Abstract:
The development of pulp and paper production and technology is reviewed with special emphasis on its influence on the waste water discharge. The chemical pulping methods are in a rapid development phase, including novel processes as well as substantial changes taking place in the kraft pulping process. Due to the changing chemical pulping and bleaching practice, the chlorinated organic compounds in the effluent will lose their importance. Research should be focused on the effects of new contaminants introduced in chlorine-free bleaching, and on the natural substances occurring in wood that are causing the remaining toxicity of the effluent from both mechanical and chemical pulp mills. Enhanced recycling of post-consumer paper and board leads to an increased number of deinking plants with new types of discharges. Closure of process water loops are also expected in the near future, which may totally eliminate the process water discharges from modern mills.

Abstract:
Research is focused on an integrated way to simultaneously optimize the bleaching operations and subsequent wastewater treatment for pulp and paper mills. Bleach wastewaters from ClO2-bleached pulping studies at Institute of Paper Science and Technology (IPST) were used as the feed for batch reactors to test and rank the treatability and kinetics. The key aspect of the system is the use of sequential anaerobic/aerobic phases to enhance reductive dehalogenation of chloro-organic materials. Two continuous reactor systems, one operated in an anaerobic-aerobic mode and a second in an aerobic-aerobic mode, received bleaching wastewater obtained from a full-scale plant. Acclimated cultures from both continuous reactors were used to quantify the AOX (Adsorbable Organic Halide) and COD removal from various bleaching wastewaters. In general, the sequential anaerobic/aerobic treatment of bleach wastewater can improve both biotreatability and degradation rates.

Abstract:
Abstract Objectives Noise exposure is a common occupational hazard, but has not been sufficiently characterized in paper mills. We developed a job-exposure matrix (JEM) for noise exposure for use in estimating exposures among Swedish soft tissue paper mill workers. Methods We used a combination of area and personal dosimetry noise exposure measurements made at four soft tissue paper mills by industry and research staff between 1977 and 2013 to estimate noise exposures by department, location, and job title. We then utilized these estimates, in conjunction with information on process and facility changes and use of hearing protection collected via focus groups, to create a seven-category, semi-quantitative JEM for all departments, locations, and job titles spanning the years 1940–2010. Results The results of the 1157 area and personal dosimetry noise measurements indicated that noise levels have generally declined in Swedish paper mills over time, though these changes have been neither uniform nor monotonic within or across the four mills. Focus group results indicated that use of hearing protection has generally increased over time. The noise JEM totals 1917 cells, with each cell representing a unique combination of operation, job title, and single year. We estimated that ~50% of workers at the four mills assessed were exposed at or above the Swedish 8-h average noise exposure limit of an 85 dBA at the conclusion of the study period in 2010. Conclusions Our results highlight the continuing need for hearing loss prevention and noise control efforts at these and similar mills, and the completed JEM now represents a tool for use in epidemiological studies of noise-related health outcomes.

Abstract:
PurposeThe purpose of this paper is to reveal how the prices, costs, and logistics develop in the case mill and how these variables correlate with profits, and finally to give suggestions for improvements.Design/methodology/approachA typical Finnish paper mill is selected for the basis of the case study. The complete data for the mill for the years 2001 to 2007 at a monthly level are used. The data are obtained from the mill's financial management system and transferred to Excel. Statistica 4.1 software is used to run the statistical correlation analyses. The results can be generalized with certain limitations to paper manufacturing located at a long distance from its customers.FindingsThis paper gives an important insight into the economics of the Finnish paper industry. From theory‐building point of view, the empirical process data show that the variation in production lines is minimal, but there are important variations in paper deliveries. A lot can be gained in the logistics processes. Larger volumes delivered in tons also tend to increase profits. From the mill to the consignees, fluctuations in the process and paper sales grow substantially, which indicates longer storage times.Research limitations/implicationsThe results of the case study are based on the data of a single large integrated paper mill in Finland covering the years 2001‐2007, so the results cannot be directly generalized to concern all Nordic paper mills. In May 2005, there was an industrial blackout, which considerably affected the production and deliveries of all Finnish paper mills in that year.Practical implicationsThe competitive advantages of the Finnish paper industry are undermined by low paper prices and costly logistics. The mill managers should increasingly focus on overcapacity and cost issues and also deliver volumes, which all could contribute to higher profits.Originality/valueIn this paper, the Finnish paper industry is studied through a time series, economic geography, and statistical tools. This approach is a novel method and gives new insights into this research object. The mill's economic variables, such as paper prices, profits, and logistics and manufacturing costs, and the characteristics of these issues in a spatial context are studied.

