In information systems, a tag is a keyword or term assigned to a piece of information (such as an Internet bookmark, digital image, database record, or computer file). This kind of metadata helps describe an item and allows it to be found again by browsing or searching. Tags are generally chosen informally and personally by the item's creator or by its viewer, depending on the system, although they may also be chosen from a controlled vocabulary.Tagging was popularized by websites associated with Web 2.0 and is an important feature of many Web 2.0 services. It is now also part of other database systems, desktop applications, and operating systems.
Say I have a dozen of strings like this, with different content between the bold markup tags ("Re:" is also a constant). I need a regular expression that will match this. Basic and I think I am close, but just need a little help.
Here is what I have, but it's not matching
(?<=)Re:.*?(?=]) or...
Summary: Unable to view equations in proper format
Hi
I am unable to view equations in proper format even after using latex tags shown in help.
For example :
\xi = x - vt

Again
\frac {\partial x} {\partial y} =

Please help
TIA
I'm afraid my Google-fu is failing me. Try as I might, I can only find very basic descriptions online of how RFID tags (specifically passive ones) work. I'd like to actually know what the microcontroller in the tag does, and how it creates a signal the reader can pick up and decode. For example...
Some of my songs are not taged correctly , so I wanted to change their tags on my pc . I remember I could've edit the tags in nokia e75 and I had managed to sort my music library more easily . So , I want to ask as if there's any way that I can change the tags of a song ?
I'm up late despite having a final tomorrow, and the only thing I've accomplished is noticing that this one and a half decade old forum doesn't have a gif thread.
The rules:
1)Forum Rules apply. Keep it PG.
2)Use spoiler tags so people don't run their data up.
3)Don't just post stuff from the...
Hi!
My name is Joseph, I'm studying mechatronics technology. I just started my first physics course, and I've realized that my whole life, intuition, and "understanding" of the things around me is a fat LIE! I know NOOOOOOTHING! This is tremendously frustrating for me, and so I have decide to...
I noticed that the LaTeX in one of my old posts is messed up. The problems start with this piece:
##C:(a,b)\to \mathbb R^4##
The result should look like this:
##C:(a,b)\to \mathbb R^4##
But instead it looks like this:
##C:(a,b)\to \mathbb R^4##.
Actually it's even worse. The 4 is on a new...
Hi,
I am designing an ASK demodulator for RFID Tags. I have attached the circuit diagram. This is the ckt from IEEE paper.
If you look at the ckt, the first stage is the inverter kind of thing. I didn't get why second NMOS is used for Stage I. Similarly, the second stage is also inverter...
Hi,
I have been searching and looking for RFID tags that capture moisture and temperature but i didn't find specific things. Could anybody provide some references or models names please?
I am trying to use Sow/Reap in Mathematica to replace Append in my code. The problem is that I need to define the tags within my code, but doing so doesn't reap the desired results. A simplified version of my code is
Clear[tag];
Reap[tag = {a,b}; Sow[1, a];Sow[2,b];, tag]
However, if I...
suppose Team Red wants to make RFID tags that only their own "authorized" scanners can pick up, such as for tagging merchandise in Walmart. Meanwhile Team Blue wants to be able to find any Team Red tags on items or prove that they are not there. They don't need to extract any info from the tags...
Like whenever you are buying anything and you want to see the price, it isn't there. Which is weird because another item beside it has a price tag.
Like did someone just went up there and remove the price tag and then hide it somewhere else? I am sure whoever was stocking must have notice...
Good day, I have been given the task to create an inventory database for the books at the library at my school using the RFID to monitor the books. However the books have specific codes based on their type and location in the library. I was wondering if someone could give me some information as...
I know that there's probably a way to do this with regexp, but I don't know regexp (yet). So does anyone have any tips on how to create the regexp expression for it? (and what other ways are there?)
Does anyone know of any LaTeX modules that makes the pdf output generated by pdflatex ADA/Section 508 compliant?
Same question regarding graphviz plug-ins?
hi,
i need help... i am planing to design a small location detection system within a room using RFID tags or some resonace technique. Each object must have a unique identification code. I intend to place 4 detectors like Satellites to determine the exact position of the object... I need...
Hi.
We are developing a system of RF tags for open space storage place. This are mostly containers. I need to make simulation of collisions in simultaneous Tag's transmission. Let's say I need 10 Tags to send update to base stations at exactly the same time. The idea to connect tags with wires...
Does anyone know where I can purchase an RFID reader and some RFID tags please? I'm doing my thesis on this technology and I need to buy some of these. Testing purposes.
I'm sorry but I can't seem to figure out how to tag LATEX in my posts so that my equations in my posts come out in LATEX. What are the wrap tags for LaTeX on here. Is there a help section somewhere for these types of technical questions.
