Abstract:

The purpose of this work was to study and carry out glass etching of monocrystalline silicon using the Bosch method, acquaintance with the conditions of aspect-independent etching. The Bosch process was conducted using sulfur hexafluorideSF6 and perfluorocyclobutaneC4F8on OxfordInstrumentsPlasmaPro®Estrelas100. It was found that in order to level the problems that arise, it is necessary to vary the temporal relations of etching and passivation stages.

Abstract:

Bosch and Zeuch method–based flowmeters use the pressure rise triggered by the injection event in a different way in order to characterize the injected flow-rate time history. These typologies of measurement are the most widely applied to evaluate the injection rate of fuel injection systems. The injection rate of a Common Rail electroinjector has been measured with both Bosch and Zeuch method–based flowmeters. The objective has been to perform a benchmark on these two different flow-rate measuring principles. A slight reduction in the rising slope of the injected flow-rate, an anomalous tail at the end of the injection and a time delay in the flow-rate trace have been observed in the case of the Bosch method measurement. A one-dimensional numerical model of the hydraulic circuit of the flowmeter based on the Bosch method has been developed and validated successfully. This model has then been applied to study the cause and effect relationships between the features of the flowmeter hydraulic circuit and the alteration in the measured injected flow-rate pattern. Design keys for the optimization of the Bosch-based flowmeters are provided, even though the investigation has definitely assessed the superior accuracy of Zeuch method–based flowmeters, at least for the examined working conditions.

Abstract:

In micro-machined micro-electromechanical systems (MEMS), refilled high-aspect-ratio trench structures are used for different applications. However, these trenches often show keyholes, which have an impact on the performance of the devices. In this paper, explanations are given on keyhole formation, and a method is presented for etching positively-tapered high-aspect ratio trenches with an optimised trench entrance to prevent keyhole formation. The trench etch is performed by a two-step Bosch-based process, in which the cycle time, platen power, and process pressure during the etch step of the Bosch cycle are studied to adjust the dimensions of the scallops and their location in the trench sidewall, which control the taper of the trench sidewall. It is demonstrated that the amount of chemical flux, being adjusted by the cycle time of the etch step in the Bosch cycle, relates the scallop height to the sidewall profile angle. The required positive tapering of 88° to 89° for a keyhole-free structure after a trench refill by low-pressure chemical vapour deposition is achieved by lowering the time of the etch step.

Abstract:

The research field of metasurfaces has attracted considerable attention in recent years due to its high potential to achieve flat, ultrathin optical devices of high performance. Metasurfaces, consisting of artificial patterns of subwavelength dimensions, often require fabrication techniques with high aspect ratios (HARs). Bosch and Cryogenic methods are the best etching candidates of industrial relevance towards the fabrication of these nanostructures. In this paper, we present the fabrication of Silicon (Si) metalenses by the UV-Nanoimprint Lithography method and cryogenic Deep Reactive Ion Etching (DRIE) process and compare the results with the same structures manufactured by Bosch DRIE both in terms of technological achievements and lens efficiencies. The Cryo- and Bosch-etched lenses attain efficiencies of around 39% at wavelength λ = 1.50 µm and λ = 1.45 µm against a theoretical level of around 61% (for Si pillars on a Si substrate), respectively, and process modifications are suggested towards raising the efficiencies further. Our results indicate that some sidewall surface roughness of the Bosch DRIE is acceptable in metalense fabrication, as even significant sidewall surface roughness in a non-optimized Bosch process yields reasonable efficiency levels.

Abstract:

This paper presents a detailed model of a Common Rail Diesel injector and its validation using injection rate measurement. A new method is described for injector nozzle flowrate determination using simulation and measurement tools. The injector model contains fluid dynamic, mechanic and electro-magnetic systems, describing all-important internal processes and also includes the injection rate meter model. Injection rate measurements were made using the W. Bosch method, based on recording the pressure traces in a length of fuel during injections. Comparing the results of the simulated injection rate meter, simulated injector orifice flow and injection rate measurements, the simulated and measured injection rates showed good conformity. In addition to this, the difference between nozzle flow rate and the measured flow rate is pointed out in different operating points, proving, that the results of a Bosch type injection rate measurements cannot be directly used for model validation. However, combining injector, injection rate meter simulation and measurement data, the accurate nozzle flow rate can be determined, and the model validated.

