Abstract:
With the recent development of ultra-high vacuum high resolution electron microscopes (UHV-HREM), electron microscopes have become valuable tools for surface studies. Techniques such as surface profile image, surface sensitive plane view, and reflection electron microscopy have been developed to take full advantage of the atomic resolution of HREM to study surface structures. However a complete surface study requires information on both the surface structure and surface chemistry. Therefore in order to turn an electron microscope into a real surface analytical tool, the challenge is to develop a microscopecompatible, surface sensitive tool for in-situ surface chemical analysis.

Abstract:
Abstract The objective of this research was to develop a sampling protocol for contaminated soils after a large radiological accident. One of the criteria for good sampling method is reproducibility and accuracy of large number of samples collected in short time. Members of the chemical laboratories of the Fire Rescue Service of the Czech Republic (FRS CR), which are included in Radiation Monitoring Network, tested four tools in different soil types. More than 100 samples were collected. Root auger and square soil sampler seem to be the best for reliable soil sampling. Modifications of the root auger decreased of relative error of sampling to 7.5%. The root auger is recommended as a first-choice sampling tool based on: (1) ease, (2) operator safety, (3) collection of a representative sample (4) applicability to most soil types and (5) enabling collection of depth-discrete samples.

Abstract:
Auger mining machine which is used in thin coal seam gets coal by drilling. Its drilling distance always is dozens of meters. Because of the long Drilling distance, the deflection of the drilling tool was produced by deviating force . In order to improve auger mining machine’s preventing deflection character and scope of application, the research on preventing deflection mechanism of auger mining machine combining theoretical analysis and experimental research was carried out on the basis of a simplified drilling tool structure. The studies we have performed showed that: increasing the drilling assembly bending rigidity or the drill pipe weight can prevent deflection; reducing the distance between the drilling stabilizer and drill is another method to reduce amount of deflection.

Abstract:
Collapsing and shrinkage of hole wall are two troubles to drilling of bored pile. In order to avoid such troubles, ultimate hole depth of bored pile was deduced with dry excavation technology. To hydraulic excavation technology, by the method of finite element numerical simulation and finite element strength reduction, excavation process of hole of bored pile are simulated in ADINA and ANSYS software, The influences of hole radius, hole depth, power of rotary drilling rig and pressure of auger boring tool on stability of hole wall are analyzed. The analysis indicate that the major problem of stability of hole wall of bored pile in seasonal frozen ground in the west of China is hole shrinkage. the deeper and bigger the hole are or the greater the pressure of auger boring tool is, the more serious the phenomenon of hole shrinkage is. Under other same conditions, to reduce pressure of auger boring tool less than to 35KPa, hole shrinkage can be reduced effectively.

Abstract:
Auger electrons emitted in nuclear decay offer a unique tool to treat cancer cells at the scale of a DNA molecule. Over the last forty years many aspects of this promising research goal have been explored, however it is still not in the phase of serious clinical trials. In this paper, we review the physical processes of Auger emission in nuclear decay and present a new model being developed to evaluate the energy spectrum of Auger electrons, and hence overcome the limitations of existing computations.

Abstract:
The parameters of drilling boreholes (including depth, diameter, angle of borehole inclination, cross-section) that are currently used for the making bored piles under the conditions of dense urban area, have been considered. The review about modern technologies of drilling boreholes used for making bored piles has been prepared. The updated classification of drilling technologies used for the making bored piles, which taking into account the nature of the removal of the destroyed rock and the movement of the drilling tool, the type of drilling tool, as well as the method of mounting the borehole walls, has been proposed. The classification, according to the nature of removal of the destroyed rock, distinguishes technologies providing or not providing the removal of destroyed rock. According to the nature of movement of the drilling tool, the rotary, shock and vibration technologies, as well as a static indentation technology, can be identified. According to the type of drilling tools, the classification divides methods into hollow drill stem with sacrificial drill bit and soil compactor and displacement tools with a starter auger section, augers, drilling buckets, core barrels, belling buckets, roller, impact and three-way bits, grabs. According to the methods of well casing, the technologies can be divided into the ones, allowing and not allowing the casing of well.

Abstract:
In this paper, fine-grain WC/Co tools were utilized in dry turning of the Ti-6Al-4V alloy. The wear modes of the cutting tools at different cutting speeds were analyzed. The diffusion behavior between the cutting tool and the workpiece was studied in detail based on the Auger electron spectroscopy (AES) depth profile technology. The diffusion wear mechanism was revealed. The results showed that the diffusion layer formed at the interface between the cutting tool and the adhering material. The diffusion ability of C was the strongest, followed by W, the weakest was Co in all the elements of the cutting tool. The chemical reactions took place close to the adhering material, forming the reaction layer. As a diffusion barrier, it was possible to limit the elements diffusion from the cutting tool to the adhering material, decrease the changes in the cutting tool composition and damages. The diffusion layer, which was weakened by diffusion, was worn off and taken away by the fast flowing chip during the cutting process, causing the diffusion wear characterized by a smooth crater formation on the tool surface.

