We present the Time Lag/Delay Reconstructor (TLDR), an algorithm for reconstructing velocity delay maps in Maximum A Posteriori framework reverberation mapping. Reverberation mapping is a tomographical method studying kinematics and geometry of broad-line region active galactic nuclei at high spatial resolution. Leveraging modern image reconstruction techniques, including Total Variation Compre...

introduction: over the past two decades, the incidence of cesarean section in most countries has increased.developmental delay occurs when children do not reach their developmental milestones at the expected time. the main causes of developmental delay are often unknown. investigation of the prevalence of developmental delay and its effective factors in children from 4 to 12 months old in pakda...

The challenges posed by global climate change are motivating the investigation of strategies that can reduce the life cycle greenhouse gas (GHG) emissions of products and processes. While new construction materials and technologies have received significant attention, there has been a limited emphasis on understanding how construction processes can be best managed to control GHG emissions. Unex...

This master thesis presents a preliminary investigation into the impact of TCP’s advertised receive buffer size and timer granularity on TCP performance over an erroneous link in a low earth orbit (LEO) satellite environment. Conducted simulations include over 200 different combinations of TCP flavor, advertised receive buffer size, timer granularity, and bit error rates. Results show that TCP ...

This paper, according to the process of capital return, establishes a differential dynamics model investment with two time delays. When both delays are zero, it is proved that positively invariant, uniformly bounded, and globally asymptotically stable by using comparison principle Bendixson–Dulac theorem. at least one delay not Hopf bifurcation theorem, conditions local asymptotic stability exi...

This project evaluate the performance of improved power delay profile estimation in Multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) systems under linear minimum mean square error(LMMSE) channel. The distortions caused by null subcarriers and a short range of samples for PDP estimation is also considered. The proposed technique effectively estimates the dist...

We investigate the impact of First-In-First-Out (FIFO) flow aggregation on delay performance of a Differentiated Services (DiffServ) network in the context of Expedited Forwarding (EF). Specifically, the focus is on investigating the impact of FIFO aggregation on edge-toedge delay performance. Motivated by the IST Moby Dick project, the investigation is mainly conducted through simulation. On t...

This project proposes delay efficient architecture for shift registers by using pulsed latches instead of flip flops. By using latches instead of flip-flops the major factors area and power can be reduced. By considering the necessary delays in pulses for latches the timing problem latches can be reduced. For obtaining these delays counter has to incremented by 1. The proposed kogge stone adder...

The multiprocessor task scheduling problem is an NP-complete problem that is difficult to solve via traditional methods. Recent investigations have used evolutionary computation to evolve optimized schedules, but have failed to address the effects of communications delay on the schedules. As such, the schedules produced are often less than optimal. The goal of this project was to extend previou...
