Employment is one of the bread-and –butter issues requiring urgent attention and careful handling. With the accelerating of the urbanization, a large number of surplus labors have appeared in rural areas of China. At the same time, in the course of the deepening reform of state-owned enterprises, there are more and more laid-off workers, so the problem of unemployment sticks out. In this paper,...

An inventory model for a deteriorating item with price sensitive demand is developed under deterioration rate, which is assumed to follow weibull distribution with known parameter. In addition, we allow for multiple price changes about an item, but the number of price changes isn’t given. The purpose of this paper is to find the optimal number of price settings, the optimal dynamic prices and t...

By making use of the approximation method, we obtain the existence and regularity of the viscosity solutions for the generalized mean curvature flow. The asymptotic behavior of the flow is also considered. In particular, the Diri...

The design studio 'Flying Bricks' was held during the summer semester 2015. Its main objective was to redesign an existing building with the use of facing bricks algorithmically, utilizing algorithmic thinking and programming as a means for form generation. The purpose of having students express their designs in terms of code was to emphasize problem thinking over solution generation, which has...

In this paper we consider a free boundary problem which is used to describe the motion of contact lines of a liquid droplet on a flat surface. The elliptic nature of the equation for droplet shape and the monotonic dependence of contact line velocity on contact angle allows us to introduce a notion of “viscosity” solutions for this problem. Unlike similar free boundary problems, a comparison pr...

i2b2 has proven to be a valuable tool for a variety of tasks in clinical and translational research. But to establish an extended IT infrastructure, several clinical information systems have to be connected seamlessly and routine data integration processes have to be defined. In this position paper, we will outline a number of options that would enhance the existing software stack with regards ...

The nonnegative viscosity solutions to the infinite heat equation with homogeneous Dirichlet boundary conditions are shown to converge as t → ∞ to a uniquely determined limit after a suitable time rescaling. The proof relies on the half-relaxed limits technique as well as interior positivity estimates and boundary estimates. The expansion of the support is also studied.

Patrolling games were recently introduced by Alpern, Morton and Papadaki to model the problem of protecting the nodes of a network from an attack. Time is discrete and in each time unit the Patroller can stay at the same node or move to an adjacent node. The Attacker chooses when to attack and which node to attack, and needs m consecutive time units to carry it out. The Attacker wins if the Pat...

Rosamine derivative RC-1, bearing macrocyclic ligand [15]aneNO(2)S(2) as receptor, was synthesized as an enhanced fluorescent chemosensor for Ag(+) in absolute aqueous solution. The fluorescence images in living cells show the potential application of RC-1. The difference of fluorescence enhancement process after binding with Ag(+)/Hg(2+) in acetonitrile/water solution was first proved by theor...

We introduce a new notion of viscosity solutions for the level set formulation of the motion by crystalline mean curvature in three dimensions. The solutions satisfy the comparison principle, stability with respect to an approximation by regularized problems, and we also show the uniqueness and existence of a level set flow for bounded crystals.
