A peer-to-peer system can be de ned as an overlay network built by a set of nodes on top of a physical network infrastructure and its operating protocols, such as the Internet. In a peer-to-peer network, each node maintains a limited number of connections with other nodes, called peers, and the graph of peer connections constitutes the overlay's topology. One of the most fundamental properties ...

Source traac streams as well as aggre-gated traac ows often exhibit long-range-dependent (LRD) properties. In this paper, we model each traac stream component through the multiplicative multi-fractal counting process traac model. We prove that the superposition of a nite number of multiplicative multifractal traac streams results in another multi-fractal stream. This property makes the multifra...

Trust management for peers in P2P network is very much important due to its open and anonymous nature. In this paper, we propose a reputation based trust management scheme for partially decentralized peer-to-peer file sharing systems. Reputation data is stored at the super node level. We calculate the reputation value for each file by using fuzzy logic inferences, which can better handle uncert...

In this paper a technique is presented which improves the noise immunity of TSPC circuit. This technique is compared with other existing techniques. Analysis is carried out both for super and sub-threshold regions of operation. Investigations consider different performance criteria viz. n ooise immunity curve, power consumption, delay, average noise threshold energy (ANTE), PANTE and DANTE. The...

schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

Temperatures are effective indicators of the health of many machines such as the wind turbine gearboxes, bearings, engines, etc. This paper presents a novel wireless temperature sensor node powered by a thermal harvester for monitoring the status of gearboxes. A thermoelectric generator module (TEG) is optimized to harvest the electrical power from a heat source such as the gearbox undergoing s...

With limited coverage of wireless networks and frequent roaming of mobile users, providing a seamless communication service poses a technical challenge. In our previous research, we presented a supernode system architecture that employs the delay-tolerant network (DTN) concept to provide seamless communications for roaming users over interconnected heterogeneous wireless networks. Mobile ad hoc...

Cluster deduplication has become a widely deployed technology in data protection services for Big Data to satisfy the requirements of service level agreement (SLA). However, it remains a great challenge for cluster deduplication to strike a sensible tradeoff between the conflicting goals of scalable deduplication throughput and high duplicate elimination ratio in cluster systems with low-end in...

Structural health monitoring (SHM) is the science of assessing the integrity of structures such as buildings, bridges and aerospace structures. SHM systems strive to detect and locate damage in structures as early as possible. Today most automated SHM system has been suggested that wireless sensing can potentially bring about a dramatic reduction in cost by doing away with the cabling cost. Sel...

The case of a simultaneous robotic radical nephroureterectomy, genital tract and paravaginal nerve-sparing robotic radical cystectomy, super-extended pelvic lymph node dissection and intracorporeal Studer pouch construction on a 57-year old female patient with muscle invasive bladder and distal ureteral tumors, along with a hydroureteronephrotic nonfunctioning right kidney is presented. The ent...
