This combines crushed peppermint with mini chocolate chips. You can also try a Peppermint Bark Martini Scone. Sprinkle a few sprigs of mint for garnish. ![]() ![]() Combine the above mentioned ingredients and stir until cold. You can also make a zero proof version of the cocktail. But, if you want a peppermint martini that is dairy free, you can substitute full fat coconut milk for the heavy cream. Adding some cocoa powder to the cocktail adds a rich creaminess that goes wonderfully with the minty flavors of the martini. If you prefer a smoother drink, try making a chocolate martini. This will presumably add a touch of sparkle to the cocktail. You can dip the rim in melted chocolate or coat it with crushed peppermint bark.Īnother option is to rim the rim with a crushed candy cane. The chocolate syrup on the rim adds a touch of visual appeal. One of the best parts of this festive martini is the rim. This tasty martini is perfect for the holidays or any other special occasion. Its creamy texture is reminiscent of the delicious chocolate and peppermint flavors of a classic peppermint candy. Peppermint Bark Martini is an alcoholic drink with a creamy peppermint flavor. If you can’t find a peppermint schnapps, you can also add a splash of white creme de menthe. You can buy a brand that’s flavored with a variety of spices, such as cinnamon and vanilla. The best way to make the white Russian is to use a good brand of peppermint schnapps. But the real star is the peppermint schnapps, which gives the beverage its unique peppermint flavor. It can be made with heavy whipping cream, half and half, or whole milk. The best White Russian is a rich cocktail that is creamy and sweet. You can add more liqueurs to the mix to create a stronger flavor, but the basics of the cocktail are all that are necessary. The best White Russian is a cocktail that is made with the best of all the above ingredients. For years, the drink was thought of as a non-alcoholic and a bit gaudy, but the Coen brothers revived the drink in the 1998 film The Big Lebowski.Ī White Russian is made with a variety of ingredients, including Kahlua, vodka, milk and peppermint schnapps. The first version was called the Black Russian, and it was created in the 1940s. The White Russian is a drink that originated in the United States.

![]() You need to place at least two screws in a row and space them about 18” apart. Then, we secured the first board to the rim joist using 2-¾” deck screws matching the color of the decking. We then placed the next section to see if any boards needed to be adjusted. This allows the boards to fit together in a seamless finish.Īfter, we checked the fit by clamping the board into place and cutting the next section. To install the boards, we measured one section and cut the square-edge board to that measurement with a 45-degree angle. The fascia will be placed on the front of the framing to hide the pressure-treated lumber. Make sure you keep this in mind when you install all the deck boards and adjust accordingly. Because of our temperatures being so cold in winter, our gap needed to be ½”. For example, the boards around our house and fence needed a gap of ¼”-½”. We will use the Grooved-Edge boards for the main part of the decking.Īlso, the decking boards needed to have gaps between other decking boards but also structures. ![]() The Square-Edge boards we will be using for the fascia and the picture frame border. We are also using two different profiles: Square-Edge and Grooved-Edge. We are using the Enhance Naturals in the color Rocky Harbor. In this tutorial, we are using Trex composite decking.Īnd within Trex, there are different styles and profiles. There are different types of material that can be used for decking. If you want your deck to look custom and professional, I would recommend doing the next two steps because it brings it all together. Although we are using pressure-treated lumber, it doesn’t hurt to take one more step to ensure that the framing will last for many years. This tape helps protect the joists from moisture. Install all the joists with a joist hanger. I also bent the angled joist hanger to fit the angle of the end joist in some areas. Also, I attached one screw through the end joist (or beam) to the joist, then attached the hanger. SIDE NOTE: I found it helpful to use clamps to hold the board in place. SIDE NOTE: Remember that the blocking should be no more than 12” from the outside edge to the center and they need to be spaced no more than 50” apart.Īttach the cut joists to the end joist with a joist hanger and the recommended screws. Next, we cut the board to length using the sliding t-bevel to give us the angle at the saw.Īfter, place the cut joist in the location with the TuffBlock at the ends and in the middle, if needed. Then, we measured the board so that it would be 16” on center from the last joist.įrom there, we used the t-bevel to determine the angle and then we measured the length of the board. To cut the joist at an angle, we placed the board onto the framing in the general location where it would be installed. Here is a diagram of our decks framing from our planning: Depending on the size of the deck, there could be a center beam running between the two outside boards.This is done by using ‘sleepers’, which are short boards running between the joists to provide extra support. ![]()

