Abstract:
THE Criminal Justice and Public Order Act 1994, which attracted so much controversy during its passage, continued to provoke dissent in the first case to reach the House of Lords on the interpretation of its public order provisions. The question in Director of Public Prosecutions v. Jones [1999] 2 W.L.R. 625 was the extent of the public's right to use the highway and, more specifically, whether a public assembly may constitute a lawful user.

Abstract:
AbstractPuparia of house flies, Musca domestica L., and stable flies, Stomoxys calcitrans (L.) (Diptera: Muscidae), were collected on dairy farms in Prince Edward Island (PEI) and New Brunswick (NB) and held for emergence of hymenopterous parasitoids. Percent parasitism for PEI in 2003 and 2004 was 6.7 (n = 10 060 puparia) and 1.0 (n = 36 992 puparia), respectively. Percent parasitism for NB was not determined in 2003, but was 9.1% (n = 3052 puparia) in 2004. A parasitoid provisionally identified as Phygadeuon ?fumator Gravenhörst (Ichneumonidae) predominated in both provinces. Additional species recovered included Aphaereta pallipes (Say) (Braconidae) and Muscidifurax raptor Girault and Saunders, Spalangia cameroni Perkins (PEI only), Spalangianigra Latreille (NB only), Spalangia subpunctata Förster (NB only), Trichomalopsis americana (Gahan) (PEI only), and Urolepis rufipes (Ashmead) (Pteromalidae). Dissection of host puparia from which neither flies nor wasps emerged yielded a relatively large number of additional parasitoids, particularly S. nigra.

Abstract:
AbstractSince the 1990s, Canada's francophone minority communities (FMCs) have become increasingly involved in francophone immigration governance, and this trend has coincided with the wider neoliberalization of immigration in Canada. This article analyzes the implications of the growing influence of a neoliberal immigration policy and the narrative of an ideal immigrant on Canada's FMCs by focussing on the francophone Acadian community in New Brunswick, Canada's only constitutionally bilingual province. Making use of three types of sources—semistructured interviews, debates in the Legislative Assembly of New Brunswick, and official and archival documents—the article argues that francophone and Acadian organizations have adopted the federal, neoliberal perspective on immigration, placing greater emphasis on economic integration and the creation of a bilingual workforce. Changes in the type of immigrant selected and role of the community in the lives of francophone immigrants create new challenges for minority language communities that define and identify themselves through language use and belonging.

In Nepal, the twice-postponed elections for the Constituent Assembly were successfully held in April 2008. The Maoists, who obtained a plurality of seats, took office at the head of a multi-party coalition following the formal abolition of the monarchy. Yet, fundamental issues still remained unresolved, including integrating the guerilla forces into the national army. In Bhutan, elections for the lower house were won decisively by the party led by Jigme Thinley, and the country's new Constitution was promulgated.

Abstract The highly challenging activity of designing tires can be supported by different types of software. An IBM compatible PC based technical documentation system has been worked out to help with both the design and manufacturing of four belted truck tires. It has the capability for construction of tire section geometry, for processing of pattern and general assembly drawings, etc. From the basic geometrical information pre-processing can be done by using an interface module for an in-house finite element analysis program. Examples are shown how the belt construction has been modified for a given TOP type tire.

Abstract:
Purpose Micro ultra-thin tubes have important implications in aerospace, nuclear energy and other fields. In microassembly process, these parts are characterized by following reasons: the small size can easily lead to damage when gripping, even for low intensity and the parts are mainly affected by the instability of light source, for vision-based systems, the visual information about ultra-thin tubes is difficult to gather and the contact state is hard to monitor. Design/methodology/approach The paper presents a new method to adjust the position deviations based on contact forces during microassembly processes. Specific research is such that the assembly model was established based both on mechanic calculation and numerical simulation; the assembly task was carried out on an in-house microassembly system with coaxial alignment function (MSCA), the contact statements were controlled based on force sensor feedback signals and the model of the relationship between contact force and assembly deviations was established. Through a comparative study, the results of experiment and simulation differ by less than 11 per cent, validating the accuracy and feasibility of the method. Findings The model of assembly force and position deviations of micro ultra-thin tubes based on MSCA has been built. Besides, the assembly force threshold, and the assembly process parameters have been obtained. Originality/value The assembly process parameters obtained from experiments can be applied in the precision assembly and provide theoretical guidance and technical support to the precision assembly of the multi-scale parts.

