The following gaps in critical goals are derived through a direct comparison of the Needs to Goals transformation versus the current waste heat recovery solutions and their stated goals. 1. Critical: Implementation of a sustainable financial plan which can help to initiate an increase in waste heat recovery 2. Critical: Deployment of waste heat recovery strategies for reducing greenhouse emissions A proposed solution to achieve these two goals would be: 1. Purchasing waste heat from industries. 2. Storing this energy with our proprietary thermal storage materials. 3. Selling the stored energy at either industrial sites or to pricier markets. New thermal-storage materials and a mini-sized combined heat and power (CHP) system have been further developed. This system will be the first to involve the arbitrage of waste heat energy by using cheap thermal storage material (made with zero greenhouse emissions) and a mini generator. This system could play an important role in providing economic incentives for industries that wish to recover waste heat.

Повний текст джерелаDen här examensuppsatsen granskar olika metoder för att utvärdera ett larmsystem med inriktning mot trafiksäkerhet. Störande larm kan skapa stora mängder larm som försvårar arbetet för larmoperatörer. Vi föreslår två metoder för att avlägsna störande larm, så att uppmärksamhet kan riktas mot varningar med högre prioritet. En parallell korrelationsanalys som demonstrerade hög korrelation mellan både enskilda och kluster av larm. Detta presenterar ett starkt orsakssamband. En korskorrelation utfördes även, men denna kunde inte fastställa existens av s.k. följdlarm. För att assistera Trafikverket med schemaläggning av underhåll har en long short-term memory (LSTM) modell implementerats för att förutspå univariata tidsserier av diskretiserade larmsekvenser. Utförda experiment sammanfattar att LSTM modellen presterar bättre för larmsekvenser med återkommande mönster. För mera slumpmässigt genererade larmsekvenser, presterar modellen med lägre precision.

In the thesis the analysis of the results of theoretical and experimental studies of the turning process with the ability to control the dynamics of the system is carried out. The technique for studying the oscillation of the tool and the spindle during turning process is proposed. The methods of reducing the amplitudes of oscillations of the working parts of the lathes during the milling process, as well as on the basis of the CNC turning center, have developed an experimental stand equipped with a modulator and primary spindle speed sensors to study the influence of the eigen frequencies and forms of oscillation of the machine tool on the roughness of the surface of the part.

This thesis asks one basic question: how do "vertical" disease- or intervention-focused global health programs impact the underlying health systems of the nations they serve? Vertical programs-health aid focused on a particular disease, such as HIV, or type of intervention, such as immunization-receive the lion's share of global health aid dollars, and yet we know uncomfortably little about their long-run impact on broader health systems. Many speculate that vertical aid undermines health worker effectiveness, distorts national policies, and disrupts the supply chain for drugs and medical products. Unfortunately, a lack of hard data makes quantitative analysis extremely difficult. Using the tools of system dynamics, this thesis consolidates the collective wisdom of previously published investigations and anecdotal observations to reveal the field's prevailing "mental model" of the dynamic in question. The result is a set of diagrams that describe the known impacts of vertical programs on health systems, and also reveal dynamic effects not yet explicitly identified in the literature. These effects fall into four sub-systems of impact: care delivery specialization and fragmentation, care delivery development and mediocritization, health policy development and mismatch, and market development and distortion. These models are then used to better understand the effects of recent contextual developments-the HIV/AIDS epidemic and the emergence of large Global Health Initiatives.
(cont.) Through expert interviews, this thesis identifies the most pressing system stresses in this contemporary context: the commitment to chronic care delivery which HIV/AIDS intervention creates, and the critical need for harmonization between donors which this commitment reveals. Using case examples from Kenya, these dynamics are shown to be active today, and to have instigated mitigation strategies by practitioners in the field. Finally, the systems identified above bring into focus key leverage points, including donor coordination, health worker augmentation, and engagement of local markets, which can "tip" the impact of vertical programs from harming health systems to strengthening them. In doing so, this thesis provides guidance to policymakers and program implementers who seek to use their resources to strengthen systems and eventually obviate health aid entirely.

Повний текст джерелаThe aim of this dissertation is to systematically develop a continuative concept of driver-automobile cooperation, to evaluate its suitability on the basis of empirical data, and to value its provable potential in relation to existing approaches.Assumptions and premises regarding the human-machine interaction constitute the starting point of this work. The decisive altercation and notional differentiation of cooperation are explained in just this context, leading logically to a definitional demarcation of existing approaches, the demand of a specific role understanding of the interaction as well as the derivation of conceptual basic conditions. The structural and procedural characteristics of this specific interaction are then elaborated upon and used to identify the general attributes of cooperation between driver and automobile. In the following, such indicators are derived by which the implied profit as a result of cooperation between driver and automobile can be controlled and valued. Within the framework of several preliminary investigations, those driving situations were identified that would profit most from a cooperative interaction between driver and automobile. As a result, the two driving scenarios "Overtaking on Highways" and "Turning Left on Urban and Country Roads with Oncoming Traffic" were utilized in the experiments. Both single scenarios have been compared in independent experiments with regard to alternative system variants. The prove of specific hypotheses was embedded in the prototypical surroundings of a driving simulator. Finally, the possibility of establishing and embedding this interaction concept into the overall socio-technical context will be presented, and future perspectives will be discussed.

