Frogs exhibit all characteristics of living things as they move, breathe, interact with their environment, eat other animals for nutrition, grow through different life stages, excrete waste, and reproduce. Frogs typically lay eggs in water that hatch into tadpoles with tails and gills. As the female lays eggs, the male releases sperm that fertilizes the eggs, starting their development. Tadpoles eventually grow legs and lose their tails as they transform into adult frogs, completing their life cycle.
The document discusses magnetic fields produced by electric currents. It begins by introducing the Biot-Savart law, which describes the magnetic field generated by a straight wire carrying a current. It then examines the magnetic field of a circular current loop, noting that the field depends on the current I, distance R from the loop, and radius a. At large distances R compared to the radius a, the field approximates that of a magnetic dipole with a magnetic dipole moment m proportional to the current I and area A of the loop.

This document provides information about jet airliners, specifically comparing the older Boeing 747-100 model to the newer 747-8I model. It details the differences between the two models in cockpit crew size, maximum seating capacity, width, wingspan, tail height, operating empty weight, maximum takeoff weight, maximum speed, maximum range, and maximum fuel capacity. It also briefly mentions the structure of aircrafts and components like spoilers, flaps, and ailerons. Risks associated with air travel and air crashes are also referenced.
Drag is the force acting opposite to the direction of motion of an aircraft as it moves through the air. There are several types of drag which include parasite drag from parts not contributing to lift, profile drag which is the sum of skin friction and form drag, interference drag caused by interacting airflows, and induced drag which is a byproduct of lift and increases with higher angles of attack. Reducing drag can be accomplished through techniques such as aerodynamic shaping of surfaces, reducing surface roughness, and optimizing wing design elements.
This presentation discusses swept wing configurations and their applications for supersonic flight. Swept wings reduce wave drag at transonic speeds by angling shock waves away from the aircraft. Swept wings were first developed in Germany in the 1930s and became prominent with aircraft like the MiG-15 and F-86. Variations include forward swept wings, which provide maneuverability but are expensive, and variable sweep wings which can change sweep angle during flight. Swept wings provide benefits like lateral stability and delaying compressibility effects at transonic speeds.
This document provides an overview of aircraft wings, including their:
- Historical development from ancient kites to the Wright brothers' fixed-wing aircraft.
- Construction, with internal structures like ribs, spars, stringers, and skin covering the framework. Wings also contain fuel tanks, flaps, and other devices.
- Functions, as wings generate lift through Bernoulli's principle and critical angle of attack. Wing design factors like aspect ratio and camber also affect lift.
- Types based on position (fixed or movable) and structure (cantilever or strut-braced). Stability devices like ailerons and flaps are also described.
- Unconventional designs that
This document summarizes different types of airplane wings. It describes straight wings, swept-back wings, delta wings, forward-swept wings, variable-sweep wings, flying wings, dihedral wings, tapered wings, and variable geometry wings. For each type, it provides a brief definition and example shape. The document aims to provide an overview of the various wing designs used in aircraft.

