Foundations Of Fuzzy Sets, Lawrence Stout, Ulrich Höhle Dec 1990

Foundations Of Fuzzy Sets, Lawrence Stout, Ulrich Höhle

Lawrence N. Stout

This paper gives an overview of the origins of fuzzy set theory and the problems for the foundations of fuzzy sets arising from those origins and current practice. It then gives detailed accounts of categorical approaches using a closed structure to capture the fuzzy AND connective. Within these categories weak forms of subobject representations provide an internal second order logic. An approach to fuzzy real numbers and fuzzy topology is included to illustrate the use of this internal; second order theory.

Reductions Of Graphs And Spanning Eulerian Subgraphs, Zhi-Hong Chen Dec 1990

Reductions Of Graphs And Spanning Eulerian Subgraphs, Zhi-Hong Chen

Zhi-Hong Chen

This dissertation is primarily focused on conditions for the existence of spanning closed trails in graphs. However, results in my dissertation and the method we used, which was invented by Catlin, are not only useful for finding spanning closed trails in graphs, but also useful to study double cycle cover problems, hamiltonian line graphs problems, and dominating closed trail problems, etc. A graph is called supereulerian if it contains a spanning closed trail. Several, people have worked on the conditions for spanning closed trails having the form "d(u) + d(v) $>$ cn (0 $<$ c $<$ 1)" for all edge …


A Survey Of Fuzzy Set And Topos Theory, Lawrence Stout Dec 1990

A Survey Of Fuzzy Set And Topos Theory, Lawrence Stout

Lawrence N. Stout

This paper is a comparison and contrast of approaches to many-valued mathematics offered by Fuzzy Set theory and topos theory. It gives a survey of the categorical foundations of Fuzzy Set theory and related topoi. Topoi are not a basis for Fuzzy Set theory but they do suggest appropriate directions to go and questions to ask for a synthesis which does provide a foundation. One possible structure which has a topos-like internal logic and the, rich variety of logical connectives used in fuzzy sets is included.

Acquisition Of An Electron Probe Microanalyzer, Andrea Koziol, Robert Wintsch, Michael Dorais, Edward Ripley, Enrique Merino

Andrea M. Koziol

This award will provide half of the funds needed for the acquisition of an electron microprobe. This new electron microscope will primarily serve the needs of the Geology faculty and graduate students in the Department of Geological Sciences at The University of Indiana. The University of Indiana is committed to provide the additional funds to make this acquisition possible. Seven Geology Department faculty and their students have been identified as primary users. Six other faculty expect to be less frequent or occasional users. This large group of faculty and their students pursue research in diverse areas (e.g. thermodynamic links between …


Solving Ill-Posed Problems With Artificial Neural Networks, Arun D. Kulkarni Dec 1990

Solving Ill-Posed Problems With Artificial Neural Networks, Arun D. Kulkarni

Arun Kulkarni

With many physical problems, measurement of spectral distribution, cosmic radiation, aerial and satellite imaging indirect sensing/recording devices are used. In many of these cases, the recording systems can be modeled by a Fredholm integral equation of the first kind. An inversion of the kernel representing a system, in the presence of noise, is an ill-posed problem. The direct inversion often yields an unacceptable solution. In this paper, we suggest an artificial neural network (ANN) architecture to solve certain kinds of ill-posed problems. The weights in the model are initialized using eigen-vectors and eigen-values of the kernel matrix that characterize the …

Universal Conductivity Curve For A Plane Containing Random Holes., E. J. Garboczi, M. F. Thorpe, M. S. Devries, Anthony Roy Day

Anthony Roy Day

This paper examines the general percolation problem of cutting randomly centered insulating holes in a two-dimensional conducting sheet, and explores how the electrical conductivity sigma decreases with the remaining area fraction. This problem has been studied in the past for circular, square, and needlelike holes, using both computer simulations and analog experiments. In this paper, we extend these studies by examining cases where the insulating hole is of arbitrary shape, using digital-image-based numerical techniques in conjunction with the Y- [nabla] algorithm. We find that, within computational uncertainty, the scaled percolation threshold, xc=nc=5.9±0.4, is a universal quantity for all the cases …


