Hybrid Probabilistic Programs, Alex Dekhtyar, V. S. Subrahmanian

Computer Science and Software Engineering

The precise probability of a compound event (e.g. e1 V e2,e1 Ʌ e2) depends upon the known relationships (e.g. independence, mutual exclusion, ignorance of any relationship, etc.) between the primitive events that constitute the compound event. To date, most research on probabilistic logic programming has assumed that we are ignorant of the relationship between primitive events. Likewise, most research in AI (e.g. Bayesian approaches) has assumed that primitive events are independent. In this paper, we propose a hybrid probabilistic logic programming language in which the user can explicitly associate, with any given probabilistic strategy, a conjunction and disjunction operator, and …

Product Liability, Entry Incentives And Market Structure, Stephen F. Hamilton, David L. Sunding

Economics

The article characterizes the entry incentives provided by increases in product liability under various forms of competition. It is demonstrated that the entry of small, high-cost firms is likely to occur in imperfectly competitive markets when the average damage increases with industry output. Special cases are considered, including Cournot–Nash oligopoly and dominant firm-competitive fringe.

Product Flexibility In Selecting Manufacturing Planning And Control Strategy, Emine Persentili, Sema E. Alptekin

Industrial and Manufacturing Engineering

The manufacturing systems capable of producing several products simultaneously are frequently subject to changes in product types due to demand fluctuations. In such systems a product flexible manufacturing planning and control (MPC) strategy is needed to change from one product type to another with minimum deterioration to system performance levels. The objective of this research is to develop a systematic analysis and evaluation approach in order to compare the MRP-push and JIT-pull strategies quantitatively based on a product flexibility measure. A new product flexibility measure is developed based on the sensitivity to change concept and presented together with the implementation …

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …

On-Line Bayesian Speaker Adaptation By Using Tree-Structured Transformation And Robust Priors, Shaojun Wang, Yunxin Zhao

Kno.e.sis Publications

This paper presents new results by using our previously proposed on-line Bayesian learning approach for affine transformation parameter estimation in speaker adaptation. The on-line Bayesian learning technique allows updating parameter estimates after each utterance and it can accommodate flexible forms of transformation functions as well as prior probability density functions. We show through experimental results the robustness of heavy tailed priors to mismatch in prior density estimation. We also show that by properly choosing the transformation matrices and depths of hierarchical trees, recognition performance improved significantly.

Phased Tilings And Generalized Fibonacci Identities, Arthur T. Benjamin, Jennifer J. Quinn, Francis E. Su

All HMC Faculty Publications and Research

Fibonacci numbers arise in the solution of many combinatorial problems. They count the number of binary sequences with no consecutive zeros, the number of sequences of 1's and 2's which sum to a given number, and the number of independent sets of a path graph. Similar interpretations exist for Lucas numbers. Using these interpretations, it is possible to provide combinatorial proofs that shed light on many interesting Fibonacci and Lucas identities (see [1], [3]). In this paper we extend the combinatorial approach to understand relationships among generalized Fibonacci numbers.

Given G₀ and G₁ a generalized Fibonacci sequence G …

A Quality Future For Recreational Fishing On The West Coast., West Coast Recreational Fishing Working Group

Fisheries Management Papers

The West Coast Region between Kalbarri and Augusta offers a wide range of recreational fishing opportunities.The West Coast Region also receives more fishing pressure than any other, with an estimated 380 000 anglers fishing each year. Already, the signs of a fishery under pressure are showing. Catch rates of dhufish around inshore reef systems such as the Three-mile are a far cry from the 1950s and 60s when people beachlaunched wooden dinghies to fish the inshore waters for these highly prized fish. Increasing pressure on stocks has led to growing community concerns that the future quality of recreational fishing is …

Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.

Fisheries Management Papers

Land supply and land cost for aquaculture may become a limiting factor in the foreseeable future. At present, adequate appropriately zoned land is available at reasonable cost. The most prospective land for aquaculture in or near Esperance is where suitable zoned land occurs over saline ground water aquifers or adjacent to the coast. Careful site selection would be necessary to ensure water supply, waste water disposal, services and operational space can be achieved at reasonable cost.

