Academic literature on the topic 'Matrix Auto Body (Firm)'

Automobile is a typical multi-stage split charging and assembly manufactured product. It can be divided into engine, body, chassis and electrical four modules functionally. Auto parts proportion is defined as the ratio of purchasing costs of a given part to the total costs. In this paper, an auto parts proportion model is proposed by means of matrix and statistical analysis, a benchmarking proportion calculating model of various vehicle types is presented by means of average and mode comparison. On the basis of these models, target costs of auto-parts, systems and modules can be calculated. These models and methodologies have been used in the processes of new product development costs controlling and developed products costs reduction in a big scale automobile company.

This paper examines the intricate link between unobservable characteristics of directors on the corporate board and firm performance. It aims to extend the literature on corporate governance and firm strategic performance from the perspective of emerging African economies. A mix of performance measures were used (Tobin Q, return on assets, and share price) and unobservable characteristics were captured as a stochastic element or heterogeneity of observable board characteristics (board activity, gender diversity, size, and independence). The study applied non-linear generalized auto-regressive conditional heteroscedasticity model to examine the data set consisting of 299 firm-year observations from 23 financial firms listed on the Nigerian Stock Exchange from 2006 to 2018. Positive skewness and leptokurtic distribution were found for all the variables. Correlation matrix revealed no multicollinearity, as the highest value was 0.2386. Empirical results suggest that unobservable characteristics significantly and positively influence firm performance as measured by return on assets and share price. This is because the coefficient of the lagged-value of the variance scaling parameter is positive and significant at the 1% level. However, with respect to Tobin Q measure, the result was positive but not significant at the 5% level. Implicitly, the result is sensitive to performance proxies. Accordingly, this study concludes that unobservable characteristics drive firm performance. It is recommended that boards and regulators should pay attention to unobservable characteristics.

This paper is concerned with the improvement of a tensile test method and the material properties of carbon fiber reinforced polymer manufactured by resin transfer molding considering stacking sequences at various strain rates for auto-body. Auto-body structure experiences the strain rates up to several hundreds per second during car crash. In order to apply the carbon fiber reinforced polymer panel into auto-body structures, it is critical to acquire the material properties of carbon fiber reinforced polymer at various strain rates considering stacking sequences. The tensile test method is improved for acceptable test results. Test specimens are modified for high-speed tensile tests of carbon fiber reinforced polymer in order to achieve designated strain rates and eliminate the effect from unfavorable conditions of inhomogeneity of deformation. Various types of grip tab materials are employed for acceptable failure modes. Tensile tests have been carried out with non-crimp fabric made by 50K high strength carbon fiber (NCF) and woven fabric made by a 2/2 twill pattern of 3K high strength carbon fiber (TWILL) with different stacking sequences of 0° and 90° unidirectional cases as well as [0°/90°] and [45°/−45°] symmetric cases. Digital image correlation method and force equilibrium grid method are adopted for strain and stress measurement of a carbon fiber reinforced polymer specimen during a tensile test. The material properties acquired indicate that the carbon fiber has little rate dependency, while the epoxy matrix has remarkable rate hardening at strain rates from 0.001 s−1 to 100 s−1.

An automobile company in this research faced the consistency problem from the chemical concentration in degreasing bath which was one of the stages in the pretreatment process. The problem came from the proportion of total alkaline (T.Al) lower than the lower control limit (LCL) which was set at 18.2 points during February – May 2020. This resulted in the low values of Cp and Cpk, i.e. 0.83 and 0.51, respectively. To remedy the problem, Six Sigma (DMAIC) was applied to improve the process stability. The cause and effect matrix was used to analyse the potential causes of problems and prioritise the causes to solve. It was found that four (causes) factors were solved by auto titration and feeding controller installation to reduce variance and increase stability. Another one factor, quality of water, was improved by adding a check item to monitor and collect data during the initial implementation stage. The result after improvement showed that Cp and Cpk were increased to 1.82 and 1.52 in August 2020, respectively.