A summary of theories about work motivation as they relate to behaviour in meetings. Part of a module on Workshop Facilitation on MSc Agile Software Projects
If you are to help other people to be useful in meetings, first you have to be sorted in yourself, Part of a Workshop Facilitation module on MSc Agile Software Development
Tuckman's model outlines 5 stages of group development: forming, storming, norming, performing, and adjourning. Forming involves orientation, storming involves conflict as roles and processes are established, norming involves resolution and agreement on processes, performing involves high productivity, and adjourning involves closing the group. Hargrove outlines 5 stages for reaching dialogue - polite discussion, rational debate, chaotic discussion, community dialogue, and generative dialogue. He also outlines 5 stages for collaboration - clarifying purpose, gathering views, building understanding, creating new options, and making commitments.
This document discusses theories of motivation and their application to improving motivation in workplace settings. It summarizes several prominent motivation theories, including Maslow's hierarchy of needs, equity theory, expectancy theory, and Herzberg's two-factor theory. It then describes Hackman and Oldham's job characteristics model and job diagnostic survey, which drew from prior theories and was used to empirically measure motivational factors in jobs. The document advocates using the job diagnostic survey to diagnose motivation issues, implementing changes, and periodically re-measuring to verify improvements and sustain motivation over time.
This document discusses the lack of empirical evidence around what should be taught for facilitating software projects and working with stakeholders. It notes that most of the existing approaches come from practitioner experiences and consultants/academics observing patterns, but there is little research comparing different methods. The document advocates for more empirical research to determine what facilitation techniques actually work best. It then provides examples from the author's experience between 1967-1979 where different approaches were needed for different projects and contexts. The author reflects on lessons learned around communication, requirements gathering, and developer motivations. The document aims to surface what facilitation practices are most useful based on evidence and experience.
The document discusses different levels of development in groups and different approaches to discussions and decision making. It provides context on dialogue as a process aimed at finding new understanding and ways of thinking through relationships and suspending assumptions. Key aspects of dialogue discussed include allowing new ideas and content to emerge through understanding differences in perspectives, as well as creating something in common.
This document discusses various techniques for improving creativity and innovation in organizations. It argues that it is easier to change an organization's climate than its culture, and that a positive climate can help foster a more creative culture over time. Several key aspects of an organizational climate that supports creativity are identified, including providing time for idea generation, supporting new ideas, encouraging challenge and involvement, trusting relationships, playfulness, and resolving conflicts constructively. Specific techniques described for generating new ideas include brainstorming, the nominal group technique, lateral and parallel thinking, mind mapping, and metaphorming.
In 3 sentences: Groups function best when members feel part of the group, trust each other, and share common values. Effective groups sort out aims, membership, leadership, decision-making, and address feelings and conflicts openly. High-performing groups achieve synergy where the whole is greater than the sum of individual contributions through trust, flexibility, and members expressing themselves genuinely.
Conflict is inevitable and complex, involving emotions. It can be a problem if unmanaged, but an opportunity if properly managed through openness, safety, and developing conflict competence. There are two main types of conflict - relationship conflict, which involves negative emotions, and task conflict, which involves positive emotions and robust debate. Differences in personalities, preferences, styles, values, culture, knowledge, needs, and goals can all be sources of conflict. Building trust and psychological safety are important for constructive conflict. Emotions are triggered in the amygdala and modulated in the prefrontal cortex. Cooling down emotions through breathing and reframing is important for managing conflict constructively.
This document provides an overview of action research. It describes action research as a method for professionals to improve their own practice and contribute to public knowledge about their field. Action research requires systematic inquiry, action, validation of results. It positions the researcher as central to the process as they are committed to improving a meaningful purpose. While challenging, action research offers opportunities for the researcher to improve their work and contribute new knowledge through an iterative process.
The document discusses models and their relationship to reality. It notes that models are representations of reality, not reality itself, and different people may perceive the same event in different ways. Phenomenologists aim to model human experience and perceptions, rather than just observable behaviors alone. The complexity of human interactions is explored, with various meanings and realities potentially present in the same event. Navigating social situations requires consideration of multiple perspectives and realities that may be in play.

2. FLOCK THEORY
Flock Theory models the flight of birds.
Flock theory has been used to explain
cooperative evolution in human interactions.
3. JAMMING
Eisenberg defines jamming (as used by jazz musicians) as
• fluid behavioural coordination
• that occurs without detailed knowledge of personality
Preconditions: skill, structure, setting, surrender, reward risk,
engage respectfully, no dominant leadership,
autonomous group ensures influx of novel ideas
Outcomes:
• balance between autonomy and interdependence
• nondisclosive but fulfilling route to community
• closeness without self-consciousness
4. JAMMIMG VIDEO
To see what jamming looks like,
watch this video of Voxnorth improvising

5. AUTOPOIESIS (Humberto Maturana)
Autopoiesis = recursive self-reproduction of system components
An autopoietic system (e.g. a biological cell):
• is an assembly of organized bounded structures
• that uses external flows of resources and by-products
• to produce the components which, in turn,
– maintain the organized bounded structure
– that is the autopoietic structure
SO:
• resources come and go,
• components are created and may die,
BUT the structure continues through time
6. SIMULATING A FLOCK OF BIRDS
A flock exhibits many contrasts:
– It is made up of discrete birds,
yet overall motion seems fluid
– It is simple in concept
yet is so visually complex
– It seems randomly arrayed,
yet is magnificently synchronized.
– Most puzzling is the impression of intentional,
centralized control
(Reynolds 1987)
7. FLOCK OF STARLINGS
To experience
‘an impression of intentionality’,
