Frequent inlet flow changes, especially in the same direction, typically cause problems for averaging level controllers. To obtain optimal flow filtering while being robust towards future inlet flow upsets closed loop robust MPC has been used. It differs from other averaging controllers in that it does not return the tank level to a fixed set-point, but rather lets it depend on the current inle...

Biodegradation of chloroform along with a mixture of VOCs (methanol, ethanol, acetone and toluene) commonly found in pharmaceutical emissions using a biotrickling filter (BTF) was evaluated. The performance of the BTF was evaluated for both steady and transient conditions, for different inlet loading rates (ILR), empty bed residence time (EBRT) and inlet chloroform concentrations. Among the VOC...

ions A first-order abstraction in the ρpg-calculus consists of two object port graphs for the leftand the right-hand sides, and an arrow node embedding the correspondence between the two sides. The arrow node has two particular ports, a handler port p0 and a black hole port bh. Some restrictions must be imposed on the connectivity of these two types of ports. A handler port can be connected onl...

Background In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. Methods A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2...

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...

This paper considers tbe rearrangement process in the twostage btoadcast switching network presented by F. IC. Hwang and G . W. Richards in IEEE TRANSACTIONS ON COMMUNICATIONS, October 1985. By defining a certain function it is possible to calculate an upper bound on the number bf connections to be moved during a rearrangement. When each inlet channel appears twice, the maximum number of connec...

BACKGROUND To investigate the effects of postoperative radiotherapy (PORT) on the survival of patients with resected stage IIIA-N2 non-small cell lung cancer (NSCLC). METHODS A total of 3,334 patients with resected stage IIIA-N2 NSCLC in 2004 to 2013 were identified in the Surveillance, Epidemiology, and End Results database and stratified according to use of PORT. Propensity score-matching (...
