摘要:
Methods, devices, and systems for controlling a scanning tunneling microscope system are provided. In some embodiments, the methods, devices, and systems of the present disclosure utilize a control system included in or added to a scanning tunneling microscope (STM) to receive data characterizing a tunneling current between a tip of the scanning tunneling microscope system and a sample, to estimate, in real-time, a work function associated with the scanning tunneling microscope system, and to adjust, by a control system, a position of the tip based on an estimated work function. Associated systems are described herein.

This invention relates to a method and system for determining the composition of an unknown sample. The present invention is directed to a method of calibrating an x-ray spectrometer that does not require measuring all possible elements under the operating conditions used to measure the unknown sample to be analyzed. According to a preferred embodiment, the local instrument can be calibrated from an x-ray spectrum of a single elemental standard. The instrument will have a stored library containing high quality spectra for all elements being analyzed. The analysis of the single element is compared to the library spectra for that element to define a transformation that is used to create a calibrated spectra library that includes a calibrated spectrum for each spectrum in the original library. The spectra generated by the local instrument can be compared to the calibrated library spectra to determine the elements in an unknown mineral.
摘要:
A method and system for spectrum data analysis. The method comprises the steps of collecting a spectrum of an unknown material; providing a set of data templates; calculating weighting factors for the element data templates to minimize error in approximating the spectrum; removing one or more of the templates having negative weights in approximating the spectrum; and re-calculating an approximation of the spectrum with said one or more templates removed. Embodiments of the invention are suitable for analyzing noisy spectra having relatively few data points.

Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes, particularly for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, by improving the water-fastness of the active agent to the plant or seed, by increasing soil penetration of the active agent to reach the plant roots or under soil parts, or by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.

A system and method for configuring a portal, comprising providing a first user interface operable to define and/or manage the portal; providing a second user interface operable to define and/or manage personalization of the portal; and wherein the portal can include at least one of the following portal resources: a desktop, a book, a page, a portlet, a shell, a look and feel, and a layout.
摘要:
A road vehicle steering system which is adapted to use measurements and estimates characterising the motion of and forces acting on the vehicle and the steering system such as to derive an estimate of steering system disturbance force and to then use the latter estimate to establish a torque demand for the vehicle electronic power steering (EPS) which substantially compensates for this disturbance force.

In embodiments, a system and method for submitting information to a lifecycle in a virtual content repository (VCR) is provided that includes defining the lifecycle wherein the definition includes a plurality states and one or more transitions to interconnect and impose an order on the plurality of states, providing to a first process access to the lifecycle wherein the first process can cause the information to transition from a first state of the plurality of states to a second state of the plurality of states according to a first transition of the one or more transitions, wherein the information is accessible through a logical namespace that encompasses the VCR, and wherein the information can include at least one of: content and schema information.
摘要:
In an exemplary method, a print server receives a request from a host for instructions regarding how to process graphics commands corresponding to a print job. In response, the print server determines whether raster image processing of the graphics commands is more efficiently performed by a raster image processing unit on the host or by one or more other raster image processing units. If the print server determines that the raster image processing is more efficiently performed by the host's raster image processing unit, the print server instructs the host to rasterize the graphics commands. If the print server determines that the raster image processing is more efficiently performed by the one or more other raster image processing units, the print server instructs the host to render the graphics commands into page description language data.
