This paper introduces a new method for the communication between human and product model entity definition processes. As product definition is moving into modeling in industrial product lifecycle management (PLM) systems, and built-in knowledge and intelligent computing content of product models increase, development of product modeling faces new challenges. More often, knowledge content is not in accordance with authorized human intent and different intents of different authorized humans for the same task are not in harmony. At the same time, authorized human needs help to understand decisions of other humans at application and modification of existing entity definitions in product model. The authors of this paper found the answer for the above challenges in a new human-model generation communication which extends the conventional product feature definition to higher level definition of objectives and allows for harmonizing different human intents. This communication applies higher level connection of human and product object generation process by knowledge based contextual chain in which model entities are more appropriate for knowledge content based decisions as the currently applied knowledge ware features. The proposed communication is devoted as extension to currently applied one so that the new decision assistance can be integrated with the well proven feature driven current industrial modeling.

Abstract This article writes engineers into the history of Lebanese political-economic thought. Historians of Lebanon's postindependence period have emphasized how a narrow, elite “consortium” espoused a national ideology that authorized laissez-faire monetary and trade policies. These intellectuals and businessmen invoked environmental determinism to claim that trade, tourism, and services were Lebanon's national vocation. This article reveals that engineers formed an influential and underexamined countercurrent advocating statist developmentalism. Engineer-bureaucrats saw the postindependence era as an opportunity to claim their profession's status and redefine bourgeois culture and its relationship to governing institutions according to their conceptions of modernity. By reinterpreting the consortium's environmental narrative of Lebanese history, the hydrological engineer Ibrahim Abd-El-Al portrayed rational development of water resources and agriculture as an organic expression of national identity. These efforts cultivated a critical and technically literate reading public that favored statism and shaped how that public understood their national subjectivity and relationship to the natural world.

Full textAbstract:
This paper outlines the basic development background of the Class 58 locomotive and main design features, with areas of design development resulting from the introduction into service in 1983–85 of the first build of thirty-five locomotives and detail changes in design being applied to the second batch of fifteen locomotives authorized in 1984. This locomotive design developed from a joint exercise between British Rail Engineering Limited (BREL) and the then Chief Mechanical and Electrical Engineer (CM and EE), British Railways Board (BRB) in 1977 which resulted in BREL fully participating in the design development to utilize modern manufacturing methods. The Class 58 was designed by BR specifically for freight duties and is based on a strength underframe with bonnet-type structure and equipment in modular assemblies.

Full textAbstract:
The U.S. Army Corps of Engineers (USACE) is responsible for the maintenance of federally authorized navigation channels and associated infrastructure. As such, USACE requires objective performance measures for determining the level of service being provided by the hundreds of maintained navigation projects nationwide. To this end, the U.S. Army Engineer Research and Development Center partnered with Texas A&M Transportation Institute to develop a freight fluidity assessment framework for coastal ports. The goal was to use archival automatic identification system (AIS) data to develop and demonstrate how ports can be objectively compared in relation to fluidity, or the turnaround time reliability of oceangoing vessels. The framework allows USACE to evaluate maintained navigation project conditions alongside port system performance indices, thereby providing insight into questions of required maintained channel dimensions. The freight fluidity concept focuses on supply chain performance measures such as travel time reliability and end-to-end shipping costs. Although there are numerous research efforts underway to implement freight fluidity, this is the first known application to U.S. ports. This paper covers AIS data inputs, quality control, and performance measures development, and also provides a demonstration application of the methodology at the Port of Mobile, Alabama, highlighting travel time and travel time reliability operating statistics for the overall port area. This work provides foundational knowledge to practitioners and port stakeholders looking to improve supply chain performance and is also valuable for researchers interested in the development and application of multimodal freight fluidity performance measures.

Full textAbstract:
This article researched the security and application of smart locks in Internet of Things environments in the domain of computer and engineer science and symmetry. Smart locks bring much convenience for users. However, most smart lock systems are cloud-based and it is problematic managing and enforcing the permissions of an authorized device if the device is offline. Moreover, most smart lock systems lack fine-grained access control and cascading removal of permissions. In this paper, we leverage attribute-based access control mechanisms to manage the access of visitors with different identities. We use identity-based encryption to verify the identity of the visitor. In our proposed system, the administrator uses the policy set in the smart lock to implement access control on the device side, which reduces the dependence of access control on the server. We set attributes such as role, time, date, and location to have fine-grained control over access to different permissions and roles that might appear in the house. And the scheme provides the cascading delete function while providing the group access function. Our solution considers multiple roles in the home as well as hierarchical management issues, and improves the applicability of the smart lock system in complex residential and commercial situations. In the experimental section, we show that our system can be applied to premises with many different inhabitant identities.

