Co-ordinating content rather than producing it will become the mantra of power companies in the era of distributed generation. Utility companies, interestingly enough, serve to gain — at least in the short term — from distributed generation, although, until recently, many have fought the development. Because distributed generation is targeted to the very specific energy requirements of the end-user, it is a less costly and more efficient way of providing additional power than relying on a centralized power source. It costs an American company between US$365 and US$1,100 per kilowatt-hour to install a six-mile (ten-kilometre) power line to a three-megawatt customer. A distributed-generation system can meet the same electricity requirements at a cost of between US$400 and US$500 per kilowatt-hour.

After enough fuel cells have been leased or purchased and installed, mini–energy grids can connect urban neighbourhoods as well as rural villages into expanding energy networks. The HEW can be built organically and spread as the distributed generation becomes more widely used. The larger hydrogen fuel cells have the additional advantage of producing pure drinking water as a by-product, a not-insignificant consideration in village communities around the world where access to clean water is often a critical concern. Distributed-generation associations need to be established throughout the developing world. Civil-society organizations, co-operatives (where they exist), micro-credit lending institutions, and local governments ought to view distributed-generation energy webs as the core strategy for building sustainable, self-sufficient communities. Breaking the cycle of dependency and despair, becoming truly “empowered,” starts with access to and control over energy.

It would not have been possible to co-ordinate the increase in speed, pace, flow, density, and interactivity of commercial and social life — made possible by steam power — by relying on script or oral communication technologies. Similarly, the telegraph and, later, the telephone provided forms of communication that were fast enough to accommodate the quickened pace, flow, density, and interactivity made possible when coal gave way to an even more agile hydrocarbon, crude oil. Today, hydrogen and the new fuel-cell, distributed-generation technology are beginning to fuse with the computer and communications revolution to create a wholly new economic era. Before the distributed generation of hydrogen can be fully achieved, however, changes in the existing power grid will have to be made. That’s where the software and communications revolution fits in. Connecting thousands and then millions of fuel cells to main grids will require sophisticated dispatch and control mechanisms to route energy traffic during peak and non-peak periods.

And if we need to invest in more power plants or increased distribution capacity to meet the needs of a central city, then we should do it, because when growth takes place there we know that energy is being used more efficiently than it could be otherwise.” This is by no means a widely shared belief among environmentalists, who have generally looked upon big utilities with no more affection than they have for big cities. A growing theme in American environmentalism, in fact, has been the encouragement of “distributed generation”—the decentralizing of the production of electricity by supplementing, and in some cases circumventing, the existing power grid through the creation of smaller and more widely dispersed power-generating facilities, including ones that serve individual buildings. A prominent proponent has been Amory Lovins of RMI, who has tantaliz ingly described a future in which automobiles are replaced by hydrogen-powered “hypercars,” and homeowners generate their own electricity with photovoltaic arrays on their roofs and air-conditioner-size hydrogen-powered fuel cells—which generate electricity without combustion—and produce their own hydrogen, with in-home “hydrogen appliances” fed by natural gas.

If just one half of one percent of the U.S. demand for electricity were met by uncontrolled diesel engines, the country’s annual nitrogen oxide emissions could increase by nearly five percent.”33 Lovins and other proponents of decentralizing power production aren’t promoting diesel generators, of course, but most of the small-scale, non-grid energy production in the United States actually is diesel-powered. Large generating plants are inherently more efficient than small generators; they also do less damage to the environment per unit of output, since “fitting plants with best available control technology can be financially feasible on a large scale, but not on a small scale.” Greene and Hammerschlag are by no means dismissive of distributed generation, but their paper repeatedly demonstrates that no idea can be judged apart from its real-world context. Heating New York City apartments with individual woodstoves rather than with steam from Con Ed’s centralized steam distribution system—which supplies most buildings in Manhattan below Ninety-sixth Street, and is used to co-generate electricity—would not be a gain for the environment. The existing American power grid is antiquated, and it is vulnerable to failures like the one that shut down power in the Northeast in 2003, but breaking it apart is unlikely to be the solution, especially if doing so encourages people to live even farther from one another, thereby increasing wastefulness and environmental damage of all kinds.

Part of the fascination with distributed generation, and with the dream of hydrogen as an energy panacea, arises from our very worst impulses—the same yearnings for personal independence that lead to expressways, strip malls, and sprawl. (What is a car but distributed transportation?) The desire to produce your own power in your own basement is akin to the desire to drive yourself to work and swim in your own pool and play tennis on your own court: to be liberated from the grid is to be liberated from other people.