Abstract:
The paper provides an overview of research on the working processes of screw working bodies of technological machines. It is noted that at present such important issues in the theory of auger working bodies as the required number of auger turns, the required position of the auger spiral in relation to the center, etc. have not been fully resolved, since the solution of these issues can provide an increased productivity of the tool. A structural and technological scheme of a forest fire machine with multifunctional modules is proposed, which consists of auger working bodies, which can be changed modularly with a screw metal thread for a brush, depending on the area and type of soil, the rotor of the thrower, with the ability to drive the cutters-throwers and auger working bodies both from the power take-off shaft of the tractor, and using a hydraulic motor, a guide casing. A mathematical model of an auger working body with a hydraulic drive has been compiled for removing the ground cover with forest litter when extinguishing forest fires with a ground gun, so that combustible materials do not fall into the fire zone together with the soil flow from the rotor-thrower. The working process of the hydraulic drive of the auger working bodies of a forest fire ground-sweeping machine is described by a system of differential equations, including the equations of translational and rotational movements of the auger working body and the equation of the flow rate of the working fluid. The problem of optimization of kinematic and dynamic parameters of auger working bodies of forest fire ground-sweeping machine is set

Abstract:
Low-pressure, low-producing natural gas wells commonly encounter liquid loading during production. Because of the decline in the reservoir pressure and the flow capacity, wells can fall below terminal velocity. Identifying and predicting the onset of liquid loading allows the operators to plan and prepare for combating the liquid loading hence saving valuable reserves and downtime. The present industrial applications of artificial lift, wellhead pressure reduction by compressor installation at the wellheads and reduction in tubing size are costly and often intermittent. The thesis examines the above aspects to generate a workflow for identifying and predicting the liquid loading conclusively and also assessing the application of Auger Tool and foam combination towards achieving a cost effective and more efficient solution for liquid unloading. In chapters I-IV, I describe the process of using production surveillance software of Halliburton Digital Consulting Services, named DSS (Dynamic Surveillance Software), to create a workflow of identifying the liquid loaded wells based on well data on daily basis for field personnel and engineers. This workflow also decides the most cost effective solution to handle it. Moreover, it can perform decline analysis to predict the conditions of liquid loading. In chapters V-VIII of the thesis, I describe the effort of handling the problem of liquid loading in a cost effective manner by introduction of an inexpensive Auger Tool in the bottomhole assembly and using WhiteMax surfactant soapstick from J&J Solutions. Four different combinations of well completion and fluid were tested for performance in respect to liquid hold up, pressure loss in the tubing, unloading efficiency and critical flow requirement. The test facilities and instruments, along with the operational methods, are discussed in chapter VI. Except for the reduction of the operational envelope with the inclusion of Auger Tool, the performance improved with the insertion of Auger Tool. The best combination of Auger and foam system could be a result of flow modification by the Auger Tool caused by reduced pressure loss and increase in drag coefficient and also by reduced density and surface tension of foam.

Abstract:
Abstract The identification of foreign material at metal-oxide interface or at the poly-substrate interface by means energy dispersive spectroscopy (EDS) is very difficult. Auger depth profiling can be used as an alternative method to cross-section EDS analysis for the identification of very thin layers of foreign material in semiconductor devices. This article presents a sample preparation method adapted from a planar transmission electron microscopy sample preparation method so that Auger depth profiling can be used as a practical tool for identifying very thin layers of foreign materials at interfaces buried deep within semiconductor devices. The discussion covers the advantages, applications, and the procedure for performing the analysis. The high degree of control provided by the method gives an analyst the ability to easily thin down material layers to less than 100nm of a target layer, thereby significantly reducing sample preparation time as well as analysis time on the Auger tool.

Abstract:
Abstract Soil drilling operation has become one of the most important interest to researchers due to its many applications in engineering systems. Auger drilling is one of the ideal methods in many applications such as pile foundation engineering, sampling test for geological sciences and space. However, the dominant factor in determination of drilling parameters is real drilling operations experience, which may cause transportation blocking of chips that leads to accidents. As a result, soil drilling process using auger drilling is studied to obtain the controlling parameters and to optimize these parameters to improve drilling performance which enables proper selection of machine for a required job. One of the main challenges that faces researchers during using of modelling techniques to define the soil drilling problem is the complex nonlinear behaviour of the drilled medium itself due to its discontinuity and heterogeneous formation. This paper presents two models that can be used to predict the total resistive forces which affect the auger during soil drilling operation. The first proposed model discusses the problem analytically in a way that depends on empirical data that can be collected from previous experience while the second model discusses the problem numerically with less depending on empirical experienced data. The analytical model is developed using Matlab® interface while the numerical model is developed using discrete element method via EDEM® software. A simplified auger drilling machine is built in the soil-tool interaction laboratory, Military Technical College to obtain experimental results that can be used to verify the presented models. Data acquisition measuring system is established to obtain experimental results using a Labview® program. This program enables displaying and recording the measured data collected mainly from transducers planted in the test rig. Both Analytical and numerical models results are compared to experimental values to aid in developing the presented parametric study that can be used to define the working parameters during drilling operations in different types of soils.