AbstractMilitary actions generally unfold rapidly in different operational environments for which the commanding officer has assess the bearing capacity of the prestressed concrete bridges existing in the country’s road network. The bearing capacity is the maximum weight of the predetermined constitution convoy, which may safely circulate on the bridge, in stable conditions, considering the physical condition of the bridge. The paper shows that the bearing capacity will be assessed only through a technical analysis performed by an authorized expert together with a military engineer specialized in genius. This experts report will compare the initial condition of the bridge to the present one. The initial condition is based on the research of the execution design; the year of elaboration; the standard loadings at the moment; proprieties of the used building materials; execution modality, possible alterations occurring during execution as to the initial project. These data, together with the road traffic census, can be obtained from the company administrating the road network where the bridge is located. The current state to be assessed through analysis, calculation and static loading tests, showing if the capacity of the bridge can to support the increase of traffic military vehicle loading and reduction of the bearing capacity due to fatigue phenomena in the reinforcement. The paper proposes that authorities draw up and approve a standard concerning the verification periodicity of the bearing capacity in the existing prestressed concrete bridges.

INTRODUCTION:Chronic Pain (CP) is the uncontrolled pain that affects patients for a long time. CP can be caused by many conditions, sometimes still poorly understood, and its levels can vary from moderate to intense. The management of resistant CP requires a stepwise approach and spinal cord stimulation (SCS) could be considered an extreme strategy. With the aim of ensuring the economic sustainability, the Veneto Region usually establishes rigorous access criteria to high-cost medical devices through its Regional Technical Committee on Medical Devices (CTRDM) and a Health Technology Assessment (HTA) procedure.METHODS:The Regional Health Technology Assessment Unit (CRUF) conducted through Pubmed a literature review of randomized controlled trials, systematic reviews, meta-analysis on SCS published from March 2006 to February 2016. International and national clinical guidelines were included in the analysis as well. The regional multidisciplinary Working Group on CP, which involved local clinicians, pharmacists, clinical engineer and health economist, discussed the collected evidence by consensus. Final recommendations on the appropriate use were submitted to the CTRDM for final approval.RESULTS:The regional guidance describes the type of pain that can be treated with spinal neurostimulators and the criteria which determine the success of the test procedure. A comparative analysis of spinal neurostimulators available on the market and related patients eligibility criteria have been also included. Moreover, the guidelines stated a list of compulsory requirements in order to become a regional center authorized in performing spinal neurostimulation procedure. Finally, the document describes some indicators for appropriateness monitoring. The CTRDM approved the final version in October 2016.CONCLUSIONS:The regional guidance on SCS aims at ensuring the appropriate use of neurostimulators in patients affected by resistant CP. The strict monitoring of agreed indicators is essential for appropriateness and consequently the sustainability of medical devices expenditure throughout the Regional Health Service.

Full textAbstract:
Adhesive bonding is increasingly being used in industrial applications mainly due to its adaptability and ability to reliably join a wide range of materials. Numerous industrial sectors have now adopted adhesive bonding as a key manufacturing technology, with the automotive industry being the leader in adhesive usage. This is a key sector for the European Union (climate and energy policy, which has established a target of improving energy efficiency in the European Union by 20% by 2020. Consequently, this industry is constantly demanding lighter, stronger, more durable and more environmentally friendly materials. The increasing popularity of this technology is linked to the noteworthy benefits related with its application, compared to traditional joining process, such as welding or mechanical fastening process. With the increasing popularity of such joining techniques comes the necessity to train qualified professionals. The European Welding Federation developed a harmonized qualification system, which divides the training process into 3 levels: European Adhesive Bonder (EAB), Specialist (EAS) and Engineer (EAE). Currently, in Portugal, the first level of training, corresponding to European Adhesive Bonder is already in operation. The EAB level is accredited by the European Welding Federation (EWF) and therefore meets the requirements of EWF-515r1-10 and EWF-515r2-19 to which the Faculty of Engineering of the University of Porto is bound as a result of the accreditation as an ATB (Authorized Training Body). This training is targeted for professionals using adhesive bonding technology and professionals who do not currently use this technology but want to use it, and as such has a strong practical component. In Portugal, since 2016, three EWF certified editions have been held, with a high approval rate and met the expectations and objectives of the participants.

