The consulting firm interviewed 200 European logistics and supply chain management experts for its analysis . According to the results , only 42% of respondents from the manufacturing sector have their own employees working on transport planning and monitoring, while the figure for retailers was only slightly higher at 53%. Only 35% of manufacturing companies have their own transport management system. Even less, 31%, use AI microservices for this purpose. Those already using them aim to improve delivery reliability or save freight costs in doing so. BearingPoint expects the importance of AI tools in transport management to increase significantly in the coming years. A survey conducted by the software manufacturer Inform in 2018 had already revealed that AI has led a rather shadowy existence in logistics to date. The reasons given for the sluggish implementation included lack of know-how, high costs, inadequate IT infrastructure and limited time resources.
Following similar collaborative projects with Stäubli Robotics and Yaskawa Motoman , the Sepro Group has now reached another far-reaching agreement: the French supplier of robots and industrial automation for the plastics industry and the Danish collaborative robots (cobots) specialist, Universal Robots , announced their cooperative partnership in May 2019. The idea going forward is for Sepro’s control platform Visual to be integrated into the cobots from Universal Robots, and Universal Robots technologies to seamlessly integrate into other Sepro robots and injection molding machines, where required. Sepro specifically developed the control platform Visual for robots used in plastic injection molding machines. All Sepro products, including the jointly marketed product lines of partners, are controlled by Visual and have the same user interface regardless of robot type. Sepro will provide the worldwide service for Sepro and Universal Robots solutions under the agreement.
In a pilot test, Heliatek glued 120 HeliaSol elements, a special solar film, to a 230 m2 area of rough concrete on a Schneller Mühle grain silo in Donauwörth, Bavaria. Together with Lechwerken (LEW) , a regional utility company from Augsburg, Heliatek plans to test the still young technology in a long-term test . The film is expected to deliver an output of around 10 kWp and generate around 4,400 kWh of electricity per year. The results of the test should contribute to further product development. Unlike conventional solar modules, the film can be applied to a wide variety of facade shapes and surfaces. Since there is no decline in output even at high temperatures, no ventilation distance to the substrate is required. The film can thus be glued directly to the facade. For the pilot test, the concrete facade was first treated with a special primer to strengthen the adhesion of the film adhesive.
Half of the 40 million euros in funding is financed from the supplementary budget of the Bavarian state and the other half by industry. The money is primarily slated to benefit the aerospace industry in Augsburg. MAI Carbon (MAI stands for “Munich Augsburg Ingolstadt”), a Carbon Composites e. V. (CCeV) initiative, will take care of the required coordination. This, in turn, is an Augsburg-based association of more than 200 companies and research institutes from Germany, Austria and Switzerland working in the field of high-performance fiber composites. Bavaria is leveraging the funding program to strengthen Augsburg’s position as one of the leading international locations for the research and use of lightweight construction materials such as carbon. In addition to the aerospace industry, the Bavarian automotive and sports industries as well as the e-mobility and environmental technologies, mechatronics, automation, IT and embedded systems sectors are also expected to benefit from the research.
The researchers from the universities of Göttingen, Duisburg-Essen and Trier entrusted various mixed teams with transport tasks, including vehicles. They measured the time the groups needed to meet the challenges. It turned out that transport processes were most efficiently coordinated by mixed teams of humans and machines. They also had the lowest number of accidents. The result surprised the scientists, as automated machine processes are generally regarded as highly efficient. The researchers concluded that “excessive fears” of job loss due to automation are unjustified: humans and machines are obviously at their best when working together. Safe and successful cooperation nevertheless requires a number of conditions to be fulfilled. The German Federal Institute for Occupational Safety and Health (BAuA) has already published several papers dealing with various aspects of human and machine interaction.
