SAMICS: Input data preparation

The Solar Array Manufacturing Industry Costing Standards (SAMICS) provide standard formats, data, assumptions, and procedures for estimating the price that a manufacturer would have to charge for the product of a specified manufacturing process sequence. A line-by-line explanation is given of those standard formats which describe the economically important characteristics of the manufacturing processes and the technological structure of the companies and the industry. This revision provides an updated presentation of Format A Process Description, consistent with the October 1978 version of that form. A checklist of items which should be entered on Format A as direct expenses is included

New input data for synthetic AGB evolution

Analytic formulae are presented to construct detailed secular lightcurves of both early asymptotic giant branch (AGB) and thermally pulsing AGB stars. They are based on an extensive grid of evolutionary calculations, performed with an updated stellar evolution code. Basic input parameters are the initial mass between 0.8 and 7 solar mass, metallicity of 0.0001, 0.008, 0.02, and the mixing length theory (MLT) parameter. The formulae allow for two important effects, namely that the first pulses do not reach the full amplitude, and hot bottom burning (HBB) in massive stars, which are both not accounted for by core mass - luminosity relations of the usual type. Furthermore, the dependence of the effective temperature and a few other quantities characterizing the conditions at the base of the convective envelope, which are relevant for HBB, are investigated as functions of luminosity, total and core mass for different formulations of the convection theory applied, MLT or Canuto & Mazzitelli's theory.Comment: Accepted for A&

Computer supported estimation of input data for transportation models

Control and management of transportation systems frequently rely on optimization or simulation methods based on a suitable model. Such a model uses optimization or simulation procedures and correct input data. The input data define transportation infrastructure and transportation flows. Data acquisition is a costly process and so an efficient approach is highly desirable. The infrastructure can be recognized from drawn maps using segmentation, thinning and vectorization. The accurate definition of network topology and nodes position is the crucial part of the process. Transportation flows can be analyzed as vehicle’s behavior based on video sequences of typical traffic situations. Resulting information consists of vehicle position, actual speed and acceleration along the road section. Data for individual vehicles are statistically processed and standard vehicle characteristics can be recommended for vehicle generator in simulation models

A pattern language for service input data provisioning.

A common practice in service-orientation is the creation of a composite service by combining a set of other services. As discussed in this article, the orchestration of services to construct a new service requires several service interactions. This is why the construction of a composite service can be a complex and time-consuming task. Some services in a service composition can have the role of providing other services with (additional) input data. The pattern language in this article can help to design the service interactions that are needed for provisioning input data.

Simplified system displays complex curves corresponding to input data

Cathode ray oscilloscope displays curves or contours of complex shapes corresponding to sets of x,y coordinates. It requires few storage facilities and produces a rapid display of complex curves with a fewer number of commands than previous systems

Longevity and Lifetime Labor Input: Data and Implications

Recent growth theories have utilized the Ben-Porath (1967) mechanism according to which prolonging the period in which individuals may receive returns on their investment spurs investment in human capital and cause growth. An important, though sometime implicit implication of these models is that total labor input over the lifetime increases as longevity does. We propose a thought experiment to empirically evaluate the relevancy of this mechanism to the transition from “stagnation” to “growth” of the nowadays developed economies. Specifically, we estimate the expected total working hours over the lifetime of nine consecutive cohorts of American men born between 1840 and 1920. Our results show that despite a gain of almost 9 years in the expectations of life at age 20, the expected total working hours over the lifetime have declined from more than 117,000 hours to less than 90,000 between the oldest and the youngest cohorts. We conclude that the Ben-Porath mechanism have had a lesser effect than previously thought on the accumulation of human capital during the growth process.longevity, human capital, hours-worked
