misclose (plural miscloses)

1. (surveying) The discrepancy between the starting point the endpoint of the shape reconstructed from the measured dimensions and bearings of a boundary.
   • 1989, National University of Singapore, Publications and Theses, page 21:

     The use of the ratio of the linear misclose to the total length traversed as an expression of traverse accuracy has been known to be theoretically weak since sampling distributions are unknown.

   • 1994, Agricultural Census, 1993: Technical Report, page 19:

     The program also calculated the misclose ratio as a check to see if the garden measurement data had been taken accurately and entered correctly.

   • 2017, John Walker, Joseph L. Awange, Surveying for Civil and Mine Engineers, page 18:

     A misclose assessment should be undertaken to verify that forward and backward runs of a levelling travers, including any individual bays, are within the maximum allowable misclose.

2. (civil engineering, by extension) The degree to which the model of the forces acting on a structure fail to account for the observed shape of that structure.
   • 1974, Institution of Civil Engineers (Great Britain), Proceedings - Volume 56, Part 1, page 191:

     Of these papers it is interesting to note that the shape profile analysed according to the Anwar and Binnie methods contained minor miscloses under static conditions, whereas the Harrison computer-orientated method appears to be satisfactory.

   • 1983, L. J. Morris, Instability and plastic collapse of steel structures, page 57:

     Having computed three miscloses from three initial guesses, Newtonian iteration is used to improve the guessed values in a semi-automatic manner.

   • 1997, A. E. Kilpatrick, Balamuthu Vijaya Rangan, Curtin University of Technology. School of Civil Engineering, Deformation-control analysis of composite concrete columns, page 39:

     This process was repeated for all nodes along the column and the resulting deflection (misclose) at the top of the column of -0.298 mm indicated that the chosen trial value of N was incorrect.

misclose (third-person singular simple present miscloses, present participle misclosing, simple past and past participle misclosed)

1. (surveying) To cause or exhibit a misclose.
   • 1991, Romanus Nnubia Asoegwu, Professional Papers on Surveying Practice in Nigeria, page 22:

     In some surveys angles of a traverse are known to misclose up to 5° (five degrees) but the traverse is adjusted.

   • 1997, Compass & Tape - Volumes 13-16, page 23:

     Since the outer loop also contains the blundered angle, it should come as no surprise that it also miscloses by 2 degrees.

   • 2003, Paul A. Cuomo, Surveying Principles for Civil Engineers, page 47:

     The traverse miscloses by +0.44 ft in latitudes and +0.20 ft in departures. Consequently, to achieve closure, (+) latitudes must be reduced, (-) latitudes must be increased, (+) departures must be reduced, and (-) departures must be increased.

2. (more generally) To fail to loop back to the starting point.
   • 1962, The Australian Journal of Science, page 371:

     Looked at as a single structure (Figure 2), the Tethyan Torsion Zone is a belt generally 1000 km or more wide, and a total length of some 40,000 km, which creeps southwards as it is followed eastward round the globe, so that the zone miscloses its own beginning by about 60° (some 7000 km.)

   • 1995, Roman Teisseyre, Theory of Earthquake Premonitory and Fracture Processes, page 509:

     Another definition can be sometimes more useful: consider a closed loop which becomes broken and misclosed due to anholonomic transformation.

3. To close improperly; to fail to shut properly.
   • 1952, Hitachi Review - Issues 1-7; Volume 0, page 55:

     when the phases of both circuits synchronize and prevents the misclosing when the system disturbance is not in a proper condition to close.

   • 1981, Luther Yates Gore, The Engineer in the Fabric of Responsibility, page 101:

     Once more the ordinary person's common sense is roughly adequate to understand that since hydraulically misclosed doors leak or " bleed" continually, the chances of a catastrophic door blow-out and subsequent decompression are lessened.

   • 2019, Shuai Han, Liang Ye, Weixiao Meng, Artificial Intelligence for Communications and Networks, page 31:

     Environment type: temperature, humidity, electromagnetic, current exceed the threshold or change too much; typical misoperations such as mis-opening, misclosing, etc.

4. To close (a deal) in error.
   • 1993, Andoni Lizardy, Closing Tactics, page 90:

     If you fail to qualify the client's needs well, you may make a poor presentation." "Or misclose the customer," commented another seller.