The Grid: The Fraying Wires Between Americans and Our Energy Future by Gretchen Bakke

People can still put solar up on their garage roofs in Hawaii, but the utility won’t connect to them, won’t pay for the electricity they generate, and won’t offer any kind of deal to homeowners on power consumed after dark. This cycle hadn’t yet reached crisis level in 2009, when Chu was listing the known woes of power companies. It’s at crisis level now. What we are bearing witness to are the early days of a variable and distributed generation revolution. Electricity is being made everywhere, by power producers of all sorts and sizes, and increasingly from uncontrollable and largely unpredictable means. And because of an awkward piece of legislation called the Energy Policy Act (1992), which laid the foundation for the deregulation of the electricity industry, in many places not only have the utilities lost control of who makes power and how and where they make it, but they have also lost the right to own power plants themselves.

And all this new small-power generation was scattered to the four winds—in the river canyons and old mines of the Sierra Nevadas, in the desert outside L.A., in the passes between San Francisco Bay and the Central Valley, even in downtown Sacramento, and almost all of it was variable. It blew with the wind, fell with the water, and warmed with the sun. The utilities quickly found themselves with a plethora of new problems. Never before had they had to deal with variable generation, never before had they had to deal with distributed generation, and never in the seventy years of their existence had they lost control over the production side of their business. At issue wasn’t that they suddenly had to integrate a massive amount of new power but that they weren’t getting to decide how much, where, or when relatively small amounts of electricity would come streaming onto their power lines. They just had to pay for it and distribute it when it got there.

For half a century the daily, quarterly, and annual running of the grid had been accomplished in meetings between the managers of various arms of a utility. Notes were taken, plans made, and later operationalized. In place of this centralized and somewhat perfunctory organizational routine the utilities now needed something like real-time flexibility. Even if the scale was initially modest, the introduction of variable, distributed generation for which they would have to pay a market price was, for the utilities, a little like aliens coming down from outer space and asking them to enter into an intergalactic energy alliance. It’s fine in theory, but unimaginable in its details. Take a simple seeming thing like paying market price. The utilities weren’t exactly clear by the late 1970s how much it actually cost to make a kilowatt-hour of electricity.

Amory Lovins, in particular, had been raising the prospect for a number of years, as had a number of other power and utility wonks. As early as 2001, the Electric Power Research Institute (EPRI) observed in its report, “Perspectives for the Future,” that distributed generation would likely evolve in much the same way the computer industry has evolved. Large mainframe computers have given way to small, geographically dispersed desktop and laptop machines that are interconnected into fully integrated, extremely flexible networks. In our industry, central-station plants will continue to play an important role, of course. But we’re increasingly going to need smaller, cleaner, widely distributed generators . . . all supported by energy storage technologies. A basic requirement for such a system will be advanced electronic controls: these will be absolutely essential for handling the tremendous traffic of information and power that such a complicated interconnection will bring.42 The IBM guys in Germany put me in touch with Guido Bartels, a Dutch national who was doing a lot of work pushing IBM’s intelligent utility network concept around the world.

In March of 2006, around the same time Kroes was out on the hustings talking up “unbundling,” Utz Claassen, the tough CEO of EnBW, the fourth largest power and utility company in Germany, invited me to Berlin to speak to his company and clients on climate change, energy security, and the transformation of the power and utility sector. Even though 45 percent of EnBW was owned by EDF of France, a company that produces 78 percent of French electricity from nuclear power, Claassen picked up on the theme of distributed generation of renewable energy.46 Three months later, he invited me to Heilbronn, Germany, to address his entire company. Some five hundred employees filled the hall. After I laid out the vision of a Third Industrial Revolution, Claassen took the podium. To the surprise of many of his employees, who had cut their teeth on conventional fossil fuels and nuclear energy and were used to a centralized, top-down flow of power, Claassen said the energy market was changing and so was EnBW.

