Beyond Local Optimality of Buffer and Splitter Insertion for AQFP Circuits
Giovanni De Micheli, Heinz Riener, Siang-Yun Lee
Adiabatic quantum-flux parametron (AQFP) is an energy-efficient superconducting technology. Buffer and splitter (B/S) cells must be inserted to an AQFP circuit to meet the technology-imposed constraints on path balancing and fanout branching. These cells a ...
ACM2022Deciding Robustness for Lower SQL Isolation Levels
While serializability always guarantees application correctness, lower isolation levels can be chosen to improve transaction throughput at the risk of introducing certain anomalies. A set of transactions is robust against a given isolation level if every p ...
ASSOC COMPUTING MACHINERY2022Resolving time conflicts in activity-based scheduling
Michel Bierlaire, Timothy Michael Hillel, Janody Pougala
In this paper, we present a novel activity-based scheduling model that combines a continuous optimisation framework for temporal scheduling decisions (i.e. activity timings and durations) with traditional discrete choice models for non-temporal choice dime ...
2021Resolving time conflicts in activity-based scheduling: A case study of Lausanne
Michel Bierlaire, Timothy Michael Hillel, Janody Pougala
In this paper, we present a novel activity-based scheduling model that combines a continuous optimisation framework for temporal scheduling decisions (i.e. activity timings and durations) with traditional discrete choice models for non-temporal choice dime ...
2021A dynamic scheduling tool and a methodology for creating digital twin of manufacturing systems for achieving Zero Defect Manufacturing
Foivos Psarommatis Giannakopoulos
Nowadays manufacturing environment is highly volatile and rapidly changing as the need of products is increasing exponentially, due to the fact that Product Life Cycle is shortened and therefore more products are required to be manufactured or remanufactur ...
EPFL2021A generic methodology and a digital twin for zero defect manufacturing (ZDM) performance mapping towards design for ZDM
Foivos Psarommatis Giannakopoulos
Over recent years, the manufacturing industry has seen constant growth and change. From one side, it has been affected by the fourth industrial revolution (Industry 4.0). From the other side, it has had to enhance its ability to meet higher customer expect ...
2021Plunge and rebound of a taxi market through COVID-19 lockdown: Lessons learned from Shenzhen, China
This paper traces the plunge and rebound of the taxi market in Shenzhen, China through the COVID-19 lockdown. A four-week taxi GPS trajectory data set is collected in the first quarter of 2020, which covers the period of lockdown and phased reopening in th ...
2021Exploring causalities between modal habits, activity scheduling, and multi-day locational practices.
Marc-Edouard Baptiste Grégoire Schultheiss
Despite raising awareness of sustainable behavior and considerable investments in the public transport network and active mobility infrastructure, car use remains the main practice for daily mobility in Switzerland. This work postulates that resistances to ...
2021A Reinforcement Learning Approach to Train Routing and Scheduling
Good train scheduling for a big network with many trains is very hard to achieve. As the trains are competing for the tracks with one another, the number of constraints grows rapidly. Trying to take advantage of emerging technologies in the areas of optimi ...
2020Task scheduling for highly concurrent analytical and transaction workloads
Anastasia Ailamaki, Iraklis Psaroudakis
Systems and method for a task scheduler with dynamic adjustment of concurrency levels and task granularity are disclosed for improved execution of highly concurrent analytical and transactional systems. The task scheduler can avoid both over commitment and ...