Abstract Thousands of permit applications are filed annually with the U.S. Army Corp of Engineers, requiring significant review efforts to ensure that applications conform to regulations, and that proposed activities avoid, minimize, and compensate for stream and wetland impacts. However, the effectiveness of this approach remains uncertain. We evaluated the effectiveness of those regulatory efforts using newly installed stream–road crossings as a case study because crossings are pervasive on the landscape and many U.S. Army Corp of Engineers jurisdictions have requirements that are aimed at minimizing crossing-induced impacts to fish passage. Specifically, we assessed whether requirements intended to facilitate fish passage were implemented, whether requirements resulted in fish-passable stream–road crossings, and whether the amount of construction-related stream impact that was authorized by permits corresponded to the amount of compensation that was required. Our analysis is devoted solely to stream–road crossings in Georgia that are permitted under nationwide permits, the permit type commonly used to authorize activities in streams throughout the United States. We found that no new crossings conformed entirely to the requirements intended to avoid and minimize impacts to fish passage. The measured total stream impact length in this study was 46.0% higher than the amount of impact proposed in permit applications for perennial streams, and 23.7% higher for intermittent and ephemeral streams. Only 30.6% of the perennial stream length affected in this study received compensation for impacts even though 90.9% of impacts qualified. Collectively, these results indicate that regulations and mitigation policies are not having their intended effects of providing fish passage or preventing net loss of streams in Georgia as required under the Clean Water Act. We recommend that decision makers undertake a more geographically comprehensive evaluation of stream impacts that are authorized by permits to thoroughly evaluate regulatory effectiveness and impacts to fish passage.

Full textAbstract:
When combatting allegations of copyright infringement, the defendant can argue that the copyright holder authorized the activity at issue, either expressly or implicitly. Exclusive rights under copyright have a common constituent: they represent activities that the copyright holder can authorize or prohibit, authorization being necessary to avoid liability for infringement. Authorization from the copyright holder may be explicit and not raise interpretative difficulties, or it may be implied. The doctrine of implied consent has not received harmonization at EU level but can be found in national laws with regard to interpreting a contractual relationship or conduct. Written agreements may include implied contractual terms and in this context, the implied license doctrine is viewed as a ramification of contract law. But implied authorization may be assumed even in the absence of an agreement or prior communication, where the conduct of the copyright holder gives the impression that a particular activity is permitted. This understanding of implied consent can be traced to German jurisprudence and a body of recent cases that have affirmed the existence of implied authorization where copyright holders did not signify their refusal to consent to a specific activity e.g. by not enacting access control mechanisms in their online content. The judicially created doctrine of ‘implied consent’ is crucial to the functioning of essential Internet facilities such as search engines. This chapter discusses the scope of this doctrine, its applicability to other Internet services, its potential to serve as a defensive rule, and the way in which Svensson can be read as introducing an implied consent defence into EU copyright law.

In the hot, dry summer of 1858, the Thames was a stew of sewage that festered in the sun, giving off an unbearable stench. “We believe this to be the uncleanest, foulest river in the known world,” wrote a London pundit in July. “There you shall see in the brief space of half an hour and two or three miles, a hundred sewers disgorging solid filth, a hundred broad acres of unnatural, slimy chymical compost . . . The water—the liquid rather—is inky black.” Dockworkers suffered nausea, headache, sore throats, temporary blindness—some of them fainted from breathing in the river’s aroma. In the newly rebuilt Houses of Parliament, on the riverbank, legislators choked on what the press labeled “the Great Stink.” The Thames had been badly polluted for decades, but the heat and low water that summer brought the situation to a crisis. Benjamin Disraeli, leader of the House, held a handkerchief over his nose as he fled from the Chamber, complaining that the Thames had become a “Stygian Pool.” In July 1858, he introduced a law that authorized the construction of a costly new sewer system, designed by engineer Joseph Bazalgette, that would carry London’s waste downstream of the city. Britain’s rivers were overwhelmed with sewage, its cities bursting at the seams. Between 1801 and 1841 London’s population had grown from 958,000 to 1,948,000. Numbers of people living in smaller cities like Leeds, Bradford, and Huddersfield doubled or tripled in the same span of time. While the same pattern held in other European and American cities, geography made the problem more intense in Britain, where the rivers were too small to carry off the wastes of the towns that sprouted on their banks. In 1885, engineer James Gordon estimated that dumping the raw sewage of the major towns along the Rhine would give that river a concentration of only one part sewage per 2,345 parts water. The lower Lea, a tributary of the Thames whose upstream flows had been diverted to provide drinking water for London, was by contrast composed of two- thirds sewage.