The late Hermann Scheer, the chairman of the World Council for Renewable Energy and a member of the German Parliament, argued that transporting solar energy over vast distances is inefficient and a waste of money, and that Africa should be focusing its efforts on local generation of renewable energies instead. Greenpeace comes down in the middle on the debate. Sven Teske, Greenpeace’s international renewable energy director, supports Desertec, but with the qualification that it should be developed alongside local renewable energy generation initiatives across the continent.22 The struggle over centralized versus distributed generation of renewable energy is intensifying around the world. For my part, while I don’t oppose some centralized applications of solar, wind, hydro, geothermal, and biomass power, they are likely to make up a small portion of the renewable energy generated to power a Third Industrial Revolution economy. The reality is that renewable energies are, by nature, universally distributed, and the new, distributed communication technologies make it possible to harness and store these energies locally and distribute them across intelligent utility networks that span entire continents.

When electricity generation, transmission, and distribution losses are added in, the overall efficiency of the same light bulb at converting the primary energy from the power plant to the actual light that you use in your home has dwindled to just three percent. One way of addressing the inefficiency of power transmission and distribution is through what power companies call “distributed generation.” Distributed generation is where electricity is fed into power lines by small, scattered power plants such as wind mills, solar electric arrays on roof tops, small-scale hydro power, methane captured at farms or landfills, or fossil fuel powered turbines. The energy from these decentralized power sources tends to be used on-site by whoever is producing it, with the excess going out onto the grid for everyone else. Energy security analysts think distributed generation is preferable because reducing the demand on a single, central power plant makes widespread power interruptions less likely. Another way to increase power plant efficiency is by way of co-generation (cogen) also known as combined heat and power (CHP).

This is a modification of the Box-Muller generator designed to avoid the calculation of sin or cos. Here we generate a point (Z1 , Z2 )from the uniform distribution on the unit circle by rejection, generating the point initially from the square −1 · z1 · 1, −1 · z2 · 1 and accepting it when it falls in the unit circle or if z12 + z22 · 1. Now suppose that the points (Z1 , Z2 ) is uniformly distributed GENERATING RANDOM NUMBERS FROM NON-UNIFORM CONTINUOUS DISTRIBUTIONS131 inside the unit circle. Then for r > 0, q P [ −2 log(Z12 + Z22 ) · r] = P [Z12 + Z22 ≥ exp(−r2 /2)] 1 − area of a circle of radius exp(−r2 /2) area of a circle of radius 1 = 1 − e−r 2 /2 . This is exactly the same cumulative distribution function as that of the random variable R in Theorem 21. It follows that we can replace R2 by −2log(Z12 +Z22 ).

Of course we can always begin the Markov chain in some arbitrary initial state and run it waiting for Hele to freeze over (it does happen since Helle is in Devon) until we are quite sure that the chain has essentially reachedequilibrium, and then use a subsequent portion of this chain, discarding this initial period, sometimes referred to as the “initial transient”. Clearly this is often not a very efficient method, particularly in cases in which the chain mixes or forgets its past very slowly for in this case the required initial transient is long. On the other hand if we shortened it, we run the risk of introducing bias into our simulations because the distribution generated is too far from the equilibrium distribution π. There are a number of solutions to this problem proposed in a burgeoning literature. Here we limit ourselves to a few of the simpler methods. 178 CHAPTER 3. BASIC MONTE CARLO METHODS Metropolis-Hastings Algorithm The Metropolis-Hastings Algorithm is a method for generating random variables from a distribution π that applies even in the case of an infinite number of states or a continuous distribution π.

Note that there is no need to reposition each rule’s return distribution to be centered over zero as is done with WRC because it assumes that all rules have an expected return of zero. In contrast, the MC sampling distribution’s mean is the expected return of a useless rule in a data-mining venture. If, after randomly assigning rule values to market returns, the sampling distribution is situated at a value greater than zero, so be it. pvalues can be computed directly from the MC generated sampling distribution, just as they would be with a sampling distribution generated by alternative methods. The p-value is the area in the right tail of the distribution that lies at or beyond the back-tested rule’s mean return. A limitation of the MC method compared to WRC is that it cannot be used to generate confidence intervals because it does not test a hypothesis about the rule’s mean return. MC’s null hypothesis is simply that all rules tested have output values that are randomly correlated with future market behavior.

They receive information about the exact location of the outage to save time. In addition, the analytics can be shared with out call center. The customers don’t even have to call us. We can call them and say, “A pole in your area has been damaged. Crews are on site and repair should be complete soon.” All of that is coming in the very near future. And the other thing is that in the future there will be a lot more distributed generation. For example, there may be customers that are generating their own power through solar panels. We’re putting smart meters on everyone’s home so we can tell them—in the future—how much electricity they’re using at different times of the day. If customers want to be more efficient, these smart meters have the intelligence to tell them when they’re using a lot and determine what it is that’s driving usage up.

