INSIDE TRACK IT IS UNDERSTANDABLE that you might feel a little overwhelmed looking at these lists. There are an awful lot of irregular verbs and most of them do not seem to have any relationship to one another. You can see patterns in some words, especially rhyming words—the words sleep , weep , sweep, and creep all drop the second e and add a - t when forming their past tense and past participle ( slept, wept, swept, and crept )—but these sorts of patterns usually only pertain to a handful of words. There are many words whose past tense and past participle forms end in the letters -ought — thought, fought, bought , sought —but a look at their present tense forms shows little connections between the verbs ( think, fi ght, buy, seek ).

A guess is made as to the colour of the top card, after which it is revealed and discarded. To maximise the number of correct guesses one chooses the colour corresponding to the majority of cards remaining in the deck. We determine the expected number of correct guesses with this strategy, as well as the probability of beating an opponent who uses the naive stategy of random guessing.

HOW CAN WE SPEAK MATH

HOW CAN WE SPEAK MATH

2.3.2 The trivial non-solutions One solution for “speaking mathematics” that immediately presents itself as unambiguous is to merely spell expressions as though you were typing them—character by character— on a single line. All the disambigua- tion must be done prior to spelling. In this way the problem has been reduced to that of the previously “solved” problem, namely the parsing of a programming language that is typed into a computer, and all that is needed is a mapping of sounds to keyboard elements. If the encoding language is TEX, then the appearance of almost any mathematical notation can be provided, on almost any computer system, thanks to the continuing work on maintaining TEX. If the programming language is the painfully-verbose MathML, simulating a keyboard by voice would be very time-consuming. Even with the much more concise TEX, entering β would require saying something like “dollar backslash b e t a dollar” or once you realize how close certain sounds are (a, eight) or (b, d, p) or (s, f), you might use a “military alphabet” for spelling. (In practice a military 5 spelling option uses more phonemes but is nearly error-free. It is not too difficult to learn.) Thus for a higher accuracy, you might learn to say “dollar backslash bravo echo tango able dollar”. Of course it would be easier to say “beta”!

The problem now is that too much of the ozone layer is being destroyed. Scientists suspect that certain chemicals, such as fluorocarbons, are contributing to the depletion of the ozone layer. And how do we use fluorocarbons? The most common uses are in spray cans and cooling systems. The chemical pollution from these fluorocarbons can account for some of the ozone losses that have been reported. There are, however, new studies linking the sun itself to the depletion of the ozone layer. We'll go into that new study more next time.

Probability makes the difference between facing uncertainty and cop- ing with risk. Uncertainty is a situation where we know that it is possible that things could turn out in different ways but we simply don’t know how probable each result is. Risk, on the other hand, is when we know there are different outcomes but we also have some idea of how likely each one is to occur.

Received 6 November 2007; Revised 20 February 2008; Accepted 6 May 2008 Recommended by Sergios Theodoridis A novel approach for onset detection of musical notes from audio signals is presented. In contrast to most commonly used conventional approaches, the proposed method features new detection functions constructed from the linear temporal bases that are obtained from the decomposition of musical spectra using nonnegative matrix factorization (NMF). Three forms of detection function, namely, first-order di ff erence function, psychoacoustically motivated relative di ff erence function, and constant-balanced relative di ff erence function, are considered. As the approach works directly on input data, no prior knowledge or statistical information is therefore required. Practical issues, including the choice of the factorization rank and detection robustness to instruments, are also examined experimentally. Due to the scalability issue with the generated nonnegative matrix, the proposed method is only applied to relatively short, single instrument (or voice) recordings. Numerical examples are provided to show the good performance of the proposed method, including comparisons between the three detection functions.

13. The second edition also included this C implementation along with an earlier, less capable, version of the C++ implementation we're examining here. 14. Another restriction in C++ operator overloading is that it's impossible to make up your own operators. According to Bjarne Stroustrup, this facility has been carefully considered by the standards committee and has failed of adoption due to difficulties with operator precedence and binding strength. Apparently, it was the exponentiation operator that was the deciding factor; it's the first operator that users from the numerical community usually want to define, but its mathematical properties don't match the precedence and binding rules of any of the "normal" C++ operators.

Let us look here at decision rules of the form: make the investment if ¯ y > c. An error of type one occurs if the decision rule advises you to make the investment while there is no demand for the product. This will be the case if ¯ y > c but µ ≤ 0. The probability of this error depends on the unknown parameter µ, but it is at most α = Pr[¯ y > c | µ = 0]. This maximum value of the type one error probability is called the significance level, and you, as the director of the firm, will have to decide on α depending on how tolerable it is to lose money on this venture, which presumably depends on the chances to lose money on alternative investments. It is a serious shortcoming of the classical theory of hypothesis testing that it does not provide good guidelines how α should be chosen, and how it should change with sample size. Instead, there is the tradition to choose α to be either 5% or 1% or 0.1%. Given α, a table of the cumulative standard normal distribution function allows you to find that c for which Pr[¯ y > c | µ = 0] = α.

