“…Moreover, the vague information from subjective estimations is influential in the decision process, and the uncertainties can hardly be reflected by intervals [2]. Fuzzy sets are effective at reflecting the vague information from subjective estimations in the real world [29]. Thus, a FLP model is formulated below:…”

“…Therefore, many inexact optimization methods, such as interval, fuzzy, and stochastic programming methods, have been proposed for dealing with uncertainties that exist in MSW management problems [13][14][15][16][17][18][19][20][21][22][23][24]. Among them, the fuzzy linear programming (FLP) method, which is recognized as an effective alternative to tackle uncertainties expressed as fuzzy sets, has been widely studied over the past decades [25][26][27][28][29][30][31][32][33][34]. For example, Huang et al [26] proposed a grey fuzzy linear programming approach for MSW management planning.…”

A fuzzy random conditional value-at-risk-based linear programming (FCVLP) model was proposed in this study for dealing with municipal solid waste (MSW) management problems under uncertainty. FCVLP improves upon the existing fuzzy linear programming and fuzzy random conditional value-at-risk methods by allowing analysis of the risks of violating constraints that contain fuzzy parameters. A long-term MSW management problem was used to illustrate the applicability of FCVLP. The optimal feasibility solutions under various significance risk levels could be generated in order to analysis the trade-offs among the system cost, the feasibility degree of capacity constraints, and the risk level of waste-disposal-demand constraints. The results demonstrated that (1) a lower system cost may lead to a lower feasibility of waste-facility-capacity constraint and a higher risk of waste-disposal-demand constraint; (2) effects on system cost from vague information in incinerator capacity inputs would be greater than those in landfill capacity inputs; (3) the total allowable waste allocation would vary significantly because of the variations of risk levels and feasibility degrees. The proposed FCVLP method could be used to identify optimal waste allocation scenarios associated with a variety of complexities in MSW management systems.

“…ERAHERTZ vacuum electronic devices (VEDs) are highly potent radiation sources known, which promise to enable higher power and efficiency than laser or semiconductor sources [1][2][3][4][5]. Among such devices, compact and powerful extended interaction devices (EIDs) have shown great potential in plasma diagnostics, spectroscopy, and military applications due to their high gain per unit length [1,[6][7][8][9][10][11][12]. With the characteristics of both slow-wave structure (SWS) and coupled cavities, extended interaction oscillator and extended interaction klystron (EIO & EIK) combine the advantages of traveling wave tubes (TWTs) and conventional multi-cavity klystrons.…”

An improved topology of Extended interaction oscillators (EIO) is presented with enhanced efficiency at 0.35 THz. A bi-periodic ladder-type structure is used for optimizing the performance of the TM31-2π mode operation. The proposed topology is based on bi-periodic interaction gaps composed by staggered short and long slots. The bi-periodic interaction mechanism permits to operate the circuit with a standing-wave field between the π and 2π modes, thus providing the potential to combine the advantages of both π and 2π modes in terms both of coupling and output performance. The resulting transverse TM31 operating mechanism exhibits a good agreement with bi-periodic structure in terms of coupling performance, with the short slot length positively correlated with the value of effective characteristic impedance M 2 R/Q. The optimization of M 2 R/Q and Qe, the circuit demonstrates attractive coupling and output characteristics. A state-of-the-art value M 2 R/Q of 59.69 Ω and a moderate Qe of 2523.52 are achieved for the proposed ladder-type EIO. A RF power of 540 W is obtained with a 42.5 kV, 0.6A sheet beam, with 2.1% electronic efficiency at 0.35 THz.