X ∼ GHd (λ, χ , ψ, μ, , γ ): 1 φX (t) = E(E(exp(it X )|W )) = E exp it μ + W t γ − W t t 2 t t − it γ , = exp(it μ)H 2 (θ) = E(e−θ W ) is the Laplace transform of the density function h of W . where H With the help of the characteristic function, we can show that GH distributions are closed under linear transformations. PROPOSITION 7.5 If X ∼ GHd (λ, χ , ψ, μ, , γ ) and Y = BX + b, where B ∈ Rk×d and b ∈ Rk , then Y ∼ GHk (λ, χ , ψ, Bμ + b, BB , Bγ ). Proof . i t (BX +b) φY (t) = E(e it b )=e i t (Bμ+b) φX (B t) = e H t BB t − it Bγ . 2 This proposition shows that linear transformations of GH distributions remain in the class of GH distributions generated by the same GIG distribution N − (λ, χ , ψ), which is a useful property in portfolio management. COROLLARY 7.6 If B = ω = (ω1 , . . . , ωd ) and b = 0, then y = ω X is a one-dimensional GH distribution, and y ∼ GH1 (λ, χ , ψ, ω μ, ω ω, ω γ ). More specifically, the margins of X is X i ∼ GH1 (λ, χ , ψ, μi , ii , γi ). 170 CHAPTER 7 Risk Forecasting with Multiple Timescales This corollary shows that the method used in portfolio risk management based on multivariate normal distribution is also applicable to GH distribution.

X are E(X ) = μ + γ cov(X ) = ν , ν−2 2ν 2 ν + γγ , ν −2 (ν − 2)2 (ν − 4) (7.17) (7.18) where the covariance matrix is only defined when ν > 4. Moreover, when γ = 0, the skewed t distribution degenerates into the Student t distribution. As implied by its name, an inverse gamma r.v. is the inverse of a gamma r.v. Together with the mean–variance mixture definition, we can generate a skewed t r.v. accordingly. 171 7.2 The Skewed t Distributions ALGORITHM 7.8 1. 2. 3. 4. Simulation of the Skewed t Distribution. Generate Y from a Gamma( ν2 , ν2 ) distribution. Set W = Y −1 . By definition, W ∼ InverseGamma( ν2 , ν2 ). Generate a d-dimensional normal random vector Z ∼ Nd (0, Id ). Let √ X = μ + W γ + W AZ . Then X ∼ SkewT (ν, μ, , γ ). Other subfamilies of the GH distribution include Hyperbolic Distributions If λ = (d + 1)/2, we refer to the distribution as a d-dimensional hyperbolic distribution. If λ = 1, we get the multivariate distribution whose univariate margins are one-dimensional hyperbolic distributions.

One recent study suggests that finite moments for daily equity returns exist only up to order 3 and for daily trading volume only up to order 1.5 (Gabaix et al. 2003). These findings, if correct, impose substantive restrictions on the sorts of models that can sensibly be estimated. Can safely we ignore this evidence? After all, why should one be concerned about convergence failures in infinite samples? The answer is that whatever one’s beliefs about the properties of the distribution generating the data, the existence of extreme values in finite samples is an irrefutable fact leading to many practical consequences. Sample estimates may be dominated by a few extreme values. Increasing sample size does not increase precision as fast we’d expect. Estimated parameters are sensitive to model specification. Finally, and most disturbingly in trading applications, conclusions drawn from the model are fragile.

The Frasers’ data suggests that stimulating millions of green energy experiments on urban rooftops is a more economically viable method of creating a green energy economy than building large centralized wind and solar farms. “We need a new paradigm,” said Gordon. “We can’t go on borrowing the same underlying assumptions and design traditions that underpin the industrial age model of power generation.” Naturally, the utility companies—who have little to gain from distributed generation—are not particularly enthralled with the Frasers’ arguments.19 Taken to its logical conclusion, distributed generation would unleash massive disruption and potentially make redundant a large part of what power utilities do today. Rather than selling power—a majority of which would be produced locally by homeowners and businesses—the core of the industry would shift to selling green energy installations and energy services like smart grid apps that help households and businesses save money.

