E-LOTOS is the new extended version of LOTOS, currently under consideration by the ISO/IEC committee. The paper presents the complete process of producing the formal specification of a real time scheduler from its informal description. During this process, a semi formal model of the scheduler is first built that helps identify the critical parts of the scheduler. This model is then used as the basis for the formal specification of the scheduler. Finally, the degree at which E-LOTOs has succeeded in describing the critical parts of the scheduler is examined. The chosen, real life paradigm is the Link Active Scheduler (LAS) of the Fieldbus Foundation (FF) Data Link Layer (DLL) protocol. Its formal specification has not been presented before

This research aimed to get information about the relevance of physics with the automotive learning in SMK of light vehicle techniques or Teknik Kendaraan Ringan (TKR) competence. This study was a qualitative research with the subjects students grade X of TKR class at three different SMKs in Pekalongan. The data were collected by conducting library research, tests, and interviews. The data obtained were analyzed qualitatively descriptive. The results of library research analysis on the physics basic competence of SMK in curriculum 2013 with the TKR basic competence indicated a relevance among them. Physics materials that were compatible with the TKR basic competence included measurement, Newton's law, work and energy, torque, elastisits properties, static and dynamic fluids, heat and temperature, thermodynamics, dynamic electricity, laws of magnetism, and alternating current circuits, while the incompatible physics material consisted of straight and circular motion, momentum, impulse, vibrations, and waves. Students physics test in three different SMK resulted has not yet reached a classical thoroughness. At last, the interviews with the automotive teachers indicated the relevance of students 'physics values with students' abilities in the automotive vocational practice.

This method is thought to support students in taking responsibility for their own learning (with careful selection of the supporting material, which is often in the form of pre-recorded video lectures), to improve engagement and usefulness of contact time, and to provide a richer learning environment for students. This article provides some examples of using the flip method in science, engineering and product design pitched at A-level and first-year undergraduate levels in the UK.

Harmonic distortion in the sound field is significant and varies with different transducer arrangements. The directivity increases with increasing frequency and varies with the transducer selection procedure. Randomizing the selection of transducers at each sample interval improves the directivity but introduces high-frequency noise into the radiated sound field.

This paper gives an overview of the current use of videocasts in engineering and design education. Videocasts are the video equivalent of podcasts: online, available and video based. They can be generated and published to demonstrate a variety of information and skills, including traditional lectures, software demonstrations (e.g. CAD, spreadsheets, programming software), animations and hands-on practical demonstrations (e.g. drawing techniques, model making, analytical workings). Videocasts can also be used to assess student work, providing a useful insight into students' understanding and strategy. A critical evaluation of the various videocast types is presented. In particular, practical issues are discussed for publication on generic institutional gateways (e.g. intranet and VLE systems such as Blackboard) and also standalone websites. This paper also serves as a guide to lecturers and teachers who want to use videocasts to complement and extend traditional teaching methods. Guidelines are provided for preparation, presentation and post processing of material. Case studies are discussed to highlight particular strengths and weaknesses in generating the videocasts for various activities in a range of environments. In summary, videocasts are a powerful tool for educators, especially in higher education where student attendance and commitment can be volatile. Used efficiently, they can be perpetuating, save time and present academics with an opportunity to multitask. They can give students a flexible learning environment and support diverse learning styles.

For instance the Royal Academy of Engineering (RAEng) recently published its curriculum map for introducing ethics into the engineering curriculum for courses that do not explicitly cover this at present. The guidelines include a suggested three step approach, including an audit of current methods, a plan of action for the future and the implementation of the plan. The authors are attempting to begin the process of introducing ethics into its engineering and product design courses using these three stages. Currently, the team is about to enter the final and potentially most challenging stage of the process. This paper is presented as a case study, giving an overview and evaluation of the experiences of this team thus far, with reference to other case studies from overseas and our own experiences in the UK.

In this paper, we present a Unicast Bandwidth Efficiency Routing Algorithm (UBERA) for mobile devices that are streaming video contents from a video server. The algorithm can adapt to different number of mobile devices with different level of mobility and different location. Routing decisions are based on the availability of the packet(s) within a given geographical location. The video server identifies the availability of the packets it has earlier sent to a particular client and requests the packet(s) to be forwarded to the requesting client. Real live video programme was streamed using VLC media player and the collected packets size and packet inter-arrival times were used in all the simulations. Different simulations were conducted using OPNET Modeler. After conducting series of simulation tests, the algorithm showed low server and network load, low delay, high adaptability and robustness.
