Abstract: A block oriented random access memory (BORAM) is disclosed as comprising a plurality of memory arrays of metal-nitride-oxide semiconductor (MNOS) memory elements. Each memory array includes a plurality of the MNOS memory elements disposed in rows and columns, and serial or sequential means such as a shift register for writing and reading data to and from the memory elements through column conductors associated with each column of the memory elements. A temporary storage means such as a latch is inserted between each stage of the shift register and the column conductor, whereby a multiplexing function can be performed between the stage outputs of the shift register and the columns of the memory elements. Address means is provided for the rows of memory elements, whereby a row may be selected for entry of data through its associated column conductor. In one illustrative embodiment, a plurality of such assemblies is assembled into a block capable of being separately addressed, wherein each such assembly is capable of storing one bit of a multi-bit word of data. In turn, a plurality of such blocks is assembled to form the block oriented random access memory, wherein each such block may be randomly accessed, and the data therein sequentially read and written.

Abstract: The literature on categorized data has been primarily concerned with the analysis of contingency tables. In the usual situation, it is assumed that we have sampled a multinomial population in which the classes are described according to two or more categories and the data are summarized in a contingency table with corresponding dimension. Specifically, in a two-way table with r rows and c columns, it is assumed that the data in the rc cells follow a multinomial distribution with cell probabilities 7iij . The usual analysis consists of estimating the rii and testing certain hypotheses on these parameters. In this paper, we consider situations in which the data have been taken from such a multinomial population, but, because of partial categorization of some of the observations, the summary is in the form of two or more related tables. For example, we may have data ni;, i = 1, 2; j = 1, 2, 3, in a 2 X 3 table from a population with six classes described by two categories with two and three classes, respectively. Let us assume that in addition, we have data mij , i = 1, 2; j = 1, 2, in a 2 X 2 table whose description is derived from the original table in the sense that the first two column classifications have been combined. For the purpose of gaining additional precision in the analysis, it is desired to combine the information in the two sets of data. If the data nii are assumed to follow a multinomial distribution with parameters irij, = 1, 2; j = 1, 2, 3, then the data mij are also multinomial with parameters (7ril + 7r12), 713 , (X21 + r22), r23 . Assuming that the two sets of data are independent, we may obtain maximum likelihood estimates of the parameters from the combined data using the procedure described by Hocking and Oxspring [1971] (hereafter abbreviated (HO)). The purpose of this paper is to illustrate the application of (HO) to the estimation of parameters from contingency data when, in addition to the basic table, we have tables which arise because row and/or column classifications have been combined. In some cases, the partially categorized data arises because of the nature of the data and the manner in which it was collected. Alternatively, the experiment may have been intentionally designed

Abstract: The disclosure relates to a high density, high speed random access memory (RAM) which uses one transistor per storage cell. The cells are in a matrix of rows and columns, and a sense and refresh amplifier is located in the center of each column. Row address circuitry selects one row to be read out. The data stored in the cells in the selected row are transferred to the sense and refresh amplifiers, and column address circuitry selects one of the rows to be coupled to circuitry which performs both input and output functions.

Abstract: In most cases, values are tabulated in the customary manner- ten on a line. In some tables, the second column gives the first few places which apply to all the entries in that row. When an entry has a bar placed over it, the value heading the next row should be applied. The tables computed on a digital electronic computer which works with an accuracy of at least seven significant places. In some case, e.g. when very large exponents occurred in the computation, computation at double this precision was used.

Abstract: In this paper, the functional capabilities and economic features of the Relational Data Management System (RDMS) are discussed. RDMS is a generalized on-line data management system written in PL/1 for the Multics operating system.The basic concepts of RDMS are introduced and the similarities between the conventional file concept and the relation concept are discussed. A data-base is shown to be a set of relations. By generalizing the concept of field to be a property of the data-base, and by labeling relations with the names of their columns (fields), relations of a data-base may be implicitly linked by virtue of having a common column or field name (the dataclass name). On-line commands for operations on two such relations which yield a third result relation are illustrated. Other facilities of RDMS, such as computational, report-generation, and query-report packages are discussed.In RDMS, the relation concept is implemented as a matrix of reference numbers which refer to character string datums which are stored elsewhere in distinct dataclass files. In addition to significant storage savings, this allows a single representation-independent logical interface to the storage and access of character string data.RDMS was developed from graduate work done at M.I.T. by L. A. Kraning and A. I. Fillat in 1970 and is now being used by the administrative departments at M.I.T.

Abstract: A modular control system is provided for a gas panel of the type having an array of row wires and column wires that form light emitting cells at their crossover points. A row counter and a column counter provide selection signals for entering characters sequentially on the panel. The counters provide borrow and carry signals to components that control the display. Thus, the control operates without regard to the actual size of the display and provides a modular construction for displays of various sizes.

Abstract: A lifting apparatus of the type having a number of columns supporting a load platform each column driven by an electrical, polyphase current motor whereby sensors on each column, for example potentiometers, produce a signal indicating the height of that column. The signals are applied to a comparator which in turn provides an output to one or more electronic switches, such as a triac or thyristor having a diode connected in parallel with it for conducting current in an opposite direction, each such switch connected to a winding of a motor to control the current applied so as to reduce any difference in height among the columns.

Abstract: The new rules for concrete column design which appear in CP110 are discussed. The discussion centers around a comprehensive flow chart prepared by the author to facilitate the interpretation of CP110, and which is included in the article. With the aid of the flow chart, comments are made on the various decisions that are involved, these include whether the column is braced or unbraced, whether it is slender or short, its external dimensions, whether the column is lightly loaded and whether it carries a load at large eccentricity. Tables are included of n/bh (direct load divided by external dimensions) values for unreinforced and 8% steel reinforced columns for various values of the factor "K". These may be used to prepare charts which may be utilized to readily calculate the K factor for any column in order to establish the most economic design. /TRRL/