Ironmakers in the Middle Atlantic states used canals and railways to reduce costs and expand the scale of production with new techniques based on mineral-coal fuel beginning in the 1820s. Salisbury forge and furnace proprietors, who still had teamsters hauling ore, fuel, and metal along dirt roads with wagons in summer and sleds in winter, knew that improved transportation systems would help them get their products to outside buyers. They were less aware that canals and railroads would eventually force them to confront new techniques adopted by ironmakers outside their district. Entrepreneurs in northwestern Connecticut had become interested in waterways as early as 1760, when they wanted to improve the Housatonic’s channel north to Massachusetts in order to float logs downriver to their sawmills. Although the General Assembly authorized a lottery to raise £300 for the project in 1761, the promoters accomplished nothing. The start of construction on the Erie Canal stimulated interest in building a canal along the Housatonic River that would open new markets for the northwest’s ironmakers. Urged on by John M. Holley and others, the Ousatonic Canal proprietors organized a company in 1822 to build from tidewater to Stockbridge, Massachusetts. However, when canal engineer Benjamin Wright’s survey showed the company would have to build enough locks to raise boats a total of 604 feet as they traversed the canal, the project’s supporters backed out. The promoters of the Sharon Canal project, intended to start in Sharon and go down the Oblong River into New York and thence follow the route later used by the Harlem Railroad, accomplished even less. John M. Holley had experienced railroad travel on his 1831 trip to Harpers Ferry. He and his neighbors realized that a railway up the Housatonic valley would gather traffic from the region’s ironworks and, with a connection to the Western Railroad in Massachusetts, open the first year-round route from New York City to Albany. (The railroad along the Hudson River between New York and Albany did not open until 1851.) Several of the region’s ironmasters, including J. M. Holley’s son A. H. Holley, helped raise funds for the construction of the Housatonic Railroad when the state issued a charter in 1836.

The purpose of UbiPOL project is to develop a ubiquitous platform that allows citizens be involved in Policy Making Processes (PMPs) regardless of their current locations and time. However, literature highlights one of the foremost reasons that make citizens de-motivated in engaging themselves in policy making—the ignorance of germane policies and PMPs within the government organisations. It is highly suggested that while more citizens find connections between their everyday life activities and pertinent government policies, the more they become pro-active or motivated to be involved in PMPs. For this reason, UbiPOL aims to provide ‘context aware knowledge’ provision with regards to policy making, i.e. through UbiPOL enabling citizens in identifying any relevant policies along with other citizens’ opinion ‘whenever they want’ ‘wherever they are’ according to their everyday life pattern. As a result of this platform, citizens are anticipated to be more acquainted with the newest relevant policies and PMPs for their participation during their routine life activities. Moreover, this platform is also anticipated to provide policy tracking functionality through a ‘workflow engine’ and ‘opinion tag’ concept to improve the transparency of PMPs. As a final point, the platform intends to facilitate policy makers to collect citizen opinions more efficiently as the opinions are collected as soon as they are created in the middle of citizen’s everyday life. UbiPOL provides security and identity management facility to ensure only authorised citizens can have access to relevant policies according to their roles in PMPs. The delivery of the opinion and policy data over the wireless network is secure as the platform use leading edge encryption algorithm in its communication kernels. UbiPOL is a scalable platform ensuring at least 100,000 citizens can use the system at the same time (e.g., for e-Voting applications) through its well proven automatic load balancing mechanisms. The privacy ensuring opinion mining engine prevents unwanted revealing of citizen identities and the mining engine prevents any unrelated commercial advertisements are included in the opinion base to minimise the misuse of the system.

<em>Abstract</em>.—In 1990, the U.S. Congress authorized the Army Corps of Engineers to study barriers to prevent the downstream movement of round gobies <em>Apollonia </em>(formerly <em>Neogobius</em>) <em>melanostomus </em>and other harmful, invasive fishes from southern Lake Michigan through the Chicago canal system into the Illinois River (a tributary of the Mississippi River). A demonstration electric barrier was activated too late (April 18, 2002) to block the gobies, but it was the only barrier to upstream movement of Asian carps from the Illinois River to Lake Michigan and provided useful information for design of a second, improved barrier (Barrier 2). We surgically implanted combined radio-and-acoustic transmitters in 130 common carp <em>Cyprinus carpio </em>that we released 20 m downstream of the demonstration barrier in the Chicago Sanitary and Ship Canal to assess the ability of the barrier to prevent upstream passage of fish. Movements of these fish were monitored from April 2002 through December 2006, within and beyond the 8.7-km reach bounded upstream by the electric barrier and downstream by the Lockport Dam and Lock. Fixed hydrophones and radio antennas continuously monitored the canal immediately upstream and downstream of the barrier for signals from the transmitters. In addition, 32 surveys were conducted with boat-mounted receivers to locate transmitters that were out of range of the fixed receivers. The fixed receivers detected 109 of the 130 transmitters; most detections occurred within a few days after release of the fish. The tracking boat located 120 of the transmitters at least once and 100 at least twice. Most of the transmitters remained well downstream of the barrier and upstream of the lock, but one moved downstream beyond the lock, one passed upstream through the barrier, four moved upstream within 60–400 m of the barrier after moving downstream, and three remained at the release point for their entire battery life, indicating that the fish had died or the transmitters had been expelled. On two occasions, common carp were visually observed within half a meter of the surface (the limit of visibility) at the barrier. These fish were not observed to move beyond the downstream margin of the electric field. The traverse of the barrier on April 3, 2003 occurred at the same time as a tow was passing. A tow consists of steel barges that are lashed together and pushed by a diesel-powered boat. The tow may have facilitated the passage of the fish, either by entraining the fish or by distorting the electric field. The tracking boat detected the transmitter upstream of the barrier on April 10, 2003. The transmitter did not move more than 100 m during the remaining life of the transmitter, indicating that the fish was probably dead. After we reported the passage, Smith-Root, Inc. (operators of the electric barrier, under contract to the U.S. Army Corps of Engineers) increased the duty cycle of the electric field by fivefold. We did not detect any further passages of transmitters, suggesting that the existing electric field (Barrier 1) prevented upstream movement of adult common carp and that the new, improved barrier, in combination with Barrier 1, may be effective against the more recently introduced Asian carps.