Large-scale plant construction in Germany must rethink its business models to better meet customer requirements in the future and remain competitive. This is a central demand resulting from the joint study conducted by the VDMA‘ s large-scale plant manufacturers’ group (AGAB) and the consulting company PwC. According to the study, the market needs to move away from the previous, technology-focused business models and toward an offering characterized by digital and data-driven services. In other areas, nevertheless, the study considers German large-scale plant construction as a global leader, for example in cybersecurity or virtual reality (VR): 94% of plant manufacturers already see VR as the essential basis of future success. The study, which can be viewed free of charge and sees itself as a guideline for successful digitization, identifies a total of 18 key factors for successful transformation, including the development of intelligent logistics concepts and cooperation with value chain partners.
North Carolina State University researchers have developed a technique to improve the characteristics of engineered tissues by using ultrasound to align living cells during the bio-fabrication process. "We've reached the point where we are able to create medical products, such as knee implants, by printing living cells," says Rohan Shirwaiker, corresponding author of a paper on the work and an associate professor in NC State's Edward P. Fitts Department of Industrial & Systems Engineering. "But one challenge has been organizing the cells that are being printed, so that the engineered tissue more closely mimics natural tissues. "We've now developed a technique, called ultrasound-assisted biofabrication (UAB), which allows us to align cells in a three-dimensional matrix during the bioprinting process. This allows us to create a knee meniscus, for example, that is more similar to a patient's original meniscus. To date, we've been able to align cells for a range of engineered musculoskeletal tissues." To align the cells, the researchers built an ultrasound chamber that allows ultrasonic waves to travel across the area where a bioprinter prints living cells. These ultrasonic waves travel in one direction and are then reflected back to their source, creating a "standing ultrasound wave." The soundwaves effectively herd the cells into rows, which align with areas where the ultrasound waves and the reflected waves cross each other. "We can control the alignment characteristics of the cells by controlling the parameters of the ultrasound, such as frequency and amplitude," Shirwaiker says. To demonstrate the viability of the UAB technique, the researchers created a knee meniscus, with the cells aligned in a semilunar arc - just as they are in a natural meniscus. "We were able to control the alignment of the cells as they were printed, layer by layer, throughout the tissue," Shirwaiker says. "We've also shown the ability to align cells in ways that are particularly important for other orthopedic soft tissues, such as ligaments and tendons." The researchers also found that some combinations of ultrasound parameters led to cell death. "This is important, because it gives us a clear understanding of both what we can do to improve tissue performance and what we need to avoid in order to preserve living cells," Shirwaiker says. To that end, the researchers have created computational models that allow users to predict the performance of any given set of parameters before beginning the biofabrication process. One other benefit of the UAB technique is that it is relatively inexpensive. "There's a one-time cost for setting up the ultrasound equipment - which can use off-the-shelf technology" Shirwaiker says. "After that, the operating costs for the ultrasound components are negligible. And the UAB technique can be used in conjunction with most existing bioprinting technologies. "We have a patent pending on the UAB technique, and are now looking for industry partners to help us explore commercialization," Shirwaiker says.