A tremendous amount of work has been done recently in the area of Object Oriented Design (OOD) methodology. Most often, texts and papers explaining these methodologies are centered around the explanation of some arcane graphical notation. One is led to believe that the key to understanding Object Orientedness in general will be found by understanding and applying this notation. An understanding of the essence of OOD is difficult to acquire in this manner due to the disproportionate amount of energy required to memorize the graphic symbology. The prospective designer is often left with an understanding of the symbols, but with no understanding of how to apply them to a real world large scale problem. This paper provides an explanation of the Object Oriented paradigm with an example application to telemetry measurements. Next this paper provides an explanation of the most popular graphic notation for Object Oriented Design, the Booch Notation. Finally, this paper shows an alternative graphic notation that can be effectively used in Object Oriented Design during the initial stages of design to help eliminate the learning curve associated with the more popular Object Oriented notations.

Dissertação de mestrado em Estudos de Gestão
O estudo aqui apresentado tem como objetivo sugerir melhorias ao processo de seleção da Bosch Car Multimedia (CM). Este estudo sobre o processo de seleção da Bosch CM torna-se importante nesta fase em que a organização se encontra num período de grande expansão. Desta feita, o Recrutamento e Seleção tornam-se relevantes na medida em que levarão a Gestão de Recursos Humanos a escolher os melhores colaboradores que intervirão e contribuirão para tal expansão. Tendo por base objetivo apresentado, foi utilizada uma metodologia qualitativa para levar a cabo a recolha da informação necessária ao cumprimento do objetivo. O trabalho de recolha de informação implicou a realização de 22 entrevistas aos intervenientes do processo de seleção da Bosch CM, assim como um grupo de foco aos colaboradores que passaram pelo processo de seleção da organização. A partir da análise da informação qualitativa recolhida foi possível perceber as perceções dos colaboradores sobre o processo de seleção no geral, e, mais especificamente, relativa aos métodos de seleção mais comumente utilizados pela Bosch CM. Através dos testemunhos descrevem-se os diferentes tipos de operacionalização do processo de seleção, quais os seus pontos positivos e negativos do ponto de vista dos participantes, as dificuldades que estes sentem e melhorias que os mesmos propõem. Foi ainda possível recolher testemunhos reais sobre os resultados a que os processos de seleção da organização têm levado. Com este trabalho foi então possível encetar uma proposta de melhora do processo de seleção da Bosch CM que contou com a participação dos seus colaboradores e que irá permitir à organização ajustar o processo aos perfis dos intervenientes, equacionar o modo de participação de cada interveniente no processo, redefinir aspetos importantes para o sucesso da seleção, entre outras.
This work has as an objective the suggestion of improvements to the selection process of Bosch Car Multimedia (CM). The study of the selection process at Bosch Car Multimedia becomes important in this phase where the organization is rapidly growing. Thus, Recruitment and Selection become relevant in the means that they will allow Human Resources Management to choose the best employees that will intervene and contribute to these expansions. With this underlying purpose, a qualitative methodology was used to carry out information gathering necessary to fulfil the objective. The information gathering process included the realization of 22 interviews on the participants of selection process of Bosch CM, as well as a focus group with employees that went through the organization’s selection process. From the qualitative information analysis it was possible to understand employees’ perception of the selection process in general, and more specifically, relative to the selection methods more commonly used by Bosch CM. According to the retrieved testimonies we can describe the different types of operations of the selection process, it’s negative and positive aspects from the participant’s perspective, the difficulties that arise and the improvements that were proposed. It was also possible to retrieve real testimonies regarding the results that the selection process has brought. This work allowed for the elaboration of a improvement proposal of Bosch CM’s selection process, that included the participation of it’s employees and will allow the organization to adjust the process to the participant’s profile, rethink the participation method of each intervenient, redefine important aspects of the selection process, amongst others.