Abstract:
This study is based on the analysis of the paper and the text of royal and princely accounts in which scribes registered the everyday incomes and expenditures of four Jagiellonian courts, located in different parts of East-Central Europe around the turn of the 15th and 16th-century. The period covers the establishment and the very first years of paper mills in Silesia and the Polish Kingdom. Regarding the lack of archival sources preserving the foundation and running of these mills, the cradles of paper-making in East-Central Europe, one should use many different and quite laconic written sources to shed light upon these revolutionary years. Although accounts could preserve mentions of purchasing, trading and using paper, in most cases the textual information is not adequate to reconstruct a detailed and clear image of paper producing; researchers should examine the medium of writing - the paper - itself. Instead of the investigation of single sheets, folded papers, small notebooks and bound books such as accounts proved to be more useful. One can compare the sheets of the volumes and find those traces which lead to the paper mills, the places of their origin. Through the detailed examination of one especially complex and interesting ledger from the courts of Prince Sigismund, the author attempts to demonstrate the opportunities lay in watermark studies. Furthermore, the article purposes to reflect on the huge hiatus clearly perceptible on the field of watermark research and paper history in East-Central Europe and the necessity of developing a database of watermarks reflecting on the history of paper-making in this region.

Abstract:
This paper presents a fault early warning approach of coal mills based on the Thermodynamic Law and data mining. The Thermodynamic Law is used to describe the working characteristics of coal mills and to determine the multi-parameter vector that characterize the operating state of the coal mill. Data mining technology is applied to analysis the interrelationships among elements of the multi-parameter vector. Then the abnormal boundaries of parameters are calculated based on the distribution of parameters under different working conditions according to the Pauta criterion. Finally, the fault early warning model is implemented combining the abnormal boundaries and the confidence algorithm that can detect the working status of coal mills. Two actual numerical examples are used to illustrate the proposed method is capable of estimating the abnormality of coal mills before the fault happens.

Abstract:
This paper analyzes how a key conflict in Australia's pulp and paper industry became generalized to other sites through environmental action, government regulation, and industry initiative. From 1987–91, Australians debated construction of a new, world-class, export-oriented pulp mill in Tasmania. Rural residents, fishermen, and environmentalists, allied with the Australian Labor Party, succeeded in scuttling the project. Subsequently, the national government launched a major research program, state governments tightened regulations, and industry reduced elemental chlorine use. Any new mills constructed in Australia today would be among the cleanest in the world. This paper is part of a larger, comparative study of technological innovation in the pulp and paper industries of Australia, Indonesia, Malaysia, and Thailand. The author interviewed industry officials, government regulators, research scientists, and environmentalists; visited pulp and paper mills; attended technical conferences; and conducted archival work in these countries during a 12-month period.

Abstract:
碩士<br>元智大學<br>機械工程學系<br>94<br>Due to the raise of living quality, paper consumption are also increased in recent years. The portion of recycled paper is highly increased to meet the goal of environmental protection. The amount of used paper is about 200 tons last year. Paper mills use landfill, incineration or co-fired to handle the used paper problem. Landfill will cause a lot impact to the environment. Incineration will produce dioxin and need to invest a lot of money for the pollution control equipments. To resolve this problem, some research use circulating fluidized bed gasified boiler to burn the paper reject and obtain the combustible gases .to provide PC boilers as the gas fuel. Although the gasified process can eliminate some major problems of the incineration or co-fired, people still can not handle the forming product (such as glass, sand) of the hydro-cyclone machine. In addition, the ashes still need to be processed by landfill. To improve this process, we intend to use high temperature (1500 to 2000 ) plasma gasified process to handle the slagging product. With suitable adjustment of the additives, they can be used as F-class or C-class cement. The research goals are : (1) Adjustment of sludge, paper reject and sand, glasses from hydro-cyclone to proceed the gasification process. Use XRF to analyze the concentration of slagging, and compare with the F-class and C-class cement and conclude the optimized propotions of fuel. (2) Adjustment of various propotions of fuel to proceed the gasification process. Use GC to study the concentration of the syn gas. Also, the calorific value and char content of the syn gas will be analyzed to calculate the conversion factor.

