In the P2P network, how to quickly and accurately positioning of resources is a key measure of the performance. Nowadays, distributed P2P system generally adopts DHT search method, DHT-based P2P network search algorithm of P2P is a hot topic. The paper introduces the background and current research status of the DHT. Then focused on the Pastry algorithm, Finally Pastry algorithm was analyzed an...

Although peer-to-peer overlays have been elaborately studied, they still have redundant overheads. Pastry and Chord use leaf sets to connect those nodes contiguous in numerical space, but these pointers have no contribution to efficient routing. In this paper we argue that if the mapping between a message key and its root node is determined in a smart way, leaf sets can be removed, largely decr...

Group-communication applications are a very promising opportunity for developing valuable MANET-based applications. However, real-world experimental studies are required to indicate the best solutions to implement them. We have implemented a real prototype in which alternative networking stacks can be used to support a distributed Whiteboard application. By means of experimental results we show...

BACKGROUND This study sought to identify occupations with high incidence of multiple myeloma and to investigate possible excess risk associated with occupational exposure to chemicals and sensitizing agents in Sweden. METHODS A historical cohort of 2,992,166 workers was followed up (1971--1989) through record linkage with the National Cancer and Death Registries. For each job category, age an...

OBJECTIVES High consumption of bakery products such as cream-filled pastries may cause serious health risks and food poisoning to humans. Therefore, investigation of the microbial and chemical qualities of bakery products containing cream is necessary. The purpose of the present study was to investigate the chemical qualities and microbial contaminations of cream-filled pastries collected from ...

After the spread of Covid-19 outbreak had an effect on world education, changes to learning system were directed online home study policy. This aims determine management competency achievement in Pastry course. research method uses a quantitative by comparing student outcomes during pandemic and before course at IKK FPP UNP department. The is basic practical that requires more direct lecturer g...

BACKGROUND Alongside flour, fat is the key ingredient of sponge cakes, including those with long shelf lives. It is an unstable food component, whose quality and nutritional safety depend on the composition and pres- ence of oxidation products. Consumption of fat oxidation products adversely affects the human body and contributes to the incidence of a number of medical conditions. Qualitative c...

In particular, we address the problem of each peer choosing the k best pointers to store in addition to its index pointers to minimize the average query lookup times. We focus on two popular P2P systems, namely Pastry and Chord: we exploit the inherent structure of these systems to develop efficient, scalable algorithms for optimally choosing the k additional pointers. Simulations with Chord an...
