Electron accelerators from 500 keV to 10 MeV energy are employed for surface irradiation, food preservation, medical sterilization, cargo scanning and other industrial products. At EBC, a 10 MeV Linac has been indigenously developed and is operational for radiation processing. This is an on-axis coupled cavity standing wave type of RF linac operating with 50-70 keV electron gun having LaB6 cath...

An easy, one-step procedure is proposed for the synthesis of highly porous carbon nanosheets with an excellent performance as supercapacitor electrodes. The procedure is based on the carbonization of an organic salt, i.e., potassium citrate, at a temperature in the 750-900 °C range. In this way, carbon particles made up of interconnected carbon nanosheets with a thickness of <80 nm are obtained...

The aims of this study were to introduce a new laboratory microwave device developed for the modification of wood properties and to examine the effect of microwave radiation on moisture loss, surface temperature, and mechanical properties (the static modulus of elasticity MOE, and the modulus of rupture MOR) of Norway spruce (Picea abies). The device was developed for a continuous modification ...

A 2x2 mixed design experiment (N=52) was conducted to examine the effects of search method and task complexity on users’ information-seeking performance and affective experience in an e-commerce context. The former factor had two within-participants conditions: keyword (KW) vs. natural language (NL) search; the latter factor had two between-participants conditions: simple vs. complex tasks. The...

We consider the problem of designing an allocation rule or an “online learning algorithm” for a class of bandit problems in which the set of control actions available at each time t is a convex, compact subset of R. Upon choosing an action x at time t, the algorithm obtains a noisy value of the unknown and time-varying function ft evaluated at x. The “regret” of an algorithm is the gap between ...

OBJECTIVE Family caregivers often accompany patients to medical visits; however, it is unclear whether caregivers rate the quality of patients' care similarly to patients. This study aimed to (1) quantify the level of agreement between patients' and caregivers' reports on the quality of patients' care and (2) determine how the level of agreement varies by caregiver and patient characteristics. ...
