Homomorphic encryption schemes are an essential ingredient to design protocols where different users interact in order to obtain some information from the others, at the same time that each user keeps private some of his information. When the algebraic structure underlying these protocols is complicated, then standard homomorphic encryption schemes are not enough, because they do not allow to c...

In this paper we steer wheeled nonholonomic systems that can be represented in a so called chained form Su cient conditions for converting a multiple input system with nonholonomic velocity constraints into a multiple chain single generator chained form via state feedback and a coordinate transformation are presented along with sinusoidal and polynomial control algorithms to steer such systems ...

This paper presents a new scheme for scheduling and control synthesis in high-level circuit design. The scheduling algorithm tries to maximize the performance of a design under resource constraints by maximizing the utilization of resources and minimizing clock slack. It exploits the technique of bit-level chaining (BLC) to target high-speed design. It also exploits noninteger multicycling and ...

Scalability and availability are key features of parallel database systems. To realize scalability, many dynamic load-balancing methods with data placement and parallel index structures on sharednothing parallel infrastructure have been proposed. Data migration with range-partitioned placement using a parallel Btree is one solution. The combination of range partitioning and chained declustered ...

This paper attempts to address an important concept--prototypicality ---in cognitive studies on the categorization of the English tense system, and raises the grammatical and functional approaches to the tense system to the level of universal cognition. On the theoretical basis of prototype theory, this research addresses the prototype of category TENSE, its cognitive features, and the mechanis...

This paper investigates three MICE methods: Predictive Mean Matching (PMM), Quantile Regression-based Multiple Imputation (QR-basedMI) and Simple Random Sampling (SRSI) at imputation numbers 5, 15, 20 30 with 5% 20% missing values, to ascertain the one that produces imputed values best matches observed compare model fit based on AIC MSE. The results show that; QR-basedMI produced more didn’t ma...
