A user who does not have a quantum computer but wants to perform computations may delegate his computation cloud server. In order that the delegation works, it must be assured no evil server can obtain any important information on computation. The blind protocol was proposed as way for protect from unauthorized actions of Among protocols thus far, with two servers sharing entanglement, while re...

In this paper, the state diagrams and steady-state balance equations for two kinds of open queuing network models are presented. The first model comprises a network of single queues with single servers, while the second model comprises multiple servers for single queues. State diagrams are drawn for (2,3) queuing networks with (i) single servers and (ii) multiple servers. Steady-state balance e...

We consider simple parallel queueing models in which a proportion of arriving customers are flexible, i.e. they are willing to receive service at any one of some subset of the parallel servers. For the case of two parallel servers, we show that as the servers become fully utilized, the maximum improvement in mean waiting times is achieved for arbitrarily small levels of flexibility. The insight...

In many industrial situations, machines are subjected to random breakdowns. In this paper, we consider the asynchronous vacation policy for the multi-server machine repair problem with server breakdown and two types of spares. According to this policy, when a certain number of servers become idle at a service completion instant, the servers will take an asynchronous vacation of random length to...

Many organisations enforce policies on the length and formation of passwords to encourage selection of strong passwords and protect their multi-user systems. For Two-Server Password Authenticated Key Exchange (2PAKE) and Two-Server Password Authenticated Secret Sharing (2PASS) protocols, where the password chosen by the client is secretly shared between the two servers, the initial remote regis...

Here, we describe two freely available web servers for molecular docking. The PatchDock method performs structure prediction of protein-protein and protein-small molecule complexes. The SymmDock method predicts the structure of a homomultimer with cyclic symmetry given the structure of the monomeric unit. The inputs to the servers are either protein PDB codes or uploaded protein structures. The...

Two server password-based authentication protocols (Two-Server PAKE), where two servers co-operate to authenticate a client on the basis of Password only and if one server is compromised due to Insider Attack or Distributed Denial Of Service Attack (DDOS). In Asymmetric two-server PAKE protocol runs in series and only the front-end server and the client need to establish a secret session key. I...

We consider an M/M/R queueing system with finite capacity N, where customers have two arrival modes under steady-state conditions. It is assumed that each arrival mode is serviced by one or more servers, and that the two arrival modes have equal probabilities of receiving service. Arrival times of the customers and service times of the severs follow an exponential distribution. A cost model is ...

This project involves comparing two relational database servers using sections of the AS3AP industry standard benchmark. The two servers tested were Oracle 8.0.3, developed by the Oracle Corporation and MySQL 3.22.14b-gamma, developed by T.c.X DataKonsultAB. The servers were both installed on the same Intel-based hardware platform running the Red Hat Linux 5.2 operating system (kernel 2.0.36). ...
