Geodesy by radio interferometry: Effects of atmospheric modeling errors on estimates of baseline length
- 1985

Ingår i: Radio Science. - 0048-6604 .- 1944-799X. ; 20:6, s. 1593-1607
-
Tidskriftsartikel (refereegranskat)abstract
- Analysis of very long baseline interferometry data indicates that systematic errors in prior estimatesof baseline length, of order 5 cm for ~8000-km baselines, were due primarily to mismodeling of theelectrical path length of the troposphere and mesosphere ("atmospheric delay"). Here we discussobservational evidence for the existence of such errors in the previously used models for the atmosphericdelay and develop a new "mapping" function for the elevation angle dependence of this delay. Thedelay predicted by this new mapping function differs from ray trace results by less than ~5 mm, at allelevations down to 5° elevation, and introduces errors into the estimates of baseline length of •

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report for the company in question (the Volvo Truck Company) which is financed by the company and partly also by a research foundation. It is a matter of a work that in this particular case were carried out during nine years in a number of experimental workshops located outside the Chalmers University of Technology. These workshops were financed by the Volvo Automobile and Truck companies. This achievement, as the final contribution to the Swedish automotive industry after having already treated this research field/problem area for more than two decades before this particular period if time (involving several junior and senior research competencies, as well as industrial and governmental foundings). Specifically (and as stated for the previous report), this publication explains how the authors dealt with the product architecture and product variation of the automotive products disassembled, which proved to necessary to be carried out in one of the experimental workshops (several complete automobiles and one heavy truck chassis were disassembled combined with having product data accessible in form of paper print-outs as well as by appropriate computer connections to the two Volvo companies etc.). That is, by using a special sort of “design analysis by means of axonometric hand-drawn illustrations” (see a conference contribution from 1992 that also is registered and available as o PDF-document at Chalmers Public Library (CPL) (a self-developed method found out together with a junior research competency from the School of Architecture at Chalmers).

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report ("avnämarrapport" in Swedish) for a research foundation (Styrelsen för Teknisk Utveckling, Stockholm). A comment: Publishing consumer reports was the praxis during this (early) period of time at Chalmers University of Technology, as well as probably at some other universities. This means that frequent and vast academic publication by means of e.g. conference papers and refereed contributions to scientific journals was almost unheard of. At least so for some of the applied science disciplines. However, today are the situation indeed very different (i.e. earlier was the publication in many respects focused on trying to satisfy the executive administrator the research foundation in question etc.). To be more precise, this early praxis was definitively the case for the research and development work carried out at the Department of Transportation (a broadly applied science discipline), which was characterized by more practical strives to e.g. engineer research results. Rather than relying on truer scientific efforts in a narrower sense. Functional satisfaction (i.e. something engineered work as planned instead verification/falsification of a hypothesis) was judged as being a primary aim of this research and development work. Therefore are (in the context of the publications registered in Chalmers Public Library CPL) the author making distinctions between consumer reports, on one hand. And, one the other hand, reports and preprints (manuscripts), while instead the academically orientated publications are various sort of scientific contributions presented at conferences or published in scientific journals (actually it is somewhat more complex, but further explanations are omitted here). The consumer reports were aimed at a various external organization with who the authors cooperated, and these are in many cases not available in PDF format to be easily read by logging in at CPL. This particular approach has judged as being fair/relevant fair in order to mirror of work conducted by the author or authors during the passing decades. Besides, the competencies at Chalmers Library, who actually have been very helpful, have not managed to provide appropriate answers to the various questions implied being at hand just above (this despite trying to get hold of such answers, hence this very comment).