<em>Abstract</em>.—In 1990, the U.S. Congress authorized the Army Corps of Engineers to study barriers to prevent the downstream movement of round gobies <em>Apollonia </em>(formerly <em>Neogobius</em>) <em>melanostomus </em>and other harmful, invasive fishes from southern Lake Michigan through the Chicago canal system into the Illinois River (a tributary of the Mississippi River). A demonstration electric barrier was activated too late (April 18, 2002) to block the gobies, but it was the only barrier to upstream movement of Asian carps from the Illinois River to Lake Michigan and provided useful information for design of a second, improved barrier (Barrier 2). We surgically implanted combined radio-and-acoustic transmitters in 130 common carp <em>Cyprinus carpio </em>that we released 20 m downstream of the demonstration barrier in the Chicago Sanitary and Ship Canal to assess the ability of the barrier to prevent upstream passage of fish. Movements of these fish were monitored from April 2002 through December 2006, within and beyond the 8.7-km reach bounded upstream by the electric barrier and downstream by the Lockport Dam and Lock. Fixed hydrophones and radio antennas continuously monitored the canal immediately upstream and downstream of the barrier for signals from the transmitters. In addition, 32 surveys were conducted with boat-mounted receivers to locate transmitters that were out of range of the fixed receivers. The fixed receivers detected 109 of the 130 transmitters; most detections occurred within a few days after release of the fish. The tracking boat located 120 of the transmitters at least once and 100 at least twice. Most of the transmitters remained well downstream of the barrier and upstream of the lock, but one moved downstream beyond the lock, one passed upstream through the barrier, four moved upstream within 60–400 m of the barrier after moving downstream, and three remained at the release point for their entire battery life, indicating that the fish had died or the transmitters had been expelled. On two occasions, common carp were visually observed within half a meter of the surface (the limit of visibility) at the barrier. These fish were not observed to move beyond the downstream margin of the electric field. The traverse of the barrier on April 3, 2003 occurred at the same time as a tow was passing. A tow consists of steel barges that are lashed together and pushed by a diesel-powered boat. The tow may have facilitated the passage of the fish, either by entraining the fish or by distorting the electric field.

Abstract There exist concerns regarding the failures that occur during the installation of thin cylinder-liners of engines at the authorized and unauthorized service centers. Analyzing the probable causes from the points of view of the design, manufacturing, and authorized and unauthorized installation procedures define the problem. The problem involves the simulation of the process of press-fitting the liner into the cylinder bore. A choice of finite element analysis using commercially available software ANSYS helped the analysis of the probable causes of failure. Estimation of the probable loads experienced by the cylinder-liners during the procedures that exist in the installation-process paved the way to the definition of loads that prevail in the problem of relevance. Prediction of the nature of contacts that prevail in the current problem and the impact of the application of the loads enabled the definition of constraints for the simulation procedures. Reference material properties chosen in the conservative sense modeled the problem realistically. The evolution of the recommendations for the manufacturing and installation of thin cylinder-liners concluded the study.