Contributions and accumu­ lated earnings under such plans are not taxed until they are distributed to the employee. This is advan­tageous because employees generally will be in a lower tax bracket at retirement age, and the funds, while they are held in trust, can be invested and allowed to accumulate with no chapter 4 | corporate taxation | 89 tax due on investment income or gains prior to their distribution. Generally speaking, there are two basic types of pension plans: defined-contribution and defined-benefit plans (there are some hybrid types as well). A defined-contribution plan guarantees a specified yearly contribution of no more than 25% of an employee’s annual salary to each employee. A defined-benefit plan guarantees a specified benefit upon retirement, which can be as large as 100% of an employee’s annual pay during his or her highest-paid years.

The distribution of capital ownership (and of income from capital) is always more concentrated than the distribution of income from labor. Two points need to be clarified at once. First, we find this regularity in all countries in all periods for which data are available, without exception, and the magnitude of the phenomenon is always quite striking. To give a preliminary idea of the order of magnitude in question, the upper 10 percent of the labor income distribution generally receives 25–30 percent of total labor income, whereas the top 10 percent of the capital income distribution always owns more than 50 percent of all wealth (and in some societies as much as 90 percent). Even more strikingly, perhaps, the bottom 50 percent of the wage distribution always receives a significant share of total labor income (generally between one-quarter and one-third, or approximately as much as the top 10 percent), whereas the bottom 50 percent of the wealth distribution owns nothing at all, or almost nothing (always less than 10 percent and generally less than 5 percent of total wealth, or one-tenth as much as the wealthiest 10 percent).

It is as if an official government report on inequalities in France in 1789 deliberately ignored everything above the ninetieth percentile—a group 5 to 10 times larger than the entire aristocracy of the day—on the grounds that it was too complex to say anything about. Such a chaste approach is all the more regrettable in that it inevitably feeds the wildest fantasies and tends to discredit official statistics and statisticians rather than calm social tensions. Conversely, interdecile ratios are sometimes quite high for largely artificial reasons. Take the distribution of capital ownership, for example: the bottom 50 percent of the distribution generally own next to nothing. Depending on how small fortunes are measured—for example, whether or not durable goods and debts are counted—one can come up with apparently quite different evaluations of exactly where the tenth percentile of the wealth hierarchy lies: for the same underlying social reality, one might put it at 100 euros, 1,000 euros, or even 10,000 euros, which in the end isn’t all that different but can lead to very different interdecile ratios, depending on the country and the period, even though the bottom half of the wealth distribution owns less than 5 percent of total wealth.

Create Your Own Standardized Score For fun, you can create your own standardized score distribution with any mean and standard deviation you wish. Don't like your SAT score of 350? Transform it into a score within a distribution of your choosing. Imagine, for example, that you'd prefer a distribution with a mean of 752,365 and a standard deviation of 216,456 (and who wouldn't?). Let's call this distribution the Frey Score Distribution. Generalizing the T score formula, you could transform your SAT score of 350 into a Frey score. Remember, you have to start with the z score for an SAT score of 350: and then transform it into a Frey score: Now, doesn't a score of 427,681 sound better than a score of 350? Because you know the mean of the Frey distribution, the interpretation of both scores is the same; they are still below average, and they are still 11/2 standard deviations below the mean.

Fully in keeping with the scientific ethos of the era, young members of the New Communalist wing of the counterculture, along with many in the New Left, imagined themselves as part of a massive, geographically distributed, generational experiment. The world was their laboratory; in it they could play both scientist and subject, exploring their minds and their bodies, their relationships to one another, and the nature of politics, commerce, community, and the state. Small-scale technologies would serve them in this work. Stereo gear, slide projectors, strobe lights, and, of course, LSD all had the power to transform the mind-set of an individual and to link him or her through invisible “vibes” to others.

I was always midway between the frequentist and Bayesian camps. People who think like me call ourselves data analysts, and we like nonparametric or distribution-free methods. We use a lot of rough tools, like jackknifes, bootstraps, cross-tabulations, and visualizations. We like to let the data speak to us instead of trying to fit it in a preconceived model, and we like simple methods that do not require strong assumptions about either the distribution generating the data or our prior knowledge. So on my own time, for my dissertation, I was trying a third approach to the conditional heteroskedasticity problem. A popular technique among data analysts is resampling. To predict the future, you string together randomly selected days from the past—with replacement, meaning you can pick the same past day more than once. You do this many times to generate a distribution of possible future outcomes.

