Should I?This piece originated from my days in Boston in the mid 1980s as a graduate student and as part of the New England Conservatory Honors Jazz Ensemble, which performed music from across many wide ranging styles. Good interaction amongst the rhythm section is crucial. If you have a guitarist or electric keyboard/s in the rhythm section, feel free to incorporate a range of electronic effects in order to change textures. Changes in dynamics within the rhythm section is of prime importance. Think of music from the Miles Davis groups and albums of the late 1960s and early 70s such as In a Silent Way, Bitches Brew, and On the Corner. This Jazz-Rock piece has plenty of room to stretch out over the two key centers of A7 (alt) and Eb minor. The melody should be played with a straight eighth-note feel with attention to the accented (>) and capped (^) notes at Letters A and C. Watch the change in dynamics starting one beat before Letter D until the end of the form. At Letters B, F, F1 (the bridge of the form), the rhythm section shifts to a 12/8 African feel. The interlude at Letter I happens only at the end of each solo form. Note - The solo/ensemble interlude at Letter E1 follows a 16, 10 (8+2), 16 bar form which is different than the solo form at E-H. The interlude at Letter E1 was written to assist soloists with material to play or draw from during solos. Should I? can be heard on Beauty and the Blues (MMC2045J) with jazz greats Billy Hart, Rufus Reid and Tom McKinley.Nombre de pages :44

Wicked-smart Briana Ruiz and Jack McCullough meet in grad school at the University of Texas at Austin. They find themselves conflicted about the current state of economic theory, as well as with each other. There is a disconnect between economics and ecosystems that continues to be unresolved by theory and by public policy discussions at the highest levels.Nearing graduation, Briana must decide whether to accept an offer from Parkus Corporation, a company that seems leading edge, but may be engaging in questionable environmental practices. She begins work on a mathematical model - an entropy model which incorporates variables economists have failed to consider - in order to make more accurate predictions.The first wave of environmental anomalies begins, which briefly increases public awareness about the unsustainability of lifestyles in the United States and the developed world.Years later, after completing their doctorates, Briana and Jack secure federal government research positions tracking environmental incidents and establishing the first comprehensive system of national accounts to fully allocate costs across industry sectors.Briana’s work brings her and Jack directly into conflict with the Federal Reserve, the White House and the economics’ establishment. Once again, environmental anomalies begin to reoccur throughout the world. This time, as they increase in frequency, the stakes get higher. The clash between economics and ecosystems, between economic theory and public policy are taking place in real time, and the stage is set for the next great transition of the human species - whether for good or ill.Time is running out, and Washington doesn’t want to hear about it, despite the fact that the bubbles keep getting bigger, and the crashes keep getting worse. As financial systems and ecosystems approach a simultaneous peak, will anyone listen before it’s too late to stop the collapse? 1. Language: English. Narrator: Kae Denino.

Advanced Calculus
28,99 € *
ggf. zzgl. Versand

With a fresh geometric approach that incorporates more than 250 illustrations, this textbook sets itself apart from all others in advanced calculus. Besides the classical capstones--the change of variables formula, implicit and inverse function theorems, the integral theorems of Gauss and Stokes--the text treats other important topics in differential analysis, such as Morse´s lemma and the Poincaré lemma. The ideas behind most topics can be understood with just two or three variables. The book incorporates modern computational tools to give visualization real power. Using 2D and 3D graphics, the book offers new insights into fundamental elements of the calculus of differentiable maps. The geometric theme continues with an analysis of the physical meaning of the divergence and the curl at a level of detail not found in other advanced calculus books. This is a textbook for undergraduates and graduate students in mathematics, the physical sciences, and economics. Prerequisites are an introduction to linear algebra and multivariable calculus. There is enough material for a year-long course on advanced calculus and for a variety of semester courses--including topics in geometry. The measured pace of the book, with its extensive examples and illustrations, make it especially suitable for independent study.