Abstract:
The book takes as its subject a corpus of thirty-three vampire movies made, distributed and exhibited during the peak years of film production in Italy, and certified to be of Italian nationality by state institutions such as the Italian Show Business Bureau and the Italian Film Censorship Office. Positioning itself at the intersection of Italian film history, horror studies and cultural studies, the book asks: why, and how, is the protean, transnational and transmedial figure of the vampire appropriated by Italian cinema practitioners between 1956 and 1975? Or, more concisely, what do the vampires of post-war Italian cinema mean? The aim is to show that – in spite of Italian vampire cinema’s imported and derivative nature, and its great reliance on profits coming from distribution on the international market – Italian cinematic vampires reflect their national zeitgeist from the economic miracle of the late 1950s to the mid-1970s austerity, twenty years of large political and socio-economic change in which gender politics were also in relative flux. The result of an original research into film production data, film censorship files, screenplays, trade papers, film magazines and vampire-themed paraliterature, the book leaves the well-trod track of award-winning art films to shed light on some of the so-called ‘lower forms’ of cinematic culture, looking for the economic backbone and cultural instrumentality of post-war Italian cinema in the run-of-the-mill genre movies rushed through a cheap production and into domestic and international distribution to parasitically (vampirically?) exploit a given commercially successful film.

Abstract:
The pressure to excel, peer perceptions, and the lack of faculty enforcement are among several factors that lead students to cheat in general. When circumstances of Academic Integrity (AI) among international students were examined, findings revealed prevalence of academic misconduct behaviors due to several factors. When admitting several academic dishonesty behaviors as accepted practices, a sweeping majority of international students denounced cheating as opposed to their own cultural, ethical, and religious beliefs. Several forms of academic misconduct behaviors are more frequent among international students than others. These included unauthorized help, cheating on online tests and utilizing Internet paper mills. Suggested strategies for minimizing misconduct practices of international students included: orientation training, a focus on learning outcomes, alleviating the social pressure, raising students' awareness about academic expectations, and building on the students' ethical backgrounds.

Abstract:
Research on the restructuring of work has tended to neglect the autonomous effects that symbolic or cultural influences can have on the utilization of new technologies. This article draws on fieldwork conducted in three pulp and paper mills to explore the symbolic boundaries that occupational groups bring to bear on the process of workplace automation. As sophisticated technologies and management methods were introduced, process engineers engaged in subtle yet important efforts to portray manual workers’ knowledge in derisive terms. Such boundary work led managers to institute credential barriers that restricted manual workers’ opportunities, eventually enabling engineers to gain exclusive control over analytic functions as their own “natural” domain. The study suggests that symbolic representations can have powerful consequences for the restructuring of work, reproducing social inequalities even when new technologies render them unnecessary.

Abstract:
In the absence of large-scale pectin production in Ukraine, pectin-containing powders are an alternative source. They are used as natural additives in the manufacture of health products, due primarily to the presence of pectin, as well as other useful natural components of raw materials. The purpose of the work is to conduct research on the dispersion and fractionation of dried plant materials and to determine the energy-saving regimes of these processes. The task of the research is to develop optimal modes of dispersion of dried plant materials; determine the depend-ence of the micromill performance and power consumption on the rotation speed of the dispersant rotor; to establish the influence of the load on the sieve and the scattering time on the fractionation process. Objects, equipment and research methods. Dried pectin-containing apples and table beets were used as research objects. Studies of the dispersion process were performed on an micromill (8-MM), the coarse part was ground on a disintegrator (ДЕЗІ), the study of the dispersed composition of powders was carried out on the device 029. The paper analyzes the existing methods of grinding and equipment for its implementation. The analysis showed that percussion mills are the most suitable for grinding dried pectin-containing apples and table beets. The dispersed composition of pectin-containing powders is determined in the article. The influence of material loading on the sieve and scattering time on the yield of the fine fraction was investigated. It is proved that the scattering process is more influenced by the scattering time. The paper graphically shows the effect of rotor speed on the equivalent particle diameter and powder dispersion; differential and integral particle distribution curves depending on rotor speed and scattering time for apple and beet powders; the dependence of micromill productivity and power consumption on the speed of the disperser rotor, etc. The optimal operating speed of the rotor is 50 m/s. At this speed, energy consumption for grinding dried materials is minimal. It is proved that the fractionation process almost does not depend on the load on the sieve, but depends on the scattering time. It is impractical to increase the process duration over 3 minutes. Increasing the time to 4 minutes increases the mass of the fine fraction by only 2…5%. The yield of the fine fraction of powders according to the optimal modes of dispersion and separation is: apple – 65...68%, beet – 62...65%. The possibility of re-grinding in order to increase the fine fraction yield is shown. Conclusions. According to the results of the research, the optimal dispersion regimes, the dependence of micromill productivity and power consumption on the dispersant rotor speed, as well as the effect of load on the sieve and scattering time of apple and beet powders on the fractionation process are determined. On the basis of the conducted researches energy-saving conditions of processes of dispersion and fractionation of pectin-containing powders and proper work of the corresponding equipment are defined.

