This paper proposes a new frequency domain method to model the heat transfer between the injected/extracted heat and the temperature of the fluid exiting a borehole heat exchanger. The method is based on in situ measurements and focuses particularly on the short-term borehole heat transfer. It uses a rational function of the Warburg variable in the Laplace domain to model the borehole heat transfe
An experimental study has been conducted to investigate if a new and simple system, that is, stripes of high-bright dynamic green LED lights installed on the floor, can support people way-finding in smoke-filled railway tunnel evacuations. The impact of way-finding installations on people evacuation (intended as people movement paths and evacuation times) has been studied using Oculus Rift, a head
This paper develops and tests a motivational model to explain the overall continuance intention to use computers and smartphones. Based on survey data from 192 undergraduate students, structural equation modeling analysis is used to report: (1) the independent effect of intrinsic motivation on the continuance intention to use computers and smartphones; (2) the independent effect of extrinsic motiv
The impact of BRICS (Brazil, Russia, India, China, and South Africa) and other emerging economies on the field of international development has seen traditional donor nations wrestle with fundamental shifts in the geometry and makeup of the donor community. This has resulted in asymmetrical power relations in organizations such as the Organisation for Economic Co-operation and Development (OECD) f
When the GREAT campaign was announced in 2011, we were still in theera of New Public Diplomacy, and were wrapped up in the potentialof digital media to change the diplomatic landscape. Interconnectedglobal publics were supposed to solve wicked global problems likeclimate change through inclusion and dialogue; by sharing knowledgeand working together to shape social change. The role of governmentsw
AIM: To prospectively validate two mathematical models for calculating the likelihood of endometrial malignancy in patients with postmenopausal bleeding (PMPB), sonographic endometrial thickness (ET) ≥4.5 mm and no fluid in the uterine cavity.METHODS: This is a prospective observational diagnostic validation study performed in a PMPB clinic in a university hospital. Of 860 consecutive patients, 35
This article proposes a new panel unit root test based on the generalized method of moments approach for panels with a possibly small number of time periods, T, and a large number of cross-sectional units, N. In the model that we consider the deterministic trend function is essentially unrestricted and the errors obey a multifactor structure that allows for rich forms of unobserved heterogeneity.
The structure, biosynthesis, and metabolism of proteoglycans in the HL-60 human promyelocytes were studied by metabolic labeling in culture with [35S]sulfate, [3H]glucosamine, [3H]serine, and [3H]leucine. These cells synthesize a single predominant species of intracellular proteoglycan with an approximate molecular weight of 100,000. The cells contain about 1 μg of proteoglycan/million cells. The
Although code-switching has attracted a considerable amount of attention for quite some time, the issue of linguistic switch in foreign language teaching has not been a major subject of scientific study. Using a qualitative approach to individual examples of linguistic switch among three second language teachers of French in Sweden, this article, although highly preliminary, attempts to highlight
