The thermal simulation and control system is the core of vacuum thermal test of the spacecraft, which is used for tests design, data acquisition, thermal simulation and control, data management. In order to meet these application requirements, research contents and methods of keys techniques were expounded, which mainly includes three aspects: modeling analysis of test design workflow based on UML, architecture design and function design of test design software based on database and ASP; establishing universal driver function library based on VISA and SCPI, parallel driver design based on multithread technology; control mode and control algorithm design based on control objects requirements of the thermal simulation. Then the paper introduces the application of the research achievements, including test design software, data acquisition software, thermal simulation and control software. Finally, the paper prospects the main development direction of the thermal simulation and control technology along with the booming development of the China`s space industry.

ABSTRAK Berbagai masalah gizi diderita oleh sebagian besar masyarakat Indonesia dan salah satu masalah gizi utama adalah anemia gizi besi. Salah satu upaya untuk memperbaiki pola konsumsi pangan dan pola kebiasaan yang bertujuan untuk menanggulangi anemia dikalangan masyarakat terutama ibu hamil dengan melalui peningkatan pengetahuan, sikap dan perilaku seseorang dengan penyuluhan gizi dan mengonsumsi tablet tambah darah. Penelitian ini bertujuan mengetahui pengaruh penyuluhan gizi, asupan gizi dan pemberian tablet tambah darah terhadap kadar hemoglobin ibu hamil di Puskesmas Paccerakkang Kota Makassar. Jenis penelitian ini merupakan penelitian analitik dengan rancangan one-group pre-test and post-test design. Data diperoleh dari hasil Pre test dan Post test menggunakan kuesioner, pengambilan Hb, recall 24 jam dan data tablet tambah darah yang di konsumsi. Kadar hemoglobin ibu hamil pada awalnya anemia (100%) dan pada akhir terdapat sebanyak 8 orang (53,33%). Hasil pre dan post test ibu hamil yang memiliki criteria baik sebelum mendapatkan penyuluhan gizi sebanyak 2 orang (13,33 %) dan setelah mendapatkan penyuluhan gizi sebanyak 4  orang (26,67%). Asupan gizi (energi) ibu hamil yang memiliki criteria asupan baik di awal sebanyak 1  orang (6,67 %) dan di akhir sebanyak 9  orang (60%). Asupan gizi (protein) baik di awal sebanyak 3 orang (20 %) dan di akhir sebanyak 4  orang (26,67%). Pada umumnya asupan Fe di awal dan di akhir dari 15 ibu hamil 100% tergolong kurang. Ibu hamil yang mengkonsumsi tablet tambah darah dengan baik sebanyak 6 orang (40%). Disarankan ibu hamil turut berpartisipasi setiap pemeriksaan rutin yang diadakan oleh Puskesmas guna mencegah terjadinya masalah gizi.

Fluidised-bed steam dryers have been in use for industrial-scale drying of pressed beet pulp for more than 20 years. This highly energy-efficient process can be considered to be state of the art in the industry. Scientific laboratory and pilot-plant testing have provided the basis for a detailed description of the principles of fluidisation and drying in superheated water vapour. Advances in production data acquisition, in particular regarding the options for the real-time presentation and evaluation of high-resolution operating data (Industry 4.0), have opened up new potentials for optimisation of the drying process in fluidised-bed steam dryers. By analysing and interpreting sequences of events, or simultaneous events, it is now possible to analyse process behaviour in great depth. This allows malfunctions to be avoided by improved design or, assisted by suitable measuring and control systems, to be detected at an early stage. Failures can then be prevented altogether by initiating automated countermeasures. On the basis of more recent insights gained from the analysis of faults and disruptions using modern operating data acquisition, BMA’s fluidised-bed steam dryer (WVT) has been subjected to fundamental technological and technical improvements, so it now meets today’s demands for efficiency and reliability. Modifications include the product inlet, the distribution plate and several other parts, in addition to the known and patented PPS (Plug Protection System; EP 2457649 B1), and the patented rotary weir (EP 2146167 B1).