Abstract Introduction: Acute myeloid leukemia (AML) in first remission (CR1) with intermediate-risk cytogenetics and isolated NPM1 mutation carries a good prognosis. There is not a clear benefit to perform allogeneic stem cell transplantation (allo-SCT) in CR1, and this procedure is not usually recommended in these patients. High dose chemotherapy followed by autologous stem cell transplantation (auto-SCT) is a good therapeutic alternative in good-risk AML in CR1 associated with lower toxicity. Nevertheless, relapse remains as high as 40% in this subgroup. To evaluate the best consolidation strategy in AML with isolated NPM1 mutation, we retrospectively compared auto-SCT, related (MRD) and fully matched (10/10) unrelated (MUD) allo-SCT within the EBMT registry. Methods: We selected de novo adult AML with intermediate-risk cytogenetics harbouring an isolated NPM1 mutation without FLT3-ITD and transplanted in CR1 between 2005 and 2015. Results: Two hundred and fifty-six patients have been allocated. One hundred and twenty-five patients received an auto-SCT, 72 a MRD and 59 a MUD. Median age at SCT was 52.5-year-old (range, 18.9-77) and median follow-up was 30 months (range, 1.6-109.7). A normal karyotype was found in 86% of auto-SCT and 74% of allo-SCT (p=0.02). Molecular status was available in 55% of patients, with a higher proportion of complete molecular remission (CMR) before auto-SCT than before allo-SCT (84% versus 63%, respectively, p=0.005). There was no difference in the number of induction courses to reach CR1 between groups. The majority of patients have a good performance status at the time of SCT. Peripheral blood was more frequently used as stem cell source in auto-SCT compared to allo-SCT (97% versus 77%, respectively, p<0.01). Total body irradiation was administered in 23% of allo-SCT and in 3% of auto-SCT (p<0.01). Among allo-SCT, a myeloablative conditioning regimen was administered in 57% of the patients. In vivo T-cell depletion was more frequently in MUD than in MRD (70 versus 40%, respectively, p=0.001). The 2-year leukemia-free survival (LFS) was 62% in auto-SCT, 69% in MUD and 81% in MRD (p=0.02 for MRD versus auto-SCT or MUD). The 2-year overall survival (OS) was not significantly different among auto-SCT, MUD and MRD, reaching 82%, 81% and 85%, respectively (p=0.88). The 2-year non-relapse mortality (NRM) was 2.5% in auto-SCT and 7.5% in allo-SCT (p=0.04), without any difference between MRD and MUD. The 2-year cumulative incidence of relapse (RI) was significantly higher after auto-SCT (30%) than after MUD (22%) and MRD (12%, p=0.01). Among patients transplanted in CMR, RI was higher after auto-SCT and LFS was superior after allo-SCT (RI: 21 vs. 11 vs 4%; LFS: 61 vs 74 vs. 91 after auto-SCT, MUD, and MRD, respectively, p=0.04), although this difference did not translate into a different OS (82 vs. 77 vs. 90 after auto-SCT, MUD, and MRD, respectively). In the 28 patients not transplanted in CMR who received an allo-SCT, 2-year RI, LFS and OS were 33% (15-53), 63 (43-83), and 81 (65 - 96%), whereas only 10 patients with persistant MRD received an auto-SCT precluding firm conclusions. In multivariate analysis, MRD versus auto-SCT but not MUD versus auto-SCT was significantly associated with a lower RI (p<0.01 and p=0.13, respectively) and a better LFS (p=0.01 and p=0.31, respectively). Age correlated significantly with higher NRM (p<0.01). Donor type, and age were not significantly associated with OS. Conclusion: Allo-SCT using a sibling donor appears as a good consolidation therapy to prevent relapse for young patients with AML and isolated NPM1 mutation in CR1. Auto-SCT was followed by higher relapse risk and inferior LFS, but similar OS to both allo-SCT modalities. In patients with molecular persistence, allo-SCT was followed by a relatively favourable outcome, but the low number of patients with molecular data included in this series precludes more firm conclusions. The strategy for patients not transplanted in CMR remains to be further evaluated.