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report for the company in question (the Volvo Automobile Company) which is financed by the company and partly also by a research foundation. It is a matter of a work that in this particular case were carried out during nine years in a number of experimental workshops located outside the Chalmers University of Technology. This system of interrelated drawings was in the developed in the experimental workshop an formed the basis for the assembly work conducted at the Volvo Uddevalla plant (it explains/illustrated a so-called assembly-oriented product structure, which is something very different from the common Volvo companies so-called Function Group Register that instead is a design-oriented product structure) (see the authors' other publication). These workshops were financed by the Volvo Automobile and Truck companies. This achievement, as the final contribution to the Swedish automotive industry after having already treated this research field/problem area for more than two decades before this particular period if time (involving several junior and senior research competencies, as well as industrial and governmental founding). This system of interrelated drawing was developed in one of the experimental workshops together with e.g. operators (as well as senior research competency within vocational learning and training from Gothenburg University) from the temporary learning and training workshop predating the Volvo Uddevalla plant, and thereafter used for full-scale product purpose in the completed assembly plant. They were formalised by an information system used for such purposes. Thus, it is fair to state that these particular drawings were validated at an industrial scale, expressing an assembly-oriented product structure for the Volvo 700-model (note that the system represents years and years of work from both our and others side) (we were helped out by an architect from Chalmers University of Technology, who worked for years in one of the experimental workshops thereby helping us out to formalise the decomposed automotive products (see the authors’ other publications). Comment 1: See a conference contribution from 1992 that also is registered and available as o PDF-document at Chalmers Public Library (CPL) (a self-developed method found out together with e.g. a junior research competency from the School of Architecture at Chalmers as well as by getting helped out på the senior research competency withing vocational learning and training).

- This was a work carried out by the authors in parallel with the at this period of time ongoing work at the Department of Transportation and at the Volvo Automobile Company’s assembly plant in Uddevalla. In this case were modularization and synchronization of large parts in focus (as this was a sort of common denominator for our practical and theoretical development at the Department of Transportation).

Implementations of the Convolution Operation
- 1982
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The first part of this article surveys a large number of implementations of the convolution operation (which is also known as the sum-of-products, the inner product) based on a systematic exploration of index permutations. First we assume a limited amount of parallelism in the form of an adder. Next, multipliers and RAM:s are utilized. The so called distributed arithmetic follows naturally from this approach.The second part brings in the concept of pipelining on the bitlevel to obtain high throughput convolvers adapted for VLSI-design (systolic arrays). The serial/parallel multiplier is analyzed in a way that unravels a vast amount new variations. Even more interesting, all these new variations can be carried over to serial/parallel convolvers. These novel devices can be implemented as linear structures of identical cells where the multipliers are embedded at equidistant intervals.

- The four lowest formant frequencies were measured in eight members of the bass section of a good amateur choir under two conditions: (1) when reading the text of a poem aloud; and (2) when performing the same text as a song. Certain formant frequency differences were observed that were similar to those previously found between professional singers’ spoken and sung vowels. In singing, the intersubject scatter of the three lowest formant frequencies was smaller, and the fourth formant was lower.

Namely how the product variation and product variant were handled (FOOTNOTE 2). However, even if much of our work was introduced for full-scale production purposes was the product planning system practised in the Volvo Uddevalla plant never reformed (even if far-reaching efforts were considered before the closing down). The original planning system was one of the reasons for not being able to reap the potential of this assembly plant (i.e. the time-saving of some 2 – 4 hours in comparison to the Volvo Torslanda plant was not possible to accumulate due to the use of traditional codification of product variants suited for assembly line work) (see some of the other publications registered in Chalmers Public Library CPL).

This publication reports on an alternative system for planning of product variant long before the Volvo Uddevalla plant was closed down.

It illustrated how an engine preheater for a heavy truck chassis is assembled on one of the two assembly lines in the Volvo Tuve plant in Gothenburg. It became obvious for others and us that the original logic of this engine preheater was lost as the components required alternately were fitted at different work stations (implying the fact that the logic of the product architecture and product variation of the physical product are totally destroyed) (in fact, the situation was even worse while taking the computer formalized product information on both of the two Volvo companies into consideration.

Some Considerations About Gas-Fuel Flow Evaluation in a Marine Turbocharged Diesel Engine
- 1982
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The amount of gas flow delivered by the turbocharger is a very important parameter for diesel performance evaluation. Insufficient air flow to the cylinders is frequently the main reason of anomalies in the combustion process, exhaust gas temperature, and consequently in thermal efficiency of diesel engines. Therefore, concerning the actual condition analysis of a diesel engine, there is room to discuss the methods for evaluation of the gas flow through turbochargers.On the other hand the amount of fuel delivered by fuel pump, indicates the amount of heat released inside the cylinders for normal combustion conditions; consequently, it has a great influence on diesel thermodynamic cycles. From this point of view, the diagnostic analysis system and diesel performance evaluation necessitate an accurate estimation of the fuel amount.

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This report is a study of the formal means for specifying properties of network structures as provided by the theory of information management systems. Along with axioms for some simple network structures we show examples of the manner of which intuitive observations on the structures are formulated and proved.
