The uneven temporal and partial distribution of water resources in Hellas, and especially southeastern regions, has resulted in the construction of various water systems for collection and storage of rainwater, since their very early habitation. Ever since, technologies for the construction and use of several types of cisterns and other relevant hydraulic strictures have been developed. The main diachronic achievements in rainwater harvesting and use in Hellas from the earliest times of humankind to the present is studied. Emphasis is given to the periods of great achievements such as the Hellenistic and the Roman. The major necessity of water justifies not only the innovations found throughout the historical time-line of these constructions but also the most advanced engineering of each era applied to these constructions. Also, the importance of this hydrotechnology and the concept of the value of water-saving to present and future times is considered. Aspects referring to hygienic precautions for the purity of the water collected and stored are another issue that is worth examining.

The establishment of technology bases required for the development of a fusion demonstration reactor (DEMO) has been discussed by a joint effort throughout the Japanese fusion community. The basic concept of DEMO premised for investigation has been identified and the structure of technological issues to ensure the feasibility of this DEMO concept has been examined. The Joint-Core Team, which was launched along with the request by the ministerial council, has compiled analyses in two reports to clarify technology which should be secured, maintained, and developed in Japan, to share the common targets among industry, government, and academia, and to activate actions under a framework for implementation throughout Japan. The reports have pointed out that DEMO should be aimed at steady power generation beyond several hundred thousand kilowatts, availability which must be extended to commercialization, and overall tritium breeding to fulfill self-sufficiency of fuels. The necessary technological activities, such as superconducting coils, blanket, divertor, and others, have been sorted out and arranged in the chart with the time line toward the decision on DEMO. Based upon these Joint-Core Team reports, related actions are emerging to deliberate the Japanese fusion roadmap.

The strategic establishment of technology bases required for the development of a fusion demonstration reactor (DEMO) has been discussed by joint endeavors throughout the Japanese fusion community. The mission of Fusion DEMO is to demonstrate the technological and economic feasibility of fusion energy. The basic concept of Fusion DEMO has been identified and the structure of technological issues to ensure the feasibility of this DEMO concept has been examined. The Joint-Core Team consisting of experts from the Japanese fusion community including industry has pointed out that DEMO should be aimed at steady power generation beyond several hundred thousand kilowatts, availability which must be extensible to commercialization, and overall tritium breeding sufficient to achieve fuel-cycle self-sufficiency. The necessary technological issues and activities have been sorted out along with 11 identified elements of DEMO, such as superconducting coils, blanket, divertor, and others. These will be arranged within a time line to lead to the Japanese fusion roadmap.

A multi-camera Digital Image Correlation (DIC) systems have been developed to match the specific requirements for measurements posed by building and petrochemical industries. The two most important issues are connected with considerable dimensions of objects and a time line of the measurements. Although DIC provides capabilities of scaling a field-of-view (FOV), dimensions of industrial installations in many cases are too big to be measured with DIC based on a single camera pair. In this paper we present two strategies that can be used for spatial stitching of the data obtained with multi-camera DIC systems, namely a strategy for the case when there are overlapping FOVs of 3D DIC setups and a strategy for the case when 3D DIC setups are distributed and not necessarily have overlapping FOVs. Two practical applications of the multi-camera DIC system are described in order to show its feasibility in industry.

A tanulmány a japán vállalatvezetés kialakulásával, történelmi és társadalmi gyökereivel, valamint intézményesülésének vizsgálatával foglalkozik. Első részében a szerző áttekinti, milyen főbb földrajzi és történelmi tényezők, körülmények játszottak szerepet a japán vezetési gyakorlat formálódásában. Ezt követően egy meghatározott történelmi idősíkon követi nyomon az amerikai menedzsmenttörténet egyes korszakainak megfelelő japán változásokat, vállalatvezetési reakciókat – kezdve a klasszikus menedzsment tanaitól (taylorizmus, racionalizálás...) egészen a mai kor globális versenye által támasztott követelményekig. Rámutat arra, mikor és miért késtek fontos váltások Japánban a vállalatvezetésben élenjáró Amerikához képest, majd értékeli ennek elméleti és gyakorlati jelentőségét. Szándéka szerint ez a történelmi áttekintés képez alapot napjaink Japánnal kapcsolatos gazdasági-társadalmi eseményeinek, reformjainak értékeléséhez is. ____ This paper describes the development, the roots and the process of institutionalization of corporate management in Japan. In the first half the author will look at what major geographical factors and cultural characteristics could play a role in shaping the Japanese management practices. Then, along a historical time line, he scrolls through the Japanese reactions given to each of the major American historical eras: from the classical management (Taylorism, rationalization...) up to the challenges of today’s global competition. It is pointed out where paradigm shifts were delayed compared to the US, and while providing potential reasons, the author evaluates the significance of the differences. This historical comparison ought to provide a basis and scope of understanding for today’s events and ongoing reforms in Japan.

