The throughput maximization problem of wireless mesh access networks is addressed. For the case ot cooperative access points, we present a negotiation-based throughput maximization algorithm which adjusts the operating frequency and power level among access points autonomously, trom a gametheoretical perspective. We show that this algorithm converges to the optimal frequency and power assignmen...

Many of fossil power plants, which were constructed during 1960's and 70's and exceed more than 10,000 working hours, have presently been operating while they have been receiving progressive damage, mainly from creep, as the time proceeds.[I, 2] Furthermore, by shifting the base load of power from fossil power plants to nuclear power plants, they are faced to even more severe operating conditio...

We describe a synthesis system that takes operating range constraints and inter and intracircuit parametric manufacturing variations into account while designing a sized and biased analog circuit. Previous approaches to computer-aided design for analog circuit synthesis have concentrated on nominal analog circuit design, and subsequent optimization of these circuits for statistical fluctuations...

This paper presents a new predictive power-factorcorrection (PFC) controller for series-interleaved three-level boost (TLB) converters. Compared to the state-of-the-art TLB PFC controllers, where a two-cycle prediction and a detection of an operating region are necessary, the proposed controller achieves a low total harmonic distortion of the input current by using a single equation to predict ...

background and purpose: upon centuries, wars have taken over countries due to theadvancement of sophisticated warfare,causingserious injuries among soldiers. nurses are directly involved in preoperative and postsurgical patient care. one of the most remarkable contributions of the iranian operating room nurses was to provide medical care for wounded soldiers in field hospitals during the iran-i...

This paper empirically studies the impact of the adoption of open source software (OSS) on firms’ labor productivity and innovative behavior. Using a representative sample of German firms, the results show that the adoption of OSS operating systems for servers and general OSS applications has no impact on firm level labor productivity, while the adoption of OSS operating systems for PCs impacts...

As recently recognized, distillation columns, operating with reflux and boilup as independent inputs, may have multiple steady-state solutions, even in the ideal binary case. Two fundamentally different sources may cause the multiplicity, and in both cases some operating points are found to be unstable. This article provides evidence for the instability and discusses the effect of operating con...

This paper describes a simulation-based analysis of a printed circuit board (PCB) testing process. The PCBs are used in a defense application and the testing process is fairly complex. Boards are mounted on a test unit in batches and go through three thermal test cycles. As boards fail testing during the thermal cycling, operators can either replace the failed boards at fixed points during the ...

The paper presents a new approach to the generation of test signals used in service diagnosis. The tests make it possible to isolate faults, which are isolable only if the system is brought into specific operating points. The basis for the test signal selection is a structure graph that represents the couplings among the external and internal signals of the system and the fault signals. Graph-t...
