Two frameworks are proposed for extremum seeking of general nonlinear plants based on a sampled-data control law, within which a broad class of nonlinear programming methods is accommodated. It is established that under some generic assumptions, semi-global practical convergence to a global extremum can be achieved. In the case where the extremum seeking algorithm satisfies a stronger asymptotic s

In strategic management, the concept of organizational capabilities appears in two sets of related literatures: the resource-based view and the dynamic capabilities approach. The resource-based view treats organizational capabilities as unitary factors that explain cross-sectional industry performance differentials. The dynamic capabilities approach, on the other hand, treats organizational capabi

The knowledge concerning electricity consumption, and especially load demand, in Swedish commercial buildings is very limited. The current study deals with methods for electricity consumption indicator development and application of the different methodologies on measured data. Typical load shapes and consumption indicators are developed for four different types of commercial buildings: schools, h

Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. Depending on the specific application, anion or proton exchange membranes with g

Elsystemet står inför en stor förändring som kommer av omställningen till ett utsläppsfritt samhälle. Elsystemet är en central del av vår samhälleliga infrastruktur och dess utveckling har till stor del styrts av politiska beslut även om marknaden fått allt större utrymme sedan 1990-talet. Stora tekniska system utvecklas alltid i samklang med samhällets institutioner där samhällets ramar och regl

Scan circuit testing generally causes excessive switching activity compared to normal circuit operation. This excessive switching activity causes high peak and average power consumption. Higher peak power causes, supply voltage droop and excessive heat dissipation. This paper proposes a scan cell reordering methodology to minimize the peak power consumption during scan shift operation. The propose

It has been suggested that neural mechanisms may contribute to effects of the incretin hormones, and, therefore, also to the effects of dipeptidyl peptidase (DPP-4) inhibition. We therefore examined whether muscarinic mechanisms are involved in the stimulation of insulin secretion by DPP-4 inhibition. Fasted, anesthetized mice were given intraperitoneal saline or the muscarinic antagonist atropine

The purpose of this work is the investigation of some constitutive and configurational aspects of phenomenological model formulations for a class of materials with history-dependent gradient microstructure. The assumption that the behavior of a material point is affected by history-dependent processes in a finite neighbor of this point yields an extended continuum characterized by non-simple mater

BACKGROUND: We report the surgical treatment of a consecutive series of scan negative patients with the intention of unilateral parathyroid exploration with the aid of intraoperative quick PTH (qPTH).MATERIALS AND METHODS: The study included 35 consecutive sestamibi scan negative patients (27 women, eight men) with sporadic pHPT subjected to first time surgery. Median age was 70 years and median p

High resolution photoemission applied to the C 1s and Rh 3d core levels has been used to investigate the adsorption sites at low temperature of CO on the Rh(111) single crystal surface as a function of CO coverage. Two different sites are found to be occupied by the CO molecules. At coverages up to 0.5 monolayers the majority of the molecules are found to adsorb in on-top sites whereas at higher c

The International Aid Transparency Initiative (IATI) is an agreement establishing a common standard for the reporting of information about aid and development funding. Signatories include nations, intergovernmental organizations (IGOs), nongovernmental organizations (NGOs), civil society organizations (CSOs) and private foundations, which together account for approximately 80 per cent of all inter
