There are a number of Fire Safety Publications available online in many languages, including English, Spanish, Chinese, Russian, and more. FDNY has a strong educational presence online where fire safety tips are shared at FDNY Smart. New York City has two locations where the public can interact with FDNY educators: the FDNY Fire Zone and the New York City Fire Museum. There are also programs such as the Juvenile Fire Setters Intervention Program that focuses on preventive measures with children who are playing with fire or setting fires intentionally. Through the FDNY Fire Safety Education Program, members teach strategies that reduce fire deaths and injuries, while focusing on fire prevention. This is done through many programs offered by the FDNY that focus on the city's most vunerable populations, including children and senior citizens. To that end, FDNY members are sworn to serve and protect life and property.Ī fundamental mission for FDNY is to protect the lives and property of New York City residents and visitors. This accomplishment requires a steadfast and daily commitment to maintaining the department's core values. Since its inception in 1865, FDNY has helped lead efforts to make New York the safest large city in the nation. FDNY not only responds to more than a million emergencies each year, its personnel also work to continually educate the public in fire, life safety, and disaster preparedness, along with enforcing public safety codes. The Department's main goal is to provide fire protection and other critical public safety services to residents and visitors in the five boroughs of New York City. ![]() AgeĪpplicants must be 18 years of age at the time of hire.The New York City Fire Department, an NCCRS member since February 1982, is the largest Fire Department in the United States and is universally recognized as the world's busiest and most highly-skilled emergency response agency.

![]() ![]() The Matlab/Octave scripts used for finding the design parameters can be downloaded here. The LTspice simulations for all examples can be downloaded here. The voltage representing the transfer function is scaled so as to be constant with variations of the source amplitude ampl and amplifier gain value gain.ĭownloadable LTspice Simulations and Matlab/Octave Scripts These represent the peak displacement of the cone in millimeters, the SPL at distance dist, and the transfer function G( s) (or H( s) if it is an assisted alignment) respectively. On the right side of Figure 3, three test voltages are provided, denoted by displacement_mm, SPL and transfer_function. Given a correct computation of the element values, a direct, one-to-one relationship is established between the synthesis and analysis, allowing for verification of both the design equations and the software code for solving them. It can be seen in Figure 3 that reflecting all electrical and mechanical elements to the acoustical side of the circuit will result in an acoustical analogous circuit of identical form to Figure 1. This simplifies the equivalent circuit and the computations of the element values from the driver Thiele-Small parameters. The effective mechanical mass M MS is really the sum of the mechanical mass M MD of the driver diaphragm assembly itself, plus the acoustic mass loads on the front and back of the driver reflected through the transformer to the mechanical section. To ensure that G( s) has the form of a high-pass filter function, the voice coil inductance is neglected. All parameters are in MKS units unless they explicitly have a units suffix as in e.g. The parameter dist is the distance in meters, used to compute the dB SPL. The box volume in cubic feet, box tuning frequency in Hz and box Q are entered as VBcuft, fBox and QL respectively. param statements under "Measured driver parameters". The Thiele-Small parameters of the driver are entered as. When such a filter is used, its transfer function is entered as a Laplace expression for the scale factor of a voltage-controlled voltage source. For assisted alignments, a filter (not shown) is placed between V1 and E2. Voltage source V1 represents the preamp output voltage, while voltage-controlled voltage source E2 represents a power amplifier with THX-compliant gain. The circuit keeps the electrical, mechanical and acoustical portions separate to allow for easy probing of different types of physical quantities without resorting to transformations between the electrical, mechanical and acoustical domains. Simulation Schematic of a Typical Unassisted Vented Box Alignment The schematic of a typical simulation is shown below in Figure 3.įigure 3. In contrast, the simulations provided here are structured so that the transfer function of the loudspeaker plus box is identical to G( s) given in Small and here in (1), with transfer function coefficients given by (14) - (17). Leach's approach includes the effects of more complex phenomena than those usually considered, including mutual coupling between the port and driver, as well as a more complex model of radiation impedance than the acoustic mass loading that's typically used. The simulation technique is a variant of the approach used by Leach, except that it uses the free LTspice simulator, originally from Linear Technology. Schematic and Description of Typical Simulation In some cases, alignments with little or no practical usage will arise. All the possible alignment classes are evaluated for each n value of the assisted alignments: one fifth-order, three sixth-order, three seventh-order and six eighth-order. A collection of assisted alignments