Sketch a picture of the tank and select an appropriate frame of reference. Although newer technologies are already introduced in the medical sciences to save records size, Big Data provides advancements by storing a large amount of data to improve the efficiency and quality of patient treatment with better care. This related differentiation and integration in ways which revolutionized the methods for computing areas and volumes. Definitions and application of the term vary greatly in the literature, spanning from the integration of content within a single lecture to the integration of a medical school’s comprehensive curriculum. The work done over the interval \([x_{i−1},x_i]\), then, is given by, \[W_i≈F(x^∗_i)(x_{i}−x_{i−1})=F(x^∗_i)Δx.\], Therefore, the work done over the interval \([a,b]\) is approximately, \[W=\sum_{i=1}^nW_i≈\sum_{i=1}^nF(x^∗_i)Δx.\]. Given that the weight-density of water is \(9800 \, \text{N/m}^3\), or \(62.4\,\text{lb/ft}^3\), calculating the volume of each layer gives us the weight. In this case, we have, Then, the force needed to lift each layer is. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. \nonumber\], We again recognize this as a Riemann sum, and take the limit as \(n→∞.\) This gives us, \[ \begin{align*} m =\lim_{n→∞}\sum_{i=1}^n2πx^∗_iρ(x^∗_i)Δx \\[4pt] =\int ^r_02πxρ(x)dx. This is a medical device that uses a property of an ellipse to treat gallstones and kidney stones. Our website is made possible by displaying certain online content using javascript. Problem-Solving Strategy: Solving Pumping Problems. Pressure is force per unit area, so in the English system we have pounds per square foot (or, perhaps more commonly, pounds per square inch, denoted psi). Digital imaging and medical reporting have acquired an essential role in healthcare, but the main challenge is the storage of a high volume of patient data. We now consider work. Take the limit as \(n→∞\) and evaluate the resulting integral to get the exact work required to pump out the desired amount of water. The work done to stretch the spring is \(6.25\) J. \end{align*}\], Note the change from pounds to tons (\(2000\)lb = \(1\) ton) (step 4). We then turn our attention to work, and close the section with a study of hydrostatic force. Adding the forces, we get an estimate for the force on the plate: \[F≈\sum_{i=1}^nF_i=\sum_{i=1}^nρ[w(x^∗_i)Δx]s(x^∗_i).\], This is a Riemann sum, so taking the limit gives us the exact force. Figure \(\PageIndex{2}\) shows a representative segment of the rod. Then, the force exerted on the plate is simply the weight of the water above it, which is given by \(F=ρAs\), where \(ρ\) is the weight density of water (weight per unit volume). Consider the work done to pump water (or some other liquid) out of a tank.

Watch the recordings here on Youtube! The water exerts a force of 748.8 lb on the end of the trough (step 4). \label{eqHydrostatic}\]. Let \(ρ(x)=3x+2\) represent the radial density of a disk. Select a frame of reference with the \(x\)-axis oriented vertically and the downward direction being positive. \end{align*}\]. The healthcare industry has traditionally been a quick adopter of new technologies, but it’s quite slow when dealing with data, especially data sharing and integration. There are also some electronics applications in this section.. Large numbers of research papers on big data in the medical field are studied and analyzed for their impacts, benefits, and applications. I am sure this book will be highly informative and interesting reading material for the students of B.Pharm, Pharm D and M.Pharm and other related course in the field of Pharmaceutical Sciences.

