  • Publication number: 20160157220
    Abstract: Cluster-based optimization of antenna tilts in a wireless network and other related aspects are presented herein. A screening component can receive information indicating wireless conditions of respective wireless access points of a geographical region, select, based on a performance criterion, an access point of the respective wireless access points, and group the access point and an other access point of the respective wireless access points into a representation of a cluster of access points. Further, an optimization component can derive antenna tilt values for respective access points of the cluster of the access points in response to a simulation of an application of the antenna tilt values to the respective access points. Furthermore, an implementation component can direct the antenna tilt values to respective components of the respective access points.

  • Patent number: 9354234
    Abstract: The present invention relates to a novel coumarin derivative, to a method for preparing the same, and a multi-fluorescent substance that includes a plurality of the coumarin derivatives and is able to emit light using an LED light source. A novel coumarin derivative multi-fluorescent substance according to the present invention has an optimal emission wavelength band of 512 nm to 590 nm and thereby is effective in improving a signal intensity and stability since light emission using an LED light source is possible. In addition, higher fluorescence reactivity is exhibited compared to coumarin fluorescent substances known in the related arts since one molecule has a plurality of fluorescent substances, and the problem of the coumarin fluorescent substance possibly binding to a binding site of the antigen of the antibody is solved since fluorescence detection is possible even when a minimum number of fluorescent substance molecules bind to an antibody.

  • Publication number: 20150044770
    Abstract: The present invention relates to a method for selective cell attachment/detachment, cell patternization and cell harvesting by means of near infrared rays. More particularly, conducting polymers or metal oxides having exothermic characteristics upon irradiation of near infrared light is used as a cell culture scaffold, thus selectively attaching/detaching cells without an enzyme treatment. The scaffold has an effect of promoting proliferation or differentiation of stem cells, and therefore, can be used as a stem cell culture scaffold. The scaffold enables cell attachment/detachment without temporal or spatial restrictions, thus enabling cell patternization.

  • Publication number: 20140162682
    Abstract: Systems and methods for overshooting cell device detection for application to self optimizing network algorithms are disclosed herein. The system ranks neighbor relationships between first, second, and third cell devices in a cellular network, based on handover statistics directly received from the cellular network. The system thereafter identifies one of the second cell device or the third cell device as an outlier neighbor cell device based on a ranking of the neighbor relationships and identifies, as a function of an azimuth direction and a distance between respective cell devices of a group of screened cell devices, an overshooting cell device that propagates a transmitted radio frequency signal causing interference to a cell device included in the group of screened cell devices.
