Calculating Stride Length & Stride Frequency

[ad_1]

The following exercise explains how you can calculate the stride length and stride frequency of a runner on a treadmill.

Consider first some definitions of terms:

Stride length: Stride Length corresponds to the horizontal distance between the location of a foot at one point in time (usually the first point of contact with the ground)to the same point of the same foot at the next occurrence of the selected position in the running cycle.

Step: A step corresponds to the horizontal distance between the location of a foot at one point in time (usually the first point of contact with the ground) to the same point of the contra-lateral foot at the next occurrence of the selected position in the running cycle. In essence two steps constitute a stride.

Stride Frequency: Stride frequency corresponds to the number of strides that are completed in a specified time period. The standard unit of measurement is the hertz (Hz) which records the number of cycles per second. Step frequency is the equivalent measure using a step (as defined above) as the core parameter.

Timecode: Time code records the passage of time via the use of a sequence of pairs of numbers separated by colons. e.g. 00:01:15:32. The first pair of numbers represents the number of hours, the second pair the number of minutes, the third pair the number of seconds and the last pair the number of hundredths of a second.

The speed of a runner can be defined as being equal to Stride Length × Stride Frequency

Given the relationship between running velocity, stride length and stride frequency plus a video record (with timecode) of a runner on a treadmill it is a straight forward matter to calculate values for the stride length and stride frequency of a runner at a known speed.

How to Win at Online Slots Games

[ad_1]

Being a winning slot machine player is impossible. All slot machines are specifically designed in order to give the house a long term edge, so the house will always come out ahead if you play long enough. The only real way to counteract the house edge on slot machine games is to play a game with a really big jackpot, bet the max every time you play, and hope that you hit the jackpot. Then when you do hit the really big jackpot, guess what you do next? Stop playing that game.

Don’t get me wrong. I’m not saying that you shouldn’t play slot machines. In fact, I think slot games, especially the really good ones, are a lot of fun. But you want to keep in the forefront of your mind that mathematically, what you’re doing when you’re playing a slot machine on a long term basis is paying for entertainment. You can calculate how much you’re paying for that entertainment by multiplying the house edge times your average bet times your number of spins per hour.

For example, if you’re playing a slot game with a payout of 95%, then the house edge is 5%. (The casino keeps 5% of every bet you make long term.) And if you’re average bet is $3, then you’re going to pay an average of 15 cents per spin to the house. (5% times $3.) Assuming you’re making 500 spins per hour, that game costs you $75/hour to play, which may or may not be a reasonable price for you entertainment. That depends on your bankroll.

Something else to factor into your calculation is how much the perks and bonuses you’re getting back from the casino are worth. If you’re playing in a land-based casino where you’re getting free drinks while you play, then you can subtract the cost of those drinks from you’re hourly cost. (Or you can add the cost of those drinks to the value of the entertainment you’re receiving–it’s just a matter of perspective.) My recommendation is to drink top-shelf liquor and premium beers in order to maximize the entertainment value you’re receiving. A Heineken can cost $4 a bottle in a nice restaurant. Drink two Heinekens an hour, and you’ve just lowered what it costs you to play each hour from $75 to $68.

Slot clubs also give back a percentage of your losses each hour, so definitely be sure you join the casino’s slot club and ALWAYS use your card to track your play. There’s absolutely no reason not to do this. Casinos also reward their larger slot players with comps like meals, show tickets, and free rooms, which all add up to reduce the amount of money you’re spending each hour that you’re playing on their machine.

So how to be a winning slot machine player? I’d sum it up by saying know how much it’s costing you to play each spin and each hour, take advantage of all the comps and the perks, and go for the big progressive jackpot.

Does Karate Really Help Longevity? Why Does Data Not Support It Across 118 Masters

[ad_1]

There has now been a study done on the issue of longevity across karate styles in concert with data crunching by a University of South Australia academic. It was done as karate is perceived by practitioners as lifespan extending, however the sport and art is unique in a number of ways given its injury rate, life-long stresses and training culture. So given that the vast majority of karate-ka that have been polled over the years believe that the art fosters a long life, highlighting the stereotype of a ‘Yoda’ like old and wise master, it was worth re-visiting as this may not in fact be the reality.

