The main contribution of this work is to propose energy-eecient randomized initialization protocols for ad-hoc radio networks (ARN, for short). First, we show that if the number n of stations is known beforehand, the single-channel ARN can be initialized by a protocol that terminates, with high probability, in O(n) time slots with no station being awake for more than O(log n) time slots. We the...

This paper defines principles for organizing semantic relations represented by slots in frame-structured knowledge bases. We consider not only the ways in which slots are used for reasoning about a given domain but also the features of the representation language of the knowledge-based system in which the slots reside. We find that the organization of slots may be based on the knowledge-level s...

Recently standardized wireless systems have multiple Time-Slots in a radio frame, but existing MUMIMO schedulers are not utilizing multiple Time-Slots efficiently. In this paper we propose a sub-optimal user grouping algorithm utilizing multiple Time-Slots efficiently. The proposed algorithm disperses highly-correlated users in different Time-Slots to prevent severe degradation of spatial multi...

In this paper, we propose a TDMA slot assignment protocol to improve the channel utilization, which controls the excessive increase of unassigned slots by changing the frame length dynamically. Our proposed protocol assigns one of the unassigned slots to a node which joins the network. If there is no unassigned slots available, our proposed protocol generates unassigned slots by depriving one o...

An analysis of laminar natural convection in inclined slots subjected to patterned heating has been performed. The imposed takes a simple form characterized by single Fourier mode combined with uniform heating. It is shown that periodic applied at the lower plate produces no net flow when slot either horizontal or vertical, but upward generated tilted. Periodic upper downward situation. additio...

In this paper a method of ordering slots of verb schemata related by diathesis alternations is presented. Such schemata are grouped together and represent a single meaning of a verb. The schema dominating in a group is found and its slots are numbered w.r.t. their obliqueness hierarchy. These numbers are propagated to other schemata accordingly to alternations linking slots of schemata related ...

Permeable interlocking concrete pavements (PICP) are specifically designed to remove sediment and other pollutants from stormwater runoff. Over time, this can lead to clogging of the PICP system. Previous research has shown that much of the clogging occurs on the bedding aggregate directly below the paving joints, while the remainder of the aggregate is unaffected. This paper describes a proof ...