It is well known that compression, in its basic form, tends to remove high frequencies from any material with a wide bandwidth. This is because material usually has less energy at high frequencies than it does at low frequencies and since single band compressors are not frequency conscious, the ´highs´ are attenuated together with the ´lows´. Using a slow attack time improves matters to some extent, but signals containing many harmonics (eg: vocals, strings and brass) or dynamic signals with a powerful ´leading edge´ (eg: piano, kick and snare drum) tend to lose some clarity which often requires further audio processing. It is a fact that many engineers who would like to use a compressor in a particular application, avoid doing so because they feel that the ´sound loses something´. The DL251 ´Spectral Compressor´, incorporates a variable ´Dynamic Spectral Enhancement´ (D.S.E.) section which eliminates the problems associated with full band compressors by restoring the high frequency energy lost during the full band compression process. This enhancement circuitry is extremely effective where compression and limiting are employed for broadcast transmission, or across complete mixes in a stereo mixdown situation. ´Dynamic Spectral Enhancement´ has many creative applications when recording individual components at the multi-track stage, particularly on such programme as acoustic guitar, piano, brass and vocals.Facilities available on the DL251 include: -> Compressor : The compressor section can be switched to provide either HARD or SOFT knee compression In both the HARD and SOFT modes a Ratio control is available In the S0FT mode the ratio increases gradually over a 10dB input level range until it reaches the ratio set on the front panel control, thus achieving a more natural sounding compression. Selectable manual or automatic Attack and Release times dramatically extend the application range and user scope of the DL251. Selecting the ´Auto´ mode removes the need for manual adjustment and is particularly valuable when the programme being treated does not have predictable or consistent dynamics, such as on complete mixes, vocals or ´slapped and pulled´ bass guitar. Under manual control the wide range of adjustment available gives the user the ability to create dynamic effects as well as normal compression. -> Enhance Level : A variable Enhance control can be used to ´dynamically´ boost any high frequency energy lost during the full band compression process and has sufficient range to add additional ´Spectral Energy´ to the programme material for creative processing. When no compression is taking place, the ´Dynamic Spectral Enhancement´ circuitry is inoperative and so no change is made to the signal. However, as the signal level rises to the point where gain reduction is taking place, the Enhancement system ´kicks in´ applying dynamic boost which is directly related to the amount of gain reduction taking place. A front panel switch offers an instant A/B comparison of this feature and a green LED indicates the amount of enhancement taking place. -> Metering : Comprehensive bar graph displays give ´at a glance´ indications of gain reduction, and input/output signal level Gain reduction from 1 dB to -30dB is shown simultaneously with signal level from 20dB to + 15dB Other single LEDs indicate function status of Hard/ Soft compression, Auto Attack/ Release, Side chain monitoring, Bypass, Enhancement, Peak Limiting, Stereo Linking and Power on. -> Side Chain Listen : A front panel push button with LED status enables the monitoring of any external processing applied to the side chain access connections on the rear panel. -> Bypass : A fully balanced hard wire bypass connects the input directly to the output allowing signal to pass through the unit with no power applied. In bypass mode the output level bar graph displays the Input signal. -> Stereo Link : When processing stereo signals, linking should be used to prevent image shifting. This facility ties both channels together. Using channel 1 (Left) as the master channel removes the need to duplicate control settings for both channels. A rear panel switch allows the selection of ´Peak´ or ´Average´ stereo signal detection. -> Peak Level : ´Zero Response Time´, ´Zero Overshoot´ circuitry provides an absolute limit to the peak level of the output signal, adjustable from 0dB to +16dB above system level When set to the required level, any excessive peaks will be...

ggf. zzgl. Versand

The application of geometric algebra to the engineering sciences is a young, active subject of research. The promise of this field is that the mathematical structure of geometric algebra together with its descriptive power will result in intuitive and more robust algorithms. This book examines all aspects essential for a successful application of geometric algebra: the theoretical foundations, the representation of geometric constraints, and the numerical estimation from uncertain data. Formally, the book consists of two parts: theoretical foundations and applications. The first part includes chapters on random variables in geometric algebra, linear estimation methods that incorporate the uncertainty of algebraic elements, and the representation of geometry in Euclidean, projective, conformal and conic space. The second part is dedicated to applications of geometric algebra, which include uncertain geometry and transformations, a generalized camera model, and pose estimation. Graduate students, scientists, researchers and practitioners will benefit from this book. The examples given in the text are mostly recent research results, so practitioners can see how to apply geometric algebra to real tasks, while researchers note starting points for future investigations. Students will profit from the detailed introduction to geometric algebra, while the text is supported by the author´s visualization software, CLUCalc, freely available online, and a website that includes downloadable exercises, slides and tutorials.

