Thinning and turbulence in aqueous films
This thesis covers the topic ”Thinning and Turbulence in Aqueous Films”. Experimental studies in two-dimensional systems gained an increasing amount of attention during the last decade. Thin liquid films serve as paradigms of atmospheric convection, thermal convection in the Earth’s mantle or …

Thinning of point processes-covariance analyses
… of problems in point process theory called 'thinning'. By thinning we mean an operation whereby a point process is split into two point processes by some rule. We obtain the covariance structure between the thinned processes under various thinning rules. We first obtain this structure for …

Artificial Intelligence-Based Decision Automation for Apple Orchard Thinning
… worth of high-quality pip fruit by 2030. Apple thinning is essential to quality but is also seasonal, leading to a high demand for skilled labour. However, labour shortages have been experienced globally due to the labour-intensive nature of hand-thinning and low wages. Apple thinning involves …

Cortical thinning and neuropsychological changes in presymptomatic Huntington's Disease
… results. They found significant cortical thinning in participants with early HD (Rosas et al., 2002; Rosas et al., 2008) and even in presymptomatic HD (Rosas et al., 2005). Moreover, cortical thinning was most prominent in posterior regions of the brain, with relative preservation of the …

Response of Pinyon-juniper woodlands to fire, chaining, and hand thinning
… Nevada to look at the effects of fire, hand thinning, and chaining. The four burns examined together in Chapter 1 had similar elevation, precipitation, and pre-treatment vegetation communities in the untreated areas, but the treated areas had significantly different responses to treatment. …

Development of a table-top robot model for thinning of fruit
… of human labor, a concept of automatic selective thinning was pursued to improve the production of peach, apple and other fruits. In this research, a table-top robot model was developed to prove the concept, with an emphasis on a task planning algorithm. The algorithm moved a custom six-DOF …

Economic analysis of thinning alternatives in natural stands of yellow-poplar
… information required by landowners to evaluate thinning alternatives in yellow-poplar stands. The program is written Applesoft BASIC for the APPLE II+ microcomputer with a design which emphasizes flexibility and ease of use. The program consists of two primary segments: growth and yield, and …

Comparison of chemical and manual methods of precommerical thinning oak stump-sprouts
Precommercial thinning of 12-year-old upland oak stump-sprouts in southwestern Virginia using herbicides and manual felling was compared. Objectives were to quantify and compare residual crop-stem growth and treatment costs between treatments and application methods. 2,4-D and triclopyr were …

Evaluating the accuracy of line thinning algorithms after processing scanned line data
… of this study is to analyze the accuracy of thinning methods applied to scanned map data, which is only one in a series of processes used to accomplish digital conversion of conventional maps. In preliminary tests, nine thinning methods based on the successive layer removal process are …

Formation of microfibers and nanofibers by capillary-driven thinning of drying viscoelastic filaments
… and nanofibers by exploiting elasto-capillary thinning and stretching of macroscopic liquid bridges (Harfenist et al., Nano Lett., 4(10),2004). We develop a model of this process that describes the simultaneous visco-elasto-capillary thinning, stretching and drying of cylindrical filaments of …

The potential use of 35mm aerial photography in planning a selective mechanized thinning
… 35mm aerial photos to space access corridors for thinning two overstocked loblolly pine plantations in the piedmont of Virginia. Tree diameters at groundline were predicted as functions of photo-measured crown areas. The capacity of the accumulator on the feller-buncher, an assumed operating …

Precision Forestry: Using LiDAR to Optimize Row Thinning in Pinus taeda (L.) Plantations
… sub-stand management treatments, such as stand thinning guidelines. This study uses LiDAR to assess individual-tree stem volumes in Pinus taeda L. plantations in the southeast US. Currently, starting rows in commercial row thinning operations are arbitrarily selected, but the study used LiDAR …

Effects of non-commercial thinning on Great Horned Owls on Turnbull National Wildlife Refuge
… including prescribed burning and non-commercial thinning. The impacts of thinning on owl species diversity and habitat occupancy have not been studied in these ponderosa pine forests. My study had the following objectives 1) compare forest stand metrics between treatment plots, 2) compare owl …

Comparison of a large and small grapple skidder in a pine plantation thinning application
… (185 horsepower) grapple skidder in corridor thinning applications in southern pine plantations. Comparisons included (1) time and production, (2) residual stand damage, (3) soil compaction, (4) cost, and (5) the impact of tree size on productivity. The large grapple skidder was found to be …

Novel Shear-Thinning of Aged PDMS/Fumed Silica Admixtures and Properties of Related Silicone Elastomers
Fumed silica filler has long been used to structurally reinforce silicone elastomers. Unfortunately, the combination of as little as a few weight percent of untreated fumed silica nanoparticles [uFSN] with a siloxane polymer, such as PDMS, forms a difficult to process waxy solid admixture that even …

Economic comparisons of thinning from above and below in Loblolly Pine plantations using dynamic programming
Thinning from above and below were compared using an economic optimizing dynamic program, FORTE (Arthaud 1986). Economically optimal (net present value maximizing) thinning regime and rotation age were determined for benchmark economic and model inputs. Sensitivity of net present value and optimal …

Investigation of Regulatory Mechanisms of Chemical-Mediated Fruit Thinning in Apple (Malus X Domestica Borkh.)
Fruit thinning is critical to the success of apple industry because most apple trees are prone to biennial bearing characterized by heavy bloom and over-cropping in the "on" year and low or no cropping in the "off" year. Fruit thinning can improve fruit size, increase return bloom, and reduce …