To find the best all time college coach, we analyze synthetically the college coaches of all time in the field of football. First, we collect the necessary data and build the index set which is composed of Win-Loss percentage, SRS, SOS, Championship index and Games. After screening the data with the vital indexes like Win-Loss percentage and Games, we select the coaches who are qualified to be the best one. In view of the effect of the time line horizon, we rank the coaches annually with grey relational analysis model based on Entropy Method. Since there are only a portion of coaches to be ranked in one year, we set up top coach network to link all coaches, in which vertexes refer to coaches. Applying the network, we calculate the prestige score and correct it by considering the effect of the strength of teams. With the help of prestige score, we gain the final rank.

In order to evaluate coaches, this paper established the model of comprehensive evaluation based on analytic hierarchy process (AHP). Firstly, I establish the hierarchical structure of the system; Secondly, for researching the influence of time line horizon in analysis, I divided coaches into several groups by their career time and calculated the weights of indicators of each group using entropy weight method; Finally, calculate the weight between the criteria layer and objective layer. Female coach data is difficult to find, so I select 100 college basketball male coach data. Put the data into model and get a score. The score showed the final result which can give us a sort of reasonable coach list. This model can reduce the influence of different time periods for evaluation of the coach.

The coloured Petri net formalism has been recently used to analyse and optimise manufacturing systems making use of the state space (SS) analysis. This approach has great potential for scheduling and production planning purposes when it is properly implemented. In this article, an improved version of the algorithm known as the time line search for optimising the makespan of manufacturing models is presented. The algorithm has been developed for the use in a compact SS of coloured Petri net models in order to analyse the highest possible number of manufacturing configurations for the improvement of the makespan of a production system. The proposed algorithm can be used for the developing of decision support tools in manufacturing or operational decision-making.

A study was conducted to construct a job exposure matrix for the roofing granule mine and mill workers at four U.S. plants. Each plant mined different minerals and had unique departments and jobs. The goal of the study was to generate accurate estimates of the mean exposure to respirable crystalline silica for each cell of the job exposure matrix, that is, every combination of plant, department, job, and year represented in the job histories of the study participants. The objectives of this study were to locate, identify, and collect information on all exposure measurements ever collected at each plant, statistically analyze the data to identify deficiencies in the database, identify and resolve questionable measurements, identify all important process and control changes for each plant-department-job combination, construct a time line for each plant-department combination indicating periods where the equipment and conditions were unchanged, and finally, construct a job exposure matrix. After evaluation, 1871 respirable crystalline silica measurements and estimates remained. The primary statistic of interest was the mean exposure for each job exposure matrix cell. The average exposure for each of the four plants was 0.042 mg/m(3) (Belle Mead, N.J.), 0.106 mg/m(3) (Corona, Calif.), 0.051 mg/m(3) (Little Rock, Ark.), and 0.152 mg/m(3) (Wausau, Wis.), suggesting that there may be substantial differences in the employee cumulative exposures. Using the database and the available plant information, the study team assigned an exposure category and mean exposure for every plant-department-job and time interval combination. Despite a fairly large database, the mean exposure for95% of the job exposure matrix cells, or specific plant-department-job-year combinations, were estimated by analogy to similar jobs in the plant for which sufficient data were available. This approach preserved plant specificity, hopefully improving the usefulness of the job exposure matrix.

The scheduling of flexible manufacturing systems has received great importance as a key factor to improve competitiveness in industrial systems. In this paper it is presented an improvement of a two-phase optimization algorithm for Timed Coloured Petri Nets. The algorithm explores the compacted state space of manufacture models in order to find particular objective states giving the sequence of events that drives the model to the objective state with optimal times. The proposed approach is improved with the implementation of a time driven algorithm based on the shortest processing time which defines the successor states to be evaluated when time is used as a cost function. The developed algorithm is tested with benchmarks problems to demonstrate its efficiency to cope with models of combinatorial nature.

