Available Information

Biomass cofiring in existing coal fired boilers has emerged as one of the most prospective technologies in order to address voluntary reduction of green house gases and other emissions, potential portfolio standards, customer service etc. within the context of deregulations. Pilot plant test results have confirmed the potential of biomass cofiring with coal for commercial use. However, being a new and developing technology, there is hardly any tool available for estimation of variation in performance of an existing coal fired boiler due to its retrofitting for biomass cofiring. A predicting tool is developed to estimate this performance variation using available information of pilot plant test results in literature or from data of plant operating with biomass. In order to incorporate future available information, this is developed in a flexible environment of Model Development Kit (MDK) of IPSEpro, a commercially available heat and mass balance program. Development of the models for this predicting tool as well as its limitations and possible future improvement has been discussed in this paper. Some results regarding estimation of change in efficiency, emissions and associated costs using this developed predicting tool has been presented.

The study was conducted using the method of model development research. Learning tools developed in this study are the syllabus, lesson plans; worksheets based contextual, attitude assessment instruments and scientific reasoning of students. The device was developed in the context of learning materials rocky shore ecosystems. The results found that the contextual-based Student worksheet is considered good in all indicators of assessment conducted by the validator (learning media expert, expert learning materials, biology teachers and peers). Student worksheet ecosystem-based contextual material rocky shore ecosystems that meet the criteria on the basis of its constituent components increased the students' scientific reasoning for using contextual syntax right, looks at the value of students who have increased in terms of the scores of pre-test and post-test before and after use student worksheet developed contextually based, and there are significant differences in the data post-test results of students in the experimental class and the control class.Kata Kunci: LKS, CTL, Scientific Reasoning

ABSTRACTOBDH (On-board data handling) is a satellite subsystem that receives, processes, decides and executes commands from and to satellites. OBDH is built on two systems namely hardware and software integrated system (firmware system). In terms of hardware, OBDH uses a processor with 32bit RISC architecture, 128/256 Kbyte internal memory and a firmware system that is built using primitive programming. This programming uses the super loop architecture program and interrupt to manage the system to function properly. Problems occur when an error occurs in one of the functions in the interrupt routine resulting in failure of interpretation of commands or data from satellite sensors. This paper describes the implementation of the error patching methods on the LAPAN-A3/IPB Satellite OBDH firmware system in order to keep the system working well. Initial verification through testing on the ground have been successfully performed using engineering model of OBDH and hardware in the loop simulators (HWIL) module. Based on the test results, implementation on satellite has also been successfully done.ABSTRAKOBDH (On-board data handling) merupakan salah satu subsistem satelit yang berfungsi menerima, mengolah, mengambil keputusan dan mengeksekusi perintah dari dan ke satelit. OBDH dibangun berdasarkan dua buah sistem yaitu sistem perangkat keras dan perangkat lunak yang terintegrasi (sistem firmware). Dari sisi perangkat keras, OBDH menggunakan prosesor dengan arsitektur 32bit RISC, 128/256 Kbyte memori internal, dan sistem firmware yang dibangun menggunakan pemrograman primitif. Pemrograman ini menggunakan arsitektur program super loop dan interrupt untuk mengelola sistem agar dapat berfungsi dengan baik. Permasalahan terjadi ketika terjadi kesalahan pada salah satu fungsi pada rutin interrupt sehingga mengakibatkan kegagalan interpretasi perintah atau data dari sensor satelit. Paper ini menjelaskan mengenai implementasi metode penambalan kesalahan pada sistem firmware OBDH satelit LAPAN-A3/IPB yang bertujuan untuk menjaga agar sistem tetap bekerja dengan baik. Verifikasi awal melalui pengujian telah berhasil dilakukan mengunakan engineering model OBDH dan modul hardware in the loop simulators (HWIL). Berdasarkan hasil pengujian, implementasi pada satelit juga telah sukses dilakukan.

ObjectivesThere are no established mortality risk equations specifically for emergency medical patients who are admitted to a general hospital ward. Such risk equations may be useful in supporting the clinical decision-making process. We aim to develop and externally validate a computer-aided risk of mortality (CARM) score by combining the first electronically recorded vital signs and blood test results for emergency medical admissions.DesignLogistic regression model development and external validation study.SettingTwo acute hospitals (Northern Lincolnshire and Goole NHS Foundation Trust Hospital (NH)—model development data; York Hospital (YH)—external validation data).ParticipantsAdult (aged ≥16 years) medical admissions discharged over a 24-month period with electronic National Early Warning Score(s) and blood test results recorded on admission.ResultsThe risk of in-hospital mortality following emergency medical admission was 5.7% (NH: 1766/30 996) and 6.5% (YH: 1703/26 247). The C-statistic for the CARM score in NH was 0.87 (95% CI 0.86 to 0.88) and was similar in an external hospital setting YH (0.86, 95% CI 0.85 to 0.87) and the calibration slope included 1 (0.97, 95% CI 0.94 to 1.00).ConclusionsWe have developed a novel, externally validated CARM score with good performance characteristics for estimating the risk of in-hospital mortality following an emergency medical admission using the patient’s first, electronically recorded, vital signs and blood test results. Since the CARM score places no additional data collection burden on clinicians and is readily automated, it may now be carefully introduced and evaluated in hospitals with sufficient informatics infrastructure.
