Download PDF Leadership in Chaordic Organizations by Beverly G. McCarter

Sinopsis

We use the term complex to describe people, their perceptions, motivations, mindsets, personalities, and so forth, but primarily their behaviors. People’s actions, as expressed by verbal, written, and body language and physical activities, are what impact others directly. Organizations include people and thus are also complex. However, as Covey states, “In a very real sense there is no such thing as organizational behavior. There is only individual behavior collectivized in organizations” (Covey, 2004, p. 102). Typical organizations try to utilize people, processes, and technologies to accomplish specific goals. Often there are “systems” involved. A system can be thought of as a collection of elements (e.g., people, processes, and technologies) that is intended to achieve a purpose that is greater than any subset of the elements. When systems include people, they are also complex.

Download PDF Programming for the Series 60 Platform and Symbian OS by DIGIA Inc.

Sinopsis

The market drive towards advanced mobile services such as multimedia messaging and wireless access to the Internet sets high requirements for the terminals and networks. New devices (and networks) must be able to handle still and moving images, music, allow access to the Internet for messaging and browsing, and provide a diverse set of applications in addition to operating as a mobile phone.
 

As 2.5G and 3G networks emerge, the focus is turned to the terminal – what kind of capabilities are required by these new services and how can they be fulfilled? This book presents one significant platform for smartphones – devices that are designed to meet the increasing requirements of the new services – Series 60. It is a platform made by Nokia on Symbian OS (Operating System), which in turn is an operating system designed for mobile devices.
 

Owing to these requirements of the new services, the task of making the software for wireless devices is becoming increasingly complex. As new protocols, communication interfaces, services, and applications are integrated, the required R&D effort grows rapidly. This increases the development cost significantly and sets high demands on interoperability testing. Symbian was formed in 1998 by Ericsson, Motorola, Nokia, and Psion to provide a common standard and to enable the mass marketing of a new era of wireless devices. Matsushita (better known by its brand name, Panasonic) joined Symbian in 1999, in January 2002 the Sony Ericsson joint venture took a share of Symbian, and, in April 2002, Siemens also joined Symbian as a shareholder (www.symbian.com).
 

The cost of the hardware components (i.e. bill of materials) used for making a mobile phone is one of the most important factors in making competitive devices, but the cost of developing and maintaining the increasing number of features of the software also becomes more significant as the world evolves towards wireless multimedia. When the mobile phone shipping volumes are low, the price of the hardware components, especially the most expensive ones, such as the color display, is high.When components are made in high volumes, the price of a single component is reduced. New requirements are set for the operating system by the need to open the devices for developing thirdparty applications in order to have a more diverse set of applications to attract more users and to increase volumes.
 

A typical smartphone is attractive for users looking for more features compared with the basic mobile phone. Also, for those seeking better personalization, a smartphone is likely to be a natural choice. A smartphone is, as its name states, a phone, but with capabilities such as color screen, advanced messaging, calendar, browser, e-mail, synchronization with other devices, and, installation of applications.
 

From the device manufacturer perspective, it is vital that the software is stable and reliable – especially if it is possible for the user to install new applications. A serious software or hardware defect may force a manufacturer to call back all the mobile devices. The costs of such an operation are very significant even when compared with development costs. From the software point of view, the right selection of software platform will reduce the risk of failure.
 

Series 60 Platform is particularly appealing for the terminal manufacturers, as it allows Symbian OS with multimedia capabilities to be used in devices that are only slightly more expensive than the devices equipped with a proprietary operating system. Series 60 Platform provides the benefit of open interfaces, efficient power management, and advanced multimedia capabilities. From the application developer perspective, Series 60 is also very interesting, as the compact size and reasonable price of the devices leads to large market penetration, thus making the application development worthwhile as well.
 

This book is written by the software professionals of Digia – a company that has been heavily involved with Symbian OS and Series 60 Platform and application development since early 1999. During that time, knowledge of the platform has been accumulated in demanding, time-critical projects and in developing products for Symbian OS. 

This book is a handbook of software development for the Series 60 Platform, written by software professionals for software professionals – and for individuals who want to become experts on Series 60
software development. The approach of this book is to build on top of the previous publications on Symbian OS and to provide a guide for the art of developing software for the Series 60 Platform. The intended audience is anyone interested in learning more about Symbian OS and the Series 60 Platform. It is specially beneficial for software developers who can use the code examples for illustrating the key aspects of Series 60 software development.