• There must be a way for an individual to prevent information about him that was obtained for one purpose from being used or made available for other purposes without his consent. • There must be a way for an individual to correct or amend a record of identifiable information about him. • Any organization creating, maintaining, using, or disseminating records of identifiable personal data must assure the reliability of the data for their intended use and must take precautions to prevent misuse of the data.101 These recommendations present a tall order for distributed, generative systems. It may seem clear that the existence of personal data record-keeping systems ought not to be kept secret, but this issue was easier to address in 1973, when such systems were typically large consumer credit databases or government dossiers about citizens, which could more readily be disclosed and advertised by the relevant parties. It is harder to apply the antisecrecy maxim to distributed personal information databases.

Source: GridPoint (www.gridpoint.com). 334 Nerds on Wall Str eet GridPoint explains how its simple blue box on the wall addresses all the key issues in our electricity future: The platform applies information technology to the electric grid to enable distributed energy resources to perform the same as central-station generation. During peak periods, utilities efficiently balance supply and demand by discharging stored power from distributed generation assets or reducing customers’ non-essential loads through demand response programs. Additionally, utilities effectively optimize baseload generation assets and relieve stress on transmission and distribution systems. The platform enables utilities to deploy proven technologies, (e.g., load control devices and advanced batteries) while creating a practical path for integrating new technologies (e.g., plug-in hybrid electric vehicles [PHEVs] and fuel cells).

You can use the command in two ways: you can see what the current settings are and you can also alter these settings. If you type the command without any instructions (that is, just a pair of parentheses) you see the current settings: > RNGkind() [1] "Mersenne-Twister" "Inversion" Two items are listed. The first is the standard number generator and the second is the one used for normal distribution generation. To alter these, use the kind = and normal.kind = instructions along with a text string giving the algorithm you require; this can be abbreviated. The following example alters the algorithms and then resets them: > RNGkind(kind = 'Super', normal.kind = 'Box') > RNGkind() [1] "Super-Duper" "Box-Muller" > RNGkind('default') > RNGkind() [1] "Mersenne-Twister" "Box-Muller" > RNGkind('default', 'default') > RNGkind() [1] "Mersenne-Twister" "Inversion" Here you first alter both kinds of algorithm.

Merfeld: I think the whole stationary grid space is exciting, underdeveloped, and in the early percolation stages of evolving. There’s a lot of excitement about this space, and I think it could be an opportunity like the hybridization of transportation to get better fuel economy. Applying that same concept around how we do power generation for electricity is going to be pretty exciting. Whether it’s distributed generation, whether it’s allowing the increased penetration of renewables, whether it changes in the way we actually think, whether it changes the models that we can use to envision how you make and sell electricity, I think energy storage has the promise to change that whole space. Stern: This technology is fairly macro. Do you see it getting into a micro level? I mean are there products that you will eventually make that the individual will use?

Tolnar: The distributed energy resources now are monitored. What do I do with those? I manage those. So now I know that I've got 100 megawatts of storage in a given area. I've got 30 megawatts of thermal energy through ice that I froze that evening and it is ready to melt as needed so I don't have to use an air conditioning compressor. Then I've got a certain amount of distributed resources through distributed generation sources. That may be solar, it may be wind, it may be backup generation, and it may be some other form of biomass. Now … we can't control the sun. We can't control the wind—yet. But what we can do through tight coupling of the other resources is make a more predictable supply and demand curve, because the goal is predictability. Central generation is not going to go away anytime soon. What we have to do is make its life last a heck of a lot longer.

While there has been a tremendous surge of interest in sustainability, and some universities now have a sustainability officer leading the charge to look for green solutions, some areas of academia have been slow to catch on. The courses that many teach offer no sustainable solutions for the world their graduates will find. They are still part of the problem. Aspiring mechanical engineers still learn everything about internal combustion engines and not enough about fuel cells. Budding electrical engineers are still taught all about coal-fired central power plants, and not enough about distributed generating capacity from clean, renewable resources like the wind and the sun (or the local, methane-rich garbage dump!). Ceramics engineers still learn the traditional, abusive, heat-beat-treat methods that, quite literally, go back a thousand years or more. Meanwhile, they overlook the abalone’s natural nanostructural methods that use self-organized proteins and minerals dissolved in cold seawater to produce a ceramic product—mother-of-pearl nacre—that is superior to any man-made ceramic.