Portal features differ, but typically contain a single authentication process and access to metadata as well as some services (Laouar, Hacken, &amp; Miles, 2009). The authors examined 87 papers in their review. This examination revealed six themes including: developing library portals, utilizing assessment strategies, collaborating on portal projects, incorporating personalization and customization features, conducting environmental scans, and creating instructional portals. The authors assigned themes to the papers based on the primary focus of the material. The findings revealed various issues with the development of academic library portals. The content of academic library portals continues to evolve as their importance to the user increases. Ultimately, an examination of the literature illustrated academic libraries' efforts to remain relevant through the availability of new resources and services on their portals.

Abstract:
The howler monkey is one of the loudest animals in the world. Its haunting calls can be heard several miles away in dense forest. Today, with the help of the computer, even the quietest human voice can be heard anywhere on the planet. Computers are social machines. They constantly talk to each other in a network that crosses oceans, mountains, and continents. They speak a common universal language, independent of country. Their pulsing, error-correcting messages comprise the industry, knowledge, culture, thoughts, and dreams of the human species. The virtual Web of knowledge now connects humans together in ways never before possible. But with this freedom comes problems. Should we trust everyone who communicates with us? Do we need new ways to protect our privacy? . . . Claude Shannon took his hand from the chess piece and looked up. His sharp eyes fixed on his young opponent. ‘Check!’ Shannon was visiting from Bell Labs in 1955. It was only natural that he should spend an occasional evening at the Palo Alto Chess Club, for he had a keen interest in chess. Five or six years previously he had published several papers about how computers could be programmed to play chess and he was increasingly becoming interested in how machines could be made to perform intelligent tasks. His opponent, Peter Kirstein, a twenty-two-year-old PhD student of Stanford University, was enjoying the game. He had been playing chess since school and was no pushover. Kirstein didn’t really know Shannon, but found the thirty-nine-year-old scientist to be an impressive person, very thin, with piercing eyes. Although the two players didn’t realize it, this was a chance meeting of an established pioneer and a future pioneer who would build on Shannon’s work in ways neither could have dreamed. In 1955, the work that would become so important to Kirstein in the future was already in Shannon’s past. It had originated because of crackling telephone lines. The research and development group in Bell Labs had been struggling with the issue of long-distance communications. At the time, telephone communication was analogue.

