Batched network coding is a variation of random linear which has low computational and storage costs. In order to adapt fluctuations in the number erasures individual batches, it not optimal recode transmit same packets for all batches. Different distributed optimization models, are called adaptive recoding schemes, were formulated this purpose. The key component these problems expected value r...

Scalable group rekeying is one of the important problems that needs to be addressed in order to support secure multicast communications for large and dynamic groups. One of the challenging issues that arises in scalable group rekeying is the problem of delivering the updated keys to the members of the group in a reliable and timely manner. In this paper, we present a new scalable and reliable k...

Signature-based malware detection will always be a step behind as novel malware cannot be detected. On the other hand, machine learning-based methods are capable of detecting novel malware but classification is frequently done in an offline or batched manner and is often associated with time overheads that make it impractical. We propose an approach that bridges this gap. This approach makes us...

Queueing theory offers a large variety of techniques that can be used in performance modelling of computer systems and data communication networks. The diversity of assumptions causes that the numerical results, obtained for the same system but by means of different techniques, can often be numerically very different. The project is aimed at finding common denominators for numerical results obt...

Linear Programs (LPs) appear in a large number of applications and offloading them to the GPU is viable to gain performance. Existing work on offloading and solving an LP on GPU suggests that performance is gained from large sized LPs (typically 500 constraints, 500 variables and above). In order to gain performance from GPU for applications involving small to medium sized LPs, we propose batch...

background: the poor permeability of the plasma and nuclear membranes to dna plasmids are two major barriers for the development of these therapeutic molecules. therefore, success in gene therapy approaches depends on the development of efficient and safe non-viral delivery systems. objectives: the aim of this study was to investigate the in vitro delivery of plasmid dna encoding hpv16 e7 gene ...

In this paper, we propose a new transaction processing system for RESTful Web services; we describe a system architecture and algorithms. Contrary to other approaches, Web services do not require any changes to be used with our system. The system is transparent to non-transactional clients. We achieve that by introducing an overlay network of mediators and proxy servers, and restricting transac...

We report on a real-time application supporting fast, realistic real-time rendering of asteroid datasets, as well as collision detection and response between the asteroid and prototype robotic surface exploration vehicles. The system organizes the asteroid surface into a two-level multiresolution structure, which embeds a fine-grained perpatch spatial index within a coarse-grained patch-based s...
