 Reluctance generator/motor cooling - Patent 5703421   (Site not responding. Last check: 2007-10-13)
The apparatus includes an electrical winding-free reluctance rotor having a plurality of windage controlling and heat dissipating divider or barrier elements (which are also referred-to as thermal elements in the descriptions) disposed at opposite ends and periodically along its axial length to definite a plurality of rotor cooling chamber areas.
As noted, the switched reluctance generator/motor is also found desirable for use as a two-way energy transducer in an aircraft propulsion jet engine; i.e., for use during starting of the engine and then for use in converting a portion of the engine's mechanical energy output into the aircraft's electrical energy source.
The electrical windings of the reluctance motor/generator may often be arranged to have the spacers shown at 306 and the cooling fluid escape apertures 308 and 310 located in the stator interpole spaces of the machine.

 Call Reluctance: The Dark Side of Professional Selling? Southern Business Review - Find Articles   (Site not responding. Last check: 2007-10-13)
The phenomenon of call reluctance, for the purpose of this article, is the experience of an elevated level of apprehension sometimes seemingly overwhelming, that may inhibit the number of calls a person will make, and perhaps, rendering the individual incapable of working at all.
Professors of courses such as sales and sales management need to be aware of the importance of call reluctance so that they devote appropriate attention to the subject in their classes to prevent students' being caught unaware and perhaps being blind-sided by their own experiences of this phenomenon should they become sales professionals.
Sales managers need to be tuned in to symptoms of call reluctance so that they recognize and head off its early signs and learn to deal with it in their subordinates as constructively as possible while encouraging and facilitating the subordinates' successes at every level in the shortintermediate-, and long-term.

 Reluctance, by Robert Frost (1874-1963)
  Reluctance was the last poem to be published in part three which was known as the seasonal cycle, so that the poems carried on through the summer, ending in autumn, which ended with Reluctance (Thompson 398).
Robert Frost initially wrote Reluctance because he felt that he suffered an irreparable shock, loss, and metamorphosis as a result of what he viewed as Elinor White’s rejection of him when he visited her at St. Lawrence University.
Reluctance also shows Frost’s love of the cycle of the different seasons which is why he dearly loved

 Switched Reluctance Motor Drives Information
The term became popular from the 1980s onwards, through the efforts of the first commercial exploiters of the technology, Switched Reluctance Drives Ltd. The machines are alternatively known as variable reluctance motors, reflecting the origins of the technology being derived from VR stepper motors.
Even so the first recognisable reluctance machines were built over 150 years ago, most famously by Davidson as a traction drive for an electric locomotive in 1838.
The operation of the motor where the salient poles tend to align to minimise reluctance in normal operation leads to high normal forces acting on the stator structure.

 EETimes.com - Partial Reluctance Extraction
They pointed out that partial reluctance has locality similar to capacitance, and it can be sparsified like the capacitance matrix without losing the passivity of the circuit.
By inverting the partial inductance matrix to the partial reluctance matrix, it can be found that the partial reluctance matrix has similar sparsity to capacitance matrix, and it is much sparser than the partial inductance matrix.
Reluctance coupling is local because reluctance is shielded by neighboring conductors, while inductance has no such effect and is mainly a function of distance between wires.

 The Wrong Kind of Reluctance: What We Can't Learn from the Air Campaign in Kosovo   (Site not responding. Last check: 2007-10-13)
I shall also consider briefly a kind of “strategic reluctance” evident in the dialogue surrounding Kosovo, that is, a perceived unwillingness to take certain risks or to make strong commitments whether from the political pulpit or on the battle grounds.
Specifically, I wish to consider how the morality of another form of reluctance, a kind of “principled restraint,” helps frame the discussion of when and how military commitments ought to be carried out.
Outside parties should be reluctant to intervene (even on behalf of a beleaguered people), for that is to meddle artificially with war's “natural corrective” powers.

 Question Reluctance Sabotages Sales
Question Reluctance is equally prevalent among salespeople, yet its rarely discussed or addressed.
Classic symptoms of Question Reluctance include avoiding asking a question altogether, waiting until the end of a sales call to finally ask what you truly need to know, framing questions so indirectly that prospects get confused, and failing to ask clarifying follow-up questions to ensure that you and the prospects are 'on the same page'.
Question reluctance is like having one foot on the brake pedal while the other is on the gas.
