Vaccination is a preventive measure against influenza that does not require placing restrictions on social activities. However, since the stockpile of vaccine that can be prepared before the arrival of an emerging pandemic strain is generally quite limited, one has to select priority target groups to which the first stockpile is distributed. In this paper, we study a simulation-based priority t...

Most military radio systems exhibit relatively high bit error rates up to 10”3and possibly even higher. Many of these are located in the battlefield and are mobile, leading to temporary outages due to terrain blocking of signals. In battlefield situations, information delivery is critical and the highest priority and needs to be able to get through the relatively low bandwidth high error rate r...

OBJECTIVES The diamond model considers two dimensions of criteria, i.e., the magnitudes of rates and the trends in rates, in order to prioritize different health issues for health policy decision-making. We aimed in this study to use the diamond model to prioritize 30 causes of death (COD) by considering both the level of and inequality in mortality for the setting of policy goals in Taiwan. ...

We study photonic packet switching architecture that enables high node throughput and provides priority services. While an ultra-high-speed address-lookup capability can be realized in the optical domain for a photonic packet switch, the optical buffer must be managed in the electrical domain. In this paper, we propose a photonic buffer architecture that can support prioritized buffer managemen...

This paper presents the A ected Set Priority Ceiling Protocols (ASPCP) for concurrency control in real-time object-oriented systems. These protocols are based on a combination of semantic locking and priority ceiling techniques. This paper shows that the ASPCP protocols provide higher potential concurrency for object-oriented systems than existing Priority Ceiling protocols, while still boundin...

In this paper, we investigate a simplified head-of-the-line with priority jumps (HOL-PJ) scheduling discipline. Therefore, we consider a discrete-time single-server queueing system with two priority queues of infinite capacity and with a newly introduced HOL-PJ priority scheme. We derive expressions for the probability generating function of the system contents and the packet delay. Some perfor...

Advances in low-power electronics design and wireless communication have enabled the development of low cost, low power micro-sensor nodes. These sensor nodes are capable of sensing, processing and forwarding which have many applications such as underwater networks. In underwater wireless sensor networks (UWSNs) applications, sensors which are placed in underwater environments and predicted ena...

countries around the world are experiencing an ever-increasing need to make choices in investments in health and healthcare. this makes it incumbent upon them to have formal processes in place to optimize the legitimacy of eventual decisions. there is now growing experience among countries of the implementation of stakeholder participation, and a developing convergence of methods to support dec...

We obtain an essentially optimal tradeoff between the amortized cost of the three basic priority queue operations insert, delete and find-min in the comparison model. More specifically, we show that A(find-min) = Ω ( n (2 + )A(insert)+A(delete) )
