The implementation of multi-level control schemes for large industrial processes is discussed, with particular emphasis on the problems of data transmission between computers operating at various levels in the system. The operation of one type of inter-processor data link is considered in detail and its relevance as a research facility for hierarchical control systems is demonstrated. Applications which make use of this facility are presented illustrating the diverse data transmission requirements of multi-level systems.

It is the key factor that the barge adjustment of large-scale structures’ ro-ro ship when the structure moves onto the barge. Generally, the common method on-site shipment is manual measurement which is a waste of time and labor power, at the same time, Barge adjustment is inaccurate and can not fundamentally solve the problem of the stability and real-time adjustment of the barge. In this paper, these questions are discussed based on the auto barge adjustment centralized in the computer, sensor and other technologies. In the process of ro-ro ship, the automatic computer control has been analyzed which makes the barge adjustment more timely, accurate and ensures real-time stability and accuracy of barge adjustment. Depending on the specific project case, it proves the feasibility and effectiveness of this method.

AbstractDirected cell migration is critical across biological processes spanning healing to cancer invasion, yet no existing tools allow real-time interactive guidance over such migration. We present a new bioreactor that harnesses electrotaxis—directed cell migration along electric field gradients—by integrating four independent electrodes under computer control to dynamically program electric field patterns, and hence steer cell migration. Using this platform, we programmed and characterized multiple precise, two-dimensional collective migration maneuvers in renal epithelia and primary skin keratinocyte ensembles. First, we demonstrated on-demand, 90-degree collective turning. Next, we developed a universal electrical stimulation scheme capable of programming arbitrary 2D migration maneuvers such as precise angular turns and migration in a complete circle. Our stimulation scheme proves that cells effectively time-average electric field cues, helping to elucidate the transduction time scales in electrotaxis. Together, this work represents an enabling platform for controlling cell migration with broad utility across many cell types.

Insight Into

A lab-scale biofilter was run continuously for 1½ years for combined denitrification and phosphorus removal. lternation between anaerobic and anoxic (nitrate) conditions was used to obtain an enriched culture of denitrifying, phosphate accumulating organisms. Batch experiments were performed to test the importance of diffusion and zonation in the biofilm. Half- and zero-order anaerobic phosphate release and anoxic phosphate uptake rates were verified, which was taken as an indication of a zonated biofilm. To investigate the practical applicability of the process, the development of a computer model is necessary due to the high complexity of the process. AQUASIM is suitable for this purpose. The model can provide insight into what goes on inside the biofilm and act as a tool when predicting required tank sizes, optimal phase lengths and biofilm thickness etc. for a large-scale system. For control of the process, on-line measurements and computer control of the system are essential.

A new automated 96 channel microdispenser is described for precise, high speed dispensing of microliter volumes of reagents. The Hydra 96™ is a programmable instrument composed of 96 glass syringes arrayed in microplate format that fill and dispense in unison under computer control. Studies show the instrument has less than a 2% coefficient of variance (C.V.) across the syringe array when dispensing between 0.5–20.0 μl of reagent. Blot hybridization studies demonstrate a simple rinsing protocol using 2% bleach efficiently cleans the system of DNA preventing downstream sample contamination without affecting subsequent PCR reactions. Current uses of the instrument in assembling microassays used in large scale genetic mapping and sequencing projects and compound library screening are discussed.

Abstract Stacking robot is one of the core equipment of automated warehouse, and it is also the main cargo access equipment. Stacking robot consists of three main parts: control system, measurement and servo system and mechanical system. With the development of computer control technology and logistics storage technology, stacker is widely used and its technical performance is getting better and better. At the same time, in order to meet the requirements of large-scale three-dimensional warehouse, its overall height keeps climbing. Automatic storage has become one of the symbols of enterprise modernization, and stable, reliable and practical stacking robot is the key. The stacking robot is the carrier to realize the flow of materials. It runs back and forth in the high-rise shelf roadway to store or take out the goods, so as to realize the flow of materials. The advantages of automated warehouse must be fully reflected by the stacker. As the most important handling equipment in the three-dimensional warehouse, the stacker requires fast, stable, safe, reliable and accurate operation. In this paper, the structure and system of the stacking robot for oilfield pipe products are analyzed.