The study involved:

– multiple doctors spanning medical research, clinicians a psychologist & karate practitioners

– data that shows that lifelong karate practice in different styles has different effects on lifespan, including:

– regional effects (East, West, post WWII until today & comparisons to karate-ka born in the 1800s)

– differing types of inflammation and how it possibly ties to karate longevity

– sparring, drills, ude tanren and kata like sanchin how do each of them really impact longevity

– dojo cultural considerations

– the effect of the developed karate persona & combative environments on longevity

In particular the data shows that all karate styles’ masters, on average, die young since WWII. However the exploration of the many variables and links to style types as well as noting some differences is key (and evidence based practice approach by region, style and era). For example, the data for the masters who lived in the 1800s is somewhat unique, and attributes of training today provides possibilities as to why that it is the case. Data spanned 118 karate masters (8th dans, style founders, style successors etc.) to analyse the links to shortened lifespan in karate styles and factored in: injury rates, diets in regions, psychology and combative factors and stance/practice types.

In some ways the general idea of this existed in the 1800s despite today’s almost universal spin that martial arts results in long-term health as a core theme. Supporting this are some interesting statements on the topic by passed masters such as Itosu of the 1800s, Shito-ryu’s Mabuni, Asai of Shotokan who openly stated health may not go hand-in-hand with budo.

Understanding the pluses and minuses for certain ways of doing karate inside all of the styles from Shotokan, Goju to Shito-ryu, is key for many who have health as a central theme.

Social Media Defining CRM Landscape

[ad_1]

With enhanced participation of marketing through the social media platforms, there has been an increase in technology related spending by marketing departments in an organization. A large part of this has to do with implementing customer relationship management (CRM) systems that incorporate various social media platforms for marketing communication. This can be termed as Social CRM.

Small business and start-ups with limited technology budgets have greatly benefitted from this. Social CRM is now being actively implemented by all organizations, big or small. It is being used to incorporate marketing strategies that are the best, current, affordable, and prone to limited errors. This is a paradigm shift from the regular CRM systems (with a series of errors) that have been implemented so far.

Traditional CRM

The traditional CRM system has made a tremendous contribution to businesses in its own way. It has assisted in managing and developing customer relationships, lowering cost, enhancing profitability, offering tailor-made customized product and service offerings, handling customer complaints, queries, and applying analytics to customer data for creating a win-win situation for businesses and customers. However, there have been drawbacks too.

The above mentioned benefits pertain to an accurately implemented CRM strategy. A poorly implemented CRM program is one that aims to manoeuvre customer thoughts by being overtly personal. Another example is a CRM that aims to reduce operating costs by limiting human connect and replaces a human with an answering machine who never really solves a complaint. Cases where user analytics on buying behavior (in case of an e-commerce website) are incorrectly applied to make inappropriate suggestions to customers, or have a high level of promotional activity aimed at customer conversion, have instead of managing a relationship with customers actually annoyed them to the level of even severing a relationship.

Changed Dimension of CRM

Today, customers demand a relationship that is slow paced, insightful, and responsive. Customers appreciate a relationship that develops over time and is based on trust. Information analytics should be used wisely. Focussing too much on what the customer bought prevents concentration on the actual needs for making the purchase. Treating a customer as a data source prevents a marketer from being empathetic, responsive and perceptive of a customer’s actual requirements – the very issue with a traditionally executed CRM.

Social CRM is a complementary addition to traditional CRM packages. More than 74 percent of online American adults are using social networking websites (as per Pew Internet Project’s research as of Jan, 2014) to exchange views on brands, customer service, and personal experiences with businesses. Thus, there has been an increase in power for the hands of consumers in regard to the business. The coverage and power of social media has added a special element to CRM which not only covers the customers but also the companies.

Two-Way Communications

How can businesses leverage this enhanced presence of social media to their advantage? The answer is: by relying on the power of two-way, healthy communication that involves the customer and the company. Communication is more of listening than talking. Listen to your customers more and respond gently instead of solely focussing on pitching. Making use of Social CRM tools can open the gates of two-way communication. The faster an organization incorporates social CRM tools to its existing CRM strategy, the more effective its customer relationship strategy will become.

Conclusion

With a changed landscape in CRM with enhanced reach and scope of social media as a platform to communicate across markets, time zones, and country borders, CRM cannot remain single sided. Companies can manage their relationship with current, new, and even untapped customers through the powerful social CRM tools. CRM can enhance the level of trust and focus on effective brand building strategies in the market. The fine balance of relationship can be restored and re-invented through social CRM. Businesses that are proactive understand that if they concentrate on the equilibrium of relationships, customers practically manage themselves.