![]() ![]() SCR Performance is proud to offer Loveland and Colorado residents with a complete array of automobile services including timing belt services. You can also check your owner’s manual for the manufacturer’s recommendation as well. That’s why highly rated auto mechanics recommend replacing your timing belt every 60,000 to 100,000 miles. Unfortunately, sometimes there are no obvious signs that your car’s timing belt is need of repair. Whether your timing belt is missing teeth, or it has snapped completely, this can have a tremendous effect on your car’s RPM meter. If you’ve noticed that your RPMs (revolutions per minute) have started to act strange, it could be an indication that something is wrong with your timing belt. As a result of this excess work, your car will expel more exhaust than it should. This can make your engine work harder than it’s supposed to in an attempt to run under duress, which can lead to costly repairs down the line. If your car’s exhaust has been expelling far more smoke than you’re used to, it could be related to an issue with your timing belt. This can lead to your engine overheating and a handful of other expensive repairs. An oil leak may also occur when the gasket between the engine block and timing cover wears out or is cracked. While your timing belt cover may be secured by a series of nuts and bolts, it is very likely that they can come loose over time. If you start to notice oil around your engine, your vehicle may be experiencing a leak, which often occurs from the timing belt cover. You Notice An Oil Leak Near The MotorĪnother common sign that your timing belt is in bad shape is an oil leak. This can cause serious damage to cylinder head hardware like rocker arms, push rods, or valves. Oftentimes, the timing belt will break while the car is in motion. When your timing belt is broken, you won’t be able to drive your car at all. This means when you turn the key, you may hear the starter motor engage, but since the timing belt is responsible for operating the crank and shaft, it will not fully ignite. When your car’s timing belt is broken or irreplaceable, your engine will not be able to ignite or turn over properly. This could also be an indication of low oil pressure as well. When your car’s timing belt starts to wear out, it may produce a ticking sound inside of the motor. The expelled gases then exit through the exhaust manifold. The camshaft, on the other hand, operates the cylinder head valves and rocker arm assembly, which sends fuel to the combustion chamber. The crankshaft powers the engine’s connecting rods, which are attached to pistons inside of the combustion chamber. The timing belt in your vehicle is attached by a series of pulleys that go to the engine’s crank and cam shaft. If you hear a ticking noise coming from your car’s engine, there could be something seriously wrong with your timing belt. You Hear A Ticking Noise Coming From The Engine If you notice any of the below symptoms in your vehicle, contact our auto shop today. In this blog, we’ll look at a few common symptoms that may indicate your timing belt needs repair.Īt SCR Performance in Loveland, our certified mechanics have helped hundreds of people repair and replace their worn out timing belt with a new model. Your car’s timing belt can be found under a timing cover near the front of the engine, and since it is likely manufactured from high-quality rubber, it will need to be replaced from time to time. ![]() The timing belt is an internal engine component that rotates the engine’s cam and crankshaft in sync, ensuring each cylinder fires at the appropriate time. ![]() While you may not pay close attention to your car’s timing belt, it plays an important role in the mechanics of your vehicle. ![]() ![]() It calls for the state to invest $4,000,000,000 from the general revenue surplus and redirect another $3,000,000,000 in spending to the Florida Department of Transportation over the next four years.

Although such an aperture can provide substantially higher round-trip losses for higher-order resonator modes, compared with those for the fundamental mode, it also introduces diffraction effects. Such effects can also occur, for example, when trying to force a laser into single transverse mode operation (for optimum beam quality) by inserting a hard aperture into the laser resonator. The hard aperture introduces high optical frequencies, corresponding to rapid spatial changes of intensity. Such diffraction effects can be well understood and calculated based on Fourier optics. Figure 5: Same as Figure 4, except that a soft aperture is used. The simulation has been done with the software RP Fiber Power. Figure 4: Intensity profiles of a light beam directly behind a hard circular aperture (blue curve) and at some distances behind the aperture in steps of 25 mm. For a soft aperture (Figure 5), causing a smooth intensity drop at the edge, the diffraction pattern is smoother. During the further propagation in air, the intensity profile develops a complicated structure due to diffraction. Only after some distance behind the aperture, characteristic diffraction effects can be observed.įigure 4 shows a simulated example, where an originally Gaussian beam has been truncated at a centered circular hard aperture. If a light beam (for example a laser beam) encounters some aperture which transmits the light in some regions and blocks it otherwise, the immediate effect on the transmitted light is only the corresponding truncation of the intensity profile. Figure 3: Diffraction patterns at the same slit for all colors. The patterns for longer wavelength involve correspondingly larger diffraction angles. Figure 2: Intensity profile for diffraction of light at 450 nm at a double slit with 5 μm slit spacing and 1 μm slit width.