The Application of Personal Digital Assistants as Mobile Computing Device on Construction Site

Construction managers need to access the real construction site to manage the construction project. They have recently handled various types of digital information such as drawings, specification, checklists and daily reports. They usually use sheets of paper and/or field notes. As a result, a gap in time and space between the outdoor construction site and the office, which leads to the low efficiency, occurs. This paper reports the application of PDA (Personal Digital Assistants) as mobile computing device for construction managers on construction sites. First, this paper describes the aim and the essential element of the mobile systems. This also shows the analysis of necessary functions as mobile computing device through the discussion with construction managers, and the concept of development of this computer-aided engineering system. Secondly, this paper describes the outline of below subsystems with PDA: Progress Monitoring System, Inspection System and Position Check System. Subsystems have two programs: the data input program in PDA and the output program in PC. Finally, this paper indicates the development of more refined process of construction management with the mobile computing device on construction site. • Progress Monitoring System has been built for construction managers to monitor the progress of works. This is especially useful for apartment building projects because of the large number of rooms. Construction managers can share the current progress of all rooms soon. • Inspection System has been built for construction managers to inspect the result of construction. PDA displays the code and/or checklists each building element and work. They plot the position of unacceptable on a drawing and select related items from the lists in PDA. The output program of the system in PC can print the instruction document for subcontractors to correct improper workmanship. • Position Check System has been built for construction managers to check the position of steel members in the structural steel erection. The output program of the system in PC can show the actual form of steel frame considering the fabric distortion graphically and the scatter of accuracy of steel erection with graph.
A short-term demand forecasting model from real-time traffic data

Developing real-time traffic diversion strategies is a major issue of Advance Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems(IVHS). Traffic diversions attempt to maximize the use of available capacities in the roadway systems during congestion-causing events. In selecting the diversion route, the decision is based that the route may not become congested by the time the diverted drivers reach that part of the network. Thus the forecasting of expected traffic flow on various parts of the network in a prompt and accurate fashion would help determine the efficient alternate routes. In this research, a prediction model has been developed to provide traffic forecasts. It has two components. One component is an Auto Regressive Integrated Moving Average (ARIMA) model based on the previous traffic data. The other component is the average traffic flow for that period as obtained from previous days. These two components are combined to represent the fluctuations in the traffic flow behaviour.
Variance Estimation

A basic requirement of any estimate is a measure of its precision or uncertainty. This is typically provided by estimates of variance and associated confidence intervals. Derivation of computationally and statistically efficient estimates of the variance of the coverage adjustment estimates is therefore crucial for the evaluation of these estimates. Variance estimates provide information on their level of accuracy and 95% confidence intervals will allow them to be appropriately compared to external population estimates.
LONGITUDINAL BARRIERS FOR BUSES AND TRUCKS

In May 1976 two significant accidents occurred involving traffic bridge rails. An ammonia truck in Houston, Texas, struck a bridge rail leaving 11 dead, 73 hospitalized, and causing 100 other injuries for a total of 184 casualties. In Martinez, California, a school bus struck a bridge rail and left 29 dead and 23 injured. As a result of these accidents, an extensive effort has been made to develop longitudinal traffic barriers or rails capable of restraining and redirecting buses and large trucks. The results of 34 crash tests conducted using automobiles and mostly buses and trucks on 16 different traffic rails were obtained from the references. Vehicles represented are 4,500-lb passenger automobiles, a 4,000-lb van or light truck, 20,000-lb school buses, 32,000- to 40,000-lb intercity buses, and 40,000- to 80,000-lb tractor-trailer trucks. Results of these crash tests are summarized. Theory and crash test results are presented to demonstrate the magnitude of the impact forces these traffic rails must resist and how high they must be to prevent vehicle rollover. Typical designs of longitudinal barriers that have been successfully crash tested in accordance with recommended procedures are presented.
The Collapse of the California Sardine Fishery What Have We learned

