Modern vehicles are more electrical than mechanical. As the vehicle industry goes on, more mechanical parts are being replaced by electrical components, e.g. x-by-wire. Weight and production costs could be the major factors in this revolution. To ensure the safety and in time response (meeting request’s deadline), the connection between these components is of great importance. Trying to find a protocol and standard that fits the vehicle industry to connect all ECUs, sensors and actuators together is not an easy task, since we are dealing with a system that has got a diverse type of traffic. Safety on the one hand and cost on the other hand are pushing the manufacturers to find the best networking protocol. In this report I am going to investigate the possibility and the risk of implementing on-board diagnostics over Ethernet. UDS (unified diagnostic services) and DoIP (diagnostic communication over Internet protocol) are the protocols that are going to be studied. To be more precise, I will investigate the possibility and the risk of UDS and DoIP implementation. The reason is that with the increasing number of ECUs and volume of data (parameter setting, downloading software, etc.,), the already implemented protocols and standards are not able to answer the required bandwidth. The wide acceptance and high bandwidth of Ethernet on one hand and its low cost infrastructure on the other hand has made Ethernet a candidate for this purpose.  The feasibility of Ethernet for in-vehicle network has already been investigated as I will show in the review of previous works. There are a couple of works that shows by using a suitable protocol in data link layer, we can meet the real-time requirement of a process. By reviewing these previous works we will find out that using Ethernet for vehicle on-board diagnostics is feasible. After investigating risks and manufacturer’s requirements along with worldwide legislations for the vehicle industry I will develop a DoIP gateway according to ISO 13400 which is connected to a CAN bus from one side and to a test tool via Ethernet from another side (Fig.1). UDS and DoIP protocols are implemented on both test tool and DoIP gateway. The practical part of the work is a complementary step in risk investigation that will be analysed. Having Ethernet as a carrier allows us to make use of different protocols, based on different needs like bandwidth, latency and real-time characteristics. This fact allows the network to have multi-type data which is usually the case with in-vehicle network. That is, we can use Ethernet not only for on-board diagnostics but also for other in-vehicle domains, such as the chassis, infotainment and comfort. At the end I will propose two models that will help the designers in this domain.

As evident from recent changes in NYSE and Nasdaq listing requirements, board independence is considered an important constituent of firms?? corporate governance structures. However, the empirical evidence regarding the impact of board structure on firm performance is mixed. Since firms employ a variety of governance mechanism to control agency problems, the significance of board independence may depend upon the strengths of other governance mechanisms. I study the importance of board independence from the viewpoint of an investor by examining the market reaction to board member resignation announcements. I then examine this market reaction in the context of each firm??s existing governance structure and business environment. I find that investors react more negatively when an outside director resigns from the board than when an inside or gray director resigns. More importantly, I find that investor reaction to outside director resignation is less negative when insider or non-affiliated blockholder stock ownership is high. This evidence suggests that board independence and insider ownership and non-affiliated blockholder ownership may serve as substitutes. Furthermore, the evidence indicates that firms may require higher board oversight when a large part of managerial compensation is based on stock incentives. This finding suggests that overly high levels of stock-based managerial compensation may exacerbate agency problems. Taken together, these results have important implications for choosing an effective set of governance mechanisms that may work independently or in combination with each other to mitigate the agency cost of equity.

This study examined the perceptions of school board members and superintendents of their role and responsibilities during conflict. The following research questions were the focus of this study: (1) What type of group interactions occurred among the school board members and between the board and the superintendent? (2) How did the board/superintendent relationship affect information processing, conflict management, and goal setting between the school board and the superintendent? (3) What ways did group structures, such as role identity, influence board/superintendent cohesiveness? (4) What ways did the superintendent's leadership have an effect on board/superintendent cohesiveness? A good working relationship between an elected school board and an appointed superintendent is crucial in order for the school district to attain its district goals and improve student achievement. The school board members need to understand not only their roles and functions, but also the role and function of the superintendent. If a healthy relationship is not developed, then the school district and their stakeholders will be in a constant power struggle (Estes, 1979). A well-rounded working relationship between the school board and the superintendent is imperative if the district wants to achieve the goals set by the school board and to meet the mandates and requirements from federal and state agencies. Utilizing a qualitative multiple case study with a social action system theory approach, direct observations, individual interviews, and document reviews were used to collect data in this research study. Open, axial, and selective coding were used to analyze the qualitative data that was collected. This study supported themes in practice that emerged through the data in school districts with healthy board/superintendent relationships. The themes included: (a) honesty; (b) free flowing communication; (c) mutual respect; and (g) trust. This study also supplemented the existing research with additional themes that emerged from the individual interviews, direct observation and documents. These emergent themes included: (a) lack of communication; (b) dishonesty; (c) favoritism. The results of this study provided information related to strategies that aid in the development and the improvement of the school board and superintendent relationship. It contributed to the field of knowledge by highlighting the importance of improving the school board and superintendent relationship. This study can serve as a guide for designing training for school boards and superintendents. It could also help determine if a single method or a combination of methods would help to develop or improve the relationship between the school board and the superintendent.
