We discuss empirical comparison of analytical methods for model selection. Currently, there is no consensus on the best method for finite-sample estimation problems, even for the simple case of linear estimators. This article presents empirical comparisons between classical statistical methods - Akaike information criterion (AIC) and Bayesian information criterion (BIC) - and the structural ris...

We explore the problem of discovering multiple missing values in a semi-structured database. For this task, we formally develop Structured Relevance Model (SRM) built on one hypothetical generative model for semi-structured records. SRM is based on the idea that plausible values for a given field could be inferred from the context provided by the other fields in the record. Small-scale experime...

This paper presents a rotor position estimation technique for a 6/4 switched reluctance machine based on Adaptive Neuro fuzzy Inference System (ANFIS). This technique is applied for modelling the nonlinear rotor position of SRM using the magnetization characteristics of the machine. ANFIS has a strong nonlinear approximation ability which could be used for nonlinear modelling and its real time ...

Family research aims to explore family processes, but is often limited to the examination of unidirectional processes. As the behavior of 1 person has consequences that go beyond that individual, family functioning should be investigated in its full complexity. The social relations model (SRM; Kenny & La Voie, 1984) is a conceptual and analytical model that can disentangle family data from a ro...

This paper describes the design and modeling procedure of a novel 5-phase segment type switched reluctance motor (ST-SRM) under simultaneous two-phase (bipolar) excitation of windings. The rotor cores of ST-SRM are embedded in an aluminum block as well as to improve the performance characteristics. The magnetic circuit of the produced ST-SRM is constructed so that the magnetic flux paths are sh...

soil salinization is a process in which the accumulation of soluble salts in soil profile can affect soil physical and chemical properties, such as osmotic pressure, permeability and hydraulic conductivity. these, in turn, can seriously impair or completely stop the growth of plants. in this study, four theoretical models for predicting soil leaching contains including series of reservoirs  mod...

This paper describes a stochastic dynamic programming based approach to solve Sensor Resource Management (SRM) problems such as occur in tracking multiple targets with electronically scanned, multi-mode radar. Specifically, it formulates the SRM problem as a stochastic scheduling problem and develops approximate solutions based on the Gittins index rule. Novel results include a hybrid state sto...

In this thesis, we conduct an extensive case study on formally modeling, analyzing, and designing retransmission-based reliable multicast protocols. We first present an abstract model of the communication service that several reliable multicast protocols [12, 13, 32–34] strive to provide. This model precisely specifies i) what it means to be a member of the reliable multicast group, ii) which p...

Switched reluctance motor (SRM) has many specific advantages and has being gradually used in many kinds of applications. However, because it’s inherently multivariable, strong coupling and highly nonlinear, there are lots of difficulties to build its model. In this paper, the basic operating principle of SRM are briefly introduced firstly, and then numerical and analytical modeling methods are ...