Biomedical engineers at Duke University have developed an automated process that can trace the shapes of active neurons as accurately as human researchers can, but in a fraction of the time. This new technique, based on using artificial intelligence to interpret video images, addresses a critical roadblock in neuron analysis, allowing researchers to rapidly gather and process neuronal signals for real-time behavioral studies. The research appeared this week in the Proceedings of the National Academy of Sciences. To measure neural activity, researchers typically use a process known as two-photon calcium imaging, which allows them to record the activity of individual neurons in the brains of live animals. These recordings enable researchers to track which neurons are firing, and how they potentially correspond to different behaviors. While these measurements are useful for behavioral studies, identifying individual neurons in the recordings is a painstaking process. Currently, the most accurate method requires a human analyst to circle every 'spark' they see in the recording, often requiring them to stop and rewind the video until the targeted neurons are identified and saved. To further complicate the process, investigators are often interested in identifying only a small subset of active neurons that overlap in different layers within the thousands of neurons that are imaged. This process, called segmentation, is fussy and slow. A researcher can spend anywhere from four to 24 hours segmenting neurons in a 30-minute video recording, and that's assuming they're fully focused for the duration and don't take breaks to sleep, eat or use the bathroom. In contrast, a new open source automated algorithm developed by image processing and neuroscience researchers in Duke's Department of Biomedical Engineering can accurately identify and segment neurons in minutes. "As a critical step towards complete mapping of brain activity, we were tasked with the formidable challenge of developing a fast automated algorithm that is as accurate as humans for segmenting a variety of active neurons imaged under different experimental settings," said Sina Farsiu, the Paul Ruffin Scarborough Associate Professor of Engineering in Duke BME. "The data analysis bottleneck has existed in neuroscience for a long time -- data analysts have spent hours and hours processing minutes of data, but this algorithm can process a 30-minute video in 20 to 30 minutes," said Yiyang Gong, an assistant professor in Duke BME. "We were also able to generalize its performance, so it can operate equally well if we need to segment neurons from another layer of the brain with different neuron size or densities." "Our deep learning-based algorithm is fast, and is demonstrated to be as accurate as (if not better than) human experts in segmenting active and overlapping neurons from two-photon microscopy recordings," said Somayyeh Soltanian-Zadeh, a PhD student in Duke BME and first author on the paper. Deep-learning algorithms allow researchers to quickly process large amounts of data by sending it through multiple layers of nonlinear processing units, which can be trained to identify different parts of a complex image. In their framework, this team created an algorithm that could process both spatial and timing information in the input videos. They then 'trained' the algorithm to mimic the segmentation of a human analyst while improving the accuracy. The advance is a critical step towards allowing neuroscientists to track neural activity in real time. Because of their tool's widespread usefulness, the team has made their software and annotated dataset available online. Gong is already using the new method to more closely study the neural activity associated with different behaviors in mice. By better understanding which neurons fire for different activities, Gong hopes to learn how researchers can manipulate brain activity to modify behavior.
Natural rubber from rubber trees is a raw material with a limited supply. Synthetically produced rubber, on the other hand, has not yet been able to match the abrasion behavior of the natural product, rendering it unsuitable for truck tires. But now, for the first time, a new type of synthetic rubber has been developed that achieves 30 to 50 percent less abrasion than natural rubber. Truck tires have to put up with a lot: As a result of the heavy loads they carry and the long distances they travel every day, they are subject to heavy wear and tear. Conse-quently, the treads of the tires are manufactured primarily from natural rubber that comes from rubber trees and to date has demonstrated the best abrasion characteris-tics. Before now, artificially manufactured rubber has been unable to match the perfor-mance of natural rubber, at least in this respect. The problem with natural rubber is that the security of supply for this important raw material is endangered. In Brazil, the original home of the rubber tree, the fungus Microcyclus ulei is laying waste to whole plantations. If the fungus crosses over to Asia, where major cultivation areas are lo-cated today, the global production of rubber will be threatened. Biomimetic synthetic rubber with optimized abrasion behavior (BISYKA) In view of this threat, researchers at the Fraunhofer Institutes for Applied Polymer Re-search IAP, for Microstructure of Materials and Systems IMWS, for Molecular Biology and Applied Ecology IME, for Mechanics of Materials