From science to the humanities, mathematics and logical thinking ability also affect every aspect of computer science education. To foster mathematics logical thinking and problem-solving ability in primary and secondary schools, students not only require to learn to read, writing, and arithmetic, but also need to understand the abstraction of mathematics operations and logical thinking processes. Therefore, this study uses visual programming language as a basis, i.e. Scratch 2.0 offline edition, to introduce abstraction of mathematics operations. Scratch 2.0 can empower learners using graphical elements to solve mathematics problems with a smooth learning curve through user-friendly programming interface. However, the latest version of Scratch 2.0 does not include enough functions for abstracting mathematical blocks. Consequently, this study integrates Scratch programming environment with math library of Python language to expand functionality and improve usability of Scratch. Moreover, learners are expected to learn and practice more about mathematical thinking through those additional Scratch building blocks.","PeriodicalId":281088,"journal":{"name":"2016 International Computer Symposium (ICS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125350577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the implementation is practically a challenge due to the limitation of cost, space, and complexity. Though the millimeter-wave (mm-wave) transmission can greatly save the space for deploying numerous antennas, the demand on the numerous RF chains increases the implementation cost significantly. The hybrid structures of sub-array antennas are then developed to alleviate the cost, where the entire array is grouped into several sub-arrays. All antennas in a subarray share a common RF chain, which greatly reduces the complexity. Furthermore, the downlink channel state information (CSI) is crucial for several pre-processing technologies such as precoding. Nevertheless, the CSI estimation is difficult due to the large dimension of a channel matrix. Accordingly, CSI estimation by the structured channel matrix is attractive since only few unknown angle-of-arrivals (AoA) and deterministic signatures can model the CSI. Estimation of CSI is equivalent to estimating the AoA. In this paper, we propose a new AoA estimation by using estimating signal parameters via rotational invariance technique (ESPRIT) for the massive MIMO system with two kinds of hybrid subarrays, referred to side-by-side and interleave sub-arrays. Numerical results validate the proposed AoA estimation and show that the proposed AoA estimation with side-by-side sub-arrays can approach to the fully-digitized arrays while keeping a lower computational complexity.","PeriodicalId":281088,"journal":{"name":"2016 International Computer Symposium (ICS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124672615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To foresee such heavy burden in each eNB, Device-to-Device (D2D) technology is a promising solution to do data offloading while maintain acceptable service quality. In this paper, we first target on two different D2D interfaces, Wi-Fi and LTE direct, and propose an efficient multi-radio selection scheme by dynamic programming design approach for video streaming in wireless cellular networks. To minimize total LTE radio resource usage, we leverage D2D technology and adaptively select the different transmission links to meet QoS requirement of each user. Since the data rate of Wi-Fi transmission link is hard to correctly evaluate, we conduct a series of experiments under realistic interference environment to measure the actual capacity of Wi-Fi transmission links. Besides, we also study related works about general capacity predict model to take both measurement and mathematical model into consideration for designing our solution. The simulation results show that the proposed scheme can significantly reduce the LTE radio resource usage and successfully do data offloading for each eNB in wireless cellular networks.","PeriodicalId":281088,"journal":{"name":"2016 International Computer Symposium (ICS)","volume":"72 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130351595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an important issue to reduce network traffic and increase the user quality of experience (QoE). Therefore, there have been in-network caching schemes to cache the content fetched by users in proxy servers. Recently, software defined networking (SDN) was proposed to implement the network function by the virtualization function. Programmers can implement the customized network functions by the SDN architecture. This paper proposes an extended SDN-based caching service architecture, abbreviated as ESC. The ESC decomposes the function of inspecting incoming traffic, making cache decision, and storing cache content into three types of network entities: an extended OpenFlow (DPI-based) switch, a cache controller, and cache nodes. This design can lessen the load of single network entity. Moreover, the ESC can cache different parts of a video in distinct cache nodes. The distributed content storage mechanism can increase the cache capability and the system flexibility. In addition, we use M/M/1 queuing model to analyze the average queuing delay time, and compare the ESC queuing delay time with the C-flow and the OpenCache. The results in numerical analysis show that the ESC average queuing delay is shorter than the other two.","PeriodicalId":281088,"journal":{"name":"2016 International Computer Symposium (ICS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129232810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EBPR is based on void-aware pressure routing (VAPR). In VAPR, determination of beacon cycle is related to node velocity. However, the node velocity is difficult to get without assisted positioning system, and it has certain difference at different positions. EBPR proposes a different method to determine cycle based on sensor node's feedback without knowledge of node velocity. Besides, EBPR introduces the residual energy into the next hop selection process to balance energy consumption of node and postpone the sparse process of network. At the same time, a routing reconstruct mechanism is proposed to help node who missing the routing construct process to update routing information with the help of redundant information in aware packets. In this paper, we simulate the two protocols using OMNeT++. Result shows that two protocols have almost the same data delivery ratio. However, at the aspect of lifecycle, EBPR can extend by 10% ~ 30% under low water velocity. This advantage will decrease as the increase of node velocity, but not weaker than VAPR.","PeriodicalId":281088,"journal":{"name":"2016 International Computer Symposium (ICS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124505446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