Abstract:
Abstract During the completion phase of an unconventional well in Turkey, casing deformation represented a challenge to the operator and Coiled Tubing (CT) service provider due to the potential loss of almost 70% of the horizontal section. The deformation obstructed the path to continue the milling the remaining plugs. The implementation of bicentric mills and Multi-Cycling Circulation Valve (MCCV) incorporated in the milling assembly allowed efficient recovery of the horizontal section. The tubing condition analysis done by the engineering team showed that symmetric mills would not be beneficial. Conformance tubing was not an option. Bicentric milling approach was deemed the most viable solution. This approach consists of using offset mills where rotation causes the cutting head to cover an area larger than the mill's frontal face. However, this approach could lead the CT pipe getting stuck due to big junk left. The use of a MCCV, limiting the number of milled plugs, and performing a fishing run between milling runs were key to the success of the bicentric milling approach. The Turkish well was completed with ten stages isolated by nine aluminum plugs. During the fracturing of stage seven, an abnormal pressure drop was observed while keeping the same pump rate, indicating possible casing damage. After all the stages were fractured, the CT proceeded to mill the plugs using a 4.63-in Outside Diameter (OD) mill. After three plugs were milled, an obstruction was detected, indicated by frequent aggressive motor stalls at the same depth. A tapered mill was run to perform a tubing conformance, and after several hours of unsuccessful penetration, the tool was recovered. At the surface, the tool showed signs of wear around 4.268 in. A 4.0-in OD mill was used to drift this section, and it passed free. An analysis of both the plug anatomy and the casing condition was done to determine the most viable solution. A 4-in OD bicentric mill was designed to pass across the restriction with an adjusted eccentricity to allow higher contact area. Three bicentric milling runs were made with the limit of a maximum of two plugs per run to avoid a CT stuck situation due to the larger cuttings as a result of the mill's asymmetry. The sparsity of information on using bicentric mills for plug milling required research into unpublished practices for such scenarios. This paper documents bicentric milling approach, the use of offset mills, and the mitigation measurements taken during this project to avoid a stuck situation due to large debris generated.

Abstract:
This paper analyzes the influence of the misalignment between the master gear shaft and the top shaft in the durability of the latter. Previous research papers describe that the harmful influence of an excessive flotation, fundamentally in the life of the top shaft, is due to an increase of contact forces in the square coupling. No previous papers include an analysis of the loads that would allow you to know the value of the installation misalignment for a flotation in a certain operation, in order to reach a tensional state more favorable in the more frequent areas of failure of these shafts. The described procedure permits you to know the optimum values of the installation misalignment for a certain mill and the acting load system with which the durability of the shafts of the sugar cane mills is increased. The tool used to reach these results, is the Fracture Mechanic applied along with a satisfactory analysis diagram from the point of view of the load system treatment, and the exactness reached in the calculations.

Abstract:
The application of Titanium alloys are increasingly seen at aerospace, marine, bio-medical and precision engineering due to its high strength to weight ratio and high temperature properties. However while machining the titanium alloys using solid carbide tools, even with jet infusion of coolant lower tool life was vividly seen. The high temperatures generated at the tool-work interface causes adhesion of work-material on the cutting edges and hence shorter tool life was reported. To reduce the high tool work interface temperature positive rake angle, higher primary relief and higher secondary relief were configured on the ball nose end-mill cutting edges. However after a initial working period the growth of flank wear facilitates higher cutting forces followed by work-material adhesion on the cutting edges. Therefore it is important to blend the: strength, sharpness, geometry and surface integrity on the cutting edges so that the ball nose end mill would demonstrate an extended tool-life. This paper illustrates the effect of ball nose end mill geometry on high speed machining of Ti6Al4V. Three different ball nose end mill geometries were configured and high speed machining experiments were conducted to study the influence of tool geometry on the metal cutting mechanism of Ti-6Al-4V alloy. The high speed machining results predominantly emphasize the significance of cutting edge features such as: K-Land, rake angle and cutting edge radius. The ball nose end-mills featured with a short negative rake angle of value −5° for 0.05–0.06 mm i.e., K-Land followed by positive rake angle of value 8° has produced lower cutting forces signatures for Ti-6Al-4V alloy.

Abstract:
Milling operations are commonly characterized by high energy consumptions and should be in focus for optimizations aiming sustainable manufacturing processes. Research results show that within milling operations, especially in small and medium enterprises (SME), up to 80% of the applied milling cutters are solid end mills. The paper presents a design of experiments (DOE)-based optimization of the cutting edge geometry, to improve the energy efficiency and technical capability of solid end mills. Thereby the paper describes the fractional factorial design for the first-degree polynomial model as well as the subsequent set up of a central composite design (CCD) with its second-degree polynomial model for the optimization of relevant target parameter like cutting performance, tool wear and surface quality. Based on the results of more than one hundred machining tests this comprehensive approach shall contribute to the development of new cutting edge geometries of solid end mills and thereby lead to more energy-efficient machining operations in milling applications.

