High precision relative GPS positioning is based on the very precise carrier phase measurements. In order to achieve high precision results within a short observation time span, the integer nature of the GPS double difference ambiguities has to be exploited. In this contribution we concentrate on the integer ambiguity estimation, which is one of the steps in the procedure for parameter estimati...

This paper is a survey of the theory and methods of photogrammetric bundle adjustment, aimed at potential implementors in the computer vision community. Bundle adjustment is the problem of refining a visual reconstruction to produce jointly optimal structure and viewing parameter estimates. Topics covered include: the choice of cost function and robustness; numerical optimization including spar...

This paper estimates some of the parameters of the Schwartz and Moon (2001)) model using cross-sectional data. Stochastic costs, future financing, capital expenditures and depreciation are taken into account. Some special conditions are also set: the speed of adjustment parameters are equal; the implied half-life of the sales growth process is linked to analyst forecasts; and the risk-adjustmen...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...

From the point of view of information processing the immune system is a highly parallel and distributed intelligent system which has learning, memory, and associative retrieval capabilities. In this paper we present two immunity-based hybrid learning approaches for function approximation (or regression) problems that involve adjusting the structure and parameters of spatially localized models (...

The geometrical rule of molecular packing parameters in a bolaamphiphile solution was tested with experimental results. By modifying the solution conditions to change the molecular packing parameters, the morphology of the aggregate was successfully manipulated in a single-chain bolaamphiphile, disodium phenyl-1,4-bis (oxyhexanoate) (i.e., C6PhC6Na2 solution). Micelle-vesicle-tube transformatio...

With the extensive spread of the Internet and mobile terminals, the Internet access from a mobile terminal becomes more important than ever before. In the Internet, Transmission Control Protocol (TCP) is used as a standard data transport protocol, however, it is well known that TCP performance degrades in wired-wireless network environments. This is because TCP is designed originally for wired ...

The theoretical model of emotion regulation and many empirical findings have suggested that children's emotion regulation may mediate the association between parents' emotion socialization and children's psychological adjustment. However, limited research has been conducted on moderators of these relations, despite the argument that the associations between parenting practices and children's ps...
