As utility companies use various mechanisms of Demand Side Management (DSM) to regulate and modify consumer demand for energy, manufacturing plants also look for ways to improve the quality/cost ratio by saving energy cost. Several approaches are available for a plant to save energy, one of which is to reschedule the operation hours of electrical devices and take advantage of incentives and favorable pricing offered by utilities. This paper attempts to develop a load optimization model for plants to minimize the cost incurred by energy consumption. Many practical factors are considered in the model, such as electrical device clustering, night schedule extra labor charge, devices with fixed operation schedules, etc. A discussion of solutions to the optimization model is presented. An online tool for energy assessment and load optimization is also briefly introduced.

I review a recent remarkable discovery made by Gamayun, Iorgov, Lisovyy. They found that the Painleve tau functions have Fourier expansions in terms of four point Virasoro conformal blocks. As a result, since Virasoro conformal blocks correspond to the Nekrasov partition functions of a certain class of 4d supersymmetric gauge theories, the Painleve tau functions has explicit series expansions.

When be an array of rowwise extended negatively dependent subgausian random variables we study the strong law of large numbers of weighted sums under some appropriate conditions, whereis an array of constants. Finally, we give some corollaries.

First, I'd like to explain Littelmann's path models. Let be a symmetrizable Kac-Moody algebra (such as, etc.). In the papers "A Littlewood-Richardson rule for symmetrizable Kac-Moody algebras (1994)" and "Paths and root operators in representation theory (1995)", Littelmann introduced Lakshmibai-Seshadri (LS) paths of shape λ (where λ is an integral weight for), and gave the set of them a crystal structure in terms of his root operators; Kashiwara and Joseph proved independently that if λ is dominant, then the crystal of LS paths of shape λ is isomorphic to the crystal basis of the integrable highest weight module of highest weight λ. Using Littelmann's path model (consisting of LS paths), we can describe

The difference between quantum sl_n and quantum gl_n is just an extra generator in the zero part. However, that in the affine case is huge. We have developed a new approach to study the structure and representations of quantum affine gl_n. In the series of talks, I will discuss the entire theory including a new realisation, the Lusztig form and the representation theory of affine q-Schur algebras

For a fibration f: X → Z over the filed of complex numbers, Iitaka conjectures κ(X) ≥ κ(Z) + κ(F), where F is the geometric generic fiber of f and κ denotes the Kodaira dimension. The conjecture is usually denoted by Cn,m, n=dim X, m=dim Z. We will introduce the progress of the conjecture on a positive characteristic field, including the recent results of Cn,n-1 and C3,1 on a positive characteristic field. These are joint work with Lei Zhang and Caucher Birkar.

Solutions of an algebraic differential equation have a rich geometric structure. In his landmarking speech in 1900, Hilbert described a problem on the existence of Fuchsian type equation having prescribed monodromy group, which is now named the Hilbert’s 21stproblem. In this talk, I will introduce Grothendieck school’s formulation and solution of this problem.
