Back Matter | From the Archives of Lapham’s Quarterly
Valentine’s Day is almost here, but in a letter sent on April Fools’ Day in 1838, Abraham Lincoln—born on this day in 1809—showed himself to be not much of a romantic. He declared that he would never marry “for this reason—I can never be satisfied with anyone who would be blockhead enough to have me.” He married Mary Todd four years later. Mary Owens, who may have been the woman maligned in the letter below, said of her suitor, “I thought Mr. Lincoln was deficient in those little links which make up the chain of woman’s happiness—at least it was so in my case.”

Abraham Lincoln Loses the Girl

Without apologizing for being egotistical, I shall make the history of so much of my life as has elapsed since I saw you the subject of this letter. And, by the way, I now discover that in order to give a full and intelligible account of the things I have done and suffered since I saw you, I shall necessarily have to relate some that happened before.

It was, then, in the autumn of 1836 that a married lady of my acquaintance, and who was a great friend of mine, being about to pay a visit to her father and other relatives residing in Kentucky, proposed to me that on her return, she would bring a sister of hers with her, on condition that I would engage to become her brother-in-law with all convenient dispatch. I, of course, accepted the proposal, for you know I could not have done otherwise had I really been averse to it; but privately, between you and me, I was most confoundedly well pleased with the project. I had seen the said sister some three years before, thought her intelligent and agreeable, and saw no good objection to plodding life through hand in hand with her. Time passed on, the lady took her journey, and in due time returned, sister in company, sure enough. This astonished me a little, for it appeared to me that her coming so readily showed that she was a trifle too willing, but on reflection it occurred to me that she might have been prevailed on by her married sister to come, without anything concerning me ever having been mentioned to her, and so I concluded that if no other objection presented itself, I would consent to waive this. All this occurred to me on hearing of her arrival in the neighborhood—for, be it remembered, I had not yet seen her, except about three years previous, as above mentioned. In a few days we had an interview, and although I had seen her before, she did not look as my imagination had pictured her.

Abstract: There exist many dental surgery such as orthognathic surgery and an implant operation. Jaw deformity is one of the dental diseases such as an abnormality of occlusion and facial distortion in the shape. To treat jaw deformity, the osteotomy is carried out by human hands. However, drilling a jawbone accurately by oral surgeons is difficult. Recently, surgical robots are attracting attention in the medical field. The researches of surgery supporting systems have been carried out. They have possibilities to avoid unexpected accidents in the surgery, a hands shake and so on. The improvement of the minimally invasive surgery can be expected, thanks to robotic technology. The purpose of this research is the design and development of master-slave dentistry and oral surgery assisting robot. By implementing acceleration based bilateral control, haptic information can be communicated. Moreover, the proposed robot has the serial-parallel hybrid mechanism that can obtain the advantages of a serial mechanism and a parallel mechanism. In this paper, the mechanism of the proposed robot is explained and the performance of the proposed robot is validated by experiments.

Since 1987 the American Society of Heating and Refrigeration Engineers has lead development of the de facto standard for campus building automation systems 135 BACnet® – A Data Communication Protocol for Building Automation and Control Networks. This title supports the #WiseCampus transformation in two important ways:

  • It defines data communication services and protocols for computer equipment used for monitoring and control of HVAC&R and other building systems
  • It defines an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

BACNet Committee: ASHRAE SSPC 135

Since the late 1970’s these systems have grown from single building control networks for environment air into multi-building campus-wide systems that conform to the ISO model of layered communication architecture.   Every large research university has long since installed facility management unit that monitors and controls points such as outdoor air intake, wet-bulb temperature, occupancy load, elevator action, time of day, outdoor lighting etc.    The University of Michigan, for example, monitors and controls nearly 1 million control points on its 6 square mile Ann Arbor campus.

The ASHRAE 135 technical committee has released a consultation on addendum cd regarding cipher suite application security profiles.  Several redlines are now open for public consultation and may be found here:

ASHRAE Public Review Drafts Standards

Consultation on several titles is open until March 20th.

This title, and several others in the ASHRAE catalog, are on the standing agenda of our Energy 200 and Energy 400 colloquium.  See our CALENDAR for the next online meeting; open to everyone.