In the era of knowledge-driven economy, knowledge management plays a relatively important role in the enterprise. The purpose for the enterprise to apply knowledge management is to help integrate, analyze and manage its information. Applying knowledge management will make the enterprise empower itself to be more competitive. Facing the short life cycle of its products the semiconductor assembly industry has to shorten its product development, that is, to achieve the 4T of the R&D of the new product—(1)Time to idea, (2)Time to product, (3)Time to market and (4)Time to Volume. To reach the above- mentioned goal the application of knowledge management is obviously of great urgency. Knowledge management is the backbone of this article. The characteristics of knowledge management, which includes the accumulation and the sharing of knowledge or technology, the handing down of experiences, the increase of assessing standards, the reduction of failure rates and so forth, makes the product engineers and the process engineers while in the course of the R&D of the new product have access to check the database to make use of and innovate in relevant technology, and even to apply for a patent as well as to avoid encroaching invented patent. This way the enterprise will develop its own product in time and successfully put it into mass production to not only meet the customer’s demand but also make its profit to reach a win-win situation.

Abstract:
Born in New Bern in 1758 to a prominent colonial official, Richard Dobbs Spaight rose quickly in North Carolina politics, becoming an aide-de-camp to Governor Richard Caswell in 1778. He later served as speaker of the lower house of the state assembly, as a member of Congress under the Articles of Confederation, and as governor. As a delegate to the federal Constitutional Convention, Spaight made one highly significant procedural motion: to permit a delegate to request reconsideration of a previously decided issue. A Federalist and a conservative, Spaight believed in the rule of elite, and in his mind, public-spirited slave-owners. In the late 1790s, however, he became a Democratic-Republican. A partisan feud led to his death in a duel with Federalist John Stanly in 1802.

Abstract:
The 1991–2015 period saw both the diminished importance of the traditional anti-system parties of the left (due to the end of Communist rule in Europe) as well as the rise of new populist radical right-wing parties. As a response to the sharp rise of tactical obstruction by loyal opposition parties, the French National Assembly became a hybrid legislature when committees were empowered under centralized agenda control in 2008. With no similar increase of obstruction in the British House of Commons, no substantial procedural reform occurred. In the two working legislatures (the Riksdag and the Bundestag), legislators maintained their preference for work. This explains the procedural path dependence in both legislatures despite the appearance of a potential anti-system party (the Sweden Democrats) in the Riksdag. Given the absence of sustained obstruction by the Sweden Democrats, followers successfully reversed an attempt to informally centralize agenda control in the Riksdag.

Abstract:
This chapter focuses on Scottish Atlantic literature from the 1660s to the early 1690s. It explores how colonial utopian writing broadened in the mid-seventeenth century to include drama, life writing, legal sources, and abolitionist texts, including not only literature directly linked to Atlantic expansion but also texts usually associated with domestic Scottish literature, such as Thomas Sydserf's Tarugo's Wiles: Or, the Coffee-House (1668) or Archibald Pitcairne's The Assembly; Or, Scotch Reformation (1691). Engaging with recent works on Scotland's role in Atlantic slavery and the Black Atlantic, the chapter seeks to broaden understandings of how Scottish literature and culture participated in the development of the Black Atlantic and Eurocentric thought. The chapter further looks at legal and governmental sources relating to New Jersey and the Middle Colonies from the 1680s onwards, at abolitionist writings, and texts that pertain to the Six Nations and indigenous populations of the Americas. All of these bring out the paradoxes of possession versus dispossession and of freedom versus enslavement in Scottish colonial literature. They illustrate how aesthetic devices of utopianism work towards spatializing the colonial sphere and trying to stabilize boundaries between colonizing and colonized subjects.