If managed futures can provide downside protection, we would expect the average monthly downside return to be smaller than that observed for our initial stock/bond portfolio. Once again, we build a blended portfolio of 55 percent U.S. stocks, 35 percent U.S. treasury bonds, and 10 percent CTA strategy. We then develop a frequency distribution of monthly returns over the period 1990 to 2000. In Table 11.3 we present the results from the return distribution generated by this CTA-blended portfolio for each CTA strategy. For example, for CTA agriculture, the average downside return is −1.81 percent. This is an improvement of 26 basis points over the average downside return observed with the stock/bond portfolio. The number of downside months with CTA agriculture managed futures added to the portfolio increased by one month to 43. Unfortunately, some upside potential was sacrificed, as the expected monthly return of the investment portfolio declined from 0.91 percent to 0.88 percent when CTA agriculture managed futures are added.

On his thirty-six-acre spread, he had laid out whole streets, each lined with wooden poles topped with glass lanterns, inside each of which was an incandescent bulb. Imaginary houses, designed to look like those in lower Manhattan, were also staked out, and they were lighted, too, and this whole unreal New York City was connected to an array of batteries with feeder cables (which took the power to the streets), mains wires (which took it into the houses), and service wires (which went to the individual house lamps). Edison’s basic plan for electric distribution—generator, feeder, mains, service—remains today the standard model for all distribution everywhere. Once he threw the switches, his display burst into a frenzy of glitter. It immediately and mightily impressed the city’s Blue Book visitors. The Vanderbilts, prominent from their railroading fortune, were the first to back Edison’s efforts. Then a portfolio of barons—J. P. Morgan, Baron Rothschild, and Henry Villard among them—followed suit, commingling between them sufficient funds to allow Edison to forge ahead.

However, a complete return to that model would be folly, for it would rob both the grid and micropower plants of the chance to sell power when the other is in distress. Rather, the grid will be transformed into a digital network capable of handling complex, multi-directional flows of power. Micropower and megapower will then work together. abb foresees the emergence of “microgrids” made up of all sorts of distributed generators, including fuel cells (which combine hydrogen and oxygen to produce electricity cleanly), wind and solar power. The University of California at Irvine is developing one, as are some firms in Germany. “Virtual utilities” would then aggregate the micropower from various sources in real time – and sell it to the grid. Energy-storage devices will be increasingly important too. Electricity, almost uniquely among commodities, cannot be stored efficiently (except as water in hydroelectric dams).

In other words, the $60,000 distribution is tax free to the extent that the depreciation deduction of $80,000 exceeds the amortization of $40,000—namely $40,000. If the amortization payment were increased to $50,000, only $30,000 of the distribution would be tax free ($80,000 − $50,000). Real estate investment trusts (REITs). The tax treatment of real estate investment trusts resembles that of open-end mutual funds. Distributions generally are reported to the investors on Form 1099-DIV as dividend income. However, distributions generally do not qualify for the reduced tax rate on qualified dividends (4.1). A distribution qualifies for the reduced rate only to the extent it represents previously taxed undistributed income or qualifying dividends received by the REIT (from stock investments) that are passed through to the investors. Capital gain distributions reported on Form 1099-DIV must be reported as long-term capital gains regardless of how long the REIT shares have been held (4.4).

Any expenses taken into account when figuring an American Opportunity credit or Lifetime Learning credit further reduce qualified expenses. The balance of qualifying expenses after subtracting tax-free educational assistance and credit-related expenses is the beneficiary’s adjusted qualified educational expenses. The Example below shows how the taxable portion of the distribution is determined when the total distribution exceeds the adjusted qualified education expenses. Additional tax on taxable distributions. Generally, a taxable distribution is subject to a 10% additional tax, which is figured on Form 5329. However, the 10% additional tax does not apply to distributions that are: (1) made to a beneficiary (or to the estate of the designated beneficiary) on or after the death of the designated beneficiary, (2) made because the designated beneficiary is disabled, (3) taxable because the designated beneficiary received a tax-free scholarship or educational assistance allowance that equals or exceeds the distribution, or (4) taxable only because the qualified ESA education expenses were reduced by expenses used in figuring an American Opportunity or Lifetime Learning credit.

