Background and purpose: Vibration caused by ventilation systems in buildings is one of the harmful physical factors that can cause harm to residents. Therefore, measuring and controlling vibration is important. Materials and Methods:  In the first step of the study, the vibration accelerometer was placed on the base of a fan where the vibrations were sent toward the duct wall. A vibration asse...

Background. This paper investigates the pillars of content strategy and fan engagement in social networks during 2018 PyeongChang Winter Olympics and Paralympics. Objectives. The purpose of this paper is to seek reasons behind the differences in fan engagement in social media channels of PyeongChang Winter Olympics and Paralympics. Methods. Facebook and YouTube channels are used to analyze en...

During a one-year period, a total of 6,305 blood cultures were processed in a tertiary-care teaching hospital; 6 to 12 ml of blood was inoculated into both a BacT/Alert Fan aerobic bottle and an ESP 80A aerobic bottle. The FAN aerobic bottle contains an antimicrobial-absorbing material; the 80A aerobic bottle does not. Bottles were processed on their respective continuous-monitoring blood cultu...

The degradation in efficiency of auxiliary components in heating/cooling systems when operating at part load is frequently reported. Through the use of variable speed components, the supplied capacity can be reduced to match the required load and hence reduce unnecessary energy consumption. However, for fan coil units, difficulties can arise when optimizing fan and pump speeds at part load. Pra...

We prove that the correlation of a depth-d unbounded fanin circuit of size S with parity of n variables is at most 2−Ω(n/(log S) ).

A fundamental problem in the design of speed-independent asynchronous circuits is the decomposition or splitting up of high-fanin operators into two or more lower-fanin operators. In this paper, we develop general techniques to decided whether a particular decomposition of an arbitrary state-holding or combina-tional element into two elements with an isolated internal signal is correct. These t...

We consider depth-3 unbounded fanin threshold circuits. Gates are usual threshold functions T n k which compute 1 ii at least k of the inputs are equal to 1; the minimum minfk; n ? k + 1g is the threshold value of this gate. We show that the function T n k cannot be computed by a small depth-3 threshold circuit with threshold values of its gates much smaller than k:
