De Facto Security Standards: Operators at Risk
Hotel security standards required by law tell only half the story: Actual court decisions are equally valid when it comes time to enforce the rule of “reasonable care.” Our survey of hotel owners and operators collected data about court-mandated security standards and we discuss which of those standards hoteliers consider important and which are controversial
Increasing survey response rates: Practical instructions from the total-design method
Abstract Increasing surveys' response rates can substantially enhance the accuracy of interpreted findings. Here are proven, ready-to-use suggestions for encouraging survey returns while keeping costs in line with traditional survey techniques.
A traffic scheduling framework in broadband wireless access systems
In this paper, we present a traffic scheduling framework for allocating the upstream channel bandwidth in broadband wireless access systems, where both voice and data applications are supported. Our traffic scheduling framework is aimed at supporting diverse QoS requirements and obtaining high utilization of the upstream bandwidth. It prioritizes traffic streams according to different classes of service, and provides fair access of bandwidth to the users. The presented framework consists of three algorithms: a calibration algorithm for the jittered constant bit rate (CBR) traffic, a scheduling algorithm for the jittered CBR traffic, and a scheduling algorithm for the unspecified bit rate traffic. The proposed algorithms are feasible when either the asynchronous transfer mode or multi-protocol label switching protocol is deployed at the network edge. Simulation results are presented to demonstrate the effectiveness of our algorithms in achieving high bandwidth utilization and the good traffic performance in terms of both cell loss ratio and mean queuing delay.