of order n from 5 through 8 will be designed, analyzed and compared to the unassisted alignments with add-on high-pass filters to determine if there is any advantage to incorporating the filters into the design process itself. First, an unassisted system will be examined without any external filter, then with four different add-on high-pass filters. Simulations of frequency response and displacement will be performed. These simulations will all use the Dayton RSS390HF-4 driver, which is well suited to large vented-box subwoofers having a -3dB frequency in the neighborhood of 20 Hz. In order to verify the theoretical results, debug the related design software and evaluate potential designs, a collection of SPICE simulations of various systems will be performed in this section and the results presented. Simulating Designs Using SPICE General Approach ![]() Talk about the fact that you pretty much find Once again, we'll talkĪbout why in the next video when we talk about someĮlectron configurations. They're colorless gases,Īnd they're generally very unreactive. We're actually going to comeīack to that in the next video when we look at someĮlectron configurations and we talk about why these So they're often veryĬolorful, very, very corrosive, and the name halogenĪctually means salt former. Group 7A, or group 17, things like fluorine,Ĭhlorine, bromine. Of the nonmetals now, and that would be the halogens. So you find nonmetals inĭifferent states of matter. Have a solid nonmetal, those solids would tend toīe brittle, not malleable like metals. Copper wires, of course,Ĭarry current in homes. Metals are alsoĭuctile, which means you can draw them into wires. Metals, theĪt room temperature, except for mercury. Let's just go ahead and say- groups 3 through 12. ![]() And so once again, theĬhemical properties, and so that's, again,Ī convenient way of organizing the periodic The metals in group 1, but you don't find these Metals are reactive- not quite as reactive as Things like magnesiumĪnd calcium and strontium are your alkaline earth metals. So let me go ahead andĭraw that in green here. Let's talk about hydrogen,īecause hydrogen is also in group 1, but hydrogen Nature in combination with other elements. Walk outside and find some sodium lying on the ground. Going to find them in their pure state in nature. Turn out to be so reactive that you're not Organizing elements into groups is elements in the same Soft, silvery metals that are extremely reactive. In group 1, or group 1A, so things like lithium,Īnd sodium, potassium. Room, and we're not really going to talk about all With numbering my periods, so this would be So lithium, beryllium, boron, carbon, nitrogen, oxygen,įluorine, and neon. Hydrogen is in the first period and so is helium. Period 1, and I just move across my periodic table, Numbering your groups is useful when you're thinkingĪbout valence electrons. ![]() This group 3A, group 4A, group five 5A, groupĦA, 7A, and finally 8A. Groups 3 through 12, continue on with your That group 1 is group 1A, group 2 is group 2A. To number your groups, and that would be to say Up to here, and I can see I have another verticalĬolumn, so group 13, 14, 15, 16, 17, and finally 18. So all these elementsĪre in the same group, and we call this group 2. Of these elements are also in the same column. So all these elementsĪre in the same group. See that all of these elements are in the same vertical column. The groups are the verticalĬolumns on the periodic table. This types of changes involve the nuclei of atoms and are therefore in the realm of nuclear chemistry which is a more specialized field of chemistry which is rarer to encounter. Anytime you want to change an atom into a new element you must change the number of protons in the nucleus either by adding or removing them. Since our new nucleus has a different number of protons than the original nuclei, we have created a new element different from the original two. This is the most common case you will encounter in chemistry.ģ) At very high energies we can get the atoms of different elements moving so fast so that when they collide their nuclei can fuse into one larger nucleus. With a chemical reaction even though chemical bonds have been broken and reformed to create a new chemical, we haven't touched the protons in the nucleus and therefore haven't changed the elements involved. Which as we know is a chemical compound composed of the elements hydrogen and oxygen. Using the hydrogen and oxygen gas example, if we added those gases together and introduced a source of heat like a flame, they would react and combine to form water. Now there is enough energy to break chemical bonds and conduct a chemical reaction where the atoms of different elements can combine into a compound composed to atoms from both elements. For example, if I combine hydrogen and oxygen gas together at low temperatures then I just have a vessel filled with unreacted gas.Ģ) At higher energies we start creating the situation suitable for reactions to occur. You just get a mixture of different types of atoms. Combining two atoms of different elements together depends on how much energy you put into such a collision.ġ) At low energies (think low temperatures essentially) putting together two samples composed of atoms of different elements doesn't usually create a reaction. So in practice we're not really combining elements rather atoms of different elements. So elements are different types of atoms which are differentiated by their atomic number (the number of protons). ![]() Best of all, it’s free to download and use!

