a hydrogen atom, and releasing energy, or an autonomous robot that automatically reroutes internal electrical energy to recharge batteries without an
indication of the remaining charge needed to maintain a minimum threshold for operations of all its subsystems. The yelling for assistance is a general
request directed to anyone, regardless of language. The autonomous robot’s
rerouting of energy may be based on elapsed time since last recharge, or a
software algorithm that relies on internal sensor inputs to estimate reserve
capacities of its rechargeable batteries. A Type 1 interaction is initiated from
within. In contrast, a Type 2 interaction eliminates (or discharges or “sends”)
EMMI due to some external receipt of EMMI. Examples of Type 2 interactions include the person responding to the yelling for help. Type 1 interactions reflect the internal needs or intentions of an entity, for example, the
self-initiated requirements for survival. Type 1 interactions are in response
to internal processes, the mechanically induced self-regulation for fulfilling
basic needs. Type 2 interactions are the responses to external stimuli, the
simultaneous or reflexive reactions based on are capabilities within the entity’s structure. Regardless of the type of interaction, the mechanical processes
that carry out the actions of the “send” and “receive” functions are limited
by the entity’s capacity to initiate a “send” or respond to a “receive.” Further,
the mechanics of interaction also preserve the constraints of the entities.
The  architecture of the entity and the mechanism for interaction are constrained by their design and implementation. Therefore, interacting entities
are subject to limitations, conditions, and constraints.
Limitations describe the extremes of operability of an entity at its boundaries (the physical extend of an entity). Limitations are methodological or procedural schemas that either define or signify intended extremes. Limitations
can be organization or mechanistic, procedural (rules and policies), and social
(customary and acceptable behaviors). Limitations are sometimes described
as conditions of boundaries (i.e., boundary conditions). Once the limitations
are instantiated in the entity, they form an immutable structure. For example,
the physical design of some products, for example, a single-handset telephone, is optimized for a single user. The limitations are imposed through
both the design and technology which combine to provide a distance at
which a voice can be heard (from the perspective of both the person speaking
and the person listening). Limitations can also be thought of as the budget
earmarked and the schedule determined for a project. The project costs shall
not exceed $10 million and the deliverables are due no later than 2 years from
the start of a fully executed contract. These are limitations agreed to by the
parties, stated in the contract between the parties, and enforced by penalties.
The parties to the contract are limited by the agreement. Limits apply to what
can be done versus boundaries that apply to the physical extent of entities.
Within the limitations of the contract, constraints are the apportionments
of money distributed to the tasks along with its designated schedule.
Allocations impose conditions on objects and processes. The concept of
interaction captures the observation that an entity or agent (for another