Distillation Research and Development is moving rapidly with the utilization of computational fluid dynamic (CFD) modeling. Previously, a potential fractionation application would first be developed and fabricated. Then many hours of pilot plant testing would be required to finalize the design. The time line for the development of new distillation equipment has been reduced, leading to advances in fractionation equipment. Current applications of trays, packings, distributors and feed inlets can be optimized utilizing CFD modeling. CFD Modeling has improved the current generation of fractionation equipment. This modeling is also particularly important in maximizing capacity in tower revamps where the diameter of the tower is fixed. This paper will review the current-generation fractionation equipment and the utilization of the same in the petroleum refining industry.

In fall 2013, the Office of Summer and Winter Programs at the University of Connecticut (UConn) was charged by the Office of the Provost with creating a new, intensive summer program designed specifically for incoming freshmen and transfer students, to run for the first time the following summer. The program, under the name UConn First Summer, was intended to achieve two primary purposes: to offer incoming students a head start on their academic work and, no less significantly, to immerse them in a campus experience aimed at building college skills. This paper outlines the process of building the program, leading up to the resulting program launch in July 2014. The paper lays out the various pieces of this process, including marketing, curriculum development, and event and activity planning. A significant part of the paper discusses how each stage of the program build required addressing a range of challenges, resulting primarily from institutional obstacles and the compressed time line for the program’s creation., Summer Academe: A Journal of Higher Education, Vol 9 (2015)

As a floriculturist, when I first decided to grow strawberries (Fragaria ×ananassa) in the greenhouse, I thought it would be a snap. After all, I could practice what I preach to my classes in that I would use all the sustainable growing tricks from floriculture, create a production time line and it would be ready, set grow. However, moving a field-grown summer crop into a greenhouse as a winter crop was not the same as moving a winter greenhouse-grown crop outside for the summer. Not only were the plants typically grown in lush field soil, but also the fertilizer recommendations were not directly translatable (i.e., parts per million nitrogen). The pesticides used were not licensed for greenhouses and of course, there were no clues as to schedules of what to do when. Finally, there were the mystery problems that occurred. With high gas prices and the interest in local food production, it seems probable that over the next 5 to 10 years, more and more fruit, vegetables and even nut plants will be moved into greenhouse and high tunnel production. The purpose of this article is to identify the kinds of information needed to make a “smooth” transition from field to greenhouse for alternative crops, like strawberries, grown during nontraditional seasons.

The increasing flexibility in industry leads to an ecosystem of change, affecting the balance of processes and technology as well as the developers who have to cope with the change. Furthermore, the change itself might impact the ability to use quantitative methods to learn from previous experience. The goal of this study is to better understand the ecosystem of mutual impacts and changes of process and technologies as well as how developers perceive a technology setting and deal with its change. Therefore, we conducted a case study at Ericsson, performing a series of interviews among 6 employees (senior developers and architects). We identified a time line of changes that happened over 7 years. A set of observations about the relation between processes and tooling, and observations about developer's perceptions of the technology settings, and their strategy to deal with these changing technology settings. We discuss how the observed change impacts the ability to perform quantitative evaluations of technology and processes. The findings show that a bad choice of technologies can lead to unexpected impact on team dynamics. Furthermore, change happens so regular that it needs to be considered when collecting data for a quantitative evaluation of, eg, productivity.

This paper presents a Simulated Annealing based heuristic that simultaneously considers both setups and the stability of parts usage rates when sequencing jobs for production in a just-in-time environment. Varying the emphasis of these two conflicting objectives is explored. Several test problems are solved via the Simulated Annealing heuristic, and their objective function values are compared to solutions obtained via a Tabu Search approach from the literature. Comparison shows that the Simulated Annealing approach provides superior results to the Tabu Search approach. It is also found that the Simulated Annealing approach provides near-optimal solutions for smaller problems.