For a number of years, Federal scientists, employed by an agency whose primary goal was to assist the development of the U.S. commercial fisheries, looked for causes, other than fishing, for the F’acZic sardine’s decline, while California State scientists, charged with the role of protector of the State’s resources, sought reasons to support the premise that ovefishing was having an effect. At the same time, scientists from Scripps Institution of Oceanography looked for fundamental generalizations in theory rather than the activities of man to explain changes in fish populations. For many years, California State personnel struggled without success to gain control over a burgeoning, and later declining sardine fishery. Faced with the possibility that legislation might be enacted, giving the California Fish and Game Commission control over the sardine fishery, the California fishing industry sponsored the formation of the Marine Research Committee to collect and disburse funds and to coordinate and sponsor more “needed” research, thereby forestalling any action to allow management of the fishery to come under the authority of the California Fish and Game Commission. Subsequently, the California Cooperative Oceanic Fisheries Investigations (CalCOFI) was formed, under which cooperative research proceeded. Oceanic conditions (temperature) was found to affect profoundly the distribution, year-class production, and yield of sardines. Nonintermingling or only partially intermingling stocks of sardines have been described. Considerable attention has been focused on the complementary role of sardines and anchovies as competing species acting as a single biomass while competing with each other as part of that biomass. Confirmation of this hypothesis was found to have been based on faulty interpretation of basic data. If such a relationship exists, it still needs to be demonstrated. Density-controlling mechanisms, however, which may be of greater importance, include predation, cannibalism, and other behavioral characteristics. Schooling behavior, for instance, which has evolved through natural selection to decrease mortality from predation, may work toward destruction of the prey species when it is confronted by a fishery which evolves more rapidly than does the species defense against it. A model that is consistent with the results of all the previous studies on the sardine must bring one to the conclusion that the present scarcity of sardines off the coast of California, and their absence off the northwest, is an inescapable climax, given the characteristics and magnitude of the fishery and the behavior and life history of the species.
Global-Local Optimization of Stringer Stiffened Panels for Transportation Aircraft Wings

Higher order effects play an increasingly dominant role in the design of transportation aircrafts with high aspect ratio wings. Considering these effects requires high fidelity methods, which are based on explicitly detailed models. However, for effcient and fast simulation techniques, pre-design of aircraft structures relies on finite element models of significantly reduced complexity This conventional procedure enables a fast solution for large problems, but does not provide enough information for the sizing of the wing panel substructures such as the stringers. In order to cope with strength and stability requirements the detailed sizing of stringer sti_ened panels is necessary. The global-local optimization offers a suitable approach to deal with the detailed models and to enable the fast solution of large problems at the same time. The thesis has been carried on at the German Aerospace Center (DLR) Institute of Composite Structures and Adaptive Systems in Braunschweig. The work presented introduces the framework GLOPTImos, backbone of the multilevel process developed. The wing is globally modeled by finite elements, where the stringer properties are implicitly represented by an equivalent shell layer. Thus the global level is analyzed and optimized to minimize the mass under element stress constraints. Selected wing skin panels are extracted from the global wing and further remodeled with stringers details. Nodal displacement are transferred from the global solution to the local level. The finite element analysis is performed on the selected panels which are mass optimized under additional stability constraints. The global model is then updated with the optimum local level results, and a number of iterative global-local optimization loops executed. The thesis work provides a complete suite of developed tools suitable for automated multilevel optimizations, which minimizes the repetitive time consuming activities required to generate the _nite element models. The method is demonstrated using as design case the F7x wing geometry as global level, and three upper skin blade sti_ened panels remodeled in detail as local level. The global- local process is delivered as an automated package executable in batch mode to minimize the user intervention, and to speed up the computational time.
Niat Beli Sepatu Merek Lokal oleh Generasi Muda: Pengaruh Consumer Ethnocentrism, Perceived Quality, Perceived Price, dan Perceived Brand Image

Indonesia is one of the top 4 world footwear producers. On the other hand, there are many well-known foreign brand shoes in Indonesia. Ventela is one of a famous shoes local brand in Indonesia. The local consumers have preferences concerning the shoe producer country of origin. Local people prefer to buy local brand shoes if they have an ethnocentric taste and good perceptions about the local brand. Therefore, this study aims to determine the effect of consumer ethnocentrism, perceived quality, perceived price, and perceived brand image toward a willingness to buy Ventela shoes. The survey was conducted using an online questionnaire and collected data from 205 young generations. Multiple linear regression in SPSS software was used to analyze the collected data. This study shows that consumer ethnocentrism, perceived quality, and perceived price significantly affected willingness to buy. Meanwhile, the perceived brand image had no significant effect on willingness to buy. Further research is suggested to compare several local fashion brands with different positioning. The results of this study can be used as input for Ventela shoes in facing business competition and business development by paying attention to the variables used.
Five-years Results of Small-incision Lenticule Extraction in High Myopia