The smart intergrid will not only give end users more power over their energy choices, but it also creates new energy efficiencies in the distribution of electricity. The intergrid makes possible a broad redistribution of power. Today’s centralized, top-down flow of energy becomes increasingly obsolete. In the new era, businesses, municipalities, and homeowners become the producers as well as the consumers of their own energy—what is referred to as “distributed generation.” The distributed smart grid also provides the essential infrastructure for making the transition from the oil-powered internal combustion engine to electric and hydrogen fuel-cell plug-in vehicles. Electric plug-in and hydrogen-powered fuel-cell vehicles are also “power stations on wheels” with a generating capacity of twenty or more kilowatts. Since the average car, bus, and truck is parked much of the time, it can be plugged in during nonuse hours to the home, office, or main interactive electricity network, providing premium electricity back to the grid.

First-order interface design produces the conditions of interassemblage between people, things, or places—making it good, smart, fast, flexible, sustainable, and so on.

In Cardiff, for example, he was accused of trespassing, which led to an open debate in court about whether a stall was “as sacred as an Englishman’s private house.” “That one spot is,” it was affirmed. People with real addresses – shopkeepers, coffeehouse men, publicans, and so on – were an altogether more serious matter. Their fixed premises meant they could often act as local centers of distribution. Generally, hawkers would be supplied from some such house, pub, or other outlet, with the actual warehouse being a small distance away down a back street. Two examples stand out as notable. One was the Manchester shop of a young man called by the press “Himie Cohen,” where Preston found thirty hawkers collecting piracies to sell (some of them escaped out of a window). He also seized a memo book detailing average takings of £12 to £24 per week – an indication of the proceeds to be expected from a middleoftheroad piracy outfit.

dj This vision of decentralized energy is hardly a radical one and goes all the way back to Thomas Edison, who strongly favored electricity supply through a decentralized DC network. His DC “micropower” systems failed because the technology was unreliable and expensive. Edison had to watch a couple of his DC plants literally go up in flames before he gave up on the idea. dk I have chaired two committees on IT in the power sector, and the second one recommended having such “Smart Grids” that can deal with distributed generation and multiple renewable sources.

To tackle the problem demonstrated in Example 12.12, we can assume that the normal data objects are generated by a normal distribution, or a mixture of normal distributions, whereas the outliers are generated by another distribution. Heuristically, we can add constraints on the distribution that is generating outliers. For example, it is reasonable to assume that this distribution has a larger variance if the outliers are distributed in a larger area. Technically, we can assign , where k is a user-specified parameter and σ is the standard deviation of the normal distribution generating the normal data. Again, the EM algorithm can be used to learn the parameters. 12.3.2. Nonparametric Methods In nonparametric methods for outlier detection, the model of “normal data” is learned from the input data, rather than assuming one a priori. Nonparametric methods often make fewer assumptions about the data, and thus can be applicable in more scenarios. Outlier detection using a histogram AllElectronics records the purchase amount for every customer transaction.

In contrast, General Mills substantially reduced costs in Pillsbury’s purchasing, manufacturing, and distribution, because the two companies’ operations duplicated significant costs. On the revenue side, General Mills boosted Pillsbury’s revenues by introducing Pillsbury products to schools in the United States where General Mills already had a strong presence. And the synergies worked both ways: for instance, Pillsbury’s refrigerated trucks were used to distribute General Mills’ new line of refrigerated meals. Pillsbury represented value in at least two ways at the time of the sale: its value to General Mills and its value to Diageo. For General Mills to consider the deal attractive, Pillsbury’s worth under General Mills’ ownership had to be greater than the $10.4 billion purchase price. For Diageo to consider the deal attractive, General Mills’ offer had to represent more than the value Diageo expected to create from Pillsbury in the future.

On the Jordanian front the war had essentially been won. Only three cities had not yet been captured—Nablus, Hebron, and Jericho—but they were encircled. The air force had shot down twenty-three more planes, about half Egyptian and half Iraqi, and had lost five of its own. The number of Israeli dead had reached 460: 225 in the south and 235 on the West Bank.46 The commander of Southern Command distributed General Order No. 2 among his troops: “Never before have so few pilots destroyed so many aircraft in such a short time.” He urged them to keep up the good work: “Follow the enemy and strike him down, hit him again and again, until he is defeated by the sword of the fighters of the Southern Command,” he wrote.47 CHAPTER 14 DAY THREE 1. TEARS: “I’M TOUCHING THE KOTEL!” The sun rose large over the low hilltops in the east, wrote Yehoshua Bar-Dayan on the morning of his third day of war, Wednesday, June 7.