Abstract:

The production of ammonia is facilitated by the nitrogen reduction reaction (NRR), where the inert di-nitrogen molecule is converted to ammonia. Along with being a major carrier of hydrogen, ammonia holds authority in the fertilizer realm. Therefore, it is inevitable to develop a viable and eco-friendly method of production that is cost-effective and resource-efficient. The primary challenge of nitrogen reduction is the cleavage of the particularly stable nitrogen bond. The most popular Haber-Bosch process for ammonia production, although efficient, is highly energy-intensive, and the need for maintaining exceptionally high temperature and pressure conditions is an environmental concern. As an alternative, the direct conversion of nitrogen has been carried out by photocatalysis and electrocatalysis. However, this strategy falls short of achieving superior conversion efficiencies. Consequently, it is conceivable that a fitting catalyst can be the solution for the difficulties associated with NRR. Over the years, several attempts have been made at formulating the best catalyst, including chromium oxynitride nanoparticles, niobium dioxide, various metal (Ru, Al, Rh, Ga) clusters, single-atom catalysts supported on different surfaces, and double atom catalysts. Recently, perovskites have emerged into the spotlight as excellent catalysts for NRR. In this chapter, we discuss the challenges faced by researchers to formulate righteous catalysts for the sustainable reduction of nitrogen by studying each of these types with a few examples. We also review the recent advancements in the experimental domain of NRR using different electrochemical cells.

Abstract:

The first approaches to object-oriented modeling appeared by the second half of the 1970s, but not much happened for more than a decade, so there were still barely more than a handful of modeling languages at the end of the 1980s. It was the early 1990s that witnessed an ever-growing market in competing object-oriented methods so that potential users found it increasingly difficult to identify any single method that suited their needs. This phenomenon came to be known as the “method wars.” Towards the end of 1994 two of the “big” players, Grady Booch and Jim Rumbaugh, decided to join forces by integrating their respective approaches, the Booch method and OMT (Object Modeling Technique). In late 1995, Ivar Jacobson became a member of this team merging in his OOSE method (Object-Oriented Software Engineering). The efforts of the “three amigos” aimed at overcoming unnecessary differences between the individual approaches and also improving each of them by creating a common, standardized modeling language that could serve as an industry standard. The result was the release of the Unified Modeling Language (UML), version 0.9, in June 1996. The UML partners, an industry consortium, performed further work on UML. This led to the versions 1.0 and 1.1 being introduced in 1997. The latter was adopted by the OMG (Object Management Group) in the same year. The current version is 1.5 (OMG, 2003) but a major upgrade to 2.0 is in preparation (Björkander & Kobryn, 2003).

Abstract:

The results of the research related to the selection and justification of the parameters of office space comfort zones and sensors for their control have been presented. The parameters that determine the comfort zone of the premises have been divided into two groups. The first group includes microclimate parameters (temperature, humidity, and air quality). The second group includes the parameters due to the equipment operation (radiation, lighting, dust, atmospheric pressure, noise). It has been shown that the level of comfort depends on the class of office space. For classes A and B, the microclimate parameters can be controlled and maintained by built-in air conditioning systems. However, the parameters of the second group require the development and implementation of specific engineering solutions. Class C, D, E office premises require the development and implementation of control systems, both for the microclimate parameters and the parameters due to the equipment operation. The paper presents a thorough analysis of standards and scientific publications on the object of research. Based on the results of the analysis, it has been concluded that existing publications, as a rule, provide mechanisms and tools for assessing individual parameters of the comfort zone and do not provide recommendations for their generalized (comprehensive) definition. Standards regulate either the normalized values of parameters or provide methods, principles, approaches to obtaining them. A three-step algorithm has been developed to define the parameters that determine the comfort zone of office premises. The peculiarity of this algorithm is that it allows simultaneously taking into account both the level of employee satisfaction with the comfort zone and the actual values of the parameters obtained using instrumental measurement methods. This approach allows finding a correlation between the results obtained by the questionnaire survey and by measuring and selecting the optimal parameter values of the office space comfort zone. To determine the configuration of the control system of office space comfort zone more than 50 sensors manufactured by different firms and companies have been analyzed. The selection and substantiation of sensors were carried out by the method of comparative analysis of their technical characteristics. According to the results of the analysis, seven sensors were selected. In particular, the SHT30 sensor manufactured by the Swiss company Sensirion was chosen to determine the temperature and humidity; for measuring air quality BME680 sensor from the German company Bosch was chosen; to determine the illuminance – a sensor type GY-302; for electric radiation – digital unipolar sensor A3144; for the dust parameter – the sensor of the Chinese company Waveshare; for noise level measurement – a sensor based on the MAX9814 amplifier manufactured by the American company Arduino and for atmospheric pressure – a BMP280 sensor. The research results should be used at the stage of control system development, both the microclimate parameters and the parameters due to the equipment operation. They are especially relevant for office premises of C, D, E classes, which have a lower level of comfort zone compared to classes A and B.