IWM and for Silicate Research ISC have now optimized the characteristics of synthetic rubber. “Our synthetic rubber BISYKA – that’s a German abbreviation for “biomimetic synthetic rubber” – actually has superior characteristics to natural rubber,” says Dr. Ulrich Wendler, who heads up the project at the Fraunhofer Pilot Plant Center for Polymer Synthesis and Processing PAZ in the German municipality of Schkopau. Fraunhofer PAZ is a joint initiative be-tween Fraunhofer IAP and Fraunhofer IMWS. “Tires made of the synthetic rubber lose 30 percent less mass than equivalent tires made of natural rubber. On top of that, the synthetic tires have only half the tread loss. Furthermore, the synthetic rubber can be produced on an industrial scale using existing plants and equipment. This means that the synthetic rubber offers an excellent alternative to natural rubber – including the do-main of high-performance truck tires.” Targeted analysis of dandelion rubber But how did the researchers achieve this higher performance? At Fraunhofer IME, scientists investigated rubber from dandelions. Like the rubber from rubber trees, 95 percent of dandelion rubber consists of polyisoprene, while the remaining percentage is made up of organic components such as proteins or lipids. The advantage of dande-lion rubber over tree rubber: the former has a generation succession of just three months as opposed to seven years for the latter. That makes rubber made from dande-lions an ideal starting point for investigating the influence of organic components on the rubber characteristics. To this end, the Fraunhofer researchers eliminated the key organic components involved in a targeted manner. After they had identified the or-ganic components that were important for abrasion behavior, the researchers at Fraun-hofer IAP synthesized the BISYKA rubber out of functionalized polyisoprene with high micro-structural purity and the respective biomolecules. Their colleagues at Fraunhofer IWM and IMWS then investigated the characteristics of the rubber variants thereby ob-tained. To do this, they used extensional crystallization: If you stretch natural rubber to three times its length, crystalline regions form – the rubber hardens. “The extensional crystallization of BISYKA rubber equals that of natural rubber,” explains Wendler. When making truck tires, the rubber is usually mixed with carbon black – which is where the black color comes from. Increasingly, however, manufacturers are adding sil-icates to the mixture instead of carbon black. This is where the expertise of Fraunhofer ISC comes in: At the institute, scientists investigate how new kinds of silica fillers can lead to optimum alternatives to natural rubber in the automotive industry. Synthetic rubber yields impressive results in practical tests After the development of the BISYKA rubber, it was tested: Would it do what its exten-sional crystallization promised? The researchers handed over this question to an exter-nal and thus independent partner to investigate: Prüflabor Nord. For this purpose, four car tires were manufactured with a tread made from BISYKA and they were then com-pared with tires with a tread made from natural rubber. The tests were carried out di-rectly on a car that drove 700 circuits in one direction and then 700 circuits in the other direction. And the result? While the natural rubber tire was 850 grams lighter after the test and lost 0.94 millimeters of tread, the BISYKA tire lost merely 600 grams and 0.47 millimeters of tread. The rolling resistance of the synthetic rubber was also better: While the natural rubber achieved a score of C on the traffic light labelling of the rolling resistance, BISYKA achieved the higher score of B. “So far, we have only carried out initial tests with the BISYKA tire blend, but they are extremely promising. As the next step, we want to further optimize the BISYKA rubber. This concerns above all the proportion and the composition of the organic components. At the same time, we will adapt the formula of the tread compound for truck tires to the new rubber,” says Wendler. Currently the researcher and his team are looking for cooperation partners who will bring the product to the market.
Throughout the day, our skin is exposed to a range of hostile elements: wind, rain, sunlight, central heating, vehicle emissions... It is vital therefore to ensure it receives proper care. Most importantly, this means choosing a skincare product that is suitable for your type of skin. Fraunhofer researchers have now come up with a commercially viable method of producing a facial skincare product that is precisely tailored to the actual condition of your skin. What’s more, it contains nothing but essential ingredients. Drugstore shelves are crammed with different face creams. But which one is best for your particular type of skin? Making the right choice can be a tricky business, not least because other factors are involved, such as the season of the year, your current stress levels, hormonal balance and age. All of these can have a significant impact on the current condition of your skin. Lots of women would love to have a face cream that is just right for their needs. Such a personalized skincare product is now available from the company Skinmade. A spin-off from the Fraunhofer Institute for Manufacturing Engineering and Automation IPA, Skinmade has been set up by Viktor Balzer, an industrial engineer at Fraunhofer IPA, and