Centro de Investigación en Diseño Industrial de Productos Complejos; Argentina Abstract: The aim of this work is to present the different aspects of modern high complexity electric beds of the period 1940 until 2000 exclusively. The chronology of the product has been strictly divided into three big stages: electric and semi-electric beds (until the 90’s), mechatronic beds (90’s until 2000) and, mechatronic intelligent beds of the last 15 years. The latter are not considered in this work due to the extension for its analysis. The justification for classifying the product is presented under the concepts of medical, assistive and mobility devices. Relevant aspects of common immobility problems of the different types of patients for which the beds are mainly addressed are shown in detail. The basic functioning of the patient’s movement generator and the implementation of actuators, together with IT programs, specific accessories and connectivity means and network-communication shown in this work, were those that gave origin to current mechatronic beds. We present the historical evolution of high complexity electric beds by illustrating cases extracted from a meticulous time line, based on patents, inventions and publications in newspapers and magazines of the world. The criteria adopted to evaluate the innovation were: characteristics of controls; accessories (mattresses, lighting, siderails, etc.), aesthetic and morphologic properties and outstanding functionalities

The CO 2 concentration in the atmosphere has increased due to the combustion of fossil fuels and this is causing concerns of global warming. At present there is no cost effective CO 2 control and capture technologies available at scale for coal-fired plants. The US Department of Energy (DOE) National Energy Technology Laboratory (NETL) has initiated a research and development program to develop advanced CO 2 capture and compression technologies for both existing and new coal-fired power plants. The goal is to achieve 90% CO 2 capture at less than 35% increase in cost of electricity (CCE) at a commercial scale by the year 2020. The time line for developing a system for Carbon Capture and Storage (CCS) is shown in figure. This chapter outlines an overview of the technologies being investigated for CO 2 capture and sequestration in anticipation of future CO 2 emissions legislations. The different elements in developing a CCS is explained with block diagrams throughout the chapter. The success of CCS depends on the ability to measure the amount of CO 2 at a particular site, to confirm the stored CO 2 is not harming the eco-system and the ability to mitigate any impact associated with CO 2 leakage. References for further reading are given.

The network sensitivity factors are used for line flow estimation. Most of them are applied in conjunction with demand change limits under certain conditions. In this paper, a new factor, called the Z-bus distribution factor, is proposed to improve some deficiencies in the use of these sensitivity factors. A two-step real-time approach, combining the generalized generation shift distribution factor and the proposed Z-bus distribution factor, is organized to calculate line flows using an algorithm without running a load flow. Test systems with arbitrary demand changes in each bus are simulated and demonstrated to prove the outstanding characteristics of the proposed approach. The solution accuracy is good compared with that of the fast decoupled load flow method, with a much shorter execution time. It is very suitable for security evaluation and contingency analysis in real time.

Dairy farms that are in the transition of increasing herd size and adapting new technology are challenged with the increased capital investment of new barns and milking center for the new dairy system. Remodeling a tie stall or stanchion stall barn into a milking center is a key part of the transition from a relatively labor intensive stall barn system to a more labor efficient milking parlor and cow housing system. One major reason for remodeling an existing barn rather than build a new parlor is to continue to use some of the existing infrastructure rather than replace it at a new site. Sweat equity can also keep costs under control. From a design and construction perspective, the milking center is one of the more complex facilities on the farm. The construction requires coordination of multiple contractors. The project also needs to have a time line that is realistic and definite. Communication and coordination between the owner and contractors can eliminate mistakes, reduce delays and keep the project on schedule. The construction process for remodeling the tie/stanchion stall barn space into a milking center is discussed. Structural changes, concrete demolition and forming, milking stall, and milking system installation options are also discussed.

Operating spacecraft at End -Of -Life (EOL) presents a lot of challenges. For spacecrafts with multi -tank propulsion system, one of the problems i s propellant migration between tanks due to temperature difference between tanks, so called thermal pumping. Propellant migration can deplete one of the tanks even though the total propellant load of the spacecraft does not indicate any possibility of tank depletion. The thermal pumping should be taken into consideration at EOL when amount of propellant migrating in and out of the tank is comparable with propellant load of a single tank. The paper discusses an Active Propellant Management (APM) approach t o control propellant migration in order to reduce risk of an accidental depletion of a single tank in multi -tank propulsion system. A reduction of the propellant migration is accomplished by using tank heaters to control propellant movement between tanks. The paper discusses possible APM implementations, like temperature difference driven vs. time line driven. It shows that the most common approach, namely, temperature difference driven APM may lead to a more dangerous propellant distribution than it tri es to mitigate. The paper also discusses effect of propellant migration on re -pressurization procedures for satellites with blow -down multi -tanks propulsion system.

