A dynamic porous coordination network with a hydrophobic channel was assembled from stretchable 1D metallosalen polymer, which has the ability to recognize and, particularly, separate aromatic hydrocarbons from aliphatic mixtures with high selectivity.

This paper presents a novel teleoperation controller for a nonlinear master–slave robotic system with constant time delay in communication channel. The proposed controller enables the teleoperation system to compensate human and environmental disturbances, while achieving master and slave position coordination in both free motion and contact situation. The current work basically extends the pas...

Mobile ad-hoc networks (MANETs) are expected to provide certain levels of Quality of Service (QoS) under varying wireless channel capacity and noise constraints. These noisy and varying channel conditions make it difficult to provide reliable and efficient real-time communication in MANETs. In this thesis, we explore three techniques to enable better utilization of mobile ad hoc networks under ...

Dual channels have become popular strategies for manufacturers due to the development of innovative selling platforms. Examples in practice also show that the lack of relationship management, such as cooperation and sharing, may cause an unsustainable supply chain performance. However, previous studies on coordination of dual-channel supply chains always focus on the contribution to profits and...

Energy efficiency of a MAC protocol is one of the most important performance metrics, especially in mobile ad hoc networks, where the energy sources are limited. Two key factors in achieving energy efficiency for a MAC protocol are coordination among the nodes and schedule-based channel access. In order to achieve a sufficient level of coordination among the nodes, and hence to achieve energy e...

Within the wireless mesh network, a bottleneck problem arises as the number of concurrent traffic flows (NCTF) increases over a single common control channel, as it is for most conventional networks. To alleviate this problem, this paper proposes a two-stage coordination multi-radio multi-channel MAC (TSC-M2MAC) protocol that designates all available channels as both control channels and data c...

Cooperative advertising is a practice that a manufacturer pays retailers a portion of the local advertising cost in order to induce sales. Cooperative advertising plays a significant role in marketing programs of channel members. Nevertheless, most studies to date on cooperative advertising have assumed that the market demand is only influenced by advertising expenditures but not by retail pric...

To understand the mechanisms of Na(+)/Li(+) permeation at submicromolar Ca(2+) concentrations, Na(+)/Li(+) blocking at higher Ca(2+) concentrations (10(-6)-10(-4) M) and Ca(2+) permeation at millimolar Ca(2+) concentrations, we used our recently described L-type calcium channel model. For this purpose, we obtained potential of mean force (pmf) curves for the position change of one Na(+) and one...

Relationships have traditionally been studied between business actors. This paper brings the framework for analysis of business relationships to consumer markets. Internet bank relationships introduce a new communication channel for the bank customer. This paper explores coordination and understanding of internet bank service in relationships between banks and their customers. The paper also id...

Pilot contamination severely degrades the achievable rates in massive MIMO systems. To resolve the problem, many channel state information (CSI) and channel distribution information (CDI) methods were developed. This paper presents a CDI based pilot coordination method that leads to a considerable improvement in the achievable sum rate. It also shows that pilot assignment can drastically affect...
