Effects of Response-Independent Food Delivery During Timeout on Timeout Punishment
<p>Timeout is a signaled, response-dependent, and time limited period in which the prevailing schedule of reinforcement is suspended. Timeouts are one of the most frequently used punishment procedures in clinical and parental practices. Even though timeout is a common punishment practice, recent …

Fixed -interval timeout from avoidance with humans
… effects of an immediately consumable reinforcer, timeout from avoidance. In Experiment 1, adult human subjects responded on a concurrent schedule with avoidance of point-loss in one component, and timeout from avoidance in the other. Timeout was scheduled on FI with inter-reinforcement intervals …

Limits of sensitivity to delayed timeout from avoidance
… conceptualizing session reduction as a delayed timeout from avoidance, the present study investigated the limits of molar control while minimizing several methodological limitations inherent in such procedures. Six times during each session, a two-link chain schedule was superimposed on a …

Frequency of Reinforcement as a Determinant of Timeout Effectiveness
… integral part of the punishment procedure termed timeout from positive reinforcement. The influence that different reinforcement requencies have on the effectiveness of a one minute timeout procedure was investigated. Procedure: Four profoundly retarded adolescent males served as subjects in a …

The Suppression of Disruptive Classroom Behavior with Three Durations of Timeout
The problem. Previous research on timeout duration has suggested that short duration timeouts would not be effective when presented following a history of longer duration timeout. This study analyzed the suppressive effects of short duration timeout both prior to and following a longer duration and …

Negative Reinforcement by Timeout from Avoidance: The Roles of Discriminative Cues, Shock-Frequency Reduction, and Response-Effort Reduction
Timeout from avoidance is an effective reinforcer, but the reason is not firmly established. Rats responded on concurrent schedules of avoidance and timeout. Pressing the right lever postponed shocks according to a schedule with a response-shock interval of 30 s and a shock-shock interval of 5 s, …

A Needs Assessment Regarding a Fire Risk Assessment Checklist In the Operating Room
… checklist to the already established surgical timeout prior to every procedure being performed. Setting: This project took place at a Level 1 trauma hospital in the greater Phoenix, Arizona metro area. The study included (N=16) participants, who were the members of the surgical team at this …

Improving TCP performance over heterogeneous networks : The investigation and design of End to End techniques for improving TCP performance for transmission errors over heterogeneous data networks.
… update mechanism, retransmission mechanism and timeout mechanism. All of these mechanisms are part of the TCP congestion control mechanism. We propose changes to each of these mechanisms in order to allow TCP to cope with transmission errors. We propose a new TCP congestion window action (CWA) …

Armadillo
… are introduced into the model. TCP may timeout and quit as a response to these events and therefore yield a suboptimal performance. This work introduces Armadillo, a protocol to hide intermittent connectivity from TCP applications on mobile hosts to increase performance. In contrast to …

Cross-layer protocol interactions in heterogeneous data networks
(cont.) TCP timeout backoff and MAC layer retransmissions, are studied in detail. The results show that the system performance is a balance of idle slots and collisions at the MAC layer, and a tradeoff between packet loss probability and round trip time at the transport layer. Finally, we consider …

Assessing time away and teachers' perceptions of its effectiveness on girls with behavioral problems
… TA involves three phases (Albrecht, 1992): timeout—after several unsuccessful attempts by the teacher to resolve conflicts, the offending student is sent to the TA room and placed in a 10-min timeout ("cool down") period; redirection—the student then participates briefly in an academic …

Computer Virus Spread Containment Using Feedback Control.
… Also because of delaying, many connections timeout and get dropped, reducing the spread. PID controller is implemented to decide the number of connections going to safe or suspected queue. Multiple controllers can be implemented to control the parameters like delay and timeout. Control …

An Energy Aware and Secure MAC Protocol for Tackling Denial of Sleep Attacks in Wireless Sensor Networks
… Media Access Control ( protocols Sensor MAC, Timeout MAC andTunableMAC under different network sizes and measuring different parameters such as the Received Signal Strength RSSI) and Link Quality Indicator ( Transmit power, throughput and energy efficiency Duty cycling happens to be one of the …

New techniques to lower the tail latency in stream processing systems
… we present three mechanisms: (1) adaptive timeout coupled with selective replay to catch straggler tuples; (2) shared queues among different tasks of the same operator to reduce overall queueing delay; (3) latency feedback-based load balancing, intended to mitigate heterogenous scenarios. …

The effects of five discrete variables on human performance in a telephone information system
… dependent measures: database structure by input timeout, database structure by wallet guide, input timeout by wallet guide, and speech rate by wallet guide. Twelve subjective ratings were also analyzed. The results show at least one of the 12 subjective ratings was significantly affected by …

Routing tradeoffs in dynamic peer-to-peer networks
… the need for both low lookup hop-count and low timeout probability. Accordion employs a unique design for managing routing tables.

Providing application-aware reliability through OS/hypervisor-level techniques
… the watchdog is not reset within a predefined timeout interval. The detection latency might be significant because the timeout interval for resetting the watchdog timer is usually a matter of seconds to reduce false alarms. The approach in this thesis enables low-latency OS-hang detection …