![]() This then shows the areas of concentration and sparseness. In a dasymetric dot map, dots are placed in areas of greatest density. Both are intended to show relative density, but they are created from very different data sources and use very different techniques. There are two primary types of dot density maps. Snow petitioned the local authorities to remove the pump's handle, and when the handle was removed, there was a dramatic decrease in cholera cases for the immediate area. The map showed that a high number of deaths were occurring near a water pump on Broad Street at Cambridge Street. Cholera deaths were depicted along the road network in their correct locations by address and measured by marks stacked next to the road. He symbolized all of the water pumps throughout the area. The study area was outlined along the relevant road centerlines. The base map was a simple road network, with few buildings named or depicted. Snow's map of the 1854 Broad Street cholera outbreak in London was simple and effective in its design. ![]() He found that cholera is not transmitted through the inhalation of infected air but through the ingestion of contaminated water or food. John Snow created a dot distribution map that settled a debate between two schools of thought. ![]() In 1854, when a large outbreak occurred in London, Dr. Cholera cases are highlighted in black.ĭuring the 1850s, cholera was a large problem throughout England. If a smaller unit area, such as counties, were used to organize the data, the dots would be located closer to their real-world position. For example, if the number of farms in each state of the United States was being represented on a dot density map, a state with few farms, such as Arizona, would have dots spread far apart within its boundaries. This allows the placement of the dots to be closer to the actual locations of the features being mapped, portraying a more accurate distribution within each area. Due to the random placement of the dots within each area represented on the map, it is important to use the smallest unit area possible to display the data. In a dot density map, the dots are all the same size and do not represent actual point locations of data. Dots in dot density maps do not represent the locations of things they represent a summary of data for a given area.ĭot density is an effective method to visualize concentrations of quantitative data. ![]() For example, a map of a state with dots representing locations of fast food restaurants would not be considered a dot density map. There are two types of dot maps, produced through very different techniques, but to similar effect: 1) point feature maps, based on point data representing the location of every individual in the population, and 2) choropleth dot maps, using the same kind of polygon/aggregate-attribute data used for choropleth maps, but showing the value of each district using a number of randomly placed dots rather than a solid fill color.Įach dot in a dot density map represents an aggregate of information. Thus, areas with more dots indicate higher density/concentration. Each dot may represent either a single individual, or a representative group of individuals, and dots are placed according to the precise or estimated locations of these individuals or groups, usually using GIS data. Dot density maps can be a good alternative to choropleth maps because you can show the raw variable without normalizing it because the map viewer still gets an idea of how it is distributed. Dot density map showing concentrations of population 21+ in Ohio.Ī dot density map is a type of Thematic map that uses large numbers of dots or points to portray the relative geographic distribution of a population of some kind (e.g., people, livestock, businesses). ![]() Now you can play this game without any interruption.Open this file and click on the install button present on bottom right.Open the android folder and then search for the 8 Ball Pool Mod APK file.After the download it completed, go to the file manager of the phone.Now go to the downloading link and click on it.Do not worry about this warning because this game is highly safe to be downloaded.Now enable this option and you will see a warning message popping up on the screen.Now open the security tab and then find unknown sources.To install this amazing and most favorite game in mod version, first go to the settings of your android or iPhone.Ti is available for both Android and iOS users. ![]() ![]() TOP game bi-a hp dn nht trên PC, mô phng c ch vt lý vô cùng chân tht, mang n tri nghim chi.
