This paper presents an adaptive resource control mechanism for multihop ad-hoc network systems, which avoids bottleneck problems caused by the node-fairness property of IEEE 802.11. In our proposal, the feedback information from the downstream bottleneck, derived from Request-To-Send (RTS) and Clear-To-Send (CTS) messages is utilized to control the Transmission Opportunity (TXOP) limit of the u...

active queue management (aqm) plays an important role in the internet congestion control. it tries to enhance congestion control, and to achieve tradeoff between bottleneck utilization and delay. random early detection (red) is the most popular active queue management algorithm that has been implemented in the in internet routers and is trying to supply low delay and low packet loss. red algori...

Object detection in aerial images is a critical and essential task the fields of geoscience remote sensing. Despite popularity computer vision methods detecting objects, these have been faced with significant limitations such as appearance occlusion variable object sizes. In this letter, we explore conventional neck networks by analyzing information bottlenecks. We propose an enhanced network t...

Identification of the second of two targets is impaired if it is presented less than about 500 ms after the first. Three models of this second-target deficit, known as attentional blink (AB), were compared: resource-depletion, bottleneck, and temporary loss of control (TLC). Five experiments, in which three sequential targets were inserted in a stream of distractors, showed that identification ...

This paper presents a heuristic for the dynamic vehicle scheduling problem with multiple resource capacity constraints. In the envisaged application, an automated transport system using Automated Guided Vehicles, bottleneck resources are (1) vehicles, (2) docks for loading/unloading, (3) vehicle parking places, and (4) load storage space. This problem is hard, because interrelated activities (l...

Bovine respiratory disease (BRD) is a major cause of illness and death in cattle; however, its global extent distribution remain unclear. As climate change continues to impact the environment, it important understand environmental factors contributing BRD’s emergence re-emergence. In this study, we used machine-learning models remotely sensed data at 2.5 min (21 km2) resolution layers estimate ...

The model of a single central bottleneck for human information processing is critically examined. Most evidence cited in support of the model has been observed within the overlapping tasks paradigm. It is shown here that most findings obtained within that paradigm and that were used to support the model are also consistent with a simple resource model. The most prominent findings are the millis...

Currently available nucleic acid testing (NAT)-based assays are complex and time-consuming, and they require expensive instrumentation and dedicated laboratory spaces for sample preparation as well as for amplification and detection of the nucleic acid target. Reagents required for these tests are also expensive and must be transported and stored refrigerated or frozen. These characteristics ha...