Review Essay Of Two Books On The History Of Science, Charles Kay Smith Dec 1990

Review Essay Of Two Books On The History Of Science, Charles Kay Smith

Charles Kay Smith

Contrary to what I was taught in high school in the mid-1940s, science is no longer defined as an inductive methodology for immaculately conceiving culture-free truth after sifting through a huge data base of objective facts. For without some prior hypothesis to guide her, a scientist would not be able to decide which facts were relevant. Nowadays hypotheses can come from anywhere in the imagination or culture within which the scientist is working. The importance of a scientific hypothesis is that it be framed in such a way that it can be falsified when tested. Science now has a history …

What's The Sleepgram Pillows Made Of ?, Jmes Modmd

jmes modmd

The spread texture of this pad is produced using 100% cotton, and Sleepgram pillow feels excessively delicate and light. A zipper traverses the side of the cushion enabling sleepers to effectively evacuate the spread when it's a great opportunity to be washed. Inside the spread are two separate pads shrouded in 100% polyester and loaded up with a cushy down-elective called poly microfiber. These internal pads are named with a blue marker, and a red marker, signifying delicate and medium firmnesses individcually. This enables the sleeper to blend and match cushion arrangements so as to alter firmness.Leave just the blue …


Higgs-Boson Production In Peripheral Heavy-Ion Collisions: Electromagnetic Production, Alec Schramm, Burndt Muller Nov 1990

Higgs-Boson Production In Peripheral Heavy-Ion Collisions: Electromagnetic Production, Alec Schramm, Burndt Muller

Alec J Schramm

Higgs-boson production via fusion of two virtual photons in nuclear collisions at energies of several TeV per nucleon is calculated. It is shown that although a trigger on quasielastic nuclear collisions suppresses the Higgs-boson production cross section, this mechanism could still provide a method for producing and detecting intermediate-mass Higgs bosons (MZ≲MH≲2MW).

Do A Man Enhancement Supplementations Really Their Job?
Some sites even say it's more important when (what time of day) you eat or not eat than what you eat. When it comes to factors that increase the risk of developing diabetes, a diet low in cereal fiber and rich in high-glycemic-index foods (which cause big spikes in blood sugar) seems particularly bad. Controlling for a slew of these and other risk factor for heart disease - like alcohol consumption, smoking history, body mass index, regular doctor visits, quality of diet, TV watching, activity level, and sleep habits - did reduce …

On The Electrochemical Etching Of Tips For Scanning Tunneling Microscopy, Nancy Burnham, J. Ibe, P. Bey Jr., S. Brandow, R. Brizzolara, D. Dilella, K. Lee, C. K. Marrian, R. Colton Jun 1990

On The Electrochemical Etching Of Tips For Scanning Tunneling Microscopy, Nancy Burnham, J. Ibe, P. Bey Jr., S. Brandow, R. Brizzolara, D. Dilella, K. Lee, C. K. Marrian, R. Colton

Nancy A. Burnham

The sharpness of tips used in scanning tunneling microscopy(STM) is one factor which affects the resolution of the STM image. In this paper, we report on a direct‐current (dc) drop‐off electrochemicaletching procedure used to sharpen tips for STM. The shape of the tip is dependent on the meniscus which surrounds the wire at the air–electrolyte interface. The sharpness of the tip is related to the tensile strength of the wire and how quickly the electrochemical reaction can be stopped once the wire breaks. We have found that the cutoff time of the etch circuit has a significant effect on the …

With this combination you will have success and it will be a long term success unlike so many crash diets. My mind went boinnnng! when I made this discovery, and it's been a source of life-changing results. Avoid Sugar before bed. (You were avoiding sugar anyway right?) Consuming sugar right before bed leads to a blood sugar roller coaster ride, potentially waking you up in the middle of the night due to a blood sugar low.
