Takeoff Angle

There Have Been Many Papers Written And Published On The Subject Of Pedestrian Throw Distance With Automobiles. Many Of These Papers Can Be Obtained From The Society Of Automotive Engineers (Sae). Many Of The Papers Make Assumptions For The Takeoff Angle Of The Pedestrian. Some Of Those Authors Have Performed Tests Using Dummies Or Objects Dropped From Moving Vehicles In Order To Draw Correlations Between Their Formulae Or Equations And Real Life. Generally, Those Authors State How The Formulae Should Be Used, And Specify That If The Pedestrian Mounts The Vehicle, The Formula Is Not Valid. Despite The Disclaimers Of How And When To Use The Published Formulae, The Writer Has Noticed That Accident Reconstructionists Tend To Misuse The Formulae And Often Arrive At Speeds For An Impacting Vehicle Higher Than Can Be Justified By More Rigorous Analysis. This Occurs Because The Theories Behind The Formulae, Its Assumptions, And Its Application Are Not Known Or Are Not Understood Well. The Writer Has Found, In His Experience, That The Reconstruction Practioners Often Use The Distance From The First Impact With The Pedestrian To The Rest Position Of The Pedestrian As The Distance Factor In The Formulae Without Giving Thought As To Whether The Pedestrian Mounted The Vehicle Or Not.

The Investigation Of Recreational Accidents Often Involves An Analysis Of Unique Circumstances And Unique Equipment Not Commonly Found In More Traditional Forensic Engineering Investigations. In The Case Of The Kite Surfing Accident Which Is The Subject Of This Paper, It Was Alleged That The Quick-Release Mechanism Failed To Function Properly, Which Caused The User To Be Dragged To A Rocky Shore Causing Injuries. The Engineer Had To Familiarize Himself With The Various Components Of The Kite And Harness System, How The Interaction Of Those Components Under The Control Of The User Led To The Accident, And How The Accident Could Have And Should Have Been Avoided. Conditions Specific To The Subject Accident Were Investigated, Including The User Familiarity With Equipment And Emergency Protocols, Wind Patterns Present At The Time Of The Accident, And Geography Of The Accident Location. Finally, Research Revealed That There Were No Standards Or Regulation Of The Kite Surfing Industry In The United States, But That The Manufacturers Of The Equipment Claimed Compliance With A Foreign Standard. The Equipment Was Then Tested To Determine Whether It Was In Compliance With That Foreign Standard. This Paper Will Address The Proper Operation Of The Kite Surfing Equipment, And Will Describe The Testing That Was Performed By The Engineer To Determine The Effectiveness Of The Quick-Release Component Of The System. It Also Addresses Actions That Were Taken By The User To Attempt Avoidance Of The Accident.

Main Components

The article provides a comparative analysis of the influence of L.N. Tolstoy and I.I. Sergiev (John of Kronstadt) on the formation of personal worldview in Russian society. The analysis is based on the testimonies of the contemporaries and the previously not reissued publication of “Novy Put” (“New Way”) journal on the subject. In the context of the declared problematics, special attention is paid to the question of transformation of religious consciousness in the course of the personality formation in relation to the period under consideration (the beginning of the 20th century). The author reveals and analyzes the main components of the life stand of Tolstoy and Father John of Kronstadt in the context of their influence on contemporaries. The results of the study allow to reveal the following antitheses that characterize Tolstoy and John of Kronstadt, respectively: doubt - faith, search for oneself – following the once chosen path, preaching of non-resistance as part of the philosophy of not-doing (not doing evil) – preaching of active upholding of faith (doing good), “simple living” – real life with and for common people.

Over Time

Storytelling consists of an interaction between a narrator and a listener, both of whom assign meaning to the story as a whole and its component parts. The meaning assigned to the narrative changes over time under the influence of the recipient‟s changing precepts and perceptions which seem to be simplistic in infancy and more nuanced with age. It becomes more philosophical in that themes touching on the more profound questions of human existence tend to become more prominently discernible as the subject moves into the more reflective or summative phases of his or her existence. The aim of this article is to demonstrate the metaphorical character of a story, as reflected in changing patterns of meaning assigned to the narrative in the course of the subjective receiver‟s passage through the various stages of life. This was done by analysing meaning, from a particular storytelling session, at different stages of a listener‟s personal development. Meaning starts as literal and evolves through re-interpretation to abstract and deeper levels towards application in real life.

