IRMA is a reliable multicast architecture that guarantees reliable, sequenced, and loosely synchronized delivery of multicast streams. IRMA provides ACK-based reliability, hybrid local server-initiated and sender-initiated loss recovery, and support for end-to-end flow control and congestion control. Unlike most contemporary work, IRMA supports TCP as the reliable multicast transport protocol a...

We consider the problem of controlling a two-server Markovian queueing system with heterogeneous servers. The servers are differentiated by their service rates and reliability attributes (i.e., the slower server is perfectly reliable while the faster server is subject to random failures). The aim is to dynamically route customers at arrival, service completion, server failure, and server repair...

a single server queue with bernoulli vacation has been considered. in addition the admission to queue is based on a bernoulli process and the server gives two type of services. for this model the probability generating function for the number of customers in the queue at different server's state are obtained using supplementary variable technique. some performance measures are calculated. ...

The rapid growth of information enables a large increase in needs of recommendation. To satisfy this need, Collaborative Filtering and Social Filtering are adopted as solutions for personalized music recommendation. Contemporary recommender systems based on collaborative filtering and social filtering always suffer problems of unreliable item similarity, rating sparsity, lack of rating and un-r...

Consider a system of many components with constant failure rate and general repair rate. When all components are reliable and easily reparable, the reliability of the system can be evaluated from the probability q of failure before restoration. In [14], authors give an asymptotic approximation by monotone sequences. In the same framework, we propose, here, a bounding for q and apply it in the a...

Server-Aided Secret Computation(SASC) protocol enables the client(smart card) to borrow the computing power from the server(un trusted auxiliary device like ATM) without revealing the secret information of the client. The previous approach is to decompose the client's secret information into many pieces and to reveal some of them to the server. It signiicantly accelerates the secret computation...

The AKT signaling pathway has been identified as an important target for cancer therapy. Among small-molecule inhibitors of AKT that have shown tremendous potential in inhibiting cancer, MK-2206 is a highly potent, selective and orally active allosteric inhibitor. Promising preclinical anticancer results have led to entry of MK-2206 into Phase I/II clinical trials. Despite such importance, the ...

A portable electrocardiogram (ECG) monitoring system is essential for elderly and remote patients who are not able to visit the hospital regularly. The connects a patient his/her doctor through an Internet of Things (IoT) cloud server that provides all information needed diagnose heart diseases. Patients use ECG device collect upload regarding their current medical situation via Message Queue T...
