The matrix converter instability can cause a substantial distortion in the input currents and voltages which leads to the malfunction of the converter. This paper deals with the effects of input filter type, grid inductance, voltage fed to the modulation algorithm and the synchronous rotating digital filter time constant on the stability and performance of the matrix converter. The studies are ...

This study investigated the effects of different output-based task repetition conditions on EFL learners’ speech act production. Three intact classes of English-major students constituted three instructional groups: (1) the explicit task-repetition (ETR) group, (2) the implicit task-repetition (ITR) group, and (3) the no-input task repetition (NTR) group. All the three groups engaged in t...

Rare earth element (REE) concentrations were determined in 32 rainfall events collected in suburban Tokyo. Two or more samples were collected for 13 events out of 32 events. A pre-concentration method was applied using a chelate resin solid phase extraction column. Good and uniform recoveries for REEs (Y to Lu, 99~101% at pH = 3.7~4.0) were obtained. Detection limits reached as low as 0.001 ng ...

A contingent contract in a transferable utility game under uncertainty specifies an outcome for each possible state. It is assumed that coalitions evaluate these contracts by considering the minimal possible excesses. A main question of the paper concerns the existence and characterization of efficient contracts. It is shown that they exist if and only if the set of possible coalitions contains...

For optimum health and performance, the animal’s diet must contain adequate quantities of all nutrients required, including amino acids. The limiting amino acid is that presents the greatest deficiency relative to its requirement. A shortage of the limiting amino acid will constrain animal growth and reduce feed efficiency [10]. Moreover, there is evidence suggesting that a severe amino acid im...

Six experiments were conducted with 8-d-old crossbred chicks to evaluate the effects of 4% excesses of DL-methionine (Met), L-phenylalanine (Phe), L-tryptophan (Trp), L-lysine (Lys), L-histidine (His), L-threonine (Thr), L-isoleucine (Ile), L-arginine (Arg), L-valine (Val) or L-leucine (Leu) on growth or dietary "choice" (i.e., self-selection) when added to 23% protein corn-soybean meal (C-SBM)...

The aim of the talk is to study the dynamic oligopolistic market equilibrium problem in the realistic case in which we allow the presence of capacity constraints and production excesses and, moreover, we assume that the production function depends not only on the time but also on the equilibrium distribution. As a consequence, we introduce the generalized dynamic CournotNash principle in the el...