Background To investigate long-term refractive visual quality outcomes and vision-related quality of life after small-incision lenticule extraction (SMILE) in the treatment of high myopia.Methods Thirty patients (60 eyes) with high myopia who underwent SMILE more than 5 years previously were selected as the SMILE group. Another 30 high myopia patients (60 eyes) who had worn corrective spectacles for more than 5 years were selected as the control group. In the SMILE group, the postoperative follow-up times were 3 months, 6 months, 1 year and 5 years. The uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent (SE), and ocular axial length (AL) were analysed. The Chinese version of the National Eye Institute Visual Function Questionnaire-25 (CHI-NEI-VFQ-25) was used to evaluate the vision-related quality of life in the SMILE group and the control group.Results In the SMILE group, the mean preoperative SE was -7.29±0.87 D (range -6.00 to -9.125 D). The efficacy index and safety index of SMILE were 1.09±0.18 and 1.19±0.12, respectively. Five years postoperatively, 44 eyes (73%) obtained a visual acuity of 20/20 or better. There were no eyes with CDVA loss of one or more Snellen lines. Forty-nine eyes (82%) and 57 eyes (95%) were within ±0.50 D and ±1.00 D of attempted correction, respectively. Forty-eight eyes (80%) had astigmatism < 0.50 D. The postoperative mean SE values at 3 months, 6 months, 1 year, and 5 years were 0.11±0.44 D, 0.07±0.45 D, -0.02±0.41 D, and -0.15±0.46 D, respectively. No significant change was observed in the ocular axial length from before operation to 5 years postoperatively (26.08±0.96 mm vs 26.01±0.94 mm, p>0.05). Compared to the control group, the SMILE group showed a significantly higher total score on the CHI-NEI-VFQ-25 (90.14 vs 81.43, p < 0.001). Conclusions In the present study, in a long-term follow-up, we demonstrated that correcting high myopia with SMILE is safe, effective, and predictable. In addition, there is slight undercorrection.
Improvement of DLR rotor aeroacoustic code (APSIM) and its validation with analytical solution

DLR's APSIM code was developed for prediction of rotor or propeller noise radiated in the free far-field. APSIM is the abbreviation for "Aeroacoustic Prediction System based on Integral Method". A new formulation based on airloads as input was derived and implemented in APSIM. The number of revolutions used in the input airloads can now be specified. This characteristic is very important for the tail rotor noise computation as the airloads on the tail rotor may not repeat after one revolution due to main and tail rotor interaction. The aeroacoustic results for the 40% scale BO105 main rotor and tail rotor configuration are calculated using both pressure distribution and airloads from DLR's UPM-Mantic code. The results using different aerodynamic inputs are compared. The implementation of the FW-H formulation based on penetrable surface into DLR's APSIM code is discussed. The aeroacoustic benchmark problems based on a point monopole source in various motions were used to validate the implementation. The comparisons were also made with Kirchhoff formulation. Finally, the effect of an open integral surface on the radiated sound field is discussed and suggestions on the future works are then presented.
The Effect of Blast Exposure on Sleep and Daytime Sleepiness in U.S. Marine Corps Breachers

Abstract : Traumatic brain injury resulting from blast exposure is an increasingly common problem among Soldiers returning from combat deployment. In order to understand the extent of damage resulting from blast exposure, this study examined students and instructors at the United States Marine Corps Methods of Dynamic Entry School during a two week training period. The results of the study suggest that actigraphy and subjective sleep measures are sensitive to changes in sleep quality/quantity as well as daytime sleepiness over the training session. The extent to which these changes are associated with blast exposure rather than other factors related to the training period will be explored further in a large scale study of breacher crewmen.
Properties of Stone Mastic Asphalt Slabs Compacted Using a Newly Developed Roller Compactor