Hacking Video Game Consoles Turn your old video game systems into awesome new portables by Ben Heckendorn

Sinopsis

On New Year’s Eve 1999, some friends and I were wandering around downtown Madison, Wisconsin, waiting to start celebrating (typically around 3–4 p.m. in our state). During our travels, we came across a used-game store and inside, they had a glass case containing Atari 2600 cartridges. Much to my surprise, some of them were quite expensive!
 

“Do people actually pay money for Atari games?” I asked the friendly shop manager. “Oh yeah...” he replied, kindly pausing from his hamburger consumption to set my feet upon the path of knowledge. “People buy that stuff all the time.”
 

This amazed me. You see, I’ve been an Atari fan as far back as I can remember, which translates to approximately 1980. Because my parents had bought into that “it will ruin your TV!” myth, I was pretty much the only person I knew who didn’t have one, but I still managed to play a lot, thanks to my friends and relatives. A few years later, I managed to get an Atari 800 computer, which held me over pretty well until, one glorious day in 1994, I plunked down $20 for my first, very own Atari 2600 game system (complete with dust, grime, and flaky joysticks). Sure, I played SNES and Playstation during the 90’s like everyone else, but I still kept the Atari hooked up so I could squeeze off a round of Space Invaders or Asteroids if I felt like it.
 

Seeing those Atari games in that store got me thinking... maybe I wasn’t the last fan out there... maybe I wasn’t alone. Luckily, the Internet (and the world) didn’t end at the stroke of midnight as some had predicted, so I was able to do a search the next day. Sure enough, a huge fan base for Atari existed, with people even programming new games for the 2600, as well as other old systems! I felt vindicated!

Download PDF Population Systems A General Introduction by Alan A. Berryman And Pavel Kindlmann

Sinopsis

Populations are made up of individual organisms, which interact and communicate with each other as they pursue their normal lives. For example, individuals mate, compete for scarce resources, and cooperate to capture prey or escape being eaten. As a result of these interactions individuals reproduce, move and die and these processes cause the population as a whole to behave in certain ways - populations grow, decline, or remain steady.

Any system you wish to consider, a television set or an automobile, is basically composed of a set of interacting parts that together produce patterns of behavior, which are characteristic of the system. This behavior is determined by the rules of interaction, and the overall structure of the interaction network. Populations, therefore, can be thought of as particular kinds of systems with their own rules and structure, which – nevertheless - obey certain general system laws. In the first chapter of this book we will take a brief excursion into the theory of dynamic systems in order to understand the properties and behavior of systems in general. Then these concepts will be applied to the analysis of single-species populations. In Chapter 2 a very simple model is developed from observations of the behavior of natural populations, which will help us to understand the fundamental rules of population growth. Then in Chapter 3 a more detailed model of the population system is created, along with a methodology for analyzing the behavior of dynamic population systems inhabiting variable environments.

Sinopsis

Systems biology aims at a system-level understanding of biological systems (1,2). The investigation of biological systems at the system level is not a new concept. It can be traced back to homeostasis by Canon (3), cybernetics by Norbert Weiner (4), and general systems theory by von Bertalanffy (5). Also, several approaches in physiology have taken a systemic view of the biological subjects. The reason why “systems biology” is gaining renewed interest today is, in my view, due to emerging opportunities to solidly connect system-level understanding to molecular-level understanding, as well as the possibility of establishing well-founded theory at the system level. This is only possible today because of the progress of molecular biology, genomics, computer science, modern control theory, nonlinear dynamics theory, and other relevant fields, which had not sufficiently matured at the time of early attempts.

However, “system-level understanding” is a rather vague notion and is often hard to define. This is because a system is not a tangible object. Genes and proteins are more tangible because they are identifiable matter. Although systems are composed of this matter, the system itself cannot be made tangible. Often, a diagram of the gene regulatory networks and protein interaction networks are shown as a representation of systems. It is certainly true that such diagrams capture one aspect of the structure of the system, but they are still only a static slice of the system. The heart of the system lies in the dynamics it creates and the logic behind it. It is science on the dynamic state of affairs.

There are four distinct phases that lead us to system-level understanding at various levels. First, system structure identification enables us to understand the structure of the systems. Although this may be a static view of the system, it is an essential first step. Structure is ultimately identified in both physical and interaction structures. Interaction structures are represented as gene regulatory networks and biochemical networks that identify how components interact within and between cells.

