Shit the admins say during DE in Singapore

Diamond Edge in SG was 2 weeks ago but we admins finally got ourselves together to watch our fancams/listen to the audio we recorded, and we noticed that we do say a lot of rubbish, so here’s a list of the nonsense we said during the concert!

Just a quick background: Admin Hoshit and Jihooned were sitting together and Admin Wooed and Scooped were sitting together!

Our hi-touch and Diamond Edge confessions

WARNING: LONG POST AHEAD (also setlist may not be accurate)

**please excuse our singlish

PRECONCERT

Jihooned: I’ll hold the Joshua banner cause it won’t break

Hoshit: “what if my bong runs out of batteries and i gotta change during a song lmao wouldn’t that be funny” (HAH FORESHADOWING HAH)

Jihooned: our bongs damn noisy

/Jihoon and Hoshit could not decide between their biases and so chose to buy multiple straps/ the clanking of the bong bongs can be heard all the way from VIP to cat 4

Jun sexily walks up

Scooped & Wooed: “eh who that” “idk” “can’t see leh”

“OH FK” “ITS JUN OMGGG KJDFHALKSJDFHK”

Hoshit and Jihooned: “who’s that ah cannot see”

Jihooned: “is that wonwoo?”

Hoshit and jihooned after realising it’s Jun: “omg jun jun juN jUN JUN JUN JUN JUN”

Junnie: RIP, Birth - 29 Sept 2017 8:12PM. “Jun is beautiful.”

PRETTY U

Jihooned: “SEOKMINNNNNNNNNNN”

Hoshit: “SEVENTEEN SARANGHAE YEPPEUDA”

HEALING

Junnie: OH SHIZZZ LOOK AT JUN CARRYING JOSHUA??? THAT’S SO FLUFFY OMFG MY LIFE IS COMPLETE.

Hoshit; notices that they are spraying water: “I WANT THE HOLY WATER I WAN- GODDAMIT SEVENTEEN TRAIN YOUR ARMS HOW CAN YOU ONLY SPLASH WATER 1 METRE AWAY WHAT KIND OF PUNY PEOPL- JIHOON IS CHASING CHAN GO MY BOY BE FREE”

Ending Ment

/When jihoon finishes talking/

Jihooned: Wts is he high on drugs or something

Hoshit: “i love seventeen”, she says, as tears stream down her face

Junnie teared up here when she heard Jun & Jisoo’s ment. But she couldn’t say anything because all the other admins were sitting far away. All she could do was try not to draw attention to herself.

END OF CONCERT

Hoshit: HOW DO I STOP STREAMING THIS AUDIO

Jihooned: Eh we still got hi touch

Hoshit: oh my God i want to die but i have to wait until after the hi touch

Junnie actually teared up again (what the actual heck) because she remembered Jun & Jisoo’s ment. (Ya’ll have to know, Junnie doesn’t cry often So this was a magical and emotional moment for her.)

Wooed & Scooped just sighed and hugged each other with happiness and feels everywhere

Aaaaaaa thank you for reading through this super long post full of our nonsense and don't worry, our hi touch experience + confessions will be revealed in another post one day~~

Shear Force Measured Under Patient's Hip on an I Inclined Bed-Juniper Publishers

Abstract

Shear force is measured under a patient's hip when he is on an inclined bed. To do that, we need to develop an instrument. That means to find a sensor and because it is expected that the shear force is very weak the signal must be amplified so we have to design an amplify, certainly we need a read out unit to indicate the measurement. All these are given in detail in this paper. Through theoretical consideration for a simplified model, a functional relationship between the shear force and the inclined angle of the bed is also obtained. To make it clear the explanation of friction, shear force and shear stress is given in Appendix

Editorial

Patients occasionally required to be on an inclined bed for certain therapy. One easily understandable therapy is to help the blood circulation in the legs and feet. When a patient stays long in a horizontal bed, often will have a muscle clamp in the legs. If the bed can be adjusted to an inclined position the clamp can be stopped. The shear force between his hip and the bed affects strongly how long the patient can stay at that position and is expected to be a function of inclined angle. Shear force is a familiar terminology for mechanical engineers, but it may be not clear to layman outside engineering so a detail explanation is attached in Appendix. Certainly it is good to know exactly the force and the inclined angle how they are correlated. Our project is simply to find that relationship.

