No full textAbstract: Accurate reconstruction of phylogenetic trees often involves solving hard optimisation problems, particularly the Maximum Parsimony (MP) and Maximum Likelihood (ML) problems. Various heuristics yield good results for these problems within reasonable time only on small datasets. This is a major impediment for large-scale phylogeny reconstruction. Roshan et al. introduced Rec-I-DCM3, an efficient and accurate meta-method for solving the MP problem on large datasets of up to 14,000 taxa. We improve the performance of Rec-I-DCM3 via parallelisation. The experiments demonstrate that our parallel method, PRec-I-DCM3, achieves significant improvements, both in speed and accuracy, over its sequential counterpart
Rapid coordinate system creation and mapping using Crickets
No full textThesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2004.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (leaves 55-56).In this thesis, I describe a system that lays the foundation for context-aware applications. This system allows a user to set up a reference coordinate system in a room, using three Cricket listeners attached to a wooden frame. The system then assigns coordinates to Cricket beacons, which are placed on the ceiling. Finally, by using the frame in conjunction with a laser range finder, the user can generate a map of the room in the reference coordinate system, complete with features including doors, walls, and windows. This thesis also describes necessary changes we implemented that made the Cricket positioning system much more accurate.by Roshan Bantwal Baliga.M.Eng
Challenges in Virtual Testing of Autonomous Vehicles
No full textThe worldwide development of Autonomous Vehicles (AVs) has also encouraged the use of software simulators for virtual testing of AVs. However, the effectiveness of the AV simulators is constrained by numerous challenges, such as their computational cost and lack of fidelity in specific areas. In this paper, we describe the modality of virtual testing and its benefits for AV development and validation. Moreover, we summarize and provide an overview of the state-of-the-art AV simulators, their limitations, and the current directions toward improvement.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Signal Processing System
Combinatory actions of CP29 phosphorylation by STN7 and stability regulate leaf age-dependent disassembly of photosynthetic complexes
No full text© 2020, The Author(s). A predominant physiological change that occurs during leaf senescence is a decrease in photosynthetic
efciency. An optimal organization of photosynthesis complexes in plant leaves is critical for efcient
photosynthesis. However, molecular mechanisms for regulating photosynthesis complexes during leaf
senescence remain largely unknown. Here we tracked photosynthesis complexes alterations during
leaf senescence in Arabidopsis thaliana. Grana stack is signifcantly thickened and photosynthesis
complexes were disassembled in senescing leaves. Defects in STN7 and CP29 led to an altered
chloroplast ultrastructure and a malformation of photosynthesis complex organization in stroma
lamella. Both CP29 phosphorylation by STN7 and CP29 fragmentation are highly associated with the
photosynthesis complex disassembly. In turn, CP29 functions as a molecular glue to facilitate protein
complex formation leading phosphorylation cascade and to maintain photosynthetic efciency during
leaf senescence. These data suggest a novel molecular mechanism to modulate leaf senescence via
CP29 phosphorylation and fragmentation, serving as an efcient strategy to control photosynthesis
complexes.11Nsciescopu
CoPEM: Cooperative Perception Error Models for Autonomous Driving
No full textIn this paper, we introduce the notion of Cooperative Perception Error Models (coPEMs) towards achieving an effective and efficient integration of V2X solutions within a virtual test environment. We focus our analysis on the occlusion problem in the (onboard) perception of Autonomous Vehicles (AV), which can manifest as misdetection errors on the occluded objects. Cooperative perception (CP) solutions based on Vehicle-to-Everything (V2X) communications aim to avoid such issues by cooperatively leveraging additional points of view for the world around the AV. This approach usually requires many sensors, mainly cameras and LiDARs, to be deployed simultaneously in the environment either as part of the road infrastructure or on other traffic vehicles. However, implementing a large number of sensor models in a virtual simulation pipeline is often prohibitively computationally expensive. Therefore, in this paper, we rely on extending Perception Error Models (PEMs) to efficiently implement such cooperative perception solutions along with the errors and uncertainties associated with them. We demonstrate the approach by comparing the safety achievable by an AV challenged with a traffic scenario where occlusion is the primary cause of a potential collision.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Signal Processing System
A research about the real author of Marzbanname Tabari
No full textMarzbanname is the name of a book which includes narrations and allegories and marzban wrote it in old tabari language. Mohammad Ibn Ghazi maltivi in 598 A.H. and sadoddin varavini in the first half of seventh century translated it to farsi. Onsorolma' ali keykavos, the writer of Ghaboosname and Ibn Esfandyar, the writer of tarikhe – Tabarestam believe that marzban ibne Rostam ibne shervin (the 13th king of Bavandiya kiyosiye chain) in the real writer of marzbanname. But sa'daddin varavini believes that marzban ibne shervin (shervin = 5th king of Bavandiye kiyosiye) is the writer of it. Reza Gholi khane – hedayat knows marzban- Ibn – e – rostam as the outher of marzban-e-Deylami in some other books. Among the contemporaries, shefer knows marzban-ibn –e-rostam-ibn –e- sorkhab – ibn – e- Gharan as the author of marzban name, but Allame Ghazvini rejects this hierarchical order. Allame Dehkhoda, Esmaeil mahjouri, Ardeshir Barzegar and Hossein Eslami believe that marzban- ibn- e- Rostam wrote maezban name. mohammad Roshan reject all and say that there is no book named marzban name tabari.This article believes that varavini's speech about the writer of marzbanname is correct but not of onsorolma' ali keykavoos and ibne Esfandyar's speech