Fisheries Research Report No. 122 - Western Rock Lobster Mail Surveys Of Licensed Recreational Fishers 1986/87 To 1998/99, Roy Melville-Smith, Sonia M. Anderton

Fisheries Research Reports

Information on the catch, effort and fishing characteristics of recreational rock lobster fishers has been collected in Western Australia (WA) since 1986, by an annual mail survey of a randomly selected sample of rock lobster licence holders. Over the period 1986-1999, the number of licensed recreational rock lobster fishers in WA has approximately doubled, from 15,249 (1987/88) to 32,768 (1998/99), and the estimated catch has nearly tripled, from 219 tonnes (1987/88) to 626 tonnes (1998/99). These estimates have not attempted to take into account illegal catches.

Of those who do fish, approximately 65% of recreational rock lobster licence holders exclusively …

Rate-Distortion Adaptive Vector Quantization For Wavelet Imagecoding, Qun Gu, Scott E. Budge

Electrical and Computer Engineering Faculty Publications

We propose a wavelet image coding scheme using rate-distortion adaptive tree-structured residual vector quantization. Wavelet transform coefficient coding is based on the pyramid hierarchy (zero-tree), but rather than determining the zero-tree relation from the coarsest subband to the finest by hard thresholding, the prediction in our scheme is achieved by rate-distortion optimization with adaptive vector quantization on the wavelet coefficients from the finest subband to the coarsest. The proposed method involves only integer operations and can be implemented with very low computational complexity. The preliminary experiments have shown some encouraging results: a PSNR of 30.93 dB is obtained at 0.174 …

Some Practical Applications Of Soft Computing And Data Mining, Hung T. Nguyen, Nadipuram R. Prasad, Vladik Kreinovich, Habib Gassoumi

Departmental Technical Reports (CS)

Traditional data mining techniques mainly deal with a search for patterns in traditional databases, where data consists of numbers and words. In many application areas, however, data is more complicated: real-life data is often obtained as an image from a camera rather than a few measurements. Furthermore, this image can also change dynamically. In this paper, we present several examples of how soft computing is related to mining such data.

A New Universal Approximation Result For Fuzzy Systems, Which Reflects Cnf-Dnf Duality, Irina Perfilieva, Vladik Kreinovich

Departmental Technical Reports (CS)

There are two main fuzzy system methodologies for translating expert rules into a logical formula: In Mamdani's methodology, we get a DNF formula (disjunction of conjunctions), and in a methodology which uses logical implications, we get, in effect, a CNF formula (conjunction of disjunctions). For both methodologies, universal approximation results have been proven which produce, for each approximated function f(x), two different approximating relations RDNF(x,y) and RCNF(x,y). Since in fuzzy logic, there is a known relation FCNF(x)<=FDNF(x) between CNF and DNF forms of a propositional formula F, it is reasonable to expect that we would be able to prove the existence of approximations for which a similar relation RCNF(x,y)<=RDNF(x,y) holds. Such existence is proved in our paper.

Computers In The Classroom – Do They Really Make A Difference In Student Learning?, Colleen Fitzgerald

Theses and Dissertations

The purpose of this study was to determine if the utilization of computers in the classroom would increase student learning. The participants were eighty-two seventh grade students from Demarest Middle School in Demarest, New Jersey. The students were organized into four heterogeneously mixed classes. The study was conducted over approximately two weeks. All students received introductory instruction on amphibians and frog anatomy and physiology. Two classes then completed the traditional specimen dissection, while the other two classes completed a computer-simulated dissection. The classes then switched and performed the alternative dissection procedure. Their performance was measured by the results on the …

Terdiurnal Oscillations In Oh Meinel Rotational Temperatures For Fall Conditions At Northern Mid-Latitude Sites, W. R. Pendleton Jr., Michael J. Taylor, Larry Gardner

All Physics Faculty Publications

High‐precision (∼0.5 K) measurements of OH Meinel (M) (6,2) rotational temperatures above the Bear Lake Observatory, UT (42°N, 112°W) during October 1996 have revealed an interesting and unexpected mean nocturnal pattern. Ten quality nights (>100 h) of data have been used to form a mean night for autumnal, near‐equinoctial conditions. The mean temperature and RMS variability associated with this mean night were 203 ± 5 K and 2.4 K, respectively, and compare very favorably with expectations based on Na‐lidar measurements of mean tidal temperature perturbations over Urbana, IL (40°N, 88°W) during the fall 1996. Furthermore, this comparison shows that …