The Relationship

AbstractLearning is a complex phenomenon. Contemporary theories of education underline active participation of learners in their learning processes. One of the key arguments supporting this approach is the learner’s simultaneous and unconscious development of their ability of “learning to learn”. This ability belongs to the soft skills highly valued by employers today.For Mathematics Education, it means that teachers have to go beyond making calculations and memorizing formulas. We have to teach the subject in its social context. When the students start understanding the relationship between real-life problems and the role of numbers and formulas for their solutions, their learning becomes a part of their tacit knowledge. Below we explain the theoretical background of our approach and provide examples of such activities.

<p>Professional engineers in the US may be found negligent and therefore liable for damages arising from failure to exercise a level of care, diligence, and skill exercised by other reputable practitioners in similar circumstances in an effort to accomplish the purpose for which the professional engineer was hired. If the professional engineer has accepted the obligation to design for sustainability or durability, or where materials, elements, or assemblies are intended by design to be “pushed to their limits” in normal service, the professional engineer may be accepting an extreme or uninsurable risk.</p><p>The subject of this paper is the standard of care and the relationship between the standard of care and design for sustainability or durability, or design where the engineered features are expected to be “pushed to their limits” in normal service. The paper’s contents include 1) an explanation of the concept of the standard of care, and 2) the professional liability pitfalls inherent in a design effort intended to result in sustainability or durability, or intended to achieve limit-state behavior in normal service. The subject is relevant for practitioners wishing to understand professional responsibilities for such designs.</p>

The Subject

It has been determined that the drawings, photographs and pictures related to the subject of the continuity of the tangent function on page 68 of the Ministry of National Education’s twelfth-grade mathematics textbook contradict principles 1, 7 and 10 of Yanpar’s (2007) teaching material development principles. According to these principles, teaching materials should: i) be simple, plain, and understandable, ii) reflect real life as much as possible, and iii) be easy to develop or revise, if necessary. This study aims to develop a portable tangent bridge model to meet the needs of the subject of the continuity of the tangent function. With this aim: i) teaching with the analogies model in the design of the teaching material, ii) “this is my project” format in the development and iii) Yanpar’s (2007) principles were considered. The design of the model lasted 14 weeks. At the end of the study, a portable tangent bridge model from waste products was designed and developed. This model is thought to contribute to the teaching effectiveness of teachers (Shulman, 1987) with content knowledge alongside with pedagogical knowledge (Shulman, 1986). With this contribution, the needs of the subject as described by Taba (1962) and Tyler (1949) will be met. This model will also serve as an example of meeting the needs of the subjects of knowledge and its product, technology, as highlighted by Cahit Arf (Terzioglu &amp;Yilmaz, 2006).

The Influence Of Construction And Pile Driving Vibrations On Surrounding Buildings, Including Hospitals And Eye Examination Facilities, Sensitive Devices Such As Computers And Surgical Microscopes Or Electronic Machines, And People In The Urban Environment Is A Significant Consideration In Obtaining Project Approvals From Appropriate Agencies And Authorities. Implementation Of Construction Projects In Areas Adjacent To Existing Buildings (Aged, Historical, Residential, Commercial, Industrial, Medical Services, Or Electronic Services) Creates Additional Difficulties. Specialized Case History Is Presented Where Damage To Sensitive Structures From A Variety Of Vibratory Construction Methods Ranging From Pile Driving, Highway Construction, Rock Excavation And/Or Blasting, Was Considered. Twenty Homeowners From A Residential Subdivision In The Florida Panhandle, Claimed Damage Including Cracking To Their Properties During Construction Of Various Portions Of City Storm Water Treatment/Enhancement Project. It Was Also Alleged That During Excavation And Construction Of Drainage Structures, Especially Four Subsurface Treatment Vaults That Required Installation And Extraction Of Sheet Piles Using Vibratory Hammer, Stability Of The Nearby Residential Structures Was Endangered And Resulted In Movement/Cracking. Forensic Engineering Analysis Was Effectively Utilized To Identify, Investigate, And Remediate The Concerns As Well As Assist In Litigation And In Some Cases Avoidance. This Technical Paper Presents Some Legal Issues Related To Litigation, Mediation, And Resolution Involving Jurisprudence System And Introduces A Case History That Includes All Elements Of Forensic Engineering.