Abstract:
In design-by-analogy, inventors draw inspiration from natural and man-made systems to create new, often innovative engineering products. Though methods exist to aid concept generation through design-by-analogy, they are not built on fundamental knowledge of how inventors inherently use analogies. Such a foundation is critical for developing effective analogy-finding tools and methods. In this research, we pursue an empirical product study to guide the creation of a computational tool that presents relevant analogies based on designers’ objectives. Using an inductive approach, we studied 57 design-by-analogy products and their inspiring analogs to identify how analogies entered the design process. We developed classification schemes that characterize the analogies and their design contexts, which includes the inventors’ field of work and design objectives. Findings emerged from identifying patterns in the classification results. When comparing academic and commercial inventors, we found differences in how they use analogies to find new product functions or gain better performance. We gained insight into how knowledge-driven and problem-driven analogy usage cases differ. Most intriguingly, we found that products commonly borrow critical functions directly from analog systems, but we also discovered instances of critical function inversion, where the sense of the critical function is reversed between the analog and the product. For example, this occurred with the ECO-Auger Tidal Turbine (critical function: “Convert fluid flow into rotation”) which was inspired by screw conveyors (“Convert rotation into material flow”). This discovery implies that a computational search for analogs should expand from a designers’ function specification to include analogs with inverted critical functions, thus widening the space of possible inspiration sources.

Abstract Accurate characterization of the nitrogen concentration and distribution in ultra thin nitrided silicon gate oxide plays the same important role as the fabrication technology itself during the development of 90nm and beyond gate oxide manufacturing process. Based on the measurement results of XPS (X-ray photoelectron spectroscopy) as reference, a correlation study was taken between XPS and AES (Auger electron spectroscopy) data in this paper. The study shows that, by optimizing the experiment conditions of AES such as beam energy, beam current and take off angle, and introducing proper corrective factor, AES can be used as a useful and reliable characterization tool during the monitoring measurement of Nitrogen concentration in ultra thin (<2nm) nitrided silicon gate oxide.

Abstract:
Abstract Multiple parts failed during a 96 hour HAST (highly accelerated stress test) run. Electrical failure occurred on several pins stressed at 48V during the run. Visual inspection identified possible corrosion damage occurring on a top layer aluminum metal line linked to the failed pins. Additionally, significant lengths of this line and metallization at six other sites appeared white and reflective when viewed through an optical microscope. The device technology utilized a TiN ARC. Aluminum metal with a TiN ARC has a dull, amber color when viewed through an optical light microscope, as opposed to bare aluminum, which appears white and shiny. The initial assumption was that the passivation had lifted off during mold compound removal, along with the top TiN ARC layer at these seven locations. SEM inspection found that final passivation film was still intact over these shiny Al lines, but it was cracked extensively. Neighboring Al lines did not show cracked passivation. A hypothesis was generated that suggested that the TiN ARC was not removed, but rather was altered in some way so as to change its optical appearance. The change in the TiN was believed to be due to a combination of factors that resulted from electrical overstressing of the lines during HAST. A series of experiments utilizing FIB cross-sections, Auger mapping, Auger depth profiling, TEM inspection and EDS were used to show that the TiN ARC layer was still present on the affected lines but had been oxidized. The conclusions drawn from this investigation can be used to rapidly determine the root cause of failure through signature analysis. Shiny Al metal lines are easy to see with optical microscopes and are therefore a useful failure analysis tool to identify electrically and mechanically overstressed lines and circuits.

Abstract:
Abstract This paper discussed on how the importance of failure analysis to identify the root cause and mechanism that resulted in the MEMS failure. The defect seen was either directly on the MEMS caps or the CMOS integrated chip in wafer fabrication. Two case studies were highlighted in the discussion to demonstrate how the FA procedures that the analysts had adopted in order to narrow down to the defect site successfully on MEMS cap as well as on CMOS chip on MEMS package units. Besides the use of electrical fault isolation tool/technique such as TIVA for defect localization, a new physical deprocessing approach based on the cutting method was performed on the MEMS package unit in order to separate the MEMS from the Si Cap. This approach would definitely help to prevent the introduction of particles and artifacts during the PFA that could mislead the FA analyst into wrong data interpretation. Other FA tool such as SEM inspection to observe the physical defect and Auger analysis to identify the elements in the defect during the course of analysis were also documented in this paper.

Abstract:
Abstract X-ray photoelectron spectroscopy (XPS) is a very popular tool for identification of the chemical state of fluorine contamination on aluminum (Al) bond pads. To date, as far as the authors are aware the detailed microstructures of fluorine corrosion on bond pads have not been reported. This paper reports the microstructure evolution of fluorine corrosion on bond pads in a plastic box under specific environment conditions by using transmission electron microscopy (TEM), optical microscopy, focused ion beam and scanning electron microscopy (SEM). The elemental distributions and chemical bonding were performed by using Gatan Image Filter/TEM, energy dispersive X-ray/Scanning TEM (STEM), Auger electron spectroscopy and XPS, respectively. On Al pads with 35 atomic %, fluorine residual, corrosion was observed after around 10 days of storage and became more severe with time. The corrosion layers consist of nano-crystalline and amorphous for both single and double-layer structures.
