In this paper we introduce a new Packing problem, the Three-Dimensional Knapsack Problem with Balancing Constraints (3BKP), the extension of the ThreeDimensional Knapsack Problem (3KP) where additional constraints related to the packing center of mass are given. The 3BKP consists in orthogonally packing a subset of threedimensional weighted items into a knapsack in order to maximize the total p...

Functional differential equations of advanced type with piecewise constant argument deviations are studied. They are closely related to impulse, loaded and, especially, to difference equations, and have the structure of continuous dynamical systems within intervals of unit length.

The aim of education is to provide the basis for life long learning and improvement. In this direction, schools and universities offer standard curricula aiming to cover the fundamental needs of their students in a few years scope. On the other side, institutes and companies offering life long education focus on improving specific skills and competencies of people in a short period of time. Obv...

Problem, research strategy, and findings In many U.S. metropolitan areas housing costs have skyrocketed in recent years relative to average incomes. A worsening shortage of affordable these metros may push households away from job-rich cities expensive neighborhoods into outlying areas, where is cheaper but jobs are more distant. To examine this issue, we revisit the jobs–housing balance, a pop...