At the University of Texas at Austin, senior electrical engineering majors design a number of lab reports which enable them to practice writing skills needed by engineers in industry. Before designing these reports, students are given instruction in various aspects of writing. An evaluation guide not only pinpoints all possible errors in the design of the report but also serves as a checklist to be used while producing the report. The stages of designing the report are made analogous to the states in a laboratory project that moves from research and design to analysis and implementation. The author describes the makeup of this course and presents a flow chart and a time line for producing laboratory reports. >

With increasing expectations for yield and learning rates, a refined method of yield excursion determination is required. This need is met through the use of yield trend box plots with overlaid wafer map composites by quartile. It was found that this method quickly identifies excursion lots based on spatial non-randomness in addition to yield and its variation. Once identified, lots or wafers with spatial anomalies can be further studied using correlation utilities, time line studies, commonality analysis, and spatial signature matching.

Optimization of quality, cost, and time is still one of the industry’s general objectives. We present here a malfunction approach for decision making processes. This allows the evaluation of decisions and then, the optimization of decision making processes. We introduce the concept of Decision Time Line (DTL) which models the decision process from the request to the answer. In addition to this temporal description of malfunctions, we highlight that it is possible to give a characterization of these malfunctions. Then, we focus our research works more particularly on decisions considering the choice of actors in product design processes. We propose, on one hand, an evaluation of malfunctions appearing in such decisions and, on the other hand, a methodology that helps to find appropriated recommendations to avoid them.

A resistência ao trincamento por fadiga afeta diretamente a vida útil dos pavimentos asfálticos e, no intuito de melhorar o desempenho das misturas asfálticas à fadiga, aditivos têm sido incorporados ao ligante asfáltico. O enrijecimento do ligante asfáltico provocado pelos aditivos, via de regra, aumenta a resistência à deformação permanente, mas, por outro lado, ainda não se sabe precisamente qual o efeito deles sobre a resistência à fadiga e ao trincamento térmico dos ligantes asfálticos. Um dos principais desafios atuais para os pesquisadores é o desenvolvimento de um procedimento rápido para a determinação da resistência à fadiga dos ligantes asfálticos em laboratório. Na linha do tempo do desenvolvimento de ensaios de fadiga, Bahia et al. (2001) propuseram o ensaio de varredura de tempo (time sweep). Em seguida, Johnson (2010) desenvolveu o ensaio LAS (Linear Amplitude Sweep), no qual é ajustado um modelo que correlaciona a vida de fadiga do ligante asfáltico com a carga aplicada. Mais recentemente, Hintz (2012) propôs algumas mudanças no procedimento do ensaio LAS, estabelecendo o LAS modificado e um novo método de análise dos resultados. Tendo em vista tais desenvolvimentos recentes, este trabalho tem como objetivo apresentar os procedimentos de ensaio mais recentes (time sweep, LAS original e LAS modificado) para caracterização do comportamento à fadiga dos ligantes asfálticos, ilustrando a sua aplicabilidade na caracterização de ligantes asfálticos modificados.

On-Site Inspection (OSI) Workshop-5 met 8-12 November, 1999 in Farnborough, UK and was hosted by the Defence Evaluation and Research Agency (DERA). The purpose of the workshop was to provide guidance on OSI Operational Manual (OM) development for Working Group B (WGB) of the CTBT Preparatory Commission (PrepCom). The two main topics of the workshop involved logistics/preparatory activities for the pre-inspection phase and in-depth examination of technology application during the initial and continuation phases of an OSI. Reports from the PTS-sponsored Kazakhstan OSI experiment set the tone for the discussions of logistics and preparatory activities. The most important recommendation coming out of the experiment and workshop discussions is a need for Working Group A to develop specific administrative and financial rules regarding OSIs and define the status of inspectors and inspector assistants with respect to the CTBTO. There was also extensive discussion of a need for Working Group B to develop and/or adapt safety standards. With respect to OSI preparations, the group agreed that the time line and quick response required by an OSI necessitate development of special procedures; standing arrangements and/or advanced parties are suggested as one possible approach and a list of relevant issues has been initiated. Amore » chart was developed that outlines the various elements of logistics required for an OSI that can serve as a basis for development of checklists, databases, and other preparation activities. Technology presentations and discussion focused on three major areas: phenomenology, synergy, and specifications.« less