Full textAbstract:
Pipeline crossings of sensitive, state or federally-regulated resources are occasionally unavoidable and can substantially increase project costs and negatively affect project timelines. During due-diligence surveys for invasive plants, field botanists identified an undocumented calcareous fen and associated state-listed wetland plants along the route of Enbridge’s LSr and Alberta Clipper pipelines in northwest Minnesota. Calcareous fens are rare peat-accumulating wetlands dominated by groundwater discharge, a high mineral content, and are protected by state law. Their hydrology and chemistry provide an environment for a suite of state-listed plants that are specifically adapted and unique to calcareous fens. By state statute, calcareous fens may not be filled, drained, or otherwise degraded by any activity unless the Commissioner of the Minnesota Department of Natural Resources (DNR) authorizes the activity under an approved Fen Management Plan. The proposed LSr and Alberta Clipper Pipeline route in the area was collocated with existing Enbridge pipelines installed before the fen was identified. State regulatory staff quickly officially recognized the Gully 30 Calcareous Fen which initiated a lengthy permitting process to authorize Enbridge to construct the LSr and Alberta Clipper Pipelines through the Gully 30 Calcareous Fen. Avoiding the fen would have involved an impracticable reroute along several miles of greenfield. The state (DNR) and federal (Army Corps of Engineers) process involved detailed characterization of the resource, development and approval of an alternatives analysis according to Section 404(b)(1) guidelines, and drafting and approval of a project-specific Fen Management Plan which stipulated specific construction mitigation procedures including winter construction and protective temporary drainage, and post construction monitoring requirements. This presentation introduces the calcareous fen resource and examines the permitting and iterative, comment-response construction-design process as an example of successful collaboration between state and federal agencies and Enbridge to construct a pipeline through a highly regulated, sensitive natural resource while maintaining schedule.

Section 388 of the Energy Policy Act of 2005 (EPAct) amended the Outer Continental Shelf Lands Act (OCSLA) to grant the U.S. Department of the Interior (USDOI) discretionary authority to issue leases, easements, or rights-of-way for activities on the Outer Continental Shelf (OCS) that produce or support production, transportation, or transmission of energy from sources other than oil and gas, except for where activities are already otherwise authorized in other applicable law (e.g., the Deepwater Port Act of 1974 (33 U.S.C. 1501 et seq.), the Ocean Thermal Energy Conversion Act of 1980 (42 U.S.C. 9101 et seq.)) [1]. This authority was delegated to the Minerals Management Service (MMS), which was charged with developing regulations intended to encourage orderly, safe, and environmentally responsible development of alternative energy resources and alternate use of facilities on the OCS. MMS published its Alternative Energy/Alternate Use proposed rule in the Federal Register in July 2008 for public comment and held a series of public workshops to discuss the proposed regulations. The final regulations were submitted to the U.S. Office of Management and Budget (USOMB) on November 3, 2008 for clearance. In advance of final regulations, MMS announced an interim policy in November 2007 to authorize offshore data collection and technology testing activities in Federal waters. This measure was designed to allow developers to jumpstart data collection activities in support of potential future alternative energy development once regulations are in place. MMS has worked very closely with its State and Federal counterparts in implementing the interim policy, which has progressed most expeditiously on the Atlantic Coast. The interim policy is in effect until the MMS promulgates final rules. Beyond the MMS leasing process, several other Federal entities are involved in the permitting and licensing of alternative energy in the offshore environment, including the U.S. Army Corps of Engineers (USACE), the U.S. Coast Guard (USCG), and the Federal Aviation Administration (USFAA), among others. This paper will discuss the history of MMS’ program and policy development for offshore alternative energy activities; the steps taken to arrive at final regulations; as well as note the other regulatory bodies involved in the authorization of these activities in U.S. Federal waters.

Full textAbstract:
Three Way Catalysts (TWC) are extensively used for simultaneous control of three principal automotive pollutants, namely carbon monoxide (CO), Oxides of nitrogen (NOx), and hydrocarbon (HC). Most of works on three way catalytic converter have been carried out with noble metals such as Platinum, Rhodium, and Iridium have been tried individually and in different combinations and proportions. Noble metal catalysts give very good performance of reduction of (NOx), CO and HC in the narrow range of stoichiometric Air Fuel ratio. Noble metals are costly and not abundantly available. These draw backs of the noble metal catalysts have inspired to search for the alternative catalysts, which will perform well over the wide range of A/F ratio and are economical and abundantly available. This paper discusses the processing of ZSM-5 to Cu-Ion- Exchanged ZSM-5, ZSM-5 supported Cu-Pt bimetallic catalyst and Cu-Rh bimetallic catalyst and placing them in a three staged converter to study the reduction efficiencies of exhaust emissions CO, NOx, and HC in a 800 cc Maruti S. I. Engine. The experiments are carried out at 1500 rpm, 17.6 A/F ratio, different catalyst bed temperatures and different engine loads 0%, 17.5%, 35%, 52.5%, and 70% of full load. The results achieved are the maximum reduction of CO 90% at 375 °C NOx 90% at 375 °C and HC 61% at 380 °C. The same engine was also run for Noble metal converter (NMC) (EURO-II) purchased from an authorized Maruti distributor and the maximum reduction achieved were CO 89% at 375° C, NOx 91% at 375° C, and HC 70% at 390° C comparable to Zeolite Catalytic Converter (ZCC).