Physical details of a specific region of the cell, overall structure of cells, and organisms are also important because such physical structures impose constraints on possible interactions, and the outcome of interactions impacts the formation of physical structures. The nature of an interaction could be different if the proteins involved move by simple diffusion or under specific guidance from the cytoskeleton.

Second, system dynamics need to be understood. Understanding the dynamics of the system is an essential aspect of study in systems biology. This requires integrative efforts of experiments, measurement of technology development, computational model development, and theoretical analysis. Several methods, such as bifurcation analysis, have been used, but further investigations are necessary to handle the dynamics of systems with very high dimensional space.

Third, methods to control the system have to be investigated. One of the implications is to find a therapeutic approach based on system-level understanding. Many drugs have been developed through extensive effect-oriented screening. It is only recently that a specific molecular target has been identified, and leading compounds are designed accordingly. Success in control methods of cellular dynamics may enable us to exploit intrinsic dynamics of the cell, so that its effects can be precisely predicted and controlled.

Finally, designing the system—i.e., modifying and constructing biological systems with designed features. Bacteria and yeast may be redesigned to yield the desired properties for drug production and alcohol production. Artificially created gene regulatory logic could be introduced and linked to innate genetic circuits to attain the desired functions (6).

Sinopsis

What is systems biology? Over the past 40 years, practicing systems biologists delimited their field in a great number of ways. At times the definition was restricted to applications of the formal systems theory in biology; more recently, the tendency has been to focus on biomolecular interactions or on multivariate analysis as systems biology’s proper subject and method (1– 5) . This essay is written from a conservative biologist’s perspective and takes a less specific view of the topic. First, what should we call a system, in the context of the scientific way to parse the world into concepts? We recognize a system in a certain number of different and interacting objects. Noninteracting objects do not form a system. Also, it is hardly useful to see any substantial number of interacting, but identical objects as a system. Science has powerful methods to study aggregate behavior of identical objects. Notably, such methods tend to disregard the corpuscular nature of the individual objects and take a view of their collections as continua. In this case, biology can freely borrow methodologically from established areas of physics. In contrast, studying behavior of collections of interacting nonidentical objects remains a methodological challenge. We will, therefore, restrict the meaning of “system” to a system of interacting nonidentical parts. Study of a living object by discerning so-defined systems in it will then be called systems biology. Its status as a distinct discipline should engender no jealousy: The definition limits the subject of systems biology to what the scientific method is currently handling perhaps least confidently.

The difficulty appears to stem from the limitation of the human mind itself (6, 7) : we are nearly incapable of considering more than a few things at a time. Psychophysical experiments suggest the limit of about seven, which corresponds well to the number of the nonidentical, interacting elements that deserve to be called a system, as commonly perceived in the systems biology practice. It is important to observe that the limitation is not just to our intuition, but to rational reasoning as well. We can consider larger systems of course, but the effects resulting from interactions of more than a few elements at a time will likely be missed. To reason about systems whose complexity is beyond our immediate grasp, we must extend our mind with formal deduction, under the general rubric or mathematics. As applied to the natural world, it is termed mathematical modeling. Involving mathematics in nonsystems biological research can be necessitated by a desire of quantitative precision in understanding; in systems biology, it is indispensable for any progress whatsoever, because even the crudest qualitative effects are liable to be overlooked by the unaided mind that has evolved for rather different purposes.

That quantitative precision is rarely sought in modern systems biology is important to recognize, so as not to confuse the nature of the mathematics employed with the goals of the investigation. And certainly, those who are just considering employing systems analysis especially should not decide against it, if it is qualitative inference about their subject that they are after. We owe the quantitative, continuous-variable flavor of our most widely applied mathematics to its original development for the purposes of celestial mechanics and similarly particular problems of quantitative precision. As a consequence, the modern systemsbiological modeling has to be done most commonly in terms of dynamics of continuous quantities first, to an exceeding precision (“phosphorylation goes up by 73%”), and then the results are reinterpreted in terms of qualitative statements about discrete events (“this genotype permits cell division”), to arrive at the kind of knowledge that is actually being sought. This is no different from how experimental measurements are most commonly employed.

Download PDF Automobile Mechanical and Electrical Systems Automotive Technology: Vehicle Maintenance and Repair by Tom Denton

Sinopsis

The rear engine design has not been very popular but it was used for the best selling car of all time: the VW Beetle. The advantages are that weight is placed on the rear wheels, giving good grip, and the power unit and drive can be all one assembly. One downside is that less room is available for luggage in the front. The biggest problem is that handling is affected because of less weight on the steered wheels. Flat-type engines are the most common choice for this type of vehicle.

