Performance Evaluation of WW and WD Concurrency Control Algorithms for Database Management, via Modeling by Colored Petri Net [PDF]

open access: yesمجله مدل سازی در مهندسی, 2017
Any concurrent transaction should be taken in database could lead to conflict. The conflict occurs due to incorrect values for the data which lead to interference in executed transaction which has been taken. The concurrency control algorithms, to insure

Controlled Owicki-Gries Concurrency: Reasoning about the Preemptible eChronos Embedded Operating System [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
We introduce a controlled concurrency framework, derived from the Owicki-Gries method, for describing a hardware interface in detail sufficient to support the modelling and verification of small, embedded operating systems (OS's) whose run-time ...

The Canonical Amoebot Model: Algorithms and Concurrency Control [PDF]

open access: yes, 2021
The amoebot model abstracts active programmable matter as a collection of simple computational elements called amoebots that interact locally to collectively achieve tasks of coordination and movement. Since its introduction at SPAA 2014, a growing body of literature has adapted its assumptions for a variety of problems; however, without a standardized

The Logical Timestamp Skew Anomaly in Event-Replicated Transaction Schedulers

open access: yesIEEE Access, 2021
To sidestep reasoning about the complex effects of concurrent execution, many system designers have conveniently embraced strict serializability on the strength of its claims, support from commercial and open-source database communities and ubiquitous ...

Longitudinal predictors of weapon involvement in middle adolescence: Evidence from the UK Millennium Cohort Study

open access: yesAggressive Behavior, Volume 49, Issue 1, Page 5-14, January 2023., 2023
Abstract This study uses longitudinal data from the UK Millennium Cohort Study (N = 13,277) to examine the childhood and early adolescence factors that predict weapon involvement in middle adolescence, which in this study is exemplified by having carried or used a weapon.

Evaluation of an EPID in vivo monitoring system using local and external independent audit measurements

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The aim of this work was to evaluate the SunCHECK PerFRACTION, the software for in vivo monitoring using EPID images. Materials/Methods First, the PerFRACTION ability to detect errors was investigated simulating two situations: (1) variation of LINAC output and (2) variation of the phantom thickness.

CRIL: A Concurrent Reversible Intermediate Language [PDF]

open access: yesEPTCS 387, 2023, pp. 149-167, 2023
We present a reversible intermediate language with concurrency for translating a high-level concurrent programming language to another lower-level concurrent programming language, keeping reversibility. Intermediate languages are commonly used in compiling a source program to an object code program closer to the machine code, where an intermediate ...
