Abstract We present a comparison of woody browse availability and white-tailed deer (Odocoileus virginianus) use among clearcut interiors, skidder trail edges, and mature forest and an evaluation of the relative importance of aboitic factors in predicting browsing pressure within regenerating clearcuts in the central Appalachians of West Virginia. We sampled 810 1-m2 plots in or adjacent to nine regenerating clearcuts (8–19 ha) during the summer of 2001. Availability and use of woody browse did not differ between clearcut interior and skidder trail plots for any species observed. Plots in the

CV Bagus Agung Mandiri Sejatera (CV BAMS), one of the CV (Commanditaire Vennotschaap) Wi-Fi service providers in the Blitar area, currently serves 3 regions and serves 800 customers. In the Wi-Fi monthly bill payment process, there are problems in the process of finding customer IDs and the number of payment recap documents that are input manually. Therefore, a Wi-Fi payment information system using a QR Code is needed. This system aims to manage payment data by scanning QR Code on customer cards and using them as data sources to generate reports and recaps to owners in the form of PDF files.

Abstract The integration of 5G mm-wave and Wi-Fi frequency bands becomes significant for upcoming 5G wireless applications for providing a large frequency ratio. This work presents a frequency reconfigurable hexagonal metamaterial resonator (HMR) antenna for Wi-Fi and a 5G mm-wave frequency band. A PIN diode is utilized to link up a microstrip patch antenna (MPA) with HMR to achieve integration of the Wi-Fi frequency band. The resonant frequency of the proposed antenna is 5 GHz (Wi-Fi) and 27.87 GHz with peak gain 2.33 dB and 7.12 dB, respectively. The operating bandwidth of the proposed anten

Abstract:

As cameras and Wi-Fi access points are widely deployed in public places, new mobile applications and services can be developed by connecting live video analytics to the mobile Wi-Fi-enabled devices of the relevant users. To achieve this, a critical challenge is to identify the person who carries a device in the video with the mobile device's network ID, e.g., MAC address. To address this issue, we propose RFCam, a system for human identification with a fusion of Wi-Fi and camera data. RFCam uses a multi-antenna Wi-Fi radio to collect CSI of Wi-Fi packets sent by mobile devices, and a camera to

Abstract:

In order to solve the problem of pedestrian positioning in the indoor environment, this paper proposes a high-precision indoor pedestrian positioning system (HPIPS) based on smart phones. First of all, in view of the non-line-of-sight and multipath problems faced by the radio-signal-based indoor positioning technology, a method of using deep convolutional neural networks to learn the nonlinear mapping relationship between indoor spatial position and Wi-Fi RTT (round-trip time) ranging information is proposed. When constructing the training dataset, a fingerprint grayscale image construction me

Background: Hymenoptera venom anaphylaxis (HVA) is reported in up to 3% of stings and accounts for approximately 40 US deaths annually. HVA patients require immediate availability of epinephrine and Allergist referrals for consideration of venom immunotherapy. Data regarding epinephrine autoinjector prescriptions, Allergist referral rates, and potential racial disparities are limited. Objective: The primary objective was to determine if there were statistically significant differences in epinephrine autoinjector prescriptions and Allergist referrals between white and African American patients.

Hence, VPN tunnel can be represented as a TCP/IP connection. TCP/IP protocol stacks are oriented to support high-speed int

Anti-Müllerian hormone (AMH) is a small peptide hormone that has been associated with ovarian follicular reserve in humans and in some animal species including bovine. Profiles of AMH, as well as the relationship between serum AMH to oocyte number and in vivo embryo production, were evaluated in Holstein cows. AMH levels were determined in 15 unstimulated cows at monthly intervals for 4 months and in 394 male and 399 female developing Holstein animals from birth to adulthood. Also, AMH was measured in 41 heifers at the time of ovum pick-up (OPU) and 125 heifers at the time of embryo flushing.
