Intelligent systems are driven by the latest technological advances in so different areas as sensing, embedded systems, wireless communications or context recognition. This paper focuses on some of those areas. Concretely, the paper deals with wireless communications issues on embedded systems. More precisely, the paper combines the multi-hop networking with Bluetooth technology and a quality of service (QoS) metric, the latency. Bluetooth is a radio license free worldwide communication standard that makes low power multi-hop wireless networking available. It establishes piconets (point-to-point and point-to-multipoint links) and scatternets (multi-hop networks). As a result, many Bluetooth nodes can be interconnected to set up ambient intelligent networks. Then, this paper presents the results of the investigation on multi-hop latency with park and sniff Bluetooth low power modes conducted over the hardware test bench previously implemented. In addition, the empirical models to estimate the latency of multi-hop communications over Bluetooth Asynchronous Connectionless Links (ACL) in park and sniff mode are given. The designers of devices and networks for intelligent systems will benefit from the estimation of the latency in Bluetooth multi-hop communications that the models provide.

The article discusses the main provisions and the role of mechatronics in production in agriculture. A review of current and promising mechatronic systems for use in agriculture is carried out. It is noted that the use of scientific and technological advances in the field of mechatronics opens up new opportunities for solving multidisciplinary problems, and also makes a person dependent on technical means. The current state and world trends in the application and development of mechatronic systems in the field of agricultural production are investigated. The needs for the use of mechatronic systems and modules in the conditions of agricultural enterprises are analyzed and the problems associated with their implementation and use are identified. The purpose of creating such complexes is to achieve a combination of high productivity and at the same time flexibility of the technical and technological environment due to the possibility of its reconfiguration, which will ensure the competitiveness and high quality of products in world markets. In modern mechatronic systems, to ensure a high quality of implementation of complex and precise movements, it is necessary to apply intelligent control methods. To create intelligent systems, it is necessary to provide flexible interaction of components within the system and with the outside world. Current trends in the use of mechatronic systems and modules in agricultural production are determined. As the scope of application of mechatronic systems expands and international scientific and technical relations expand, it becomes more and more important to actively exchange new production and information technologies between their creators and users, between various groups of consumers and developers (research centers, enterprises of various forms of ownership, universities ). These forms of cooperation are implemented within the framework of international technology transfer. The development of mechatronics as an interdisciplinary scientific and technical field, in addition to obvious technical and technological difficulties, also raises a number of new organizational and economic problems.

On Chip

In the last years, embedded systems have evolved so that they offer capabilities we could only find before in high performance systems. Portable devices already have multiprocessors on-chip (such as PowerPC 476FP or ARM Cortex A9 MP), usually multi-threaded, and a powerful multi-level cache memory hierarchy on-chip. As most of these systems are battery-powered, the power consumption becomes a critical issue. Achieving high performance and low power consumption is a high complexity challenge where some proposals have been already made. Suarez et al. proposed a new cache hierarchy on-chip, the LP-NUCA (Low Power NUCA), which is able to reduce the access latency taking advantage of NUCA (Non-Uniform Cache Architectures) properties. The key points are decoupling the functionality, and utilizing three specialized networks on-chip. This structure has been proved to be efficient for data hierarchies, achieving a good performance and reducing the energy consumption. On the other hand, instruction caches have different requirements and characteristics than data caches, contradicting the low-power embedded systems requirements, especially in SMT (simultaneous multi-threading) environments. We want to study the benefits of utilizing small tiled caches for the instruction hierarchy, so we propose a new design, ID-LP-NUCAs. Thus, we need to re-evaluate completely our previous design in terms of structure design, interconnection networks (including topologies, flow control and routing), content management (with special interest in hardware/software content allocation policies), and structure sharing. In CMP environments (chip multiprocessors) with parallel workloads, coherence plays an important role, and must be taken into consideration.

At production of fabrics, including fabrics for agricultural purpose, an important role is played by the cor-rect adjustment of operation of machine main regulator. The quality of setup of machine main controller is determined by the proper selection of rotation angle of warp beam weaving per one filling thread. In the pro-cess of using the regulator as a result of mistakes in adjustment, wear of transmission gear and backlashes in connections of details there are random changes in threads length. The purpose of the article is the research of property of random errors of basis giving by STB machine regulator. Mistakes can be both negative, and positive. In case of emergence only negative or only positive mistakes operation of the machine becomes im-possible as there will be a consecutive accumulation of mistakes. As a result of experimental data processing for stable process of weaving and the invariable diameter of basis threads winding of threads it is revealed that the random error of giving is set up as linear function of the accidental length having normal distribution. Measurements of accidental deviations in giving of a basis by the main regulator allowed to construct a curve of normal distribution of its actual length for one pass of weft thread. The presented curve of distribution of random errors in giving of a basis is the displaced curve of normal distribution of the accidental sizes. Also we define the density of probability of normal distribution of basis giving errors connected with a margin er-ror operation of the main regulator knowing of which allows to plan ways of their decrease that is important for improvement of quality of the produced fabrics.

Much of the material dredged from the port of Rotterdam is contaminated to such a degree that it must be placed in specially constructed sites. The aim of Rotterdam is to ensure that the dredged material will once again be clean. This will entail the thorough cleansing of the sources of the contamination of the sediment in the harbours and in the River Rhine. The Rotterdam Rhine Research Project (RRP) is one of the means to achieve this based on: technical research, legal research, public relations and dialogues with dischargers. The programme for five selected heavy metals is almost complete. For many heavy metal discharge points between Rotterdam and Rheinfelden, a specially devised independent load assessment has been carried out four times. Balance studies were used to determine the relative contributions of the point discharges to the total. Currently the results are being used in an attempt to negotiate agreements with a selected number of the major dischargers. At present, more detailed balance studies are being set up and exploratory measurements carried out for organic micropollutants. It may be concluded that the research is progressing successfully and methods and techniques developed seem satisfactory and broadly applicable. The Rhine Action Programme encompasses an international effort to improve the quality of the Rhine water. Although the RRP plays a modest complementary role to the Rhine Action Plan, there is no doubt of the value of this Rotterdam initiative. The mode of work followed in the RRP contains elements that can be of use in combatting the contamination of the North Sea by rivers other than the Rhine.

Variable Quality

The flow and the water quality of the rivers vary throughout the year. Very frequently the environment protection authorities set up a quality objective for the river water and this mini mum quality level is constant. So, it wou1d seem possible to accept variable quality standards for plant effluents. A first approach of the problem,by a small French task group,based on three actual cases leads to the provisory conclusion that such a regulation is suitable and presents economical benefit only in some very limit ed cases.

Abstract Introduction COVID-19 has placed unprecedented demand on services at ELHT and it has become necessary to have telephone clinics to reduce the number of face-to-face clinics. A ‘telephone triage clinic’ was set up for referrals from A&E. Our project evaluated patient and clinician satisfaction on this. Method We carried out a retrospective telephone questionnaire with patients over a one-week period during the pandemic. We focussed on overall satisfaction of the consultation and quality of communication. Consultants were also surveyed for their opinion on the clinics. Results From 30 patients, 77% said they were ‘very satisfied’ with the overall experience. 80% of patients were ‘very satisfied’ with the overall length of the telephone consultation. 50% of patients felt the clinician was only ‘adequately’ able to assess them over the telephone. The consultants were less satisfied with the overall experience of telephone consultation. A common theme was that they felt ED documentation could be improved to help inform ongoing management. Conclusions Overall, patients were satisfied with the consultations. It has been successful in minimising face to face consultations however some presentations necessitate further evaluation. We need to identify those injuries appropriate for virtual follow up and design a local protocol for these.