ggf. zzgl. Versand

A complete and up-to-date survey of microeconometric methods available in Stata, Microeconometrics Using Stata, Revised Edition is an outstanding introduction to microeconometrics and how to execute microeconometric research using Stata. It covers topics left out of most microeconometrics textbooks and omitted from basic introductions to Stata. This revised edition has been updated to reflect the new features available in Stata 11 that are useful to microeconomists. Instead of using mfx and the user-written margeff commands, the authors employ the new margins command, emphasizing both marginal effects at the means and average marginal effects. They also replace the xi command with factor variables, which allow you to specify indicator variables and interaction effects. Along with several new examples, this edition presents the new gmm command for generalized method of moments and nonlinear instrumental-variables estimation. In addition, the chapter on maximum likelihood estimation incorporates enhancements made to ml in Stata 11. Throughout the book, the authors use simulation methods to illustrate features of the estimators and tests described and provide an in-depth Stata example for each topic discussed. They also show how to use Stata´s programming features to implement methods for which Stata does not have a specific command. The unique combination of topics, intuitive introductions to methods, and detailed illustrations of Stata examples make this book an invaluable, hands-on addition to the library of anyone who uses microeconometric methods.

The MX40 Punch Gate is a high performance, simple to use 1U four channel noise gate that offers the same extraordinary sonic character, ingenuity, and high technical specification that have made Drawmer the world standard in gating technology. The MX40 is the first low cost, truly professional gate to offer the features and performance typical of much more expensive noise gates.The MX40 is the first Drawmer product to feature proprietary ´Peak PunchTM´ circuitry which adds unique dynamic enhancement to the leading edge of percussive material, adding true ´punch´ to the performance. The MX40 also includes Drawmer´s Frequency Conscious System (first introduced with the DS201 Dual Gate), which ´tunes´ the gate to react only to a specific frequency band, dramatically improving gate operation. The MX40 packs four channels of high power Drawmer gating into a single rack space, with controls and indicators designed to make set up faster and easier.The Drawmer MX40 Punch Gate offers improved signal definition in complex mixes by isolating desired signal from unwanted background noise. It is especially important in sound reinforcement and the recording of short term sounds such as percussion. The MX40 Punch Gate Frequency Conscious System ´opens´ the gate only when a signal exceeds the threshold you set within a specific and variable frequency band. This enables the gate to distinguish between a snare and a high hat, tom-toms versus bass drum etc. Drawmer´s new Peak PunchTM circuitry further improves definition by dynamically enhancing the leading edge of transient signals immediately after gate opening, so percussive sounds ´punch´ through the mix. The controls of the MX40 are designed to reduce typical lengthy and complex gate set up. Only three rotary controls are needed per channel: ´Frequency Trigger´ sets the frequency band the gate reacts to; ´Threshold´ sets the level at which the gate opens; ´Release´ determines how long before the gate closes after falling below the set Threshold level.Push button options include Peak Punch On/Off, ´Frequency Trigger´ On/Off, -20dB or -90dB Attenuation and Gate Bypass. The industry standard Drawmer red/yellow/green ´traffic light´ LED display gives the user reliable indication of gate status. Special features include ´Key Listen´ that enables the user to hear just the trigger signal for easier set-up. If Frequency Conscious operation (Frequency Trigger On) is used, depressing Key Listen will enable the user to hear only the frequency band ´tuned´ in on the Frequency Trigger rotary control. External Key allows the gate to be opened by an external signal. The MX40 can also be set so Channel One triggers all other gate channels, and ´Slave Link´ links Channel One and Two together and/or Three and Four.Controls: -> Threshold: This rotary control sets the level at which the gate opens (or closes) and may be set anywhere between -60dB to +20dB. All signals below Threshold will be reduced by -20dB or -90dB, depending on the ´Range´ control setting. All signals above threshold will pass through the gate. -> LED Display: Drawmer´s familiar traffic light LEDs display envelope status. When the gate is closed (signal below the set Threshold level) - the red LED is illuminated. When the gate is open (signal above the set Threshold level) - the green and amber LEDs illuminate and the red LED is off. As the signal falls below the set Threshold level, the green LED will extinguish and the amber LED fades over the duration of the Release time. -> Release: The Release time may be set from 10mS to 4S. This control determines how long before the gate closes. Special logic circuits within the MX40 incorporate ´envelope hold´ constants that are variable with Release time settings. This is to prevent ´chatter´ when processing signals that decay near Threshold. -> Range: This button determines how much gain reduction is applied when the gate is fully closed. A setting of -90dB effectively silences the signal completely when the gate is closed, while the -20dB setting allows the signal to pass through the gate with a 20dB decrease in gain. -> Peak Punch: Drawmer´s proprietary Peak PunchTM circuitry adds very short term dynamic expansion to the leading edge of percussive material. Peak PunchTM has a near zero Attack time and enables gated signals to ´punch´ through a mix without increasing long term signal level. The effect is one of greater signal definition of transient information. When Peak...

