Break beat

A break beat is the sampling of breaks as drum loops (beats), originally from soul tracks, and using them as the rhythmic basis for hip-hop and rap songs. It was invented by DJ Kool Herc, the first to buy two copies of one record so as to be able to mix between the same break[citation needed] or, as Bronx DJ Afrika Bambaataa describes, "that certain part of the record that everybody waits for--they just let their inner self go and get wild," extending its length through repetition (Toop, 1991). The dance the boys and girls ended up doing to break beats was called the Break, break dancing. Breaking was abandoned in favor of doing the Freak in 1978[citation needed] until it was revived and enhanced by Crazy Legs, Frosty Freeze, and the Rock Steady Crew. More recently electronic artists have created "break beats" from other electronic music. Compare with "breakbeat" below.

Although DJ Kool Herc is usually credited with being the first to cut between two copies of a record, it is likely that there were a number of like-minded DJ's developing the technique at the same time. For example, Walter Gibbons was noted in first-hand accounts by his peers for cutting two copies of the same record in his Discoteque gigs of the mid 1970s[citation needed].

Hip hop break beat compilations include Hardcore Break Beats and Break Beats, and Drum Drops (Toop, 1991).

Safety and Security Technology Deployment

Over the past several years, FMCSA has been involved in efforts to test, evaluate, and encourage the deployment of onboard safety and security systems, such as collision warning systems with adaptive cruise control, stability control systems, lane departure warning systems, and vehicle tracking systems. Through systematic deployment planning for onboard systems, FMCSA continues to be engaged in industry-government partnerships to conduct studies and relay information to promote commercial motor vehicle (CMV) safety and security.

Through this collaboration, functional specifications were developed to relay a better understanding of the functions of onboard safety and security systems and to provide insight into the safety and efficiency benefits of using the systems. FMCSA has recently released Commercial Motor Vehicle Onboard Safety and Security Systems Technology Product Guides on its website, which provides a portfolio of existing and emerging safety and security system technologies for the motor carrier industry. The purpose of this information on this site is to assist carriers, drivers, fleet managers, and other interested individuals in learning more about available safety and security systems. Currently, FMCSA is working on completing analyses of the costs and benefits of these systems and assessing the use of the systems by the industry. In the future, FMCSA plans to perform expanded testing of onboard safety systems to identify and resolve technology adoption issues, confirm and extrapolate safety and productivity benefits to the broader industry, and develop focused deployment efforts to promote expanded adoption of the systems by industry.

Architecture Development Method

The Architecture Development Method (ADM) is applied to develop an enterprise architecture which will meet the business and information technology needs of an organization. It may be tailored to the organization's needs and is then employed to manage the execution of architecture planning activities. The process flow can be seen as an image located here: Architecture Development Cycle .The process is iterative and cyclic. Each step checks with Requirements. Phase C involves some combination of both Data Architecture and Applications Architecture.Additional clarity can be added between steps B. and C. in order to provide a complete Information Architecture.Performance Engineering working practices are applied to the Requirements phase, and to the Business Architecture, Information System Architecture, and Technology architecture phases. Within Information System Architecture, it is applied to both the Data Architecture and Application Architecture.

Trafic Nagative impacts

• Wasting time of motorists and passengers ("opportunity cost"). As a non-productive activity for most people, congestion reduces regional economic health.
• Delays, which may result in late arrival for employment, meetings, and education, resulting in lost business, disciplinary action or other personal losses.
• Inability to forecast travel time accurately, leading to drivers allocating more time to travel "just in case", and less time on productive activities.
• Wasted fuel increases air pollution and carbon dioxide emissions contributing to global warming owing to increased idling, acceleration and braking. Increased fuel use may also in theory cause a rise in fuel costs.
• and tear on vehicles as a result of idling in traffic and frequent acceleration and braking, leading to more frequent repairs and replacements.
• Stressed and frustrated motorists, encouraging road rage and reduced health of motorists.
• Emergencies: blocked traffic may interfere with the passage of emergency vehicles traveling to their destinations where they are urgently needed.
• Spillover effect from congested main arteries to secondary roads and side streets as alternative routes are attempted ('rat running'), which may affect neighborhood amenity and real estate prices.
