Reconfigurable systems have the potential to boost hardware performance, efficiency and to stimulate development activity by enabling designers to work with flexible “modeling clay”, rather than with fixed units of hardware. One of the design issues not widely covered in current Advanced Logic Design courses is the issue of reconfigurable systems design. The proposed pedagogical approach enables the achievement of reconfigurable electronic systems representations through Finite State Machine (FSM), and may be helpful for teaching disciplines, in subjects such as reconfigurable computing and advanced digital systems. The approach intends to cover topics such as architectures and capabilities of field-programmable logic devices; system specification, modelling, and synthesis of digital systems; design methodology; computer-aided design tools; reconfiguration techniques. FSMs are probably the most widely used control components in digital systems. The accepted FSM design methodology taught today is problem oriented, especially its combinatorial part. This approach makes changes to the design complicated and undesirable. In contrast, in the new suggested approach, the emphasis is on the automata behavior and not on its implementation logic. The result of this approach is a more flexible and less complicated design abilities that uplift the course to a more intense and focused levels while enabling at the same time to perform a larger amount of experiments, and enhance the students’ self-efficacy. The proposed design method for FSM implementation with both combinational part and state memory part is built primarily from RAM blocks. The basic components of the circuit are utilizing the FPGA’s RAM blocks, by reprogramming these one can provide for different functionality. The design procedure is automated by software shell that converts the FSM representation in Kiss2 format to a VHDL description that corresponds to the proposed architecture. This paper suggests methods for the design of a reconfigurable FSM to be used in Advanced Logic Design course, and deals with the following aspects: a) system formalization by high (behavioral) level of abstraction; b) RAM based FSM architecture; c) reusable templates d) software system for FSM static reconfiguration. In addition, the proposed approach enables non-hardware background people to be able to control algorithm representation as FSMs and it also provides an additional motivation for students since the reconfigurable systems concept may be linked to studies in other disciplines; and a dynamic reconfiguration is overviewed.

Abstract The tire technology related with the computational mechanics is reviewed from the standpoint of yesterday, today, and tomorrow. Yesterday: A finite element method was developed in the 1950s as a tool of computational mechanics. In the tire manufacturers, finite element analysis (FEA) was started applying to a tire analysis in the beginning of 1970s and this was much earlier than the vehicle industry, electric industry, and others. The main reason was that construction and configurations of a tire were so complicated that analytical approach could not solve many problems related with tire mechanics. Since commercial software was not so popular in 1970s, in-house axisymmetric codes were developed for three kinds of application such as stress/strain, heat conduction, and modal analysis. Since FEA could make the stress/strain visible in a tire, the application area was mainly tire durability. Today: combining FEA with optimization techniques, the tire design procedure is drastically changed in side wall shape, tire crown shape, pitch variation, tire pattern, etc. So the computational mechanics becomes an indispensable tool for tire industry. Furthermore, an insight to improve tire performance is obtained from the optimized solution and the new technologies were created from the insight. Then, FEA is applied to various areas such as hydroplaning and snow traction based on the formulation of fluid–tire interaction. Since the computational mechanics enables us to see what we could not see, new tire patterns were developed by seeing the streamline in tire contact area and shear stress in snow in traction.Tomorrow: The computational mechanics will be applied in multidisciplinary areas and nano-scale areas to create new technologies. The environmental subjects will be more important such as rolling resistance, noise and wear.

A piled raft foundation consists of a thick concrete slab reinforced with steel which covers the entire contact area of the structure, in which the raft is supported by a group of piles or a number of individual piles. Bending moment on raft, differential and average settlement, pile and raft geometries are the influencing parameters of the piled raft foundation system. In this paper, a detailed review has been carried out on the issues on the raft foundation design. Also, the existing design procedure was explained.
