NEURAL NETWORKS by LIN LIU (Under the Direction of Takoi Hamrita) ABSTRACT To understand the relationships among ambient temperature (AT), relative humidity (RH) and broiler deep body temperature (DBT), controlled experiments were conducted for different RH (50 and 80%) and AT (31, 34 and 37C) combinations. The DBT measurements were collected by a radio biotelemetry system. Three types of Artif...
In this paper, an all-digital and low-power reference clock generator with cell-based design for biotelemetry applications is presented. The proposed clock generator employs a cascade-stage structure to achieve high resolution and wide range at the same time. Besides, based on the proposed Schmitt-trigger-based delay cell (STDC), hysteresis delay cell (HDC), and digitally controlled varactor (D...
Animal-borne video and environmental data collection systems (AVEDs) are an advanced form of biotelemetry that combines video with other sensors. As a proxy for physiological stress, we assessed fecal glucocorticoid metabolite (FGM) excretion in 7 white-tailed deer (Odocoileus virginianus) fitted with AVED dummy collars; 9 additional deer served as controls. We collected fecal samples over 3 2-...
In this paper, the design of micro-power CMOS ring VCO with minimum jitter intended for a concept of frequency synthesizer in biotelemetry systems is studied. A design procedure implemented in MATLAB is described for a circuit realization with TSMC 0.18μm CMOS technology. This conventional design methodology based on EKV3.0 model is clearly suited to the challenges of analog circuits design wit...
This article proposes an efficient and complete wireless power transfer (WPT) system (WPTS) for multipurpose biomedical implants. The WPTS is composed of a self-diplexing implantable antenna, rectifier, WPT transmitter (WPT Tx). proposed capable simultaneously transmitting recorded data recharging the batteries devices (so as to elongate implant life). Tx occupies dimensions 50 ×50 ×1.6 mm <sup...
Despite significant advances in the access control domain, requirements of new computational environments like web services still raise new challenges. Lack of appropriate method for specification of access control policies (ACPs), composition, verification and analysis of them have all made the access control in the composition of web services a complicated problem. In this paper, a new indepe...
In this paper, a miniaturized skin implantable biocompatible microstrip antenna is proposed for biotelemetry applications at 2.4–2.48 GHz. The volume of the 42.68 mm3 with dimensions 8.2 × 6.94 0.75 mm3. Rogers RO Duroid 3010 0.25 mm thickness used designing antenna. This material also as superstrate to cover from both sides provide safety patients. Further, specific absorption rate (SAR) analy...
ate its performance in relation to field biotelemetry. When attached to fishes in the wild, the DO transmitter may be exposed to temporally and spatially changing temperatures. This issue is emphasized by laboratory studies on Atlantic cod (Gadus morhua) demonstrating how this species may decrease the preferred temperature as a response to hypoxia (Petersen and Steffensen, 2003). Accordingly, t...