The ultimate ´´color box”. As a 500-series follow-up to the Portico 5042, the 542 delivers the same thick, musical simulation of tape while drastically enhancing creative control via a number of new features. In addition to the the ´´true tape” circuitry – great for bringing out 3rd-order harmonics – the 542 incorporates a soft-clip circuit that tames the harshest sources and enhances 2nd-order harmonics, a variable and versatile Silk/Texture circuit for three transformer tones in one, and a wet/dry control to blend in the perfect amount of saturation.The 542’s ´´True Tape” emulation circuit provides the nostalgic rounding and compression usually only achieved by the use of tape, and can offset the harshness often found in digital recordings. Unlike digital emulations, the ´´True Tape” drive circuit works by feeding a custom-designed transformer acting as a ´´record head”, which in turn is coupled to a correctly equalized replay amplifier. As the voltage rises on the ´´record head”, saturation increases, and a soft clip circuit engages at higher levels to round off peak transients. The sound of the tape circuit can be further modified with selectable 15 / 30 IPS modes and a pre/post-tape blend control. In addition to the tape circuit, the 542 also has the variable Silk & Texture circuitry developed for the Portico II series modules, which allows the engineer to fine-tune the harmonic ratio and tonality on the output transformer.Getting the Most Out of the 542While in the olden days, tape’s non-linearity was generally looked upon as more of a curse than a ´´feature”, the advent of digital systems that operate in a completely linear fashion has made many appreciate the quirks of non-linear audio processing. Unlike linear designs, non-linear devices require the user to actively experiment with gain staging to find the ´´sweet spot” of the circuit. Although this requires a small amount of effort on part of the engineer, if used properly, the effect can add a dynamic aspect to performances that can enhance the impact of a song.The non-linearity in the 542’s ´´True Tape” circuitry and Saturation control necessitate taking note of both drive and input levels. How levels are staged into the 542’s tape circuit can significantly impact tone, depending on the position of the saturation control and the drive level on the tape circuit. As saturation is increased, low frequency compensation is decreased, and at a drive level of 5 the soft clipper enters the circuit. Finding the best balance point between low frequency response, total harmonic distortion, and desired soft clipping require playing with a combination of the saturation, trim and blend controls, and may also include using dynamics processing and proper gain staging before the 542.As a rough guide, we recommend starting with an input signal from around 2-10dBu and applying saturation, 15 / 30 IPS, Silk, and blend to taste. However, it always behooves the engineer to experiment with the balance between the pre-tape signal level and the level of the saturation control to find the best results for each source.To get a better idea of what is happening at different saturation and ´´Tape Head” levels, look through the frequency response and THD by frequency response graphs in the Technical Specifications section at the end of the manual.Also, like a real tape machine, the flux loops in the ´´True Tape” circuitry can pick up signals from strong nearby magnetic fields (The most likely sources are nearby power supplies, power amplifiers and computer monitors). Although we have shielded both the unit as a whole and the tape circuit to minimize stray inductance, if you have issues with hum when engaging the tape circuit, try moving the 542 to other spots away from magnetic field radiators until the hum subsides.Adding TextureBoth Silk modes are modified and fine tuned by the ´´Texture” control. By manipulating the Texture control, the amount of Silk can be changed from essentially absent, to roughly four times the amount of coloration found in Silk from the original Portico Series. With Silk / Texture engaged, the distortion characteristic and harmonic content of the unit are very reminiscent of many of Rupert’s vintage class-A designs. These controls add another realm of tonal control to the 542, and should be explored creatively in conjunction with the ´´True Tape” for best effect.Designed for 500 Series by Mr. Rupert...
