Performance evaluation of a thermodynamic system under off-design conditions is very important for reliable and cost-effective operation. In this study, an off-design model of an organic Rankine cycle driven by solar energy is established with compound parabolic collector (CPC) to collect the solar radiation and thermal storage unit to achieve the continuous operation of the overall system. The...

We aimed to develop alternative fishing gear for catching the common octopus, to decrease the use of bait and operating costs in comparison to commercial net pots. A tubular-type pot was designed, and behavioral responses of the common octopus were experimentally monitored in tank and replicated 10 times to compare fishing performances between 300 experimental and 300 commercial net pots in the...

Off-peak backgrounds Typically background is characterized in EPMA by measuring the x-ray intensities on either side of the analytical peak and interpolating the value underneath the x-ray peak. This interpolated intensity is then subtracted from the peak intensity to produce a background corrected net intensity for the element in question. Care must be taken to avoid interferences with the off...

Scholars investigating the relationship between the Internet and social capital have been stymied by a series of obstacles, some due to theoretical frameworks handed down unchanged from television research, and some due to the lack of an appropriate yardstick. For example, the social interactions that occur through television are prima facie different from those that occur online. Given this ba...

In real investment, there is a relationship between external financing and abnormal stock returns. This study predicts a negative correlation between external financing and stock returns. The dependent variable of the research is stock returns and the independent variables are net financing and equity ratio. Also, control variables of the research includes assets growth, company’s size and comp...

enterprises that adopt BYOD (Bring Your Own Device) need to optimize network selection for refundable employees’ business usage. They can ‘force-on-net’ business sessions when employees are on-site and seek ‘best connection’ when employees are off-site, perhaps via hospitality partners that provide WiFi connectivity. For non-fundable, unproductive personal usage, service requests should be ‘for...

This note shows by means of simple counterexamples that some key results presented by He and Lemmon on the liveness verification and enforcing of Petri nets using unfolding are incorrect. As a result, the applicability of unfolding for Petri net supervision is still an open issue. 1 Introduction Recently, He and Lemmon have presented an original approach for the analysis and control of bounded ...