You probably want to create a new object upon which to stroke the path before doing anything permanent to a photo: choose Window | Dockers | Objects, and then click the New Object button. Also make sure that the size of the brush and the preset for the brush along with the color (if any) is the one you want.

holds with the usual binomial coefficients on the right hand side. When r = 2, the map returns the regular binomial coefficients in the Pascal triangle. We obtain the regular Pascal pyramid if r = 3. For the cases r ≥ 4 we will refer as generalized Pascal pyramids. The main purpose of this paper is to investigate the question of unimodality in Pascal pyramids. It has already been shown that the elements laying along any ray in the Pascal triangle form unimodal sequence (see [2]). Scrutinies were made to reveal the localization of certain rays’ modes (for instance, see [5, 3, 1]). Here, in the first part we prove, similarly to Pascal triangle, that any ray crosses any Pascal pyramid is puncturing elements of an unimodal sequence. Later we concentrate only on the 3D case, where r = 3, and consider the elements x 1 + x 2 + x 3

VEXING VERBS

“Shall” and “Will” Grammar and usage experts get themselves into a lather on the finer points of this issue, and the English have an elabo- rate system that Americans are sometimes taught in school but stubbornly refuse to use. But we’ll spare you the English sys- tem here. Just keep in mind that in formal (American) speech or writing, “shall” is the correct form of “to be” for the first person (“I” or “we”) in the future and future perfect tenses. Clearly, though, “shall” is not a word you hear every day, and the negative contraction of “shall,” “shan’t” (the functional equivalent of “won’t”), sounds downright odd to American ears. A sentence such as I shan’t have any grits today, thank you would draw stares at your local diner. Most Americans simply use “will” and “won’t” in place of “shall” and “shan’t,” and it would be hard to find someone who frowns on this in ordinary conversation. However, when you wish to write or speak with the highest degree of precision and formality, use “shall” in the first person. And we shan’t trouble you any more on this matter.

Everything in Construction 2.1 is, however, a section hypergraph of one given by Kos- tochka. The easiest way to show this is by giving each vertex of the intended construction its own row in Kostochka’s construction, and filling in the empty spots such that all vertices in a row are the same color. This can be done more efficiently to start with a smaller hypergraph of Kostochka’s construction and remove fewer vertices, but usually requires removing more than one fourth of the vertices. Conversely, it can be shown that every section hypergraph of one of Kostochka’s constructions either is isomorphic to one of Construction 2.1, or else does not attain the bound of Conjecture 1.1.

Another disadvantage is that access to data sets is done on an inadequate semantic level. Applications accessing HPC data have to deal with directories, file names, and data formats instead of accessing multidimensional data in terms of simulation space or time interval. Examples of large-scale HPC data are climate-modeling simulations, cosmological experiments and atmospheric data transmitted by satellites. Such natural phenomena can be modeled as spatio-temporal array data of some specific dimensionality. Their common characteristic is that a huge amount of Multidimensional Discrete Data (MDD) has to be stored.

The inventor’s name was Elias Howe, and this simple idea enabled him to design and build the first really successful sewing machine. He was not the only famous person to find solutions to difficult problems in this way. Thomas Edison, who invented the electric light bulb, said that his best ideas came to him in his dreams. So did Albert Einstein, the great mathematician and physicist. Igor Stravinsky, the great composer, said that he ‘slept’ on his problems, and when he woke up they were solved. Few people understand the meaning of dreams. In order to do so, you have to understand what happens when you sleep. When you are awake, you notice all sorts of things and get lots of ideas without realizing it. When you are asleep, the unconscious part of your brain is active and it begins to ‘digest’ this information mentally. Sometimes it is that part of the brain that notices something important that the conscious part of your brain didn’t. The unconscious part of your mind, however, has its own logic and language. This is why the strange images in your dreams are sometimes called ‘secret messages to ourselves’.

patterns has been studied for minimum-depth banyan networks in [Kim90] with input queue- ing and in [Pat94] with shared queueing. Other ATM switch architectures have been described in which the basic banyan network is enhanced so as to include other features such as the capability of partially sharing internal buff- ers [Kim94, Wid94] or the availability of interstage link dilation without [Wid95] or with recirculation [You93]. By still using a minimum-depth routing network it is also possible to build an ATM switch [Kim93] in which a -stage distribution network precedes the -stage routing network. Both networks have the same topology (they are banyan networks) but only the latter requires internal queueing. The former network is just used to distribute the traffic entering from each port of the switch onto different input ports of the routing network. This feature can become important to provide fairness in the presence of non-uniform traffic patterns (remember that a banyan network supports only one path per inlet/outlet pair and different inlet/outlet paths share interstage links). Another proposal con- sists of parallel banyan planes one of which acting as a control plane to resolve the conflicts for all the other data planes so that multiple packet transmissions can take place without conflicts to the same output port [Won95]. Different approaches to manage the queues have also been studied. One technique consists in operating a non-FIFO queueing, analogous to the win- dowing technique described in Section 7.1.3.2, on a BRBN architecture [Su94]. Another approach, referred to as “cut-through switching”, consists in allowing a packet to cross a SE without spending a slot in the buffer if queueing is not strictly needed (for example to cope with conflicts) [Wid93].

