Decentralized cryptocurrencies rely on participants to keep track of the state of the system in order to verify new transactions. As the number of users and transactions grows, this requirement places a significant burden on the users, as they need to download, verify, and store a large amount of data in order to participate. Vault is a new cryptocurrency designed to minimize these storage and ...

The vault particle, with a molecular weight of about 10 MDa, is the largest ribonucleoprotein that has been described. The X-ray structure of intact rat vault has been solved at a resolution of 3.5 Å [Tanaka et al. (2009), Science, 323, 384-388], showing an overall barrel-shaped architecture organized into two identical moieties, each consisting of 39 copies of the major vault protein (MVP). Th...

We investigate the security of a privacy enhancing technique for fingerprint authentication known as fuzzy fingerprint vault. This technique is based on the fuzzy vault of Jules and Sudan, a scheme that allows error tolerant authentication, while preserving the privacy of the reference data. We explore if and under what circumstances a secure fuzzy fingerprint vault can be implemented. We deriv...

According to the number of Internet in widely use and the development of the related application, the need of security system which can protect individual information has increased. Biometrics-based user authentication has several advantages over traditional password-based systems for standalone authentication applications. However, security of biometric data is particularly important as the co...

Nowadays, there is no precedent for building a high-speed railway in diatomite area. Due to the complex structure and poor mechanical properties of as well lack relevant engineering experience, more attention has been paid proper constitutive model tunnel layer using numerical calculation method, while traditional Elastoplastic most used yet. Therefore, relying on Feifengshan tunnel, through FL...

OBJECTIVE Our aim is to investigate sonographically detectable vault hematomas after vaginal hysterectomy and its relation to postoperative morbidity. METHODS We studied a group of 103 women who had undergone vaginal hysterectomy for benign causes apart from uterovaginal prolapse. Transabdominal ultrasound examinations were carried out 24 to 72 hours after surgery to assess the presence of va...

The paper presents a novel agile approach to large scale design of enterprise data warehouses based on a Data Vault model. An original, simple and direct algorithm is defined for the incremental design of physical Data Vault type enterprise data warehouses, using source data meta-model and rules, and used in developing a prototype case tool for Data Vault design. This approach solves primary re...

Biometric systems play an important role in authenticating the identity of an individual. Such authenticated systems are still prone to attacks and securing them is an important issue. To overcome this, biometric based authentication is blended with cryptography resulting in a framework called fuzzy vault which provides a high level of security. Fuzzy vault is a biometric cryptosystem used for ...

Abstract This research is stressed at time and space characteristics (centre of gravity movements) in female pole vault. There are involved 19 vault jumpers with sport performance 380 – 483 cm, divided on 2 different groups; higher lower level from the point performance. We found that parameters reached better results high phases hanging lifting. It coursed by transmission after take-off work p...

Underground engineering construction is facing increasingly complex geological conditions and challenges, such as surrounding rock deformation lining cracking, that seriously threaten the safety of tunnel operation. Aiming at these problems, a pipeline crossing jointed expansive mudstone strata was taken an example, disaster characteristics were analyzed through field investigation. The disaste...
