Life times of one brand of light bulb were observed. Life hours of nine light bulbs were 898, 720, 354, 405, 620, 54, 229, 306, 890. There were three more light bulbs that were still burning after 1000 hours. It is common to assume the life time of a light bulb follows an exponential distribution. With the observed data find the MLE of...

I plugged a single lamp into it, with a 60W bulb. At 3:40p I pulled the power.

Is the battery old? PbAc ones usually last for 2-3 years and then degrade. Should be a field-replaceable part. Some 20 years ago I had an APC BackUPS become a glorified power strip every few years, so when the wall power disappeared - load went down immediately. It was also beeping about battery replacement (but in the closet, was not often noticed quickly). This is also a way for you to check if

...derately sized sets of time series data. FYI - I'm using the following versions of R and supporting packages on a Windows 2000 OS: - R version 2.4.1 (2006-12-18) - zoo version 1.2-2 - chron version 2.3-10 The two time series I'm working with are from the summer of 2004 and are: 1.) wet.bulb.air.temp: air temperatures recorded on an hourly basis, and 2.) creek.temperature: surface water body temperatures collected every 12 minutes. I would ultimately like to observe the difference in temperatures and attempted to get at this by merging the two time series (by union), interpolating th...

I crashed my car and need the entire turn indicator assembly. Drivers side. Can anybody help. No local retailers have it. I did get a wiring tube but still need the seal, bulb holder and gasket. Thank you, Susan -- Susan Slayter King (949) 391-0914

Hello everyone- I was just reading the article on Rails at O''Reilly and one of those little light bulbs over my head went off - what a GREAT tool. I tried to install both Ruby on my Mac PowerBook without much luck and then tried to install Ruby and Rails on a FreeBSD server I have. I am running into some odd errors - so, my question is - can you point me to some tech resources for either of...

....battery.start test.battery.start.deep Both appear to leave the battery voltage at line-power levels; while the quick test does have a notable voltage delta. Are there any other tests I can perform or ways that I can help gather data to get the longer tests supported? I borrowed a 60W light bulb (instead of one of the new weird ones that stores are now selling to drive people to just try an LED light). For the 1100W/2200 VA 5E model a 60W light registers as a ups.load of ~2 (clearly truncated; I guess this correlates to approximately floor((100 * 60)/2200)) It took me a while to remember...

A little off topic but.... I need to put a 24 port Gig PoE switch into a small office - no computer room / rack etc. All CAT5 terminates near the owners desk (smart huh?). I want to put a PoE switch in place, with 24 ports and Gig speed. Everyone I've researched so far is LOUD... Anyone know of a quiet one?

Hi! Sorry for asking a trivial questions, but I can't seem to figure this out. I have a dataframe called master containing 30-odd variables. In this dataframe, I have observations across these 30 variables from 1930 to 2003 (I've made a "year" variable). How can I drop all rows for which the year is less than 1960? I'm assuming something with ifelse() but I can't

Hi I hope someone can please help. I have an Ubuntu Server running 14.04.3 LTS and using an APC ES550 UPS connected via USB. I've installed Nut and can see it does monitor the UPS correctly and give the correct stats with battery percentage etc. But on doing a "real" test and unplugging the UPS from the power supply, after watching the battery drop slowly suddenly the server just

The only relevant test is under real load, which is why I suggested using a small motor or a light bulb. > I have no other ways to test the battery themselves, I'm not quite > electricity-tech to make some hackish testing (and dangerous). It's your choice but unless you short circuit the terminals which you should not do with ANY battery, there is no danger. It's as dangerous a...

...ars in archives, first disconnect batteries & check voltage of each battery, - dead easy, Then much more important: calculate internal resistance of each battery. Batteries go bad after some years, even on trickle charge. Measure voltage drop when driving a load such as 1 or a few car headlamp bulbs in parallel. Then its simply Ohms law V=IR, If voltage drops from say 13V to 11V & if you use 1 headlamp that uses maybe 4 amps, then 13-11 / 4 = 2/4 = 0.5 which is on high side, you dont want higher, better 0.3 or less. Your UPS for PC's will prob. want a lot more than 4 amps, so low i...

...my view is there is less electronic wear and tear when powered up 24/7 and due to inrush power surge on power up, less chance of some component going bad. years back when i did computer systems work, i had a couple client calls for a system not powering up at start of morning hours. i used light bulb example to explain why and that they would naturally see an increase in utilities bill. both started leaving systems up. have a friend who's system lost power supply on power up, and again, after explaining about light bulb, he leaves system powered up and because he is using centos and kde, h...
