The Research for Management of Water Supply and Drainage in Leadframe Plant

Wang, Jen-hung 17 June 2011 (has links)
The reasearch is to discussice the relationship between water supply and drainage for plan, implement, improvement and management in leadfram plant. The purpose is to discuss and improve the relationship for below coefficients: equipment capability, manufacture target, efficiency and management of water used and role of manufacture department. The major conclusions in this study: 1. It will affect the whole implement result: the ability, target, technology of enviriment manager in the company. 2.It should be controlled any time on the requirement of manufacturing target ,requirement of hardware ability and drafted the expand plan and preparation in advance. 3.For the target of environment management ,we should use the stable improvement method in quality concerned and rule of law followed. 4. For the mass production is the main purpose for a company, we have to communicat with each departments to build the correct thinking for working impelement. The meaning on management of the conclusion in this study: 1.Yield control is the source of competed vantage on same kind products. 2.The equipment plan effects the management and controller of follow-up operation. 3.The accurate execution of maintain plan and the stuff of operators are the key point that effects the yield. 4.The efficiency of equipment is the key point that effects the cost

Correlation of roof loads to wind speed and direction on a post-frame building in real time

Orchard, David 16 January 2012 (has links)
In 2004 a post-frame structure with plastered straw bales as an in-fill wall system was built at the University of Manitoba. Load cells installed at the top and bottom of ten eave wall posts were intended to measure the tributary load transferred from the roof structure into the supporting posts. In 2011 wind speed and direction were measured adjacent to the structure and correlated to simultaneous load data. A linear regression model relating load to wind speed within four directional quadrants revealed that load behaviour was inconsistent with design-level loading prescribed by the National Building Code of Canada (2005). A second regression model with both speed and direction as independent variables did not determine any statistically significant relationships. This research concluded that the initial assumptions made in 2004 required additional scrutiny, including the conditions under which the load cells were calibrated, and the structural contribution of the walls’ plastered skins.

Adaption layer enhancement : an investigation of support for independent link ARQ

Ang, Eng Soon January 2003 (has links)
The most commonly used transport protocol, TCP (Transport Control protocol) reacts to loss by throttling the transmission rate. This impacts performance if the loss is non-congestion related, corruption loss. A link layer protocol may use ARQ to provide reliability and shield TCP from corruption loss. The advantage of fragmentation together with link ARQ is; it is able to retransmit the requested frame and instead of the entire data packet. For a link to perform transparent fragmentation, an adaption layer (AL) protocol is needed. Although link ARQ may improve TCP performance, it introduces undesirable delay (i.e. receiver side head of line blocking) and negatively impacts the end-to-end TCP performance. This thesis presents new results on the impacts link ARQ have on the <i>cwnd </i>(congestion window) limited TCP sessions sharing the same link ARQ. To minimise the delay, we proposed to use a more assertive link layer protocol (APRIL). To eliminate the interaction between classes of flow sharing the link with ARQ, flow isolation is required. We discussed the role of the virtual channel (VC) and how it can be used to provide flow isolation. We identified the role of the VC as related to the reassembly process at the receiver end. It allows different traffic classes/flows to be reassembled independently. Therefore, multiple reassembly processes are desirable, one for each traffic class/flow. Our novel approach performs reassembly in the link receive buffer, without demultiplexing frames into the respective channel (as in ATM and X.25) to eliminate the interaction between flows sent on different virtual channel. An approach to increase the robustness of sequence number wrapping in a VC reassembly process without increasing the protocol overhead is also proposed. The inefficiency in the multiple reassembly processes is discussed in the thesis. A simple reassembly process requires massive CPU effort at the receiver since it does not know what exists in the buffer before the process is triggered. We proposed the use of three lists, channel, retransmission and suspended list to minimise this inefficiency in the multiple reassembly processes. During link layer frame processing, it updates all the VC encountered in the block in the channel and retransmission lists. The adaption layer can refer back to these lists prior commencing reassembly process. Therefore, irrelevant blocks, frames and VC can be identified and ignored during the reassembly process. We demonstrate that these lists greatly reduced the processing cost.