Pavement mix design procedures and specifications are usually derived from laboratory experiments conducted on materials that are to be used in the field. Therefore, laboratory experiments should be able to simulate to a high degree the conditions in the field, especially in term of compaction procedures. Stone Mastic Asphalt (SMA) is one type of asphalt mixtures that is highly dependent on the method of compaction as compared to conventional Hot Mix Asphalt (HMA) mixtures. As the future trends in asphalt pavement industry all over the world is gradually changing over to SMA due to its excellent performance characteristics, a suitable laboratory compaction method that can closely simulate field compaction is evidently needed. Therefore, this study is conducted in order to evaluate the Stone Mastic Asphalt (SMA) properties compacted using the newly developed Turamesin and thus to determine the ability and performance of Turamesin as an improved laboratory compaction method. This study comprises of three stages. In Study 1, a literature review was conducted in order to establish suitable methods for slab compaction procedures. Preliminary compactions were then performed and data were analyzed to develop correlation between different compactive efforts and properties of the compacted slabs. From the analysis, 8 kgf/cm2 of applied pressure and 75 numbers of passes of the roller compactor were required to achieve the ideal void content of 4%. Also, Turamesin was found to be capable of compacting slab within duration of 15 minutes, enabling 16 cylindrical core specimens of 100 mm to be cored out. In Study 2, a total of 15 slabs from three different types of asphalt binders, namely Grade 60/70, Grade PG76 and Grade 80/100 were prepared, measured and analyzed for consistency in terms of length, width and thickness. The results have indicated that the variability of the measured parameters of length, width and thickness were generally low as indicated by 0.26%, 0.18% and 1.44% of coefficient of variation respectively. Thus, it can be concluded that the slabs were uniformly compacted in terms of physical dimensions, resulted in average area of 590 mm by 500 mm and thickness ranging from 60 mm to 68 mm. Prior to Study 3, 100 mm and 200 mm diameter cylindrical core specimens were cored out from previously prepared SMA slabs, before being subjected to bulk density, air voids and other performance tests. Based on the analysis, it was found that the SMA slabs have uniformly distributed properties throughout the slabs with low percentage of coefficient of variation. The measured properties tend to agree with the expected performance and comparable to the common SMA mixtures performance. Therefore, it can be concluded that Turamesin was capable in compacting SMA slabs with uniformly distributed properties throughout the slab which indicate the efficiency and outstanding performance of Turamesin.
Six Myths About Digital Skills Training

Abstract : Soldiers entering the U.S. Army today encounter an array of weapons, equipment, and technologies that require information-age, digital skills. As these unique digital systems evolve, trainers are challenged to prepare soldiers to leverage these systems to meet complex and sometimes unanticipated, missions. In order to gain a better understanding of digital skill training, one group of soldiers was followed for almost a year as they experienced Advanced Individual Training, New Equipment Training, and unit training that covered one major hardware/software change and three software upgrades. Findings are based on observations, surveys, and performance on practical exercises. Results identify several misperceptions regarding the acquisition of digital skills and recommendations for modifying training to improve skill acquisition and transfer. For example, digital skills may not be highly perishable. Soldiers retain what they learned during Advanced Individual Training for at least three-to-four months, but many encounter difficulty in transferring what they have learned to a different problem setting. Training that engages the soldier by embedding the experience in a real-world context that requires active problem solving can enhance transfer.

It is suitable for engineers designing wireless network equipment, handsets, data cards, modules, chipsets, and test equipment as well as those involved in designing LTE infrastructure. It would also be of interest to academics, graduate students, and industry researchers involved in advanced wireless communications, as well as business analysts who follow the cellular market.
Guidelines for Design of Flexible Pavement Widening

This guide is designed to assist in the decision-making process concerning the widening of flexible pavements. It offers some recommended investigative and construction alternatives for widening, given different case scenarios, and should serve as a general guideline in that regard. The first step in selecting a widening strategy is to evaluate the existing pavement condition, which can be obtained through the Pavement Management Information System (PMIS). The different sections of this design guide are organized according to recommended investigative methods, subgrade and base stabilization, pavement drainage, equipment options, longitudinal joint construction, jointed concrete pavement, and some construction alternatives, which offer a quick reference for widening alternatives.