Повний текст джерелаIn this thesis, we are interested in the local analysis of singularly-perturbed linear differential systems and completely integrable Pfaffian systems in several variables. Such systems have a vast literature and arise profoundly in applications. However, their symbolic resolution is still open to investigation. Our approaches rely on the state of art of formal reduction of singular linear systems of ordinary differential equations (ODS) over univariate fields. In the case of singularly-perturbed linear differential systems, the complications arise mainly from the phenomenon of turning points. We extend notions introduced for the treatment of ODS to such systems and generalize corresponding algorithms to construct formal solutions in a neighborhood of a singularity. The underlying components of the formal reduction proposed are stand-alone algorithms as well and serve different purposes (e.g. rank reduction, classification of singularities, computing restraining index). In the case of Pfaffian systems, the complications arise from the interdependence of the multiple components which constitute the former and the multivariate nature of the field within which reduction occurs. However, we show that the formal invariants of such systems can be retrieved from an associated ODS, which limits computations to univariate fields. Furthermore, we complement our work with a rank reduction algorithm and discuss the obstacles encountered. The techniques developed herein paves the way for further generalizations of algorithms available for univariate differential systems to bivariate and multivariate ones, for different types of systems of functional equations

The intelligent precision turning system was developed in this research for the cutting force of the tool between the variation of feed rate and the spindle speed. The tool always wears, so the life of tool is shortened and the roughness of the surface is decreased because of the high speed cutting for generating a greater cutting force. If the cutting force is lower, the working time would become longer when the workpiece was manufactured in the turning system. In order to extend the life of tools and to consider the efficiency of working, while the cutting process was changed by regulating the feed rate which employed the servomotor driven in the turning system for generating the constant cutting force. The mathematical model of the cutting force in the precision turning system was derived. The PID controller, fuzzy controller and SOFC (self-organization fuzzy controller) were employed to control the feed rate in the system, respectively. The optimal cutting parameters were investigated and the different controllers' were also performed to study control performances from the individually experimental result.

The purpose of this research is to establish a useful model of tire''s cornering force of the motorcycle for the design of anti-skid braking control. The model takes into account the dynamics of the motorcycle, the dynamics of the wheel, the dynamics of the hydraulic control system, and the dynamics of the brake mechanism. A fuzzy controller, to control the slip ratio at a desired value 0.2 and to maintain maneuvering capability, is designed to inspect the validation of the model via simulation. Motorcycle''s cornering force value delivered from dynamic is comparative with tire''s cornering force value delivered from tire''s slip angle. It can decide that anti-skid braking system for motorcycle''s turning is good or not.

Computer-aided manufacturing (CAM) has replaced the handwritten NC code gradually. The CAM software calculates to produce tool paths, and directly simulates on the computer. This software helps to manufacture complicated yet precise components. When an engineer operates the CAM system depending on his experience and subjective ideas to decide the cutting strategy, this situation could reflect some difficulties in standardization and management of manufacturing companies. In addition, manually designed operation steps maybe too complicated, leads to reduce the efficiency of tool path planning. Therefore, this study not only researched on how to simplify the operation steps and procedures but also reduced the operational threshold. This thesis uses Siemens NX with Visual Studio C# to configure the secondary development environment. This study also adopts the API library provided by Siemens NX to import NXOpen function language into Visual Studio C# for program edition. For the development of a CAM-integrated turning system, this includes some common machine operations, such as the rough turning of the object’s surface, outer- and inner diameter, the finish turning of outer- and inner diameter, and the grooving of the inner diameter of an object. This integrated system is triggered by a custom menu in NX. The dialog interface of the system is designed to be multi-paged with streamlined content. All operations and parameter settings are integrated in the main interface. The path data generated by NX are exported into NC code with a novel lathe post-processor, which established in this study. Then, this NC code is imported into Vericut software for cutting simulation. Ultimately, the parts are practically cut using a CNC lathe machine. The actual cutting results verify that the tool paths generated in this system is feasible and reasonable. This study simplified the CAM turning process by parameterize the input of operations and standardize the processing strategy, thus increased the efficiency of tool path planning, and reduced human errors and operational thresholds.

Traditional headlight system mostly rely on fixed light system to provide low beam, high beam, and fog light to illuminate front road. It doesn’t allow cars to project headlight onto road accurately when making turns or cruising up or down hills. In addition, drivers might forget to turn on the headlight when cruising through tunnels or driving on a dark raining day, or forget to switch from high beam to normal beam when pass an incoming car. these situation would all affect drivers’ safety. Many car headlight manufacturers are aggressively developing new generation of automobile headlights, which are known as AFS(Advanced Frontlight System), to improve the traditional headlight systems. To in crease the safeness of driving at night time, this research proposes a way to solve the problems mentioned above. This research discusses the conditions such as headlight turning on and off analysis of headlight angle and its control. Generally, when cars are accelerating or slowing down, the car movement will often affect the direction illumination, and then cause a great impact on driver’s view. To solve this problem, we use axis displacements to identify the angle between car body and the ground, and use this angle to calculate deviation of headlight angle. When cars are accelerating, we adjust the direction of headlight according to car speed and safe breaking distance. When cars cruise on hills, we recognize the current situation of the car by using sensors installed on both front and rear bumpers of the cars. When cars are coming into a turn, the relations among angles of front tire, car speed, and radius of turning are calculated based on cornering equations. then use radius of turning to calculate which direction headlight should be projecting. Then the direction which headlight should be projected is then calculated from turning radius.