BÁO CÁO HÓA HỌC: " AN OPTIMAL MEDIUM ACCESS CONTROL WITH PARTIAL OBSERVATIONS FOR SENSOR NETWORKS" DOCX

The main tool we use in this work is the control theory with partial information. An important quantity in this con- text is the information state, which is a probability vector that weighs the most that can be inferred about the state of the system at a certain time instance, given the system behavior at previous time instances. There are some important results in the literature dealing with related results on convergence in distribution of the information state, in which the state of a system can only be inferred from partial observations. Kaijser proved convergence in distribution of the information state for finite-state ergodic Markov chains, for the case when the chain transition matrix and the function which links the par- tial observation with the original Markov chain (the obser- vation function) satisfy some mild conditions [ 21 ]. Kaijser’s results were used by Goldsmith and Varaiya, in the context of finite-state Markov channels [ 22 ]. This convergence result is obtained as a step in computing the Shannon capacity of finite-state Markov channels, and it holds under the crucial assumption of i.i.d. inputs: a key step of that proof is shown to break down for an example of Markov inputs. This as- sumption is removed in a recent work of Sharma and Singh [ 23 ], where it is shown that for convergence in distribution, the inputs need not be i.i.d., but in turn the pair (channel input, channel state) should be drawn from an irreducible, aperiodic, and ergodic Markov chain. Their convergence re- sult is proved using the more general theory of regenerative processes. However, using directly these results in our setting does not yield the sought result of weak convergence and thus stability, as we will show that the optimal control policy is a function of the information state, whereas in previous work, inputs are independent of the state of the system. This depen- dence due to feedback control is the main di ff erence between our setup and previous work.

STEPHENS & FORAGING BEHAVIOR AND ECOLOGY CHAPTER 13 PPT

The landscape of fear should also influence patterns of mortality. Desert granivorous rodents rarely appear to be in poor body condition, and they do not seem to die from starvation. Yet food addition experiments verify that food limits their population sizes (see Brown and Ernest 2002). If the predation cost of foraging exceeds the metabolic costs of foraging, that means that these rodents usually extract much less from food patches than they could. If starvation threatens, a desert rodent can obtain food quickly by exploiting riskier patches. As an animal’s energy reserves decline, starvation becomes certain, whereas predation risk always has a probabilistic element. Better to play Russian roulette with the predators than to starve. As the energy state of the animal declines toward zero, the cost of predation also declines toward zero (as F → 0, P → 0). Hence, a starving animal should always be willing to forage in a food patch that covers its metabolic costs of foraging. If the landscape of fear varies dramatically from one location to the next, most foragers should succumb to predation rather than to starvation.

Key words: Customer Relationship Management (CRM), campaign management, customer acquisition, scoring 62.1 What is CRM? It is now a clich´e that in the days of the corner market, shopkeepers had no trouble understand- ing their customers and responding quickly to their needs. The shopkeepers would simply keep track of each customer in their heads, and would know what to do when a customer walked into the store. But today’s shopkeepers face a much more complex situation. More customers, more products, more competitors, and less time to react means that understanding your cus- tomers is now much harder to do. This is where customer relationship management (CRM) comes in. CRM lets companies design, manage, and execute strategies for interacting with cus- tomers (and potential customers). CRM can be applied to the complete customer life-cycle, from acquisition, to ongoing account management, to cross-selling, to customer retention and attrition.

A FRAMEWORK OF KNOWLEDGE MANAGEMENT SYSTEMS ISSUES AND CHALLENGES FOR THEORY AND PRACTICE

Even though normative solutions to this problem do not yet exist, we may learn from reference disciplines (e.g., such as computer science, human-computer interaction, and information science) several ways in which this problem of information overload may be tackled. Recent research suggests innovative systems and techniques for dealing with the potential information overload associated with the use of KMS. For example, Van Dyke et al. (1999) describe the use of intelligent agent technology to filter out irrelevant content and locate potentially useful conversations on Internet relay chat (IRC). The agent builds a profile of the user through a keyword-based model and recommends current chat sessions by sampling IRC channels to find current conversations that match the user’s profiles. Another line of research employs collaborative filtering methods to recommend potentially useful Usenet news posts to users (Konstan et al. 1997; Sarwar et al. 1998). The system filters messages based on users’ previous preferences and recommends Usenet news articles a user may find useful—those that other users with similar preferences have rated as being of high quality. Finally, several techniques have been developed to visualize and represent the conversational interface of synchronous and asynchronous discussion forums to express social patterns in online conversations.
