Design of distributed network video recording system for coal mine
In view of phenomenon that traditional centralized network video recording system has insufficient video processing capacity of storage device and network congestion when videos involve multi-channel, large capacity and data concurrency, a distributed ...

Repairing Serializability Bugs in Distributed Database Programs via Automated Schema Refactoring [PDF]
Serializability is a well-understood concurrency control mechanism that eases reasoning about highly-concurrent database programs. Unfortunately, enforcing serializability has a high-performance cost, especially on geographically distributed database clusters.

Distributed transactions suffer from poor performance due to two major limiting factors. First, distributed transactions suffer from high latency because each of their accesses to remote data incurs a long network delay.

A new secure 2PL real-time concurrency control algorithm (ES2PL)
A secure concurrency control algorithms must be devoid of covert channels originating from data conflicts between transactions, in addition to ensuring database integrity.

Specifying Transaction Control to Serialize Concurrent Program Executions [PDF]
We define a programming language independent transaction controller and an operator which when applied to concurrent programs with shared locations turns their behavior with respect to some abstract termination criterion into a transactional behavior.

On the use of non-concurrent controls in platform trials: A scoping review [PDF]
Platform trials gained popularity during the last few years as they increase flexibility compared to multi-arm trials by allowing new experimental arms entering when the trial already started. Using a shared control group in platform trials increases the trial efficiency compared to separate trials.

Formal analysis of control and termination of distributed computation in weaker spaces
The control and termination detection of a distributed computation involving large-scale distributed database is difficult in the presence of concurrency, random network delays, and varying reliability of computing nodes. The formal modeling and analysis

LF+ in Coq for "fast and loose" reasoning
We develop the metatheory and the implementation of LF+, and discuss several applications. LF+ capitalizes on research work, carried out by the authors over more than a decade, on Logical Frameworks.

Conventional 802.11 carrier sense multiple access/collision avoidance (CSMA/CA) networks perform channel contention and data transmission serially over a whole channel. This leads to low throughput efficiency.

Distributed optimistic concurrency control with reduced rollback [PDF]
Concurrency control algorithms have traditionally been based on locking and timestamp ordering mechanisms. Recently optimistic schemes have been proposed. In this paper a distributed, multi-version, optimistic concurrency control scheme is described which is particularly advantageous in a query-dominant environment.
