 a basis for selecting topologies for three different architectures, which consist of (i) the most important links, (ii) selected TRX nodes and (iii) hierarchical TX-RX topologies. With proper selection of only 8 ultra-low-complexity TX and 4 simple RX nodes, a classification accuracy of 91 % can be achieved on a very diverse posture set. The influence of measurement time and system bandwidth is analyzed for selected topologies of all three architectures and discussed in the context of implementation with UWB Impulse Radio.Post advice pertaining to anything you want, as long as you've found it helpful and true in your own life.
The person you think you are is miles away from the person most people experience when they interact with you.
Does this have to do with narcissism?

It's just my experience. Point being there's no point obsessing over what you are or aren't.
sometimes in life where you fall down and you don't feel the strength to get back up so you used to put a mask on your face when you go to school and pretend everything's okay when it's not and you come back home laying in your bed where no one is looking at you and you don't have to impress anybody and you are yourself. And then fear comes in. you know the fear that you have as soon as you walk into the door and you think someone broke into your house maybe? Maybe have doubt in your life? Maybe you don't know for sure what's going to be happening in the future and it scares you. Maybe you're worried about what people think of you and what people are saying about you? And that fear paralyzes you and you want to ask yourself today "do I have hope?"
Yeah, that feeling is...
Momentum is essential to change. If you don't keep the ball rolling, you will fall back into the same slump you were in before.
However recently, someone said something that made me feel emotional: "You know, you're really differently. Most people notice that. You're like a mystery without wanting to be one. You think, you belong nowhere but that's not true. Rather the opposite. The people you meet want rather belong to you. But you don't let them, because you are afraid. You radiate an openness, that many almost can not comprehend. At the same time you have such a reticence that you exclude yourself from others. You are just a paradox. And this is what makes you sick. You have an incredibly interesting life, always happens something to you. You always have new stories, new knowledge, new people to know. The only one who doesn't see that is you. All other see that and want to be part of it. But you will not let them. Probably because yourself are not part of it. See it as it is, not as it not."
 I fall into both categories from time to time, though. It's great advice.
Don't date anyone you meet in a pub.
Because the people who you meet there are not the type of people that you are looking for unless you are looking for a hookup.
 A real rookie mistake.
It's my great-grand mother's advice. But I agree, drink and woozy atmospheres are no way to check if a couple are compatible. Most likely they are on the make.
These guys know the score.
Never give up, always stand for what you believe in, and always love those who can't love themselves.Click Image to Enlarge
Tool-less, swing-up tail pulley permits 1-min belt exchange while retaining tension setting. Calibrations on both sides permit rapid, precise “balanced tension” where each increment represents the tension setting per foot of conveyor length.
As pulley width increases, a 1.25-in.-diam. pulley will deflect nearly five times more than a 1.86-in.-diam. pulley, and this effect is compounded when the pulley is weakened with a V-groove.
Based on data from a leading belt manufacturer, this illustrates how conveyor width can be limited by pulley diameter. This represents belting commonly utilized on low-profile conveyors. Belt rating is 8N/mm using a minimum recommended tension of 0.3% to ensure automatic belt tracking. The chart provides a technical approach to pulley selection to assist in achieving optimal performance of conveyor and belting and lower operating cost. CAUTION: The belting manufacturer notes that a V-groove for restraining the belt would have a negative effect and would void the chart data for this type of pulley.
Low-profile conveyors are ubiquitous in industry, typically used in 24/7 applications in packaging, assembly, labeling, inspection, and sorting. These are compact belt conveyors with 1- to 2-in. pulley diameters and maximum belt widths of 24 in. They form critical production links where unplanned downtime or time-consuming maintenance is intolerable.
The most critical areas of low-profile conveyors that draw maintenance attention are the belt itself and the pulley/bearing system. Speed, load, accumulation, and inclined operation increase forces on these components and cost. Incorrect belt tension can cause many problems, including bearing overload, miss-tracking, belt slippage., etc.
Correct tension varies with the application, but typically it will be 1/ft of conveyor length. It seems counterintuitive, but a belt that is under-tensioned can actually elongate in use, which leads to many belts in good condition being discarded, due to a conveyor’s limited tensioning capacity.
CENTERING WITH CROWNED PULLEYS
Following the recommendations of the major belt manufacturers, a crowned pulley with a correctly tensioned belt is the preferred way to achieve automatic belt centering..
Properly tensioned belts on crowned pulleys easily withstand moderate short-term lateral forces without major displacement from center. When side loads increase, a V-retainer on the underside of the belt can be added wear on the V-retainer.
Belt V-guide made of acetal plastic (such as DuPont’s Delrin), located opposite the point where the belt experiences side forces. These guides keep the V-profile fully constrained with reduced wear.
A normal V-retainer alone does not offer true “non-contact guiding” so it tends to drag against the sides of the groove and wear constantly. those based on silicone, PTFE, or polypropylene.
PULLYS: SIZE MATTERS
As noted, low-profile conveyor pulleys normally range from 1- to 2-in. diam., but this small range can produce a surprising difference in conveyor capacity and performance, as well as belt, cleat, and bearing life. Smaller pulleys may be needed for applications requiring a minimum height and moderate speeds and loads. However, logic dictates that a smaller-diameter drive pulley will have a much greater tendency to deflect as the conveyor width increases (a 1.25-in. pulley without a V-groove will deflect nearly five times more than a 1.86-in. pulley with the same load). This creates an inherent “traction” disadvantage for load-carrying purposes, and can negate the crowning effect (belt-centering capability) of the pulley. This is highly problematic in applications that involve wider conveyors, reversing, 2 in. and a correctly tensioned belt will carry twice the load at 24 in. wide that it does at 12 in.wide. This rule of thumb does not hold as pulley diameters approach the 1.25-in. range (see chart on p. 44).
Smaller pulley diameters—with their greater tendency to deflect—have limited ability to produce the proper belt tension to achieve automatic centering with a crowned pulley. The resulting loss of “traction” and self-centering are sometimes compensated for by lagging or knurling the pulley and substituting a longitudinal V-retainer for a crowned pulley. Because the pulley must now have a V-groove in its center, as well as being knurled, its rigidity is further compromised.
Belt manufacturers, too, discourage knurled pulleys because they invariably abrade the belt’s underside and resist tracking, which leads to a substantial reduction in belt life. Impacted debris in the pulley knurl or worn knurling can lead to belt slippage and miss-tracking, as well as accelerated wear of the belt, V-retainer, and pulley knurl. Abrasion can occur without any load on the conveyor, and it increases with belt speed. Debris from this abrasion may be unacceptable in food, pharmaceutical or cleanroom applications. Routine cleaning of the knurls is impractical because it requires stopping production and removing the belt.
Bearing life is also greatly affected by pulley diameter. A 1-in. pulley must run at twice the rpm of a 2-in.-diam. that is gaining popularity is the external shaft-mounted design. This unit is compact, provides “perfect alignment,” and eliminates all couplings, drive belts, chains, sprockets, guards, and tensioning. These drives can be radially positioned in 30° increments. and can be exchanged in less than 5 min when equipped with an optional plug connector.
If a conveyor is used for multiple applications at different speeds, a variable-speed drive may be desirable. This reduces wear and power consumption, and provides optimum speed for each application.
The service manual for a conveyor can give clues on preventive maintenance and troubleshooting. and tool-less guide-rail and belt-support removal and belt release that can permit a “one-minute” belt change on a stand-mounted conveyor. These options should be reviewed with the manufacturer,