Full text
Abstract:
Many different modes of chatter and their possible causes have been identified after years of research, yet no clear and definite theory of their mechanics has been established. One of the most important reasons for this can be attributed to the fact that only oversimplified models with a single input and a single output were historically used to formulate chatter in rolling. Such a situation has hindered a complete analysis of the underlying mechanisms. In this paper, a state-space representation of single- and multi-stand chatter models will be proposed in a rigorous and comprehensive mathematical form for stability analysis of the various chatter mechanisms. First, a dynamic model of the rolling process that utilizes homogeneous deformation theory will be established that includes the material strain-hardening and work roll flattening effects. By coupling this dynamic rolling process model with a structural model for mill stands, a single-stand chatter model in a state-space representation will be proposed. Based on the single-stand chatter model, a multi-stand chatter model will be formulated by incorporating the inter-stand tension variations and the time delay effect of the strip transportation. A simulation program will also be presented for the study of the dynamic rolling process in the time domain and for verifying the results from stability analysis.

Abstract:
The WEPP in China, is the longest high-pressure pipeline in the world, eastern part of whose construction has been finished at the 1st Oct. 2003. Up to now, all the pipes of trunk line have been welded and buried under ground, about 740,000 metric tons of which were made by domestic pipe mills. Before this project the capacity of domestic pipe mills is pretty low: the max. O.D. is 711mm, the max. W.T. is 10.7mm, and the highest steel grade is API X60. However, the WEPP specification is very high: X70 with about 50% acicular ferrite, O.D. 1016mm, W.T. 14.6/17.5/21.0/26.2mm, and more than 190 J CVN value under −15 . This kind of pipe has never been made before in China. However, within about 2 years, Chinese mills successfully fulfilled the development and manufacturing of X70 steel coils and plates, the technical reconstruction of old production lines and installation of the new ones, the scientific research of pipe forming and high speed welding technology and test method, and the technology development of procedure and facilities for inside flow coating and outside 3PE coating. All the above will be detailed in this paper.

Full text
Abstract:
Helical milling is a 3-axis machining operation where a cutting tool is feed along a helix. This operation is used in ramp-in and ramp-out moves when the cutting tool first engages the workpiece, for contouring and for hole machining. It is increasingly finding application as a means for roughing large amounts of material during high speed machining. Modeling the helical milling process requires cutter/workpiece engagements (CWEs) geometry in order to predict cutting forces. The calculation of these engagements is challenging due to the complicated and changing intersection geometry that occurs between the cutter and the in-process workpiece. In this paper we present a geometric modeling methodology for finding engagements during helical milling with flat end mills. A mapping technique has been developed that transforms a polyhedral model of the removal volume from Euclidean space to a parametric space defined by location along the tool path, engagement angle and the depth-of-cut. As a result, intersection operations are reduced to first order plane-plane intersections. This approach reduces the complexity of the cutter/workpiece intersections and also eliminates robustness problems found in standard polyhedral modeling and improves accuracy over the Z-buffer technique. The reported method has been implemented and tested using a combination of commercial applications. This paper highlights ongoing collaborative research into developing a Virtual Machining System.

Abstract:
Accurate process modeling requires the calculation of cutter/workpiece engagement (CWE) geometry. This is challenging when the geometry of the workpiece is changing un-predictably as is the case for most machined components of moderate complexity. Solid modelers are increasingly being considered as a computational engine for performing these calculations. This is largely due to increased robustness and computing efficiency that is evolving within this technology. The vast majority of reported research using solid modelers focuses on the domain of 2 1/2 D machining with flat end mills. While significant there remain restrictions in the types of inprocess workpiece geometry that can be processed with these approaches. In particular, they assume a constant axial engagement for a connected set of tool paths. This assumption cannot be made when the initial workpiece geometry is non-rectangular prismatic stock, when multiple setups are machined and when tool changes introduce tools of different diameters. In these cases the depth of engagement can vary over a single rotation of the cutter even though there is no axial feed motion. In this paper a solid modeling based solution is presented for calculating these engagements when multiple setups and tool changes are considered. Orthogonal setups and flat end mills are assumed so as to preclude cutter engagement on inclined workpiece faces. Classes of Cutter Engagement Features (ceFs) are defined to support this approach. Algorithms for ceF extraction are provided and validated using a test part. This research introduces the use of features and extends the capabilities of solid modeling techniques for cutting force prediction.

