This paper presents a novel approach for experimentally simulating various environmental conditions and container parameters on air conditioning and refrigeration (AC&R) systems. The proposed emulation technique uses a hardware-in-the-loop (HIL) system to simulate the loading conditions on the evaporator during experimental testing. The evaporator air inlet conditions are controlled with a smal...

The container pre-marshaling problem (PMP) is an important optimization problem that arises in terminals where containers are stacked in bays before they are collected by vessels. However, if a due container is stacked underneath other containers, it is blocked, and additional relocations are necessary to retrieve the container from the bay, which can cause significantly delays. To avoid this e...

Original scientific paper This paper presents designing of spherical tank using combination of analytical procedure with FEM analysis and experimental testing in order to minimize design time and verify design strength. Analytical procedure for calculation of the tank strength in the initial stages of design process is briefly presented. Based on analytical results, tank is dimensioned and FEM ...

Thermodynamic analysis and numerical modeling of hurricane intensity has shown that its is controlled by the enthalpy transfer from the ocean surface and by drag. Direct measurements of drag, evaporation, and sensible heat transfer are not easily performed on the high seas. Therefore, a wind wave tank has been constructed in which a few aspects of a tropical storm are simulated. The air velocit...

This study presented participants with conditional statements with content that was group-related, container-related, and a combination of group and container. Participants received modus ponens, modus tollens, denying the antecedent, affirming the consequent, and inconsistent forms of conditional arguments. Results demonstrated a significant advantage of the group over the container wording fo...

Leading topic of this article is description of Lorentz forces in the container with cuboid and cylindrical shape. Inside of the container is an electrically conductive melt. This melt is driven by rotating magnetic field. Input data for comparing Lorentz forces in the container with cuboid shape were obtained from the computing program NS-FEM3D, which uses DDS method of computing. Values of Lo...

Container stacking rules are an important factor in container terminal efficiency. We build on prior research and use a discrete-event simulation model to evaluate the impact of a truck announcement system on the performance of online container stacking rules. The information that is contained in the announcement, i.e., the expected departure time for an import container, can be used to schedul...

Containers are ubiquitous in daily life. By container, we consider any physical object that can contain other objects, such as bowls, bottles, baskets, trash cans, refrigerators, etc. In this paper, we are interested in following questions: What is a container? Will an object contain another object? How many objects will a container hold? We study those problems by evaluating human cognition of...

There is an increasing interest in using ultrasonic guided waves to assess the structural degradation of above-ground storage tank floors. This is a non-invasive and economically viable means of assessing structural degradation. Above-ground storage tank floors are ageing assets which need to be inspected periodically to avoid structural failure. At present, normal-stress type transducers are b...

Given a set of k disjoint convex polygonal obstacles inside a triangular container, we add straight-line noncrossing edges such that each obstacle has three vertex-disjoint paths to the container. We prove combinatorial bounds on the minimum number of edges that are always sufficient and sometimes necessary. Figure 1: A triangular container with disjoint convex obstacles.