Medical imaging: Automation of analysis of medical images by the use of machine learning has the potential to be one of the biggest application of healthcare AI. The upper limit remains \(540\). We cannot apply the formula \(F=ρAs\) directly, because the depth varies from point to point on a vertically oriented surface. Out of all of the industries that technology plays a crucial role in, healthcare is definitely one of the most important. We obtain, \[F=\lim_{n→∞}\sum_{i=1}^nρ[w(x^∗_i)Δx]s(x^∗_i)=\int ^b_aρw(x)s(x)dx. Application of Mechatronics in Advanced Manufacturing. We orient the system such that \(x=0\) corresponds to the equilibrium position (Figure \(\PageIndex{4}\)). Consider a block attached to a horizontal spring. Although in the real world we would have to account for the force of friction between the block and the surface on which it is resting, we ignore friction here and assume the block is resting on a frictionless surface. Example \(\PageIndex{4}\): A Pumping Problem with a Noncylindrical Tank. Taking the limit as \(n→∞\), we get an expression for the exact mass of the rod: \[ \begin{align*} m =\lim_{n→∞}\sum_{i=1}^nρ(x^∗_i)Δx \\[4pt] =\int ^b_aρ(x)dx. The actual dam is arched, rather than flat, but we are going to make some simplifying assumptions to help us with the calculations. Summing the work required to lift all the layers, we get an approximate value of the total work: \[W=\sum_{i=1}^nW_i≈\sum_{i=1}^n62.4πx^∗_i \left(4−\dfrac{x^∗_i}{3}\right)^2\,Δx. Mass–Density Formula of a Circular Object, Let \(ρ(x)\) be an integrable function representing the radial density of a disk of radius \(r\). Note we often let \(x=0\) correspond to the surface of the water. The following problem-solving strategy lays out a step-by-step process for solving pumping problems. We can use integration to develop a formula for calculating mass based on a density function. We orient the disk in the \(xy-plane\), with the center at the origin. In this state, the spring is neither elongated nor compressed, and in this equilibrium position the block does not move until some force is introduced. According to Healthcare IT News, health care facilities in California, Kentucky, Maryland, and the District of Columbia have been hit with ransomware attacks recently. So the pressure is \(p=F/A=ρs\). The use of health IT can improve the quality of care, even as it makes health care more cost effective. When \(x=−0.2\), we know \(F(x)=−10,\) so, \[ \begin{align*} F(x) =kx \\[4pt] −10 =k(−0.2) \\[4pt] k =50 \end{align*}\], and \(F(x)=50x.\) Then, to calculate work, we integrate the force function, obtaining, \[\begin{align*} W = \int ^b_aF(x)dx \\[4pt] =\int ^{0.5}_050 x \,dx \\[4pt] =\left. Consider a thin rod oriented on the \(x\)-axis over the interval \([1,3]\). Let \(ρ(x)=\sqrt{x}\) represent the radial density of a disk. Then the work to lift the \(i^{\text{th}}\) layer of water \(W_i\) is approximately, Adding the work for each layer, we see the approximate work to empty the tank is given by, \[ \begin{align*} W =\sum_{i=1}^nW_i \\[4pt] ≈\sum_{i=1}^n156,800πx^∗_iΔx.\end{align*}\], This is a Riemann sum, so taking the limit as \(n→∞,\) we get, \[ \begin{align*} W =\lim_{n→∞}\sum^n_{i=1}156,800πx^∗_iΔx \\[4pt] = 156,800π\int ^{10}_2xdx \\[4pt] =156,800π \left( \dfrac{x^2}{2}\right)\bigg|^{10}_2=7,526,400π≈23,644,883. Both are defined as kilograms times meters squared over seconds squared \((kg⋅m^2/s^2).\). (Note that if we select a frame of reference other than the one used earlier, we may have to adjust Equation \ref{eqHydrostatic} accordingly. If the rod has constant density \(ρ\), given in terms of mass per unit length, then the mass of the rod is just the product of the density and the length of the rod: \((b−a)ρ\). We can apply Pascal’s principle to find the force exerted on surfaces, such as dams, that are oriented vertically. For pumping problems, the calculations vary depending on the shape of the tank or container. Assume a tank in the shape of an inverted cone, with height \(12\) ft and base radius \(4\) ft. A water trough 15 ft long has ends shaped like inverted isosceles triangles, with base 8 ft and height 3 ft. Find the force on one end of the trough if the trough is full of water. =\int ^{540}_{10}62.4 \left(1250−\dfrac{2}{3}x\right)(x−10)\,dx \\[4pt] When the reservoir is full, Lake Mead’s maximum depth is about 530 ft, and the surface of the lake is about 10 ft below the top of the dam (see the following figure). That was probably too simple of an answer to be useful in your application, though true. The tank is depicted in Figure \(\PageIndex{7}\). \end{align*}\]. We can use integration to develop a formula for calculating mass based on a density function. We assume \(ρ(x)\) is integrable. When the reservoir is at its average level, the surface of the water is about 50 ft below where it would be if the reservoir were full. In primary school, we learned how to find areas of shapes with straight sides (e.g. Then the mass of the disk is given by, \[m=\int ^r_02πxρ(x)dx. We state this result in the following theorem. Mass–Density Formula of a One-Dimensional Object, Given a thin rod oriented along the \(x\)-axis over the interval \([a,b]\), let \(ρ(x)\) denote a linear density function giving the density of the rod at a