The ground thermal properties and the heat-transfer efficiency of the borehole heat exchanger (BHE) system are key parameters for designing ground-coupled systems. Proper design of such systems requires good knowledge of these parameters, providing an efficient and economic operation. For this purpose a test procedure known as Thermal Response Test (TRT) was developed in 1996 at the Oklahoma St...

Introduction: Oscillation based test (OBT) method [1] has been applied to testing different types of analogue circuits [2-5]. In this approach, the circuit is transformed into an oscillator during the test mode and the frequency of oscillation is measured and compared to the reference value obtained on a known-good circuit operating in the same conditions. Circuit modification for the purpose o...

Thermal response test (TRT) is an established method to determine design parameters for borehole heat exchanger (BHE) systems; borehole thermal resistance and effective ground thermal conductivity. Most commonly, these tests are performed with heat injection, using the same assumed power level as the planned BHE system. For a thorough description of TRT and current activities around the world, ...

BACKGROUND The goal of this work is to develop a digital version of a standard cognitive assessment, the Trail Making Test (TMT), and assess its utility. OBJECTIVE This paper introduces a novel digital version of the TMT and introduces a machine learning based approach to assess its capabilities. METHODS Using digital Trail Making Test (dTMT) data collected from (N = 54) older adult partici...

Previous experiments have shown that cats respond to noxious thermal pulse stimulation of the upper hind limb at an average latency of 2.3 sec. To determine if C fiber afferents could mediate this response, we recorded the response latency and threshold of single fibers of cat femoral cutaneous nerve to the same stimuli used in the behavioral experiments. Of 28 C fibers tested, 10 (36%) respond...

Electronic Knowledge Repository (EKR) is one of the most commonly deployed knowledge management technologies, yet its success is hindered by employees’ underutilization and further complicated when implemented in the multinational context. To address these challenges, we propose a research model by conceptualizing employees’ knowledge seeking via EKR as a survival-centric behavior, identifying ...
