The Dilemma-Zone Calculation

Yellow traffic lights provide opportunities for applied mathematicians. Please witness this research announced more than half a century ago.

"Amber signal light in traffic flow", Denos Gazis [Here there are thrilling audiences], Robert Herman and Alexei Maradudint, Operations Research, vol. 8, No. January 1960, pages 112 - 132. The authors of Communications Automotive in Warren, Michigan, explain as follows.

"Theoretical analysis and observation of the driver's behavior facing the amber signal, the following question was discussed: In the face of an inappropriate timing amber phase, the driver himself, amber You may find the color at the beginning of the phase safely or comfortably so as not to get too close to the intersection, but it is far too far to cross the intersection before the red light begins and the approach speed problem at the intersection The standard of amber signal phase design that can avoid these "difficult areas" to ensure the overall safety of the intersection.

"The attitude that many drivers take is that there is no sacred speed limit! ... [Simple calculation], even if the driver accelerates beyond the speed limit, he still has not eliminated the dilemma I can not understand it. "

This will return to the dilemma that the way the bridge was constructed and completed five days ago collapsed like this. According to the Florida Department of Transportation (FDOT) - engineers asked to build a bridge - calling on them to leave a message - they realized that there was a crack in the structure and would like to discuss it further . As a result of the investigation, it caused a serious collapse, so the university has pledged to comply with the regulations set by the National Traffic Safety Commission - the investigators begin collecting evidence at the crash site including a part of the bridge did.

Date calculation in the context of this blog post refers to the process of calculating dates for different dates. For example, if there is no background of the value of "today", "yesterday" is meaningless. Today's time zone is even more complicated. I may not be in Hong Kong today in Los Angeles today.

In order to perform the basic calculations we consider that we are required for cortical intelligence processing, the neuron must have two attributes. First, it must have an integrated area, in particular a near-end area, a far end area and a top end area. In the brain, neurons receive different signals in these areas, which means they are different. Second, it must have a predicted state. The ANN neuron model lacks the critical condition. Instead of selecting either active or inactive, you need to add another predictive state. This means that in the case of the current connection the neuron will be predicted the next time it starts up. This is an important part of bio-intelligence

Process Improvement One of the most important aspects of a project is the time it takes to get results. The importance and calculation of ROI of process improvement project tend to be overlooked. The dilemma is that the individuals involved are not usually financial analysts and may not have much experience in calculating financial indicators such as NPV (net present value). Another major dilemma or restriction factor is to measure the actual amount of selected content. According to the APQC (American Productivity and Quality Center), you can collect hundreds of different metrics to measure the performance of an organization's processes. When measuring performance, it is important to understand what kind of information you need to collect. Another major consideration is whether the process being measured is tangible or intangible. We recommend you to easily determine the ROI of the process project. It is best to be rustic.
