BEIJING--(BUSINESS WIRE)--Nutanix (NASDAQ: NTNX), a leader in enterprise cloud computing, today announced the private cloud deployment of SAIC Volkswagen, a Sino-German joint venture between Shanghai Automotive Industry Corporation (SAIC Motor) and Volkswagen Group. The speed and ease of deployment enabled the automotive giant to continue innovating efficiently without worrying about the fundamental IT support needed across its many departments ranging from research and development (R&D) to manufacturing, transportation, logistics, car sales and consumer relations programs. SAIC Volkswagen’s business critical applications – including the corporate internal management system, reporting system, and process management system, as well as the POC test server for new product solutions – are supported by over 1,000 servers with a lean, 20-strong IT team. The deepening of IT applications, which requires web-scale infrastructure with higher flexibility and leaner scalability, has increased the need for efficient delivery of information services for a company that sells more than 2 million cars a year. The tight coupling between daily operations and company objectives mandates a more efficient IT infrastructure. SAIC Volkswagen’s IT team faced three challenges in operations and maintenance during the past years. First, there were the management and maintenance costs surrounding their legacy three-tier datacenter. The costs of each tier (compute, networking, and storage) had increased significantly, compounding with the resource needs of the rapidly expanding applications and services needed to support business growth. Second, due to the diversity of applications, each with unique requirements, it was difficult to match compute needs with available storage performance capabilities. The situation caused deployments where applications were underutilizing their hardware or attached to storage that far exceeded the performance need. This level of waste was unacceptable to SAIC Volkswagen. Third, the options to scale-up the storage was limited by the inherent complexity and technical limitations of the storage vendor. In addition, it also required lengthy internal procurement process, causing delays in meeting the demand from the various departmental application owners. Seeking to overcome these challenges, SAIC Volkswagen completed thorough market analysis concluding on the decision to run a private cloud deployment proof of concept (PoC) with Nutanix. During the PoC, it was discovered that procurement and maintenance costs were reduced while the internal procurement process was streamlined. This drastically reduced the response time to requests from various business departments delivering more agile support with better control functionality. “After the initial test, we found that the Nutanix enterprise cloud solutions were very much consistent with SAIC Volkswagen’s plan for private cloud in terms of both functions and performance. Some of the features are so impressive that they went beyond our expectations,” said Wang Chunxiao, project lead at SAIC Volkswagen. “In addition, the distributed storage of Nutanix saves us the trouble of buying the entire fibre-optic network and centralized storage, which makes it very appealing and advanced from the cost, management and horizontal expansion perspectives.” Wang was particularly impressed by the ease of use and management of the Nutanix solution, specifically around “one-click” system upgrades. “To upgrade the system, all you need to do is click the button to upgrade. All the Nutanix nodes would be automatically upgraded in the background, and the front-end users would not even notice the upgrade during the whole process.” A complete ‘hassle-free’ solution, is how he described it. Tasks in the previous environment, based on manual operations, which would typically take two days now only required one to two hours. The efficiency brought by an automated one-click process makes Nutanix a perfect fit for teams with limited manpower, letting the IT teams focus on higher value tasks for the business. The rapid deployment and launch of the Nutanix solution not only accelerated the R&D of new products and shortened the time to value, but it also saved valuable space and power in SAIC Volkswagon’s datacenter. The Nutanix platform only required 4U of rack space, drastically lower than the minimum of 20U required by the previous three-tier solution. “During this age of digital transformation, traditional companies have all embarked on the path of IT transformation one way or another,” said Matt Young, SVP and Head of Asia-Pacific and Japan at Nutanix. “For companies that have invested heavily in IT applications, the optimizing of IT architecture has become an effective way to boost competitiveness. As a global leading automotive company, SAIC Volkswagen has a complex structure and a large business portfolio, and its experience of private cloud infrastructure can be of high relevance and educational value to many similar organizations.” Nutanix makes infrastructure invisible, elevating IT to focus on the applications and services that power their business. The Nutanix Enterprise Cloud Platform leverages web-scale engineering and consumer-grade design to natively converge compute, virtualization and storage into a resilient, software-defined solution with rich machine intelligence. The result is predictable performance, cloud-like infrastructure consumption, robust security, and seamless application mobility for a broad range of enterprise applications.

In order to improve the performance of switched reluctance driving system, it is necessary to build an accurate switched reluctance motor (SRM) model. In this paper, a nonlinear flux-linkage model and a torque model of SRM are presented by using the measured accurate flux-linkage data, torque data and nonlinear mapping ability of BP neural network, which is based on fast self-configuring algorithm. In contrast with the traditional models, these two models have the abilities of fast convergence in training, good learning generalization, small network scale and easy real-time control. An experiment is carried out to demonstrate the accuracy and feasibility of the presented models. The result shows that the models have a better accuracy than the previous ones and are good for further optimization of the energy conversion and reducing the torque ripple. ©2010 IEEE.

