In the future energy system, the share of renewable energy will increase. The intermittent renewable energy will challenge the stability of the energy system, hence, it requires the demand side has the flexibility to meet the fluctuation of energy production, and buildings are accountable for 40% of total energy consumption within the world. The building could be a flexibility supplier for the energy system; also the large thermal mass of the building is ideal energy storage. This paper presents a new construction low energy building located in Copenhagen, Denmark, to demonstrate the energy flexibility possibility by utilizing the new building's thermal mass; and the effect of weather impactors and internal gains in an indoor environment will be discussed.

Cyber physical systems are specified in a hybrid form, with discrete and continuous parts. Simulating such systems requires precise data and synchronization of continuous changes and discrete transitions. However, in the first design steps, missing information forbids numerical simulation. We present here a new qualitative language for qualitative simulation of cyber physical systems, which consists in computing the relationships between the system variables. This language is implemented in the Diversity symbolic execution engine to build the traces of the system. We apply this approach to the analysis of SysML models, using an M2M transformation from SysML to a pivot language, an M2T transformation from this language to Diversity and an analysis of the traces obtained by Diversity to build the qualitative behaviors of the system.

Global warming, which is currently one of the greatest environmental challenges, is caused by carbon emissions. A report from the Energy Information Administration indicates that approximately 98% of CO2 emissions can be attributed to energy consumption. The trade-off between efficient and ecologically sound operation represents a major challenge faced by many organizations at present. In addition, numerous companies are currently compelled to pay a carbon tax for the resources they use and the environmental impact of their products and services. Therefore, an energy consumption system can generate actual financial payback. Green information technology involves various approaches, including power management, recycling, telecommunications, and virtualization. This paper focuses on comparing and evaluating techniques used for reducing energy consumption in virtualized environments. We first highlight the impact of virtualization techniques on minimizing energy consumption in cloud computing. Then we present an experimental comparative study between two common energy-efficient task scheduling algorithms in cloud computing (i.e., the green scheduler, the power saver scheduler). These algorithms are discussed briefly and analyzed. The three metrics used to evaluate the task scheduling algorithms are (1) total power consumption, (2) data center load, and (3) virtual machine load. This work aims to gauge and subsequently improve energy consumption efficiency in virtualized environments.
全球变暖是目前最大的环境挑战之一,它是由碳排放引起的。美国能源情报署(Energy Information Administration)的一份报告表明,大约98%的二氧化碳排放可归因于能源消耗。在有效和无害生态的操作之间进行权衡是目前许多组织面临的一个重大挑战。此外,许多公司目前被迫为他们使用的资源以及他们的产品和服务对环境的影响支付碳税。因此,能源消耗系统可以产生实际的财务回报。绿色信息技术涉及各种方法,包括电源管理、回收、电信和虚拟化。本文的重点是比较和评估在虚拟环境中用于降低能耗的技术。我们首先强调虚拟化技术对最小化云计算中的能源消耗的影响。然后,我们对云计算中两种常见的节能任务调度算法(即绿色调度和节能调度)进行了实验比较研究。对这些算法进行了简要的讨论和分析。用于评估任务调度算法的三个指标是:(1)总功耗、(2)数据中心负载和(3)虚拟机负载。这项工作旨在衡量并随后提高虚拟化环境中的能源消耗效率。

Software engineering paradigms such as service-oriented architectures are increasingly often applied in the field of factory automation. Functions like robot motion planning or object recognition are provided by cloud services. A crucial architectural aspect is the granularity, i.e. the scope and size of individual services. In our case study, we examine a service-based object recognition application for a robotic assembly use case. We implement three different granularity levels, measure their communication and computation times and discuss further architectural features. The fine-granular approach encapsulates individual image processing operations as services, which have high reusability but impose large communication overheads. The medium granularity approach is object-wise and offers best reuse efficiency and cohesion. The coarse solution offers the best performance.

The use of devices that can produce audio such as a pair of earphones and headphones in the maximum audio volume can cause damage to our hearing due to hearing loss. Hearing loss will affect a person's hearing quality to hear low volume or intensity. There is an Audiometry Test to check one's hearing quality whether it is still above or below the normal hearing threshold. It utilizes a special tool and is very useful for detecting a person's hearing loss early. The test's procedure is to play a tone that has a different frequency and intensity. Advancement of mobile technology makes a possibility to provide Audiometric Test on a smartphone device. This method will provide a convenience and an access rights for anyone to know early if they have hearing impairment without the needs of special devices. To find out the possibilities, we made an application by designing and testing 3 different smartphones and 4 pairs of earphones. The experimental results were tested using the Wilcoxon Signed-Rank Test to test the stability of mobile applications when using smartphones and earphones from different factories. Statistical tests are conducted to find the type of hardware that is suitable for use in a mobile application. This is done based on the availability of the hardware during the study. The sample was carried out on 30 people using convenience sampling method through Test Audiometry of mobile application. The procedure used on application of Audiometric Test comes from Mayfield Clinic standard. The results prove that the Test Audiometry application on mobile devices can run according to standard procedures. The testing results proved that the application can run as a simulation of an audiometry test. Statistic tests results suggest that a difference of the smartphones used in this testing does not have any effect on the outcome of the audiometry test result, but in-ear earphones show higher stability rate than regular earphones.

2225 hydraulic actuators are used to support the deformation of FAST(Five-hundred-meter Aperture Spherical radio Telescope) active reflector. For hydraulic actuator of different design schemes, the design based on bi-directional gear pump is selected based on prototype test, reliability and maintainability. Of the 2225 actuators, 2075 are designed to meet maximal load of 7 tons, 140 of load 10 tons, and 10 of load 15 tons. In operation of observation, for each of the time ticks(Interval 500ms), the piston position precision of the hydraulic actuator is controlled to be better than 0.25mm, which is over ten times better than the typical node precision requirement of the active reflector. Each of the actuator is physically connected to the control room by optical cable for transmission of control commands and actuator status. Each of the actuators is further designed to meet the shield effect requirement for the radio telescope. With both good reliability and easy maintainability, the actuators worked well to support the scientific observation of the giant telescope.

OPC Unified Architecture (OPC UA) is considered as a significant part of future industrial networks to provide a modular and well-structured access to machine data. In this paper, we proposed a method for parsing OPC UA binary content and a novel two-phase approach for extracting features from OPC UA. The developed method is able to parse OPC UA content sequentially and to transfer data in a structured way. For extracting features from the payload based on a new string representation, an algorithm extracts all numbers from strings and processes them separately to the letters in the first phase. The used regular expression replaces all integers and floating-point numbers with a special character. In case of not identical strings, the representation is done by an ASCII-distribution as well as an edit-distance in the second phase. On the one hand this approach documented how OPC UA data is parsed and how to use the data in subsequent steps to run analyses. On the other hand the extracted string representations are more accurate than any existing approaches and thus, are usable for machine learning algorithms.

NoSQL databases have become very popular in the last few years. Graph databases, as a major NoSQL database type, are used for many problems. In relational databases, conceptual modeling is very important, for which Enhanced Entity-Relationship (EER) model is widely used. Since an EER schema can be considered as a special graph, the idea is given: try to realize it in a graph database. I used Neo4j database management system as a graph database. This paper introduces the Cypher statements and formatting in Neo4j to store and visualize EER.
