Higher string functions, higher-level Appell functions, and the logarithmic ^sl(2)_k/u(1) CFT model
, 2007 We generalize the string functions C_{n,r}(tau) associated with the coset ^sl(2)_k/u(1) to higher string functions A_{n,r}(tau) and B_{n,r}(tau) associated with the coset W(k)/u(1) of the W-algebra of the logarithmically extended ^sl(2)_k conformal field

Network decomposition techniques for resource-constrained project scheduling
, 2016 Numerous exact algorithms have been developed for solving the resource-constrained project scheduling problem. Experimental studies have shown that currently even projects with only 60 activities cannot be optimally solved within a reasonable amount of ...

Multivectorial strategy to interpret a resistive behaviour of loads in smart buildings [PDF]
, 2018 In Smart buildings, electric loads are affected by an important distortion in the current and voltage waveforms, caused by the increasing proliferation of non linear electronic devices.

Transitions in labour market status in EU labour markets
, 2014 We discuss the ease with which individuals can move between employment, unemployment and inactivity over time in the EU. Transitions from unemployment and inactivity back into employment are relatively weak in Central Eastern, Mediterranean and ...

A Study of the Effect of Labor Force Productivity on Unemployment in Iran [PDF]
مدیریت بهره وری, 2014 Unemployment is classified as one of the most serious obstacles to economic and social progress. So to avoid the negative effects of unemployment, reducing the rate of unemployment should be considered as one of the leading development goals in ...

Proactive resource allocation heuristics for robust project scheduling. [PDF]
The well-known deterministic resource-constrained project scheduling problem (RCPSP) involves the determination of apredictive schedule (baseline schedule or pre-schedule)of the project activities that satisfies the finish-start precedence relations and ...

Permutation and Grouping Methods for Sharpening Gaussian Process Approximations
, 2018 Vecchia's approximate likelihood for Gaussian process parameters depends on how the observations are ordered, which can be viewed as a deficiency because the exact likelihood is permutation-invariant.
