91,000 | Redundancy with ring topology, without additional hardware, is no problem for Sercos. Cable breaks in a ring configuration are recognized within 25μs. | SERCOS III | 0.780709 |
91,001 | Sercos III also supports an operating system and hardware platform independent “Soft Master”, using a completely software-based stack for the master interface. Since the maximum jitter in such a configuration is dependent upon the operating system of the Master, the maximum jitter may be set by a variable for the Serco... | SERCOS III | 0.780709 |
91,002 | A ring topology simply closes the network by attaching the unused port on the last device in a ring back to the unused port on the Master. When the Sercos III Master senses that a ring exists, it sets up two counter-rotating telegrams.

91,003 | They can be combined into a dual stack master.

91,004 | Since the redundancy feature of Sercos III will reconfigure the network in a bump-less manner (responding in less than one cycle), no disruption of network transmission will occur.

91,005 | UC frames may only enter a Sercos III network through a Sercos III-compliant port. This can be achieved two different ways.

In a network configured in ring topology, the ring can be tempora... | SERCOS III | 0.780709 |
91,006 | A line topology is the simpler of the two possible arrangements and provides no redundancy. However, this configuration saves the cost of one cable.

91,089 | This factor holds that organizations that are reliable and accountable are those that can survive (favored by selection). A negative by-product, however, of the need for reliability and accountability is a high degree of inertia and a resistance to change. A key prediction of organizational ecology is that the process ... | Organizational ecology | 0.780674 |
91,090 | Organizational ecology is concerned with the capacity of the environment to support organizations and the rate of growth and decline of organizations within the environment. Each of these forces is a part of what is called Organizational Mortality. | Organizational ecology | 0.780674 |
91,091 | Organizational ecology focuses on how social (community) forces affect: rates of creation of new organizational forms rates of demise of organizations and organizational forms the rates of change in organizational forms. | Organizational ecology | 0.780674 |
91,092 | 11) provide a more Lamarckian perspective. Another important difference concerns the question: What is selected by the environment-- 'organizational forms', as in organizational ecology, or 'routines' as in the evolutionary economics literature? Authors like Joel Baum and Arjen van Witteloostuijn have argued for the po... | Organizational ecology | 0.780674 |
91,093 | Organizational ecology can be usefully compared with evolutionary theories in economics (e.g. Nelson & Winter, 1982). Hannan and Freeman also note the influences of biological ecology and economic evolution on their population ecology model (specifically Elton, 1927; Durkheim, 1947; Hawley, 1950; and Hutchison, 1959). ... | Organizational ecology | 0.780674 |
91,094 | Organizational ecology also predicts that the rates of founding and mortality are dependent on the number of organizations (density) in the market. The two central mechanisms here are legitimization (the recognition or taken-for-grantedness of that group of organizations) and competition. Legitimization generally incre... | Organizational ecology | 0.780674 |
91,095 | The community level is the functionally integrated system of interacting populations. The population level is the set of organizations engaged in similar activities. The organization level focuses on the individual organizations (some research further divides organizations into individual member and sub-unit levels). W... | Organizational ecology | 0.780674 |
91,096 | Organizational ecology (also organizational demography and the population ecology of organizations) is a theoretical and empirical approach in the social sciences that is considered a sub-field of organizational studies. Organizational ecology utilizes insights from biology, economics, and sociology, and employs statis... | Organizational ecology | 0.780674 |
91,097 | The invariant bilinear map {\displaystyle } is extended to the whole superalgebra to define the (graded) Lie bracket : g × g → g {\displaystyle :{\mathfrak {g}}\times {\mathfrak {g}}\rightarrow {\mathfrak {g}}} , where the Lie bracket of anything in M {\displaystyle M} with anything is zero. The dimensions of the irre... | Super Minkowski space | 0.78067 |
91,098 | On Minkowski space, there are no-go theorems which prohibit such theories from being interesting. If one doesn't wish to consider such theories, this gives upper bounds on the dimension and on N {\displaystyle {\mathcal {N}}} . For Lorentzian spaces (with signature ( − , + , ⋯ , + ) {\displaystyle (-,+,\cdots ,+)} ), t... | Super Minkowski space | 0.78067 |
91,099 | More mathematically, any representation of the superalgebra contains fields with spin greater than 2. Theories that consider such fields are known as higher-spin theories. | Super Minkowski space | 0.78067 |