Abstract:
Driven by the green logistics, automated guided vehicle (AGV) has been widely accepted as a new transportation tool for in-house logistics, which enables a timely supply of parts to the designated workstations with less energy consumption. However, the existing scheduling methods for AGV scheduling are designed to minimize inventory or cost without explicitly considering energy saving. To fill the gap, this paper proposes an AGV scheduling model for energy saving in a mixed-model assembly line, where AGVs can have variable travel speeds. A mixed-integer model is constructed and an exact solution procedure is provided. Simulation studies are performed to investigate the main factors that determine the energy consumption and to demonstrate the effectiveness of the proposed method.

Full text
Abstract:
Failure analysis of integrated circuit (IC) packages is a critical element for in house quality control and for problems encountered in service. Plastic IC packages are routinely inspected for delaminations, voids, cracks, and corrosion using the C-mode acoustic microscopy (C-AM). Plastic IC packages are hygroscopic and can absorb moisture subjected to environmental cycling depending on the quality of the plastic chemical compound used to encapsulate the IC chip. The new advanced ultrasonic interference spectroscopy (UIS) technique used by the author elsewhere to detect presence of moisture in adhesively bonded joints is applied to the problems of the plastic IC packages in this research work. The new UIS technique was used on manually fabricated simulated plastic packages with thin water film trapped between two layers of plastic material (Lexan) and the silicon wafer. The technique successfully detected the presence of an extra water layer in the assembly inspected and estimated its thickness accurately to be 110 μm. At present the technique is under development for detection of water films thinner than 110 μm in actual plastic IC packages.

Abstract:
The control rod drop time is one of the most important parameters for safety analysis. The calculation accuracy of control rod drop time will be affected if ignoring the transverse vibration, which is mainly caused by the fluid-structure interaction between the RCCA (rod cluster control assembly)s, guide tubes and the fluid interaction. A new method for RCCA drop analysis is presented in this paper. The transverse equations of motion are established considering fluid-elastic structure interaction, assuming the fluid is incompressible laminar flow. And the vertical equations of motion are established considering the gravity force of RCCAs, the fluid resistance, and the friction force led by collision. A computer program based on this method is used to calculate the control rod drop time, the impact and the dynamic response of RCCA. The analysis results are compared with those of the in-house code, which is used for commercial design. It shows the computer program using the new models provides a useful tool in the design of RCCAs and fuel assemblies.

Abstract:
“Vertical type” spool configuration is commonly adopted as riser base spool for deepwater field development. With increasing water depths and risers subject to harsher environments, the excessive lower riser assembly motions and slugging induced fatigue damage have emerged as the governing design criteria for deepwater riser base spool design. Conventional vertical spool has inherent shortcomings to handle such design conditions. A new “hybrid” concept is therefore proposed, which extends beyond the “traditional” spool concept by integrating both vertical and horizontal spools into a 3D configuration. It inherits the vertical spool’s strength on handling large spatial expansion and utilise the pipe-soil interaction to dampen the potential resonance caused by slug flow. Several prototypes have been examined and the hybrid spool expansion-mechanism is discussed together with an optimisation procedure proposed. An advanced FEA technique using both Abaqus/Flexcom has been employed as part of the hybrid spool development, which consists of rigorous 3D dynamic analysis, bespoke non-linear soil interaction model and utilising the global riser dynamic behaviour. An in-house spool automation tool is developed to optimise the iterative analyses required to obtain a satisfactory hybrid spool configuration. This paper described a successful case study in recent deepwater hybrid riser bundle (multibore hybrid riser) tower development project, where the need to accommodate large lower riser assembly motion and slugging fatigue damage are the two main design drivers. This presentation provides a creative insight into this innovative technology.