Publisher Summary This chapter focuses on keys for the successful implementation of an improvement program. Improvement is prevented due to adversarial relationships between the functional areas of the plant. These relationships include the friction between management and the hourly labor force, and between production and the maintenance department. Almost all functional groups in the plant have less-than-adequate relationships with all other groups. Selling the plan to at least four levels must be accomplished for a program to succeed: corporate management, plant management, division management, and the hourly work force. Without a good plan, most programs fails within the first year. The plan must include well-defined goals and objectives. Most companies cannot afford to make the major capital investments that are required by improvement programs. Therefore, the program should use a phased approach. Specific tasks should be defined in a logical sequence that will minimize investment and maximize returns. Return-on-investment (ROI) must be the driving force behind time line and implementation approach.

The objective of this report is to describe and discuss the thermal design, analysis and flight data of various experiments flown through the Hitchhiker (HH) Program at NASA Goddard Space Flight Center, along with a comparison study of the HH Avionics for several missions. The research entails the thermal design of the experiments, the shuttle mission profile (attitude time line) and actual flight data. One interesting flight occurred for STS-74 and the HH GLO-4/PASDE Payload (GPP). This was a MIR docking mission which required the Orbiter to fly in extreme solar inertial attitudes conducive for MIR, attitudes never flown prior to this mission. PASDE, mounted in three different bays of the Orbiter, allowed for a comparison of attitude with bay location.

The scheduling of tracking and surveillance looks for multifunction radar is considered. A technique called the sequential scheduler is proposed, whereby tracking looks and high-priority surveillance looks are scheduled first, and lower-priority surveillance looks are then scheduled to occupy gaps in the radar time line. A method called the two-slope benefit function (TSBF) sub-scheduler is used and requires that each tracking look and high-priority surveillance look has a benefit function, which specifies benefit as a function of start time. This method accounts for both look priority and target dynamics in formulating a look schedule. If the radar is overloaded with tracking look requests, the TSBF sub-scheduler down-selects a set of looks that can be scheduled, using a method that favours higher priority looks. Looks are scheduled to maximise the total benefit, and it is shown that the resulting maximisation is equivalent to a linear program which can be solved efficiently using the simplex method. A technique called the gap-filling sub-scheduler is used to schedule lower-priority surveillance looks. An example is presented which illustrates the properties of the sequential scheduler.

The present telescience testbed study was conducted to evaluate the feasibility of physiological experimentation under restricted conditions such as during simulated weightlessness induced by using a water immersion facility, a reduced capacity of laboratory facilities, a delay and desynchronization of communication between investigator and operator, restrictions of different kinds of experiments practiced by only one operator following a limited time line and so on. The three day's experiments were carried out following the same protocols. The operators were changed every day, but was the same the first and the third day. The operators were both medical doctors but not all round experts in the physiological experimentation. The experimental objectives were: 1) ECG changes by changing water immersion levels, 2) blood pressure changes, 3) ultrasonic Echo-cardiographic changes, 4) laser Doppler skin blood flowmetry in a finger, 5) blood sampling to examine blood electrolytic and humoral changes. The effectiveness of the testbed experiment was assessed by evaluating the quality of the obtained data and estimating the friendliness of the operation of the telescience to investigators and operators.

Publisher Summary This chapter discusses the modeling scenarios for action. To bring human performance (or other) models to bear at design time, it is necessary to predict the interactions of pilot, aircraft, and environment. This can be done roughly, and at great time and expense, by humans in simulators. It would be more effective if a greater portion of the task could be done analytically and computationally. Computational methods have potentially great advantages over empirical human simulations. Pilot behavior depends on higher-order perceptual and mental functions—the part of the system that is most difficult to model. The standard technique that has evolved to model pilot action is based on fixed scenarios. Each scenario consists of a list of actions—fixed by the analyst—that accomplishes some mission. The actions are then used as input for later analyses. From the detailed scenario, the analyst could then pursue other time line construction, workload analysis, anthropometric analyses, or analysis of eye-scanning patterns. Several techniques exist that are potentially applicable for setting more complex scenarios of high-level interactions between the pilot and the environment.