This article investigates the following basic question: in the relatively stable molecular environment of a vertebrate body, can a dynamic idiotypic immune network develop a natural tolerance to endogenous components? Our approach is based on stability analysis and computer simulation using a model that takes into account the dynamics of two agents of the immune system, namely, B-lymphocytes and antibodies. We investigate the behavior of simple immune networks in interaction with an Ag whose concentration is being held constant as a function of the connectivity matrix of the network. The latter is characterized by the total number of clones, N, and the number of clones, C, with which each clone interacts. The idiotypic network models typically become unstable in the presence of this type of Ag. We show that idiotypic networks that can be found in particular connected regions of NC-space show tolerance towards auto-Ag without the need for ad hoc mechanisms that prevent an immune response. These tolerant network structures provide dynamical regimes in which the clone which interacts with the auto-Ag is suppressed instead of being excited such that an unbounded immune response does not occur. Possible implications for the future treatment of auto-immune disease such as IvIg-treatment are discussed in the light of these results. Moreover, we propose an experimental approach to verify the results of the present theoretical study.

Hot stamping has been developed into a sophisticated stage with standardized technology and typical product USIBOR1500. Most of the hot stamped components from 22MnB5 blanks possess high strength-ductility with TS⋅El product from 10 to 15 GPa%. To meet the further requirement of automakers on body lightening, energy saving and impact safety, the new HFQPT process is proposed, i.e. Hot Stamping in combination with Quenching-Partitioning-Tempering treatment, for higher strength-ductility auto parts with TS⋅El product 20∼30 GPa%. Based on the key technology of AHSS in retained austenite RA and TRIP effect, the Q-P-T treatment is integrated to hot stamping process to obtain retained austenite on the martensite matrix to improve ductility of hot stamped ultra-high-strength components. A low temperature P-T furnace is added to the hot stamping line followed the hot pressing machine to perform Partitioning-Tempering treatment immediately after Hot Press Forming and Quenching, named as HFQPT process. The blank steels for new hot stamping process HFQPT line can be further developed on the basis of low alloyed TRIP assisted steels, Q-P steels and Q-P-T steels, and produced in traditional hot strip mill HSM or in compact steel production CSP line through thin slab casting & direct rolling to deliver ultra-thin-hot-strip (thickness t = 1.2 ∼2.0 mm).

Abstract Introduction Deep Full thickness burns require tangential excision of the burned tissues down to viable tissue. This often leaves exposed muscle, tendon and bone. Coverage of these areas is vital to limb salvage. Multiple modalities are necessary with these type of patients, such as, dermal matrix graft, split thickness skin graft, sprayed autologous cell suspension (ACS) and wound vacuum therapy(VAC). A dermal matrix provides a scaffold for tissue and vascular en growth that is suitable for accepting a skin graft and also provides a layer between the muscle, tendon, bone and the skin graft which improves movement and produces a more pliable graft. Biodegradable temporizing matrix(BTM), produced by PolyNovo Ltd, was used to cover the muscle, bone and tendon. This product has a silicone backing which can be delaminated once it has matured with tissue and vascular en growth for auto grafting. A combination of a wide meshed skin graft at 3:1 ratio and a sprayed ACS allows for faster healing and less donor site usage which decreases the overall wound burden. Methods A 73 y/o male with total body surface area burn of 24 % suffered deep full thickness burns to the bilateral lower legs. He underwent multiple debridements with management of the right leg with irrigating wound vacuum therapy. The deeper right leg had a wound base with that consisted of muscle from the thigh down onto the foot with exposed tendons and anterior tibial bone. The open wounds to the right leg were grafted with BTM for dermal substitute coverage. Once the BTM was mature it was delaminated, and the wound surface was covered with a 3:1 ratio split thickness skin graft (STSG) and sprayed on autologous cell suspension. This resulted in using less donor skin than a 1.5 or 2:1 meshed graft STSG which decreased his wound burden. Donor sites were also sprayed with ACS. Results We had nearly 100% take of the STSG and sprayed autologous suspension epidermal graft. There was a small area over the patella tendon where the BTM did not incorporate. This is though to be because of lack of immobilization of his knee and a pseudomonal infection. Donor sites healed faster and there were minimal open areas to the graft POD 11 excluding the patella area. Conclusions BTM can be used to provide a suitable dermal substitute in complex wounds when muscle, tendon and/or bone are exposed. Immobilization of the joints is necessary to allow the tissue en growth into the dermal matrix. Wide meshed graft with sprayed ACS can be used with good results with wound vacuum therapy. Decreased wound burden and time to heal open wounds of the graft and donor sites. Applicability of Research to Practice Use of a dermal matrix, wide mesh split thickness graft and sprayed epidermal ACS with wound vacuum therapy is a good option for limb salvage when vital structures are exposed.