The smoothness is due to previous work laid out by Douady–Hubbard. Moreover, the proof here is based on elementary calculations on the pushforwards of specific quadratic differentials. This approach is a computational illustration of the power of the far more general transversality theory of A. Epstein, and is further inspired by the proof of Lau-Schleicher. The irreducibility is due to Bousch and Lau-Schleicher, but with a different method. Finally, the chapter uses elementary combinatorial properties of the kneading sequences instead of internal addresses.

Abstract:

In this paper, a batch of microfluidic-based reactors with integrated micropillars was fabricated on silicon wafer with standard optical lithography and deep reactive-ion etching (DRIE) technique. A Bosch process of DIRE was used to obtain ∼ 85 μm etching depth and undulating sidewall profiles on the surface of those micropillars. Such structures boost surface-area-to-volume-ratio as well as enhance heat and mass transfer coefficients. Platinum (Pt) nanoparticles (NPs) stabilized by poly-acrylate sodium in a water-ethonal-based suspension were deposited on the reactor surface using a surface-selective infiltration method. By introducing methanol vapor/air gas mixture into the reactors, stable catalytic combustion of methanol over Pt NPs starting from room temperature can be achieved.

Abstract:

The present work deals with the first researches into the real capabilities of an electronically controlled injector for common rail systems in realizing a proper shaping of the fuel rate with particular reference to its rising profile. Injectors equipped with standard and geometrically modified control valves have been investigated in detail by means of computer modeling and simulation. Experiments have been carried out in order to validate the feasibility of such a shaping and the injection rate meter based on the method proposed by Bosch was used. The main result of this work is a noteworthy dependence of the fuel rate on geometrical modifications in the piloting stage of the injector, since a certain difference in the slope of the first part of the fuel rate has been attained. The injector model has been finally used to investigate further geometrical modifications to be realized in order to achieve the desired fuel rate shaping.

Abstract:

Two-phase microchannel heat sink is promising in cooling high power electronics with dielectric fluids. Compared to water, dielectric fluids can assure system safety in case of working fluid leakage. However, two-phase heat transfer of these hydrofluorocarbon refrigerants is restricted by their relatively low thermal conductivities and low latent heats. Numerous nanoscale/submicron structures have been developed to enhance the single and two-phase heat transfer in microchannels; but these techniques usually require nanoparticle seeds in multi-step wet processes or nanolithography to integrate these nanostructures. Therefore, most of these techniques were time-consuming and costly. In this study, we present a plasma etching method using a modified Bosch process to create silicon tips with nanoscale scallops in microchannels. This is a rapid and cost-effective method to integrate large density of nucleation sites without involving nanolithography method or using nanoparticle seeds. Then, these silicon tip arrays were aligned with side walls of microchannels. As a result, flow boiling heat transfer of a dielectric refrigerant, HFE-7000, is substantially enhanced in a microchannel heat sink (five parallel channels: 10 mm L × 220 μm W × 250 μm H). Compared to plain-wall microchannels, the average junction temperature can be reduced up to 10 °C at a heat flux of 55 W/cm2 and the equivalent thermal resistance of microchannel heat sink is reduced up to 31% at a mass flux of 1018 kg/m2·s.

Abstract:

Measures exist to adjust tailpipe NOx emissions to assigned values, for example cooled exhaust gas recirculation (EGR) or a SCR catalyst in conjunction with urea. The situation is quite different with soot when use of a trap is not feasible for reasons of cost, space requirements and maintenance. Due to the highly complex soot formation and oxidation process, soot emissions can’t be targeted as easily as NOX. So how can soot be kept within the limits? In principle, soot can be controlled by allocating sufficient oxygen and establishing good mixing conditions with vaporized fuel. The most effective measures target the injection system, e.g. increasing injection pressure, applying multiple injections, optimizing nozzle geometry. To investigate the impact of very high injection pressure on soot, an advanced injection system with rail pressure capability up to 3000 bar and a Bosch injector was installed at the Large Engines Competence Center (LEC) in Graz. Full load and part load operating points at constant speed and in accordance with the propeller law were investigated at the test bed to quantify the impact of high injection pressure on soot emissions. Test runs were conducted with both SCR and EGR while varying injection timing and air-fuel ratios. Use of a statistical method, Design of Experiments (DOE), helped reduce the number of tests. Optical investigations of the spray and combustion were conducted. The goal was to obtain soot concentration history traces with the two color method in order to better understand how soot originates and to be able to calibrate 3D CFD FIRE spray models for use with injection pressures of up to 3000 bar. Very low soot emissions can be achieved using high pressure injection, even when EGR is applied. DOE results provide a clear picture of the relationships between the parameters and can be used to optimize set values for the whole speed and load range. A reliable spray break up model can be used in further 3D CFD simulation to investigate how to reduce soot emissions.

