We describe several algorithms and public servers that were developed to analyze and predict various features of protein structures. These servers provide information about the covalent state of cysteine (CYSREDOX), as well as about residues involved in non-covalent cross links that play an important role in the structural stability of proteins (SCIDE and SCPRED). We also discuss methods and se...

Today, location-based applications and services such as friend finders and geo-social networks are very popular. However, storing private position information on thirdparty location servers leads to privacy problems. In our previous work, we proposed a position sharing approach for secure management of positions on non-trusted servers [1, 2], which distributes position shares of limited precisi...

Web server performance has steadily improved since the inception of the World Wide Web. We observe performance gains of two orders of magnitude between the original process-based Web servers and today’s threaded Web servers. Commercial and academic Web servers achieved much of these gains using new or improved event-notification mechanisms and techniques to eliminate reading and copying data, b...

We consider a two-node multiclass queueing network with two types of jobs moving through two servers in opposite directions, and there is infinite supply of work of both types. We assume exponential processing times and preemptive resume service. We identify a family of policies which keep both servers busy at all times and keep the queues between the servers positive recurrent. We analyze two ...

We study two problems of private matrix multiplication, over a distributed computing system consisting master node, and multiple servers that collectively store family public matrices using Maximum-Distance-Separable (MDS) codes. In the first problem Private Secure Matrix Multiplication (PSMM) from colluding servers, intends to compute product its confidential A with target stored on without re...
