This study evaluated a community-based and social marketing healthy corner store program (FIT store) to improve the affordability and availability of healthy foods in low-income, urban, and ethnically diverse neighborhoods in Michigan. The Nutrition Environment Measures Survey in Stores data were analyzed for the FIT (N = 4) stores. Two cross-sectional surveys were conducted among the FIT store customers before (N = 401) and after (N = 318) the intervention. Three FIT stores improved their total Nutrition Environment Measures Survey in Stores availability score from before to after the intervention. A significantly higher level of FIT awareness and monthly bean and nut consumption was reported in the postintervention. Copyright ©ippincott Williams &Wilkins.

This paper proposes a new switched control design method for some classes of linear time-invariant systems with polytopic uncertainties. This method uses a quadratic Lyapunov function to design the feedback controller gains based on linear matrix inequalities (LMIs). The controller gain is chosen by a switching law that returns the smallest value of the time derivative of the Lyapunov function. The proposed methodology offers less conservative alternative than the well-known controller for uncertain systems with only one state feedback gain. The control design of a magnetic levitator illustrates the procedure. © 2013 Wallysonn A. de Souza et al. Source

In this paper, Defected Ground Structure (DGS) Microstrip patch antenna using complementary metamaterial (C-MTM) is studied and analyzed. The aim of the study in such type of antenna is to achieve multiband application which is the demand of current technology. The rectangular patch antenna has been designed and simulated using CST Microwave Studio 2013. The simulations results are presented for a patch antenna with and without the Complementary metamaterial. The simulation results shows that antenna with complementary metamaterial etched in the ground plane is resonating at three different frequency; 1.88 GHz, 2.02 GHz, and 2.43GHz with minimal return loss of-11.85dB,-15.64dB and-11.84dB respectively. Whereas, the antenna without C.MTM is resonating at 2.4 GHz. The size reduction is achieved. © 2015 IEEE. Source

This paper presents a new driving scheme utilizing an in-pixel metal-insulator-semiconductor (MIS) photosensor for luminance control of active-matrix organic light-emitting diode (AMOLED) pixel. The proposed 3-TFT circuit is controlled by an external driver performing the signal readout, processing, and programming operations according to a luminance adjusting algorithm. To maintain the fabrication simplicity, the embedded MIS photosensor shares the same layer stack with pixel TFTs. Performance characteristics of the MIS structure with a nc-Si:Hα-Si:H bilayer absorber were measured and analyzed to prove the concept. The observed transient dark current is associated with charge trapping at the insulator-semiconductor interface that can be largely eliminated by adjusting the bias voltage during the refresh cycle. Other factors limiting the dynamic range and external quantum efficiency are also determined and verified using a small-signal model of the device. Experimental results demonstrate the feasibility of the MIS photosensor for the discussed driving scheme. © 2005-2012 IEEE. Source

Over the past decade, automation has become a trend in every dimension of the technology namely industrial, automobile, aerospace, defence and information technology. But the automation in different fields demands different platforms. Therefore to achieve uniformity and congruity, this paper provides a UNIVERSAL WIRELESS GATEWAY FOR AUTOMATION to support the automation of all the above mentioned fields. SCADA (Supervisory control and Data Acquisition) and Cloud technologies are the two most rapidly evolving technologies in the last few years. The integration of automation with other technologies always escalates its resourcefulness. So an embedded system is proposed and built to endorse the collaboration of SCADA and Cloud technologies to achieve automation through supervision and control of a system or a set of systems from a remote place over different networks. A low power operating system design techniques is presented to avail the services of the input/output devices consuming less power. This paper also provides a platform to supervise and monitor a huge system and avail the cloud services using minimum resources and cost of implementation. © 2015 IEEE. Source