Roach Repellent – 5 Ways To Keep Cockroaches Out Of Your Home

[ad_1]

Repelling cockroaches is one portion of an integrated pest management solution for ridding your home of cockroach infestations. If the roaches don’t like the environment of your home, they are less likely to enter and nest in the first place. If you can find roach repellents that don’t also repel all the humans you know – even better.

The following 5 roach repellents might just do the trick to make your home the last place a roach wants to live:

Pepper Spray – Roaches don’t like red pepper. So, if you spray surfaces in your kitchen and bath with a solution containing red pepper, the will avoid those surfaces. An easy recipe to whip up a batch of spray is to mix 2 tablespoons of Tobasco Sauce (the primary ingredients are red pepper and vinegar) with 1 quart of water. Pour it into a pump spray bottle and mist it onto surfaces. A word of caution, you will be misting pepper spray into the air. Until the mist settles, you are likely to sneeze more than a few times. Consider wearing a mask when you apply the spray.

Moth Balls – Roaches, like moths, don’t like the smell of moth balls. One common remedy is to drop a couple moth balls behind the stove to keep the bugs from hanging out back there. One or two in the cabinet under the sink can be helpful as well. Moth balls are not good for humans, so don’t place them near food or food prep areas.

Cedar Products – The oils in cedar wood are an effective natural deterrent for a host of bugs. There are many products available to take advantage of this fact. Look for thin cedar veneers that can be used to line drawers and cabinets, cedar balls, blocks, chips, etc to place in drawers and closets, and (of course) cedar boards and paneling to line closet walls for the ultimate protection.

Mint Oil – Mint oil is a primary ingredient in several non-toxic roach sprays. The roaches avoid it, and when coated with it, they suffocate. The sprays don’t kill as fast as typical poisons, but they are safe to use in the kitchen and around pets and children. It is possible to create a spray, like the pepper spray, by diluting some Dr. Brauner’s Peppermint Castile Soap in water and then applying with a spray bottle. I haven’t tried it, but you might be able to create your own roach spray this way if the soap concentration is high enough.

Bay Leaves – Bay leaves are another sent that roaches avoid. You can pick up a bunch of dry bay leaves in the spice section of any grocery. Place whole leaves or small sachets of crushed leaves in closets and cabinets. This is a good option for kitchen cupboards.

With the exception of moth balls, there are no hazardous chemicals in any of these roach repellents. Give them a try, in combination with baiting, sealing, and applications of diatomaceous earth and boric acid to eliminate roaches from your home.

Tips For Using a DVD VHS Combo Player

[ad_1]

If you enjoy watching movies on your DVD player but still have movies and other events that you purchased or taped on VHS cassettes, a DVD VHS combo player will solve all your problems. There will no longer be a need to have two separate players so you will be saving space and simplifying the process of hooking up two different devices to your television set. Actually, some people have a TV that only offers ports for one device so if you are one of those people, you can now enjoy the pleasures of DVD and VHS playing. There will be no more double the messy wires to contend with, and with only one player most of the wires can be hidden behind your DVD VHS combo player.

You will also save money with having to only purchase one device. The advances in technology continue to simplify life for the consumer – both financially and in terms of ease of use and space.

There are some tips for ensuring that you get the best quality combo that will give you all the features you are looking for including versatility. When it comes to Signal to Noise Ratio this will determine the quality of the audio sound. You will have better sound quality if the decibel rating is higher. DAC stands for Digital to Analog Conversion. This is important for playing your DVDs as it converts the digital signal to an analog signal that the TV will be able to use. Therefore, you will want a good DAC rating. Front Panel Inputs save you the trouble of reaching around to the back of the device to plug in other media or devices. Input/Output is the type of DVD and analog signals that your DVD VHS combo player can read and transmit to the television.

The Panasonic DMR-EZ48VK DVD VHS combo player offers superb recording and playback of both DVD and VHS tapes. This player will easily transfer VHS taped material to DVD with just the push of two buttons – it does not get much easier than that. Copying from DVD to VHS is very simple as well, although that is probably something that most people will not need to do. The combo comes with four recording modes for DVDs. The XP setting is considered the best quality and it will record an hour of content; the SP mode will record for two hours and users seem to feel that they see no difference in the quality of the two modes. Four hours can be recorded in the LP setting and eight hours can be recorded in the EP setting, but quality does suffer in these modes. VHS tapes can be recorded at three different speeds: SP, EP and VP with SP being the best.

