Achieving full transmit diversity for PPM constellations with any number of antennas via double position and symbol permutations

Abou-Rjeily, Chadi; Baba, Z, (2016-02-16)

We present a general technique for constructing minimal-delay rate-1 Space-Time (ST) block codes for Pulse Position Modulations (PPM) with an arbitrary number of transmit antennas. We show that the novel idea of time-domain ...
Active laminar mixing induced by surface disturbance

Akle, Barbar; Williams, Alicia; Vlachos, Pavlos (ASME, 2018-01-22)

Traditionally, passive mixers and chaotic advection have played a key role in the field of microfluidics by stretching and folding the fluid. Some examples of these passive mixing techniques include channels with riblets ...
Activity-level space scheduling

Zouein, Pierrette P.; Tommelein, Iris D. (2018-10-15)

Activity-level space scheduling involves allocating site space over time to static and dynamic construction resources such as robots. The resulting coarse layouts pertaining to activity-related time intervals serve to ...
Acute toxicity of boron, titanium dioxide, and aluminum nanoparticles to Daphnia magna and Vibrio fischeri

Strigul, Nikolay; Vaccari, Liana; Galdun, Catherine; Wazne, Mahmoud; Liu, Xuyang; Christodoulatos, Christos; Jasinkiewiczc, Kristin (2016-02-29)

The acute toxicity of four different nanosized particulate materials (titanium dioxide, boron nanoparticles, and two types of aluminum nanoparticles (ALEX and L-ALEX)) were evaluated using two tests: the Microtox toxicity ...
Adaptive Energy Management Strategy for a Hybrid Vehicle Using Energetic Macroscopic Representation

Mansour, C.; Salloum, N.; Francis, S.; Baroud, W. (IEEE, 2020-09-29)

The Energetic Macroscopic Representation is used in this paper to model a pre-transmission parallel hybrid electric vehicle and its control and energy management system. Since optimizing energy management onboard is among ...
Adaptive false discovery rate for wavelet denoising of pavement continuous deflection measurements

Katicha, Samer W.; Loulizi, Amara; El Khoury, John; Flintsch, Gerardo (2019-09-18)

The traffic speed deflectometer (TSD) is a device used to evaluate the pavement’s structural condition. Measurements obtained from the TSD are affected by noise, which can make it hard to interpret test results. The main ...
Adjoint sensitivity analysis of nonlinear distortion in radio frequency circuits

Tannir, Dani; Khazaka, Roni (2020-07-17)

Measuring the effects of nonlinear intermodulation distortion is one of the main requirements in the design of radio frequency circuits. The third-order intercept point (IP3) is one of the main figures of merit that is ...
Adjoint sensitivity analysis of nonlinear distortion in RF circuits

Tannir, Dani; Khazaka, Roni (IEEE, 2020-07-23)

Recently, an efficient moments based method for computing the third order intercept point of RF circuits was proposed. The moments based approach did not however provide sensitivity information. In this paper we propose a ...
Advances in fluid mechanics XII

Hernandez, S.; Skerget, L.; Ravnik, J. (WIT Press, 2021-11-04)

Previous Scale-Resolving Simulation studies of flow over urban-like obstacles uses Large Eddy Simulation and course grids to reduce computational cost. However, the coarser the mesh the more reliance on the subgrid scale ...
An agent-based framework for simulating contractors’ safety behavior

Awwad, Rita; Abi Shdid, Caeser; Tayeh, Ralph (ASCE, 2017-05-09)

A contractor’s attitude towards construction safety, and the subsequently implemented safety program, are complex phenomena that are affected by a wide array of factors. These factors can range from government policy and ...
Agent-based model for simulating construction safety climate in a market environment

Awwad, Rita; Abi Shdid, Caesar; Tayeh, Ralph (2017-02-22)

A strong construction safety climate is sought after by governments, owners, and insurance providers. When making safety policy changes, legislative bodies and construction stakeholders alike try to successfully predict ...