It is well-known that the DoubleMinOver classifier as an extendibility of MinOver was developed to provide a maximum margin solution with a bias. But, it can be found that the DoubleMinOver algorithm only classifies the vector pattern and fails to work in the pattern represented with the second-order tensor. In this paper, we propose a novel DoubleMinOver classifier named STDoubleMinOver that can directly classify the second-order tensor pattern. Compared with the existing DoubleMinOver with only one weight w, the proposed STDoubleMinOver induces two weight vectors u and v so as to deal with the second-order tensor. The experiments here have demonstrated that the proposed STDoubleMinOver has a superior classification to the vectorized DoubleMinOver. © 2010 IEEE.

To realize lightweight scheme selection for car-body effectively, a method of lightweight scheme selection for car body based on multi-objective satisfaction decision mechanism was proposed. Based on the data performance analysis of the different schemes, aiming at weight reduction, cost deduction, and performance improvement, measuring weight coefficient of every object according to the importance for the lightweight scheme selection, the multi-objective optimization of the lightweight scheme selection was constructed. Multi-objective satisfaction decision mechanism was introduced to evaluate the general satisfaction of different lightweight schemes, and the largest satisfaction scheme with validation as the appropriate scheme was obtained. The effectiveness of this scheme was verified by the case of the car body engine hood.

The vehicle collision warning system (CWS), enabled by recent advances in positioning systems and wireless communication technologies, plays a significant role in reducing traffic accidents. Since vehicle position is the most frequently exchanged information in vehicular networks and the key information in collision prediction, it becomes crucial to establish a strong level of trust in the positions, especially in active safety applications. To this end, in this paper we proposed a cooperative collision warning system (CCWS) based on digital map and dynamic vehicle model fusion. In CCWS, vehicles broadcast self-relevant information to neighbor vehicles periodically. In contrast to conventional methods that use only vehicle’s dynamic models, the proposed system takes the information provided by a digital map into consideration to improve the accuracy of vehicle position estimation. Each vehicle calculates whether a potential collision may occur by fusing the dynamic vehicle model, digital map and the information received. If such a dangerous situation is predicted, an alarm will be triggered to inform the driver. Our experiment results show that the CCWS has a better performance in vehicle position estimation and collision prediction compared with the CWS without considering cooperation. © Springer International Publishing Switzerland 2015.

The electrification of vehicles has caused a great change in the characteristics of noise, vibration and harshness. A range-extended electric vehicle has complicated noise and vibration problems because it behaves both like a traditional vehicle and like a battery electric vehicle as well as having its own specific noise, vibration and harshness properties. Therefore, increasing attention should be paid to these issues. This paper is intended as a contribution to the current research on the noise, vibration and harshness of a range-extended electric vehicle. The electric driveline, the auxiliary power unit and the accessories, including the power steering pump, the electric vacuum pump and the air conditioner compressor, are tested and their noise, vibration and harshness performances are analysed. The results indicate that the high-frequency noise of the electric driveline and the vibrations of the auxiliary power unit and the air conditioner compressor are crucial noise, vibration and harshness issues of a range-extended electric vehicle. Some improvement methods are implemented or proposed for better comfort in the passenger compartment. Application of a material which is sound insulating and sound absorbing proved to be an effective countermeasure. The design and refinement of a vibration isolation system for the auxiliary power unit and the air conditioner compressor are of great importance. A reduction in the low-frequency torsional resonance of the auxiliary power unit shaft during a start-stop process is a new problem compared with that of a conventional engine. It is necessary to find a well-balanced compromise between the expected acoustic feedback and the power demand. © Institution of Mechanical Engineers.

In the process of mechanism creative design, structure synthesis is the primary and the most important issue. This paper proposes a systematic and automatic synthesizing method of fixed-axle gear sets by means of morphological analysis. And the process is implemented to synthesize Electrified Mechanical Transmission (EMT) schemes which are parallel hybrid electric transmission composed of fixed-axle gear sets. First, independent design parameters as well as feasibility constraints and consistency conditions are defined by analyzing the structure and functions of EMT. According to these boundary conditions, structure variables such as the quantity of components and their connection relationship are solved. Then, the scheme quantity of each structure type is synthesized. Secondly, based on the abstraction of practical mechanisms with topology models, the corresponding adjacency matrixes are derived, and they are used to filtering unqualified schemes and retrieve all potential transmission paths of the remaining schemes. These potential transmission paths are further used to find out the layout and operating mode of each scheme. Finally, all schemes satisfying the structural and functional requirements are synthesized. For example, one EMT prototype is built based on one of the final schemes found and an ICE car is modified to adapt to such transmission. Vehicle test results verify the effectiveness and feasibility of the chosen transmission scheme. © 2015, The Korean Society of Automotive Engineers and Springer-Verlag Berlin Heidelberg.
