AtricleZine - A Optimal And Result Prone Testbed For Studies Of Ad-Hoc Network Behaviour
The first three-year chart shows NYMO and NYSI are in intermediate-term downtrends. Normally, when the NYMO 50-day MA (red line) reaches negative 20 or lower, SPX bottoms. Currently, the NYMO 50-day MA is roughly zero. Also, when the daily NYSI reaches roughly negative 500, SPX bottoms. Currently, NYSI is above 660.The second three-year chart shows the CPC 200-day MA (red line) continues to reach all-time highs, which is SPX bullish, since the CBOE Put/Call is a contrarian indicator. Also, remarkably, the CPC 50-day MA (blue line) is currently near its all-time high set in Jul, before SPX rose over 200 points.The conflicting signals suggest a period of higher volatility. VIX (in second chart) fell to and traded around 10 over the Jul to Feb SPX rally. Currently, VIX is about 15 and may trade in a higher an
Most of us are all too familiar with what a 401k plan is. Usually within the first few days of starting a new job someone from human resources sits down with you to explain your benefits package. The 401k retirement plan is a huge part of that conversation. If you are 45 years old or younger, you may not even remember a time when there was no 401k retirement plan.Would you believe that the 401k plan was birthed in 1978? It was named after a provision in the Revenue Act of 1978 that was titled, Internal Revenue Code (IRC) Sec. 401(k). This code became law and went into effect on January 1, 1980. Prior to that, companies offered pension plans. These were typically steady income payments made in the form of a guaranteed annuity to a retired or disabled employee.In 1979 several companies began the process of a
For example, in NS-2 the standard way to model node delays is by using a timer and performing some actions on the expiration of the timer. In our testbed, the capabilities of the hardware are limited and therefore tasks such as packet processing requires much more time than in traditional routers. Real world experiments inherently include these increased processing costs. For these reasons, we decided to build a testbed using fully-understood hard- and software that allows to perform measurements and to evaluate scenarios covering all layers beginning at the radio-layer and embracing all layers up to HTTP/TCP/IP and the application space. The hardware is an embedded device we call Embedded Wireless Module (EWM) consisting of a core controller (Motorola 68HC912) and I/O peripherals as well as different wireless and wired network connectors. The device is, for example, equipped with Bluetooth and a 433 MHz RF module. In this paper, we demonstrate some experiments we have performed with this hardware. We present some general observations as well as some real world experiments covering different application domains such as ad-hoc gaming and home automation. While vertical handover times between Bluetooth and the 433 MHz RF modules are in the order of milliseconds, our m
So you’ve decided to hang out your shingle and start your own bookkeeping business. Now the nail-biting begins. How are you going to line up some clients fast?1. Send out a sales letter to new businesses announcing your bookkeeping service. Put together a mailing list using your local Yellow Pages directory or Chamber of Commerce membership list.2. Place a display ad in your local newspaper. Watch your costs on this though, as display ads can really be expensive. You could create a “Question and Answer” display ad which solves a common problem a potential customer may have. Your expertise will help assure potential clients that you know your stuff. Create a different ad weekly and you could develop a loyal following.3. Place a classified ad in the Work Wanted section. Make sure you create a

When you hear the word “marketing” what comes to mind? More business or wasted money? If your experience with marketing or advertising has been less than positive your cynicism may be well founded. Yet, have you ever noticed a competitor with a mediocre product and a healthy business? The difference is often marketing.Some say they’ve never done marketing and don’t need to because of good word- of-mouth. Positive word-of-mouth is great, but not enough if you’re serious about growing your business. Others do invest in marketing yet treat it as a necessary evil. The problem with that mindset is that it’s driving with the brakes on. Those people sabotage their efforts by making poor decisions, taking half-measures and often resisting anything innovative.When asked about the “one big key” to marketing
Let’s face it: we all remember our first home computer--it wasn’t that long ago. My dad brought home one of his old computers from work; the screen was approximately 8 x 8 inches, and it was certainly not the flat screens we see today. Behind the screen, I’m certain there were mice running in wheels—there was definitely enough space for them and the speed of that computer was slower than it takes to make Thanksgiving dinner. We used it initially as a word processor and could never imagine that our computer would change so much in the next 15 years.Now think back to your first cell phone. Mine was shaped like (and probably weighed as much as) a brick. It did not fold, the antenna had to be extended to even dream about hearing the other person who was calling, it was used only for emergencies and the rates of
Once you have your web site complete and ready to be listed you need to take a slow step by step approach to get listed in the search engines. If you do it right the first time and then build on that formula, your profits and your site will benefit in the long run. Those willing to spend the time and put these techniques into practice are the ones that will benefit and are more likely to be successful.1. Your first page is where search engines will start and making sure that this page is fully optimized is one of your first goals. What's optimization your ask? It's making your site as search engine friendly as possible. You will also see people refer to this in the short form of SEO.Your first step is the TITLE TAG. This is one item that search engines look for to start getting information about what your
The presented home automation scenario evaluates the efficiency of service usage in ad-hoc networks. While demonstrating the feasibility of this approach further optimizations of some of the steps are necessary. The remainder of this paper is outlined as follows: In the next section, we describe the hard- and software of this testbed. In Section 3, we discuss general observations found in our experiments and in Section 4 we present selected experiments. Finally we compare with related work and discuss the overall conclusions.
Gaming case
In this scenario, we describe our experiences with an infrastructure for ad-hoc multiplayer games that uses EWM modules as the main components. Our goal is to develop an architecture that supports ad-hoc multi-user games on mobile devices such as PDAs and mobile telephones. The architecture should require a small and cheap infrastructure only and it should be possible to set up the infrastructure very quickly and in an ad-hoc fashion. We envision for example a place like a university, a subway station and other places where people meet and possibly wait for transportation, the beginning of a lecture etc. In these scenarios, spontaneous group formation will take place if it is supported by some technical means. For example, the system could provide high-scores, a gamer’s archive allowing pers
