The PCN working group of the IETF discusses the use of pre-congestion notification (PCN) to implement flow admission control. Packet meters and markers are used on all network links and packet markings are recorded as congestion level estimates (CLEs) the egress nodes. The working group currently discusses the pros and cons of possible marking algorithms that play a major role in this new archi...

Scent-marking is widespread among mammals and has been observed in many felid species. Although the behaviour is well-described, little is known about its function in wild felid populations. We investigated patterns of scent-marking and its role in intra- and intersexual communication among resident and non-resident Eurasian lynx Lynx lynx by observing interactions among wild lynx at natural ma...

Assessment is an essential part of the learning process. It is important for educators to provide detailed and reliable evaluations to students so that they can be better prepared for future studies and the workplace. Marking and providing formative feedback can be time-consuming and prone to errors especially when detailed analyses of students’ problem-solving steps are considered. A computer-...

In this paper we explored factors that affect how children learning German understand which participant is the agent and which the patient in simple causative sentences (i.e. who does what to whom). Most languages, including German, have multiple cues to mark these roles. In two comprehension experiments we examined whether German children are able to use the grammatical cues of word order and ...

Laser marking is an important branch of the laser information processing technology. The existing laser marking machine based on PC and WINDOWS operating system, are large and inconvenient to move. Still, it cannot work outdoors or in other harsh environments. In order to compensate for the above mentioned disadvantages, this paper proposed an embedded laser marking controller based on ARM and ...