Fitting the engine in the mid-position of a car has one major disadvantage: it takes up space inside the vehicle. This makes it impractical for most ‘normal’ vehicles. However, the distribution of weight is very good, which makes it the choice of high-performance vehicle designers. A good example is the Ferrari Testarossa. Mid-engine is the term used to describe any vehicle where the engine is between the axles, even if it is not in the middle.

Download PDF Programming Embedded Systems in C and C++ 1999 by Michael Barr

Sinopsis

An embedded system is a combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a specific function. A good example is the microwave oven. Almost every household has one, and tens of millions of them are used every day, but very few people realize that a processor and software are involved in the preparation of their lunch or dinner.
 

This is in direct contrast to the personal computer in the family room. It too is comprised of computer hardware and software and mechanical components (disk drives, for example). However, a personal computer is not designed to perform a specific function. Rather, it is able to do many different things. Many people use the term general-purpose computer to make this distinction clear. As shipped, a general-purpose computer is a blank slate; the manufacturer does not know what the customer will do with it. One customer may use it for a network file server, another may use it exclusively for playing games, and a third may use it to write the next great American novel.
 

Frequently, an embedded system is a component within some larger system. For example, modern cars and trucks contain many embedded systems. One embedded system controls the anti-lock brakes, another monitors and controls the vehicle's emissions, and a third displays information on the dashboard. In some cases, these embedded systems are connected by some sort of a communications network, but that is certainly not a requirement.

Download PDF Debian 7: System Administration Best Practices Learn the best ways to install and administer a Debian Linux distribution by Rich Pinkall Pollei

Sinopsis

"What is the best distribution for my needs? What do I need to know to administer a Debian system? What's different about Debian? What is the best way to handle something specific in Debian? I ran an Internet search on these questions and got millions of results. Now what do I do? Can someone help me?" The answer to the last question is yes. Answering the others requires a bit of background. This discussion is oriented towards those who are new to Debian. In it, we'll cover Debian's place among the various Linux distributions, project organization (and how that impacts administration), and licensing issues. Those who are already familiar with Debian may wish to skip ahead to the next chapter.

Debian is just one of many Linux distributions. Selecting which distribution is best for your deployment can be a rather daunting task. The reason for so many distributions is that the developers or sponsors of each have a different vision of which software should be installed by default, which software is appropriate for particular tasks, and how the system is best administered. This means that selecting a distribution that matches your purpose and preferences will make installation and administration easier.

Linux distributions can be broken down into three branches, named from their original distribution or their package managers: SLS, RPM, and DPKG.

The Softlanding Linux System (SLS) distribution, which evolved into the Slackware distribution, is one of the oldest. Distributions in this branch generally made minimal or no changes to the original software packages before including them. Distributions using this format generally provided no native software management and depended on third-party utilities for package management and administration. These utilities were readily available and often included, so this was not necessarily a disadvantage.

The Debian Packaging System (DPKG/DEB) was developed about the same time as the RPM, and has the same features, although they are implemented differently. DPKG refers to the original software packaging utility. This has been superseded by more flexible and user-friendly utilities, so this branch is often referred to by the extension used by the package files: DEB (.deb). Some distributions in this branch have corporate sponsorship (Ubuntu is the most notable) and thus, have a unified administrative utility, similar to SuSE's YaST for example. Others, such as Debian, depend upon third-party software to fulfill this function. The most common distributions in this branch are Debian and Ubuntu. Most of the others in the branch, such as Mint and BackTrack, are derived from one of these.

Download PDF Matlab Simulation For Radar Systems Design by Bassen R. Mahafza

Sinopsis

The word radar is an abbreviation for RAdio Detection And Ranging. In general, radar systems use modulated waveforms and directive antennas to transmit electromagnetic energy into a specific volume in space to search for targets. Objects (targets) within a search volume will reflect portions of this energy (radar returns or echoes) back to the radar. These echoes are then processed by the radar receiver to extract target information such as range, velocity, angular position, and other target identifying characteristics.
 

Radars can be classified as ground based, airborne, spaceborne, or ship based radar systems. They can also be classified into numerous categories based on the specific radar characteristics, such as the frequency band, antenna type, and waveforms utilized. Another classification is concerned with the mission and/or the functionality of the radar. This includes: weather, acquisition and search, tracking, track-while-scan, fire control, early warning, over the horizon, terrain following, and terrain avoidance radars. Phased array radars utilize phased array antennas, and are often called multifunction (multimode) radars. A phased array is a composite antenna formed from two or more basic radiators. Array antennas synthesize narrow directive beams that may be steered mechanically or electronically. Electronic steering is achieved by controlling the phase of the electric current feeding the array elements, and thus the name phased array is adopted.