point \(x\) in the interval. Multiply the force and distance to get an estimate of the work needed to lift the layer of water. This paper discusses big data usage for various industries and sectors. \tag{step 2}\], The weight-density of water is \(62.4\)lb/ft3, so the force needed to lift each layer is approximately, \[F_i≈62.4π\left(4−\dfrac{x^∗_i}{3}\right)^2\,Δx \tag{step 3}\], Based on the diagram, the distance the water must be lifted is approximately \(x^∗_i\) feet (step 4), so the approximate work needed to lift the layer is, \[W_i≈62.4πx^∗_i\left(4−\dfrac{x^∗_i}{3}\right)^2\,Δx. In the English system, force is measured in pounds. Calculus, all content (2017 edition) Unit: Integration applications. Sum the work required to lift all the layers. Assume the top edge of the plate is at point \(x=a\) and the bottom edge of the plate is at point \(x=b\). Note that although we depict the rod with some thickness in the figures, for mathematical purposes we assume the rod is thin enough to be treated as a one-dimensional object. Orient the rod so it aligns with the \(x\)-axis, with the left end of the rod at \(x=a\) and the right end of the rod at \(x=b\) (Figure \(\PageIndex{1}\)). However, in some cases we may want to select a different reference point for \(x=0\), so we proceed with the development in the more general case. In pumping problems, the force required to lift the water to the top of the tank is the force required to overcome gravity, so it is equal to the weight of the water. The demand for big data applications is increasing due to its capability of handling and analyzing massive data. We then have. How much work is done to stretch the spring \(1\) ft from the equilibrium position? A disk and a representative washer are depicted in the following figure. Pumping problems are a little more complicated than spring problems because many of the calculations depend on the shape and size of the tank. Field Application and Integration Engineer – USA Job description. Taking the limit of this expression as \(n→∞\) gives us the exact value for work: \[ \begin{align*} W =\lim_{n→∞}\sum_{i=1}^nF(x^∗_i)Δx \\[4pt] =\int ^b_aF(x)dx. The southwest United States has been experiencing a drought, and the surface of Lake Mead is about 125 ft below where it would be if the reservoir were full. Let \(ρ(x)\) be an integrable linear density function. Lessons. So, for \(i=0,1,2,…,n\), let \(P={x_i}\) be a regular partition of the interval \([2,10]\), and for \(i=1,2,…,n\), choose an arbitrary point \(x^∗_i∈[x_{i−1},x_i]\). Then, for \(i=0,1,2,…,n\), let \(P={x_i}\) be a regular partition of the interval \([0,8]\), and for \(i=1,2,…,n\), choose an arbitrary point \(x^∗_i∈[x_{i−1},x_i]\). From the figure, we see that \(w(x)=750+2r\). ), Determine the depth and width functions, \(s(x)\) and \(w(x).\). 2. the combining of different acts so that they cooperate toward a common end; coordination. Towards a more integrated and mature IoT-enabled eHealth reality. Let’s begin with a look at calculating mass from a density function. Orient the rod so it aligns with the \(x\)-axis, with the left end of the rod at \(x=a\) and the right end of the rod at \(x=b\) (Figure \(\PageIndex{1}\)). by M. Bourne. The depth function, then, is \(s(x)=x\). \[ \begin{align*} m =\int ^r_02πxρ(x)dx \nonumber \\[4pt] =\int ^4_02πx\sqrt{x}dx=2π\int ^4_0x^{3/2}dx \nonumber \\[4pt] =2π\dfrac{2}{5}x^{5/2}∣^4_0=\dfrac{4π}{5}[32] \nonumber \\[4pt] =\dfrac{128π}{5}.\nonumber \end{align*}\]. Example \(\PageIndex{6}\): Finding Hydrostatic Force. Suppose we have a variable force \(F(x)\) that moves an object in a positive direction along the \(x\)-axis from point \(a\) to point \(b\). In this case, depth at any point is simply given by \(s(x)=x\). To calculate the work done, we partition the interval \([a,b]\) and estimate the work done over each subinterval. When the spring is at its natural length (at rest), the system is said to be at equilibrium. In today’s world, technology plays an important role in every industry as well as in our personal lives. From properties of similar triangles, we have, \[ \begin{align*} \dfrac{r_i}{12−x^∗_i} =\dfrac{4}{12} \tag{step 1} =\dfrac{1}{3} \\[4pt] 3r_i =12−x^∗_i \\[4pt] r_i =\dfrac{12−x^∗_i}{3} \\[4pt] =4−\dfrac{x^∗_i}{3}. In the English system, the unit of force is the pound and the unit of distance is the foot, so work is given in foot-pounds. Thus integration of velocity can yield position of a body in motion. This changes our depth function, \(s(x)\), and our limits of integration. Note that if \(F\) is constant, the integral evaluates to \(F⋅(b−a)=F⋅d,\) which is the formula we stated at the beginning of this section. As we did there, we use \(x^∗_i≈(x_i+x_{i−1})/2\) to approximate the average radius of the washer. Evaluating the integral, we get, \[\begin{align*} F =\int^b_aρw(x)s(x)\,dx \\[4pt] \end{align*}\], You may recall that we had an expression similar to this when we were computing volumes by shells. =−62.4\left(\dfrac{2}{3}\right)\left[\dfrac{x^3}{3}−1005x^2+253125x\right]\bigg|^{540}_{135}≈5,015,230,000\,\text{lb}=2,507,615\,\text{t}. We choose our frame of reference such that the \(x\)-axis is oriented vertically, with the downward direction being positive, and point \(x=0\) corresponding to a logical reference point.