There are other great DVD VHS combo players available, for example, there is the Sony RDR-VX560, the JVC DR-MV150B, the Toshiba DVR670 and the Samsung DVD-VR375A to name a few. It would be wise to do an online comparison of these combos to ensure that the DVD VHS combo player you purchase will give you all the features you are looking for in this device that will definitely double your entertainment pleasure!

Female Orgasms – How To Give Your Woman An ANAL ORGASM That Makes Her Addicted To Butt Sex

[ad_1]

When it comes to female orgasms, most men only know about clitoral orgasms, some know about vaginal orgasms and squirting orgasms — but very few know how to give their women anal orgasms.

Heck, very few men (and women) even know that anal orgasms are possible.

But here’s the thing…

Anal orgasms are not only possible, they are one of the most POWERFUL types of orgasm a woman can have and in this article you are going to discover how to give your woman an anal orgasm so intense and sexually pleasurable — it makes her addicted to butt sex.

Does that sound too good to be true?

I can understand if you answered “YES” to that question.

However, if you read on with an open mind and use what you read with your woman… you will increase the quality of your love-making sessions in a way that words can not do justice.

Just before we get into the sexual technique that will let you to give your woman an anal orgasm, here are:

3 Rules For Successful Anal Play

1. Start Out Very Slowly

Quite simply — if you don’t and you end up doing something that hurts your woman, she will probably stop you from ever touching her anus again.

So always be cautious with anal play and start out slowly.

2. Use Lots Of Lubrication

This one is self-explanatory.

3. Never Put Anything That’s Been In Your Woman’s Ass Back In Her Vagina

Sticking to this rule will prevent any vaginal infections.

Now, let’s get into the fun stuff…

Female Orgasms – How To Give Your Woman An Anal Orgasm That Makes Her Addicted To Butt Sex

Start off by having some FOREPLAY with your woman and getting her very sexually aroused.

I then recommend that you give her a clitoral orgasm and at least one ‘deep spot’ orgasm because this will put her in an orgasmic state, where she’ll be expecting even more pleasure.

Next, make sure that your woman is laying on her back with her legs open and put your middle finger into her anus with your palm facing upwards.

At this point you need to understand that the wall that separates your woman’s vagina and anus is very thin. With that in mind, you are going to stimulate your woman’s G-Spot with the finger that is in her ass.

If you push upwards you will be able to feel her G-Spot through the wall that separates her anus and vagina. Once you find it — rub it backwards and forwards until you give her an ANAL ORGASM.

This is so powerful.

Once you give your woman an anal orgasm like this, expect her to beg you to ‘take her ass’ with your ‘tool’ very soon.

99% of men don’t know about this, so use it wisely and be sure to give your woman incredible pleasure.

CCTV Cameras Guide

[ad_1]

If you have ever walked into a place of business and seen the little cameras that hang around the room, aimed at entries, exits, and cash registers, then you already are familiar with the term security camera. But do you know these cameras are actually called CCTV cameras and they are used primarily for surveillance and security purposes.

Does it sound a little creepy to you to know you are being watched? You can relax because it is not like you are being stalked or spied on for the day. The cameras are strictly used for monitoring doorways for watching would be intruders, thieves, or attackers. It is re assuring to know that if someone has entered the building in hopes of robbing the cash register or kidnapping a child that the CCTV cameras will capture and record the face of the perpetrator and hopefully lead to their arrest.

While security cameras cannot prevent a crime, they can catch the theft in action that eventually will help police find the intruder. This is nice to know, especially when stolen children are involved.

Many kidnappers and thieves know they are being watched through the cameras. Businesses have wised up to this, also, and have learned how to combat the allusions from the intruders. The result of this new knowledge was hidden cameras. Now security cameras can be placed in everything, in anything, and in every place. The CCTV cameras are so small and tiny, you never know where they may be lurking. Bad for the intruder, good for the business! This offers a peace of mind to a business owner who is tired of their merchandise disappearing for free. It is no surprise that companies want this added protection.

There are some cameras that can transmit the data straight to the computer while some systems place the data onto a screen like TV. These cameras are used in places like malls, bigger sized business complexes and most government installations. CCTV cameras are installed in all kinds of places where you would never imagine them to be but you can rest assured that professional businesses and companies are not using them in a bad way. They are merely for monitoring the safety of businesses, children, and anti-theft purposes. They are used for good things and are needed in the public places. They have been used successfully to track down burglars, intruders, bank robbers, and kidnappers, among other things as well.
