Modern NIR analysers produce valuable data for closed-loop process control and optimisation practically in real time. Thus it is highly important to keep them in the best possible shape. Quality assurance (QA) of NIR analysers is an interesting and complex issue because it is not only the instrument and sample handling that has to be monitored. At the same time, validity of prediction models has to be assured. A system for fully automated QA of NIR analysers is described. The system takes care of collecting and organising spectra from various instruments, relevant laboratory, and process management system (PMS) data. Validation of spectra is based on simple diagnostics values derived from the spectra. Predictions are validated against laboratory (LIMS) or other online analyser results (collected from PMS). The system features automated alarming, reporting, trending, and charting functions for major key variables for easy visual inspection. Various textual and graphical reports are sent to maintenance people through email. The software was written with Borland Delphi 7 Enterprise. Oracle and PMS ODBC interfaces were used for accessing LIMS and PMS data using appropriate SQL queries. It will be shown that it is possible to take actions even before the quality of predictions is seriously affected, thus maximising the overall uptime of the instrument.

Abstract A foundry plant as a manufacturing system operates in accordance with the methods and principles making up the entire process of casting production, involving the use of machines and installations. One of the factors transforming the foundry plant’s static structure into the dynamic -processing structure is the compressed air. Practically each procedure making up the casting manufacturing process involves compressed air. Its sources include compressor machines connected to the receiving tanks, making up the compressed air transport installation. Two major aspects are to be addressed in compressed air management: the engineering and economic ones. The engineering aspect involves the manufacturing of compressed air with the required quality features and in the amount balancing its demand, whilst the economic aspect is associated with cost minimisation. This paper investigates the engineering aspects: air quality, with the main focus on air treatment processes to satisfy the constructional and operational requirements of air receivers present in the casting processes.

The Community Partnership Program in partnership with the Tani Rahayu Women's Group and the Bakpia Jurug Industry Association have succeeded in helping create economic independence. The results of this program are increased capacity and quality of production of bakpia and tempeh nuggets in the partner group. The implementation of mechanical and automation technology-based tools is able to increase the production capacity of tempe nuggets from 2 kg to 24 kg in a production time of 8 hours. While the implementation of the use of bakpia kumbu processing equipment was able to increase the production of 3 kg to 24 kg in a production time of 8 hours. The utilization of these tools has also been followed by quality assurance training and assistance, so that the quality of the products produced is uniform.

Current geopolitical and economic conditions for the functioning of railway transport in most post-Soviet states are such that it is extremely difficult to provide required quality of transport services and break-even operations at high expenses for maintaining the railway infrastructure and rolling stock. Dynamics of transportation of the Tajik Railway (TSR) is shown, which displays that most of its sections are classified as low-intensity ones. The paper proposes methodical principles, setting and qualitative analysis of the task of rationalization of operational work and organization of car flows for international transportation, taking into account the specifics of the Tajik Railway. There is a problem of complex maintenance of the efficiency of operational work in modern conditions based on the synthesis of the tasks of self-management (rational internal operational technology of the Tajik Railway) and coordination tasks (technological interaction with railway administrations of other states). Author substantiated the necessity of solving this problem. Proposed classification of technological restrictions and controlled variables in the performance of transport takes into account methods for changing external conditions for the functioning of the railway landfill and methods for increasing internal efficiency of its operation. The search for the solution of the problem involves direct search of variants along its ordered set with clipping of groups of variants that do not correspond to constraints, with the subsequent finding of compromise control over a set of effective alternatives.

Education In India

Quality, as we know so far, was originally developed in the manufacturing industry. In the area of higher education, the adoption of quality control has been superficial and diluted by the exercise of academic . Further, the prevailing culture of universities is often based on individual autonomy, which is zealously guarded. Thus, it is usually difficult to apply the features of quality to higher education considering the fact that quality requires. However, the quality of higher education is very important for its stakeholders. Notably, providers (funding bodies and the community at large), students, staff and employers of graduates are. The most commonly grouped dimensions of quality are product, software and service. In the changing context marked by expansion of higher education and globalization of economic activities, education has become a national concern with an international dimension. To cope with this changing context, countries have been pressurized to ensure and assure quality of higher education at a nationally comparable and internationally acceptable standard. Consequently, many countries initiated “national quality assurance mechanisms” and many more are in the process of evolving a suitable strategy. Most of the quality assurance bodies were established in the nineties and after a few years of practical experience, they are rethinking many issues of quality assurance. At this juncture where countries look for experiences and practices elsewhere, the experience of India has many valuable lessons and this report is an attempt to share those developments..
