Almost instructions are completed within a single cycle. The designed DSP has been verified by comparing the results from CBS (cycle based simulator) and those of HDL simulation through the single instruction set test and the instruction combination test, and real audio applications. Finally, we confirm by the HDL simulation that the DSP carried out successfully out ADPCM and MPEG-2 AAC decoding algorithm.

The power generator is used as an important component of backup power systems in a series hybrid system which is one type of electric hybrid propulsion systems devised to enhance the fuel efficiency of a vehicle. The developed power generator (PG) system is for the vehicle system application. The system is composed of a diesel engine and a 60 kW induction generator and their control units. The traction motor is driven by a battery bank that is in parallel with power generator. The DC output of the system is driven to the high voltage DC link with a battery bank and supplies electrical power to charge the battery bank or to power loads in the DC link. This paper describes the power generator system's specifications, the control block diagram and the result of fuel efficiency tests carried out to evaluate the system's performance in reduction of fuel consumption.","PeriodicalId":103784,"journal":{"name":"2006 International Forum on Strategic Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125487676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On experiment, we use the modeling steel drum instead of real reactor and 4 accelerometer sensors for acquiring the impact signal. And the computer is connected the accelerometer sensor input and used for monitoring and analyzing of impact signal with Lab-view and Matlab programs.

The microstructure of the composites revealed that the TiB2 dispersoids with the particle size of smaller than 250 nm uniformly distributed in Cu matrix. The sintered samples obtained approximately 99% in relative density after sintering at 650 degC for 5 min. The fine dispersed TiB2 dispersoids in Cu matrix was the main reason to improve the mechanical properties of the composites. The hardness reached a value of 74 HRB. The result of tensile test showed that the ultimate tensile strength, yield strength and Young modulus increased from 187 MPa, 158 Mpa and 119 GPa for pure Cu to 485.7 MPa, 355.3 MPa and 157 GPa for the composites, whereas the electrical conductivity remained a high value of 83 % IACS.

The problem is solved by the Lekhnitskii method of complex potentials written in the form of Cauchy-type integrals along the defect contours with unknown integrand density function which has the root type singularity on the defect tips. The boundary-value problem is reduced to a system of singular integral equations subject to the conditions for the displacements to be single-valued upon circulating the closed contours around the cuts and equilibrium conditions for rigid inclusions. To illustrate the efficiency of the method proposed, some specific plate bending problems are solved. The stress distribution in the vicinity of the defect tips are studied for various plate configurations and orientation of defects. For isotropic plates, the solutions are obtained by setting appropriate numerical values of the anisotropic constants.","PeriodicalId":103784,"journal":{"name":"2006 International Forum on Strategic Technology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117011096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the TiW (titanium tungsten) film as a contact material has been deposited by RF magnetron sputter and annealed with vacuum furnace process. The specific contact resistance of the TiW contact was measured by using the C-TLM (circular transmission line method). Contact phase and interfacial reaction between TiW and poly 3C-SiC at high temperature were also analyzed by XRD (X-ray diffraction) and SEM (scanning electron microscope). TiW/poly 3C-SiC thin-films did not show cracks on the TiW film and any interfacial reaction after annealing. Especially, when the TiW/poly 3C-SiC thin-film was annealed at 800deg for 30 min., the lowest contact resistivity of 2.90times10-5 Omega-cm2 was obtained owing to the improved interfacial adhesion. Therefore, the good ohmic contact of poly 3C-SiC thin-films using the TiW thin-film are very suitable for microsensor applications in vehicle engine fields.","PeriodicalId":103784,"journal":{"name":"2006 International Forum on Strategic Technology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132450766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The location of the breakage is where considerable stress concentration occurs and moreover the bending moment is at the maximum. Macrofractographic features associated with rotating-bending fatigue are evident on the fracture surface. The measured surface strain of the spindle varies cyclically as the spindle rotates and supports the rotating-bending fatigue. The X-lift is not perfectly symmetrical with respect to the horizontal plane. The unsymmetrical deformation can occur and cause the bending of the spindle. The 3-D finite element analysis of the X-lift revealed the bending of the spindle.","PeriodicalId":103784,"journal":{"name":"2006 International Forum on Strategic Technology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116372587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