There are many different possibilities for the measurement. Search through the literature, we found that the closest paper is done by RHM Goossens, it is entitled "Shear Stress Measured on Three Different Cushioning Materials” [1]. This paper describes the shear stress measured at the patient's hip sitting on an inclined chair for different cushion materials at three different seat angles, 5° forward 5° backward and horizontal. Six sensors were used, but there is no detail about the sensors except the size. The measured results were about 4-7KPa for the shear stress. This is not exactly what we need, however it shows the stress is in very low value and sensors must be thin. Further search we find "Load Cell Assembly” by Kroll et al. [2]. This is a Patient application. It describes the shear stress measured by strain gages. From here we feel that strain gage may be a good candidate for our measurement. Another paper entitled "Plantar Shear Stress Measurements” by Rajalal, Lekkala [3] is a review paper, confirms that strain gage may be used for shear stress measurement.

Our Approach

Since the shear force is based on the friction of patient's hip on an inclined bed, it must be very small or say, it is expected to be a fraction of a kilogram of force. So we choose strain gages to be the sensor, and they are mounted on a piece of rubber with the shape showed in Figure 1. It is known that strain gages are not to be mounted on rubber, it will not stay long. But because other materials will not produce the strain to cause the sensor to react we do not have other choice. The shape is specially designed in this way so that is strain is more in the webs where the strain gages are mounted. Two strain gages are connected in series so it will be more sensitive. This piece of rubber is mounted between two pieces of stainless steel sheet, the top edge is attached to the bottom plate and the bottom edge is attached to the top plate. The stainless steel plates are loosely connected by a screw in the middle so that two plates can be easily moved by the shear force. The whole sensor assembly is 15.24 X 30.48 X 0.476 cm. It is thin enough; it can be buried in the blanket of the bed. The picture of the whole assembly is shown in Figure 2.

Since the shear force is low, the signal in the strain gages is weak; in order to have readable output we must have a good amplifier. A differential amplifier with IC AD706 is chosen for our circuit. The constant current to the strain gages is supplied through an NPN transistor 2N2222. If the whole signal of the strain gage is sent directly to the amplifier, the output will be very high even the amplifier with the limited gain. To solve this problem we build a compensation circuit to balance the dc voltage output from the strain gages. In this way only the increased voltage in the strain gages will be amplified. High gain of 50 is chosen for the amplifier. Because this instrument will not be used constantly, the part for dc voltage measurement in a multi meter is used for the readout unit. The advantage of using a multi meter is that its' sensitivity is automatically built in, the most sensitive position is 0.6 v, next is 3.0v and then 12v. We can easily ship the sensitivity when the output changes. To make the reading stable near the zero, another compensation circuit is built for the zero point adjustment. The whole circuit is shown in Figure 3. The power is supplied from an adjustable voltage AC power supply and rectified by a full wave bridge circuit with a complete filter. The voltage at the input is 11 volts.

The instrument is tested to make it certain that the performance is sensitive and stable. Then we calibrate the instrument. A spring scale is used for the indication of the input force. The calibration results are given in Figure 4.

Analysis

The analysis done in the following is much simplified from the actual situation. The sensor is placed under the hip of the patient but the patient lying down on an inclined bed, actually is supported by upper body, hip and legs. The model considered here assumes no connection between hip and other parts of the body. Because the forces between hip and other parts are unknown and complicated. This analysis certainly is overly simplified. However if we use three sensors and all three parts of the patient's body are supported by sensors and the results are added together. This analysis may be close to that case.

Consider that the weight of the block is W, the tangential component of the weight is Wt = W sinθ and the normal component of the weight is Wn = μW cosθ acting on the block in tangential direction is

FT = W sin θ - μW cos θ

If, FT < 0 , the block will not move, ifFT > 0 then the block will move down the slope.

