Antilock Brake System Abs Model Based Design Computer Science Essay

Antilock Brake System Abs Model Based Design Computer Science Essay An Antilock Brake System (ABS) is a closed loop control system that modulates the brake torque that is applied to the wheel in order to prevent the controlled wheel from becoming fully locked. ABS is among the most important safety systems in a vehicle. In automatic highway system, automatic brake actuation is a very important part of the overall vehicle control system. It prevents the wheel lock-up under critical braking conditions, such as those encountered with wet or slippery road surfaces and driver panic reaction (Bosch, 1995). By preventing the wheel lock-up, ABS ensures that the vehicle remains responsive to steering wheel inputs. Reduced stopping distance on account of ABS is more evident on wet or slippery road surfaces (Garrick et al., 1998). 1.2 MODEL BASED DESIGN Designers of embedded control system software face difficult challenges. In addition to the need to complete projects at low cost and within tight schedules, embedded control system software designers must prov ide predictable performance and competitive features for the products they deliver. Traditional methods of designing, testing, and implementing embedded control systems cause designers to wait until late in the design effort, when actual or prototype products and real-time embedded targets become available, to find out if software really works as it was intended to. Only then, as system integration occurs, can the designer uncover the errors that may have found their way into the product during the early design stages. Model-Based Design with MathWorks tools provides a proven technique for creating embedded control systems. It is used today for satellites, aircraft, and many other aerospace applications, in the automotive industry, and for process control, computer peripherals and industrial machinery. Through Model-Based Design, embedded control system design teams can begin evaluating software designs without using prototype products and real-time targets. The MathWorks environmen t for Model-Based Design allows engineers to mathematically model the behavior of the physical system, design the software and model its behavior, and then simulate the entire system model to accurately predict and optimize performance. The system model becomes a specification from which you can automatically generate real-time software for testing, prototyping, and embedded implementation, thus avoiding manual effort and reducing the potential for errors. Fig 1.1. Model-Based Design for embedded control system software Changes or corrections to the system requirements and specifications are easily incorporated into the model, fully evaluated by simulation, and automatically reflected in the final real-time embedded software. 1.3. MODELING AND SIMULATION To effectively design an embedded control system and accurately predict its performance, designers must understand the behavior of the entire system in which the control system will reside. MATLAB and Simulink form the core environm ent for Model-Based Design for creating accurate, mathematical models of physical system behavior. The graphical, block-diagram paradigm of the MathWorks environment lets you drag-and-drop predefined modeling elements, connect them together, and create models of dynamic systems. These dynamic systems can be continuous-time, multi-rate discrete-time, or virtually any combination of the three. You can create custom model elements or reuse legacy code-based models by incorporating C, Fortran, or Ada code directly into the modeling environment.

Leadership Analysis - Essay Example Leadership qualities in the roles of such characters as Brian Cassidy, Elliot Stabler, Amanda Rollins, Nick Amaro, Fin Tutuola, John Munch, and Olivia Benson come into sharp focus as cases of sexual assault characterize their daily duties (Green, Dawn & Wolf, 2009). Viewers have a chance to witness the backdrop of the most thrilling and bizarre occurrences of the conditions facing their victims and the overwhelming interrogations the detectives involve the suspects. Personal skills, character traits remain as the most overt leadership qualities in the twelve series show. This research paper examines the extent to which human involvement employ the leadership theories as seen in the T.V series, Law & Order: Special Victim Unit. Law & Order: Special Victims Unit is a fascinating T.V series, a crime drama of the Law $ Order (Green, Dawn & Wolf, 2009). It is a daily activity of detectives, who work in the Special Victim Unit of the 16th Precinct. This unit, set from the New York City Pol ice Department, centers on crimes related to rape, sexual attack, and child molestation. All these are inhumane acts and subject to the Holy book are punishable. The unit captures all other closely related to domestic mistreatment such as household cruelty, kidnapping, and child desertion. Since its premiere in 1999, the series has largely featured four detectives, who tirelessly work for the unit (Green, Dawn & Wolf, 2009). As the program is in a season series format many seasons, in most of them, five detectives seem to run the show under the leadership of Donald Cragen. For the detectives work to be complete and decisive, the unit has a prosecutor assigned form the DA’s office. The main role of the prosecutor is to interact with the assigned examiners and the unit’s psychiatrist George Huang (Green, Dawn & Wolf, 2009). As the series unfolds into the different seasons, related characters come in full view. Series is largely about things, which need continual talking throughout our daily lives. The detective’s moves and involvements focus on things that everyone sees only in cable news, and this makes domestic crime revelation that it is a serious act of violation. The series creates awareness to its viewers. This makes the cases and the characters a big part of why the series has had a long and a successful run. As viewers watch the detectives run through daily operations, one gets a mixer of different people operating on a different level of thinking, and operations. Even though the show is enjoyable, and its content interesting, some of the scenes are downright offensive. Viewers can see the leadership rationale employed by the protagonist of the show in making some decision sometimes going beyond human ethics. For example, the detectives make entries into people’s lives and homes without consideration of their cultural, religious, or lifestyle practices. This goes beyond the Biblical principle of extending honor unto others. As much the operations of any police department deserve no boundaries in pursuit of justice towards their clients, the unit leadership ethics should have embraced some decency. As a viewer, sometimes you would wonder why this policing system in the unit beat up suspects, sometimes with no consequences. Does it mean that the legal system they use is purely for their own gain? According to the Holy Law, any interrogation should be subjective and none-coaxing. For example, in some scenes

On what grounds has the Washington Consensus been criticized Is the Post Washington Consensus a viable alternative Critically discuss - Essay Example licy of the developing nations only that includes reduction of government deficits, liberalization and deregulation of international trade as well as cross border investment. This term was first used by John Williamson in 1989. It was used to describe a set of ten specific economic policy prescriptions that was considered by his as the standard reform package promoted for the crisis wracked developing countries. This consensus was influential during the 1990’s. During the first decade of the 21st century, this concept became increasingly controversial. After the outbreak of the economic chaos during 2008 and 2009, it was thought that Washington consensus has found its end (Poverty and development policy). John Williamson who used this term first used this to support the commonly shared themes among the policy advices by Washington based financial institutions. These institutions were the IMF, World Bank and the US treasury department. These policies were believed to be used for the recovery of Latin America from the financial crisis of the 1980’s. But Williamson’s concept of the theme was neoliberal in its approach. Even though the policy was put forward by Americans, the policy makers in Latin America used their own perspectives to develop these and introduce them in their own countries. These were developed keeping in mind what happened inside and outside the country. It was also said that these policies were largely a creation of Latin American politicians and technocrats and Williamson being a person to gather these policies first at one place. Neo liberalists argue that Washington consensus is a set of policies that are imposed on hapless countries by the Washington based international financial establishments. They also argue that these policies have increased the misery of such countries than before. This concept that was initiated by John Williamson inspired a wave of reforms in Latin America and sub Saharan Africa. This policy fundamentally