Abstract:
Abstract Fluorine contamination on Al bondpads will result in corrosion, affect quality of bondpads and pose problem such as non-stick on pad (NSOP) during wire bonding at assembly process. In this paper, a fluorine contamination case in wafer fabrication will be studied. Some wafers were reported to have bondpad discoloration and bonding problem at the assembly house. SEM, EDX, TEM, AES and IC techniques were employed to identify the root cause of the failure. Failure analysis results showed that fluorine contamination had caused bondpad corrosion and thicker native aluminium oxide, which had resulted in discolored bondpads and NSOP. It was concluded that fluorine contamination was not due to wafer fab process, but was due to the wafer packaging foam material. XPS/ESCA and TOF-SIMS advanced tools were used to study the chemical and physical failure mechanism of fluorine-induced defects. An unknown Al compound was found using XPS technique and identified it as [AlF6]3- using electrochemical theories and TOF-SIMS technique. This finding was very significance, as it helped developing a theoretical electrochemical model for fluorine-induced corrosion and helped understanding of the mechanism of fluorine-induced corrosion on aluminium bondpads. It was found that fluorine contamination had formed [AlF6]3-on the affected bondpads and it had caused further electrochemical reactions and formed some new products of (NH4)+ and OH-. Then [AlF6]3- and (NH4)+ ions combined and formed a corrosive complex compound, (NH4)3(AlF6), while the OH- reacted with Al and caused further corrosion.

Abstract:
Abstract The Plug and Abandonment (P&A) requirement stipulates a permanent barrier to be placed for restoring the cap rock during well abandonment. For a single casing, section milling has been successfully implemented and widely used for a number of years. For a dual casing string, this becomes particularly challenging when both casing strings are cemented. Conventional techniques require milling the entire inner casing from the top of cement followed by section milling the outer casing. This could require milling up thousands of feet on of the inner string and is not a cost-efficient solution. The service company has been heavily involved in a number of P&A campaigns, where the requirement was to come up with a solution for dual casing section milling. This paper discusses the design, technology, field runs and best practices developed to overcome this operational and economic challenge and save rig time in P&A operations. The challenge was to design a robust section mill that can drift through the inner casing restriction and expand to a high ratio to mill the outer casing. It was equally critical to manage shock and vibrations during the milling operation, ensure stability and, competitive ROP without incurring tool damage. To solve the operational and economic challenges, a unique system was developed to reduce the rig time. The system is a combination of the newly engineered high-ratio hydraulic section mill, with a 180% expansion ratio and a precisely oriented hydraulic stabilizer below it. This creates a unique 6-point stabilization system that helps to maintain the dynamic loads and vibrations to a manageable level. The system allows for a dual casing section window in few trips as compared to conventional techniques. In the first run, a window in the inner casing is milled by a section mill. During the second run, the High-Expansion Ratio Section Mill (HRSM) is run through the restriction, and mill the entire casing. A high ratio under reamer can be included in the bottom hole assembly to clean the section and expose the formation prior to the cementing operation. This completes achieving a rock-to-rock barrier in a dual cemented casing application. The new HRSM system has so far been 100% successful on the five challenging jobs completed in Europe, Asia and the Middle East, resulted in significant rig-time savings along with the added benefits of fewer trips and less swarf at the surface. Two sizes have been developed and tested for 7"x9-5/8" and 9-5/8"x13-3/8" applications. The success during the early jobs is largely due to the robustness of the mill design, proper pre-job planning, meticulous execution, and implementation of key learnings from in-house and prior field tests.

Abstract:
Abstract The motivation for this work has been a variety of motions like navigation of pipelines, insertion operations in assembly, and gripping actions, which require the adaptation of the mechanism to the external constraints, rather than avoid them. To this effect, efforts have been made towards building mechanisms that obtain the required degrees of freedom through deformations rather than explicit joints in them. Although the use of many joints provides the required number of degrees of freedom, it does so at the cost of making the system very bulky and complex. With the advent of new polymers, the possibility of building such mechanisms without joints, that fulfil the requirements of adaptation, have increased. Based on this approach, a Magneto Active Polymer (MAP) material has been developed in-house at the Texas A&M University, in which the actuation is performed by the conversion of electromagnetic energy into mechanical energy. The initial experimentation has proved the vast potential of the use of such a material, and a few mechanisms, like a magneto active peristaltic pump, have already been developed and tested, using this material. In this mechanism the pumping action is obtained when a moving magnetic field produces peristaltic waves in the magneto active material shaped as a tube. These waves help in pushing the fluid forward, in the tube. The advantage of this mechanism is that there is not physical contact of the actuating mechanism an the MAP tube, thereby reducing the wear. In developing the design for the peristaltic pump and other conceptual models described in this paper, ideas have been drawn from the different modes of locomotion and actuators used, in lower organisms and these have been good sources of inspiration for the work detailed in this paper.