This includes: weather, acquisition and search, tracking, track-while-scan, fire control, early warning, over the horizon, terrain following, and terrain avoidance radars. Phased array radars utilize phased array antennas, and are often called multifunction (multimode) radars. A phased array is a composite antenna formed from two or more basic radiators. Array antennas synthesize narrow directive beams that may be steered, mechanically or electronically. Electronic steering is achieved by controlling the phase of the electric current feeding the array elements, and thus the name phased arrays is adopted.

Radars are most often classified by the types of waveforms they use, or by their operating frequency. Considering the waveforms first, radars can be Continuous Wave (CW) or Pulsed Radars (PR). CW radars are those that continuously emit electromagnetic energy, and use separate transmit and receive antennas. Unmodulated CW radars can accurately measure target radial velocity (Doppler shift) and angular position. Target range information cannot be extracted without utilizing some form of modulation. The primary use of unmodulated CW radars is in target velocity search and track, and in missile guidance. Pulsed radars use a train of pulsed waveforms (mainly with modulation). In this category, radar systems can be classified on the basis of the Pulse Repetition Frequency (PRF), as low PRF, medium PRF, and high PRF radars. Low PRF radars are primarily used for ranging where target velocity (Doppler shift) is not of interest. High PRF radars are mainly used to measure target velocity. Continuous wave as well as pulsed radars can measure both target range and radial velocity by utilizing different modulation schemes.

High Frequency (HF) radars utilize the electromagnetic waves’ reflection off the ionosphere to detect targets beyond the horizon. Some examples include the United States Over The Horizon Backscatter (U.S. OTH/B) radar which operates in the frequency range of , the U.S. Navy Relocatable Over The Horizon Radar (ROTHR), see Fig. 1.1, and the Russian Woodpecker radar. Very High Frequency (VHF) and Ultra High Frequency (UHF) bands are used for very long range Early Warning Radars (EWR). Some examples include the Ballistic Missile Early Warning System (BMEWS) search and track monopulse radar which operates at (Fig. 1.2), the Perimeter and Acquisition Radar (PAR) which is a very long range multifunction phased array radar, and the early warning PAVE PAWS multifunction UHF phased array radar. Because of the very large wavelength and the sensitivity requirements for very long range measurements, large apertures are needed in such radar systems.

Radars in the L-band are primarily ground based and ship based systems that are used in long range military and air traffic control search operations. Most ground and ship based medium range radars operate in the S-band. For example, the Airport Surveillance Radar (ASR) used for air traffic control, and the ship based U.S. Navy AEGIS (Fig. 1.3) multifunction phased array are S-band radars. The Airborne Warning And Control System (AWACS) shown in Fig. 1.4 and the National Weather Service Next Generation Doppler Weather Radar (NEXRAD) are also S-band radars. However, most weather detection radar systems are C-band radars. Medium range search and fire control military radars and metric instrumentation radars are also C-band.

The X-band is used for radar systems where the size of the antenna constitutes a physical limitation; this includes most military multimode airborne radars. Radar systems that require fine target detection capabilities and yet cannot tolerate the atmospheric attenuation of higher frequency bands may also be X-band. The higher frequency bands (Ku, K, and Ka) suffer severe weather and atmospheric attenuation. Therefore, radars utilizing these frequency bands are limited to short range applications, such as the police traffic radars, short range terrain avoidance, and terrain following radars. Milli-Meter Wave (MMW) radars are mainly limited to very short range Radio Frequency (RF) seekers and experimental radar systems.

Download PDF Systems Biology PROPERTIES OF RECONSTRUCTED NETWORKS by Bernhard Ø. Palsson

Sinopsis

Suddenly, systems biology is everywhere. What is it? How did it arise? The driving force for its growth is high-throughput (HT) technologies that allow us to enumerate biological components on a large scale. The delineation of the chemical interactions of these components gives rise to reconstructed biochemical reaction networks that underlie various cellular functions. Systems biology is thus not necessarily focused on the components themselves, but on the nature of the links that connect them and the functional states of the networks that result from the assembly of all such links. The stoichiometric matrix represents such links mathematically based on the underlying chemistry, and the properties of this matrix are key to determining the functional states of the biochemical reaction networks that it represents.
