The electrification of loader designs can utilise several power motor types. Hence, this study investigates the operational performance pure electric-powered loaders matched with three types motors. Firstly, for ZL08 loader, it is proposed that a structure adopts two motors to drive walking and hydraulic systems separately. Secondly, dynamic parameters were matched, then, joint vehicle dynamics...

to investigate how the buying behavior of firms work is always needed, since it is an every changing process influenced by many forces in its surroundings. industrial firms tend to have a smaller number of customers which means that they are easier to identify than customers in consumer markets. effective marketing strategy relies on understanding consumers and their needs. this understanding m...

This work studies an innovate working hydraulic system design for mobile applications, referred to as flow control. The fundamental difference compared to load sensing systems is that the pump is controlled based on the operator’s command signals rather than feedback signals from the loads. This control approach enables higher energy efficiency since the pressure difference between pump and loa...

This thesis deals with innovative working hydraulic systems for mobile machines. Flow control systems are studied as an alternative to load sensing. The fundamental difference is that the pump is controlled based on the operator’s command signals rather than feedback signals from the loads. This control approach enables higher energy efficiency and there is no load pressure feedback causing sta...

The archaeal and eukaryal clamp-loader and clamp proteins were investigated with the evolutionary trace method. The molecular phylogeny of the proteins suggested that the hetero-pentameric complex of the archaeal clamp-loader with two subunits (RFCL and RFCS) was not a preserved ancestral type, but a degenerated version of the eukaryal complex of five subunits (RFC1-5). The evolutionary trace o...

Subunits of the Rad9/Rad1/Hus1 (9-1-1) proliferating cell nuclear antigen (PNCA)-like sliding clamp are required for DNA damage responses and telomerase-mediated telomere replication in the nematode Caenorhabditis elegans. PCNA sliding clamps are loaded onto DNA by a replication factor C (RFC) clamp loader. The C. elegans Rad17 RFC clamp loader homolog, hpr-17, functions in the same pathway as ...

Program transformation through the repeated application of simple rewrite rules is conducive to formal verification. In practice, program transformation oftentimes requires data to be moved throughout the program structure. This article explores the use of higher-order rewrite rules as the mechanism for accomplishing such data movement. The effectiveness of higher-order rewrite rules is demonst...

Application models for simulation are usually built by combining and configuring a selection of component models into an application model. This can be done by manually editing the model text representations. However, it is usually much easier to use a graphic editor for selecting och connecting components. The MathModelica tool has such a graphic editor, adapted for components in Modelica libr...
