Cowan, Nelson. "Metatheory of storage capacity limits." Behavioral and Brain Sciences 24, no. 1 (February 2001): 154–76. http://dx.doi.org/10.1017/s0140525x0161392x.

Abstract:

Commentators expressed a wide variety of views on whether there is a basic capacity limit of 3 to 5 chunks and, among those who believe in it, about why it occurs. In this response, I conclude that the capacity limit is real and that the concept is strengthened by additional evidence offered by a number of commentators. I consider various arguments why the limit occurs and try to organize these arguments into a conceptual framework or “metatheory” of storage capacity limits meant to be useful in future research to settle the issue. I suggest that principles of memory representation determine what parts of the representation will be most prominent but that limits of attention (or of a memory store that includes only items that have been most recently attended) determine the 3- to 5-chunk capacity limit.

Abstract:

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed.

Abstract:

The objective of the study was to determine the limits of economic justification for irrigation system capacity use. The first step was focused on determining the lower limit of capacity use by comparing the economic effects of irrigation with the costs of the irrigation system use. In addition, while determining these limits the need was stressed to consider the economic effects of irrigation by optimizing the production structure and the modes for limit determination under irrigation and non-irrigation conditions. Eventually, the empirically verified possibility stating that this limit may be determined by comparing the water processing prices with its cost price is given. The limit was found to be the point at which these two prices equalize.

Abstract:

Cowan's review shows that a short-term memory limit of four items is consistent with a wide range of phenomena in the field. However, he does not explain that limit, whereas an existing theory does offer an explanation for capacity limitations. Furthermore, processing capacity limits cannot be reduced to storage limits as Cowan claims.

Abstract:

Cowan argues that the true short-term memory (STM) capacity limit is about 4 items. Functional neuroimaging data converge with this conclusion, indicating distinct neural activity patterns depending on whether or not memory task-demands exceed this limit. STM for verbal information within that capacity invokes focal prefrontal cortical activation that increases with memory load. STM for verbal information exceeding that capacity invokes widespread prefrontal activation in regions associated with executive and attentional processes that may mediate chunking processes to accommodate STM capacity limits.

Abstract:

Using explicit memory measures, Cowan predicts a new circumstance in which the central capacity limit of 4 chunks should obtain. Supporting results for such an experiment, using continuous old-new recognition, are described. With implicit memory measures, Cowan assumes that short-term repetition priming reflects the central capacity limit. I argue that this phenomenon instead reflects limits within individual perceptual processing modules.

Abstract:

Most of the digital data transmitted are carried by optical fibres, forming the great part of the national and international communication infrastructure. The information-carrying capacity of these networks has increased vastly over the past decades through the introduction of wavelength division multiplexing, advanced modulation formats, digital signal processing and improved optical fibre and amplifier technology. These developments sparked the communication revolution and the growth of the Internet, and have created an illusion of infinite capacity being available. But as the volume of data continues to increase, is there a limit to the capacity of an optical fibre communication channel? The optical fibre channel is nonlinear, and the intensity-dependent Kerr nonlinearity limit has been suggested as a fundamental limit to optical fibre capacity. Current research is focused on whether this is the case, and on linear and nonlinear techniques, both optical and electronic, to understand, unlock and maximize the capacity of optical communications in the nonlinear regime. This paper describes some of them and discusses future prospects for success in the quest for capacity.

Abstract:

Wind/Photovoltaic hybrid generating system can alleviate power fluctuations caused by the single source and improve the system power supply reliability. In the stage of planning, the grid-connected scheme and capacity limit calculation problem is needed to solve. Under different schemes, the capacity limit is different. This paper established an optimization model of capacity limit of wind/photovoltaic power station, introduced the tracking center trajectory interior point algorithm to solve capacity limit, and demonstrated the validity of the proposed method by a simulation of IEEE 30-node system considering the reserve capacity, and concluded that capacity limit is larger when Wind/Photovoltaic is parallel in heavy load nodes. This method can provide reference for practical system of calculating capacity limit of wind farm or photovoltaic power station and is feasible.

Abstract:

The existed concrete column reinforced by external steel tube is a common reinforcement technique and widely used in engineering. However, the computational theory on bearing capacity of the reinforced structure is insufficient at present. In the condition that the existed column concrete before completely unloading is reinforced or the initial stress level is low, the mechanics characteristics of reinforced components were analyzed based on the limit equilibrium method, and then the computational equations of the bearing capacity subjected to axial loading after the short column pier reinforced structure had been deduced. Comparing the calculation results with the correspondent experimental data shows that the deduced equation can provide reasonable results for predicting the axial bearing capacity, which provides a support for the computation of the bearing capacity for the reinforcement pier in practice.

Limit bearing capacity of foundation soil was studied in the paper using slip line method. Slip line results are found to be consistent with the results calculated by Terzaghi theoretical formula and Hansen theoretical formula. Then the influence of factors such as cohesion and friction angle is studied under complete smooth or complete tough conditions. The results show that in a certain range, limit bearing capacity of foundation increases with the increase of C0, Φ. Limit bearing capacity of foundation under complete smooth condition is lower than the complete tough one.

Abstract:

On August 1, 1996, the speed limit on certain sections of Michigan freeways increased from 104.6 to 112.6 km/h (65 to 70 mph). This was due to the Michigan Legislature passing a bill that permitted the governor of Michigan to increase the speed limit given that a study be conducted to determine the effects on safety and capacity. Michigan State University conducted the study that determined the effects of increasing the speed limit on certain sections of highway. This study examined not only freeways that were increased to 112.6 km/h (70 mph), but also the speeds and capacities of freeway sections where the speed limit was not increased. Different types of speed analyses were done in comparing the test sections where the speed limits were raised with the control sections where the speed limits were not raised. The analysis also included categorizing the roadway into intercity and recreational routes to determine the effect on speeds for different uses in road use. The speed data also were broken down into different vehicle types. A preliminary accident analysis was performed on the control and test sections to determine the effect of increasing the speed limit on accidents. It was proved that increasing the speed limit on certain sections of freeway in Michigan had little effect on the change in speed and capacity on both test and control sections.

Abstract:

Cowan assumes that chunk-based capacity limits are synonymous with the essence of a “specialized STM mechanism.” In a single experiment, we measured the capacity, or span, of long-term memory and found that it, too, corresponds roughly to the magical number 4. The results imply that a chunk-based capacity limit is not a signature characteristic of remembering over the short-term.

Full text

Abstract:

A two-level seismic assessment procedure for reinforced concrete frame buildings is presented. The intent of the procedure is to determine the risk, in terms of annual probability of exceedance, associated with two limit states, namely a serviceability limit state and a survival, or ultimate, limit state. The serviceability limit state is determined by elastic response calculation, but the survival limit state analysis attempts to identify the strength and ductility of the critical collapse mechanism, and hence its probability of exceedance by comparison with reference spectra. The basis for identifying the critical collapse mechanism is a modified form of capacity design principles which allows local element failure provided overall structural integrity is not jeopardized.

Abstract:

This paper presents a method of time optimal path planning under kinematic, limit heat characteristics of DC motor and dynamic constrain for a 2-DOF wheeled. Firstly the shortest path is planned by using the geometric method under kinematic constraints. Then, in order to make full use of motors capacity we have the torque limits under limit heat characteristics of DC motor, finally the velocity limit and the boundary acceleration (deceleration) are determined to generate a time optimal path.