The tangential force acting on the inclined plane (shear force measurement sensor) is

Fshear = Ff =μW cos θ

To verify the above analysis, we did one measurement with the setup as in Figure 5. A piece of plywood is used for the inclined plane with θ = 170, W = 2.73 kg. The shear force sensor is placed directly on the wood then another piece of wood is placed on the sensor and books used as the load, we had reading on the sensor of 0.25 V, from calibration Figure 4, it is found the shear is 0.90 kg. Because Wt = 0.8kg and Fshear = 0.9kg . Hence the block is not moving. Consequently we find the friction coefficient between wood and stainless steel is 0.345.This is a reasonable number.

Conclusion

Because we have not done actual measurement on patient so this report can be only considered as a progress report. Further research work should be done to make the work complete. However we did one measurement. That means the sensor is working. And from the analysis we find that the functional relation for the shear force on the support is.

Fshear = Ff =μ cos θ

This relationship should be fairly accurate. Further experiment can only prove it will not change it. This is our conclusion.

Appendix

Friction, Shear Force, and Shear Stress

Friction is the resistance that is encountered when two solid surfaces slide or tend to slide over each other. The friction force is known equals the normal force between the surfaces times the friction coefficient. When the surfaces are sliding the friction is smaller than that at stationary, because moving friction coefficient is smaller than static friction coefficient.

Shear force is a force that acts parallel or tangential to the surface. So friction is the shear force. When the shear force is divided by the area the force applied, it is called shear stress.

2019 Chevrolet Silverado - Review, Redesign

2019 Chevrolet Silverado – Review, Redesign – Showcased back in 2012, the actual Silverado is just not specifically new. Also, even though this is basically the secondly most popular vehicle on the market, it is really not the 2nd greatest when it comes to overall performance or basic features. The F-150 is superior is most techniques while the Ram memory 1500 has been tweaked towards the intense and is particularly closer than GM would like to the Silverado. Because of that GM is predicted to prepare a large update for your truck which could be launched with all the 2019 Chevrolet Silverado. To date, they haven’t really confirmed the point that the 2019 version is definitely the 1 but it appears as though it, especially considering that both Ford and Ram are likely to release new pickups inside the identical season. Basic Motors is recognized for doing work very difficult and enhancing new variations of the well-known trucks. Among the titles getting considered will be the redesigned Chevy Silverado 1500. If gossips are believed to be accurate than the completely re-designed and-new 2019 Chevy Silverado 1500 may be noticed in the near future.

2019 Chevrolet Silverado Review

United states van industry is definitely a very competitive one. Especially, if medium-sized to complete size pickup trucks are viewed, Us citizens could possibly have extremely fewer alternatives nevertheless the alternatives are filled with prospective and choosing any one is extremely difficult. Amazingly, or perhaps not, options are provided by the top a few American brands. Sealing horns using this type of 2019 Chevy Silverado 1500, we could anticipate seeing some Ford F-150s plus some Avoid Rams that are just as great and can prove to be incredibly very competitive. Assume a detailed combat in between these 3 and once the newest models of most 3 originate out, a success may be made the decision.

Aside from perhaps a new wheel design added to the choices collection or even a new color or two included in the outside paint color scheme, we anticipate the 2019 Silverado to handle more than creatively. Up-to-date for 2016, the truck’s basic physical appearance goes back to the last significant redesign for the 2014 design year. At least as far as large pickups go, the Silverado should continue being reasonably conservative looking, by using a box and wide-shouldered information, capped by bold trim-distinct entrance-stop treatments.

2019 Chevrolet Silverado Redesign

The truck’s interior is properly made with sizeable legible gauges, and large switches and dials in the dashboard; if so loaded there is a 7 or seven-inches touchscreen at the middle of the dash panel for Chevy’s easily enhanced MyLink infotainment method. All cab styles pay for ample headroom for tall riders putting on cowboy hats, although Team Cab devices deal with a trio of backseat passengers to limo-like legroom. The WT, LS, and LT designs need to stay offered in these three cab designs, the Custom with merely the Dual Cab, the LTZ in Dual and Crew cabs, and the Great Country as simply a Staff Cab.