Full textAbstract:
Although the procedure for obtaining an American Society of Mechanical Engineers (ASME) Code Nuclear Certificate of Authorization has changed little since 1974, much of the process is not fully understood by designers and manufacturers of pressure equipment. It is the intent of this paper to make this process easier to understand and explain the key process steps in order to avoid unnecessary delays. The discussion will cover a number of topics including: “Contracting with an Authorized Inspection Agency,” “Deciding the Type of Certificate to Pursue. “Quality Assurance Program Preparation,” “Design Considerations,” “Preparing Welding and Non-Destructive Examination Documents,” “Training,” and “The Survey.” The requirements for obtaining one of the various ASME Certificates of Authorization are somewhat different for each. This paper focuses on an N-type Certificate and is intended to be a high level examination of the requirements and typical pitfalls in obtaining that certificate.

Full textAbstract:
There is a new large horsepower engine available in North America and supported by a well-established network of authorized factory dealers. The driver is based on a reciprocating engine design delivering 7670 to 8180 HP depending on site conditions. The 16-cylinder prime mover is specially engineered for gas transmission, storage and withdrawal service. Built on a diesel engine designed block, crankshaft, bearings, rods, and gear train, it provides long service intervals and 120,000 hours before major overhaul. Electronic ignition and combustion controls help conserve fuel, minimize emissions and keep the engine operating at peak capability under a variety of ambient and loading conditions. Electronic monitoring protects critical components and systems while greatly simplifying maintenance. The electronic control tightly regulates the combustion process, cylinder by cylinder, to optimize efficiency. It also controls the main cylinder and prechamber fuel delivery. Using sensor data based on ambient and turbocharged-aftercooled air intake temperatures, the microprocessors in the control system continuously monitor available engine power. With this information, the PLC controlling the compressor has the ability to load or unload the compressor to match the available engine output. Fuel efficiency is less than 5900 Btu/bhp-hr and NOx emissions of 0.50 grams/bhp-hr. The mechanical efficiency of the engine is greater than 43%. The mechanical refinements designed into the prime mover, are behind the high efficiency. For instance, the long stroke design maximizes fuel efficiency. A solenoid operated gas admission valve for each cylinder provides precise fuel metering. A calibration ring in the upper part of the cylinder liner helps reduce CO and NMHC emissions. Combustion gases do not collect in the gap between the piston and the liner wall, where most of these gases form. Instead, piston action forces them back into the combustion chamber for complete burning. In the event of a decline in fuel quality, a three-piece connecting rod enables a quick change in compression ratio without changing the piston. The paper will also cover details on maintenance intervals and costs, with additional features on the product along with construction details. Figure 1, illustrates a side view of the engine as Seen from the front.

Previous works of MAGNA in the field of thermal control systems was the thermal design, manufacturing and verification of the ROSETTA thermal Louvres [5]. Thermal Louvres in satellite applications are used for thermal control to avoid overheating of the new generation satellites by exposed or shadowed radiator area. The closing and opening of the louvers wings is performed by thermal controlled actuators. The Louvres system is designed to be controlled by solar radiation. The challenge in the project was the design, manufacturing and verification of louvers with less mass but higher efficiency than current louvers.

Full textAbstract:
With the introduction of GE’s latest and most efficient gas turbine, the LM6000 in 1992, and the end of production of GE’s LM5000 gas turbine in 1997, the concept of repowering aging LM5000 gas turbine powered cogeneration plants with LM6000 gas turbines was an idea that most LM5000 owners and operators dreamed about. The LM6000 is an ideal replacement for the LM5000 as they both have nearly the same mass flow and exhaust gas temperature (critical for Heat Recovery Steam Generator (HRSG) compatibility), are about the same physical weight and dimensions, and can be operated in the same power range. Also, as the LM6000 is a current production model, it has more readily available spare gas turbines and turbine parts, has a much improved heat rate, lower emissions level, and has an option (SPRINT), for added power. In December 1999, the UAE Oildale Energy Facility became the first plant to operate with a newly installed LM6000 in its former LM5000 package. (This March the second LM5000 to LM6000 repowering was completed for Calpine Corporation at their Greenleaf #1 Cogeneration Plant in Yuba City, CA.) Energy Services, Inc., GE’s authorized LM6000 repowering OEM, designed, engineered and project managed the repowering. This paper will present the reasons UAE decided to repower; discuss the technical challenges encountered with, and modifications made to, the GEC ELM-150 cogeneration plant to accommodate the LM6000; review the schedule; and provide the economic benefits of the improved heat rate and reliability of the LM6000.