Abstract:
The Indiana Department of Transportation (INDOT) operates a fleet of nearly 1100 snowplows and spends up to $60M annually on snow removal and de-icing as part of their winter operation maintenance activities. Systematically allocating resources and optimizing material application rates can potentially save revenue that can be reallocated for other roadway maintenance operations. Modern snowplows are beginning to be equipped with a variety of Mobile Road Weather Information Sensors (MARWIS) which can provide a host of analytical data characterizing on-the-ground conditions during periods of wintry precipitation. Traffic speeds fused with road conditions and precipitation data from weather stations provide a uniquely detailed look at the progression of a winter event and the performance of the fleet. This research uses a combination of traffic speeds, MARWIS and North American Land Data Assimilation System (NLDAS) data to develop real-time dashboards characterizing the impact of precipitation and pavement surface temperature on mobility. Twenty heavy snow events were identified for the state of Indiana from November 2018 through April 2019. Two particular instances, that impacted 182 miles and 231 miles of interstate at their peaks occurred in January and March, respectively, and were used as a case study for this paper. The dashboards proposed in this paper may prove to be particularly useful for agencies in tracking fleet activity through a winter storm, helping in resource allocation and scheduling and forecasting resource needs.

Abstract:
Grand Canyon National Park is all about time and timescales. Time is the currency of our daily life, of history, and of biological evolution. Grand Canyon’s beauty has inspired explorers, artists, and poets. Behind it all, Grand Canyon’s geology and sense of timelessness are among its most prominent and important resources. Grand Canyon has an exceptionally complete and well-exposed rock record of Earth’s history. It is an ideal place to gain a sense of geologic (or deep) time. A visit to the South or North rims, a hike into the canyon of any length, or a trip through the 277-mile (446-km) length of Grand Canyon are awe-inspiring experiences for many reasons, and they often motivate us to look deeper to understand how our human timescales of hundreds and thousands of years overlap with Earth’s many timescales reaching back millions and billions of years. This report summarizes how geologists tell time at Grand Canyon, and the resultant “best” numeric ages for the canyon’s strata based on recent scientific research. By best, we mean the most accurate and precise ages available, given the dating techniques used, geologic constraints, the availability of datable material, and the fossil record of Grand Canyon rock units. This paper updates a previously-published compilation of best numeric ages (Mathis and Bowman 2005a; 2005b; 2007) to incorporate recent revisions in the canyon’s stratigraphic nomenclature and additional numeric age determinations published in the scientific literature. From bottom to top, Grand Canyon’s rocks can be ordered into three “sets” (or primary packages), each with an overarching story. The Vishnu Basement Rocks were once tens of miles deep as North America’s crust formed via collisions of volcanic island chains with the pre-existing continent between 1,840 and 1,375 million years ago. The Grand Canyon Supergroup contains evidence for early single-celled life and represents basins that record the assembly and breakup of an early supercontinent between 729 and 1,255 million years ago. The Layered Paleozoic Rocks encode stories, layer by layer, of dramatic geologic changes and the evolution of animal life during the Paleozoic Era (period of ancient life) between 270 and 530 million years ago. In addition to characterizing the ages and geology of the three sets of rocks, we provide numeric ages for all the groups and formations within each set. Nine tables list the best ages along with information on each unit’s tectonic or depositional environment, and specific information explaining why revisions were made to previously published numeric ages. Photographs, line drawings, and diagrams of the different rock formations are included, as well as an extensive glossary of geologic terms to help define important scientific concepts. The three sets of rocks are separated by rock contacts called unconformities formed during long periods of erosion. This report unravels the Great Unconformity, named by John Wesley Powell 150 years ago, and shows that it is made up of several distinct erosion surfaces. The Great Nonconformity is between the Vishnu Basement Rocks and the Grand Canyon Supergroup. The Great Angular Unconformity is between the Grand Canyon Supergroup and the Layered Paleozoic Rocks. Powell’s term, the Great Unconformity, is used for contacts where the Vishnu Basement Rocks are directly overlain by the Layered Paleozoic Rocks. The time missing at these and other unconformities within the sets is also summarized in this paper—a topic that can be as interesting as the time recorded. Our goal is to provide a single up-to-date reference that summarizes the main facets of when the rocks exposed in the canyon’s walls were formed and their geologic history. This authoritative and readable summary of the age of Grand Canyon rocks will hopefully be helpful to National Park Service staff including resource managers and park interpreters at many levels of geologic understandings...
