A computational scheme for fitting smoothing spline ANOVA models to large data sets with a (near) tensor product design is proposed. Such data sets are common in spatial-temporal analyses. The proposed scheme uses the backfitting algorithm to take advantage of the tensor product design to save both computational memory and time. Several ways to further speed up the backfitting algorithm, such a...

Bonferroni’s Adjustment (also known as Dunn’s procedure). This procedure is simple to use and can be applied in a wide variety of situations where alpha correction is needed (and is perhaps most appropriate for situations other than the post hoc situation discussed here). To obtain a corrected critical value the desired alpha is divided by the number of comparisons or tests performed and that v...

Choi et al. recently proposed an efficient RFID authentication protocol for a ubiquitous computing environment, OHLCAP(OneWay Hash based Low-Cost Authentication Protocol). However, this paper reveals that the protocol has several security weaknesses : 1) traceability based on the leakage of counter information, 2) vulnerability to an impersonation attack by maliciously updating a random number,...

The paper examines the two basic Bandwidth Constraint models for MPLS networks, called Maximum Allocation Model and Russian Dolls Model, from the point of view of Quality of Service guarantees and introduces the results of performance evaluation of these models in a simulation scenario. We evaluated the influence of the Bandwidth Constraint models on the most important transmission parameters s...

Some of the existing time memory tradeoff attacks (TMTO) on specific systems can be reinterpreted as methods for inverting general oneway functions. We apply these methods back to specific systems in ways not considered before. This provides the following startling results. No streamcipher can provide security equal to its key length; some important blockcipher modes of operations are vulnerabl...

We introduce the notion of stateless multihead two-way (respectively, oneway) NFAs and stateless multicounter systems and relate them to P systems and vector addition systems. In particular, we investigate the decidability of the emptiness and reachability problems for these stateless automata and show that the results are applicable to similar questions concerning certain variants of P systems...

background: job satisfaction is an emotional and positive feeling which results from job assessment or experiences. it is always considered as a problem in some organizations. despite the important role of nutrition therapy in patients care, dietitians’ job satisfaction is less taken into account. the aim of the present study was to determine the amount of job satisfaction among dietitians in f...

A new beam propagation method (BPM) is developed based on a direct approximation to the propagator using the [p/(p+1)] Padé approximant. It is simple to construct and has the desired damping effect for the evanescent modes. The method is applied to a tapered waveguide for TM polarized waves, using the oneway Helmholtz equation and its energy conserving improvement. Numerical results are compare...
