Since the premium prices of yard trucks and significantly daily volatility of containers serving demand, it is an uneconomic method to keep a full team of fleet to cover the entire service. Some of the transportation services are outsourced to other external companies. The strategy of outsourcing yard trucks is a decision making problem that container terminals are currently facing. Yard truck ...

The Saccharomyces cerevisiae Rad24 and Rad17 checkpoint proteins are part of an early response to DNA damage in a signal transduction pathway leading to cell cycle arrest. Rad24 interacts with the four small subunits of replication factor C (RFC) to form the RFC-Rad24 complex. Rad17 forms a complex with Mec3 and Ddc1 (Rad1731) and shows structural similarities with the replication clamp PCNA. T...

Wheel loader transmissions are commonly based on a torque converter and an automatic gearbox. This solution is mechanically robust and well suited for the typical operation of the machine, but the fuel efficiency is low at some modes of operation. One proposed improvement is to replace the present transmission with a multi-mode power-split CVT (MM-CVT). This paper compares the fuel saving poten...

The loader was developed on top of the existing Parallel Data Query (PDQ) iterator infrastructure. The loader and converter are iterators. The server treats the load iterator tree just like any other iterator tree and is able to use existing algorithms for parallelization and resource allocation. This also allows the loader functionality to have low level access to SQL functions. The XPS loader...

This paper describes an autonomous navigation system for a large underground mining vehicle. The control architecture is based on a robust reactive wall-following behaviour. To make it purposeful we provide driving hints derived from an approximate nodal-map. For most of the time, the vehicle is driven with weak localization (odometry). This need only be improved at intersections where decision...

Feasibilities of heat and cold storage technologies for vehicles were discussed for improvement of vehicle fuel efficiency. Energy performance of a plug-in cold thermal energy storage system, in which ice slurry is produced at a stationary chiller and charged into a tank in a vehicle for cabin and cargo cooling, was discussed. Energy balance of the plug-in system was compared with onboard heat ...

A person’s ability to perform a task is often limited by their ability to maintain balance. This is particularly true in lateral work performed in seated environments. For a truck driver operating the shift lever of a manual transmission, excessive shift forces can necessitate pulling on the steering wheel with the other hand to maintain balance, creating a potentially unsafe condition. An anal...

The power management controller of a hybrid vehicle orchestrates the operation of onboard energy sources, namely engine and auxiliary power source with the goal of maximizing performance objectives such as the fuel economy. The paper focuses on optimization of the power management strategy of the refuse truck with parallel hydraulic hybrid powertrain. The high power density of hydraulic compone...

Clamp loaders load ring-shaped sliding clamps onto DNA where the clamps serve as processivity factors for DNA polymerases. In the first stage of clamp loading, clamp loaders bind and stabilize clamps in an open conformation, and in the second stage, clamp loaders place the open clamps around DNA so that the clamps encircle DNA. Here, the mechanism of the initial clamp opening stage is investiga...