Full textAbstract:
The U.S. Nuclear Regulatory Commission (NRC) staff issued Revision 2 to NUREG-1482, “Guidelines for Inservice Testing at Nuclear Power Plant,” to assist the nuclear power plant licensees in establishing a basic understanding of the regulatory basis for pump and valve inservice testing (IST) programs and dynamic restraints (snubbers) inservice examination and testing programs. Since the Revision 1 issuance of NUREG-1482, certain tests and measurements required by earlier editions and addenda of the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code) have been clarified, updated, revised or eliminated. The revision to NUREG-1482 incorporates and addresses those changes, and includes the IST programs guidelines related to new reactors. The revised guidance incorporates lessons learned and experience gained since the last issue. This paper provides an overview of the contents of the NUREG-1482 and those changes and discusses how they affect NRC guidance on implementing pump and valve inservice testing (IST) programs. For the first time, this revision added dynamic restraint (snubber) inservice examination and testing program guidelines along with pump and valve IST programs. This paper highlights important changes to NUREG-1482, but is not intended to provide a complete record of all changes to the document. The NRC intends to continue to develop and improve its guidance on IST methods through active participation in the ASME OM Code consensus process, interactions with various technical organizations, user groups, and through periodic updates of NRC-published guidance and issuance of generic communications as the need arises. Revision 2 to NUREG-1482 incorporates regulatory guidance applicable to the 2004 Edition including 2005 and 2006 Addenda to the ASME OM Code. Revision 0 and Revision 1 to NUREG-1482 are still valid and may continue to be used by those licensees who have not been required to update their IST program to the 2004 Edition including the 2005 and 2006 Addenda (or later Edition) of the ASME OM Code. The guidance provided in many sections herein may be used for requesting relief from or alternatives to ASME OM Code requirements. However, licensees may also request relief or authorization of an alternative that is not in conformance with the guidance. In evaluating such requested relief or alternatives, the NRC uses the guidelines/recommendations of the NUREG, where applicable. The guidelines and recommendations provided in this NUREG and its Appendix A do not supersede the regulatory requirements specified in Title 10 of the Code of Federal Regulations (10 CFR) 10 CFR 50.55a, “Codes and standards”. Further, this NUREG does not authorize the use of alternatives to, grant relief from, the ASME OM Code requirements for inservice testing of pumps and valves, or inservice examination and testing of dynamic restraints (snubbers), incorporated by reference in 10 CFR 50.55a.

Full textAbstract:
A rulemaking issued by the Department of Transportation (DOT) revises Hazardous Materials Regulations (HMR) to replace the hydrostatic pressure test with appropriate nondestructive evaluation (NDE) methods. The rule change is contained in Federal Register 49 Code of Federal Regulations (CFR) Part 180.509, “Requirements for inspection and test of specification tank cars,” paragraph (e) “Structural integrity inspection tests” [1]. The CFR authorizes liquid penetrant (PT), magnetic particle (MT), radiography (RT), ultrasonic (UT), and optically aided visual testing (VT) as allowable NDE methods for structural integrity inspections and tests. Other NDE methods may be allowed under special exemption issued by the Federal Railroad Administration (FRA) Office of Safety. Also included under the requirements of 49 CFR Part 179.7 is the need to qualify not only NDE personnel, but the procedures used to perform NDE reliably. In order to be effective, federal regulations require that the NDE methods have a proven sensitivity and reliability for finding the type and size of flaws likely to cause a tank car failure. In the early 1970s, an internationally accepted quantitative approach that assesses the probability of detection (POD) was developed for the National Aeronautics and Space Association (NASA) and was published in NASA CR-2369, February 1974 [2]. Transportation Technology Center, Inc. (TTCI), under contract with the FRA, and along with industry participation, uses the NASA approach to determine the POD for various NDE methods used in the inspection of railroad tank car circumferential butt welds (girth seam welds), fillet welds, and leak test samples. The emergence of a damage tolerance approach to determine inspection intervals for an engineered structure — in this case a railroad tank car — requires the quantification of the detectable flaw size for the NDE methods used during inspection. Damage tolerance techniques have initiated an evolution in NDE understanding, methods, and requirements. National Transportation Safety Board safety recommendations R-92-21 through R-92-24 address the suggested process of performing reliable inspection of railroad tank cars based on a damage tolerance approach [3]. NDE quantification using the POD approach is a key measure of NDE effectiveness and is integral to damage tolerance requirements. TTCI, working with the FRA, Railroad Tank Car Industry and D&W Enterprises (A NDE consulting company providing expertise in the area of NDE POD), has developed baseline POD curves for the allowed NDE methods. Initial evaluations were performed on the inspection of tank car circumferential butt welds. Subsequent efforts focused on butt welds, longitudinal fillet welds and leak test samples requiring inspection under the CFR. This paper reports quantitative results obtained during this research effort that address system safety and risk analysis during handling and transportation of railroad tank cars carrying hazardous materials.
