Estimating SCR installation costs

The goal of the Clean Air Interstate Rule (CAIR) signed into law almost a year ago is to reduce NO x emissions by 60%, relative to levels, across 28 eastern states and the District of.

Based on projections, models, sentiments and research, analysts strive to come up with an estimate of what the company will do in the future. Consensus estimates are not an exact science. All reports rely not only on financial statements which may be manipulated by management or other staff, with access to company records - they also involve inputs, such as footnotes, management commentary, research into the industry overall, peer companies, and macroeconomic analysis.

Generally, ratings from shares that have wide analyst coverage could be deemed more robust than those that have narrow analyst coverage.

If a company exceeds consensus estimates, it is usually rewarded with an increase in its share price. The bottom of the unit consists of a contoured magnesium alloy plate with a continuous O-right style seal along the entire perimeter. It is held securely in place by 18 small Philips screws they still come in different sizes; standardizing would be better. The whole assembly has an industrial high-tech look that always differentiates Getac machines.

The sole door in the bottom plate has eight rounded corner — no mere rectangles here — and is also neatly and precisely sealed via foam pressing against an o-ring-style metal lip. The hard disk caddy see image to the right is a remarkably intricate affair consisting of a metal outer housing heavily padded with different types of foam and neoprene.

The battery is a powerful You can't see the charge meter when the battery is installed in the unit, but it comes in handy when you carry spare batteries around.

The battery can be removed if the unit is plugged in, but it is not hot-swappable. The image below shows the inside of the Getac B Getting inside for service or maintenance is easy: There is no need for an internal frame or chassis here; the vault-like housing of the B is the frame and chassis. As a full-size rugged notebook, the B comes with a full complement of ports, all of which are protected either by rubber plugs or hinged doors.

The pictures below right show the left and the right side of the B, both with the doors open and closed. On the left side of the unit are the Media Bay and access to the main battery. The Media Bay is protected by a hinged door that snaps closed when two hooks engage. A spring-loaded lever releases the hooks. The door seals tightly when closed. The battery compartment has a double-locking mechanism. First you move a small lever to unlock the main lever. Then you move a larger lever to fully release the door.

Both levers go hard and it is unlikely that they'll ever open by accident. Our review unit also came with a Smart Card reader underneath the optical drive. On the right side you find access to the hard disk well, solid state disk these days , expansion ports, and a variety of other ports.

The hard disk caddy sits behind a double-lock door like the one used for the battery on the other side. The door closes and seals securely, but it cannot be locked, and thus provides potentially unwanted access to the hard disk. On the other hand, military and other customers often require the ability to quickly and easily remove the hard disk. A compartment next to it has separate microphone and headphone jacks, a spare cutout for an optional GPS antenna, an HDMI port, a springloaded SD card slot, an optional SIM card slot, and an unmarked RF switch that turns all installed radios on or off.

Along the backside of the B, which seems unchanged in layout compared to the original design, are the individually sealed power jack and an also individually sealed USB 3. The better part of the backside is taken up by a large hinged door that covers two 9-pin DB9 serial ports and a pin video port. The cover has an integrated sliding door that provides access to the expansion bus connector even while the main door is closed. On the right side is a Kensington lock slot, and there are two D-rings for a carry strap.

Most of the doors have metal hinges that are screwed onto the body and the actual door via two Philips screws each, making replacements very easy. The front of the unit does not have any connectors or ports other than two small speakers to the left and right of the LCD case clasp.

There wouldn't be room for anything else as most of the front is taken up the large, impressive looking magnesium handle that is screwed onto the system side of the computer. There are, however, five indicator lights built into the right side of the handle base. The B's key keyboard is full-scale. It has black keys with white labels. Instead of using less legible blue for function key combos, Getac used white for those labels also, but placed them in little white square boxes.

The company offers a waterproof backlit mechanical membrane keyboard and an optional waterproof backlit rubber keyboard. Here's what the two versions look like: Below the keyboard is a small and slightly recessed so you can feel its boundaries in the dark touchpad and two mouse buttons.

The touchpad is on the smallish side, but it's much more responsive than the one on its arch nemesis, the Panasonic 31 at least that's the way it was on the last CF31 Panasonic sent us for testing.

To the right is a fingerprint reader that has its own sliding door. Both available keyboards have a red backlight that can be set to come on automatically. It's pleasant and clearly illuminates the keys in semi and full darkness. One slight distraction is that when viewed from an angle, the red illumination peeking out between keys can overwhelm the actual illumination of the key. Above the keyboard are five hardware pushbuttons.

From left to right, they are: Power P1 function button turned display on and off on our unit ECO button for engaging power conservation mode under battery power High-Bright button turns display to full 1, nit power Light sensor engages light sensor adjustment of display brightness Having hardware buttons to turn quickly off the display and make it super-bright comes in very handy. It's much quicker than fumbling with menus. On the other hand, we wish the power button were elsewhere, as we often inadvertently pushed it, sending the unit to sleep.

Performance We do not envy the product planners and engineers who must decide what level of performance to bestow upon a rugged notebook. While high performance is always good, it means either a larger battery or less battery life, and it means more heat, which may make a fan necessary. Lower performance means longer battery life and less heat, but then the machine may be considered to be too slow. The challenge then becomes to find a happy medium and balance between performance, size, weight, battery life and heat generation.

Then add to that the fact that Intel has been releasing new chips and chip families at a furious pace, thus quickly obsoleting anything running on its older chips.

The design stays the same to guarantee complete compatibility with all peripherals and accessories, but the technology is continually updated. For the latest B, Getac not only switched from the 4th directly to the 6th generation of Intel's Core processors, but also moved from standard voltage CPUs with a high 37 watt thermal design power to much more power-efficient ultra-low voltage processors.

