Machine Learning-Powered Course Allocation

Proceedings of the 25th ACM Conference on Economics and Computation
We study the course allocation problem, where universities assign course schedules to students. The current state-of-the-art mechanism, Course Match, has one major shortcoming: students make significant mistakes when reporting their preferences, which negatively affects welfare and fairness.

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

Advanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

A combinatorial approximation algorithm for CDMA downlink rate allocation [PDF]

, 2004
This paper presents a combinatorial algorithm for downlink rate allocation in Code Division Multiple Access (CDMA) mobile networks. By discretizing the coverage area into small segments, the transmit power requirements are characterized via a matrix ...

Fully Bio‐Based Gelatin Organohydrogels via Enzymatic Crosslinking for Sustainable Soft Strain and Temperature Sensing

Advanced Functional Materials, EarlyView.
Enzymatically crosslinked gelatin‐based organohydrogels, fabricated through a fully bio‐based and scalable process, exhibit exceptional strain and temperature sensing capabilities with minimal interference from environmental humidity. These transparent, stretchable, and ionically conductive materials operate without synthetic fillers or dopants.

Optimal power allocation for DL NOMA systems

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
Non-orthogonal multiple access (NOMA) is an important candidate for 5G radio access technology. In NOMA transmitter, different users' signals are superposed on the same radio resource with different power allocation factors. The receiver removes other users' signals from the received signal before decoding its own signal.

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

Advanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

Power Allocation for Cache-Aided Small-Cell Networks With Limited Backhaul

IEEE Access, 2017
Cache-aided small-cell network is becoming an effective method to improve the transmission rate and reduce the backhaul load. Due to the limited capacity of backhaul, less power should be allocated to users whose requested contents do not exist in the ...

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

Advanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

Multiobjective Optimization Model for Wind Power Allocation

Mathematical Problems in Engineering, 2017
There is an increasing need for the injection to the grid of renewable energy; therefore, to evaluate the optimal location of new renewable generation is an important task. The primary purpose of this work is to develop a multiobjective optimization model that permits finding multiple trade‐off solutions for the location of new wind power resources. It