Abstract:

Qatar fertilizer company (QAFCO) is one of the world’s largest single site producer of ammonia and urea with production capacity of 12,900 metric tons per day. Currently, QAFCO faces major challenges in terms of water streams management that is generated from many processes such as wastewater from Harbor-Bosch process and brine solution from multi-stage flash (MSF) desalination process. To protect the environment; QAFCO has been making an effort to minimize the disposal of all types of water disposed into the sea. Here, this project proposes to develop a viable and economically effective process that can reach zero-liquid discharge (ZLD) of all processed water or wastewater from QAFCO facilities. The best method for ZLD is membrane distillation crystallization (MDC) hybrid process that concentrates and minimizes the volume of wastewater/brine streams to form solid through crystallizer. Membrane distillation (MD) is a thermally driven membrane process. It applies low-grade energy to create a thermal gradient across a microporous hydrophobic to vaporize water in the feed stream and condense the permeated vapor in the cold side. This research work aims to evaluate the performance of MDC for ZLD using commercial/fabricated electrospun nanofiber membrane (ENM) PVDF –base membranes at different type water streams. A general observation, higher water vapor flux and water recovery were exhibited at higher feed conductivity at 70°C. Moreover, the fabricated hydrophobic PVDF ENMs results confirmed the formation of nanofiber at the membrane surface using scanning electron microscopy (SEM). In addition, the water contact angle values of PVDF ENMs were greater than 100° and have stable mechanical and chemical properties. The ongoing research work will conduct a comparison between the optimum PVDF ENMs and the commercial MD membranes in terms of water recovery, salt rejection%, fouling/scaling, amount of collected solid and energy consumption at optimum operating conditions in MDC. In addition, it will perform a techno- economic feasibility assessment of the MDC hybrid process.

Abstract:

Abstract The mixing of fuel and air in the combustion chamber of an IC engine is crucial to emissions formation. Therefore, developing effective diagnostic techniques for measuring mixing is critical for progressing IC engines. Existing methodologies for the optical measurement of air-fuel mixing, including Rayleigh scattering and Laser Induced Fluorescence (LIF), have demonstrated various diagnostic-implementation challenges, high uncertainties under engine-relevant environments, and strong interferences from the liquid spray which prevents their use in near-spray measurements. This work presents the use of an alternative approach based on a laser-absorption/scattering technique called Ultraviolet-Visible Diffuse Back-Illumination (UV-Vis DBI) to quantify local equivalence ratio in a vaporizing diesel spray. Ultraviolet and visible light are generated using a ND:YAG pumped frequency-doubled tunable dye laser operating at 9.9 kHz. The simultaneous UV-Visible illumination is used to back-illuminate a vaporizing diesel spray, and the resulting extinction of each signal is recorded by a pair of high-speed cameras. Using an aromatic tracer (naphthalene, BP = 218 °C) in a base fuel of dodecane (BP = 215–217 °C), the UV illumination (280 nm) is absorbed along the illumination path through the spray, yielding a projected image of line-of-sight optical depth that is proportional to the path-average fuel vapor concentration in the vapor region of the spray. The visible illumination is chosen at a non-absorbing wavelength (560 nm), such that the light extinction is only due to liquid scattering, yielding a projected image of the liquid spray. A key advantage of the method is that the absorption coefficient of the selected tracer is relatively independent of temperature and pressure for 280-nm illumination, reducing measurement uncertainties at engine-relevant conditions. Measurements are also achievable in near-spray vapor regions since there is no mie-scattering interference from the liquid spray. The diagnostic is applied to measure the fuel-air mixing field of a diesel spray produced by a Bosch CRI3-20 ks1.5 single-orifice injector (90 μm diameter) similar to ECN Spray A. Measurements are conducted in a non-reacting high-pressure and temperature nitrogen environment using a constant-flow, optically-accessible spray chamber operating at 60 bar and 900 K. The results are evaluated against existing ECN mixing measurements based on Rayleigh scattering. The diagnostic yields centerline and radial mixture fraction measurements that match the ECN Rayleigh measurements within uncertainty bounds.
