A system and method provide for measuring the effectiveness of online advertising using reach, frequency and effective reach. The system is able to count a user access, even it is served from a cache. The system is further able to distin... A Botelho,Roy S. de Souza - US 被引量: 26...
Having frequent intercourse around the day of ovulation will allow for plenty of sperm to be present. This strategy maximises the chances that one sperm cell will reach the egg and fertilise it. Male fertility supplements combine many key nutrients to create one powerful fertility-enhancing pill. ...
Historical method: This approach calculates VaR based on the frequency and magnitude of historical returns Parametric method: This approach assumes that the returns follow a specific distribution and uses the distribution parameters to calculate the VaR Monte Carlo simulation: This approach simulates a ...
This 10 Hz fundamental frequency is easily distinguished in the freight vibration data; but one can argue it's a bit harder to see in the UPS ground vibration data. This may be due to the poorer coupling between the accelerometer and the trucks' tires; and the general bouncing around of ...
aFurthermore, the whole running efficiency can be improved to reach the goal of saving energy sources. Therefore, external-rotor PMSM has an extensive potential application in the field of low speed drive. 此外,可以改进整体连续效率到达挽救能源的目标。 所以,外部电动子PMSM有一种广泛的潜在的应用在...
If the CAC is $500, and the LTV is $350, the business would lose money on the customer. In this way, the CAC is an indicator of the lowest LTV needed to reach profitability. While the LTV is a key part of balancing the basic profit equation, it can also calculate comparative LTV...
Go tohttp://localhost:8081(admin/password) and check theobservertc-reportsdatabase. You should see new data come in every 30 seconds – the default observer-to-database reporting frequency unless you change it. Before we go to analyze the reports, take a look at thedocker-compose.yamlfile...
You can do this by looking at your customer base and finding the average number of years they spend as a customer of your brand: Total Customer Lifespans / Number of Customers 5. Calculate customer lifetime value Use the customer lifetime value calculation to reach a final figure: Customer ...
To calculate the spectral properties of the model, boundary-mode analyses and a frequency-domain study are run using the specialized modeling features for wave optics. Below, you can see a field plot of the resonant wavelength. These results show that when the field in the straight waveguide in...