Dr. Lars Rüther, a molecular biologist from Dermatest GmbH. Skinmade’s Personal Skin Care is already on sale at three outlets of the cosmetics chain Douglas – in the German cities of Frankfurt, Hamburg and Sindelfingen – and is scheduled for rollout in all major German cities by the end of 2019. Batch-size-one production at low unit costs Developed on the basis of five years of research plus the combined know-how of a multidisciplinary team of IT specialists, engineers, dermatologists, pharmacists and biologists, this innovative product has undergone extensive dermatological testing with live subjects and is fully compliant with the EU regulation on cosmetic products. At its heart is an innovative cyber-physical production system that will deliver a jar of personalized skin cream at the press of a button – and for a reasonable price. The cost to the consumer for a 30-milliliter jar of Skinmade Personal Skin Care is 40 euros. The touchscreen-operated unit comes in a compact housing the size of a closet. This comprises the entire production process, starting with technology to measure the skin’s natural hydration and lipid levels, and including the production control system as well as all the raw materials plus jars and caps for the cream. At the end of the process, the finished product is proffered on the machine’s dispensing tray. “We’re basically talking here about ‘batch-size-one’ production, i.e., about being able to produce customized products on a profitable basis,” says Balzer. In effect, he and a research team from Fraunhofer IPA have developed a patented system that enables the production of batch-size-one items at an increasingly low unit cost thanks to the exploitation of economies of scale and other synergies. “A customized product normally entails a high unit cost. But we’ve been able to get around this and produce our cream for a relatively low retail price. Not that I’m going to tell you how our patented system works! Let me just say that the various dosage, homogenization and purification steps are all integrated in one single process. That’s what makes it so fast.” The system is capable of dosing very fine concentrations of individual ingredients in quantities as small as three microliters. Also underpinning the success of this concept is the team’s specialized knowledge in the field of dermopharmacy – i.e., the effect that certain ingredients have on key biomarkers. Produce your personalized cream in seven minutes The first step is to measure the skin’s natural hydration and lipid levels with spot checks on the forehead, cheek and below the corner of the mouth. This process measures various biomarkers in order to gage the actual condition of the skin. Using a method known as corneometry, the level of skin hydration is determined. This relies on a measurement of the relative permittivity of the uppermost skin layer, the stratum corneum, which is around 20 micrometers in depth. Another method – sebumetry – serves to quantify the level of surface lipids on the skin. This is based on a technique known as grease-spot photometry. Here, an opaque strip of material is placed on the skin for a period of 30 seconds. Contact with the sebum in the skin renders the strip translucent. Analysis of the degree of translucency then serves to determine the lipid levels in the skin. A further technique is employed to measure the skin’s elasticity. The data from these various measurements is then analyzed by means of self-learning algorithms and neural networks programmed by the team. On this basis, the system can then calculate how much of which ingredients should go into the personalized skin cream. Balzer and his team have also put together the training datasets required for machine learning. The entire cyber-physical production system is controlled by means of a cloud solution. Once the data have been analyzed, the results are fed into the machine’s control system. A mere seven minutes later, the customer is presented with a 30-millimiter jar of face cream customized to their precise skin requirements. Customers can also specify their preferred fragrance and consistency. Skinmade recommends repeating the analysis after six weeks. That way, it can be determined whether the skin has altered and whether a new formulation might be more appropriate. In other words, customers can be sure of always getting a cream that is right up to date with their current skin condition. “A standard skin cream can never be as effective as a customized one,” says Rüther. “It’s possible that a product from the shelf contains ingredients at a concentration you don’t need. That means you might end up getting too much or too little. Plans for a mini skin analyzer for home use In the future, customers will also be able to book skincare consultants – equipped with a mobile skin analyzer – for home visits. Following analysis, skin data will be processed in the cloud. The finished product is then dispatched by mail. Alternatively, customers will be able to order their very own mini skin analyzer online, complete with special app, and then carry out their own skin measurements, before sending the data to Skin-made. This option is scheduled for rollout in 2020. Meanwhile, the team at Skinmade is busy exploring further customized items. The latest project is to put together a bespoke set of personal care products – comprising cleanser, tonic and serum – in which each item is perfectly matched with the others.
