions to the lunar surface supported by in-space refueling via predeployed tanks delivered by cargo tugs. Although the costs for high-thrust trajectories are a part of the inputs to the formulation, the costs for low-thrust trajectories are determined internally because of their dependence on the thrust-to--mass ratio. For an efficient evaluation of low-energy, low-thrust transfers in the Earth–moon system, an approximation method is implemented based on a Lyapunov feedback control law called Q-law, and dynamical systems theory. This preliminary trajectory design technique is validated against literature sources and is then used to closely estimate the costs associated with cargo deliveries using low-thrust tugs.
Numerical results from the new space logistics frameworks reveal campaign profiles where high-thrust and low-thrust propulsion options can be used cooperatively to achieve substantial improvement over the baseline no-refuel cases. These results also present multiple options that involve in-space propellant storage and transfer, deep-space rendezvous, and solar electric propulsion tugs for cargo delivery. By trading mission costs with campaign duration, these methods help quantify the impact of low-thrust solar electric propulsion in logistics supply planning.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-12-01The student, Bindu Jagannatha, accepted the attached license on 2018-12-06 at 10:43.The student, Bindu Jagannatha, submitted this Dissertation for approval on 2018-12-06 at 10:57.This Dissertation was approved for publication on 2018-12-06 at 14:43.DSpace SAF Submission Ingestion Package generated from Vireo submission #13237 on 2019-02-07 at 14:23:01Made available in DSpace on 2019-02-07T20:44:25Z (GMT).

No full textSimulation based Analysis of Transformerless Photovoltaic Inverter Topologies for Reactive Power handling Capability
No full textThis study investigates the reactive power generation capability of the existing transformerless Photovoltaic Inverter Topologies (PVIT) with their conventional switching strategies. The topologies such as H5, families of H6 (H6, H6-I, H6-II, H6-III and H6-IV), HERIC, and clamped topologies (optimized H5, passive clamped H6 and HBZVR) have been selected for analysis. Matlab/Simulink simulation platform is employed for the analysis of PVIT. It has been observed that transformer-less PVIT with their conventional switching strategies are not suitable for reactive power injection. These topologies are generating highly distorted current at zero crossings during the reactive power flow. The improved switching strategies are needed to make these topologies suitable for the reactive power applications without any modification in the structure of the inverter.Accepted author manuscriptPhotovoltaic Materials and DevicesIntelligent Electrical Power Grid

Identifying Lane Changes Automatically using the GPS Sensor of Portable Devices
No full textAutomatic lane change identification can be used in warning systems that alert the driver when drifting off-lane, or in lane-specific navigation systems. Furthermore, they may help road authorities plan better road network design and infrastructure. Though lane-departure warning systems are already commercially available, these systems rely on on-board vehicle sensors. The availability of such systems can be increased if it became available to owners of smartphones or navigation devices. In this thesis, I propose and test several methods that rely solely on GPS data originating from portable devices (two smartphones, a GPS-equipped GoPro Max, and a USB GPS receiver), recorded during test rides on a Dutch highway (42.8 km) with a total of 64 lane changes. The methods rely on observing changes in the lateral offset between the GPS trajectories and the road geometry. The resulting identification accuracy of the best performing algorithm was achieved using the GoPro Max with an overall F1 score (harmonic mean of precision and recall) of 0.9 on the validation data using the signal of filtered projected lateral distance. It is concluded that GPS-equipped portable devices could be a suitable choice for identifying lane changes, provided there is improvement in the quality of GPS receiver chips with higher data collection frequency such as the ones used in GoPro Max.Mechanical Engineerin