And Getac no longer offers a low end Core i3 processor option as those lack certain Intel technologies and popular features such as Intel's "turbo" mode. Getac also offers the mid-range Core iU and Core iU, which also differ in speed and certain Intel technologies. To view the full spec table for these four dual-core CPUs, see here. What is interesting here is that all available processors are of the "ultra-low voltage" variety, as compared to the "standard voltage" processors of the prior generation B Obviously, the heat generated by 37 watts requires much more cooling than that by 15 watts.

See what that means? Getac switched to ultra-low voltage processors that use less energy but, thanks to their advanced technology, provide the same or better performance than the older higher-wattage chips.

Less energy means you don't need the same big battery, or you get longer life out of a charge if you keep the same battery. Getac banks on these new processors being so efficient that they provide the same or better performance than the older chips, which means the B gets even better battery life from the same size battery.

It's like using am energy-efficient, high-tech 4-cylinder turbocharged motor instead of an old, low-tech V8 gas guzzler. Here's a brief explanation of Intel technologies that the iU and iU have, but the iU and iU do not: Skylake also brings Intel Authenticate, Intel's new enhanced hardware security that strengthens identity protection.

For connectivity, there are now three ultra-fast USB 3. The legacy RJ11 modem port is gone. In order to get a sense of how this latest Getac B performs compares to earlier generation Bs we tested in our lab, we installed Passmark Software's PerformanceTest 6. We also installed the CrystalMark benchmark suite that tests various subsystems and then provides an overall score. The results are below. Without forcing its customers to abandon their investment in B docking, peripherals and accessories going back almost a decade, Getac has managed to more than quadruple performance from the original design.

And that's without adding a fan, without putting in a much bigger battery, and without needing to change the basic, mature and field-proven platform. One could now argue that a decade's worth of rapidly advancing technology would easily allow a thinner, lighter wide-screen form factor, and that's undoubtedly so, and will be so at some point in the future.

But for now, it's fair to say that the B's original designers future-proofed this platform beyond any expectation. Power draw and battery life What does all of this very significant performance mean for the latest B's battery life? The competition has set the bar very high in this class, with Panasonic claiming 18 hours from the main battery and a combined 27 hours with their optional media bay secondary battery.

The last Dell 14 Rugged Extreme we tested clocked in at almost 15 hours. Looking at our testing archive, we found that the original B managed to reach a theoretical maximum battery life of almost 12 hours, and a 3rd generation i7-equipped B benchmarked a theoretical maximum battery life of 8 to 10 hours in As is our standard procedure, we used Passmark Software's BatteryMon power management benchmark utility to measure the B's power draw under various operating conditions.

That way we saw an idle power draw of 6. And at the maximum standard brightness setting, electric draw reached 9. Turning on the superbright backlight via push button, draw rose to The beefy Li-Ion battery of the B has a capacity of 96 watt-hours. Dividing that by the 6. That's just as Getac claims. In the maximum performance settings and with the superbright 1, nits backlight booster, theoretical battery life would drop to 4. As always, real world mileage will vary.

Minimum draw in a test lab is not an accurate predictor of actual battery life. However, it appears that the power management of the 6th generation "Skylake" Intel Core chips works very well indeed. Combine that with Windows 10's good power management and Getac's own extensive power management settings, and this latest B is more power-efficient than its predecessors despite vastly increased performance.

Getac's claim of 15 hours seems possible, and twice that via an optional second battery that goes into the media bay en lieu of the optical drive. Do keep in mind, though, that power settings do affect clock speed. Getac G-Panel The Getac B comes with an updated version of the Getac G-Panel that combines a number of special utilities and helper apps that make using the unit quicker and simpler than going to the standard Windows control panels, which can be a cumbersome process.

And here is what the G-Panel provides: You can also drill down for more detailed and technical data. It also shows the current power consumption. With the backlight at its lowest and all power savings measures engaged, the reading was as low as 5.

ECO displays and controls power savings settings. You can customize the settings and even have certain features such as Bluetooth, WiFi or the touch screen turned off. Antenna is where external antenna settings via pass-through connector or via docking station are configured. They pop up in their own windows, and the only additional wish I'd have is being able to set the graph upper and lower limits.

Note that Getac has a variety of additional G-Panel modules that cover areas such as sensors, vehicle ignition, etc. QuadraClear display technology Most rugged notebooks will be used outdoors and sometimes in bright, direct sunlight.

Standard transmissive LCD displays, however, wash out in daylight, and that's why over the past decade or so, sunlight-readability has become a major selling point in the rugged notebook sector. Getac generally calls theirs "QuadraClear" see QuadraClear page. The term derives from its four core features: All major manufacturers of outdoor-usable mobile computing equipment use those technologies, and so the difference boils down to a backlight brightness and b the extent to which the expensive optical coatings are applied and how the various layers are bonded the fewer reflective surfaces, the better.

Getac calls their layer bonding process "LumiBond" see LumiBond page. All else being roughly equal, display backlight power then determines the all-important effective contrast ratio which then translates into the degree of real world outdoor readability.

And backlight strength is what sets the B apart. Some manufacturers up the brightness in their rugged products, usually into the nits range. Getac offered the original B with nits, but beat everyone with an optional superbright 1, nits backlight. In later generations, including this latest one, they upped the ante with an optional industry-leading 1, nits backlight. The super-bright 1, nits LED light is considerably brighter than the maximum of the standard brightness range. To engage it you push a special button above the keyboard.

Turn it on and the screen lights up with an intensity unseen in any regular display. Having that hardware button is also the key to keeping power draw in check: When you don't need it anymore, turn it off. That's much easier with a button than via menus and software sliders. How does it all work in real life? The pictures below show different scenario comparisons between the B and a The iPad Pro has an excellent display with a maximum brightness of about nits.
