航空产业出现制品生产瓶颈,在瓶颈环节中抽象出的问题是在全部设备连续生产的情况下,如何确定上游设备在制品生产的批量才能使多台下游设备的需求得到满足。将这类生产环节的协调过程做成模型,分析得出周期性算法,并分析了周期性算法的前提、优点、步骤、性质的相关概念。根据生产中的实际情况,验证算法的效果,证明周期性算法是能够解决问题的,而且是优于当下存在的其他算法的。 相似文献

Prof. Peter Gruss, president of the Max Planck Society （MPS） and a winner of China＇s National Award for International S＆T Cooperation in 2007, has long been committed to promoting the scientific cooperation between China and Germany. As early as in the 1980s, he went to Shanghai to teach advanced experimental techniques at the Guest Laboratory cosponsored by CAS and MPS. Since 2002 when he assumed the office of MPS president, Prof. Gruss has further strengthened the partnership between the two organizations. 相似文献

As one of the first Partner Groups which were initiated to foster scientific exchange and interaction between the Max Planck Society (MPS) and the Chinese Academy of Sciences (CAS), the Partner Group led by Lu Ke was established on April 1, 1999. During the past five years, the group has received substantial support from the CAS for equipment and from the MPS for personnel and travel expenses. Extensive and productive collaborations between the research staff and students of the Partner Group with several professors (departments) in the Max Planck Institute for Metals Research (MPI-MF) have led to significant advances in synthesis, mechanical properties, melting and superheating of nanostructured metals. The research is well recognized internationally and a substantial number of publications in high quality, peer-reviewed journals (including Science and Physical Review Letters) have resulted. At the MPI-MF, Ke Lu has collaborated with Manfred Ruhle and Reinhard Luck on crystallization studies, with Eric 相似文献

The mucopolysaccharidoses (MPSs) are a heterogeneous group of rare inherited disorders caused by deficiency of lysosomal enzyme necessary to break down mucopolysaccharides or glycosaminoglycans (GAGs). We had combined clinical findings and ophthalmological features. Biochemical test for urine glycosaminoglycans was done for confirmation of diagnosis in the patient. The case of Sanfillippo’s disease was characterized by delayed development, hyperactivity with aggressive behaviour. Coarse facial feature, hirsutism and sleep disorder. Urine GAG tests for MPS was positive in the case. Based on clinical findings and biochemical tests for MPS, this case was diagnosed as a type III mucopolysaccharidoses. Urinary GAG’s electrophoresis is an important screening test for MPS suspected cases. 相似文献

Mucopolysaccharidoses (MPS) are a group of genetic diseases and its diagnosis is a challenging task due to multiple differential diagnosis. We had combined clinical findings, radiological and ophthalmological features. Biochemical test for urine glycosaminoglycans (GAG) was done for confirmation of diagnosis in the patient. The case of Sanfilippo disease was characterized by slowly progressive, severe CNS involvement with mild somatic disease. Radiological features were suggestive of Sanfilippo disease and urine GAG test for MPS was positive in the case. With the clinical features we had multiple differential diagnoses. The radiological investigations minimized the list and the biochemical test confirmed GAG in urine. In this case the combination of clinical, radiological and biochemical findings confirmed the diagnosis of Sanfilippo disease. 相似文献

Methods for assaying lysosomal diseases in dried blood samples are very useful today due to its several advantages related to the stability of samples, its transportation, handled and analysis, and its potential use for newborn screening compared to traditional methods in leucocytes samples. For this reason, it is important to validate these assays before being used in routine laboratory. Because of different in biological markers based on ethnicity, we aimed this study to validation a DBS-based fluorometric assay for measurement of α-l-Iduronidase activity for diagnosis of MPS I patients in Iran. DBS samples were collected from 15 MPS I patients and 60 healthy age matched subjects. Diagnostic value, biological variance and α-l-Iduronidase activity were determined. DBS α-l-Iduronidase activity was significantly higher in male subjects than in female group. Using a cut-off level of 1.08 µmol/spot 20 h, sensitivity and specificity were 100 and 98 %. The linearity of test was proved and we showed that within-run and between run precision were 5.6 and 14.66 %. Measurement of α-l-Iduronidase activity in DBS samples is an accurate test for diagnosis of MPS I and because of its rapid shipping and simplicity to keeping, DBS-based enzyme activity could be considered as a useful diagnostic tool in this disease. 相似文献