įigure 3 shows with a color scale the interference patterns for different wavelengths. The intensity profile is further slowly modulated with a function determined by the finite width of each slit. The first installation arises from the interference of field contributions from the two different slits. As he had no laser, he had to achieve spatially coherent illumination of the two slits by using a third narrow slit before them.įigure 2 shows a calculated intensity profile for one particular wavelength. In his famous double-slit experiment of 1803, Thomas Young used two closely spaced narrow optical slits. The intensity profiles can be described with sinc 2 functions. For longer wavelengths, the central peak is broader, and the side peaks appear at larger angles.įigure 1: Far-field intensity profiles for diffraction at a single 1 μm wide optical slit, with wavelengths from 400 nm to 750 nm in steps of 50 nm.įor a given wavelength, the first minimum of the intensity occurs where the phase difference of contributions from the two edges of the slit reaches.For each wavelength, there is a main maximum in the middle, and they are much weaker side maxima at larger angles.Behind the slit, one can observe a diffraction pattern (see Figure 1) with the following features: Diffraction at a Single SlitĪ common situation is that a narrow optical slit is uniformly illuminated with spatially coherent radiation from a monochromatic laser. Diffraction also plays a crucial role in many other devices, such as optical resonators and fibers. In fact, the operation principles of various optical devices are essentially based on diffraction (→ diffractive optics). Some typical examples of diffraction effects are discussed in the following sections.Īlthough in everyday life one rarely encounters substantial diffraction effects with light, such effects are very common in optics and laser technology.

From the analysis of contention based MAC protocols in term of energy consumption, it was being observed that protocols based on preamble sampling consume lesser energy than protocols based on static or dynamic sleep schedule. It was analyzed that contention based MAC protocols are less energy efficient as compared to hybrid MAC protocols. A comparison with respect to energy reservation scheme, idle listening avoidance, latency, fairness, data synchronization, and throughput maximization has been presented. ![]() This study also aims to give reader a better understanding of the concepts, processes and flow of information used in these MAC protocols for WSN. The goal of this comparative study is to provide a basis for MAC protocols and to highlight different mechanisms used with respect to parameters for the evaluation of energy and transmission efficiency in WSN. These nine protocols are classified in contention based and hybrid (combination of contention and schedule based) MAC protocols. In this paper, nine MAC protocols which includes S- MAC, T- MAC, Wise- MAC, Mu- MAC, Z- MAC, A- MAC, D- MAC, B- MAC and B- MAC+ for WSN have been explored, studied and analyzed. There are number of MAC protocols that exist in the literature proposed for WSN. The design of a MAC protocol should also address the issues of energy efficiency and transmission efficiency. The MAC protocols are responsible to communicate and coordinate between nodes according to the defined standards in WSN (Wireless Sensor Networks). International Nuclear Information System (INIS)ĭata communication between nodes is carried out under Medium Access Control ( MAC) protocol which is defined at data link layer. Mac protocols for wireless sensor network (wsn): a comparative study A modification of the protocol is then proposed to eliminate the need for some nodes to stay awake longer than the other nodes which improves the energy efficiency, latency and throughput and hence increases the life span of a wireless sensor network. ![]() A new protocol is suggested to improve the energy efficiency, latency and throughput of existing MAC protocol for WSNs. S†MAC uses a few innovative techniques to reduce energy consumption and support selfconfiguration. This paper introduces different types of MAC protocols used for WSNs and proposes S†MAC, a Mediumâ€∊ccess Control protocol designed for Wireless Sensor Networks. Meanwhile, the sensor network should be able to maintain a certain throughput in order to fulfill the QoS requirements of the end user, and to ensure the constancy of the network. ![]() A lot of work has been done to minimize the energy expenditure and prolong the sensor lifetime through energy efficient designs, across layers. Since, sensors typically operate on batteries, replacement of which is often difficult. Power Saving MAC Protocols for WSNs and Optimization of S- MAC Protocolĭirectory of Open Access Journals (Sweden)įull Text Available Low power MAC protocols have received a lot of consideration in the last few years because of their influence on the lifetime of wireless sensor networks. In addition, this book also presents the design and evaluation of an adaptive MAC protocol for medical CPS, which exemplifies how to facilitate real-time and reliable communications in CPS by exploiting IEEE 802.15.4 based MAC protocols. The evaluation analysis of IEEE 802.15.4 for CPS therein will give insights into configuration and optimization of critical design parameters of MAC protocols. This book provides a literature review of various wireless MAC protocols and techniques for achieving real-time and reliable communications in the context of cyber-physical systems (CPS). ![]() |