Abstract:
The supercritical closed Brayton cycle concept is widely recognized as an attractive new option for energy conversion because of the very high-efficiency, reachable at moderate turbine inlet temperature, and the very compact general assembly. Carbon dioxide is chosen as the working fluid because it allows for its compression to occur close to the critical point at suitable temperatures, and high pressure. Compression work is thus small, if compared for instance to air compression. The concept was first studied in the sixties, and recent interest spreading in the scientific and technical community led to the realization of a small-scale proof-of-concept prototype operating at Sandia’s National Laboratories. Moreover, the CSP SunShot project was recently funded by the U.S. National Renewable Energy Laboratory, and it is aimed at the realization of a multi-megawatt concentrating solar power plant, whereby the power block will be a supercritical CO2 Brayton cycle turbine. Other pre-commercial activities are ongoing. This paper focuses on the study of the fluid dynamics of turbomachinery operating with fluids characterized by a complex thermodynamic behavior. The goal is to develop a complete methodology to help the aerodynamic design of scaled-up turbomachinery for supercritical CO2 gas turbine power plants. Starting from a previous analysis of the impeller of the radial compressor of the Sandia proof-of-concept test bench, the new detailed computational domain includes the tip clearance and the vaned diffuser, and has been obtained using an in-house meshing tool suited for turbomachinery geometries. The steady state interface between the impeller and the diffuser is treated with a mixing-plane. In order to correctly calculate the thermophysical properties of the fluid, affected by strong variations close to the critical point, the solver is coupled with an extensive library for the computation of properties of pure fluids and mixtures. An accurate multiparameter equation of state is selected and a look-up table approach is used to speed up the fluid properties evaluation. The results are finally compared with experimental data, and demonstrate the potential of the tool.

Abstract:
The undisturbed geothermal gradient is a key thermal boundary that drives heat transfer processes occurring in oil and gas wells throughout their lifetime. However, the temperature distribution with depth is somewhat uncertain, and this is often assumed to be a linear approximation from the mudline to the bottom of the well. During drilling, the circulating temperature may significantly affect the rheology of the drilling fluids and the cement setting processes. Therefore, erroneous estimates of the wellbore temperature may affect the overall performance of the drilling phase and subsequent well operations. Further, it is important to know the accurate temperature distribution within the formation for assessment of the petroleum prospectivity through source rock maturation and reservoir quality. This paper presents a numerical methodology to estimate the undisturbed geothermal gradient while drilling in offshore wells. This methodology may also be applied to onshore wells by simplification. The new approach is based on an in-house axisymmetric wellbore transient thermal model, in which the equations are solved using the finite difference method. The model computes the heat transfer between the well and riser system with the surroundings. However, other computational codes may also be used following the framework presented in this study. The computer code should provide a detailed representation of the geometry of the wellbore, the physical properties of the drilling fluid and formation, the suitable thermal boundary conditions and temporal discretization. The temperatures of the fluid at the inlet of the drillstring and at the bottom hole assembly (BHA), in the annulus A, are used as input to the numerical model that iteratively adjusts the undisturbed geothermal gradient, which generated the temperature recordings while drilling. The paper comprises cases studies of hypothetical wells drilled in relevant offshore areas in the world, each with their distinctive and variable geothermal gradient, defined by the different rock formations encountered. Uncertainties regarding the thermal properties of the rock were also considered to ascertain the robustness of the code. The water depth of the drilling site was also observed to impact the convergence of the algorithm. The results obtained by the numerical approach are in good agreement with the expected values of the undisturbed formation temperatures. The novelty of the numerical framework is the ability to provide reliable and satisfactory estimates of the undisturbed geothermal gradient for wellbores with any configuration, lithology and rock properties. These estimates are based on temperature measurements of the circulating drilling fluid at the BHA and account for uncertainty in rock thermal properties; in reasonable time using standard engineering computers.
