Firefly Algorithm Case Study

The Mega Catch is designed to appeal to all senses more effectively without costing you a lot of money. It is the only trap available that uses a light system that flashes in both a visible and invisible spectrum, a feature which has proven it can be effective at drawing in a variety of bugs. The only true drawback to this type of trap is that propane is able to draw mosquitoes and other insects from slightly further away. Whereas a propane trap can keep an area that is approximately 1 acre, bug-free, the Mega-Catch that does not use propane, will attract bugs in a smaller 3/4 acre or

Overall, the lab provided expected results. Most of our hypotheses were correct, including Dim vs. Red, Dim vs. Blue, and Dim vs. Black. We hypothesized that Drosophila Melanogaster would prefer dim light over all colors, especially blue and black due to the fact that they have very short wavelengths which are lethal to the flies. However, results from 2 out of our 5 trials did not support the hypotheses. In the initial trial, Dim vs. Dim, we expected an equal number of flies on each side of the chamber due to the same lighting on both sides.

90 % down compared with the income of $ 5.7 billion in second quarter of last year. After adjustments the earnings were $ 1.8 billion. Cash flow from operations was $ 7.2 billion. The company sold assets worth $ 1.80 billion in the last quarter. The company’s upstream operations were affected more by the decline in crude oil prices since it resulted in reduced revenues and impairments worth $ 1.96 billion triggered by a downward revision in the company’s longer-term crude oil price outlook.

Relative risk Relative risk is the ratio of two absolute risks. It measures the strength of effect of an exposure (or treatment) on risk. A beneficial treatment will result in a relative risk of less than 1; this can then be subtracted from 1 to give the relative risk reduction. A harmful treatment, or other exposure, will give a relative risk of more than 1. Example: In the following study, over 40 years of follow up, the annual mortality rate from CHD was 572 per 100 000 in non-smokers, and 892 per 100 000 in smokers.

The concern of the study is to know the long-term result of MBCT with the use of standardized measures of depressions (BDI-II), mindfulness (MAAS), and rumination (RSS) and the outcomes are collected yearly for 3 years. Thirty-nine participants were observed and the results showed a significant decrease in depression. Although the depression scores for the last year increased, it was still inside the normal range of BDI-II. Rumination and mind attention showed a strong negative correlation which means as rumination increases, the mind attention decreases and vice versa. It was therefore concluded that continued MBCT aids and training can help relapse prevention.

Data for a recent month for the first department follow: units material labor overhead WIP beginning 5,000 $4,320 $1,040 $1,790 units started in process 45,000 unit transferred out 42,000 WIP ending 8,000 cost added during the month $52,800 $21,500 $32,250 The beginning work in process inventory was 80% complete with respect to materials and 60% complete with respect to labor and overhead. The ending work in process inventory was 75% complete with respect to materials and 50% complete with respect to labor and overhead. Required: Assume that the company uses the weighted-average method of accounting for units and costs. 1. Compute the equivalent units for the month for the first department.

As Forbes states “The Department of Transportation reported that railroad industry costs and prices were cut in half in the decade following deregulation”. That deregulation has continued

The valuation of each firm was derived from forecast of cash flows based on projection of operations over the next few years. The parameters of growth rate of different lines of cash flows were different for both the companies depending upon the company’s business strength. Regarding the rate for discounting of cash flows, the CAPM model is used to estimate the cost of equity and WACC. The long term debt ratio is assumed to decrease with decrease in cost of capital as the project life goes and improvement in the credit rating of the firm. The premium for Motorola share comes around to be 65%.

Many studies have been conducted to test this statement’s validity, as the U.S. Department of Transportation studied energy conservation during daylight saving time in the 1970s, concluding that “America’s electricity usage is reduced by about one percent during each day that daylight savings time is in effect.” (Source B) This is a huge statement as it does not say one percent over the period of daylight saving, but one percent per day of daylight saving. Another more recent study by DOT (U.S. Department of Transportation) in 2005 has shown that “the total electricity savings associated with DST (daylight saving time) amounted to about 1 percent in spring and fall, corresponding to national savings of forty to fifty megawatt hours per day.” (Source C) Now although this number is much more significant, there is a

Keoni (2014) writes that there was a decline in poverty by approximately one-third in 1967. In addition, the population in poorness decreased 25.8% in 1967 and 16.0% in 2012. Even though that war against poverty saw outstanding progress, there are still tasks yet to be accomplished. Most poor citizens moved from poverty after waiting for years. According to Keoni (2014) in 2012, 45 million citizens moved out of poverty.
